Background: The most energy efficient houses today are so called passive houses. These houses achieve high energy-efficiency partly by having well insulated walls. U-value describes the amount of heat transfered through a building element, the more insulation, the smaller U-value. A typical passive house wall have a U-value of 0.10 W/m2,°C. The passive houses are primarily made as small family houses and not as a block of apartments.

This thesis, designed as a case study, is about complications concerning conservation of a decorative oil paint on lime plaster from the drawing-room in Mostorp castle sited in the county of Halland in south-west of Sweden. The building was built 1878-80 with an exterior of granite. The interior walls were made of clay bricks, lime mortar and lime plaster. The oil paint is applied to a layer of putty. The combination of different materials, which are organic and inorganic, affects the movement caused by internal and external stress.

I föreliggande studie undersöks hur ett undervisningsupplägg baserat på flipped classroom påverkar resultatet i en matematikklass på det naturvetenskapliga programmet, samt hur eleverna förhåller sig till ett sådant undervisningsupplägg.Klassen undervisades av samma lärare, men med olika undervisningsupplägg, i tre olika matematikkurser: Traditionell undervisning med klassrumsbaserade genomgångar i Ma 1c; inverterad undervisning i Ma 2c där eleverna före lektionstillfället tog del av en videogenomgång, för att frigöra tid för uppgiftslösning i klassrummet; inverterad undervisning i Ma 3c med tillägget att man i klassrummet använde sig av undervisnings­verktyget peer instruction.En enkät gjordes angående elevernas attityder till de olika undervisningsuppläggen. Vidare gjordes en jämförelse av klassens resultat på de nationella proven med resultaten i riket, samt med resultaten för en elevgrupp som undervisats traditionellt.Enkätsvaren visar att eleverna var mycket nöjda med flipped classroom, och att majoriteten ansåg att de lärde sig mer med flipped-classroom-baserad undervisning än med traditionell undervisning. Detta gäller elever på alla betygs­nivåer; elever med såväl som utan tillgång till matematik­hjälp hemma; pojkar såväl flickor. Elevernas inställning till peer instruction var mera splittrad.Jämförelsen av resultat på de nationella proven visar en tydlig nedgång i elevernas prestation mellan Ma 1c och Ma 3c. Den största delen av nedgången skedde mellan Ma 1c och Ma 2c, dvs.

The objectives of this experimental study were to investigate if a strategic method to supply loose housed sows with large quantities of straw 2 days before expected farrowing and if the sow?s body condition had any effect on the occurrence of shoulder lesions 5 weeks after farrowing. Data came from a study conducted on four commercial piglet-producing farms in southwest Sweden between March and December 2009. At each farm one batch of sows was followed during two consecutive lactations. The sows were randomly assigned to two different treatment groups and the sows that remained in the batch during the second lactation switched treatment group.

Aim Developmental Coordination Disorder Questionnaire 2007 (DCDQ'07) is an international survey tool based on parents' estimation of their child's motor coordination skills. The purpose of this study was to investigate the validity of a Swedish version of DCDQ'07 by finding out how the classification of Developmental Coordination Disorder (DCD) via DCDQ'07 is consistent with the classification of DCD via the motor impairment test, Movement ABC.MethodIn the context of a larger study, a Swedish translated version of the parent survey DCDQ'07 were sent to 4000 randomly selected families with children aged 8 - 10 years in Stockholm County. The classifications "DCD" or "NOT DCD" with cut-off values ??of 56 (9 years) and 57 (10 years) were applied. Forty families were selected from 410 registered responses.

Today dairy farmers in Sweden are obligated to have lights turned on during night time in addition to the mandatory daylight inlet. This presents a cost for the production but many argue that it can be economically beneficial, especially in loose housing of dairy cows. In loose housing and even more so in herds with automatic milking, well functioning cow traffic during all hours of the day is crucial to optimise production. In order to keep the cow traffic flowing, lights may be an important management tool. It is also perceived among farmers with tied up stall that night light decreases the incidents of cows accidental stepping on their own or neighbours udders.

AbstractThe project "Sound and Play" have been implemented in collaboration with the toy company BRIO in Malmo. The purpose of the project was to examine whether and how BRIO in the future could develop toys around sound for Toddlers.The problem formulations that would be answered after completion of the project was "How could BRIO broaden its product range with the help of audio toys?", "How can you combine toys and sounds in an interesting way for children?", "How do you create a toy with sound that is fun for the child, but not annoying for parents?". Currently BRIO only has two toys with sound in this age group.The expression of the toy was going to be a mix of classic and cool and the overall feeling of the toy was going to be explorative and arouse curiosity in the child. This feeling would be communicated through simplicity and joy.

Promoters are genetic elements that facilitate the transcription of a gene and they have been found in front of non-coding RNA (ncRNA) genes in different organ-isms, e.g. the model plant Arabidopsis thaliana. A similar element, DUSE, has been found in front of ncRNAs in the social amoeba Dictyostelium discoideum and a part of this project has been to analyze the function of this putative promoter element through cloning and expression studies. A construct to analyze the func-tion of DUSE was successfully designed and introduced into D. discoideum but full expression studies were not finished because of shortage of time.

IRB 340, Flexpicker is an industrial robot used for sorting, packaging and the handling of details up to two kg. The Flexpicker is a delta robot, meaning that it with three arms controls a triangular plate, swivel, in a work area shaped like a cylinder. Joints using plain bearings connect the arms.The plain bearing in use today consists of a plastic ring which slides against a hard anodized joint ball. Despite the fact that the plastic contain friction-lowering additives, the bearing needs to be lubricated to prevent noise. Because the robot is used in food and drug handling environments, where the demands on hygiene are set very high, the robot is often washed.

The purpose of this study is to achieve an understanding of how a CE- marking process is conducted and to identify the relevant factors that must be considered in such a process. We have conducted our study at Lo?vhults Svets & Smide AB (Lo?vhults) in Skruv, Sma?land Sweden, which are manufacturing brackets for small covering constructions.To understand how a CE-marking process is conducted several documents and provisions have been reviewed to achieve a basic understanding and insight of the subject. It thus led to that guideline ETAG 015 were studied and the factors to be considered in the CE-marking of brackets were identified. Together with Jan-A?ke Johansson at Lo?vhults we agreed on four different brackets to investigate for a potential CE-marking.

Denna uppsats handlar om vilka olika kunskapsformer som testas i skriftliga prov i geografi på gymnasiet och om hur detta förhåller sig till betygskriterierna. För att besvara detta har tio geografilärares prov analyserats med hjälp av Blooms reviderade taxonomi. Tidigare forskning visar att prov i SO-ämnen nästan enbart testar minneskunskaper. Denna studie bekräftar delvis detta då de analyserade proven domineras av frågor som testar att minnas. Samtidigt finns det en variation i vilka kunskapsformer som testas.

Chlamydia is a sexually transmitted infection. The infection rates have increased in the last decade. During 2008 the trend rates declined in all counties and regions in Sweden. Chlamydia infections have a geographical spatial pattern differences. This is seen from the national surveillance data report from the Swedish Institute for infectious disease control (SMI).

This project is implemented as a thesis at the Royal Institute of Technology in the master?s degree program Integrated Product Design and Industrial Design Engineering. The project has involved development and efficiency of a free starter package for expectant parents with useful content consisting of useful products for both before and after childbirth. Areas that have been investigated include packaging development, service design and appropriate content for the package.During the work, theory about packaging design, materials, manufacturing techniques and logistics have been processed to base the further work on. The project process has involved competitor analysis and interviews with store owners and customer surveys, that have been conducted to identify areas for improvement of the current solution.

Syftet med denna studie är att i en kommun söder om Stockholm undersöka det eventuella stöd som elever i år 1-5 med läs- och skrivsvårigheter och dyslexi erhåller. Studien är baserad på en enkät som skickats till samtliga speciallärare och specialpedagoger i den aktuella kommunen. En telefonintervju med en person på kommunnivå genomfördes för att komplettera undersökningens resultat. Studien visar att alla skolor utom en har speciallärare och specialpedagoger till elevernas förfogande. Rektorn på varje skola ansvarar för stödundervisningen, då kommunen sedan en tid decentraliserat ansvaret för detta.
