Introduction

Water degradation is the contamination of water (inland water that’s not saline) with materials or substances that result in the water being unfit for human, plant or animal use. Pollution may occur from chemicals, fecal waste, pesticides, sediments, petroleum or heated substances. Water sources that have been polluted are unfit for fishing, swimming, and the water is unfit for human consumption. Water quality degradation is, as a result, diffuse contaminants at the source with the spatial as well as the temporal variability that’s associated with the sources (Intergovernmental Panel on Climatic Change, 2007). It is more difficult ...

NITROGEN AND COPPER DOPED SOLAR LIGHT ACTIVE TIO2 PHOTOCATALYSTS FOR WATER DECONTAMINATION

Abstract: A new category of photocatalytic coating that can degrade chemical as well as bacterial contaminants under visible sunlight wavelengths was generated by the deposition of a stable photocatalytic TiO2 film over the internal lumen of glass bottles by means of a sol–gel technique. Such a coating was produced either in doped or undoped form. This coating used copper and/ or nitrogen for producing visible light-active TiO2 films that were normalized or annealed at 600 ◦C and were characterized by Raman and X-ray photoelectron spectroscopy. The degradation of methylene blue was seen to accelerate with doped and undoped ...

1. When placed on an agar slab and incubated at 30°C for 2 days, a single yeast cell proliferates into a colony with a diameter of 2 mm containing 108 yeast cells. If the cell has a functional Ade2 gene (Ade2+), the colony will be white; if Ade2 is non-functional (Ade2–), the colony will be red. You take a strain with a mutant Ade2– at the regular chromosomal position (red colonies) and insert a second, functional Ade2+ gene near the telomere. You find that the colonies are a mixture of red and white patches or sectors. Figure 1 ...

Degrading Nature: Rising Sea level in Caribbean Sea

Lately, rising sea level is among the contentious environmental issues and has become more challenging in environmentalism. Rising sea level has various impacts on both the natural environment and human populations, more especially those living on islands and the coastal regions. It is estimated that the sea level rose by about 1.8 yearly in 1950-2010, and this rate keep on increasing with time. There are a number of factors that are associated with the rising sea level. The Caribbean sea-level rise serves as a good illustration of how the sea-level rise is an environmental challenge (Gallagher, 2006). This paper ...

Incinerating means burning waste or trash until what is left is ashes awaiting disposal. An incinerator is a machine used to burn waste and trash until these materials are reduced into ash. The device is constructed using heavy machinery and well insulated materials that protect heat transmission into the immediate environment. Incinerating serves to keep hazardous material from finding their way into landfills where they can harm workers in such facilities (Donohoe 2003, pp. 588). The devices produce power while in process of waste burning that can be used elsewhere. The byproducts of incineration are air and smog pollution, ...

The immune system has an immune arsenal that help in the combat of infections including the challenging viral infections (Iannello 2006). Upon infection by a virus, the host invariably reacts by activating its line of defenses. These immune defenses can fall into two main groups: the innate immune system (first line of defense) and adaptive immune response. The innate immune system is non-specific in nature, but the adaptive immune system is acquired following previous infections or vaccinations (Iannello 2006). However, viruses continue to undergo an evolution and have engineered strategies that evade the hosts’ immune antiviral responses. This paper ...

Introduction

Recent decades have witnessed endless debates among environmentalists and economists on the economic and environmental effect of the current usage of Mexican land. With farmers supporting a policy to strengthen wine production in Mexico, real estate developers are interests in a strategy that would allow urban sprawl on Mexican land. Although, the two ideas are beneficial to Mexican economic development, there is increased concern of the environmental implication of these competing economic undertakings. Real estate developers are by large condemned for facilitating environmental degradation with limited consideration of its impacts on future generation (Johnson 21). On the other hand, ...

Introduction

The novel ‘Silent Spring’ was authored by Rachael Carson. The novel, ‘Silent Spring’ presents a vivid review of the manner in which the environment has been bargained or compromised by some of the most effective pesticides. An example of these pesticides is the DDT. Carson’s major argument in this book is based on the negative impacts of the pesticides that were used in agricultural activities. She insisted that the pesticides killed bugs. However, there was a more serious issue that she intended to address than just mentioning the obvious reason behind implementing the pesticide solution in agriculture. The ...

When designing various projects for a client, an engineer is concerned with different aspects of the design. For instance, the aesthetic value of the design is very important to the engineer. Other factors that concern the engineer are the durability of the product and the cost effectiveness in both the design and production processes. However, and without belittling the importance of these factors, safety is ultimately the major concern of the engineer. Safety as a factor is incorporated into all designs, for both the client and the environment (including other people who might not necessarily use the product but ...

Sorting of the Receptor

Response to questions Q. A Describe the main pathway turned ‘on’ by the EGFR to regulate cell growth MAPK/ERK pathway is the main pathway, which is turned on by EGFR in order to regulate cell growth. This path comprises of a chain of proteins within the cell, which communicates a signal from the cell receptor surface to the DNA within the cell nucleus. When a molecule binds to the receptor at the cell surface, a signal is induced and ends when the DNA expresses a protein, which in turn produces some changes within the cell. One of the common ...

Pollution is amongst the world’s killer threats that many economies try to fight against. Environmental pollution affects the health of over 100 million people globally on an annual basis (Harris, 2012). The search for economic development has been quoted as one of the key factors that initiate environmental degradation. The case in China is no different; for three consecutive decades, China has been on the remark in successive economic developments. This has resulted from increased income from the manufacturing and industrial sector. China is amongst the top regions in the world in production of machines, gases, coal, among ...

Environmental ethics is a discipline that studied the concepts of moral relationships between human beings and the environment (Keller, 2010). It is a philosophical disciple that involves a study of moral relationships, values and status of environment, and its non-human contents. In the recent past, the literature behind environmental studies, the distinction between intrinsic and instrumental values has gained significant importance. This is as a result of massive human activities, which pose adverse effects to the environment (Carnegie and Griffith University, 1996).

Instrumental values, in environmental ethics, can be explained as the valuation of things or activities, which form ...

A polymer is commonly defined as a combination of different compounds that in them have some structures that repeat themselves. The entire process that in the end leads to the development of a polymer is known as polymerization. In essence, it is used to refer to how the various parts are combined to form a polymer. Traditionally, more focus was given on the covalent bonds when linking the compounds of a polymer. This has, however, changed in the recent past, and non-covalent bonds have also been given some level of significance. Polymer is a term in reference to exceptionally ...

The struggle for sustainability in rural China

Evidence from scholarly material has shown that there is an assumption on issues concerning the environment in rural China. These stereotypic opinions have been largely generated by the general public as well as the aforementioned scholars. The first assumption being that the Chinese people do not care about their environment as they are more concerned about their economic development. Secondly, it is assumed that even if the people cared about the environment and were concerned about the pollution, there is little they could do to stop it because the central government has put more emphasis on economic development than ...

Protein degradation is a regulatory process of all living beings that helps to weed out proteins that are faulty in nature. The fault maybe in their sequence or folding. The proteins are degraded via ubiquitin-proteasome system (UPS). The proteasome is made up of an outer activating module and an inner core particle (CP), which in turn is made up of outer α subunits and inner β subunits. The α subunits guard a N-terminal gates pore, which open up when proteasome activators (PA) binds to it. The β subunits have the active sites that can broadly accommodate different faulty proteins for degradation. The CP ...

Introduction:

Security refers to the protection of life from any force or factor that is threatening to it. Traditionally, security has been viewed from militaristic approaches that are related to the avoidance of conflicts between States and Nations of the world (BRAUCH, 2003). The traditional approach to this issue has majorly focused on studying the threats in our world and using or controlling military forces to address the issue. Since the cold war ended, there has been a distinct shift from security studies and international relations in addressing security approaches. The world super powers are no longer the sole determinants ...

- Explanations - Food miles and 100-mile diet A 100-mile diet refers to a diet that consists of foods raised and grown within 100 miles of a dinner table (Tancock). Usually, food travels some 1,500 miles before reaching the dinner table in North America (Tancock). The traveling miles are called “food miles” and affect the environment, quality of food and farming practices. Food miles increase carbon emissions through the numerous planes, boats, and trucks involved in the transport of food materials. In addition, food miles promote unsafe agricultural practices because the consumers are unlikely to visit the farms ...

There are different forms of feminism with five of them expressing strong views on prostitution. These are liberal feminism, Marxist feminism, socialist feminism, existentialist feminism, and radical feminism. Feminism is changing and vibrant, specifically in the cases of liberal feminism and radical feminism. Feminism embraces most tenets of a specific feminist theory rejecting selected precepts outright. In any case, one thing remains certain, and feminism focuses about promoting a world where women enjoy equal shares of power and rights. Radical feminism is against prostitution on grounds that it is degrading to women, and it extends the male gender’s ...
