...Heat Conversion Name Institution Heat Conversion Matter refers to any substance that occupies space and has weight. It comprises of atoms and molecules that are constantly in motion due to energy that they possess. Energy is present in all matter mostly in form of heat energy. Energy takes various forms and can change from one form to another form. Other than heat energy, various forms of energy include electrical, light, mechanical, chemical, sound and nuclear energy. These different forms of energy can cause a substance to heat up by simply increasing the speed of the molecules in the matter. Molecules therefore, have characteristics of warmth and coldness depending on the form of energy they possess. Since the particles are constantly moving, they possess kinetic energy, which is also one of the various forms of energy. Relationship between heat and kinetic theory of matter Kinetic theory of matter explains that, matter is in a constant random movement. Applying heat on molecules cause the particulars to move in a random motion. Heating transfers heat to nearby molecules in a substance, which becomes excited and then stimulates the surrounding molecules into motion. The process of molecules excitation continues until all molecules move in a vigorous random motion (Goswami et al., 2010). In this process of molecules excitation, the kinetic theory of matter links together with heat. Heat Heat is the transfer of energy that results from temperature...

...Abstract When software is being purchased for a company we must thoroughly examine all parties involved and make sure all input is considered before making a purchase. Key players that are not involved in daily IT functions were put in charge of purchasing new software and the users and IT personnel were not contacted on what the new system should do or what features are wanted. Introduction This assignment is a case study that shows the failures of a business while integrating over to a new software system. The MSCC displayed many areas of poor judgment on technology and software in the business. They were running on old system and software into the 21st century. The time to upgrade to more current systems had long past. Problems will arise when management and support staff are not on the same page when it comes to technology decisions. Improperly trained IT staff and office politics slowed the integration process to a standstill once the new system was approved. Improper steps were also taken by IT staff as no plans were laid out to what steps to take during the process. We will look at each key player and the roles they had in the case. We will also look at what steps we would need to take if we were in Leon Lassiter’s place. Questions 1. Who are the key players in the case and what are their respective roles? 1.1 Leon Lassiter – Lassiter was brought on work at MSCC during a time where they were struggling to keep the budget balanced and produce revenue. It pioneered...

...Question 1 Mass customization, using mass-production technology to quickly and cost-effectively assemble goods that are uniquely designed to fit the demands of individual customers provides a competitive advantage to organizations (Daft, 2010). Mass customization has three main capabilities, elicitation, process flexibility, and logistics to meet customer demands (Zipkin, 2001). Elicitation is the process of providing consumers the ability to communicate what they desire, whereas information is gathered and processed. Process flexibility is the ability of an organization to take the information and provide or produce the customized product or service requested by the consumer. Once the service or product is ready, the logistics is the collaboration of the organization’s processes to employ or deliver the product or service. Mass customization may also be used in service firms, whereas unlike a manufacturing organization, service organizations accomplish their primary purpose through the production and provision of services, such as education, health-care, transportation, banking, and hospitality (Daft, 2010). An example of a mass customization utilized by service firms are colleges that offer specialties degrees. Students attending college may have a specialty they would like to pursue when obtaining a degree. Degrees offered at a college may be generalized such as obtaining a MBA, or more specialized such as a MBA with a cognate in marketing, project management, accounting...

...we encountered in this case are lack of IT knowledge, inappropriate planning, and ineffective and inefficient Resource Management. Each of these issues requires specific attention to fix the next problem and so forth. The solution to attack each individual problem or issue will be explained as follows. Problem #1 Attempting to manage the conversion from an old technology system to a new one without the proper knowledge or background in information technology. Solution Rather than attempting to fix the IT issue, which Leon Lassiter (Vice President of Marketing) of Midsouth Chamber of Commerce (MSCC) had no knowledge about, instead he should have recognized the issue and address it to be taken care by IT experts. Most importantly he should have consulted with the experts of the matter addressing potential problems and solutions while establishing a timetable of completion of the project within reasonable, reachable, and acceptable time frame. At the same time he needs to establish a realistic expenditure budget to avoid draining financial reserves set forth for such expenses. Now, Mr. Lassiter needs to prioritize the full conversion of the new system by October. He needs to hire an additional system analyst to help out Kovecki (System Analyst of MSCC) to transfer all of the data from the old system to the new one. In addition to that, Kovecki needs to order the new modem so that it can allow UNITRAK experts to remote access the new system to help with the difficulties immediately...

...generate additional heat when our body is too cold, and how do we cool off when we are too hot? Although part of this response is voluntary, how do we really know that we are cold, and what is our brain doing involuntarily to keep temperatures constant. At times our temperature will move away from the set point, whether through environmental effects such as exposure to cold or internal processes including fever and exercise. How is Heat Distributed Throughout the Body? Humans are homeotherms, maintaining an average core temperature of 37 +/- 0.5 degrees Celsius. Core temperature varies slightly due to environmental and metabolic factors. Exercise or fever may raise core temperature by up to three degrees, while exposure to cold may lower core temperature by a degree. Beyond these boundaries, the human is susceptible to heat stroke (elevated temperature) or hypothermia, both of which are life threatening conditions. While core temperature is tightly regulated, skin temperature varies greatly in response to metabolism and the environment. Temperature receptors in the skin (cold and hot) detect these changes, initiating compensatory mechanisms through the central nervous system. How Does the Body Produce Heat? Energy in the form of heat is gained by two methods: production (metabolic) and acquisition (environmental). Heat production and retention are elevated by a number of factors. 1. Muscular Activity and Shivering – the conversion of stored chemical...

...el riesgo a los inversores. Si un bono tenía su precio a la par, los pagos del cupón era la principal fuente del retorno de los bonos. Desde que un bono convertible les proporcionaba valor a los inversores como “opciones”, las compañías generalmente emitían convertibles con cupones más bajos como si tuviesen deuda. La opción convertible significa que el bono fue cambiado por un cierto número de acciones comunes de la empresa a precio fijo. Esta opción era válida para inversionistas después de concluir con la vida del bono convertible. El valor de un bono convertible no solo depende del riesgo crediticio y las tasas de intereses del mercado, sino también del precio de la acción, de la ganancia de la misma y la volatilidad. Precio de Conversion = Valor Nominal /...

...is a form of energy in which the sun is used to produce heat that can be used in a variety of ways. This technology has been used for generations and has been constantly improved by modern technology to expand it’s applications. SOLAR THERMAL GENERATION Solar thermal energy is a renewable energy source that converts the heat from solar rays into electricity by indirect means, using steam cycles. Several types of technologies can be used to generate solar thermal energy. Different designs are used as described below; Parabolic trough designs This design uses a curved mirrored trough that reflects the solar radiation directly to a glass tube containing the fluid which runs along the length of the trough. The trough is made to tilt in an east to west direction in order to maintain direct focus of the radiation on the pipe. To reduce convective heat loss, the receiver may be enclosed in a glass vacuum chamber. This design is suitable for operation within an average temperature range from 125º C to 400º C. Power tower designs In this design, flat mirrors are used to concentrate the light on top of a tower. This method is also called the Rankine cycle and it has the advantage of achieving higher temperatures. Dish designs In this design, a solar dish is used to concentrate the sun’s rays on the heating element that is placed above the dish. High temperatures are achieved. This design has the advantage of higher conversion efficiency. Fresnel reflectors A series of long narrow...

...Principal Research Results “Energy Chain”, A New Concept in Evaluating Future Energy Conservation and Greenhouse Abatement Alternatives and Effectiveness Background The energy demand and supply system consists of many kinds of energy subsystems, for example, grid network, fuel (city gas, LPG, kerosene and so on) networks, prospective fuel (hydrogen) networks and demand-side equipments such as heat pump and cogeneration. In recent years, many evaluation methods and factors have been proposed and discussions of energy policy about innovative technology are becoming more multifaceted. In addition, as a result of specialization and segmentation of engineering science, too much discussion has been centered on particular details of efficiency, rather than on the overall needs of the energy supply and demand system. Integration of these evaluations and discussions is necessary for criteria for judgment. Critical review is always necessary to ensure that prospective technologies are really energy saving and contribute to greenhouse abatement over the whole spectrum from producing energy to end-use. Objectives To introduce a new concept of “Energy Chain” from producing energy through transmission, utilization and end-use, and to propose engineering methodology and evaluation method with examples. Principal Results 1.Proposing a New Concept of Energy Chain and Evaluation Method What the energy end-user needs is “energy benefit”. This include all kinds of benefit 1 that end-users...

...EFFECTS OF CLIMATE CHANGE ON POULTRY PRODUCTION 1.0 INTRODUCTION Poultry are birds such as the domestic fowl, Turkey, Duck, Goose, Ostrich e. t. c which are of economic importance to man. Their production is one of the livestock production with significant contribution to human food (Demeke, 2004). It is the primary supplier of eggs and meat as a source of income and employment to people compared to other domestic animals (Avila, 1985). They are raised with relatively low capital investment and readily available household labour. For instance poultry egg contains 74% water, it is a good source of high protein and it is often used by nutritionist as a standard reference for evaluating other protein foods. Studies have shown that the level of performance of poultry does not depends on inherited capacity, but also to a great extent upon the environment (Campbell and Lasley, 1975). The environmental conditions affecting the performance, relative humidity, light, sunshine prevailing at a given time, housing system and ventilation. High temperature and humidity have some negative effects on poultry such as an increase on poultry body temperature: a decrease on feed consumption ( Cowan and Michie, 1978; Howlider and Rose, 1987) and feed efficiency. High temperature also results to a reduction in poultry live weight ( Mowbray and Sykes, 1971), growth speed and high mortality (Arjona et al., 1988) in addition to a decrease on productivity and quality of the eggs (Ozbey and Ozoelk, 2004)...

...efficient data center operation. Manage airflow by isolating cool aisles from hot aisles, and preventing the premature mixing of hot and cold air. • Adjust the thermostat- A thermostat is a control unit for a heating or cooling system or a component part of a heater or air conditioner. Adjust the thermostat up to operate the IT equipment at a maximum of 80 degrees. If your facility uses an economizer, run elevated cold aisle temperatures to enable more days of "free cooling" and higher energy savings. • Use Freeze cooling- Take advantage of "free cooling" to remove heat from your facility without using a chiller. Chillers typically use the most energy, so you'll find the largest opportunity for savings by minimizing their use. As much as possible make use of free ambient cooling such as cooler air, or cooler incoming water. • Optimize power distribution- Minimize power distribution losses by eliminating as many power conversion steps as possible and optimize power distribution and utilization. To optimize power distribution, Google use high efficiency power supplies, minimize the number of times power is being converted from one type of electrical current to another , and keep power supplies as close to the load as...

...Bulbs convert electrical energy to light energy; Mechanical systems in cars convert the heat energy released from petrol into kinetic energy. Second Law of Thermodynamics This law states that energy of all forms moves from higher concentration of energy to lesser concentration energy. When energy moves from high concentration to lesser concentration then some energy is dispersed or spreads out. Entropy is a measure of how much energy is spread out in a particular process. Examples are: When we exercise not all of our energy is converted into muscles in fact more energy disperses away in sweat. The Second Law of Thermodynamics implies that high-quality energy can never be used over again. Once a barrel of Oil is burned its high energy is lost forever. We cannot use the same barrel of oil to burn again. The diesel engine of a generator converts fuel energy into mechanical and thermal energy. During this process of conversion of energy some of the energy is lost or leaked out as heat from the wires of generator or dissipated as heat from the machine. The total amount of energy has not changed but it is now so dispersed that it can never be re-used again. The process of transmission of electrical energy to our homes from power houses also involves the same concept. Electricity is transmitted from high powered wires and during this process wires get heated and some energy is lost as heat in the air. When this electricity reaches our houses it is used to run electrical items like...
