Två nya trailerkoncept för transport av rundvirke hos Stora Enso : en analys av prestation och flexibilitet

The need for roundwood transport capacity vary throughout the year. The need during a period is influenced mainly by the volume transported the period, the number of days during which transport can be carried out, seasonal variations in road conditions and the weight of the roundwood, and the origin of the wood (private forest owners/ forest companies). The need for transport capacity generally increase during the winter and in spring, after thawing. Lack of logging trucks combined with a lack of drivers for these trucks make it hard to hire extra help during periods of increased transport capacity needs. It is also very expensive to keep logging trucks for use only during these periods. In this thesis, two new concepts based on the partial transport by truck tractors have been examined, to find out the possibility for increased performance and flexibility.

Modell för fördelning av kostnader i lager

Distrilux International AB, a company within the Electrolux-group, works among other things with storing of products from other companies in the Electrolux-group. This rapport contains a cost analysis of the two Distrilux warehouses in Motala and Mariestad. The company offers five services in these warehouses, in-loading of products from a local factory and from external factories, storing, out-loading of products to Sweden (domestic) and for export. Since there has been some hesitation of the accuracy of the price-model of today, a master's thesis has been advertised. The purpose of the thesis has been to investigate the agreement of the price-model of today and the apportionment of the costing in warehouses.The main problem is to determine which activities is to be considered important in the price-model.

ALK?RR - K?LLA ELLER S?NKA F?R V?XTHUSGASERNA METAN OCH LUSTGAS? Empirisk studie av v?xthusgasutbyte i kustn?ra alk?rr p? den svenska V?stkusten.

Due to global climate change and the rising levels of greenhouse gases (GHG) in the atmosphere, the interest for seeking solutions for mitigation has increased. While much attention has been directed towards technical solutions such as carbon capture and storage (CCS), biogenic carbon sinks has also garnered significant attention. Previous studies have shown that coastal ecosystems such as seagrass meadows and mangroves have a much greater capacity for storing carbon (C) compared to terrestrial ecosystems. That raises the question if other coastal ecosystems, such as coastal wetland forests, that previously haven?t been considered as blue carbon habitats also contribute to coastal carbon sink capacity.

Stage-discharge equations for lakes without disharge measurementsSimon AnderssonIn 2015 all lakes, rivers, coastal water and groundwater should be of good ecological statusaccording to the water framework directive from the European Union. In the process ofimproving the quality of Swedish water bodies, knowledge of where problems occur isneeded in order to utilize the resources optimally. The ability of lakes to store water is animportant factor since it controls the flow of water through the country. A stage-dischargeequation is a mathematical relation between discharge from a lake and its water level. Bybetter understanding of stage-discharge equations for lakes, their storage capacity can bedescribed better in hydrological models.This master thesis aims to evaluate methods for determining stage-discharge equations forlakes where a variable amount of field measurements is available.

V?RMEAKTIVERADE TISSUES P? TRANSPARENT PAPPER En j?mf?rande studie vid revlagning

Works on transparent paper, also commonly known as tracing paper, have been described as ephemeral or temporary working documents and they usually number large quantities in archival and museum collections. They have therefore previously been considered of lower priority and can be found in poor condition due to a lack of treatment or suitable storage prospects. In addition, transparent paper can be very sensitive to moisture and reacts by deformation or loss of transparency. Due to the volume of these works and the necessity of treatment, there is a call for simple and efficient conservation methods. A common solution in archives for the treatment of water-sensitive works on paper has been the use of heat-activated tissues as they can be applied without the introduction of solvents. There is little published about the use of heat-activated tissues on transparent paper and is mentioned only briefly in existing literature.

Smak och konsistens hos ost : en litteraturstudie kring årstiderna och fodrets inverkan

To enjoy the richness of the grazing cows and high yield during the summers, even during the winter, cheese has been the way to store milk for thousands of years. Nowadays yield is high all year around and the cheese production is possible during all seasons. The aim of this paper is to investi-gate how and why the seasons influence taste and texture of pressed and ripened cheese. Milk is composed of proteins, fat, lactose and water but contains also a lot of vitamins. The quality of milk is very important for the final constitution of cheese.

Det självförsörjande passivhuset

The housing sector uses 40 % of the energy in Sweden and half of the electricity usage. Theuse of energy is the main reason to the increasing rate of carbon dioxide in the atmosphere.This is the main motive but also a wish of higher safety, that is a higher rate of selfsufficientenergy production in Sweden, we want to decrease the need of using fossil fuel. Now whenthe energy price rise, the interest in energy issues increase and more people discuss thepossibility of reducing the usage of fossil fuel. A change to renewable energy such as sun,wind and water is the only solution where we can get a sustainable development.One way to contribute to a better use of energy is to build in the principle of passive house.The house is being built with a thick and tight insulation. If you use a heat-exchanger withhigh degree of efficiency and a final heating battery on the ventilation system, the heat fromlamps, devices and the ones living in the house should be enough to fulfil the criteria ofliving.

Energilagring för företag i Finland

Förnybara energikällor som vindkraft och solenergi är numera väletablerade energikällor i stora delar av världen. Stor tillväxt av förnybara energikällor vars elproduktion inte kan förutses då den är beroende av vädret gör energilagring till en viktig komponent inom elsystem. Under starka vindar kan ett vindkraftverk överproducera el. Det innebär att kraftverket producerar mer el än vad som går att sälja på elmarknaden och man tvingas ge bort elen. Under andra perioder då det nästan inte blåser alls kan elpriserna stiga enormt eftersom det blir brist på el.

Energiberäkningar för passivhus

AbstractClimate and environmental issues are of paramount importance. Researchers agreethat we must all contribute to a reduction of gases that contribute to climatechange. Energy consumption must decrease within all sectors and the promotionof renewable sources of energy must be introduced.Each sector should aspire to decrease its energy consumption. Energyconsumption is strongly linked to waste gases that contribute to climate change.Passive houses are a part of the construction industry's methods to attain energyconservation.Passive houses are derived from low energy houses and super insulated houses. Apassive house is intended to obtain heat from the inhabitants and through theiractivities.

Evaluation of tools for analysis and quantification of Fusarium mycotoxins

Fusarium head blight is a large problem world wide which reduces the yields and the quality of small grains. Shrunken kernels with decreased thousand kernel weight as an effect and pro-duction of mycotoxins are some of the problems caused by infection of Fusarium spp. To avoid toxin contaminated bulks to enter the food and feed chain it is important to have tools for prediction and analysis of the fungi and toxins. Good prediction methods are also impor-tant in the breeding industry since early identification in trials of lines with high resistance or susceptibility simplify the work. To compare different techniques for these objectives this project was initiated.

Hur hanteras vildsvinets (Sus scrofa) populationstillväxt i Sverige idag?

The wild boar was reintroduced to Sweden in the 1970´s from enclosures that they had escaped from and by a government decision in 1988 they were considered a part of the natural fauna again. The purpose with this report is to examine the effects of the wild boars? reintroduction both on their welfare and on other aspects, such as how their population growth affects Sweden. This was done by gathering information from scientific literature and by performing three interviews. Another purpose is to briefly overlook live trapping and other common regulation methods.
