6th BIOLOGICAL CRISIS WHICH MAN IS THE CAUSE ABSTRACT This article will discuss the biological crises the Earth faced since the creation of the living organisms. Then, this article will argue the reasons why human beings generated a 6th biological crisis. Finally, this article will explain what the elements of this 6th biological crisis are. KEYWORDS Biological crisis, Extinction of species, environmental ecosystems, massive extinction, ecological niches, Industrial Era, greenhouses gases,…

South Asia, is the home for one fifth of the world’s population and is known to be the most disaster region in the world regarded as world’s poor region. In South Asia, bout 456 million people are estimated to be undernourished. In the recent past, climate change appeared as most critical issue facing by the society on a global basis, with serious problems of food security of billions of people in the developing countries. The inter-annual, monthly and daily distribution of climate variables…

Instantly a person will think if a room is clean or not; in a way a person will tell if another person is attractive or not, so when it comes to the cleanliness of a business it is important but more so when it comes to a church. The big jobs such as vacuuming and basic cleaning of rooms and restrooms are all important and known, but the little jobs entailed in each room make for the final appearance and make the biggest difference. If you were to professionally clean and polish your car rims…

This means they are taken via the mouth, in the form of a tablet, capsule, liquid or suspension. These medicines come in a variety of shapes and sizes, colours and tastes. Solid dose oral formulations are made either as tablets or capsules, and are formulated to aid compliance and reduce adverse effects. As well as tablets and capsules, oral medicines can also be delivered by liquids, suspensions and syrups. Again, these are formulated to aid compliance. Liquid preparations are measured when…

The Burkholderia Taxonomy and Genomics Burkholderia pseudomallei (Bp) belongs to the Burkholderia genus which contains over 40 species that inhabit a variety of ecological niches. The majority of species within this genus are non-pathogenic soil-dwelling bacteria, but a few species are highly pathogenic to humans and can result in severe disease [1]. This includes B. mallei, an obligate mammalian pathogen and the causative agent of glanders, which primarily affects horses and other solipeds…

1. Discuss the pathophysiology of asthma. Asthma occurs when a patient’s airway becomes narrow, swells and produces excess mucus. The patients’ breathing becomes labored and causes shortness of breath, wheezing, and coughing. Asthma may be minor for some patients, but for others it may cause severe complications. Asthma may also interfere with activities of daily living and in some instances can be life threatening. Asthma is not curable, but the symptoms can be managed with medications.…

CHAPTER ONE INTRODUCTION 1.1 RESEARCH BACKGROUND The US Environmental Protection Agency (EPA) and the US Consumer Product (1995) (as cited in Preethi, 2005) sated that people spend approximately 90 percents of their time being indoors. Therefore, for many, due to more exposure of indoor air pollution than outdoor air pollution the risk to health may be greater. The building occupants may be exposed to the variety of contaminants whether in the form of gases and particles derived from office…

Virginia Beach Emergency Operation Plan ESF 10 Analysis Hazardous materials (HAZMAT) incidents are dangerous types of emergencies that can turn into a major disaster. Despite, many cities that run along the Atlantic Ocean become divested by tropical storms and flooding, HAZMAT related emergencies are a close second. In Virginia Beach, VA hazard risk are delineated into four categories: Critical Hazard – High Risk, Critical Hazard – Moderate Risk, Noncritical Hazard – Low Risk, and Negligible.…

Chapter 2 LITERATURE SURVEY 2.1. Characteristics of Hydrogen Sulphide 2.1.1. Physical and Chemical Properties H2S is a colourless gas characterised by a rotten gas odour which is highly toxic. It is soluble in different liquids including water and alcohols. It is typically formed under deficit oxygen conditions in the presence of organic matter and sulphate compounds (WHO, 2003). Hydrogen Sulphide is also present in the atmosphere in the range of 0.0001-0.0002 ppm though it may vary with places…

Mixed contamination of PAHs and metals occur ubiquitously in the environment, but their combined toxicity to humans and other organisms are not fully addressed. The data from epidemiological, animal and in vitro studies indicated the nature of interaction between PAHs and metals varies from synergism to additivity or antagonism. In this chapter, the combined toxicity of PAHs and metals on toxicokinetic and toxicodynamic endpoints, and possible mechanism of actions were discussed. In addition,…
