This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

The purpose of this paper is to study how the wooded hay meadow of the forest district of northeastern Scania is preserved today, and what local history it has, to thereby achieve a better understanding of the dynamics of the landscape and the complex of problems involved in keeping a historical element of the cultural landscape alive. To accomplish this, literature concerning the subject has been studied, experts have been consulted and an example, the old farm Sporrakulla in Östra Göinge municipality, has been studied. The paper states that the wooded hay meadow constitutes an important part of the history of northeastern Scania, where it provided leaf fodder and hay for the farmers keeping cattle. Today, however, only a few wooded hay meadows remain. One of these is the studied example at Sporrakulla, where juridical Protection like Natura 2000 and financial support of maintenance like miljöersättningar make sure that the wooded hay meadow will remain.

The artic fox is under threat of extermination in Europe. The population decreased strongly at the beginning of the twentieth century because of intensive hunting. The artic fox was placed under Protection by law 1928 in Sweden but despite this the population has had difficultly to recover. This can depend on several reasons, but the main threats are shortage of food and competition from the red fox. Along with Norway and Finland, Sweden has carried out a project called SEFALO (Saving the Endangered Fennoscandian Alopex lagopus), whose objectives were to prevent continued decreased populationnumbers and through, for example supplementary feeding, help the population to recover.

Diversity of ground beetles (Col: Carabidae) in managed riparian grasslands. The carabid community in moist seminatural grasslands was studied at three different sites in mid-Sweden. Pitfall trapping was carried out during six weeks in spring and early summer 2003. Eight transects, each containing seven pitfall traps, were placed in three different management regimes, either late or continous grazing, or meadow. The species composition was analysed by ordination analyses, i.e. DCA and CCA.

Major changes within the agricultural politics today have forced the dairy production to scaleup, in order to compete on a global market. This has resulted in a reduction in the number ofsmaller dairy farms in Sweden, from about 40000 to just over 4000 over the last 30 years. Thepurpose of this study Svenska mjölkbönder, snart ett minne blott? ? Markbygdensmjölkbönder i tankar om mjölkproduktionens nuvarande situation och framtidsutsikter, is topresent the opinions of dairy farmers in Sweden, regarding the Swedish dairy industry and therelation to their own dairy production. A secondary purpose is to problematize how theconsequences of pastures and cultural landscapes influences human society as dairy farms andgrazing animals are becoming fewer.

This essay concerns equality statistics as part of a population census. It is a kind ofstatistics that is not in action in Sweden because of data Protection law for sensitivedata (Personuppgiftslagen). This kind of an enlarged census is requested frominternational institutions like the UN and the EU as a tool to combat discriminationand to keep track of human rights. In Sweden there is a prohibition against collectingsensitive data regarding for instance sexuality, disability, transgender, ethnicbackground and national minority.The essay examines arguments from minority groups in Sweden, who participated inan enquiry done by the Equality Ombudsman on a government assignment 2011. Theenquiry process was done during 2012 and resulted in the report Statistikens roll iarbetet mot diskriminering (The Role of Statistics in Combating Discrimination).The starting point of the essay is to look at equality statistics with a two foldedpotential: as liberating or oppressive for the counted.

This essay addresses and treats the employer's obligation to work adaptation for people with a physical disability according to discrimination law and the work environment law. Furthermore it also treats the employer's obligation to rehabilitation of employees that has a reduced working ability as consequence of their work. The essay also intends to investigate if there are any differences in the employer?s obligation to work adaptation when recruiting and the employer?s obligation to work adaption for an existing employment. In this work, there is a background chapter which describes the UN and the European Union's approach to work reduction ability and disability. Furthermore, there is a detailed description of the work environment law, the discrimination law, the social insurance code and the employment Protection legislation.

Ensåsengruvan is a mine situated within Ljusdals municipality in central Sweden. Themine was in use from 1984 to 1991 and has since been undergoing a remediation program. Mine tailings from sulfide rich ore is a potential environmental hazard due to its tendency to cause acid waters and heavy metal leakage. Lake Ensjön is situated one kilometer from the mine area. Due to the hydrological conditions it was not expected to receive inflowing water from the mining area.

Today the individual ventilated cage system (IVC-system) is the most commonly used system when housing rodents. IVC systems are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a Protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare for two different strains of laboratory mice (NMRI nude mice and C57BL/6NCrl mice) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. 108 mouse pups from each strain (in total 216 mice) were selected after weaning at an age of three weeks and tested during 5 weeks.

Starting point to this Paper is the idea and wish to adapt the society and its different activities to a recycle society. A building area in Göteborg is planned and investigated for such adaptation. In the district named Skogaberg, about 130 households totally are planned from what 20 are blocks of flats. The idea with this project is to constitute an alternative sewage system, a Blackwater system, were the fractions of most nutrients and least pollution are separated, taken care of and utilised. The aim is to get a market and use the nutrients of the organic waste from the household in agriculture use.

Bakgrund: En försäkringstagare kan välja att antingen köpa en försäkring genom direkt kontakt med ett försäkringsföretag eller genom att anlita en försäkringsförmedlare som sköter upphandlingen av de försäkringar som försäkringstagaren önskar. Under det senaste decenniet har försäkringsförmedlarna kommit att utgöra en viktig del av försäkringsmarknaden och de omsätter stora ekonomiska värden i sin verksamhet. Mot denna bakgrund är det av stor betydelse att den lagstiftning som reglerar förmedlarnas verksamhet ger ett tillfredsställande kundskydd. Tidigare fanns endast lagregler beträffande försäkringsmäklare som var tvungna att agera oberoende av försäkringsgivarintressen. Den 1 juli 2005 trädde dock en ny lag i kraft, lagen om försäkringsförmedling (2005:405), som har ett vidare tillämpningsområde än den äldre lagstiftningen om försäkringsmäklare.
