Popular Abstract in Swedish Denna avhandling presenterar en bred och kritisk översikt av litteraturen och forskningen angående inlärning av uttal och språkljud. De problem som framför allt vuxna har med att lära sig uttalet i ett främmande språk diskuteras och de olika hypotesen granskas. Jag argumenterar att inlärning är i stort sett en härmningsprocess. Två modeller av inlärning presenteras. DThis work is concerned with the acquisition of the phonetic characteristics of languages and dialects, and with the issue of learner talent or individual achievement in learning second languages. Following a survey of the literature on language learning limits, it is argued that the concentration on group trends in most of the existing literature, whilst convenient, serves more to obscure the reas

The preference of juvenile Arctic char [Salvelinus alpinus (L.)] for odors from siblings and nonsiblings with different major histocompability complex class II (MHC) genotypes was studied in two-choice fluviarium tests. In the first part of the study, test fish demonstrated no preference for water scented by a sibling with a MHC genotype different from its own versus water scented by a MHC identic

Adherence to maintenance therapy is often poor in patients with asthma. Simplifying dosing regimens has the potential to improve both adherence and asthma-retated morbidity. In this 12-week, randomized, double-blind, double-dummy, parattel-group study, 617 patients with mild to moderate persistent asthma (mean forced expiratory volume in 1 s [FEV,] 78.5% predicted) who were not optimally controlle

Popular Abstract in Swedish Kritiskt sjuka patienter på intensivvårdsavdelningar (IVA) har ofta störningar i blodets levringsförmåga (koagulation). Kliniska tecken som blodpropp (djup ventrombos eller blodpropp i lungorna) och/eller blödning kan vara resultatet av aktivering och konsumtion av koagulationsfaktorer och koagulationshämmare. Disseminerad intravaskulär koagulation (DIC, som är en samtiCritically ill patients in intensive care units (ICU) often have coagulation disturbances. Clinical manifestations such as thromboembolism and/or bleeding may result from activation and consumption of coagulation factors and inhibitors. Disseminated intravascular coagulation (DIC) is a severe condition with an often-poor prognosis. Global haemostatic tests are inexpensive, widely available, and ma

Popular Abstract in Swedish Sjukgymnaster har behandlat patienter i samband med kirurgisk behandling sedan början på 1900-talet och den dominerande uppgiften har varit att förebygga lungkomplikationer och blodproppar samt att bedöma behovet av vidare rehabilitering efter utskrivning. Den medicinska utvecklingen går emellertid snabbt framåt och sjukgymnasten har en utmanande uppgift i att utveckla The overall aim of this work was to study the influence of surgery on energy expenditure (EE) during working capacity measurements and during walking. In the first study the aim was to investigate whether two different devices were sensitive enough to reveal differences in energy expenditure during treadmill walking, and if the measurements were reproducible. It was shown that an airflow of 42.5

In the present work we report data from experiments comparing the proliferative stimuli demonstrated by Streptococcal Protein-G and Staphylococcal Protein A on human peripheral blood mononuclear cells. Protein-G and Protein-A are presented to the cells in solution as well as linked to plastic or Sepharose beads, or incorporated within the cell wall of whole bacteria. The cellular response is measu

We devise a stochastic and spatially explicit model for the dynamics of the initials cells in a stratified shoot apical meristem (SAM). The meristem is composed of three layers with seven initials per layer. We investigate the probability and number of divisions for a mutant lineage to either reach fixation or becoming purged through selection or drift. In contrast to previous studies our results

The mechanisms underlying biphasic insulin secretion have not been completely elucidated. We compared the pattern of plasma insulin changes during hyperglycemic clamps in mice to that of glucose-induced insulin secretion and cytosolic calcium concentration ([Ca2+](c)) changes in perifused mouse islets. Anesthetized mice were infused with glucose to clamp blood glucose at 8.5 (baseline), 11.1, 16.7

Popular Abstract in Swedish Förekomsten av hjärt-kärlsjukdomar skiljer sig mycket mellan olika jordbruksbaserade samhällen, medan de praktiskt taget saknas helt bland samhällen som inte är baserade på jordbruk, såsom jägar- och samlarsamhällen. När man letar efter livsstilsfaktorer som skulle kunna gynna uppkomsten av kardiovaskulära sjukdomar verkar det därför logiskt att fokusera på livsstilen iThe prevalence of cardiovascular diseases (CVD) exhibits considerable variation across agrarian societies, whereas they are virtually absent in non-agrarian societies such as hunter-gatherer and horticultural societies. When looking for lifestyle factors which could promote CVD, it therefore seems logical to focus on the agrarian lifestyle and ways in which it departs from a non-agrarian lifestyle

Tadpole density dependence has repeatedly been studied in laboratories and mesocosms, but rarely in natural ponds. The present study manipulated density in three ponds; each pond was divided into one low density section and one high density section. The experiment was run for eight years, switching density treatments within ponds among years. This experimental design cannot definitively separate t

This Letter presents a proton fast field cycling Nuclear Magnetic Resonance study of the molecular dynamics in the region above the smectic A-isotropic phase transition in thermotropic liquid crystals. The proton spin-lattice relaxation time was measured as a function of temperature at different Larmor frequencies and the experimental results were interpreted in term of the Landau De Gennes theory

The title compound, cis-[ PtCl2( C4H10S) (2)], crystallizes in the space group P21/ n with pseudo- square- planar coordination geometry. The orientation of the ethyl groups on the S atoms is staggered with respect to the coordination plane, giving the complex approximate C(2)v symmetry. The complex does not form dimeric packing units with short Pt center dot center dot center dot S intradimeric di

BACKGROUND: Hip dislocation in children with cerebral palsy (CP) is a common and severe problem. The dislocation can be avoided, by screening and preventive treatment of children with hips at risk. The aim of this study was to analyse the characteristics of children with CP who develop hip displacement, in order to optimise a hip surveillance programme. METHODS: In a total population of children w

FeSiB tapes have long been commercialised for their excellent soft-magnetic properties but do not manifest a glass transition temperature Tg as crystallisation intervenes. In this work, we present the crystallisation and properties of two Fe-based glasses, which show a glass transition before crystallisation. Using Ni and Co substitution, we can design glasses that form primary FCC or BCC FeNiCo s

Two proteoglycans differing in size and composition were isolated from human follicular fluid. The larger one of high density had a molecular mass of 3.0x10(6) Da, as determined by laser light-scattering, and was substituted with 15-20 chondroitin sulphate (CS) chains (Mr 60000-65000). Half of the CS disaccharides were 6-sulphated, whereas the remaining ones were non-sulphated. Digestion of the CS

Degradation of vegetation and soil erosion has contributed to loss of biological productivity and land degradation in Iceland. This thesis focuses on spatial and temporal patterns of land degradation in Iceland from a geographical perspective both along short and long timescales. The activity of current degradational processes has been assessed by studying farmers' perception of the problem and co

This work is a study of burial rituals in Scania during the Early Iron Age. It is based on a systematic listing of all excavated or otherwise recovered graves from the period. Grave customs can be described as varied in Scania and uniform on Zealand. The material of Zealand represents an endogamic kinship structure. Scania is interpreted as having had a stable and more traditional, patriarchal, ex
