Energieffektiviserande åtgärderpå Robertsfors VA-nät : En förstudie av vilka energieffektiviserande åtgärdersom kan göras på pumpstationer och reningsverk
The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.
Det var tydligt att hon ville : Genus och könsmaktsordning i våldtäktsrapportering
Gruppolarisering innebär att bl.a. social jämförelse leder till att isolerade grupper med likasinnade genererar mer extrema åsikter. Gruppolarisering på internet kan vara ett oroväckande fenomen för den deliberativa demokratin. Istället för att människor med konkurrerande ståndpunkter utbyter idéer och tankar med varandra samlas de i isolerade diskussionsforum på internet där social jämförelse i värsta fall kan utmynna i hattal och terrorism. Med netnografisk metod studeras här politiska diskussioner online i två olika typer av forum, ett politiskt och ett icke politiskt.
Bestämning av lägsta luminans för utrymningsskyltar
This report is based upon an experimental study of exit sign luminescence in different environments. The purpose is to evaluate the lowest luminescence of an exit sign, based upon Swedish regulations. Scientific experiments have been conducted in a controlled environment, where exit sign luminescence was graded by an evaluation group. The results of these have been verified by similar experiments that took place in two department stores.

Fast or furious : Högfrekvenshandelns påverkan på privata aktiesparare
Bakgrund: Diskussionerna och studierna kring vegankost till barn är många och med spridda åsikter och resultat. I folkmun dominerar ofta de negativa åsikterna där riskerna för brister i kosten står i fokus. Många studier visar dock att om de vanligaste fällorna undviks växer och utvecklas barn som äter vegankost normalt. Idag hamnar debatten ofta kring riskerna med att ge barn vegankost, medan debatten kring den felbalanserade blandkostens baksidor lätt glöms bort. Enligt den senaste nationella koststudien på barn i Sverige (2003), ses generellt sett en tillfredställande fördelning av protein, fett och kolhydrater i kosten hos barn, medan typen av fett och kolhydrater är av dålig kvalitet.Syfte: Syftet med studien var att undersöka näringsintag, livsmedelsval och måltidsmönster bland barn som äter vegankost och barn som äter blandkost, samt att undersöka hur näringsintaget stämmer överens med Livsmedelsverkets rekommendationer för målgruppen.Metod: En kvantitativ metod användes där en skattad kostregistrering på totalt tolv barn genomfördes under tre valfria dagar, där hälften åt vegankost och den andra hälften blandkost.Resultat: Barnen som åt vegankost åt mer frukt och grönt, fibrer samt hade ett högre energiintag.

Inventering av bergborrade brunnar för dricksvatten i område med risk för salt grundvatten : en utredning av grundvattensituationen i Vreta-Ytternäs i Uppsala kommun
The city of Uppsala and its surroundings are a very expansive area. A prerequisite for a sustainable development of the area is well-functioning supply of drinking water. In Uppsala municipality, the Uppsala esker and Vattholma esker are the groundwater storages for drinking water. Besides the eskers, other sources of qualitative groundwater in the Uppsala municipality are relatively poor and more than half of the area consists of ground conditions with a risk of saline groundwater. The neighbourhood of Vreta-Ytternäs is situated 10 km south of Uppsala, in the area with risk of saline groundwater but outside the municipal water supply.
Liv och rörelse på nya Kungsgatan : Ett arbete om framkomligheten på Kungsgatan i Eskilstuna
This report is about how accessibility in Eskilstuna's central trade street Kungsgatan can be improved, based on my background as spatial configuration designer, and by Eskilstuna's residents' opinions. In this report I explain what methods I have used, and how I attained my results. The goal of this project was to create ideal accessibility in the central part of Kungsgatan in Eskilstuna. Since Fristadstorget was rebuilt, and since the city is growing in terms of housing and residents, accessibility will in the near future be even more limited for visitors than it is today. My design proposal is designed based on street conditions, residents' opinions and Eskilstuna's existing ideas..
Spela för nöje eller spela för kunskap? : Lärares uppfattningar av IT-baserade matematikspel och dess konsekvenser på elevers kunskapsutveckling
Sveriges Radio stores their data in large archives which makes it hard to retrieve specific information. The sheer size of the archives makes retrieving information about a specific event difficult and causes a big problem. To solve this problem a more consistent use of metadata is needed. This resulted in an investigation about metadata and keyword genera-tion.The appointed task was to automatically generate keywords from transcribed radio shows. This included an investigation of which systems and algorithms that can be used to generate keywords, based on previous works.
Musikmarknadskommunikation 2.0 : En studie av hur svenska independentbolag i musikbranschen kommunicerar med sinmarknad via sociala nätverk på internet.
This essay has a purpose of looking at Swedish independent labels in the music industry and how they communicate with their market through social networks on the internet. There have not been much research about this in the past and we hope to contribute with knowledge to the area. In mind we had the changing music industry, an evolution of the internet and viral marketing communication.To answer our research question we decided to conduct three interviews with people who worked at independent labels and had market communication as their area ofresponsibility. The three independent labels in our study were based in Sweden, except for one that is based in London, England as well as Stockholm, Sweden. We selected the independent labels based on their tendency to work with marketing communication in the social networks on the internet.
"'Jag tycker såhär och då är det såhär.' Det är inte så." : En kvalitativ intervjustudie om lärares interaktionsstrategier i bemötandet av rasistiska, avvikande och kontroversiella uppfattningar
The purpose of this study is to investigate how six students at a Secondary School describes interaction patterns among teachers when students express in a way that the teacher perceives as racist and/or xenophobic, by presenting a qualitative interview study. The interviews were analyzed by two opposing models of value education: the traditional and the constructive model.The results show that students divide teachers in different categories based on five qualities: 1) they listening, 2) they accept students' opinions, 3) they allow discussion, 4) they are knowledgeable and 5) they can express their own opinions.These qualities are included in the value pedagogical model for deliberative conversations, whose strategies for interaction aim to create an understanding of different rules and values, thereby creating skills of rules by using a democratic approach. In contrast to this model, the rule-based moral education, in which the teacher uses his authority and refers to rules without giving an explanation for why they occurred, as strategies. .
Immunokastrering av hangrisar :
Active immunization against gonadotropin-releasing hormone (GnRH) is an alternative to surgical castration of male pigs to avoid boar taint.
