Introduction

The objective of this experiment is to study the effect of a solute on the freezing point of a solvent. When a solute is added to a pure solvent, the freezing point of the solvent is lowered as compared to its pure form. This decrease in freezing point of the solvent is known as “Freezing Point Depression”. A similar phenomenon occurs in the boiling of such solvents, but instead of decreasing, the boiling point is increased due to the addition of the solute. This phenomenon is known as “Boiling Point Elevation”. Such phenomena, including others, are known as colligative ...

Cell culture is an in-vitro technique of cultivating cells under controlled conditions and in sterile conditions. The technique was first developed by Ross Harrison in 1907. During the process of cell culture, the cells are detached from their tissue of origin and segregated from each other, either by mechanical or enzymatic means. The detached cells are then transferred before culturing them in cell culture plate or flask. The first generation of producing cell through this method is called primary cell culture. The cells from the primary culture are transferred to a new culture plate with a fresh medium to ...

Understanding the nature and connection between the mind and the body is less about finding one definite answer and more about the lasting implications that arise when probing into such a question. What does it mean to be a human being? Is humanness simply the body, or is it the desires and inclinations that make up our complex personalities? Are mind and soul one and the same? These questions arise in the Star Trek episode, “The Measure of a Man,” where Picard and Maddox view the same thing, Data, in two different ways. Maddox is initially guided by the ...

Abiotic factors which include climate are known to affect plant growth. Elevation which influences the climatic conditions can directly affect the tree height. The trees in higher elevation are thought to be shorter than trees in lower elevation because of the low temperatures which directly affects the height of trees. The experiment was done to ascertain tree height difference and to fulfil the deadline. The hypothesis for the experiment was that trees in lower elevation grow taller than trees at a higher elevation. The methodology for the experiment included measuring tree height in high and low elevations. Tree height ...

Abstract

The ecological settings in an ecosystem change from time to time. The changes in the ecological settings are brought about by a plethora of factors. Through evolution, the organisms that live in the ecosystem also change to adapt to the aforementioned ecological changes. The adaptation of the organisms to the ecological changes yields variations because different organisms and even organisms of the same species are exposed to the elements to different levels. Man has a significant role to play in the ecological changes. Through his economic activities, the effect on ecosystems has been both positive and negative. Urbanization as ...

Three replicate experiments were performed, and the experiment was performed with the serial dilutions. By measuring the optical density of the diluted solutions, the calibration line was obtained and the region with the linear dependence “concentration – optical density” was determined. The callibaraion line can be used for the practical tasks: for detecting ...

Introduction

Social discrimination is the unfair treatment or making a preference in courtesy of or against an individual in the society based on either class or group among others (Hogg, 2016). The society is characterized by differences in terms of wealth and power as well as status. The differences in such status and privileges lead to stratification in the society (Hogg, 2016). The inequality in the society brings uncalled for treatments and thus the discrimination. According to Karl Marx, the society is only composed of two groups of people. These include those who own the means of production and the ...

Introduction

Graphical Analysis is a straightforward program that enables the user to graph, analyze and find the relationship of variables easily (Guerrero 55). Data of the variables is entered from the computer keyboard, extracted from a disk saved file, or pasted from a clipboard. Graphical Analysis is as well a document creator, with the ability to compile different pages to a single document. In an experiment that involves analyzing the relationship between the density and mass of a substance, Graphical Analysis does it very well. The equation y=kx where y denotes the dependent variable, x denotes the independent variable, and ...

The British novelist, critic and essayist Virginia Stephen Woolf is considered one of the most authentic writers of England in the period between the First and the Second World Wars. Being discontented with the novels on the basis of the well-known, actual and apparent, Woolf went on her own experimental way. Walking along this path, the writer discovered a more internal, subjective interpretation of life experience, which is reflected in all of her creative works. It is also worth mentioning about the impact of such famous people such as Henry James, Marcel Proust and James Joyce on her work. ...

Introduction

The performance on a given task is affected by various factors. Distraction is one of the factors that has been hypothesized to affect task completion. Goodell, Cao and Schwaitzberg (2006) reported that cognitive distractions resulted in an increase in the time required to complete tasks by laparoscopic surgeons. Understanding the effect that distractions have on task performance is important various fields. In the academic field, the knowledge can be used to explain the performance of students during tests. It can help show what proportion of their performance is attributed to attention deficits resulting from distractions.

On Society and Gender Inequality in John vs. Jennifer

Central to the foundations of the governing principles that the Founding Fathers channeled while forming the Union was the desire for freedom and equality as the goals for the new government. Apparently, as opposed to the monarchical rule that the English Empire imposed on its American colonists, the latter supported democracy as the ideal form of governance for the masses. Case in point the peoples’ endorsement of the American Constitution that guaranteed a “[balance] of power” within the government and equality through “the nation’s size and diversity” (Foner 11). However, as evidenced by Congress’s agreement to maintain ...

Introduction

The book The Lucifer Effect by Philip Zimbardo argues that beneath any man lies some degree of evil, so detrimental if exposed under duress. The Lucifer Effect explains how good men can transform when exposed to stressful environments to commit heinous activities beyond imaginable moral magnitudes. In this regard, the author empirically explains the findings of the Stanford Prison Experiment (SPE) the processes involved in transforming good men into committing evil and heinous activities under duress and powerful situational forces. A comparison between the SPE findings and those of the Abu Ghraib prison in Iraq have strong correlations in ...

This experiment aims at studying the characteristics of titrations with the strength of different acids used in these titrations. This is done by drawing the titration curves of the different titrations that are carried out in this experiment and interpreting those curves. The units of measurement for this experiment are the standard units that are used in titrations. These are molarity (moles/liter) of substances while the quantities are measured in mL (milliliter).

Theory and Principles

Conductometry is a type of electroanalytical method in analytical chemistry. While other electroanalytical methods use equilibria or electrodes, conductometry is different and employs the conductance of materials ...

The character I chose for a reflective journal is John B. Watson. He is a representative of behaviorism and one of the most important persons in American psychology. It is essential to note that his views prevailed in American psychology for 50 years, and nowadays his ideas in altered form are still important. However, I am impressed by his points of view, behavioral, and radical experiments with a child. John B. Watson launched the behaviorist movement, rejected the philosophy of the past, the method of introspection, and mentioned that mental events were beyond the pale of scientific psychology. Unfortunately, ...

“If it has ‘science’ in its name, it ain’t (Minnick).” Those words were said to this writer by the smartest person he ever knew personally, a man with PhDs in Mathematics and Physics, a true scientist. He went on to explain that science, if it is science, can be reduced to mathematics and then can predict. “Science can generate electricity or flatten cities,” he said. The problem, of course, is that whenever one deals with the “soft sciences,” political science or economics (the dismal science) or sociology or history or any of the disciplines that are housed in ...

Introduction

The desire to conform to the norms is what makes the foundation of a civilized society. Social order, for instance, is a desired attribute that is founded on established written and unwritten rules that are being observed by most people within a society. Deviation from these established rules is considered as undesirable and people who deviate are considered as having abnormal qualities or malfunctioning (Merton, 2002, p. 672). There are instances, however, wherein some people are observed to deviate from the standard pattern of human behavior. This deviation has captured the interest of many social scientists and have been ...

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

Japan is reported to have the world’s third largest economy, which gives it an essential role in the global community. This calls for the need to understand the Japanese people’s self-concept and how they hold themselves up as individuals and as members of the society. It has been widely established that self-concept is far from being a static perception, rather it is a changeable system which is generally a result of an individual’s social relationships. It is observed that people normally hold a different perception of themselves as individuals, and as a social group member. Consequently, ...

In your own words, give the scientific definitions for ‘hypothesis’ and ‘theory.’ What is the difference between the two terms, and what is the difference between the scientific meaning and the way these words are commonly used? (6 points) Scientific hypothesis is a proposition aiming to explain some observations which are not explained by the contemporary scientific theory. To be scientific, hypothesis has to be testable through experiment and falsifiable. Scientific theory is a group of propositions explaining natural phenomena, which is supports by repeated scientific experimentation. Scientific theory is usually a group of scientific hypotheses which are repeatedly ...

Background of the Study

The problem of HIV and AIDS has become a global one in the short time since the identification of the virus. Although there is no vaccine to protect against the virus, knowledge and education are two powerful shields against infection—and it has become clear in recent years that impoverished women in the developing world are particularly heavily impacted by HIV transmission and development of AIDS (UNAIDS, 2016). The goal of finding a way to slow or completely halt the spread of HIV and the development of AIDS has been an epidemiological conundrum for many years. Promoting health and ...

The general hypothesis and one that has been adopted in this study is that coffee and particularly it major ingredient caffeine has significant positive influence on prevention of diabetes in humans. In this experiment, the researchers utilized a sample of eleven mice that had a genetic mutation for becoming diabetic. These mice were subjected to a diet of water (control group) and diluted coffee in the experimental group (Yamauchi et al., 2010). It was assumed that the experimental group would ...

Why aren't detectives more successful at solving crimes? Given their relative lack of success, how do you account for the "detective mystique"? In this essay, share some solutions to make solving crimes more effective. One of the major reasons why some detectives have difficulties in solving crime is because they lack the necessary skill, particularly the intellectual capacity to perform their job. One of the major challenges of law enforcement agents in solving crimes is the cleverness and cunning of criminals. Although there are many theories and procedures that aims to aid detectives in solving crimes, the successful ...

Abstract

The most crucial goal that has been targeted in all research studies in the past few years has been toward prevention of problems. The scientific method is a stringent and proven procedure, which can be used to determine the most probable evidence to back up an environmental phenomenon. The proposition is usually made in a cause-and-effect phenomenon. Such a proposition is known as a ‘hypothesis’. The method used for testing the hypothesis is termed ‘experimentation’. This procedure is comprised of five elementary and significant steps. The most salient aspect that renders the scientific methods most popular is the fact ...

Post-Stroke Depression

Stroke is amongst the leading causes of disability and mortality worldwide (Mitchell, 2016). In the United States (US) alone, an estimated 750 000 individuals are affected by new or recurrent stroke annually. Survivors of stroke frequently experience some neurological-linked disability like hemiparesis and aphasia that lead to a loss of function. An estimated 50% of stroke survivors additionally experience long-term disability like partial paralysis while 25-50% of stroke patients require help in performing activities of daily living (Byun, 2012). Post-stroke disability is linked to additional symptoms such as depression, fatigue, and sleep disturbances. These symptoms have been correlated with ...

An acid is a solution that loses hydrogen ions. Common household acids include vinegar and citrus fruit juice. In contrast, a base is a solution that gains hydrogen ions. Acidic substances often taste sour whereas bases taste bitter and feel slippery. Since the tasting or touching of acids and bases can be harmful to human health, Occupational Safety and Health Administration (OSHA, 2013) recommends the use of indicators to test for the acidity or alkalinity of substances. Typically, indicators such as litmus paper change color when exposed to acids or bases (Stanley et al., 2015). As such, the present ...

The study that was conducted in Oilfield of North Sea using the process of membranes of ultrafiltration (UF) and microfiltration (MF) indicated that the content of hydrocarbon decreased from 50 mg/l to 2 mg/l which recorded ...

Introduction

The term ‘social robot’ has become popular in the modern world and is almost being integrated into the modern day cultural constructs as usual. Lamers & Verbeek (2010) maintain that social technology is meant to invoke emotional attributes and to engage the human mind in a way that exceeds what is physical. Lamers & Verbeek (2010) argue that a robot is man’s effort at recreating his own self and it is with this semblance that the conceptualization of human-robot interaction has been captured. Dating back from the 18th century, inventors and scientists alike have been making numerous attempts at making ...

Plato held the belief, illustrated by his use of the analogy of the Cave, that we live in a world of illusions, with the true forms of the everyday objects which surround us being shrouded behind said illusions. According to his own philosophy, every object or concept (such as beauty or goodness) has a truth behind it; one which is perfect in every way. Furthering this idea, Plato believed that behind the world of illusions we live in which clouds our ability to see the true world, is a world which is populated by all those perfect forms of ...

Abstract

The primary concern of the sit-to-stand and walk training tasks, prominent in the health institutions target patients with knee problems or those recovering from surgical operations as a safe means of initiating rehabilitation or healing process. The use of gait initiation process sustains the efficiency with which the patients gain their mobility through the dynamic processes anchored for coordinating center of pressure and the body center of mass of the individual patient. The demonstration of the ability to sit, stand and walk is a clear expression of the positive progress made by patients in their recovery plans. The observable ...

In the face of modern science, researchers are facing a problem of the level to which the humanity of their approaches must extend. When it comes to solving ethical dilemmas, the vast majority of them tends to be concentrated on value placed on lives of humans as opposed to the value placed on lives of animals. There is a distinct separation between those who believe that animal drug testing should be banned, those who believe that it is often the main way of estimating the safety of drugs used, and those who choose to fall in-between and prefer finding ...

Liu, T., Moeller, S. K., Ode, S., & Robinson, M. D. (2013). Neuroticism as Distancing: Perceptual Sources of Evidence. Journal of Personality and Social Psychology, 104(5), 907-920.

Which perspective of personality did the authors take?

In both study 3 and 4, the researchers focus on how neuroticism (one of the five traits according to Eysenck) influences individuals’ perceptions of stimuli with positive or negative valence. A biological perspective is also evident in the fact that high neuroticism is dependent on an individual having an overactive sympathetic nervous system, thus a higher tendency for anxiety. The biological factor influences how each participant responds to the stimuli presented in ...

Forensic Science deals with investigations of suspects or criminals in crime scenes legally. In most cases, there are usually a lot of people involved in crime scenes. Some of them being innocent while some are the criminals. Also, there may be one criminal involved in an incidence. In Forensic Science, DNA is used to differentiate the individuals so that the criminal among them can be known. Additionally, DNA analysis is performed in the paternity testing. It enables the determination of a parent or parents of a child. DNA analysis is now being regarded as scientific evidence ("Application of forensic ...

Validity in Research Design

Validity in Quantitative Research Designs Validity refers to the degree to which physical evidence supports an experimental concept or conclusion. In statistics, it refers to the level of confidence that researchers hold on a particular causal effect of an experiment. The most common challenges to internal validity in the research design occur from the selection process of target population as well as the sample size (Yuan et al., 2009).In particular, the selection process in the article reflects only persons who have volunteered for the research. Ideally, this represents a threat to internal validity since the individuals used in ...

Fingerprint analysis is the oldest and common form of forensic evidence and unique of each individual. There are two types of finger prints –patent and latent. Patent fingerprints are easily visible to the naked eye and are caused by inks, blood, oil or paint ("A Simplified Guide To Fingerprint Analysis", 2017). Latent ones are not visible to the naked eye and are caused by skin secretions like oil and sweat (Daluz, n.d.). There are various ways of experimenting the latent fingerprints depending on the surface, material, temperature and chemicals. Here we will study the effect of different temperatures (hot ...

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 ...
