With growing economies and better living standards in many parts of the world today, there is a need of expanding the capacity of generating electricity. The alternatives for renewable energy technologies are not fully developed and have still some problems to conquer.The company Minesto has developed a technology that is called Deep Green. It is designed to gain electricity from tidal currents. Deep Green works in a similar way as a kite that is attached to the seafloor with a moving wire. It contains of a wing that moves due to the water current.

AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectors’ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the company’s products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the company’s products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTA’s demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.

Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.

Va?rlden sta?r info?r en av de kanske sto?rsta utmaningarna na?gonsin, att begra?nsa ma?ngden va?xthusgaser i atmosfa?ren till ha?llbara niva?er. Fo?r att uppna? detta ma?ste alla delar av samha?llet effektivisera och begra?nsa sin energi och resursanva?ndning.I detta kandidatexamensarbete har ett av A?sbacka Tra?dga?rds va?xthus i So?derhamn studerats fo?r att underso?ka mo?jliga investeringar till reduktion av den energianva?ndning som idag ra?der. De energireducerande a?tga?rderna har simulerats med programvaran IDA ICE 4.6 och da?refter analyserats och ja?mfo?rts med varandra.

Uppsatsens syfte var att genom en kvalitativ undersökning utröna ensamkommande barns förväntningar före flykten, deras tankar om språk, språkinlärning och huruvida dessa förväntningar uppfylls eller förändras efter permanent uppehållstillstånd i Sverige samt om tankarna om språk förändrats. De sex pojkar som intervjuas i studien kommer från Afghanistan, Somalia och Kamerun och hade olika livserfarenheter innan flykten. Uppsatsen visar att förväntningarna förändrades i och med det faktum att de fick lov att börja skolan när de kommit till Sverige något som de inte hade kunnat föreställa sig. Några informanter, vilka var analfabeter, har även fått en för dem helt ny identitet i den bemärkelsen att de nu mera ser sig själva som läsande och skrivande människor vilket de inte hade kunnat föreställa sig tidigare. De som inte gått i skolan tidigare i sina hemländer och inte kan något annat språk än sitt modersmål tycker att det är besvärligt att lära sig svenska, det känns märkligt i munnen att uttala ord och meningar på svenska.

Syftet med uppsatsen är att undersöka den diskurs som följde i svensk media efter migrationsverkets beslut att ge syriska flyktingar permanent uppehållstillstånd.Metoden som vi har utgått ifrån är kritisk diskursanalys och innehållsanalys. Som data har vi valt ut tolv artiklar och två TV-program.Resultatet visar att media äger den makt som gör att de får avgöra hur ett sådant beslut ska presenteras och diskuteras. Resultatet visar även att media använder idag en annorlunda diskurs jämfört med 1980 och 1990 talet.Media kan med sin makt avgöra vem som ska/inte ska uttrycka sig. En ?Vi? och ?De? skapas av media som skiljer mellan den etablerade och den oetablerade i samhället.

Offshoreindustrin på Nordsjön sysselsätter ett stort antal offshorefartyg med olika uppdrag för att stödja produktionen av olja och gas. Prospektering av nya oljefyndigheter, bogsering av installationer och att förse installationer med förnödenheter är några av de uppgifter offshorefartyg utför.För att genomföra arbetsuppgifter säkert, använder offshorefartyg och installationer sig av North West European Area Guidelines. Riktlinjer för hur arbeten skall utföras säkert och för att undvika olyckor som kan skada både människa, miljö och ekonomi.Kollisioner mellan offshorefartyg och installationer sker ändå, med varierande konsekvenser. Syftet med detta examensarbete är att ta reda på vad som sker på bryggan, ombord på ett offshorefartyg när det skall utföra arbete intill en installation. Rapporten är tänkt att ligga till grund för framtida arbeten som syftar till att öka säkerheten inom branschen.Som datainsamlingsmetod har gruppintervjuer utformade som fokusgrupper använts.

Background: Because of the high unhealthy rates among women in the com-mune a project to reduce it have begun. For this reason we have been given the mission from the commune of Sotenäs to study the character of these women's health. Objective: To study the health among permanent employed women in the commune of Sotenäs. Method: Quantitative method. The data have been collected through question-naire survey.

According to the Employment Protection Act, the permanent employment is the main condition of employment in Sweden. Nevertheless, nowadays a large number of employers choose to apply other conditions of employment than the permanent employment in their businesses. The rapid technical development and the demands for shorter perspective investment in companies on the Swedish labour market have started the requirement for a more flexible workforce. On-call employment is one of the conditions of employment that is increasing the most. This condition of employment is adjusted by the parties on the labour market.

In many regulated rivers, authorities have stocked hatchery salmon to compensate for loss of wild populations. However, hatchery fish have not always behaved as wild fish do, and stocking them has not always fully compensated for the loss of wild fish. The purpose of this study was to compare swimming behaviour in the river before spawning, the choice of spawning areas and body size between wild and hatchery-reared salmon in the river Klarälven. Salmon behaviour in the river before spawning was analyzed using radio telemetry. The salmon were caught at Forshaga power plant, radio-tagged and returned to Klarälven at Ekshärad, 107 km from the river?s mouth.
