The need for snow-free surfaces at squares, bus stops, platforms, car parks and sports facilities increases and at the same time energy price rise and the environment is becoming a hotter issue. The construction of the ground heating systems often lack thermal insulation under the heating pipes, which means that the heat from the pipes not only warm up the soil surface but also heats the surrounding soil. The insulation also has more features, by insulating the risk of frost damage is minimized. The goal of this report is to demonstrate the large heat loss and energy costs in the absence of insulation under the heating system.The report begins with a scientific way to study and treating the soil heating system uses, and the theory involved. Furthermore it also deals with different routing principles of heat pipes depending on the facility.All calculations are made with so called finite element method (FEM), in COMSOL Multiphysics 3,5a, where models are created with different conditions.

Furthermore, it is important to have knowledge of power structures that exist under given circumstances in a society to get an increased understanding of how to structure the health promoting work to get the highest possible benefits. People?s work life is essential to their health, since we spend a lot of time at work. The aim of this study was to find out which factors that relate to nursing staff?s health and stress level from a general perspective.

The world gets smaller and smaller and goods, services, people and information are nowadays more and more able to freely cross borders. Half of the Swedish GNP consists of export and almost 70 % of that amount is goods. Because of today?s increasing globalization the Swedish companies are now faced with both new opportunities and threats. Companies with goods which are manufactured in Sweden gets challenged by increased competition from cheap goods produced in other countries and companies can no longer afford to entirely focus on the domestic market.

During the last two hundred years many wetlands and streams in Sweden have been lowered to provide land for agriculture and forestry. Some of the coastal wetlands and streams probably served as spawning sites for certain species of fish in the Baltic Sea, but the present situation is not well known. As standardized methods to monitor fish in running waters are carried out during late summer or autumn, there is a need for methods to sample spring-spawning fish in these streams.The aim of this study was to survey the lower kilometer stretch of Hammerstaån in Stockholm, to investigate the extent to which the stream is used by spring-spawning fish. Furthermore, the study aims to evaluate a new type of survey fishing gill net calledströmöversiktsnät (SÖN). This was done by comparing the catch of fish by SÖN with that of fyke nets.

Penicillin G (benzylpenicillin) is the most commonly used antimicrobial substance used in equine medicine today. Two forms of penicillin G are available for equine use; one form is the poorly soluble penicillin G procaine and the other is the very soluble sodium salt. Although penicillin has a wide safety margin and is considered to possess a good tolerance, reactions due to side effects are sometimes encountered, which commonly is named ?penicillin-shock?. The etiology behind penicillin shock in horses is not completely understood, but the most common reason is believed to be procaine toxicity.

The Swedish government has a goal of achieving a fossil-free vehicle fleet in 2030. Heavy transport constitutes a significant part of Sweden's transportation sector and the vehicles are driven almost exclusively by fossil fuels. Siemens has developed eHighway, a concept for electric road systems enabling electrification of trucks, in order to reduce the environmental impact of heavy transports. This study aims to investigate the potential that eHighway has on transporting iron ore from the mine of Mertainen to a processing plant in Svappavaara. Electrified trucks are compared with conventional trucks, and diesel and electric trains.The evaluation was made with respect to energy consumption, environmental impact, and cost.

Syftet med den här studien är att undersöka huruvida en stor andel av intensiva grenspecifika pass utvecklade den aeroba kapaciteten hos motionärer som tränar inför Vasaloppet. Två testmetoder användes; ett maximalt laktattest på rullskidor utomhus och ett maximalt cykeltest på en cykelergometer inomhus. En utav fp genomförde ett tidstest på rullskidor på en given sträcka istället för laktattestet. Båda testerna genomfördes före och efter en 11-veckors träningsperiod som bestod av 41 procent medel- och högintensiva pass som genomfördes grenspecifikt. Det betyder intervaller på rullskidor eller i skidgång samt snabbdistanspass på rullskidor.

Käppala wastewater treatment plant situated on the island of Lidingö northeast of Stockholm is running a project during 2004 and 2005 with the purpose to map out the capacity of anaerobic digestion in the digesters that treat primary and excess sludge. The purpose of this thesis work, which is part of that project, was to characterize the present anaerobic digestion process and to investigate its capacity to treat other organic wastes such as restaurant waste and waste from water works. To decide the potential of both methane and biogas production from different substrates batch laboratory tests were carried out. To imitate the anaerobic digestion process at Käppala continuous tests with small scale reactors were carried out. These reactors were later fed with restaurant waste.The batch laboratory tests showed that primary sludge had a potential biogas and methane production of 0,62 and 0,35 Ndm3/g VS respectively after 40 days of digestion.

Bakgrund: Basala hygienrutiner ska enligt Socialstyrelsen tillämpas för att förebygga vårdrelaterade infektioner (VRI). VRI är ett hot mot patientsäkerheten och kan medföra ökat lidande för patienten och ökade kostnader för samhället.Syfte: Att undersöka följsamhet till basala hygienrutiner inom ambulanssjukvård i ett antal utvalda omvårdnadssituationer.Metod: En deskriptiv kvantitativ studie där data inhämtades genom strukturerad observation. Bekvämlighetsurval tillämpades och totalt 68 observationer gjordes på två ambulansstationer inom samma landsting.Huvudresultat: Följsamhet till basala hygienrutiner varierade, med högst följsamhet till rutinen om kort eller uppsatt hår (87%) samt till användning av handskar (87%). Lägst följsamhet observerades till rutinen om handdesinfektion före patientnära arbete eller användning av handskar (1%). Inte vid någon observation (0%) visades följsamhet till samtliga sju basala hygienrutiner som undersöktes.Slutsats: Att brister av varierande grad fanns i följsamhet till basala hygienrutiner.

The purpose of this thesis is to gain understanding of how companies proactively can manage their reputation. The thesis analyzes three multinational companies in Sweden and uses two theoretical approaches - the reputation risk view and the reputation strengthening view - to gain an overall perspective of how companies work with their reputation. It focuses on investigating which key areas of reputation risk the focal companies identify and how they manage the reputation risks within these areas. Moreover, it examines which stakeholders the companies believe are most critical from a reputation point of view and in what ways the companies work with strengthening their reputation among those stakeholders. In order to find a general approach, the thesis investigates the similarities and differences that exist between the respective companies in the study.

Namibia, southern Africa, suffers from an energy shortage and is therefore facing severalchallenging problems. The use of firewood as fuel for cooking is common in the whole countryand has negative consequences for health and the environment. This work have focused ondeveloping a solar baking oven, calledSunbaker, adapted for Namibian families needs forbaking. The development was based on classic solar cooking limitations, specific needs forNamibia and to have a feasible manufacturability.The project started with a theoretical study in Sweden where different solar cookers, informationregarding Namibia, technical aspects and end user aspects were studied. To assess the need for asolar baking oven aMinor Field Study took place in Namibia during eight weeks in July toSeptember 2009 and resulted in a product design specification.

AbstractPURPOSE: The aim of this study was to describe and compare possible differences regarding selected prognostic factors for disability between patients with non-specific chronic pain who were about to start a multidisciplinary treatment program (MMR), either within primary care (MMR1) or hospital care (MMR2).METHODS: The study had a descriptive and comparative cross sectional design. Eighty-nine patients were recruited consecutively when they were about to start their team treatment (50 in MMR1,39 in MMR2). The measurements were; Evaluation of self-reported self-efficacy for eight daily activities (STIVA-8), The Pain Belief Screening Instrument (PBSI) and Hospital Anxiety and Depression Scale (HADS).RESULTS: The study found some significant differences between the answers from patients in MMR1 and those from patients in MMR2. For instance, patients in MMR2 estimated lower self-efficacy according to STIVA-8 than patients in MMR1. Also, there were fewer low risk patients and more high risk patients in MMR2 than in MMR1 regarding pain intensity according to PBSI.

Studien undersöker Sveriges Radios nyhetspublicering på nätet och jämför med Ekots nyhetssändningar i etern. Syftet är att undersöka eventuella skillnader i nyhetsurvalet, samt hur webbinnehållet påverkas av flerkanalspubliceringen och webbens möjligheter till ständig publicering och uppdatering, möjlighet att använda sig av bildobjekt och grafik samt hypertext och interaktivitet. Undersökningen ramas in av de teoretiska begreppen konvergens och divergens, samt teorier om hur kanalernas produktionsförhållanden påverkar nyhetsinnehållet. En kombination av kvantitativ och kvalitativ innehållsanalys har använts, där de båda kanalerna undersöktes under två dagar, 23 och 24 april 2012. Det visade sig att webbens nyhetsrapportering till viss del bestod av nyheter som inte fanns med i Ekosändningarna.
