Science Essays

So, we are concerned with research carried out by making effective use of existing quantitative data. That is, whereas in primary research both data collection and analysis are used, in secondary research, “creative analytic techniques [are applied] to data that have been amassed by others” (Kiecolt, 1985).

Clay slopes have undergone changes that are either short-term or long-term in nature. However, it is quite difficult to distinguish between short-term and long-term stability. It certainly depends on the geologist, soil scientist, or engineer’s subjectivity. Long–term stability could be ten years or even more.

To test for the hypothesis H0:  = 100 Vs H1:   100 using this confidence interval. Since the 95% confidence interval contains the value 100, we have insufficient evidence to reject H0 at a 5% significance level. We can conclude that the population means is  = 100. As the population variance is unknown, we have to assume that the sample means follow a t-distribution. 

Analysis of protein structures and functions help in understanding the exact relationships between the proteins and in identifying protein families and features. The data obtained is organized in such a way so as to access the already existing information on proteins, in this case, and develop tools and resources to analyze the data.

In case the person uses pressure, it means that someone is forced to do definite things, which we wouldn’t like to do. The person is forced to do these things because it would help keep up relations with people that are important for him for this or that reason. This may occur in various circumstances when peer pressure is used by relatives, etc.

The pollution can be biological, such as an unwanted bacteria and parasites. It may be a chemical which is known to cause cancer which has been discharged from an industrial waste site. Water can become polluted from agricultural runoff when toxic herbicides and pesticides mix with groundcover water and enters rivers and lakes.

The order of progression is worked out in systematic follow-up procedures independently from home. The reports are planned to present in precise but easy to comprehend language with identical headings. The resources of referring the medical journals and other theories in the application are expected to denote with brief relevance with the study.

Ecotourism has been suggested under the broad category of nature-based tourism wherein increasing numbers of tourists can be accommodated in an intrinsic natural environmental tourism experience at a minimum and reasonable cost. Ecotourism can be relatively defined according to the interpretation of the reader.

А mixed methodologicаl аpproаch wаs employed in this study. The primаry method wаs а quаlitаtive аnаlysis (content аnаlysis) of dаtа collected through personаl interviews. А meаsuring instrument wаs developed for this purpose. It wаs bаsed on the literаture review, three interviews with teаchers аnd the results from а quаntities аnаlysis of surveys.

Cell phones, radio, television, MP3 players, and optical disks are all examples of communicating information via images or sound (Wikipedia, 2004). The creation of the Internet has also made a wealth of information available to those who have access to a computer. Although it appears to be a modern-day convenience, the Internet has its drawbacks as well.

There is a numerous debate raging around global warming (GW) – from its meaning to the climate scientists and its intended meaning to the non-scientists, to its nature as an issue whether spiritual, political, or economic, to its supposed appropriate terms, to its perceived effects on tsunamis.

Studies have compared patients undergoing tracheotomy vs those not undergoing tracheotomy, and patients undergoing early tracheotomy vs those undergoing late tracheotomy.

The industrialization of the European nations has provided several examples of mechanisms underlying innovation in time and space. How this has impacted or intruded into the social fabric, and govern the interactions and correlations in the 20th-century society thereby bringing about changes in every nation, make an interesting study.

On the task to design and use a questionnaire to collect data comprised of open and closed questions, the author offers a questionnaire to collect data about left-handedness as a solution. It requires ticking the appropriate box with an answer, where the first box means that you are right-handed, and the second box - that you are left-handed.

They are the footprint of understanding the origins of space and time.  Scientists have been in the process of unraveling these mysteries for centuries.  To understand the development of POPULATION III, first stars, first an understanding of the basis of the formation of the universe is required.

For a dodecahedron, 3-edge coloring assigns colors to different edges of the dodecahedron. Proper 3-edge coloring is done in a way that ensures that none of the vertexes of the dodecahedron has 2 edges that have the same color leaving it. Proper 3-edge coloring entails that no 2 edges in the same vertex can be of the same color.

It is characterized by the odor of rotten eggs. Dissolved H2S gas reacts with iron from tubulars, valves, and system equipment to form iron sulfide. Iron sulfide is typified by "black water" seen in many oilfields. H2S eats away at the iron source, causing failures and leaks in flow lines, valves and process equipment.

Rusting or the formation of rust is also referred to as corrosion in metals or more commonly in iron materials. It is a chemical reaction that occurs on the surfaces of these materials and is characterized by the production of fine particles with distinct discolouration, more commonly in a brown or brick red hue.

X-rays are electromagnetic waves lying between UV radiation and γ-rays. They were discovered by a German physicist, Wilhelm Röntgen, and have wavelength 0.01-10.0 nm and a frequency of 30-30,000 1015 Hz). The main physical properties of X-rays could be described by the experiments where beams of x-ray photons interact with matter.

We have a two-tailed test and an alpha level of .05. Notice the research hypothesis is framed in the direction that we should expect, an improvement in scoring. Nevertheless, we will assess the hypothesis using a two-tailed test. So according to the given conditions we state tithe hat null hypothesis and alternative hypothesis will be.

In the prevailing field of men, women started realizing developmental biology requirements of more women than in any other field. They proposed certain reasons to it out of which one was the reaction towards the dominating attitude of men. Therefore commenced a new biological era in which men and women were more or less considered alike in their dedications towards biology.

The exact determination of HIV and HBV behavior upon contact with previously healthy cells is crucial to the formulation of an effective medical response. One approach practiced by scientists and researchers is to model in vitro in the hope of determining changes in gene expression for the formulation of candidate vaccine pathogens.

Intense storms and rainfalls occur on Latin American countries due to climatic changes. Growing population, commerce, and industrialization are responsible for pushing back these rainforests. The impact of climate change and environmental degradation can be seen from the drought in the Amazon to floods in Haiti.

Different soils such as sandy soils, soils with clay and silty soils have different levels of acidity, alkalinity, solubility and capability to hold or release nutrients. Soils are basically a mixture of minerals and organic materials. The soil properties such as color, texture and organic content may differ as we go deep.

Breakwaters are used extensively along coastlines all over the Earth and those that can allow wave overtopping without significant damage to effective structures and, thus, to properties and life they shelter are considered of eminent construction. Wave overtopping is a violent natural phenomenon that causes serious damage to protecting structures and life and property along coastlines (Shao, 2006).

In fact, for some organ transplants it is going to be possible sooner than others, although science still has a ways to go and it has to have FDA approval and all ethical considerations made beforehand. A cloned organ would work just as substantially as a naturally formed one due to the possible ways of cell regeneration that scientists are coming up with.

Smoking is likely to raise blood cholesterol levels. In addition, the proportion of high-density lipoprotein to low-density lipoprotein is likely to be lesser in smokers compared to non-smokers. Smoking also increases the levels of fibrinogen and increases platelet production which makes the blood thick. 

Success or failure of any social research directly depends upon the method chosen. Consequently, in order to choose the most appropriate method of collecting information the researcher must be aware of the peculiarities, advantages and disadvantages of each method applicable to the realm he/she works in.

The radical concept of the space elevator seems to overcome that - it combines the dual quest of scientific expedition and the search for a viable foreign zone, capable of habitat, with physical proximity and connectivity to earth. The space elevator is conceptualised as a vessel which facilitates transport from any celestial body into the space.

A group of marine vertebrates belonging to the order cetaceans has since been men’s inspiration to be passionate with the natural world of the deep.  Most people believed that cannibalizing members of such a group of marine mammals is a taboo.  But, for some, catching, butchering, and selling this marine mammal is profitable at the least cost. 

This is particularly important in circumstances where the process of aging injury or disease threatens movement and function. It is a great majority of people indeed experience lies with movement. In this relation, therapeutic muscle stretching has had known positive roles in inducing muscle flexibility (Ghaffarinejad et al., 2007).

Although in the early days it was believed that there could be no life at the bottom of the sea, a steady production of energy deep down at the ocean floor has led to a thriving benthic community which may however be affected by environmental changes. Investigation of benthic communities is done by deep-sea diving and obtaining samples of such organisms.

Though these mathematical data types don’t represent the computer notation, they help determine how a particular system will behave. The Z notation also allows for the disintegration of a given specification into schemas; this helps in presenting the code piecewise. Each piece can then be described informally with a commentary.

Without the fees that they collect, these organizations will effectively cease to exist. A functionalist approach to the analysis of the necessity of these services however, reveals that these changes will not only affect the students, but the community as a whole.

The first group of White individuals was subjected to the recognition test. Each took the turn of recognizing which two pictures (1 white face and 1 black face) belong to one person. The speed of recognition was recorded accordingly in terms of time in minutes.

According to Bhabha, hybridity is the process by which the colonial governing authority tries to interpret the identity of the colonized using traditional structure, but then do not succeed in producing something familiar but new. Bhabha theorizes that a new hybrid identity or subject-position appears from the interaction of elements of the colonizer and colonized twisting authenticity of any essentialist cultural identity.

Cloning is an artificial creation. It is the job of God being exercised by scientists in an artificial atmosphere. It can be generally described as the production of one or more individual plants or animals (whole or in part) that are genetically identical to an original plant or animal (prototype).

May it be the instance of the challenge put forth by Flemish physician Jean Baptist Von Helmont of ensuring that like is compared with like in the case of people suffering from fevers, pleurisies without bloodletting in the 1700s or Amberson flipping a coin for unbiased allocation for assigning treatment in the Tuberculosis trial in 1938.

The author argued that an economy using exhaustible resources can still maintain high standards of living; technological progress was one of the factors that would help achieve high levels of technological growth and also the existence of capital accumulation. He expressed the aggregate production function using the Cobb Douglas function.

The advent of the human cloning technology in the fields of genetics became the hallmark of scientific achievement in the previous and the present century. Although the technology is not yet perfected, many have placed high hopes in this advancement in the field of medicine as cloning could be used to treat genetically related diseases.

Ideas of the supernatural and witchcraft are both reasonable and have a social meaning in the context of the community in which they take place. Comprehending the social meaning in the social context of magic is based on understanding the meaning of the supernatural and witchcraft. Edward Evans-Pritchard researched a tribe of African people.  

Again, fatty acids, during the process of fatty acid catabolism, the fatty acids are broken down into both mitochondria and peroxisomes. The result of the process of beta-oxidation or fatty acid breakdown is the generating of Acetyl-CoA that happens to be the entry molecule for the Krebs cycle.  

However, what has been elusive is how these chemicals exert their influence on the reproductive and developmental process of wildlife animals (CLS, 1999; Colborn, 1999). However, recent studies have shown that the reproductive and developmental anomalies caused by these chemical are induced by their ability/capacity to disrupt, mimic or interfere with the endocrine system.

This benefit of SEM is seen particularly in the light of multicollinearity. Another important advantage of SEM involves the exploitation of confirmatory factor analysis. This advantageresresultsn a rauction in the measurement error by making use of multiple indicators per latent variable.

This is a result of having a large sample size. As the sample size increases, the difference between the two intervals is also expected to significantly increase, resulting to large errors. In this test, we assume that the sample standard deviation approximates that of the population without any significant statistical difference.

Proponents and opponents abound in the same manner as the pros and cons proliferate with deep and urging intensity.  We must take a stand thinking over all the possible aspects involved in this controversy.  At the end of the road, all of us will be winners in this debate as we are growing up in wisdom.

Besides, the authors tried to determine which exactly components of goal-directed behavior were affected. The experiment was aimed at achieving more precise results because the course of the experiments made it possible to keep dopamine neurons in DD mice intact that enabled control of the mice's ability to restore endogenous dopamine signaling.

Since the Pitot-static tube cannot measure the local velocity at a point because P0 and P are not measured in the same places, the experiment has used a smaller pitot-static tube to reduce the error. However, in this experiment, the error can be considered negligible. A fan supplies air to a nozzle, which can provide a circular uniform jet of air. 

In regards to cinema and screens it is noted that screens increased while cinema sites tapered off and admissions price index increased with screens. There is a positive correlation between admissions and cinema sites as well as screens with the same correlative results for gross box office takings.

That is, it is not merely fixed to sexuality differences. Gender is applied to the activities of both men and women. Thus masculinity or femininity is associated with social phenomena in relation to both men and women. Despite their vigor, power, physical strength and many manly qualities, men are not easily satisfied in their inner self.
