Popular Abstract in Swedish Mycket få människor omkring oss vet innebörden av ordet kavitation, förutom de som såg filmen "The Hunt for Red October" och kan relatera kavitation till Sean Connery i en ubåt. Kavitation motsvarar bildandet av bubblor, som kan likna kokande vatten i en kastrull. Men den uppstår inte på grund av en hög temperatur utan på grund av ett lågt tryck. Den finns i de flesta t
This dissertation examines contemporary politics targeting people with intellectual disabilities. Since this group first emerged, under labels such as ‘idiocy’ and ‘mental deficiency’, around the turn of the 20th century, its members have been seen as lacking the capacities necessary for citizenship and full societal belonging. For the last forty years, however, liberal democracies and internation
A significant part of the cost of a construction project, up to 90%, consists of purchased goods and services. Suppliers thereby have a large impact on the quality, price and time of projects. Purchasing management is therefore important for the outcome of a project. The aim of research covered by this thesis is to describe and analyse purchasing management and its interrelation with the supplier
Kisel är ett vanligt förekommande grundämne som gärna bildar en oxid, nämligen kiseldioxid. Kiseldioxid träffar man i hög utsträckning på i det dagliga livet. Det är nämligen huvudbeståndsdelen i sand, glasvaror, kvarts, många keramiska material men också i den färgskiftande ädelstenen opal. Det finns också flera grupper av porösa kiseldioxidmaterial, till exempel så kallade zeoliter som har myckeThe formation process of porous silica materials is an intricate process, involving a number of components that interact to form a highly organized material. Both zeolites and mesoporous silica materials typically require the presence of organic structure director agents (SDAs) around which the silica network polymerizes. For zeolites the SDAs are molecular and for mesoporous silica the SDAs assem
Imitation is a cornerstone in human development, serving both a cognitive function (e.g. in the acquisition and transmission of skills and knowledge) and a social-communicative function, whereby the imitation of familiar actions serves to maintain social interaction and promote prosociality. In nonhuman primates, this latter function is poorly understood, or even claimed to be absent, yet the evid
Given the strong coupling between the carbon (C) and nitrogen (N) cycles, there is substantial interest in understanding how N availability affects C cycling in terrestrial ecosystems, especially in ecosystems limited by N. However, most studies in temperate and boreal forests have focused on the effects of N addition on tree growth. By comparison, less is known about the effects of N availability
Second-generation ethanol from lignocellulose is a sustainable alternative that can partially replace fossil fuels. To be competitive with first generation ethanol from sugar and starch crops and fossil fuels, the conversion efficiency and ethanol yields of second-generation ethanol conversion processes must be improved. Improving the performance of the fermenting microorganism and efficiently con
This study evaluated the effects of a predialysis patient education programme on functioning and well-being in 28 uraemic patients. The programme consisted of four group sessions with the following themes: renal disease and dietary restriction, active renal replacement therapy, physical exercise, and the impact of chronic renal failure on economy, family and social life. Three to 9 months after ha
Background: Hyperlipidaemia is a major risk factor for cardiovascular disease, and atherosclerosis is the underlying cause of both myocardial infarction and stroke. We have previously shown that the Pro251 variant of perilipin-2 reduces plasma triglycerides and may therefore be beneficial to reduce atherosclerosis development. Objective: We sought to delineate putative beneficial effects of the Pr
This paper presents a method to grasp objects that cannot be picked directly from a table, using a soft, underactuated hand. These grasps are achieved by dragging the object to the edge of a table, and grasping it from the protruding part, performing so-called slide-to-edge grasps. This type of approach, which uses the environment to facilitate the grasp, is named Environmental Constraint Exploita
