The low bearing capacity of roads during the spring thaw and periods in the autumn leads every year to increases costs for Holmen Skog. To reduce costs and increase accessibility Holmen Skog decided to install and test a CTI-system. Central tire inflation (CTI) is a system that makes it possible to monitor and vary a vehicle?s tire inflation pressures from the cabin, while the vehicle is in motion. When tire pressures are reduced, the area of the contact surface between the tire and the road increases, thus reducing the ground pressure. The purpose of this study was to evaluate the CTI-equipped vehicle and analyze if the CTI technology is economical defensible during the thaw 2005.

The climate changes that are occuring in the world have resulted in that the EU callingfor a 20 % reduction in energy consumption to the year 2020, to reach that goal theEU want the public sector to go forth as a good example. Västfastigheter owns andmanage the hospital buildings in the Västra Götaland region. To be able to reducetheir energy usage Västfastigheter has hired several consulting firms to chart out theenergy consumption on each hospital building. The biggest energy savings potentialhave been calculated and what the cost will be to perform each action. The energyaudit have been completed and stand as the decision basis for Västfastigheter?s choiceon which action packages that should be implemented.

The aim of this master thesis is to show how the dissemination of scientific information took place and developed during the 19th century. The main focus is Lund University. Therefore I have formulated two questions: How did the five heads of the history department at Lund University publish their research findings in the 19th century? What factors in society influenced the scientific spreading of results in the 19th century? To assess the scientific reliability of the sources I have used a method based on source criticism and hermeneutics. The thesis covers important concepts such as the exchange of publications between the universities, commercium litterarium and Akademischer Tauschverein and also the development of Lund University yearbook.

Return handling is often regarded as a slow and complex process. Studies have shown that it is not unusual for a return to cost up to nine times as much as a standard outbound delivery. An efficient return handling process is therefore essential to all competitive companies dealing with logistics. This report investigates, analyzes and gives suggestions on development with the purpose to improve the return handling process at LensLogistics AB in Kista, north of Stockholm, Sweden. The study has been conducted from a deliberately practical point of view in order to suggest improvement suggestions possible to implement and thereby change the entire return handling process.

During a fire large amounts of particles and unhealthy agents occur.  Polyaromatic hydrocarbons (PAH) and toxic metals are examples among many others. These agents have a capacity to bond to particles and when the fire is extinguished, the particles can be transferred with the extinguish water into the soil and to the groundwater.Recent studies in particles have been conducted. A study by Ulrika Iverfelt (2014) reviled that the particles from a fire contained large amounts of both PAH and metals, which is consistent with earlier analyses. Her column experiments with particles in the size ? 11 microns and ?100 microns in silica sand, reviled that the larger particles was immobilized because the transportation was influenced by sieving or physiochemical particle and surface interactions.The transport of the particles in soil and groundwater is regulated by two main mechanisms: physiochemical surface interactions and straining.

New technology and urban sprawl have resulted in almost half of the population in Sweden being insufficiently physically active. The sedentary lifestyle causes heart- and vascular diseases, diabetes, high blood pressure, cancer, stress etc. in the population. One of the biggest priorities in the society is to promote more physical activity. Through literature studies and a questionnaire this paper will examine how we can design the built environment in order to promote physical exercise and if we can change the sedentary lifestyle with a outdoor environment that invite physical exercise. There are both internal and external factors that have importance for people?s physical activity.

Wastewater contains biodegradable materials, which are often measured as BOD7.Trickling filters are sometimes used as a purification step for BOD-reduction. Atrickling filter is a tower, which is filled with a carrier material. Microorganisms growon the carrier material in the form of a biofilm. This biofilm consists mostly of bacteriathat purify water from BOD.In Älgarås? wastewater treatment plant the water is purified by a trickling filter.However the treatment plant has difficulties reaching the emission requirements forBOD.

Kusoffsky, Magnus (2010) Spårväg eller trådbuss ? Idéstudie om strukturerande kollektivtrafik i Örebroregionen [Light rail or high-capacity trolleybus: A proposal for high-quality public transport in the Örebro area] Kulturgeografiska institutionen, avancerad nivå Masteruppsats för masterexamen i Samhällsplanering, 30 ECTS credits Handledare: Lennart Tonell Språk: SvenskaDen här uppsatsen handlar om samhällsplanering och kollektivtrafik i regionen omkring Örebro, Kumla och Hallsberg. Uppsatsens syfte är att presentera en vision för en långsiktigt hållbar Örebroregion, med ett hållbart transportsystem där kollektivtrafiken har en hög marknadsandel.Visionen preciseras i två scenarier, som bygger på två olika trafiksystem, nämligen spårväg och duospårväg, respektive prioriterad busstrafik med trådbuss. Båda scenarierna bygger på det nuvarande busslinjenätet i Örebro, och båda innehåller en direkt anslutning från Örebro universitet till Kumla och Hallsberg.Metoder som används i uppsatsen är scenarioplanering, backcasting, semi-struktrurerade intervjuer och deltagande observation.Avhandlingen innehåller en litteraturstudie, som bygger på tre målbilder för samhällsplanering i Sverige: integrerad trafik- och samhällsplanering med kollektivtrafik som norm, kollektivtrafik med strukturerande egenskaper, och integrering av lokal och regional kollektivtrafik.I två scenarierna beskrivs bland annat grundläggande tekniska specifikationer, linjenät, täckningsgrad, restider, kostnadsberäkningar, konsekvenser för stadsmiljö och samhällsplanering. Systemens för- och nackdelar jämförs, och rekommendationer lämnas för åtgärder på kortare sikt i kommunerna Örebro, Kumla och Hallsberg.

This study is based on interviews with five unit managers working in the functional disabilities business. The purpose of this paper is to examine how these unit managers see their roles and their leadership, and to give the reader an insight into what it might entail to be a manager in social work. Theories applied are the role theory and three leadership theories. The previous research this study made ??use of affects ?leadership in social work" and "manager's role and leadership style."Being a unit manager of the functional disabilities business means having a so-called middle management position, which entails expectations being directed upon them from various avenues.

Local cultural environment planning in Sweden often comes to rely on municipal heritage plans. These plans are meant to facilitate management of local cultural values, work as a tool for local planning and increase awareness of cultural environments for the public. In the last decades public participation in planning has become more and more of the ideal strategy, challenging the idea of cultural environment planning as an expert-led field. The idea of the field as one that implicates public participation as a strategy has been fortified in Sweden through national goals, government bills and conventions. Nevertheless the implementation of public participation in municipal heritage plans remains quite uncharted. The aim of this study is to explore public participation in regards to how municipal heritage plans are developed and the perception of public participation in cultural environment planning amongst professionals, comparing bigger and smaller municipalities.

The voltage level in the power grid varies due to variations in load and production. Normally these variations are manageable, but they may be excessively large during a disturbance. If the voltage is too high it may damage the equipment in the grid and too low voltages may cause problems like voltage instability. The magnitude of the voltage variation depends on the short circuit power capacity of the point of interest.This problem may become lore prominent due to automatic voltage regulation that acts on shunt reactors and shunt capacitors. When the shunt reactor is connected or disconnected to the grid it may cause such large changes in the voltage that the shunt reactor starts hunting.

This study investigated potato growing in beds as an alternative to conventional ridges.It was based on results from field trials on bed-grown potatoes carried out by Halland Rural Economy and Agricultural Society in 2007, studies of literature and interviews with farmers with experience of bed growing of potatoes. Due to their shallow root system, potatoes are one of the most drought-sensitive crops. Potatoes are often grown on sandy soils with poor water-holding capacity. Factors such as total yield, tuber size distribution and quality defects are negatively affected when water becomes insufficient. Wide beds have a more flat top which leads to more uniform water infiltration. Further on, beds have lower soil surface area due to its shape, and therefore, retain water more efficient. In the field trials, which were carried out at the Stjärnarp Estate near Halmstad, potatoes were grown in beds alongside a conventional ridge-grown crop.

Purpose: Corporations today see a greater responsibility towards society regarding the environmental impact of their actions, using available transportation options that are more eco-friendly can reduce this impact significantly. Martinsen and Björklund (2012) identifies a set of gaps between supply and demand of green logistics services. This paper aims to address what it is that affects the demand for these alternative solutions and what could be done to increase the usage of them, thereby decreasing this gap.Design/methodology/approach: A quantitative study with six Logistics Service Providers (LSP) and 24 companies that purchase transportation services, all operating in Sweden. Data is collected through semi-structured telephone interviews with people responsible for the purchasing of transports as well as key account managers within the service providing companies.Findings: Just as the LSP?s interviewed in this paper thought, the main focus of the transport buying companies are the costs.

Peat  lands  are  a  great  potential  resource  for  increased  forest  growth  in  Sweden, there  are  approximately  6.5  million  hectares  of  peat  lands,  whereof  around  70% produce less wood than one m3sk/ha and year and are therefore classed as forest waste  land.  There  are  over  200  000  hectares  of  peat  land  that  is  already  drained and  wooded,  and  that may  be  suitable  for  fertilization.  Forest  production  on  peat soils  usually  requires  drainage  and  fertilization.  Dewatering  requires  ditching  the area, so that the roots can have access to oxygen. Nitrogen is often abundant in the peat but other nutrients; especially potassium is in short supply. The  purpose  of  this  work  was  to examine  the effects  of  potassium  fertilization  on the  growth  of  spruces  that  were  planted  on  drained  peat  land  and  how  different amount of fertilizers affects the growth. Potassium deficiency is strongly growth inhibiting, since potassium is important for substance  transport  in  the  tree.  Potassium  is  also  important  for  the  carbohydrate formation, and because increasing the sugar content of the cells constitutes a lower freezing temperature does potassium availability in the soil play a major role in the winter  resistance  of  many  species.  Potassium  is  not  found  in  any  organic compounds in the tree, but is present in cell and tissue fluids. A fertilization trial was started in 1978 in Siljansfors Experimental Forest. The plots in the experiment were fertilized with different amounts of potassium and one plot was  left  without  fertilization.  All  plots  that  were  fertilized  with  potassium  grew considerably better than the unfertilized plot. The difference in production between the unfertilized plot and the plot that received the most potassium was 7.2 m3sk/ha and year. The unfertilized plot can still be classified as waste land. The theoretical production capacity was estimated using a Swedish system for site quality  estimation  of  wetlands  after  ditching  (dikningsbonitering).  The  plot  with most  potassium  produced  after  fertilizationaproximately  in  level  with  theoretical estimations.  Key  words:  Peat  land,  Fertilization,  Ditching,  Growth,  site  quality..
