Question 1

The societal response to coastal changes caused by sand transportation has mostly been a moderate effort in harm mitigation. The erosion of shorelines and beaches tends to be seen as less of a cause for concern than higher-impact or episodic natural events, like earthquakes, volcanic eruptions, floods, and tornadoes (Dilley & Rasid, 1990). Sand transportation, also known as sediment transportation, is the movement of sand and other earthy particles (such as mud, clay, gravel, or boulders) along a sloping surface due to the motive force of gravity. This causes beaches to erode and shorelines to retreat. People have used several ...

Problem 1

Social and economic status influence criminal behavior. The independent variable of the problem is the state of one’s economic situation while the dependent variable is criminal behavior. The American Psychological Association (n.d) noted that an individual’s social and economic status affects physical and mental health, daily activities, and living areas. Besides, one’s financial abilities would influence levels of education and poverty and may predispose one to criminal behavior. At the same time, since poverty may have significant adverse effects on the mental health of the people, it follows that the individual may be susceptible to criminal ...

Police tactics are methods used to apprehend, target harden, or to suppress. The apprehension tactic is utilized when a person or “subject is being identified or captured. Generally identifying or capturing factors are dependent on geographical location, or temporal characteristics (Bruce, 2008). The target hardening tactic is used to the pattern of a perpetrator or the role that victim plays in a particular crime. Examples of target hardening tactics are clued surveillance cameras, alarms, etc. The last type of police tactic is suppression. Suppression tactics are predominantly used to elicit fear into the subject without the intention of capturing ...

The American Homeland Security Act contains a provision to arm pilots of commercial airlines and gives the deputy pilot the authority to use lethal force in protecting the flight deck against terrorism and other criminal threats. This act was later extended to include the cargo pilots as well. During the debate over the law, the opponents viewed such program as risky and expensive and outweighed the potential benefits suggested (Thurman 48). The proponents, on the other hand, saw the potential benefits of thwarting criminal acts outweighing the presumed risks associated with arming the pilots. In the wake of the September.11 ...

First of all, before even trying to look into the very dispute to be discussed in this paper, I’d like to state that in my opinion the following questions are the ones that anyone willing to debate has to be able to answer. What are the precise prescriptions of Islam and shariah laws regarding women’s garments? Are there any strict rules that are not ambivalent or ambiguous?

Why is it so that in different Muslim states women are granted different level of liberalism (if any at all) in what touches upon their clothes? For instance why ...

Objective

Purpose of this laboratory is to inspect the effect of precipitation hardening in Aluminum and steel alloys. Theory Hardness is a property of a material which delineates resistance to permanent or plastic deformation. For metals, hardness is generally defined as the resistance to indentation. One way to attain hardness is to look into the effect of precipitation hardening. This type of hardening helps to detain the yield strength in the material. There are four methods used to test hardness of a material: Rockwell, Brinell, Vickers, and Knoop. The Rockwell hardness test measures the depth of indentation, while the other three ...

Abstract

Microscopic analysis of materials is generally complex; hence engineers always look for alternative methods of analysis, by appropriate modelling. In specific, studying the damage of materials is important in almost every discipline of science/engineering/technology. Material damage includes the beginning, advancement and fracture of materials. The most important tool so far, used to analyze this damage, is called damage mechanics which relies heavily on continuum mechanics. It encompasses useful theories for the representation, modelling, and analysis of material damage. Broadly speaking, damage mechanics utilizes state variables to show the effects of damage. For instance, the variations in stiffness, and the ...

Introduction

Tensile testing is usually conducted to select a material for its application, quality control, and to forecast how the material is likely to react on deployment of different types of forces. The properties evaluated through the tensile test include the ultimate tensile strength, the maximum elongation, X-area reduction and so forth. These evaluations facilitate determination of such properties as Young’s Modulus, yield strength, Poisson’s ratio, and the characteristics of strain hardening [1. 2]. Tensile testing on glass fibre is, thus, performed to determine the quality of the material it contains, and to ascertain its suitability for various applications.

English bay beaches

Since there is no curvey wave line on the shoreline, we concluded that there are no big waves. The waves present were characteristic of a combination of both transverse and longitudinal motions. When we stood at the beaches and watched the waves, we guessed that the water moved towards the shore. However, after careful examination, we discovered that water was not piling up on the beach. When we watched carefully at some debris on the water, we noticed that a crest of a wave moved it towards the shore, but it moved back the same distance with the wave’s trough. ...

INTRODUCTION:

The concept of Cottrell atmosphere is important to many aspects of material sciences and engineering. This was first proposed by Cottrell and Bilby in 1949 to explain the interaction of solute carbon atoms with defects in steel. The Cottrell atmospheres occur under the interaction between the dislocations and impurities (alloying elements) in matrix metal. These defects, like a dislocation, produce long-range elastic stress fields that distort the interstitial lattice site around the defect in the matrix. These distorted lattice sites then provide lower energy sites for the solute carbon to occupy, thus relieving some of the stress field. This raises ...

Alloy steels are basically carbon steels to which other metal alloys have been added so as to improve properties significantly. Three alloying compounds which are used in steel include manganese, chromium and nickel. The percentage of manganese present in steels ranges between 0.3% and 1.5%. It reduces effects of impurities gathered during the production process. It also works as a hardening agent, improves toughness and strength, non-magnetic properties and causes self-hardening to prevent abrasion. Chromium ranges between 0.3% and 4%. Its purpose is to improve wear, scaling resistance and oxidation. It also improves hardness and reduces ductility. Nickel ranges between ...

In today’s world, the criminal justice system stands to benefit more from the deterrence of crime than in the actual handling of criminal cases. Lucky enough, crime specialists have a number of tools at their disposal to choose from. One of the ways to used to deter crime is through the use of criminology theories. This is inspired by the fact that criminology theories give an insight into deviant behaviour and the various reasons underlying criminal activities. Among all these theories, social disorganization theory is the most popular within the criminology circles. The social disorganization theory was born from a ...

Cardio-Respiratory Disease

Cardio-respiratory disease is an umbrella term used to describe various diseases of the cardio-respiratory system which make it impossible for the heart and lungs to supply enough blood and oxygen to the body during sustained physical exercise. Cardio-respiratory diseases are also termed as cardiovascular diseases due to the commonality of diseases affecting the heart and blood vessels. This essay describes cardio respiratory diseases in terms of etiology, predisposing and risk factors, disease diagnosis, treatment and the discharge criteria.

and Fast-Food Restaurants and Fast-Food Restaurants This study compares situational crime prevention (SCP) strategies against robberies of convenience stores with SCP strategies used against crimes committed in fast food restaurants in and found that crime control strategies used against convenience stores cannot be applied with success to prevent robberies in fast-food restaurants. In fact, many of the target-hardening strategies documented were shown to have no significant effect on the prevention of crime in either type of industry, and those that were found to be useful in one industry tended not to work on the other. Thus, SCP ...

Abortion is the termination of pregnancy from the uterus. The issue of abortion has become a conflict of interest due to the contention between the civil rights movement and women’s rights movement with each group having its own ideology to support its stand supporting or opposing the act (Sproul & Bailey, 2010). The emergency of two groups termed as the pro-life and the pro-choice, which argued on when does life begin and whose morals are adequate for the society led to the escalation of the conflict.

Hardening, according to Glasl’s escalation model is the first stage of a conflict ...
