Migration losses of Atlantic salmon (Salmo salar L.) smolts at a hydropower station area in River Åbyälven, Northern Sweden : passage fates at a reservoir, a power house and a bypass structure

A large number of rivers in northern Sweden have hydropower developments that cause negative effects on both up- and downstream migrations of anadromous species like Atlantic salmon. So far, most attention has focused on the hindrances of adult fish during their upstream spawning migration. However, since turbines in power stations cause losses on downstream passing fish, the focus on negative effects on smolts has increased. The aim of this study was to compare three different causes of losses of salmon smolts passing downstream through a power station area in the flow-controlled River Åbyälven in northern Sweden.A total of 61 wild salmon smolts were caught and radio-tagged in the River Åbyälven during their downstream migration in June 2009. The salmon smolts were released at three locations, 1.1 km upstream from the power station, in the turbine intake and in the upper part of a fishway, acting both for up- and downstream fish passage.

Mjölkraskvigors tillväxt på naturbete :

To turn the dairy heifers out on pasture is the most natural way for the cattle to get feed. At the same time it is cheap and if it is right treated a feed of high nutritive value. The problem today is to get dairy heifers to grow enough when they are grazing at natural pasture for the entire summer. Therefore, the opinions differ whether pasture is a resource or a problem. The increasing interest of pasture production is due to the fact that you can receive grants for preserving valuable natural assets and cultural landscape elements in the pasture land. A high grazing pressure is necessary to preserve an open landscape and a great variety of species. In the same time the heifers have to supply their nutritive needs in order to grow and be large enough to show heat and be pregnant in right time to calve with a sufficient body size and at an economically right age. This paper includes a literature review on natural pasture, pasture production, and growth of dairy heifers together with own interviews with dairy farmers about their point of view to the pasture husbandry on the farms, how they plan for pasture, look after natural pasture, treatment areas and take care of the calves and heifers. The results indicate that the time it takes and the demanded work are the biggest factors to how and why the farmers do as they do..

Approximately 4 500 members of staff are employed, of whom around 120 are political appointees. For this study, interviews have been conducted with 15 senior officials and political appointees at the Government Ministries and the Prime Ministers Office. The interviews have been supplemented with literature studies based on user studies research in library and information science.

Landskapsplanering ur ett hållbarhetsperspektiv :

Environmental problems are accelerating with energy consumption and the release of greenhouse gases as the major issues. This affects landscape planning mostly through environmentally hazardous transportation and heating of buildings. In environmental work, the term "Sustainable development" is often used. This term was coined in the Bruntland report in 1987. A number of frameworks have been developed to clarify the term and to remind the user about relevant aspects of sustainability.

Japansk 2D grafisk animation : uppkomst och influenser

In 1896, a French cinema pioneer named George Méliès demonstrated that an object could be set to motion by changing the objects shape or movement frame by frame. But it was not until the early 1900s that this specific genre of filmmaking became a great success. The animations were essentially short and were animated and published in The United States of America. The interest in animated movies began to increase, not only in the west, but also in Europe and Asia. The art of animation grew especially popular in Japan, and emerged as a parallel to Japanese comic books known more commonly as Manga.The history of Japanese animation is not as commonly known as the history of American animation.

Produktutveckling av en sadelpadd

Den här rapporten redogör för utveckling, design och sömnadskonstruktion för en sadelpadd. Rapportens ämne valdes för att jag fann det intressant och har själv stort intresse för hästar och produktutveckling. Fokus på rapporten låg på att ta fram en fungerade prototyp som testades av hästägare för att se om en distansväv skulle klara av att vara det stötdämpande och tryckutjämnande materialet i en sadelpadd. Rapporten och utvecklingen av rapporten bygger på en enkätundersökning och några intervjuer med relevanta personer insatta i ämnena sadelpadd och ryggskador hos hästar. Utifrån den insamlade informationen från de intervjuade och de som svarade på enkäten samt tidgare skrivna källor gjordes en studie i hästars uppkomst av ryggbesvär.

Fastighetsmäklarens klädsel : Hur påverkar den kunden?

Real estate managers work in a hard branch with big competition and skeptical customers. For most people, buying a property is the biggest private purchase of their lives. This puts a big pressure on the real estate agent to make the process run smooth. But how does the customer know which real estate manager to choose? We have researched what effect the real estate managers clothing has on the customers? first impression and how clothing affects customers? choice of real estate agents.To answer our questions we´ve done 13 projective interviews with ten customers and three real estate agents, where we showed four pictures with the same person dressed in different styles.

Nyckeln till self-efficacy : Beslutsfrihet, stress från föräldrar och optimism under sena tonåren

Enligt Bandura (1997) är self-efficacy tron på den egna förmågan att slutföra uppgifter och nå mål. Denna studie undersökte sambandet mellan upplevd beslutsfrihet under sena tonåren, upplevd stress från föräldrar under sena tonåren, upplevd optimism under sena tonåren och self-efficacy. Stickprovet på 133 studenter, varav 35 män och två av okänt kön skattade sina upplevelser och self-efficacy. En multipel hierarkisk regressionsanalys visade att self-efficacy korrelerade positivt med både beslutsfrihet och optimism vilket gav stöd för hypotes 1 och 3. Variationen i de oberoende variablerna och kontrollvariablerna kunde förklara 12% av variationen i self-efficacy.

Adderande tillverkning för metall

The Swedish automotive industry has since way back been struggling with bankruptcy, abroad buy outs and staff cuts. Competition and pressure on prices are two factors that affect the automotive industry. Because of this, the companies are pressured to continuously developing their work in addition to be able to compete on the market. The aircraft industry has successfully managed to implement additive manufacturing (AM) and for motorsport has several components manufactured with AM been used. When AM is used as a manufacturing method, there are a number of advantagesthat follows.

Administrativ styrning möter akademisk frihet Om Lunds universitets översättning av populära organisationsrecept

In a world of ?formal organizations?, which is constantly exposed for institutionalized super standards and ideas of a what a modern orgnization should be like, the pressure for changes are strong. This is the environment in which Lund University finds itself. Ideas in the beginning of the 21-century is concerning a stronger emfasis on steering, centralisation, re-hieriarchyzation, standardised processes and a new regulation concerning internal control. Through theories of new institutionalism, with conceptions as organizational identity and the expectations of adapting to new ideas, can you track the translation and adaptation that the ideas go through at the university- a decentralised organization where not only freedom has been a concept for the academic parts, but also for the administration.

Schweiz integration på den inre marknaden. En undersökning av Schweiz övertagande av acquin.

Standing outside the EU and the EES, Switzerland is a unique state characterized by federalism, direct democracy and neutrality. Though always focused on preserving these features and its sovereignty, Switzerland has managed to gain access to some sectors of the single market through bilateral agreements with the EU. The purpose of this thesis is to examine what level of integration Switzerland has reached in those bilaterally regulated sectors of the single market. As integration cannot easily be assessed, the extent of the Swiss adoption of the acquis is seen as an indicator of the level of integration and is thus examined. The conclusion is that Switzerland, mostly due to the economic interest of common rules, but partly due to pressure from the EU, almost completely adopts the acquis in the bilaterally regulated sectors, including the interpretation of the ECJ.

Organisation och marknadsorientering av äldreomsorgen : En jämförelse mellan Sverige och Tyskland

Organisation and market orientation of elderly careThis comparative literature study is intended to describe how elderly care is organised and financed in Germany and Sweden. Furthermore, it analyses the degree of competition and market orientation in both countries' care systems. Important aspects in this context are the kinds of measurements which are used on the two markets and the question if there are quasimarkets.The theoretical backgrounds of the study are Esping-Andersen's "Three Worlds of Welfare Capitalism" and Harold Wilensky's convergence theory. Esping-Andersen's theory describes Sweden as a social democratic and Germany as a conservative welfare regime which means that there are different conditions for the development of welfare. The use of Wilensky's theory shows that both welfare systems are converging since the end of the 20th century.

Fånggrödor i Norra Östersjöns vattendistrikt

70 % of the lakes and waters in the water district of northern Baltic Sea do not reach the requirements for good ecological status. This is mostly due to eutrophication caused by a too high deliverance of nutrients from agricultural land or effluents. Losses of particulate phosphorus through water erosion contribute to a great extent to this eutrophication. In the action plan for the water district cover crops are mentioned as a measure for reducing losses of phosphorus from arable land. This paper reviews the possible effect of cover crops in the water district and discusses what crop that would be most suitable.

Nya renings- och uppgraderingstekniker för biogas

Biogas is a renewable energy source that is produced by anaerobic digestion of organic mate-rial. In Sweden, biogas predominately comes from sewage water sludge and landfills or from organic waste of households and industries. Small scale digestion plants at farms are espe-cially expected to contribute to increased biogas production in the future. Biogas can be ob-tained directly in it?s raw form and used as fuel in a combustion chamber.
