The freshwater pearl mussel (Margaritifera margaritifera) is threatened throughout its range. There has been a substantial decline of the species and one major reason is habitat degradation. We investigated how the substrate composition of the bottom floor affects the regeneration of the mussel by analyzing data from the Västerbotten County Board?s inventory of the freshwater pearl mussel. The results implied that fine material such as fine sediment and sand might be detrimental to regeneration whereas gravel and boulders and in particular stone seem to be beneficial.

I have in my thesis produced a start of a multiplayer, voxel, strategy sandbox game withadvanced AI. The world is made out of voxels in the form of blocks that both the players andother units can affect and change. In a world where every block follows the laws of physicsfor both fluids and physics. The game is designed for several players that fights for controllover land and resources..

Many companies are presently investing in different types of environmental strategies, and it is varying to what level they channel their resources to environmental efforts. It is also diverging to what extent organizations effort to profile themselves as environmentally conscious. This can be due to difficulties in reaching out to customers and to finding the most efficient method of green marketing communication. The aim of this study is to analyse how an insurance company more actively can communicate environmental matters foremost in their contact with customers. One can in different mediums daily follow debates and discussions concerning the environment. Many insurance companies have also identified their role in performing green work.

The specific task of this thesis is to illustrate the complexity of a cooperation between civilian and military entities by examining Provincial Reconstruction Teams (PRTs) and their role as an actor among others in the field in a war-torn Afghanistan.By using counterinsurgency strategy as an analytical framework it has been possible to examine the civilian and military contexts closer. Underlying structures concerning the norms and interpretation of reality of the PRTs has been partly revealed. Studies of the PRTs as one significant bearers of "the comprehensive approach", which includes a holistic approach regarding the use of civilian and military capabilities, new conclusions can be drawn on whether a general civil-military approach can be a part of the solution for current and future conflicts. Based on the counterinsurgency strategy, the author has identified three themes as bearing and thus appears through the thesis as a foundation. These are Coordination, Development and Security.

I en allt mer föränderlig omgivning utgör innovation ett nödvändigt redskap. Syftet med denna studie är att undersöka om arbetskrav och arbetskontroll samt interaktionen dem emellan har en betydelse för ettgruppklimat som främjar innovation. Arbetskrav och arbetskontroll definieras i denna studie utifrån Karaseks teori om krav- och kontrollmodellen. Innovation definieras utifrån Wests teori om de fyra gruppklimatfaktorerna som främjar innovation. Resultatet baseras på en enkätundersökning med 83 respondenter fördelade på 20 arbetsgrupper inom den privata sektorn.

Durban, South Africa?s third-largest city is a socially segregated post apartheid society, struggling with high unemployment and AIDS. The city becomes even more complex with a changing climate, creating an influx of people to the city, putting scarce resources under further stress. Warwick Junction, an important transport hub in the centre of Durban, holds a large site of informal trading alongside the formal markets. This informal sector generates large financial flows and provides for a rapidly growing population. The aim of this thesis is to develop an approach that is realistic and relevant to planning and design of an urban context in South Africa.

Investment in hedge funds is a relatively new phenomenon for investors compared with other forms of savings. In recent years, the interest has increased among investors in investing their money in hedge funds, given the protection against declines in the market they are aiming for. Their main purpose is to generate a high return at a low risk regardless of market trends. This they can achieve by having fewer restrictions that offer more flexible investment strategies and freer investment opportunities.The purpose of this paper is to identify how the selected hedge fund strategies have performed during the recent economic downturn. We also want to clarify the claim that hedge funds exhibit a positive absolute return regardless of what the market is performing.In order to answer the purpose of the essay and its problems, we have used a quantitative method with a deductive approach in the processing of data.

Since the end of the eighteenth century forest damage caused by the pathogen Gremmeniella abietina has been observed and documented. During the latest epidemic in Sweden more than 480 000 hectares forest land have been injured and this has lead to considerable economic losses. For the pathogen to succeed with infection, spore dispersal and colonization the right environmental conditions is required. The aim of this paper is to describe the diseased stands using site and stand characteristics and to evaluate the effect of these variables on the disease incidence. Further, the thinning performed during the time for spore dispersal and its relationship to injured stands is examined.

The city?s public environments are meant to be perceived as safe and inviting areas to visit any time of the day. In recent decades the number of vandalism complaints has doubled and graffiti has become so common that it received a separate category in the crime statistics. With this type of impacts in the public environments the experience are precarious and a boring sight. It?s difficult to put a price tag on these types of crimes, the number of unreported cases suspected to be large.

Bakgrund: Den logistiska kedjan från producent till konsument blir alltmer komplex på grund av att ett ständigt ökande antal artiklar tillverkas utifrån kundens behov och önskemål. För att kunna tillgodose dessa behov och önskemål har företag historiskt sett haft stora lager. VMI tar problemet med att hantera och utveckla effektiva lager till en ny nivå. Att arbeta med VMI innebär stora fördelar för många olika företag när det gäller informationsspridning, partnerskap och lagerföring. Trots de omfattande fördelar som beskrivs i de flesta teorier om VMI finns det en del framförd kritik.

AimThe aim of this study was to investigate if the Swedish elite soccer teams, both males and females, have preventive strategies to reduce the risk of muscular injuries in the posterior thigh.MethodA survey was created and sent by mail to all (n=28) Swedish elite soccer teams in allsvenskan (both males and females) to be answered by the head of physical exercise within each team. A pilot study regarding the survey was performed by two soccer coaches on elite level and was revised afterwards. The survey was conducted between May through July 2013. In total, 18 soccer teams participated in this survey.Results10 soccer teams did not respond to the survey, which resulted in a drop out of 36%. Preventive strategies to reduce the risk of muscular injuries in the posterior thigh existed in 16 of the teams.

Today green tree retention, together with leaving dead wood, is a common practice with the aim to reduce negative impacts on biodiversity and environment due to clear-felling. To better understand whether this conservation practice also makes a long-term difference, it is important to know what happens to these trees after harvest. Few studies have made an assessment of what happens to retention trees over a longer time period. In this study I inventoried retention trees that were left at clear-cuts six, twelve and eighteen years ago. I carried out a re-inventory of 57 retention patches (divided into free-standing tree groups, small swamp forests and edge zones) and free standing dead trees, spread over 25 previous clear-cuts in central Sweden.

There are plenty of exciting changes being developed in Tre Högar´s Park, which is located in the district of Linero, eastern Lund. A project group representing Linero If, Lugi Tennis and Linero/Östra Torn Health centre, has been created and is responsible for managing a development project of the Park. Their main focus is to create sports, exercise, health-promotion, health-care, recreation and rehabilitation facilities. They view the park area as having great potential and will transform it into a purpose built park for Health and Exercise. There are various authorities involved with and engaged in the scheme; aside from the project group, the municipality of Lund, The sport association of the handicapped and local schools are being consulted.
