Hydrophobic Fusion Tags: Implications For Bioseparation and Cellular Expression

The studies in this thesis have shown that the partitioning of endoglucanase I (EGI, Cel7B) from T. reesei could be significantly improved by relatively minor genetic engineering. By adding short peptides composed of tryptophan and proline residues to EGI, extreme partitioning could be obtained. The site of the tag fusion was shown to be crucial for the efficiency of the tag. Methods suitable for

The development of psychoanalytic explanations of PTSD and assoicated disorders with a special focus on the somatic sequelae to torture

PTSD or Post Traumatic Stress Disorder (or, earlier, Syndrome) covers a great variety of symptoms which develop in a variety of contexts – accidents, natural disasters, terrorist attacks, wars and other events where people come face to face with violence and death. PTSD was included in the third edition of the Diagnostic and Statistical Manual of Mental Disorders, DSM-III, during the early 1980s.

LES of swirling flows in gas turbine combustion chambers

The flow and mixing in a swirl-stabilized gas-turbine burner is studied by Large Eddy Simulations (LES). Each swirler has a different mass flux and swirl angle. The interaction between neighbouring jets is studied, co-rotating and counter rotating jets are considered. Another issue of importance is related to the jet inlet conditions (e.g. axial distribution and levels of turbulence). In addition

Klassikernas roll i post-sovjetisk televison

I Ryssland spelar de litterära klassikerna en roll som på ett avgörande sätt skiljer sig från svenska förhållanden. På grund av den utbredda analfabetismen vid bolsjevikernas makttillträde har böcker och läsande blivit starkt förknippade med det sovjetiska moderniseringsprojektet. De nya makthavarna såg som sin uppgift att sprida det som i väst har uppfattats som ett borgerligt bildningsideal till

Cyclic nucleotide signalling systems in vascular smooth muscle cells and immune system cells with special reference to phosphodiesterases PDE3 and PDE4

Popular Abstract in Swedish Bakgrund: Signalsystem Alla flercelliga organismer är beroende av informationsöverföring mellan celler. Det behövs signaler från andra celler för att reglera tillväxt, ämnesomsättning m. fl. funktioner i olika vävnader. Oftast överförs signalerna via kemiska ämnen som antingen verkar i hela kroppen (hormoner) eller lokalt. När dessa ämnen når målcellen, binds de till eThe cyclic nucleotide signalling systems are important in vascular smooth muscle and in the immune system, and are of interest from a pharmacological point of view. Drugs which interfere with the cyclic nucleotide levels have profound effects on heart, blood vessels and airways and have actual or potential use in several important diseases, such as heart failure, hypertension, arteriosclerosis, as

Publish Late, Publish Rarely! : Network Density and Group Performance in Scientific Communication

Research programs regularly compete to achieve the same goal, such as the discovery of the structure of DNA or the construction of a TEA laser. The more the competing programs share information, the faster the goal is likely to be reached, to society’s benefit. But the “priority rule”-the scientific norm according to which the first program to reach the goal in question must receive all the credit

A new look at the error-correcting capabilities of convolutional codes

This paper describes the error-correcting capability of a convolutional code when transmitting close to capacity. We show that it is the combination of average burst length and first event error probability that allows us to better describe the error-correcting capability of a code
