A distillation unit has been designed for a capacity of 73 t/h of condensate and for at least 90% recovery of the contaminating organics. This unit consists of three columns: a primary stripper to remove volatile organics and two upgrading columns to purify the methanol and furfural byproducts. Three different energy-saving alternatives for satisfying the energy requirements have been studied: ut

This thesis is an empirical study of how positioning is achieved in interactional Swedish. Positioning has previously been described in terms of epistemic modality, interpersonal positioning, stanceand speech act adverbials. The aims of the study are, firstly, to identify what linguistic resources are used to achieve positioning in interaction. A second aim is to describe where in the turn-con

La structure de la viande hachée évolue au cours de la cuisson, ce qui a une influence sur les transferts de chaleur et de matière. L'étude a porté sur la friture de steaks hachés de 10 mm d'épaisseur et de 3 à 10 cm de diamètre, provenant de 4 sortes de viande. La cuisson avait lieu entre deux plaques chauffées à 100, 150 ou 175 °C. Elle faisait passer le produit depuis l'état congelé à -20°C jus

Bioelectrocatalytic oxidation of theophylline was studied at gold and graphite electrodes modified with microbial theophylline oxidase (ThOx), a multi-cofactor redox enzyme capable of selective oxidation of theophylline. Gold electrodes were additionally modified with self-assembled monolayers (SAMs) of (-OH)- and (-NH2)-terminated alkanethiols of different chain lengths, to achieve compatibility

The basement rocks of southern Sweden were deeply weathered in Late Triassic through Cretaceous times, and possibly even earlier. Sub-Mesozoic saprolites formed, presumably due to long-term warmth and humidity, in conjunction with decomposition of abundant organic matter and subsequent infiltration of acidic water. The upper parts of the weathering profiles were subjected to intense leaching and k

The SEA coupling and dissipation loss factors are determined in-situ from Complex Modulation Transfer Functions, CMTF:s, based on measured impulse-responses. A quotient of CMTF:s is least-square curve-fitted to a SEA model and the SEA loss factors are determined from the results of the curve-fit. A two subsystem SEA model with time-varying power is considered. In the frequency domain, power-energ

A reliable and inexpensive device for measuring gas with low flow rates is described. The device works based on the principle of liquid displacement and is able to measure flows from 1 to 950 ml(.)h(-1). It also has improved counting logic and data processing capacity to avoid miscounting and provide a friendly interface for data display. (C) 2003 Elsevier B.V. All rights reserved.

Despite the potentially strong effect of wind on bird orientation, our understanding of how wind drift affects migrating birds is still very limited. Using data from satellite-based radio telemetry, we analysed the effect of changing winds on the variation of the track direction of individual birds. We studied adults and juveniles of two raptor species, osprey Pandion haliaetus and honey buzzard P

Maternal intrauterine enterovirus infection during pregnancy increases the risk for the offspring to develop type 1 diabetes mellitus. Type 1 diabetes mellitus and autoimmune thyroiditits (AIT) are closely linked. A common pathogenetic factor is possible. The objective of this study was to investigate a possible association between maternal enterovirus infection during pregnancy and the developmen

It is of central interest in membrane proteomics to establish methods that combine efficient solubilization with enrichment of proteins and intact protein complexes. We have investigated the quantitative and qualitative solubilization efficiency of five commercially available detergents using mitochondria from the yeast Saccharomyces cerevisiae as model system. Combining the zwitterionic detergent

The low Lower Cambrian rocks from the Sierra de Cordoba contain one of the best successions in Europe, which consists of well exposed mixed facies with abundant fossil assemblages showing long stratigraphical ranges throughout the Pedroche Formation. These assemblages include diverse Ovetian archaeocyaths, trilobites, small shelly fossils, calcimicrobes, trace fossils and stromatolites. Trace foss
