(Location of the University)
1. Describe the underlying pathology of COPD. What impacts do these pathological changes have on normal physiology? In particular, describe alveolar ventilation in a normal individual and discuss how this might be different in Mr Wenham. (20 marks)
Chronic Obstructive Pulmonary Disease or COPD is touted to be the third leading cause of death in the United States of America. In 2010, it has claimed the lives of 134,676 individuals (CDC 2013). By definition, COPD presents persistent blockage of airflow in the lungs — thus interfering normal breathing. Those afflicted with such condition generally ...

The global society embarks a large portion of its economy on the level of productivity initiated by industries, factories and manufacturing companies that employ several engineers to run the power plants. Information denotes that these are entities, which employs a large global population to enhance their ability to manufacture the final products. Critically, the entities require trained personnel to handle the material and machines in a professional and ethical approach securing the globe from side effects manipulated by the role of productivity (Davis et al, 40). Critically, sources assert that coal is an important product, which is, used to accelerate several activities ...

Abstract

The number of worldwide issues concerning environmental safety and corporate social responsibility has been on an ever-increasing rate. This is why we can also see a significant growth in the demand for environment-friendly and self-sustaining buildings. The number of domestic and international organizations that monitor and facilitate the standardization by means of a tiered certification of such buildings has also been on an ever-increasing rate. The LEED certification program is one of the most prominent ones in the U.S. and the UC Davis Brewery, Winery, and Food buildings have received platinum grade certification under such program. The objective of this paper ...

What are three major causes of chronic bronchitis?

The three major causes of chronic bronchitis are cigarette smoking, long time exposure to air pollutants (such as industrial or chemical fumes), and inhalation of toxic gasses (Madell, 2016).

What are the major pathologic airway changes are associated with chronic bronchitis?

Chronic bronchitis is the condition affecting human beings that cause a continuous irritation and inflammation of the lining of the bronchial tube. Bronchial tubes are airways that carry air to and from the lungs. Exposure to cigarette smoke, air pollutants, or toxic chemicals causes a persistent cough that leads to the formation of excessive amounts of sticky mucus in the airways that result in inflammation and fibrosis. The mucus blocks ...

Introduction.

Atmospheric pollution can be described as the process to which chemicals, biological material or particulate matter, that are harmful to humans and other living organisms, are introduced into the atmosphere (Jacobson, 2002). Man is considered as the prime polluter of the earth’s atmosphere from his daily activities that involve release of hazardous gas into the atmosphere (Cheremisinoff, 2002). The Environmental Protection Agency (EPA) considers the following six pollutants as principle contributors to atmospheric pollution: Carbon Monoxide, Lead, Sulfur Oxides, Ozone, Nitrogen Dioxide, and Particulate Matter like Sulfates, Nitrates and carbon based molecules (Vallero, 2008).

Indoor air pollution and environmental impacts.

Many energy consumers focus ...

Question #1

Hazards posed when one interacts with hazardous materials available at the refinery and related facilities, including the by-products, incident fire and release of acidic gas.
Crude oil consists of petroleum hydrocarbons. When the products are discharged into the environment through leakage, spillage, or combustion; physical, chemical as well as biological activities occur. The aliphatic compounds in crude oil react with oxidizing compounds like nitric acid, oxygen or heat; they burn to generate carbon II Oxide and water.
Sulfur in crude oil burns in air to produce sulfur dioxide. At about 400 – 500 ppm, exposure to sulfur oxide is considered ...

1. How can the disease described above create a mismatch between ventilation and perfusion? Use your understanding of alveolar dead space and physiologic shunt to explain your answer.
In coal-miner’s pneumoconiosis, respirable coal dust that are inhaled for long periods of time trigger hyperactive immune responses that lead to destruction of the lung. At the beginning, coal dust particles are expelled out of the lung through the function of pulmonary macrophages beneath the epithelial layer of airways and near capillaries (Kopf, Schneider & Nobs, 2015). These macrophages phagocytize the dust particles and transport them to the lymphatic tree or ...

Describe the underlying pathology of COPD and the common pathological characteristics of the condition. Discuss the impact these pathological changes have on normal function, including how alveolar ventilation might be different in Mr Wenham compared to a normal individual.
The hallmark pathological attributes of chronic obstructive pulmonary disease (COPD) are one, poorly reversible airflow obstruction and two, a progressive atypical inflammatory response within the lungs. The abnormal inflammatory response denotes the responses of the innate and adaptive immune systems to long-standing exposure to noxious gases and particles especially cigarette smoke. Notably, all cigarette smokers have some degree of inflammation ...

Delineate the ethical issues and dilemmas the company faced.

The coca cola company has the largest distribution systems globally, and is also among the largest beverage companies marketing four of the world’s top five leading soft drinks (Ferrell et al 2011). There has been ethical issues and dilemmas which have caused it to lose its stand in the global market, stocks as well as deter its future growth. The company had ethical issues related to product safety where they were accused of selling hazardous products to consumers. This happened in Belgium in June 1999, about thirty school children became ill after consuming Coca Cola products. This contamination ...

Greenhouse Gases and their Sources

Greenhouse gases are chemical compounds that are found in the earth’s atmosphere. These gases allow the sun’s harmful sunlight to enter freely in earth’s atmosphere. Three of the greenhouse gases are carbon dioxide, methane, and nitrous oxide.
Carbon dioxide is the main contributor to the manmade greenhouse effect. This gas is normally present; however, there are sources that add the carbon gas level in the planet. Humans, animals, and plants release carbon dioxide when they die. Also, smoke that comes out from factories, machines and vehicles add carbon ...

Industrial pollution is a key contributor to a wide range of environmental issues that we face today. Both the structure and scale of today’s industrial production present serious ethical problems from an environmental perspective. The global scale of industrial production coupled with the large amounts of hazardous materials generated imposes substantial risks on the society and natural environment. Industrial companies are considered the prime cause of environmental degradation. This is because these firms exploit natural resources on a large scale and release highly toxic substances and wastes. Industrial pollution is, therefore, a critical ethical issue that needs to ...

Section 1

Wal-Mart Stores, Inc. is world-known multinational corporation, which possesses chains of large-scale department stores, where the majority of goods can be bought at discounted prices. The success of the business model, developed by Wal-Mart, is determined by wide range of factors, which form the combination, which allows Wal-Mart to have competitive advantage in the rivalry with such competitors as Kmart and Target in the USA and CostCo in Canada.
The first and most important factor of corporation’s success is the fact that Wal-Mart makes best possible use of price-based differentiation. Selling products, which are used by great ...

Knarles and Barkley Case Study

Liabilities under Contract Law
Chetum vs Knarles & Barkley
Fact: Knarles wants to repudiate a contract between Chetum and Barkley.

Issue: Breach of contract. Chetum entered into a contract with Barkley that Knarles, Barkley’s father and business partner, refuses to accept. Does Knarles repudiation of the contract constitute a breach of contract?

Rule of Law: A contract must have the following elements in order to be enforceable: (1) mutual consent, manifested by offer and acceptance, (2) consideration, (3) legality of object, and (4) capable parties (Calamari and Perillo, 1998).
Application: Barkley sent a contract (offer), which Chetum signed (acceptance), ...
