The transportation sector is the only sector of the Swedish society that is still increasing the emissions of carbon dioxide and other green house gases. Diesel fuel represents one of the fuels that contributes to these emissions and the use of diesel fuels is increasing every year. The main purpose of this study was to make an estimation of the current business situation for producers of liquid diesel biofuels in Sweden such as biodiesel, synthetic diesel and crude tall diesel and examine the forces of competition of the industry today and its future prospects. The study revealed that the rivalry among the existing firms was low mainly due to the geographical spread of the companies. Moreover the success of the biodiesel industry was influenced by a long-term guarantee of the tax exempt for biofuels and by the price level of petroleum diesel.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionTitle: Can nutritional support contribute to the healing of pressure ulcers in elderly patients?Author: Anton Kinnander, Sandra SmidelikSupervisor: Elisabet RothenbergExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 12-04-11Background The number of elderly patients with co-morbidity is increasing in the western world. It is therefore reasonable to predict increasing incidence and prevalence of pressure ulcers. One study, published 2009, found that as many as 59 % of geriatric patients within the Swedish health care system had developed pressure ulcers. Symptoms vary from mild erythema to severe deep tissue damage and development of pressure varies from hours to weeks.

Research suggests that society's vulnerability to natural disasters along coasts could increase as a result of climate change, which is likely to lead to elevated sea levels and possibly an increase in the occurance of meteorological phenomena such as storms and tropical cyclones. Following the Indian Ocean tsunami disaster in 2004 and Hurricane Katrina in 2005, both of which received considerable media attention, empirical data has indicated that coastal vegetation might be able to protect and reduce damages to coastal communities during tsunami events and tropical cyclones.The aim of the essay has been to study the function of coastal ecosystems as protection against tsunami waves and storms from a risk management perspective, meaning that I have, through an overview of scientific articles, compiled current research on how coastal ecosystems can attenuate storm surges and tsunami waves, and analysed how this knowledge can be put into practice in coastal communities from a risk management perspective, i.e. if coastal ecosystems are a viable risk reduction measure, are practically applicable, and if so, how they could be applied.There is empirical evidence suggesting that coastal ecosystems, particularly mangroves, can reduce the strength of a tsunami wave, but full scientific consensus on this issue has not yet been reached. With regard to protection against storm surges, there is extensive scientific evidence that coastal vegetation can mitigate damages and reduce the height of a storm surge, although the wave has to traverse several kilometres inland through thick vegetation for the protection to be effective. A synthesis in the form of a figure regarding the many physical factors that influence wave development through coastal ecosystems has been created in an attempt to simplify and explain the phenomenon.The conservation and restoration of coastal ecosystems can be justified from a risk management perspective, but planting new forest belts for the purpose of disaster mitigation is quite unrealistic and can rarely be sustainable, since, for protection to be effective, the forest belt must extend several kilometres inland from the coast, and would thus likely prove difficult to implement along coastal societies..

My work deals with large scale design of the urban fringe. The thesis is divided in three parts; ?Current viewpoints?, ?Infra City ? conditions ? and ?Infra City ? project?. In the first part, I go through the history of trade shortly. Then I discuss the concept of nature, which ends up in a linkage between natural science and aesthetics in landscape architecture. The link between those two makes a project stronger and more multifunctional. The object of my case, Infra City, is a mall situated north of Stockholm on both sides of the E4 motorway going to Arlanda airport.

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Context: During the 21st century several alarming reports have been published that deals with the depletion and pollutant of the earth by human interference. The earth is an ending resource and so are the mountains and bedrocks which are continuously mined in order to harvest its minerals. The idea behind Urban Mining is to (re)invent processes enabling further purpose for materials both from old deposits and new products providing secondary raw materials and energy. This thesis aims to investigate the challenges and opportunities of how firms and organizations can and will be able to strike a better balance between product-/service systems, economic growth and environmental stewardship in the context of Urban Mining as an approach. With the innovation of processes, technology, business- planning and creation in focus.Objective: How to future proof a business model for Urban Mining by the usage of business model design.Method: This thesis will be conducted using a case study approach, meaning that it will incorporate qualitative, exploratory and descriptive characteristics - aiming towards enabling both applied and fundamental research.Results: The result evaluates the business model element differences between traditional C&D industry and Urban Mining industry.

The purpose of this bachelor?s thesis is to examine how students at Högskolan i Borås experience the web-scale discovery service Summon, based on the theoretical model of ?The Five Dimensions of Usability?, defined by Whitney Quesenbery. The study aims to answer the following research questions: How do the students execute search assignments in the Summon interface? How intuitive and easy to navigate is the system from a user perspective? What are the students? opinions about Summon, regarding usability?Five students with varying information seeking skills are asked to perform search assignments during controlled observation, followed by semi-structured interviews. Our findings are presented in the context of previous research and show correspondence with the results of related studies.

Barn födda för tidigt (gestationsålder, GA < 37) löper ökad risk för kognitiva nedsättningar, emotionella problem och beteendeproblem. För att undersöka möjliga skillnader och samband beträffande kognitiv nivå och beteendeproblem jämfördes testresultat från Wechsler Intelligence Scale for Children (WISC-IV) och Child Behavior Checklist (CBCL) mellan för tidigt födda barn (PT) (n= 51, GA 22-34) och barn födda efter fullgången graviditet (FT) (n=57, GA 40 +/-2), i åldern 7-8 år. Alla barn var normalfungerande utan känd utvecklingsavvikelse och/eller hjärnskada. Resultaten visar att barn födda i GA 22-34 presterade signifikant sämre på verbalt (VFI) och perceptuellt funktionsindex (PFI) och erhöll en lägre helskaleintelligenskvot (HIK) jämfört med barn födda FT. En signifikant positiv korrelation uppvisades mellan GA och HIK men inte mellan GA och totala beteendeproblem.

The main purpose of the present study was to collect Swedishnorm data for the comprehension scale of the Reynell DevelopmentalLanguage Scales (RDLS III) for the ages of 4:6-4:11.

The study aims to give a description of the conditions in which matters is prepared withinSwedish Government`s offices, to describe the adaptive capacity in the agency`s internalprocesses by investigating the experiences of some civil servants restricted to the Ministry ofEnterprise and the Ministry of Environment in their work with the EU Maritime Policy GreenPaper. The results have been analyzed against the basis of eight identified criteria of buildingadaptive capacity in socially dominated systems. The criteria are comprised of both individualand organizational abilities. Only two of them were fully met; the criteria about diversity inexperiences and knowledge and the criteria about information and how the information hasbeen applied. However, the process has traces of all the identified criteria.

Socialt stöd bidrar till mindre risk för yrkesrelaterad utbrändhet. Var tredje lärare uppvisar inom sina första arbetsår symptom på utbrändhet. Syftet med föreliggande studie var att undersöka samband mellan socialt stöd och utbrändhet hos grundskolelärare. Totalt deltog 71 respondenter i Stockholm via enkäter. Socialt stöd mättes via Berlin Social Support Scale och utbrändhet mättes med Shirom Melamed Burnout Measure.

Många hushåll och individer har i dagens samhälle tvingats börja pendla till sina arbeten bl.a. på grund av en förändrad arbetsmarknad. Syftet med föreliggande studie var att se om individer som pendlar regelbundet har ett lägre KASAM. Utgångspunkten var att individer med en mer extern kontrollokus ofta har lägre KASAM och att pendling hypotetiskt sett bör påverka individen lokus i en extern riktning. Sammanlagt 27 försökspersoner i åldrarna 22 ? 50 år undersöktes med hjälp av KASAM test och I-E test.
