Freud and his followers came up with an unconscious mind account. This serves a significant part in explaining psychoanalysis. There was the division of the mind by Freud into a conscious mind, also known as the ego as well as the unconscious mind. Later, it was demarcated into the id (Instincts and ego) and conscience (superego).According to the theory of Freud, unconscious refers to the processes in the mind whereby individuals create an image of themselves being unaware. Freud came up with a proposal of the hierarchical and vertical architecture of the human consciousness, the preconscious, conscious and ...

Introduction

Weighing machines have long been used for measuring weights of various objects. The basic principle behind weight measurement is balancing of force due to gravity of an object with some known standard. You could easily find weight of small objects by using standard weighing balances having pair of pans i.e. one carrying the object to be weighed and the other is used to put loads of known weights until machine is balanced. This method cannot be applied on large scales involving heavy machinery, vehicles, or even humans. Another traditional method of weighing involves balancing force of an object due ...

The capital budget, unlike the operating budget, is a plan for major purchases, and it covers the acquisition of land, buildings, and long-term equipment among others (Roussel et al., 2015; Dunham-Taylor & Pinczuk, 2009). Comprehension of the capital budgeting process is essential for nurse managers. Such an understanding assists nurse administrators to make decisions that are not only sound in a business sense but those that will allow the most efficient utilization of resources for the delivery of care (Dunham-Taylor, 2009). As the cost of medical services increase, healthcare resources are becoming scarce (Zismer et al., 2011). This necessitates a ...

Phobia is an irrational uncontrollable fear, persistent manifestations of various fears. Traditionally, fear is an ancient companion of humankind. Most scientists believe that the feeling of fear is common to all higher animals, and, to a larger extent, to human beings with their finely developed psyche (Popescu 2013), 406. But if an animal can only be afraid of specific dangers, then a human being thanks to his imagination and the ability to analyze the environment has learnt to experience fear ahead of time (Popescu 2013), 406. What are people afraid of? Of course, each person has various reasons to ...

GENERAL INFORMATION ON DENTAL IMPLANT TREATMENT

Objective of dental implants After losing teeth, the supporting bone segment is no longer essential and begins to gradually disappear (Misch, 2008). Once this begins, the missing portions can be replaced with removable dentures or fixed bridges; this process enhances visual appeal, corrects speech impediments and improves mastication. However, complications can occur when replacing living tissues with artificial apparatuses. Dentures have been shown to decrease the efficiency of the chewing process, initiate additional bone loss and often experience inadequate retention (Knowles, 1958). Furthermore, dentures may require additional support, which affects the healthy teeth that are ...

Abstract

The modern bureaucratic system replaced the previous patriarchal system which had some flaws that slowed down the further development of the society. The administrative bodies make decisions and realize them, resorting to enforcement matters when it’s needed, within their authority. The bureaucracy tries to satisfy the needs of those people that it administrates, while those people are taking care of other things: production of material and spiritual goods, bringing up the new generation, health care, and their own professional and personal development. The bureaucracy acts in behalf of those people who empowered it to manage the public affairs. ...

Introduction

Tension forces act on liquid surfaces, the thread in them is pulled into circular arcs. The pull is referred to as surface tension of the liquid. Surface tension exists uniformly in all directions. The forces affect the shape and motion of liquids that have open surfaces. Tension forces can be understood regarding forces that occur between the molecules. Repulsion occurs in molecules when they are close but attract when they are far from each other. Inside the liquid, molecules are close to each other. Thus, there are slight repulsions. Molecules at the surface of the liquid are some distance ...

Philosophy

Language is the main form of communication between people. Effective transmission of information would be impracticable without it. Such a "talent" appeared from immemorial time and allows groups of people to communicate, exchange news, ideas and feelings. However, before the onset of globalization, this communication was limited to the level of individual nations and peoples. Contact with other people is difficult without the common means of communication, which will certainly lead to isolation. This problem is partially solved with the help of translators. It is necessary to choose a single international language - lingua franca, since neither the worldwide ...

Introduction

The speed of any mechanical waves of most material posses a unique relationship with both the elastic property of the material and the inertial property of the medium. The velocity of a mechanical wave is directly proportional to the square root of the quotient of elastic property and the inertial property. V= Elastic propertyInertial property There are three basic types of pressure waves; infrasonic waves, sound waves and ultrasonic waves. Infrasonic ...

Velocity of Longitudinal Pressure in Sold Bars

Introduction As opposed to the transverse waves, longitudinal waves are not easily visible. They usually take place in one direction. Whenever we want to generate a pulse in an oscilloscope, it is required that the wave travels in a single direction to avoid creation of seismic or spark points due to merging or collision of the waves. Both the longitudinal (compressional) and shear waves travel in the form of bulk matter although the later causes change in volume, shape or layer (Hanyga 15). In order to effectively discuss the elastic characteristics of an elastic material like bars, the young’ ...

In the Penal Colony by Franz Kafka has generated serious debate on the importance of justice and the deeper meanings in the story. Revolving around an explorer who has come to assess the “apparatus” or the executive tool in the penal colony, the tale is of extreme condemnation and violence of inhumanity. However, going into the depth of the story may lead the reader to believe that the author has provided a setting which was devoid of the concept of justice in humanity. This can further be understood by the references made to the Old Commandment which may be ...
