Energihushållning och varsamhet för äldre byggnader : Chefsbostaden i Strömsholm, ett timmerhus från 1900-talets början
This report is the result of a degree project in building engineering, at an advanced level. The project evaluated a building from a technical and historical point of view, and focused on its energy consumption, particularly the energy used for heating. The building in question was a small apartment building in Strömsholm, Sweden. It was made in 1902, from vertical logs, a not so common form of the traditional log house. The goal of the project was to evaluate if the energy consumption could be reduced in accordance with building preservation regulations, that is without damaging any of the building?s cultural or historical values.The building was surveyed with the help of archive and literature studies, interviews and inspections.
Småvatten då och nu : en förändringsstudie av småvatten i Skåne och deras kväveretentionsförmåga
Wetlands play an important role in the ecosystem. They reduce the impact of flow flux in the drainage area, acts as upholder of biodiversity, as an esthetic and recreational component in the landscape and they have the ability to reduce nutrients such as nitrogen, and help preventing eutrophication in costal areas.The number of wetlands in Scania have, due to the intensified agriculture been reduced to maximize the area suitable for crops.However since the mid 80th the consequences of this has been acknowledged, and many wetlands have been restored.This master?s thesis aim to see what impact this development have had on wetlands in Scania over the last 60 years. And also look at some of those factors important for the efficiency of nitrogen removal in wetlands. During the process a detailed manual for inventories of this sort was created.The material used to execute the inventory of wetlands where aerial photographs over Scania from the 1940th, 1980th and 2000.
Energibalansen för ett nytt flerbostadshus i Mellansverige : Beräkningar intervjuer och analys av energikraven i Boverkets Byggregler
Abstract This degree project comprises 30 credits, i.e. 20 weeks of work. The work mainly deals with the energy balance for a multi-family house in Västerås and the requirements for energy conservation in the Swedish building code, BBR. Calculations of the energy balance are supplemented by a number of interviews. Energy conservation in general has become more important in recent years and the subject is in line with increased public awareness. This importance and attention is explained by environmental problems in general and global warming in particular, but also by rising energy prices.
Energieffektivisering i ett verkstadsföretag : En analys av energibesparande åtgärder samt uppvärmnings- och kylsystems driftkostnader och koldioxidutsläpp
The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.

Regulatory approaches? influence on environmental agencies internal quality
The increasing public concern regarding the government?s priorities in spending public resources puts pressure on public organisations to address quality issues in their practice. In United Kingdom both BRTF (Better Regulation Task Force) (BIS, 2005b) and the Hampton report (BIS, 2005a) highlighted management and quality problems in public organisations in UK. These reports revealed obstacles within institutions? intent to offer recommendations and appropriate solutions for agencies working with legal enforcement and control.
Växtinventering och skötselåtgärder : en studie av Rektorsgårdens trädgård i Uppsala
The Bovine respiratory syncytial virus (BRSV) causes bronchiolitis and interstitial pneumonia, predominantly in calves, and is a major cause of bovine respiratory disease worldwide. In humans, BRSV is paralleled by the closely related Human respiratory syncytial virus (HRSV), an important cause of respiratory disease, most severe in infants.The clinical signs and pathology during RSV infection is caused, not only by the direct effects of viral replication, but also by the response of the host immune system. The immunopathology of RSV has long obfuscated our understanding of the disease, and development of effective treatment and vaccines will be very difficult until greater knowledge is gained.One of the components of the immune system that has come into focus in RSV research the last few years, is the Toll-like receptor 4 (TLR4). The TLR4 receptor is well known as the receptor that binds lipopolysaccaride (LPS), and initiates the host response to bacterial infection. Recently, it has been shown that the fusion protein of RSV also interacts with, and up-regulates the expression of, the TLR4 receptor.

Utvärdering av lockmedel för marklevande predatorer under midvintermånader i Norrbottens inland
Many invasive species propose a big threat against the native fauna in the area that they colonise. Today the raccoon dog (Nyctereutes procyonoides) is speeding from Finland over the border in to northern Sweden. A project to stop the spread and eliminate the individuals that already have established was initiated in the autumn of 2008. To investigate areas that might be interesting for raccoon dogs and to confirm sightings, cameras with auto triggering mechanisms are used. To get the raccoon dog in front of the camera some kind of lure is used.
In this study three kinds of different lures was tested against each other?s.

Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.
Näthat : I gråzonen mellan straffrättsligt ansvar och yttrandefriheten
The following thesis concerns the conceptualization of openness within the open access movement. Open accesscan be understood as a phenomenon or a movement that aims at changing the current system of scholarly communication.Consequentially, the movements goals arose in relation to the escalating serials crisis in scholarly communicationand the increasing power of commercial publishers. The purpose of the thesis is to study three centralopen access declarations with the aim of uncovering the different conceptualizations of openness found withinthese texts. Leaning on the theoretical position known as actor-network theory, the declarations role within a surroundingnetwork is explored by focusing on how openness as a concept has been produced and reproduced bycentral actors. Two overarching questions frames the study: How is openness conceptualized within the declarations?And how can openness, as a concept, be understood as an effect generated by a larger network?The first part of the study focuses on the first question.
