Background information

The need for clean water for use by humanity has since time immemorial been an area of concern with scientists and scholars inventing methods that prove to be more efficient than their predecessors. The ultimate goal has always been the removal of undesirable chemicals and pathogens that would, however, render the water unfit for human and industrial consumption. In today’s contemporary society, human activity has culminated into pollution of the natural environment including water catchment areas. This has therefore made water unfit for consumption thereby prompting for more cost-effective and efficient methods for purification of this natural resource. ...

Water is a colourless and odourless liquid, and is very important for human development and survival. It covers 75% of the earth's surface and is mostly found in lakes, rivers and seas. In addition, the human body comprises 78% of water. Water is an interesting molecule and consists of one oxygen atom and two hydrogen atoms. It is covalently bonded and possesses a very interesting characteristic, i.e. polarity. Polarity ensures that water is an effective medium for the dissolution of other polar compounds. In so doing, water is an enabler for many biological reactions (“The Chemistry of ...

Introduction

Cloning is a term used to describe different methods of duplicating biological materials. Plasmids can be used to ‘clone in a gene’ and then express a given protein in mammalian cells. The type of protein used here is called AWP1 protein which is associated with PRK1. This type of protein is a universally expressed protein and the AWP1 gene is switched on during the early development of a being. The AWP1 may play a regulatory role in the mammalian signal transduction pathways. The AWP1 posses a conserved zf-A20 zinc finger domain at its C-terminal. When it is expressed in COS – 1 cells, the Myc-tagged ...

Material extraction

The mining and extraction of copper has several impacts on the environment. The extraction of copper is done in several steps and process using different technologies and mechanisms. The copper element is extracted from its ore through heating the ore using carbon. This process releases carbon dioxide gas into the atmosphere. It is a well known fact that carbon dioxide gas is a greenhouse gas which result into global warming. The result of the extraction is copper full of impurities. The impure copper is then placed under further treatment to eliminate the presence of the impurities. In most cases, ...

1. How do you characterize the relationship between the father and his son from the perspective of commitment or-non-commitment to Islam? How does this relationship change during the pilgrimage?
Reda and his father have nothing in common because he is liberal while his father is rigid and very committed to Islam. Reda and his father clash a couple of times because of their differences in commitment to Islam. Reda is more of a secular person and shows no commitment to Islam. His father, on the other hand, is very religious and committed to the Islamic way of life. First ...

Abstract

Carbon capture is an essential approach for reducing greenhouse gas emissions. Different plants utilize various technologies in reducing carbon dioxide emission. Some of the conventional techniques employed include oxy-fuel, pre, and post-combustion carbon capture. These approaches have a high potential for capturing carbon dioxide. However, their massive initial and implementation costs have been a challenge to plants globally. Additionally, most of them are yet to experience large scale applications. Therefore, it is essential for research and development activities to be conducted. This can ensure a reduction in the cost of production. The carbon capture technologies differ in costs. This ...

Artificial blood

Artificial blood is a derived product that acts as a substitute for the red blood cells present in the body (Sódar, et al. 2016). In comparison to true blood, the purpose of artificial blood is to transport carbon dioxide and oxygen to all parts of the body. Based on current evidence, artificial blood can be developed or prepared by recombinant biotechnology, chemical isolation, or through synthetic production (Sódar, et al. 2016). The concept of plasma in artificial blood was first introduced in the early 1600s (was also known as blood substitutes). The search for true blood substitutes ...

Chlorine is the most common and effective disinfectant at the moment is. Among the chlorine-free water purification methods, ultraviolet radiation, the copper and silver ions, ozonation, the use of preparations of the active oxygen of the organic polymer are widespread. In some cases a combination of above mentioned methods is the most effective. Nowadays, new technologies allow to use following methods for water perification.
UV-radiation of a certain wavelength and intensity, when exposed for some time to microorganisms, damages their DNA, making them incapable of reproduction. This principle is based on UV disinfection, it kills even those bacteria which ...

Externalities take place when consumers/manufacturers activities have an unintentional or indirect impact on other consumers/manufacturers without affecting prices. According to Sankar, externalities may cause positive and negative effects (6). In other words, if the consumer or a group grants certain benefits to other economic agents, the externality is positive; if any activity is disadvantageous to other groups or individuals, then the externality is negative (7). According to Stiglitz (216), “Externalities arise whenever an individual or firm undertakes an action that has an effect on other individual or firm”. The externalities phenomenon tends to have a spillover effect in the ...

Shintoism and Buddhism in Japanese History

Before the spread of today’s religion, the early civilizations had different views as to how they could explain the things around them. Some would say it is the work of spirits who dwell upon plants, animals and inanimate objects while others believe in the intervention of divine beings who created the world prior to mankind. While some of these early beliefs have been forgotten in favor of newer religions, there are countries where early beliefs played heavily in the formation of the nation and even triggered a conflict to occur when a new religion was introduced to the ...
