Inadequate insulin secretion is a central component in the development of Diabetes Mellitus, resulting from reduced pancreatic β-cell mass, as well as diminished β-cell function. Islet produced 5-hydroxy tryptamine (5-HT) is suggested to regulate insulin secretion and β-cell mass in rodents during pregnancy and in metabolically challenged states. However, the role of 5-HT in control of insulin rel
This thesis starts with a review of different biodiversity assessment methods in forests and the rest deals with the metapopulation ecology of Osmoderma eremita, a threatened beetle living in hollow trees. I concentrate on the effect of dispersal, habitat quality and habitat history for the presence, population size and future survival of this species. Dispersal was studied by using both capture-m
Unsaturated solute transport is highly variable and therefore difficult to predict. In semi-arid areas, where water resources are limited, the presence of macropores is of great importance for crop production. The bromide ion (Br-) and dye tracers are useful for studies of water movement. One approach to describe the heterogeneous solute transport is to apply the concept of fractals to a dataset.
Abstract Inbreeding (selfing) was investigated already by Charles Darwin, who wanted to understand why outcrossing (non-selfing) is the predominant mating choice in the kingdom of plants. He found that inbreeding often results in less viable and fertile plants compared to outcrossing, what is known as inbreeding depression, and can be explained with increased homozygosity in the inbred, making the
Spurred on by pressure to find sustainable energy production alternatives to fossil fuels, many industries have been acquiring land in order to plant crops for biofuel production. In Tanzania, biofuel development is in an early stage, and over the last decade, several foreign actors have tried to start up biofuel projects in the country (without success). Land acquisitions are seen by many as a fo
Utsagor från vittnen är ett väsentligt inslag i en effektiv rättskipning. Hot och våld mot vittnen utgör därför ett stort hinder i det brottsbekämpande ar-betet. Om det allmänna inte kan erbjuda vittnen ett tillräckligt skydd vid så-dana angrepp, finns det risk att vittnen väljer att inte samarbeta med polisen, vilket i sin tur kan få till följd att grova brott förblir ouppklarade. I denna studie Statements by witnesses are an essential element of the efficient administra-tion of justice. The occurrence of serious forms of threats and violence to-wards witnesses and their relatives therefore constitutes a major impediment to the work in combating crime. If the public cannot offer witnesses suffi-cient protection from attacks, there is a risk that they will choose not to co-operate with the
Great efforts have been made to find solutions to the shortage of organs, such as extending the donor pool by accepting so-called marginal donors and development of transplantation of organs from animals (xenotransplantation, xt). Due to the scarcity of organs, there is a long tradition of prioritizing among patients on the waiting list for transplantation. Rules for allocation of organs have been
In this report, the technical and economical feasibility to produce higher alkanes from bio-glycerol has been investigated. The main purpose of producing this kind of chemicals would be to replace the fossil LPG used in upgraded biogas production. When producing biogas and exporting it to the natural gas grid, the Wobbe index and heating value does not match the existing natural gas. Therefore, th
Importance: Phase 3 trials of successful antiamyloid therapies in Alzheimer disease (AD) have demonstrated improved clinical efficacy in people with less severe disease. Plasma biomarkers will be essential for efficient screening of participants in future primary prevention clinical trials testing antiamyloid therapies in cognitively unimpaired (CU) individuals with initially low brain β-amyloid (
''Vetting'' is the general name used to describe the oil and chemical companies' process of selecting ships for their cargoes. This is a process which is not entirely harmonized and which has not been described or treated to any greater extent in literature, especially not from a legal point of view. This thesis therefore has several purposes, both legal and purely descriptive

I Sverige finns det en nödvärnsrätt som ger en person rätt till ansvarsfrihet när denna försvarat sig mot ett brottsligt angrepp på sin person. Denna rätt har dock kritiserats för att vara utformad att fungera bättre i typiskt sett manliga våldssituationer, d.v.s. då en man attackeras av en annan för honom okänd man. Situationer då den fungerar sämre har ansetts vara då kvinnor använt dödligt våld
Rättspraxis från senare år har aktualiserat frågan vilken betydelse bl.a. köp-lagen och allmänna obligationsrättsliga principer kan få vid tolkning av entreprenadavtal. Syftet med uppsatsen är att undersöka om bedömningen av vad som utgör fel i entreprenad enligt standardavtalet ABT 06 kan påverkas av beställarens befogade förväntningar. Tre vägar för att ge ABT 06 ett sådant innehåll undersöks –
Syftet med examensarbetet är att ta reda på hur delning av lokaler fungerar idag och undersöka potential samt de utmaningar som föreligger för att kunna etablera delningsekonomi inom fastighetsbranschen. Studien har främst fokuserat på det befintliga fastighetsbeståndet i Sverige. Syftet uppnås genom att besvara följande två frågor: 1. Hur används delningsekonomi inom fastighetsbranschen idag? 2.
Miljö- och klimatfrågor blir alltmer aktuella i samhället. Såväl konsumenter som företag och internationella organisationer lägger större fokus på dessa frågor. Exempelvis använder företag ofta miljöpåståenden i sin marknadsföring, det vill säga påståenden som skapar intrycket att en produkt har en positiv inverkan, saknar inverkan eller har en mindre inverkan på miljön än andra produkter. DärtillEnvironmental and climate issues are becoming increasingly relevant in society. Both consumers and companies, as well as international organizations are placing greater focus on these issues. For example, companies often use environmental claims in their marketing, making statements that create the impression that a product has a positive impact, no impact or a lesser impact on the environment com
Vinstsyftet är aktiebolagets mest grundläggande handlingsnorm och sätter begränsningar för vilka beslut som får tas av en bolagsledning och vilka intressenter man får beakta. I en värld med ökat institutionaliserat och internationellt ägande av företag kommer detta ofta i konflikt med lokala intressenter. Trots denna underliggande problematik och vinstsyftets roll som en av grunderna för aktiebolaThe purpose of a corporation is to maximize profit for its shareholders, and constitutes the most fundamental governing norm for a corporation. As such the corporate purpose sets limits on what decisions a corporation can make, and who to consider when making those decisions. In a world with growing international and institutional ownership of corporations, this often leads to conflict with the in
An LSS resident has been built, a resident with users that suffers from mental disabilities, a passive house by Karnfastigheter. In this project the technology of the passive house concept has been applied on a new area. An evaluation of the passive house Prisman 7 will show if the building works as projected. The energy values are taken from the building when it is in operational condition. The c
