Introduction The Triaclyglyceral compounds refer to the group of lipids found in plants and animals; that are easily metabolized to acetyl coenzyme as they are twisters of glycerol as the main constituent of compounds. In most cases, the basic structures of most prevalent triaclyglycerals are not complex; but are composed...
Explaining the Sample The case study titled “Social Work Research: Program Evaluation” focused on assisting low-income families. Plummer et al. (2014) mention that analyzing case studies is efficient in developing skills and expertise in social work, and this discussion is used to improve competency in sampling techniques. The program evaluation...
Introduction The impact of biotechnology is being felt increasingly in modern days across several sectors and disciplines. Biotechnology can be defined as any technological application that makes use of biological systems or living things with an aim of making or altering products or given processes for specified purposes (Thieman &...
The scientific investigation of Earth has led to the formation of theories that explain how the planet as it is now changed over time. The archeological evidence, fossils, the placement of volcanoes, and glaciers serve as evidential proofs that provided the basis for the Plate Tectonics Theory. Importantly, the form...
Overview of Bayesian and frequentist approaches The research methods may be chosen by the researchers to influence the results of the investigation which can be later compared for different types of research methods. In this respect, the effectiveness of the method selected for the trial depends on the appropriateness of...
Many biostatisticians use statistical data analysis techniques to make sense of the data collected and provide responses to the issues identified in their research studies. However, it has been realized that data sets used to undertake the statistical analysis contain a multiplicity of outliers that may distort the statistical conclusions...
Executive Summary The analysis of sales data of five products (1-5) offers important information regarding their structure, appropriate models of the forecast, and prediction of demand. The attributes of product 1 indicated that it has a cyclical structure without seasonality and trend. Based on these attributes, SMA and SES were...
In a study, a film director sought to establish factors that influence the popularity of films. As a research design, the study examined the impact of gender and the type of film on psychological arousal. Gender and the type of film are two independent variables, whereas psychological arousal is the...
Benefits of using mixed methods research Many research studies adopt mixed methods approaches in their study designs that employ both quantitative and qualitative methods. Quantitative methods are concerned with collection and analysis of data (numbers) using statistical tests. On the other hand, qualitative methods are concerned with collection and analysis...
The work of a statistician is closely connected with possible risks of sampling error; therefore, it is always important to approach the study of statistical data wholly and objectively. Thanks to the theory, which includes several analytical tools of sample assessment, specialists can check whether the data obtained during the...
Introduction The stability of proteins determines the correlation between structure and function. Protein stability also plays a role in various properties such as aggregation, solubility, and protein-protein interactions. The stability of proteins is a necessary attribute in cells, as seen in various mechanisms such as unfolded-protein response machines, whose role...
Available literature demonstrates that malaria is a foremost public concern and a major cause of morbidity and mortality in the world’s most under-developed nations and some regions in developed nations (Ayele, Zewotir, & Mwambi, 2014). The occurrence of malaria, according to these authors, is related to deprived socioeconomic circumstances as...
Introduction It is accepted that the collection of research data should have a definite purpose. It is important to develop a research question matching the data to provide a meaningful result. A good research question is not just interesting but should be grounded in the analysis of evidence (Lipowski, 2008)....
Volcanoes have always been one of the central discussion matters in terms of geology and natural sciences in general. One of the reasons behind such interest is the fact that volcanoes have an extraordinary ability to deform over time, with the deformations being caused by various reasons such as subsurface...
Protection of human participants In an empirical study carried out by Jayadevappa, Schwartz, Chhatre, Wein and Malkowicz (2010), a total of 201 participants were recruited to take part in the survey. These were patients who had already been diagnosed with prostate cancer. Prior to treatment, the subjects were supposed to...
In 1996, the successful cloning of a sheep stirred a tremendous debate around the ethics of this practice and its implications for the future of humankind. Indeed, once, cloning from a single adult somatic cell without sexual reproduction used to only exist in science fiction. Before 1996, not once had...
Introduction The problem is stated unambiguously, it is easy to identify, and it builds on a cogent and persuasive argument for the new study. Additionally, the problem has significance for nursing as it addresses issues that nurses face in their day-to-day care activities. There is also a good match between...

Currency: The latest update was on July 24, 2020. The articles correspond to the advances, new surveys in the field of medical science. Relevance: The journal publishes original...
As before the creation of the first civilization and after its appearance, human beings always formed and united into groups and teams. In those days, it was a crucial principle of biological survival, and now it is a significant factor in the social and psychological life of the individual. Over...
Brain aneurism, also known as cerebral aneurism is a localized swelling condition of the brain’s blood vessels. The affected vessel is dilated at a localized point and may go unnoticed for a long time. People suffering from this condition experience symptoms such as sudden headaches and general discomfort. Severe aneurism...
Bias means deviations of outcome or conclusions from the reality or lack of internal authenticity in epidemiological studies. Selection, information and confounding are three types of biases (Recall bias can be a threat to Retrospective and Prospective Research Designs, 2011). Recall bias is a variety of information bias that threatens...
Introduction Hypothyroidism is one of the most common deficiency disorders among canines although it can not be easily diagnosed. It was first diagnosed in canines (dogs) in the 1970s (Volhard, & Volhard, 2011). It is mainly caused by an impairment of the thyroid gland responsible for the production and secretion...
Action Potential Action potential is simply a communication function in the nervous system. It takes across ion charged plasma membranes and is characterised by very fast reversals of voltage exchange. This is possible by the presence of voltage gated ionic channels that are found along the axon hence enable conduction...
The correlation study focuses on the assumption that there is some interrelation between two variables that cannot be controlled by the researcher. In other words, the correlation is not the causation. For example, the correlation study might suggest that there is an interrelation between public health and self-esteem, but it...
There are theories and ideas that are considered to be of major importance, as they provide an explanation of the way our world functions. Einstein’s Relativity, Steven Hawking’s Black Holes in Astronomy, and Darwin’s Origin of Species are a few examples of the ideas that, at some point, fundamentally changed...
Introduction There are a number of reasons defining the importance of correct evaluation of various mutagenic reactions in chemical compounds. Although many similar tests were designed, at the moment, the Ames test remains to be the most efficient for distinguishing mutagenic activities. Unlike several other options of assessing a mutagenic...
All knowledge is an illusion. While this declaration does not mean that we should support the supernatural or ignore knowledge, I trust that it is essential to accept some limitations of knowledge that relate to its source. Unless we consider some fundamental premises, we may be surprised to come across...
Whether triggered by negligence or caused by any other external factors, medical errors affect patients drastically, causing a vast variety of negative results, from minor ones, such as nausea, to lethal cases.
