Introduction According to Skoog, Holler and Crouch (2007, p.23) chromatography refers to the process of separating constituents of different chemicals that are in a sample for purposes of detection or individual use. There are different types of chromatography techniques. For example, the gas chromatography commonly referred to as the GC...
Introduction The experiment was conducted to determine the usage and purpose of spectrophotometer relative to Beer and Lambert’s law. Spectrophotometer is used in measuring the intensity of light absorption as described in Beer and Lambert’s law. In the experiment, Glucose and enzymes were provided and since glucose is not absorbent,...
Introduction Strawberries are a group of perennial plants which belong to the Rosaceae family. They thrive well in soil that has good drainage, is moderately acidic (pH range 5.0 to 6.0) and require plenty of sunshine grow. They are capable of viable fruit production for a period of up to...
Abstract One of the sources of dimethyl ether is methanol. This report analyzes the viability of manufacturing dimethyl ether from methanol by heating it and converting it to dimethyl ether and water. The report considers different costs of operation to calculate the profitability of a plant producing 100,000 tonnes annually....

The human body is a fantastic organism that continues to amaze scientists with the features of its device for many centuries. However, even the previously explored body parts are fraught with many amazing features. This essay aims to study the human’s muscle tissue both in general and at the molecular...
Definition Hydrates are inorganic and organic substances that contain water and are easily formed by less polarized molecules that would fit into a clathrate water cage. The water molecule is combined in a definite ratio as an essential part of the whole crystal constituting the substance. Abstract Natural gas hydrates...
The political economy of Brazil According to popular political scholars of the 19th century such as Karl Marx and Adam Smith, the political events of a country affect its economic performance. Consequently, a country could be wealthy in terms of natural resources but perform poorly due to bad governance. However,...
Introduction Gas chromatography (GC) is a technique used to separate volatile components of a complex mixture. The method employs a column made of a flow-through narrow tube in which a sample containing various chemical components passes in a gas stream. The gas stream in chromatography is referred to as a...
Due to excessive use in agriculture, organophosphorus (OP) pesticides are one of the most widely occurring pollutants in the environment. They inhibit acetylcholinesterase (AChE) activity and cause serious nerve problems in animals and humans, particularly affecting the nerve-muscle junction. Sensitive OP detection and monitoring of degradation are the two challenges...
Introduction Polymerase Chain Reaction (PCR) is a versatile and critical reaction in molecular biology. The reaction is a landmark in molecular biology because it has made it possible for scientists to study minute quantities of DNA material. PCR involves the amplification of minute quantities of DNA into large quantities for...
There has been a hot debate on factors that influence a person’s personality. According to Salles (2017), some experts believe that genetics plays an indispensable role in facilitating inherent-acquired behaviors, while others claim the environment contributes significantly to shaping an individual’s personality. The debate raises the question of the rationality...
Most Surprising Historical Account on Birth Practice The author of this book has presented the historical accounts of birth in such a way that it is not easy to single out the most surprising practice. Almost all the practices are surprising for the reader, as it is hard to believe...
Introduction Papaine is normally used in separating racemic mixtures with benzoylamino acids. Alternatively the separation can be done using derivatives of amino acids like valine and alanine. The product that is derived after the separation crystallizes with ease. Palarimetry is often used to test whether the resolution has completed successfully....
In the current world, significant theoretical shift in the link between scientific exploration and ethics has taken place. The time difference between ethical consideration and parallel scientific inventions is slowly vanishing. This simply means that ethics has set up its own cadence. This change has been unfalteringly led to the...
Introduction The human chorionic gonadotrophin (hCG) is a member of the heterodimeric glycoproteins hormones family which also includes the human follicle-stimulating hormone, the luteinizing hormone (LH), and the human thyroid-stimulating hormone (Dimiri and Kayisli 5). The subunit found in these hormones is identical but the b subunit varies from one...
Summary This article was posted by Sue White in 2013 to the ABC Environment (Australia) Website (White, 2013).

Streptomyces Bacteria: Overview Belonging to the actinomycete family (Aigle & Corre 2012), streptomyces bacteria have a very peculiar morphology (Jani et al. 2015). Among the key species that comprise the streptomyces bacteria population, Streptomyces coelicolor, Streptomyces ambofaciens (Laureti et al. 2011), Streptomyces lividans, Streptomyces albicans, Streptomyces griseus and Streptomyces plicatosporus...
Human genome refers to the information contained in human genes. The information is stored in DNA sequences within cell nuclei and mitochondria (Michal & Schomburg 2013; Veltman & Brunner 2012). Human diploid genomes are found in body cells that are not involved in sexual reproduction while human haploid genomes are...
