Human nutrition is associated with good health and well-being. Humans derive nutrients from food products such as fruits, vegetables, milk, and animal-based products. Nutrients should be taken in adequate quantities for proper functioning of the body. Diet provides vitamins, minerals, and all other vital components required for healthy living. Diet is one part of a healthy body while physical activity enhances growth, development, and stability to the body. People who have low nutrient intake are vulnerable to diseases and illnesses. Poor nutrition has also been associated with impaired physical and mental development (Kau, et al. 2011). Nutrition is the ...

Introduction

The cost of manufacturing ammonia using the Haber process plant constitutes the following components: the cost of energy, raw materials, equipment, labor and sparking substances (catalysts). Energy (gas or electricity) costs are incurred to maintain the temperature of the reaction. The Harber process is operated at very high temperatures, and pressures thus higher costs of energy are incurred. Some of the raw materials consumed in the Haber process such as nitrogen and hydrogen are recovered at the end of the process. The recovered materials are recycled back to the system to reduce the cost of raw materials. Starting and ...

INTRODUCTION

Economical and industrial development are two of the most important elements on the evolutional way for any country and nationality. However, it often happens so that people discover something new and hurl themselves into using it before making throughout estimations of potential risks and hazards. This is especially common if such newly discovered entity (an invention, or mineral, or a way to dig out minerals – this could be anything) is capable of making large sums of money: then there is no particular doubt of this entity becoming incredibly popular and exploited to the extent of being overused.

China's leading role on the world market is undeniable. Over the years, Chinese reforms transformed this country from a backward agrarian one into a leading industrial power, by industry of which the stability of many countries depends on. Another proof was the fact that since 2010, China has become the second largest economy in the world after the US, ahead of Japan, which had occupied this position for 42 years (Greenaway & Milner, 2010, p. 20). Today, China is the largest consumer, producer and exporter in the world. China encourages the discovery of new commercial and industrial enterprises, the implementation ...

Introduction: All most all metals are unstable when exposed to air. This is because of the tendency of the metal to be converted into its oxidized form on reaction with air. When compared to zinc, iron has a greater tendency to form oxidized form and thus has greater susceptibility to corrosion. The ability of metals to react with air varies and this determines their relative stability. As zinc is much stable when compared to iron, it is used to galvanizing iron pipe, thus preventing contact of iron with air and water that contains dissolved air. Brass is an alloy ...

Transcriptional regulation of gene expression

Gene expression in eukaryotic cells is regulated at transcriptional, post transcriptional and translational levels (Tomizawa,  Lekstrom-Himes, and Xanthopoulos 17). Transcriptional control is the primary means of regulating gene expression. Eukaryotic transcriptional control functions at three levels: modulation of the activities of activators and repressors; variations in chromatin structure; and effect of activators and repressors on assembly of initiation complexes (Lodish et al. 368). Regulation of transcription initiation is the most widespread form of gene control in eukaryotes. However, in some cases, transcription may be attenuated and regulated at subsequent steps, such as during or after the transcription process (Cooper ...

Although stable, this continental intraplate region has been associated with earthquakes in the past as it straddles the northeast-trending Lianhuashan Fault Zone. There are two major fault zones, which trends in the regional northeast ...

Trace elements refer to chemicals that form parts of important enzymes found in the body of a living organism occurring in minute amounts, less than 0.1% by volume (Anonymous, 2015). Trace elements are available in the natural environment and play a critical role in the survival of all living organism. Individual elements attract molecules from the environment and convert them to various products needed by the organism. Examples of trace elements are iron, copper, zinc, manganese, boron, molybdenum, iodine, cobalt among others. However, the following paper analyzes only three of these trace elements namely, copper, iron, and zinc.

Do blueberries and strawberries have similar levels of anthocyanins? How could you find out?

No, blueberries and strawberries have different levels of anthocyanins because anthocyanins are responsible for the colors associated with the fruits. (Berries and the Brain, n.d.) Since they have different colors, they have different levels of anthocyanins. Levels of anthocyanins in different fruits can be determined by chromatography or by using a spectrophotometer. The easiest way would be to separate the anthocyanins from other pigments in the fruits using different solvents, and then chromatographing the extracts. Finally, the amount and wavelength of light they absorb can be determined using a calorimeter which would help measure a number of anthocyanins in ...

Iron

Iron is a mineral that is abundant in plant foods, meat, seafood, and poultry. Green leafy vegetables have high levels of iron and are most suitable in cases of deficiency. Low levels of iron among young adult women can cause iron-deficient erythropoiesis (red blood cell production) and anemia (Harland et al., 2010, p. 325). These deficiencies can result in impaired immune and cognitive functions and can affect energy levels of an individual. Women of reproductive age usually experience menstruation on a regular basis. Heavy menstrual bleeding during this time increases the loss of iron, therefore, causing the deficiency.

Introduction

The tongue is comprised of small chemosensory receptors which detect different tastes such as sweet, sour or bitter. The information from the receptors is conveyed through the facial nerve, the glosspharyngeal nerve or the vagus nerve. The masking of the taste of the drugs is often done for several reasons. Key among these reasons is to avoid irritation of the stomach and the gut in addition to prevention of inactivation of the drug once it gets to the stomach.

The taste masking technologies can be grouped under three major categories which are: novel technologies, physical barriers, solid dispersion and ...

Introduction

Pollution of the environment is one of the oldest problems in the history of civilization. Man has long been considered the environment primarily as a source of resources, seeking to achieve independence from it, to improve the conditions of its existence. While population and the scale of production was small, and very extensive natural spaces, to achieve the goals we were willing to sacrifice some of the untouched nature, exactly as some degree of purity and water. This process in our relatively closed, not unlimited world cannot continue indefinitely. For example, it is estimated that each year for every person ...
