Michael Faraday was born on 22 September 1791 in the southern part of London. Due to his disadvantaged background, he was not able to attend full education only achieving basic literacy (Faraday 1). At the age of 14, he apprenticed under a local bookbinder. For the next 7 years, he educated himself by reading books on a wide range of subjects mostly scientific (Hamilton 23; Scientific papers). In 1812, at the age of 20, Faraday received some tickets for a series of lectures conducted by the eminent scientist Humphrey Davy of the Royal University of Great Britain. He attended four lectures and ...

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 ...

The periodic table of elements, by far, stands among the most notable discoveries in the history of chemistry. Nowadays, probably everyone who has ever heard about chemistry heard about the periodic table of elements. Its implications on the scientific world are so enormous that it has even leaked out to the general public and have become associated with the chemistry itself. This is not surprising considering the scientific strength of this instrument. Using the periodic table, many characteristic properties of the elements can be predicted and many phenomena can be explained. This discovery put so much scientific knowledge together, ...

Introduction

David Eagleman’s (2015) book entitled The Brain details scientific discoveries about the way the human brain processes information. The book details the ways in which one’s sensory capabilities and sensory processing activities formulates the way in which one interprets the external environment. It is the combination of sensory capabilities and the processing of sensory input that is largely responsible for the “reality” that one experiences (Eagleman, 2015). The external environment or what humanity would collectively call “reality” is not necessarily what truly exists. Reality may in fact be more subjective or internal than previously thought. Therefore, one ...

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 ...

Introduction

The primary strategic objective of the University of Idaho is to make growth in enrollment at the Institute. The primary strategic objective is set by the current President Chuck Staben. The University of Idaho is not the only institute that has developed this strategy, but several colleges and universities across America are also focused towards the growth of enrollment. It is observed that there is intense competition among different institutes for the growth of enrollment. The reason that all the universities want to increase enrollment at the college is that it is a source of the stream ...

Introduction

Stainless steel is an alloy with iron as major part and chromium with at least 11% by weight . Stainless steel industry grew rapidly during the 1989-93 period . This paper analyzes stress corrosion of stainless steel along with prevention measures and selection methods for stainless steel. After carrying out the study, it would be established whether stainless steel is an effective alloy or not for major uses in steel industry through adopting various selection parameters. Stainless steel is called stainless due to the resistance to rusting and corrosion .

Stress-corrosion in Stainless Steel

Foreword

There is no recipe that facilitates in the development of love in a relation named "marriage". George Bernard Shaw consider marriage is an affectionate mechanism that help two persons to live together with a sense of understanding. He defined marriage of two persons "under the influence of the most violent, most insane, most delusive, and most transient of passions. They are required to swear that they will remain in that excited, abnormal, and exhausting condition continuously until death do them part." The subject of love and marriage is a very interesting one especially as it concerns the status quo of Americans. The ...

The discovery of DNA as the genetic material was one of the landmark events in the field of biology. By confirming DNA as the genetic material scientists made a huge leap that has advanced the cause of medical science to a great degree. While discussing the discovery of DNA as the genetic material, we mostly speak of Friedrich Miescher (1871), the man who discovered DNA. After the discovery of DNA a significant number of studies were conducted that proved DNA as the genetic material. Then Griffith, (1928) conducted studies on bacterial transformation and indicated that genetic information can be transferred from one ...

Introduction

Pesticides are substances or a mixture of substances whose main aim is to destroy, repel, prevent or inhibit the action of any pest. A pest is any form of an insect, plant pathogens, weeds, birds, mollusks, nematodes (worms), and microbes that destroy human foods while in the field, during transportation or in stores. In addition, a pest can destroy other human properties apart from food or help spread harmful diseases. Pesticides are classified into five categories: a chemical substance, a biological agent, disinfectant, antimicrobial and a device. Since pesticides find use in both our homes and in farms, they have the potential of causing ...

Introduction

The thyroid gland is an essential gland found in various vertebrates, and has thyroid follicles (comprised of thyroid epithelia cells), which are supplied by a dense network of blood capillaries. The thyroid tissue’s main function is the biosynthesis and secretion of the thyroid hormone, which is an essential biological molecule existing in either of two forms, T3 and T4. The activity of the thyroid gland is controlled through the neuroendocrine system, which involves the hypothalamus and the secretory actions of the pituitary gland. TSH plays a key role in stimulating the thyroxin-binding globulin (TGB) and the uptake of blood iodine ...

Abstract

Eveslogite, ((Ca,K,Na,Sr,Ba)48[(Ti,Nb,Fe,Mn)12(OH)12Si48O144](F,OH,Cl)14), is a mineral found on Mt. Eveslogchorr in khibiny Massif, Kola peninsula, Russia. It derives its name from this locality, in particular from Mt. Evesglochorr. This mineral occurs as an anchimonomineral veinlet that cross-cuts poikilitic nephiline synite (Hawthorne 2012). This mineral appears to resemble Yuksporite since it forms similar placated fine-fibrous of approximately 0.05 to 0.005mm that aggregates outwardly. The color of Eveslogite is yellow or rather light brown. In addition it is a semitransparent mineral that has a white streak and a vitreous luster. ...

This paper will focus on analysis of a gas fired rotary kiln in the processing of Bentonite. A rotary kiln is a drier that is used for increasing the temperatures of materials in a process called calcinations through a continuous progression. During the processing of minerals such as Bentonite and cement, this kiln is appropriate. Its thermal efficiency ranges from 50% to 65%. This kiln has a cylinder that is slightly incline horizontally and rotates gradually about its axis. Materials that are to be processed are fed into the kiln through the upper part of the cylinder. These materials slowly move to the lower ...
