Human glandular kallikrein 2 (hK2) is a serine protease, which is predominantly expressed by the prostate gland and found in seminal plasma at mean levels of 6 mg/ml. It has 79% amino acid sequence identity with prostate-specific antigen (PSA or hK3). The aim of this work was to produce hK2 by recombinant expression technologies in order to study its biochemical and biological properties and its
Ukraine has significant potential for bioenergy. Biomass can supply 1 EJ/year or 18% in the country’s energy balance. The major part of this is formed by agricultural residues and energy crops. Annually nearly 175 PJ can be derived from straw, which is currently not used elsewhere. At present the biofuels sector in Ukraine is not established although a number of initiatives have emerged. Biomass s
Heterogeneity in patient populations is an important issue in health economic evaluations, as the cost-effectiveness of an intervention can vary between patient subgroups, and an intervention which is not cost-effective in the overall population may be cost-effective in particular subgroups. Identifying such subgroups is of interest in the allocation of healthcare resources. Our aim was to develop
Popular Abstract in Swedish Vi vill bevara naturbetesmarker och deras skönhet, vilken bland annat utgörs av de olika växtarter som förekommer där. Men idag finns det tyvärr inte många betesmarker kvar. Naturbetesmarkerna har under de senaste två sekelerna försvunnit på grund av ökad eller minskad markanvändning, där betesmarker blivit omvandlade till antingen åkermark eller skog. Bristen på betesmLarge areas of grazed, species rich semi-natural grassland were lost in Europe during the last two centuries and as a consequence led to decreases in grassland specialist species. Therefore, today the “restoration” of grassland on previously arable fields is recommended for the protection of grassland specialists. Even “substitute habitats” for lost grasslands are discussed as temporary alternativ
Magnetomotive ultrasound imaging is an emerging technique where superparamagnetic iron oxide nanoparticles can be used as an ultrasound contrast agent. A time-varying external magnetic field acts to move the particles lodged in tissue, and ultrasound is used to detect the resulting tissue movement. In phantom studies we have observed opposite phase motion next to regions containing nanoparticles.
Abstract in UndeterminedThe demands for energy efficent heating solutions for the manufacturing industry can be met by a new induction heating platform, presented in this article. A new concept and technology to design and manufacture induction heating units is explained, evaluated and tested with successful results. The so called Greenheat technology relies on inductors built on Litz wiring mould
Popular Abstract in Swedish Denna avhandling handlar om utveckling och tillämpning av metoder för jonstråleanalys av lätta ämnen (lättare än ungefär aluminium), framförallt vid en nukleär mikrosond. Vid en nukleär mikrosond accelereras tunga partiklar, t.ex. protoner, av en partikelaccelerator och fokuseras av ett speciellt magnetiskt linssystem ned till en storlek av ungefär 1 mikrometer. Denna sThis thesis treats the development of Ion Beam Analysis (IBA) methods, principally for the analysis of light elements at a nuclear microprobe (NMP). The light elements are in this context defined as those with an atomic number Z of less than approximately 13 (aluminium). The work reported is to a large extent based upon multiparameter methods. Several signals are acquired simultaneously, and the d
Popular Abstract in Swedish Kan man förutse risk för suicid med psykiatriska skattningsskalor? Omkring 20.000 suicidförsök registreras varje år i Sverige. Denna siffra borde dock sannolikt vara högre, eftersom bara de individer som kommer i kontakt med sjukvården räknas. Antalet fullbordade suicid har länge ansetts vara cirka 10 % av dessa, d.v.s. cirka 2000 personer per år. Sedan några år har doA decline of suicide rate can be accomplished by different psychiatric interventions. Early identification of individuals at risk for future suicide is especially important. Results from rating scales could add detailed information, which in turn might strengthen a psychiatric suicid risk assessment. This thesis deals with emergency evaluations and psychiatric inpatient evaluations after a suicide
This paper provides a complete circuit for a low-loss non-conventional power MOSFET or IGBT driver. The driver, which provides galvanically separated input and output signals, is fed from a unipolar DC voltage but provides a bipolar gate-source voltage. The driver applies two, already known, techniques and together they form a resonant galvanically separated power MOSFET/IGBT gate driver. The firs
Popular Abstract in Swedish Vår kropp består av en till synes oändlig mängd individuella celler. För att alla dessa celler skall kunna fungera som en helhet måste de meddela sig med varandra. För att en cell i tån ska kunna känna av vad som händer i knät så har den bland annat receptorer på sin yta. Receptorer är proteiner som sitter förankrade i cellens yttre skal, i cellmembranet. Receptorns enaInformation about extracellular proteolytic activity is transduced to the cell by a transmembrane G-protein coupled receptor subfamily. These receptors are activated by proteolytic cleavage in the extracellular amino-terminal domain and are thus termed proteinase-activated receptors (PARs). The second member of this subfamily, PAR-2, is activated by trypsin-like proteinases, however the physiologi
Highly compacted bentonite has been proposed as the buffer material in the Swedish concept for the disposal of nuclear waste. To increase the knowledge of the hydro-mechanical behaviour of unsaturated swelling bentonite a series of laboratory experiments was carried out. The main purpose was to conceptually model the hydro-mechanical behaviour of the bentonite. The influence of testing techniques
