Investeringsbedömning av energieffektiva småhus i trä

The purpose of this essay is to describe how Boverkets Byggregler has affected the cost ofnewly built houses from 2003 to 2012, to Boverkets Vision 2025. The purpose is also to findagent-principal relations in the construction sector.When investing in an energy efficient house the operating costs are reduced compared to aconventional house. But due to the lower operating costs, the investment cost rises. In thisstudy, we find out if it is economically viable to invest in an energy efficient house comparedto a conventional house from the customer's perspective.The study's approach has been qualitatively where we in collaboration with Derome Hus hadaccess to three conventional reference houses and a passive house and data that was necessaryto conduct viability assessments on houses. We conducted five interviews with people fromDeromekoncernen and Varbergs kommun.The calculation methods we have used in this study are present value method, annuity methodand a sensitivity analysis.

Motivation för lärande : En intervjustudie om vad lärare gör för att skapa motivation vid matematikundervisningen i årskurs tre.

Inom nuklearmedicinsk diagnostik används radioaktiva läkemedel för att utvärdera olika organs metabolism och fysiologiska beteende. Genom att använda en scintillationskamera kan strålningen som erhålls när det administrerade läkemedlet sönderfaller i kroppen detekteras och en funktionell bild över aktivitetsfördelningen erhålls. En tredimensionell bildvolym kan erhållas om gammakameran får rotera runt patienten vilket kallas SPECT (Single Photon Emission Computed Tomography). Bildernas kvalitet är av stor betydelse för att kunna göra en noggrann bedömning av olika patologiska tillstånd. Kvaliteten begränsas av en mängd faktorer och en av dem är Comptonspridda fotoner.I denna studie optimerades bildkvaliteten för SPECT-undersökningar med 111In-Octreoscan för ett Infinia Hawkeye 4 (GE Healthcare, Wisconsin, USA) SPECT-system vid Norrlands universitetssjukhus (NUS).

These studies are followed up in order to see if measures have been taken.The report presents a number of arrangements which should be taken, amongst those a minor re-build of the current solution and a number of arrangements which leads to decreased water consumption..

Uttag av energisortiment vid gallring av contorta, ett komplement till konventionell gallring? :

A recommendation for stand treatment of lodgepole pine (Pinus contorta) is, in a scientific point of view, lacking when it comes to harvesting for biomass energy. Within the next decades it is expected that 280 000 hectares of lodgepole pine will have reached thinning age on the domains of Svenska Cellulosa Aktiebolaget (SCA). Due to this the interest has grown rapidly for studying the possibilities of harvesting biofuel assortments already in the first thinning. In this study the distribution of the biomass within lodgepole pine trees has been studied and taken into account for estimating the proportions of harvested assortments when using different methods of thinning. The methods studied were conventional biofuel-harvesting (with delimbed branches gathered separately from the round wood) and thinning with cutting of round wood and long tops (incl.

Kulturellt relevant socialt arbete? : En fältstudie i en SOS-barnby, Swaziland

The purpose of this study was to examine how SOS Children's Villages as an organization in Swaziland is affected by, and takes into account, the cultural, organizational and societal context in which it acts. Material was gathered through a field study during one month in one of the three SOS Children's Villages in Swaziland. The study has a qualitative approach and is based on the result from 12 semi-structured interviews with village mothers and other representatives from the organization. The other representatives were: social worker, program director, child and youth development coordinator, board member and educational manager. Since this study is both characterized by a specific historical, cultural and organizational context, we decided to connect the postcolonial perspective with an organization theory with focus on the concepts of culture, power and a children?s right perspective.

Vindkraft och landskap

The current debate about environment and climate change has contributed to more andmore investment in alternative energy sources such as wind, solar and biogas. The Swedish Parliament has set the target that wind power should supply 10 TWh in 2015.In Sweden, wind power establishment began in the early 1980s. Since then the development has gained a tremendous momentum. The purpose of this study was to find out what problems wind power brings and what power relations that exists in connection with wind power establishment and how the landscape is affected by windpower construction, focusing on some cases in Falkenberg and Varberg. This study shows that wind power establishment is a very complicated process.

Äggstockscysta hos mjölkkor

The presence of cystic ovarian follicles represents an important ovarian dysfunction and is a major cause of reproductive failure in dairy cattle. A cystic ovarian follicle is a persistent follicular-like structure on one or both of the ovaries. It is at least 2,5cm in diameter and it has to persist for at least ten days while a corpus luteum is missing. There are two kinds of cystic ovarian follicles, those who have a progesterone production and those who have not. A clear definition for this condition is lacking, probably because the heterogeneity of the clinical signs and the complexity of the disorder.

Analys av system för rening av avloppsvatten i en anaerob membranbioreaktor

The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.
