Throughout history, humans have experienced a wide variety of mental health disorders, some tolerable with counseling, while others disorders requiring more intensive treatment through the use of inpatient hospitalization or medication. Mental health disorders have the ability to touch all aspects of an individual’s life; from daily interactions with family and friends, to the extreme of such disorders leading to successful suicides in an attempt to be free of one’s mental terror. However, through the course of astute studies and passionate researchers, we are closer to understanding how to effectively treat a menagerie of disorders.

Introduction:

The rheocasting process entails the application of semi-solid slurry in metal casting. The process has numerous benefits that are directly connected to solid fractioning during the duration of casting. The process is also known as the semi-liquid casting because it involves the usage of the slurry in the semi-liquid or semi-solid state. The process can be said to consist of two stages, slurry making and direct slurry casting. The method was first developed by R. Shibata for commercial purposes at Hitachi Co. Ltd (Beeley & Smart, 2004).

Rheocasting process description:

The process involves preparation of high quality non-dendritic slurry through the application of ...

In the U.S. two types of standard structural bolts have been approved for use: ASTM A490 and ASTM A395 (Williams, 2001, p. 44).

ASTM A395

Usually, the ASTM A325 covers the heavy structural bolts with high strength that range in size from half diameter to one and half diameter. The given bolts are often used in various structural connections (Williams, 2001, p. 54). They characteristically have shorter thread lengths when compared to the standard hex bolts. There are two types of A325: Type 1 and type 3. Type 1 is made of carbon baron, medium carbon, or an alloy of medium ...

Different parts of a car are made of different material. The choice of material to make different parts of a motor vehicle is influenced by factors like amount of stress handled by the part, cost of material compared to other alternatives and purpose of the part e.g. decoration etc. These are some of the factors the determine type of material a motor vehicle part is made of. An example of material and part on a car made using the material is given below.

Metallurgy

Definition of Metallurgy

Metallurgy is "the science and study of the behaviors and properties of metals” (Tom Bertone Consulting, 2012) and the procedures involved in the extraction of metal from ore. In particular, it deals with the properties of metals and alloys.
Metals are characterized as having the capability of conducting electricity and heat (“Metallurgy,” 2011). They are hard and are dense under room temperature. Alloys, on the other hand, are combinations of metals. An example of an alloy is steel, which is a combination of carbon and iron, although vanadium and chromium may also be added. Other examples ...

Iron

Iron as a chemical element is referred to by the symbol Fe and has an atomic number 26 on the periodic table. Iron is a metal in the first transition series and is the most abundant element on the outer and inner surface of the earth.

Iron was discovered in 2000 BCE when it replaced bronze in manufacture of tools and weapons and ushered in the Iron Age. Iron was first used in South-Central and South-West Asia. Iron was picked over bronze because when it is blended with carbon, it becomes harder and durable. Iron can also hold a sharp edge better ...

Iron

Iron has been known since prehistoric times. However, the beginning of its widespread use came much later, because iron rarely occurs in a pure form in nature and its preparation from ores became possible only at a certain level of technology. The importance of iron in modern technology is determined not only by its wide distribution in nature, but rather by a combination of valuable properties. It is plastic, easily forged in cold and hot conditions, amenable to rolling, stamping and drawing processes. Iron has a property to dissolve carbon and other elements – this is the basis for the ...

Introduction: Interpersonal conflict reflects the differences, incompatibilities, or disagreements between individuals in a particular relationship whether between coworkers, friends, or romantic partners (Rahim, 2001). It is widely presumed that social support through interpersonal relationships provides a succor of refuge in times of overwhelming crisis or stress. In effect, interpersonal conflict has a logical outcome of increased stress. In fact, seeking emotional social support (e.g. emotions, ventilation), is one of the five most coping mechanism in handling stress (Carver, Scheier, & Weintraub, 1989). However, positive outcomes had also resulted from interpersonal conflict and stress (Katz & McNulty, 1994). Consequently, interpersonal conflicts may be associated with ...

Exoskeleton is a device designed to increase human muscle strength due to external skeleton. It replicates human biomechanics to scale up efforts in movements and can be integrated into a suit. Actual working models are now developed in Japan and the United States.
The first exoskeleton was co-developed by the General Electric and the United States military in the '60s, and was called Hardiman (Kong and Jeon, 2006). It could lift up to 110kg with a force applied at the lifting of 4.5 kg. However, it was impractical because of its considerable weight up to 680kg. The project was not successful. ...

Hip-hop is a youth subculture, consisting of several interconnected components: fashion, graffiti, art, DJs, rap, and breakdance. Other elements include beatboxing, hip hop fashion and slang. Hip-hop originally appeared in the South Bronx in the 1970s (12 November 1974, to be exact), and has become a part of youth culture in many countries around the world. Since the late 1990s the underground street culture with sharp social orientation, gradually became a part of the music industry, and by the middle of the first decade of this century, a subculture of hip-hop has become «fashionable» and «mainstream». However, despite this, there are plenty of ...

Peace that people enjoy nowadays uninterrupted is, of course, not a new phenomenon. However, what is interesting is that the humanity has lived only several hundred years without warring for whatever reason could bring large armies face-to-face in a lethal confrontation for questionable reasons. Besides soldiers, the brute force of conflicts, the main tools of war have always been weapons indicating the state of technological advancement of nations, being the litmus paper and the benchmarks of progress. Thousands years ago, there was no such concept as a long-lasting peace, and the weaponry was a lot more different than it currently is, being used ...

Abstract

Depression is known to influence an individual’s cognition and reaction. With this, studies were analyzed to come up a consistent assumptions and conclusions about how cognition and depression is connected. Cognitive Theories of Depression was discussed. The foundations of cognitive theories of depression was briefly explained, and later focused on studies by Aaron Beck, Dr. Albert Ellis and Martin Seligman. The main principles and assumptions of their works were explained as well as analyzed their objectives and proposals. Moreover, cognitive deficits in depressed individuals were discussed. Furthermore, it was explained how cognitive deficits develop, and the idea of memory ...

Steel is an alloy of another metal, iron. In addition, it contains carbon components. The carbon content of steel metal varies between 0.002% and 2.1% according to their weight. In fact, it is the carbon component in the steel metal that makes it harder than mere pure iron. As such, these carbon atoms make it hard for any dislocations to occur in the iron crystal lattice preventing the lattice from sliding past each other. Notably, steel is the metal that is most widely used for construction purposes, as well as the most recycled metal on earth. It ranges from ...

Introduction

Proper selection of the material and manufacturing process to be used for a given application is crucial to the success of the manufacturing process. Material selection should be based on material suitability and the possibility of modifying the material to make it suitable for the application while the selection of the manufacturing process should be based on the material selected, the shape required, dimensions of the item being manufactured and the cost of production. A product design specification (PDS) is a crucial element of design that outlines the design and operating requirements and, therefore, facilitates the selection of suitable materials. This ...
