The guest harbor on Utö, Utö Gästhamn, is currently using electricity for heating all of the water used in the showers and taps. Because of the large amount of visitors, especially during the summer months, the hot water usage gets very high and that is also the case for the electrical bills. During the year of 2011 the cost of electricity for Utö Gästhamn reached a total of 257 500 kr. Out of these 257 500 kr approximately 142 000 kr, 55 % of the total cost, were because of the water heating.The report is the result of a cooperation with Skärgårdsstiftelsen, the Green Islands-project and Utö Gästhamn where the mutual goal is to dimension a solar energy system, to promote the sustainable development.Initially the different techniques for the solar energy system are researched. The techniques are plane solar collectors, evacuated tube collectors, pool collectors and photovoltaic cells.

Parenting and parental leave in a career context is a highly topical subject in which discussions about gender equality and corporate discrimination against parents occur daily. Media has recently raised the theory of parenting and parental leave as having positive impacts on personal development, such as creativity enhancement, which may promote the individual's work performance. Despite the subject's significant value for society and organizations, no scientific research is to be found. This paper examines how an individual's creativity at work is affected when becoming a parent and if parental leave has any contributory effect. Furthermore, the paper identifies and scrutinizes four creativity theories that may help explain these changes in creativity.

Background:Investments in different forms have always been popular to every human being. For the most common investments, such as stocks and bonds, there are loads of information to gather for the investor. Historical data like risk, return, dividends and fundamental data like annual reports are often very easy to find, regarding these kinds of investments. The background of this thesis is the lack of market information in residential real estate investments. A problem with this investment is that there is lack of information regarding risk adjusted return for real estates, which this thesis intends to present.Objective:The objective with this thesis is to study which alternative, directly-owned residential estates or stocks, who generates the highest risk adjusted return.

I have worked with Bergum in different courses on the IntegratedConservation of Built Environments program and I thought it was a veryinteresting subject. This is the main reason why I chosen to write mybachelor paper about Bergum.In 1650s Bergum was situated on the border between Sweden and Norway,because of that it occurred some war conflicts.Today Bergum is a socioeconomic border and is situated in an areabetween the city?s concrete suburb and the countryside.The difference between the city?s concrete suburb and the countryside mayfeel like two different worlds, were the social contact is fractional.With this paper, I will indicate a countryside area on the boundary to the citythrough time and try to survey the building history. I will also try todemonstrate the socioeconomic differences between the areas.I will demonstrate Bergum history from prehistory to present time, were I willdiscuss the agriculture history, Vättlefjäll?s forest history and also thedeforestation and replanting.

Magnesium is an essential mineral that is important for several physiologic and biochemical processes in the body. Deficiency of magnesium is mainly associated with grass tetany, but can also appear in cows during the indoor period. Since long it is known that potassium has a negative effect on the absorption of magnesium. Due to the fact that potassium fertilisation leads to a higher potassium content in forage, it is of interest to study interactions of potassium on the magnesium balance in dairy cows. There are few studies about magnesium feeding to dairy cows in Sweden and the purpose of this study was to investigate how much magnesium and from which feed-sources dairy cows in Sweden get their magnesium. Data was collected from seven farms in the northern part of Uppland and from seven farms in Skaraborg in Sweden.

Vi har i denna uppsats haft som syfte att studera butikssäljare och hur de agerar i sin yrkesroll. Fokus i denna uppsats ligger på hur butikssäljarna själva upplever sin yrkesroll och de uppgifter som följer med den. Då vi har utfört denna studie utifrån en deduktiv ansats har vi använt oss av Erving Goffmans rollteorier som teoretiska antaganden. Studien har utförts utifrån en kvalitativ ansats och vi har till denna undersökning gjort ett strategiskt urval om sex informanter som alla jobbar i olika butiker. Dessa informanter har vi sedan utfört kvalitativa intervjuer med.

Syfte, hypoteser och frågeställning:Syftet med studien är att undersöka hur kostsammansättning påverkar prestation, upplevelse och fysiologiska parametrar hos unga män, i samband med högintensiv fysisk aktivitet. H1 Fysisk prestation, här definierat som total producerad energi under testtiden (J),maximal kraftutveckling (W) samt ett medelvärde på kraftutveckling (W), på högintensitet är lägre efter intag enligt LCHF-kost jämfört med SNR.H2 Upplevd ansträngning under fysisk prestation skattas högre vid LCHF-kost jämfört medSNR.H3 RER (Respiratory Exchange Ratio) är lägre vid LCHF-kost jämfört med SNR.H4 Laktatnivån i blodet är lägre vid LCHF-kost jämfört med SNR.F Hur påverkas sinnesstämningen av en kosthållning enligt LCHF jämför med SNR?Metod:En experimentell crossover-studie utfördes på nio friska, träningsvana män i åldern 22-25 år. Samtliga deltagare genomgick en kostintervention under två femdagars-perioder på kosthållning enligt LCHF och Svenska Näringsrekommendationer (SNR), separerade med en nio dagars washout-period. Efter respektive kostperiod utfördes tester bestående av RER- mätning på ergometercykel samt upprepade Wingate-test (2 st) då de fick skatta upplevd ansträngning enligt CR100-skalan. I samband med testerna mättes även vikt, fettprocent och laktatvärden.

The paper, with a brief summary of timber floating in Sweden and also of some previous re-search in this field, contains a study on costs for timber-floating in the river Dalälven located in central Sweden. The public used timber-floating system in Dalälven and the historical background about this activity is described. The study is focused on the total costs for timber-floating in the public open floating system in Dalälven from 1900 to 1970, the year before the timber-floating was definitively closed down. Also the costs for separating the logs of a specific owner when they reached the point where they could be separated from the timber of other owners are analyzed..

This thesis describes the redesign ofequipment designed for drying bags thatis used in Fresenius Kabis´manufacturing of their nutritionmedicine in Uppsala. The need of thistask arise during the start of thedevelopment of a new packaging line werethis equipment were meant to be used. Anevaluation of the bagdryers capacity andcapability was necessary.The work started with gathering ofinformation from suppliers of the usedcomponents and from the responsibleengineers for this equipment. Aneducation to learn how the equipmentworked and how to operate it were taken.That was followed by the creation of astudy plan were the tests were plannedto test different parameters effect onthe drying result and to see if thebagdryer managed to handle the bags ofthe correct format in the pace that theequipment should be designed for.The test results detected a need ofdesigning a unit with a function thatholds the bags in place while passingthrough the dryer in order to attainhigh quality results. The results werelater used for optimization of thedesign.

The aim of this study was to understand the everyday mobility of families who are involuntarily carless and the practical consequences that arise when the private car is not an available alternative. Previous research shows that the involuntarily carless, as opposed to the voluntarily carfree, generally have lower income and fewer mobility options. This, in turn, affects the available strategies for organising everyday life. Using qualitative interviews, guided by thematic analysis, this study explores how carless families organise their daily lives and what strategies they use to make everyday life work.The results show that these carless families use a variety of transport modes, though the degree to which they use different transport options is highly situational, depending upon the length and distance of the trip, along with material and monetary means. Multiple interviewees recount that they lack the financial resources necessary to use carpooling options, to pay for public transport, or to buy bicycles for the family.

In this report a new gear concept is evaluated using the magnetic finite element method (FEM)software MagNet and Ansys as well as the mechanical FEM software Abaqus. The gear conceptis evaluated in terms of maximum torque capability, torsional stiffness, gear ratio and efficiency.ABB Corporate Research has proposed a new gear concept which should be less expensive thangearboxes used today. The new concept is called aMagnetic Harmonic Traction Drive and usesthe principles of a harmonic drive gear to achieve a high reduction ratio. The gear conceptreplaces the wave generator used in traditional harmonic drives with magnets and uses tractioninstead of gear teeth to transfer the torque. The main components in the gearbox are the magnets,the flexspline, the magnetic portion and the circular spline.

Researchers, planners, and government agencies agree that road safety for children must be a priority and in particular that children should have a safe and secure way to travel to and from school regardless of age or the distance travelled. In Sweden, child traffic safety is a key part of the country?s Nollvision, a long-term traffic policy goal of ?no deaths or serious injuries?. Unfortunately, many countries have recorded increases in child traffic accidents as the percentage of parents who drive their children to school and thus congestion around schools has increased. Common strategies include traffic safety education for children, the redesign and improvement of traffic infrastructure, bicycle training, and carpooling.This thesis assesses the traffic problem around Ludvigsberg School in the district Valbo in Gävle, Sweden.

The mining industry, in terms of ore excavation and metal production, is and has been important to the Swedish economy. In connection with the ore excavation process, large amounts of partly sulphidic waste are produced. When the metal sulphides are exposed to air and water they are eventually oxidised, which leads to the formation of acidic water with high concentrations of metal cations and sulphate ions, so called Acid Mine Drainage (AMD). This water may reach the nearest surroundings and cause negative environmental effects. By covering the waste with soil or water, the oxidation process can be minimised. At the Rävlidmyran mine in the county of Västerbotten open pit mining took place between 1951 and 1991.

During the 1970?s the interest for quality management and the concept of quality costs increased considerably. Business leaders noticed that there was a great potential for reducing costs of poor quality. Since up to 10-30% of a company?s total turnover may consist of poor quality costs some consider them as an unexploited goldmine.
