Dimethyl Ether (DME) is made by converting hydrocarbons which are first converted to methanol and then to DME (Molar 13). It can be made from other sources such as wood byproducts, household and crop waste, or from algae biomass. It’ chemical formula is CH3OCH3 and is considered a more clean...
Abstract Antibiotic resistance has become a public issue that is both costly and horrifying. The diverse studies undertaken have established this phenomenon is becoming hard to control due to what scientists define as mutation. Therefore, antibiotic resistance should be taken seriously. Also more appropriate measures should be put in place...
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...
Background Fourier Transform-Infrared Spectroscopy (FTIR) is an analytical method that employs two distinct yet depended techniques. Infrared spectroscopy entails use of the infrared region of the electromagnetic spectrum in identification and study of matter. A mathematically derived algorithm called the Fourier Transform is then used to convert the raw data...

Introduction The main aim of this paper is to address the rare subject that entails the inclusion of the Oman culture in English literature. Oman is one of the most conducive places to visit in the United Arab Emirates. The region has a rich history, culture and background. In addition,...
Introduction Biological systems contain a wide range of fatty acids in cell membranes and stored fat. In particular, the cell membrane of microbial organisms consists of a bilayer of glycerophospholipids in which the fatty acids are esterified to glycerol (Carlsson 1973, p.288). Microbial fatty acids are unique from one species...
Introduction Tomlin, Lowis and Read (1991) indicate that many people exhibit clinical signs that are associated with constipation, anal inflammation, hemorrhoids, diarrhea and irritable bowel syndrome. According to Cristtofaro, Mottu and Wuhrmann (1974), other patients suffer from anemia and nutrient mal-absorption which predisposes secondary infections and illnesses. These clinical signs...
The graph describes the connection between relative humidity and temperature as well as the variations in these two parameters at different times of the day. The overall relationships exhibited are that the relative humidity increases as temperature reduces and vice versa. The peak relative humidity is measured at 6 am,...
Introduction Background information An accurate assessment of the concentration of dyes in food and beverages forms an integral aspect of consumer safety. Mutagenic effects stemming from high levels of concentration lead to cancer development. The determination of the concentration of dyes through spectrophotometric analysis provides an accurate method. Objective The...
Reptiles are popular animals that can be easily identified by people due to their typical characteristics. For instance, snakes have always made human beings joining opposite sides of the discussion on whether they like them or not. To begin with, reptiles are a group of slithering animals that have a...
The Aim of the Experiment This paper presents an experiment that was conducted to determine the activity of amylase on starch at various pH levels. The main aim of this experiment was to determine the optimum pH level for action of enzyme amylase on starch. Introduction An enzyme is a...
Introduction In Patrick Williams’ work entitled, Gypsy World: The Silence of the Living and the Voices of the Dead, he was able to show how the Manus Gypsies of France navigate a hostile world. At first it seems that his anthropological study was focused on describing their traditions when it...
Introduction Business management employs various strategies to achieve results. The five steps strategy by Porter focus on outside factors like the strength/weaknesses of competitions. The resource based approach by Penrose employ the firm’s resource and capabilities to gain a competitive edge. Theories, on their part, explain why various approaches to...
Introduction Sugarcane is a fleshy, tall perennial grass crop that grows fast infertile tropical soils (Sheridan, 2000). Physical and climatic factors such as temperature, soil, rainfall, and other factors largely affect its growth (Sheridan, 2000). The crop’s origin can be traced to South Asia and Southeast Asia, where it was...
Introduction The Pan group of non human primates resembles the human beings the most. They are the chimpanzees of the Pan Troglodytes and the bonobo ape of the Pan Paniscus. Their sociosexual behaviors resemble hominoids. Their lives in the wild gave them special characteristics which were modified when they moved...
It is possible to say that the history of the emergence of Afghanistan and its physical location has become the prerequisites for the “troubles” that take place on the territory. Afghanistan emerged as a “buffer” state that separated the territories of interest of Russia and Britain (Blijde et al 265)....
The modern archaeology relies on a whole range of tools, methods, and techniques that help the scientists to evaluate the sites before the beginning of excavations. The sites of different kind can be analyzed in a variety of aspects such as their chemical composition, the kinds of objects situated under...
All body cells are able to display a membrane potential that is defined as the separation of positive and negative charges of a membrane that promotes the distribution of different chemicals (Sherwood, 2011). Communication is one of the main functions of the cells in the nervous system that is possible...
Introduction Wildlife is always deemed to be of great significance economically, ecologically, environmentally as well as culturally. It includes a wide range of species from amphibians, insects, birds to mammals. Thus, there is no doubt that there are some organisms that are native while others were introduced or re-introduced to...
According to Robert M. Sapolsky, human beings feel that they are unique, unlike other species. This has been questioned by studies that have been done on other primates. Theodosius Dobzhansky, an evolutionary biologist, viewed that all species are unique. According to him, humans are unique; thus, they feel more proud...
Nowadays, people strive to improve the quality of life, focus on higher accomplishments, and try to find new ways to overcome such social problems as diseases and hunger. In this context, genetic engineering seems to be the potential to improve the quality of life because of creating new and improved...
Tomatoes as Goods Brought from the New World to the Old World The New World has had a rather significant impact on crops worldwide. Some of these contributions include maize, peanuts, avocado, cassava, and tomatoes (McNeill, 4). The latter crops originate from western South America and Central America. Tomatoes were...
Problem Statement This investigation aimed to apply Hess’s Law to estimate the enthalpy change of three chemical equations by calculating the heat transferred in a calorimeter. The objective was to determine the final reaction’s enthalpy change reasonably and confirm the applicability of Hess’s Law. Hypothesis Statement Hess’s Law is applied...
Introduction Scientific discovery is a product of communication, politics, economics, and people’s unique personalities. The case of James Watson and Francis Crick finding the double-helix of the DNA structure is no exception.
