The objective of the present thesis was to understand how the quality and performance of dried cassava products could be developed by drying and other processing steps. This goal was achieved in several stages. First, a survey of the composition of six cassava varieties from Bolivia, was performed, which resulted in the report of chemical and mineral compositions of the tubers. The mineral composi
This thesis concerns economic aspects of ageing and investigates incentives and outcomes related to this process. The thesis is a collection of five essays. An introductory chapter provides an overall economic perspective of ageing. Essay 1 (ch 2) examines mortality risks via duration analysis of widowed individuals in Scania, Sweden during the 19th century. The findings are qualitatively in line
Popular Abstract in Swedish En av dagens största utmaningar är de stadigt ökande utsläppen av förorenande avgaser och drivhusgaser. Den största delen av dessa föroreningar kommer från förbränningsanläggningar och fordon. För att kunna minska utsläppen måste man förstå förbränningsprocesserna, och hur man kan kontrollera förbränningen. Utmaningen är att förbränningprocesser är mycket komplexa. Det To deal with complex physical and chemical processes in reactive systems, such as combustion processes, it is necessary to find methods that simplify modelling in such a way that it becomes both more comprehensible and practically useful. In the work reported here a method for automatically reducing chemical reaction mechanisms has been developed for use in computer simulations of various combusti
Popular Abstract in Swedish Datorgrafik handlar om att övertyga betraktaren. En huvuduppgift är att generera verklighetstrogna bilder utifrån tredimensionella modeller. Med hjälp av datorer simuleras hur dessa modeller interagerar med ljus. Betraktaren skall helst inte reflektera över om bilden han ser är ett fotografi eller en helt och hållet genererad bild. I denna avhandling presenteras algoritModern graphics hardware pipelines create photorealistic images with high geometric complexity in real time. The quality is constantly improving and advanced techniques from feature film visual effects, such as high dynamic range images and support for higher-order surface primitives, have recently been adopted. Visual effect techniques have large computational costs and significant memory bandwid
Six-membered cyclic carbonates are potential monomers for phosgene and/or isocyanate free polycarbonates and polyurethanes via ring-opening polymerization. A two-step process for their synthesis comprising lipase-catalyzed transesterificationofa polyol, trimethylolpropane(TMP) with dimethylcarbonate(DMC)in a solvent-free system followed by thermal cyclization was optimized to improve process effic
A magnetic particle-based immuno-supported liquid membrane assay (m-ISLMA) based on chemiluminescence detection of a horseradish peroxidase-labeled hapten tracer that allows sample cleanup, analyte enrichment, and detection in a single analysis unit has been developed. Antibodies were immobilized on magnetic beads, and their position in the acceptor was controlled by two alternating opposing elect
The mechanism of action for the anti-arthritic effect of methotrexate (MTX) was investigated in rats with antigen-induced arthritis (AIA). Arthritis intensity was quantified as area under the curve (AUC) for the joint swelling. The response to MTX was in several respects similar to what is seen in the clinic. The drug reduced the AUC in a dose-dependent manner after oral weekly (2-4 mg/kg/week) or
A shear-enhanced, cross-flow ultrafiltration module was used to separate cells and proteins from the fermentation broth. Three (fermented) media were studied: rich medium, rich medium with hydrolytic enzymes added after fermentation, and wheat flour hydrolysate. To find a membrane with as high a flux as possible, but still capable of separating cells and proteins from the lactic acid containing br
Context. The Gaia-ESO Public Spectroscopic Survey will observe a large sample of clusters and cluster stars, covering a wide age-distance-metallicity-position-density parameter space. Aims. We aim to determine C, N, and O abundances in stars of Galactic open clusters of the Gaia-ESO survey and to compare the observed abundances with those predicted by current stellar and Galactic evolution models.
Background: Integration of second-generation (2G) bioethanol production with existing first-generation (1G) production may facilitate commercial production of ethanol from cellulosic material. Since 2G hydrolysates have a low sugar concentration and 1G streams often have to be diluted prior to fermentation, mixing of streams is beneficial. Improved ethanol concentrations in the 2G production proce
Små regulatoriska molekyler i vårt blod Sedan det mänskliga genomet kartlades i början av 2000-talet har stora upptäckter gjorts och teknikutvecklingen har gått fort. Dagens sekvenseringsmaskiner är kraftfulla och kan sekvensera hela det mänskliga genomet på bara två dagar. I mitt masterarbete har jag undersökt små korta RNA-molekyler i mänskligt blod. Denna typ av molekyler är mycket lovande somAbstract In recent years focused research aimed at finding new specific and sensitive biomarkers for detection, classification and, monitoring of human cancers has been ongoing. MicroRNAs (miRNAs) are small, 19-24 nucleotides, noncoding RNAs that are stably expressed in body fluids such as blood. These circulating RNAs have shown great promise as biomarkers, because the unique expression patterns

Development of environmentally friendly and cost-efficient energy sources has been a challenge for modern society since long ago. Sunlight is an infinite and costless source of energy on Earth, so it would be an enormous advantage to efficiently harvest and transform it into electrical energy used in our everyday life. In nature the process, which converts light energy into chemical energy, is cal
Large and complete glaciotectonic sequences formed by marine-terminating glaciers are rarely observed on land, hampering our understanding of the behaviour of such glaciers and the processes operating at their margins. During the Late Weichselian in western Iceland, an actively retreating marine-terminating glacier resulted in the large-scale deformation of a sequence of glaciomarine sediments. Du
Inference of antibody gene repertoires using transcriptome data has emerged as an alternative approach to the complex process of sequencing of adaptive immune receptor germline gene loci. The diversity introduced during rearrangement of immunoglobulin heavy chain variable (IGHV), diversity, and joining genes has however been identified as potentially affecting inference specificity. In this study,
Knowledge of dynamics in protein is very important in the description of protein function and molecular recognition. The thesis investigates protein dynamics on time-scales from milli- to sub-nanosecond, with focus on the latter, using NMR spin relaxation experiments on two proteins, the 138-residue carbohydrate recognition domain of galectin-3 (Gal3C) and the 56-residue B1 domain of bacterial pro
The thesis work concerns development and application of four versatile nonlinear optical techniques, based on exploiting ultrashort laser pulses, for diagnostic purposes in gases and flames. The four techniques, all laser-based, are two-photon laser-induced fluorescence (TPLIF), hybrid femtosecond/nanosecond (fs/ns) rotational coherent anti-Stokes Raman scattering (fs/ns RCARS), fs-laser-induced g
Bergskedjor är uppbyggda av olika slags berggrund som skjutits samman i de zoner på Jorden där tektoniska plattor möts (konvergerar). Sådana processer sker i dag exempelvis i Himalaya, Alperna eller Anderna, men det finns också gamla, nu inaktiva, bergskedjor som de Skandinaviska Kaledoniderna (ca 400 miljoner år gammal) eller den Svekonorvegiska bergskedjan (ca 1000 miljoner år gammal, i sydvästrThe 1.1-0.9 Ga Sveconorwegian orogen is one of several Grenvillian-aged orogenic belts that mark the amalgamation of supercontinent Rodinia. The highest-pressure rocks in the Sveconorwegian orogen are eclogites in the Eastern Segment (SW Sweden). The eclogites occur in a nappe in the high-grade metamorphic level of the Eastern Segment that represents a window into the deepest part of this Precambr
Dyskinesia seen in the off-state, referred as graft-induced dyskinesia (GID), has emerged as a serious complication induced by dopamine (DA) cell transplantation in parkinsonian patients. Although the mechanism underlying the appearance of GID is unknown, in a recent clinical study the partial 5-HT(1A) agonist buspirone was found to markedly reduce GID in three grafted patients, who showed signifi
