Skogen räknas som en förnybar resurs, men avskogning kan ändå drabba även de tidigare mest skogsbeklädda områdena. Avskogning ger upphov till stora koldioxidutsläpp och förlust av ekosystemtjänster. Med återplantering kan dock ny skog kompensera för tidigare uttag och en god skogsskötsel kan ge en resurs som gynnar både dagens och kommande generationer. Investeringskostnader i skogen kan upplevas som en stor utgift för dagens generation, då avkastningen kan komma att infalla flera generationer senare. I Sverige styrs dock skogsbruket av Skogsvårdslagen (1979:429) och i denna studie riktas uppmärksamheten framförallt på återplanteringsskyldigheten.

This thesis was performed at Indusec ABin Stockholm. Indusec AB is a companythat develops security solutions.Together with the Police of Sweden theyhave gotten the assignment to develop anapplication based on one of theiralready existing product Inferno soundbarrier.

The trigger withwire is the part that will be addressedin this thesis. The application willthen be used as a tool to surprise atarget at various skirmishes.The project consists of three majorphases, pre-study, concept generationand modeling.

Personliga beslut om sparande drivs av många olika motiv, några är, behovet av att bygga upp tillgångar för att finansiera konsumtion under den senare delen av livet, osäkerhet om framtiden och att spara åt nästa generation. Sparandet för konsumtion under pensionsåren är generellt ansett som det viktigaste motivet till att spara. En faktor som ger ett ökat intresse för att studera sparande ärden åldrande befolkningen i de rika delarna av världen. Medelåldern i Europa stiger och befolkningen blir äldre och lever längre.Resultaten visade att inflationen var den variabel som har störst påverkan på sparkvoten. Inte långt efter kom variablerna arbetslöshet, inkomsttillväxt och handelsbalans.

AbstractObjective: To investigate the occurrence of and the risk factors for falls and to  investigate level of fall-related self-efficacy and health-related quality of life in people living in community living, 75 years or older within Uppsala and Västmanlands county. A further aim was to identify predictive risk factors for falls. Design: A cross-section study with a descriptive, comparative and correlative design based on a questionnaire was used. Participants: The participants were recruited from Uppsala and Västmanlands county. A random selection on 525 individuals was done, from a population based sample, in the detailed municipalities.

Digitizing objects and environments from real world has become an important part of creating realistic computer graphics. Through the use of structured lighting and laser time-of-flight measurements the capturing of geometric models is now a common process. The result are visualizations where viewers gain new possibilities for both visual and intellectual experiences. This thesis presents the reconstruction of the Parthenon temple and its environment in Athens, Greece by using a 3D laser-scanning technique. In order to reconstruct a realistic model using 3D scanning techniques there are various phases in which the acquired datasets have to be processed.

The purpose of this BA-thesis is to examine how many girls, boys, women and men who appear in children?s programmes in the years 1978, 1992 and 2007. We have also studied if they are described as typical gender role stereotypes and we have looked at the power conditions between girls and boys, women and men and children and adults. From the results we then examined the changes through out the years. We have made this possible by choosing two days each year when most children were watching the programmes.With the gender role theory we have brought up the important issue of the fact that men appear more frequently in media then women and by doing so the media preserve men as the standard gender.

Youth unemployement in Sweden is at an all-time high, a fifth of all university and college students live in poverty and the number of young on welfare is increasing. This study attempts to answer the question of how youth deprivation has been made possible as a consequence of political action, focusing on youth unemployment. I critically examine the role of the Swedish government, the Swedish Labour Organisation (LO), and the various government departments through text analysis, in order to answer the question of how the current discourse on youth position in the labor market. Because youth unemployment is not an isolated phenomena the analysis covers several policy areas, such as education policy, labor market regulation and housing policy. I use discourse theories drawn from Laclau and Mouffe to expose how language is used as an instrument of political power. I conclude that the current situation is a result of policy choices where the young have fallen behind due to lack of political organization. Their situation is not problematized to the required degree and is often explained on an individual level rather than on a structural level. .

Syftet med denna studie är att undersöka hur olika yrkeskategorier inom äldreomsorgen arbetar med HBTQ-frågor. Studien baseras på kvalitativa intervjuer och inkluderar fem informanter med olika arbetsuppgifter inom äldreomsorgen. Resultaten från intervjuerna har analyserats utifrån olika teman i en intervjuguide, med hjälp av queerteorin. Intervjuernas resultat visar att HBTQ-frågor inte blir belysta som enskilda frågor, men skulle vid behov kunna diskuteras under mångfalds- och jämlikhetsfrågor. Informanterna beskrev vikten av ett gott bemötande, oavsett vilken läggning brukaren hade.

Den dominerande implementationen av POSIX Threads-standarden för Linux har länge varit LinuxThreads. Detta trådbibliotek har på senare tid kritiserats för att leverera bland annat bristfällig effektivitet, skalbarhet och följsamhet till POSIX-standarden. Två nya projekt, Next Generation POSIX Threads (IBM, Intel) och Native POSIX Threads Library (Red Hat) siktar på att erbjuda bättre alternativ till LinuxThreads.Denna undersökning jämför effektiviteten för dessa tre trådbibliotek, i synnerhet i samband med växling, skapande och synkronisering av trådar samt skalbarhet, huvudsakligen genom användandet av ett testprogram från Sun Microsystems.Resultaten visar att NGPT skalar linjärt och är det klart effektivaste trådbiblioteket över 4600 trådar. NPTL är effektivast under 4600 trådar fast dess exponentiella kurva medför sämre resultat vid ett högre antal trådar. LinuxThreads skalade sämst och fick sämst resultat över 1200 trådar och resultaten visade även högst varians.

The objective of this thesis was to present a design proposal on a modular mechanicalstructure for a nanosatellite. The size of the structure should follow the CubeSatstandards. This standard divides satellites in units (U), where 1U is equivalent to acube where sides measure 100 mm. 2U corresponds to the same volume and size as2 assembled 1U structures, and so on. The focus was to develop a structure in theorder of 3U and 6U.At the integration in the satellite launch rocket, there are a couple of differentinterfaces, where the structure is adapted to common ones; P-POD and CSD.

Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

pcSKOG-gård is a computerised manager plan for private forest owners, developed by the pcSKOG AB. The program is based on forest stand data, joined with a map of the forest and GIS-applications. The purpose is to offer a program for private forest owners managing the forest and with the possibility of updating the actual status of the forest. The company pcSKOG AB is the leading producer of programs for forest management and has developed the program since 1997. The program is currently the most common program used by private forest owners in Sweden. The aim of this thesis, leading to MSc in forestry, is to investigate the purpose of the private forest owners when purchasing the pcSKOG-gård. The thesis also studies how private forest owners use the program, what they use it for and how the private forest owners state that the program has achieved to fulfil their expectations. The thesis is also a market research concerning the knowledge and attitudes the private forest owners have about the program and associated services. The study material has been collected during two phases.
