Energiewendes påverkan på det nordiska kraftsystemet

Both the German and the Nordic power markets are seeing dramatically changed conditions due to an ongoing process of expanding the share of renewable production in the systems. For the German part this comes from heavy subsidies which have led to an explosive development in installed capacity of photovoltaic and wind based production. After the Fukushima incident it has been decided to shut down all Germanys nuclear plants. This capacity drop is however not of the same magnitude as the increase in renewables, but will impact the stability of the power system. The Nordic power system which already has a surplus of power sees an even further increase, coming mainly from construction of new nuclear plants in Finland and a general increase in wind farms.

Sensory profiling of Swedish white wines and a contextual analysis of Swedish viticulture

The aim of the study is twofold, to generate a sensory profile of Swedish wine today and to investigate the opinion of both wine producers and wine experts on viticulture in Sweden and wine from grapes grown in Sweden, achieved through a contextual analysis comprising a literature study and interviews with wine producers in Sweden and Denmark and wine experts from Sweden and Germany, and a sensory analysis at the company Ipsos. ?Mixed methods? was the chosen research strategy as the semi-structured interviews gave qualitative results and the sensory analysis would give quantitative results displayed as spider charts. There is a lack of studies investigating how the Swedish wine is perceived by consumers and consumers might be unaware that the Swedish wine, established through ?trial and error?, is increasing in quality every season, creating a need to display the sensory profile of Swedish wine to strengthening the perception of Swedish white wine. This study shows that the Swedish white wine today is a wine with a fresh, citrusy and flowery aroma and a fresh, citrusy and green apple taste, however, a sensory analysis cannot show if the attributes are those that are desired by the customer, a consumer test is necessary to conclude that. Trends point towards locally produced products, one reason why Swedish wine has great potential, yet the future needs to be secured through job opportunities and education. Creating an approval system for Swedish wine is suggested as a future improvement, it is a common procedure in most wine regions.

OTEC för Tarawa

Ocean Thermal Energy Conversion, OTEC, a technology using the temperature difference between cold deep seawater and warm surface water, can extract the work in the form of electricity. OTEC gives also synergies of drinkable fresh water. The temperature difference has an impact on the efficiency of the technology, which means that the feasibility of OTEC is geographically limited. The project intends to explore the possibility of replacing the atoll Tarawa?s present electricity generation with an OTEC plant and to explore synergies. In the present situation all of Tarawa?s electricity is generated by fossil fuels.

Uppfångning och kvarhållning av 134Cs och 85Sr i olika växtutvecklingsstadier

Emissions of radionuclides to the atmosphere can lead to wet deposition on plants in the event of rainfall. An increased level of radioactivity in the plants may occur due to interception and retention of the radionuclides. If the content of the plants is above the threshold limit value, entire yields may have to be destroyed. In order to prevent contamination or decrease the content countermeasures can be taken. The impact of the biomass, leaf area index (LAI) and growth stage of the plant on the interception and retention is important to know in order to decide which countermeasures to use. Weather may also be an important factor. In this work the interception and retention of 134Cs and 85Sr by spring wheat, ley and spring oil-seed rape was studied.

Neutralitet under kallt krig : En jämförande studie om alliansfriheten, västsamarbete och flygoperativa förberedelser, med tonvikt på åren 1949-1969

Sverige befann sig i en tid där andra världskriget fortfarande var i färskt minne. Geografiskt ligger landet centralt placerad mellan två supermakter, och det råder en spänd stämning i det internationella säkerhetspolitiska läget. Det svenska luftrummet har en stor strategisk betydelse i en internationell kontext. Med förtroendeskapande löften om alliansfrihet och ett avskräckande initiativ i form en av världens starkaste flygvapen försöker Sverige hålla sig utanför eventuella väpnade konflikter. Alliansfrihet syftande till neutralitet i krig är den officiella säkerhetspolitiska ställning Sverige har haft i nästan 200 år, och inte minst under två världskrig.

Föreställd o-gemenskap : Hur svensk press porträtterade frihetskampen i Tunisien och Ungern 1955 och 1956

This essay is called Imaginary non-community, How Swedish press portrayed the fight for freedom in Tunisia and Hungary 1955 and 1956 and it describes how two similar struggles for freedom are portrayed through the eyes of the most popular Swedish news papers Dagens Nyheter, Aftonbladet and Expressen. In 1955-56 Sweden is a country where the focus lies within the nation itself with economic growth and the building of folkhemmet. The Swedish social program for a more improved living condition. Outside of Sweden the cold war is reigning and the Swedish international politics is careful and passive. The fear of communism makes Sweden side with the western powers and therefore they (Swedish politicians and news papers) do not object to the French military effort to strike down the rebellions by force in North Africa.

Menstruationscykelns och p-pillers påverkan på den fysiska prestationsförmågan

Effects of Menstrual Cycle and Oral Contraceptives on Sport Performance During the menstrual cycle, there is a variation of the female steriod hormones estrogen and progestogen. These hormones has mainly reproduktive functions, but do also affect other physiological systems, which may have an influence on athletic performance. The use of oral contraceptives among female athletes matches the use among the general population. There is a concern among female athletes and there coaches weather oral contraceptives can affect the performance. The purpose of this litterature review is to determine the effect of the menstrual cycle and the use of oral contraceptives on athletic performance.

Stopover duration and field site selection by whooper swan (Cygnus cygnus) at Lake Tysslingen, Sweden

The aim of this study was to increase the knowledge about whooper swan (Cygnus cygnus) ecology to enhance the ability to predict and also to prevent the crop damage they cause. The largest proportion of damage in Sweden has been reported at stopover sites during spring migration in February, March and April. Therefore, this study focused on an important stopover site, Lake Tysslingen, situated in south-central Sweden. Specifically, the relation between the duration and period migrating swans stage at the stopover site and mean temperature (measured at three different weather stations) for the years 2001-2010 was studied. Furthermore, the swans´ selection for certain fields in relation to field type, distance to roosting site, a supplemental feeding site and forest edge within agricultural land surrounding the lake was analyzed.

Livslängden hos kyllagrade spermier vid artificiell insemination hos häst - kan den förlängas?

Över 90 % av betäckningarna inom Avelsföreningen för svenska varmblodiga hästen (ASVH) skedde med artificiell insemination (AI) år 2011. AI har många fördelar i avelsarbetet då hingsten inte behöver vara på plats när stoet brunstar, möjligheten att välja bland både nationella och internationella hingstar ger en stor valmöjlighet för stoägaren. I Sverige samlas sperma från hingstarna normalt sett tre gånger i veckan genom upphopp på en fantomhäst där ejakulatet samlas i en artificiell vagina. Trots mycket forskning är det fortfarande ca 20 % av hingstarna som lämnar spermier som inte lämpar sig för frysning. Innan nedkylning centrifugeras seminalplasman bort eller späds ut för att reducera inverkan på spermierna. Seminalplasman har positiv inverkan på spermierna vid naturlig betäckning men kan ha negativ inverkan på spermierna under lagring.

Koldioxidutsläpp vid sticklingsproduktion av pelargonium x hortorum i Kenya jämfört med Sverige :

Long transport of products is an environmental issue discussed to an increasing extent. The consumers are increasingly aware of how far our comestibles really have been transported. The increasing levels of environmental emissions are something that concerns people. The question is nevertheless delicate and many choose to ignore it. This is no longer an option.

Textil halksula

De senaste årens långa och kalla vintrar har lett till ett ökat antal halkolyckor. Genom att undersöka halkolyckors utsträckning samt halkskydd som fanns tillgängliga konstaterades det att ett behov av nya halkskydd fanns. Enkäter för att ge svar på användning av halkskydd togs fram och svar från personer i åldrarna 20-65 visade att man överlag inte använde halkskydd. I stor utsträckning berodde det på halkskyddens dåliga kvalité och den negativa stämpeln som fanns på dem . Textila material undersöktes för att finna lämpliga egenskaper.

Export av får och nötkreatur från Australien

Live exports of animals began during the late 19th century and are nowadays a valuable alternative to the slaughter industry in Australia. About four million sheep and half a million to one million cattle are exported annually from Australia to the Middle East and Southeast Asia. Most of these animals are exported for slaughter, but some cattle are exported with the purpose of breeding. One factor that has been the driving force for the live export industry is that countries through tariffs and other barriers have favored the import of live animals rather than the import of meat.The export means that animals with a great cognitive ability are exposed to a long chain of production from the farm to the market and there are many factors that can affect the welfare of the animals in a negative way. Some of the most serious are high temperatures and a high stocking density, although seasickness, noises and handling can also have a negative impact on the welfare of animals.
