Improvement of road traffic safety is an important policy issue. Various categories of meas-ures are available to effectuate this. The thesis focuses on two categories: road infrastructure and driv-ing assistance systems. A relevant policy question is if certain driving assistance systems may be de-sirable substitutes for infrastructure measures, in terms of traffic safety effects and other releva
The regulation of phospholipase D was studied in human neuroblastoma cells using phosphatidylethanol as a marker of the enzyme activity. Carbachol induced phospholipase D activity in SH-SY5Y cells. Muscarinic antagonists inhibited the response with potencies suggesting that muscarinic M1 receptors are responsible for the activation. In permeabilized SH-SY5Y cells, both the carbachol- and GTP gamma
Öresund is one of the areas in the world with most ship movements. More than 40,000 ships pass through the sound in the direction north-south or the opposite every year. Other ships/ferries frequently cross the sound in the direction east-west or west-east. The ships carry goods and/or passengers in huge volumes. Since Öresund is a quite narrow sound with a difficult navigation situation, many ris
PIP: The aim of this study was to define epidemiologic and psychosocial characteristics of women with a history of casual travel sex abroad. The participants were 996 women seeking contraceptive advice, of whom 276 admitted that they had experienced casual travel sex. The remaining women served as a comparison group. In structured interviews, questions were asked about educational level, partnersh
Popular Abstract in Swedish Området runt Forsmarks kärnkraftverk i Östhammars kommun, ca 80 km norr om Uppsala, valdes år 2000 ut som en av två möjliga kandidater för byggandet av ett slutförvar för använt kärnbränsle. År 2002 startade SKB (Svensk Kärnbränslehantering AB) en platsundersökning i området, vars syfte bland annat är att samla in tillräckligt mycket kunskap om berget och dess egenskapeThe Forsmark area, in the western part of the Svecofennian orogen, central Sweden, is situated between two major Palaeoproterozoic tectonic domains that show contrasting histories with respect to timing of igneous activity, ductile deformation and metamorphism. At Forsmark, WNW to NW trending, ductile deformation belts anastomose around tectonic lenses with an inferred lower degree of ductile stra
The importance of screening programs in reducing the prevalence of genital chlamydial infections is stressed by the fact that the majority of infected persons are more or less asymptomatic. The use of oral contraceptives may mask infections affecting the upper genital tract. This imposes selective screening and rescreening of women with a history of pelvic inflammatory disease. The recent knowledg
This paper presents theory for stability analysis and design for a class of observer-based feedback control systems. Relaxation of the controllability and observability conditions imposed in the Yakubovich-Kalman-Popov (YKP) lemma can be made for a class of nonlinear systems described by a linear time-invariant system (LTI) with a feedback-connected cone-bounded nonlinear element. It is shown how
AIM: To study the interaction between the human cysteine proteinase inhibitor, cystatin C, and proteinases of periodontitis associated bacteria. METHODS: Gingival crevicular fluid samples were collected from discrete periodontitis sites and their cystatin C content was estimated by enzyme linked immunosorbent assay (ELISA). The interaction between cystatin C and proteolytic enzymes from cultured s
Research has been done on children’s participation in review meetings, a method for reviewing foster and residential care. The method is tested within the national project Children’s Needs in Focus (BBIC) inspired by the British Integrated Children’s System and operated by the National Board of Health and Welfare (Socialstyrelsen) in Sweden. The objective of the evaluation, conducted on behalf of
Background Sick leave due to neck, shoulder and back disorders (NSBD) is higher among health-care workers, especially nursing aides/assistant nurses, compared with employees in other occupations. More information is needed about predictors of sick leave among health care workers. The aim of the study was to assess whether self-reported factors related to health, work and leisure time could predict
The spatial distribution of genetic markers can be useful both in estimating patterns of gene flow and in reconstructing biogeographic history, particularly when gene genealogies can be estimated. Genealogies based on nonrecombining genetic units such as mitochondrial and chloroplast DNA often consist of geographically separated clades that come into contact in narrow regions. Such phylogeographic
We evaluated asthma control and medication use 5 years after introduction of an inhaled corticosteroid (budesonide via Turbuhaler(R)) in 462 patients with persistent asthma and symptoms of different duration. An early treatment group with symptoms for <2 years (group A) was compared with a delayed treatment group (group B) (median duration 5 years and 3 months). Most patients received budesonide 4
We present a simple model for the arterial part of the cardiovascular system, based on Poiseuille flow constrained by the power dissipated into the cells lining the vessels. This, together with the assumption of a volume-filling network, leads to correct predictions for the evolution of vessel radii, vessel lengths and blood pressure in the human arterial system. The model can also be used to find
Det påstås att organisationer som får sin finansiering från en marknad har ett tydligt krav på att anpassa sig efter kundernas behov. Erbjuder de tjänster och/eller produkter som ingen vill ha går de på kort sikt med förlust. Om inget görs väntar på längre sikt konkurs. Långsiktig överlevnad handlar för dessa organisationer om att över lång tid erbjuda det som kunder av olika anledningar anser sig
