Energideklarationer i flerbostadshus i Gävle
Syfte: Syftet med uppsatsen är att undersöka hur energideklarationen har tagits emot och påverkat fastighetsägares arbete med energifrågor i flerbostadshus i Gävle.Metod: Denna uppsats baseras på kvalitativa intervjuer med fastighetsägare i Gävle. Fastighetsägarna som har medverkat är från den kommunala och privata hyressektorn samt kooperativa bostadsrättsorganisationer och privata bostadsrättsföreningar. Intervjumaterialet har sammanställts i fem olika kategorier i löpande text med förtydligande tabeller och diagram.Resultat och slutsats: Endast tre av de sju tillfrågade fastighetsägarna är helt färdiga med energideklarationerna. Alla respondenter anser att energideklarationen är bra över lag, men det finns även flera saker som de anser är negativt med energideklarationen. Majoriteten av respondenterna anser att de inte har gjort några större förändringar i och med den nya lagen, de jobbade redan med energibesparande åtgärder innan energideklarationerna genomfördes.Förslag till fortsatt forskning: I uppsatsen har vi inte tagit hänsyn till de boende och deras påverkan av energiförbrukningen.
Vilometabolism hos barn och ungdomar med Cerebral Pares : En deskriptiv korrelationsstudie
Background: Cerebral Palsy is usually divided into three subgroups: ataxic, spastic and dyskinetic, where children and adolescents can, because of misestimation in nutrition and energy intake, suffer from weight problems.Aim: To compare calculations with equations with the individual's measured RMR in the subgroups, to see if any equation is more suitable. This could be used as a tool to calculate the resting metabolism at times when it is not possible to perform clinical measurements.Method: The RMR has been measured in 37 children and adolescents aged 3-15 years through indirect respiratory calorimetry. Those values have been compared with calculations from five equations. The results were then analyzed in order to find if any equation is better to apply for calculating resting metabolism for each subgroup.Results: The ataxic group was overestimated by 56.5% of the calculated values. WHO/FAO/UNU?s equation indicates a significantly strong correlation between the measured and calculated values (r=0.85, p<0.05).
Utvärdering av vibrationer inom vattenkrafts normer
The International Organization for Standardization (ISO) proposes vibration standards for the evaluation for machine damage due to vibration in rotational machines, where some vibration parameters are given to measure the vibrationgrade. This work evaluates the relevance of the vibration standards in hydro plants that are proposed by the ISO, and also investigates if there are methods used in other countries could have greater importance. Through statistical analysis of collected data we got a better understanding of relation among different vibration parameters, and also the importance of correct choice of the parameters for the evaluation of vibration. We have found that the vibration standards available today in hydro plants are not reliable for the judgment of vibration?s grade.
Mätning av ekosystemtjänster i jordbrukslandskapet :
Abstract
In order to make the modern agriculture less dependent on non-renewable external inputs, it
has to rely more on ecosystem services. The agricultural system produce not only food, fiber
and fuel, it also generates other ecosystem services such as e.g. photosynthesis, recycling of
nutrients, influencing local microclimate, pollination, biological control and detoxification of
noxious chemicals.
This study is an attempt to get a better understanding about the interaction among different
ecosystem services and different habitats capacity to generate them. An evaluation of eight
different methods is done. The ecosystem services studied are the ability to absorb solar
energy, biomass production, botanical diversity, decomposition and natural predation of
aphids.
ENERGI- OCH KOSTNADSEFFEKTIVAMATERIALVAL I VÄRMESYSTEM : En jämförelse av rörmaterial i vattenburna värmesystem

The work is delimited to discusspipes of steel, copper, plastics andcomposites. The aim is that the resultcan be compiled to illustrate the prosand cons of various materials whenevaluating investments.The main object of the survey is part ofa heating system in the office-block KVSommaren located in southern Stockholm.The configured piping system is designedwith the mentioned piping materials andis used to make up the data for flow andcost calculations. The differentmaterials are calculated in both aconventional manner with a supplementarycost for additional fittings and with amore accurate quantification of thecomponents.
För vem är friheten större? - Hur Vellinges politiker tänker i flyktingfrågan
Vellinge is one of few municipalities in Sweden that refuses to accept refugees. The subject of this thesis is to find out how the local politicians in Vellinge make their considerations when they decide not to welcome refugees. The analysis uses the representation theory as a starting point. The two ideals of the representative role, either as a bound mandate or as a free independent role, is the base of the analysis. Vellinge is in the analysis compared to Lomma, a very similar municipality in southern Sweden that for a long time alsohas refused to accept refugees, however suddenly in 2007 decided to change their mind.
Hur anpassar sig Gyps-gamar (Gyps rueppellii och G. africanus) i Östafrika till oregelbunden och osäker födotillgång?
In East Africa live two species of Griffon Vultures; Rüppel?s Griffon Vulture (Gyps rueppellii) and African White-backed Griffon Vulture (G. africanus). One of the apparently most important factors limiting the population of these birds is food supply. Griffon vultures nest for eight months of the year, and are during this period geographically tied down to the nesting place.
Samband mellan hull, underhudsfett, levande vikt och fruktsamhet hos SRB och SLB :
After parturition the energy demand for milk production is greater then the energy provided from the diet. The cow mobilises therefore body tissues to compensate for the energy loss. Live weight and body condition scores decreases as a consequence of the mobilisation.
The aim of this study was to analyse the relationship between body condition score, live weight and subcutaneous fat depth measured by ultrasound and the changes during the lactation. Possible differences between Swedish Holstein (SLB) and Swedish Red and White Cattle (SRB) were also investigated.
Det målande barnet. Diskursanalys av estetiska läroprocesser i relation till Deweys estetiska erfarenhetsbegrepp.
THE PAINTING CHILD. A DISCOURSE ANALYSIS OF AESTHETIC PROCESSES OF LEARNING IN RELATION TO DEWEY´S ART AS EXPERIENCE.The aim of this study is to present a discourse analysis made on five-year-old children during art activities in a preschool in Sweden. The questions asked are: how does interaction take place between the children, or the child and the teacher, during art activities? And what does this tell us about the relationship to art in preschool? In Art as Experience John Dewey claims that art is separated from other experiences of life, but that it ought to be close to ordinary life-experiences. Today visual culture is important in society but not in school.
Nya Slussen i dagspressen : En kvantitativ innehållsanalys och kritisk diskursanalys av Dagens Nyheters, Svenska Dagbladets, Expressens och Aftonbladets rapportering om Nya Slussen
The reconstruction of a central area in Stockholm named Slussen (The sluice) has frequently been portrayed and debated in media over the last few years, escalating around December 2011 when the major decision regarding Slussen was to be made by the city council. The area serves as a traffic node connecting the areas of Södermalm and Gamla Stan (Old town) together. The last major change of Slussen was completed in 1935, best described as a modernistic traffic and architectural piece of work. It is indisputably an area of importance for the city of Stockholm, its citizens and visitors. How has media reported the development of the New Slussen project?The analysis, and the conclusions drawn from it, will be based upon and performed with a quantitative content analysis and critical discourse analysis.
Alice Springs drivet av solenergi - En jämförelse mellan solceller och Stirlingsystem
In the middle of Australia there is a city called Alice Springs. The city has one of the highest amounts of daily sunshine hours and sun irradiation in the world. The Australian Government runs a project called Solar Cities, and Alice Springs is one of the participators. The main part of the goal with the Solar Cities project is to increase the amount of electricity generated by solar power and by doing that lower the impact on the environment. This thesis examines the possibilities for construction of a large scale solar power plant in Alice Springs. This is done to determine the potential of creating a more sustainable energy system in the city.
Pojkars och flickors brinnande intressen : En analys av 10 elevtexter ur ett genusperspektiv
The main purpose of this study is to analyze texts written by pupils during the national test in the subject Swedish for grade 9 in order to identify and illustrate how they have met the instructions for the writing task including genre. The texts have been analyzed using Palmér & Östlund-Stjärnegårdh?s (2005) model for student text analysis. This model has been supplemented by studying word and sentence length, as well as indexes for level of readability (LIX) and word variation (OVIX) in order to illustrate possible differences in a gender perspective. The results of this study are in line with previous research, as the girls? texts are longer and more descriptive, while the boys? texts are shorter and show a wider range of word variation.
Interaktiv skrivtavla i undervisning : En multimodal fallstudie av en lärares användning av interaktiv skrivtavla i läs- och skrivundervisning
The aim of the study is to investigate how a teacher uses multimodal resources with an interactive whiteboard while teaching reading and writing. The aim is also to investigate what view the teacher has on using an interactive whiteboard while teaching reading and writing. Video-recorded observations and audio-recorded interviews are the methods used to collect data. The analysis was performed from a multimodal perspective and is also inspired by interaction analysis. The result of the analysis showed that the teacher uses several multimodal sign systems in combination with those found on the interactive whiteboard.
Lantbrukares möjlighet till en investering i solceller
When the costs for a company increase it is normal to look for alternatives to lower thesecosts. One of the expenditure that farmers have is energy costs. The price for the energy mayvary because of the free market. To look at the possibilities for a farmer to invest in sunpower, to make the company less sensitive for the changes on the electrical market, isinteresting. The biggest part of the electricity that is produced in Sweden comes from a fewcompanies on the market.
Beslut om investering i alternativ energi : en studie om hur lantbrukare fattar beslut vid investering i halmpanna
Interest in alternative energies is high in Sweden today, particularly in the agricultural sector. According to the Swedish lantbruksbarometern (2009), almost all respondents consider the use of some form of alternative energy from the farm. While interest in alternative energies is large, attention to the alternative energy straw has fallen and is almost nowhere mentioned in the literature today. Three years ago, in the Lantbruksbarometern nearly 44% of the farmers would be willing to invest in straw as heating system on the farm. How do the farmers decide to invest in alternative energies? With this information a problem is presented for this paper.
