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.

This thesis is done in cooperation with SWECO Energuide in Växjö. They have been assigned by SKB in Oskarshamn to renew their electrical power supply and the ancillary processing systems in their Central provisional storage of spent nuclear fuel, CLAB. Today in the CLAB facility, the spent fuel is cooled down with water pumps, driven by asynchronous induction motors, where the water is regulated by mechanical valves to the desired flow. After the upgrade, the engines will be powered by AC drives that can control the pumps by changing the rotational speed and thus change the water's cooling effect on the nuclear fuel. In this study, I investigated the interference AC drives causes the feeding network and how to go about averting them.

Flera städer och regioner har börjat arbeta tillsammans för att stärka sina gemensamma positioner och öppna nya möjligheter för företagen i regionen. Genom att etablera så kallade logistiknav kan samarbete mellan olika aktörer i regionen ske på nya villkor. Gävle-Borlängeregionen kommer till hösten 2011 att lansera MellanSveriges LogistikNav, som har som mål att bli etablerat som varumärke och stärka affärsmiljön i regionen. Vi fick i uppdrag av Mellansvenska Handelskammaren, som ligger bakom MellanSveriges LogistikNav att se närmare på ett antal frågeställningar angående logistiknav runt om i Sverige och förutsättningarna för att starta upp detta i denna region. Tillvägagångssättet som vi valde att använda i arbetet för att uppnå vårt syfte var att först gå igenom den teori som fanns kring logistiknav och lokaliseringskriterier.

Syftet med fo?ljande kvalitativa studie a?r att med hja?lp av intervjuer underso?ka la?rares arbete med och tankar om skolans va?rdegrund na?r det kommer till demokrati, fostran, ett ma?ngkulturellt samha?lle och ja?mlikhet. Fra?gesta?llningarna inkluderar a?ven en avsikt att studera hur undervisningen ga?r till, om denna enbart a?r planerad eller om de intervjuade la?rarna vittnar om icke planerade la?rsituationer. Metoden som anva?nds a?r semistrukturella intervjuer som sammansta?lls, transkriberas och analyseras genom att applicera Deweys teorier om intelligent action pa? resultatet.

Att vara välutbildad, social och intelligent räcker inte för att nå toppen, speciellt inte om du är kvinna, men Annika Falkengren är idag en av Sveriges mäktigaste personer inom näringslivet som Skandinaviska Enskilda Bankens VD, i en bransch dominerad av män. Eftersom de retoriska förmågorna och strategierna är väsentliga inom ledarskap ska jag i denna uppsats identifiera Annika Falkengrens kommunikationsstrategier i årets viktigaste tal inom banken, de som hålls vid de årliga bolagsstämmorna. .

In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

I uppsatsen undersöks om läsarens upplevelse av en litterär text i lättläst version skiljer sig från upplevelsen av originalversionen. Där undersöks också vilka bearbetningar som gjorts i den lättlästa versionen samt kopplingar mellan bearbetningar som gjorts och skillnaderna i läsarens upplevelse mellan versionerna.Som utgångspunkt för undersökningen ligger tidigare forskning kring läsares upplevelser och tolkning av litterära texter. En av utgångspunkterna för undersökningen av de bearbetningar som gjorts i den lättlästa versionen var begreppet adaptation, vilket redogörs för i forskningsöversikten.Denna studie utgår från två undersökningar, en analytisk och en empirisk undersökning. Den analytiska undersökningen visar att omfattande textbearbetning av typerna strykning, tillägg, utbyte och omstrukturering gjorts i den lättlästa versionen. Som utgångspunkt för den empiriska undersökningen ligger frågor som berör både innehållsmässiga och språkliga aspekter och som syftar till att undersöka läsarens upplevelse av berättelsen.

The globalization of today?s society has enabled consumers to acquire products and services from all over the world. Global organizations have the entire world as a playfield and offer products and services across markets. Regardless perception and transparency of the global market, consumers are still individuals. Consumers may have different perceptions and ideas about products, their functions and usage.

There have been changes in Earth?s climate system on both global and regional scale since the pre-industrial era and some of these changes are due to human activities such as the combustion of fossil fuels. This calls for the development of engines with a higher efficiency and less harmful emissions. One interesting concept is the Homogeneous Charge Compression Ignition (HCCI) engine, which has the advantages of potentially low emissions combined with high efficiency. However, HCCI with diesel fuel requires a relatively long fuel/air mixing time to ensure a "homogenous" charge.

The interest for functional strength training in golf has grown the last decade and scientists are always trying to find training stategies to improve the biomechanical aspects of the swing. Kinematic sequence contains a proximal-to-distal sequence order towards impact, and an effective kinematic sequence in the down swing begins with a rotation in the pelvis and follows by an activation in thorax, arms and club in the respective order. The rotational torques in the proximal segments wanders through the body and to the more distal segments to create an effective energy ? and power transfer at impact. The x-factor stretch is the seperation between the rotation in the pelvis and the thorax at the top of the back swing and at the beginning of the down swing.

The purpose of this bachelor degree thesis is to analyze technical issues associated with an implementation of a low sloping trash rack with narrow spacing. A hydropower plant in Umea?lven was used as a case study. The basis for the study was a model where trash racks were dimensioned for inclinations between 25 and 45 degrees. Corresponding head loss, durability and water speed through the rack were then determined for each inclination.

AbstractWe are facing a century of rapid change in climate, with significant challenges in managing the impact of changes in living conditions for plants and animals. We can already see the responses of species through changes in phenology and spatial distribution, which may change ecosystem structure and function, with subsequent effect on ecosystem services and biological diversity. In Sweden, between 2005 and 2010, the red-listed species has increased by 13 % and similar trends can be seen across the world, making it difficult to attain national and international environmental objectives of preserving biodiversity. One way to reduce the loss of biodiversity is to protect nature from exploitation by allocating valuable areas as nature reserves, but climate change affects protected areas just as much as other landscapes and therefore requires elaborate systems of protection to facilitate species' survival. The paper has examined  how the decisions and management plans for nature reserves in Sweden have been followed-up and whether they are climate adapted or not by examining 30 nature reserves, classified as newly formed (2012), recently revised (2009-2011) and older (1977-2007) reserves, and assessed what is in the decisions and management plans for follow-up, revision, long-term goals and documentation.

Syftet med denna uppsats är att visa hur maskulinitet gestaltas i filmtrilogin Härskarringen och att undersöka huruvida karaktärerna är nyskapande eller stereotypa. Härskarringen valdes ut i samband med en större undersökning bland manliga gymnasieelever. Vi använder oss av en kvalitativ analys av de tre filmerna. I Härskarringen presenteras en stereotyp bild av maskulinitet där typiska manliga karaktärsdrag är att vara ädel, fysiskt stark, modig, lojal, ödmjuk, potent, intelligent, beskyddande, respektingivande och med en stark vilja att kämpa för det rätta..
