Agricultural drainage is widely used to manage the amount of water in the ground in order to improve conditions for cultivation. However the effects of drainage companies on water regimes are considerable leading to runoff changes such as altered stream flows, peak flows and water levels. In a greater extent this could imply an increased risk for floods along affected watercourses. This study analyzes the extension of agricultural drainage within the drainage basin of Trosaån in Sweden by ArcGIS mapping. In a statistical analysis, historical variation in streamflow in relation to mean precipitation and mean temperature are investigated for the study area.

The background to this work was to see if there was a connection between large woody debris (LWD) and the presence of brown trout in our Swedish forest streams. Previous researches by Degerman et al. (2004) have shown that there is a strong correlation between the amount of dead wood and the presence of brown trout. The goal was then to find a way to restore, maintain and increase the trout habitats by constructing and adding manmade wooden structures that would mimic natural deadwood and its features in flowing water. The inspiration was partially taken from a water restoration program in the Klamath River of northern California, USA.

One of the most important components of a harvester is the crane. Most harvester cranes are only possible to pivot (or horizontally rotate) at the crane pillar. Cranab in Vindeln, Sweden, has developed a new type of harvester crane which has an extra pivot point on the outer boom. This makes it possible to reach around residual trees, easing thinning work in dense stands. The aim of the study was to analyze if the use of a pivoting outer boom (POB) crane gave an increase in thinning production and if there were any differences in time consumption between the work elements for the POB crane and a conventional crane. A Valmet 911.3 equipped with a POB crane was used in the study.

The emerging Swedish suburbs of the 1960- 1970s started out as a utopian vision: a new city for the modern people. Media presented a different view and emphasized the inhuman livingenvironment and the social problems of the suburbs. Nationwide there have been local attempts to avoid this negative publicity by adjusting identified suburban problems. Due to medial presentation the suburbs are still associated with segregation, criminality and social problems. The presentation of suburbs and immigrants affects not only the process of integration and the general public idea of integration processes, but also the individual perception of themselves and their living.

The stretch from the riparian zone of a major river, through the mouth and upstream in tributaries forms a range of differing habitats. The aim of this study was to investigate the effect of these different habitats on the riparian frog community in primary rain forest in Borneo; i.e. examine whether any gradients could be demonstrated in terms of species composition, diversity and Density of frogs, as well as which environmental characteristics that seem to be of most importance in forming habitats of high conservational value. A major river, Segama, and three of its tributaries were investigated. The surveys were carried out at night by searching for frogs visually and acoustically along the streams, from the shore of the Segama river and 400 metres upstream in the tributaries.

Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between regions. In this study, I investigated if landscape structure (e.g. agricultural dominated landscape opposed to forest dominated landscape), forage availability, population Density and disturbance (e.g. roads and settlements) affect bark-stripping frequency.

The aim of this study is to describe a number of type stands of lodge pole pine in Norrbotten with respect on stem volume and total biomass. Further questions to answer is if there is stand characteristics that make the stands more suitable for pulpwood in early thinning, or if it is better to apply whole tree harvest. The study shall also give an indication if bio energy can be an economical interesting alternative for Sveaskog. Sampled trees represented the variation in the different stands. Five trees were selected from each stand to represent that stand. Stem volume and biomass (kg dry weight (DW) per hectare) for each fraction was calculated.

As the contemporary discourse surrounding urbanism is almost exclusively focusing on aspects of Density and traditional urban qualities, it entrenches notions of what constitutes a proper city and countryside. But beyond this urban-rural dichotomy is another highly contemporary landscape. A territory usually mentioned as sprawl, peri-urban, wasteland, edge city, etc. Although its existence is due to mobilization, telecommunications, globalization and other phenomena of modern life, it is a landscape without an own name or place in public awareness.This thesis provides a case study of how to map and intervene in such a landscape, specifically along the border between Malmö and Burlöv municipalities in southern Sweden. Its structure is composed of a sequence of three parts:1 Spatial Conditions:Divided up in the sections Network, Fringe and Void.

Unmanned aerial vehicles (UAV?s) are nowadays greatly appreciated. The advantage over manned airplanes are great since UAV?s can be much smaller and therefore lighter. The goal of this project is to evaluate the performance of an environmentally friendly UAV using only lithium-ion batteries.

Riskkapitalbranschen är en växande bransch i Sverige och både en viktig finansiär samt kunskapskälla för både nystartade företag och företag med ambition att växa sig stora och internationella. Beroende på vart i livscykeln ett företag befinner sig står de inför olika utmaningar och behöver hjälp med olika saker, en hjälp som riskkapitalbolagen kan bidra med. Studien syftar till att generera kunskap om svenska riskkapitalbolag och bidra med kunskap till den kunskapslucka vi observerat inom ämnet. Studien fokuserar på nätverksstrukturen bland de företag som svenska riskkapitalbolag har valt att investera i samt skillnaden i nätversstrukturen beroende på vart i livscykeln företagen befinner sig.Med en kvantitativ metod har vi, genom att identifiera relationerna mellan de företag som riskkapitalbolagen investerar i, kartlagt nätverken mellan de olika aktörerna. Populationen bestod av svenska riskkapitalbolag och urvalet skedde strategiskt utifrån vad olika källor ansåg vara de två största och mest framgångsrika riskkapitalbolagen i norden.

The aim of this study is to investigate where and why the fitness clubs, Sats and Friskis & Svettis in Stockholms county, choose to locate their facilities in certain places and which their primarily targetgroups are. Furthermore, the aim is to gain knowledge of people?s health status in areas where the facilities are located, in order to see if they are located where exercise is most needed. Interviews were conducted with members of the fitness clubs but also with non members, i.e. people who lived in areas with an absence of fitness facilities.

Leverförfettning är ett metaboliskt tillstånd som är starkt förknippat med den negativa energibalans som kon befinner sig i vid tiden omkring kalvning. Leverförfettning kan i svåra fall påverka leverns funktioner negativt, öka risken för sjukdomar, minska mjölkproduktionen samt orsaka reproduktionsstörningar. Vid negativ energibalans mobiliseras fettsyror från kons fettvävnad för att täcka upp obalansen mellan energintag och energiförbrukning. Fettsyrorna transporteras till levern där de oxideras. Om leverns kapacitet för oxidation av fettsyror överskrids förestras fettsyrorna och triglycerider återbildas som sedan kan transporteras ut från levern som very low Density-lipoproteins (VLDL).

This is a thesis on how to develop and densifythe suburb of Joanneshov south of Stockholm.Based on Stockholm?s urban history,Stockholm master plan in 2010, the currentDensity and sustainability debate, literarystudies, as well as a variety of analysisof the site it all ends up with a proposal onJohanneshov. The goals have been workedout during the work and has resulted inthat we want to extend the inner city streetand linking Johanneshov with surroundingdistricts, but we also want to create a wellused, diverse, urban area where the humanis in focus and a district that is easy to read.Much of the work is devoted to show howStockholm has developed historical and totry to put the future in a context, but also a lotof work has been put in the information andthe analysis of the site chapter. The plan proposalis still considered to be the work focus.Johanneshov is surrounded by Årsta inthe west, Hammarbyhöjden in the east,Enskede in the south and Södermalm inthe north. Gullmarsplan is a typical 40thcentury area with a functionalist structure.Johanneshov is with Gullmarsplan,the Globe an the Slaughterhousearea, an important node for the southernsuburbs as a place for communication,sports, entertainment and shopping.Today Nynäsvägen divides the area intoa western and an eastern part.
