The purpose of this work was that with the help of a literature review have a single document with information on how the various species: brown bear (Ursus arctos), lynx (Lynx lynx) and the wolf (Canis lupus) living in the wild. The aim was also to show which stereotypic behaviours these different species have in zoos and the enrichments that is already being used and to make suggestions and recommendations on enrichment based on animal behaviour ecology. In zoos, some species thrive well while others have propositions to propagating problems, poor health and stereotypic behaviors. The brown bear, lynx and wolf, live both in the wild and in zoos in Sweden. As these animals have different ways of living in the wild, it is important to accommodate to each species, the way they are kept in zoos in accordance with their behavioural ecology.Brown bears are omnivorous and solitary living species with large energy needs so that they spend most of their day to actively feeding but also rest.

Predicting corporate failure is an increasingly important topic in the world of economics today. This paper, with the help of the credit ranking company Syna AB, aims to investigate a few different statistic strategies to do just that. This task is accomplished by using a data material of 250 000 Swedish companies divided into two subsamples. The first sample is used to develop the model and the second as a validation sample. The model developing sample holds 160 000 companies divided into five different subgroups based on size and age.

To fit into our society the dogs of today need a good mentality. To investigate their mentalitydifferent behavior tests have been developed. The tests are useful tools in the selection ofbreeding animals as well as for working and companion dogs. To counter the demand for atest that could be suited for all kind of dogs, regardless of their future function, the mentalitytest Beteende- och personlighetsbeskrivning hund (BPH) was developed. BPH consists ofseven subtests that expose dogs to various situations that can be found in everyday life, suchas meeting an unfamiliar person, sudden noises and suddenly appearing objects.The aim of this study was to find out if there are differences in physiological values betweenindividuals, validate the behavior observations during BPH and get aware of how the dogsexperience the situation.

The last couple of years the use of Internet has changed in the way that the web pages can be affected of the person that uses them. Because of this dynamic Internet technology has emerged that makes it possible for a web page to receive information from a web browser. This information can then be used to affect the appearance of the page. PHP and ASP are two dynamic Internet technologies. They are integrated in HTML and are executed on the web server.

Antalet kretskort som monteras i multikortssystem, till exempel telekommunikationssystem, ökar ständigt. Samtidigt som ytmonteringstekniken och packningstekniken blir allt bättre utvecklas även tillverkningsmetoderna för olika integrerade komponenter, vilket medför att varje kretskort rymmer allt fler integrerade komponenter. Detta gör att testning av integrerade komponenter och multikortsystem blir alltmer komplex. En förutsättning för att kunna genomföra effektiv testning är standarder. Standarder över hur testning ska genomföras medför att en komponent som uppfyller kraven från en standard är direkt utbytbar mot en komponent från en annan tillverkare som uppfyller kraven från samma standard.

Aggression between laboratory mice is a common problem and can result in welfare issues such as mice hurting or killing each other and also stress. Swedish laws and regulations clearly states that mice must be housed with a companion due to their natural social structure. Many studies have investigated the effect off enrichment, group size, cage size and other potential changes in in their environment on the occurrence of aggression. Even with these changes aggression can exist and therefore a new solution was tested in this paper. The proposed solution was to house an intact mouse with a castrated one and thus fulfill laws and regulations while still maintaining the physiology of one of the mice for the purpose of medical experiments.

This paper aims to describe the variation and develop a method to control the production for the product Metropol Kaktus from the snuff developer Fiedler & Lundgren. We are going to use the requirements from the product specifications as limits of the expected quality when we present methods to control the process. One method attempts to control during the process and the other attempts to maximize the number of products with strived quality before the process starts. Metropol Kaktus is a product produced with high quality, the mean weight is 20,023 gram and this is very close to the weight, 20 gram, which is reported in the product specifications. The variation in weight variable is less than what is reported in the specifications and the minimum weight is over the limit set by Livsmedelsverket.

The official statistics on communication and transports in Sweden is administered by Statens Institut för kommunikationsanalys (SIKA). SIKA?s commission includes production of statistics on the Swedish vehicle fleet. These statistics provide important information tofinancial institutes, ministries, industry and mass media among others. Furthermore, the vehicle statistics include measures of comparison between different counties and municipalities.

Social media provides a new position of power to the single individual within PR and marketing campaigns. When a company uses social media as a communication tool in their PR and marketing practice, they have to adapt themselves after the customers' needs and the new communication structure within social media. Communication in social medi is different from traditional media, which is more one-way communicative and visual in its interaction, rather than the digital media that are more two-way communicative av viral through dialogue. If a company creates PR and marketing campaigns within social media without adjusting to the new rules of communication through dialogue, and instead try to apply traditional one-way communication to their social campaigns, they put themselves and their brands in risk of public humiliation and loss of customers; the speed of the viral dialogue over social media can spread bad news fast, and with the newfound power of the single individual, the impliacations can thus be devastating for a company and its brand. If an organization does not respond and take part of the criticism that may be directed at them through the customers' comments, the negative dialogue among clients and the public within social media can quickly create a hazard enviorment for a company and its brand to be seen in. The public within these social media platforms are more independent and continuously conversing with each other on a local an global scale.

In this essay we aim at finding an appropriate flash estimator of the quarterly Swedish private consumption (PK). With the aid of the statistics program TRAMO we study if monthly data from the consumer survey (HIP) and retail industry (DH) can be used in a transfer function model (TFM) to forecast PK. In the work of assessing the state of the market and the business trend, fast information from the national accounts is needed for making decisions for the economic politics in Sweden. A way to speed up the information process is to use leading economic indicators to asses this development. Another way to get information faster is to use a flash estimate.

The purpose of this thesis is to investigate the possibility to make small, cheap and ultra low power sensor platforms, connected in wireless networks for monitoring of home and industrial environments. The concept is based on ideas from our supervisor, Jerry Lindblom. The developed system consists of a generic platform for different sensors, a receiver and software. A GPRS module from RO Rollytech AB and a database from Gema Industri AB have been modified and used to demonstrate an example of a complete system. To the platform, it is possible to connect any resistive sensor and any sensor that can act as a switch.

The current situation for Swedish grain farmers facing a situation with decreasing profitability makes it necessary for the farmers to find ways of increasing the margins in their grain growing. Decreasing profitabilities along with Lantmännens closing of grain elevators contribute to the necessity for farmers to invest in grain storing and drying at the farm. By investing in capacity for drying and storage of grain on the farm it is possible to recieve a higher price on the grain sold due to the possibility to sell when the price is higher compared to the harvesting season. An investment in grain drying and storage with a relatively low investment cost that recently has appeared on the Swedish market is the grain stir drying system. This study contains a comparison of an investment in a grain stir drying system where the grain is dried and stored in the same silo and a conventional drying and storage system.

Boberg at Scania CV AB. The purpose was to investigate the technical and customer oriented possibilities for the development of a transport security measure against cargo crime, which is a growing problem in Europe. The main goal was to develop a concept that is possible to implement in the Scania CV AB Fleet Management System. Another goal was to develop a security model that will be used as a tool during Scania CV AB?s future development projects of transport security concepts.The work was divided into three main parts: a background study, handling cargo crime, transport security Scania CV AB trucks and market analysis, a stakeholder investigation including a questionnaire and interviews, and a concept development session.

The district heating load is seasonally dependent, with a low load during periods of high ambient temperature. Thermal energy storage (TES) has the potential to shift heating loads from winter to summer, thus reducing cost and environmental impact of District Heat production. In this study, a concept of high temperature borehole thermal energy storage (HT-BTES) together with a pellet heating plant for temperature boost, is presented and evaluated by its technical limitations, its ability to supply heat, its function within the district heating system, as well as its environmental impact and economic viability in Gothenburg, Sweden, a city with access to high quantities of waste heat.The concept has proven potentially environmentally friendly and potentially profitable if its design is balanced to achieve a good enough supply temperature from the HT-BTES. The size of the heat storage, the distance between boreholes and low borehole thermal resistance are key parameters to achieve high temperature. Profitability increases if a location with lower temperature demand, as well as risk of future shortage of supply, can be met.

To understand the motives, and perhaps more importantly the barriers, for farmers to convert from conventional to organic farming is of great interest for policy makers as well as for academics. In Sweden and in other EU countries, proposed targets of the area in organic farmland have failed to be reached in spite of different kinds of policy measures. Most studies agree that the average profitability seems to be comparable to or better in organic than in conventional farming. This would indicate that there must be other factors of importance which can explain the low particiapation rate. A higher perceived risk in organic farming with respect to yield and price is frequently brought up as a potential explanation within a qualitative framework.
