Avfallsdirektivets påverkan på efterbehandling av förorenad mark

The purpose of this report is to increase the awareness about the problem that occur when the waste hierarchy is applied to management of contaminated land. The work with remediation of contaminated land in Sweden is part of the efforts towards reaching the national environmental objectives. Therefore a subsidiary aim is to analyze how this influences the prospects of reaching the objectives. The work consists of two parts; a case study and a comparative literature study that focus on England, the Netherlands and Sweden. The case study is intended to provide a practical perspective through a comparison of the climate impact from two methods.

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.

Elevers syn på klimatfrågan : Klimatundervsiningen i skolan

The aim of this study is to find out in which way the education about climate in school is taught and how the students experience the world situation today. There are various theories about the greenhouse effect and its origin and these theories should be addressed to ensure that students get a broader understanding of how climate change occurs. This includes the natural phenomena and also the human impact on climate change. Students in school are a source of concern that only human are the cause of global warming, and know little or almost nothing about the natural phenomena of global warming.  I will mention what has emphasized in the national steering documents in the case of environmental education at school.I have used a qualitative method, where interviews and document analysis were used as techniques. The interviews took place with five students in ninth grade and with three science teachers in the same school..

Klimat & Patriarkat : Genusgeografi i Huddinge

The essay deals with gender aspects on climate change adaption. The aspects consist of the fact that women in Sweden drive cars less than men, and that women in the developing world are more affected by natural disasters arising from global warming. This study was carried out in the municipality of Huddinge, a suburb to Stockholm, by interviewing one Agenda 21 coordinator, one planner and one student in genderstudies. I also attended a meeting in the Committee for built environment in the Huddinge Municipality, to ask the politicians questions and observe gender structures during the meeting. The results also consist of a search for gender-related words in the documents used in the essay.The results are analysed using ecofeminsim, a theory that connects woman subordination and environmental destruction.

Dendroklimatologisk analys av lokalklimat vid Grövelsjön i Dalafjällen

Climate on earth is getting warmer, which effects earth?s energy balance and so forth the ocean and atmospheric circulation.  In many sub-polar regions on the northern hemisphere changes due to warming of the climate can be observed. Some examples that already have been observed are shifts in tree line, towards higher altitudes and latitudes, increased ablation of Swedish glaciers and melting of the permafrost on the Siberian tundra. In Sweden climate change scenarios tell us that it will become warmer and that a higher amount of precipitation in form of rain will be an effect from this. To study climate changes in Sweden, transition zones are useful in order to observe changes in distribution of species and animal populations.

Investeringskalkyl för en ny såglinje : en rapport om investeringskalkylering

This report presents an investment calculation based on an assumed initial investment of a new saw line to an existing sawmill. In order to get as close to reality as possible, we have received data material from northern forest owners who recently made an initial investment in their sawmill in Kåge. In order to calculate and evaluate investments are several different methods, but we, we have chosen to use the discounted cash flow method. The method sums up with the help of a fixed cost of capital together with any future costs and revenues, thereby giving a present value of the investment. We also do a sensitivity analysis to examine how selected factors affect the investment research they change. The study is carried out to a fictitious investment, and therefore the result should not only be studied as a result of the figures. The purpose of this study was that with the help of an investment calculation studying the profitability of a hypothetical investment, and by means of a sensitivity analysis to study the sensitivity of investment to changes. The result demonstrates that the calculations according to the present value method requires a lot of information of the prospective investment.

Höjning av vattennivån i Mälaren : Ett hot mot Stockholms centrala delar vid en framtida klimatförändring?

In today?s World is climate change an important and hot topic. Climate scenarios for Sweden show a warmer climate, especially during the autumn, winter and spring. The same climate scenarios also show that the precipitation will increase during this part of the year, however, during the summer the opposite is expected to occur. The purpose of this essay is to examine how future climate change will affect Stockholm especially the expected increase in precipitation, which may lead to a rising level of the Lake Mälaren. During 2000/2001 was Stockholm hit by a flood. This flood nearly resulted in major consequences and showed that there were significant risks for the city of Stockholm and increasing precipitation will result in even more water in the drainage systems of Lake Mälaren. The results presented here show that it is important to increase the drainage capacity of Lake Mälaren in order to reduce the risks of flooding in the central parts of Stockholm.

Köldbryggor och energiförluster. En studie om energiförluster genom balkonginfästningar och deras betydelse för byggnadens totala energibehov

In this report the balconies? abutments for a property in Bo01-area in Malmö has been studied. The property which is called Vitruvius contains four build-ings where two of them have corbelling balconies with intermittent abutments. With intermittent abutment means that the 50 mm thermal bridge insulation that the balconies is equipped with, is broken regularly by a 300 mm concrete heel. The reinforcement bar that holds the balcony runs through this heel.

Påbyggnad av våningsplan medlättkonstruktion : En jämförelse av stommaterialen trä ochtunnplåt

The purpose of this thesis is to examinethe possibilities for adding a floor to anexisting building using the two materialswood and sheet metal profiles as the loadbearing structure. An apartment buildingfrom the 60s has been used as referencehouse. Two different suggestions for thedesign are presented in the rapport. Oneof them has been analyzed with wood andsheet metal as the load bearing structure.Using the old constructional calculationsand blueprints of the existing buildings,the load bearing capacity has beencalculated. In the calculation programFEM-Design the building has been testedwith the loads that an extra floor wouldgive.

Kombinerat system för ventilation och rumsuppvärmning : Parameterundersökning i simuleringsmodell för takvärmesystem

A large amount of our time is spent indoors in an artificial climate. To make the experience pleasant there are requirements on the ventilation and the heating system. At the present time the most common form of heating is a radiator system complemented with a ventilation system. A ceiling heating system with combined heating and ventilation can replace the two separated systems. The benefit with a ceiling heating solution is that it saves space since the radiator system is no longer needed.

Försämrad korrelation mellan storleken av Kebnekaises sydtoppsglaciär och andra klimatindikatorer

Intergovernmental Panel on Climate Change (IPCC) recognizes glaciers as the best land-indicator of climate change. A variety of studies have concluded, using both modeling and field studies, that above all climate parameters precipitation, particularly winter precipitation, and summer temperature controls the change in glacier mass balance. With global warming almost all glaciers on Earth are losing mass. In this study, the summit-glacier constituting Kebnekaise's south summit (called the Southern-summit henceforth), Sweden's highest point, is studied to see how it is affected by winter precipitation and summer temperature during the period 1968?2013.

Underhållskostnader på rundbalspressar :

Costs of maintenance on agriculture machines is something that many farmers has a low knowledge of, it can depend on low interest or that the farmer don?t have enough time. To make it easier for the farmers they can use many computer programs which are available on the market. In this program they can calculate their costs of maintaince on their agriculture machines, for example STANK and JTI machine calculation program. Most of this program is using Svensson (1987) costs model whish was made in Sweden in the middle of 80 decade in a large study.

Beräkningsmall för väggskivor enligt Eurokoder

The regulatory framework for constructional calculations in Sweden did expire In January the 1.st, 2011.Since then the constructional regulatory that originally were composed by Boverket (BKR) has been replaced by new common range (Eurocodes) for the entire European Union. This transition has led to changes in existing rules and standards regarding dimensioning area in Grids and has forced a need for updating to structural Engineers.The new calculation system has caused time-consuming studies of the new rules and a proper understanding of all the advice and regulations for the entire profession.This study has been carried out in cooperation with the firm "Knut Jönson Ingenjörs AB i Stockholm?, that has been affected by this transition as all other consulting firms. The firm has requested for a calculation method of wall beams according to Eurocodes. The study's focus is therefore to clarify the rules and guidelines regarding the design of wall beams according to the new regulation.

Water balance and nitrate leaching from arable land in a changed climate : a model study

This thesis aims to present the essential background on how to perform climate changeimpact assessments, and to present the results from a climate impact assessment on waterbalance and nitrate leaching for an arable Swedish soil. The soil is a sandy soil in southwesternSweden, grown with spring cereals. This study is meant to be a benchmark example,and cannot be seen as a regional or national assessment for Sweden, rather as an approachto present and analyze the most important parts of these kinds of assessments.A dynamical simulation model (COUP, Jansson and Karlberg, 2004) was used for thisstudy. The model was parameterized and calibrated against data from an experimental site,located in Mellby in Hallands county, south western Sweden. Measurements were carriedout between 1st of April 1988 and 1st of April 1991.

Analys av systemfaktorers påverkan på tillförlitligheten i distributionsnät

In this master thesis outage statistics covering tree years from two distribution grids are analyzed with the purpose to deduce which factors yield outages. The statistics are extensive therefore allowing in-depth analysis of both customer and system related factors. From this starting point and as a model of explanation energy not supplied is studied as the consequence and the measurement of the inconvenience caused by outages. Different methods for calculating energy not supplied are developed and studied and put in comparison to the method used in Network Performance Assessment Model, which is the Swedish frame work for regulating electricity distribution.Analysis of the outage statistics show a relation between the type category of customer and outages that can be deduced to the variance and the density associated with that customer category. Prioritization of different customer categories is elevated also in this aspect.
