The aim of the study was to compare productivity in first thinning of birch stands, when either energy- or pulpwood was harvested. The systems total profitability was also compared by including forwarding and chipping costs. A Gremo 950 HPVR harvester was used and the same driver was used under the entire study. During the pulpwood harvest a Logmax 4000b harvester head was used and a feller buncher head made by Silvatec was used during the energy wood harvest. Six study unit pairs were located in a birch dominated stand outside Ängelholm in Skåne.

Since energy simulations are used to verify that projected residential buildings will reach the current energy requirements it is important that the results are reliable.This report investigates the extent of uncertainty in energy simulations, estimates the causes of the uncertainty and its economic and environmental consequences.The method used in this report is based on three validation methods; empirical validation, analytical validation and comparative validation. The analysis was carried out for five multi-family dwellings in Uppsala with installed meters for energy measurements. One of these objects, Klockarlunden, was studied in more detail than the others.The results show that the deviations are between 10 and 29% for the studied objects, which means that the uncertainty is estimated to be at least 29%. All simulations underestimate the buildings need of energy. The simulation for Klockarlunden can predict the energy consumption to be within the range of 46-98 kWh/m2year with 90% confidence level based on the current uncertainty.

During whole-tree harvesting, there is a risk that the soil will become impoverished of nutrients. To prevent this, nutrients are returned to the harvested site as wood ash. This action also reduces the risk of soil acidification. Nevertheless, the ash does not result in any increase of tree growth if it is added on mineral soils, which is where the measure is most commonly used in Sweden. Due to the lack of growth response, the interest from landowners is small, which is why ash amendment today is not done enough to compensate for the need.

The production of oilseed rape is an important issue in Sweden and those who never have grown oilseed rape (OSR) are now willing to try. It is always a risk to grow oilseed rape, specially winter OSR, because of outwintering. This risk increases as you go north and therefore establishment and autumn growth is very important. These are some of the reasons that I have chosen to write about the establishment of winter oilseed rape in Middle Sweden. There are many factors that influence the outcome of the establishment, e. g.

The purpose of this thesis is to investigate the possibilities for shore side electricity in the ports of Västerås and Köping. A technical solution to connect the vessels to the local grid is suggested and the investigation is also aiming at an understanding of how the environment is affected by the use of shore side electricity. Furthermore, the costs of shore side electricity are considered.The maximum power demand of a vessel visiting the ports today is relatively small, but the ships visiting the ports in the future might have a larger power demand. The suggested dimension for the system is 5 MW and the result shows that the shore side electricity requires the power distribution to the ports to be expanded. The most useful solution in the ports is to connect the ships with 12 kV from a connection box in a pit at the quay.The investigation of the costs shows that it is cheaper for the ships to use electricity compared to the marine fuel.

Barn- och fritidsprogrammet a?r ett yrkesinriktat gymnasieprogram med mycket la?g etableringsgrad pa? arbetsmarknaden. Syftet med va?rt arbete a?r att analysera elevers val till programmet och vilka tankar de ba?r pa? na?r det ga?ller mo?jligheterna att fa? arbete. Va?ra forskningsfra?gor handlar da?rfo?r om hur eleverna resonerar info?r valet av gymnasieprogram, vilken kunskap de har om arbetsmarknaden vid valtillfa?llet, vilken betydelse de tillma?ter mo?jligheten att fa? arbete efter utbildningen samt vilka fo?rva?ntningar de har pa? tiden efter avslutat gymnasium.

I dagens skolor har jakten pa? fusket o?kat. Antiplagieringstja?nster a?r ett vanligt fo?rekommande medel fo?r att ta reda pa? om fusk fo?religger eller inte. Pa? detta vis kan man la?tt la?gga juridiska och moraliska aspekter pa? fuskande, men kan problemet ligga i sja?lva pedagogiken? Att finna gra?nslandet mellan plagiat och imitation a?r la?ttare sagt a?n gjort.

På senare år med den fortsatta globaliseringen har miljöfrågor blivit allt viktigare. Eftersom transportsektorn står för en stor del av den totala miljöpåverkan är det viktigt att logistikföretagen tar ett miljömässigt ansvar och arbetar med så kallad grön logistik. På grund avde ökade avstånden vid global handel och ökade bränslepriser är det viktigt med miljövänliga alternativ. Syftet med denna studie är att undersöka hur de globala logistikföretagen bedriver sitt miljöarbete, främst kring transporterna. Detta sker genom en studie av vetenskapliga artiklar och intervjuer med miljöansvariga hos Schenker, DHL och Green Cargo.

It?s a fact that the climate is affected by the vehicle that runs on the worlds roads. But theconstruction of the road itself is rarely thought of as a climate threat. Svevia and the Swedish roadadministration have opposite views of how the construction of roads should be carried thru. It?sthe difference between those two construction methods that is the base in our thesis.The amount of energy use or the emissions are not analyzed for neither the Swedish roadadministrations nor Svevias construction models.

The project has been done in cooperation with Schenker Åkeri AB in Sweden, Halmstad. Theproject is based on an inspection made by Arbetsmiljöverket, where they found minorshortcomings with distribution of goods for the employees. The project is an investigation ofthe drivers? working environment.Schenker Logistics is one of the world's leading providers of integrated logistics services.Schenker Åkeri AB is a subsidiary to Schenker Logistics and transports 2.4 million tons ofgoods yearly.The project started with a background study to evaluate drivers working environment. Wehave studied goods receptions, the working environment, strain injury and injury mechanisms.Methods used was observations, tests, questionnaire surveys and ergonomic andbiomechanical calculations.One result of the study is a working model, which gives recommendations for the maximumweight a driver should push and pull.

In published studies it is found that the fuel consumption on a forwarder is relatively constant, on time basis. A certain variation between different sizes of forwarders occurs as well as between different working elements. The aim of the study was to establish a forwarders comparatively fuel consumption when driving on road and in the terrain, loaded and unloaded, with high and low gear and with high and low speed as well as with hydrostatic and hydrodynamic transmission. A hypothesis was that low rpm gives lower fuel consumption on distance basic, at all trials. The test driving was made with a Hemek 750 which is a three geared hydrostatic machine and with a Hemek 700 which is a hydrodynamic machine with six gears.

Syftet med studien ?r att identifiera arbetsmetoder avsedda att integrera resultatet fr?n bed?mningen av den finansiella materialiteten med den f?retagsspecifika riskhanteringen. Metod: Kvalitativ litteraturstudie och intervjustudie Resultat: F?r att skapa en effektiv och integrerad riskhantering i f?retaget ?r det avg?rande att till?mpa ett holistiskt syns?tt d?r riskhantering inte isoleras till specifika avdelningar, och d?r h?llbarhetsteam och riskteam jobbar integrerat. Enterprise Risk Management (ERM) kan fungera som en strategi f?r att l?nka samman olika processer och hantera sammankopplade risker, vilket ger en helhetsbild av f?retagets riskexponering d?rmed ?ven integrera risker enligt den dubbla v?sentlighetsanalysen.
