Fo?rutsa?ttningar fo?r elektrifierade lastbilar med eHighway inom svensk gruvindustri : En ja?mfo?relse av olika transportslag mellan Mertainen och Svappavaara

The Swedish government has a goal of achieving a fossil-free vehicle fleet in 2030. Heavy transport constitutes a significant part of Sweden's transportation sector and the vehicles are driven almost exclusively by fossil fuels. Siemens has developed eHighway, a concept for electric road systems enabling electrification of trucks, in order to reduce the environmental impact of heavy transports. This study aims to investigate the potential that eHighway has on transporting iron ore from the mine of Mertainen to a processing plant in Svappavaara. Electrified trucks are compared with conventional trucks, and diesel and electric trains.The evaluation was made with respect to energy consumption, environmental impact, and cost.

Farmers´ decisions factors : a case study

This study examined the factors influencing dairy farmers´ decisions to invest in automated milking systems (AMS). The problem studied involves uncertainty, information and complexity for dairy farmers in specific decision contexts. The frame of reference in the thesis combines contingency theory and decision theory and is used in a qualitative analysis of a set interview with dairy farmers who have recently bought an AMS and salespersons from Delaval, one of the AMS suppliers.The aim of this study is to develop an understanding of the decision making processes of dairy farmers, and in particular to identify which types of factors influence the outcome of an investment decision in the technological development of a farm.The study uses Thompsons` (1967) theory about the structure that organizations develop to handle the input of information. Thus, interest is focused on how a farm business structure handles information in the AMS decision, investigating the differences in information with Delaval?s "feed first principle" system and Lely?s "free cow traffic" system.The results of the qualitative interviews with the dairy farmers who bought an AMS show that there are three important factors that influence the outcome: employees, suppliers and the owner.

Handel med utsläppsrätter - hur företagsstrategier påverkas :

Climate change is one of the most difficult problems that humans have to deal with. Today, the evidence of human effects on the climate change and the rise of temperature on earth are strong. It is extremely important that all countries get together and cooperate in order to be able to solve the problem with climate change. One step in the work on climate changes is the Convention on Climate Change, which was agreed on in 1992. The Convention on Climate Change resulted in the Kyoto Protocol in 1997. The Kyoto Protocol is an agreement between a number of industrialized countries to limit or reduce the green gas emissions.

Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi

The incineration of waste is steadily increasing in Sweden and so is the production of ashes. The bottom ash has for many years been used as construction material in landfills. Now many of the nation's landfills are closed and there is a great need to find another beneficial use for the ash. Bottom ash is a gravel-like material and with its material properties it can replace natural gravel in parts of roads and surface constructions. Today this use is only approved within landfill areas where leachate is collected and checked.

Skydd mot nitrat och bekämpningsmedel i dricksvatten : åtgärder och styrmedel i fem länder

In many European countries there is an increasing concern about the occasionally high concentrations of nitrate and pesticides in drinking water. The advent of the EU Water Framework Directive particularly highlights this. The directive states that all large drinking water sources should be identified and protected from pollution before 2009 and that by 2015 all water bodies should reach a 'good status'. In Sweden about 60 percent of the drinking water sources have protection areas. This means that about 700 new water protection areas need to be designated before 2009. This will affect many farmers, restricting their farming practices. The purpose of this study was to investigate which methods are used in other countries concerning nitrate and pesticide pollution from agriculture. From this, the expectation was to generate ideas on what could be undertaken in Sweden when designating new protection areas.

Hur ofta bör småhus sotas? : En samhällsekonomisk analys av ändrade sotningsfrister

Sweden recently changed the national regulation of chimney sweeping. This study has two purposes. The first purpose is to evaluate the effect of this reform to see if the new regulation has led to an effect in terms of increased chimney fires in single-family houses and for the wood-burning and oil-burning stoves, respectively. The second purpose is an updating of a previous study (Mattsson 1994) of analysis of society´s benefits and costs of different alternative sweeping frequencies for wood-burning and oil-burning stoves. This study also has a secondary purpose to examine the extent to which the local sweeping rules vary with climate conditions.  Mattsson, based on his results, proposed that the sweeping requirements for oil-burning stoves should be reduced from twice a year to once every second year and for wood-burning stoves the sweeping should be reduced from four times to once each year.

PROKRASTINERING - gapet mellan avsikt och handling Studenter på högre utbildningar

The definition of procrastination can be described as a behavior with deliberate postponement of tasks or commitments despite expected negative consequences for the individual and his or her environment. This study examined how widespread this behavior is among students in higher education in Sweden. Using a web-based survey, data was collected for analysis. A statistical program, SPSS, was used for evaluation of the collected data. The purpose of this study was to examine whether there are differences in the degree of procrastination between students located on campus versus students who do their education at distance.

Kaffesump som substrat i biogasanläggningar eller som bränsle i fjärrvärmeverk : en studie av effekter på växthusgasutsläpp och kostnader

Each year, the coffee machines at Ericsson in Kista produce around 100 tons of ground coffee waste.The companies Coor Service Management, Löfbergs Lila and Selecta are all responsible for differentstages in the logistical chain in delivering coffee and, together with Ericsson, they want to increasetheir environmental benefit. The plan is to produce biogas through anaerobic digestion instead ofincinerating the coffee waste in a heating plant. The results are to be presented as different businesscases in which different biogas plants are compared with the reference case (heating plant),comparing costs and environmental impacts.There are two major environmental benefits from producing biogas; reduced carbon dioxideemissions from when fossile fule is replaced by carbon neutral biogas, and reduced emissions fromreturning digestate from the bio reactor to farmland instead of using industrial fertelizer.In order to determine the biogas potential in coffee waste, a couple of properties had to bedetermined in a laboratory. Properties such as the dry substance content, heating value, moisturecontent and ash content. The results show that 100 tons coffee waste could produce around 16 500Nm3 biogas which would contain 163 MWh.The biogas reactor and upgrade plant both need energy gas to function and uses around 14 MWh ofthe produced gas.

Importens påverkan på Etiopiens jordbruk : en välfärdsteoretisk analys av Etiopiens import från Europeiska Unionen

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.

Vibrationsproblem i närliggande konstruktioner i samband med markarbete

Ground work like blasting, piling and excavation has always had a great influence during the planning phase of a construction project since it can cause damages on adjacent buildings and have severe economic consequences. This thesis deals with how vibrations caused by ground work influence near-by buildings and what methods geotechnicians and construction entrepreneurs use to handle these risks.The purpose of this thesis is to explain risk management in relation to ground work. In order to achieve this I have used a qualitative method by interviewing a geotechnician and a ground work contractor who possess knowledge and experience useful to this thesis. The result shows that vibrations from ground work spread through the ground as seismic waves that cause displacements and packing in the ground visible in adjacent buildings as cracks and subsidence damages. Geotechnicians study ground work vibrations by means of ground investigations and experience from previous projects in order to produce a risk analysis that entrepreneurs can use to reduce damages.

Betydelsefulla faktorer för ensamkommande barn : En kvalitativ studie om faktorer som påverkar ensamkommande flyktingbarns liv

The aim of this study is to examine which factors in the receiving-country that have had an influence on three now adult unaccompanied refugee children. The method used in the study is qualitative interviews with the three above-mentioned participants. The results show that some factors are perceived as helpful, having a positive influence on the participants life while other factors are perceived as worsening, having a negative influence on their life. Depending on the context some factors such as age, the Swedish language and housing arrangements have had both positive and negative influences on their life. Positive factors are among other things: access to good treatment and support, help with processing trauma and bad mental health, help with understanding coherence, access to a social network, family reunification, resilience and other internal factors.
