Osmoderma eremita is a threatened scarab beetle living in the hollows of old deciduous trees and is regarded as an umbrella species of the beetle fauna associated with this habitat. Several methods like pitfall trapping and wood mould sampling have been used to monitor the occurrence of O. eremita, but these methods cannot be applied for trees with certain characteristics. Recently, (R)-(+)--decal
Accumulation of boron in tumor tissue is an indispensable requirement for boron neutron capture therapy and it is important that the uptake is as high as possible. In this work we have studied the influence of electropermeabilization in vivo on the uptake of boron in normal and RG 2 glioma bearing Fischer 344 rats. Two different boron compounds, a sulfhydryl boron hydride (BSH) and a boronated por
Motivation: The above-ground tissues of higher plants are generated from a small region of cells situated at the plant apex called the shoot apical meristem. An important genetic control circuit modulating the size of the Arabidopsis thaliana meristem is a feed-back network between the CLAVATA3 and WUSCHEL genes. Although the expression patterns for these genes do not overlap, WUSCHEL activity is
Queer/ed children and young people inhabit a space that seems nicely delineated by shamed biographies, fearful prospects and ignorance. In mainstream accounts, queer/ed children and young people are often un/represented through invisibility or drama, between exoticism and pity. ‘Children’ and notions of ‘the best interest of the child’ are used to dramatize and limit societal negotiations of sexua
High accuracy and low computational costs are essential properties for efficient finite element codes. Improvements of the finite element method in order to satisfy these qualities have been the subject for extensive research activities ever since its introduction. In this thesis, a class of improved low-order finite elements is proposed which possesses high accuracy in bending even for coarse
Hassles and uplifts, a concept used in measuring daily stress events, was applied to working mothers' everyday life. The aim was to explore the stability in working mothers' experiences in patterns of daily occupations, operationalized as hassles and uplifts, between the year 2000 (baseline) and the year 2005 (follow-up). Further, the intention was to reveal possible differences in the number, ori
Energies with high-order non-submodular interactions have been shown to be very useful in vision due to their high modeling power. Optimization of such energies, however, is generally NP-hard. A naive approach that works for small problem instances is exhaustive search, that is, enumera- tion of all possible labelings of the underlying graph. We propose a general minimization approach for large gr
Measurement of prostate-specific antigen (PSA) in blood is an important tool in detection for prostate cancer. PSA occurs in several molecular forms in blood: mainly as a free form with a molecular mass of 28 kDa; and as PSA complexed to alpha-1-antichymotrypsin, complexed PSA, with a molecular mass of 90 kDa. Total PSA comprises the sum of free PSA and complexed PSA. The percentage of free-to-tot
Trichoderma cellulases appear in several isoforms which makes their purification and analysis difficult. We used fast protein liquid chromatography (FPLC) to purify three major cellulases and to quantitate these enzymes in reconstituted mixtures during cellulose hydrolysis studies (in lack of specific substrates and because of the synergism between the enzymes such analysis is very difficult, if a
Popular Abstract in Swedish Summary in swedish Perinatal dödlighet bland invandrare från Afrikas Horn. Vikten av erfarenhet, rationellt tänkande och traditioner vid riskbedömning av gravida invandrarkvinnor. Avhandlingen visar att barn till kvinnor i invandrargrupper från Afrika söder om Sahara (majoriteten från Somalia och Etiopien), har högre perinatal dödlighet jämfört med barn till svenska kThis thesis is an exploration of the possible effects of maternal country of origin on the risk of perinatal mortality (PNM). Increased risk of PNM was found among infants of foreign-born women delivering in a Swedish hospital between 1990-1995. After adjustment for risk factors, however, the finding only held true for a subgroup of women from Ethiopia and Somalia (ES). In searching for the mecha
Popular Abstract in Swedish Trastsångarnas MHC gener i klarspråk Inuti kroppen ser vi väldigt lika ut allihop; men om mina njurar skulle sluta att fungera är det inte alls säkert att just du kan donera en njure till mig. Detta beror på att våra transplantations-gener eller s.k. MHC- (Major Histocompatibility Complex) gener är olika, och vid en transplantation måste många av donatorns och mottagarIn vertebrates the Major Histocompatibility Complex (MHC) plays a central role in the specific immune defence against various pathogens. Compared with other coding genes the MHC genes exhibit an extremely high level of polymorphism that is maintained by balancing selection. The importance in the immune defence and the polymorphism make these genes interesting to study from an ecological and evolut
Engine tests have been performed on a 9.6 liter spark-ignited engine fueled by natural gas and a mixture of 25/75 hydrogen/natural gas by volume. The scope of the work was to test two strategies for low emissions of harmful gases; lean burn operation and stoichiometric operation with EGR and a three-way catalyst. Most gas engines today, used in city buses, utilize the lean burn approach to achieve
OBJECTIVES: The aim of the study was to evaluate glucose levels and insulin secretion early in pregnancy and at a time when gestational diabetes mellitus frequently occurs in order to define reference values for glucose tolerance during pregnancy. The results were also related to maternal factors that might identify subjects at risk of developing gestational diabetes mellitus as well as foetal fac
We study relations among the side-chain asymmetry, structure, and order-disorder transition (ODT) in hairy-rod-type poly(9,9-dihexylfluorene) (PF6) with two identical side chains and atactic poly(9-octyl-9-methyl-fluorene) (PF1-8) with two different side chains per repeat. PF6 and PF1-8 organize into alternating side-chain and backbone layers that transform into an isotropic phase at TODT(PF6) and
Den här avhandlingen presenterar nya metoder och tekniker som utvecklats för att undersöka nanotrådars (NT) och NT-enheters egenskaper, och de resultat som erhållits med dessa.

The growth and characterization of NWs have become a large research field because NWs have been shown to improve the properties of many semiconductor applications such as transistors, solar cells, and light emitting diodes
In the arid irrigated lands, understanding the impact of shallow groundwater fluctuation on soil salinization has become crucial. Thus, investigation of the possible options for maintaining the groundwater depth for improving land productivity is of great importance. In this study, under saline irrigation condition, the effects of shallow groundwater depth on water and salt dynamics in the root-zo
Sprickbildning har observerats på vissa delsträckor av E6 och E45 i Västra Götalands län, Sverige, trots liknande trafikförhållanden och beläggningskonstruktioner. Syftet med denna studie var att undersöka möjliga materialrelaterade faktorer som bidrar till sprickbildning i asfaltbeläggningar. Historiska kvalitetskontrolldata, projektdokumentation och nya fältundersökningar användes för att jämför
Sivakumar et al. (2000a), by employing the correlation dimension method, provided preliminary evidence of the existence of chaos in the monthly rainfall-runoff process at the Göta basin in Sweden. The present study verifies and supports the earlier results and strengthens such evidence. The study analyses the monthly rainfall, runoff and runoff coefficient series using the nonlinear prediction met
Control systems are ubiquitous and often at the core of Cyber-Physical Systems, like cars and aeroplanes. They are implemented as embedded software, that interacts in closed loop with the physical world through sensors and actuators. As a consequence, the software cannot just be tested in isolation. To close the loop in a testing environment and root causing failure generated by different parts of
Starting from the assumption that grammaticalization is rooted in situated language use, the present study tests the connection between functional reanalysis and formal reduction with a synchronic approach. It investigates a case of potential (but not actuated) grammaticalization in Present-Day English, the use of epistemic phrases of the type it could/might be (that), which can serve an adverbial
