The poultry red mite, Dermanyssus gallinae, is a common problem in poultry facilities, causing great discomfort for the hens and effecting the production economically. Few efficient acaricides are available and there is a need for new control methods since resistance has become a problem in some cases. The aim of this study was to evaluate the efficiency of the new liquid silica control agent Ectopar, on the poultry red mite. An initial in vitro test of Ectopar and its two components individually was performed, where live mites were sealed in together with filter paper impregnated with one of the three solutions prepared. The survival of the mites was thereafter recorded repeatedly during a period of 120 hours and compared to a control. For the field study, two poultry farms with different housing systems were used, one with furnished cages (farm 1) and one with a single tier floor system (farm 2).

The aim of this thesis is to examine how secondary teachers in the subject of history are using the textbook in their teaching. Four questions are being dealt with in this thesis. What importance is being placed on the use of history textbooks by the secondary teachers? What priorities do the secondary teachers have? How do they deal with student interests? And what is the importance of the secondary teachers? work experience? I have interviewed four secondary teachers with different work experience to complete this thesis. A Dictaphone has been used in all the interviews. Research has shown that textbooks now have a central role in teaching and the lack of alternative materials and reduction of teaching hours has made it difficult to replace. The main conclusions of the thesis are that the history textbook has a dual role depending on the teacher you ask, and that the history book is used differently by the teachers.

The purpose with this essay is to give the reader an insight into and to describe the Danish Work Environment Act in its current wording and then compare it with the Swedish Work Environment Act. The first part of the essay describes the Work Environment Act and after that I compare with the Swedish Work Environment Act. At the end of the essay I will give my own thoughts of the result of this essay. I have chosen not to describe some of the chapters of the Act, for example the chapter about technical means and materials, because of the less importance for this essay and of my own interest. I have also chosen not to make mention of individual professions.

The goal of this work has been to search historical materials, to identify the park's historical development, to prepare proposals on measures and that work should be the basis for further research. The aim has been to train us in searching for and use of materials and to gain an understanding of the process of work with older plants. In the process we have sought and found materials in archives, through literary and oral sources, and email contacts. Because of its excellent location perched on an islet in the low landscape Näsbyholm was long a fortress. The old castle on Näsbyholm was from the late 1400s but the site was fortified much earlier.

This study focuses on two text books, Magasinet and Ess i svenska, both common teaching material in Swedish schools. Since Swedish school system recently got a new curriculum and grading criteria, the purpose with this essay was to see how well the teaching materials used in school match the new documents.Since the subject has not really been studied before, the chapter containing recent studies focuses on layout, appearance and contents of good teaching material. The survey that I have implemented includes studies of the two text books, with comparison of the new curriculum, grading criteria and previous studies of what makes a good text book.Conclusions were that Magasinet is very comprehensive and match the criteria and curriculum very well, even though it spans over four classes and has to cover a lot of information. However, since it covers so much information, each section sometimes feels not as thorough as it perhaps should have been. Ess i svenska on the other hand, is a good complement to use in ninth grade, if you have studied the previous books for seventh and eight grade in the series.

It is semi-structured interviews with workers from the public employment service and the refugee reception. Information materials and evaluations that various authorities have made have also been investigated.The study concludes that it is important that the directives are clarified and that a new local and regional agreement will be established on paper.

The title of this thesis is ?Accessible Landscape - boardwalks in nature areas?. The main purpose of this thesis is to show how you can increase the accessibility for disabled people by constructing boardwalks in nature areas. The platform for the thesis is a study of litterature on boardwalks, accessibility and disabilities. After defining these terms I made three excursions to three different locations in the south of Sweden. During the excursions I evaluated the boardwalks situated in each of the areas through preferences such as the construction of the boardwalk, its design and the accessibility. After the excursions I interviewed managers of the areas I visited, and people working with disability questions in the municipalities where the excursions took place. To know how to make a boardwalk accessible you need to have knowledge about certain concepts, rules and recommendations. My thesis deals with aspects such as: *Accessibility *Disability *Rules and recommendations when building boardwalks *Real life - evaluation from the excursions and interviews with the managers The result shows that accessibility is a hot topic in Sweden and a lot of improvement is being done with fi nancial support from the European Union.

In July 2010 the curriculum Lpfö 98 was readjusted and was enhanced with new chapter, and the purpose of this essay is to study how preschool teachers discuss and describe how their conduction to the new chapter 2.6 of the readjust Curriculum Lpfö 98. I want to understand how they experience their work with the documentation.My question formulations are:How do three pre-school teachers reason around what they document in the pre-school?Which practical conditions do the pree-school teachers claiming to have on the pre-school to perform the documentation?How do they describe that they use the documentation to advance the tutoring in the preschool?In order to find out more, I interviewed three pre-school teachers, and analyzed the results I got based on prior research on documentation, and quality in preschool. My results show that the main focuses for documentations are how the children interact with each other, how they react and behave with new materials or activities. My informers emphasize that the main purpose of documentation are to be able to show the children their own process of learning.The practical conditions differ among my informers, which can lead to consequences when they want to make documentation and/or use the documentation for its purpose.  My results also indicates that the documentations are used to plan the pedagogical activities in regard to the children?s interests and according to the curriculum Lpfö98 rev.2010.

AbstractThe purpose of this survey is to examine how educators work with reading- and writing-skills in preschool with six year old children. I want to examine if the new curriculum, Lgr11, has affected the school teachers in their teaching of reading- and writing and if their work has changed through the years. Using a qualitative study, five preschool-teachers, working in preschool for several years, were interviewed to be heard of their thoughts about this topic. The survey shows that preschool-teachers are more familiar with the curriculum of today, in relation to previous curriculums. Much because of that the new one is more addressed to preschool compared with earlier curriculums but also that the teachers in an easier way can see the pupils? way to knowledge.

The environmental debate is more intensive than ever before and the demands on companies increase. There are a number of methods to make it easier for the companies to fulfil the demands. Life Cycle Assessment (LCA) end ecodesign are some of the methods that can be used. Syntronic AB has the possibility to reduce the products´ environmental impact in the design phase. Therefore it is important for the company to make it possible to visualize the negative environmental impacts a product can cause in an easy way. It is also important to visualize for there clients if any improvement is possible. The purpose of this thesis is to develop a simplified model.
