Fuktstudie om uteluftsventilerade vindar med beräkningsprogrammet Simple Cold Attic Model från Annex 55
Fuktskador på uteluftsventilerade vindar är ett ökat problem, i det mer miljömedvetna Sverige. Genom tjockare vindsbjälklagsisolering minskar både energiförlusten genom bjälklaget och uppvärmningsbehovet i huset, men hur många funderar på vad som händer med det förändrade klimatet på vinden och hur det kan påverka fuktförhållandena i utsatta delar av konstruktionen.Studier från Chalmers Tekniska Högskola har framställt ett fuktberäkningsprogram för uteluftsventilerade vindar vid namn Simple Cold Attic Model. Programmets funktion och potential har prövats i denna rapport genom en beräkningsanalys av en uteluftsventilerad vindskonstruktion. Försök till att förbättra fuktsäkerheten i konstruktionen har utförts och redovisas i rapporten. Studien har påvisat att den studerade konstruktionen inte är fuktsäker om den uppförs i Stockholmsområdet. Det visades även att aktiva val i konstruktionen kan förebygga fuktskador. Studien har påvisat vikten av inte beräkna med medelår för klimat och hur det påverkar beräkningsresultatet av mögeltillväxt.

Comparison of real-time PCR assays for screening of meticillin-resistant Staphylococcus aureus
Staphylococcus aureus belongs to the normal flora. Many healthy people are colonized by the bacterium mainly in the nose but also on the skin and on other mucous membranes without showing symptoms. After damage to the skin, the bacterium can enter the wound and cause infections. Methicillin-resistant S. aureus (MRSA) is resistant to b-lactam antibiotics such as penicillin and methicillin.
Vad är flerspråkighet? : En fallstudie från två skolor i Södertälje
The purpose with this essay is to see if billingualism is understood within the litterature, in the society and among students and facultyteachers. We have read interresting theoris about billingualism and we brought this with us to the schools when we interviewed two principals in two seperate schools and when we performed an investigation, in a form of questionnaries, in one of the schools. They where made with teachers and students in ninth grade. We´ve divided the studie in three parts: the first part contains a theoretical background of what billingualism is. The second part is a presentation of the interviews and the answers from the students and the teachers.
Självspridning av contortatall (Pinus contorta) på impedimentmark i Sverige
I Sverige finns det ungefär 475 000 hektar skogsmark där den från Kanada introducerade contortatallen (Pinus contorta) utgör mer än 65 % av den totala grundytan. Genom aktiv skogsanläggning har P. contorta blivit Sveriges sjunde vanligaste trädart sett i ett volymmässigt perspektiv. Därför är det av stor vikt att ha god kännedom om hur arten sprider sig i det svenska skogsekosystemet.
När P. contorta introducerades ansågs den sakna förmåga att självsprida sig (fröså sig), men senare visade det sig att andelen serotina kottar varierar mellan olika träd och att den kan självsprida sig på produktiv skogsmark.
Resultatet av studien visar att P.
NATO:s luftstridsoperationer i Kosovo : Dess legalitet ur ett nytt perspektiv
I mars 1999 inledde NATO operationen Allied Force i dåvarande Förbundsrepubliken Jugoslavien. Operationen blev kritiserad för att ha tillfogat s.k. ?collateral damage? och vissa ickestatliga organisationer hävdade att brott mot krigets lagar begåtts.Specifika dokument, som reglerar luftkrigföring, har historiskt sett saknats. Detta har inneburit problem för bedömningar av enskilda fall.

Globala frågor i samhällskunskap A : Uppnås målen?
This thesis investigates how teachers in political science work with global issues in their teaching. It investigates the implementation within a specific area. Implementation is a problematic concept and in debate it is often accused of not working.This thesis finds out whether dissatisfaction exists among teachers when it comes to how municipal schools work with global issues.The investigation consists of three interviews made with teachers in political science, all from municipal upper secondary schools, in three different cities.The result shows that dissatisfaction exists among the teachers. Lack of time and lack of dialogue between the teachers and the principles are described as the main hindrances to reach the goals of the implementation. The implementation is however, in a broad outline, depicted positively..
Mobbning i förskolan : En studie om förskolepedagogers definitioner av begreppet mobbning
Bullying is something that is often times talked about in relation to school, in spite of that it's still something that is a very common problem. It is also rarely ever clearly defined, and is subject to a heap of different definitions. In order to prevent something, we must first understand it, and therefore define it. With that the purpose of this study is to examine swedish preschool-teachers definitions of bullying. How do they define bullying? Do their definitions differ from one another?The investigation was qualitative and used qualitative interview methods to interview four pre-school teachers about their deifnitions of bullying.
A risk analysis of moose close to roads
For many decades the increase in traffic volume, expansion of highways and infrastructure has lead to an increase of wildlife vehicle collisions which are unfortunately very common in many countries today. They cause great deal of material damage and even kill humans or wildlife. Measures in the form of warning signs, under- and overpasses and fencing have been implemented for a long time with the help of observation by hunters and collisions sites. However this study focuses on the moose?s perspective and the variables that, both spatially and temporally, could have an effect on why and when moose are close to certain types of roads.
Tumult i Texas - ett undersökande arbete om bildspråk och berättande
Thick skin in Texas - an investigation on storytelling and pictorial language. I took my starting point in a story about the cowboy Jaquin, who goes to the Tivoli, where he gets caught up in a dramatic adventure. I extracted three scenes from this story, and I experimented with whether it was possible to make the separate scenes tell their own story, in three separate drawings. Without depending on the frame story or on any kind of text. In this project I partly wanted to explore the possibilities of the drawing.
I strävan efter anti-estetik och musikalisk etik
In his master thesis, Johan Jutterström pursues an anti-aesthetic and ethic artistic process. He?s using mainly three different strategies; reasoning through text, composing for ensemble, and solo improvising on the saxophone. Through composing the piece for 12 musicians Trästolen, Jutterström tries to erase himself and his taste from the music. In that endeavor he looks to physics as a catalyst.
Filmiska landskap : film som representation, verktyg och handling i landskapsarkitektur
The title of the final thesis is Filmic landscapes ? film as representation, tool and practice in landscape architecture.
The aim of the final thesis is to investigate how film as a medium can be used to describe, interpret and manipulate the understanding of a place and its design. What kind of aspects of landscape architecture can film as a medium in a design-process emphasize or create? How can filming, as a self-standing act, contribute to the understanding of the landscape and a landscape-related design-process?
The thesis is divided into two parts, one theoretical part that consists of an essay, and one practical part that consists of a 11minute long filmic reflection of the ?Glass-houses?in Kosta, Sweden, created by the Swedish designer and architect Bruno Mathsson.
CISG eller nationell lag? : En jämförelse mellan artiklarna 4 och 7(2) i CISG
In 2009 transgendered persons were included in the Swedish law against discrimination. Prior to the inclusion a commission made an investigation of the necessity of such change in the law and how it could be designed. This essay focuses on the discourses regarding gender that appear in the law and the report written by the commission. Using theories by Judith Butler and discourse analysis inspired by Norman Fairclough it identifies two main discourses regarding gender: a two gender discourse and a queer discourse. The two discourses meet in the studied material in an antagonistic way, a conflict that is solved by separating the two and making one part of the law focus on gender and one on transgender.
Förbättring av U-värde i träkonstruktion för fönster med Aerogel
When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..
