Energianvändning på Volvo Lastvagnar Tuve
Volvo Trucks is the second largest manufacturer of heavy trucks, with factories in several countries and with around 21 000 employees. At the plant in Tuve, trucks have been built since 1982 and the activity mainly consists of producing side members and to assemble and packing kits of trucks. In 2005, the factory in Tuve launched the ambition to be the first carbon dioxide neutral vehicle factory in the world. This will be implemented by streamlining and investing in renewable energy. The aim of this degree thesis is to map the usage of energy within production, and also to prepare a method to measure key figures (use of energy per produced unit).
Tillsats av biokol till en svensk sandjord : effekter på lustgasavgång, kväveretention och andel vattenfyllda porer
In a column experiment the effect of three different biochars on nitrous gas emissions, nitrogenretention and water filled pore space (WFPS) were studied in a Swedish sandy soil, classified as aCryopsamment. Ammonium retention was positively correlated, while KCl-extractable ammoniumwas negatively correlated, with the specific area of the biochars. The question was raised whether thenegative correlation between extractable ammonium and biochar specific area reflects the amount ofammonium present in the soil or its extractability from the biochar, and whether methods forextracting soil mineral nitrogen, like KCl-extractions, have to be modified for application on biocharamended soils. There was a tendency of increased nitrate retention and KCl-extractable nitrate withbiochar and KCl-extractable nitrate was positively correlated with the specific area of the biochar. pHwas higher for all biochars compared with control, although the differences were not significant, andWFPS was lowered by biochar addition, significantly in one case.
Teknisk och ekonomisk analys av en bränslekonvertering vid SIA TallOils pelletsfabrik :
At SIA TallOil's pellets factory in Latvia wood shavings and saw dust are dried with flue gases from a gas burner. TallOil wants to replace the gas with a biofuel that is available at the pellet plant. The reason for this is the unstable gas market in Europe in combination with the fact that TallOil wants to improve its profile as supplier of renewable bio fuels. In this project the technical and economical possibilities for a fuel conversion to ether bark powder, wood shavings or wood powder have been investigated. These fuels should be burned in one of the following applications: TPS BioSwirl, VTS Multifuel burner or Saxlunds bio fuel combustion plant
Due to the fact that the fuel alternatives available are relatively common except for bark powder, the work has mainly been focused on bark powder.
Hur arkiverar Sveriges byggföretag? : Ett försök att finna arkiveringspraxis i en för kulturarvet viktig företagsbransch
What traces of their actions are the Building Corporations in Sweden leaving in their archives and are they followingsome archival policies? This thesis is trying to answer that question. For that reason 25 archives fromSwedish Building Corporations have been investigated concerning their size, contents and age. Furthermore apoll performed by the Swedish National Archives in cooperation with the Swedish Employers? Confederationhas been analyzed.
Mekanisering av häststall
Mechanization of Swedish agriculture started in the beginning of the twentieth century, to be able to have more animals without raising the number of employers. The horse business has not by far kept up with these cost savings solutions. Cleaning out stables and feeding horses are the most time-consuming tasks in horse stables today. The most common way to clean out the stable is still by shovel and wheelbarrow. The clean out process can easily be mechanized through semi- permanently beds with movable walls between the boxes so that the litter can be removed by a tractor or a loader.
Solenergisystem i Hammarby Sjöstad
Problems with the current energy system, which partially relies on non-renewable fuels, are increasingly recognized. Emissions of greenhouse gases from fossil fuels may speed up global warming, which in turn leads to a number of negative consequences. Nuclear energy is risky and relies on consumption of a scarce resource. This leads to a demand of renewable energy that is also economically feasible. One possible renewable source of energy is solar energy.
Hälsoproblem hos strutsfåglar i Sverige : litteraturstudie och sammanställning av patologifynd
In the beginning of the 1990?s ratite breeding for meat production was introduced in many European countries, including Sweden. The knowledge of ostrich farming and diseases of ratites is increasing internationally but is still often limited among veterinarians.
This report consists of a literature study and a summary of pathology findings from ratites submitted for necropsy to the National Veterinary Institute (SVA) in Uppsala, during 1995 to 2001. The purpose is to give a general introduction to ostrich and ratite breeding and to give an overview of the most common diseases.
The necropsy data from 1995 to 2001, indicate that many of the diseases are management related rather than caused by infectious agents. Due to cold climate ostrich breeders in Sweden need to supply well designed buildings and good care of the animal.

Täckning av plansilo :
With the increasing costs in concentrate the importance in producing ensilage with a high quality is becoming more and more important. To succeed with this goal it is of importance not only to harvest in the right period, but also to be able to store the ensilage without a decrease in quality and nutrional values. To maintain a good ensilage the covering of the ensilage must be carefully made. An unsuccessful covering causes mould to grow in the ensilage, which both increases the work load and also increases the amount of feed which is wasted. A bigger amount of spoiled feed also increases the risk of feeding spoiled feed to the cattle.
Mall förvaltningplan : Skolbyggnader
The aim of this thesis is to establish a ?förvaltningsplans? template to Fastighetskontoret in Vasteras city. Further general information about the mission was given at our first meeting with Rolf Haraldsson, who happened to be our mentor and works at Fastighetskontoret in Vasteras city.We agreed that using the software Excel was the most appropriate way to establish the template, because Fastighetskontoret also make use of Excel in their internal system, and also because Excel has a more friendly user interface and it is more easier to use compared to other software that have complex templates.One of the first things we did was to get in contact with different fastighetskontors around Sweden so that we could either take part of their ?förvaltningsplaner? or get referred to other material that could have been used. But this turned out to be an unsuccessful strategy.
Karlstad Vision 100 000 och dess implementering för Karlstads Elnät AB 2011-2015
The town of Karlstad has a long term project called Vision 100 000 which aim is to increase the population towards 100 000 inhabitants. This will of course put a strain for the town?s energy distribution grid. This is a work about trying to predict the grids power usage would be for the next five years if the city building plan is finalized. Those predictions are mainly going to be done through calculations with a database program called Facilplus and by checking the measured history of power usage per hour on certain selected customers by the program CustCom.
Luftfuktighetens påverkan på konstruktion och klimat i en berghangar
Aeroseum is an aviation museum located in an old military underground hangar. The ventilation system in the hangar is designed for the military purpose of the hangar. This design includes a solution with air flowing through the space between the construction of the hangar and the rock surface. The solution is intended to avoid a buildup of inflammable gases. This design leads too high humidity levels in the hangar.
Distribuerade fastighetsautomationssystem : - En implementation av kommunikationsprotokollet BACnet
Building Automation Systems in commercial buildings are often designed and installed by different contractors, using equipment and components from different manufacturers. The lack of an accepted communication standard has resulted in a few different standards. Many manufacturers of building automation systems only support one, a few or none of these standards, while developing proprietary system solutions. Regin, who develop such equipment, are planning to adopt an open communication protocol specially designed for building automation - BACnet. As a step in that direction this thesis was announced with the purpose to investigate the possibility to implement BACnet in one of their products and to gain more knowledge of the BACnet protocol.
Geotermi i Ungern : Undersökning av Ungerns energisituation inriktat på geotermi samt kapacitetsfaktorn för det största geotermiska värmeverket i Mellaneuropa.
Hungary?s share of renewable energy in 2010 was 7.9 %, and their renewable energy goal for 2020 is 14.65 %. Geothermal energy is one option that could help to achieve the goal, since Hungary has favorable bedrock, the temperature gradient is above average and thepermeability is high. Today Hungary is importing just over half of its primary energy supply. Because of political conflicts between nations Hungary wants to expand its own production of energy.
Miljökonsekvensbeskrivning för en utökning av befintlig djurhållning :
In the last few years the environment becomes more watchful, even for us farmers.
All agricultural enterprises that exceed 200 animal units must be tested according to
regulation of environment. A farm business with 200 animal units and more is classed
?environmentally hazardous activities? and has to make an environmental impact
assessment for the business you have today, and the activity after expansion.
Before you can construct a building and expand the numbers of animals is a lot of
applications to make. I have in this project restricted me to establish a environmental
impact assessment and a consultation foundation.
To make a environmental impact assessment is the big part of the application. The
environmental impact assessment take a lot of time and you need skills for all the rules
in the environmental code to be abele to make an environmental impact assessment
approved.
The environment codes purposes (1 kap 1 § Miljöbalken) is to rule the laws.
The purpose of the environment code is to promote sustainable development which will
assure a healthy and sound environment for present and future generations.
Definitions of a ?environmentally hazardous activities? 9 kap 1§ Miljöbalken) shall
mean the discharges of wastewater, solid matter or gas from land, buildings or structures
onto land or into water areas or ground water.
