This document is a project proposal for the development of starch-based hemostatic products. Acknowledgement. Much thanks to the project supervisor who offered guidance in every step of the development of this proposal. Developing starch based hemostatic products Project summary. Purpose: This proposal is envisioned to develop a hemostatic agent from purified plant starch. In this case, the product of the reaction should be developed by the formation of microporous hemosphere particles after etherification, esterification and crosslinking of glucose molecules to form ethyl propanetriol (glycerol-ether links (1-3 deoxy propanol)). The second intention of this study is to investigate the properties ...

Percentage of fat the athlete’s diet

Fat is a fundamental source of energy for the body. Importantly, fat provides approximately nine calories per gram which makes it a dense macronutrient. In strenuous athletic activities that last for about 6 hours, fats can offer about 60 to 70 percent of the energy required (Clifford & Maloney, 2011). Fats consumption in a diet of an athlete should be less than 30% of calories. Since athletes need a lot of energy, it is good to retain their fat intake at sufficient levels. However, depending on the activity, the athlete can decide to keep their fat intake at a minimum ...

Based on the initial symptoms, the patient most likely suffers from hypothyroidism or low thyroid hormone disorder. Further clinical tests and an examination of the family’s medical history reveals that the particular disorder could be Hashimoto’s disease; also called Hashimoto thyroiditis. Hashimoto thyroiditis is classified as an autoimmune disease. In autoimmune disease, one's immune system attacks the body’s tissue specifically the thyroid gland (Skugor & Wilder, 2006, p.2). By attacking the thyroid gland, the disease reduces the gland’s ability to produce thyroid hormones of substantial quantity. This condition leads to hypothyroidism. Thyroid hormone deficiency presents with ...

Abstract

The aim of the experiment was to determine the relationship between the diameter of a steel ball and its terminal velocity in glycerol. Four balls with different diameters were put in a transparent cylinder full of glycerol. The velocity of the ball was calculated based on the time taken for the ball to pass from one mark on the cylinder to another. The results showed that an increase in the diameter of the steel ball leads to an increase in terminal velocity. Besides, the results show that the larger the diameter of the steel ball is, the faster the ...

- Explain how enzymes are involved in processes such as the breakdown of fructose Enzymes are organic catalysts. In this context, organic denotes the matter in question is generated or is obtained from a living life form. The word Catalyst indicates a matter that has the aptitude to boost a chemical reaction’s rate, and is neither transformed nor damaged by the reaction that it speeds up.

Many chemical reactions occur but a slow rate that their progress would seem to be imperceptible at normally encountered environmental temperature. However, the enzymes are specific to certain functions. Generally, they may speed up a reaction, ...

Falling Ball Viscometer

- Objective The intent of this experiment is to find the dynamic viscosity of Glycerol by following falling ball viscometer method. Multiple steel spheres will be used to fall down the liquid and the time taken to fall a specific distance will be measured. - Background A body falling in a liquid is subjected to gravitational, buoyancy and drag forces which results in the achievement of a terminal velocity of the fall. According to Archimedes principle, we know that buoyant force is equal to weight of the displaced liquid. Implementing these principles, we get following equations, which result in ...

Falling Ball Viscometer

Objective: Purpose of the Falling Ball Viscometer experiment was to measure the viscosity of glycerin or glycerol by using falling ball viscometer technique.

Background:

When a body falls in a liquid under the force of gravity, it accelerates until weight of the body is balanced by the buoyancy force and drag force. Terminal velocity is gained by the body at this point. Viscosity of the liquid can be evaluated by measuring this terminal velocity of the body in the liquid. In this experiment a steel sphere was allowed to fall in glycerol and dynamic viscosity of glycerol was measured by using ...

Background

Type II diabetes mellitus is a metabolic disorder found in adults that involves high blood sugar (hyperglycemia) due to insulin resistance as well as an insufficient amount of insulin. Type II diabetes differs from Type I diabetes, which is characterized by a complete lack of insulin. Symptoms of Type II diabetes include thirst, frequent urination and hunger. Long term complications include heart disease, strokes, vision problems and kidney failure. Today, there are close to 300 million people in the world who have been diagnosed with type II diabetes, an increase of 10 fold over the past 30 years. This increase in ...

Harvey requires enough energy to perform. Consequently, he must consume enough calories to meet all his energy needs. The actual requirement for calorie intake depends on one’s level of fitness and bodyweight. In addition, the intensity, frequency, and duration of physical activity also greatly influence one’s actual energy requirement.

Carbohydrates

Given that Harvey’s daily workouts involve high-intensity activities, his calorie intake should comprise of between55 to 70 percent carbohydrates. In this case, 3 grams per pound of body weight would be appropriate. Based on this recommendation, Harvey should consume approximately 480 grams of carbohydrates per day in ...

Introduction

This analysis will focus on the excess intake of saturated fats and cardiovascular disease. The analysis is based on the report detailing my nutrient intake recorded for two days starting from September 4, 2014 to September 6, 2014. According to the analysis, my diet during the two-day period predisposes me to cardiovascular disease since it is high in saturated fats. According to the food guidelines given by USDA, saturated fats should contribute less than 10 percent of the total daily calories. However, my nutrient report indicates that saturated fats contribute 12 percent of my total daily calorie intake. Consequently, ...

Introduction

The term lipids is used to refer to a group of organic compounds that are naturally occurring and that are all soluble in non-organic solvents such as benzene , chloroform, acetone and ether but not soluble in water. The later characteristic means that lipids can also be defined as amphiphilic or hydrophobic small modules. This amphophilic nature of lipids essentially allows them to be able to form structures such as liposome’s, vesicles or membranes when subjected to aqueous environments. The biological lipids mainly originate from two major build-blocks or biochemical sub-units: isoprene and ketoacyl groups. Another distinct characteristic of lipids ...

Introduction

A balanced diet refers to the food intake, which incorporates all the dietary needs of an organism in the right proportions. This is unlike the adequate diet, which includes the energy that is sufficient energy for the need of an individual. A balanced diet, therefore, includes both sufficient energy as well as all the dietary requirements that are needed by an individual at the right proportion. The main components that make up a balanced diet include carbohydrate, proteins, vitamins, fats, dietary fiber, water and minerals. Carbohydrates as a source of nutrients in the body are usually broken down through ...

Red blood cells take approximately 120 days to be produced. The process of its production is called erythropoiesis and the place of production is myeloid tissue. For the formation of red blood cells, the haemocytoblast must be present. The existence of Multi-CSF causes the haemocytoblast to progress into progenitor cells. The progenitor cells, on the other hand, will form other cells. This cell may also develop into proerythroblast when EPO is present. Proerythroblast forms basophilic erythroblast which will in turn develop into polychromatophilic erythroblast, followed by normoblast which develops into reticulocyte which eventually becomes erythrocyte. All these developments must ...

1.0 introduction Thermoregulation is basically temperature regulation. It is a homeostatic process where by the internal temperature of an organism is kept constant within a specific range despite fluctuations in the external temperatures. It is important to note that all homeostatic systems use negative feedback mechanism. This implies that whenever there is a change in external or surrounding temperature of an organism, consequently a corrective mechanism is initiated within or without the organism to counter the change. Not all animals can maintain a constant body temperature; this is possible only for birds and mammals. Such animals are referred to as endotherms or commonly ...

In numerous ways, the human body can be regarded as chemical dispensation plant. In that, chemicals are ingested, processed via a variety of types of reactions, and then dispensed all over the body to be utilized instantaneously or accumulated for later utility. These chemicals utilized by the body can be separated into two wide groups: the macronutrients, those that we require frequently and in great quantities, and micronutrients, those that we require merely in small amounts. Among the macronutrients, there are three major classes necessary to living organisms: carbohydrates, fats, and proteins.

Simple Carbohydrates vs. complex carbohydrates

Carbohydrates are referred to as the major energy ...
