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.

Modell av en synkronmaskin för PSCAD/EMTDC med magnetisk mättning i d-led och elektriskt gränssnitt för fältmatare

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

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.

Två presentationstekniker för grafer : deras styrkor respektive svagheter inom en bioinformatisk kontext

This degree project has been carried out in cooperation with Enertech AB in Ljungby and is pilot study to automating all current manual soldering. The soldering process accounts for a large part of the processing cost in the production of a heat pump. The process is also a quality risk and has a major impact on the lifetime of the final product.The Main task of this project has been to evaluate automation of the soldering process, to develop automation solutions and a principle layout, to draw the design changes required for the automation and to calculate the supposed solution.This pilot study has resulted in a suggested automation solution using laser as a heat source for soldering. Calculations of the solution show that a automating a laser soldering cell is very profitable..

Studie av Brooks Lag och Kirurgteamsmetoden med hänsyn till öppen källkod

Uppsatsens behandlar de speciella fördelar ochnackdelar som uppstår när utvecklare släpper kodunder öppen källkod. Framförallt studerasproblematiken med Brooks lag som säger att när flerpersoner läggs till i ett försenat utvecklingsprojektblir projektet ännu mer försenat. Denna problematikstuderas utifrån ett öppet källkodsperspektiv därutvecklare utanför projektet kan sända in kod ochförslag på förändringar när som helst underprojektets gång. Uppsatsen försöker att utifrånutvecklingsmetoden kirurgteamet, formulerad avFredrick Brooks, finna en lämplig metod därutvecklingsarbetet går så smidigt som möjligt utanatt försaka de fördelar det innebär att kunna ta emothjälp utifrån. Uppsatsen är framförallt en kvalitativlitteraturstudie där fokus ligger på att studera ochsammanställa befintlig litteratur för att dra generellaslutsatser utifrån denna..

Ungdomars riskförståelse angående damm (brott)

Requirements engineering is a widespread topic in the research field of informatics. However, there is little research regarding lack of requirements documentation and how it is perceived. The same applies for how requirements engineering in retrospect can be implemented. This is a debated issue on blogs and forums but it has not been reflected in the research area.Therefore, this study concerns research questions regarding how the developers, testers and requirements analyst experience the lack of requirements documentation and how requirements engineering in retrospect can be implemented.To answer these questions, data collection has been conducted through qualitative interviews with individuals affected by this problem in their everyday work.This study has provided an explanation of how the problem is perceived and what the consequences are, both direct and indirect. The impacts are divided into three categories and are presented as, emotional consequences, system implications and consequences regarding re source consumption.

Implementation av ett Content Management System

Under de senaste åren har webbplatser blivit allt mer komplexa och informationen som ska visas och hanteras allt större. För att underlätta hantering och administration av dessa system har många CMS-system vuxit fram. Dessa system kan skilja sig mycket beträffande pris och funktionalitet, allt från mindre open source system till stora komplexa kommersiellt drivna system. Detta arbete bygger på att skräddarsy ett CMS-system för administration och hantering av innehåll på diverse artist sidor, som hanteras av ett medieföretag. Systemet använder tekniker som JavaScript, PHP, MySQL som grund för dess uppbyggnad.

Prefabricerade stödmurar i betong :

This is a booklet with information and inspiration about precast retaining walls. The three chapters contain information about concrete as a material, how the surface of the wall can be altered, and a chapter with ideas for a new precast wall. I have obtained information through books, interviews, lectures and fairs. The retaining walls on the market do not correspond to the requirements of the Landscape Architects I have interviewed. I have therefore considered their opinions in the chapter containing my new ideas for new retaining walls.

Alternativ till Oracle utifrån Lantmäteriets förhållanden

Lantmäteriet i Gävle är ett företag som hanterar mycket stora datamängder i databaser och det är därför av stor vikt att de har ett väl fungerande databashanteringssystem. De använder sig av databashanteringssystemet Oracle, men intresse för alternativ finns. Lantmäteriet önskade därför en rapport som jämför deras nuvarande databashanteringssystem Oracle 10.2.0.3 med möjliga alternativ. De databashanteringssystem som i denna rapport jämfördes med Oracle är Microsoft SQL Server 2005 och MySQL 5.1. Aspekter som studerades är prestanda, kostnad, säkerhet, kompatibilitet, tillgänglighet och support.

Abstract: When playing in teams, communication is important, not just communication with words but also non-verbal communication such as gestures and body languish. The purpose with this study is to see how there is a co-op among communicating players , between leaders and players and to examine what meaning communication and culture got  in a youth team. The ambition with this study was to increase our knowledge about communication and communicationculture in the youth floorball team. This study is qualitative and was inspired by an ethnographical method so we got the information from observations of a youth floorball team, totally we made four observations. The result were analyzed and categorized from our observation papers.

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.

Immigration och integration i kommunpolitiken : En studie av immigranters representation avseende förtroendeuppdrag i Växjö Kommun 1971-1991

The present study discusses the political integration of immigrants in local government in the muncipality of Växjö from 1971 to 1991 in the form of representation. The main data source consists of lists of people holding local commissions of trust in the various boards and committés appointed by the municipality council, as well as in the council itself. These data are then compared to population statistics from Statistics Sweden. Main findings of the study are that immigrants are insufficiently represented in relation to their proportion of the population. It is suggested that this is a result of structural discrimination and possibly insufficient socialisation..
