This report describes the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the heat storage that is active in a greenhouse.The computer model is used to simulate the thermal climate in a greenhouse under three periods, winter, spring and summer. It also investigates which effect a concrete wall has on the thermal climate in a greenhouse. The purpose of putting a concrete wall in the greenhouse model is to investigate the possibility to store heat during the day and then use this heat when the temperature drops during the night.The result from the simulations shows that a concrete wall levels the big difference in temperature that normally occurs under a day in a greenhouse.

This thesis aims to investigate the voting premium for companies differentiating voting rights between share classes on the Stockholm Stock Exchange. The voting premium represents the value of a vote attached to the share. The voting premium can be estimated from the price premium between two listed share classes with differentiated voting rights. Rydqvist's dissertation (1987) serves as a model for this study which investigates whether the theory of the so called "oceanic games", along with a proxy variable for cost of control, can predict the voting premium during 2010-2012. To the original model developed by Rydqvist, control variables for differences in liquidity between share classes are added to investigate for an increase in the explanatory power.

Many scientists agree that phytoestrogens could have an effect on the reproduction of an animal. The question is now why and what mechanisms that play an important role. This paper has been focusing on the estrus behavior of gilts by use of a behavioral study. Some of the gilts were given additional feed with the phytoestrogen genistein which commonly occurs in the feed as a part of soybean products. Blood samples were collected and analyzed for progesterone and estradiol concentrations.

In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.

The purpose of the study is to investigate how board structure influences CEO compensation for companies listed on the Stockholm Stock Exchange in 2004. The theoretical frame of reference is based upon the corporate governance theory, the principal-agent theory and previous empirical research in the area. A cross sectional regression analysis is used, where a number of control variables are included and significance tests are conducted. The study is based on information regarding CEO compensation, and possible factors affecting the compensation, from 267 companies listed on the Stockholm Stock Exchange A- and O-list in the year 2004. We find that the board structure has no significant effect on the CEO compensation.

This thesis examines the Swedish labour market with a focus on the immigrant part off the population. There are big differences between the immigrant and particular non-European immigrant part off the population and native Swedes. In the first part off this thesis I will show that immigrants in Sweden have a higher rate of unemployment, lower rate off employment, lower wage incomes, higher risk off unemployment and are overrepresented in low skilled, low status jobs. Even when controlling for different factors such as education level, knowledge in the Swedish language, age etc. a big gap remains.

Earlier quantitative entrepreneurial studies with a focus on poverty rate has centred their arguments and analyses entirely on income differences which has resulted in a high poverty rate among self-employed. Their results shows that variables such as age, gender, hours of labour and structure of the household significantly affect the poverty rate among self-employed. In this study we aim the focus on material living standards instead of income differences, thus using a more representative approach while studying entrepreneurial poverty. The purpose of the study was to examine how personality traits (big five) affect the material living standards among the self-employed in Sweden, using a group of employed as a control group. Variables earlier known to affect the poverty risk among self-employed where used as control variables together with education and household income.

This thesis investigates how inventory management is practiced at a Swedish sawmill company, how practice differs from theory in this field and how the company could make more use of this theory. To do this we have performed a study on relevant literature and compared our findings with a field study on Moelven Valåsen AB. Our analysis shows that a large gap between theory and practice exists. We identify several reasons to this, including some sector specific problems when calculating cost rate for timber inventories. Suggestions on solutions to these problems and an example of how a cost rate can be estimated with relatively simple means are presented.

Corporate governance intensified due to the corporate scandals in the USA which led to a new law the so called Sarbanes-Oxley Act (SOX).In 2005 the "Svensk kod för bolagsstyrning" (The Code) was introduced. The main purpose of The Code is to strengthen the confidence in Swedish companies quoted on the Stockholm Stock Exchange. The Code focuses on the working process of boards. The rules set by The Code places higher demands on the board.  Among many other duties the board has to establish long term operational goals and strategy.

In the past, the meaning of marriage has been an agreement between two people to live together and have children in a legitimate manner. The marriage was not just to form a couple; it was also to merge two families together. From the early 1900s until today the allegation of marriage and its influence got a significant change compared to early societies which have aroused my interest to perform this into a research paper. My study is focused on marriage and social changes during the 1900s. Thoughts that arise now is that why there was a remarkable change in the marriage rate during the 1900s and whether there were any social changes had to do something with it.

Title: [Frontline bureaucrats discretion in the transition to Establishment Reform]This essay aims to study discretion among frontline bureaucrats as an important factor in the integration of immigrants. In contrast to other studies of discretion this essays has its focus on a new establishment reform that has been recently legislated. The theoretical frame is based on the concept of frontline bureaucracy developed by M. Lipsky (2010). In the analysis of the discretion in this specific area I have been inspired by I.

Our digital society encompasses nowadays different channels, which includes social media where many users consider it as a platform where they can fetch news or exchange news and information. This leads to a large spread of news exchange in a very fast speed, which involves the global users within social media to be a part of this social interaction. This study is focused on how Twitter affects the usage of the user?s news consumption. By reaching out to our specific target audience, which includes Twitter users in Sweden, we made a web based survey with a content of relevant questions.

Purpose:Only 60 percent of the newly started companies survive their three first years. The purpose of this report is to obtain a deeper understanding regarding how newly started companies work with their positioning and if there are some kind of a relationship between positioning and the survival rate of newly started companies.Research questions:Do newly started companies know what position is? Do they incorporate positioning in their day to day marketing?Approach:We have used a hypothetical-deductive way of reasoning and a qualitative study to gather the information needed. We have through interviews asked our questions to six newly started companies in three different cities.Findings:In our essay, we reached the conclusion that newly started companies do not spend sufficient time or energy on positioning their products. The companies interviewed only market their product as a good product.

Uranium (U) is a naturally occurring component in bedrock and under the "right" conditions it can dissolve and move into the ground water. Since many people in Sweden depend on drilled wells as their main drinking water supply, they may be exposed to the uranium in the water. Radioactive radiation is not the major concern associated with naturally occurring uranium. It is rather the chemical properties of uranium that make it a potential danger to human health. Uranium is proven to have toxic effects with respect to the functioning of the kidneys.

In 1993 the internal market within the European Union was formed and ensured free movement of goods, services, capital and people. This led to the removal of trade barriers between members of the European Union. When opening up for competition, price differences between countries decreased and more jobs were created. A single currency was introduced by eleven countries in 1999 with the goal of reducing transaction costs, eliminating Exchange rate risk and to further simplify trade. In 2001 Greece joined the collaboration and introduced the euro.
