3.1 Principle of Refrigeration[16]: Mechanical refrigeration is done by three processes that are circulation‚ evaporation‚ and condensing a fixed supply of refrigerant in a closed system. Evaporation takes place at a low temperature and low pressure while condensation occurs at a high temperature and high pressure. Thus‚ it is possible to transfer heat from an area of low temperature (i.e.‚ water storage tank) to an area of high temperature (i.e.‚ environment). Regarding to the fig 3.1‚ beginning

A so-called modern building consumes almost half of its operational energy in cooling or heating the air. In present era of shortage of electrical energy and need of sustainable development‚ we have to think about the way we construct and design buildings before the natural energy reserves deplete and environment

Please provide an example of Homeostasis and Negative Feedback in our environment. Be sure not to duplicate a classmates’ answer. 2. Identify some genetically engineered products currently available. Homeostasis is a point of balance or internal equilibrium. All kinds of systems — both living and non-living — can work to keep themselves in this state of balance‚ but the word "homeostasis" is most often used in biology‚ particularly to describe how the human body reacts to changes and keeps

Renewable energy resources can possibly provide effective sustainable energy solutions. However‚ the application of solar energy for power generation purposes is not currently competitive with conventional fossil fuel systems. A recent academic study compared the solar aided power generation (SAPG) solution with that of a similar-sized stand-alone concentrating solar power (CSP) plant in the South African context. The objective was to determine the real advantages of these technologies‚ if any

The term vegetation means total plant cover‚ roadside vegetation includes the plants that grow near the roadside. Vegetation can be an effective sink for airborne particulates which adheres to surface of leaves (Fowler et al.‚ 1989). In urban areas‚ urban forest ecosystem plays a significant role in the adsorption of airborne particulates‚ thus‚ purifying air and also creating a positive visual and health impact (Wei-Kang et al.‚ 2015). In Urban areas‚ roadside vegetation is fruitful in overcoming

How fever works How does fever happen? Once endogenous pyrogens have been produced by the primary immune response‚ they must travel to the brain to actually induce fever. After their increased production by activated immune cells‚ cytokines such as IL-1‚ IL-6‚ and TNF are distributed throughout the body through the blood‚ as they are all soluble proteins. Now‚ then‚ these cytokines must have a target to signal and cause a reaction. PGE As it plays a central role in thermal regulation‚ it
