Q 1. The pioneering works of Ellis and Kinsey played a significant role in transforming the beliefs and practices relating to sex in the contemporary society.

Ellis and Kinsey’s groundbreaking studies inspired other sexologists such as William Masters and Virginia Johnson.

Kinsey developed a comprehensive interviewing and coding system that ensured confidentiality, and accuracy. These parameters still govern the current studies sex research studies.

Ellis and Kinsey’s studies opened the topic of sexuality for debate and academic study

Q 5. Concerns to keep in mind when doing experimental sexual research as discussed in “Chapter 3-Sex Research” include the following; Extraneous factors such as race, culture, gender and age of the respondents. Ethical concerns: The sex research should conform to the policies established by the government and other relevant ...

The history of food preservation begins with the understanding that the spoilage of food

begins from the moment it is harvested and left in open air. The earliest of methods used by man included freezing meat in the winter or drying certain foods under the sun. One of the ways by which man could move from one place to another while carrying an ample supply of food was by preserving it and preventing meats and other food stuff from spoiling. The need to kill and eat foods all at one time was prevented by the idea of food preservation. It is noted that different civilizations used various methods of preservation, mainly those which ...

Increasing concentrations of nitrogen in the environment, a phenomenon called as nitrogen saturation occurs when the inorganic nitrogen levels exceeds the demand by organisms and plants. Increased concentrations of nitrogen have detrimental impact on the air quality, owing to the oxidizing capacity of nitrogen oxides and their function in the formation of ozone layer . Excessive nitrogen deposition causes an increase in foliar nitrogen content, which subsequently leads to increase in tree growth . Other negative effects on the ecosystem are frost-hardiness in conifer trees in the presence of large doses of nitrogen. Excessive nitrogen concentrations may also lead to tree ...

The objective of this experiment was to prepare Beer-Lambert calibration curves for different forms of nitrogen and to determine the concentration of nitrate, nitrite, and ammonia ions in different water samples from the Biscayne Bay.

Introduction

Nitrogen is the most abundant element in the Earth atmosphere. In is not surprising that it is one of the most crucial elements not only to human life but all life on our planet. The chemistry of nitrogen is rather diverse because it can exist in different oxidation levels – from +3 to -5. Due to its large impact on the biosphere, the circulation of ...

Landfill Gases to Energy Production in Sampson Couty, North Carolina

Sampson County, North Carolina is a pre-dominantly an agricultural based county having million hogs on farms. Traditionally, farmers in the county relied on lagoons and other stone-aged land applications for treatment of animal waste, which released methane and other harmful landfill gases in the environment. It is considerable that methane alone is 20 times more potent than carbon dioxide in trapping heat into the environment, thus affecting the entire community around it. Another cause was the release of Nitrate through waste product accumulated in the ground level, that was potentially harming the water level in shallow wells and with ...

Sodium

Sodium is an element found in Group I of periodic table according to WebElements Periodic Table of the Elements (n.p), commonly known as the Alkali metals. It is a metal with silver-white color appearance. It is usually found in many different minerals like cryolite, zeolite and amphibole. The most common mineral where it is found is sodium chloride. Sodium is the sixth abundant element in found in earth’s crust. It has an atomic symbol of Na and an atomic number of 11. The atomic mass is 22.98977 and atomic radius is 186pm. Sodium is a very reactive metal. ...

Creatine is an amino acid. It is naturally occurring i.e. it is made in the body in the kidney, liver and pancreas. Creatine is obtained from foods such as meat and fish. In the body, creatine is converted to creatine phosphate and taken to reserves in the muscle. In the case of extreme intensity, short intervals of exercising such as weight lifting and sprinting it is used as an energy source. The storage form phosphocreatine is converted to the body's energy currency, ATP and used. The fact that it has this use has meant that athletes and body builders ...

Introduction:

Corrosion refers to the partial and gradual dissolution of materials used in water treatment and supply systems, pumps, pipes, tanks and valves. In most circumstances, almost all water is corrosive and this may lead to structural failure, water leaks, capacity losses and deterioration of the microbial and chemical water quality (WHO 2011). The pipes used in water distribution are made of different materials such as plastic, metals (galvanized steel, copper, lead and iron), and even concrete. Pipes made from concrete and plastic tend to be corrosion resistant. In piping systems, however, there are several water quality factors working singly ...

As early as elementary school, we are taught the water cycle. The simple cycle of evaporation that causes the clouds, the clouds rain on the land, the water is soaked up into the soil, lakes, and rivers only to travel back to the ocean and eventually become rain and snow again. It sounds like a simple process. However, much of California has been in drought for a while and everyone is suffering. Many cities ban the use of water outside, except on a specific day of the week. Neighbors turn each other in for water use. The rolling hills ...
