Culture in International Business - Essay Example In this way, management’s ability to understand the levels of nuance and meaning that exist within such a group is a key determinant as to whether the employees themselves will feel an overall sense of appreciation and inclusion with respect to the company as a whole. Such an emphasis on attempting to relate to and understand the cultural considerations with relation to foreign operations is something that likely cannot be overemphasized due to the primal nature of how human beings identify with their culture and then project these identifications within the workplace environment (Lung et al 2012). As such, rather than seeking to change the culture of the given work as a means to reflect a more domestically centric version of the firm’s operations, it is the duty of the manager to ensure that equal consideration is given to the unique cultural needs of the employees that he/she is responsible for. Although there already exists a large body of scholarship on the needs of the international business to recognize and focus upon the unique cultural needs of their component parts, as previously stated, this is truly something that cannot be underemphasized. Moreover, due to the fact that the author helps to lay out a quantifiable and descriptive list of ways in which such a process can be effected in order to achieve a better quality of product from the component parts of an international firm’s units.

With this technology we provide our customers with great service and delicious meals at an unbelievable price. We will become the best restaurant in the area that provides our customers with Mexican, Afro-American cuisine. The employees of Greg’s restaurant will be like family. Organization Vision Vision is the strategic planning of a company to achieving its goals. â€Å"A vision statement presents the firm’s strategic intent that focuses the energies and resources of the company on achieving a desirable future† (Pearce Robinson, 2009, p37). The aim for Greg’s restaurant is to in the next 2-4 years to be above and beyond the competition and to expand the business to other areas within the city. The future planning of the restaurant is to come up with menu items that will continue to help the business to prosper. Guiding principles: Culture, social responsibility, and ethics Greg’s restaurant is following many values and cultures according to the needs of customers. The menu items of the restaurant represent different cultures that can attract customers of different nationalities and societies. Greg’s restaurant is multi- cultural and offers a wide variety of menu items that everyone can enjoy. Greg’s restaurant gives priority to the values of honesty and integrity in full support of their valued patrons. The restaurant also offers specials throughout the week and also issues coupons to get half off on certain menu items. The business is using products that are environmentally friendly and to help protect the environment and health of the community. The vision, mission, and values statement of the restaurant will provide the framework, structure and the company’s goal. The vision is the end goal the restaurant wants to achieve whereas the mission and the values will provide the business with the everyday activities the business already performs and also the structure and framework for the strategic plan for the business. The business will address customer needs by providing good service and meals to each and every patron that enters the establishment. All customers will get the same fresh meal the first customer to the last customer. The staff will act in a professional manner and provide great customer service and our suppliers along with the restaurant will serve the freshest ingredients available. Organization Strategic Direction Without strategic direction the business will not be able to accomplish its mission or vision. So it is very important that a company has a strategic direction for the implementation of its mission and vision. Strategic direction is defined as strategies made by a business or company to fulfill its mission. Strategic direction helps the owner and employees to know what is needed or required to achieve the mission of the company. Customer needs and competitive advantage At Greg’s restaurant it is important for the business to provide a relaxed comfortable atmosphere to the customers so they can like at home. At Greg’s restaurant there has been mechanisms added to provide the customers with the necessary seating and waiting areas to help them feel more comfortable at the restaurant. It is also a positive direction the company has taken is there is no priority of any culture or religion to dine at the restaurant. Honesty is a key element that we strive when dealing with patrons. Strategy planning helps the company review the mission and vision and to make sure that the company is headed in the right direction on achieving the goals. The future planning and vision of the restaurant has an impact on the restaurant strategy and it could impact the way the business will do over the next few years. The business has to utilize its vision and mission statements to make new decisions or to improve on the decisions it makes about the future of th e business and what is going to benefit the business. SWOTT Analysis In the restaurant business and by being new to the industry which is very competitive a SWOTT analysis plays a key role and is needed for a business to succeed. Greg’s Family Restaurant sets itself apart from other restaurants by servicing their customers with excellent customer service and meals. When analyzing a business one has to look at the internal and external factors that affect the company. A SWOTT analysis provides a breakdown of all these factors even factors that could affect a business internally and externally. SWOTT analysis is a tool a company uses in forming a strategic plan. It is the most effective tool a company uses to determine and uses for a strategic plan. SWOTT stands for Strengths, Weaknesses, Opportunities, Threats, and Trends a company must face. Business can use SWOTT as a tool to create and overview of the organization strategic situation. (Pearce Robinson, 2009). For a new establishment like Greg’s Restaurant a SWOTT analysis is necessary to establish and compare where it is in a competitive market. When operating any type of business preparation is a key element: looking into as many potential options as possible is a must to prevent the company from profit loss along with the shareholders but in this case it is Greg’s stakeholders at risk. By eliminating all possible threats and creating opportunities with limited financial resources and concentrating on the long- term goal is the key to the success of the business and the future. SWOTT provides basic framework for business existing or new. More opportunities can be created by eliminating various weaknesses. External forces which are opportunities, threats, and trends are sets of uncontrollable factors the restaurant face and must overcome to succeed in the restaurant business. After conducting a SWOTT analysis legal and regulatory, economic, technology, Global and social trends were found external forces that need to be addressed. Legal and Regulatory Because of the external forces of opening a new restaurant or possible refitting and exiting building you will have to deal with the zoning laws. Restaurants need licenses and permits to operate or a food service establishment permit, alcohol license and food safety permit. Food safety health codes vary from state to state but restaurant businesses have to abide by the rules and laws that are put forth. The rules and regulations are to help protect the consumers and business. Economic Information regarding to products, services, tools, technology, and suppliers will compromise the economic environment of the restaurant. In 2001 California restaurants are projected to register 63.8 billion in sales, every $1 spent generates additional $1.19 in sales for the state economy. In 2010 there were 62, 794 eating and drinking places in California; every extra $1 million spent in California’s restaurants generates an additional 23.8 jobs in the state. In 2012 California restaurants employ 1,445,000 people (www.restaurant.org). Macroeconomics is very sluggish at this point in time. Inflation is at a high and banks are increasing interest rates. People are not spending as they did in the past they are more frugal with their finances. With the housing market in a slump, unemployment on the rise and with energy prices on the rise it is giving the restaurant industry a hard time. Changing labor conditions and cost is affecting smaller family type restaurants to eventually lose their business. Globalization Globalization shows opportunity for Greg’s restaurant to expand outside the United States. Forming a Limited Liability Company (LLC) it protects your personal assets from any liability the business incurs. If the owner plans on setting up a restaurant in different locations have separate LLC for the location. Social Socially people love to meet, dine, and have a drink and fun. But given the economic conditions of today it is hard for people to dine like they once did in the past. People are also concern about eating healthy and given the increase of a lot of food recalls in the past. Social media is also playing a big role in the marketing aspect of the restaurant industry. Technology Technology in the restaurant industry is very vital to the everyday operation. There is software available to track inventory, supplier orders, and to manage food orders. Technology is being developed every day to improve the way restaurants do business. Managers are no in more control of their staff with remote monitoring systems. Internal forces are more controllable factors a business can use to improve the operation and its path to success. After conducting an internal evaluation these were the factors the business came up with that is logical: strategy, strategic capabilities, and structures. Strategy In order for the restaurant to grow and expand a strategy has to be designed to which the business should offer products and services which customers could not receive from anywhere else. As far as strategizing the restaurant has the use of resource control which is key i.e. (operations, finance, supplies, and manpower). Strategic Capabilities Strategic capabilities play a big part in the restaurant industry. A business can create its own uniqueness through its marketing and strategic capabilities. A well- organized supply chain, a well trained staff, and a competent management team are strategic capabilities that will help the restaurant to fulfill its vision. The business also needs to consider its ability to manage working capital, expecting manpower issues and customer expectations and the ability to think ahead of the competition. As the industry changes over a period of time the threats and opportunities the restaurant will face the strategies and model of the business will have to adapt to these changes to meet the needs of the customers. It is very critical management focuses and maintain a product mix that works well for the business. The restaurant should position itself to reach specific demographic groups. Issues and Opportunities As mentioned in internal forces issues that are apparent is the lack of interactions between the employees. With these issues it allows opportunity to create meetings between employees and management. These meetings will allow staff to feel they belong and part of the family. It also allows employees to express what is working and not working for the business and what need improvement since the staff are the ones interacting with the customers. Balance Scorecard To develop a Greg’s Family Restaurant a balance scorecard is essential. It is key component for defining the goals and targets of a business as well as the mission vision and SWOTT analysis. A balanced scorecard is, â€Å"A set of four measures directly linked to a company’s strategy: financial performance, customer knowledge, internal business processes, and learning and growth† (Pearce Robinson, 2009, p. 202). Financial Perspective/ Shareholder Value A well thought out vision and mission statement will facilitate the restaurant to achieve its target. The restaurants objectives are to increase the performance of the restaurant. The responsibility of the restaurant is to seek its customer satisfaction. Increase revenue, and also achieve financial stability. Customer Value Perspective Customers determine the success of the business. The ups and downs of the restaurants as well as the delivery of the services the business provides relates to the customers satisfaction. The more the customers are satisfied the better the business will do to attract more customers. Process/Internal Operations Perspective Strategic planning is very effective to give a nutritious meal to customers. This should be done in accordance with the customer needs. The most important thing is to determine the purpose and intentions of the strategy, because this will help the business towards its goals. The restaurant should set its goals and the path while keeping in minds the values and interest of the patrons. Customer comment cards should be available so customers can express their comments and concern. Greg’s family restaurant is always taking initiatives to improve service and products to increase their customer base. Learning and Growth Perspective Learning and growth process is the prospective to know about your business and if it is developing into the type of business you dreamt of. Learning in accordance to Greg’s family restaurant means to learn about the attitudes of the employees which are internal and customers which are external. Strategic planning within the growth and learning perspective should focus on employee training to have competent employees. Balance Scorecard Shareholder Value/Financial Perspective Strategic Objectives * Market share should increase * Net revenues should increase * Financial stability should be achieved * Production cost should be minimized Performance Measure * Revenue growth * Increased operating cost * Return on interest and capital Targets * 3-6 % market share increase over the next 3 years * 20% profit margin Customer Perspective Strategic Objectives * Focus on public interest * Quality food should be delivered * Community support * Improving brand name in market Performance Measures * New Menu Items should be offered * Awareness of brand in public Targets * 100% customer satisfaction * 15% increase in customers for the next 3 years Initiatives * Restaurant should expand to other cities * Benefits rewards program Learning Growth Perspective Strategic Objectives * Employees retention increased * Technology should be improved * Employee satisfaction Performance Measures * Customer satisfaction should improve * Employee turnover rate decreased * Surveys, monitoring and training Targets * 100% participation of all employees Initiatives * Staff training * Improved customer service * Analysis of Staffing References Pearce, J.

Disasterous Eating Disorders Essay -- Health Diet Essays

Disasterous Eating Disorders   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Americans obsessions with their bodies has become a hot topic lately. From personal observation and research, I have seen the obsession become more severe. Web sites dealing with eating disorders are some of the most commonly visited web sites. We have a problem. The obsessions are becoming too serious, even fatal. Americans today have become slaves to the diet and fitness industries, resulting in an increased number of eating disorder cases over the past few years. If Americans are not educated about the complicated causes and effects of eating disorders then the plague of the 90’s, eating disorders, is going to continue to kill. The following paragraphs are a start to the education. They deal with some of the causes but more important some solutions to eating disorders.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   According to the Encyclopedia Britannica, "obsessions are recurring or persistent thoughts, images, or impulses that, rather than being voluntarily produced, seem to invade a person's consciousness despite his attempts to ignore, suppress, or control them (Britannica 1). American's today deal with these thoughts about food, body image, imperfections, goals, flaws and how to deal with these. The thoughts are obsessive but they are real and at times, very intense. Sometimes the only way to cope with them, is to take drastic measures in ones behavior.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Obviously the rise in eating disorders and other obsessive illnesses have been addressed but why they develop and solutions to stopping them are still a hushed topic.

Home Security System

ACTIVE INFRARED MOTION DETECTOR FOR HOUSE SECURITY SYSTEM MIOR MOHAMMAD HAFIIZH BIN ABD. RANI UNIVERSITI MALAYSIA PAHANG ABSTRACT Nowadays, house security system becomes the best solution to overcome house intrusion problem when user is not in house. As we know, there are many types of house security system which is too expensive and difficult to use. For that reason, an effective house security system at low cost is built where user can also program the security system by their own.This project is focusing on developing a house security system with an active infrared motion detector which is controlled by microcontroller Intel 8051. The overall project is divided into two parts. The first part is concern on the hardware development where all electronics component are connected via the circuit design using wrapping technique. An active infrared, the magnetic sensor, and keypad are the input components while buzzer, indicator, and LCD display are the output components where it’ s all controlled by controller circuit. The second part is base on software programming to operate the hardware structure.Program for security system based on microcontroller Intel 8051 assembly language is assemble using ASM51 assembler to get the binary file thus, to load into external memory of the hardware structure via serial communication. The process of downloading and executing the program is done using HyperTerminal’s communication software to the microcontroller serial port. In order to achieve the best house security system, more detectors or sensors can be connected to the microcontroller output port where it can be reprogram by user using their personal computer at home. Read this  Chapter 2 – Why Security is NeededAs the result, the infrared motion detector is capable to detect motion while the microcontroller is capable to control the whole operation of the security system. CHAPTER 1 INTRODUCTION 1. 1 Background Motion detection is the action of sensing physical movement in a given area. Motion can be detected by measuring change in speed or vector of an object in the field of view. This can be achieved either by mechanical devices that physically interact with the field or by electronic devices that quantifies and measures changes in the given environment.There are two device of motion detection which is the mechanical device, and the other one is electronic device. In the mechanical device, a tripwire is a simple form of motion detection. If a moving objects steps into the tripwire's field of view then a simple sound device like bells may alert the user. Mechanical motion detection devices can be simple to implement, but at the same time , it can be defeated easily by interrupting the devices' mechanics like â€Å"cutting the wire†. While in electronic device, the electronic motion sensing such as motion detectors, can prevent such mechanical intervention.The principal methods by which motion can be electronically identified are optical detection and acoustical detection. Infrared light or laser technology may be used for optical detection. Motion detection devices, such as motion detectors, have sensors that detect movement and send a signal to a sound device that produces an alarm or switch on an image recording device. There are motions detector which employ cameras connected to a computer which stores and manages captured images to be viewed over a computer network.The applications for such detection are detection of unauthorized entry, detection of cessation of occupancy of an area to extinguish lighting, and detection of a moving object which triggers a camera to record subsequent events. The motion det ector is thus a basic idea of electronic security systems. 1. 2 Project objective The objective of this project is to build a house security system using microcontroller Intel 8051 based on active infrared motion detection. 1. 3 Project scope This project concentrates on a development of an active infrared motion detector for house security system.To develop the whole project, it consists of three methods which are the concept of security system, the electrical structure, and the software programming. The concept of security system is on the detection of movement using active sensor to trigger alarm controlled by the microcontroller Intel 8051. The electrical structure consist of two systems which are the active infrared circuit that used to detect or sense motion and the microcontroller Intel 8051 circuit, used to control the whole operation of the security system. While the software programming is base on the microcontroller Intel 8051 instruction sets.It contains a program design ed for a security system as an interaction to operate the electrical structure. 1. 4 Literature review Motion detectors are mainly used in security systems [4]. It is typically positioned near exterior doorways or windows of a building to monitor the area around it. Since motion detectors are so flexible and have so many uses, it offers feelings of protection and security for the average homeowner as well as commercial organizations [4]. An electronic motion detector is a device used to detect any physical movement in a given area and transforms motion into an electric signal.It consist of sensor that electrically connected to other devices such as security system, lighting, audio alarms, and other applications. Motion sensors are used in a wide variety of applications and as a result, many different types of motion sensors are available including the infrared sensor. Infrared sensors are widely known in the arts of intrusion detection and in fire or smoke detection. It is a device that often used in automatic light switches and security systems to turn on a light or to activate some other form of alarm or warning indicator when a person enters a monitored area [4].The infrared sensors have basically two forms: active and passive. [4] An active infrared detector includes a radiation source and an infrared sensor which is sensitive to interruptions in the radiation sensed from the source. [4] These detectors are used as intrusion detectors by providing a path of radiation from the source to the sensor in a place where the path is likely to be interrupted by an intruder. The proposed active infrared method of motion detection has the advantage of fast speed response of a relatively large sensor.This advantage permits simpler optical system design, especially for wide fields of view. Besides, it is insensitivity to mechanical and acoustic noise, which presents substantial problems in the passive infrared (PIR) sensors. Low production cost is another advantage of these active infrared detectors. [4] Passive infrared motion detection detects heat energy radiated or emitted by an object, such as a body of a person, moving across a field of view of a heat sensor of the motion detection system. It is generally use an optical ollection system and multiple sensing elements of alternating polarity to create a detection pattern in the volume of interest. PIR detectors employ a group of radiation sensors coupled through amplifiers to a logic circuit. The radiation sensors detect changes in ambient infrared radiation. The detection system has an electrical circuit operatively coupled to the heat sensor for producing a detection signal in response to the heat sensor detecting a change of temperature caused by the body heat of a person entering the detection pattern. PIR motion detectors are perhaps the most frequently used home security device. 4] Passive IR motion detectors are usually designed to provide an indication to an alarm panel in response to detecting IR that is indicative of motion of the object. The alarm panel is responsive to receipt of the breach indication to cause an alarm condition to occur. The other motion detector used in security system is an ultrasonic motion detector. It is commonly used for automatic door openers and security alarms [4]. It is inexpensive and can operate with narrow beam-widths. The ultrasonic transducers are the sensor that used in ultrasonic motion detector.It can be used to detect motion in an area where there are not supposed to be any moving objects. This type of motion detector is most commonly used in burglar alarm systems since they are very effective in this application [4]. In an ultrasonic motion detector, there are two transducers; one emits an ultrasonic wave and the other picks up reflections from the different objects in the area. The reflected waves arrive at the receiver in constant phase if none of the objects in the area are moving. If something moves, the received sig nal is shifted in phase. A phase comparator detects the shifted phase and sends a triggering pulse to the alarm.Ultrasonic motion detectors have certain advantages and disadvantages when compared with other types of motion detectors. The main advantage is that they are very sensitive and extremely fast acting. However, the largest problem with this type of motion detector is that it sometimes responds to normal environmental vibration that can be caused by a passing car or a plane overhead. Besides, the installation options on this type of motion detector are limited because ultrasonic beams are easily blocked by thin materials, including paper. False triggering is easily caused by reflections from blowing curtains, pets, and flying insects.While the passive infrared motion detectors offers problem where it can be falsely triggered by warm air movement or other disturbances that can alter the infrared radiation levels in an area. In order to prevent this problem, newer systems use t wo infrared sensors, which monitor different zones within a protected area. Logic within system triggers the alarm only when the two zones are activated in sequence, as would occur if a person walked through the protected area. For that reason, the purpose of using the active infrared as a sensor to detect motion for this project is surely on the advantage offers by the sensor.Its capability on detecting motion with a simple design at lowest cost is needed to build an effective house security system based on motion detection. 1. 5 Thesis outline Chapter 1 explains the background of motion detection, the project objective, the project scope, and the literature review of motion detector for security system. The concepts of motion detector are the major element as a guide for the development of the security system. Chapter 2 explains the systems involved for the development of the active infrared motion detector for house security system.The understanding of three systems which are the active infrared, motion detector, and house security system stated in this chapter needed for the development of the whole project. Chapter 3 focuses on the methodologies for the development of the electrical structure and the implementations of microcontroller programming. It gives a brief review on the concept of active infrared motion detector, the electrical structure for hardware development, and the programming for the operation of the security system. Chapter 4 discusses on the results obtained of the whole project.All discussions are concentrating on the result and performance of the security system. The discussion is valuable for future development of the security system. Chapter 5 discusses about the conclusion on development of the active infrared motion detector for house security system. The recommendations and modification required on this project is stated in this chapter for further development. CHAPTER 2 ACTIVE INFRARED MOTION DETECTOR FOR HOUSE SECURITY SYSTEM 2. 1 Introduction There are two systems on a development of the active infrared motion detector for house security system.The first system is an active infrared motion detector and the other one is the controller system. The first system concentrates on a development of an active infrared motion detector. It is consists of three element, which are the active infrared, the motion detector, and the house security system. The motion detector circuit will be control by the second system which is the microcontroller Intel 8051 based system. The combination between this two systems will built a project called an active infrared motion detector for house security system. 2. 2 Active infrared (IR)Infrared is an electromagnetic spectrum at a wavelength that is longer than visible light. It cannot be seen but it can be detected. Objects that generate heat also generate infrared radiation and those objects include animals and the human body whose radiation is strongest at a wavelength of 9. 4 µ meter. Infrared in this range will not pass through many types of material that pass visible light such as ordinary window glass and plastic. However it can pass through, with some attenuation, material that is opaque to visible light such as germanium and silicon. The active infrared sensors use invisible light to scan a defined area.In active infrared systems, there are two-piece elements which are consisting of an infrared transmitter and an infrared receiver. There is a 3/8 inch infrared beam between the transmitter which is placed on one side of the trail and the receiver which is placed on the other side of the trail. The transmitter and the receiver can be separated by as much as 150 feet. The transmitter emits a beam of light into the scan zone. The light, which is reflected by the background returns to the receiver, which constantly monitors the scan zone. When a person or object enters the zone the infrared light is interrupted.It then sends a signal to the controller sys tem, which is wired into the door controls. One variation of this operating mode is called ‘background suppression’. This is when the receiver only detects a change in the reflected light when a person or object enters the scan zone thus causing a reflectance variation of the light, sending a signal to the microcontroller thus trigger the alarm of the security system. 2. 3 Motion detector A motion detector is a device that contains a motion sensor and is either integrated with or connected to other devices that alert the user of the pre-sense of motion.An electronic motion detector contains a motion sensor that transforms the detection of motion into an electric signal. The electric signal can be connected to a burglar alarm system which is used to alert the home owner or security service after it detects motion. An example of sensor that used in security system is an active sensor. Active sensors in motion detectors system are commonly used inside homes for a security system. An active motion detector emits optics or sound waves and measures feedback to detect motion. The simplest type of active motion detector is commonly used in commercial doorways to trigger a doorbell.A device is fixed to one side of the doorway, an optical sensor to the other. A beam of light will passes from the device through the sensor. When someone enters the establishment, the beam is broken, triggering the doorbell thus warn user for the intrusion. For that reason, active motion detectors can be purchased for home improvement security system. It is inexpensive devices that can add for more security to a home and provide peace of mind for home owners. 2. 4 House security system House security system is one of security that truly related to burglar or safety alarm system.Burglar and safety alarms are found in electronic form nowadays. Sensors are connected to a control unit via either a low-voltage hardwire which in turn connects to a means for announcing the alarm to el icit response. In a new construction systems are predominately hardwired for economy while in retrofits wireless systems may be more economical and certainly quicker to install. Some systems are dedicated to one mission; handle fire, intrusion, and safety alarms simultaneously. In common security system, the lights are triggered by motion gives the impression to user that someone is at home and able to see the burglar.Infrared motion detectors placed in house security system in crucial areas of the house can detect any burglars and alert the home owner or police. The first security system invented, house alarms were triggered by the release of a pressure button fitted into a door or window frame. This basic alarm was fundamentally flawed as the entire intruder needed to do to silence the alarm was to close the door or window. While various systems on the market ranging from inexpensive house security alarms to highly sophisticated systems requiring professional installation.All mode rn alarms are based on the same foundation, the electric circuit which is completed either when the door is opened or closed depending on the security system designed. The alarm is triggered when the circuit is altered and will not be silenced until a code is punched into the control panel. The most expensive and complicated alarm systems might also involve a combination of motion sensors and pressure pads to ensure even the most cunning intruder doesn’t get his hands on treasures. 2. 5 Microcontroller Intel 8051 The microcontroller 8051 is an 8-bit machine.Its memory is organized in bytes and practically all its instruction deal with byte quantities. It uses an Accumulator as the primary register for instruction results. Other operands can be accessed using one of the four different addressing modes available: register implicit, direct, indirect or immediate. Operands reside in one of the five memory spaces of the 8051. The five memory spaces of the 8051 are the Program Memo ry, External Data Memory, Internal Data Memory, Special Function Registers and Bit Memory. The Program Memory space contains all the instructions, immediate data and constant tables and strings.It is principally addressed by the 16-bit Program Counter (PC), but it can also be accessed by a few instructions using the 16-bit Data Pointer (DPTR). The maximum size of the Program Memory space is 64K bytes. The External Data Memory space contains all the variables, buffers and data structures that can not fit on-chip. It is principally addressed by the 16-bit Data Pointer (DPTR), although the first two general purposes register R0 and R1 of the currently selected register bank can access a 256-byte bank of External Data Memory. The maximum size of the External Data Memory space is 64K bytes.The external data memory can only be accessed using the indirect addressing mode with the DPTR, R0 or R1. The Internal Data Memory space is functionally the most important data memory space. In it resi des up to four banks of general purpose registers, the program stack, 128 bits of the 256-bit memory, and all the variables and data structures that are operated on directly by the program. The maximum size of the Internal Data Memory space is 256-bytes. The register, indirect and direct addressing modes can be used in different parts of the Internal Data Memory space.The Special Function Register space contains all the on-chip peripheral input and output registers as well as particular registers that need program access. The maximum number of Special Function Registers (SFRs) is 128, though the actual number on an 8051 family member depends on the number and type of peripheral functions integrated on. The SFRs can only be accessed using the direct addressing mode while the upper 128 bytes of the Internal Data Memory can only be accessed using the Indirect addressing mode. The Bit Memory space is used for storing bit variables and flags.There are specific instructions in the 8051 th at operate only in the Bit Memory space. The maximum size of the Bit Memory space is 256-bits. Bits can only be accessed using the bit instructions and the direct addressing mode. 2. 6 Summary The understanding on the elements of the systems involved for this project which are the active infrared, the motion detector, and the house security system is needed before proceed for the design and development process. This is important to ensure the project done according to the main idea of each part discuss in this chapter. CHAPTER 3 METHODOLOGY 3. 1 IntroductionThere are several steps to be applied in designing an active infrared motion detector for house security system. The relevant information is gathered through literature review from previous chapter. Data on motion detection and security system projects has been collected where the theoretical design is studied based on the motion detector for security concept. The understanding on the electrical structure for the hardware develop ment is needed for the design circuit process of the motion detector and the basic security circuit. The next is the hardware development according to the circuit designed.This process is just only being proceed if each part of the circuit being improved is valid, else, it will be repeated until it is valid as the theoretical. Once the hardware development circuits have the output as the expected, then, the comparison for both hardware and theoretical analysis will be done. Next is the step where software structure is developed for the security system to be interface with the hardware development. While the final step of this research is on applying the whole project to the real house entrance like doors and windows. 3. 2 The concept of motion detector for security systemFigure 3. 1 Active infrared motion detectors Figure 3. 2 shows the concept of an active infrared motion detector for a security system. In the active system each sensor consists of two housings. The first housing co ntains an infrared-emitting diode and an infrared-sensitive phototransistor as the infrared detector. The other housing contains an infrared reflector to reflect the infrared signal. When positioned in front of an entrance to a protected area, the two housings establish an invisible beam. Figure 3. 2 The concept of infrared motion detector for security systemA person who enters the area will interrupts the beam causing an alarm to be triggered. For this type of motion detector uses the basic concept of the active infrared motion detector. An interruption in the signal modulated pulsating beam transmit by an infrared diode while receive by an infrared detector will set ‘on’ or ‘off’ the alarm of the security system. 3. 3 Hardware development Figure 3. 3 Block diagram for the house security system The hardware development is divided into three stages as shown in block diagram above. The inputs stage of the security system is the motion detector circuit, keypa d, and magnetic sensor.The second stage is the controller unit which is the microcontroller Intel 8051. The purpose of using microcontroller is to control the whole system operation by sending data to the output stage which is the LCD display, indicator, and buzzers. 3. 3. 1 Motion detector circuit In designing the infrared motion detector circuit, it is based on two basic principle of active infrared motion detector which is the infrared transmitter and infrared receiver as shown in Figure 3. 4. Figure 3. 4 Basic principle of infrared operation 3. 3. 2 Infrared transmitterFor the infrared transmitter which is also known as emitter circuit, it is on a basic design of timer 555 astable operation. The output of timer is connected to the infrared transmitter is used to produce pulse using an astable timer circuit. In astable circuit operation, pulse will continually generated until the power supplied through the circuit is removed. The astable circuit produces a continuous train of pul ses at any frequency required. This means that the 555 timer can operate repeatedly; it will switch ‘on’ and ‘off’ continually to generate data for the infrared transmission. . 3. 3 Infrared receiver The infrared receiver which is also known as infrared detector receives the data transmitted by the infrared transmitter circuit. It is a simple electronics device on detecting infrared signal. This infrared detector can be directly connected into the controller circuit to produce logic high ‘1’ or low ‘0’ from the output terminal thus activate or deactivate the controller system operation. The range of infrared detector components according to datasheet stated that the infrared detector can fully operates on detecting the infrared signal of 38 to 45 kHz. . 3. 4 4 ? 4 hexadecimal keypad The purpose of using 4 ? 4 hexadecimal keypad in the project is as an input where secure code entries to activate of deactivate the security system ope ration. The keypad provides eight interface pins, where one pin for each row and column of the keypad matrix. This 4 ? 4 hexadecimal keypad is connected to the keypad encoder (MM74C922) to control the keypad bouncing in the hardware development. 3. 3. 5 Keypad encoder (MM74C922) The MM74C922 key encoders provide all the necessary logic to fully encode an array of 4 ? hexadecimal keypad. It is used to encode the data received from the keypad code entry thus convert into binary code. These binary code is in hexadecimal number is required in data bus of the microcontroller system. Figure 3. 5 Interaction between keypad, keypad encoder, and octal buffer The figure 3. 5 above shows the block diagram on the interaction between the 4 ? 4 hexadecimal keypad, keypad encoder (MM74C922), and the octal buffer (74LS244). The keypad is used as a switch to give logic configuration to the keypad encoder.While the encoder will encode the data configuration from the keypad into the binary code based on datasheet of the encoder. These binary codes will be stabilized using the octal buffer to be process in the microcontroller system. These data will be process by the microcontroller thus running the system operation based on software designed for the security system. 3. 3. 6 Octal buffer (74LS244) A buffer is simply a unity-gain amplifier, usually with very high input impedance and very low output impedance. It allows a connection of heavily loaded to another load which requires a lot of current like capacitive load.The octal buffer is used to isolate one device from another by eliminating loading effects. It provides a ‘buffer’ between the two devices. The 74LS244 are octal buffers and line drivers designed to be employed as the memory address drivers, clock drivers, and bus-oriented transmitters/ receivers which provide improvement on the controller board density. 3. 3. 7 Microcontroller circuit (Intel 8051 – expended mode) The controller systems that use to control the motion detector system and other electronic devices are the microcontroller Intel 8051 – expended mode.In expended mode configuration, external ROM and RAM are used to add the data memory to be more than internal memory provided by the Intel manufacturer. The purpose of using an expended mode for the project is to expend more data available on developing and designing an excellent operation of the security system. Figure 3. 6 Intel 8051 block diagram The microcontroller Intel 8051 is a widely used on controlling devices and instruments due to its flexibility, existence of multiple producers. It consists of a simple architecture introduced by Intel in the year of 80’s.It produced with 128 bytes of RAM, 4K bytes of on-chip ROM, 2 timers, one serial port, and 8-bits wide of ports. This type of microcontroller become very popular after Intel allowed another manufacturer to make and market any flavor of the 8051, and still remains compatible with 8051. There ar e various versions of 8051 with different speeds and amount of the on-chip ROM which is valuable on controlling a system designed. 3. 4 Software development The software structure is using the assembly language where a set of program based on security system is assembled using ASM51 assembler.The 8051 Cross Assembler (ASM51) takes an assembly language source file created with a text editor and translates it into a machine language object file. This translation process is done in two passes over the source file. During the first pass, the Cross Assembler builds a symbol table and labels that used in the source file. While the second pass of the Cross Assembler is actually translates the source file into the machine language object file. During the second pass, the listing file of the assembled is generated for the analysis purpose.A security program as shown in flow chart below were written in notepad based on 8051 instruction set before assembling process to get the binary code. Thi s binary code is then used to be load into the location of the memory thus operates the hardware developed. The flowchart as shown in Figure 3. 7 is a basic designed for the security system operation. In this security system, the security code is set as ‘1985’ to activate or deactivate security system. When user closed the door, the system will activate where the magnetic switch and infrared is in active condition.To deactivate the system where opening door without alarm, user must enter the deactivation code. The chance to deactivate the system is once before keypad locked, where user can not enter the code anymore. If deactivation code was correct, green LED will ‘on’ while alarm will ‘off’ condition. System at this time is successfully deactivated and user can open the door without alarm. Figure 3. 7 Flow chart of software design for the security system If deactivation code enters was incorrect, system is still activate and for that, red LED and alarm will ‘on’ where the system is in a warning mode.The system will keep in this mode until the correct deactivation code entered. When the correct deactivation codes enter, the reconfirm code is needed where user need to reenter the correct deactivation code before the system successfully deactivate; the green LED will ‘on’ and the alarm will ‘off’ condition. The reconfirm code is designed in the system to make more security for the system developed. If intruder open the magnetic switch without entered the correct security code, thus the alarm will ‘on’. User must enter the correct deactivation code to turn ‘off’ the alarm system.The activation and deactivate code for this system are ‘1985’ and the ‘enter’ button codes are ‘A’ for every codes entered. 3. 5 Summary There are three elements discussed in this chapter which are the concept of motion detector for security syste m, the hardware development, and the software designed for the security system. Each part of these elements is related to each other. The understanding of the concepts and methods on developing the project is very important to achieve the main objective for the whole project. CHAPTER 4 RESULTS AND DISCUSSIONS 4. 1 IntroductionThis chapter will briefly discuss on the results and discussions of the hardware development. There are three major modules in developing the hardware structure which are the active infrared motion detector circuit, keypad module circuit, and the most important; the controller circuit 4. 2 Motion detector circuit The hardware development of the active infrared motion detector system is divided into two parts, which are the infrared emitter circuit and the infrared detector component. 4. 2. 1 The emitter The emitter which also known as infrared transmitter circuit was build as shown in Figure 4. . A probe or the oscilloscope is attached to the infrared LED while the adjustable resistor is varied to calibrate the emitter to transmit 38 kHz square wave. The Figure 4. 1 shows the final configuration of the emitter circuit: Figure 4. 1 The emitter circuit Figure 4. 2 shows the result obtained from the oscilloscope where the frequency generated by the emitter circuit is 38. 67 kHz square wave. At this generated frequency, the voltage maximum produced is 1. 60V and the peak to peak voltage is 1. 16V. Figure 4. 2 The 38 kHz frequency generated by the emitter circuit

Dogs Make Good Companions

Dogs make good companions, because of the loyalty, unconditional love, friendship, and protection they give. When you wake up in the morning they don’t care if you have morning breathe, bed head, and no make-up, after a long day stressful day, door to that tail-wagging ready to give you hugs and kisses because your home. It makes all You’re worries and stresses go right out the door. For instance, they will always show unconditional love and loyalty. You might feel emotional, angry, or even talking out loud to yourself about your horrible day, who is there?Your dog, listening wagging its tail. They will never be judgmental, they don’t care about what name brand clothes you’re wearing, the car you drive, the house you live in, they will love you for you. If your late feeding them, or you raised your voice because they did something wrong, they won’t complain and will always forgive you. On a cold winter night they will be right there to be your snugg le buddy and keep you warm. Another instance dogs can be good protectors of their family/owner and home.Next time You’re out on a walk or in the park with family and friends watch the reactions of dogs. If a person or animal are getting a little too close they will get that alert look, eyes wide open, ears at attention, watching the surroundings. When they feel a possible threat, they get that vicious look, curled lips, fangs all out and making brutish noises through their nose, making sure, that person or animal knows they mean business when it comes to protecting Family/owner. When it comes to protecting their home, they will go to great lengths, even giving their life.Do some research on how many dogs have saved their family from burglars, fires, Carbon Monoxide Statistics show that owners are less likely to be burglarized than non- dog owners are. Dogs bark to alert, letting you know something is not wrong and for you to go investigate. Did you know dogs are also good for your health? Just petting or cuddling with your dog can Relieve stress, lower blood pressure, and lower your heart rate. Taking your dog for a walk provide them the exercise, but you’re also getting some cardio exercise in as well. Dogs sense when you’re not feeling well, staying by your side comforting you the best way they now how. When you’re emotionally drained or depressed, they are right there showing you love and support, letting you know it’s going to be all right, and they are there for you for matter what. Dogs enjoy making you smile, which is good for the soul. One final thought is dogs don’t ask for much for the unconditional love, friendship, loyalty. Dogs are willing to give their life to protect their family. Dogs need very little care for the companionship they give you in return. Sure, they need food, water, and basic care just like you, but all they want is love, attention, and affection.Rather, it’s playing fetch, going f or a walk, for a ride, or cuddling on the couch, doing little things, makes the companionship stronger. Just like any other friendship in your life, you have to make time and make it work. Now ask yourself a couple of questions. Do you have friends that give unconditional love? Do you have any friends there for you 24/7? Do you have friends that want to be around you when you’re emotional, angry, and stressed? Are friends their when you’re feeling sick? Dogs just may be the true friend and companion you never had. That’s why dogs make good companions.

Islams Role In The Development Of Science Religion Essay Example

Islams Role In The Development Of Science Religion Essay Example Islams Role In The Development Of Science Religion Essay Islams Role In The Development Of Science Religion Essay The most common misconception about Islam is the thought that the faith inspires retardation ; Muslims are believed to be opposed to modernness, comparing it with foul and iniquitous ways. This misconception, nevertheless, stems largely from the misinterpretation between Western and Islamic civilizations. The West, sing itself as the prototype of modernness, assumes that Muslims knocking Western orgy must be opposed to come on itself. In world, nevertheless, the reaching of Islam signalled a important transmutation in the Middle Eastern part. The Prophet Muhammad s instructions served as the accelerator for noteworthy developments in the part, peculiarly in the Fieldss of scientific discipline, jurisprudence and literature. This paper posits that Islam plays a important function in the development of scientific discipline, jurisprudence and literature in the Middle East. To turn out so, this paper shall get down with a brief background of Islam to function as the foundation of the survey. The survey shall non dig into inside informations of cabals in the faith, given the restraint and focal point of the paper. The survey shall so look into the parts of Islam to three specific facets of Middle Eastern development, viz. scientific discipline, jurisprudence and literature. Surely, Islam s parts are non limited to these three countries, but they are important adequate to reflect the overall impact of the faith on the part. Muslimism: A Brief Review Prophet Muhammad was a shepherd and bargainer who sought consolation from speculation. He frequently retreated to the caves environing Mecca for personal contemplation, and it was in one of these caves that he received the disclosure of Allah. Islam is the complete resignation of a individual to the will of God, and Muhammad began to prophesy his new faith to the folks of Mecca. He was met with ill will and derision and was forced to fly to Medina. Slowly, Muhammad began to garner followings and protagonists, finally suppressing Mecca and engaging a campaign to change over the folk of the Middle East. The disclosures of Allah to Muhammad are recorded in the Quran, the Muslim sanctum book. Like Judaism and Christianity, Islam is monotheistic. More significantly, Islam really recognises cardinal figures from these faiths, claiming that Abraham, Moses and even Jesus were besides Prophetss of Allah. Muhammad, nevertheless, was the last prophesier and Islam is hence the right faith. Interestingly, these three faiths portion pilgrims journey shrines and noteworthy characteristics but are frequently at odds, largely as a consequence of political relations more than anything else. Due to his finding and turning figure of protagonists, by the clip of Muhammad s decease, his mission to change over the Arabian Peninsula had mostly succeeded. Islam and Science Science is unfailingly equated with modernness. Even in the United States, the thought of scientific discipline holding with faith is hard to grok ; conservative positions frequently times clash with scientific discipline due to its irreverence towards the dictates of religion. How so, could a faith such as Islam ( which, as mentioned earlier, is equated with immovable antiquity ) have fostered the development of modern scientific discipline in the Middle East? It must be understood that Islam is non simply a faith to its followings ; it is the guideline for all countries of life and idea. As such, even the development of cognition is linked to the apprehension that nature is an extension of Allah, and cognizing Allah means exercising attempt to cognize more about the natural universe ( Iqbal 2007 p.10 ) . As such, Islam gave rise to a batch of scientists both Arab and non-Arab chiefly because of its accent on the accretion of cognition. Some noteworthy scientists include Ibn Alhazen, male parent of the scientific method ( precursor to empiricist philosophy ) ; Ibn al-Shatir posited the Maragha Theory that predated Copernicus lunar theoretical account, and ; al-Kwarizmi criticised the Ptolemic theoretical account by observing its failings right ( Iqbal 2007 ) . Apart from these single accomplishments, Islamic swayers supported the development of surveies in uranology, mathematics and natural philosophies, supplying the foundation that allowed these scientists to set forward their theories and contribute to the development of scientific cognition. Islam and Law The Shariah is Islamic jurisprudence the Muslims keep it sacred and it remains one of the most outstanding legal systems in the universe today. It is non that the Middle East did non hold any signifier of legal system prior to Islam. What is important, nevertheless, is that Islam brought about interesting and modern alterations to the Torahs that were present in the folk of the Middle East. For illustration, prior to Islam, the jurisprudence dictated that hubbies could disassociate their married womans instantly. The adult male had the concluding say in this affair, and the adult female was merely left to bear the brunt of the terminal of a bad matrimony. With the debut of the Sharia, the values that were of import to Islam became important in jurisprudence every bit good. With the Sharia, a adult male would now hold to wait for three months ( or until childbirth, if the adult female was pregnant ) before divorce could be finalised. This was a agency to deter divorce and let the twosome to accommodate during the period ( Hallaq 2005 p.23 ) . Besides, the jurisprudence was unprecedented in that it introduced the fiscal independency of adult females, leting them to retain their doweries as personal belongings. Furthermore, they were allowed to hold all belongings she personally acquired during matrimony to stay entirely her belongings, without holding to postpone to her hubby ( Hallaq 2005 p.23 ) . These are some illustrations of Islam impacting the jurisprudence. Islam and Literature Of the three facets mentioned in this paper, this country is the most apprehensible in the sense that faith frequently inspires poesies, peculiarly due to the ecstatic nature of the faithful. Once inspired, a poet could compose heroic poems in congratulations of his God, and therefore the fact that Islam had a important impact on the development of literature comes as no daze. Apart from the development of verse forms and wordss, nevertheless, Islam besides contributed greatly to the constitution of the hero tradition in Middle Eastern literature ( Renard 1999 p.43 ) . This includes romantic and/or royal heroes, every bit good as spiritual 1s. Some illustrations include the publicity of the Bedouin ideal, transformed from its original mobile warrior into a spiritual theoretical account. This, nevertheless, does non intend that the common people qualities of the hero are sacrificed merely to carry through the purpose of the author ( which may be misconstrued as some signifier of spiritual white-washing of folklore ) . For illustration, the common people hero Miqdad is a well-known Bedouin character. His ulterior portraitures include his defense mechanism of the Islamic religion every bit good as exhibits values in support of Islamic jurisprudence, but without decreasing his character as a fierce and fearless Bedouin. As Renard ( 1999 p.47 ) points out, the Islamic impact on literature enhanced folklore, non submerged it. It is besides noteworthy that Islam brought about the debut of a new sort of genre having spiritual heroes. One really good illustration is Muhammad himself. The narratives of his escapades through the universe and beyond uncover a new sort of heroic poem. It was a combination of literature and religious instruction, chronicling Muhammad s instructions and uniting them with fiction in order to make an piquant narrative. The Miqyarat , for illustration, chronicles Muhammad s journey into enlightenment and find ( Renard 1999 p.105 ) . This is one of the interesting developments in Middle Eastern literature that would non hold occurred if non for Islam. Decision Having discussed the following countries of development that were impacted greatly by Islam, it is now safe to reason that Islam plays a important function in the development of scientific discipline, jurisprudence and literature in the Middle East. What so is the significance of this decision? As mentioned earlier, Islam is one of the most misunderstood faiths in the universe at present. What is known of Islam is the debauched version peddled by political operators, seeking to use the faith to incorporate the multitudes. The wrong reading of jehad , for illustration, by terrorist administrations delivers a really negative message about Islam. Hopefully, through this paper, a more positive apprehension of Islam and Muslims shall go possible.

Iguana Facts

Iguana Facts There are over 30 species of iguanas which belong to the class Reptilia. Depending on the species, iguanas’ habitats range from swamps and lowlands to deserts and rainforests. Iguanas are organized into nine broader categories of species: the Galapagos marine iguanas, Fiji iguanas, Galapagos land iguanas, thorntail iguanas, spiny-tailed iguanas, rock iguanas, desert iguanas, green iguanas, and chuckwallas. Fast Facts Scientific Name: IguanidaeCommon Names: Common Iguana (for green iguana)Order: SquamataBasic Animal Group: ReptileSize: Up to 5 to 7 feet (green iguana) and as small as 5 to 39 inches (spiny-tailed iguana)Weight: Up to 30 pounds (blue iguana)Life Span: 4 to 40 years on average depending on speciesDiet: Fruits, flowers, leaves, insects, and snailsHabitat: Rainforests, lowlands, swamps, desertsPopulation: A small number of individuals to several hundred per hectare (green iguana)Conservation Status: Least Concern (green iguana), Endangered (Fiji iguanas), Critically Endangered (Fiji crested iguana)Fun Fact: Marine iguanas are excellent swimmers. Description Iguanas are cold-blooded, egg-laying animals and are some of the largest lizards found in the Americas. Their size, color, behavior, and unique adaptations vary depending on the species. Some, like the Fiji banded iguana, are bright green with white or light blue bands while others have dull colors.  Marine iguanas have black coloration to help warm their bodies after swimming in cold ocean waters. Iguana on a rock. Shikhei Goh / Getty Images The most abundant and well-known type of iguana is the green iguana (Iguana iguana). Their average size is 6.6 feet, and they weigh up to 11 pounds. Their green color helps camouflage them in undergrowth, and they have a row of spines on their body which function as defense. Habitat and Distribution Depending on the species, iguanas live in a variety of habitats including deserts, rocky regions, swamps, rainforests, and lowlands. Green iguanas are found throughout Mexico down to Central America, the Caribbean Islands, and southern Brazil. The iguana species inhabiting the Caribbean islands are collectively known as the rock iguanas. Desert iguanas are found in the southwestern U.S. and Mexico, while two genera of marine iguanas inhabit the Galapagos Islands. Diet and Behavior Most iguana species are herbivores, eating young leaves, fruits, and flowers. Some eat insects like the wax worm, while marine iguanas dive into the ocean to harvest algae from plants. Some species house bacteria in their digestive systems which allow them to ferment the plant material they eat. Green iguanas are omnivores when they are young but shift to almost entirely herbivorous diets as adults. Young green iguanas eat mostly insects and snails and shift to eating fruits, flowers, and leaves as adults. They have sharp teeth that allow them to shred leaves. Green iguanas also live high in the tree canopy and inhabit higher altitudes as they grow older. Another interesting fact about iguanas is that they can detach their tails when in danger and regrow them later. Fiji crested iguana (Brachylophus vitiensis) on Viti Levu Island, Fiji. It is critically endangered species of iguana found on some Fijian islands. Donyanedomam / Getty Images Reproduction and Offspring Iguanas generally reach the age of sexual maturity at 2 to 3 years and can lay anywhere from 5 to 40 eggs per clutch depending on the species. For green iguanas, males establish mating pairs with females during the rainy season and leave the tree tops to fertilize the eggs during the beginning of the dry season. Most iguana species dig a burrow in sunny areas to lay their eggs inside and cover them. The ideal temperature range for incubation of these eggs is between 77 to 89 degrees Fahrenheit. After 65 to 115 days, depending on the species, these young hatch at the same time. After digging out of their burrows, the newly hatched iguanas begin their lives on their own. Species Marine iguana feeding on an algae covered rock. Wildestanimal / Getty Images There are roughly 35 living species of iguanas. The most abundant species is the Common or Green iguana (Iguana iguana). Iguanas are grouped into 9 categories based on their habitats and adaptations: the Galapagos marine iguanas, Fiji iguanas, Galapagos land iguanas, thorntail iguanas, spiny-tailed iguanas, rock iguanas, desert iguanas, green iguanas, and chuckwallas. Threats The Fiji iguanas are an endangered species, with the Fiji crested iguana listed as critically endangered. The biggest factor in the decreasing numbers of Fiji iguanas are predation by feral cats (Felis catus) and the black rat (Rattus rattus) invasive species. Additionally, crested iguanas are critically endangered due to the rapid decrease in their habitat of dry healthy forests in the Fiji Islands. This habitat reduction is due to clearing, burning, and conversion of forests to farmlands. Conservation Status The green iguana is designated as least concern according to the International Union for Conservation of Nature (IUCN). All species of the Fiji iguanas group are designated as endangered according to the IUCN, with the Fiji crested iguana (Brachylophus vitiensis) listed as critically endangered. Iguanas and Humans Green iguanas are the most common reptile pets in the U.S. However, because they are hard to care for, many of these pets die within the first year. In Central and South America, green iguanas are bred on farms and eaten by people. Their eggs are considered a delicacy, often referred to as the â€Å"chicken of the tree.† Sources Green Iguana.

Norman Rockwells Painting Essay Example | Topics and Well Written Essays - 500 words

Norman Rockwells Painting - Essay Example This article states that the painting was inspired by Rockwell’s when he visited the Soviet Union. The painting offers a learning experience for teachers, students, and adult learners. The artist had an insightful observation of Russian classroom experience of schoolchildren in the 1960s. The artist was reflecting what he observed during his visit and was amused with what he saw. This made him to reflect but and inspire other students in both upper and lower primary. It was also an inspiration to parents and teachers on the extent to which children can stay focused on their own. The author believes that the problem we all live with has been embraced and become an important symbol of civil rights. It acts as a remembrance of the day when the United States Supreme Court declared the racial segregation unconstitutional. The painting bears a black girl who is determined to go to school and she is under escort. Additionally, the author asserts that the painting is a symbol of victo ry on the black race following the court verdict that state law establishing separate public schools for whites and blacks were unconstitutional. The artist was quick to take note because he was a supporter of tolerance and equality. The author outlines that the federal Supreme Court declared segregation illegal in public schools. Norman Rockwell drew the picture to show a young black girl in a uniform walking to school in little rock. The child is protected by US federal marshals, something which has never been realised.

Social Inequality Essay Example | Topics and Well Written Essays - 1000 words

Social Inequality - Essay Example Although the country has gone a long way toward an appearance of classlessness, class is still the prevailing force determining the way people are distinguished in the contemporary America. As Janny Scott and David Leonhardt maintain, "class is still a powerful force in American life. Over the past three decades, it has come to play a greater, not lesser, role in important ways. At a time when education matters more than ever, success in school remains linked tightly to class. At a time when the country is increasingly integrated racially, the rich are isolating themselves more and more. At a time of extraordinary advances in medicine, class differences in health and lifespan are wide and appear to be widening." (Scott and Leonhardt) Therefore, there are several evidences from education sector, health industry, and financial sector which prove the increasing influence of class in American life. Social inequality in health sector provides one of the most important evidences for the escalating influence of class in American life. ... Miele's, Mr. Wilson's and Ms. Gora's (people belonging to different classes) struggles to recover. "Class is a potent force in health and longevity in the United States. The more education and income people have, the less likely they are to have and die of heart disease, strokes, diabetes and many types of cancer. Upper-middle-class Americans live longer and in better health than middle-class Americans, who live longer and better than those at the bottom." (Scott) According to the scholars who have researched social factors in health the gaps among the various classes are widening. In their attempt to support the claim that class matters in American life, the New York Times Correspondents provide examples from marriages that cross class boundaries. Although these challenges are not as obvious as those that cross the lines of race or nationality, "people who marry across class lines are also moving outside their comfort zones, into the uncharted territory of partners with a different level of wealth and education, and often, a different set of assumptions about things like manners, food, child-rearing, gift-giving and how to spend vacations. In cross-class marriages, one partner will usually have more money, more options and, almost inevitably, more power in the relationship." (Lewin) According to the New York Times Correspondents, evidences from religious practices also suggest that class matters in American life and the growing power and influence of evangelical Christians illustrates this social inequality. "Their growing wealth and education help explain the new influence of evangelicals in American culture and politics. Their buying power fuels the booming market for Christian books, music

We don’t offer advisories about subject matter, as sensitivities vary from person to person. If you have any concerns about content, please contact the box office. Mona Golabek doesn't just tell a great story. Seated at a concert grand, she accompanies her tale with music that infuses, illustrates, amplifies and elevates "The Pianist of Willesden Lane" to make the personal universal and another generation so personal that you can't help but feel your heart swell in response. Great music can do that. Skillfully blended with an affecting tale, it can do even more.

Research paper over a specific theme portrayed in the sotry Essay

Research paper over a specific theme portrayed in the sotry - Essay Example The involvement in the scenes becomes more and more thorough, and the collective partakers become a social group where in the person experiences identity problems. At first, the unison of the collective is embodied through the expression ‘we all’; afterwards this unison assumes a virtually individual character (Holland 2001). The collective retreats and the centralized responses are disrupted merely when it is stated about Emily that â€Å"she carried her head high† (Holland 2001, 29). The expression...... At the onset the group of partakers of the narrator appears to be distinguished by the collective ‘first person (I)’ because it emerges beside ‘older people’, ‘the ladies’, and ‘people’ (Staton 1987, 88). Afterwards the sentiments and ideas of the ‘we’ circle quite totally mix with those of another group that the notion of a bigger group surfaces, a united group which involves majority of the town folks. At a different scene the entirety of the town, initially called as ‘our’ is evidently denoted as ‘we’. The individually feeble ‘our town,’ which gives the storyteller some extent of detachment from the group, opens up the ‘our’ which permits the storyteller to unite completely with the group (Kirszner & Mandell 1994): â€Å"The day after his death all the ladies prepared to call at the house and offer condolence and aid, as is our custom† (Kirszner & & Mandell 1 994, 78). The involvement in the scenes becomes more and more thorough, and the collective partakers become a social group where in the person experiences identity problems. At first, the unison of the collective is embodied through the expression ‘we all’; afterwards this unison assumes a virtually individual character (Holland 2001). The collective retreats and the centralized responses are disrupted merely when it is stated about Emily that â€Å"she carried her head high† (Holland 2001, 29). The expression ‘some ladies’ function separately, so as to provide supplementary thrust to the event. From then on the communal ‘first person’ once more emerges; the common purpose is hence enhanced and acquires more focus. Soon after the town government, which

International Entertainers Essay Example for Free

International Entertainers Essay The salaries of many singers, dancers and sports people have increased out of all proportion in recent years, while in places like Sudan people are starving to death. I do not beleive that anyone should be able to earn such enormous salaries whan so many people in the world are living in poverty. One af the factors which should affect what a person can earn ought to be the benefit of persons work to society. It is unreasonable for a famous singer to be able to earn far more from an evenings entertainment than, for instance, a medical scientist who develops a new drug which produces a treatment for a common disease. The pop star certainly has a value in society, but the value in no way exceeds, or even matches, the value gained from a successful medication. Secondly. work done should be paid according to the amount of effort and skill that goes into it. Nobody would deny that a famous person works hard and is skillful, yet such people do not work any harder than thousand of other workers who have no claim to fame. Yet market force are such that these superstarts can obtain millions of dolor while other unknown people sometimes earn less than they need to survive. Finally, it should be possible for governments to work together to ensure that the amount of money in circulation should be more more equally and fairly distributed. This seems only fair given that there are so many suffering. To conclude, it is clear that world poverty is a serious problem and yet the problem could be eased if governments and compenies gave more thought to paying salaries on a more equitable basis and if they started to contribute more money to those in need.

Experiment On Aqueous Solutions Solution Stoichiometry Biology Essay

Experiment On Aqueous Solutions Solution Stoichiometry Biology Essay The purpose of this experiment was to study the behavior of electrolytes and non-electrolytes through measuring the conductivity of different solutions. The experiment was divided into two parts. In the first part, the conductivities of seven different solutions were examined. Those solutions were HCl, CH3COOH, NaCl, CaCl2, CH3OH, distilled water and tap water. It was concluded that HCl, NaCl, and CaCl2 were strong electrolytes as they dissociate completely forming free ions. On the other hand, CH3COOH, CH3OH, and the tap water were weak electrolytes. This is because they partially dissociated into ions. Finally, the distilled water was found to be a non-electrolyte. In the second part of the experiment, the concentration of the Ba(OH)2 was determined by a titration process, when reacting with H2SO4 solution. The titration process was held by monitoring the conductivity of the base solution Ba(OH)2 throughout the reaction. This monitoring happened by changing the volume of the strong acid H2SO4 until the equivalence point was reached. Then calculations were done to find the concentration of Ba(OH)2 throughout the reaction, which was found to be 0.1 moles/L. The results of this experiment helps in understanding what types of species are present in different solutions and the strength of conductivities for different types of solutions. Such an experiment is very significant in the field of electricity, as the properties of strong and weak electrolytes play an important because they are considered to the basic components in many industrial products. Results Part (A) In this part of the experiment, the conductivity of different solutions was examined. Those solutions were NaCl, CaCl2 , CH3COOH, HCl, CH3OH, distilled H2O, and tap H2O. All of the solutions were of 0.1molarity. The following table shows the conductivity values collected. Table 1: Conductivity Values of Different Solutions Solutions Conductivity ( ¿Ã‚ ½S/cm) NaCl 13373 CaCl2 16923 CH3COOH 775 HCl 35765 CH3OH 207 Distilled H2O 198 Tap H2O 205 From the results found, it was concluded that the solutions tested varied in conductivity strength. For example, NaCl, CaCl2, and HCl ¿Ã‚ ½s conductivity values were relatively high compared with the other solutions. This clearly implies that they are strong electrolytes. Those three solutions were found to be strong electrolytes because the atoms of each molecule completely dissociated into positive and negative ions inside the aqueous solution, leaving no remaining reactant molecules. Therefore, those ions became free to conduct electricity. The following chemical equations illustrate the dissociation of those three solutions. HCl ? H+ + Cl- Eq(1) NaCl ? Na+ + Cl- Eq(2) CaCl2 ? Ca+ + 2Cl- Eq(3) On the other hand, it was observed that CH3COOH, CH3OH, and the tap water H2O were weak electrolytes because their conductivity was increased, but in a low rate. This happens to be a fact because those three solutions partially dissociated. This means that the atoms of those molecules formed ions, but to a limited extent, as some of those ions got attracted again to form the same molecule. Therefore, only the remaining ions in the solution conducted electricity. The following chemical equations show the reactions of those solutions. The arrow directed to the reactant indicates the reaction of the ions after the  ¿Ã‚ ½partial ¿Ã‚ ½ dissociation. CH3COOH H+ + CH3COO- Eq(4) CH3OH CH3+ + OH Eq(5) H2O H+ + OH- Eq(6) Finally, the distilled Water was found to be a non-electrolyte as the conductivity value was 198, which means that the distilled water had a very poor conductivity power. Therefore, it did not dissociate. As a result, no equation is to be illustrated. Part (B) In this part of the experiment, the concentration of the solution Ba(OH)2 was to be found through titrating it by adding 0.08 M H2SO4 . Various conductivity values were taken by adding few milliliters of H2SO4 into the solution. The table below lists the values of the added H2SO4 and the corresponding conductivity values of Ba(OH)2 solution of every addition. Table 2: The Conductivity of the Solution Ba(OH)2 as H2SO4 is Added. Volume (mL) Conductivity ( ¿Ã‚ ½S/cm) 1.00 5072 3.00 3754 5.00 2452 7.00 1214 8.00 658 9.00 276 10.00 772 10.20 869 10.50 1067 10.60 105 10.70 1191 10.80 1497 10.90 1698 11.00 1898 11.10 2008 11.40 2008 11.60 2435 After conducting the titration process and doing the calculations, the concentration of of Ba(OH)2 was found to be 0.1 mol/L. Calculations In part (B), the concentration of Ba(OH)2 solution was found through serval calculation steps. First, the volume at the equivalence point of H2SO4 was found from the graph produced during the lab to be 9mL, which equaled to 0.009L. Using this value, the number of H2SO4 moles was found from the following equation. Number of Moles = Molarity x Volume Eq(7) H2SO4 Moles = Molarity x Volume = 0.8 x 0.009 = 0.0072 moles of H2SO4 The equation of the reaction was, H2SO4 + Ba(OH)2 ? BaSO4 + 2H2O Eq(8) From equation 8, the ratio of H2SO4 to Ba(OH)2 is 1:1. This implies that the number of moles of both of them was equal. Therefore, as the volume of Ba(OH)2 added was 70mL, the concentration of Ba(OH)2 was found as follows. Molarity= Number of moles / Volume Eq(9) Concentration of Ba(OH)2= Number of moles / Volume = 0.0072moles/ 0.07L = 0.1 moles/L Conclusion It was found out that some solutions were considered to be strong electrolytes like HCl, CaCl2 , and NaCl. This was because of their complete dissociation into the solution, which resulted in forming free ions that conductied electricity. On the other hand, other solutions like Ch3COOH, CH3OH, and tap water were weak electrolyte as they partially dissociated in the solution. Some of the free ions reacted again leaving only few ions. Therefore, the solution conducted electricity, but weakly. The distilled water did not conduct electricity. Therefore, it was a nonelectrolyte. Finally, the titration process was used to determine the concentration of Ba(OH)2 inside the solution, which was 0.1 mol/L.
