Afrikas klimat : med fokus på Västafrika
Då de flesta människor i Västafrika, framför allt de som bor innanför kustzonen, livnär sig på jordbruk så är pålitliga väderprognoser och säsongsförutsägelser ett viktigt hjälpmedel i det dagliga arbetet och planeringen. I den här rapporten har en litteraturstudie gjorts för att öka kunskapen om de komplexa, både lokala och storskaliga, väderfenomen som ger upphov till nederbörd i området. Klimatet i Västafrika, ett område som mestadels täcks av regnskog eller savann, präglas av den västafrikanska monsunen som ger regnperiod under norra halvklotets sommar och torrperiod på vintern. Denna monsun visar på stor årlig variation när det gäller dess inledande faser, och prognoser som kan förutsäga dess början är nödvändigt när en jordbrukare ska planera säsongens verksamhet. Av många bidragande faktorer framgår det tydligt att ytvattentemperaturen i Guineabukten är en av de viktigaste parametrarna för monsunens startskede. Den intertropiska konvergenszonen, ITCZ, betraktas som monsunens nordligaste del och denna konvergenszon gör en plötsligt och relativt snabb förflyttning norrut, i fortsättningen benämnd som språnget, över ca 5 breddgrader, vilket av många ses som starten på regnperioden.

Självförsörjande elgenerering : Kan Orust bli självförsörjande på förnybar el?
Orust Kretsloppsakademi is a nonprofit organisation, with a goal of annually generate the same amount of electrical energy that is consumed. Orust is an island on the west coast of Sweden, north of Gothenburg. The population of 15 000 reaches 40 000 during summer, due to the large amount of vacationer. The total electricity demand is 174 GWh a year with a maximum power need of 32 MW. This report presents an analysis for the plausibility of their plan and from a power system stability perspective, the effects on the electrical grid.The conclusion is that the restraints for development of power generation from wind, solar and wave generation, are the power systems capability to transfer power, primarily in the transformers of the grid.
Det Intelligenta Huset : - En studie i hemautomation
Today all buildings contain some form of home automation. It might be heating controlled by athermostat or motion detectors controlling outdoor lighting.This paper,The Intelligent House, deals with the planning of a house in Kiruna, in the north ofSweden and further immerses itself in home automation or intelligent control in single-familyhomes. The house has been entirely planned, from layout to structural design and plumbing.The purpose of the paper has been to investigate the possibilities in home automation in singlefamilyhomes and to choose a suitable home automation system for the house being planned.The system has been designed and the costs and energy savings have been calculated.The system chosen for the house is called KNX and is the largest system for home automation inSweden. It is used to control heating, ventilation, lighting and alarm systems in the house. Is hasbeen found that KNX is very expensive and that the amount of energy, possible to save in thehouse, using the system, is relatively small.
Kampen om ett föränderligt Arktis : En jämförande studie av Rysslands och Kanadas agerande i Arktis och Arktiska rådet.
The Arctic region is rich in natural resources such as oil, gas, minerals and fish. Climate change causes the Arctic ice melt, making resource extraction possible as well as opening up new transport routes through the Northwest Passage and the Northeast Passage. This has led to competition and cross-border strife among the Arctic States. The two largest states in the Arctic are Russia and Canada, which are also members of the Arctic Council. Russia and Canada are at the moment involved in several disputes regarding the Arctic territory where the ownership of the North Pole is one example.
Keep it real and Quick : En undersökning om hur företag bör kommunicera mot 80-talister
Today we live in a more or less globalized society where borders do not pose the same obstacle as before. This is why it is interesting to examine whether different countries have similar views on how to communicate with a specific audiencePurpose: The purpose of this thesis is to use the data gathered to inform businesses with information. The information can then be used to assist companies when it comes to advertising, the design of messages and the choice of media channels when communicating with people born during the 80?s. Furthermore, the investigation intends to find out if there really is a global market for people born during the 80?s.Method: The authors believe that a purely quantitative or qualitative approach is not appropriate.
Hedging Core and Non-Core Risks: Evidence from Forestry and Paper Industry
A great number of empirical researches show that hedging is associated with higher firm value, particularly hedging interest rate and exchange rate. However, there is no clear support for value-added risk management hypothesis in the case of producers of commodities. Moreover, according to Shrand and Unal (1997), there are two types of risks, core business risks (or core risk) and homogeneous risks (or non core risks), which are based on a firm's comparative advantages with respects to the source of risk. Firm can earn economic profits for bearing core risks in which it has a comparative information advantage. Firm earn a zero economic rents for bearing non-core risks, where it has no advantage information than its competitors.
Visuell planering enligt Lean : Optimering av samordning i syfte att höjakvaliteten i grundläggningsprojekt
Construction production always contains different disciplines whose priorities andinterests can be very diverse. Good communication and coordination are essential tominimize misunderstandings and achieve good quality in the end result. This makesplanning a central part of the production management. In a world where conditionscan change as often as daily, being well prepared increases the opportunities to stayflexible and decrease negative effects of the changes.This study has been done in association with Skanska Foundations district North inStockholm in order to investigate how visual planning can be used in the productionmanagement to optimize the coordination and the quality.The history of Lean started at Toyota, but the concept are now spread over theworld and are used wide outside of the car industry nowadays. What?s challengingabout Lean in foundation projects is to embrace a long-term perspective and invest insolutions that are profitable in the longer term, instead of solve problems by onlytreating the symptoms.A holistic perspective is crucial in order to truly understand Lean.

Spårtrafik i norra Stockholmsregionen
Northeast Stockholm is a region developing fast. There is already a great need for new transport solutions for the people commuting to the city, since long queues slow down car traffic and the local railway, Roslagsbanan, needs to be upgraded to attract more travelers. The competitive advantage of rail?traffic over the car when it comes to greenhouse gases and air pollutants is another reason to develop Roslagsbanan.This report investigates the differences between car and train to create a basis for a proposed expansion of Roslagsbanan. Once the proposal is presented, costs, emissions reductions and public benefits are analyzed.
Salutogenes Africa - En kvalitativ studie om det salutogena perspektivets inflytande på behandlingsarbete i Sydafrika
Denna uppsats har haft som syfte att undersöka olika uttryck för ett salutogent perspektiv vid behandlingen av missbrukare på behandlingshem i Sydafrika. Frågeställningarna var: ? Vad är personalens uppfattning om huruvida man arbetar utifrån ett salutogent perspektiv?? Vilka möjligheter ser personalen att arbeta ur ett salutogent perspektiv?? Vilka resurser ser personalen hos patienterna och i deras omgivning?Det empiriska materialet för att uppfylla syftet och svara på frågeställningarna säkerställdes genom fem kvalitativa intervjuer och observationer vid ett behandlingshem utanför Kapstaden i Sydafrika.Den teoretiska utgångspunkten för uppsatsen kommer från Aaron Antonovsky och hans salutogena KASAM-teori. Den bygger på tanken att man ska fokusera på det ?friska? i individen, på personens resurser.
Afrika, en växande marknad : svenska företag etablerar sig i de afrikanska länderna
Tidigare studier visar att Afrika är en växande marknad med möjligheter för svenska företag, men det är en marknad som innebär risker. De svenska företagen har idag en stark närvaro med ett gott rykte och bidrar med kunskap och kvalitet. Trots stora naturtillgångar och ekonomisk tillväxt råder en ojämn inkomstfördelning med fortsatt utbredd fattigdom och underutvecklad infrastruktur. De afrikanska ländernas egna företagare är en viktig del i deras ekonomiska tillväxt. För att skapa vidare utveckling bör de afrikanska ledarna ta större ansvar för den unga arbetskraften.Studiens syfte var att studera hur, var och varför svenska företag har etablerat sig på den afrikanska marknaden och se om och hur etableringen skiljer sig åt för de utvalda företagen.
Vivesholm : djurbenen belyser den gotländska medeltida borgens husdjurshållning samt husgrundernas användningsområden
The castle Vivesholm is located about two miles north of Klintehamn on the west side of Gotland. The castle was built around year 1395 and burned down in the end of the 14thcentury. Around the 17th and the 18th century the castle was re-used. However, the emphasis on its use is during the middle ages.This paper aims at getting an insight in the animal husbandry at Vivesholm by analyzing the osteological material. The analysis revealed that bones from sheep/goat were more common than bones from cattle.
