Det finns en ganska stor samstämmighet bland forskare och också bland många planerare att en rad åtgärder behövs för att transportsystemet skall kunna anpassas till miljömålen. I den här studien har vi undersökt hur olika bebyggelseparametrar påverkar resandet och energianvändningen. Flertalet studier inom området har fokuserat på stora städer. I vår studie har vi analyserat orter i Skåne. Syftet
Glucagon secreted by pancreatic α-cells plays an important role in the regulation of blood glucose. In this thesis, different techniques such as electrophysiology, immunohistochemistry and hormone secretion assay were combined to explore the mechanisms by which glucagon secretion is regulated. Like pancreatic β-cells, which produce insulin, α-cells are electrically excitable and equipped with dif
This paper contains the discussion inputs by the contributors of the special issue on the subject of rogue waves.
Maternal smoking during pregnancy has been reported to negatively impact sperm counts of the sons. Sufficient data on the effect of paternal smoking is lacking.
The literature on regional innovation systems has considerably enhanced our understanding of the critical role played by geographical proximity and local institutional conditions for the production of new knowledge and its economic exploitation. In most cases, however, both theoretical and empirical work has focused on regional innovation systems situated within a national context. Little research
Laminar burning velocities of four biomass derived gases have been measured at atmospheric pressure over a range of equivalence ratios and hydrogen contents, using the heat flux method on a perforated flat flame burner. The studied gas mixtures include an air-blown gasification gas from an industrial gasification plant, a model gasification gas studied in the literature, and an upgraded landfill g
Background: As more people reach older age, there is a growing interest in improving old person's health, activity, independence and social participation, thereby adding quality to the extended years. Preventive home visits (PHV) programs for old people have received much attention in recent decades. A large body of research shows mixed effects, and argues that a home visit is a complex social pro
We report on the status of the Baltic/Wadden Sea flyway Eider population based on trends in breeding and wintering numbers throughout the region, supplemented by changes in the sex ratio and proportion of young Eiders as monitored in the Danish hunting bag. At the flyway scale, total numbers of breeding pairs decreased by 48% during 2000-2009, after relatively stable breeding numbers in 1991-2000.
Objective: to describe the experiences of immigrant parents of an ultrasound examination in the second trimester of pregnancy, highlighting information, communication, thoughts, feelings and well-being. Methods: An exploratory, qualitative study using in-depth interviews with parents separately. Content analysis was used. A total of nine Farsi-speaking couples, in all 18 persons, who now live in S
Motivated by growing considerations of the scale, severity, and risks associated with human exposure to indoor particulate matter, this work reviewed existing literature to: (i) identify state-of-the-art experimental techniques used for personal exposure assessment; (ii) compare exposure levels reported for domestic/school settings in different countries (excluding exposure to environmental tobacc
Excitation and emission polarization dependence of fluorescence intensity of single LH2 complexes from Rhodopseudomonas acidophila 10050 and Rhodobacter sphaeroides is reported. The results are presented as two-dimensional polarization plots and interpreted in terms of tilted light harvesting complexes indicating that sample preparation leads to partially oriented LH2 cylinders. An alternative exp
Spelifiering inom utbildning är ett väldigt aktuellt ämne idag och det pågår mycket forskning och många projekt för att undersöka hur spel främjar lärande.
The pedestrian safety problem is huge in all developing countries. The main aims of the project are therefore: 1/To understand pedestrian safety problem in a developing country, 2/To identify feasible traffic calming measures. International experiences were complemented by field studies at seven sites in the city of Jaipur. A wide range of field studies were made, out of which traffic conflict stu
In this review, starch behavior is described from molecules in solution to the use of starch in products. The determination of molecular characteristics with asymmetrical flow field-flow fractionation is described, and the behavior of starch in binary solutions is discussed. The organization of starch in granules and the changes in organization during gelatinization and retrogradation are then des
