Résumé :

This thesis is centred on the use of an isothermal titration microcalori-meter which can measure heat changes of the order of a few microcalories. The calorimeter provides a rapid and convenient method, incorporating a thermodynamic analysis, for estimating enthalpic pairwise interaction parameters, hjj, for solute-j in aqueous solution. Estimates of hjj for three solutes; urea, monoethylurea and hexamethylenetetramine are reported. Comparisons with published estimates of hjj show good agreement, and confirm the importance of the new technology in calorimetry. The critical micellar concentrati

Résumé :

The objective of this work has been to study the binding of metal ions to complex ligands expressing two or more metal binding sites, in terms of the thermodynamics of the binding events, and to use this information to contribute to the understanding of both the metal binding processes and the properties of the metal/ligand complexes. Two ligands have formed the basis of the study, one a naturally occurring enzyme and the other a newly synthesised ligand with two distinct binding sites (to form supramolecular complexes). The principle technique used to determine thermodynamic parameters has be

Résumé :

Nicotine titration was studied in cigarette smokers not interested in cutting down or quitting smoking. Forty smokers were classified as high nicotine dependent (n=20) and low nicotine dependent (n=20) using a validated tolerance questionnaire. Subjects were randomized into baseline (n=10) or nicotine fade conditions (n=10) within their dependency group. Subjects in the baseline conditions smoked their preferred brand of cigarette throughout the experiment. Smokers in the fade conditions switched to a reduced nicotine brand in the latter half of the procedure. Multiple in vivo and in vitro m

Medium chain fatty acids (MCFAs) are essential molecules for a wide range of pharmaceutical, biotechnological, and industrial applications.

Medium chain fatty acids such as capric acid (C10) or lauric acid (C12) have additionally been shown to exhibit antibacterial activity. A number of studies have observed the aggregation behavior of long chain fatty acid using the titration curves by molecular dynamic (MD) simulations. In this study, we performed constant-pH

Although the native environment of the vast majority of proteins is a complex aqueous solution, like the interior of a cell, many analysis methods for assessing chemical and physical properties of biomolecules require the sample to be aerosolized; that is, transferred to the gas-phase. An important example is electrospray-ionization mass spectrometry, which can provide a wide range of information about e.g. biomolecules. That includes structural features, charged sites, and gas-phase equilibrium constants of reactions. To date much of the microscopic detail about the aerosolization process rem

ITC binding studies at 25 °C between tannins and bovine serum albumin (BSA) produced biphasic binding isotherms that were suggested to be indicators of positive cooperative binding.

O estudo da variação da composição atmosférica contribui para a compreensão dos efeitos das emissões antrópicas sobre a troposfera. A análise química da água de chuva assume importância neste contexto, uma vez que a precipitação úmida constitui um excelente meio de remoção de muitos poluentes da atmosfera. O aumento de acidez das chuvas, em várias partes do planeta, tem sido associado, predominantemente, à presença de ácidos fortes como o sulfúrico e nítrico, e ácidos orgânicos como acético e fórmico, originados pela oxidação de compostos de enxofre, nitrogênio e carbono, respectivamente.

Résumé :

Arbetet har mestadels utförts i kokeriet på Domsjö Fabriker i syfte att kartlägga hur processförhållandena hänger samman med koncentrationen sulfatjoner. Detta för att lättare kunna undvika förhållanden i processen som innebär mycket höga värden. Arbetet ingår i examen för högskoleutbildningen: processoperatör vid Umeå Universitet.Vid Domsjö Fabriker har tidigare liknande mätningar gjorts i kokeriet och det har konstaterats att koncentrationen sulfatjoner hänger samman med pH och tid. Syftet är att djupare kartlägga hur processförhållandena hänger samman för att lättare kunna undvika förhållan
