We derive a partition function for the Lund fragmentation model and compare it with that of a classical gas. For a fixed rapidity “volume” this partition function corresponds to a multiplicity distribution which is very close to a binomial distribution. We compare our results with the multiplicity distributions obtained from the JETSET Monte Carlo for several scenarios. Firstly, for the fragmentat
Adsorption chromatography in expanded beds is a widely used technology for direct capture of target proteins from fermentation broths. However, in many cases this method cannot be applied as a result of the strong tendency of cells or cell debris to interact with the adsorbent beads. To prevent contamination of the expanded bed with the biomass, STREAMLINE DEAE, anion exchanger designed for expand
Albeit there is a general consensus that urban design in the twentieth century failed in relation to space use, systematic research on this aspect has been very limited or at most inadequate in the developing countries. This study focuses on the above failure of urban design in this century with specific reference to the developing countries through an analysis of Dar es Salaam city centre, Tanzan
Electronic and atomic structure of hexagonal boron nitride (h-BN) on lattice-mismatched transition metal surfaces has been studied systematically by X-ray absorption and photoelectron spectroscopy and diffraction. The strength of interfacial chemical interaction between h-BN and the substrates is rising in the row Pt(111)-Ir(111)-Rh(111)-Ru(0001). This rise directly correlates with a growing corru
Blood coagulation factor V (FV) is a 330 kDa plasma glycoprotein. Activated FV (FVa) is a non-enzymatic cofactor to activated Factor X in the activation of prothrombin that occurs during coagulation. To investigate the molecular mechanisms of the quantitative FV deficiency associated with the FV R2 haplotype (a common genetic variant in several populations), four missense mutations identified in

Popular Abstract in Swedish Arbetare i gummiindustrin utsätts för ett stort antal kemikalier med hög giftighet. Tidigare forskning har visat att kemikalierna innebär en fara för hälsan. Gummiarbetarna har tidigare haft en ökad risk att drabbas av olika sjukdomar, t.ex. cancer, hjärtkärlsjukdomar och luftvägsbesvär, jämfört med allmänbefolkningen. Däremot vet man inte exakt vilka ämnen som är farliWorkers in the rubber industry have an increased risk of several diseases, such as airway disease, cancer and probably cardiovascular disease. The exposure is very complex; carbon disulfide (CS2) and polycyclic aromatic hydrocarbons (PAHs) being two of the contaminants. The general aim of this thesis was to find exposure-response relationships usable for risk assessments in the rubber industry. U
In this study, we present a way of controlling the formation of the two types of zeaxanthin aggregates in hydrated ethanol: J-zeaxanthin (head-to-tail aggregate, characteristic absorption band at 530 nm) and H-zeaxanthin (card-pack aggregate, characteristic absorption band at 400 run). To control whether J- or H-zeaxanthin is formed, three parameters are important: (1) pH, that is, the ability to

The on-line computational demands of model predictive control (MPC) often prevents its application to processes where fast sampling is necessary. This report presents a strategy for reducing the computational delay resulting from the on-line optimization inherent in many MPC formulations. Recent results have shown that feasibility, rather than optimality, is a prerequisite for stabilizing MPC algo
Detergent/polymer aqueous two-phase systems are studied as a fast, mild and efficient general separation method for isolation of labile integral membrane proteins. Mechanisms for phase behaviour and protein partitioning of both membrane-bound and hydrophilic proteins have been examined in a large number of detergent/polymer aqueous two-phase systems. Non-ionic detergents such as the Triton series
A diagnosis-antibiotic prescribing study was performed in 5 counties in Sweden during 1week in November in the y 2000 and 2002, respectively. As part of the study, the characteristics and clinical management of patients who received diagnoses of urinary tract infections (UTIs) ( n = 1564) in primary care, were analysed. 85% of the visits were by women, and 74% of all consultations were diagnosed a
During the course of development the motor repertoire of animals and humans alike go through dramatic changes. New motor patterns arise; movements become coordinated, improve in precision and are at the same time continuously calibrated to the changing body dimensions. The cerebellum is critical for movement coordination and adaptation in adults. Also, interfering with cerebellar development durin
