BIOGAS POTENTIAL IN GRASSES FROM WETLANDSMarvin MartinsThe purpose of this study has been to survey wetlands that are suitable for mowing and to analyze the biogas potential in the harvested grasses. A preformed investigation showed that there are suitable wetlands, which can be harvestable, namely those mowed formerly in traditional haymaking. The practice of traditional haymaking is dying out in Sweden today but there are several good reasons why it should to be reconsidered. Nature- and cultural values are obvious, also the unutilized energy in the grass.The suitable types of wetland that were specifically studied were the productive wetlands; meadow marshes and wet meadows. These wetlands are represented in the Swedish meadow- and pasture inventory database; (TUVA) and the Swedish national wetland inventory (VMI).

I Sverige finns cirka 60 tjejjourer som ideellt arbetar för att stötta och stärka unga kvinnor vars psykiska ohälsa fortsätter att öka. Statistiskt sett så finns klara samband mellan den psykiska ohälsan bland flickor i Sverige och orsak till varför de stödsökande hör av sig till tjejjourerna och andra ideella organisationer. Syftet med studien var att beskriva vad jourerna gör för att förbättra den psykiska ohälsan bland flickor samt att beskriva faktorer som påverkar det ideella arbetet på tjejjourerna enligt de aktiva medlemmarna. En kvalitativ intervjustudie användes som metod. Sju intervjuer genomfördes på aktiva medlemmar på olika tjejjourer och analyserades med hjälp av en innehållsanalys.

SCA Skog has taken the initiative to this Master?s thesis. Today SCA Skog has a great need to update their informtion on young forest stands across large areas. Traditional field inventory methods for updating stand databases are expensive and time consuming. However, the inventory could be made more efficient if stand boundaries and stand characteristics are derived from aerial photographs.

This report describes an analysis of WebGL together with JavaScript with the aim to examine its limitations, strengths and weaknesses. This analysis was performed by building a 2D game engine containing some dynamic elements such as water, smoke, fire, light, and more. Different algorithms have been tested and analyzed to provide a clearer picture of how these work together. The report will go through the most basic functions of the game engine and describe briefly how these work.The result shows that JavaScript with WebGL can be considered to be a potent toolsets, despite the difficulties caused by JavaScript.In summary, similar projects can be recommended as Javascript and WebGL proved both fun and incredibly rewarding to work with..

This project is an attempt at creating a bag that is both functionaland has an interesting and relevant visual appearance. I have found that a bag that is functional usually have adapted certain aesthetics which are appealing only to a very limited target group. At the same time many bags that are more focused on style can be downright disabling to the carrier. I wanted to create a functional bag, and to explore new functions doing this, while working with aesthetics that stayed relevant and interesting to my target group. The bag was designed for the company Åhléns and their label WERA Stockholm, and theircustomers was the target group.

Studier har visat att frivilligt barnlösa individer stereotypt har betraktats vara olyckliga och otillfredsställda, något som inte har fått vetenskapligt stöd. Syftet med den här tvärsnittsstudien var att undersöka om det föreligger några skillnader i livskvalitet och livstillfredsställelse mellan frivilligt barnlösa personer och föräldrar i den svenska populationen. Forskningsfrågan undersöktes med en enkät som bestod av självskattningsskalorna QOLI (Quality Of Life Inventory) och SWLS (Satisfaction With Life Scale). 130 deltagare genomförde studien varav 54 är frivilligt barnlösa individer och 76 är föräldrar. Studien visade att det inte finns några signifikanta skillnader mellan grupperna med avseende på livskvalitet och livstillfredsställelse.

Sweden has today the highest moose (Alces alces) population in the world. The population has been very high since the late seventies and in the beginning of the eighties there was a big ?moose explosion?. The main food source for moose during the winter is young pine (Pinus sylvestris) and birch (Betula spp.). The high moose population has therefore lead to high damage on pine forests over big areas.

An analysis of Zolas Nana focusing on male desire. Through a study of the narrtive structure and the polemic relation between the concepts of ?Nature? and ?Culture? it is shown that opposing ideologies are imbedded in the text. Nana is a symbolic character, in large, a myth created by male desire that eventually becomes a manifestation of that desire. At the same time, however, the character Nana evolves from being a mirrored image of male desire into a more stable and real individual and this process is also an answer to when and why she dies,underlining the fact that she initially was a creation emanating from male desire and in losing those symbolic functions she loses her function in the novel..

The electronic music studio ?Elektronmusikstudion? (EMS) inStockholm was initiated in 1963. It has had several different managers throughout the years. EMS soon became a rather costly project. Furthermore there have been several conflicts among staff and users wich has contributed to EMS fairly turbulent history.

Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

During adolescence the teenager tries to become an independent individual, something that for many individuals can be experienced as"a hard time". In early childhood the individual was closely connected to the parents, but during adolescence friends and new contacts become more important. Studies in developmental psychology have most often adopted a parent-perspective, which is why a child-perspective is required. The aim of this study is therefore to measure the teenager's relationship with parents and friends and to look for possible correlations between these. As a means of measuring quality in the relationships, the IPPA, the Inventory of Parent and Peer Attachment, was used.

The purpose of this study was to examine whether an inventory of the vegetation overgrowth could be used to indicate a locally nutritional impact. The study was conducted at Märstaån where the water runs through a number of agricultural lands that could lead to an increased amount of diffuse emissions of nutrients. The vegetation overgrowth in the water was also studied in relation to shade, meandering and water flow effects on the vegetation. With this method, no definitive conclusions could be drawn.Where the water was shaded, no vegetation overgrowth could be found. Therefor trees should be planted to prevent any future overgrowths.

There are several thousands shallow bays along the Swedish east coast. Most of them are disturbed by different human activities, and undisturbed bays can be considered as quite unique. In the sheltered shallow bays water warms up more rapidly than adjacent water favoring the growth of vegetation, which in turns is beneficial to spring spawning fish species like perch and pike. It is nowadays more common that coastal habitats are inventoried to facilitate future preservation and planning. The aim of this study was to investigate the shallow bay Utanåfladen (59° 53`31.38 N 19°00`44.90 E) in the north Stockholm archipelago and evaluate its habitat value.
