The effectiveness of Phlebiopsis gigantea to prevent spore infections from Heterobasidionannosum and Heterobasidion parviporum on hybrid larch stumps were investigated in fivestands in southern Sweden. All sites are former forest land and the age of the trees wasbetween 9 and 13 years.The study was implemented in August 2010, a month where spore dispersal should be great.The five sites were located in previously un?thinned monocultures of hybrid larch. The sporeload in the air was studied with the help of spore traps from three different tree species;Norway spruce, Scots pine and hybrid larch. A total of 146 spore traps, evenly distributed inall five sites were analyzed.
Hårdhetsvariation i grundvatten längs Badelundaåsen mellan Leksand och Avesta
Water hardness indicates the concentration of calcium and magnesium ions in water. Water with high concentrations of these ions is described as hard water and water with low concentrations is described as soft water. Water that is too hard or too soft can lead to technical and economical problems. In collaboration with Midvatten AB, groundwater hardness in the Badelunda esker between Leksand and Avesta has been mapped, and an attempt has been made to explain the variations. For this purpose, different GIS programs, such as ArcView, ArcInfo, IDIRISI, and one geochemical modelling program, PHREEQC, has been used.
Produktspårning med RFID : Konceptutveckling och utvärdering
The aim of this thesis was to investigate the possibility of integrating an item tracking systemwith a monitoring system currently under development at Fifth Generation Technologies (P) Ltd.A literature study of RFID technology and the networks ZigBee and MiWi was done. Based onthe literature study a concept for a distributed system was developed.The concept is to have several RFID readers placed in the area where tracking is to be performedand allow them to communicate with each other through wireless communication. The RFIDreaders shall be able to form zones and filter the data that is forwarded from the zones to theservers and thus perform some of the work that the server would normally have to do. Theconcept has been evaluated by prototype development and testing. The prototype uses an ultrahigh frequency RFID reader and a MiWi network.The test indicated some limitations with the selected technologies.

Kaninhållning för sällskapsbruk
The domesticated rabbit stems from the European Wild rabbit and researchers have found that they share most of the characteristics and behaviors of their wild ancestor. They form mating groups in which strong hierarchic orders are formed and they are known for their ability to dig warrens which serve as one of the most important resources for this species. Although research has been performed to increase the welfare of rabbits kept in laboratory settings little is known about the housing, behavior and welfare of the pet rabbit. Among the research that has been performed within the area results have shown that the animals are kept in small solitary cages and that although many rabbits are purchased mainly for the children many animals cannot be handled by children due to display of aggression. Another conclusion drawn is that the animals are kept in ways that differs greatly from their natural environment.

Näsbyholm - parken och de närmaste omgivningarna ur ett historiskt och nutida perspektiv
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. The islet was at this time completely surrounded by water and there was a drawbridge over the narrow waterline.
The owners are liable since the late 1200s.

Innehållet i Magasinet och Ess i svenska utifrån styrdokument och betygskriterier
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.
Etablering och Integrering - en undersökning av samarbetet mellan Arbetsförmedlingen och flyktingmottagningen i en mellanstor kommun i södra Sverige

Tillgängligt landskap : spänger i naturmark
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.
? Det handlade egentligen om att någon inte tog mina problem på allvar?? : En studie om ungdomars psykosociala hälsa och skolsituation
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.
Ett vårdinformationssystem i vårdens frontlinje : En fallstudie om Cambio Cosmic på en vårdcentral i Landstinget Kronoberg
In healthcare there is a rapid development towards introducing and implementing a wide range of information technology (IT) to aim for higher quality and more effective care. A common health information system (Cambio Cosmic) has been implemented in Landstinget Kronoberg. Clinical microsystems are the frontline units where staff and pa-tient meet. When the conditions in the microsystems are changed, it is interesting to de-scribe and analyse the consequences.The purpose of this study is to describe how health care staff uses a health information sys-tem and how they experience its functionality in their patient work. Initially, a literature re-view about the use of health information system was undertaken, followed by a qualitative case study based on interviews about how healthcare staff describes their reality.
