Summary on Cogeneration Cogeneration is the simultaneous production of power/electricity‚ hot water‚ and/or steam from one fuel. Cogeneration plant can reach system efficiencies exceeding 60%. Cogeneration is an enery-efficient‚ environmentally-friendly method of producing electricity steam and/or hot water at the same time‚ in one process with one fuel. It is a way of recycling energy. Molasses which is obtained from sugar is used together with fossil fuel to produce the heat energy like steam

Ownership Having things‚ we all like having things. Media and popular culture is rank with the need and competition for the ownership of tangible things. By this bigger car! Get this special spoon-fork hybrid! It is a constant and dangerously consuming race and it is not surprising that because of it some philosophers‚ like Plato‚ have concluded that ownership is damaging to one’s morals. But then there are philosophers like Aristotle‚ who say that tangible ownership can help develop a person.

Globalization can be conceived as a process (or set of processes) which embodies a transformation in the spatial organization of social relations and transactions‚ expressed in transcontinental or interregional flows and networks of activity‚ interaction and power (see Held and McGrew‚ et al‚ 1999). It is characterized by four types of change. First‚ it involves a stretching of social‚ political and economic activities across frontiers‚ regions and continents. Second‚ it is marked by the intensification

If you conducted a study in which you wanted to determine why help is not given to people who obviously need it‚ with which of the following objectives would you have conducted the study? Explanation- scientific research is to understand the world we live in and it demands a detail exam of a phenomenon. The objective of explanation of the phenomenon

Modernism: * Chaotic society due to the first world war * First called ‘avant-garde’‚ artists (such as musical writers‚ artists‚ poets‚ etc.) saw themselves as alienated from the establishment and aimed to shock and challenge existing social conventions by being chaotic‚ obscure and abtract. * Modernism is a movement that breaks away from classical and traditional forms. Creating different perspectives by breaking boundaries. It’s constantly changing and breaks away from the Victorian

Summary: In 1980‚ Black Entertainment Television was launched by Robert Johnson as a network in programming for African American audiences. BET is popular since it starts. Today‚ BET reaches 87 million U.S. homes and generates more than $100 million in annual revenue. In 2000‚ Viacom purchased BET‚ and Johnson remained in charge as president and CEO of the unit until 2005. Debra L. Lee is the successor of Johnson who had served as the COO for more than ten years. Before Lee became CEO‚ she had been

temperature of the solution at 80 degrees at all times and therefore may cause you to add more or less volume to the titrated solution. Finally‚ over the course of the experiment‚ we noticed different accuracies in the scales we used throughout the lab. The differences between different scales for the same sample go differ by up to 0.100g which could certainly impact the amount of solute we believe we have

Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation

Lab Report: Purpose: The Objective of this lab was to learn how to measure the pH (or acidity) of commonly known fluids‚ using the correct tools and procedures. To then use that data to document the changes noticed when mixing those same fluids and changing their respective pH levels. Materials: In order to conduct this experiment several pieces of equipment and other materials were needed. The first item was a graduated cylinder‚ which was used in order to measure out the precise

-q (metal) = q (water) The specific heat capacity can be used to determine the molar mass of a metal using the equation below. The derivation of this equation was largely based off of an assumption by Dulong and Petit in 1819‚ that one mole of all metals have roughly the same capacity to absorb heat. They found that the heat capacity per weight of many substances hovered around a certain constant‚ and using this derived
