Introduction

In recent decades, trends in diets tailored to promote weight loss have resulted in a significant increase in the intake of protein, particular in people with overweight and obesity issues. Accordingly, researchers have questioned the benefits or risks linked to the habitual consumption of “dietary protein in excess of recommended intakes” (Martin et al., 2005). In general, the primary concern has involved the possibility that diets rich in protein may increase hyperfiltration and, hence, exacerbate renal damage. Nevertheless, the potential link between protein-rich diets and renal damage has also been questioned due to an absence of adequate clinical evidence. ...

Solid dispersion can be defined as a cluster of solid creations made up of at least two distinguished components one being a hydrophobic drug and the other a hydrophilic matrix which can take any form depending on the crystalline or amorphous nature of the solids used (see figure 1). In the context of pharmaceuticals, this technology was developed to help improve the solubility and bioavailability of oral drugs. Studies have indicated that a score of patients prefers oral drugs for their simplicity in administration hence they show more compliance in comparison to other types of drugs administered in different ways. However, the functionality ...

1.0 Lab 1: Heating Value Measurements: Solid and Liquid Fuels with a Bomb Calorimeter 1.1 Introduction Measurements of heating values can be derived for both solid and liquid combustible fuels using an Oxygen Bomb Calorimeter. The calorimeter measures heat. Heat is not the same thing as temperature. The heat of combustion is called the calorific value. The calorific value is “:the number of heat units liberated by a unit mass of a sample when burned with oxygen in an enclosure of constant volume” (Introduction 2007). The experiment uses the 6100 Bomb Calorimeter. The definition of calorific value in a bomb calorimeter ...
