Essays on STM

“If it has ‘science’ in its name, it ain’t (Minnick).” Those words were said to this writer by the smartest person he ever knew personally, a man with PhDs in Mathematics and Physics, a true scientist. He went on to explain that science, if it is science, can be reduced to mathematics and then can predict. “Science can generate electricity or flatten cities,” he said. The problem, of course, is that whenever one deals with the “soft sciences,” political science or economics (the dismal science) or sociology or history or any of the disciplines that are housed in ...

Question #1: Graphical illustration of energy changes during the formation of the nucleus in homogeneous solidification phenomenon.

The solidification phenomenon of a metal starts with the formation of nuclei in a liquid melt, the nuclei forms a stable nuclei in the same melt, and finally formation of the solidified structure of grained crystals. The structure is illustrated in the following diagrams. Figure 1. Solidification process

Question #2: Comparison between homogeneous and heterogeneous nucleation

In the homogenous nucleation, the nuclei are synthesized from metal solidifying atoms. In heterogeneous nucleation, the nucleating agents are the impurity atoms as well as the container surfaces

Question #3: Production of large silicon single crystals

The large silicon single crystals are generated by the use of pure silicon seed crystals in a silicon melt in the Czochralski process.

Question #4: What are a metal alloy and solid solution?

_____________ University Kosovo is a landlocked territory located in the South Eastern part of Europe known as the Balkans. On average, Kosovo gets hot summer and cold winters ranging from +30 C to -10 C (Independent Commission for Mines and Minerals, 2005). According to a 2013 World Bank report, the population of Kosovo is 1.8 million people. The Central Intelligence Agency (CIA) World Factbook lists the primary crops in Kosovo as being “wheat, corn, berries, potatoes, peppers, and fruit” (2005). Additionally, Kosovo produces dairy, livestock, and fish. The Kosovar industries listed in the CIA World Factbook are “mineral mining, ...

I. The Mind and brain of Short-Term Memory This article discussed about major psychological concepts associated with short term memory and the manner by which the impact brain mechanisms. There was the inquiry about the characteristics of the memory system that permits humans to complete specific tasks. In this article, the focus is on three contexts underlying short-term memory and these are inline according to the premise concerning a) the structure of short-term memory, b) the processes that operate on the accumulated information, and c) the mechanisms of short-term memory that accounts about the process of forgetting. There are ...

Abstract

Profound education is the basis for the successful career development and personal growth of any individual. Many scholars are trying to give an answer to the question of what makes the learning process more effective. Different aspects of learning theory provide answers to some of these questions. Theories of learning can be grouped into following three categories: behaviorist learning theories, cognitivist learning theories, and constructivist learning theories. Many researchers pay much attention to the process of scaffolding that is actively discussed as a significant element of learning process. The researcher Albert Bandura has devoted a number of his scientific ...

Psychology

Shot-term memory has been the subject of several studies on cognitive functioning of the brain. Several approach and theoretical frameworks were employed in the process in order to determine the implications of different factors to STM. In this discussion, the context of STM was examined by reviewing relevant literatures encompassing the varying approach to STM study. STM problems were associated to childhood ADHD, while the other research focuses on the association of visual recall and order recall. These studies involves identifying the relationship between cognitive functioning and STM, which are critical areas in understanding human brain functioning and in ...

This paper will cover oil price dynamics for the period starting from 2005 until the present moment of time. Exact price dynamics will be considered as well as a variety of factors influencing the oil price through the above mentioned period of time. The chart showing the dynamics of crude oil barrel price since 2001 is presented in fig. 1. Figure 1. Dynamics of crude oil price per barrel for the period between January 1, 2001 and April 19, 2016 (Trading Economics, 2016). Before the period, which is the subject of this paper, the oil price had been nearly ...

The main direction in improvement of computer technology is traditional communication, engineering, and biotechnology. It is planned that biotechnology, with the help of computers, will be able to create artificial implants, tissues of organs for transplantation and even “artificial intelligence”, capable to help a person in solving a number of routine tasks. If computer technology evolves at its current pace, in 50 years mankind will witness the advent of the computer with mind that will surpass the human`s in speed of information processing executing billions of operations per second. It is yet unknown what an application an artificial ...

Memory

Memory is always associated with recalling of something learnt at an earlier time ascribed to the description of conscious awareness based on remembering of something of the past, in relation to the set of response and stimuli. According to Baddeley (1997), memory is defined as the process that is used in acquiring, storing, retaining and retrieving information that is acquired through human sense. The human memory is a complicated unitary system with two core divisions; procedural memories that deal with physically based motor skills for instance writing, playing, all conducted via cerebellum, and declarative memories based on facts or incidences ...

European Union: Peril or Panacea?

The European Union (EU) is a collective of twenty-seven countries who came together at the end of the Second World War in the pursuit of peace and cooperation. Since joining together, the European Union has helped to bring about just over half a century of “peace, stability and prosperity.” (Europa, 2011). The Union’s main focus is to unify Europe and to “make war unthinkable and materially impossible” (Schuman, 1949) as discussed by the then French Foreign Minister, Robert Schuman in his proposal to form a ‘supranational’ community which became the EU. Following the horrors of the First and ...

Introduction

This study was conducted by Frenkel S. and B. Bourdin. They carried out this research to assess the various memory sytems (short term) from a developmental view of patients of Down’s syndrome (DS). The study compared the patients’ performance to those of normal individuals of similar mental age. Down’s syndrome is the most common cause of Intellectual Disability (ID). Down’s syndrome, also named Trisomy 21, is a genetic condition which is caused by the partial or full presence of an additional 21st chromosome (Frenkel and Bourdin, 2009). The extra chromosomal material delays the development of a child physically and ...
