Unwanted vegetation on the land of electric transforming stations is a problem, in the sense that it contributes to higher fire risks and also constitutes an obstacle for people performing maintenance operations at the station. Such unwanted vegetation is controlled using herbicides and mechanical measures. Since the use of herbicides implies environmental hazards, there is a need to find alternative ways of fighting the unwanted vegetation. Investigation into suitable plants for ground cover, trials in the greenhouse, trials in the field, soil analyses and compilation of experiences from similar trials are parts of this work. The paper also contains analyses of possible environmental benefits and economical gains. There is also a final discussion of some proposals regarding alternative weed controlling methods.

This report consists of  an anlysis of the imapct of a dam failure at Tjärnviksdalen in Ragunda, Sweden. The analysis is conducted using the EU model for environmental impact assessments, as well as a group interview. The presentation of the results in the form of a map  where the water level has been raised to the level that the County Board  of Jämtland considers to be possible in case of a dam failure.The result of this work is a detailed analysis of the consequenses that a dam failure would cause, the result consider everything from the direct consequences of the water column to an analysis of the chemical changes that the water would undergo.Parts of the analysis have shown that the purification centre and the old deposits will have the biggest impact on Hammarstrand. Both the purification centre and the deposits will realise chemicals to its nearest environment and because of the flooded purification centre the city will not have the ability to clean the water. .

[?If we zigzag in the middle, it?s OK?] The purpose of the following study is to examine the relationship between tourism and religion in a Balinese context. We look specifically at changes in religious practice, culture and mentality, as well as how religious philosophy is used as a tool for limiting the negative impact of tourism. The methods used are semi-structured interviews and participant observations. Central themes in the following essay are globalization in the form of tourism, westernization, subsystem theory and capitalism, which also make up the theoretical framework.

This master thesis deals with two case studies in environmental archaeology and battlefield archaeology focusing on two major events in the late history of the Swedish coastal town Umeå and its nearby village Sävar. Established in the early 1600's, Umeå was known for its export of timber and import of cereals. The town has suffered from numerous fires, the fire in 1888 being the most devastating. Few written records of the town remain from before the 1900's. The latest war in Sweden's history is documented in historical sources and took place at Krutbrånet, Sävar where the Swedish troops suffered defeat against the russian forces in 1809.

The environmental requirements and laws on combustion engine emissions are very tough today andthey will become even more stringent in the future. To achieve these requirements there are highdemands on the control systems for these engines. An improved precision in the measurement of anengine's speed and position gives the electronic control system an even better timing when it comes tofuel injection and ignition. This makes the engine more fuel efficient, reducing the emissions. This thesisis part of a collaborative project between Hoerbiger Control Systems and subsidiaries.

Hudiksvall Municipality will build a new preschool. The goal is that the pre-school should reflect the municipality's environmental goals and meet building regulations. The wall structures that are compared in the report is an insulated wooden frame and a frame of lightweight concrete blocks from H + HWall structures are compared within the areas of U-values, air tightness, thermal storage capacity, fire ratings, moisture, durability, emissions and environment. In these categories the two wall structures will be rated in a scale from 1 to 5 and then the categories are weighted against each other. The weighting is based on Hudiksvall Municipality's assessment of the categories importanse for their final selection.The results of the comparison show that the concrete structure is recommended for the construction of pre-school with 27.55 points against the wooden structures 23.70 points.

The purpose of this essay is to study and compare the air traffic with the train traffic between Gothenburg ? Stockholm. The study is based on three different perspectives: travelling time, travelling cost and the environmental effects. With those three factors included in the study, it will be more useful to determine if the unnecessary travel exist.This essay is based on quantitative information which has been gathered from the booking system of the train- and airline company?s websites.

To curb greenhouse gases and mitigate climate change is one of the biggest challenges human society face today. Carbon dioxide (CO2) has accumulated rapidly in the atmosphere as a consequence of burning of fossil fuels and deforestation. The aim of this study is to explore two methods to store carbon dioxide in geological formations and biological sinks. The aim is also to discuss the two mitigation options from a sustainable perspective and whether it can lead to a better environment and benefits for local and global societies. The research questions are: Which method to store carbon dioxide, geological or biological, is the most effective? Which method to store carbon dioxide, geological or biological, has the greatest potential to promote sustainable development for local communities?The method used is a comparative case study and presents four case studies that explore the potential for CO2 storage offshore in Norway and Brazil; and in tropical forests in Mexico and Brazil.

The decrease in the number of dairy farms in Sweden has been ongoing for a longer period of time. But the fact is that this has previously not had any big effects on total amount of milk produced in Sweden. The main reason is that the remaining dairy farms get larger. However, during the past year, there has been a decrease in the total amount of produced milk, because the decrease is faster than the increase within the farms that are left. During the same period of time the supply of milk on the global market also has decreased. In spite of the fact that the global supply have decreased and the fact that the milk price increases, there are dairy farmers in Sweden who chose to exit the market.

In 1993 Sweden introduced a new Forest policy, with a larger freedom of action for the forest owners, but in the same time the forest owners are expected to take greater consideration of the forests and the environment, that is required by the law. This is necessary to be able to obtain the goals of the new policy. Therefore the demand for competence and guidance is larger than before. At the same period of time organisations where slimmed and trimmed during a economic recession and the question is how this has affected the number of employees on different levels in the organisations, the competence of the employees and their internal education and if these changes affects the possibility of implementing the forest policy. This study contains three points in time where measures were made, 1990, 1995 and 2000.

The purpose of this thesis is to identify and define Key Perfomance Indicators (KPIs) and value adding services which are used to describe the quality of Forias logistics services from different aspects. The KPIs should be attractive to both Foria and their customers, with the aim to strengthen the interaction between both parties.The basis for this work is a research in which a literature review and a survey of the market for Swedish logistic service providers were carried out. An analysis of the present situation of Foria was carried out, where a number of people in the company were interviewed. These elements were used together with definitions of KPIs to perform the analysis of the work.The result of the work is ten KPIs that have been created and developed for Foria and which are considered to be attractive to both Foria and the selected customers. The KPIs are: · ECO-driving (binary) ? the company has ECO-driving-educated drivers· ECO-driving (comparison figure) ? all drivers individual driving and its resulting exhaust emissions are compared· The environmental impact ? a total of exhaust emissions from all vehicles belonging to a single business, measured in tonne-kilometres· Complete order ? portion of fields with accurate information (in an order), with the possibility of error categorization· Delivery reliability ? time difference between expected and actual delivery, average for all orders· On-time ? the number of days and hours of difference between the expected and the actual time, for all activities of the order· On-time (activity) ? the number of hours and minutes of difference between the expected and the actual time, for each individual activity of the order· Divergence ? a categorization of all causes of divergence and its responsible department· Level of integration ? the level of cooperation between the logistic service provider and the customer· Customer satisfaction ? how well an order will meet the expectations of the customer The KPIs are described in detail with definitions, how they can be used and what is required to implement them in the service process of Foria.

Denna uppsats vetenskapliga grund hämtas främst från ekofeminism med tanken om jämställdhetsarbetets samband med miljövård, samt närvarons politik med teorier kring representationens betydelse för den politik som förs. Ekofeministisk teori menar att det finns betydelsefulla samband mellan förtrycket av kvinnor, icke-vita människor, och fattiga på ena sidan och den icke-mänskliga naturen på andra sidan. Detta innebär att kvinnor på ett bättre sätt förstår det förtryck som finns mot icke-mänsklig natur än män. Teorin om närvarons politik menar att det styrande idéfokuserade politiska systemet går miste om viktiga perspektiv och kunskaper som en mer representativ politik kan ge. Närvarons politik utgår från att politiskt underrepresenterade sociala grupper kan bidra med perspektiv och kunskaper som annars förblir ohörda.

För att ett företag ska kunna hålla sig flytande på marknaden idag krävs de att de har hundra procent koll på vad som sker i deras fabriker och att de strävar efter en mer hållbar tillverkningsprocess. Att försäkra konsumenterna om att fabrikerna inte använder sig av barnarbete eller dåliga arbetsförhållanden räcker inte längre utan det krävs en bredare kunskap inom miljö och hållbar utveckling för att den trogna kunden ska stanna. Syftet med denna rapport är att kontrollera det nyuppstartade företaget DENIM IS DEAD?s produktion och utvärdera om hur man kan förädla de olika processtegen samt skapa transparens gentemot kund.Metoden som arbetet utformades efter var genom en fallstudie som är baserad på en mestadels deduktiv metod men med inslag av induktiv metod. Där grunden lades genom en utförlig faktainsamling för att i rapportens senare del kunna analysera de hypoteser och problemformuleringar som ställts.Målet med rapporten var att ta fram en metod eller produkt som ska underlätta kommunikationen med DENIM IS DEAD?s kund.

Denna rapport är resultatet av ett examensarbete utfört vid Institutionen för industriell och ekonomisk utveckling vid Linköpings universitet på uppdrag av konsultbolaget Sustainia AB. Lean produktion, ofta benämnt Lean, har det senaste decenniet blivit en allt mer attraktiv produktionsfilosofi för att minska kostnader och öka kundnöjdhet genom förbättrad leveransservice och effektivare flöde. Ett flertal författare har påpekat att införandet av Lean direkt kan förbättra ett företags miljöprestanda, främst till följd av det minskade slöseri som Lean avser ge upphov till. Vidare finns studier som visar att vissa möjligheter till förbättringar och kostnadsbesparingar riskerar att gå oupptäckta om verksamheten ses ur ett strikt Lean-perspektiv. Med ett miljösynsätt finns dock chans att dessa blir upptäckta.
