Today 70 percent of the world's sand beaches are under recession due to erosion. The global warming may have the effect upon the sea level increasing and the erosion increasing on the sand beaches. To save these sand beaches, the erosion must be prevented. Coast erosion shelters like gabions and sea walls are functioning extremely well to protect the land behind the sand beach, but due to the wave reflections, created in front of these so called hard erosion shelters, the erosion of the front beach is accelerated. During the last decades, artificial sand supply (beach nourishment) has been the adopted praxis.

The thesis presents an optimally designed kinematic structure for a new 6-DOF haptic devicebased on TAU configuration. The configuration of the TAU-2 proposed by Suleman Khan andKjell Andersson [1] was modified and its mobility was verified by using Grübler criterion tohave a 6 DOF. Analytical kinematic models for the inverse and forward kinematics weredeveloped for the haptic TAU configuration to determine a set of optimal design parameters.Kinematic performance indices such as volume of the workspace, kinematic isotropy and payload index, were defined based on the singular values of the Jacobian matrix. The Jacobianmatrix was scaled to homogenize the physical units. The Jacobian matrix dependent on theposition and orientation of the end-effector gives local isotropy and pay load index, so globaldesign indices were defined, which represent the performance of the mechanism in the wholeworkspace.

Matrix metalloproteinaser (MMPs) är en grupp proteolytiska enzymer som degraderar komponenter i vävnaders extracellulära matrix (ECM). Dessa proteiner spelar en viktig roll i många fysiologiska och patologiska processer. Enzymerna anses vara delaktiga vid olika typer av hjärtsjukdomar där de genom att utöva sin effekt påverkar sammansättningen hos ECM. Aktiviteten hos MMPs hämmas av TIMPs (tissue inhibitors of metalloproteinases) som är enzymernas specifika inhibitorer. Balans mellan nedbrytning och uppbyggnad av ECM är nödvändigt för att bibehålla hjärtvävnadens normala struktur och funktion.

I den här uppsatsen beskrivs en ansats till att med hjälp av statistiska metoder förutse utfallet i förmögenhetsra?ttsliga dispositiva tvistemål. Logistiska- och multilogistiska regressionsmodeller skattades på data för 13299 tvistemål från 5 tingsrätter och användes  till att förutse utfallet för 1522 tvistemål från 3 andra tingsrätter.  Modellerna presterade bättre än slumpen vilket ger stöd för slutsatsen att man kan använda statistiska metoder för att förutse utfallet i denna typ av tvistemål..

Many tropical rain forests has been lost or degraded as a result of human activities and environmental factors. Since the level of biodiversity is high in the tropics, maintaining these areas is of great importance. Forests like these are often assumed to benefit from forest restoration and rehabilitation. The INIKEA project area in Eastern Sabah, Malaysian Borneo, aims to improve biodiversity and/or species richness in the degraded forest through enrichment planting with indigenous species. The objective of this thesis was to evaluate how different treatments (liberation, gap-cluster planting and line planting) affect the biodiversity of natural regeneration in different forest types in the Rain forest Restoration Experiment, located in the INIKEA project area.

The purpose of this thesis is to study how preschool teachers can reach the goal of the swedish educational plan to prevent traditional gender roles for children ages 3-6 through drama in education.This is answered by four hypothesis based on Judith Butler's queer theory, George Herbert Mead's social psychological theory and Gavin Bolton and Dotothy Heathcotes drama pedagogical theories. The hypotheses are tested against four teachers' examples of their work.The hypotheses areHypothesis 1: By using the expert's mantle and active observation in teacher-in-role indrama educational exercises, we can see how the children internalize the heterosexualmatrix and the outline of the internalized other.Hypothesis 2: By using the "mistakes" that occur when children repeat performativeacts that do not fit with the heterosexual matrix, these other possible behaviors can bestrengthenedHypothesis 3: Through drama exercises that are not normative teachers can widen theheterosexual matrixHypothesis 4: Through drama pedagogical methods like teacher-in-role teachers canprovide possibilities of other performative acts and the creation of a more tolerantinternalized other.The analysis show that the respondents work within all these hypotheses in different ways and thathypotheses 2 is the one with the weakest support in the interwievs. The examples are also weakregarding the use of Boltons drama pedagogical methods, but that there are a number of othermethods in use.Some of the conclusions are that more theoretical knowledge in the preschool drama pedagogics tocounteract traditional gender roles and patterns, as well as the drama of educational theory need tobe linked to queer and social psychology research. There is also no monitoring of the long term effects of the work..

This paper appeals to professionals working with green questions. It intends to create a discussion about which plant species that can be established in a fieldlayer of a naturelike planting on fertile agricultural land. To initiate the essay, a studie of which values that can be connected with an establishment of a fieldlayer was performed . A part of Tor Nitzelius Park in Alnarp, a so called naturlike planting on fertile agricultural land, was used as a model for the choice of species. With the aid of soil values, photos and a list of current species, interviews with four ecologists were performed.

Abstract:Perennials in public areas have during the latest decades been more and more popular. This group of plants has become a more accepted komponent when creating pleasant public places, and people begin to see the functional aspects. Perennials do also give a colour- and senceexperience in a more detailed way than can be achieved with only trees and shrubs. One of the ojects of this essay is to give more examples of motives for using perennials in urban areas.Having in mind the increasing use of perennials, you can expect a growing need for better understading of how to create successfull perennial plantings. In spite of the increasing interest it is hard to find any written information in this subject.

The aim of this paper is to analyse how subject, gender and sexuality is constructed in the book Dårfinkar & dönickar (1984), by Ulf Stark. In relation to this I have also analysed how the main character, Simone, develops from being a child into becoming a teenager.Queertheory is the theoretical basis of this paper. Queer theory questions heteronormativity and aims to dissolve conceptions and notions that function in an excluding and limiting way. Queer theory also questions conceptions that seem obvious and/or natural, for example ?woman?/?man? and ?homo-/heterosexuality?.I have chosen to focus the analysis on a number key events in the book and they are categorised according to Tiina Rosenberg`s three dramaturgic concepts: transformation, unveiling and restoration.

Pairs trading is a relatively new trading strategy, the strategy has only been used during a couple of decades. A study made on the American stock market has shown that the strat-egy has generated a positive result. The purpose of this thesis is to investigate if pairs trad-ing has been able to create a positive result on the Swedish stock market during the time period of 1995-2004.The data required for this thesis was collected from Stockholm stock exchange and is ad-justed for splits and issues.The pairs trading strategy involves two stages ? identification of pairs and trading signals. The pairs were identified during a period of 12 months.

The purpose of this study was to identify the way in which history textbooks from the 1980s, 1990s and 2000s used for grades 7-9 depicts World War II from a eurocentric perspective. A qualitative textual analysis was used to achieve the purpose. Three history textbooks from each decade was included in the study, also comparisons have been made to see any changes over time. The study used John M. Hobson matrix describing how the Occident and the Orient are defined from a eurocentric perspective.

Bakgrund: Truppgymnastik är en relativt ung tävlingsgren inom gymnastik med ursprung från de Nordiska länderna. I Sverige är det den mest utövade formen av tävlingsgymnastik med flest rapporterade  skador i nedre extremiteten samt återkommande besvär i ryggen. Tester i syfte att förebygga skador är efterfrågade och få studier har utvärderat tester för idrottande barn och ungdomar.Syftet med studien var att beskriva en grupp unga truppgymnaster utifrån bakgrundsvariabler, och rörelsekontroll med screeningtestet Performance Base Matrix samt att mäta förekomst av muskuloskelettala skador under en period på sju månader. Metod: Nitton unga truppgymnaster (flickor,7-9 år) genomförde screeningtestet Base Matrix i syfte att bedöma deras rörelsekontroll vid låg respektive/ low threshold och hög belastning/ high threshold. Testerna analyserades visuellt och genom videoupptagning. Resultatet av testerna dokumenterades i ett protokoll som bearbetades on-line samt för beräkning av procentuell förekomst av sämre utförd test i form av svaga länkar.

Bakgrund: Evidens finns för att träning inriktad på neuromuskulär kontroll, styrka och medvetenhet kan minska antalet skador i nedre extremitet hos fotbollsspelare. Brister i rörelsekontroll skulle kunna predisponera för smärta, dysfunktion och skador och vara en orsak till skaderecidiv. Syfte: Att studera rörelsekontroll hos unga manliga fotbollsspelare före och efter en träningsintervention på elva veckor med särskilt fokus på ländrygg, bäcken och höftregion. Metod: Tjugo unga elitsatsande fotbollsspelare ingick i studien. Screeninginstrumentet The Matrix Movement and Performance Screen (MPS) användes för att mäta spelarnas rörelsekontroll före och efter en träningsintervention på 11 veckor.
