Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In addition, to enable frequency and voltage scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency scaling capability into OSE RTOS, a software module hasbeen developed for this operating system.

The last few decades the development in the field of electronics has been huge. The components performance gets better at the same time as the manufacturing cost decreases. Many of the design moments that have to be done, are done automatically today, but it can get better. Especially for analog circuit design.At Electronic System in Linköpings universitet, research is in progress to develop a tool that can design analog circuits in reasonable time. It means that it has to size the components (transistors, resistances, capacitances etc), so that the circuit can fulfill the performance requirements.

The aim of the study was to describe parents' experiences of empty nest. The sample consisted of individuals who had experienced one child moving out of the parental home. Data were collected through qualitative semi-structured interviews and were analyzed by using thematic analysis. The thematic analysis revealed four themes, Concerns about the new time in life, Changing roles, Socializing in the family and Testing the relations. Due to the themes participants' stories reveal anxiety facing the time that will come when children takes the step to leave the nest.

The residential yard at Kvarteret Landsfiskalen 1, in the area Herrgården in Rosengård, Malmö was built in 1971 and has since then been reconstructed twice, in 1984 and 2008. The yard is found in an area which was built during the years 1965 ? 1974, a period in which the swedish goverment approved a decision to build one million homes, and much of the events in this particular yard is also typical for the process in many other areas built during the same period.At the original construction the design of the yard was entirely incused by the pressure in time and finance, one was under at that time, in order to over- come the housing shortage. The design it has nevertheless been given, reflects the esthetic ideals of that time well.The building of the area was barely finished when the swedish authori- ties started handing out grants in order to support the rearmament of the outdoor environment in the areas built during the so called ?million program?.

The purpose of this study is to investigate whether there are any similarities or differences between leisure-time pedagogs and primary school teachers' verbal communication with parents. Questions we ask ourselves is how the verbal contact looks like today, the desire for how it should be and the importance of verbal communication has.We chose to make a qualitative questionnaire study in the form of open questions to three leisure-time pedagogs, three primary school teachers and eleven parents were asked to answer.The results show that leisure-time pedagogs, primary school teachers and parents believe that verbal communication is important and significant. They believe that it is working well today, whether is via face to face, telephone or email. The verbal communication should be honest and straight between all parties. Parents believe it is important to know leisure-time pedagogs who take care of their children, in order to create a sense of security among parents.

The fork lifter chipper truck is a concept which has been developed for harvest and transport of bio fuel. The system consists of one fork lifter chipper truck and 1, 2 or 3 transport lorries, usually two, which serves the fork lifter chipper truck. The system is driven by the fork lifter chipper truck that produces chipped material into a container on the truck. When the container has been filled the truck drives to the landing site where it?s offloaded.

Aim: The aim of this study was to describe what nurses experienced in connection with waiting time related frustration among patients and relatives in the emergency department and also what strategies nurses use to manage waiting time related frustration.Background: The numbers of emergency department visits are increasing and lead to waiting times which can cause frustration among patients and relatives, a frustration that nurses encounter in their everyday work and need strategies to deal with.Methods: This is a descriptive qualitative study. Interviews are conducted with five nurses, transcribed and analyzed by qualitative content analysis.Findings: The nurses feel inadequate and powerless when they meet patients and relatives frustration. In order to deal with patients and relatives frustration, they use the strategy of participation, which implies to involve and meet patients and relatives needs for information and to be seen. In order to prevent themselves becoming frustrated they use adaptability, by creating an inner calm, not take it personally and to distance themselves from the frustration.Conclusion: The result highlights the importance of managing the activity to reduce waiting time related frustration, for example through reflection and working for reducing waiting times. Further research is also needed..

To turn the dairy heifers out on pasture is the most natural way for the cattle to get feed. At the same time it is cheap and if it is right treated a feed of high nutritive value. The problem today is to get dairy heifers to grow enough when they are grazing at natural pasture for the entire summer. Therefore, the opinions differ whether pasture is a resource or a problem. The increasing interest of pasture production is due to the fact that you can receive grants for preserving valuable natural assets and cultural landscape elements in the pasture land. A high grazing pressure is necessary to preserve an open landscape and a great variety of species. In the same time the heifers have to supply their nutritive needs in order to grow and be large enough to show heat and be pregnant in right time to calve with a sufficient body size and at an economically right age. This paper includes a literature review on natural pasture, pasture production, and growth of dairy heifers together with own interviews with dairy farmers about their point of view to the pasture husbandry on the farms, how they plan for pasture, look after natural pasture, treatment areas and take care of the calves and heifers. The results indicate that the time it takes and the demanded work are the biggest factors to how and why the farmers do as they do..

Since the 2006 election, the debate surrounding the Swedish labour market policy has intensified. There has been a discussion about a need for change towards a more flexible labour market. An example of this is on the other side of the strait, in neighbouring Denmark. Their flexicurity model, ?the golden triangle?, is characterized by a flexible labour market, generous unemployment benefits and active labour market policies.

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.

Our study shows if and how Swedish public service television has changed its content from the time when SVT had monopoly until this day when the competition is greater than ever. We got an insight in what has been presented to the audience by studying TV schedules from 1975 to 2009. The study examines four weeks during the years when the two main channels SVT1 and SVT2 have been broadcasting. One week each of these following years have been examined: 1975, 1985, 1995 and 2009. These years have been chosen to get an insight in what content the TV schedules presented before and after SVT got competition in the Swedish TV market.

 AbstractThe aim of this essay is to look into how teachers view pupils who use finger arithmeticduring mathematic classes. How do these teachers help them to move on with their learning,what information and problem-solving material do they use?I made qualitative interviews with grade two- and grade three teachers, in three schools.The interviews showed that the teachers find it difficult to adopt a suitable attitude towardsfinger arithmetic. In addition, lack of time for planning and lack of knowledge about variousexperimental methods caused further predicaments. The teachers were aware that arithmeticexperimental material was attainable at the schools, but time to learn about it and how to useit was lacking.

Background Calprotectin is a protein expressed in the cytoplasm inside the neutrophile granulocytes. During inflammatory bowel disease (IBD), the neutrophile granulocytes are involved in a complex interaction at the inflammatory area where they die and release their content into the intestinal lumen. Therefore, calprotectin in stool is a suitable marker for diagnosis and measurement of the disease-activity in patients with IBD. The most commonly used method to detect calprotectin in stool is ELISA, but the process of manual preparation of stool samples is time-consuming.Aim The objective of the study was to evaluate an extraction method that could replace manual preparation of fecal samples and to compare different methods for measuring Calprotectin in stool using two ELISA-methods from two manufacturers and one rapidtest.Methods For extraction of calprotectin from stool samples we used sample collector tubes from Epitope Diagnostics and fecal preparation kits from Roche. Two different ELISA-kits for measuring calprotectin concentration in stool were compared.
