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.

This is a study based on discourse theory in purpose to examine the border-politics ofthe EU. Since the EU step by step has developed into an area of free movement on capital, people and services, the external frontiers have been given prioritiy on the political scene. Development in recent years have put questions of foreign- and security politics on a supranational level, meaning that the EU-member states in a wider range now cooperate in these political areas.To handle the increasing ammount of (illegal) migration to the EU an independet agency, Frontex,was established 2005 in favour of coordinating the Member States in issues regarding bordersecurity. The focal point of this study is to critically examine the identity of Frontex by using Becks theory of risk combined with the theory of governmentality. By doing so I seek to highlight the relation between Frontex and the EU and also that of Frontex mission in relation to illegal immigration.

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.

Denna uppsats behandlar en undersökning som gjordes efter det att en gymnasieskola i Örebro migrerat från Microsoft Office till Open Office. I studien undersöktes vilka för och nackdelar som lärare upplevde efter migrationen samt vilka problem som uppstod då öppen mjukvara används i en miljö som är dominerad av proprietär mjukvara.Det tillvägagångssätt vi valt är en metodtriangulering där vi samlat in data med hjälp av tre olika insamlingsmetoder, en litteraturstudie, kvalitativa intervjuer och en kvantitativ enkät. Dessa insamlingsmetoder utformades så att litteraturstudien var av bredare karaktär och leder till att intervjuerna blir av mer specifik karaktär som i sin tur ger oss kvantitativa frågor till enkäten.Det vi funnit under arbetets gång är att migrationen lett till interoperabilitetsproblem med existerande proprietära system och även att filer tolkats olika av de båda kontorspaketen. Lärarna såg större skillnader mellan de båda kontorspaketen är vad skolan och kommunen förutsett och tyckte att de mer avancerade funktionerna är svårare att använda i Open Office vi har även sett en efterfrågan utbildning..

Denna studie fokuserar på relationen mellan migration, identitet och skrivande i en svensk-turkisk migrationskontext. Abdullah Yücel var en av de första som emigrerade till Sverige 1965 från Kulu i Turkiet och blev en nyckelperson bland kuluturkarna i Sverige, bland annat genom sina dikter. Genom en diskursanalys av Yücels poesi är studiens syfte att diskursivt analysera migrationens konsekvenser för identitetsskapandet i den svensk-turkiska migrationskontexten. Teoretisk utgångspunkt är framför allt Parks begrepp ?the marginal man?.

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.

Syftet med denna studie är att öka kunskapen om diakoners arbete med papperslösa. I Sverige finns det 10 000-tals papperslösa som befinner sig här efter att undanhållit sig utvisningsbeslut, smugglats in som traffickingoffer eller strävar efter att arbeta ihop inkomster att skicka till hemlandet. Med en kvalitativ ansats har jag intervjuat sex stycken diakoner som arbetar i Svenska kyrkan i Stockholm, och som alla möter och erbjuder socialt stöd till papperslösa. Resultatet har jag analyserat utifrån teori om ekologiskt perspektiv på socialt arbete med flyktingar och migranter, samt teorier om värdegrunder i socialt arbete. Resultatet visar att diakonerna fokuserar på det sociala arbetet på mikronivå, men att viss samverkan på mesonivå förekommer.

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.

Bakgrund: Den ?kade migrationen g?r att sjuksk?terskor m?ter fler migranter med olika kulturella syner p? psykisk oh?lsa. Psykosociala p?frestningar ?kar hos migranter risken f?r att drabbas av psykisk oh?lsa och vid otillr?cklig kunskap leder detta till bristande bem?tande vid v?rd av migranter. Syfte: Syftet ?r att beskriva sjuksk?terskors erfarenhet av att v?rda migranter med psykisk oh?lsa fr?n annan kulturell bakgrund.

In published studies it is found that the fuel consumption on a forwarder is relatively constant, on time basis. A certain variation between different sizes of forwarders occurs as well as between different working elements. The aim of the study was to establish a forwarders comparatively fuel consumption when driving on road and in the terrain, loaded and unloaded, with high and low gear and with high and low speed as well as with hydrostatic and hydrodynamic transmission. A hypothesis was that low rpm gives lower fuel consumption on distance basic, at all trials. The test driving was made with a Hemek 750 which is a three geared hydrostatic machine and with a Hemek 700 which is a hydrodynamic machine with six gears.

Aren?t you tired of never finding stuff? Take a bits as example, do you store these lose in your toolbox or carpenter belt? What if you could have it all accessible and assembled in a tool, always at arm?s reach?Today bits are used together with electric screwdrivers and handheld screwdrivers in a greater spread. For these different types of storage, from pure storage boxes to complex tools with storage built in, exist. The professional craftsmen commonly use some kind of box where the bits can be stored. Even so they tend to store their bits loose in a carpenter belt or toolbox, since they want the speed and accessibility of carpenter belt over the storage box?s tidiness.The project was started in the fall of 2010 and a referents group was early put together to ensure that the developed product became as user-friendly and attractive as possible.

The economic growth in Ireland, during the 1990s, lead to changing migration patterns. Ireland became a destination country for immigrants instead of an emigration country. Before 2004 people who were born on the island of Ireland had a constitutional right to Irish citizenship. This right was removed after a referendum in 2004.National identity is a sense of community constructed through common history and defines who belongs to the nation. The purpose of this thesis is to do a critical discourse analysis of the debate in media before the referendum.The analysis was done on texts from The Irish Times, one of the major newspapers in Ireland.
