Ingenjörkompaniet i urban miljö ? ett historiskt perspektiv på nutida förmågor
Urban operations is one of the most difficult challenges a modern army can be tasked with. These challenges have been studied in history and present with various perspectives, but rarely from a combat engineering point of view. The purpose of this thesis has been to study the urban capabilities of a Swedish combat engineer company by examining if it can perform similar combat engineering fieldwork that supported the basic capabilities mobility, defence and effect in Operation AL FAJR, Fallujah Iraq 2004. These are the capabilities a Swedish engineer company are primarily designed to support in urban operations.For example, the study of Operation AL FAJR has shown that fieldwork supported mobility with breaching minefields, obstacles, walls and doors. Defence by creating defensive positions and obstacles.
Riskanalys för Göteborgs vattentäkt med avseende på förorenade områden längs Göta älv
Today more effective computer programs are in use, regarding design of geotechnicalconstructions. There is a risk that the theoretical background of the computerprograms, its limitations and the signification of the choice of soil parameter isforgotten when the computer programs become more user-friendly.This Master thesis deals with simulation and analysis regarding three computerprograms, FEM-design, with the addition Raft, Plaxis and BE-slab. Comparisons aremade for settlement and maximum moment in a concrete-plate. FEM-design is a threedimensional FEM-program, foremost created for design engineers. Plaxis is a twodimensional FEM-program, intended for geotechnical engineers while BE-Slab is aBoundary elements program in two dimensions that is mainly used by designengineers.

Fri rörlighet av varor : Art 34 FEUF och åtgärder med motsvarande verkan - "från Dassonville till Trailers målet"
The characteristics of free movement is the elimination of obstacles to trade between Member States and thus by such, create free movement within the entire union. Therefore art 34 in the Treaty of Lisabon (FEUF) states that all quantative restrictions on imports and measures of equivalent effect are prohibited. The legal approach to measures having equivalent effect is still unclear and the purpose of this paper is therefore to propose a solution to that particular problem. What can be said when it comes to this rule is that the EU-Court has gone from applying a discrimination test to a market access doctrine.According to the Court´s case law, measures having equivalent effects to quantative restrictions are ?All trading rules enacted by Member States which are capable of hindering, directly or indirectly, actually or potentially, intra-community trade?. The question of how to apply the test when it comes to a potential hinder to intra-community trade is still unclear.
Värmeisoleringsberäkningar av flerbostadshus : byggda 1996-2005
År 1987 trädde en ny byggnadslag i kraft, Plan- och bygglagen(PBL). I och med den nya lagen minskade kommunens och byggnadsnämndens kontroll av projekteringshandlingar och besiktningar ute på arbetsplatsen. Efter lagändringen beror den slutgiltiga kvaliteten på en byggnad i större utsträckning på byggherrens och entreprenörernas egenkontroll. P.g.a. olika intressekonflikter inom kommunen, och att det kan förekomma starka kopplingar mellan byggherre och entreprenör, är det inte alltid självklart att kommunens tillsyn vid nybyggnation gällande till exempel egenskapskrav på energihushållning och värmeisolering utförs tillfredsställande.Med ovanstående i åtanke undersökte vi fyra flerbostadshus, två i Värnamo kommun samt två i Kristianstad.
Studie av värmeflöden i befintligt bostadsbestånd : Utvärdering av energieffektiva besparingsåtgärder
The purpose of this master thesis is to investigate different types of measures for making buildings more energy efficient and to estimate their profitability. The calculations were performed with the building simulation program VIP+ and the evaluation of the profitability with the life cycle cost method. Furthermore, it was examined how losses in the distribution of secondary systems of district heating can be avoided. Options to replace district heating with a local district heating system based on bio-energy have been investigated. The possibilities of achieving more efficient thermal energy consumption and production for the chosen estate were also examined.The object of the study has been a residential estate with 133 detached houses in Uppsala, built in 1974.
Neonicotinoids and honeybee health : the effect of the neonicotinoid clothianidin, applied as a seed dressing in Brassica napus, on pathogen and parasite prevalence and quantities in free-foraging adult honeybees (Apis mellifera)
Sub-lethal doses of neonicotinoids have been shown to negatively impact the health of honeybees. However, most studies to date have exposed bees only artificially to these pesticides under laboratory conditions. There have been just a few well designed and replicated studies of the
impacts of realistic neonicotinoid exposure on honeybees foraging under field conditions. In order to close this knowledge gap, and to test the influence of the neonicotinoid clothianidin on honeybees, we used a study system of 16 paired, spatially separated (>4 km) spring oilseed rape fields in the south of Sweden. The fields were paired according to land use, the surrounding landscape and
geographical proximity, using GIS.
IFRIC 15 : och dess påverkan på byggföretagens intäktsredovisning
The number of studies on IFRIC 15 is very limited. The available studies have either been conducted before the introduction of IFRIC 15 or at an early stage of the implementation. This study examines IFRIC 15s practice from a longer perspective. The purpose of this study is to explain the effect that the interpretation IFRIC 15 has had on accounting objectives and qualitative characteristics of the revenue recognition of Swedish construction companies. The study will also analyze whether the construction companies has changed their perception of IFRIC 15 after applying it form a longer time perspective.

The objective of this examination paper is to study the impact of non-monetary factors on the values of forest properties in Sweden. This study is based on a population of buyers of forest properties in the southern of Sweden. The results are based on interviews with 54 buyers. Of the purchases were 37 % new purchases.
Hastighetskameror ? ett brottsförebyggande och normskapande styrmedel? : enkätundersökning kring hastighetskameror
Title:?Speed cameras - an prevention of crime and a standard forming instrument of control??Authors: Markus HanssonTutors: Bo Isenberg & Carl HultExaminator: Ulf DruggeThe School of Human SciencesUniversity of KalmarThe studys purpose is to get a absorbed understanding for peoples attitude, and effect of speed cameras. The disposition for the study is to integrate earlier studies in the matter, combined with elevating interesting sociological conceptions. As an attempt to understand speed cameras as an instrument of force on the individual have Michel Foucaults concept Panopticon been used to see its effect, and it?s look upon how crime prevention will be formulated, which can give an explanation of why speed cameras are being used as an instrument of control on the traffic area.
Ursprungsmärkt : En studie om konsumenters betalningsvilja fo?r ursprungsma?rkta livsmedelsvaror
This bachelor thesis argues for consumers' views on origin labeling effect and their willingness to pay for goods with this kind of label. The purpose of this study is to analyze the factors that influence and to measure willingness to pay for a national origin labeled product previously only competeing with a less expensive conventional product, when a further regional product is introduced in the purchasing decisions of consumers. This is achieved by testing whether Simonson's (1989) theory of the compromise effect is applicable to increase consumers' willingness to pay for eco-labeled food products. The factors affecting the willingness to pay; trust in eco- label, opinions about the products of their own nation and the surrounding region. Furthermore presents theory about what underlying the consumer consumption choices.In order to achieve credible results 240 respondents have participated in a questionnaire survey.
Kalvhyddans utformning : påverkan på kalvens hälsa och komfort
This paper aims to, through a literature review, examine how to best design and adapt calf huts to meet the calf's physiological requirements and reduce the infection pressure for enteric and respiratory diseases. It illuminates how the calf relates to different temperatures and climate, which temperature control mechanisms it uses and its ability to perform these regulations, as well as providing a summary of the past decades´ research on the calf huts housing system. These two theory chapters, along with a concluding discussion, provide a better understanding of how to, especially in temperate climates, design the most suitable calf hut, which cater to the calf's both thermal comfort and physical health. The literature suggests that the calf's own temperature control works well to counteract the temperature outside the desired range, and that one of the most important factors rather is ventilation of a calf hut, which reduces moisture and pathogens. The conclusion of this paper is mainly that there is not an obvious way to place and construct a calf hutch and that most design principles contribute to both positive and negative effects simultaneously.
