Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

The structural rationalization of the agricultural sector in Sweden has led to many expansive, professional companies orientated towards growth. The agricultural sector is a very capital-intense sector and is characterized by the need for large sums of capital in form of buildings, inventory and arable land. The capital need is especially large for companies who have an ambition of growth and development of the company in the near future. The study is built upon six cases that all can be categorized as large agricultural farms with a turnover exceeding 20 million Swedish crowns. The companies are located in the middle and in the south of Sweden and are in the sector of primary production with focus on dairy-, pork-, egg-, chicken-, beef-, vegetables- and grain production as well as in the business of refining milk towards consumers. The study aims to identify the motives and driving forces that lies behind the growth of a farm-based company. The agricultural companies' motive for growth is studied based on which factors that influence the ambition to grow and to what extent these factors accord to the picture given by earlier research of small companies outside the agricultural sector.

The purpose of this study was to investigate the occurrence of Verotoxin-encoding bacteriophages in mussels, cultured downstream the sewage treatment plant in Lysekil.Mussels were collected in three growing areas from April 2008 to March 2009. Real-time PCR was performed for detection of vtx1 and vtx2 genes and enrichment of bacteriophages on non Verotoxin-producing Escherichia coli O157: H7 was carried out. All samples in real-time PCR analysis were negative; no presence of Verotoxin-encoding phages was shown. No plaque was formed on blood agar base plates, indicating that no bacteriophages had been taken up by E. coli bacteriaThe levels of Verotoxin-encoding phages and E.coli outside the sewage treatment plant in Lysekil were not high enough to be able to form VTEC in mussels, indicating that the faecal contamination was low.

This thesis is using the theory of participatory democracy to show how one can work to increase the participation in the society, between elections as well as during elections. For a couple of years now many traditional democratic countries have been struggling with low voting rates. Hence this, I find it interesting to study what has been done to cope with this problem. The government in Sweden had a project working on how to make more people involved in the democratic process, especially people that to a lesser extent participate in this process. In this thesis two projects will be studied, Möllevångsgruppen and Unga väljer Miljö i Malmö.

?This is a study of two school extern homework activities dedicated to helping students with their homework. The questions at issue are 1) how are the homework activities organized when it comes to financing, planning, marketing and implementation? 2) Who participates as staff as well as students and what are the requirements for participants? 3) What are the reasons for students to attend school external homework sessions? Material was gathered by a survey among the students at the activities and by interviews with principals for each activity. Two main findings are that the homework activities are almost exclusively visited by students with immigrant background and that the main reasons for participating are difficulties with the Swedish language, and parents not being able to help their children with homework.

Feline infectious peritonitis (FIP) is a feline viral disease with high mortality. There is no cure or any effective vaccine available today. Many questions are yet to be answered about this disease and the immune response in affected cats. The aim of the study is to evaluate two different techniques for the study of cytokine profiles in cats vaccinated with a vaccine concept against FIPV. More information about the immune response in these cats could give valuable information to better understand the pathogenesis of the disease and the development of an effective vaccine.

The object of this study has been to establish whether there is a correlation between a teachers efforts in presenting, working with and creating a connection to ?real life? when working with fictional texts. A further hypothesis is that presentation, realization and the follow up activities has a correspondence to how well the goals for the lesson are achieved. In order to achieve the presented objects the methods of observation and interview are chosen. Firstly classroom observations are made and subsequently interviews with teachers that struggle with these questions on a regular basis are conducted.

Svensk titel:  På återseende om 20 år?Hur hålls relationen mellan kund och företag vid liv på en sällanköpsmarknad?- en studie av HusmanHagbergs relationsmarknadsföringEngelsk titel:  Will we meet again in 20 years?How does the relationship between a customer and company survive on a ?rarely buying market?? ? a study of the relationship marketing of HusmanHagberg Författare:   Emma Anderberg och Maria ÖhmanFärdigställd:  2007Handledare:  Nazeem Seyed-MohamedAbstract:During recent years a focus on the development of good and long-term relationships with the customers has replaced the single transactions that which have been the goal when using traditional marketing methods. To succeed on a tough and competitive market it is important for companies to develop good and long-term relationship with their customers. Working with relationship marketing within the estate agent market is especially complicated in many ways. An estate agency is a service company and works as a middleman between a buyer and a seller and therefore has a complicated relationship to its costumers.

This paper analyzes the Swedish labor market during the interwar and early postwar period within the framework of modern labor market theory. The development of unemployment during this period - according to the commonly cited source of labor union reports - represents a conundrum for research. The unemployment rate rose after the initial diverse shock of 1921 and stayed at a permanently higher level for the rest of the interwar period. This development was reversed after World War Two when the unemployment rate decreased and stayed permanently low for the rest of the postwar period until the oil price chock of the 1970s.In a first step the available sources of unemployment statistics is investigated and compared. The general conclusion is that the labor union reports overestimate the level of economy wide unemployment while being a reasonably good indicator of movements in the rate.

AbstractThis bachelor thesis was performed at the Royal Institute of Technology in Stockholm on behalf of the Land Survey Authority. The thesis is about fish conservation and division of fishing water at official duty. It is the Land Survey Authority that examines division of fisheries, but before a case can be implemented, certain requirements must be achieved such as FBL 3:8, which prevent divisions that are deleterious for fish conservation. The purpose of this thesis is: to obtain a clearer view how FBL 3:8 should be applied in practice, how the application differs between the offices in central Sweden, and how fish care is regulated at both international and national levels.At an international level, in EU the commercial fishery is regulated through the common fisheries policy (CFP). The fisheries policy consists of a reform that will last for 10 years.

This thesis treats a new perspective in the theory of classification, the context-based approach. The aim is to find out what kind of value this new approach can have in the process of creating a classification scheme for a special library collection. The first question to be answered is how the context-based approach works in a real life. The second question investigates which role the research in this particular area might have. Illustrating a real-life situation, the unit of Rättsmedicinalverket in Linköping serves as the object of study.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

ABSTRACTA defect implantation process is the major reason for unexplained infertility. Estrogen andprogesterone are steroid hormones preparing the endometrium for implantation. They mediatetheir effect through their receptors: estrogen receptor alpha and beta and progesteronereceptor A and B, respectively. Leukemia inhibitory factor (LIF), which is also important forimplantation, mediates its effect through LIF receptor and the coreceptor, gp130, and is downregulated by suppressors of cytokine signaling 1. The aim of the study was to compare thelevels of the steroid hormone receptors and LIF related factors in the endometrium of twogroups of women with the diagnosis unexplained infertility: one that became pregnant afterassisted reproduction and one that did not become pregnant.
