First of all, it is worth saying that Gulf Stream influences primarily atmosphere temperatures in Europe. Heinz Wanner says that Gulf Stream transports energy and heat from the southern to the northern hemisphere making temperatures in European countries augment (Tulloch). Subsequently, this means that in case of Gulf Stream stopping European countries will “experience Siberian summers and deep-freeze winters” (What Will Happen When the Gulf Stream Collapses?). North America and Europe are claimed to experience strong winter storms and multi-year droughts (NC State University). Moreover, this will logically lead to impossibility of growing crops and breeding cattle as people ...

The world is on the run to look for the cheapest, easiest convenient sources of energy. It is a mystery why the same world is largely dependent on non-renewable source of energy. It has become blind to other solutions readily available like solar energy.
Solar Energy is a source of energy that is produced from the sun to make renewable energy in a process Concentrating Solar Power (CSP). The heat is transferred through radiation from the sun onto solar panel mirrors (Bradford 5). The heat is stored in these panels to be used later on. This form of energy ...

The year is divided into phases depending upon the weather conditions. There are three seasons in some regions and four in others. Seasons are cyclical and correspond with specific months in the year in every region. The transition from one season to another is not abrupt; one season gradually changes to another and there is some overlapping. The cycle of seasons is natural and smooth. It is the result of the earth’s distance from the sun and the tilt of the axis at twenty three and a half degrees. Two seasons are in sharp contrast to each other ...

People have always aspired to harness and manipulate the surrounding world.

- Load sensing control in hydraulics
Load sensing describes a pump control system that is used in open circuits. The control mechanism involves two steps. First, the load coming downstream induces a pressure on an orifice. The load pressure is sensed and determined. Secondly, the load pressure is adjusted in order to ensure a constant pressure drop, thereby enhancing a constant flow athwart the orifice. In load sensing control, the pressure that is induced by the load is fed through the load signal gallery into the pump. Due to the increase in the load pressure, the load sensing controller ...

If there is one big problem that not only a particular country but the entire world has today, that would be global warming. Global warming refers to a process wherein there is a continuous rise in the temperature of the planet’s climate system. According to experts, since the latter half of the twentieth century, as much as ninety percent of the total rise in temperature accumulated has occurred in oceans and other bodies of water. This is because bodies of water have been identified as dominant carbon dioxide absorbers. However, it is important to remember that global warming ...

Question One

It is essential to understand the four classes of materials; this is because it makes us have a clear understanding of the properties that specific materials should exhibit. This plays an important role whenever there is a need to select materials for use in applications. (Ashby, Hugh and Cebon, 2007). This is due to the fact that for every application there are specific properties required, there is always a need to select that material that has exactly the needed property. Hence, the understanding of such properties ensures that the right material is chosen for the correct application. The four ...

It has been argued that an individual must first perceive an idea in order to materialize an object. Philosophers argue that an individual must perceive an idea before materializing the object. There is no reliable account that seems to interlink objects and ideas, as the representation list approach tends to provide .
This made philosopher Berkeley to believe that objects and ideas are bound to be the atheism and skepticism. Even though thing are perceived in this manner, common sense provides that there exist only two important elements that are engaged in perception; this is what is perceived and the ...

Global warming is the gradual rise of the average temperature of the earth’s atmosphere due to presence of certain gases in the atmosphere that traps heat. Under normal circumstances there are always gases that trap heat in the atmosphere. This is done by gases like water vapor and carbon dioxide present in the atmosphere. Others include methane, nitrous oxide and chlorofluorocarbons. They trap outgoing terrestrial long wave radiation and keep the earth’s atmosphere warm. Otherwise during night time when the solar radiation absorbed by the earth’s surface and the atmosphere escape, temperatures would ...

Introduction

Geothermal energy is a source of energy that has become very common as a sustainable energy source in numerous countries across the world. Geothermal energy owes its origin to volcanic activity that occurs in the earth’s core and mantle. Rain water or water form surface runoff may collect in underground reservoirs of water. The volcanic activity below such reservoirs heats the water. The water is normally trapped such that it cannot escape. This leads to build up of a lot of pressure causing it to become superheated. Eventually, the water rises to the surface through fault lines on ...

Incandescent light bulbs emit light by the heating of the filament inside the bulb. First developed by Humphrey Davy in 1802, the earliest incandescent bulbs were made from two charcoal strips with a high power battery used to pass current trough it. The flowing current lead to the production of an intense incandescent light that became the first component of the arc lamp. Future improvement was done by Warren De La Rue in 1820 utilizing the platinum coil inside an evacuated tube. This design was motivated by the high melting point of platinum that would give the lamp a ...

Energy Flow

An ecosystem is an interactive unit that consists of all interacting organisms in a particular area, along with their abiotic or physical surroundings. Usually, ecosystems are divided into trophic levels namely; producers, primary consumers, secondary consumers and tertiary consumers. Energy is not recycled in an ecosystem, but rather it flows in an ecosystem. In an ecosystem, energy flow can be described as energy transfer from one organism to another. According to McShaffrey (2006), each organism interacts with the ecosystem in 2 ways; obtaining food energy from the ecosystem and contributing energy to the ecosystem. Energy flow starts at the ...

For the purposes of this study, thermal conductivity, heat transfer coefficient and the source terms and the sink terms are assumed to depend on the temperature. In the model being used for the study, the source and sink terms are given as arbitrary functions. We therefore employ techniques on symmetry to find the forms of the source and the sink terms which the extra lie point symmetries are admitted. The method of separating variables is used in the study to get the exact solutions when the equation for the equation ...

Heat and Temperature

The transfer of energy from a high temperature body to a lower temperature body is known as heat. Heat travels in form of waves and like any other form of energy it has the potential to bring change into the matter it contacts. This process is usually accompanied by the transfer of entropy, the energy per unit temperature that goes unused. Heat transfer is usually generated by three types of thermal interaction, mainly, conduction, convection and radiation. Conduction is mostly related to the transfer of heat in solids, wherein the materials are in direct contact with each other and ...

Introduction

Fire is described as the visible result of an oxidation process in the chemical reaction known as combustion. Combustion occurs between an oxidant (source of fuel) and oxygen which results in the release of heat and the source of fuel being converted into another form (Grimwood et al., 2010). When heat is released, light is produced either as a flame or glowing. The fuels which bring about combustion are mainly organic compounds like hydrocarbons which may be in the solid, liquid, or gaseous phase.
The part of the fire which is visible is known as the ...

1.0 introduction
Thermoregulation is basically temperature regulation. It is a homeostatic process where by the internal temperature of an organism is kept constant within a specific range despite fluctuations in the external temperatures. It is important to note that all homeostatic systems use negative feedback mechanism. This implies that whenever there is a change in external or surrounding temperature of an organism, consequently a corrective mechanism is initiated within or without the organism to counter the change. Not all animals can maintain a constant body temperature; this is possible only for birds and mammals. Such animals are referred to ...

1. The human made and natural causes of climatic change visible in the computer simulation

On the computer model, there are quite a number of human activities that have been contributing to climatic change worldwide by producing heat-trapping pollutants in the atmosphere. The first human activity is running of industries in which companies emit heat-trapping pollutants in the global atmosphere (Harris, 2007). As can be seen in the computer model, gases emitted by industries during the daily running contribute highly to the formation of the heat-trapping blanket in the atmosphere. The second source of the heat-trapping pollutant is the ...

What is sunlight?

The sun provides tirelessly every square meter of the earth's surface, which it attacks, with an average of about 1370 watts of power (in the form of electromagnetic radiation). We say that the sun burns, but actually it does not. Instead, the sun is a giant nuclear reactor (Layton & Freudenrich, 2000). This solar energy is called the solar constant, since it does not change, except for minor fluctuations. Solar energy is sent in the form of light waves. Light is an electromagnetic wave. The frequency of light - or how fast the waves vibrate - determines the differences in ...

Is large-scale geothermal energy sustainable?

Geothermal energy is a renewable energy resource as natural processes such as radioactive decay and chemical reactions occurring within the earth constantly replenish it. However, it can be sustainable only if the rate of usage matches with the rate of replenishment. Presently, geothermal energy is used for large-scale power generation and small-scale applications include home heating pumps. Geothermal power plants that use steam and hot water available directly from the ground well to run turbines are called dry steam and flash steam power plants respectively. Alternatively, if the hot water from ground is used to heat a heat exchange ...

Climate Changes and Ozone Depletion

The weather is changing but where and when is very unpredictable. Sometimes it is changing in slow ways but sometimes weather events are very extreme and dangerous. The Intergovernmental Panel on Climate Change (IPCC) in 2001 reported on the “probability of the world being three degrees Celsius hotter by the end of the century and of a distinct possibility of it being almost six degrees hotter” (Lovelock, 2008, p. vii). This is a very scary prediction Ozone depletion is a different type of problem although Henson (2008) has said that the ozone depletion problem ...

It was just another cold day in the frozen land. But my instincts were signalling that it was not a day to travel. The weather seemed gloomy and perilous. Though I was warm in my hirsute, yet I wanted to sit by some fire. It was better to nestle in under a mound of snow and safeguard my balminess. To walk miles on such a day did not seem fascinating at all. Seemed foolish in fact! But something quelled my intuition and drove me to walk along this human- a man with queer actions. I felt a bout of nebulous disquiet which probed me to walk along the heels of this well-covered man- so many thick and dark casings sheathed his legs, hands and ears- his entire body. What was he doing outside? Why does not he stay at where his folks do and cuddle next to a fire? Instead he is trotting around, behaving patiently yet strangely and spitting in the air. I didn’t know exactly what he was up to but one thing was for sure- he would make fire soon. Humans do that so easily. But even with that calibre, it was not a day to travel for him or me. Still, driven by the vague apprehension and expecting to sit by fire, I followed this man. ...
