Underlag för bedömning av energibrunnar inom vattenskyddsområde

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

Novel anticancer combination therapies using replication-selective oncolytic adenoviruses and chemotherapeutics : investigating cell death mechanisms

Den här studien genomfördes i Helsingborgs kommun som ett examensarbete inom livsmedelstillsynsprogrammet på Lantbruksuniversitet (SLU) i Uppsala. Idén med uppsatsen uppkom efter att författaren deltagit i ett möte på miljökontoret i Helsingborg. En kontroll som gjorts bland livsmedelsbutiker i kommunen visade att 60 % av livsmedelsbutikerna fick underkänt vid inspektioner. De områden som fick flest anmärkningar var rengöring och underhåll av lokaler och utrustning, internrevision och temperaturer i kylar och frysar. Över hälften av butikerna fick underkänt vid kontrollen vilket visar på att det uppenbarligen finns brister i egenkontrollen.

Långtidsuppföljning och artrosutveckling hos hundar kirurgiskt behandlade för ruptur av kraniala korsbandet :

The high incidence of cranial cruciate ligament injury in dogs results in both suffering and significant costs due to treatment and care of affected dogs. Today there are several different technics for surgical treatment in dogs with ruptured cranial cruciate ligament. At University Animal Hospital (UDS), SLU, in Uppsala two fundamentally different methods; TPLO (Tibial Plateau Leveling Osteotomy) and external fixation with suture material are practiced. The aim of this study was to estimate if the different surgery technics result in any difference regarding the function of the dog in a long term perspective. Since motion and function are very affected by arthritis, was the purpose also to determine if there are any differences in developing arthritis between dogs surgical treated with external fixation respectively with TPLO. Development of arthritis is common after surgery or traumatic injuries in a joint, such as cruciate ligament rupture. Unfortunately was the number of dogs in the study to small to achieve two comparable groups.

Modell för ett integrerat skärgårdsskogsbruk : en fallstudie på Kallsö

The forests in the unique archipelago of the Baltic Sea is housing many and high values. For the resident population, which has a central role in sustaining a living archipelago, the forest can contribute to the outcome. The forest also contributes to turn the archipelago into one of Sweden?s most attractive recreational areas. Furthermore, these forests exhibit very high environmental values, and they are an element in the traditional cultural landscape.

Om Lettlands utveckling som destination : en jämförelse av turismindustrin under landets självständighetsperioder

Latvia has been an independent state twice, the first time during the years 1918-1940 and the second time from the year 1991 and ahead. During these two periods Latvia has been a destination for tourists. The aim of this study is to describe how Latvia as a destination has developed during the years of independence. One further aim is to compare what Latvia?s tourism industry looked like during the same periods to descry similarities and differences.

Spåret mot parken : en gränsöverskridande stig mellan torg och park i Norra Sorgenfri

My thesis is a Combination of theory and practice, where theory is meant to create a context and a background for my interpretation proposal. I wanted to ?access? the ideas that are always in the background of the reasoning which underlies both planning in a larger scale, and the design of a place. I wanted to make a ?work of ideas.? In the process of shaping the proposal, I wanted to be deleted from the site itself.

BeAKKta : ett kommunikationshjälpmedel som möter behoven av djupare kommunikation hos personer med autism

A vulnerable group in society is people with ASD (autism spectrum disorders) or autism. This group seems to increase, mainly due to genetic factors but also environmental problems. Medical research has accelerated in the U.S. and Europe. The biggest problem for people with disabilities is the inability to communicate, both verbally and socially.

Utveckling av gran, Douglasgran, bok och tall under skärm av hybridlärk :

?Development of Norway spruce, Douglas fir beech and Scots pine with a larch shelter wood? is a report written by Per-Olof Magnusson. The thesis is a compulsory part of forest engineer program at ?Skogsmästarskolan?, SLU, Skinnskatteberg, Sweden. The purpose of this report is to describe and evaluate an experiment with hybrid larch (Larix x eurolepis) as shelter wood, and different tree species growth and survival depending on the density of the shelter wood. The experiment is conducted by southern Swedish forest research centre, faculty of forestry, SLU in Alnarp. The hybrid larch ought to be an interesting alternative to birch (Betula sp.) as shelterwood on suitable sites in southern Sweden.

Evaluating a corporate strategy : a case study of Länsförsäkringar

The Swedish agricultural sector is currently undergoing a substantial structural change. The number of farm enterprises is continuously decreasing and the average farm size is increasing. In Combination with increasing number of competitors in the insurance market, the competitive rivalry within this market has increased significantly. With this knowledge in mind, Länsförsäkringar Uppsala initiated this study, which aims to provide an understanding of customer?s view on customer value, related to agricultural insurance and financing.

Elevers arbetsklimat, ämnesintresse och medelbetyg i årskurs 9 : Om sambandet mellan dessa tre viktiga aspekter i skolans verksamhet

In the Swedish governing document for the mandatory school (Lpo94) it is laid down that The school shall strive for being a living social community that gives safety and the will and desire to learn. The social community and the social relations in the school everyday existence are thereby without hesitation very important for the students' learning. The teacher always wants to engage the students and create order, comfort and a good work environment. In this essay, the relationship between students' work climates, matter interests and average grades is studied. This gives understanding and awareness in these important parts of the schools´ daily activity.

Miljöbedömning av mark- och vattenresurser i kommunal översiktsplanering : en fallstudie av en del av planprocessen i Tierps kommun

This paper describes the integration of environmental assessment in Swedish municipality comprehensive planning through a chosen case study. The implementation of a new EGdirective in Swedish law, concerning Assessment of the effects of certain plans and programmes on the environment, should lead to some changes in the way Swedish municipalities' deals with environmental issues in their comprehensive plans. This could later on lead to new preconditions for municipality comprehensive planning. The purpose of this study was to investigate how the planning organisation in the municipality adapts to new regulations for impact assessment of comprehensive plans required by the Planning and Building act. Secondly the purpose was to partly participate in the early stages of the planning process and thereby indicate and identify possible environmental impacts regarding the aspects of land and water. This was done as a case study in a well defined part of the process.

Ekologisk aspekt som mervärde : En studie om långsiktig överlevnad för ekologiskt nischade livsmedelsföretag

Background: With the increased globalization food prices went down for a while, only to skyrocket to new levels. Prices of organic food, which already were more expensive than conventional, are now even more expensive. The current financial crisis results in reduced consumption which creates a threat to the smaller grocery stores. Globalization and the increased competition have had a negative impact on the environment but at the same time the desire to solve these issues has increased appreciably. The environmental aspect has been given higher priority by the individual, which led to a wider range of organic products and dramatically increased the number of stores selling organic products, leading to a greater competition among the stores selling organic food.  Problem definition: What factors are important for organic retail business long term survival?Purpose: Trough case studies analyze and evaluate the organic niche retail companies? strategies of marketing.Methods: This study is based on both qualitative and quantitative research methods.

Affärsupplägg biobränsle Västerbotten : en undersökning av större biobränsleanvändares syn på biobränslemarknaden i Västerbotten

The use of bio energy in Sweden has increased during the last few years and with every passing year, bio energy produces 3-4 TWh´s more energy than the previous year. The increase in the use of bio energy makes it an interesting prospect for forest companies to produce bio energy from the forest. Sveaskog has a fairly extensive bio energy programme, mainly in southern and middle Sweden. Their activity regarding bio energy in northern Sweden has been very restrictive or even non-existent. Because of this, during the winter of 2003-2004, Sveaskog initiated a number of degree projects with the purpose of looking at the use of bio energy in northern Sweden.
