What does the court mean when it says "Stare decisis is not an inexorable command; rather it is a principle of policy and not a mechanical formula of adherence to the latest decision"? Stare decisis is a Latin word that means to stand by what has already been decided. Therefore, in criminal law it is defined as the adherence of the current court system with the principles that has already been established by previous court decisions or rulings. In other words, it can be stated to be a principle of policy. Hence, it promotes reliance on the judicial ...

A magneto is small generator formed from a permanent magnet, which uses electricity to give outputs such as pulses of high voltage. A magneto has a transformer, switch and distributor, which give alternating current the direction to the plug that produces sparks. Timing in magneto is the interval in which the breaking point occurs after producing the sparks. Therefore, the purpose of magneto timing is to actualize high voltage used to produce sparks at the right time. It is achieved through the internal and external timing. Internal timing takes place mechanically on a bench. There are two adjustments in ...

The society that we are living in at the moment is characterized by different forms of behavior. This is nothing new as different people have seen it since time immemorial. Sociologists have also tried to do an observation and a study on the behavior in the society and they have come up with different conclusions. In the theory of Durkheim Emile; who was a French social scientist, the social cohesion of undifferentiated, small societies can be referred to as mechanical and of the societies differentiated by a division that is relatively complex in the division of labor can be ...

It is one of the ironies of history that the “old west” was actually the last area of the north American continent to be settled. By 1860, for example, San Francisco, California was a booming city of 56,802 persons making it the 15th largest city in the nation (San Francisco Population). Kansas City, meanwhile, had a population of 4,418 (U.S. Census Bureau). Denver, Colorado was already the “Queen City of the Plains” with a population of 4,749 (Population of Denver, CO). These three communities are important since Denver and Kansas City represent the western and eastern ...

Three phase induction motors

Introduction The three-phase induction machine is the most widely used among the rotating machines. An induction machine offers an almost constant speed within its normal operating range when operated off a constant-voltage, constant-frequency, and with the electric power source. The cost of purchasing these machines is very low, and they require little maintenance. However, speed control is difficult and very expensive. Therefore, the rotor current of the three phase induction motors is not induced by electrical connections, but rather the rotation of magnetic field.

Literature Review

Impact Mitigation

Intelligent locomotive bumper designs have been touted as possible life-savers for pedestrians. Paden, Kelly, Hines, Botham and Simms explored the feasibility of a life-saving locomotive bumper (103). There were several motivations behind their paper. Perhaps the most important one was the high number of pedestrians that were killed every year in train impacts. Between the years 2007 and 2012, about 10,950 non-suicide deaths were attributed to train impact on humans. Including suicide deaths on railroads, 28,800 pedestrians were killed during that 6-year period. Also, Paden et al., noted that passenger trains served densely populated areas ( ...

Introduction

How materials behave is dependent on various factors, some of which include their mechanical properties. When the material experiences various loading conditions, its behavior reflects its mechanical conditions as well as the effect of the loading conditions. When a material experiences various loading conditions, the material experiences either shear stress, tensile strength, or compressive strength. The tensile properties of a material relate to its ability support any axial loads to which it is subjected without rapturing (Department of Engineering. 2007). When a material is subjected to tensile stress, the deformation that occurs is in the form of elongation or ...

Introduction:

In addition to the physiological factors, there are a number of psychological factors that play a major role on musculoskeletal pain that can lead to disability. After the patient has healed from the physiological factors that led to the experience of pain, there are still fear avoidance beliefs that can take the form of chronic pain in the mind, so that the patient resists increases in physical activity levels. Ironically, the decision to reduce physical activity levels in response to this combination of physical pain and psychological fears keeps the back pain chronic, as the patient never overcomes the ...

Introduction

Until recently, genetic foods have become popular for their ability to address many production and quality issues faced by natural/organic farming methods. Genetically modified crops are those whose genetic makeup has been improved to enhance the level of nutrients, resistance to diseases, increase yields, adaptability to climatic factors, and reduce the time of production (Ronald & Adamchak, 2008). It is different from the conventional breeding because genetic modification allows introduction of genes from any organism (animal and plants) in altering crops whereas breeding allows transfer of genes across related species only. On the other hand, organic farming is a natural ...

1. The dogmas are laws and axioms that define a science and all the studies inside that science must follow. It is difficult for an investigator to challenge or dispute a law of axiom of natural science as biology, chemistry or physics; because the current scientific community follows the current dogmas of the natural sciences. In the best of cases, tens of years after the discovery or laws challenging other scientist and investigators must support the idea after the scientific community accept a change in the current dogmas.

Currently, the central dogmas of the natural sciences are:

a. All the pluricellular organisms are mechanical. The animals are considered ...

Complications of Removable Implant Supported Prostheses

Introduction The two main complications that result from removable implants are biological and mechanical/technical complications. There is need to assess and interpret data on the incidence of complications, both biological and technical with caution. Berglundh, Persson, and Klinge (2002), found that implant loss was the most common problem, while technical complications were observable in about 60-80% and biological complications – 40-60% of the studies they evaluated. According to Sadowsky (2007), there are no specifications on the length, distribution, and number of implants; however the suggestion for non-palatal coverage designs should be a minimum of 4 implants.

Research Paper

Introduction The social world is as complex as the physical world. Due to such complexity, sociologists have made considerable efforts to explain various social phenomena through different sociological theories. One of the major sociological theories is functionalism, which has its origins in the works of Herbert Spencer and Emile Durkheim. The functionalist theory explains how societies survive and maintain social stability. It also explores dysfunctional events like suicide. This paper argues that functionalism can provide a reasonable and accurate explanation of the phenomenon of suicide since social factors, like excessive social cohesion or the lack of it and extreme ...

Introduction

The concept of sustainable development was first introduced in 1987 by the United Nations as part of the Report of the World Commission on Environment and Development, in which it was stated that sustainable development implies “meeting the needs of the present without compromising the ability of future generations to meet their own needs” (United Nations General Assembly, 1987). The World Conservation Strategy published in 1980 served as prelude to the conception of this notion, as the UN recognized the importance of minimizing the impact of human activity over the earth’s ecosystems and adopting models inclined towards sustainability ...

[Class Title]

Introduction There is no limit to what human intellect can achieve. This mindset is particularly evident during the Renaissance; a period in European history wherein there was a significant ‘rebirth’ or revival of classical work. Scholars believe that the Renaissance started sometime in the 13th century and ended at the onset of the postmodern era in the late 16th century. During this period, Europeans became increasingly interested in the arts, architecture and science of ancient Greek and Rome. The significance of the Renaissance is that it ended the long period of cultural darkness that characterized the Middle ...

Introduction

The exchange of respiratory gas is limited by the capacity of the respiratory muscles to circulate air in the lung. Ventilation fails when muscles do not have the capacity to cope with the load brought by the mechanics of the pulmonary system. It is crucial to comprehend the mechanics of respiration/breathing not only for purposes of diagnosing how the system has failed and to offer the correct prescription for treatment of the failure, but to be capable of providing the most effectual temporary respiratory support through the use of a mechanical ventilator, as well. The first category explains the ...

In addition to the direct physical manifestation of swarm phenotype –increased length and number of flagella, swarm cells often produce wetting agent, usually a surface of some type, for instance, the surface in Serrtia (serrwettins) and Bacillus (surfcatin) (White, 2006). In both cases loss of surfactant dramatically decreases swearing proficiency in Bacillus as well as strains of E. Coli do not make surfactants, which is probably why they are such picky swimmers. Surfactants act mainly to maintain surface wetness, which in turn allows cells to swim in every shallow layer of fluid on the surface. Research findings indicate that ...
