Varför uppförs så få bostadsrätter med passivhusstandard i Sverige? : En fallstudie mellan ett passivhus- och en konventionell fastighet
Abstract Background: In 1997 the Kyoto Protocol was signed, it?s an international agreement which is aimed to reduce greenhouse gas emissions. Sweden's goal is to reduce energy using in buildings with 20 percent by 2020 and 50 percent by 2050. This is a comparison with levels from 1995 (Glad, 2006). For Sweden to be able to reach its goals, they need to construct more low-energy buildings (Åhman, Wahlström & Lundblad, 2010).
Intellectual Property Rights : A Barricade to Technological Development. An Ethical Analysis on the Less Developed Countries
Debate over Intellectual Property Rights ?IPRs? particularly patent and copyrights is mainly on forward-looking industries in computer software. As part of a trade deal reached in 1994, the member nations of the World Trade Organisation must adhere to a global agreement known as TRIPS, for the Trade- Related Aspect of Intellectual Property Rights.This study is to analyse the ethical conception of Intellectual Property Rights and in particular its implications on the developing countries in relation to TRIPS. The approach will be to analyse a broad philosophical theories of property to see if there is any justification for a software program to be treated as private property and also argue base on John Rawls two principles of justice in relation to TRIPS Agreement. Some reflections will be put on the use of open-source software by less developing countries.From the study it was asserted that, strong IPRs protection would hinder technological transfer and indigenous learning activities in the early stage of industrialisation when learning takes place through reverse engineering.
Den offentliga kulturmiljövården och miljonprogrammets bostadsbebyggelse
The intention with this essay has been to examine how the public instances working with cultural heritage in Sweden deals with the housing built under the period of the so called miljonprogrammet (?the million programme?) during 1965-75. The interest in the built environment from the 1960s and 70s has increased in the last ten years within the field of cultural heritage. The purpose with this study is to examine which cultural values that are assigned to the housing of the million programme. The purpose is also, as mentioned before, to study how the field of cultural heritage deals with this type of built environment.
Laborationsmätning av vindtäthetens betydelse för en väggs U-värde
To fulfill the climate target that EU and the Swedish government have decided to apply, it becomes increasingly important that the energy efficiency of existing buildings and making new buildings energy efficient as possible. Of Sweden?s total energy consumption in 2011 was 40% used by residential and service. Of the 40% of the energy consumption was 60% used for heating and domestic hot water. A report from year 2012 shows that one reason why the heating volume is so great could be due to underestimating on the energy consumption for the heating in the planning of the building.
The Cost Saving Potential of Standardization, -a study at a global packaging company
To introduce a standardized component assortment takes a lot of effort in order to make real cost savings. The rationalization effect itself is important, but perhaps even more important is to state the aim of the standardization efforts in a well-defined way. How can an organization assure that they are working in a proper way? How do they know that their efforts are being interpreted into the whole organization? And, how do they know that the standardization efforts actually save money? Different components differ heavily e.g. in technical complexity and quality issues.
Fyra västsvenska mediers syn på pressmeddelanden
Today most people are in agreement that the media industry is in crisis. Many newsrooms cut down on staff. At the same time the PR industry is growing. We wanted to research if this could affect the unbiased and independent news in our news media today. Today's newsrooms receive a lot of press releases every day.
Optimering av sotningsfrekvens i biobränsleeldad CFB-panna : panna 5, Mälarenergi AB, Västerås
During the past 30 years the fuels for energy production in heating and power plants
have changed. Fossil fuels have decreased in usage whereas bio fuels in Sweden
have increased with 60% since the 1970's. Different fuels affects combustion and the
release of various substances and particles into the flue gas. This is caused by the
diverse components and chemical structures of fossil fuels and bio fuels. When the
flue gas leave the combustion chamber and enters the path to the chimney particles
in the gas are being transported out of the combustion chamber.
C. M. Carlanders Svenska bibliotek och ex-libris (1904): En källkritisk studie av kvinnors bibliotek under tidigmodern tid.
The aim of this study is to examine the historical information about women?s libraries and book ownership during the early modern period in the work of Carl Magnus Carlander, Svenska bibliotek och ex-libris [Swedish libraries and ex-libris] (1904) and to inquire the scientific value of the information. A gender perspective is applied to the study. Gender is understood as a social and cultural constructed concept, dealing with female and male identities as interdependent categories.The study of Svenska bibliotek och ex-libris is made using source criticism and it has two parts. The first part deals with external conditions of the creation of the work; the life of C.
Konstruktion av patientsimulator för anestesimaskiner
A patient simulator for testing anaesthesia machines has been developed at Maquet Critical Care AB, to reduce costly and time-consuming experiments on animals. The device simulates human lungs regarding lung dynamics and volume, uptake of anaesthetic agents and the production of carbon dioxide, heat and moisture. Further demands on the simulator are durability and size; the device shall be compact enough to be moveable.The resulting simulator fulfils the requirements and enables better repeatability and ability to test extreme cases than experiments on animals do.Uptake of the anaesthetic agent is achieved in a active carbon filter and controlled by regulating the flow. The flow is created by a regenerative blower and controlled using a proportional valve. The uptake can be set by the user or by a simple uptake model modified to recursively handle changes in the concentration of anaesthetic agent.Carbon dioxide is fed into the system from a tank by a mass flow regulator.
Användning av rötrest från kombinerad etanol och biogasproduktion : en jämförelse mellan tre alternativ
Scandinavian Biogas is involved in the planning of a combined ethanol and biogas factory in Karlskoga, Sweden. Besides biogas and ethanol large amounts of digester residues will be produced, about 450 000 liquid tonnes residue (~7,3 % Dry Substance( DS)). The objective of this thesis was to investigate possible uses of the residue from the biogas production process ScandgasEthanol developed by
Scandinavian Biogas, and to derive a methodological approach how to evaluate and compare handling systems. Three systems where proposed and compared in this thesis; spreading of the untreated residue as fertilizer (system 1), dewatering to a higher DS content to reduce transportation before spreading as fertilizer
(system 2) and production of a solid fuel by dewatering and drying the residue (system 3). The general conditions for the proposed systems were investigated in
terms of practical viability, economical aspects, environmental impact and energy inputs/outputs.
Klienten som kunskapskälla : En kvalitativ studie om socialsekreterares kunskapskällor och kunskapsanvändning
The aim of this study was to describe and analyze how social workers working in social services using evidence based practice with special focus on the clients? experiences and wishes as source of knowledge in collecting information, assessment and decision. To get to the social workers experiences and descriptions we used a qualitative method with semistructured interviews. The empiric material of the study consists of eight interviews with social workers working in different social offices in different areas, in southern Sweden. The main result of this study was that social workers use clients? experiences and wishes differently in different parts of the investigations.
Silver och vismut i plaster och färger : Källor till förhöjda halter i slam?
Chemical substances are spread diffusely and uncontrollably as a result of the increased consumption of goods. REVAQ is a certification system that works to reduce the flow of hazardous substances to Swedish treatment plants and to create a sustainable nutrient recycling. According to REVAQ, the yearly accumulating rate of metals should not exceed 0.2% in soil per year. Silver and bismuth are two metals that do not fulfill this requirement. The silver concentration in sludge decreased during the last decade, however the last few years, it has leveled off.
Upplevelser hos socialsekreterare som arbetar med barn och unga inom myndighetsutövning : - En studie av kritiska incidenter
AbstractWorking with child and youth welfare is one of the most difficult challenges a social worker might face in the field of social work. Those who work with child and youth welfare are more exposed to stress and burnout than other comparable human service occupations. Research links the prevalence of stress and burnout to several key variables, such as demographics, working conditions and personality factors. In contrast, even though social workers in this field face many negative work-related problems they report a high job satisfaction. The aim of this study is to examine how uplifting and straining experiences affect social workers, who work with child and youth welfare, through the use of The Critical Incident Technique and interviews.
På tal om källor: En studie av lärarstudenters informationsanvändning i examensarbetet
The purpose of this Master?s thesis is to investigate the information use in teacher education students? degree projects. The first study is a reference analysis used to categorize the cited sources in 33 degree projects from the teacher education program at one Swedish university. The aim was to find out what types of sources were used, in particular the amount of citations to scholarly publications. The results of the reference analysis showed that the majority of sources used were text books.
Kulthus och deras hallar : Ett arbete om förhållandet dem emellan
This is a work about the relationship between cult houses and halls. In my essay I will go through four different places were cult houses and halls both exist. I will look at the findings and the landscapes were the settlements are located in. The places I have chosen are Lunda in Södermanland, Slöinge in Halland, Uppåkra in western Skåne and Järrestad in southeast Skåne. Because of that the cult houses and halls are occurring during the late Iron Age, it is during this time period that I will work in.
