Abstract

Recently, attention has been diverted to clean, alternative and renewable technologies due to the depletion of petroleum resources and increase of the green house gases from the combustion of fuel resources. Fuel cell is the fore-runner of these technologies and has received immense impetus due to its relatively clean source of energy. Fuel-cells are devices that produce electrical energy from chemical transformation reactions. Electrodes are placed within an electrolyte medium that facilitates oxidation of fuel. In these electrochemical reactions, ions are generated that generate electricity. This electrical energy can be effectively harnessed to carry out a myriad of functions. Since ...

Hydrogen cyanide, abbreviated AC by military, is an inorganic compound that is colorless and is extremely poisonous liquid. It has a boiling point (26°C) that is slightly more than the room temperature. The molecule of hydrogen cyanide is linear and has a triple bond that joins the carbon atom and nitrogen atom together. Hydrogen cyanide has a weak acidic mature with a pKa of 9.2 and is partially ionizes in a solution of water giving cyanide anion. A hydrogen cyanide solution in water, is referred to as hydrocyanic acid while the hydrogen cyanide salts are referred to as cyanides. Hydrogen cyanide is mainly ...

Introduction

Pilots and their passengers experience physiological challenges when they are subjected to environment and the stresses of the flight. Thus, these physiological challenges are the ones that lead to the occurrence of aircraft accidents. It is interesting to note that human physiology is actually evolutionarily modified to be efficient up to roughly 12,000 feet above the sea level. In real sense, this is essentially the limit of physiological efficiency zone. For that reason, outside this zone, the physiological compensatory mechanisms might fail to cope with stresses of altitude. The objective of this paper is to scrutinize an aircraft ...

Introduction

There are environmental chemical processes which require light to react. These processes are called photochemical reactions. Photochemical reaction is commonly initiated due to the absorption of solar energy or light. When molecules absorb energy in the form of light, the atoms are converted in a transient excited state (Larson & Weber, 1994). This transition state or excited has completely different physical and chemical properties with the initial state of the molecule. The excited states also have more tendencies to react since they are considered stronger acids and stronger reductants that the initial state of the molecule. The excited state of ...

Travelling to another planet is referred to interplanetary spaceflight. The term is usually used when travelling to a planet within the same planetary system (Fisher 1). The human race has made tremendous strides in space exploration. Man has made it to the moon and back, which was a great achievement for science as well as the human race. Man may not have stepped onto another planet yet, but significant achievements have been made in interplanetary exploration. There have been explorations using probes that have flown by every planet in the solar system. The New Horizons recently flew by the ...

Asthma is a chronic inflammatory disorder that causes shortness of breath, a feeling of tightness in the chest, and persistent cough. There are two primary types of asthma: intrinsic and extrinsic. Intrinsic asthma comes about through non-allergic means: cigarette smoke, stress, cold air, cleaning agents – basically anything that does not involve an allergen. Extrinsic asthma, on the other hand, comes about through an allergen such as dander, pollen or others. It leads to a constriction of the airway during an attack, leaving the victim out of breath, unable to take in more air, and with a tight feeling in their chest. In this ...

1. Components and mechanisms of the respiratory system
The respiratory system is the system that allow humans and animals to breathe. The main function of the system is to provide oxygen to the body through the blood. Breathing involves two main actions: inhaling and exhaling air. Inhalation brings oxygen into the body via the blood and exhalation chases out carbon dioxide.
The respiratory system is composed of different tissues and organs, including the airways, lungs, bloods vessels and muscles connected to each other to assure a proper breathing process (National Heart, Lung and Blood Institute, 2012). The airways ...

Introduction:

Corrosion refers to the partial and gradual dissolution of materials used in water treatment and supply systems, pumps, pipes, tanks and valves. In most circumstances, almost all water is corrosive and this may lead to structural failure, water leaks, capacity losses and deterioration of the microbial and chemical water quality (WHO 2011). The pipes used in water distribution are made of different materials such as plastic, metals (galvanized steel, copper, lead and iron), and even concrete. Pipes made from concrete and plastic tend to be corrosion resistant.
In piping systems, however, there are several water quality factors working singly ...

Introduction

This term paper explores the issue of weather affecting pollution in major cities. In a major city, where there can be a higher proportion of pollution sources in a relatively small geographical area, the effects are likely to be more distinct and concentrated.
Whilst there are several causes of air pollution, it is known that the air quality at any given time can be affected by the prevailing weather conditions. For example, strong winds can rapidly transport pollutants released into the air great distances from the originating source. Conversely, in conditions when there is very light wind or in still air, the ...

Causation of Climate Change

The world’s climate system is composed of five elements that include hydrosphere, lithosphere, atmosphere, cry sphere, and biosphere. It varies naturally with time and is dependent on the incoming and outgoing energy which determine the optimal balance of the earth’s energy. These determinants constitute factors that cause climate variation that result in either warmer or colder states. This result into a phenomenon referred to as climate change. This is a condition, in which, the earth experiences adjustments in its weather that occurs over a period. This essay provides a detailed analysis of the causes, characteristics, and the impacts of climate change ...

Introduction

An article published by the Cochrane Collaboration and posted in the Cochrane Library in 2012 caught my attention. The article stated that no quasi-randomized or randomized clinical trials of gene therapy for sickle cell disease have been documented. The article further stated that no conclusions and recommendations are attributed to the application of gene therapy on sickle cell disease (Olowoyeye & Okwundu, 2013). This statement inspired me to evaluate the current developments in gene therapy that targets sickle cell disease. Sickle cell disease is one of the oldest genetic disorders and yet few attempts have been made to develop gene ...

The movement from sites of waste-disposal of contaminated groundwater is a problem faced by many cities in world. Solid and liquid waste dumped in landfills generates an atmosphere where inorganic and organic compounds present in the water or which are produced in the landfill become prone of entering the hydrological regime through movement. The movement of contaminants in water bodies through landfills is more distinct in temperate and humid climates as penetration of rainfall is moderate to high, and separation of leachate from the aquifers which are underlying for extended time periods becomes a complex process. In such areas, landfills gets ...

Cancer is one of the most common causes of death worldwide. Every year, various types of cancer kill millions of people. The problem of cancer disease is unique because of its complexity and importance to humankind. Cancers affect all segments of the population, causing enormous damage to society. Although malignant tumors are extremely diverse and complex for the perception, the risk factors and mechanisms of development of cancer are well known enough so that it becomes possible not only to heal, but also to engage in cancer prevention. Cancer is the most difficult and dangerous disease, since it can ...

There are a variety of birth defects that are influenced by the actions of the parent while the child is in utero. From the harmful effects of drugs and alcohol, to the physiological changes that occur within the mother’s body as a response to stress and dietary deficiencies, the influence of such prenatal events can prove to be lifelong for the child. One such disorder associated with the prenatal environment is known as Fetal Alcohol Syndrome (FAS), which falls under the category of Fetal Alcohol Spectrum Disorder. The spectrum of disorders under the FASD umbrella also includes Partial FAS, Alcohol-Related ...

Impacts of Deforestation on Biodiversity

Forests serve as the bank of oxygen. They make life possible on the planet Earth. Every living or non-living thing is either directly or indirectly influenced by forests. Besides oxygen, they support sustainable habitat for people, wild life, and other creatures of the world. Forests offer a substantial environment for endangered and vanishing animal species. They also deliver life supporting benefits that to 1.6 billion population of the world. More than thirty percent of or planet is covered by forests. But, unfortunately, forests are being cleared off at massive scales from around the world in the form of deforestation. It ...
