Abstract:
The composition of gellan gum elaborated by wild type <I>Sphingomonas paucimobilis </I>was studied. Gas chromatographic methods of analysis were compared. Analysis of neutral sugars was carried out by Saemen hydrolysis and Stones method. Stones method was preferred due to its simplicity and the production of comparable results to those obtained following Saemen hydrolysis. The neutral sugars of gellan gum were analysed by GC/MS following preparation of per-methylated alditol acetates (PMAAs). Two methods were used for making alditol acetates, the Hakamori and sodium hydroxide (NaOH) methods. A

Abstract:
This research shows, for the first time, the freeze dried low acyl (LA) gellan gum, high acyl (HA) and HA:LA mixture gel structures and their properties upon rehydration. The water interaction with the gel structure is affected by the presence of acyl groups along the HA gellan gum polymer chain. The rehydration rate was shown to be lower for HA gellan gum and was not dependent on the polymer concentration. In the second instance, the effect of the gel pH on the freeze- and oven-dried structure is studied as well as the water re-absorption extent and rate. In this part, two drying methods, fre

Abstract:
Gelation of polysaccharides under shear conditions results in the formation of a weak gel which is able to resist elastic mechanical deformation at small strains but will flow if subjected to higher strains. The resulting material, described in the literature as a fluid gel or a sheared gel, consists of gelled microparticles which can be formulated to collectively act in bulk, as pourable viscoelastic fluids whilst retaining true gel characteristics at the micro/nano level. The tuneable behaviour of these fluid gel systems makes them potentially useful in pharmaceutical applications. Fluid gel

A novel approach that may impact on satiety, whilst meeting the demands of consumers, is the use of hydrocolloids that respond to the environment (acidic) conditions inside the human stomach by self-structuring. This thesis seeks to investigate the in vitro acid-induced gelation (“structuring”) of the mixed biopolymer systems; low-acyl and high-acyl gellan gum, and low-acyl gellan fluid gels. To explore this concept, a variety of acid structures were obtained, which were characterised by texture analysis, rheology and dynamic scanning calorimetry.

Abstract:
Syftet med undersökningen är att samla in data över barns räknande och räkning av antal samt över hur pedagoger uppmuntrar barn till räkning för att pröva om resultaten svarar mot Gelman och Gallistels fem principer. De metoder som användes var observation och kvalitativa intervjuer, vi observerade Gelman och Gallistels fem principer i samlingar, fria aktiviteter och i rutinsituationer. Vi intervjuade förskollärare om deras syn på matematik och deras arbetssätt i verksamheten. Våra resultat visar att de tre första principerna kommer till uttryck i barnens beteende i alla pedagogiska aktivitete

Puig abstracted the fusion data of a finite group to the notion of fusion system, an object that reflects local data in more abstract algebraic settings, such as the block theory of finite groups. Martino and Priddy conjectured that the algebraic data of a fusion system of a finite group should have a topological interpretation, which result was p

Abstract:
We give an overview of the basic properties of Banach Algebras. After that we specialize to the case of commutative Banach Algebras and study the Gelfand Map. We study the main characteristic of that map, and work on some applications.

A travers un nombre fini de thèmes obsessionnels, le poète élaborera un univers original caractérisé par l'intertextualité, la création linguistique et poétique, le rythme du vers, les hétéronymes, l'engagement, la perte et l'exil, la douleur ou la joie de l'instant, témoignant d'une esthé

Abstract:
Conventional, forced, non-resonant oscillatory rheometers can possess limitations in the measurement of some gels, where they display a pronounced mechanical weakness, are highly shear sensitive and exhibit marked time dependence. Instead, shear wave propagation techniques are proposed as one alternative. One instrument that employs shear wave propagation techniques in the determination of the dynamic shear moduli, G' and G", is the Pulse Resonance Rheometer. The Pulse Resonance Rheometer uses two modes of operation, measurements of the velocity of pulse propagation and measurements of the res

Abstract:
The atomization of a gelled boron slurry fuel using two commercially available airblast atomizers was studied at atmospheric pressure in non-reacting flow. The atomization of water was also characterized for comparison. Each atomizer was operated at two different liquid mass flow rates and several air/ fuel ratios. Drop size distribution was measured using a Malvern 2600 HSD Laser Diffraction Particle Sizer, Drop sizes acceptable for use in ramjet combustors could be obtained for the gelled slurry fuel from both atomizers. However, this required air/fuel ratios too high for practical app
