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.

When building a house or similar the stress on the ground increases and deformations can arise. The deformations create a foundation that the building is not constructed for and damages on the building arise. The increased stress on the ground can be derived back to the building, but it is possible that the increased stress may well derive from different sources such as other buildings or trees.       The building is an older property, built in the late 19th century alternatively early 20th century, and is today used for rental housing and has suffered severe damages due to subsidence. The goal of the thesis is to find possible causes for these subsidences. The thesis was executed as a combination between literature- and casestudie. After careful studies it has been found that a probable cause for these subsidences is trees. Through field- and lab studies it has been found that the trees has effected the ground through there accumulation of water.

The aim of this report is to discuss computer security in handheld computers and to find out the appropriate security level that must be implemented to be able to use handheld computers within the Swedish healthcare system. Most healthcare centers are using some kind of electronic journals for their patient´s data today, but there are still a number of clinics that are usingthe old paper-system. On a few places in Sweden the use of handheld computers at the clinics has already started, but in the United States the use of handheld computers in the medical area is already widespread and from this we can see a lot of different situations where it is useful and effective to work with handheld computers. The security demands on patient´s journals are high and regulated in both Swedish law and regulations from the National Swedish Board of Health and Welfare. The law does not have any substantial demands, but states that there should be an adequate security level based on the nature of the information and the costs.

This essay examines middle school students? understanding of a text read aloud to them in English and the connection between the degree of listening comprehension and the expected increase of vocabulary throughout middle school. The same listening comprehension test was carried out in grades 4, 5 and 6 in a middle school in order to survey differences in English listening comprehension in regard to the ability to reproduce the content of an oral text. The result shows that there was a progression from level to level when it comes to comprehension and the number of words reproduced and that this progression was most noticeable between grades 4 and 5..

I was assigned to the thesis as part of a project GMA AB (Ground Machinery Applications AB) is running. The project aims to develop a new method for injection of drilled holes in rock walls. Currently, the injections usually involve cement but the basic idea of the project is to replace cement with a supplement called Silica sol.Silica sol is known as a gelling liquid. The gel time is controlled by a mixing of saline. Depending on the amount saline that gets mixed in, the gel time varies.

This graduation thesis is about baths and beach like places in city centers. It focuses on recreation and the creation and development of public, social spaces in the city containing water as a visual and useable element. The thesis is divided into three parts; background, inspiration and application. The background examines four factors which we consider important for the occurrence of inner city baths; water, the history of bathing, inner city recreation and social life in public places. A discussion of the (future) importance of inner city baths and beach like places' is then presented. The inspirational part is divided into examples of existing places and examples of types of places. The first is used in an attempt to examine the function and importance of inner city baths and beach like places as well as the opportunities and challenges associated with them. The latter contains a presentation of six categories developed by us to facilitate the planning of inner city baths and beach like places.

Using stimuli with identical information in both PR and advertising, this study seeks to explain how content class together with the level of involvement affects the communication effects of marketing messages. There is currently no established way of measuring the value of PR, and contemporary PR metrics do not take into account what effects PR actually generates. PR is often said to have an advantage over advertising due to the effects of third party endorsement, but previous empirical assessments show inconsistent results regarding what effects each content class generates. The result of this study is that PR is stronger at building recall, interest and credibility, and that it has less perceived selling intent than advertising. Results differ somewhat between different levels of involvement, but the conclusion is that this might not be attributable to the level of involvement per se but rather to the type of products being used in stimuli - a conclusion that seems valid for previous research as well.

Slopes in fine till soils are exposed to surface erosion due to rainfall, snowmelt and upland water sources. Large areas of road slopes are therefore covered for surface erosion protection. Preventive methods like ditches and trenches are also being used. Silt tills are particularly troublesome since the water can bring the soil into suspension and cause mudslides. Different methods for erosion protection have been studied in this work, with the emphasis placed on rockfill covering. The need for and the dimensioning of this type of covering has been examined in literature and field studies.

The stability of railway embankment is essential for safe transport. In order to ensure safe transport, water should be allowed to freely drain. Furthermore, as the engine driver has to be able to see signs, and people working on the embankment are supposed to easily see flaws on the rails to ensure safety for the passing trains, plants should not be allowed to grow on the embankment. In Sweden there are 12 000 kilometers of railway tracks and 25?30 % of them are treated for weed control every year.

Already in 1988, different levels of participation in the election between different districts of big cities in Sweden were noticed. The problem with low political participation in specific areas has almost always been theoretically explained through an individual perspective. This study is therefore focusing on the problem from a contextual perspective. The hypothesis for the study is as follows, in the case of Malmö the level of participation in elections are affected by social environment in which segregation will be the single highest factor. The dependent variable, participation in the election was tested by the independent variables representing social environment; origin, education, gainfully employed and income.

Abstract In the contemporary world of information technology you find a multitude of applications and systems covering a broad spectrum of areas of need in different companies. One effect of this multitude of programs is the difficulty to make them exchange information with each other or to collaborate, since they are developed by different programming languages for different platforms, with different standards and different data formats. Our aim with this work is to describe how it is possible to tie these programs together to make them actually communicate with each other in order to exchange information, share their native methods and also to become a part of the overall business processes. In this integration task you will, among other things, find different levels of application integration such as data level, method level, application interface level and user interface level integration. Application integration also involves hardware components, called middleware, that facilitate the physical connection between applications.

Dagens grafikkort är uppbyggda av kraftfulla multiprocessorer som gör dom ypperliga för att hantera parallelliserbara problem som skulle ta lång tid att utföra på en vanlig processor, så som exempelvis level-of-detail eller raytracing.Denna rapport presenterar en parallelliserbar level-of-detail algoritm för terränghöjdkartor samt implementerar denna för användning på grafikkort användande Nvidias CUDA API. Algoritmen delar upp den totala höjdkartan i sektioner som ytterligare delas upp i mindre block som beräknas parallellt på grafikkortet. Algoritmen räknar ut vertexpositioner, normaler och texturkoordinater för vardera block och skickar datan till applikationen som skapar vertex och indexbuffertar och renderar sektionerna. Implementationens prestanda och förmåga att reducera trianglar analyseras med två olika sorters culling-metoder; en metod som gallrar trianglar på sektionsnivå och en metod som gallrar på blocknivå.Resultaten visar att det är mycket fördelaktigt att låta grafikkortet hantera level-of-detail beräkningar på detta vis även om minneskopiering över grafikkortsbussen är ett problem, då det tar upp ungefär åttiofem procent av den totala tiden för att hantera en sektion. Beräkningarna i sig tar väldigt lite tid och det finns gott om utrymme för utveckling för att uppnå en så bra fördelningen av trianglar över terrängområdet som möjligt..
