Introduction5 Literature Review..6 Conclusion....11 References..12 Abstract Negative (opposing or intimidating) events arouse robust and speedy physiological, rational, emotive, and social reactions. This organization of the organism is accompanied by physical, cognitive, and interactive results that diminish, lessen, and even wipe out the influence of that incident. This array of mobilization-minimization seems to be bigger for undesirable events than for unbiased or positive happenings. Hypothetical explanations of this response form are reviewed in this paper. Further, it will give a verdict on whether negative bias has been helpful or harmful to the process of human evolution. It is established that ...

Summary Of Proposed Research

Global drought not only affects the world agriculture and economics, but interactively affects the phenotypic trait of plants across a different diversity gradient. Nevertheless, plants are able to adapt themselves to the drought environment by changing their phenotypic trait. From previous research at Jena Drought Experiment, in Germany, the results show that diversity not only has the capability to increase community’s resistance to drought, but also to increase community’s recovery ability after drought. On the other hand, the results show that the drought environment makes a strong selection on both, the plant phylogeny and functional trait. Yet, ...

Introduction

Spectrophotometry is one of the most common and efficient means of chemical analysis currently used in estimating the concentration of some chemicals. The technique exploits the radiation absorption property of various chemical substances in determining their concentrations. Spectrophotometry is based on Beer-Lambert Law. Beer-Lambert Law is the linear relationship between the absorbance and concentration of an absorbing species (Nair, 2010; Burrows et al., 2013). The mathematical expression of Beer-Lambert Law is shown in equation1 below: A=aλ*b*c Equation 1 In the equation 1 shown above, A represents the measured absorbance, a is the absorptivity coefficient which depends on ...

The data was collected through a Health Survey that was performed in 2011. The data was analysed using t-test, one-way ANOVA with Tukey HSD post hoc test, and the linear regression. The study found that there was no correlation between marital status and the body mass index. However, the effect of marital status on the body mass was statistically significant even though marital status accounted for 0.2% ...

The relationship between wealth and health (Wealth-health gradient)

Economists argue that wealth determines the health outcome of a person or the society. The World Health Organization (WHO) uses the idea of money to implement its health agendas especially in developing countries of Africa (Anonymous, 2008). Money determines the quality of health care offered to a person. Income acts as the driving force that helps people and societies overcome health disparities experienced by many minority groups. According to Woolf et al. (2015), the relationship between wealth and health forms a gradient that places people at different levels of the economic ladder depending on their wealth. People earning low ...

Water Resources

The Moscow city's location gives it access to Palouse River in Idaho as well as Paradise Creek whose upstream basins are the main water resources in the area. The Palouse River is from formation of the lava basins on both sides of the Moscow mountain that describes its high gradient at its youthful stage and thus flowing fast as it loses its height down the mountain. Just like most of the streams in active tectonic areas, the Palouse River has a straight channel considering the existence of alluvial fans as well. Regarding the fact that this stream has its ...

In the realm of physics, every motion in the universe is governed by a multitude of forces. From the smallest subatomic particle to the gigantic astronomical body, each particle follows a universal law of forces that determine how they interact with one another. Understanding how these forces work is essential in understanding how the natural world around us works, and then to subsequently apply that knowledge to develop the human race in general. Some forces are readily observable and felt by people around us; some are not. Three of the most prominent forces affecting our everyday lives are the ...

The cardiovascular system consists of the heart and blood vessels that get bifurcated further into veins, capillaries, and arteries. Lungs and airways make the most of the respiratory system; these, coupled with other structures help in the inhalation and exhalation process. Muscles are the other part of the system that helps the lungs to expand and contract in sync with inhalation and exhalation. Absorption starts in the body after the food is broken down into its building blocks. The process of absorption starts in the abdomen with the direct consumption of simple substances( e.g. water and alcohol) into the ...

Step 1: Story of Race

The rationalization of non-European people and some European population, such as the Irish served a primary purpose of differentiating individuals within a population. Individuals within a group set are different from the others. Thus, the concept of rationalization acts as a tool to bring out the different categories that are present in our population. Eugenics was an idea suggested by Plato that was inclined towards the sustenance and uprising of superior human beings with regards to their genetic traits. Plato suggested the practice of selective mating. This is where individuals with superior characteristics would be paired, and sterilization of ...

Abstract

The experiment involved the investigation of the young’s modulus of different beams made from different materials. The beams that were used for the test were steel, aluminum and timber. The experiment involved placing of the beams on the measurement machine shown below and addition of loads at the center of the beam. The loads were then varied across the beams while investigating the relationship that existed between the beams when different loads were added. The height, width, and the respective deflections were therefore recorded for analysis. The dial gauge was used to measure the deflection of the beam ...

DEFLECTION OF BEAMSIntroduction

Any kind of modern day construction makes use of a component called structural beam, or beam. A beam helps in adding strength of any design or structure. Generally manufactured using steel, wood, or concrete, it is commonly used for spanning any open element of a structure. In any design work based on iron, steel I beam is the most commonly used one. On the other hand, home-based constructions generally make use of wooden beams. When steel I beam is encased within concrete, it forms a concrete beam and is typically used in the construction of heavy structures, such as ...

Use of Fossil Fuels for Power Generation and the Need for Renewable Energy

According to Nelson (2011), more than 85% of the world’s energy consumption, which is estimated at 520 exajoules, is generated through the burning of fossil fuels such as petroleum, natural gas and coal (p.19). Electric power generation from non-renewable sources will, unequivocally, result in their exhaustion and creation of a major energy crisis. For this reason, it appears primordial to shift in a greater scale to alternate power generation, such as solar, wind, hydroelectric, etc. Amongst these, Sorensen (2011) explains that though hydroelectric power does represent one of the major forms of power generation, its growth is stagnant ...

Abstract

In this experiment, the young modulus of three beams was investigated these were steel, aluminum and timber. The beams were placed and the deflections values upon addition of various loads at the Centre of the beam taken. There was a variation of the loads across the beam to investigate thee relationship that existed between the loads, the span width, height, and deflections. Measurement of the deflection was therefore done through the dial gauge with three sets of measurements being taken and the average calculated. Different beams were used to enable elaborate comparison of the coefficient of elasticity. Measurement of ...

Abstract

The aim of this experiment was to determine the relationship between the Young’s Modulus and the deflection of a beam. Since different materials have different values of Young’s Modulus, the students selected three different materials for the experiment. In this case, the materials used include timber, aluminium, and steel. All the materials were identical in terms of the dimensions such as width and length. The each beam of the three materials was subjected to some magnitude of force at the centre and deflection measured. Data concerning the magnitude of load and the corresponding defection were then gathered ...

Abstract

The aim of the experiment was to determine the relationship between the diameter of a steel ball and its terminal velocity in glycerol. Four balls with different diameters were put in a transparent cylinder full of glycerol. The velocity of the ball was calculated based on the time taken for the ball to pass from one mark on the cylinder to another. The results showed that an increase in the diameter of the steel ball leads to an increase in terminal velocity. Besides, the results show that the larger the diameter of the steel ball is, the faster the ...

Introduction:

Historically, photovoltaic (PV) market in this country was dominated by residential PV application (Ted 23). Among the revolutions made by the then government of Japan was to invent and promote other renewable sources of energy (Paxson 201). This paradigm shift by the Japanese government has been motivated by the craving to put some environmental factors in check. Also, the energy demand not only in Japan but also all over the world has increased. This has reached a level where the existing energy sources are unable to meet the current market demand. This paper seek to address various concerns of ...

Introduction

Bend (flexure) testing is often done in springs as well in brittle materials whose behaviors of failure are linear like concrete, wood, plastic, glass and ceramics. Bend testing is suitable for evaluating the strength of brittle materials where the results of tensile tests aren’t easy to interpret due to the breaking of specimens around the gripping (Schoffstall, Charles, and Robert 234). In bend testing experiment, smooth rectangular specimens without notches are recommended under three or four point bend arrangements. Figure I below illustrates three point and four point bend arrangements respectively. Figure 1. Bend testing of a smooth ...

This experiment is about heat transfer in a fin based on Fourier’s law of heat conduction and Newton’s Law of Cooling. The latter states that the rate of heat loss of a body is proportional to the differences in temperature between the environment and the body. On the other hand, Fourier’s law of heat conduction states that the time of heat transfer through a material is usually directly proportional to the negative gradient of temperature and the area, at right angles to the gradient, through which the heat flows (Liehnhard, 23). The two laws will be ...

Modern astronomy

There were four main contributors to modern astronomy: Sir Isaac Newton, Johannes Kepler, Galileo Galilei, and Tycho Brahe. Brahe advocated for the new standards for having a more precise observation even though he did not personally believe in the view of heliocentric. All of his contributions were huge for astronomy because he was able to create new instruments along with being able to calibrate them. He would check the accuracy of his instruments on a regular basis so it helped him to revolutionize instruments for astronomy. Kepler was an assistant for Brahe until he died in 1601. This helped ...

Question 1

For succinate oxidation to fumarate there is yield of 2H+ and 2 electrons; however, the process of the reaction skips one step thereby leading to 2 ATP. The resulting FADH2 electrons skips the first stage of oxidative phosphorylation by moving into the electron transport chain located in CoQ. This can be illustrated as NADH -> CoQH2. Consequently, there is 2 ATP forming stages found in the electron chain from CoQ to O2 used in this course (Schwender et al, 50). Indifferent to the first scenario, oxidation of malate to produce oxaloacetate results to NADH, with production of 2H+ and ...

Introduction

According to the Human Rights Advocacy and the History of International Human Rights Standards, one of the earliest political wrangling in the area of human rights was the division of these rights into several categories: economic, community, and cultural rights. Nonetheless, the overall understanding is that rights, per se, must be understood as interdependent and indivisible. Under the 1948 Universal Declaration of Human Rights (UDHR), there is no classification for rights; in addition, the accord does not aggressively set to establish an ordered rights regime. The universality of human rights is the ...

Question 1

(i) Arturo generally looked at the yield curve basing his argument on economic grounds. According to him, the slope of the curve tends to have a positive relationship with the real GDP of U.S. This points out that when the yield curve has a positive slope, the rate of economic growth should be strong over the next four to six quarters. The opposite also applies i.e. when the yield curve is negatively sloped, growth would be low. Arturo went further in his analysis of the yield curve to see how a given change would affect the economy based on ...

Question 1

FAD is reduced to FADH2 in Succinate oxidation to fumarate through catalytic action of succinate dehydrogenase. The resulting FADH2 electrons skips the first stage of oxidative phosphorylation by moving into the electron transport chain located in CoQ. This can be illustrated as NADH -> CoQH2. Consequently, there is 2 ATP forming stages found in the electron chain from CoQ to O2 used in this course (Schwender et al, 50). Indifferent to the first scenario, oxidation of malate to produce oxaloacetate results to NADH consequently, the NADH produced electrons completes its movement in 3 ATP forming steps associated with chain ...

INVESTIGATING THE RESISTIVITY OF A WIRE

Electrical resistance is a physical quantity characterizing the properties of the conductor to interfere with the passage of electric current and voltage, which is equal to the ratio of the voltage at the end of the conductor to the current flowing through it (Brown, Forbes T., 2006, p. 43). The electrical resistivity is a physical value that characterizes the ability of a substance to prevent the passage of electric current. The resistance of an electrical circuit can be calculated, with the help of two equations below (Woan, G., 2010). R=VI

R – Resistance (ohms), V – Voltage (volts), I – Current (amps)

R=pLA p – Resistivity (ohm.m) L – Length (meters)

A – Cross-sectional area (meters2)

Maps can generally be described as representation of the real world through graphics. However, this representation is usually considered an abstraction of the real world phenomenon (Chorley and Peter, 48). This is mainly as a result of the fact that the universe is infinite and it is quite impossible to capture its entire complexities in a single source. Maps can be used to represent various issues for instance: The distribution of human population, temperatures and other aspects of the environment. In the case of representing the distribution of nature in an accurate manner the following maps can be used:

Cell Description and Shape Attributes

 Essential life molecules, which make up all living organisms, are bound together by a membrane to form a cell’s structural unit (Hand, 2018). The diverse cell shapes in eukaryotes and prokaryotes reveal each cell’s function. Each cell develops a form related to its function. For example, neurons contain extensions (axons and dendrites) that pass quick messages to the entire body (Alberts et al., 2015). Erythrocytes have a flexible shape to facilitate easy movement across capillaries. Pollen grains contain spikes for easy attachment to pollinating agents.

Zajacova (2006) researched the issue of impact of schooling on mortality, Riegle-Crumb and Humphries (2012) developed a study related bias of math teachers towards male and female students, the study of Martin (1998) concerned gender issues in preschools, Mihelich and Storrs (2003) suggested cultural and religious changes related gender outlook, Diprete and Buchmann (2006) considered value of education from male and female perspectives, Bobbitt-Zeher (2007) concerned the issues related success in education and its impact on future earnings from ...

There exist numerous mechanisms in which cultural diversity and working experience affect interpersonal communication between two individuals in a business setup. It is a logical fact that individuals in a business setup will exhibit numerous diversities with respect to culture. Evaluating the perceived impact of cultural differences on communication between, say two employees will necessitate an analysis of the major aspects of culture that affect communication (Sept, 1991, p. 17). It is important in this aspect to understand that both culture and communication are social aspects. Therefore, it is perceived that there will be a mix up in between the two aspects. Fundamentally, ...

Filters

Filters might not work in Internet explorer because it is not possible to mix images and gradient on one image. There are versions of internet explorer which do not support multiple backgrounds in a native manner. It is required that the mixture be done individually. Filters should be used on individual elements and not mixing the features and the properties together. One alternative to achieving this would be to have the image use the gradient and let the image have a <element>. This would have the image shadow as a background to the image. Another solution would be to change the ...

- Describe two features that make all enzymes catalysts.

Enzymes are catalysts that increase the rate of reaction between substances and remain unchanged in the reaction. Enzymes are vital to several bodily functions and make possible such processes like metabolism and catabolism. Two features that make enzymes catalysts is their ability to lower the activation energy and their inherent tendency to combine with coenzymes and cofactors. Activation energy is the minimum energy required to activate the molecules of reactants in order to initiate a chemical reaction. Some substrates have high activation energies that would need very high temperatures to activate ...

Three main layers of the interior of the Sun are convection zone, radiation zone and the core.The central part of the Sun with a radius of about 150-175 thousand km (ie, 20-25% of the radius of the Sun), in which are thermonuclear reactions, called a solar core. The density of material in the core is about 150 000 kg / m ³ (150 times higher than the density of water and ~ 6.6 times higher than the density of the densest metal on the Earth - osmium), and the temperature in the center of the core is over 14 million K.
