Fundamental interaction

just polished, as detected by SEM and confirmed by the AFM measurements. This lack of coating wear of the disc results from the short test duration due to the ball wearing more quickly. Alumina is a chemically inert ceramic compound and sliding interaction of diamond coatings against alumina material is purely mechanical. Low and stable friction coefficient values of around 0.0804 were observed with the boron doped NCD coating. The stable and low friction coefficient of the boron doped NCD…

In 1943 Abraham Maslow created Maslow’s hierarchy of needs. Maslow’s hierarchy of needs is a motivational theory in psychology that is a model of five human needs. It consists of self-actualization, esteem needs, belongingness and love needs, safety needs, and physiological needs. These five needs can be described as our basic, psychological, and self- fulfillment needs. The five needs are often divided into deficiency and growth needs. Our deficiency needs are the first four levels of Maslow’s…

Motivation is an internal state or process which initiates, sustains and directs behavior in terms of its intensity and direction to satisfy physiological and psychological needs and wants. Theories of motivation aim to explain why we display certain behaviors. Many theorists, including Frederick Herzberg, Abraham Maslow, Clayton Alderfer, and David McClelland have provided theories to help explain needs as a source of motivation. ERG Theory of motivation by Aldefer Clayton Aldefer produced a…

WHAT IS NMR SPECTROCOPY? By definition, NMR spectroscopy is a research technique that makes use of the fact that certain atomic nuclei exhibit magnetic property to determine their chemical and physical properties for various uses that we’ll discuss later. History of NMR Spectroscopy Year Individual Discovery 1921 Stern and Gerlach Basis of quantum theory is confirmed by carrying out atomic and molecular beam experiments 1925 Ulhenbeck & Goudsmith Discovered the concept of spinning…

A1. The Maslow’s Need Hierarchy is given by Abraham Maslow, who has explained the strength of certain needs at the different point of time. Maslow has given a framework that helps to understand the strength of needs and how a person moves from one need to the other when the basic needs are fulfilled. These needs are arranged in the hierarchical form as shown below: (Maslow’s Need Hierarchy, n.d) The hierarchy is made up of 5 levels: 1. Physiological – these needs must be met in order…

As explained above, the governing equations of the gas mixture that include continuity, momentum and mass fraction of the components, are solved at first. Transient conservation equations are as follow: Mass conservation (1) (∂(ε(1-s)ρ_g))/∂t+∇.(ρ_g u ⃗_g )=S_m In this equation u ⃗_g is superficial velocity vector of gas mixture, which related to intrinsic fluid velocity U as following: (2) (u_g ) ⃗=ε(1-s)U ⃗ In the gas transfer channel, the porosity is equal one and the liquid water volume fraction…

Logotherapy is underpinned by the humanistic paradigm, as its key concepts recognise human individuality and freedom, as well as their need to fulfil their potential and find meaning. To understand the connection between humanism and logotherapy, it is important to first take a look at what humanism is, and how it came about. Humanism, often referred to as the “Third Force” of psychology, emerged in the 1960’s in response to what some psychologists considered the shortcomings of behaviourism…

Interest is defined as the requirements, desires or passions of a personal nature and are closely related to attitude. Interest and attitude is the basis of prejudice and passion are also important in the decision making process. Interests cause a person to do an activity that has attracted interest. Enthusiasm is a source of motivation that drives people to do what they want when they are free to choose (Hurlock, 1995: 144). Interest in working to make the person more responsible job. The…

Abraham Maslow is a humanistic psychologist whose contributions to psychology emphasize more of Humanistic approach to modern Psychology. One of his greatest contributions primarily is on the subject of the human needs. In 1943, Maslow developed a theory of human motivation, which is commonly identified as ‘Maslow’s Hierarchy of Needs’ which includes the full range of human requirements to be lead a healthy life (SSI, 2016). Abraham Maslow proposed that most people have a particular number of…
