This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.

Contemporary plant design can be examined by how it relates to two extremes - Nature and Art. This idea is explained by Noel Kingsbury in the book The Dynamic Landscape where he places designers and their projects on a gradient (Kingsbury, 2004). Nature, one of the extremes can be represented by a dynamic, species-rich plant design with native species and with nature as the ideal. The other extreme - Art implies a more static view on plant design. Here, the designs consist of colourful flowers, exotic species and cultivars with double flowers.

The modern veterinarian in horse practice is often consulted by horse owners concerning riding problems. These problems are more complex and show other characteristics than traditional lameness. For the diagnostic process and to give adequate advice the veterinarians need an understanding of riding terminology and problems related to riding. It is also of high importance that riders, trainers and veterinarians increase the knowledge of equine biomechanics and how these are influenced by the rider. Collection is an important concept in the riding terminology.

AbstractThe purpose of project is to study the possibility for Borås Energy & Environment to build and run a commercial ethanol production facility in Borås. The project also studies the technology for the production of ethanol using renewable energy, e.g. lignocelluloses with focus on two processes, svag-syra hydrolyse and enzymatic hydrolyse. The technology of the process is based of hydrolysation of biomass (hemicelluloses and cellulose) to sugar and extract it to ethanol. These two techniques will compare with each other to determine which of them that it?s more suitable for ethanol production.

Title: The key to the positive spiral - A study of musicians views of their practicing. The purpose with this paper is to make clear how continuous practicing on one element affects not just the specific part but also other things. Is it possible to find a positive spiral where everything can be better if you focus your practicing on one thing? Can this element if it is done daily in a qualitative way transform to a key which will help you to unlock the door to the positive spiral? Are there more keys to find? I am going to reflect my ideas in this paper through a philosophical, psychological and the brain sciences perspective. Quality in action is going to be compared with the quality that you need to set a successful goal, and to reach the state of mind called flow you will need both these qualities.

Umeå Energi AB har bestämt att en kontroll av pannverkningsgraden för kraftvärmepannan Dåva 2 skall genomföras. I dagsläget genomförs en beräkning av verkningsgraden månadsvis med den direkta beräkningsmetoden. Resultatet varierar dock kraftigt månad till månad varav en undersökning med indirekt beräkningsmetod är av intresse. Arbetet genomförs för att ge en mer noggrant beräknad verkningsgrad samt utreda förlustfaktorer kopplad till pannan. Då pannverkningsgraden i vanliga fall inte inkluderar rökgaskondensering beräknades också totalverkningsgraden för att ge en mer rättvis bild av pannan samt för att illustrera dess relevans.

Interest deduction limitation rules have an important function as the regulations prevent the Swedish tax base to decrease. However, the restrictions must not be at the expense of the business environment. Interest deduction limitation rules that do not work in a satisfactory manner are likely to make Sweden a less favourable country to establish in. The first Swedish rules which were aimed to restrict interest deduction threaded into force in 2009. The rules were applicable to intercompany loans related to acquisitions of part ownership rights and the aim was to reduce tax avoidance through corporate group-loans. The rules proved to be ineffective since the avoidance continued and the Swedish rules could not tackle the problem.

I det dagliga mötet med elever ställs lärare inför utmaningar som kräver att läraren besitter en förmåga att ta ställning, både etiskt och moraliskt. Dessa utmaningar kan vara av det slaget att de resulterar i en konflikt. Denna konflikt blir ett dilemma då läraren tvingas göra avvägningar mellan olika etiska och moraliska hänsyn, i syfte att hantera situationen. Hanteringen av ett dilemma fodrar en god etisk medvetenhet. En etisk medvetenhet förutsätter ett ansenligt kunnande inom professionens yrkesetik.

The housing sector of today represents for almost 40% of the energy consumption, an energy consumption of which the major part consists of non-renewable energy sources. This is not sustainable and utilization of new energy-efficient technologies in buildings can be a step in the right direction, towards a sustainable energy society.This report has been made on behalf of and in cooperation with Älvstranden Utveckling AB in Gothenburg to examine how future energy-efficient technologies can affect the energy demand in energy-efficient multi-dwelling buildings.The report is based on Älvstrandens passive house, Hamnhuset, a house whose energy consumption is far below the BBR's requirements. The report looks at the opportunities for improvement within windows, insulation, solar energy technologies, as well as white goods. Computer simulations are then made to apply the selected technologies into a reference building. Technologies are selected from an energy efficient perspective and no account has been taken of other aspects such as the economy.

The dry period is usually 6-8 weeks and in this period the basis of the performance in the following lactation is settled. In an average herd about 15% of the cows are dry (Marcussen & Krog Laursen, 2008). In many herd the dry cows are set aside, that means setting aside 15% of your herd, at the time when they are preparing for their next lactation. The recommendation for number of groups differs depending on country traditions or reasons for grouping. If you look at recommendation for feeding, some companies selling feeding equipment advocates one group throughout the dry period, but the number differs from one to three.

Horse owner?s knowledge about horse feeding and nutrition is directly linked to the horse?s health and welfare. According to several studies, both Swedish and foreign, horse owners generally have inadequate knowledge about horse feeding. The housing systems and feeding routines of today differs in many ways from what horses have adapted to through evolution. Wild horses live in harem herds and roam on large open fields, spending about 60 % of the day grazing, mainly grass and herbs.

A shorter dry period length has in studies abroad showed some positive effects among high yielding dairy cows. Among other things it has been suggested that the periparturient metabolic stress becomes lower, that the fertility is improved and dry off becomes gentler for the udder, due to a lower milk yield. The milk yield is generally reduced during the first period after calving, especially among primiparous cows. The aim of this master thesis was to investigate how Swedish cows were affected by a shortened dry period, regarding milk yield, metabolism, health, body condition and body weight from two months before calving to some weeks after calving. Also plasma concentration of lactose during the period before calving was determined.

Since the early 1940s in Sweden, subsidies have been a recurring feature in housing politics.Throughout history, these have been used as a management measure to control theconstruction of housing and to promote the Swedish welfare state. The political parties aretoday disagreeing on how much responsibility the state should carry for citizens housing. Tosolve the conflict, the dwelling has to be defined. Is the dwelling to be considered a socialright, like education and healthcare or is the dwelling to be considered a product for the freemarket, driven by supply and demand?The positive population growth in Stockholm has lead to an increased demand for dwellings.The supply of dwellings has not been growing at the same rate, which has implied higherhousing prices and longer wait for rented apartments.
