Introduction

The term ventilation is constantly used by fire fighters and the fire marshals department. In simple terms, ventilation is the process through which toxic gases, smoke and heat is removed from a burning building and consequently replaced with cleaner, cooler and air rich in oxygen. This is part of the rehabilitation process of a burning building. The process has two distinct components. The first component involves the removal of hot air, smoke and toxic gases. The second component of the ventilation process is pumping in cleaner, cooler and air rich in oxygen. While performing this process, it is important to exercise ...

Virginia Woolf's novel, Mrs. Dalloway, is considered by most to be a baffling read. This is partly because the novelist, Woolf, experiments with the technique of connecting the character's internal and external dialogues in the text. This is quite obvious in the author's characterization of Mrs. Dalloway or Clarissa, the protagonist of the novel, and Septimus. Many critics contend that both of these characters are a doubles. This idea, of course, comes from the “Introduction to the Random House edition of her novel” which states that, “‘Septimus, who later is intended to be her [that ...

Abstract

Hypertension is a silent killer that afflicts over 77 million people in USA. The prevalence of this disease is higher among African-Americans than other ethnic groups. Especially, more than half of the population of African-American women suffers from hypertension and the associated disorders. Apart from genetic factors, a slew of environmental factors including obesity and lack of activity, diabetes, poor diet, alcohol consumption and stress are contributive to this growing phenomenon among black women. This paper has discussed this issue in more detail along with the recommended interventions necessary to keep this condition under check.

The sociological strategy toward social problems varies from other approaches in that the sociological strategy has a focus on self-consciousness and building attention that causes outside of the single person's control or area of command can frequently influence the interaction with community. Certain problems in consideration are more essential, than other problems due to a sociological viewpoint that obtained popularity in the 1960 was “Social Constructionism” (Mooney, Knox & Schacht, 2012). This viewpoint states, when attempting to describe why community places more importance on some problems rather than others that “they (the issues) become real only when they are subjectively defined or ...

Airfoil design and selection is an important deciding factor in aircraft performance. Airfoil is a term used to describe the cross section of the aircraft wings. By observing birds in flight, man has understood that flat plates, resembling bird’s wings can produce the necessary lift to set the aircraft flying. However the actual importance of airfoil in designing the wings of the aircraft was recognized only in 1800. Since then many engineers have designed, tested and patented a number of variations in airfoil pattern. Over the years, there has been a remarkable advancement in technology of airfoil construction and also in ...

A wound can be described in several ways i.e. by its aetiology, anatomical location or whether it is acute or chronic. However, these definitions, serve a critical role in the assessment and proper management of the wounds. An actual account, its definition can be broken down into the skin’s protective functions: continuous epithelium loss with or without connective tissues being loosed. This is as a result of an injury caused to the skin by either surgery, blow, cut or even chemicals. A wound can also be said to be any type of an injury that causes harm to the skin. ...

Abstract

The fugacity is a term that has Latin origins, referring to pace and speed. Early work somewhere in the 20th century, on fugacity, demonstrated that chemical equilibrium is established by the free energies of reacting material. Since then, various approaches and concepts on fugacity have been provided. The gas fugacity of noble gasses has been studied, and models have been proposed for calculating the solubility of noble gasses. The development of various models has considered pressure effects, differential equilibrium between components and temperature changes.
The paper discusses the evolution of various multimedia fugacity models and the fugacity of pure ...

Aneurysm is a word that we mostly use to describe a balloon-like bulge in an artery. Arteries, on the other hand, are blood vessels that carry blood away from the heart. The walls of the arteries are usually thick enough to withstand normal blood-pressure. These walls could however become damaged due to some genetic conditions, trauma or sometimes due to injury to the walls of the arteries. The pressure of the blood against the damaged arterial walls could sometimes result in the accumulation of blood which leads to an aneurysm. Some types of aneurysms exist at birth while others develop during a ...

The above does not mean that the process is devoid of challenges. Often, the system needs to be adequately assessed for the detection of anything that might ...

Comparison and contrast of Umbilical and Nuchal cord

Introduction
Prolapse in umbilical cord occurs in very rare circumstances. This condition is manifested by removal of umbilical cord from cervix before the delivery of the foetus. This cord serves as a food pipe to the baby for the transfer of nutrients from mother to foetus and also collects the digestive waste products from baby. During prolapse, the cord twins around the baby which complicates the delivery. This disease condition occurs only 1% of pregnancies. Due to the higher risk of foetal fatality, umbilical cord prolapse is considered as a medical emergency during labor pain (Critchlow et al., 1994). There ...

Available empirical evidence and facts points to the direction that potassium is a critical component in the human body as a regulator of blood pressure. The above stems from surveys and data recorded over a cross-sectional spectrum of the human population to the effect that areas and regions that take less of potassium have a likelihood of suffering blood pressure-related complications. It is to say that people who take less of potassium have a higher prevalence and prospects of getting hypertension. This logic is true and possible since the ion present in Potassium are unique and provide some functions that aid in the regulation ...

Blood Pressure, Hypertension and the Nervous System

Cardiovascular activities within the human body are generally facilitated by the regulation of the sympathetic and parasympathetic afferent and efferent nerve fibers. Blood pressure is the relationship between the vascular resistance and the amount of blood that the heart pumps per minute (i.e. cardiac output). Cardiac output is affected by the following factors: end-diastolic volume, cardiac muscle contraction, and heart rate. While the sympathetic nervous system controls the blood volume and the tone of venous smooth muscle (determinants of end-diastolic volume) alone, the myocardial contraction and heart rate is controlled by both sympathetic and parasympathetic regions of the autonomic ...

Fundamentals

When a fluid flows over the surface of a body, pressure is exerted on the body. This pressure multiplied by the surface area results into a force, since pressure is defined as this resultant force is a vector quantity with both magnitude and direction. The component of this total force that is perpendicular to the direction of flow of the fluid is called the lift. The other component of this force that is parallel to the direction of flow of the fluid is called the drag. If the lift force is positive, the object is able to fly but if negative, the object ...
