Ashurst, Ian C. "Physicochemical characteristics of chlorofluorohydrocarbon based inhalation aerosols." Thesis, Aston University, 1985. http://publications.aston.ac.uk/12546/.

Full text

Abstract:

The aim of this work was to gain a better understanding of the physiochemical factors which affect the formulation of suspension inhalation aerosols. This has been attempted by applying the principles of colloid science to aerosol formulation. Both a drug system and a model colloid system have been used. The adsorption of six nonionic and cationic surfactants onto Spherisorb has been investigated. The results were analysed by calculating the area occupied by one adsorbed molecule at the surface and by comparing these values for each surfactant. The amount of each surfactant adsorbed was correl

Abstract:

Made-in-transit (MIT) is a supply chain concept for the complete or partial manufacturing or production of perishable foods while being transported to the market. Fermented foods like yogurt are ideally suited for the MIT concept, due to the fermentation period required to produce it. The period required to transport the product from the manufacturing facility to the market should coincide with the time required for the fermentation process to be completed. A 33 factorial design was carried out looking at the fermentation temperature (25°C, 30°C, and 35°C), apple fiber concentration (0.5%, 1.0

Abstract:

Despite its extremely low solubility in water, fullerite C₆₀ can form colloidally stable aqueous suspensions containing nanoscale C₆₀ particles (nC₆₀) when it is subject to contact with water. nC₆₀ is the primary fullerene form following its release to the environment. The aim of the present study was to provide fundamental insights into the properties and environmental impacts of nC₆₀. nC₆₀ suspensions containing negatively charged and heterogeneous nanoparticles were produced via extended mixing in the presence and absence of citrate and other carboxylates.

Abstract:

Epithermal deposits include a broad range of precious metal, base metal, mercury, and stibnite deposits. These deposits exhibit a low temperature of formation (180-280°C) at pressures of less than a few hundred bars (equivalent to depths of 1.5 - 2.0lkm). Epithermal gold deposits are the product of large-scale hydrothermal systems which mostly occur in convergent plate margin settings. Associated volcanism is largely of andesitic arc (calcalkaline to alkaline), or rhyolitic back-arc type. Porphyry Cu-Mo-Au deposits form deeper in the same systems.

The objective of this research was to systematically study the effect of processing conditions on crystallization behavior and destabilization mechanisms of oil-in-water (o/w) emulsions. The effects of oil content (20 and 40 wt %); crystallization temperature (Tc = 10, 5, 0, -5, -10 °C); homogenization conditions, such as high shear (HS), very low pressure homogenization (VLPH), and high pressure homogenization (HPH); and cooling rate (0.2 and 30 °C/min) on both thermal behavior and destabilization mechanisms were analyzed. Docosahexaenoic acid (DHA) was added to VLPH emulsions and its effect

Abstract:

Accurate determination of the in vitro kinetic parameters Km (Michaelis constant) and Ki (inhibition constant) is critical for the quantitative prediction of in vivo drug clearance and the magnitude of inhibitory drug interactions. A cause of inaccuracy in vitro arises from the assumption that all drug added to an incubation mixture is available for metabolism or inhibition. Many drugs bind non-specifically to the membrane of the in vitro enzyme source. The aims of this thesis were to: 1) investigate the comparative importance of lipophilicity (as log P), and pKa as determinants of the non-sp

The aim of this study was to design injectable hydrogels with tunable physiochemical properties for musculoskeletal tissue regeneration. Elastin based hydrogels represent high potential for tissue regeneration due to their remarkable host-tissue cell interactive properties. However, the use of cytotoxic crosslinking reagents, and low mechanical strength of these hydrogels and their short-term structural stability are the major issues for their applications in musculoskeletal tissue engineering.

Traditionally, the leaves of S. frutescens are mainly used as a tea, but these traditional dosage forms have several disadvantages, including that they are not particularly convenient to prepare and store, encourage dosage inaccuracy and are highly susceptible to microbial contamination. To solve these problems, dried aqueous extract forms, e.g. freeze dried aqueous extract (FDAE) of S. frutescens were prepared, but they, in turn, may still suffer from instability

Abstract:

Doutoramento em Química<br>During the last years, the use of high hydrostatic pressure (HHP) as a non-thermal technology for preservation or aging of wine has increased substantially in the academic community. However, HHP treated wine has been only analysed after the pressure treatment, with no knowledge available on the effects of HHP during subsequent storage. The results presented in this thesis showed that HHP treatments influence the chemical and sensorial properties of wine during storage. The application of high hydrostatic pressure treatments in winemaking for wine preservation, as a

Abstract:

Com o objetivo de avaliar o processo de secagem da glândula mamária de vacas da raça Holandesa foram examinadas 44 mamas na fase final da lactação, durante a evolução do processo de secagem (dia da última ordenha; 1º, 3º, 5º, 7º, 10º, 15º, 30º e 45º dia do período seco), assim como no retorno à lactação. Antes da colheita das amostras, a glândula mamária era submetida a minucioso exame clínico por inspeção e palpação, sendo complementado pela avaliação do aspecto da secreção láctea. Após os primeiros jatos da secreção terem sido desprezados, procedia-se a sua colheita asséptica, para ser utili

Abstract:

L'objectif de cette thèse a été de mesurer comment les modifications des régimes hydrologiques, plus particulièrement les exondations, régissent 1) certains aspects du fonctionnement des zones humides, 2) l'organisation et la dynamique à court terme des communautés végétales aquatiques et 3) la survie et la réponse plastique des végétaux aquatiques. Cette thèse aborde les questions à des échelles spatio-temporelles différentes. Premièrement, à l'échelle de la décennie, j'ai mesuré la conséquence de la baisse de la hauteur d'eau des zones humides péri-fluviales sur leur physico-chimie. Deuxième
