Markavvattningsföretagens geografi och konsekvenser i Trosaåns avrinningsområde

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.

Organisationskultur ur två perspektiv : En jämförande studie av två etnografier ifrån socialantropologi och organisationsteori

This study aims to compare two ethnographies of organizational culture ? one from the discipline of Social Anthropology and one from the discipline of Organizational Studies ? considering their purpose, their method, and their concept of culture. Despite big similarities, or perhaps thanks to the similarities, some fundamental differences are made visible. The discipline of Organizational Studies has, compared to that of Social Anthropology, regarding the research method being used, less focus on, and less participation in, the informal social life of the organizational culture of the study. Regarding the concept of culture the Organizational Studies consider culture containing more of unity, stability and clear boundaries, compared to Social Anthropology.

Maximerande av ekosystemtj?nster i urbana kulturmilj?er: En fallstudie om tr?dval i Pommerska tomten i Mariestad

The purpose of this work has been to explore what ecosystem services a small green area in an urban environment can offer and whether specific trees can be used to maximize regulatory ecosystem services in a cultural-historical environment. Additionally, it investigates whether there is any difference in ecosystem services depending on whether these trees, or trees that better fit into the cultural-historical environment, are used. Through simulations and comparisons with existing trees in Pommerska tomten, Mariestad, Sweden, a pocket park within a national interest area, different hypothetical tree planting options are analyzed and evaluated. To measure ecosystem services, the website My-Tree, developed by the US equivalent of the Department of Agriculture, was used. By inputting data about the tree, such as location, species, vitality, stem diameter, and solar exposure, My-Tree calculates some of the ecosystem services the tree provides.

Alnarps rehabiliteringsskog : ett gestalningsförslag

The understanding of the role of nature for rehabilitation of both physical and psychological afflictions has greatly increased in the last few years. There?s a lot of science that describes the healing effects of nature. The rehabilitation garden in Alnarp has contributed with very positive results from the treatments of patients with burnout syndrome. In the first stages of rehabilitation, the need for calm is very important and a demand-less and stress-free environment is of essence.

Vem håller i taktpinnen i krisberedskapsarbetet? - En studie av risk- och sårbarhetsanalyserna i länsstyrelserna

Crisis management planning is a relatively new policy area in the European countries. It has materialized since the fall of the iron curtain and because of the increased interest to prevent wide-ranging national emergencies. In Sweden, the county administrative board has a key obligation to perform risk analysis guidelines. This assessment involves identifying crisis, planning response to the crisis and, if necessary, confronting and resolving the crisis in the geographic area of the region. The purpose of my thesis is to examine if there are any differences in crisis management planning between the county administrative boards? risk analysis guidelines.

PPM - Passivt Placerande för Många : En analytisk studie av premiepensionsspararnas avsaknad av strategier för fondval

Introduction: In 1998, the pension system was changed and the so called PPM system was introduced. The PPM system is partly fund-based, partly distribution-based. There are approximately 700 different investment funds to choose between, at a maximum five for each individual. For persons who are not familiar with the financial market, the choice might be difficult. The lions? part of the investors do not seem to have an active strategy.

Landsbyggdens egnahem i Malmöhus Län 1905-1040. En studie av markförsäljningen till fastigheter som beviljades egnahemslån

During the period 1905 to 1940 it was possible to get a loan from the state to buy land and build a small farm or a house in rural areas. This loan act and its effects have been studied earlier in different ways, but never as a total study for a geographic region. The region Malmöhus Län has been chosen. The purpose of this paper is to study in which parts of the area loans were taken and who sold the land that was used for these purposes. Earlier studies have looked at a larger geographical area for some specific years.

Diskussion om röjningsrösen : med teorier om gravrösen i fossil åkermark och skärvstenshögar

This paper aims to investigate the connection between clearance cairns and burial cairns. From this point of view I try to answer the questions why they are built in the same area and why these two different types of cairns are so similary constructed. Further I consider different theories about mounds of fire-cracked stones..

Huntingtons sjukdom och dess cellulära mekanismer

De gamla ängs- och betesmarkerna hör till Sveriges artrikaste biotoper, ofta med en mycket hög arttäthet inom både flora och fauna. Ängs- och betesmarker har minskat kraftigt under det senaste århundradet vilket har lett till en utarmning av den biologiska mångfalden. Denna undersökning sker i samarbete med Täby kommun och syftet är att undersöka 10 olika ängs- och betesmarker för att få en uppdaterad bild av hävdtillståndet och vilka åtgärder som är mest lämpliga att sätta in.Detta arbete avser att fungera som en grund där framtida undersökningars resultat kan jämföras med för att se vilket resultat de insatta åtgärderna gett. Metoderna som använts är en allmän artinventering, art/area analys och successionskategorier utarbetade av Urban Ekstam samt studier av indikatorarter och lokalernas allmänna utseende exempelvis om mycket gammalt gräs finns i lokalen. Art/area- kurvorna studeras vilka genom sin lutnig och form visar vilken arttäthet som råder i det studerade växtsamhället.Flera av de undersökta lokalerna visar tecken på igenväxning och domineras främst av konkurrenskraftiga kvävegynnade arter. Dock finns ofta mindre bestånd kvar av hävdgynnad flora vilka skulle få en chans till expansion om en intensivare hävd sätts in.

LiDAR-bildanalys av flutings i södra Norrbotten : Kartering och datering av avvikande isrörelseriktningar

The aim of this study was to map and date glacial flutings with ice flows deviating from the predominating northwesterly ice flow direction in the southern part of Norrbotten County in northern Sweden, and also to investigate if parts of the glacial landscape are older than previously thought. The traditional view is that most landforms in the area were formed during the late Weichselian (W3). Analysis of the new high resolution elevation model (2 m grid) derived from laser scanning was performed after treating the data with a hillshade tool in ArcMap to reveal terrain features such as flutings. The analysis resulted in a map showing four main groups of deviating ice flows (N-S, NO-SV, SO-NV and S-N) and several westerly ice flows. The majority of flutings with deviating ice flows were found in low terrain.

Val av område och områdesskydd för Natura 2000 med skogshabitat : En jämförande studie av fyra län i Sverige

The Natura 2000 Network is one of the European Unions many tools concerning nature conservation, and is without comparison the premier contribution when it comes to halting the loss of biodiversity. This essay is a case study on how the regional work with the Natura 2000-network has been carried out in four different counties. These counties are Södermanland, Västernorrland, Jämtland and Örebro. They have been compared based on the theoretical concept of sustainable development. This essay describes how the officials in the County Administrations view the regional implementation of Natura 2000 when it comes to the selection of Natura 2000-sites with forest habitats and the creation of an additional protective measure.

FORSKNINGSPOLITISK INTEGRATION GENOM INNOVATION

Research and innovation are areas that have been evolving quickly during recent years. However, it has been difficult for individual countries to make progress on their own. To solve this problem the European union have launched the most expensive research and innovation program to this day. By combining national governments throughout Europe, the EU wants to create cutting edge technology that will strenghten the region and make the union able to compete on a worldwide stage. However, trying to combine national governments has not been easy, the programs struggle with byrocracy and member states of the European union are tentative about supranational institutions. By engaging in the program national governments have been afraid of how this will affect their sovereignty.

Skötsel av tätortsnära skogliga rekreationsområden : besökares upplevelser i norra och södra Sverige

The main purpose of this M. Sc. thesis is to increase the knowledge about managing urban forestry for recreational use. The analysis is focusing on differences between visitors? experiences in the north and south of Sweden, represented by Nydalasjön and by Härlanda tjärn.

Inventering av flodpärlmussla i Fylleån norr om Gyltigesjön

Freshwater environments are threatened worldwide, of which many of the species associatedwith freshwater. In 2014, 243 freshwater mussels were on the international Red List. One ofthem is the freshwater pearl mussel, Margaritifera margaritifera, which because of itscomplex life cycle can be counted as an indicator of whether a stream is worth protecting. It's since the early 1900's in decline throughout their range. Sweden is counted as a core area which is why we have not only a national but an international responsibility to conserve the species.

Energieffektivisering av befintlig bebyggelse med exempel från Göteborgsområdet

This thesis concerns to investigate renovations of existing buildings aiming at enabling energy efficiency, from a conservation and restoration perspective. This includes performing case studies of three projects in the Gothenburg area where renovations has been done and an analysis of directives raised by the EU and later implemented by the Swedish National Board of Housing, Building and Planning, Boverket. In addition to these, regulations enforced by the Swedish law, related to the topic, have been considered.The investigated projects in this case were the housing cooperative Välten in Brämaregården, the Solar Buildings in Järnbrott and Gårdsten as well as Katjas Gata 119 at Backa Röd. In order to measure and compare the results of these projects a comparison between the pre- and post-restoration energy consumption have been performed. To capture additional perspectives the grading system Operation Kungsörn has been applied.Regarding the comparison of energy consumption the renovation of Katjas Gata 119 was found preferable but showed in my view lacking attention to the cultural heritage of the area.
