Cellulose hydrolysis by Trichoderma reesei cellulases: Studies on adsorption, sugar production and synergism of cellobiohydrolase I, II and endoglucanase II

Three major cellulases, cellobiohydrolase I and II (CBH I and II) and endoglucanase II (EG II) of Trichoderma reesei have been purified by ion-exchange chromatography in an FPLC system. Microcrystalline cellulose (Avicel) was hydrolysed by the single enzymes and by equimolar mixtures of CBH I-CBH II and CBH I-EG II. Enzyme adsorption was followed indirectly by selectively quantifying the enzymes i

Beta cell function in autoimmune diabetes in young adults

Popular Abstract in Swedish Sverige har den näst högsta frekvensen av nyinsjuknade typ 1 diabetespatienter i världen, ungefär 20-25 av 100.000 personer utvecklar sjukdomen varje år, både bland personer i åldern 0-15 år och bland de som är 15-34 år. Insulin är den nyckel som öppnar upp cellerna så att sockermolekylen kan komma in i cellen och fungera som bränsle. Insulin bildas i de Langerhanska öaThis thesis presents the results from a study of the first four years of diabetes in 879 patients aged 15-34 years at diagnosis. The aims of this study were to compare clinical classification with the presence of autoantibodies, to study the natural course of beta cell function during the first years of disease and to define predictive factors for the remaining beta cell function after diagnosis.

Laparoscopy Diagnostic applications in suspected appendicitis and access-related complications

Laparoscopic surgery was introduced to minimize patient trauma. However, fatal technique specific complications, due to major vascular or visceral injury, were at times seen related to blind abdominal access using the Veress technique. A modified open access technique was developed and evaluated in 100 patients and found to be fast and easy to learn with few associated complications. This open te

Waterborne Alkyd-Acrylic Hybrids with High Solids Content -Preparation and Properties-

The work presented in this thesis concerns the preparation, characterization and film formation of a waterborne alkyd-acrylic hybrid system with high solids content of about 80 %. The alkyd-acrylic hybrids were prepared by slowly adding a linseed oil alkyd to an acrylic latex dispersion under stirring. In this work two acrylic dispersions with different glass transition temperatures were used in t

Vilket svenskämne? Grundskolans svenskämnen i ett lärarutbildningsperspektiv

Popular Abstract in Swedish I "Vilket svenskämne? Grundskolans svenskämnen i ett lärarutbildningsperspektiv" beskrivs hur en grupp blivande 1 till 7-lärare förhåller sig till olika svenskämneskonceptioner genom lärarutbildningen. Avhandlingen har det dubbla syftet att analysera och tolka de studerandes svenskämneskonstruktioner och att institutionsanalytiskt granska utbildningen. Det empiriska matWhich Swedish? Swedish as a school subject, from the perspective of teacher training describes how a group of future teachers of years 1 to 7 of the compulsory school relates to various concepts of the subject Swedish through three courses delivered at the School of Education. The study has the aim of analyzing the students' construction of the subject of Swedish as taught in school, and to analys

Influence of solid solutions on the properties of some apatite-type calcium salts relevant to the production of phosphate and silicate cements

The effects of non-stoichiometry and isomorphic substitutions on the properties of some apatite-type compounds were investigated. These investigations were performed both in the fields of Portland cement chemistry and apatitic calcium phosphate-based biocements. Apatite compounds were synthesized by solid state methods and by hydrolysis of the reactant α-tricalcium phosphate (α-TCP). The materials
