In a time when economic crises relieving one another, it is especially interesting to study how companies choose to finance their operations. Since there is a lack of studies that include banks, and their capital structures, with the rest of the finance market, it is uncertain whether the theories of capital structure are applicable. Therefore, this essay aims to study whether there is any Correlation between the two variables debt-equity ratio and return on equity (ROE) for Swedish corporations on the finance market.In accordance with the theorems that the professors Modigliani and Miller filed, in 1958 and 1961, which describes a clear link between debts, increase corporate value through the tax shield and indirectly increased yields. Although these theorems are the foundation of the modern research they focus on perfect markets. Therefore, this paper has also chosen to place great emphasis on theories such as Trade-off and Pecking-order.

Introduction: A complex interaction between muscles, tendons, bones, joints and nerves are required for optimal function of the human hand. It is known that an individual?s grip strength is vital for performance of physical demanding tasks such as strength training with free weights. Strength training including a thicker grip around the bar may enhance the strength of the grip in the athlete without other special routines for grip strength development. The purpose of this investigation was to examine the difference in performance in multiple repetitions in two strength training exercises using two different sizes on the bar, to look for Correlations between grip strength of the subjects hand and the amount of repetitions executed with two different size of the bar and finally the Correlation of hand size and the amount of repetitions executed with two different size of the bar.Method: 15 strength training men (23,9 ± 4,1 years), underwent measurements of hand size, maximum grip strength, 1 repetition maximum (1RM), a 80 % of 1RM weight strength test with two different  bar sizes.Results: The results from the present investigation indicates a 21,1 % reduction of 80 % of 1 RM weight performance in repetitions executed in the bench press with the thicker diameter of the bar and a 66,2 % reduction in repetitions executed with a 80 % of 1 RM weight in the lying bench row with the thicker diameter of the bar.

ABSTRACTSince Robert D. Putnam first wrote about the causes behind the regional differences in economic and political development in Italy, the theory of social capital has truly flourished in the fields of social science. This days you constantly hear politicians and scholars stressing the important role of the quality of the social fabric to a society?s wellbeing. There all looking at ways to construct policies and institutions that help the spread of social capital.

Vildbiet guldsandbi (Andrena marginata F.) har en central roll i jordbrukslandkapet som en viktig pollinatör av grödor och vilda växter. I Sverige hotas artens fortlevnad av biotopförlust, habitatfragmentering och födobrist. En av de viktigaste näringskällorna är växten ängsvädd (Succisa pratensis M.) som tidigare var vanligt förekommande men som nu minskar i sin utbredning. Syftet med denna studie var att utreda om populationsstorlekarna av guldsandbi och ängsvädd är relaterade. Guldsandbinas observationsbaserad populationsstorlek uppskattades samt att ängsväddens bestånd inventerades vid fyra lokaler i Övre Klarälvsdalen, i norra Värmland.

This essay sets out to compare political participation in two e-petition systems: The Malmö initiative in Malmö, Sweden, and Better Reykjavik in Reykjavik, Iceland. The main question of the essay concerns the aggregative and deliberative qualities of the Malmö initiative and Better Reykjavik, as well as the relationship between aggregation and deliberation. This main question is divided into four subqueries that lead the empirical analysis. These are: (1) Which similarities and differences in terms of design are there between the Malmö initiative and Better Reykjavik? (2) To what extent have these systems mobilized an aggregative political participation? (3) What similarities and differences are there concerning aspects of deliberation? and (4) What is the Correlation between aggregation and deliberation like in the two e-petition systems?The method in use is a comparative cross-sectional study with a 'most similar research design'.

The scope of this project is to make a comparison of costs associated with wind and nuclear power in order to decide which one of these is the most suitable in the case of an increased demand for electricity. It is also investigated if there are other factors that can influence the choice of energy source.An average cost is calculated in terms of kronor per kilowatt-hour (SEK/kWh) using cost of investment, operation & maintenance and taxes & subsidies. Total investment cost is recalculated to production cost using the annuity method at three different interest rates (6%, 9% and 12%).The comparison is made between three cases of wind power and two cases of nuclear power. For wind power there are two ocean-based (300MW and 100MW installed capacity, respectively) and one land-based (60MW) wind farm. For nuclear power there is one EPR-reactor (1600MW) and one AP1000-reactor (1100MW).

Lichens are adapted to bright and sparse forests on oligotrophic ground. Due to a slow growth rate and high light demand lichens will suffer from competition in eutrophic environments. Therefore, lichens have disappeared from managed forests where the forest industry has increased the productivity. A reduced abundance of lichens will affect both biodiversity of the forest and the reindeer winter graze lands. It is important to understand how and for how long fertilization affects the abundance and diversity of lichens in order to protect lichen rich ecosystems. We have registered the biomass and number of lichen species in eight plots (four nitrogen rich and four nitrogen deficient) and compared fertilized Sami settlements with their oligotrophic surroundings in the nature reserves of Tjeggelvas.

Common species of freshwater mussels may, like the freshwater pearl mussel (Margaritifera margaritifera) have a drastic decline in number and there is several reasons, like sedimentation, a decline of host fishes, introduction of alien species, nutrition leakages from agriculture and pollutants of medic drugs and poison. Ann Gustavsson made in the year of 2007 a study over rejuventation of freshwater great mussels in nine watersystems and considered that the rejuventation within the populations were all along the line poor. This study orients from her work and points to determine if there is a connection between the poor juventation and pollution of nitrogen and phosphorous from industries and private sanitations. The study was performed with the software program ArcGIS9.2 to take out drainage areas for the concerned habitats and contact was made with the concerned authoritys. When it comes to supervision of private sanitations is it the countys and for industries is it the county administrative board.

About 1000 women in the so called developing countries die every day associated with pregnancy and childbirth. Sub-Saharan Africa is the worst affected region. This study aims to explore the different key factors in national development that can interact with a reduced maternal mortality. The study compares 15 countries in sub-Sahara where the greatest reduction in maternal mortality occurred with 15 countries in sub-Sahara where maternal mortality reduction has been at its lowest, between the years 2000 to 2010. This study also analyzes the link between reduced maternal mortality and various key factors for national development.

ABSTRACTBackground: After general anesthesia the cognitive ability is temporarily impaired. Cognitive recovery is necessary for the patient to be able to assimilate the information that she / he gets postoperatively. It also increases the patient safety. There are few methods to estimate and assess the patient's cognitive recovery before and after anesthesia. The purpose of this study is to test the usefulness of the instrument PQRS and to assess the patients cognitive recovery after anesthesia.

Facilitated by the breakthrough of the internet, new ways of organizing internet-based projects that harness the power of the crowds are becoming increasingly common. Today there are ways of using the crowd as paid labour, as funders of your new project ventures and even for helping scientists doing science. Staying true to its traditional principles of objectivity and trustworthiness while asking the crowd to contribute, crowd generated ?Citizen Science? does not provide even the slightest amount of pay in exchange for the time and effort put in by their contributors. Surely there can not be many people willing to do such a thing voluntarily? Actually, practice is showing the exact opposite with contributions counted in their millions among the more popular Citizen Science projects.

The purpose of this study has been to create a better understading of how face?to?face activities in course´s impacts on the experience of interaction within a course.More specifically, the study puts the student'?s perception of how mandatory face?to?face activities affect and are affected by the interaction in focus. This is done by the following research questions. What affects the student'?s perception of face?to?face activities? Which interaction dimension affects the factors that influence students perception of the activities? Which interaction dimension is influenced by the student'?s perception of the activities?The theoretical base is Wagner'?s (1994) three types of interaction and Andersson´s(2003) theory of interaction dimensions.

Syfte: Studiens syfte är att analysera och undersöka om det finns något samband mellan den finansiella risken och lönsamheten. Det övergripande syftet är att se om valet av finansiell risk fungerar som finansieringsstrategi i verkligheten.Metod: Studien bygger på den deduktiva ansatsen där teorier kommer att testas och analyseras mot empiriska data tagna från årsredovisningar. Den kvantitativa metoden används då data från 305 stycken årsredovisningar ska användas för att finna om det finns samband och variation mellan finansiell risk och lönsamhet definierad som vinstmarginal, Rt och Re. Årsredovisningarna utgörs av sekundärdata som samlats in från databasen Retriever. De statistiska metoder som används är bland annat medelvärde, standardavvikelse, regressions- och korrelationsanalys, hypotesprövning och t-test.Resultat och slutsats: Såväl korrelation- och regressionsanalys som hypotesprövning och t-test visar att det finns samband mellan finansiell risk och lönsamhet definierad som Re.

Headwater streams are affected by anthropogenic impacts at multiple scales. One aspect of human impact is sediment transport associated to the abundance of stream structures as large woody debris and the composition of the riparian zone from forest to agricultural landscapes. Riparian buffer zones and stream structures like dead wood are considered as generally important structures for protection against an increasing amount of sediment particles in the water. Hence, in this study these structures were quantified in thirty different stream segments on land and in the water. To measure the transport of sediment Whitlock-Vibert boxes were used in three different types of landscapes; forest, transition and fields. The boxes were left in the stream segments for three months, the taken up and dried and weighed. The results showed that the transition-land in Frösvidalsån had the highest sediment transport. The second highest transport of sediment was in Blackstaån at the fields.

The objective of this work was to evaluate and compare three field methods for detection of mastitis, California Mastits Test (CMT), DeLaval cell counter DCC (DCC) and FMA2001 Farm Milk Analyzer (FMA2001). Furthermore, to investigate at what cell count level clinical symptoms of mastitis are seen, and finally to check if the clinical findings and cell counts could be related to bacteriological findings. DCC and FMA2001 are new analytic instruments to be used on dairy farms for detection of mastitis. CMT has been a widely used cow-side-test of milk quality in mastitis control efforts, but it cannot be used for estimating cell counts in scientific studies or investigations. Two hundred and eight quarter milk samples from 52 cows were analysed with DCC and CMT, and 168 of these samples with FMA2001. Microbiological examination was done on 38 milk samples with CMT scores of 4 and 5.
