Tardigrades are well known for their capacity to enter an anhydrobiotic state, and remain ametabolic for several years. Yet the evolutionary background, and the forces of natural selection that act on anhydrobiotic capacity have remained unexplored. In this paper, I review the basic problem of anhydrobiosis and the phenotypic traits that may be the main targets of natural selection for improved an

Objective: To investigate the association between human herpesviruses and multiple sclerosis ( MS), as well as between measles virus and MS. Methods: The authors identified prospectively collected serum samples from 73 MS cases and retrospective sera from 161 MS cases in two population-based serum bank registers. Analyses of IgG antibody responses in cases and matched referents were performed for

Exact and approximate quantum numbers of the cranked Nilsson-Strutinsky (CNS) formalism are exploited to calculate excited bands in fixed configurations with the energy of the individual bands minimized with respect to deformation for all spin values. The formalism is applied to Cu-59, where all bands which appear important in the decay out of the superdeformed band are calculated.

It is difficult to determine whether transient folding intermediates have a cooperative (or first-order) folding transition without measuring their rates of formation directly. An intermediate I could be formed by a second-order transition from a denatured state D that is progressively changed into I as conditions are changed. We have not been able to monitor the rate of formation of the folding i

Abstract in French Dans cet article j’aborderai, suite à ma thèse de doctorat, la problématique autour du récit en constellation en conversation exolingue. On appelle le récit en constellation le récit qu’un seul et même locuteur produit à plusieurs reprises en présence de locuteurs différents. Ce type de récit s’est avéré intéressant de plusieurs points de vue, notamment en ce qui concerne l’orig

Delar av den svenska träbyggnadsindustrin har stora möjligheter att utveckla det industriella byggandet. Villor har lång tradition av att prefabriceras i fabriker för senare transport och montage på byggplats. Volymbyggnadsteknik där prefabriceringen även innefattar ytskikt och installationer har ökat prefabriceringsgraden avsevärt. Fortfarande är dock tillverkningen hantverksbetonad och genomförs

The aim of this study was to assess the rate of clinical progression to early and late stages of human immunodeficiency virus-2 (HIV-2) infection. CD4 cell counts and other potential prognostic markers for disease progression were also evaluated. In January 1990 an open prospective cohort of police officers in Guinea-Bissau was initiated with yearly serological and clinical follow-up. Follow-up en

Southern Sweden is an area of Lyme borreliosis (LB) endemicity, with an incidence of 9 cases per 100,000 inhabitants. The most frequent clinical manifestations are erythema migrans (77%) and neuroborreliosis (16%). There was no record of human Borrelia strains being isolated front patients in this region before the prospective study reported here. Borrelia spirochetes were isolated from skin and c

Popular Abstract in Swedish Kring familjeproblematiken och för behandlingen av familjekonflikter har det svenska samhället organiserat olika sociala verksamheter som traditionellt regleras av Socialtjänstlagen. Familjerådgivningen är en av dessa verksamheter och definieras som en psykoterapeutisk behandling, till vilken en eller båda parter vänder sig oftast på frivillig basis när de upplever att This dissertation is the result of an evaluation of family counselling (FC) in a middle-sized city in Sweden. The findings support results from earlier studies of family counselling which indicate that people have a positive attitude to counselling. But this finding led to questions that remained unanswered in earlier research. What is it particularly in FC treatment that brings about a result, wh
