Halvledare för höga strömmar i fordon
Mechanical relays are more and more being replaced with semiconductortechnology. In this thesis it is investigated if and how the larger loads couldbe controlled by transistors. The main part of this work aims to create andverify a solution that can control the starter motor, as well as protect it incase of any failure. The different malfunctions that the solution protectsagainst is high current, too high peak current, low current, maximum cranktime and minimum cool off time. The timers also protect indirectly againstoverheating of the starter engine.The transistors used are BTS555, from Infineon.
Vakuumisolering ? Ekonomiskt försvarbart för småhus?
The number of people in the world and the urbanization increases. This leads to a bigger need of space for the built environment, space that soon doesn?t exist. A large portion of humanity?s energy disposal is used for heating of buildings.
Isolating microorganisms from marine and marine-associated samples : a targeted search for novel natural antibiotics
The search for antibiotic compounds from the natural environment has been going on for seven decades, ever since penicillin entered the market and antibiotic treatments became routine. The evolutionary pressure put on the pathogenic microorganisms induced a rapid spreading of naturally occurring resistance genes, leaving only the option of finding new antibiotics to treat the resistant pathogens. Microorganisms have been extensively mined for their biosynthetic abilities to produce biologically active compounds. To date, more than 23 000 microbial natural products have been discovered. The Actinomycetales are ubiquitous bacteria that have been used for antibiotic discovery for more than half a century, and over 10 000 natural products have been identified from the order.
Egyptiernas föreställningar om döden : en diskursiv analys av Dödsbokens formler
The Egyptian religion viewed the whole world as divine and inhabited by both gods and men. Concepts such as death was therefore explained through myths. The ancient society feared death but desired an eternal life. The Egyptians saw death as a physical dismemberment of the body as had happened in the myth of Osiris when death was first introduced to the world. Osiris functioned as a prototype for all men as he had overcome death by finding a new existence in the netherworld.
Svensk yttrandefrihet i ett EU-perspektiv : - Hur svenska medborgare kan komma att få ett svagare meddelarskydd och ensamansvar ioch med EG-rättens konflikt med svensk grundlag vid grundlagsregleringen 2010
AbstractTitle: Swedish freedom of speech compared to european freedom of speechNumber of pages: 57Author: Gabriella BoodeTutor: Göran SvenssonCourse: Media and Communication Studies CPeriod: Spring 2009University: Division of Media and Communication, Department of Information Science,Uppsala UniversityPurpose/Aim: The purpose with the dissertation is to see if there has been a limitation inSwedish freedom of speech since parts of the European union laws is superiour to theSwedish constitution as freedom of the press regulations and freedom of speech constitution.A more narrow purpose is to find out how the specific Swedish rights such as individual?slegal right to publish information are influenced by the European union laws and are superiorto the freedom of the press regulations and freedom of speech constitutionThe survey will also try to find out the effectiveness with the Lisbon Strategy ?s emergencybrake and its purpose to protect the Swedish freedom of the press regulations and freedom ofspeech constitution. How big is the difference between the different member states concerningthe protection of the freedom of speech?Material/Method: The data collected for this thesis is retrieved through personal interviewswith representives from experts with in the field as Uppsala University and the SwedishGovernent.Main results: It is obvious that Sweden has the strongest protection of freedom of speechcomparing to the other EU member states.

Livscykelanalys och optimering av isoleringstjocklek för moderna byggnader : - med fokus på kv Limnologen i Växjö
Syftet med denna rapport är att visa hur en ökning av isolertjockleken i ett hus påverkar kostnader och energiåtgång för isoleringen i ett livscykelperspektiv, samt för husets bruksskede. I studien har en optimering av isoleringen på ett pågående byggprojekt i Växjö, kv Limnologen, utförts. Total energiåtgång för isoleringens livscykel har tagits fram från tidigare utförda livscykelanalyser (LCA). Husets värmebehov har beräknats mha information från ritningar och kontakter med personer i anknytning till kv Limnologen. En ekvation har utformats för att finna ett teoretiskt optimum för isolertjockleken med inriktning mot total energiåtgång, koldioxidutsläpp och ekonomi.
Att vårdas för MRSA : En litteraturöversikt om patienters upplevelser av MRSA-vård
Bakgrund: Meticillinresistenta Staphylococcus aureus (MRSA) ökar drastiskt inom sjukvården både i Sverige och i hela världen. Bakterien sprids vanligast från patient till patient via vårdpersonal då restriktioner om basala hygienrutiner inte följs. Att bli smittad med MRSA kan leda till svåra konsekvenser för patienter i form av infektioner i operationssår, i implanterade proteser, på hjärtklaffar, i lungorna och på hjärnhinnor. Patienter med MRSA vårdas i isolering för att förebygga att MRSA sprids vidare, vilket kan orsaka lidande hos patienter. Syfte: Denna uppsats syftar till att beskriva patienters upplevelser av MRSA-vård. Metod: Nio vetenskapliga kvalitativa artiklar ligger till grund för denna litteraturöversikt. Artiklarna har analyserats och sammanställts och nya teman uppkom efter de likheter som framkom i deras resultatdelar. Resultat: Resultatet visar att vårdandet förändrades efter MRSA-diagnos.
Kan fysisk aktivitet förebygga Alzheimers sjukdom? En litteraturbaserad studie.
Introduction: We are facing an aging population, which means that the incidence of age related diseases, such as Alzheimer's disease, are expected to increase. In the current situation there is no cure for the disease, whereupon it is important to develop preventive strategies. Objective: To examine the association between Alzheimer's disease and physical activity. Method: A systematic literature search was done to identify the current state of knowledge from the year 2006 onwards. The reason for this limitation was that the SBU commissioned a systematic literature review in 2006, where the relationship between physical activity and Alzheimer's disease could not be determined.
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.
Social kontakt för hund i rastgård ? när kan kraven anses uppfyllda?
People in Sweden have more and more dogs in their care, and several of these dogs are kept in kennels in back yards for various reasons. According to Swedish animal welfare legislations the need for social contact for dogs has to be met. However, there are few details presented on how to meet the need and when it can be considered satisfied. Does the dog need human contact to fulfill the need, or is the company of other dogs enough? This study aims to specify what can be acceptable when it comes to fulfilling dogs? social needs in accordance with the Swedish animal welfare legislation.
Miljökonsekvenser av dagvattendamm i Skebäck, Örebro : en fallstudie hur miljöpåverkan av en dagvattendamm intill ett Natura 2000-område kan bedömas
Stormwater is surface runoff water that originates from precipitation or snowmelt and that on hardened surfaces prevents to infiltrate the ground. In city areas stormwater can consists of major amounts pollutants and when reaching a lake or watercourse it can cause damages on vegetation and animals. Therefore it is important to treat polluted stormwater before it reaches the recipient.
The municipality of Örebro have since the 90ies an extensive work with treatment of stormwater in sedimentation ponds. A new stormwater treatment project is planned in an industrial estate in Skebäck, Örebro.
Kartläggning av faktorer som kan minska antalet återinkopplingar i elnätet
Vattenfall Eldistribution AB distribuerar el till ca 900 000 kunder i Sverige. Det handlar om både privatkunder och företagskunder. Enheten Nätdrift vars driftcentral är placerad i Trollhättan har till uppgift att se till att elnätet är spänningssatt och att man skall minimera avbrottstiderna.Då dagens samhälle är allt mer beroende av störningsfri leverans av el är det viktigt att kartlägga faktorer som orsakar korta avbrott på nätet. Ett kort avbrott definieras som ett avbrott som varar allt från 100 millisekunder till 3 min. I myndigheternas föreskrifter finns inga krav angående hur frekvent korta avbrott får förekomma i elnätet, då dessa avbrott oftast är orsakade av åska och därmed omöjliga att förutse.
Som om min kropp var giftig : En litteraturo?versikt om hur personer med HIV upplever ha?lso- och sjukva?rdspersonalens bemo?tande
Bakgrund: Human immunodeficiency virus (HIV) är en kronisk sjukdom som successivt försämrar det mänskliga immunförsvaret. Det finns medicinsk behandling som leder till ökad livslängd. Detta innebär att antalet personer med HIV kommer att öka och hälso- och sjukvårdspersonal kommer att kunna möta dessa personer inom flera vårdkontexter än enbart i HIV-specifika sammanhang. HIV har varit en uppmärksammad sjukdom sedan 1980-talet och den diskriminering och stigmatisering som sjukdomen mötte då finns kvar idag, trots nationella och globala lagar och riktlinjer.Syfte: Syftet med denna litteraturöversikt var att beskriva hur personer med HIV upplever hälso- och sjukvårdspersonalens bemötande.Metod: Metoden för denna litteraturöversikt inkluderar tio vetenskapliga artiklar hämtade från databaserna CINAHL och PubMed. Av dessa var två kvantitativa och åtta kvalitativa.
Rödluvan och vargen : En kvalitativ textanalys av debatter och adaptationer i barnlitteraturen
This two years master?s thesis is a review and exploration of the Swedish debate concerning children?s literature from the 19th century to the present, as well as the evaluation and analysis of four adaptations of the tale Red Riding Hood. The aims are to identify how ideas and values regarding the role of children?s literature in society have developed over time and to contribute with a knowledge base for continued reflection and discussion on the subject of children?s reading and mediation of children?s literature in public libraries.The theory and method used in the thesis, is primarily based on the discourse analysis of Michel Foucault. I have identified four main discourses: the educational discourse, the liberation discourse, the politicized dis- course and the popular discourse.
Växtinventering och skötselåtgärder : en studie av Rektorsgårdens trädgård i Uppsala
The Bovine respiratory syncytial virus (BRSV) causes bronchiolitis and interstitial pneumonia, predominantly in calves, and is a major cause of bovine respiratory disease worldwide. In humans, BRSV is paralleled by the closely related Human respiratory syncytial virus (HRSV), an important cause of respiratory disease, most severe in infants.The clinical signs and pathology during RSV infection is caused, not only by the direct effects of viral replication, but also by the response of the host immune system. The immunopathology of RSV has long obfuscated our understanding of the disease, and development of effective treatment and vaccines will be very difficult until greater knowledge is gained.One of the components of the immune system that has come into focus in RSV research the last few years, is the Toll-like receptor 4 (TLR4). The TLR4 receptor is well known as the receptor that binds lipopolysaccaride (LPS), and initiates the host response to bacterial infection. Recently, it has been shown that the fusion protein of RSV also interacts with, and up-regulates the expression of, the TLR4 receptor.
