INTRODUCTION Background Aerospace design applications rely heavily on weight reduction, structural integrity and optimize performance. Engineers and designers have adopted carbon fiber composite due to its high modulus reinforcement fibers embedded in an epoxy matrix. Also called graphite fiber or carbon graphite, carbon fiber consists of very thin strands of the element carbon. Each fiber is 5-10 microns in diameter as shown on Figure 1, one micron (um) is 0.000039 inches. Carbon fiber composite

Marijuana mysteries: 5 things we still don’t know about cannabis and how it could affect our bodies Let’s be blunt – marijuana is a hot topic in today’s political atmosphere. With more and more states legalizing it for medicinal and recreational use, the drug will likely appear on the ballot come November. Yet, despite being historically popular – the most widely used recreational drug in the world behind alcohol and tobacco – we don’t know much about this notorious plant. Marijuana remains a mysterious

The prolonged inhalation of mineral particles, usually in a work environment, can lead to a serious lung disease known as pneumoconiosis. Inhaled particles can permanently embed themselves into the pulmonary tissue and cause inflammation that can lead to scarring of the pulmonary tissue. The most common forms of pneumoconiosis are silicosis, asbestosis, and anthracosis. Depending on the type of mineral dust the patient was exposed to, the radiographic appearance of the disease in the lungs will appear

This capability offers a smooth draw despite the amount of smoke inhaled. Warm water kills any bacteria available in the smoke, providing a cleaner inhalation. This can minimize exposure to most common smoking-related conditions like bronchitis, if used in moderation. For people who are used to rolling their cannabis into joints, the use of bongs will provide cooling percolation while at the same time

hours (U.S. Environmental Protection Agency, 2012). This also assumes method of exposure is via inhalation for workers. However, due to the nature of tetrachloroethylene, particularly in vapor form, this means that residents in the vicinity of dry cleaning businesses and metalworking operations are at risk for exposure to PCE via inhalation as well. The amount of PCE residents are exposed to via inhalation can also be manipulated by the weather on any particular day. Windy days can mean less exposure

oxygen haemoglobin saturation by comparing normal breathing, hyperventilation and hypoventilation in university students. Introduction Ventilation, the process for gas exchanging between lungs and air, involves the inhalation and exhalation to maintain homeostasis. After inhalation, the first gas exchange takes place in alveoli. Due to the difference in partial pressure of oxygen (pO2) between the bloodstream and the alveoli, oxygen dissolves to diffuse into the bloodstream and carried by the red

Function of the heart Aortic valves Pulmonary valve Right atrium Tricuspid valve Bicuspid valve Left ventricle Right ventricle Function of the heart The role of the heart is to pump blood through the body towards the circulatory system this helps to keep you alive. Also the role of the

Name: Bianca Joyeux Causative Agent: Bacillus anthracis Disease: Cutaneous and inhalation anthrax Classification of the causative agent: B. anthracis is a gram-positive spore forming bacteria History: Anthrax was thought to have caused the 5th plague in the 10 plagues that occurred during Moses' time in Egypt. Other names include Ragpicker's disease, Wool sorter's disease, and Black Baine When Koch's postulates were being proven, the first bacteria used was B. Anthracis. Virulence factors of

page 759 Cyclohexane is an acute irritant with low order toxicity due to its efficient metabolism and excretion. Methods of transmittance are inhalation and ingestion. User that has skin contact with cyclohexane will also have some unfavourable topical effects (example?). It is generally considered to be a safe solvent for industrial use

Salbutamol (also known as albuterol in USA) is one of the most famous short-acting β2 agonists. It has become first line treatment for asthma due to its effectiveness. I met this drug in a dispensing session in the first term and I think is a good example of what we have learnt so far. In this essay I will tell you what I know about this drug. Salbutamol is sold in its sulphate form and is marketed as a racemic product. According pharmaceutical chemistry this means that in it, it has 50% of the
