The idea behind this project came from a feed study executed two years during the lambing season. Both years wool loss was experienced. Low temperature in combination with shearing was believed to cause the wool loss the first year, while protein deficiency was believed to be the cause the second year. In the literature many causes of wool loss are described; mechanical wear, telogen effluvium, bacterial dermatitis, external parasites, wool break, scrapie, genetic causes and nutritional deficiencies are some examples. The aim of this thesis was to study causes for wool loss and how common wool loss is in Swedish sheep herds.

The goal of this paper is to find out how solar cells can improve energy efficiency on-board M/S Sydfart. The paper is based on a number of energy measurements on board the M/S Sydfart. The solar surface is calculated by measuring the available space for installing solar panels. Global radiation data is taken from STRÅNG's database, the data is then used to calculate the theoretical power produced by the solar cells. Energy efficiency is analysed in two ways.

Today, the tourism sector is the fastest growing industry in the world and also includes one of the foremost for instance in the number of work and added tax. The sector entails a lot of positive factors but also negative consequences, such as overexploitation and wear on natural areas. However, even the visitor industry contributes to smaller localities boost by creating new jobs where depopulation occurs. This study focuses on the town Kisa in Kinda Municipality. The purpose of the study is to highlight the importance of tourism for migration to a town and to show the importance of developing sustainable destinations.In the results of this study it emerges that more job opportunities are requested by respondents for increasing Kisas attractiveness.

I detta arbete studeras hur vinterklimatet i Sverige kommer att skilja sig åt mellan perioderna 2071-2100 och 1971-2000, med avseende på parametrarna temperatur, nederbörd, vind, snödjup och snöutbredning. Klimatmodelldata (CORDEX) i upplösningen 12.5 km baserade på tre olika strålningsdrivningsscenarier (RCP-scenarier) behandlades i Matlab och modellerades över Sverige. För att analysera upplösningens betydelse tillhandahölls även data i upplösningen 50 km för en tioårsperiod. Scenariot RCP 8.5 kan ge så mycket som 10 grader varmare vintrar, med uppemot 50% mer nederbörd. För RCP 2.6 förändras nederbörden med -5 till 20%, och temperaturen ökar med 1-4 grader.

Abstract In order to make the modern agriculture less dependent on non-renewable external inputs, it has to rely more on ecosystem services. The agricultural system produce not only food, fiber and fuel, it also generates other ecosystem services such as e.g. photosynthesis, recycling of nutrients, influencing local microclimate, pollination, biological control and detoxification of noxious chemicals. This study is an attempt to get a better understanding about the interaction among different ecosystem services and different habitats capacity to generate them. An evaluation of eight different methods is done. The ecosystem services studied are the ability to absorb solar energy, biomass production, botanical diversity, decomposition and natural predation of aphids.

Hemp is an old agricultural plant and has been used for hundreds of years for making textiles, ropes and other fibre products. In the middle of the last century the Swedish government prohibited all growing of hemp. Natural fibres were replaced by syntetic fibres instead. Today there is a newly awakened interest for using natural fibres from renewable materials. Growing of industrial hemp for fiber is allowed in Sweden again. I want in my Paper give Swedish growers an insight of which harvesting methods that have been tried in Sweden and how they worked.

Det här är en studie kring ämnet flexibel utformning av offentliga rum, och ett förslag på hur Båstads hamnområde skulle kunna utvecklas till en plats som på ett mer tillfredsställande sätt kan användas året runt. Idag är hamnen en plats som präglas av några månader med intensivt liv och mycket rörelse under sommaren, för att sedan bli en tom och oanvänd plats vintertid. Förslaget har föregåtts av analyser, både under vinter och sommar, av hamnens rumslighet, aktivitet, rörelse och attraktioner, en litteraturstudie kring ämnet flexibel utformning av offentliga rum, samt två studiebesök på mindre orter i Sverige som kämpar med en liknande problematik. Förslaget har också föregåtts av en inventering av området, samtal med tjänstemän på Båstads kommun och näringsidkare i hamnen samt studier av tidigare planprogram och planer för hamnen framtaget av kommunen. Med utgångspunkt i resultaten av analyserna och med inspiration från litteraturstudien och studiebesöken har jag tagit fram ett förslag på hur Båstads hamnområde skulle kunna utvecklas, göras mer flexibelt och därav mer användbart hela året.

By using pollen analysis, 14C-dating and historical sources, I studied the history of vegetation and land use at an abandoned forest settlement near the Lade summer farms in the parish of Mora, Dalama. The aim of this paper is to investigate the agricultural establishment and development, the effects of this on forest vegetation, and the origin and development of summer farming. The analysis of pollen in a peat core revealed that a settlement was established at Lade around 1000 AD. Cereal cultivation, hay-making on the mire and extensive forest grazing were intro-duced as a complete agricultural system. Pollen analysis and the presence of ancient fields suggests that cultivation took place on permanent fields. Barley was the main crop, but rye and hops/hemp were also grown at the settlement.

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.
