The goal of this thesis is to design an attachment between a duct and a pod. A pod is what could be compared to an outboard engine for larger vessels. The pod is placed on the outside of the ship?s hull and can rotate 360 ?. A duct is a large steel ring that can be placed around the propeller on the pod to increasethe propulsion force of the ship in lower velocities.

Forest as an investment alternative has become more and more popular over the last few years. Between the years 2004 and 2007 increased the price level on forest land with 70 percent in Jämtland. In this thesis a comparison has been conducted between forest in Jämtland and an investment in the stock market. The risk in the two investment alternatives has been included in the comparison. The thesis includes two different studies between the two alternatives.

Det har börjat bli allt vanligare att organisationer ser över sina traditionella intranät och börjar titta på möjligheterna med sociala intranät (Ward, 2012). I den här uppsatsen presenteras en definition av ett socialt intranät och hur det främjar informationsdeltagande och socialt nätverkande. Genom att utföra en fallstudie på Medarbetarportalen på Uppsala universitet har det framkommit att det finns ett antal hinder som har en negativ effekt på införandet. Vi anser att en utförlig behovsanalys, där man inte haft överseende med någon organisatorisk eller informell grupp där samtliga intressenter är medvetna om vilka fördelar som finns med sociala intranät, är nödvändigt för lyckat ett projektet..

The purpose of this study was to investigate the presence of arterial insufficiency in patients undergoing CABG surgery and whether arterial insufficiency is a risk factor for postoperative wound infections in the harvesting leg. Patients who had CABG surgery were enrolled consecutively. A total of 144 patients participated in the study. During their hospital stay demographic data was recorded, as well as pre-, intra-, and postoperative tests and risk factors. The patients answered a questionnaire regarding postoperative wound infections 30 days after surgery patients answered a questionnaire regarding infections.

A growing population together with a change in food habits to a more diverse diet containing more animal products such as meat and milk makes the possibility to produce and sell products of cattle a growing market. And at the same time there is an ongoing debate about global warming, where raising cattle is questioned due to their high production of enteric methane. To be able to raise animals in a more environmental friendly way and at the same time improve productivity in a developing country such as Vietnam would be favorable. The use of feed additives with high electron affinity could decrease the methane production and at the same time improve the gross energy digested. Nitrate and Sulfur are both good electron acceptors, but due to its toxic effects the use of nitrate in feed has been neglected.

The aim of these two studies was to investigate the possible physiological, behavioural and emotional changes that appear after human-horse interactions and also to find an explanation to why they occur. One aspect that is discussed is whether the wellbeing of humans can be coupled to interacting with horses and of how the animals respond to the interaction. The first study was performed on 9 horses and their owners, both parts being subjects to registrations during 4 different interaction treatments. The second study was performed on 6 horses with registrations only being performed on the horses during 2 different treatments. Nine horses underwent 3 different treatments all performed by their owners (H = stroking of the horses forehead, B = brushing and M = stimulation of the withers) in addition to a control round (K). Each treatment lasted for 4 minutes but observations were performed until after 45 minutes from start.

The purpose with this study is to compare different systems of grain storage from a financial point of view. Grain that is supposed to be fed to laying hens. The systems that were compared were different airtight storage of grain and a system of conventional storage. To make this case study I choose to compare four different systems. In the case study there was one system with bin drying of the grain, two systems with airtight storage of the grain and one system where you buy dried grain during the season. I made several of capital investment appraisal where I found the cost of each system, then I took the cost and divided it with the total grain use and calculated the cost for each kilogram of grain, and also the cost of the feed. Then I compared the cost from my case study with the cost of buying feed. All the systems except for one, gave a lower cost for the hen feed than buying feed from a dealer The best system, witch were bin drying lower the cost with about 80 000:- SEK.

Dairy cows transform grass to milk with help from ruminal microorganisms that can digest indigestible fiber in their feed. The digestive system of the cow is adapted to a diet consisting of forage and disorders like acidosis, laminitis and abomasal displacement can occur if the feed contains too much starch. To achieve the highest production possible the cow has to be given a high amount of concentrate or grain as the difference in milk yield is significant, approximately 1000 kg energy corrected milk per cow and year between conventional and organic cows that are fed a lower versus a higher share of forage. If the cow shall be able to eat the same amount of energy from forage as from grain or concentrate the eating- and rumination time gets longer and she might not be able to eat enough, which will result in a lower milk yield and will make it harder for the cow to recover from the negative energy balance that originate from the beginning of the lactation. Fat and in a sense protein content differs also depending on if the cow is given a high or low share of forage..

How do gender and socioeconomic backgrounds affect students? academic performance, educational choices and attitudes towards education? Moreover, does class play the same role for girls and boys? In order to find this out, I surveyed students in a small province located in the northern inlands of Sweden. The survey was answered by nearly every student in the ninth grade of that year, a total of 160 people. The results revealed that girls in this area have less faith in their capabilities than boys, despite getting much better grades. Many more girls than boys want to go onto college or university studies.

The study focuses on the use of poetry in language teaching in the lower grades in the Swedish school. Poetry has a reputation of being an art form with such specific rules and structures that children and teachers think that it is something that they do not have the ability to work with.  The purpose of this study is to get an understanding of how poetry is used in educating children. My research is based on the following questions. To which extent is poetry being used in schools and how is it being used?Can you as a teacher see any effects on childrens language development by using poetry?As a part of my study I have met with and interviewed four different people, who in one way or another is involved in teaching children. Two working teachers in the lower grades, one pedagogical resource and one artist that work with teachers in reaching different goals through the help of aesthetic processes.

The purpose of this thesis is to investigate whether the lower secondary school teaching in religion leads to a positive understanding and openness, concerning different religions and cultures. We want to study how pupils in grade eight and nine in two lower secondary schools in a multicultural community comprehend different religions. Since we choose a pupils perspective we decided to do a questionnaire to get a wide ground. As a complement we interviewed twelve pupils and also did observations during their religion classes. During our study we focused on three different themes.

 This paper evaluates the effect of exchange rate risk on the sum of bilateral trade. To distinguish the effect between different types of countries, two groups are defined: advanced and developing economies. Economic theory on exchange rate risk and trade proposes ambiguous effects of increased volatility. However, the ex ante hypothesis is that developing economies are more sensitive to volatility. Contrarily to the hypothesis, the empirical results suggest that advanced economies would benefit up to twice as much from a removal of exchange rate risk.

With the ambitions to rehabilitate individuals with different kinds of work disabilities through work, the government owned Samhall AB has a long history as labour market measure in Sweden.To show Samhall AB its importance, the company has requirements to fulfill the goal that around 5 percent of their employees, at Samhall AB, every year shall be transferred to an employment outside the company, which is called transition. Unfortunately since this goal was introduced it also created several dilemmas. One dilemma is the long lasting female under representation in transitions from Samhall AB to the regular labour market.The essays main task is to investigate the factors behind the female under presentation in transition from Samhall AB through a genus perspective and by using quantitative and qualitative method.The main conclusions are that female under representation in transitions from Samhall AB are basically caused by structural factors. Samhall AB?s strong industrial tradition and particularly the strong segregation between female and males on the regular Swedish labour market may inhibit females in their transitions.

Glycogen is the storage form of glucose and is used by the skeletal musculature as energy both for intense and endurance events. The glycogen content in the horse?s middle gluteal muscle is more than 600 mmol/kg dry weight, and almost 400 mmol/kg dry weight in the human?s Vastus lateralis. In some special occasions, for example in competitions with several moments on following days, there is a need of a fast muscle glycogen resynthesis. The feed intake is of importance for the velocity of the resynthesis.

The aim of the current study was to examine the radical right-wing sympathizers in Sweden. To fulfill this aim, a quantitative case study on Sweden Democrats sympathizers was conducted. More specifically, this study has examined socio-economic backgrounds and political attitudes of the Sweden Democrat sympathizers. The results show that sympathizers of Sweden Democrats are higher among younger people and men. The results also show a higher support for Sweden Democrats among people with lower education and low income that also live in small towns and in the countryside.
