The agricultural sector is currently highly dependent on fossil fuels, with diesel beingmost prominent. There are however both historical and modern alternatives thathave not been subject to enough evaluation to disregard them as suitable alternative.This report aims to theoretically investigate the feasibility of converting aconventional diesel driven tractor to run on electricity, delivered via a cableconnected to either the main power grid or on-site electric production, such asphotovoltaic. Delivering electricity to the machine via a cable is a method withhistorical roots in the early 20th century and in the present day mining industry.The economic and technological potential of the technique are evaluated, along withthe examination of several different motor powers, voltages, losses and constructionideas. The report finds the technique to be both possible as well as long termeconomically and environmentally beneficial. To realise this method however, somedeviations from the present methods of agricultural farming must be made,considering the more advanced driving patterns, the limited mobility and therequirement for extra driver awareness.

Urbanization has for a long time been a threat to our biodiversity. Epiphytic organisms such as lichens have been negative affected by traffic pollution and the new urban environment surrounding their old habitat (van Her 2001). Another epiphytic organism is the green algae Desmococcus olivaceus. Unlike lichens the green algae is favoured by polluted areas. The aim of this study was to investigate if time in urban environments affected the cover of the green algae on old oaks.

My purpose with this study was to research how a few teachers work with the children in preschool class to achieve a group that the children feel safe and comfortable with. Every human being has got the need to feel safe and with this study I want to illustrate the importance about working to achieve safety for children in preschool class, and environment that is new to them. In order to try to get answers to my research questions I have interviewed five preschool class teachers. The results showed that the teachers work in a way that makes the children feel safe by helping them establish the daily routines and common rules for the preschool class. They also let the children in the preschool class get to know each other and other children in the school by play and shared activities.

This thesis focuses on the problems involving immigrants and their voting behaviour in Sweden. We presuppose that immigrants vote in a far less extent than Swedish citizen according to general statistics. We try to explain and give solutions to this problem. To our help we use both integration theory focusing on multiculturalism and electoral participation theories.Starting off in these two theories, we have further analyzed a number of policies issued to solve the participation dilemma. The policies were issued in order to elevate the socio-economic standards, inform citizens and close the distance between voters and politicians.Our results show that what work best is long term ventures aiming at integrating immigrants to the Swedish society.

"What's feminine about the Women's library?" This library, Kvinnobiblioteket, is abranchoffice at Björkskatan in the city of Luleå, and the introducing question is thestartingpoint of this essay. To find some possible answers is its object.One way of describing what's feminine about Kvinnobiblioteket is through presenting itsobjective, ambitions and methods of working. That is done mostly in a chapter headlined"Kvinnobiblioteket", and shows how the women's perspective concerns for exarnplepurchase of books and magazines, displaying of books, the opening hours, design etc.Although the focus in the survey is not in the former kind of description, but in the interviewsbeing made during a two week long period of time with ten women at Kvinnobiblioteket(both library user and personnel) at spring 1995. The results of the interviewsthen have been compared with theories from psychological-, feminist-, literature- andlibrary and information sciences, as we11 as to former surveys and essays.The material together leads to some keywords that seem to be important when trying tofind out what's female about the women's library.

Information handling has been a key issue for different companies for a long time. Electronic Data Interchange (EDI) is used to transfer different business documents from one company to another. This is done in such way that the information itself is separated from how this information is stored and handled in the companies internal systems. As different companies have different systems there is a need for a standardised format for this exchange. There is a big difference between EDI-systems based on what kind of EDI-standard is used. The most common standard in Europe is EDIFACT, but with increased interest of using the Internet for business communication there is a need for a standard that is adjusted for use over the Internet.

The Swedish building stock accounts for nearly 40 percent of the total energyconsumption in the country. Properties built today are likely to last for 100 years orlonger. This places high demands on long-term and smart energy solutions that willkeep the future Swedish building stock energy consumption at low levels. This thesishas focused on examining how the energy performance of buildings is affected bydifferent choices of window types in different cardinal directions. The objective wasto obtain a basis for recommendations on how window properties can be optimizedfor different types of buildings and orientations.

Service Design is a relatively new, unexplored and exciting phenomenon that through an interdisciplinary work methodology designs services. A discussion has been going on for a long time regarding whether there is a difference between products and services. Services are often classified as immaterial, heterogeneous, non-storable and inseparable in relation to products. A question that arises is if something specific characterises the work methodology used regarding service design. The aim with this paper is thus to explain the work methodology when working with service design.

Our planet is faced with enormous challenges as the extreme weather events related to the human-caused climate change continue to gain strength. The scale of the problem has made changing human behaviour the central focus of sustainable development, and both public and private sector are expected to gain relevant expertise and introduce this work in their agenda. Over its 40-year history, social marketing has become an established field providing tools for social change, but compared to health promotion, sustainability has not been a major focus of social marketing research so far. At the same time, sustainable lifestyles are embedded in complex systems where both individual factors and those of physical and social environment play a defining role in their adoption. Communities are a good example of such environments, and they became the key focus of Community-Based Social Marketing, which combines different insights from psychology to suggest a step-by-step framework for crafting behaviour change campaigns. However, it has not been applied to larger and diverse communities, like cities, and has not focused on sustaining new behaviour over time, which is crucial for creating sustainable lifestyles.

Hösten 2005 inleddes ett större förändringsarbete på de kommunala skolorna i Trelleborgs kommun. Visionerna med projektet, som döpts till ?Spjutspetsskolan?, innebär ett nytt sätt att arbeta i skolan för både lärare, elever och föräldrar. Målet med projektet ?Spjutspetsskolan? är att minska det antal elever som går ut grundskolan med otillräckliga betyg.

The thesis is about integration in the city and how integration can be improved through physical planning. Segregation can result in changing peoples? prerequisites in our society. Opportunities in life become dependent on what area of the city you live in or where you grew up. Integration denotes acceptance for all people, while different cultural and ethnic identities are preserved at the same conditions for everyone.

With the end of the Cold War the number of conflicts where the United Nations have intervened has increased dramatically. This has entailed a need for a burden-sharing between the UN and regional organizations regarding management of conflicts. The aim of this study is to make a comparative analysis of the effectiveness and the efficiency in the efforts undertaken by ECOWAS and the UN during the civil war in Sierra Leone, through using theories on conflict resolution and the advantages of regional organizations in conflict resolution.My conclusion is that both ECOWAS and the UN were quite successful in managing the conflict and had an impact on the resolution of the war, although both peace operations suffered from internal problems. ECOWAS was effective in managing the conflict and in its mediating efforts as an insider from the region. The UN was more efficient in managing to attain their goals.

High quality within a Lean production system begins with standardised work, which creates stable processes able to generate predictable output. If nonconformity from the standard procedures occurs, routines are needed to analyse, correct and prevent the nonconformity from occurring again. In that way, the nonconformity can be a trigger for continuous improvements toward more stable processes. In takted production lines, where the operator follows a standard sequence with tasks set to be completed within the takt time, a nonconformity leads to downtime in the operator?s sequence, and no value is added.

The aim of this essay is to investigate the implementation of The Social Orientation inSweden. The Social Orientation is a part of the new, one year old, establishment law and isaimed at all newly arrived refugees and immigrants. The aim of the law is to help establish allnew arrivals into the Swedish society by providing knowledge about life in Sweden. Theeducational program is at least sixty hours long and covers: the public authorities in Sweden,laws and regulations, work and education, healthcare, children and family issues in a person?smother tongue.In order to achieve my aim I have chosen two questions: How has the law been implementedin Swedens three counties: Stockholm, Sörmland and Uppsala? What conditions are there fora successful implementation?In order to answer these questions I have used the traditional, ?street-level bureaucrats? andnetwork perspectives and issues for my study of implementation.
