Förutsättningar för drift och underhåll av det statliga vägnätet : - En fallstudie om entreprenadkontrakts utformning i driftområdena Åsele och Jokkmokk
This study aims to analyze the risks with building new households between railroads and shore, the focus of the study lays on Öbacka strand in Umeå municipality. The study also investigate if a land use conflict has taken place and how it was handled.The paper is based on different documents that was central for the work of planning the households and some interviews with operators that was highly involved with the planning of the area.The results shows that there is several risks with establishing new household between railroads and shores. Mainly because of the exposure of noise from the railways, though the risk for impact on the living environment for animals were low in this case there is a generally risk that it could get negative effects. It also a very important that the availability to the shore is secured. Planning in this type of area involves a great number of operators can easily cause a conflict due to the different perspectives on how the land should be used in the future, and also because of protecting different interests.
XRF-analys av förorenad mark : undersökning av felkällor och lämplig provbearbetning
X-ray fluorescence (XRF) detection of heavy metals is a cost- and time-effective method for investigation of polluted areas. Compared to laboratory analysis, XRF analysis is limited by high detection limits and uncertainties in some situations. Preparation of samples is known to affect the results of measurements.The purpose of this thesis is to bring a deeper understanding of how different factors affect the results of XRF-analysis. A large number of measurements have been made with the instruments Niton XLt 700 and Niton Xli 700. Results from measurements of lead, zinc and copper have been analysed.This study has shown that a greater moisture content will give a lower measured concentration for the same sample.
Stolthet och fördomar: upplevelser av hur det är att vara ung i Herrgården
The purpose of this essay was to investigate the experience of being young and living in Herrgården in Rosengård, Malmö, from the aspects of six adolescents, two police officers, one social worker and one youth leader; and also what the cause is according to them, of disturbances arousing like those in the spring of 2007. At this moment there were antagonisms between adolescents and policemen. The research was performed with a qualitative method based on partly structured interviews. Four kinds of main themes were notable from the interview results. Those were: Growing up in Herrgården, Other peoples' view of Herrgården, Identity and Causes of the disturbances.
Riskbedömning av miljö- och hälsoeffekter efter järnhanteringen i Strömsbergs bruk
Risk assessment of effects on the environment and health outcome caused by the iron industryLina LöfqvistIn Sweden you can find lots of contaminated areas, which can create problems for both humans and nature. To reduce the long-term contamination grades, Naturvårdsverket have created a report with regard to the contaminated sites. This builds on the ?Method for Inventories of Contaminated Sites? which is abbreviated MIFO. The aim of MIFO is to achieve better environmental planning in Sweden.
Effekt av olika kvävegödselmedel på utvecklingen av klumprotsjuka i salladskål (Brassica rapa ssp. pekinensis)
The price trend on rapeseed the latest years has led to an increasing interest to grow the crop among many farmers in Sweden. The price trend has resulted in more than a doubling of the oilseed area since the early 2000s. For many farmers it is an advantage to increase cultivation of rapeseed because of the high proportion of cereals in the crop rotation on many farms, but it is not just benefits. The risk of the fields being infected by clubroot increases within frequent rapeseed cultivation and it often leads to subtantial economic losses. Clubroot is caused by Plasmodiophora brassicae that is a soilborne pathogen in genus Protozoa and its resting spores can be found in the soil for up to 18 years.
Socknen - den plats vi är : En studie om platsuppfattning i Ydre kommun
The term socken ? comparable to the English term parish ? refers to a historical geographical entity found in rural areas of Scandinavia. This entity presents a multi-layered understanding of the local rural area and is in this essay conceptualized as a place. The concept of place is central to geographic work but it is also a contested term ? discourses within the field of geography present different perspectives on place as a geographical concept and our understanding of it.The history of parishes goes centuries back.
Spårtrafik i norra Stockholmsregionen
Northeast Stockholm is a region developing fast. There is already a great need for new transport solutions for the people commuting to the city, since long queues slow down car traffic and the local railway, Roslagsbanan, needs to be upgraded to attract more travelers. The competitive advantage of rail?traffic over the car when it comes to greenhouse gases and air pollutants is another reason to develop Roslagsbanan.This report investigates the differences between car and train to create a basis for a proposed expansion of Roslagsbanan. Once the proposal is presented, costs, emissions reductions and public benefits are analyzed.

This paper is divided into different sections, containing the patents of the automation of different steps in the process.
Implementering av Patientsimulator för Anestesimaskiner
In order to facilitate testing of anesthesia machines a patient simulator has been required by Maquet Critical Care AB. A patient simulator has been developed to reduce expensive and time consuming animal experiments and temporary lab arrangements. The patient simulator has been developed and designed to simulate human lungs with regards to anesthetic uptake, production of carbon dioxide and heating and moisturizing exhaled air.The system comprises a container and a test lung to simulate the volume and the dynamic of the human lung. The simulation of uptake of anesthetics has been implemented by pumping a fraction of the gas from the container through a bypass circuit with an active charcoal filter that adsorbs volatile anesthetics. The flow through the bypass circuit is generated by a pump and is controlled by a linear valve.The resulting performance of the patient simulator has fulfilled the requirements.
K?NSLOR OCH BYGGNADER. Hur f?r?ndringar i den byggda milj?n p?verkar v?r k?nsla f?r plats.
This bachelor thesis aims to explore the public?s personal connection and attachment to place, as well as their
perception of changes in the built environment that has occurred in close proximity to the area. Based upon a
questionnaire carried out in a public square in Gothenburg, namely J?rntorget, the study examines the impact
of the construction of two high-rise buildings that was initiated roughly five years ago adjacent to the square.
The essays theoretical framework is based on the concept sense of place, a concept which derives from the
discipline of Geography. Sense of place encompasses the relationship between people and spatial settings,
which includes e.g.
Två år efter restaurering:Vad har förändrats i bottenfaunan?
The aim of the study was to examine if the benthos in a restored portion of a small lowland stream south of Linkoping differed from two non restored reference areas two years after restoration. The reference areas were one stretch downstream and one upstream stretches of the restored stream. The benthic invertebrates were collected using standardized kick sampling. In order to classify the communities and estimate any differences, three different indices were exercised. In addition rank-abundance curves and checklists were used to get a picture of species composition.
Predation på evertebrater under tidig vår i sjön Tåkern
Benthic invertebrates play important roles as feeding resources for many organisms in different food webs. Shifts in predation of these organisms can generate cascading effects and potentially lead to the disappearance of one or more species from a site. Cascading effects can bring impacts to organisms who aren?t even directly involved, why studies in this field are important for understanding sudden changes in ecosystems. I examined the predation from fish and waterfowl on benthic invertebrates in the shallow and eutrophic Lake Tåkern in the plains of Östergötland County, southern Sweden.
En ?vergiven torpmilj?. Materiella och immateriella l?mningar fr?n torpen kring Brunnslid i Kinneveds socken, V?sterg?tland.
This essay presents an investigation of the ruins of an assembly of crofts in a rural area in the south of Sweden, outside the town Falk?ping. Using literary sources and intangible sources, and then combine them with the information found by investigation of the physical remains of the crofts, the essay attempts to capture the life and the living conditions of the crofters. The investigation is focusing on the period between the nighteenth century and the first decades of the twentieth century, and looks into the the living conditions according to, for example, the buildings, the orientation in the landscape, demografical changes, the transformation of the area over years and how the crofters were affected by powerty.
The investigation shows that the crofters in many ways were in vulnerable and exposed positions, powerty summarized as a lack of freedom ? concerning economical, political and social dimensions.
S:t Göransområdet : gestaltningsprogram för ett stadsutvecklingsområde på nordvästra Kungsholmen i Stockholm
North Western Kungsholmen in Stockholm is confronting big changes and Stockholmsstad is planning that the area will be an extended part of the existing structure in centralStockholm. Dwellings and offi ces are built and the population increase heavily. Th isresult in a need to look at how public green areas can develop and be designed. Th epurpose is to design a proposal for a master plan of S:t Göranområdets public greenareas. Exploateringskontoret, Stockholm stad, who has initialized the task, claim thatthere is a need of clarifying and shield the qualities in the green areas of today and howto create new green structure.The problem formulations which are current in this master thesis are:? Is there a need of a distinct identity for the green areas of S:t Göransområdet? If so,how is this created?? How can the green parks and nature areas inside S:t Göransområdet be improved anddevelop?? How can the connections between the green areas inside S:t Göransområdet beclarifi ed and how can they connect to the surroundings?To get inspiration and information for the design this thesis include a study of theincluding parts in the design process.
Recipientundersökning av Ensjön : Bedömning av sulfidmalmgruvan Enåsens eventuella påverkan på sjöns vattenkvalitet
Ensåsengruvan is a mine situated within Ljusdals municipality in central Sweden. Themine was in use from 1984 to 1991 and has since been undergoing a remediation program. Mine tailings from sulfide rich ore is a potential environmental hazard due to its tendency to cause acid waters and heavy metal leakage. Lake Ensjön is situated one kilometer from the mine area. Due to the hydrological conditions it was not expected to receive inflowing water from the mining area.
