An example of a stimulant is caffeine, this is a widely available substance found in a variety of foods and drinks including coffee, team, chocolate and many energy drinks. When caffeine is consumed it is absorbed straight into the blood stream, which will cause a number of physiological effects on the body. Caffeine is a stimulant, which will thereby increase arousal which is a benefactor for improving reaction…

1.1. Sustainable Development The idea of energy efficient, healthy buildings has been around for a long time, it is now that the concept of “green” or “sustainable” building has entered the mainstream and catching the global attention. There are probably several reasons; Global Warming, rising energy costs, the growing awareness, declining oil reserves, and concerns about our limited water supply. The list goes on, but whatever the reason or reasons; energy efficient building is a concept whose…

Introduction Graphene is considered as pure carbon in the form of a very thin, one atom thick nearly transparent sheet. It is very strong for its low weight (100 times more stronger than steel and it conducts heat and electricity efficiently. While scientists had theorized about graphene for decades, it was first produced in the lab in 2003. Because it is virtually two-dimensional, it interacts oddly with light and with other materials. Researchers have identified the, ballistic transport of…

4. Enhanced Geothermal Systems (EGS) In principle, a temperature of 130C could be reached at any location of the planet at a sufficient depth. For instance, temperatures of this level can be found at depths between 5 and 10 km in half of the surface of USA. Based on this fact, enhanced geothermal systems (EGS) aim at utilizing the heat available at high depths by injecting a heat transfer fluid through a well. Although today few geothermal wells are deeper than 3 km given the high drilling…

researches conducted by Energy Commission of Nigeria and 9 Global Energy Network Institute (GENI) have concluded that 100% stable power supply from 10 renewable energy is possible in Nigeria. Yobe State (relatively rural and under developed state) 11 is located in North Eastern part of Nigeria with Damaturu as state capital. The capital itself is 12 facing serious power crisis, not getting even an hour of electricity from the…

Both of these systems of energy production have their advantages and disadvantages. The pros for renewable energy include: ensured availability, low carbon admissions, and a large scale job creation. The cons, however, consist of: high development costs, unreliability, and the inability to produce large quantities. On the other hand, the advantages for non-renewable energy are ease of accessibility, cost efficiency, and the ability to produce a large amount of energy. While the disadvantages…

adrenocorticotrophic hormone and also T3 (triiodothyronine) and T4 (thyroxine) hormones from the thyroid gland also play a role. Regular uncontrolled fluctation in blood glucose levels can have severe detrimental health effects, the most serious of which is the development of diabetes mellitus, which if left untreated can be…

But all sound waves are different too and they are many components that play into this. The energy something makes when it vibrates produces sound waves that have a definite pattern. Each wave can be big or small. Big sound waves have what's called a high amplitude or intensity and we hear them as louder sounds while small waves are the opposite…

Energy transfer in a refrigeration system. Coefficient of performance of a refrigerator is the ratio of: The method of plotting P-h cycle diagram: 1. By noting the following procedures, the P-h cycle diagram can be plotted: (i) Condensing pressure…

to the local communities. Hence, Lenferna asserts that Africa must be encouraged to actualise a domestic green energy revolution. Firstly, Lenferna discredits Lomborg’s view that Africa needs fossil fuels. He states that Lomborg ignores projections such as the International Energy Agency’s (IEA) Energy for all Scenario which aims to provide universal energy access through renewable energy sources.…
