In couples diagnosed with unexplained infertility, the woman has normal ovulatory cycles and no organic pathology, and the man has normal semen. The period during which the implantation of an embryo can occur is defined as the window of implantation (WOI). For infertile women, disturbances in the endometrium maturation are hypothesized to impair the uterine receptivity for embryo implantaition. However, there are still no methods found to predict endometrial receptivity.Hemoglobin related-proteins hypothesized to be involved in embryo implantation have been found in the endometrium in both fertile and infertile women. The aim of this study was to determine whether there were differences in the expression of hemoglobin-related proteins, hemoglobin-?, cytoglobin, fetal hemoglobin and haptoglobin in the endometrium of fertile and infertile women.

The dry out criterion (MCPR) has been calculated for the most limiting H2-events for Forsmarks unit 2 and 3, at operating points that are normally not analyzed before each cycle. The operating points that normally are regarded as the ones with the lowest margin to dry out are the ones where the thermal power is the highest at agiven recirculation flow. This report shows that this is not the case for Forsmark 3. MCPR-values at partial power operating points are higher for the limiting case inside rather than on the boundary of the region of operation. It is therefore recommended that the method for determining the dry out criterion for Forsmark 3 is revised to account for this effect.

The City of Stockholm has decided to invest in renewable energy and especially in photovoltaics. The objective of this thesis is to investigate the photovoltaic potential on roof areas that the city possesses and to further investigate some buildings of the Property Management Department. The thesis also compares some existing photovoltaic plants with the solar irradiance map which shows available roof area on each building in Stockholm. The report ends with a literature study about the climate impact and greenhouse gas emissions of photovoltaic.The total available roof area suitable for photovoltaic plants is estimated to 700 000 m2, with a potential electricity production of 110 GWh per year. This corresponds to 17 % of the City of Stockholm?s yearly electricity consumption.

Practitioners of financial statement analysis are dependent on key ratios in a multiple number of situations, one in particular being equity valuation. A lack of historical benchmarks, and knowledge regarding the time series behaviour of such ratios, has been identified regarding Swedish companies. Therefore, this study sets out to provide such data and knowledge. Companies listed on the Stockholm Stock Exchange are examined over the period 1979-2009 where the sample is divided into nine industry groups. Historical values for eight common key ratios are documented with regards to median, mean, standard deviation and percentiles.

Sustainable beef and milk consumption. The consumption of beef and dairy products in Sweden is high. A lot of greenhouse gases are emitted from the production of these products. The production of beef in Sweden has decreased but the import has increased. The number of dairy cows has decreased while beef-production with suckler-cows has increased in Sweden.

Den här rapporten behandlar frågeställningen om hur man kan anpassa systemutvecklingav ett informationssystem enligt livscykelmodellen till att inkludera användbarhetstester. Frågeställningen grundar sig i att god användbarhet inte är ett explicit uttryckt mål i Andersens beskrivning av livscykelmodellen. För att besvara frågeställningen har vi utvecklat och testat ett bokningssystem åt en mindre verksamhet. Utvecklingsarbetet har bedrivits enligt en egen anpassning av livscykelmodellen. Testerna har utförts enligt metoden cooperativ evaluation.

The purpose of this master thesis is to investigate different types of measures for making buildings more energy efficient and to estimate their profitability. The calculations were performed with the building simulation program VIP+ and the evaluation of the profitability with the life cycle cost method. Furthermore, it was examined how losses in the distribution of secondary systems of district heating can be avoided. Options to replace district heating with a local district heating system based on bio-energy have been investigated. The possibilities of achieving more efficient thermal energy consumption and production for the chosen estate were also examined.The object of the study has been a residential estate with 133 detached houses in Uppsala, built in 1974.

The purpose of the study is to examine and analyze the relation between the existence of global companies and given support to immigrant- owned companies with large cultural difference from public services. This helps answering the question "Which affect does the existence of local dominating companies have on the establishment of small companies owned by immigrants with large cultural differences?" This has been accomplished through a field study containing twelve interviews with small companies in two different cities and two interviews with the community officials in each city. The research was thereby narrowed to only treat the two cities in Sweden in order to examine the relation between public services support to small immigrant-owned companies and how the immigrants experience the support from them. The analyze was made due to a handful of theories such as the The network theory IP model, Hofstede's 4+1 model and the Product Life Cycle.

AbstractThis degree thesis was made in cooperation with Chematur Engineering in Karlskoga.Many of the environmental issues of today are a result of the motor traffic. Consumption of fossil fuels harms our environmental through formation of carbon dioxide and other greenhouse gases. To get under control with our environmental issues it?s important to find substitutes for oil that are both cheap and environmentally friendly. Ethanol has a long history as a motor fuel and is both enviromentally friendly has a high efficiency.According to the EU commissions directives for motor fuels, 5, 75 % of all the fuels in Sweden should be renewable in 2010.

The Swedish business cycle is in a strong position at the moment, leading to great results and larger profits. This strong business posture has encouraged companies to increase both their liquidity and revenue. Now there is a dilemma, what actions should or could a respectable business take on these newfound liquid assets.The purpose of this paper is to deliver a clear picture of what options there are for such companies listed on the Swedish stock-market, and how the market wants them to act. To these means we have studied the basic theories linked to this subject and reviewed the cause and effects that motivates them. We have also conducted interviews with the people representing the market through their line of business.In the theory we found several options on what companies in similar situations tend to do.

This thesis evaluates the environmental performance of six different fish farming systems. The thesis is part of the network group ?Hållbar fiskförsörjning I Stockholms län? (HFFS) which tries to increase the domestic and regional production of fish in Stockholm and move to a more sustainable supply in the Stockholm county. Two of the chosen systems; pangasius from Vietnam and salmon from Norway are delivering a substantial part of the fish consumed in Stockholm today, although they are very different when it comes to system characteristics. One system, arctic char with conventional feed, is produced in a fairly small scale in the north of Sweden, while the three remaining systems are viewed upon as possible options to supply Stockholm with fish in the future.

FDI har sedan början på 80-talet växt sig allt större och blivit en av de viktigaste tillgångarna till finansiellt och fysiskt kapital i världen. FDI har enligt många studier en viktig funktion för ett lands ekonomiska utveckling, detta gäller främst för outvecklade länder men också utvecklade länder. Studiens mål var att hitta viktiga faktorer som påverkade FDI inflöde till Sub-Sahara regionen. Den empiriska analysen gjordes med hjälp av en OLS regressionsmodell och hade 42 observationer sammanlagt. Huvudvariabeln var FDI/BNP.

The environmental debate is more intensive than ever before and the demands on companies increase. There are a number of methods to make it easier for the companies to fulfil the demands. Life Cycle Assessment (LCA) end ecodesign are some of the methods that can be used. Syntronic AB has the possibility to reduce the products´ environmental impact in the design phase. Therefore it is important for the company to make it possible to visualize the negative environmental impacts a product can cause in an easy way. It is also important to visualize for there clients if any improvement is possible. The purpose of this thesis is to develop a simplified model.

This study investigates whether the permanent measurement bias (PMB) has changed over time for Swedish companies listed on the Stockholm Stock exchange at least one year during 1996-2000 or 2005-2010. By using the Residual Income Valuation-model the markets' implicit value on PMB is generated through reversed engineering, as values for all variables except PMB are entered such as the market perceived them at the specific valuation date each year. This implicit value is classified into industries and then sorted by their median. Statistical tests are performed to see if there is a difference between the industry median and the accounting-based values on PMB. The difference from period one to period two is also statistically tested for.The study finds that the implicit values on PMB have changed somewhat between the periods; however the fluctuations are not statistically significant.
