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
An east-west regional gradient in cardiovascular mortality was found within seven counties in mid-Sweden during the years 1969-1983. The mortality differences were of considerable magnitude for ischaemic heart disease (IHD) as well as for stroke. In previous reports, in which the distribution of risk factors among middle-aged men was presented, the moderate variation among the communities could no
Popular Abstract in Swedish Fartygsgenererade vågor ofta orsakar större kustförändringar jämfört med vindvågor utmed stränder där stryklängden är begränsad. Med bakgrund av att fartygstrafiken, särskilt från höghastighetsfärjor, och dess potentiella miljöeffekter har forskning inom detta område ökat. Fast att ett antal studier har och fortsätter undangöras, forskning om fartygsgenererade vågor ochIn navigable waterways, owing to the relatively short fetches for wind wave generation, the free waves generated by moving vessels often produce the dominant wave action with respect to erosion of the shore. In response to the fairly recent introduction of high-speed ferries, combined with a planned expansion within the passenger- and car-carrying ship market, the need to model and predict coastli
