Hormonersättningsterapi (HRT) används för att lindra vasomotoriska och urogenitala symtom associerade med klimakteriet. Eftersom behandling med enbart östrogen förknippats med endometriell hyperplasi och livmodercancer, tillsätts progestagener till östrogen-beredningar i HRT hos kvinnor med intakt livmoder för att motverka den proliferativa effekten av östrogen och förebygga cancerutveckling i livmodern. Sådan kombinerad HRT har emellertid associerats med ökad risk för bröstcancer. Vid kombinerad HRT används olika typer av progestagener och olika behandlingsregimer (kontinuerlig eller sekventiell tillförsel).Syftet med detta arbete var att undersöka vad som ökar risken för bröstcancer vid kombinerad HRT: valet av progestagen-typ eller vilken behandlingsregim (kontinuerlig/sekventiell) som används.Metoden som användes var en litteraturstudie som omfattade sju studier om HRT och bröstcancerrisk, vilka hämtades från databasen PubMed.Utifrån undersökta studier kan man dra slutsats att ökad risk för bröstcancer associeras med kombinerad östrogen-progestagen HRT jämfört med HRT med enbart östrogen och framför allt om man jämför kontinuerlig kombinerad HRT med sekventiell kombinerad HRT med ett dos-responsförhållande som bakomliggande grund. Progestagen-typ kan ha effekt på risken för bröstcancer men detta behöver undersökas ytterligare..

This thesis examines the reasons behind the Swedish migration policy reform which led to a replacement of the Aliens Appeal Board by the Migration Court. This introduced a two-party procedure, oral hearings and enhanced transparency. It was designed to guarantee the rule of law and to thwart political arbitrariness.The transfer of power from representative institutions to judiciaries is referred to as judicialization, and the Migration Courts may be considered a typical example of this phenomenon. However, this can be questioned. The straggling nature of the term implies everything and anything unless cautiously defined.

In this investigation has an attempt to find out whether so called transplanting shock depends on the moving and transplanting of trees, to other conditions, or if it is due to the imbalance between the root to shoot ratio. Seventy trees of Prunus avium have been part of the investigation and these trees have been divided into four different groups depending on methods of production, untouched on the field, trees still on the field but with root pruning, trees moved and planted into Root-Control-Bag, trees moved and planted into Spring-rings. To be able to answer the question, measurements of the length of the terminal shoots and the lateral shoots and the dimension of the stem growth have been done and also has a visual judgment of the trees vitality been performed. The result shows that it is not only the move of the trees that gives them transplanting shock, but rather the loss of roots which gives an imbalance between the root and crown..

This study deals with the technical and economic feasibility of replacing the nuclear power plant reactor Ringhals 3 with a biofuel power plant. A technical investigation has been executed to determine which of the systems and components that could be reused and which ones would need to be replaced. The investment costs of the reconstruction have also been estimated. The cost of the electricity production has been calculated as well as the emissions of the new biofuel power plant. Based on the established rate of return, the lowest average spot price of electricity that makes the investment profitable has been calculated.

Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment. The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.

In southern Sweden, beech (Fagus silvatica) and spruce (Picea abies) are two species with similar demands on soil properties. With increased global warming and high acid deposition the future may bring larger areas were the two species are overlapping, competing for the same soil. The aim of this study was to compare spruce and beech concerning distribution, cultivation and soil properties. From available data comparisons were made between spruce and beech forests in Sweden. Soil analyses were made on samples from beech forest in southern Sweden, with and without natural regeneration of spruce.

This master thesis is a result of the work carried out for Research Electronics at Siljansnäs. The company develops customized electronical systems. Because of the rapidly increasing interest in colour displays there has been a desire within the company to represent information from sensors and electrical systems in a more advanced way.Due to the mentioned reason above we were given the assignment to solve how a colour display using the STN technique works. The technique is used by small displays, the size of QVGA. Our ambition of this diploma work is to develop a fully functionally test prototype to evaluate the LCD (Liquid Crystal Display) and the LCD controller.

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).

This report is a part of the process of enhanced cooperation between fire rescue services in the region of North West Scania. The aim of the report is to study and analyze how the fire rescue service should be structured, in terms of rescue units and personnel, if no account is to be taking to the current organization. Two types of accident are considered in the report, traffic accidents and building fires. These are more affected by decreased response time than other accidents. Several suggested organizations are presented and they are evaluated with the computer program REP.

The purpose of this bachelor degree thesis is to analyze technical issues associated with an implementation of a low sloping trash rack with narrow spacing. A hydropower plant in Umea?lven was used as a case study. The basis for the study was a model where trash racks were dimensioned for inclinations between 25 and 45 degrees. Corresponding head loss, durability and water speed through the rack were then determined for each inclination.

Purpose: The purpose of this study is to investigate how three banks country funds are performing relative to each other in regard to risk and return. And to find out if there is any underlying factor that may have affected the stock exchange in the different countries.Methodology: The study is based on secondary data and will apply the quantitative method, based on a deductive approach. The sample consists of three major Swedish banks and from them we have selected three country funds. The calculation formulas that have been applied are: Sharpe ratio, standard deviation and Arithmetic Average.Conclusion: The Writers concluded that Sweden funds had the highest yield to lowest risk in both periods in all three major banks. We have also concluded that the underlying factors affecting a country fund.

Aim: The aim of this study is to do a comparative study between Swedish Ethical equity Funds with Swedish traditional equity funds in terms of return, risk and risk-adjusted return.Theory: Sharpe ratio and Modigliani-Modigliani.Method: The essay will be based on a quantitative research method in which secondary data is the basis for the calculations. A statistical analysis was applied.Conclusion: The study concludes that there is no significant difference between the ethical fund group and the traditional fund group in terms of return, risk and risk-adjusted returns. The traditional fund group was those who had the best returns but only by small margins..

During our formative years, technology has always had a natural part of everyday life, and for us technology has never been particularly gendered. If this depends on the climate and the attitude of our homes, ourselves, the combination of both or something completely different is a question we have asked ourselves at times. But our approach to technology does not seem as obvious to all women, and today the IT industry is heavily dominated by men. This has meant that we have asked the question whether there is any underlying reason why so few women opt for IT courses? Is there a link between how different IT organizations profiles and the prevailing gender ratio? The purpose of this study is to investigate whether there is any connections between how IT organizations are related to gender issues and how the structures, attitudes and gender actually looks like in the IT industry today, and how this can be seen in their branding efforts.

Ribs from sheep, goat and pig are rarely assessed  to species due to the fact that they are very similar in their morphology and size. The ribs are instead considered unidentifiable although it is possible to see what kind of bone it is. If these ribs would be identified to species not only would species assessment degree of archaeological source material   increase, the relationship between meat-rich and meat poor regions would change.To find out whether there are morphologically measurable differences between sheep, goat and pig ribs, three measurement points on each rib has been defined and measured. At each measurement point two measurements were measured, one medial-lateral measurement and one cranial-caudal measurement. The ratio between the medial- lateral measurement and the cranial-caudal measurement was calculated for each point.

Syftet med uppsatsen är att belysa i vilken utsträckning valda faktorer påverkar direktavkastningen i Sverige samt att klargöra huruvida investerare kan använda faktorerna i syfte att uppnå önskad utdelningsnivå. Metoden som har använts är kvantitativt baserad, den empiriska datan är företrädesvis insamlad från databasen Six Trust, tillhandahållen av LINC vid Lunds Universitet. Angreppssättet har varit deduktivt, där teorier har testats genom multipel regressionStudien visar inte på något entydigt signifikant resultat för de undersökta variablernas förklaringsgrad på direktavkastningen. Resultatet motsäger därmed ett flertal erkända forskares tidigare resultat, däriblad kan nämnas John Lintner(1956) som menade att utdelningen i mycket stor utsträckning kan förklaras av företagens vinster, något vi inte finner stöd för. Vid prognosticering av utdelningsnivån hos svenska börsföretag bör undersökta variabler inte ligga till grund för placering..
