Popular Abstract in Swedish Tarmslemhinnans förmåga att ta upp olika näringsämnen från tarmen är essentiell för vår överlevnad men den utgör också en viktig skyddsbarriär mellan tarminnehållet och blodbanan. Tarminnehållet består till stor del av bakterier och ej nedbrutna födoämnesmolekyler vilka kan ge upphov till patologiska tillstånd om de passerar tarmväggen. Ökad kunskap om tarmens funktion The intestinal epithelium has the dual function of absorbing nutrients and water as well as being a barrier to potentially harmful substances such as macromolecules and bacteria. In the present thesis the barrier function of the intestinal mucosa was studied in vitro in Ussing diffusion chambers. Intestinal permeability to different-sized molecules was investigated and compared in various intesti

The infrastructure for the third generation of mobile telephony, UMTS, is under construction in Sweden. Within three years four operators were to build competing systems to cover 99,98 % of the population. The case of the 3G infrastructure illustrates how the sustainability issues are handled in planning and environmental management, with conflicting goals between institutional levels and compet

Popular Abstract in English Malnutrition and micronutrient deficiencies continue to be a major health problem, especially in rural areas in developing countries. It is of great importance to have reliable data about the existing deficiencies, and also about their main causes, for the designing and developing of efficient nutritional strategies in order to overcome nutritional problems. Bolivia is While originally, protein-energy deficiency was considered the main factor of malnutrition, it is now understood that micronutrient deficiencies play a fundamental role in a variety of health and disease outcomes. Zinc and iron deficiencies are still highly prevalent in low-income countries, whereas insufficient intakes and diets with low mineral absorption are the major causes. Sustainable and fe

Popular Abstract in Swedish En majoritet av sk förlossningsskador med tecken på syrebrist i hjärnan uppstår troligen inte i samband med förlossning utan inträffar under graviditeten, ofta av okänt ursprung. Förlossningen är dock en stressituation med ökat krav på god blod- och syretillförsel till fostret. Övervakning med kardiotokografi (CTG) under förlossningen har inte påtagligt förändrat antaleThe studies upon which this thesis is based were designed to evaluate normal fetal and neonatal adaptation and the effects of obstetrical interventions during labor and delivery on fetal and neonatal cerebral circulation. Non-invasive Doppler ultrasound was used to record blood flow velocities from the middle cerebral artery (MCA) both antenatally from the fetus, and from the newborn in the early

The aim of this thesis was to study maternal emotional impact on the fetus and on pregnancy outcome. The thesis comprises five papers, which emanate from a prospective study regarding life situation, the experience of pregnancy, anxiety (Spielberger State-Trait Anxiety),and life events in nulliparous women, conducted in Malmö during 1988-1989. Examinations of fetal hemo-dynamics, fetal movements,

MASTER (MAnaging Speeds of Traffic on European Roads) aims to provide recommendations for speed management strategies and policies and to elaborate guidelines for the development of innovative speed management tools. Within the framework of the project, field trials with a car equipped with a speed limiter were carried out in three “regional typical” European countries: Sweden, the Netherlands, an

Popular Abstract in Swedish EG-fördragets regler om varors fria rörlighet är ett centralt område inom de Europeiska gemenskapernas rättsordning. Detta rättsområdet har stor betydelse i det praktiska rättslivet, såväl för offentlig förvaltning som för enskilda företag. I denna bok behandlas spörsmål rörande EG-fördragets regler om icke-tariffära handelshinder (artiklarna 30, 34 och 36). Ända sedanThis thesis concerns the Articles 30, 34 and 36 of the EC-Treaty and conflicts of competence between the Community and the Member States. It deals especially with the delimitation between community concerns and national concerns in the field of non-tariff barriers to trade in community law. A new perspective concerning the application of Articles 30 and 34 of the EC-Treaty is introduced. It is arg

The issue of participation is of interest to scholars in law because of its relation to new forms of governance and regulation (Black 2000, 2001; de Burca and Scott 2006). Empirical studies of participation in biotechnology licensing show however that such procedures “itself may cause serious trouble when it is embedded in a formal procedure with a relatively strong legal framework.” (Bora & H

We discuss mass transfer in eccentric binaries containing a white dwarf and a neutron star (WD-NS binaries). We show that such binaries are produced from field binaries following a series of mass transfer episodes that allow the white dwarf to form before the neutron star. We predict the orbital properties of binaries similar to the observed WD-NS binary J1141+6545, and show that they will undergo

Popular Abstract in Swedish Inflammatoriska luftvägssjukdomar såsom astma och rinit är några av de folksjukdomar som trots den moderna läkarvetenskapen uppvisat en ökad prevalens de senaste decennierna. En allergisk reaktion och efterföljande inflammation tros ligga bakom många av de förändringar som karakteriserar astmatiska luftvägar tex infiltration av vita blodkroppar och extravasering av plasEpithelial damage may contribute to the pathology in airway diseases such as asthma and rhinitis. However, the distribution of epithelial shedding in inflammatory airway diseases and, particularly, the ensuing repair processes are largely unknown. In the present studies we have developed novel in vivo techniques to explore epithelial repair mechanisms and associated tissue responses occuring in gu
