Passiva lantbrukare ? en effekt av EU:s jordbrukspolitik : en studie av ett antal faktorers påverkan på svenska passiva lantbrukares attityder till markanvändning och EU:s jordbrukspolitik
The problem with passive farmers has arised as an effect of the European Union´s common agricultural policy (CAP) and the decouplement from production-based payments. Payments to passive farmers contradict the purpose of the single payment scheme and constitute a great cost for the EU. The new contractual period after 2013 has given rise to discussions on the direction of the CAP with a purpose of increasing the efficiency of the single payment scheme, and reducing passive farming. The aim of the study is to increase the knowledge about a few factors? influence on passive farmers? attitudes towards land use and the CAP.
Lysande rör, rörligt ideal : belysningsbranschens introducerande av lysröret i Sverige
During the 1930´s the hot potato for the Swedish lighting associations were how to create the most suitable light for every situation, either for industries, offices or homes. The light bulb were the most frequently used source of light but due to limitied luminous intensity, big halls sometimes required up to hundreds of light bulbs to produce the right amount of light. Two kinds of different lights, by different reasons, can be titled the predecessors of the fluorescent lighting during the 1930´s: The volfram-filament tube light due to its estetic similarities and the electric discharge (mercury- and sodium-) lamps due to its technical resemblance. Even though they came in quite wide use (the volfram tube in public halls (e. g.
Teknikutvecklingens påverkan på energianvändning i byggnader under 100 år
Detta examensarbete i energiteknik har utförts på uppdrag av företaget ABB och avdelningen Energy Efficiency under våren 2013. Syftet med arbetet är att ta fram ett underlag för energianalyser där åtgärder kan föreslås och prioriteras efter ålder på byggnader.

With the reorganization, VGLS started a project regarding responsibilities around railway flows. Within the project a demand to collect logistics requirements occurred.
Simulering av COD-fraktioner i en aktivslamanläggning vid en sulfatmassafabrik
This thesis work was made for Södra Cell Mörrums bruk in Blekinge. The purpose of the work was to develop a computer model in the simulation program Extend for the removal and balance of organic oxygen consuming substances, measured as COD (Chemical Oxygen Demand), in the new biological treatment plant in the mill. The plant produces two different pulp products, TCF- (Totally Chlorine Free) pulp and ECF- (Elementary Chlorine Free) pulp, for sale. The different bleaching procedures affect the characteristic of the wastewater and thus the effectiveness of the biological treatment plant.In the model that was developed the COD in the wastewater was divided into five different COD-fractions: soluble easily degradable (SS), soluble hardly degradable (SR), soluble inert (SI), particulate inert (XI) and particulate biomass (XB). To create the model FlowMac? was used as a base.
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.
