Introduction

Budgeting is an integral part of public programs. The concept of budgeting emanates from the principle of scarce resource planning. According to Rubin, budgeting helps in efficient allocation of scarce resources and suggests choice between potential objects of expenditure (Stillman II, 2009). Public budgeting is essential as public administration have limited resources that need to be allocated to public programs. The prioritising of public programs in line with what the citizens want and required fund allocation to carry out the programs effectively constitutes the essence of public budgeting. However, as argued by Rubin, there are challenges of public accountability ...

Analysis of human failure contribution to process risk – The Case of Blowout in the Gulf of Mexico

Abstract

The Gulf of Mexico is considered to have accounted for roughly 90% of the complete offshore drilling in the United States of America in terms of the oil volume that is extracted. This number can be further equated to approximately one-third of the total production of oil in the United States of America. There are more than 50, 000 wells that have been drilled here since the year 1947 and of these 4,000 wells were dug deeper than 1, 000 ft. of water. As of date, more or less 80% of the total offshore drilling happens at a ...

Sodium plays its role in the human body as electrolyte. Its purpose in the body is to maintain normal blood pressure, helps in the absorption of nutrients, regulation of the blood volume and maintenance of the cell membrane potential. The quantity of sodium found in the blood has a close connection to the amount of water found in the body. The level of sodium found in the blood is determined by the amount of sodium and water consumed as well as the amount excreted in the urine. Some sodium is excreted from the body through sweating and stool. When sodium ...

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 ...

What is a Rain Screen?

The rain screen is an exterior defensive coating that sits away from a structure’s outside wall's weather contrary barrier, creating an air crater directly behind the covering that helps to protect the buildings important weather contrary barrier, by providing a moisture management instrument allowing air intrusive through to vaporize any lingering moisture between the structure’s walls.

It is an attempt to understand the architectural and design structure concerning the background check and application of vital principles used in back ventilation and pressure equalized rain screen principles. These systems provide drainable compartmentalization to limit water penetrating during heavy rains ...

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 ...

1) What is the pharmacodynamics effect of angiotensin-converting enzymes inhibitors (ACEI'S and angiotensin II receptor blockers (ARB'S) in reference to the cardiovascular system? 

The pharmacodynamics effect of angiotensin-converting enzymes inhibitors (ACEI'S) and angiotensin II receptor blockers (ARB'S) in reference to the cardiovascular system is based on its overall function of inhibiting the function of angiotensin II and aldosterone hormone production (Woo & Wynne 12). These drugs are purposely used to control high blood pressure, and they tend to act on the renin angiotensin aldosterone system to lower blood pressure. The mechanism of action ARBs is quite different from ACE inhibitors which act by inhibiting the formation of angiotensin II, which increases blood pressure by stimulating smooth muscles and water retention ...

The process of consolidation

Consolidation is compressing soil by applying a force. The result is that volume decreases. The decrease in volume occurs because air and water is expelled from the voids of the soil thus reducing the pores. There are two types of consolidation (1) Primary consolidation and (2) Secondary consolidation. In this paper, these two forms of consolidation process will be described. Soil samples were collected and consolidated over time.

Primary consolidation

This consolidation occurs when all water from the soil is expelled by application of a force. Volume of the soil is reduces in the process. The expulsion of water from the voids ...

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 relief valve acts as the fuse or circuit breaker in an electric circuit. An electric circuit blows a fuse unless it overloads. The hydraulic circuits allow the relief value to dump. Protecting the pump from the excess pressure is the main function of a relief valve. The direct acting relief value responds quickly to the pressure tries to go and observe ...

A better understanding of thermodynamics may be achieved by understanding the general molecular structure of matter as it exists in water and steam. Molecules are the smallest amount of the compound material that has complete chemical traits of that element, which can exist. Molecules consist of smaller particles that define basic elements called atoms. Most minerals constituents can exist in solid, liquid and vapor states called phases. The three phases of a substance can only coexist in equilibrium at a given temperature and pressure. In the liquid state, the molecules can move, but they are still one molecular diameter apart to ...

Norms are a collection of beliefs on how a certain group of people should behave. They are elements that are considered as informal understanding that governs individuals and the behavior of the society. Ideally, social norms are behaviors and prompts that exist in a society. Amplified efforts to establish social norms within a human being are regarded as the most effective activities of the society. This is because they approve and disapprove the different ways through which people carry do things, talk, and dress (Cherry, 2013). However, these norms are different due to the different societies that exist in the universe. For instance, ...

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 ...

Standardized testing is a system whereby learners sit for the same test, and are subjected to similar conditions for taking the test.

People have been using lift for already more than a hundred years. Lift – is a component of the aerodynamic force which is perpendicular to the vector of the velocity of the motion of an object in the steam of liquid or of a gas which results from asymmetry of the body flow by a stream. It occurs at the motion of any object in the air, if the object has a shape conducive to this (the wing, for example). Air flow around the wing is divided into two streams: over the wing and under it. Lower flow steams in a normal manner having no ...

Introduction:

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 ...

CHRONIC VENOUS INSUFFICIENCY AND DEEP VEIN THROMBOSIS

The causes for chronic venous insufficiency are attributed to three types of abnormalities. First one being the varicosity of veins second is the incompetence of the valves which are responsible for a unidirectional flow in the veins and third is the deep vein abnormalities. Formerly it was also known as post phlebitic syndrome post thrombotic syndrome depending on its remote cause (Weiss, n. a). However in some patients the cause could be attributed to congenital absence of the valves. Varicose veins are dilatation, tortuosity and elongation of the veins. It can occur as a result of occupational hazard, prolonged standing may ...

Introduction

According to Huether (2012), venous insufficiency is a medical condition characterized by the inability of the veins of the lower extremities to effectively push blood back to the inferior vena cava. The venous blood evades its normal antegrade flow path and refluxes down the veins in the lower segments resulting to lower limb venous congestion. Syndromes in this condition are mostly due to valvular incompetence common in the low pressure superficial venous system, although they may also be due to incompetence of the valves in the deep venous systems.

Pathophysiology of CVI

The failure of the valves of superficial veins is attributed to ...

Introduction

Hypertension is one of the most common clinical conditions that afflict most people regardless of country or race. Hypertension is a non-communicable disease, which means that it is not acquired through contact although mounting evidence through numerous studies suggests that the disease can be genetic or hereditary. In layman’s term, hypertension is commonly associated with high-blood pressure although in a medical perspective, hypertension is quite difficult to define. The definition of hypertension is quite arbitrary depending on factors such as age as well as the level of blood pressure that is normal for a person, which varies among the population. For ...

The study of Jonestown is one that is scary as well as intriguing. Learning about the movement of such a group of people to follow one person is extremely interesting and it is one that is never truly observed on this scale very often. This paper looks at the movie Jonestown as well as the theories which have been taught in class. I look to apply these theories to the movie over the next few pages. The psychological idea that will take most of my time is that of conformity, this idea is one that is obvious when discussing a situation ...

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 ...

A human’s normal heart rate is the resting heart rate. In some other cases, the heart rate may raise above the normal or even decrease the normal heart rate. Apparently, some factors have been established to increase the heart rate while other decreases the heart rate. As established from the exercise undertaken, the major factors that increase the heart rate are predominantly the strong emotions that include anxiety, embarrassment, and anger. Additionally, other factors established to increase the heart rate include exercise, taking too many sugars and stimulants, this normally increases body metabolism at the same time the heart ...
