Biogas mainly consists of methane and carbon dioxide, where methane is theenergy-rich gas, and is naturally created when organic matter breaks down in absenceof oxygen, also known as anaerobic digestion. A biogas plant re-creates the anaerobicconditions inside a digester where the organic substrate is fed into and digests toproduce biogas. The gas is then used to produce energy by combustion and can beseen as a completely renewable fuel.Today, energy from biogas is used primarily by major stakeholders such asmunicipalities and thus the plants become very large with high investment- andconstruction costs. There are currently few small plants in Sweden, even though thepotential for agriculture and medium-sized to smaller farms to become self-sufficientin terms of electricity and heat is great. Farms have a natural stock of digestibleorganic material in form of manure or crops for example, which are constantlyavailable.

Syftet med studien var att undersöka explicita och implicita attityder till överviktiga människor samt om och i så fall vilken betydelse ålder, kön och vikt har i denna relation till varandra. Utifrån tidigare forskningsresultat om attityder och övervikt predicerades en skillnad mellan explicita och implicita attityder till överviktiga, där äldre har en mer negativ attityd till överviktiga än yngre, att kvinnor är mer negativa än män och underviktiga är mer negativa än normal- och överviktiga. I vår studie användes IAT (Greenwald, McGhee & Schwartz, 1999) för att mäta försökspersonernas implicita attityder och en kort version av ?Fat Phobia Scale? (Bacon, Scheltema & Robinson, 2001) för att mäta deras explicita attityder. Studien omfattade 68 försökspersoner med en medelålder på 32 år och där 31 var män (46%) och 37 var kvinnor (54%).

Heart failure is an illness that requires life-long treatment and often affects everyday aspects of a person?s life. Self-care is a significant part of the treatment. Good self-care resources make it possible for people with heart failure to make the lifestyle changes they often need to maintain or improve their level of health. Self-care means having knowledge of and being able to recognize the symptoms and signs of deterioration that can occur with heart failure, so that the person can take appropriate measures ? and it also means knowing when it is time to seek professional help.

Forestry is increasing on an industrial scale where collection of logging residues takes a greater part. This has resulted in more machinery and heavy machinery driving in the clear felled area, this increases the risk of soil damage that will occur in the form of soil compacting and rutting in the clearings. This affecting on the nature in a negative way and especially in rivers and lakes that are affected by siltation and acidification leading to increased levels of heavy metals and methyl mercury. The purpose of this study was to investigate why there is damage to the ground when working with the slash in forest management from the forest officer point of view. A self-designed questionnaire was used and 45 questionnaires were sent out to various companies all over Sweden.

Bakgrund: Akupunktur används frekvent som behandling mot smärta såväl som andra symptom exempelvis vid spänningshuvudvärk och migrän. Huvudvärk delas in i två kategorier: primär och sekundär huvudvärk. Exempel på primär huvudvärk är migrän och spänningshuvudvärk och exempel på sekundär huvudvärk är nackrelaterad huvudvärk. Fler kvinnor än män har spänningshuvudvärk samt migrän och det är vanligare desto högre utbildningsnivå individen har. Syfte: Syftet med studien var att kritiskt granska och sammanställa den vetenskapliga litteraturen gällande akupunkturens effekter på smärta och livskvalitet vid spänningshuvudvärk och migrän.

This study was conducted at the City Abattoir in Kampala, Uganda to evaluate the cleaning process, with focus on bacterial pathogens, in a pilot scale integrated bioprocess. This consisted of four steps: anaerobic sequencing batch reactors; aerobic/anoxic sequencing batch reactors; a high performance temperature controlled methanogenesis digester and a constructed wetland. The objective was to determine if this type of cleaning process could be used to clean wastewater from abattoirs in a satisfactory way. The indicator organisms for faecal contamination, Escherichia coli and Enterococcus spp. were used to investigate in what numbers bacteria could be found in the untreated wastewater and how much that was reduced in the different steps of the cleaning process. The water was analysed for Salmonella to see if human pathogens could be found and could survive the different steps of the treatment process.

AbstractThe purpose of this study was to investigate students' perception of their grades in relation to the grading criteria in physical education. To investigate this used issues: how values and experience rating criteria? How do students their teachers' planning of lessons? How do students grading assessment in physical education and what they believe is important? The method used was a questionnaire with closed questions. The answers were given on a six-point scale, ranging from 1 = "not true" to 6 = "totally agree". In a qualitative analysis of the quantitative material.

The park at Svaneholm is a place, the history of which is very little known today and the needfor better knowledge has been the cause of this investigation. The essay is primarily limited tothe time from late 17th century up to the end of the 18th century and takes stand on profoundinvestigations in accessible map-and archive material. The results presented show a manorhill, which during the course of a hundred years was subject to several changes and in bigparts consisted in other than park/garden.Burman related to the manor hill containing a cowshed, a large dam and a parterre garden isix quarters and it is plausible to think, that this establishment generally was built as producedon the plate.In the 18th century the construction is being changed, they go on building at the cowshed andin 1707 there are totally 268 livestock on the farm. In 1723 the garden is represented in amuch bigger scale than on the plate from the 1680:s, but it is not possible to tell, whether it isnew or not.Parts of the parterre garden is remaining during the whole of the 18th century, for the leastuntil it is being squared, but on two of the squares there was built a riding-groundMoreover the cowshed burnt down and was only partially reconstructed.The image given by the archive material is at the same time variegated. The inventory list ongarden tools from 1726 gives an image of gardening more directed to growing and pathshuffling, while the possibilities of keeping the parterres were fewer (e.g.

Background: Testosterone is the most important androgenic hormone in the male. Aging is closely associated with reduction of serum testosterone which can lead to reduced muscle mass, muscle strength, bone density, and depression. These symptoms may be counteracted by administration of testosterone. Objective: The purpose of this study was to examine the effects of hormone replacement in men with age-related testosterone deficiency. Method: We performed a systematic review using Randomised Controlled Trials (RCT).

The scope of this project is to make a comparison of costs associated with wind and nuclear power in order to decide which one of these is the most suitable in the case of an increased demand for electricity. It is also investigated if there are other factors that can influence the choice of energy source.An average cost is calculated in terms of kronor per kilowatt-hour (SEK/kWh) using cost of investment, operation & maintenance and taxes & subsidies. Total investment cost is recalculated to production cost using the annuity method at three different interest rates (6%, 9% and 12%).The comparison is made between three cases of wind power and two cases of nuclear power. For wind power there are two ocean-based (300MW and 100MW installed capacity, respectively) and one land-based (60MW) wind farm. For nuclear power there is one EPR-reactor (1600MW) and one AP1000-reactor (1100MW).

Bakgrund: Brand personality beskrivs i litteraturen som den uppsättning avpersonliga egenskaper som beskriver ett varumärke, genom att försevarumärken med mänskliga drag kan konsumenten lättare relatera ochknyta an till sina egna preferenser utifrån sin egen karaktär (Aaker 1997).Det var år 1997 som forskaren Jennifer Aaker (1997) kom med denförsta definitionen om brand personality, som följde "the set of humancharacteristics associated with a brand" (Aaker 1997, p 347).Syfte: Syftet är att förklara hur Aaker?s (1997) modell brand personality ?thebig five? kan revideras för att passa till den Svenska kontexten.Forskningsfråga: Vilka dimensioner i modellen brand personality ?the big five? (Aaker,1997) behöver revideras för att appliceras i en Svensk kontext?Vilka personlighetsdrag och dimensioner är unika för den svenskakontexten och behöver därmed adderas till brand personality modellen?Metod: Denna studie har antagit en abduktivt angreppssätt, där tidigareforskning om brand personality har varit utgångspunkt. Författarna toggrund i befintlig teori med avsikt att testa modellen ?the big five? skapadav Aaker (1997) empiriskt i en ny kontext. Till studien tillämpadesfokusgrupp (förstudie) och enkät.Resultat och slutsats: Genom studien var det möjligt att fastslå att Aakers (1997) ursprungligamodell brand personality, inte var funktionell i den kontext som studienämnar.

By using the cyborg as a structural tool to analyze certain aspects of human interaction with what can be perceived as landscape or landscape architectural elements, this thesis seeks to explore the concept of the cyborg landscape in order to place human practice in the context of postmodern ideas of the end of true nature. Ever since human kind has externalized evo-lution by using tools and extending the body with technological inventions, we have also taken our surroundings out of their natural trajectory. Everything we do that is conditioned by the use of technology is altering that which we perceive as nature and natural. Since we have been doing this for millennia we have of course also altered our surroundings by the influence of technology.This thesis uses three examples of landscape or landscape architectural elements that are conditioned by the integration of technology to explore this practice through a postmodern model of analysis based on the concept and basic premises of the cyborg, or the cybernetic organism. A cybernetic organism is in short an organism that has functioning technological parts integrated into its system.

Aim: To investigate if physical exercise in combination with coaching will reduce pain and improve knee function in patients with mild to moderate osteoarthritis in the knee compared to physical exercise alone.Method: The study consisted of 42 patients who were randomized to either an intervention group or a control group. Both groups followed a standardized training program at home, but the intervention group received additional support with regard to the aim of their training, as well as extra coaching during the training period of ten weeks. A Visual Analog Scale (VAS) was used to evaluate the patients? pain. A 10 metre walking test, the Index of Muscle Function (IMF) and the Knee injury and Osteoarthritis Outcome Score (KOOS) were also used to evaluate knee function.

Bakgrund: Subaraknoidalbl?dning ?r en allvarlig och potentiellt livshotande hj?rnbl?dning som kr?ver intensivv?rd. Traditionellt har dessa patienter h?llits i s?ngl?ge p? grund av risken f?r komplikationer, trots att det saknas evidens som st?der denna praxis. Tidig mobilisering anv?nds inom intensivv?rden f?r att minska komplikationer och f?rb?ttra ?terh?mtning, men dess effekter p? patienter med subaraknoidalbl?dning ?r inte tydligt kartlagda.
