In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.

Wetlands are important ecosystems and form habitat for both common and threatened species. In Sweden, as well in many other places on earth, there is a lack of wetlands. There is an expressed will to adjust this lack through restoration of wetlands with reduced function and through construction of new wetlands. Follow-ups and evaluations are important steps to optimize these actions. The wetland Vattenparken was constructed 1999 ? 2000 for treatment of surface water.

This qualitative study treats the construction and maintenance of balance between work and private life and how flexibility in the workplace is perceived. The study was conducted using semi-structured interviews and these have been conducted in five large companies around Gothenburg. The analysis and results are based on the phenomenographic method approach and the final results were four themes: Balance, Flexibility, Combining family and work and lifelong learning with related subcategories. The result shows that the construction and maintenance of balance between work and personal life is something that is tied to the indi-viduals and the current situation in life. Two of the most common strategies to maintain a dis-tinction proved to be planning as well as other activities, in order to move the focus away from the work.

The object of this examination project is to produce a method of work sampling at Rapid Granulator AB. The aim is to perform the method at the company and evaluate if it is executable. The study is delimited to the basic construction of the 45-series in the assembly hall.Preparations to produce the method of the work sampling resulted in definitions of activities, a form and a product tree. Several days were spent studying the assembling to learn and understand the entirety.The work sampling result showed a large amount of no value adding time that was used in the assembling. Some of the activities could be reduced and we observed some problems during the assembly process.

A protection helmet for young people (3-7 years) in winter environment has been developed in this thesis. The result is a concept proposal for development at STIGA Sports AB in Eskilstuna. This thesis work has been performed during 20 weeks, for a Master of Science in Product and Process development at Mälardalen University Eskilstuna Sweden in September 2009 to January 2010. The helmet is shown as a CAD model with detailed solutions to the outer shell, interior and adjustability (in sizes 50-56 cm) which are the three focused areas in the development. Also a physical model in scale 1:1 has been developed and is shown in this thesis work.To achieve the best result possible the process started with an analysis of the market and the product.

My own experiences as an upper secondary school teacher and the increase in research on masculinity in educational settings that occurred during the late 1990 emphasizing on the gender gap in achievement and grades is the point of departure for this thesis. The aim is to investigate how boys in upper secondary school are constituted and constitute themselves as motivated and achieving learning subjects. Another aim is to see what possibilities there are to form different teaching practices to create other possible positions for me and the pupils. The research questions are 1) How does boys´ construction of masculinity constitute how they see their own ability to be motivated and achieve in school 2) What significance do my shifting approaches and expectations on the pupils as well as teaching have on the boys constitution as learning subjects? To answer these questions I use a theoretical framework of feminist poststructuralist.

Construction accounts for about 35 percent of the total Swedish energy consumption and most of the energy is used by the large housing stock from the so-called ?Million program?. In the national action plan the government has put forward in energy efficiency. It is mentioned that existing buildings account for more than 90 percent of what is expected to be the housing stock within the coming 50 years. In order to meet environmental objectives its required that the existing stock be reviewed for energy efficiency. The goverment is now initiating a national framework with a budget of SEK 300 million Swedish crowns per year for five years, starting in 2010 to achieve the goal on energy efficient buildings. Energy efficiency of buildings in both new construction and above all within the existing stock are addressed.

The construction and use of buildings in the EU accounts for half of the EU?s extracted materials and energy consumptions, and a third of greenhouse gas emissions. In the past decade, the construction sector has responded to such concerns by focusing on post production energy efficiency. However, new findings indicate that upstream Construction processes influence emissions significantly ? necessitating a shift in focus to include material choices and building processes.

Outsourcing, förflyttning av funktioner till extern part som tidigare funnits i företaget, är ett fenomen som under de två senaste årtiondena har vuxit starkt i världen. Outsourcing har möjliggjort för företag att fokusera på sin kärnverksamhet och därmed erhålla konkurrensfördelar. Business Process Outsourcing är en kategori inom detta område, som innebär att företaget outsourcar hela eller delar av sin ekonomifunktion. Användandet av Business Process Outsourcing har ökat bland de svenska företagen under de senaste åren. Det finns mångtydiga förklaringar till denna framväxt, där en förklaring är att det är en trend.

This thesis has evaluated environmental classifications of projects and the lessons learned to explore what the possible ramifications of implementing this in the construction and infrastructure are. Companies today are looking to develop methods to demonstrate their environmental commitments, but there is an uncertainty regarding the contribution of environmental classifications in this aspect.The literature review presents the theory of environmental classification, which provides a general knowledge of its function. The empirical data is based on an analysis of existing classification methods and qualitative interviews. The analysis shows specific environmental classification system for the area of construction and infrastructure. CEEQUAL is currently the only environmental classification applicable to Swedish projects and therefore serves as the basis for the continued analysis.

Syftet med denna kvalitativa undersökning är att jag vill beskriva och analysera homosexuellas komma-ut-processer. Datainsamlingsmetoden som använts är intervjucitat med kvinnor från den skrivna litteraturen, Lesbisk identitet, Dubbelliv och Komma ut, samt livsvärldsbaserade temaintervjuer med tre av mina vänner. I intervjuerna har jag utgått från dessa olika teman; upptäckt, resans gång och dagsläge. Jag har även med ett par citat från egna erfarenheter.Mina teorier jag har använt mig av är, Fuchs Ebaughs Exitprocess, Pennebakers begrepp Disclosure och Inhibtion, jag har även använt mig av interaktion, roll- och stigma inom socialpsykologi. Jag kommer att göra ett försök till att beskriva och analysera dessa områden inom mitt ämne; komma-ut-process i sin helhet, Vad är det som påverkar kvinnornas agerande i en komma-ut-process och hur personer i det sociala nätverket involveras i en komma-ut-process.

Detta examensarbete utreder frågeställningen om den såkallade "olyckskorpen" ? alltså yrkesarbetaren som är inblandad i flertalet arbetsplatsolyckor ? verkligen existerar. Frågan är lite av kontroversiell typ och har diskuterats sedan 1940-talet, utan något avsevärt utslag eller dokumenterat alster.Samarbetspartner blev NCC Construction och två av deras stora arbetsplatser i Stockholmsområdet valdes som mätfält; Söderby samt Frösunda.Undersökningen baserades på datainhämtning genom enkätformular till yrkesarbetare och ledning på de utvalda arbetsplatserna, genom erfarenhetsinhämtning från platschefer och lagbasar inom NCCs organisation samt från YTH-studenter på byggprogrammet. Författarnas egen erfarenhet från branschen har också vägts in i bearbetningen.Resultatet gav ingen olyckskorp att sätta fingret på, men en indikation från samtliga håll att egenskaper som kan knytas till olyckskorpen förekommer i branschen. Detta gav upphov till en teoretisk modell att användas för att ringa in olyckskorpar på individuell nivå i en vidare undersökning..

This degree project handles acoustic measurements of the heat pump EcoAir 107, made by Enertech CTC AB. The sound from the three sound sources of the heat pump, fan, compressor and four way valve, have been measured to find out how they affect the total sound level of the product.Measures to attenuate the sound level have been developed and tested. By comparing these with the sound of the heat pump, in its original state, we have found out the measures which have best effects.The best attenuating measures came to be: taped openings and holes around the compressor space, isolating the top and the bottom of the whole construction, support of the fan bottom part and shielding of the sound source with a screen at a distance of 110 mmThese measures have been tested together and an average attenuation of the total sound level with 3,9 dB have been accomplished. In the front of the fan where the continuous sound is the strongest, the attenuation was 4,7 dB.This project is meant to be used as a guide by Enertech CTC AB:s during their future developing process..
