A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

To be able to evaluate different radio waveforms in a laboratory environment FOI in Linköping has developed an experimental system for radio communication called Rasmus. The system consists of a transmitter, a channel emulator and a receiver. The transmitter modulates a digital signal to a desired analogue waveform. The channel emulator is used to simulate a real radio channel. The channel emulator distorts the signal by splitting it up in several propagation paths.

The purpose of this study was to examine how small-scale private forest ownersmake decisions regarding pre-commercial thinning. In 2015 it is ten years agosince the storm Gudrun hit the southern parts of Sweden and now large areas arein need of pre-commercial thinning. This study is built upon qualitativeinterviews with seven small-scale private forest owners with forest properties inthe county Kronoberg. The respondents were chosen by the modelSKOGSÄGARPROFILENTM (forest owner profile).The results of the interviews showed that five categories: ownership, the stormGudrun´s impact, silviculture, forestry contacts and driving force was important.How will their purpose and aim affect the pre-commercial thinning? Personalinterests, and expectations of the next generation to take over, are purposes thisstudy has found.

The production of ferrochromium alloys at Vargön Alloys AB contributes to formation of unwanted ferrochromium dust, which contains toxic Cr(VI). The dust is since summer 2005 treated with an iron-sulphate solution to reduce Cr(VI) to the non-toxic Cr(III). A year later the treatment technique was improved and disposal occurs in cells on the landfill. The cells can be up to 300 m3 and the edges can be made out of fro example concrete. Tests are conducted on the treated dust when it is disposed.

Nackbesvär är ett samhällsproblem både gällande välmående och indirekt en kostnad för samhället. Gällande ett års incidens av nackrelaterade besvär har Skandinavien högre medelvärden än övriga länder i Europa och fler kvinnor än män drabbas. Vid screening av nackbesvär med en multidimensionell inriktning baserad på en biopsykosocial modell finner man grupper med bristande motorisk kontroll. En av dessa grupper har felaktigt motoriska kontroll mönster exempelvis på ett sådant är en framåtskjuten huvudhållning. Syftet med studien var att undersöka effekterna av motorisk inlärning vid dysfunktionell postural hållning hos personer med långvariga nackbesvär.

Hammarby Sjöstad is a new district of southern Stockholm built with focus on reduced environmental impact by recirculation of materials and sustainability. The environmental goals aim to cut the water consumption by half and a separate storm water treatment. Thus, the wastewater will be more concentrated and will originate from the households only. The Sjöstad project includes the idea of a local treatment plant for the household wastewater. To evaluate this possibility, Sjöstadsverket, an experimental treatment plant was constructed.

Arbetet innehåller en allmän presentation om automatiserad testning, om var man kan tjäna tid samt vilka fällor som finns. Vidare har en analys gjorts på de olika verktyg som finns på marknaden idag och teknikerna bakom dessa. Därefter valdes ett verktyg ut åt FDT, nämligen Rational Visual Test. En kort presentation av detta program och de tekniker som stöds tas upp. Slutligen har ett förslag på en uppdaterad version av FDT?s testmetodik utformats för att anpassas mot en automatiserad testning..

The purpose of this study was to investigate the relationship between Health Locus of Control, Exercise habits, Food habits and Self-esteem (Personal self and Physical self) between two groups of student teachers at a university in the south of Sweden. Is health such as exercise, eating and self-esteem something that is controlled by internal or external factors? Student teachers that participated in Physical and Health programme and student teachers that participeted in other programme were investigeted. The participants (N = 160) answered the questionnaire. The Health Locus of Control scale and Tennessee Self-Concept Scale were used.

This essay describes and compares the extensive reindeer management to the more intensive, but grazing based, sheep management system in Sweden. Differences and similarities between the two production systems will be investigated by elucidating the economy, land use and possibilities to influence production and economy through breeding, feeding and product development. The reindeer management area covers the northern part of Sweden whilst the sheep management is dispersed over the country. Both reindeer and sheep are ruminants and have relatively high demands on the quality and digestibility of the feed however reindeers graze on mountain-and forest lands whilst sheep often graze inaccessible areas or cultivated grasslands. Selection intensity is generally lower in the reindeer management compared to the intensity in sheep breeding.

Organisationspsykologi kan ibland upplevas allt fo?r problemorienterad med stort fokus pa? just problem och konflikter i organisationer. Det finns dock en inriktning pa? de fo?rha?llanden och processer som bidrar till att ma?nniskor, grupper och organisationer kan frodas och fungera optimalt. Denna studie syftade da?rfo?r till att underso?ka eventuella samband mellan positiv feedback, self-efficacy, locus of control och socialt sto?d.

Syftet med studien är att göra en kartläggning över hur svenska skådespelares fysiska och psykiska hälsostatus ser ut hösten 2009. De områden som undersöks är depression, ångest, sömn, stress, arbetslöshet och hälsopåverkan, hörselproblem och tinnitus, samt alkohol- och droganvändning. En länk till en webbenkät med frågor från Hospital anxiety and depression scale, Perceived stress scale, Nationell undersökning om hörsel, yrsel och tinnitus samt Swedish longitudinal occupational survey of health 2006 skickades till medlemmar i Teaterförbundets skådespelaravdelning. 533 deltagare svarade på de inledande frågorna och 425 deltagare slutförde hela enkäten.Resultaten visar på förekomst av depression och ångest av klinisk betydelse, förekomst av sömnbesvär, samt förekomst av hög till mycket hög upplevd stress och prestationsbaserat självförtroende. Deltagarna upplever negativa konsekvenser av arbetslöshet.

The exclusion of visually impaired from the information flow presented to us through signs was what led me into this project. With a growing amount of information being presented to us on signs and digital information surface the need of communicating this information in a way that could be read by visually impaired is evident. Looking into different ways of communication, my goal was to create something that filled the need of the visually impaired without branding them as disabled. Having a close relative with bad eyesight is became evident on how much it limited her in her everyday life, not being able to navigate herself without the support of her husband. Through interviews with her and others with varying diagnoses I reached an insight in their situation. To my surprise they still favored a visual form of communication before an auditory or tactile form, because it?s easy to survey and quick to interpret.

For centuries, the human body has been used as a mean to project the norms, moral values and aesthetic preferences that exist throughout society. It has been controlled through constrictive fashion, family and social virtues and through how we perceive gender and sexuality. This essay strives to show, not only how the body and the aesthetic values coexist, but also how they work together and influence each other, with the body as the aesthetic medium. To do this, Michel Foucault?s writings of sexuality and his theories on morality and discipline, as well as Judith Butler?s works on normativity and performativity are being used.

Multi-branch companies are facing many challenges in order to become successful. Competitive advantages can be gained through a unified strong brand, standardised products and economies of scale. This normally calls for centralisation. On the contrary is decentralisation, which is said to improve work motivation and local market orientation, which are also competitive advantages. The focus of this thesis is to study how local branch managers want their companies to be structured in accordance with this dilemma.
