Given the rapidly increasing number of women above 50 it is of pivotal importance to consider health issues related to gonadal hormone deficiency. The possibility of alleviating such symptoms by hormone replacement therapy (HRT) should be recognized by all physicians, not merely by gynaecologists. But which women should be given what therapy, and for how long? Due to the increased risk of endometr

Artikeln diskuterar möjligheterna och begränsningarna i äldres tillgänglighet till i IT-samhället under senare delen av 1990-talet. Resultatet från en intervjuundersökning (n=186)visar att äldre IT-användare kan kategoriseras i beroende, akriva och avancerade användare och att detta formas av tillgången, förmågan, förväntningarna, självbilden och dagliga restriktioner (sociala kontexten.

Commercial decabromodiphenyl ether (DecaBDE) is commonly used as a flame retardant in different electrical and textile applications. It is also used in the production of flame-retarded rubber compound. DecaBDE is the major technical polybrominated diphenyl ether (PBDE) in use today and consists mainly of decabromodiphenyl ether(BDE209). PBDEs, including BDE-209, are well-known environmental pollut

Phosphofructokinase (EC 2.7.1.11) and aldolase (EC 4.1.2.13) have been highly purified from Saccharomyces cerevisiae by improved protocols. Partitioning of the enzymes in aqueous polymer two-phase systems was used to detect complex formation. The partition of each enzyme was found to be affected by the presence of the other enzyme. AMP affected the partition of the individual enzymes as well as th

Background: As the incidence of allergy to different compounds increases in society, the need to understand and characterize specific IgE responses becomes F. obvious. Different cell culture systems have been evaluated for their ability to support such IgE secretion. Methods: One system employed human peripheral lymphocytes (PBL) from normal donors stimulated with anti-CD3 activated T cells with o

We have investigated the formation of supported model membranes via the adsorption of phospholipid-surfactant mixtures at the Si water interface by specular neutron reflection. The adsorption of mixed micelles of the nonionic surfactant beta-D-dodecyl maltoside and DOPC or POPC was determined as a function of bulk concentration, and using d(25)-beta-D-dodecyl maltoside, the composition of DOPC and

Fifty years after the foundation of the Combustion Institute and almost 150 years after Michael Faraday's famous lectures on the combustion of a candle, combustion diagnostics have come a long way from visual inspection of a flame to detailed analysis of a combustion process with a multitude of sophisticated techniques, often using lasers. The extended knowledge on combustion phenomena gained by a

Popular Abstract in Swedish Kontrollmekanismerna rörande blodcirkulationen i den mänskliga fetoplacentära enheten är fortfarande inte fullständigt kända, trots genomgripande undersökningar. Det är dock känt att den är viktig för att kunna bibehålla en normal graviditet och för att kunna frambrigna ett friskt nyfött barn. Om kontrollen brister kan utgången försämras i form av tillstånd såsom preeklIn this present study the population of endothelin-like receptors in the human umbilical artery was examined in vitro in different parts of the umbilical cord. Immunohistochemistry revealed ETB receptors in the endothelium and an uneven distribution of ETA receptors in the smooth muscle of the arterial wall, when comparing different parts of the umbilical artery. ET-1 induced vasoconstriction wa

The topic of the thesis is codesign of flexible real-time control systems. Integrating control theory and real-time scheduling theory, it is possible to achieve higher resource utilization and better control performance. The integration requires new tools for analysis, design, and implementation. The problem of scheduling the individual parts of a control algorithm is studied. It is shown how sub

This paper explores the lack of common basic assumptions among different theoretical orientations which constitute the field of sociology of law. It argues that sociology of law lacks theoretical coherence and is, therefore, unable to produce fundamental paradigms. The solution to the paradigmatic shortcomings of sociology of law is, then, sought outside the traditional framework of law and sociol
