Projektering av ventilationen till studio Acusticum

Arbetet handlar om Piteås nya konserthus studio Acustikum som skall byggas vid musikhögskolan. En studie är gjord på stora konsertsalen. Ett bra inomhusklimat är ej lätt att uppnå eftersom hårda ljudkrav gör det svårt att tillföra luft i tillräcklig omfattning. Det finns vissa krav avseende luftflöden, men bara för att de är uppfyllda så är det ändå inte säkert att det blir ett bra klimat. För att kunna förutse lufttemperaturen i salen så användes CFD simulering.

"Var och en sin egen lyckas smed" : En undersökning av skivbolagens framtida roll i musikindustrin

This study has the purpose of looking at the current and future position of record labels from a context involving the technological developments, while the opportunities for the artists are changing. As the actors inside them music industry find themselves in an ever changing climate where traditional supply chains are threatened by new technology, the record labels need to change the way they work in order to maintain their existence in the music industry. The study has been conducted by interviewing a number of people involved in the music industry, by using a qualitative method approach. The conclusion of the study shows that the traditional way of doing business by treating music as a product that makes revenue is gone. Instead the labels have to take on new roles formerly run by third parties in order to survive and be profitable, especially since artists can now in control of activities that used to be controlled by the record label..

Kvinnors copingstrategier vid bröstcancer - en litteraturstudie med systematisk ansats

Syftet med denna litteraturstudie var att beskriva vilka copingstrategier kvinnan använder sig av när hon har bröstcancer. Metoden som användes för denna litteraturstudie var Goodmans modell med sju steg för ett systematiskt tillvägagångssätt. Litteratursökningen utfördes i databaserna PsycInfo, Cinahl, PubMed Cochrane, SveMed+ och Medline. Oberoende av varandra har 10 artiklar kvalitetsgranskats enligt Carlsson & Eimans (2003) bedömningsmall som modifierades till den population som undersöktes. Resultatet av tio inkluderade studier visade att det fanns ett flertal olika copingstrategier som kvinnor använder sig av när de har bröstcancer.

Branddimensionering av bärverk: En analys av Eurokod 1991-1-2

Vid brandteknisk dimensionering av bärverk används bland annat Eurokoder för att bestämma de termiska och mekaniska lasterna som uppkommer till följd av en brand. Dessa är framtagna efter ett beslut av EG-kommissionen 1975 för att harmonisera marknaden för tjänster och produkter inom byggindustrin, samt bidra till mer enhetliga säkerhetsnivåer inom branschen. Reglerna är framtagna enligt den europeiska standardiseringsorganisationen CEN med hjälp av en styrgrupp med representanter från medlemsländerna. Vissa val ges dock i Eurokoden angående värden och klasser som är upp till medlemsländerna att besluta om.Detta examensarbete avser att granska regelverket EN 1991-1-2, även kallad Eurokod 1 ? del 1-2, för att undersöka dess bakgrund och avgöra om brister existerar.

New Generation Surface treatment for tools : A preliminary study

The surface finishing technique called black oxidation is currently being used on thetool holders made of low alloyed tool steel produced by Sandvik Coromant. Blackoxidation isn?t considered a sufficient technique because it doesn?t make the toolholders look like the quality products that they actually are. The reasoning behind thisis that the tool holders can show signs of corrosion after prolonged storing times orin countries with high humidity and temperature. The corrosion doesn?t decrease thetool holders performance, but the customers might believe otherwise.

This thesis aims to show the positive effects of marketing by studying whether the regulation on direct marketing to consumers of prescription drugs today prevents to consumers accurate information and better health, and how consumers relate to the possible legalization of increased marketing through controlled and information audited webpages. Methods used in this research are qualitative method, quantitative method, documents and websites studies. The thesis fulfills the purpose as it shows the potential positive effects of an expanded marketing through pre-approved websites. It also shows a demand from the consumers' side and a need for increased awareness for more empowerment over their own health.

Säsongsvis avverkning : det operativa traktvalets påverkan på den säsongsmässiga uthålligheten i ett bolagsdistrikts traktbank

Due to soft grounds in combination with seasonal variation in soil humidity, there is a lack of stands that are possible to cut during spring and autumn in some geographical regions. For Holmen Skog this sometimes means that a large proportion of the contracted private forest is cut during the winter when the ground is frozen. One consequence of this is that the proportion of winter stands in the stand bank of own forest increases while spring and autumn stands becomes a scarcity. This in combination with milder winters, especially when there is a long period of reduced bearing capacity in spring or autumn, means that the situation rapidly can become critical. The overall goal with this study was to generate basic data for decision support in the work to achieve a sustainable distribution between own forest and contracted private forest in the stand bank. The study took place at Holmen Skog, district of Umeå, during autumn 2007 and was based on interviews and an analysis of harvest planning and delivery data. The study showed that there is a problem with how the cutting is distributed between own and contracted private forest during the year and that it foremost is the proportion of winter thinning of own forest that has increased in the stand bank.

Utredning av va?rmesystem pa? ICA Kvantum Umeå

Sveriges totala energianvändning uppgick år 1970 till 457 TWh medan den idag är uppe i 600 TWh. Det visar hur kraftigt vår användning har ökat den senaste tiden och att vi nu bör göra något åt detta genom att energieffektivisera hela kedjan från produktion till användning. En undersökning som fastighetsbolaget ICA Fastighet AB genomfört visar på en genomsnittlig energianvändning bland livsmedelsbutiker på 421 kWh/m2,år. ICA Kvantum Kronoparken i Umeå har en specifik energianvändning på 658 kWh/m2,år vilket gör att butikens användning är hög och över medelvärdet.Projektets syfte är att utföra en fallstudie på ICA Kvantum Kronoparken i Umeå genom att kartlägga den totala energianvändningen utifrån utvalda användningsområden. Vidare skall olika alternativ till värmekälla undersökas för att byta ut den värmepanna som förser fastigheten med värme idag.Fastigheten har idag en total energianvändning på 2 237 MWh/år och en total uppvärmd yta på 3 400 m2.

Energikartläggning av en livsmedelsindustri : samt förslag på energieffektiviserande åtgärder

This thesis concerns an energy audit of a food industry. The company's business consists of boiling and peeling shrimps, and producing mayonnaise-based salads. This type of work involves energy-intensive processes, such as steam generation, compression of air and refrigeration of large spaces. These needs are supplied with electricity. Furthermore, the industry is a major consumer of district heating, particularly for heating the supply air in the ventilation system.

IKT som pedagogiskt verktyg : - en studie om lärares användning av IKT i undervisningen

 The purpose of this study is to investigate the attitude to and experience of information and communication technology (ICT) in teachers teaching and what motivates them. The study is qualitative and its research material is based on interviews. There are eight interviews and they where carried out at one school with a stated IT profile and at another school without a stated IT profile. The two schools are located in different municipalities, but both are secondary schools. The result shows that there are differences in attitude between the two schools. The school with a stated IT profile seems to have a more open mind of using ICT when teaching, but both schools sees the lack of availability as one of the main hindrance for using it. None of the participating teachers saw themselves as controlled to use ICT in their teaching.

Simulering av värmebehov för kombinerad kontors- och laboratoriebyggnad utan traditionellt värmesystem

In this Thesis the possibilities of designing a larger building that is very energy efficient in the sense that it would not need a conventional heating system are discussed. Solar radiation transmitted through the windows, internal heat from occupants, lamps and electric appliances inside the building and heat recovered from the ventilation system then have to be sufficient for the heating of the building. This study is of general interest since the property company, Akademiska Hus, plans to use this study as a first step in determining if this technique could be used in the future and thus be worth further investments. A building without a conventional heating system of the size investigated in this project has not yet been built.The energy needed for the heating of the building was simulated using VIP+.The conclusions from the study are that it is possible to build large buildings without any conventional heating system. This could be achieved in many different ways, for example by lowering the inside temperature or by using better windows and heat recovery system with higher efficiency.

Utvecklingen av grammatikinstruktioner och övningar i svenska läromedel för spanska : En läromedelsanalys om explicit instruktion, input, produktion och interaktivitet i undervisningsmaterial för främmandespråk

This study investigates if and how grammar instructions and exercises in Spanish textbooks have evolved during the last thirty years. More specifically it focuses on how the grammar is presented (explicit instruction) and on the nature of the exercises (input, production and interaction). The method for investigating these things is firstly an analysis of the explicit instruction, and secondly a quantitative study of the exercises. The number of textbooks analyzed in this study is four and only the chapters that focus on teaching the preterite are included in the analysis. The result shows a tendency towards direct explicit instruction and controlled production practice.

Marknadsundersökning för en fuktsensor med RFID-teknik

Fukt i byggnader är svårt att upptäcka och är ett vanligt problem i dag.Att i ett tidigt skede kunna se hur fuktigt det är kan bespara dyrakostnader. En ny produkt som företaget Sensible Solutions har tagitfram är en fuktsensor som kan placeras innanför väggar i till exempelbadrum. Fuktsensorn består av två RFID-taggar där en av taggarna äromsluten i ett fuktabsorberande material. När det fuktabsorberandematerialet drar åt sig fukt kommer den taggen bli svårare att läsa av,vilket indikerar att fukt förekommer. Avläsningen av fuktsensorn skergenom en handhållen RFID-läsare.
