Essays on Experiment

A beetroot was used to determine the changes that happen due to increase in temperature. A cylinder of beetroot was cut into 1 cm for 15 pieces and was left in distilled water to remove its excess dye. Five test tubes filled with 10 cmᵌ...

For this lecture, I arrived a bit late because of the inclement weather. However, I did not miss much since the lecturer began with a revision of where we left off from last session. The lecture continued with us being presented with the approach that...

In this article, the experiment is to determine methylmercury in human hair by capillary GC with electron capture detection. Hair is one of the main accumulation sites of mercury and can be used to examine methylmercury contamination in the human body. An analytical procedure was...

In this lab, we observed, “the ability of differing pigments in spinach to absorb and transmit different wavelengths of light” (packet). The results that we acquired were that there were three different pigments in the vegetable that we used. We found a dark green, lighter...

This experiment is carried out to observe the development of quail embryos within several days. The quail embryo usually develops and hatches in 20 to 21 days. We have conducted the experiment up until day 15, which it is consist of 16 eggs in total....

Experimental procedures Experiments were conducted to obtain B doped samples using same experimental setup of Figure ‎4 1 with replacing Phosphoric acid with Boric acid solution (2%). The dopant liquid was prepared by dissolving 2 gm of Boric Acid H3BO3 in 1000 gm of distillated...

There were many academic experiments performed to try and get an understanding of human nature. The way humans act, and what they do is a very strange thing. Human nature really refers to the patterns of behavior that are typical of our species or our...

Transfer Path Analysis (TPA) is a designation for the group experiment-based techniques to study transmission of mechanical vibrations. Over the period of time, applications of TPA increased a lot and used in mechanical industries for out of the box product testing. The main purpose of...

“ By now it is quite clear that this investigation could have given more promising results because the extent of Percent Error does signify and question the reliability of the data collected during this experiment. But, nonetheless, the reasons why these errors came to be...

Beginning in 1927 and running through 1932, the Hawthorne Studies took place at the Western Electric Company’s Chicago Plant, who employed mostly women who assembled telephone equipment. The number one objective of the Hawthorne Studies was to examine how different work conditions affected employee productivity....

The effects which cause growth and decay of the wave are ion inertia and a pressure gradient, respectively. The pressure gradient leads to diffusion, namely, is working to smooth out the density fluctuations. If left to its own, it therefore creates a decay of the...

These are the bioreactors specialized for the fermentation that can be carried out either by exposing to sunlight or artificial illumination. Since artificial illumination is expensive, only the out of door photobioreactors are preferred. Certain important compounds are produced by employing photobioreactor Ex, B-carotena asthaxanthin....

The aim of this experiment was to investigate how different concentration of sucrose effect on the rate of osmosis on cubes of potatoes This was done by using potato cubes cut out for the exactly same size 2 cm length 1cm width and 1cm height....

An emulsifier is a substance that stabilizes an emulsion. They make it possible to mix two oil and water-base components together. An emulsion is a combination of two liquids that would not normally mix. Emulsifiers are the chemicals that cause emulsions to happen. They also...

Abstract In this lab, the program Quartus was used. In both days of the lab, we were to implement simple combinational circuits. The first part of the lab was setting up the program. After that, we were to make VHD file. We were given the...

Introduction Watson and Rayner (1920) investigated classical conditioning, a behaviorist theory of learning. The researchers conditioned fear into little Albert and showed that fear can be learned. This research was ground-breaking as it demonstrated how phobias can be acquired at a young age. Although Albert...

Abstract A study was carried out, testing the effects of self affirmation on hedonic and eudaimonic well-being. Participants consisted of 540 undergraduate students (141 males and 399 females) from the university of Western Sydney, with their ages ranging from 17 to 71 years. Participants were...

Theory: Atmospheric temperature is a temperature of at different levels of earth’s atmosphere. It is controlled by many factors, including incoming solar radiation, humidity and altitude. In the earth’s atmosphere different greatly at different height relative to the earth’s surface. The coldest temperatures lie near...

Composites include a base material or matrix and additives to improve the properties of the matrix. Today, composite materials have attracted much attention in many industries such as aerospace, automotive and marine industries, due to their low weight, high strength to weight ratios, and high...
