Cannabis är den vanligaste illegala drogen bland unga vuxna i Sverige. Det är en omdebatterad drog, debatterna handlar ofta om huruvida cannabis effekter är negativa eller inte. Detta examensarbete undersöker om det finns skillnader i problemnivå inom olika livsområden beroende på grad av cannabisbruk. Examensarbetet är en kvantitativstudie som genom ett antal statistiska analyser jämför tre grupper av unga vuxna samt predicerar sannolikheten för vilka som löper störst risk att vara regelbundna cannabisanvändare. Resultatet tyder på att problemnivån ökar inom flera livsområden beroende på grad av cannabisbruk.

The purpose of this thesis is to investigate how the metadata format Dublin Core is applied within five Swedish search engines. The objects of the investigation are Rättskällan, studera.nu, Svenska miljönätet, Svesök and the web catalogue of Uppsala University. Dublin Core is a flexible and adjustable format, which can be used in many different ways and in various projects depending on the target groups and objectives of the activity. We compare the differences and similarities between the five search engines concerning their usage of metadata in general and Dublin Core in particular. The material of the investigation consists of metadata records, which are collected by a robot and examined manually.

Åmotfors Bruk AB (ÅBAB) has today an inefficient production of steam for the manufacturing of paper. Unpredictable energy prices and modernisation of the current equipment has been the underlying factors to invest in a thermal power plant, mainly driven by garbage. This facility will not only use the steam for paper production, it will also generate electricity through a steam turbine. Today, when a fault on the supplying line occurs which leads to disconnection of the external grid, all the support of electricity to Åmotfors Bruk (ÅB) will disappear. This will lead to major interruptions in the paper production, which will cause severe economical losses.

 To enjoy work, and be satisfied in the work you do, is important to most people. Work scientific research shows that dissatisfaction with physical or the psychosocial work environment often gives negative effects on the performed work. The purpose of our study is to chart the experience in work satisfaction and psychosocial work environment amongst nurses within psychiatric care. It is an empiric cross section study. The participants in the study contains nurses who are either employed on a conditional tenure or have a temporary post (>3 months) in policlinics and wards in general adult psychiatric care (n=126).

By using industrialized building, pre-installed modules can be delivered to the construction site where they are easily mounted. This method has many advantages compared to on-site manufacturing, for example, the precision during the production process should be much higher than building each wall and floor on site. Furthermore, the quick erection procedure when using prefabricated elements and the possibility to use weather protection has the advantage of not being dependent on weather conditions, and many other factors.Masonite Beams AB is a Swedish company (a member of the Norwegian company, Byggma ASA) with a relatively new technology using light weight beams as bearing elements in the walls and a certain stiff board lamella slap which is mounted on the top of the floor structure creating an integrated stiff beam / board floor structure. The elements are flat which make it much easier to transport the elements from the factory to the building site where the building parts are easily mounted with special mounting stud.One of the main drawbacks of lightweight structure is the sound transmission. The main topic is low frequency annoyance, however the complex structural elements and their mutual sensitive connections other acoustical problems might appear.

Healthy calves are the foundation in order to run a profitable diary production. Being healthy as calf results in a better start in life and good growth is expected to follow. Within dairy production it becomes more common to rear calves in groups and feed them by an automatic milk feeder. The milk feeder enables for the calves in greater extent to ingest milk or milk replacer several times per day and they are also able to perform natural behaviors in greater extent. Group rearing of calves puts higher demands on the animal keepers to localize individual calves in the group pen, showing signs of illness.

This study examines how social workers in child and youth units within Social Services perceive and experience working with violence in young people's intimate relationships. The study aims to highlight whether there is a need for a domestic violence team within the child and youth units. Violence in young people?s close relationships is a growing societal issue, with limited establishment within the research field. While research on the frequency of such violence has increased, studies focusing on tailored support measures have lagged behind.

A totally mixed ration (TMR) is a mixture of all the necessary feed components for the cow. She will eat the exact same feed in every bite which will make the rumen pH more stable and always supply her with a constant proportion between roughage and concentrate. This will make it possible for the cow to eat more dry matter (DM) a day because the fibre requirements are fulfilled. If a part of the concentrate is given separated from the mixture it is called partly mixed rations (PMR) and is almost always used when using an automatic milking system (AMS). When using TMR and PMR it is important to have a high hygiene, be accurate when mixing the feed and to look after cows in a good and strict way. The aim of this study was to document different farms with PMR in an AMS to see which routines they have and how they are managing their production.

Today there are no analgesic drugs approved to be used in goats. Drugs approved for use in other species are consequently being used without knowing the pharmacokinetics of these drugs in goats. The purpose of this study was to investigate the pharmacokinetics of the opioid butorphanol when given subcutaneously in goats. Subcutaneous administration might extend the half-life compared to intravenous or intramuscular administration. Eight clinically healthy, non-pregnant 6 months old female goats were used.

Earlier studies have shown that musculoskeletal disorders among animal keepers are more frequent than in other occupations. Most of the farms have expanded and the farmers who used to work alone have suddenly become a work manager with several employers. There are only a few studies made on the work environment in dairy farms. Our study is based on a questionnaire and is a part of a project called large dairy herds. The study is based on data from the persons who milk most of the time. The questions they had to answer were about the work environment, musculoskeletal disorders and the psychosocial environment. The results of the survey are presented in diagrams and figures. It was common that the dairy producer themselves answered the questionnaire.

Syftet med föreliggande studie var att undersöka vilka ordtyper som är lätta respektive svåraatt nå fram till med bliss standardkarta och vilka strategier som är mer respektive mindreeffektiva. Deltagarna, 24 kvinnliga studenter utan funktionshinder, delades upp i par. Den enai paret fick i uppgift att förklara 12 målord, som inte finns med på bliss standardkarta, enbartgenom att använda bliss standardkarta. Den andra i paret fick i uppgift att gissa vilkamålorden var. Eftersom tidigare studier indikerat att ordklass, frekvensnivå ochabstraktionsnivå kan påverka ords svårighetsgrad, valdes målorden i föreliggande studieutifrån dessa variabler.

In developing countries such as Vietnam the population consumes more animal products for example milk and meat than before which requires greater livestock production. Ruminants contributes to more methane emission which creates a dilemma between food production and its environmental impact. By feeding ruminants with nutritive crops which humans can not assimilate the animal performance will increase in terms of better growth and milk production without inpinging on food that can be consumed directly by humans. Increasing animal performance reduces methane emission in terms of amount of methane in kg-1 milk and meat which today is much greater in developing countries than developed countries. The aim of the study was to investigate tropical tannin-rich legumes for their potential as a feed supplement for ruminants made in vitro.

To establish good horse welfare there are several factors that need to be considered. One important factor is the environment in which the horses are kept. In Sweden horses are stabled during long periods of time in the cold season and consequently the stable environment is even more important. The most essential environmental factors in a horse stable are ambient temperature, relative humidity (RH) and concentrations of contaminants in the stable air. The air in a horse stable contains dust, noxious gases, moulds and microorganisms which all can contribute to developing respiratory diseases in horses.

It is imperative to provide more information regarding changed conditions resulting landslide events in a future climate. The aim of this thesis is to assess landslide susceptibility in Huddinge Municipality in middle Sweden. The main purpose is to produce a map, to visualize landslide susceptible areas, and to integrate the result with changes in physical factors such as climate change. Also, the thesis aims to analyze anthropogenic factors such as changes in land use and an increasing population in Huddinge Municipality. Methods used are GIS-analyses, interviews with staff of Huddinge Municipality, and field observations.
