Conclusions. Thorough otomicroscopical examination of the tympanic membrane in acute otitis media (AOM) might distinguish AOM episodes caused by different bacteria. It thus might be a way to select appropriate treatment for each patient without raising the number of dangerous complications. Objectives. The aim of this study was to see if it might be possible to predict the causative bacterium by j

alpha 1-Antitrypsin (AAT), a major endogenous inhibitor of serine proteases, plays an important role in minimizing proteolytic injury to host tissue at sites of infection and inflammation. There is now increasing evidence that AAT undergoes post-translational modifications to yield by-products With novel biological activity. One Such molecule, the C-terminal fragment of AAT, corresponding to resid

The location of lipoprotein lipase activity in rat adipose tissue was studied using intact epididymal fat pads, isolated adipocytes, and lipoprotein lipase activity secreted from adipocytes as enzyme sources. The enzyme activities of these preparations were characterized by gel filtration. The method used for isolation of adipocytes had been modified to minimize activation of lipoprotein lipase du

Background: Retinoids are vital for embryonic development; both excesses and deficiencies of vitamin A are known to give similar patterns of birth defects. Concentrations of retinol in newborns and in pregnant women have been investigated, but concentrations of the biologically active metabolite all-trans retinoic acid and its isomer 13-cis retinoic acid have not. Objective: We measured serum conc

Three new diarylheptanoids, (4Z,6E)-5-hydroxy-1-(4-hydroxy-3-methoxyphenyl)-7-(4-hydroxyphenyl)hepta-4,6-dien-3-one, letestuianin A (1), (4Z,6E)-5-hydroxy-1,7-bis(4-hydroxy-3-methoxyphenyl)hepta-4,6-dien-3-one, letestuianin B (2), and 1,7-bis(4-hydroxyphenyl)heptan-3,5-dione, letestuianin C (3), as well as the known (4Z,6E)-5-hydroxy-1,7-bis(4-hydroxyphenyl)hepta-4,6-dien-3-one (5) were isolated f

Rapporten beskriver en studie som syftat till att undersöka och beskriva tre typer av Probiks fuktindikatorer från Alfasensor AB. De olika typerna är Probiks CO, BI och HU. Studien är delvis utförd på laboratorium och delvis i fält på en byggarbetsplats. I rapporten har även erfarenheter från mätningar i befintliga byggnader sammanställts. I studien har en rad experimentella försök av indikatorern

Background: Life expectancy in Sweden is currently one of the longest in the world. The population of Halland has the longest life expectancy in Sweden. Aim: Life expectancy in the province of Halland and Sweden as a whole during 1911-50 was studied and the findings are discussed in the light of local historical data. Method: A trend analysis of risk ratio of death and life expectancy for Halland

Popular Abstract in Swedish Under senare år har datorn kommit att bli ett vanligt inslag i förskolans dagliga verksamhet. Visioner och planer har formulerats, inte minst politiskt. Det har sedan varit upp till pedagogerna att organisera och genomföra datoranvändandet i den lokala förskolevardagen. Avhandlingens övergripande syfte är att studera datoranvändandets praktik i förskolan. Avsikten är däThe purpose of this thesis is to study the computer using practice within pre-school activity, or more specifically, to study aspects of meaning-making as afforded when the computer is in use in pre-school. In the study a socio-cultural perspective is used as the point of departure combined with an Ecological approach to visual perception and Positioning theory. Data was collected in three pre-sch

Source-sorted municipal organic waste from different dwelling types in five Danish cities was sampled during one year. The samples were from permanent, full-scale systems or temporary, experimental systems for collection of source-sorted municipal organic waste. Pre-treatment of the organic waste prior to biological treatment was used in all cities to remove foreign objects and provide size reduct

Efficient inventory control depends on correct values of inventory cost parameters, such as holding costs, shortage/stockout costs and ordering/setup costs. However, there exists surprisingly little research concerning the size of these parameters or how they should be determined. This thesis is devoted to increasing our knowledge of these matters. The research is presented in the form of five sc

This study presents a simple and rapid solvent exchange procedure using a hollow fiber. Antioxidants (Irganox 1010, Irganox 1076 and Irgafos 168) and solvents such as tetrahydrofuran (THF), carbon tetrachloride and toluene were selected as model compounds and sample solvents, respectively. After injection of the sample solution into the hollow fiber and solvent evaporation, the precipitated analyt
