  • Gelatinization Of Sugar On Starch Essay

    A mathematical model was proposed describing the quantitative relationships between sugar, water and protein on the gelatinization of wheat starch following the heating in microwave for 20s as determined by differential scanning calorimetry. Sugar addition decreased the degree of gelatinization of starch due to the microwave heating. Sugar was found more effective in delaying gelatinization than the water and protein. In water-limited systems the effects of sugar and protein on the…

  • Bomb Calorimeter Experiment Essay

    calorimeter constant can be calculated, as well as the heat capacity of the system of the calorimeter. These various techniques are all put to use to calculate for unknown values that do not appear in a standard table or entry. It is the study of calorimetry that makes it all possible. Hence, in this experiment, a bomb calorimeter will be used to determine the change in energy and the change in enthalpy of naphthalene. These two values are the goal for the experiment and through the…

  • Wound Healing: A Case Study

    We will be looking specifically at the total calories and protein in relation to wound prevention and healing. Carbohydrates and fat are also essential in diet, but the biggest nutrition contributors to wound management are the total calories and protein. Micronutrients such as supplemental vitamins and minerals may be beneficial as well. We will also discuss these. Calories provide our bodies with energy during the hyper-metabolic and catabolic state which the body is in when a wound is…

  • Raloxifene Hydrochloride Investigation Report

    10.1 SUMMARY The aim of the present investigation was to formulate Raloxifene Hydrochloride Liquisolid compacts, with coadministration of a bioenhancer, for oral bioavailability enhancement. The reason for poor bioavailability (2%) of Raloxifene Hydrochloride is low solubility (100μg/mL) and high hepatic first pass metabolism. According to BCS, Raloxifene Hydrochloride is considered as Class II drug, lipophilic and highly permeable compound. Therefore, formulating Liquisolid Compacts bearing…

  • Energy Expenditure Essay

    "What are the energy requirements for this specific patient?" this is a frequently asked question of dieticians and doctors in the clinical setting. Resting energy expenditure (REE) is the largest component (~65-75%) of the total energy expenditure, which differs per individual [1, 2]. Variation of REE in individuals of the same age, sex and weight is related to body composition. Individuals with a higher fat-free mass (FFM) will have a higher REE [3]. Children and adolescents differ in…

  • Solubility Enhancement Essay

    The development of new drug discovery technologies like high throughput screening, combinatorial chemistry, etc. has led to the discovery of a large number drugs that are poorly water soluble.(1,2) Approximately 40% of the NCEs are poorly water soluble and has poor bioavailability.(3) The successful clinical use of these molecules requires the application of solubility enhancement based formulation approaches. Among the various solubility enhancement technique like use of cosolvents,…

  • Energy Expenditure Lab Report

    body which results in energy expenditure. There are several numbers of techniques for the assessment of physical activity related energy expend, the most valid technique to estimate this value at the definition of the physical activity is indirect calorimetry (Westerterp, 2013). Oxygen consumed during postexercise recovery period and during exercise above resting level contribute to calorie expenditure. The physiology of upperbody exercise and lower body exercise has been thoroughly researched…

  • Polypropylene Response Essay

    On February 6 of 2018, at 11:00 a.m. in room 1043 of Thomas Cole Research building, Sade Rhodes spoke about the characterization of lignin-coated cellulose nanocrystals (C-CNCs) as a reinforcing agent in polypropylene (PP) nanocomposites. The logistics of the seminar that was most enjoyable was when the speaker focused on the matter of Nanocelluloses. She provided a lot of information on this topic and I understand how it related to her topics in her research. However, the only part that I did…

  • Lefloxacin Cocrystals Lab Report

    Levofloxacin cocrystals were prepared by solvent evaporation method. The drug and co formers, stearic acid and sodium saccharin were physically mixed in varying ratios of 1:1, 1:3, 1:5, 1:7 and 1:1 and 2:1 respectively in a glass mortar and the mixtures were dissolved in ethanol as solvent for crystallization. The solvent evaporation was carried in rotary flash evaporator (Laborota 4000, Hiedolph) maintained at 40 ± 2ºC and speed of 30 rpm. The products obtained were dried in a desiccator and…
