Abstract The accident in 1986 at the nuclear power station in Chernobyl, Ukraine, dispersed radioactive cesium over large areas of Europe. The half life of 137Cs is 30 years and this radionuclide also behaves like potassium, which means that it can easily be taken up by the vegetation or be adsorbed in to the structure of clays, principally illitic clays. When radiocesium decays ionizing radiation is emitted, which is harmful to humans that are exposed, either directly or indirectly through food intake. It is there-fore important to know what happens to the cesium that is dispersed into the environ-ment. In this project a simulation model was constructed to simulate the adsorption and transport of radiocesium in the soil and plant uptake.

This paper is a literature study aiming to describe scientists newest theories andknowledge concerning the El Niño and Southern Oscillation. Firstly I have described the?normal? conditions with rising and sinking air in Hadley- and Walker-cells in theequatorial Pacific and from there moved on to explaining the reversed circulation patternsand higher sea surface temperatures (SST) leading to rising air and anomalousprecipitation in eastern Pacific constituting the El Niño phenomenon. My outermostinterest regarding El Niño has been the associated teleconnections, especially in nontropicalareas. I have described the El Niño effect on the Indian summer monsoon, ontropical cyclones and on storms and precipitation on higher latitudes.

An overwhelming majority of all male piglets are castrated without anaesthesia when they are very young. In Sweden this means that approximately one and a half million piglets are castrated every year. The reason the piglets are castrated is the strong and unpleasant smell and taste, the ?boar taint? that the meat from intact boars sometimes exhibits. Boar taint is chiefly cause by androstenone and skatole, two compounds that are mostly produced by sexually mature boars and are accumulated in the subcutaneous fat.

Food-poisoning is a major health problem and an estimated half a million Swedes are food-poisoned annually, with acute gastroenteritis as a consequence. One of the major causes of contaminated foods is related to food- and waterborne viruses. To be able to trace back the source of contaminant, the method of detecting viruses must be specific and sensitive. No standardized method for detecting foods for sapovirus exists today. The aim of the work described in this bachelor thesis is to implement and opti-mize a real-time RT-PCR method for the detection of all genogroups of human sapovirus in foods.

This paper constitutes graduate work at the landscape architecture program at the Department of Urban and Rural Development at the Swedish University of Agricultural Sciences, Uppsala. The main purpose of this paper is to create a project from an idea to reality. The place for the project is the environment of Icehotel in Jukkasjärvi in the north of Sweden. Icehotel is a unique hotel concept and each winter a hotel, a church and a bar is built at the area of only ice and snow, and each spring it all melts down and returns to the Torne river. During the project a plan for the environment, in ice and snow, will be made and then a part of it will be built in January 2010. The purpose is to improve the outdoor environment with landscape architecture to enhance the experience of Icehotel and create an exciting entrance to the area.

The UN was established after the Second World War. The organization?s primary goal was to maintain peace among all nations. When the UN intervenes in other states affairs, it is violat-ing the principles it is set to defend, principles of non-intervention and respect for sover-eignty. The outcome from such interventions is very important, a result that can legitimize the action.

The purpose of the study was twofold: to describe the audiologist's working process and to explore patient records written by audiologists according to structure, content and comprehensiveness. Method. Out of rules and regulations, code of ethics and literature concerning audiological rehabilitation from the audiologist's point of view, a model for the audiologist's working process was developed.

Almost half of the population in Sweden suffers from obesity and the cases of eating disorders are increasing. We are exposed daily to the belief that losing weight will make us happier and it will just be through this particular diet. Even if it has been proven that short dieting plans like ?lose 20 pounds in one month? doesn?t give a long-term result, society continues to buy into the idea that they do.Every day 16000 placards are placed around us in Sweden with loud yellow colors and big black letters which make them almost impossible to avoid. Their main purpose is to attract and get as many people as possible to buy single copies.This essay deals with several questions: How diet tips figures on placards and how this has developed through years.

Of the meat substitutes were 28 only available for business clients.

The Swedish energy system will be influenced by many future changes, such as energy and climate policy objectives. The installation of more renewable electricity could increase by using solar energy. Over the recent years, grid-connected photovoltaic (PV) systems have increased dramatically in Sweden, partly due to various support systems and compensation models. These support systems have been designed to make it easy for individuals and businesses to invest in self-generated electricity and thus contribute to the transformation of the energy system.The introduction of a higher proportion of solar energy may in turn affect the Swedish electricity system. This could mean that the electricity companies will be facing a number of changes in the near future.

The cost of transportation has strongly increased in the recent years, transportations which are a major part for the construction companies. Skanska Asphalt which is a part of Skanska Sverige AB has noticed that there are significant cost savings to be made with the purchasing of transports. The transports in this case is about asphalt, where the costs are about 10% of the outsourcing business turnover. The purpose of this thesis is to study the working practice that Skanska Asphalt are using today in controlling and time-writing, for the asphalt transportations. Resulting in recommendations on how to improve the working practice at Skanska Asphalt.This study was conducted with the help of a number of interviews with Skanska?s employees and with suppliers of transportation to describe the practices which are being used in during the asphalt transportation.

The city of Uppsala and its surroundings are a very expansive area. A prerequisite for a sustainable development of the area is well-functioning supply of drinking water. In Uppsala municipality, the Uppsala esker and Vattholma esker are the groundwater storages for drinking water. Besides the eskers, other sources of qualitative groundwater in the Uppsala municipality are relatively poor and more than half of the area consists of ground conditions with a risk of saline groundwater. The neighbourhood of Vreta-Ytternäs is situated 10 km south of Uppsala, in the area with risk of saline groundwater but outside the municipal water supply.

Bachelor thesis in business administration with emphasis in accounting and auditing. Spring term 2011, Mälardalens Högskola.Authors:Jim Hansson, Filip Sahl and Pererik Sewerin.Advisor:Lennart Bogg.Key words:Abolition of mandatory auditing, optional audit, auditor, audit.Title:The role of audit in a credit review - impact from the creditor's perspectiveBackground:As of November 1st2010, auditing became optional for micro companies in Sweden. This leads to an opportunity for about 70 % of the joint-stock companies to choose whether or not to keep their auditors. Creditors are affected by this as they may receive a less trustworthy base to make a good credit review if many companies choose to proceed their accountings without the control of an auditor. Creditors have the option to require that companies are to be reviewed by auditors, while authorized accounting consultants may be a possible substitute as a quality control for the accountings.Purpose:The purpose of this thesis is to examine what impact optional audit has had in credit processes so far and look into alternative forms of reviews for businesses.Problem definition:? Does auditing simplify for the creditors in a credit review? ? Is there some kind of accounting that could be a substitute for the audit?Method:The study is qualitative in character through six interviews.
