Det är tuffa tider, En kvalitativ studie om sexuellt riskbeteende bland ungdomar

Sexual risk-taking among teenagers has rapidly increased and only during the last decade the existence of Chlamydia has more than tripled. The future is facing big challenges to cope with the problem. Though the big efforts made on preventive work, Chlamydia continues to spread. The study aims to examine the existing attitudes towards sexual risk-taking among teenagers. The central mode of procedure is to use qualitative focus group interviews, and is complemented with a quantitative survey. A total of 30 teenagers, 15 boys and 15 girls, age 16-20, are participating from three different high schools in Gothenburg.

When and what determines the death of an animal? A study investigating the heart activity during slaughter of farm animals

Slaughter of animals should consist of two steps in order to be considered humane. The first step of the slaughter process is stunning, with the purpose of inducing unconsciousness and insensibility in the animal. The second step is exsanguination, which causes bleeding and eventually death. What death really means in these situations has been discussed intensively, but still no agreed definition has been accepted. Nonetheless, it is conceded that animals are declared dead when consciousness is irreversibly lost, and absence of respiration and blood circulation are observed.

Luftprovtagning samt analys av mono- och diisocyanater

When exposed to them, isocyanates can induce serious injuries in the respiratory tract and irritation on the skin and in the eyes. They are therefore interesting from the point of view of occupational health. The purpose of this thesis was to collect isocyanates in air with impinger-filter samplers and solvent free samplers. Furthermore the isocyanates were to be analyzed with liquid chromatography-mass spectrometry. The solvent free sampler consists of a polypropylene tube and filter holder fitted with glass fiber filters impregnated with derivatization reagent, coupled with a pump.

Tillvaratagande och återanvändning av träbyggnadsmaterial : tjänstedesign för återbruk inom byggsektorn

The purpose of this Bachelor degree project is to design different types of services that can increase the amount of re-used timber within the building sector and by that means improve their environmental efforts. By examining how the sectors environmental work concerning recycling and re-using timber as a building material is getting on at present, conclusions have been drawn about what further could be done for improvement.The project has shown that there is a scarcity of information and statistics within the sector, but that there are efforts in progress to change this. Questionnaires have been sent to a number of companies working with demolition and utilizing re-usable materials in order to find out what kind of problems there are within the trade. Unfortunately the survey gave insufficient result due to the low reply frequency.It is obvious that active environmental work within the building sector is important and the knowledge acquired while working with the project has led to the design of three suggestions for services regarded as being of interest for improving the negative environmental impact caused by the sector:Suggestion 1 ? Sale of construction parts prior to the demolition of a buildingSuggestion 2 ? Re-utilization circulation when manufacturing buildingsSuggestion 3 ? Education in relation to the purchase of houses  The positive and negative qualities of the suggestions have been examined with SWOT-analysis and further adaptions and the results have been interpreted.

Erkännande och verkställighet av utländska domar : Kommer det komma en tid för full implementering av principen om ömsesidigt förtroende?

The economical and judicial cooperation that EU constitutes results in that there is an increasing amount of international disputes arising. These international disputes in turn result in questions concerning private international law. The principle of mutual trust is not only an important principle in the entire judicial cooperation but especially important in the area of private international law. The principle means that the member states have to trust each other and the different legal systems. The aim of the principle is to ensure a well functioning internal market that is permeated by free circulation and freedom of establishment.

Effektiv lagerstyrning genom tillförlitlig prognostisering : Effective inventory control through reliable forecasting

This study was done regarding whether sealing or ventilation is the best solution to prevent moisture on cold attics. The authors of this report addressed the problem with moisture in attics when they started their cooperation with Peab.The methods included interviews with people, database research, and calculations of a project in Akersberga north of Stockholm. The conclusion is based on interviews and other information as they are analyzed in relation to the house of reference. The focus of this report is on problems with moisture in the attics known as cold attics.The background of the problem with moisture is that today?s slabs are usually insulated to save energy and that the attics nearly gives the climate as the outdoor climate.

Produktutveckling av koncept för isbanesystem

Today most ice rinks in Sweden use secondary refrigeration systems with a solution of calcium chloride and water as secondary refrigerant. Due to the large amount of energy such a system uses more efficient systems would be desired.An earlier study concluded in the possibilities of using carbon dioxide as secondary refrigerant with copper tubes as the loops in the ice rink. Since then 3 ice rink refrigeration systems has been built with carbon dioxide in copper tubes. Excluding the ones being direct involved in those projects there is still very little knowledge about how these system works. This study has been made primarily with the aim of adding to the knowledge concerning availability and cost and secondary to look at possibilities for improvement.A comparison between systems with carbon dioxide, calcium chloride respective ammonium solved in water has been made by using Decision Matrix.

Rousseau och Voltaire : Två helt (o)lika filosofers filosofier

This thesis has two purposes: (1) to analyze the emptiness in Blodbok by Christine Falkenland, and (2) to analyze my own reading of the same book. I have chosen to focus on how emptiness is expressed through the body, the language and the place in Blodbok, because of the deep impact these seem to have on the emptiness. The thesis discusses what kind of emptiness that is described, what it does to me as a reader, and how it is connected to other works by Falkenland. Cultural politics of emotions by Sara Ahmed, Uses of literature by Rita Felski and Pouvoirs de l?horreur by Julia Kristeva together form the theoretical framework.Blodbok is a poetry collection, about the loss of a mother.

Magnesiumintagets betydelse för blodtryck och magnesiumkoncentrationen i stickprov av urin, träck och blodplasma hos häst

The purpose of this trial was to evaluate the possibility to use sampling of faeces, urine and plasma, and measurements of blood pressure as methods of discovering hypomagnesemia in horses, as well as the application handiness of these methods. The most commonly used method of checking the magnesium status of a horse is to analyze samples of serum or plasma. The trial was of a switch-back design, in which the horses were used as their own controls. The animal material was five Swedish warm blooded trotters between six to ten years old, and weighing between 485-620 kg. The trial consisted of three periods that were two months each.

Kväve i Östra Mälaren : hur kunskap förvaltas och används i tillståndsprocesser

The nitrogen cycle in freshwater bodies is complex and consists of many separate processes affected by a number of important factors for example oxygen concentration in the water, temperature and circulation. Knowledge of the different components of the nitrogen cycle exists; however, a complete and comprehensive picture is difficult conceptually as well as theoretically. The available literature illustrates that the research on nitrogen and the related freshwater processes is still associated with high uncertainty of how much of the supplied nitrogen from the catchment is transported with the water versus and how much is lost due to denitrification, sedimentation or uptake by plants. This report is an interdisciplinary survey of Nitrogen discharge permitting. The research focuses in particular on the decision-making process, the levels of scientific standard and the administrative framework.Application for Nitrogen discharge permits are decided by the Environmental Court with council from their own experts as well as relevant government authorities and organisations.
