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.

Syftet: Syftet med denna uppsats var att se hur Nordiska Afrikainstitutet använder sig av sociala medier och hur de tillämpar den information som organisationen kommunicerat via de sociala medierna.Teoretisk ram: Uppsatsen utgår ifrån teorier som ger överblick i hur traditionella och moderna kommunikationsredskap fungerar. Därutöver har ett analytiskt instrument använts som kartlägger kommunikationsprocesser i organisationer samt hur dessa tar tillvara på ny kunskap. Den teoretiska referensram består av följande teorier: Media Richness modellen samt de två artiklarna On using organizational knowledge capabilities to assist organizational learning samt Virtual worlds as platforms for communities of pratices från antologin Knowledge management and organizational learning.Metod: Uppsatsen bygger på en kvalitativ metod. Det empiriska materialet har samlats in genom respondentintervjuer, dessa bestod av telefonintervjuer samt epostkorrespondens. För att urskilja respondenterna har ett snöbollsurval använts. Intervjuerna har därefter analyserats utifrån den teoretiska referensramen.Resultat: Resultatet av undersökningen visar att både traditionella och sociala medier används vid institutet där de traditionella medierna anses trovärdiga men inte alltid flexibla. De sociala medier som används är Facebook, Twitter och institutets egna forum kallat NAI-forum.

The aim of this study has been to describe the ongoing region enlargement process in the region Mälardalen, located in the east part of Sweden, and to investigate how this process can affect the local level. The study is especially orientated on public communications and accessibility. The intention has also been to examine how the local accessibility can affect the re-gional development in Mälardalen. The local investigation object that has been chosen for this research is the city Strängnäs, situated in the province of Södermanland. The city of Strängnäs and the cities in it?s near geographic surroundings has been the benchmark for this casestudy, in which the local accessibility with public transportation has been investigated.

The limit for mercury in fish, set by health authorities, is exceeded in about half of the lakes in Sweden. Methyl mercury (MeHg) is the most toxic form of mercury and accumulates in fish. Therefore transformation of inorganic mercury (Hg) to methylmercury (MeHg) is an important process that we need to understand in order to possibly counteract the negative effects of mercury in the environment. The seasonal dynamics of mercury biogeochemistry is likely of great importance for the accumulation of MeHg in the aquatic food web. In thesis the chemical speciation and transformations of Hg and MeHg in bottom waters and sediments is followed in Ängessjön, a small lake located on the east coast in the middle of Sweden. The lake is not directly affected by any industrial pollution and concentrations of Hg in the sediment reflect the atmospheric deposition in this area, as well as processes taking place along the hydrological pathways from soil to lake. Samples from sediment, bottom- and streamwater were collected in average every second month during the period Feb.

The demand for animal products has increased in the last decades, especially for poultry and pork. Pork production has increased drastically globally, and also in Uganda. Thirty-one percent of Uganda´s population lives in poverty. Pig production is believed to play a crucial role in poverty alleviation, because of the ability to convert low quality feed into high quality protein together with high reproductive potential. African swine fever (ASF) is a lethal disease of domestic pigs often characterized by haemorrhagic fever and with mortality rates up to 100%. The disease is endemic in most sub-Saharan countries and since 2007 in the Russian Federation and Caucasus area.

This paper is an analysis of the novel Season of Migration to The North by Tayeb Salih. Season of Migration to The North was first published in 1967 and it is the most accomplished among several works in modern Arabic literature.I shall focus on one of the two major characters, Mustafa Said, a young Sudanese student whose brilliant career at school in Sudan and Cairo eventually brings him to England; he has a successful academic career in England as a lecturer at the University of London.One of the major themes of the novel is the confrontation between Mustafa Said and England, which in other terms is described as the confrontation between East and West. The conflict is rooted in colonialism. Mustafa Said?s native country, Sudan, was a British colony when the story takes place.

Namibia, southern Africa, suffers from an energy shortage and is therefore facing severalchallenging problems. The use of firewood as fuel for cooking is common in the whole countryand has negative consequences for health and the environment. This work have focused ondeveloping a solar baking oven, calledSunbaker, adapted for Namibian families needs forbaking. The development was based on classic solar cooking limitations, specific needs forNamibia and to have a feasible manufacturability.The project started with a theoretical study in Sweden where different solar cookers, informationregarding Namibia, technical aspects and end user aspects were studied. To assess the need for asolar baking oven aMinor Field Study took place in Namibia during eight weeks in July toSeptember 2009 and resulted in a product design specification.

Interaktioner mellan vilda herbivorer och nötboskap är väldigt komplexa. Bland nackdelarna väger överföring av sjukdomar tyngst. Uppskattningsvis har cirka 70 % av alla sjukdomar hos boskap (inklusive zoonoser) som uppkommit på senare tid sitt ursprung hos vilda djur. Sjukdomar kan spridas via direkta kontakter eller indirekta interaktioner (luft, kroppsvätskor, avföring, kött eller mjölk) mellan vilda djur och boskap. Några exempel på sådana sjukdomar är: East Coast Fever, Corridor disease, January disease, katarralfeber, trypanosomos samt mul- och klövsjuka.

Nature conservation issues are often complex and difficult to handle. Different actors andinterests are involved and it is generally agreed that constructive interaction is a crucialpart of dealing with these issues. According the theory which forms the basis of this thesis,conflict is defined as social interaction during which the actors trust in the interaction isdecreasing. Signs of conflict and diminished trust in the interaction are that these actorsmake attempts to change the situation and some of these attempts can lead to increasedconflict.The aim of this thesis is to describe the social interaction that takes place when peoplemove from conflict to dialogue. A qualitative case study of a nature conservation issue inÖstra Vätterbranterna, an area east of Lake Vättern, is presented.

In modern society globalisation is a fact within all industries, the textile industry included. Due to improvement in areas such as logistics and communication international trade have developed fast. As changes occur rapidly on the global market and companies must adjust and revise their processes in order to stay competitive.Because of the global price reduction consumers around the world expect low-price products, which mean that the companies have to find new ways to produce in a cost-efficient way. To maximize profit most of the textile production is situated in low-cost countries due to its labour-intensive character. It is crucial for fashion companies to allocate their activities in their value-chain effectively in order to reduce lead-times.

Bakgrunden till denna uppsats är att tidigare forskning visat att elever läser annorlunda om det finns uppgifter kopplat till läsningen, vilket kan göra att det inte är texten som står i fokus. Tidigare forskning har också visat att tonåringar inte läser lika mycket som yngre gör, samt att det är annat de söker och vill identifiera sig med i texten, de vill ha en utmaning och få möjlighet att ompröva sina föreställningar. Syftet med uppsatsen är att undersöka gymnasier elever på teoretiskt inriktade programs inställning till skönlitteratur både i och utanför skolan för att ta reda på vilken roll sammanhang, plats, miljö och tidigare erfarenheter har för läsupplevelsen och om eleverna läser annorlunda om det finns uppgifter som skall besvaras.Metoden som användes var den kvalitativa intervjumetoden och det var 11 elever som intervjuades. Resultatet visade att det fanns ett intresse för texter och fiktivt berättande men att uppgifter inte alltid sågs som något positivt och att det kan vara lättare att komma i dialog med texten om läsning äger rum mer förutsättningslöst; Att kunna identifiera sig med texten är viktigt på så sätt att läsaren vill känna sig medskapande men det behöver inte vara så att det lästa ska vara nära kopplat till egna upplevelser. Engagemanget för texten kan grundas på handlingen, språkets uppbyggnad och vilka frågeområden som texten tar upp.

It is estimated that 22 000 contaminated areas exist in Sweden today. In order to classify the risk of contaminant migration from these areas and to prioritize which of these contaminated areas should first be treated, the Swedish Environmental Protection Agency (EPA) has designed a method, for the investigation of contaminated areas (MIFO). One of these contaminated areas is the landfill Gräsötippen outside Köping. The landfill has been used by both Yara AB and the Köping municipality between the years 1945 and 1975, and both industrial and household waste have been deposited there. The aim of this report is to survey which contaminants that can be found in the soil and water in the landfill Gräsötippen and to evaluate the migration of these contaminants.

Water is the most essential resource for life. In cases where drinking water is processed from surface water it is important to ensure the raw water is of good quality, and is suitable for processing through the water treatment plant.The drinking water for Västerås is sourced from Västeråsfjärden, in the western side of Lake Mälaren. The city itself is home to marinas, ports, a wastewater treatment plant, the Svartån outlet, sewage pumping stations and stormwater outlets. Because of the negative effects these activities have on surface water quality, Mälarenergi AB is interested in relocating the raw water intake point to Granfjärden, 10 km east of Västeråsfjärden. At Granfjärden the intake point would be less exposed to the activities in Västerås, and could be placed at a greater depth, resulting in better water quality.In this Master?s thesis the water quality and the pollution risks at Västeråsfjärden and Granfjärden sites are compared.

The main purpose of this thesis has been to find a way to evaluate the soil parameters for the Total sounding method (TS), such as the inner friction angles and settlement modules. This study only includes an analysis of soil profiles from the Stockholm region. The chosen location for the study is a proposed residential area east of Igelstaviken in Södertälje. Presently, the subject plot is located in a residential area and is also adjacent to a school area.Total sounding is originally a Norwegian soil testing method. The differences between the sounding methods (weight-, ram-, CPT-sounding) are for instance how the sound is driven into the ground and what kind of parameters that are registered.

Denna uppsats handlar om anställningsbarheten hos personalvetare, med fokus på informella kompetenser, i Sverige och Sydafrika. Studiens syfte var att utifrån ett arbetsgivarperspektiv undersöka vilka typer av kompetenser som gör personalvetare, vilkas yrke är att arbeta med personal- och arbetslivsfrågor på företags personalavdelningar, anställningsbara samt hur dessa typer av kompetenser värderas. Vidare var syftet att utreda om det råder en skillnad mellan svenska och sydafrikanska arbetsgivare vad gäller synen på ovanstående. Ur detta formulerades sedan fyra frågeställningar för att konkretisera syftet. Dessa syftade till att klargöra vilka typer av kompetenser som gör personalvetare anställningsbara i respektive land, hur kompetenserna värderades samt eventuella skillnader mellan länderna.
