WesDyne TRC AB is a fully owned subsidiary of the global WestinghouseElectric Corporation. WesDyne is a world leader in non-invasive methods for theinspection of nuclear power plants. One of the inspection platforms used to scanfor defects in and around the welds in the reactor vessel is called the T-crawler.The T-crawler operates under water in a radioactive environment by stepping onthe vessel (reactor tank) inner wall using suction cups. The environment is harshand many traditional positioning sensors are not suitable for implementation. Thisthesis investigates the possibility to use a gyroscope and a pressure sensor tocreate an alternative and independent positioning system.

I detta examensarbete studeras kommande energikrav för byggnader i Sverige och i synnerhet kraven påspecifik energianvändning. Detta mot bakgrund av EU-kommissionens och EU-parlamentets direktiv,EPBD2, om nära nollenergibyggnader 2020. Därefter bearbetas ett förslag på en nyytterväggskonstruktion som med lägre U-värde än den befintliga ytterväggen ska sänkaFiskarhedenvillans olika hustypers specifika energianvändning. Syftet med sänkningen är att möjliggöraför Fiskarhedenvillan att uppfylla de kommande energikraven.Det är många parametrar som måste uppfyllas och det nya ytterväggsförslaget analyseras förutom urenergisynpunkt även med hänsyn till statik, fukt och kostnad. Beräkningar för statik och specifikenergianvändning har gjorts för ett referenshus.Resultatet av att byta ut den befintliga ytterväggskonstruktionen mot det framarbetade förslaget medca 33 % lägre U-värde gav endast en sänkning med ca 6 % av den specifika energianvändningen.

Rapporten innehåller inledningsvis en faktadel med allmän information kring temperatursprickor i betong. Här presenteras bl a uppkomsten av fenomenet, vilka typer av sprickor som förekommer och vad ett tvång är. Tanken är att ge läsaren tillräcklig kunskap för att kunna förstå sig på de övriga delarna i rapporten.Resultatet och det huvudsakliga arbetet redovisas i form av tabeller med tillhörande illustrationer där det går att utläsa vilken sprickrisk som förekommer vid flera specifika fall och vilken åtgärd som bör vidtas för att eliminera sprickrisken. Som konstruktör kan du med din egen indata, dvs. dimensioner och temperaturer, följa tabellen och finna resultatet för ditt specifika fall.

This thesis aims to illustrate how environmental impact can be reduced, through the use of lean concrete. It also illustrates how environmental data can be applied to a house through implementation with BIM. In this study a unique concrete structure developed by Swedish Cement and Concrete Research Institute is assessed for environmental impact, by calculating the carbon dioxide equivalents using LCA methodology. The construction is a sandwich element where the concrete is made ??up of three layers.

AbstractHeadline To communicate the environment, ?Rarely a paper on the wall?, a study about communication strategies when it comes to internalize a policy in two secondary schools.Number of pages 42 (61 including enclosures)Author Fanny PerssonTutor Peder Hård af SegerstadCourse Media and communication CPeriod Autumn 2007/spring 2008University Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/aim The purpose of this work was to see what channels of communication are to prefer when working with secondary school pupils, more concrete when speaking about the environment, about the profile of the school and democracy among the pupils.Material/method I am going to visit two secondary schools in the middle of Sweden, one that has an environment certification, and the other one is a regular secondary school. To answer these questions I am going to interview totally four teachers, two from each school, and 12 pupils from each school divided into two groups per school.Main results One of the main results was that the pupils prefer to mix the tutoring for a better way to learn. Another result was that they see their teachers as paragons and that it is more important what the teachers do than what they say.Keywords Environment, Communication, Environment Certifikation, Secondary school, Karl Weick, Communication theory, Understanding, Internalize, Identification, Profile.

Många byggnader är idag fuktskadade. Fuktskador uppstår på så väl nya som gamla byggnader. Idag provtrycker man hus för att få ett värde på dess täthet, men många hus som klarar täthetskraven drabbas ändå av fuktskador. Detta beror på att otätheterna är lokala på en eller flera delar av klimatskalet bortsett från otätheter vid anslutningar.  En studie har gjorts på två väggtyper; en standardvägg och en passivhusvägg.

Williams, E. 2003 Radiologic sign of lung oedema in the dog and cat. To determine if the descriptions of lung oedema in the literature accurately describe the presence and frequency of radiologic signs, thoracic radiographs of 55 dogs with mitral regurgitation due to endocardiosis (ME), 46 dogs with dilated cardiomyopathy (DCM), 9 dogs with hunting oedema, and 20 cats with hypertrophic cardiomyopathy (HCM) were analysed. The location, type (diffuse or patchy, without or with air bronchograms) and presence of pleural oedema, bronchial wall thickening, widened pulmonary veins, and heart enlargement with subjectively and by the VHS measurement, were determined, and analysed by chi squared test with respect to disease. The dogs nearly always had diffuse oedema, whereas 35% of the cats had a patchy pattern, which agreed with the literature. The common occurrence of cranioventral and caudioventral oedema in heart failure was not described.

The present project was initiated with the aim to create pattern modules for use in public environments. My intention was to let the properties, of the specific materials used, have a marked influence on the realisation of the final form. I also wanted to find a material, which is suitable from the perspective of sustainabilityand possibilities to create modules from it. The work was initiated with a study of some candidate materials and many sketches before I finally made my choice. My decision was clear after a visit to the company Glasfabriken inKalmar.

Tile covered bathrooms require a wellexecuted waterproofing in order toprotect the underlying construction frommoisture. Länsforsakringar Uppsala paysannually out millions in insurance fordamages related to poor waterproofedbathrooms. In recent years, SP (SwedishNational Testing and Research Institute)investigated and researchedwaterproofing products, resulting ingreater shortcomings of product defectsthan expected.This report raises the problemsconcerning waterproofing and discusseswhy they occur. By studying productinstructions and insurance cases anddamage reports provided byLänsforsakringar, the most commonproblems concerning bathroomwaterproofing where concluded. Animportant part of the report was tofind out the actual cause to whywaterproofing damages occur.The results of the survey indicate thata common cause of water damage usuallyis related to poor productinstallations.

Stone walls in agricultural land are incorporated in the general protection of biotopes. They are protected because they provide a habitat for endangered species. Therefore it is illegal to carry out proceedings in an area that is included in the protection of biotopes. In order to do that, exemption is needed which can only be granted if there are special reasons. The essay stipulates what these special reasons are.In an exemption errand the interest for nature conservation must be weighed against a public or a private interest.

Today's urban centers become denser, which contributes to higher demands on sound and noise. It is therefore highly relevant to build homes with good sound environment while maintaining living space. This thesis aimed to reduce the current concrete walls and see how the mass law affects the reduction index value and flanking transmissions. Handmade calculations were calculated according to the Swedish standard SS-EN 21354-1, where only air sound was calculated.Calculations we­­­re performed on wall elements with different weights and thicknesses, and compared with results from Bastian.In Bastian calculations of flanking transmissions were also made, this was made to see the impact of the flanking transmission when changing the mass per unit area. Mass law's impact was examined by flanking transmission and the result shows that they are not affected as long as the ratio between the thickness and the density remains the same.A questionnaire survey was conducted to determine the actual sound experience; this questionnaire was conducted on three concrete buildings in Växjö.

The purpose of this thesis is to investigate if vacuum insulation panels are a competitive alternative to traditional insulation.Vacuum insulation has been used as insulation in buildings in Germany and Switzerland for a few years. In Sweden the high-performance insulation material is mainly used in refrigerators, freezers and vacuum thermoses. The development is proceeding well and vacuum insulation is becoming more common in the construction industry. Since it is a relatively unexplored material on the market there are many flaws and problems with the material.The questions we have chosen to answer in this report include an increased knowledge of vacuum insulation, various problems that may arise when handling/installation and the pros and cons of vacuum insulation compared to standard traditional insulation.The methods we have chosen to use in this report is a literature study, interviews with various suppliers and manufactures and calculations to show the differences between traditional and vacuum insulation. Vacuum insulation is 5-10 times better insulation than standard traditional mineral wool insulation, mainly at the beginning of its lifetime.Vacuum insulation panels (VIP) have a service life of approximately 50 years, whereas traditional insulation has a service life of approximately 100 years.

This thesis within the field of Integrated Product development at the Royal Insitute ofTechnology, performed at Primary Development Dishcare at AB Electrolux, is supposed to finda solution to enhance the hygiene inside an Electrolux dishwasher. The outcomes of this thesisare functional prototypes to evaluate the efficiency of disinfection by the use of Ultra VioletLight and Ozone.The thesis has followed Electrolux Primary Development process, with delivarables andcheckpoints.Ultra violett light with a wavelength of around 264 nm penetrates through the cell wall ofbacteria and micro organisms and causes a molecular rearrangement of the cells DNA. Thisprevent the bacteria from reproducing and it is considered dead. Commonly used UV-C lampstransmits the wavelength 254 nm which is very close to the optimum for germicidal action.A competitive brand have reacently launched a dishwasher claiming to achieve greaterdisinfection with an UV feature. This dishwasher was tested during the thesis and proven tohave a very low effect on the hygienic result.Two prototypes were devolped and tested for UV disinfection of dishware.
