Optimering av ett småskaligtvattenkraftsystem

This master thesis covers the seasonal planning of a small scale hydropower system. The system in this study is owned and operated by Mälarenergi Vattenkraft AB. The total system consists of 4 different main rivers with 24 hydropower stations and several dams. The total installed power in the system is 43.75 MW. Most of the hydropower stations are regarded as small scale hydropower stations and thus entitled to green certificates.In this report the issue of planning is formulated as an optimization problem.

Varför oroar vi oss och vad oroar vi oss över? Skillnader mellan högoroare och lågoroare.

Oro är ett allmänmänskligt fenomen som kan vara både till nytta och skada för oss. Syftet med denna studie var att undersöka om det finns någon skillnad mellan högoroare respektive lågoroare vad gäller vilken funktion oron fyller (Worry Automatic Thought Questionnaire) och orosinnehåll (Student Worry Scale), undersöka eventuella könsskillnader samt jämföra ett mått på frekvens och intensitet i den allmänna oron (Penn State Worry Questionnaire) med ett allmänt ångestmått (Beck Anxiety Inventory). Undersökningsdeltagarna utgjordes av 40 psykologistudenter och 70 polisstudenter och könsfördelningen var jämn. Signifikant samband mellan totalpoäng på PSWQ och totalpoäng på BAI erhölls. Högoroare oroade sig signifikant mer av vidskepliga skäl, för att undvika eller förhindra något ont från att hända, i förberedande syfte, för att få motivation samt som distraktion från mer emotionella saker, jämfört med lågoroare.

Wolf movement patterns and the distribution of moose kills : implications for human harvest?

Most studies regarding wolf (Canis lupus) predation on moose (Alces alces) have focused on the total annual consumption of moose within a wolf territory but few have tried to describe the spatial impact of wolf predation on a local scale. In this study I have analyzed wolf movement data, wolf predation, moose hunting statistics and moose hunter observations to investigate how wolf predation affects the human harvest of moose in Scandinavia. Since wolves prey on mostly juvenile moose during summer, analysis of their summer movement patterns is crucial to understand its impact on the human harvest later during autumn. In this study both reproducing (n = 45) and non-reproducing wolves (n = 12) reduced their movement range during summer to 66% and 67% of their annual movement range, respectively. Reproducing wolves increased their movement range from early to late summer while non reproducing wolves did not.

Ett företag i förändring: en fallstudie av en riskkapitalbolagsdriven förändringsprocess

Venture capital firms and private equity firms have been the subject of much controversy in the last decade. During this period economies throughout the world have seen a steady increase of these types of firms as owners of companies. In Sweden this has certainly been the case and many argue that this trend will continue to grow stronger in the future. This trend is by many regarded as dangerous and as a threat to the ownership model that has characterized the Swedish economy for decades. Family ownership has been widely regarded as the most beneficial and responsible ownership model in Sweden.

Ruminants´production within agroforestry systems in rural Rwanda : production benefits and problems

Intercropping involving trees is called agroforestry and makes it possible to get higher production for every area unit. The trees can function as food, fodder, fuel, medicine; prevent mark erosion and much more. Agroforestry can also be combined with animal husbandry. The aim of this study was to document the animal production systems used by rural small-scale farmers maintaining ruminants and using agroforestry in the northern province of Rwanda. The farmers using agroforestry is expected to have higher milk yield than average due to homegrown protein. The method used during the study was semi-structural interviews with booth open and closed questions. In order to get in contact with farmers that matched the criteria; small-scaled rural farmers with ruminants and using agroforestry, the ?Vi Agroforestry Programme? (Vi-Life) in Kigali were contacted and the staff worked as supervisors, translators and contact with the farmers throughout the study. During the study nine individual farmers, two cooperatives breeding sheep and one group interview were conducted.

Sjuksköterskans erfarenhet vid omvårdnad av familj vars nyfödda just fått diagnosen Downs syndrom

Introduction: About 160 children with Down syndrome are born each year in Sweden. They will spend their first time in life at the neonatal departments around the country. Previous research has shown that parents in these situations have experienced an unsatisfying behaviour from the caregivers and that they are not getting the care they desire. However the research that reflects the nurses? role in these situations is sparsely studied.

Gårdsbaserad biogas på Nya Skottorp : utvärdering och optimering av anläggningen och uppgradering av biogasen

Biogas is an expanding sector within the broad field of agriculture and animal production. Small-scale biogas offers local combined power and heating production and the substrate is transformed into high-quality biological fertilizer. This bachelor thesis focuses on a pig farm in south-western Sweden, where biogas is produced from pig manure, evaluates and suggests ways of optimizing the process and investigates whether investing in an upgrading plant would be a feasible and more cost-efficient option. The results show that the biogas plant is working well, although the production differs from the original plans. This shows in turn that planning and examining the basic conditions before making the investment is of great importance, as well as monitoring and keeping detailed statistics of the running process.

Marknadsinträde i Kina? : de svåraste inträdesbarriärerna för svenska företag vid marknadsinträde i Kina

China is considered as one of the world?s fastest growing economies and the future of China looks promising. Even though the Chinese market attracts many new foreign companies to enter the market there are entry barriers which companies may encounter as obstacles, which will aggravate the market entry in China. As a result companies loose business opportunities and therefore it is of great importance for Swedish companies, which are planning a Chinese market entry, to identify which entry barriers that are considered to be the most difficult obstacles to overcome.The purpose of the thesis is to examine which entry barriers that are generally considered to be the most difficult obstacles for Swedish companies to overcome when entering Chinese markets and to rank the five most difficult entry barriers to overcome.Information about these entry barriers have been gathered from Swedish companies, which have carried out successful market entries in the Chinese markets, through an e-mail questionnaire.The result generally shows that the most difficult entry barriers to overcome in China were: bureaucracy, property laws, language, cultural differences and difficulties finding local partners. The ranking of the entry barriers? result shows that bureaucracy is the most difficult obstacle to overcome, followed by cultural differences, language, relations and access to distribution channels.We conclude that companies experience different difficulties overcoming these entry barriers, which depends on the companies? size, years in China, markets and if the entry barriers were considered controllable or uncontrollable.

Kommasköldlusen Lepidosaphes ulmi (Linnaeus) i svensk äppelodling : livscykel och naturliga fiender

Lepidosaphes ulmi ? kommasköldlusen har dykt upp som skadegörare i svenska äppelodlingar de senaste åren. Svenska äppelodlare har efterfrågat mer information kring kommasköldlusen och dess naturliga fiender, och därför gjordes denna litteraturstudie. Kommasköldlusen är en pansarsköldlus med ett hårt skyddande skal. Även äggen läggs under skalet och de är därför svåra att bekämpa.

Samverkansplanering : en jämförande studie mellan praktik och teori

Collaborative planning ? a comparative study of theory and practice Why There is today, according to my experience, a growing interest and demand for a more inclusive and transparent planning process. Also, if we are going to be able to reach a truly sustainable society it is my belief that there is a need for a more integrated collaboration between different actors. Where the social, economic and ecological values can influence and benefit from each other. The question then is, how can the planning system accommodate that kind of collaboration? Purpose My aim for this thesis has been to study a selection of the theoretical work that exist about collaborative planning.

Småskalig vattenkraft vid Olofsfors bruksmuseum : Med faunapassage

In Sweden there are 1894 small-scale hydropower plants in operation, which together generate 4.3 TWh of electricity per year according to Swedish hydropower compound (SVKF, 2011). This corresponds to the annual consumption of about 860,000 Swedish households (based on an annual consumption of 5000 kWh). In the mid-1950s there were around 4000 small-scale hydropower plants in operation in Sweden before cheap fossil fuels and uranium competed with them, in the current situation only 1,894 of these are in use. If slumbering small hydropower plants once again would be taken into use and some new ones are built, we would be able to extract about 7 TWh of renewable electricity from these annually in Sweden, representing about 1.4 million households.The thesis intends to calculate and construct a hydroelectric power plant at the existing dam in Olofsfors and give suggestions on how the power station should run during the time that fish migration is greatest in Leduån.The turbine and generator to the station in Leduån at Olofsfors is designed by the height of the fall and the water flow through the dam. The turbine selected for the station is a CK-1000RM turbine with a 4-pole 250 kW generator from Cargo & power turbine Sweden AB, which is expected to deliver 1.2 GWh per year.
