En kartl?ggning av inv?ndiga f?nsterluckors utbredning och konstruktion
Interior window shutters can be found in historical buildings, but they are an uncommon occurrence in
modern buildings. In modern contemporary construction, large glass panels are often the ideal because
of increased light inflow and for architectural purposes. However, this can generate several negative
effects, such as increased energy loss, lack of privacy and high sunlight penetration. Problems that
window shutters could have accommodated historically.
This thesis identifies a lack of knowledge about interior window shutters in the Swedish building
stock.
Ipv6 : En empirisk studie i hur Ipv6 protokollet har utvecklats de senaste åren.
Internet grows, so it?s cracking, soon will all IPv4 addresses be allocated and a solution is urgently needed. The new protocol, IPv6 is the solution to this problem. With a size of 128 bits against IPv4s 32 bits gives IPv6 a huge amount of addresses to distribute. The security addition that may be added manually in IPv4 is the standard with the new protocol.
PBL som ledstjärna? : Lärares reflektioner kring möjligheter, förändringar och utmaningar med Problembaserat lärande
This survey aims to investigate and analyze how six teachers on a high school in Stockholm reflect on pedagogical aspects of problem based learning( PBL). The survey focuses on ana-lyzing how the teachers relate to the benefits and problems of PBL and how they reflect on the students development. The survey was conducted on a high school and the method used for the study was interviews, each taking 30-45 minutes. The outcome of the survey indicates that the teachers sees problem based learning as an alternative to what they define as tradi-tional education regarding its epistemology. They indicate that PBL allows the students to define their own questions, to be carriers of knowledge and to evolve analytic skills in relation to the basegroup.
Majsensilage i Sverige
Maize for silage has been used as fodder in different parts of the world for a long time and has recently become more common also in Sweden. Our cold climate has been a problem as maize is very sensitive to low temperatures and frost. With new varieties and better techniques for cultivation it is now possible to grow maize in the southern and middle parts of Sweden. As for the north of Sweden the length of the cultivation season is a limiting factor as there are too few days with temperatures of over +10 ºC. Maize is well suited for silage making but oxygen-free conditions are required.
Handarbetets sociala rum - om emotionshantering och kollektiv identitet i handarbetsrörelsen
The purpose of this thesis is to investigate emotions and collective identity in the handicraftmovement. Which are the collective identities of craft movement, and is it possible to speak ofan over all collective identity among the handicraft people? I will also examine the emotion workboth on individual and group level.Eight qualitative interviews were conducted to achieve the aim of this thesis. Research haspreviously drawn attention to handicraft from a gender and a historical perspective but neverfrom an emotional one. The theoretical framework derives from an emotion sociologicalperspective where Collins interaction rituals, emotional energy and Hochschild?s emotionmanagement is the main theses.
Är OSSg2 ett lämpligt steg mot Open Source på verksamhetskritiska IT-system?
Sun Microsystems chose its own Open Source path by not following competitors in their commitment toGNU/Linux. Sun instead created its own Open Source project from the source of Solaris under the name ofOpenSolaris. The business model of OpenSolaris belongs to the new and more commercially viable OpenSource, referred to as OSSg2. This survey was based on articles on the adoption of Open Source in organizationsand István Orci?s publication Kritiska IT-System.
Factors for success in Swedish biogas : a study based on the Swedish agricultural sector
The energy sector of modern time is currently faced with several challenges. These are both production oriented and environmental oriented in nature. The energy of the future is intended to support an increasing demand while at the same time reduce its environmental affection. This stresses a development towards production methods of renewable energy. Among the existing methods, biogas is presented as an attractive alternative.
Vindkraftsplanering i skogsmark
The aim of this study about wind power planning in forest was to examine the factors and restrictions, which represent technical limitations, biodiversity, tourism and amount of energy for wind farms in Kronoberg County. Suitable areas for wind power were identified from the collected information about planning principles and potential conflicts. From the suitable areas the potential energy gain is calculated. Methods used were mainly a literature review, interviews with experts and practitioners, GIS analysis and a rough calculation of the energy gain. The section of information and facts describes in general wind power planning and possible conflicts.
Biogasprocessen : Bestämning av verkningsgrad
Biogas is increasingly used for fuel in for example vehicles and it´s produced in a biogas processconsisting of the steps of pretreatment, digestion and gas cleaning. The pretreatment is a method usedto increase the gas production and / or destroy pathogens. The digestion is the stage when anaerobicmicroorganisms convert bio-mass of a substrate to a raw gas containing about 65% of methane. Thegas cleaning is used to increase the methane content to about 97% so the gas can be used for motors invehicles. The biogas part of the Ekeby sewage plant in Eskilstuna is using multiple substrates.
Energibolagens framtida datainsamling
The Swedish energy companies have several different systems for data collection
of the energy consumption of their clients. Often computerized remote meter
readers are put in practice in order to register the energy consumption of
large companies. The majority of household clients, however, are read off by
the assistance of manual methods.
Household power consumption is read off once a year. As a result, these clients
are not debited for their actual consumption; their invoices during the year
are the result of estimations. At times when the electricity supply system is
highly loaded, electricity is more expensive.
Energiförbrukning för putsade, odränerade träregelväggar i fuktigt respektive torrt tillstånd
In recent years, moisture damages have been noticed in rendered, undrained stud walls. The design is built on the principle one-stage tightening which means that there is no air gap in the construction. The damages have occurred when water has permeated through the rendering in leaking connections and fittings for windows, doors, canopies, balconies, terraces and awnings. Behind the plaster carrier, which consists of either polystyrene or rigid mineral wool, plasterboard has often been used as a wind protection barrier. In many cases the wind protection barrier and the underlying wooden studs have been exposed to mould and in some cases even rot.
Den ärvda utbildningen och det (o)fria valet? : En jämförande studie mellan fem olika program på Örebro universitet
The inherited education and the (un)free choice?- A comparative survey between five different programs on University of ÖrebroThe aim with this paper has been to examine and to report for different sociocultural background factors (class property, the parents' level of education, the parents' income) importance for the choice of type of education and to see if there is any differences between different university courses with respect to class property. Our issues were following:1. What/which sociocultural factors have had most importance for the choice of programs on universities?2.
Undervisa taluppfattning i matematik genom handboken Förstå och använda tal. En studie av ett utvecklingsprojekts start i en skola
The purpose is to explore and describe norms and values concerning emotions and emotional expression inSweden and Greece from an emotionsociological perspective. Do emotional regimes on a national level existand if they do, how do they differ? To answer this question qualitative interviews have been conducted withnine Greek/Swedes, men and women of different ages, who have lived in both countries and who speak bothlanguages. A quantitative survey study, employing a survey previously used in a Swedish study about emotions,has also been undertaken. Previous studies have shown that emotional regimes do differ historically and acrosscultures, but no study so far has focused on the differences between examples of North European and SouthEuropean cultures.The theoretical framework consists mainly of Hochschild´s theories about feeling/display rules and emotionwork, but the analysis also draws on Collin´s theory of interaction ritual chains and on Sociology of Emotionsmore broadly.The results suggest that different national regimes can be distinguished primarily in terms of display rules andin the skills of emotional alternations.
Utvärdering av vattenrening och identifiering avförluster m a p energi vid Bravikens pappersmaskin 53
This Master degree project has been performed at the Braviken paper mill on papermachine 53 (PM53) which produces newsprint paper. The current economic situationhas contributed to declining demand for newsprint, which means it is extra important tobe competitive by high energy efficiency. Particularly as energy prices are expected torise when the economic growth returns.One way to increase energy efficiency is by reducing the water use in paper and pulpmills and consequently save energy through reduced heating of water. The thesis's maintask is to evaluate whether a water purification plant (microflotation plant) forpurification of process water in PM 53 is profitable. The microflotation plant enablesreuse of warm process water instead of losing the energy to receiving waters.
EN FALLSTUDIE OM URBAN VINDKRAFT VID ALBANO
The use of energy is an important question in today´s society, and a substantial part of the energy that is used today is used in our homes. To lower this usage is vital, and there are regulations in place both on the national and the local level, that say that new apartment blocks must be built to consume less energy, which in the end will lower the impact on the climate.One way to make the housing sector more environmentally sustainable, is to produce energy issions that are bad for the environment, for example to build wind turbines close to or even on the buildings, so called urban wind power. The scope for this report is to see if urban wind power could be a sustainable alternative for the residential area that Svenska Bostäder plans to build in Albano in Stockholm.There are extensive scientific theories regarding wind and wind power, and a literature study is made to investigate past knowledge in the area. Efforts have been made to find earlier trials with urban wind power and, both scientific research and trials where urban wind power actually has been installed. The theory chapter deals both with the wind itself and how electricity can be generated from wind.
