In the country of Jordan, egg production is very important economically, but several bacte-ria are involved in food borne diseases transmitted from eggs or other poultry products. The most important are Salmonella spp., Campylobacter jejuni and Escherichia coli. In Jordan two different housing systems are used for hens in large scale egg production; con-ventional cages and litter floor systems. Eggs from four different farms were analysed and compared to see if a difference could be found regarding the presence of pathogenic bacte-ria on the egg surfaces between these two systems. Total number of aerobic bacteria was analysed, the presence of Salmonella spp., C.

The Swedish immigration policy is a subject constantly under scrutiny, especially in the media. The Dublin treaty, which came into effect in 2003, has meant stricter regulations for the handling of asylum seekers, which in turn increases the requirements of the officials at the Swedish Migration Board. Consequently, the staff at the Swedish Migration Board is daily facing difficulties when deciding who is to stay or not. Therefore, it is interesting to investigate how these criteria in the Dublin Treaty, are used in the daily work of the officials. Emphasizing these problematic aspects of the Dublin Treaty, this study aims to answer the following two questions:- How has the Dublin Treaty been implemented in Swedish legislation by the officials at the Swedish Migration Board?- How do these officials work to implement this treaty?This case study is based on interviews with a number of officials working at the Swedish Migration Board.

Reasons for performing this study: Colic has for a long time been seen as a serious health problem in the equine population. Even so, the knowledge of colic seems to differ a great deal among the people interacting with horses. A large number of studies have for several years looked at risk factors that cause colic, in order to provide knowledge about them. The knowledge can then be used as tools for developing prophylactic methods in order to reduce the number of horses that develop colic. Objectives The aim with this study was to investigate if people have the correct knowledge about colic in horses, which risk factors that cause colic today and describe prophylactic methods that can result in avoidance of colic in horses. Method Eleven veterinary practices were contacted in order to send out two questionnaires for a study of six weeks.

Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.

The use of computer and video games has increased immensely over the past few decades and today a majority of the Swedish population enjoys them on a daily basis. With such a large number of frequent users, the media reporting on the subject of games becomes interesting and important. How are games represented in the media, and has there been any change in the way they are portrayed as their popularity has grown? ­The aim of this study is to determine if and how the portrayal of computer and video games in Swedish newspapers has changed during the period 1995?2012. The study was conducted with the use of quantitative content analysis and the empirical data was collected from the two most widespread newspapers in Sweden ? DN and Aftonbladet.

Suicidalitet, självskadebeteenden och psykisk ohälsa hos ungdomar är ett ökande problem. Antalet suicid i Sverige har minskat sedan 1980-talet. Men i åldersgruppen ungdomar 15-19 år har suicidantalen istället ökat markant. Suicidpreventiva åtgärdsprogram har införts för att på detta sätt försöka stoppa denna oroväckande utveckling. Syftet med detta fördjupningsarbete var att belysa ungdomars suicidalitet samt sjuksköterskans yrkesroll och förhållningssätt vid vårdandet av dessa ungdomar.

Destination marketing looks different from that of traditional marketing, since the product, in this case the destination, consists of several different parts compared to a good. A destination is marketed as a process where the consumption takes place at the same time as the production. Destination marketing organizations, DMO?s, are responsible for the marketing of a destination. Since destinations consist of several parts such as the train trip to the destination, restaurant visits, shopping, hotel stays etc., it is difficult for the DMO?s to fully control how a tourist perceive the destination.

To get rid of our dependence on fossil fuels we need to make use of renewable energy sources like wind power to a greater extent. Even though wind power is a renewable energy source it can still cause some problems for the close environment. One of the problems is shadow flickering. When the sun is low and the wind blows in a direction so that the rotor blades are positioned at right angles to the sunbeams and ?cut? the sunbeams off.

The aim of this thesis was to investigate if the robotized welding method FSW (Friction Stir Welding) could be applied for joining a rotating structure in an aero engine at Volvo Aero Corporation. FSW is expected to introduce less defects than today?s welding methods and could therefore be suitable for critical aero components. The material is the nickel based alloy Inconel 718, however a material experimentation is outside the scope of this report.The main goal of this study is to verify if the ESAB ROSIO robot based FSW-system has a suitable work space to be able to weld the rotating structure, and if the welding tool has accessibility to the joints. The FSW-process needs a rigid fixture, and a number of fix-ture concepts are presented based on a proposed weld sequence.

A totally mixed ration (TMR) is a mixture of all the necessary feed components for the cow. She will eat the exact same feed in every bite which will make the rumen pH more stable and always supply her with a constant proportion between roughage and concentrate. This will make it possible for the cow to eat more dry matter (DM) a day because the fibre requirements are fulfilled. If a part of the concentrate is given separated from the mixture it is called partly mixed rations (PMR) and is almost always used when using an automatic milking system (AMS). When using TMR and PMR it is important to have a high hygiene, be accurate when mixing the feed and to look after cows in a good and strict way. The aim of this study was to document different farms with PMR in an AMS to see which routines they have and how they are managing their production.

In forestry there are always needs of forest data to make good strategic decisions of different actions and economic winning. Usually this data gets from field-estimations made by forest workers with expensive costs and sometimes unsatisfied quality. StoraEnso Skog is a great forest company in Sweden and they have part of the responsibility of the forest own by Bergvik Skog. Bergvik Skog is owner of 1, 9 million hectares productive forest land. Both Bergvik and StoraEnso have great interest in new inventory techniques to get the important forest data. The company Foran Remote Sensing offers the opportunity with airborne laserscanning of forest and forest land. Foran got the mission of Bergvik and StoraEnso to laser scan Bergviks possession in Älvdalen, Dalarna.

Large areas of forests in the tropical region have during the last decades been lost and converted to new land uses while other areas have been degraded into secondary forests. These secondary forests need to be restored and rehabilitation through enrichment planting and liberation may help to speed up the recovery process. The objective of this thesis was to evaluate a rehabilitation method that includes enrichment planting, slashing of weeds and girdling of unwanted trees. The site for the project is situated in Sabah, Borneo in a secondary forest which had been logged and burnt by a wildfire. The project?s goal is to rehabilitate and increase biodiversity through enrichment planting of seedlings mainly belonging to the family Dipterocarpeaceae (dipterocarps).

The purpose of the study is to investigate and elucidate how low-cost airlines can influence and develop tourism in a region. In order to bring about the purpose the author used two research questions. Have low-cost airlines contributed to regional development? How many additional visitors have low-cost airlines contributed to Stockholm? In order to answer these questions a survey was carried out at Arlanda airport and statistics were collected. The results of the study show that there has been a regional development.

The purpose of this Master's thesis is to study metadata and its use at Web sites of six Swedish universities and colleges. Each Web site has been examined at three different hierarchical levels and the total number of examined Web pages is 258. 16 questionnaires have also been sent to webmasters at the six universities and colleges. The results show that metadata refers to the data which can assist to organize, describe, identify, locate, evaluate and retrieve resources on the Internet. Even though there are several different metadata formats available on the Internet, the commercial search engines only support the HTML's title tag and the meta tags with the attributes keywords and description.

This thesis describes redesign and adaption of a products housing. In order to make it more economical to produce at a lower production volume. The thesis is based upon a prototype that a previous student developed for injection moulding. The goal is to find alternative manufacturing methods, but also to identify parameters that affect the cost of the injection moulding tool.The housing must be tough in order to protect the circuit board inside. But at the same time it must allow sound, light an electrical communication to pass through.
