In order to avoid harmful substances ending up at the municipal sewage treatment plants, it is important to purify the wastewater at the source. One such source is the wheel washers available in many tire garages which are used to wash the wheels on our vehicles when we change between summer and winter tires. It is important to wash the wheels before storage, to extend the tires lifetime. The purpose of this study is to find a green innovative solution for reduction of emissions of heavy metals at the source, so that the sludge from the sewage treatment plants can be used as fertilizer. The target is to find a wheel wash method which leads to compliance with the guidelines for car washers, and that also provides a better washing result than with the existing method.

The purpose with this study was to describe and analyse the daily activities of a criminal group in a southern suburb of Stockholm, Norra Botkyrka, and their attitude to drugs, the police, crimes in general, accomplices and their plans for the future. The study is a combination of different qualitative methods that is built on unobtrusive methods and interviews that was carried out during winter in 2006 and spring in 2007 and six interviews. My interest to carry out this study was grounded on my several years of experience as a prison and probation officer in the prison. I chose to ?live? with a group of criminals and participated in some of their social activities.The respondents that I chose to call ?anti-heroes? proudly tell me about their criminal lifestyle that characterizes of violence, drugs, crimes and conflict where this people show no regret.

Camelids, especially alpacas, have increased in popularity during the last decade, with the result that they are more frequently encountered by field practicing veterinarians and pathologists. Knowledge regarding their health care and their diseases under Swedish conditions is, however, limited. This became clear in a postal survey among Swedish alpaca owners conducted in 2008. To improve knowledge about camelids in Sweden, this study has examined 107 necropsies, including 93 alpacas and 14 camels, conducted at the National Veterinary Institute (SVA) in Uppsala and at Eurofins in Kristianstad and Skara during the period 2001-2013. The study has shown that camelids in Sweden suffer from diseases similar to those previously reported in other countries in Europe and North America.

Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.

Sustainable destination development has in recent years become an increasingly important concept for tourism destinations. A destination must take into account the environment if it wants to continue being a successful tourism destination in the future. This essay investigates what needs to be developed on theislandofSandhamnfor that the destination can be more attractive in the off season and how the players on Sandhamn integrate to develop Sandhamn in a sustainable manner. One market research and interviews with five different players were made. Through these interviews grew an understanding for how the cooperation between the municipal and the private party looks like and how the history of Sandhamn is the foundation for the islands tourism development.

There are two species of voles that cause damage in Swedish fruit production: the water vole (Arvicola terrestris) and the field vole (Microtus agrestis). Both species make the most damage during the winter season. The water vole makes subterranean burrows and cause serious damage by gnawing on the tree roots. The field vole seldom makes burrows and gnaws the bark at the base of the tree trunk. In recent years there have been several reports about increasing vole damage.

Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between regions. In this study, I investigated if landscape structure (e.g. agricultural dominated landscape opposed to forest dominated landscape), forage availability, population density and disturbance (e.g. roads and settlements) affect bark-stripping frequency.

The aim of this study was to evaluate the stir drying method, for drying of grain during Swedish conditions. The evaluation was done during the harvest year 2004, on four farms with stir driers. The driers were evaluated for their energy consumption, design, stirring effectiveness and how much time the farmer has to spend on every tonne of grain. A comparison was also done with conventional Swedish high temperature driers. Totaly six batches of grain from stir driers were examined, mostly winter wheat, but also barley and wheat.

Resin-top disease is a rust fungi that occurs both as a host alternating form, Cronartium flaccidum G. Winter., and as a non-host alternating form, Peridermium pini Pers. The host alternating form can use a variety of hosts but the most commonly used species in the boreal forest is Melampyrum sylvaticum. In Scandinavia the Resin-top disease infect Scots pine, Pinus sylvestris L. The fungus infects the needles through the stomata and then grows through the branch to the stem where it strangulates the vessels transporting water and nutrition to the treetop, which kills the top.

Eutrophication was recognized in the early 1900's and results in severe algal blooms, increased biomass production and eventually leads to an altered ecosystem. In Mälardalen we find the most eutrophic lakes. Most of the applied phosphorus and nitrogen into seas and oceans comes from agriculture, and the nutrients losses are affected by local weather conditions and soil type. Guidelines for storage and distribution of manure were introduced in the 80s, and the rules were strengthened January 1, 2010. Localities and previous county administrations can whether there are special reasons, grant an exemption for manure application during winter-periods despite the current ban.In this essay I have examined how many exemptions of manure application that has been granted at the Sagån river, and what implications it has for the eutrophication of Lake Mälaren.

Detta examensarbete behandlar växter som trivs vid havet. Arbetet baseras på frågan vilka växter som tål ett vindpinat och utsatt läge? Arbetet beskriver vad man skall tänka på när man börjar planera en trädgård vid havet. I arbetet har jag tagit upp vilka träd och perenner som man kan använda sig av när man skall skapa en trädgård vid havet. Syftet med arbetet är att man skall kunna använda sig av mitt arbete när man åker till plantskolan för att inhandla växter.

The aim of this study is to examine how work at music departments in public libraries has changed with time. To analyze this, the role of music libraries as well as music library users, selection, holdings, acquisition and technological development have been examined. The examined data consists of qualitative interviews with music librarians and library assistants at public libraries in Sweden. To get a time perspective, handbooks and articles about music departments in libraries have also been analyzed.This study emanates from Sanna Talja?s discourse analysis of music libraries in Finland.

A common perception is that fungicide treatments increases yield, but that the nitrogen of the particular grain is diluted so that the overall removal of grain nitrogen from the field remains unchanged. The aim of this paper is to demonstrate that a healthy crop reduces the risk of nutrient loss from agricultural land. The results from genotype and plant protection trials often show constant nitrogen content in the grain, although the yield has been increased. Results from such experiments are therefore processed in order to confirm this and show that it is no statistically significant difference between the protein content (and also nitrogen content) in crops which have undergone fungicide treatment compared to crops which remained untreated. The trials processed have been carried out in the southernmost part of Sweden and are distinguished to concern winter wheat production.The explanation to the results is that a healthy crop is able to maintain the biological functions of the plant in a more efficient way than a crop damaged by a fungal infection.

The southern part of Sweden, Skåne, is frequently exposed to storms causing great damage to Norway spruce (Picea abies L. Karst.) stands. A storm during the winter 1999/2000 raised the attention of the problem. A lot of forest owners got large areas of spruce stands wind thrown during this storm. Can naturally regenerated birch (Betula sp.) be an alternative on these wind-exposed sites? This was the main question I was facing when discussilig the problems with Esben Möller Madsen, Söderåsens forest district. The aim of this master thesis was to present an economic analysis of Norway spruce versus birch.

Since the wild boars (Sus scrofa) escaped from their enclosures in the 1970s, their numbers has increased dramatically. It is an animal that is currently involved in many traffic accidents. The wild boar is a popular animal to hunt. As the population has grown so has the hunting. But, unfortunately, there have also been an increased numbers of attacks on hunters.
