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.

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.

This study was a degree in Master of Science in agriculture with specialization in animal science for the Department of animal nutrition and management at SLU. The subject was created by AS-Faktor, a small company for science and development within the company Lantmännen AB. It was a test of the effect of SPC (Special Processed Cereals) on induction of the endogenous protein AF (an antisecretory factor) in plasma and intestinal lumen in broilers. Previous results have shown positive effects on different intestinal diseases in pigs, horses, dogs as well as in humans. Beside the induction we also studied the effects on results in a conventional slaughter chicken production, including the ability of SPC to compete with or be affected by the coccidiostat, Salinomax.When diarrhoea occurs, it's because there is an imbalance between the secretion and the absorption and it can be caused by for example toxins.

This survey was made during the autumn of 2002 and the beginning of 2003, on commission from the National Board of Forestry. The purpose with the survey was to gather experience and knowledge in the organisation about fencing and this was made through interviews. The ambition was also to get knowledge from people outside the organisation that have great experience of forestry and fencing. The interviews were based on questions that have been composed by the author with help from the supervisors. The questions were the same to both the personal from the National Board of Forestry and to the foresters. Interviews were also made with private landowners, gamekeepers, game researcher, the County Administrative Board, the National Road Administration, pole and net retailers and contractors. The target group for this work is the National Board of Forestry to be forwarded to persons interested in forestry with the ambition to spread knowledge about how to prevent damage on the forest by browsing animals. The deer populations are big in the south of Sweden and growing populations have increased the damage on plantations of broadleaves of the most species.

There are records of lowering of the water level in a lot of the Swedish lakes from the middleof the 1700th century. The aim was gaining more areable land to meet the needs of more foodto support the expanding population. In areas with top soil which contents of clay or loam asin the southwest of Scania in southern Sweden this was proven to be a successful wayexpanding the total outcome of the harvest.The studied area in the northeast of Scania, though, consists of morain with a lot of mires -much less nutritious conditions. When the water level is lowered the atmosphere gets accessto the peat. The dissolving of the organic matter that has been suppressed by the lack ofoxygene below water level continues.

A couple of hundred years ago half of the earth?s surface was covered by forest. Today, only half remains and every year an area the size of Nepal is disappearing. Deforestation, together with the burning of fossil fuels, is also one of the reasons for the increasing greenhouse effect. Another relatively unknown problem for the world?s forests is the trade with illegally harvested timber.

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.

This work is a GIS study of fishing rights distribution between different categories of ownersand properties in the Stockholm Archipelago. The purpose was to create basic data used toestablish fishing laws and restrictions within the Stockholm County.Stockholm?s archipelago consists of a unique environment and is the natural life andreproduction environment for ? of Sweden?s reproducing fish species. The increasingpressure from fishing, tourism and weekend population increases the need for an efficientfishing administration to prevent impoverishment and to ensure the biological diversity inSwedish fishing waters. There is an increasing need to review fishing administrationmethodologies, as well as studying the categories of ownership and properties located insensitive areas and areas influenced by physical disturbances in order to establish effectivelaws and restrictions.The Swedish fishing rights for an area are currently not connected to the ownership of theproperty to which it belongs.

This graduate thesis is engaged with perceived safety and "safe making" design in public places. Despite the fact that we have never been as safe, questions of safety get more attention than ever in today?s society. Public demands for safer and more secure environments and low levels of experienced feelings of safety indicate problems in society that can shrink people's usage of public places as well as their quality of life. Through methodical exaggeration of danger and legislation of laws, the state creates a situation that in different respect work to overprotect the citizens, who are not unlikely to experience feelings of being unsafe at the same time that the actual safety is to big. An expansion of protection against fear can unlike what was first intended decrease the experience of safety.

During the early Middle Ages beech forests (Fagus sylvatica L.) spread out over large parts of southern Sweden. They had a crucial role in human survival for hundreds of years. For various reasons, the beech forest area has decreased since the 1600s. Spruce planted on former beech forest land was the primary reason for the decline during the second half of the 1900s, which made many worried about the future of the beech forests and led to a beech forest act in 1974. This study describes the background to the beech forest act based on parliamentary official documents.
