EN MILJ?STUDIE OM DE GEOKEMISKA F?RH?LLANDENA I SK?RHAMN, SVENSKA V?STKUSTEN
The following study aims to investigate the environmental conditions of the harbor of Sk?rhamn, a small fishing community on the west coast of Sweden. The interest to do so rose as a newly built apartment residence failed to connect the sewage pipes of 18 apartments, causing the untreated sewage running into the sea. The parameters accounted for are the C/N ratio, total organic carbon (TOC) as well as total nitrogen present (TN) and ?13C in the top ten centimeters of a sediment core retrieved in the Sk?rhamn harbour.
Energianalys av hygieniseringssystem : jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala
The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand. The method implies that the substrate is sanitized during ten hours in the digestion chamber, where the temperature is 52°C.
En studie av etiken bakom australiensisk missbrukarvård enligt harm reductionmetoder
Syfte: Syftet med vår uppsats är att belysa den etiska dimensionen av harm reductionanknuten missbrukarvård. Till vår hjälp har vi haft etiska teorier och sociologen Zygmunt Baumans begrepp. Frågeställningar: Vi har använt oss av två huvudfrågor som vi därunder bryter ner i konkreta frågor. 1 Hur ser de etiska resonemangen ut hos personal verksam inom harm reductionanknuten missbrukarvård?Vilken typ av etik använder de sig av? Har de centrala etiska principer, vilka? Hur ser de på etik och moral? Följer de etiskt formulerade regler? Hur ser de på prohibition? Hur ser de på drogbruk? Hur ser de på människan? Vad driver dem i deras arbete? Hur ser de på harm reductions påverkan på samhället?2 Hur kan man förstå harm reductionmetoders framväxt ur Baumans sociologiska perspektiv?Hur kan harm reductionmetoder kopplas till det senmoderna samhället? Hur kan harm reduction rättfärdigas etiskt utifrån ett sociologiskt perspektiv? Hur kan harm reductions förklarar sociologiskt? Vilka förutsättningar fanns för att harm reduction skulle kunna utvecklas? Hur kan Baumans begrepp förklara harm reductions ställning i det senmoderna samhället? Metod: Vi har använt oss av en kvalitativ metod med intervjuer som redskap.
Organiskt / syntetiskt i dagens musikskapande
Title: Organic / Synthetic in today's creative music making. This work intends to find out what synthetically versus organically produced music means for a songwriter / producer as well as for an artist in their everyday role of occupation. What are the positions regarding these two methods and how do they relate to these concepts? This study also concerns the general view of music produced with each one of these methods and to which extent there exists prejudice towards them. The method used for data collection is qualitative interviews.
Alternativa drivmedel : Vilket alternativt drivmedel uppfyller bäst Försvarsmaktens behov?
This essay is written within my education for Technical Officer in the Swedish armed forces. The essay describes the alternative fuels that the Swedish armed forces can make use of if the supply of fossil fuels is insecure. The alternative fuels that are described and compared are; Synthetic diesel, Organic diesel, Methanol and Ethanol. The essay describes the process of producing the alternatives, the need for modification and the economics for each alternative. The alternatives are compared and assessed for their ability to secure the supply of fuel to the Swedish Armed Forces.
Helicobacter spp. i digestionskanalen hos svenska katter : en metodologisk och klinisk studie
Following the accident at the nuclear power plant in Chernobyl in 1986, great volumes of137Cs were distributed over large parts of the former Soviet Union and Europe. Over Scotland,radiocaesium was deposited as wet deposition. Due to the relatively long physical half-life of30 years, there are still measurable activity concentrations in the natural environment. Thisstudy was made on two organic soils, Knockandy Hill and Rora Moss, situated in the easternpart of the central highlands of Scotland. At these two sites, studies on migration and transferbetween soil and plants were conducted.

Hästköttskandalens konsumtionspåverkan : Konsumtion kopplat till miljörelaterade märkningar
The discovered horse meat scandal has had great impact in the media and given many question marks as to how consumers should be facing meat labels. In the survey made lead consumers to ask themselves, whether they think about their consumption of reliable markings discovered at a risk and, if they have changed their consumption habits since discovered horse meat scandal. The survey was carried out in a grocery store in Karlstad city central, where the results show consistent numbers. People do not like change, and in this case, do not like to change their consumption patterns. The same patterns of consumption before and after the horse meat scandal reflects the results but with only three respondents exception.
Downward migration and transfer to plants of radiocaesium in Scottish soil profiles : a comparison with earlier studies

EN ÖKANDE BOLÅNEMARGINAL - En redogörelse för penningpolitikens inverkan på bostadsmarknaden - Nationalekonomi
The general consensus is that the gap between the Swedish variable mortgage rate and the repo rate has increased over the last years. Although the Riksbank in recent times has cut its base rate, many banks have chosen either to leave the interest rate on variable mortgages unchanged, or they did reduce it but by less points than the reduction in the repo rate. The linear relationship between the repo rate and the variable mortgage rate has changed over the last decade and the mortgage margins these days are relatively high. This can somewhat be explained by the new rules introduced in the bank sector requiring banks to increase liquidity and equity. Since mortgage loans play an important role in banks? lending business it is of interest to gain knowledge in whether a repo rate reduction latterly has generated a limited affect on the banks lending rates..
Ekologisk och småskalig uppfödning av slaktkyckling och kalkon i Sverige :
In Sweden in January 2005, there is only one producer of organic broilers and
none of organic turkeys. But there are, on the other hand, a few small-scale
producers whose housing systems to some extent are similar to what is stipulated
in the organic standards. The aims of this work are to investigate what housing
systems are used by the Swedish small-scale producers of broilers and turkeys,
what main challenges they are confronted with and if there is an interest and a
possibility for a change-over to organic production.
For the first part of this work a literature study was performed with the
purpose of detecting the main health problems in conventional as well as smallscale
production. A special focus was on coccidiosis and leg weakness as those
were considered to be of particular importance.
A study was made of Swedish small-scale poultry production units. In two
groups of broilers from the same producer and in three flocks of turkeys the level
of Eimeria oocysts in faeces and litter was investigated.
Värdering av kvävet i organiska gödselmedel :
Within agriculture it is important to optimize the use of nitrogen, not only from an economic point of view but also to minimize damage to the environment. This can sometimes be difficult, especially within organic farming. Organic farmers are using increasing amounts of waste products from the food industry to cover their nitrogen needs. These different organic fertilizers release nitrogen at different rates and under specific soil conditions. Because of this, it would be beneficial to have a standardized method to measure the amount and rate of nitrogen mineralization from organic fertilizers.
This project contributes to this knowledge by investigating whether relatively simple and
repeatable laboratory methods can be used to estimate the nitrogen fertilizer value of organic fertilizers.
Fordonsgas från deponier : en potentialstudie i Biogas Öst-regionen
The demand for biogas as vehicle fuel has risen sharply and there is a great need for increased production. A possible addition of vehicle gas can be produced by upgrading landfill gas which is formed by degradation of organic waste. This thesis investigates the potential of producing vehicle fuel from landfill gas in the region of Biogas Öst.In 2008, an amount of 32 million Nm3 landfill gas was extracted in the region. This level can be maintained for another ten years if the efficiency of gas extraction is improved. The annual production will decrease with time since landfills aren?t allowed to receive more organic waste.
Rötning av matavfall ? en studie av metanutbytet hos matavfall förbehandlat med skruvkrossteknik samt vid samrötning med bioslam från pappersbruk
Today's society is facing major challenges. In order to reduce the climate impact fossil fuels should be replaced with fuels that do not contribute to the greenhouse effect. The growing population generates organic waste originating from industry and households so called organic fraction of municipal solid waste (OFMSW). Through anaerobic digestion, waste can be utilized to produce energy-rich methane gas. In this way, waste can be a resource instead of a burden on society.
Optimerad höstveteetablering : en litteratursammanställning om såtid, radavstånd och utsädesmängd
This bachelor thesis is intended to gather the knowledge and experimental data on the winter wheat crop production relevant for Swedish conditions, with focus on sowing time, row spacing and seed rate. This essay is a literature study with a minor component based on interviews with farmers producing winter wheat. The work is divided into a background part where basic knowledge of winter wheat physiology, development and environment interactions are described and one part where results of field trials studies are presented.
Optimal date of sowing winter wheat depends on annual weather variations. Because it is difficult to forecast the weather the choice of sowing date should be based on weather statistics, production experience and previous results depending on sowing date.
