During the 20th century a significant proportion (about 15 %) of the peat-covered wetlands in Sweden were drained to improve forest productivity. Area wise, most of the forest drainage was done in northern Sweden, but relatively speaking a larger part of the wetlands have been drained in the southern parts of the country. Most often, the forest drainage resulted in increased forest growth, but failures were not unusual, and harmful effects, e.g. on species richness, have been a common cause for draining. Ditch cleaning is necessary for maintaining the ditches in good condition.

An interview study of horsemanship has been conducted in the community of Ängelholm. The study is part of a larger project, where a further four students who are writing their thesis? have conducted interviews in Lerum, Hässleholm, Nyköping and Enköping, a total of 52 horse holders in 5 different communities. The collective results are summarised in "Hur hålls hästarna i Sverige och vilka är motiven" by Catharina Svala. The purpose of this larger report has been to examine why Swedish horsemanship is the way it is today through communication with the various horse holders.

The interest for alternative forest regeneration methods increased significantly during the 1990´s after 50 years dominance of the clear-cutting system (Holgén & Hånell 2000). One reason for this was that clear-cutting was being more and more questioned by different envi-ronmental organizations and because the forest sector for economical reasons wanted to find cheaper ways to regenerate forests. In the beginning of the 1990´s two shelterwood experi-ments were established in a joint effort by Svenska Cellulosa Aktiebolaget (SCA) and the Dept of Silviculture, Swedish University of Agricultural Sciences (SLU). The experiments include various forms of cutting and shelterwood densities and represent productive spruce forests in central and north Sweden (Roggsjön in the province of Medelpad and Skikkis-jöberg in the province of Västerbotten, respectively ). The experiment next to Roggsjön has been reported earlier in three MSc theses, and is also the focus of this thesis.

In Sweden, there has been a continuous increase in the volume of housing construction for dairy cattle. Since 2004, the number of new, rebuilt and extended dairy cow houses undergoing preliminary inspection by the authorities has grown. The livestock farms have mostly focused on cow units instead of calf and heifer sheds; which has led to a need for information in this area. The purpose of the study was to improve advisors? knowledge about bovine building construction and function; to enable them to provide more qualified advice to conventional and organic milk producers who sustain larger herds.

Eventing is often called as the formula 1 in equestrian sports and comprises three disciplines: dressage, show jumping and cross-country. The sport provides excitement, challenge and joy and is the ultimate sport for intelligent riders and horses. Many are fascinated by the challenges the sport offers while other consider it foolhardy to ride a cross-country. Eventing is not a risk-free sport and has even been given the label of being one of the world´s most dangerous sports. What do those risks mean to the horse? And particularly, is it associated with good animal ethics to use the horse for eventing? Finding answers to these questions is not easy as it probably is not a clear and simple answer.

I Rosersberg har Trafikverket byggt en ny trafikplats under 2011-2013. Projektet stötte på komplikationer som ledde till att arbetet försenades främst på grund av förekomsten av arsenik i jord, berg samt grundvattnet. Dessa förseningar ledde till att projektet försenades med ca nio och en halv månad till en merkostnad på över 30 miljoner kronor till följd av över 200 (ÄTA).Detta projekt behandlar grundämnet arsenik i byggfasen och hur en hantering av ämnet bör gå till. Genom instudering av arbetsmaterial från projektet samt intervjuer med personer som varit inblandade har undersökningar gjorts och en sammanställning av dessa återfinns i rapporten. I rapporten har jag arbetat med att sammanfatta metoderna som Trafikverket arbetat med och hur projektet fortlöpt. Jag har även arbetat med att ta fram alternativa metoder för hantering och sanering av arsenik för grundvatten, jord- och bergmassor.Problemlösning som jag sökt svar på är:? Hur man stabiliserar arsenik och sedan hindrar det från att sprida sig från en nivå till en annan.? Hur man kan sanera och hantera arsenik när det förekommer i produktionsskedet, med en rimlig lösning.? Hur man återanvänder sanerade massorna.? Hur utförandet av sanering kan göras på kortare tid och med mindre kostnader.Dag- och grundvatten samlades i dammar som därefter pumpades ut till vägdiken för att därefter luftas genom självfall till Verkaån.

The Swedish Welfare Act § 4 says that "Animals must be kept and cared for in a good environment for animals and in such a way that promotes their health and allow them to behave naturally." Pigs in the wild spend 80% of their waking hours walking around and rooting for food, eating and exploring their environment with its snout. Fattening pigs in commercial farms spend 80% lying doing nothing. A lactating sow is lying down most of her day, and only 10-20% of the body surface is in contact with the floor, so the pressure is high on these spots. Piglets lie down and paddle with their legs, with high liquid content in the tissues, several times an hour, to stimulate and massage the sow's udder. In the existing system, these individuals are held more often on floors that are anything but inviting to sleep on.

Wound care of the horse?s distal part of the leg is challenging. Due to that distal limb wounds are easily enlarged, infected and generally heal slower than wounds on the body of the horse, the need for improved wound nursing arise. One way of improving wound nursing is to evaluate new ways of healing treatment. In this study, evaluation was made of a new product consisting of lactic acid bacteria and honey.

This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.

During thousands of years, reindeer have adapted to living under harsh conditions with large seasonal variations in climate and forage availability. This adaptation implies that body functions and nourishment needs are strongly bound to the season. In the summer the reindeer has to maximize food intake to build up fat and protein reserves for the winter. More than 200 different plant species are included in the reindeer diet, but since reindeer have an unique ability to use the nourishment in lichen, different lichen species make up a large portion of their winter diet in many areas. Fundamental for reindeer husbandry is access to natural grazing during most of the year.

Contemporary plant design can be examined by how it relates to two extremes - Nature and Art. This idea is explained by Noel Kingsbury in the book The Dynamic Landscape where he places designers and their projects on a gradient (Kingsbury, 2004). Nature, one of the extremes can be represented by a dynamic, species-rich plant design with native species and with nature as the ideal. The other extreme - Art implies a more static view on plant design. Here, the designs consist of colourful flowers, exotic species and cultivars with double flowers.

In this Master thesis an effective method is presented to find out what is requested in a forest or outdoor recreation. The aim with the study is to find out how Sveaskog can increase the general interest for experiences in nature and improve the access for recreation. Some questions that have been used to answer this purpose are: Who is visiting/not visiting the recreation area? How is it possible to increase the number of visits? The study is carried out in Kilsbergen and mainly centered around Ånnaboda, which is the natural place for people to meet at and undertake recreational activities. The method that is used is a mail-survey that was sent to visitors and people living in Örebro. People living in Örebro represent potential visitors who live close to the recreation area.

The fungus Gremmeniella abietina causes damage to conifers that can lead to tree death. In 1999 and 2001 the pathogen caused severe attacks in Sweden, where about 500 000 ha of pine forest were affected. Trees of all ages were attacked, but mainly forests between 30-60 years that were ready for their first commercial thinning. After recommendations from the forest agency, sanitary fellings were made to trees that had more needle loss than 85%, a total of about 50 000 ha. Economic losses have been estimated to more than one billion SEK.

The aim of this master thesis is to investigate how the OPACs Online Public Access Catalogue used by public libraries have adapted the features and possibilities offered by online catalogues, for the purpose of searching for fiction. This is done by comparing five OPACs to Amazon.com, an online bookstore. The questions investigated are: Have the OPACs developed from the principles of the card catalogue and adapted to the features and possibilities offered by online catalogues, when searching for fiction? Can the library catalogue provide the same features as Amazon.com, when searching for fiction? How do the OPACs use the resources that online catalogues provide when searching for fiction, compared with Amazon.com? The thesis is based on two qualitative studies. The first study presents five OPACs from different library systems and examines which features they have in common with Amazon.com.
