The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press.

Aim and question at issue: The aim of this study is to compare the motivation to participate in the course Idrott och hälsa A between students studying vocational and further education preparatory programs at upper secondary school.What level of motivation do the students of the two programs have towards participation in the course Idrott och hälsa A.What kind of motivational factors are important for students in the two programs concerning participation in the course Idrott och hälsa A According to the students of the two programs, what type of motivational factors would increase the motivation to participate in the course Idrott och hälsa A. Method: A quantitative study has been carried out using a questionnaire.

With access to internet, mobile payment can take over the role as the primary method of payment, as it can be used on any occasion. Questions are raised about which factors that are affecting the future users? attitude to use mobile payment, and if the service can be a threat to the traditional card payments.Method: This study is based on a quantitative method by the means of a survey design.

This paper is a literature study aiming to describe scientists newest theories andknowledge concerning the El Niño and Southern Oscillation. Firstly I have described the?normal? conditions with rising and sinking air in Hadley- and Walker-cells in theequatorial Pacific and from there moved on to explaining the reversed circulation patternsand higher sea surface temperatures (SST) leading to rising air and anomalousprecipitation in eastern Pacific constituting the El Niño phenomenon. My outermostinterest regarding El Niño has been the associated teleconnections, especially in nontropicalareas. I have described the El Niño effect on the Indian summer monsoon, ontropical cyclones and on storms and precipitation on higher latitudes.

Today the competition in the automobile industry is getting all tougher. The technology behind cars becomes more advanced. To get ahead of competitors car companies has to look into new areas of innovation.One important area is vehicle safety. Bigger companies have come so far in vehicle safety that difference between cars more depends on the car type (size) than the technology behind it.There is one area where vehicle safety that still has great opportunities for improvement, which is in active safety. The term active safety states that the car has the ability to identify treats and automatically respond to the treats.

Bakgrund Dåliga matvanor är en viktig bakomliggande orsak till sjukdomsbördan i Sverige och undersökningar har visat att arbetsplatsen är en bra plattform att förbättra matvanorna för att främja hälsan hos befolkningen. Syfte Syftet med studien är att undersöka hur matvanorna ser ut bland de anställda samt hur matsituationen är på olika arbetsplatser inom Västerbottens läns landsting. Metod En enkätstudie genomfördes vid Västerbottens läns landsting där 79 arbetsplatser tillfrågades att delta. Efter bortfall ingick totalt 207 deltagare från 18 olika arbetsplatser i studien. Data bearbetades och analyserades i SPSS 20.0 med chi-2 test och multiple response set, signifikansnivån sattes till p<0,05.

SYFTE Syftet med studien är att undersöka hur föreningen Stockholm Pride kommunicerade efter pridefestivalen 2011. Festivalen gjorde ekonomisk förlust och föreningen kunde inte betala alla sina räkningar. (Enligt årsbokslutet gick man back med 3,9 miljoner kronor.) Man kan tänka sig att en sådan situation hotar förtroendet för Stockholm Pride hos festivalens besökare, volontärer, sponsorer, artister, olika aktörer och intressenter. Frågan hur man försöker återvinna förtroendet blir intressant. Hur kommunicerar Stockholm Pride? Hur försöker Stockholm Pride återskapa förtroende?TEORI Att återskapa förtroende är centralt för en organisation i kris.

Maternal behaviour is crucial for the development of the rat pups? behaviour and stressresponses later in life. There are numerous studies evaluating the effects of the dams?behaviours on the pups, but not many addressing what can be made for wellbeing of the ratdams when breeding. Few studies have addressed the question of how the commonly usedrearing environment effects the dams? behaviour and in the long run how it effect the ratsreared to become our research models.

The fallout from the Chernobyl nuclear accident resulted in large deposits of caesium, iodineand strontium as well as noble gases in various parts of Sweden. 137Cs has a radioactive halflifeof about 30 years and is therefore one of few radio-fission products remaining inmeasurable quantities in the Swedish soil. Radiocaesium behaves similarly to potassium insoil-plant systems and is easily absorbed by plants. It is important to understand how 137Csbehaves in different ecosystems in order to minimize the risk toward humans.The aim of this study was to determine how potassium fertilization influences radiocaesiumcontent in different forest plants and fungi. Potassium fertilizer was spread once in 1992 withapproximately 200 kg KCl per ha.

Cumulative effects are seldom treated in Swedish Environmental Impact Assessments (EIA). This report treats these questions and which procedures and methods that can be used when assessing cumulative effects in EIA. This report is a literature study where also a case study is a part. The case study shows how existing methods for cumulative effects can be used in practice. The report is concentrated on biology and treats cumulative effects on premises of biodiversity and roads. Cumulative effects include both direct and indirect effects.

The purpose of this study is to investigate the lived experiences and treatment of Muslim women in their encounters with the social services. The primal themes for this study was: How does Muslim women experience the treatment of their case in the social services in a situation of need? How can the encounter and experience with the social services affect the clients trust in the social services?  What is the ideal treatment of women with a Muslim identity by the social services?The aim of this study was to investigate and capture the respondents lived perceptions and experiences with the social services, and thus the qualitative interview methodology was implemented to answer the research questions and hypotheses. Seven interviews with Muslim women were conducted in various districts of Stockholm, a city in northern Sweden. Five of the respondents were of ethnic Swedish origin and two were of other ethic origin.The results show that the majority of the respondents experienced a negative response at least once when in contact with the social services.

"Food security is a situation that exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life" (FAO Summit, 2003, pp. 28).Food insecurity is of concern regarding the Republic of Mauritius (ROM) since it is defined as a net food importing country. (Farming news, 2008). The impacts of climate change followed by their complexity could potentially have an increased risk effect upon the social and environmental welfare as well as the economic drivers in the ROM (www, UNESCO1, 2009). The primary victims when it comes to the impacts of climate change are the Mauritian agricultural producers since agriculture is highly dependent on climate stability, therefore affecting the yields of the producers.

Löslighet och transport av sällsynta jordartsmetaller i Källfallsfältets gruvsandsmagasinHugo de Campos PereiraSyftet med detta arbete har varit att kartlägga vilka mekanismer som styr lösligheten av sällsynta jordartsmetaller (eng. rare earth elements, REE) i sulfidhaltig anrikningssand vid den föredetta gruvan Källfallsfältet i Västmanland. För syftet har markvatten- och grundvattenprovtagning utförts, tillsammans med laktester och geokemisk modellering med Visual MINTEQ ver. 3.0.Resultaten visade att sulfidvittring är den främsta processen som styr pH i anrikningssanden, och därmed också indirekt REEs löslighet. Däremot är sulfidvittring ingen källa till REE i sig då ämnena inte föreligger sulfidbundna, något som oxiderat tillgänglighetstest NT ENVIR 006 visade.

The city of Uppsala and its surroundings are a very expansive area. A prerequisite for a sustainable development of the area is well-functioning supply of drinking water. In Uppsala municipality, the Uppsala esker and Vattholma esker are the groundwater storages for drinking water. Besides the eskers, other sources of qualitative groundwater in the Uppsala municipality are relatively poor and more than half of the area consists of ground conditions with a risk of saline groundwater. The neighbourhood of Vreta-Ytternäs is situated 10 km south of Uppsala, in the area with risk of saline groundwater but outside the municipal water supply.

One way of signalling commands to the horse during riding is through applying tension on the reins to create bit pressure in the horse?s mouth (Terada et al., 2006; Clayton et al., 2011). The skilfulness of the rider in using the hands when applying bit pressure has consequences both for the horse?s performance and welfare (Manfredi et al., 2010). At the trot there are large vertical deviations of the horse?s body which the rider must adjust and adapt to (Terada et al., 2006) and an unsteady hand due to inability to follow the horse?s movement can be a source of discomfort and conflict behaviour in the horse (Heleski et al., 2009).
