Free Essays on Damage to Get Inspired & Learn by Example

There have been concerns by the Health and Safety Executive (HSE) that workers in the ceramics sector have an increased likelihood of being affected by silicosis as a result of prolonged use of raw materials which contain quartz, feldspar and china clay. The quartz component of the raw materials causes the formation fine dusts which contain small particles that in some cases contain Respirable Crystalline Silica (RCS). Excessive exposure especially for a long period of time leads to a pulmonary fibrosis (silicosis) which results in incapacity and sometimes death. The objective of this study is to access if there Continue reading...

Abstract

Radiation cataractogenesis (RCG) is deterministic. It does not occur below a minimum threshold dose. RCG is generally believed as dose-related. Sliney (1986) believed that its severity is also dose-related. The severity increased and the latency decreased as radiation dose increased above that threshold. The lens of the eye is nonvascular and is known to experience no cell loss over its lifetime, indicating that any damage to its cells will not result to the removal of these cells for lack of existing mechanism. Three induction mechanisms were explored (direct, indirect, and oxidative, which separately creates oxidative stress inside the lens Continue reading...

Introduction

With the advancement of the modern medicine people have discovered more medial disorders and conditions that were unknown in older time. The advance treatment options, critical care, antibiotics and surgical advancements are very helpful in tackling such diseases.
Nowadays, information is available on causes, symptoms and signs, pathophysiology, anatomical abnormalities and genetic designs of every diseases and causative organisms. Vaccinations and prophylaxis measures are also available to prevent most disease.
This paper gives Continue reading...

1. Mechanism that result in a patient showing hyperreflexia and hypertonia
Hypertonia is muscle stiffness. It can also be associated with the increased muscle tone. Reflexes (such as a knee-jerk reflex) in hypertonia are stronger or increased. Hypertonia may hinder walking, movement or speech of a man. Muscles are strained and tight to the touch. Tonus is increased by the spastic type; muscle tone in the study of the resistance is felt at the beginning of the movement (a symptom of ‘folding knife’). The obvious hypertonia is characterized by contracture. In hemiplegia (hemiparesis) in hand, tone increases in adductor Continue reading...

The population of the Earth is seven billion and counting. With the number of resources in short supply, people need to the ways to meet their natural human needs like nutrition. Seeing as how limited the number of arable lands fit for crop cultivation is, there has always been the need for the stimulation of the amount of food produced. Over the centuries, the humanity has developed a great number of cultivation techniques and instruments to provide for the growing number of Earth population. While people do what is a strategic planning calculating the requisite amount of food readily Continue reading...

The Loma Prieta Earthquake 1989

The context critically discusses the factors that are connected to the Loma Prieta earthquake that took place in 1989. An earthquake is a physical occurrence where vibrations are caused by underlying rocks that are breaking under a lot of stress. The rocks are situated under the earth’s crust and are mostly caused when two tectonic plates come together, and pressure is created along the fault lines. It is then released towards the earth’s surface resulting in an earthquake (California, 1990).The Prieta earthquake had a series of damaging effects ranging from the human, social, and economical effects Continue reading...

Hurricane Katrina is one of the most catastrophic natural calamities recorded in the U.S. history. It was the eleventh named hurricane and the fifth one of the Atlantic hurricane season in 2005. The costs of destruction and the number of people who died in the hurricane and floods, that followed it, prove that it was one of the most intense landfalling tropical cyclone ever seen in the North America. It ranks third in the top-five deadliest hurricanes in the U.S and made severe damage to Louisiana, Mississippi and Florida where large numbers of people lost their homes and all Continue reading...

The Day After Tomorrow
Based on the film, “The Day After Tomorrow,” the polluting of the atmosphere caused the climate change. The paleoclimatologist, Jack Hall explained that if this practice is not discontinued, then the earth would experience a climate change, much like the one that changed the climate of the earth into the ice age, 10,000 years ago. He stated that researchers had found that because the polar ice caps were melting and allowing fresh water to dilute the levels of salt in the ocean, the ocean had suffered a thirteen-degree temperature drop. Jack was informed, but Continue reading...

Why We Get Sick

Chapter 6. Toxins, New, Old, and Everywhere
There are lots of novel toxic hazards to which we are exposed. There is alcohol, agricultural pests, nitrates, toxic dust and fumes, spray insecticides that enormously harm our health day by day. It seems obvious that our modern age must be more hazardous than that one our ancestors lived in. But this is not true because the contest between consumer and consumed can generate an evolutionary arms race.
