In this study I have compared two systems of handling TMR, self-propelled/ self loading mixers and conventional towed mixers, what has been investigated is the time for filling, mixing and feeding TMR as well as maintenance and fuel consumption. The background of this study is the structural rationalization within the Swedish milk production that has put focus on efficiency and reducing of costs. Forage and labour are the two biggest costs in milk production today. The study has been performed by visiting three farms and with a stopwatch measured the times for filling, mixing and feeding TMR. At the time for the visits, the users have been interviewed regarding maintenance and fuel consumption. They have also had an opportunity to give comments of how they experience the mixers. The result of the study after processing is that the average stock in the study can save 74000 SEK a year by reducing time for filling, mixing and feeding TMR to cows with a self propelled/ self loading mixer . The conclusion I can make of this study is that it?s not the size of the stock that decides whether it?s interesting to invest in a self propelled/ self loading mixer, but the presumptions on the farms, for instance forage logistics and mechanical equipment..

Organisation and market orientation of elderly careThis comparative literature study is intended to describe how elderly care is organised and financed in Germany and Sweden. Furthermore, it analyses the degree of competition and market orientation in both countries' care systems. Important aspects in this context are the kinds of measurements which are used on the two markets and the question if there are quasimarkets.The theoretical backgrounds of the study are Esping-Andersen's "Three Worlds of Welfare Capitalism" and Harold Wilensky's convergence theory. Esping-Andersen's theory describes Sweden as a social democratic and Germany as a conservative welfare regime which means that there are different conditions for the development of welfare. The use of Wilensky's theory shows that both welfare systems are converging since the end of the 20th century.

This thesis has been focused around the Diels Alder reaction with the goal to design an enzyme catalyzed reaction pathway. To achieve this goal computer aided enzyme design was utilized. Common traditional methods of computational chemistry (B3LYP, MP2) do not do well when calculating reaction barriers or even reaction energies for the Diels Alder reaction. New calcu- lation methods were developed and tested. This was the focus of the first part of the thesis, by choosing a small system, extensive and heavy calculations could be done with CBS-QB3.

In today?s society the average person is flooded by information from everywhere. This is in particular the case when using the Internet; consider for a moment the fact that a decent search engine at this moment scans 8 058 million homepages. For a user that repeatedly comes back to the same site, the case is often that they know what they are looking for. The problem is to isolate the important information from all the other information embedding it.We would like to state that we have found one possible solution to this problem, where the user himself can define what information he is looking for at a specific server, then scan the server when visiting it with his browser.

 Prostitution has been intensely debated in Sweden for nearly four decades. Two major investigations have so far been initiated by the government and numerous propositions have been put forward in the Swedish parliament resulting in the sexköpslag from 1999 that criminalizes purchase of sexual services. The law aims at punishing the buyer and protecting the women in prostitution, thus making it possible for women to be helped by various social interventions rather than punished. Swedish society has undergone major changes in these decades. Globalization, the internet and the membership in the EU have changed the Swedish society and influenced the discourse on prostitution.This paper has a twofold aim, on the one hand investigating if and how these changes have had an impact on the prostitution discourse in texts produced by the government and analyze how female and male sexuality in connection to prostitution is constructed.

The purpose with this essay is to study police students perception of men?s and women?s role taking and behavior in a group. The question that is presented is if a group?s efficiency can depend on which gender the members of the group have. There are many theories about the concept male and female and the meaning of these words.

This essay focuses on different aspects of the concept of freedom of speech. The purpose is to examine the opinions and thoughts that upper secondary school students have on rights, responsibilities and limitations when it comes to freedom of speech, and to investigate theirschool experiences of the mentioned freedom. Focus groups have been used as method and two group interviews have been conducted, one at a vocational and the other at an academic upper secondary school. Overall, nine students from the third grade participated in the interviews.The essay's results show that the students believe that everyone in society should have theright to be heard, whether you have extreme or divergent opinions. The interviewed studentsexpresses that all people have great responsibility for their opinions, however that, opinionsdiffer on how to interpret the concept of responsibility.

Earlier studies shows that democracy within the preschool is an important and on-going work, but could implicate certain consequences. For example that goals regarding democracy and influence in the preschool, rarely is done in practice but instead remains just words on a paper. It could also mean that the pedagogues lack education and knowledge within the area, but also how they react to the influence of children. Preschool is expected to be a place for all children, no matter what luggage the child is carrying. The luggage is filled with the life experience, the personality and in this case the needs that the child has. The needs could be anything from nearness to physical and psychological disorders that requires more pedagogical attention.

The aim of this study was to find out if hypertext structure has any relevance for the efficiency of information retrieval. An experiment, in which three variants of hypertext structure were compared, was carried out in the autumn of 1998. Three websites with different structures were constructed for this purpose: a sequential version, a hierarchical version and a webcluster version. 44 subjects, all students at the University of Lund, were randomly divided into three groups. Subjects were requiered to answer a number of questions using one of the three versions.

With the purpose of finding the motives behind use, production and reuse of Open Educational Resources (OER), the writer has conducted a qualitative survey. The three main questions in this two years master?s thesis are:? Why do people use others? unmodified OER?? Why do people produce OER?? Why do people alter and reuse OER?The theoretic framework is built around Manuel Castells? network society, with its social and efficiency seeking dimension, along with the Knowledge commons. Some pedagogy is included as well.A web survey was distributed to 796 users of the Connexions OER repository. 95 responses were received.

The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

This thesis investigates in which way principles and theories of usability is revelant when evaluating interactive systems for children aged 10-12. It also investigates whether there are specific factors that you should keep in mind while developing interactive products for the targeted group.The results of the qualitative study shows that priciples and theories of usability is relevant when evaluating interactive systems for the targeted group. However there is one concept that is more significant than the others. Our study shows that our targeted group is sensitive to time-consuming activities such as loading times etc. which has to do with the efficiency of the system.

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.
