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.
Pojkars och flickors brinnande intressen : En analys av 10 elevtexter ur ett genusperspektiv
The main purpose of this study is to analyze texts written by pupils during the national test in the subject Swedish for grade 9 in order to identify and illustrate how they have met the instructions for the writing task including genre. The texts have been analyzed using Palmér & Östlund-Stjärnegårdh?s (2005) model for student text analysis. This model has been supplemented by studying word and sentence length, as well as indexes for level of readability (LIX) and word variation (OVIX) in order to illustrate possible differences in a gender perspective. The results of this study are in line with previous research, as the girls? texts are longer and more descriptive, while the boys? texts are shorter and show a wider range of word variation.
Smarta lokala energisystem, Vision-Teknik-Tillämpning
The energy sector is facing an impending paradigm shift. Today?s technology enables the end-user to generate their own energy locally at home. Furthermore, recently developed storage technologies make it possible to balance energy demand with stored energy and integrate district heating with the local power grid. This means that in the future heat and electric power will interact and energy flows is converted over energy boundaries.
Debatten om övergången från SAB till DDC ? Hur ser den ut?
In 2008 the National Library of Sweden decided to give upClassification system for Swedish libraries and start using DDC(Dewey Decimal Classification) from January 1 2011. Thisdecision has influenced the whole Swedish library system and longbefore the National Library of Sweden took this decision thequestion had been thoroughly discussed and debated in Librariancircles.The aim of this thesis is to find out which arguments have beenintroduced in the debate, if the discussion has changed from beforethe decision to go over to DDC was taken to after wards, and if sohow it has changed. My thesis will discuss the following threequestions:? Which arguments were brought forward in the debate,both for and against a transition?? How has the debate about the Swedish libraries?transition from Classification system for Swedishlibraries to DDC changed from before the decision ofthe Royal Library was taken to after?? What conclusions can you draw from the debatewhich has been led about the transition to DDC?The empirical material consists of six articles dealing with thetransition to DDC and in the analysis of this material I have used atext analyses, analysis of. The analysis shows that more or less thesame arguments for and against have been used in practically allthe articles, and the debate has not changed very much.
Relationen mellan stat och kommun när en flyktingförläggning skall lokaliseras.
AbstractEssay in political science, C-level, by Samanta Pudic´, spring semester 2008. Tutor: Susan Marton. ?The relationship between national government and local municipality when a refugee centre shall be located.?The purpose of this essay is to examine the relationship between government and municipality with the help from the interdependens theory when a refugee centre is located. To be able to say something about the relationship between those two actors I have been using two municipalities as examples.
Källskatt i ett EU-perspektiv : Diskriminering inom nationell rätt?
According to Swedish tax legislation, investment funds are taxed differently depending on if the are Swedish or foreign. The difference between the investment funds lies within the taxation of received dividends and the opportunity to shift the liability of tax of received dividends on to the funds shareholders. This measure is only available to Swedish funds. The question in this thesis is whether this difference is discriminatory against foreign investors and therefore constitutes a forbidden restriction against the free movement of capital stated in article 63 EUF Treaty.The European Court of Justice (ECJ) has given several preliminary rulings on this type of legislation and its compatibility with the principle of free movement of capital. It is not compatible with the free movement according to the court.
Riksintresse; Bevarande eller nyttjande : Vindkraftsutbyggnad inom Natura 2000- områden
Natura 2000 is part of the European Union: s framework to protect and preserve biological diversity. Natura 2000- areas are by the goverment appointed to areas of national interest for preserving nature. Also wind power stations are appointed as of national interest and the reason for this is the goverments goal to get energy from reneweble energysources. This essay describes when both these intrests conflict eachother when it comes to building wind power stations within Natura 2000- areas. The main focus of this essay is a casestudy of two cases from two different counties, Dalarna- and Norrbotten county, where applications have been made to build wind power stations within existing Natura 2000- ares, both cases have reached the court dealing with enviromental issues.
Sjunkande pH i Västerbottens humuslager : en kvantitativ analys
Acidification is a central concept in the environmental debate. The effect of acidification of the soil is a matter of a decreasing amount of cations and thereby a decreasing ability to resist a supply of hydrogen ions to the soil. Acidification has gradually increased in the O horizon in Västerbotten over a 30-year period from the 1970th to the 1990th. The aim of this study was from inventories of The Swedish National Forest Soil Survey and The Swedish National Forest Inventory explain and quantify the acidification that has occurred in the O horizon of two regions in the north of Sweden. Data from SMHI, The Swedish Meteorological and Hydrological Institute, has also been used.
Gender mainstreaming på polska? Om normspridningsprocesser i EU
By the same time as the recent enlargement of the European Union, where Poland became a member, it was officially stated that the gender mainstreaming-policy was to be integrated into every area of EU. NGO:s working as entrepreneurs for the gender mainstreaming norm in Poland supported the accession largely because they believed it would help spreading the norm also on a national level. Qualitatively analyzing the Polish case and the difficulties gender mainstreaming as a norm candidate meets with I contrast expectations with what could actually be EU:s role in this matter.Arguing that EU is a context with room for spreading norms by both bargaining and socialization, this paper takes a social constructivist approach. Gender mainstreaming as a norm is difficult for EU to apply on their members, and thus was not widely discussed during accession negotiations. In the same time.

Sårbarhetsanalys av ett infrastrukturnätverk - Användning av nätverksteorier för sårbarhetsanalys av komplexa nätverk
The aim of this report is to examine the possibilities to use network theories to perform vulnerability analysis on complex networks. The scoop of this work is also to improve the possibilities to chart, analyze and present the vulnerability in a power grid. In this report it has been, using power outage statistics, possible to verify, that network theories can be used to evaluate the vulnerability of an infrastructure network. However further studies to establish values on how vulnerable a network is are needed..
Minoritetspolitik för vem?
Different reports imply that the Roma are an excluded group in numerous areas of both Sweden and Europe. Efforts have been done through the centuries without given intentional results. The past 12 years as a Swedish national minority have not diminished the gap between the Roma and the majority society. How does Sweden create and operate its minority policy especially towards the Roma? We have studied international and national minority policy to see how it is described and implemented in the municipality work.
Den generella projektledaren, finns hen? : Om verksamhetsområde påverkar ledarskapsstil hos projektledare
Projektledare är numera en vanlig titel och projekt används som arbetsform inom en rad olika verksamhetsområden. Det finns också generella utbildningar och certifieringar för projektledare som inte är kopplade till något specifikt verksamhetsområde eller typ av projekt, utan är av generell karaktär. Med utgångspunkt i detta vill denna undersökning titta närmre på hur generell projektledarrollen egentligen är. Kan projektledare som arbetar inom ett verksamhetsområde utan vidare arbeta inom ett annat verksamhetsområde?Att kompetenser i form av projektledningsmetodik och verksamhetsförankring skiljer är naturligt då företag och organisationer använder olika projektledningsmetodiker och bedriver olika slags verksamhet.
Bildundervisning i Turkiet : med exempel från en skola i Istanbul
I meet in my work as art teacher many students of different descent, were they, or their parents, have different school experience than the Swedish. This, in combination with therecent discussion after the Muhammad caricatures about the banning of images in Islamic religion, made me curious to study what art education in a Muslim country looked like. I went to visit the Maramra Egitim Köyü school in Istanbul, Turkey, and especially their art classesfrom grade five to eight, which are the same age of students that I have been working with thelast ten years. This was my first visit to Turkey.The question I ask is: What does the practice of Turkish art education look like, using the Marmara school as an example. Which discourses can I identify in the art teacher practice? What surprised me the most was the frequent visual exposure of the founder of the Turkishstate, Kemal Atatürk.
Rättsäkerhet i den psykiatriska tvångsvården : Lagstiftning och tillämpning
This study examines whether or not there are inherit flaws in Swedish legislation concerning psychiatric institutional care, or in the application of the act, which might lead to the failure of rule of law for the private citizen. Law (1991:1128) concerning psychiatric institutional care in certain instances (LPIC) aims to establish rules which will ensure rule of law for the mentally ill in case of psychiatric institutional care. Despite this, there are legal cases which indicate that these rules, and their implications, are not always considered at the psychiatric wards.The questions at issues which this study aims to answer are thus: Are there any deficiencies concerning rule of law in LPIC 2?3 §§, 4?6 §§, 7?10 §§,15?25 §§ and 32?33 §§ ? This section focuses on LPIC and its design. Whether or not the act adheres to rule of law is examined through a definition which has evolved through discussions of concept based in Peczeniks definition of rule of law.
