Frånluftsåtervinning i ett äldre flerfamiljehus : Hovgården - Borlänge
I detta examensarbete undersöktes möjligheten att installera värmeåtervinningssystem för ett flerfamiljehus i Hovgården som ligger en bit utanför Borlänge. I rapporten redovisas två olika sätt för energibesparingar som är aktuella för att ersätta borttagning av oljepannan som används i huset i dag. En rad svårigheter dök upp under undersökningen för installation av nytt värmesystem. Lämpliga lösningar kunde hittas efter mycket analys. Syftet med rapporten var att undersöka möjligheten och lönsamheten för installation av något av följande system; FVP eller VBX-modul som kan återvinna värme ur frånluften.
Romer i samhällsdebatten : En kvalitativ studie om framställningen av romer i debattartiklar
The purpose of this study is to investigate the medial portrayal of Romani people in the newspaper Dagens Nyheter from 2013 and 2014. In the theoretical chapter the concepts of new racism is used to speak of what is considered racist in the Swedish society today. Other concepts that are used are type and stereotype which are used to explain how our context is depending on distinctions to understand what surrounds us. Concepts such as myths and binary-oppositions are other theories that are used in this study. Six debate articles have been selected to investigate how the Romani people are represented.
INDUSTRIELLT EKOLOGISK STADSODLING : EN KVALITATIV STUDIE SOM UNDERLAG FÖR EN STADSODLINGSREVOLUTION I STOCKHOLM
Rooted in Industrial Ecology (IE) theory, this report evaluates how urban agricultural concepts and techniques, can contribute to improved ecological sustainability within the inner city boundaries of Stockholm. An overarching literary study as well as an interview was carried out, resulting in a qualitative analysis followed by suggestions for practical implementations. A substantial convergence was found between the eco-restructuring objectives of IE and the principal motives for urban agriculture. Consequently, eco-restructuring objectives are found in varying degrees in the presented urban agricultural techniques. Industrial symbioses, permaculture and combinations of urban agricultural techniques are tools which are capable of corresponding adequately to the diversity of urban settings.
Det är mig det handlar om ? en intervjustudie om patienters upplevelse av möjlighet till delaktighet
Background: In Sweden it is a legal right for patients to have the possibility to participate in their own care. Several studies highlight the importance of a good relationship, good communication and good cooperation in order to increase a sense of security and thus the possibility of participation. One way to increase patients' ability to influence and participate can be to adapt person-centered care. This moves the focus from the patient's illness to the patient and his/her resources. Aim: The aim of this study is to describe patients' experiences of the possibility to actively participate in decisions regarding its care and treatment at surgical wards.
Geoenergilösning för DN-huset
In this thesis proposals for different designs of a borehole thermal energy storage (BTES) have been developed for the building DN-huset in Stockholm, Sweden. To build a BTES results in savings in energy costs by approximately 44 %, i.e. 2 million Swedish crowns annually. Furthermore, a BTES would reduce the annual environmental impact with roughly 75-157 tonnes of CO2 equivalents per year, depending on how the electricity consumption?s environmental impact is estimated.
Behöver tillväxten en stad? Om Dublin som politisk arena, aktör och tillväxtmotor
This thesis intends to examine the role of the city, Dublin, in the Irish economic growth during the 1990s. It is a case study where Dublin is compared with current theories on post modern cities as growth machines and increasingly prominent actors in the global context. The study has an interdisciplinary approach but focuses on political science issues such as power distribution, global-local governance and local political organisation. It is a theory driven study that also intends to add aspects to the understanding of the cities of our time. I argue that Dublin has faced a lot of changes during the last decades in accordance with the post modern city.
Pojkar är starka, flickor är rosa. : En studie av leksaksreklam riktad till barn.
Syftet med denna uppsats är att kritiskt granska leksaksreklam riktad till barn. Genom att använda oss av reklamklipp från det sociala mediet YouTube vill vi undersöka hur manligt respektive kvinnligt samt heteronormativitet konstrueras i dessa. För att finna mönster som vi kan koppla till vårt syfte tittar vi ur ett genusperspektiv genom textanalys närmare på reklamklippen.Genom vår analys fann vi att leksaksreklam riktad till barn är påtaglig könsstereotyp och skapar förväntningar på barn hur de ska se ut samt vilka egenskaper de förväntas inneha. Vi fann också att reklamklippen reproducerar heterosexualiteten som den hegemoniska sexualiteten. Detta gör att heteronormativiteten blir stark i reklamklipen då samtliga reklamklipp riktade till flickor vi tittat på är byggda på en parrelation mellan en man och en kvinna.Nyckelord: Genus, heteronormativitet, maskulinitet, könsroller, leksaker, den inre och yttre sfären, arbetsdelningen, passiv och aktiv, rosa..
Påverkan av skogsbrand på litiska arkeologiska fynd ? experimentell simulering av brand
This is a paper about the effects from smoldering fire on lithic objects from an archaeological view.
The introduction gives the background to this paper, a short orientation to forest wildfires and why the work is limited to: flint, quartz, quartzite and slate. Material and methods describes the stone materials and the setup that was used in the temperature logged tests with three replications for each type of material. The fuel in the burnings was peat on a bottom of sand. Flint showed a more drastic effect from heat compared with the other materials. Slate seems to have greater tendencies to change to darker colour and luster at lower temperatures than the other materials.
Vem bestämmer över kvaliteten? : Bibliotekariers privata och professionella syn på kvalitativ skönlitteratur
With an increased empowerment of the users, and a dependence on outside critics, one wonders what kind of role the librarians have in a context where qualitative literature is discussed. The aim of this study is to examine the relationship between librarians private and professional views on qualitative fiction, in order to be able to discuss their role as quality intermediaries in a user oriented context.The method used, is the qualitative, semistructured interview. This author interviewed seven librarians from three different libraries in Sweden. The theoretical emphasis partly relies on the ten words of qualitative value that Inger Elam and Bengt Brülde discusses in their respective texts, partly on David Garvins quality assessment theory, which defines several quality categories divided between an absolute and a relative quality view.Through the comparison between the private and the professional quality view, examined with the two theoretical approaches, the analysis of the interview material shows that there lies a complexity in the librarians professional role. On the one hand, they are dependent of both the users and the critics judgements about the qualitative aspect in the work with purchasing new literature to the library.
?Läsandets cirkel? i förskolan - en studie av läsmiljön utifrån Aidan Chambers litteraturpedagogiska idéer
The aim with this thesis is to highlight components regarding small children?s reading environment in preschool and see how these affect their meeting with literature. The study is based on J. A. Appleyard?s theory on man?s development as a reader.
Bilden av Östasien : Hur östasien framställs i gymnasiets läroböcker i historia
Textbooks are a very influential medium considering the fact that they often introduce students to information they have never read or heard about before, and as such they become very important in forming students? opinions on different matters. In this study I have taken a closer look at five textbooks in history that are currently being used in the Swedish upper secondary school. My aim has been to find out how East Asia is pictured and also how much space East Asian history is given in these textbooks with the postcolonial theory as theoretical basis. My study shows that East Asia is given very little space compared to Europe in these books, with an average of less than a twentieth of the number of pages that deal with European history.
Styr- och beräkningsprogram för kalibrering av värmestrålningsmätare
Då det köptes in ny utrustning för kalibrering av värmestrålningsmätare till SP, Brandteknik, fanns det ett önskemål om att effektivisera proceduren vid kalibreringen. Vid kalibrering med den befintliga hård- och mjukvaran finns många manuella moment som skulle kunna reduceras.I detta projekt har ett styrprogram utvecklats i programmeringsspråket LabVIEW. Programmet använder ett seriellt kommunikationsprotokoll för att styra den kontroller som reglerar temperaturen i kalibreringsugnen. Programmet ställer in de temperaturnivåer som ska ingå i kalibreringen, upp till tio stycken, och kontrollerar när temperaturen har stabiliserat sig. När den gjort det tas ett antal mätpunkter ut och sparas till en resultatfil.
EAS-tagg med fuktsensor : Design och utvärdering av EAS-alarmteknologi för fuktdetektering
Electronic article surveillance (EAS) is widely used in shops and libraries together with an RF-tag attached to the goods or books in order to prevent shoplifting. By implementing the addition of a moisture sensor to the RF-tag, other functions become possible, including the ability to use as an alarm with regards to frozen goods, which have been shipped but which have melted and have, subsequently, refrozen. In- relation to care for the elderly, one time-consuming step involves checking whether there is the necessity for a change of diaper and this can, instead, be based on an RF-tag with an EAS-system alarm. A preliminary investigation was made using the moisture sensors, which involved how the resistance changes when liquid and/or heat is applied. A simulation of the LCCR circuit (RF-tag with the sensor) was conducted in order to determine how the resonance frequency changes for different resistances levels.
Energiåtervinning från gjuteriprocess till fastighet, undersökning för ökat utnyttjande av spillvärme
This diploma work on D-level is made in cooperation with Varnäsföretagen AB in Eskilstuna. The company performs contract manufactured aluminium goods. This work is a continuation on earlier diploma work in Varnäsföretagen AB. Even if the industry process consumes much energy for melting the aluminium goods, they consume a great amount of oil to warm up the building. The purpose of this work is to examine some places in the building and the process to see how much energy it is possible to recycles to the heating system and reduce the costs for heating.
Mottagandet av nyanlända elever i skolan : Hur gör lärarna på en skola för att tillgodose nyanlända elevers behov
The purpose of the study is to see how four teachers at a school look at the reception and approaching of newly arrived pupils.How do the interviewed teachers describe the school´s reception of newly arrived pupils? How do teachers in preparatory and regular class see at the selected school's reception and treatment of newly arrived pupils?To get answers to my purpose, I have done an ethnographic study called field study and I am using qualitative interviews, and one passive observation. To arrive at a result of my study, I have processed collected data from interviews and observations and coupled the collected material to the theories and previous research. I have in my study used both pedagogical and sociological theories.The results of my study show that it would be difficult for newly arrived students to be placed directly into the ordinary class, the results also show that newly arrived students receive a safe and stimulating start to their school and class preparation. However, there are shortcomings and resistance of the trajectories leading to entry of the preparatory class of ordinary class, but when newly arrived students have started in an ordinary class, students receive a stimulating teaching.
