Wetlands play an important role in the ecosystem. They reduce the impact of flow flux in the drainage area, acts as upholder of biodiversity, as an esthetic and recreational component in the landscape and they have the ability to reduce nutrients such as nitrogen, and help preventing eutrophication in costal areas.The number of wetlands in Scania have, due to the intensified agriculture been reduced to maximize the area suitable for crops.However since the mid 80th the consequences of this has been acknowledged, and many wetlands have been restored.This master?s thesis aim to see what impact this development have had on wetlands in Scania over the last 60 years. And also look at some of those factors important for the efficiency of nitrogen removal in wetlands. During the process a detailed manual for inventories of this sort was created.The material used to execute the inventory of wetlands where aerial photographs over Scania from the 1940th, 1980th and 2000.

Adolescence is a turbulent time in life and gives rise to new information needs for young people. Information needs related to school subjects have been relatively well researched but few studies have focused on information needs and use related to life concerns. The purpose of this Master's thesis is to examine the information needs of a number of teenage girls in relation to their life concerns and how they meet these needs. The sample consists of twenty-one girls aged thirteen and fourteen. The research is based on literature studies and qualitative interviews combined with a questionnaire.

The number of ideas at innovative companies usually exceeds the amount of available human ormaterial recourses, this include ideas for development of new products. Since they are not able to doeverything they want to do they have to choose between ideas to develop new products. This includesthe decision on when to start, stop or kill a project as well as the thought process of prioritizing betweenongoing and potential projects.Project Portfolio Management (PPM) is an organizational process, with the purpose of systematicallyorganizing and running the activities that aim to evaluate, select and prioritize ideas and projects fordeveloping new products. PPM include four major goals to be fulfilled; Maximizing Value of thePortfolio, Achieving a Balanced Portfolio, Achieving a Strategic Alignment and Running the RightNumber of Projects.The purpose of the thesis was to develop a more visual and formal PPM process for the early stages inproduct development in one department at St Jude Medical AB, Sweden.The thesis was conducted by following a methodology known as Process Modules. The methodology isan approach for developing a PPM process that fits a specific company.

The objective of this study was to contribute with suggestions of nature preservation managements of selected forest objects of high nature values managed by the Swedish state-owned forest company Sveaskog. Many forests with high natural potential are relatively rare today due to modern forestry, where wood production is the main purpose. Sveaskog?s policy is to consider and to priority nature conservation on valuable objects. This assessment includes objects that in the future may develop into nature reserves.

The quality of bread wheat is a large subject to study. The quality rests on two legs. The first one is the inheritance of specific characters, which can be influenced through plant breeding and type of cultivar. The other one is the environmental influences, such as crop rotation, nutrition, harvest and storage. The latter factors are possibly to affect through cultivation practices, while other factors are not possible to influence on for the grower, such as seasonal changes of weather and the soil content.

Industrial buildings are increasing all over Sweden. Farmers are building new modern facilities and the government chooses to build new halls to invest i youth sports. Glulam is the most common framework but there are limitations because of the transport. Therefore, there is a need to develop new solutions to increase the use of glulam.The maximum torque in the eaves was found in the frame with a roof pitch of 18 degrees and a wingspan of 25 meters. Using hand calculations according to Eurocode and comparison with the computer software StatCon, the maximum torque, shear force and utilization rate is calculated.

Today there are a number of different financing options but few of them are suitable for start-up companies. Business angels are in that case an exception and a suitable investor in these companies. Business angels are individuals who invest in young companies and differ from other financiers in the sense that the collaboration with the company is closer. Business angels are although few in numbers while the young companies often tend to be in most need of funding and has the greatest potential to grow.The purpose of this study is to gain a deeper understanding of the cooperation between entrepreneurs and business angels and to identify which effects the financial gap have on these financial associations.Business angels and entrepreneurs collaboration are hard to interpret and therefore demanded a deeper examination. We thus used a qualitative method consisting of six different interviews in three different cases.The study shows that established collaborations between entrepreneurs and business angel?s seem to be affected by the financial gap to a great extent, which has been expressed in negative consequences.

AbstractConsider a ?uid being heated from below. The heating leads to an upward convectiveforce that is counteracted by the viscous forces of the ?uid. If the convectiveforce is large enough in comparison to the viscous forces the ?uid will be put in anunstable state.

This thesis studies settlement continuity on Gotland between approximately AD 200 and AD 1700. The method used is to calculate correlation between the geographical distribution of all known Iron Age stone-wall-houses (on Gotland known as "kämpagravar") and all farms included in the detailed taxation maps from approximately 1700. The number of remaining house foundations is between 1800 and 1900. A model to estimate the number of removed foundations is presented. It is based on the assumption that the settlement density was proportional to land use around 1700, and that the rate of removal is related to the current land use.

There is a need for productivities data and data for different types of machines for comminution of logging residues. The lack of data and studies on GROT comminution makes it difficult to evaluate different chains for handling of residue fuels and make system analyses.Four types of machines with three different working principles were compared at six studies during winter conditions. Three to eleven trials during 9.5 to 30.7 minutes were made on each machine. Samples from the produced material at each study were sieved to determine the size distribution of the comminuted material. Samples were also taken from the studies for determination of moisture content.

In writing this study, I wanted to examine which principles of organization that are possible for Swedish public libraries to use, and what these principles mean for the libraries customerorientation. This is done by examining a number of written sources, as well as studying the organization of six public libraries. I found several possible principles, but a number of principles have been more commonly used than others. Historically most public libraries were organized according to the functions needed to be carried out within the organization, but today it is much more common to use subject-based organizations, with some examples of organizing according to user-groups and needs. I have also encountered the possibility of organizing according to the sources that are to be handled, or the way in which these sources are used by the customers.

The purpose of this paper is to create an understanding of the negotiation process behind the decision of who will stay at home with a sick child and to develop the knowledge of the mechanisms considered to affect the negotiation process, in particular, the mechanisms likely to contribute to an uneven use of care leave. In the study six interviews were conducted with three sets of parents. These interviews were then analysed with Janet Finch?s (1989) definition of negotiation of family responsibilities. The study finds that the negotiation on care leave is a result of the negotiation of the shared view of reality.

Inspired by the current debate over the effectiveness of Public Relations (PR), the authors of the following thesis have sought to analyze how PR and advertising differ in terms of how they affect consumers. The subject of the thesis was chosen due to the lacking knowledge of how PR shapes consumer attitudes and intentions. The authors wish to upset the institutionalized myths which dominate in the PR-business. One example of such a myth is that the effectiveness of PR can be measured by the number of press releases an activity produces and that PR?s superiority over advertising is due to its higher trustworthiness.

Livestock animals affect their environment in a number of different ways, mostly through grazing and trampling. This study focused on the effects of Gotland pony grazing on forest structure and diversity, and the impact on ground cover. To compare the fenced and grazed area with a reference area outside the enclosure a number of transects were used. The study showed that there was no significant difference in height structure and diversity between the compared sites; however, there were a significantly higher proportion of damaged trees inside the enclosure. The ground cover variables showed a higher amount of bare soil, plant litter and wood-rush (Luzula sp.) inside the enclosure whilst grass was more frequent in the reference area.

This essay investigates how the chapters of the interwar and the Second World War have changed in the high school history textbooks during the period from 1944 to 2008. In the study eleven history textbooks have been studied, most quantitatively but also qualitatively. For example the number of pages and rows devoted to different subjects and countries are compared in the books over time. The result of the study shows that there are some big changes over time but in most sections there are also big differences between the books, which make it harder to draw general conclusions. There are a lot more names, pictures and dates in the newer books compared to the older ones, although the number of different names is about the same in all the books.
