The thermophilic bacterium Rhodothermus marinus produces several thermostable glycoside hydrolases. The studies presented in this thesis were performed on two enzymes, belonging to glycoside hydrolase families 10 and 12, produced by this microorganism. The family 10 xylanase, Xyn10A, is modular in architecture consisting of five domains or modules. The two isolated N-terminal modules were produced

Agricultural policies have always had a tendency to be controversial. In many cases they generate major transfers of welfare between different groups of people, and hence are favoured by some and criticised by others. They also frequently cause trouble at the international level as domestic programmes interfere with trade flows and affect the wellbeing of people in other parts of the world. In add

Popular Abstract in Swedish Denna avhandling behandlar katalysatorer för organiskt kemiska reaktioner och är speciellt inriktad på de separationstekniska problem som användandet av sådana katalysatorer medför. Kemiska reaktioner sker endast om de är energimässigt gynnsamma. Många möjliga reaktioner sker emellertid endast mycket långsamt. Orsaken kan vara att vägen från reaktant till produkt går viIncorporation of the triamine, bis(2-diethylaminoethyl) amine as a side chain substituent on triphenylphosphine, (2S,4S)-4-diphenylphosphino-2-diphenylphosphino-methylpyrrolidine (PPM) or (R,R)-3,4-bis(diphenylphosphin)pyrrolidine (Pyrphos) gives the three new amphiphilic ligands N3P, N3PPM and N3-Pyrphos respectively. Because of the triamine functionality the distribution of the ligands and their

In connection to an environmental investigation of a former industrial site, the cretaceous sandy limestone bedrock in the surrounding area were mapped with resistivity and time domain induced polarization (DCIP). The aim of the DCIP survey was to delineate geological units and possible preferential pathways of DNAPL contaminated groundwater. Although IP anomalies corresponding to fractured crysta

Popular Abstract in Swedish Inledning För att kunna sätta in resurser där de behövs bäst, finns det en önskan att kunna förutsäga vilka graviditeter som kommer att bli komplicerade. Vid preeklampsi (havandeskapsförgiftning), tillväxthämning hos fostret samt blodproppssjukdom finns det idag inget säkert sätt att tidigt i graviditeten veta vilka som kommer att drabbas. Denna oförmåga att kunna föruThe aim of this thesis was to improve background knowledge for making a reliable medical evaluation at the first visit of a woman in her 13th gestational week, to the antenatal clinic. We have focused on the prediction and the risk estimation of preeclampsia, intra-uterine growth restriction (IUGR), and thrombosis. The thesis was based on five studies, in which we have evaluated biochemical analy
