Due to soft grounds in combination with seasonal variation in soil humidity, there is a lack of stands that are possible to cut during spring and autumn in some geographical regions. For Holmen Skog this sometimes means that a large proportion of the contracted private forest is cut during the winter when the ground is frozen. One consequence of this is that the proportion of winter stands in the stand bank of own forest increases while spring and autumn stands becomes a scarcity. This in combination with milder winters, especially when there is a long period of reduced bearing capacity in spring or autumn, means that the situation rapidly can become critical. The overall goal with this study was to generate basic data for decision support in the work to achieve a sustainable distribution between own forest and contracted private forest in the stand bank. The study took place at Holmen Skog, district of Umeå, during autumn 2007 and was based on interviews and an analysis of harvest planning and delivery data. The study showed that there is a problem with how the cutting is distributed between own and contracted private forest during the year and that it foremost is the proportion of winter thinning of own forest that has increased in the stand bank.

Trade is important for every country in the world. Commodities are transported between rich and poor countries everyday. Some of the trading partners are EU and Ethiopia, this because of less expensive commodities from EU than they are in Ethiopia. The most important agricultural commodity is wheat. Ethiopia is a poor country, whose inhabitants mostly are living on agriculture.

Today?s climate research shows that the climate may increase its temperature. One sector that is being threatened by global warming is the winter tourism of the Swedish municipality A?re. Tourism is an important economical source of income in A?re and is now threatened by a shortened winter season.

Crop efficiency in utilizing available nutrients is an important factor in increasing produc-tivity and reducing the environmental impact of agriculture. Nitrogen is the nutrient that plants need in the largest quantity and wheat, along with maize and rice, is the world's most cultivated crop. In this work, the Nitrogen Use Efficiency, NUE, during the major growth period, HTP, of twelve different spring wheat varieties, were examined. The NUE was calculated as the product of uptake efficiency of nitrogen, UN, and the conversion effi-ciency of nitrogen to biomass, EN. The purpose of this work was to find if there are varietal differences in NUE and its components among the twelve varieties and to link a high NUE to specific characteristics of the varieties.

The wild boar population grows rapidly in number in Sweden, and it has been predicted that the annual number of shot wild boar will soon exceed the cull of moose. According to estimates, the Swedish population encompassed some 150 000 individuals in 2010. The mean annual harvest has increased by 30% since 1990, indicating that the wild boar is a species we must learn to manage sustainably. A successful management of the boars aims for a population in balance with agriculture and traffic, and also provides good hunting opportunities. For this to be possible, understandings of several aspects of the ecology of wild boar is needed. The sows in this study had an average homerange of 707 hectares during summer, and 659 hectares in winter.

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.

Syftet med denna undersökning är bidra med förklaringar till varför upplevdaljudkvalitetsskillnader kan uppstå mellan olika akters framträdanden vid event och festivalertrots att de använder samma utrustning och är i samma lokal och att förklaringarna ska utgöraen kunskapskälla för dem som eftersträvar en god ljudkvalité vid liveframträdanden.De metoder som har används är fallstudie, webbenkät, intervjuer och egen observation.Webbenkäten användes på Dreamhack Winter 2014 där en grupp undersökningsdeltagaresvarade på frågor om två olika DJ-akter på scenen i D-hallen, Elmia. Fem personer deltogsom intervjupersoner: scenansvarig från Dreamhack, tre ljudtekniker ifrån olika ställen iSverige och en person som jobbar med ljudteknisk konsultation och ljudmätning. Samtligaintervjuer genomfördes via mail. Intervjuerna eftersträvade att ge kunskap om dessa personersfunderingar kring ljudkvalitetsproblemet och scenansvarig svarade på frågor om scenen påDreamhack. En observation av upplevd ljudkvalitet och ljudteknikernas arbetssättgenomfördes av mig själv på Dreamhack Winter 2014.Resultatet från såväl enkätundersökningen som den egna observationen visar att inga storaupplevda skillnader fanns mellan de två akterna på Dreamhack Winter 2014.

This study is one of five that has been done based on Lunds Energi?s planned investment in bioenergy. The plan is to build two large burners, at Örtofta, that?s going to be supplied with biofuels. In this study I take a closer look on the profitability when you choose to sell your cereal as bioenergy. I?ve been calculating with selling the straw from the grain crops and winter rape, selling the rye weat as whole crop and fertilize the hemp with sewage sludge.

Mould is a common contamination in cereals. The growth of mould can stimulate mycotoxins production andsome of which at critical concentrations cause health problems in humans and animals. Fusarium is one of thefungus species that has been found in crops and can cause major problems for farmers such as reduced harvestand economic losses. A group of Fusarium species, Fusarium avenaceum, Fusarium poae and Fusariumtricinctum express a mycotoxin, enniatin. The limited information available today about enniatin-forming fungiis that they grow out on fields of wheat in colder climates.

I den här uppsatsen undersökts hur greppet mise en abyme kan användas som ett dekonstruktivt verktyg i fiktionen. De tre romanerna som ligger till grund för uppsatsen är Montecore - en unik tiger av Jonas Hassen Khemiri, Sara Stridsbergs Drömfakulteten: tillägg till sexualteorin samt If on a Winter?s Night a Traveler av Italo Calvino.Gemensamt för romanerna är att de alla genom att kommentera sin egen tillkomst och låta boken uppträda i boken skapar en osäkerhet i frågan om vad som är sanning och inte i de respektive berättelserna. Sanningen rubbas och dekonstrueras om vartannat genom användandet av mise en abyme..

Abstract In order to make the modern agriculture less dependent on non-renewable external inputs, it has to rely more on ecosystem services. The agricultural system produce not only food, fiber and fuel, it also generates other ecosystem services such as e.g. photosynthesis, recycling of nutrients, influencing local microclimate, pollination, biological control and detoxification of noxious chemicals. This study is an attempt to get a better understanding about the interaction among different ecosystem services and different habitats capacity to generate them. An evaluation of eight different methods is done. The ecosystem services studied are the ability to absorb solar energy, biomass production, botanical diversity, decomposition and natural predation of aphids.

Today cultivation of cereal in Sweden has high costs for establishment in relation to the rest of the world, and if this cultivation will be able to continue, the farmers have to control their costs. It is important to see all costs, not the maximum harvest achieved, but the net result. All farmers have different conditions with respect to soil, direction of the farm and were the farm is located geographically. With the right knowledge and ambitions, we think most farmers could change to reduced tillage. In this paper we have tried to find out if reduced tillage is an alternative for farmers.

Stem rust, Puccinia graminis, has caused enormous yield losses throughout history which have had significant consequences for oat and wheat production. Today in Sweden stem rust is only reported from rye, oats and wild grasses. Stem rust infections in wheat have become unusual due to the general use of resistant wheat varieties and also due to the eradication of barberry, Berberis vulgaris, the alternate host for P. graminis. According to international sources, new races of P.
