Datawas collected by questionnaries, which included questions on perceived stress and energylevels, demand, control and social support at school.

SOLPANELERS MÖJLIGHETER, EN AKTUELL RAPPORT FÖR MONTAGE PÅ FASTIGHETEN KORNHILL

This thesis deals with the possibilities of installing solar panels on a property, the building is owned by Kornhillschurch and called Kornhill. The owners of the property wanted to learn more about potentials for installation of solar panels on the property, therefore we described different types of solar cells and solar cells essential function to generate electricity in the report. Different factors that are limiting the generated energy are mentioned.An investigation of the property?s potential has been made in order to consider different designs. When sites that were considered suitable for solar cells were selected, different design options were made, one for each site.

Dammsugare att motivera till dammsugning

How can a vacuum cleaner motivate you to use it? From a sustainability perspective,the author asked the question of how such a solution would looklike? These where issues that the project tackled and devised solutions for. Theproject wanted to explore the physical modeling and a large part of the finalresult consisted of a full scale model. The project found that the problem ofvacuuming largely consisted of the problem of storage the product. The projectfound that the motivation for the job, therefore, could be resolved by a betterdesigned vacuum cleaner with a built-in hose, folding handles, which couldbe stored integrated within the vacuum cleaner.

Sensory studies of an energy dense drink for elderly people

The average length of life is increasing in the western world, hence the older population is growing. A common health problem among the elderly is malnutrition. Malnutrition causes decreased body strength and is associated with an amplified risk of infections, depression, fractures and increased mortality. The health care system is therefore faced with the challenge to prevent malnutrition among the growing population of elderly. This could be done by providing nutritious foods developed to meet the specific needs of elderly. The overall objective of this project was to test a healthy energy dense drink based on oats targeted for the elderly consumers as a strategy to prevent malnutrition among elderly.

Radon i betongkonstruktioner : - Kan det undvikas?

The following article consists of two parts; one part is about house construction and the other is a specialization about radon. The house construction part describes how to project a house from start. It contains the conformation of the house, the installations needed, calculations considering the strength of the construction, energy calculation and what materials were chosen. Calculations considering the costs of building and operate the house has been carried out. The result showed that the house would cost approximately two million Swedish kroner to build and thirteen thousand kronor a year to operate.

Att förebygga och undvika fuktskador i byggnader

Efforts to achieve a moisture proof construction process have proved to be considerably complicated, despite the knowledge and awareness that now exists within the moisture field. Materials, documents, templates and checklists are designed to be accessed but are not used anyway. This may be because such effort has not been prioritized and properly requirements have not existed from the commissioner of a building.This report illustrates how the commissioner of a building project can achieve a moisture proof building process by increasing knowledge, moisture proof planning, and implementation of security moisture routines. Proposals are given on how the commissioner of a building project can work to consistently bring a moisture proof building process in all stages. The difficulty with regular moisture proof efforts, the authors believe is mainly due to the following points:      Many different design solutions.      Lack of experience feedback.      Lack of communication.      Financial incentives.      Attitudes.The interviews in the report have conducted with the help of a qualitative analysis, while the survey has been done using a quantitative analytical method.

Posthuset blir hotell En studie av Centralposthuset i Göteborg och dess omvandling

This essay in Art History treats the former Central Post Office in Gothenburg, Sweden, and its recent transformation into a luxury hotel. The magnificent original building in neo-classical style, inaugurated in 1925, has been supplemented by a twelve stories high tower in postmodern style containing hotel rooms and suites, creating a complex architecture. The approach of this essay is that of ?lived architecture?, that is, how people experience and act in relation to the building. It is argued that the history of the building is rewritten in the marketing of the hotel and the management?s concept of creating a comfortable ?mini-world?for its guests.

Ström- och temperaturkontroll

Storing kinetic energy in a flywheel allows for more efficient driving of electricvehicles. Research in this area is in progress at Uppsala University, where a flywheelwith magnetic bearings encased in a vacuum chamber is being constructed. To makethis possible methods for measuring the current through the electromagnets in thebearings and temperatures in the flywheel need to be developed. This has been thepurpose of this report. The current measurement resulted in a resistive method, andthe implementation of eight measurement circuits in the system.

En kvalitetsanalys av EU:s direktiv om förnybar energi

There's no doubt today that mankind has contributed to the changing climate byher use of fossil fuels. This must change in the nearby future. The Europeanleaders are expressing concern that renewable energy sources are not beingused to their full potential. The 2001/77/EC Directive on Electricity Productionfrom Renewable Energy Sources was accepted in 2001 to encourage thedevelopment of energy production from renewable sources, which isconsidered a step towards the fulfillment of the goal of the Union, that 12% ofthe gross energy consumption should come from renewable energy sources bythe year 2010.The objective of this thesis is to illuminate the common legislation of the EUregarding renewable energy with regard to goal fulfillment, judicial quality,conflicts with other goals of the EU and other faults. The objective is reachedby a hermeneutic study in which interpretation of written text is the mainmethod.

Tillbyggnad, Nationalmuseum

The project description is to draw an extension or annex to the existing Nationalmuseum building from 1866.The annex is designed to complement Nationalmusems activities and contain internal and public functions. Artentering the building must not be crossed by public visitors. Art and staff must be able to seamlessly move betweenthe extension and the main building. The new building includes a public study room for scholars working withthe collection of art on paper, workshops, conservation studios, art spaces and warehouses. Additionally, theannex is designed to host a large number of office spaces.With the renovation of Nationalmuseum they intend to open up the today built in south atrium.

Vägen till produktionsanpassade arbetsinstruktioner

The purpose of this thesis was to investigate the need of working instructions in Derome Träteknik ?s industrial house-building factories. Furthermore we wanted to determine an appropriate way for developing working instructions adapted to the conditions in a certain production environment. In the construction industry today prefabricated building elements are frequently used. With this come repetitive work tasks that need to be carefully planned.

Hydraulisk och termisk grundvattenmodellering av ett geoenergilager i Stockholmsåsen

Geothermal energy can be extracted from an aquifer, where the groundwater is used as heatexchange medium while heat and cold are stored in the surrounding material in the aquiferand to some extent in the groundwater. Application of aquifer storage for the use ofgeothermal energy is mainly used in large scale facilities and is limited to sites with suitableaquifers in the form of ridges, sandstone and limestone aquifers.Löwenströmska hospital in the municipality of Upplands Väsby, north of Stockholm, islocated nearby the northern part of the Stockholm esker. This means that it can be profitableand environmentally beneficial for the hospital to examine the possibilities of aquifer storagein the esker material next to its property.The purpose of this master thesis has been to investigate if geothermal energy storage with aseasonal storage of heat and cold can be applied within Löwenströmska hospital?s propertyarea using groundwater modeling. A hydraulic groundwater model was constructed inMODFLOW based on a simplified conceptual model of the groundwater system.

Bluetooth Low Energy som trådlös standard för hemautomation

Allmänheten har en stor efterfrågan av produkter inom området för hemautomation. Den senaste bluetoothstandarden Bluetooth Low Energy skapar nya möjligheter för intressanta produkter som underlättar vardagen. Lösningar som IR och Wi-Fi ger inte de förutsättningar som krävs för att på ett energisnålt och praktiskt sätt erbjuda sådana produkter, något som Bluetooth Low Energy gör. I denna rapport diskuteras standarden i syfte att redogöra för hur den kan användas för att automatisera ett hem.För detta examensarbete implementerades en strömbrytarprototyp och en iOS-applikation, vilka användes för att unders öka och påvisa ett koncept för hur tekniken kan tillämpas för hemautomation. Resultaten visar att teknikens räckvidd är dess främsta begränsning.

The effect of new raw materials on pellet prices

As demand for renewable energy is increasing rapidly, the market for biomass pellets is expected to continue to grow in the near future. Most of the new raw materials that are discussed for pellet production have one thing in common; the production costs will increase compared to using traditional raw materials such as sawdust and planer shavings. The aim of this thesis is to investigate to what degree increased use of new raw materials for pellet production will affect the general pellet prices in Sweden and to survey what plans Swedish pellet producers have concerning new raw materials. To investigate the raw material situation of the Swedish pellet producers an industry survey was performed. Literature studies were also made on previous research in the subject field. Calculations of the production costs for pellets were done for the raw materials sawdust, wet sawmill chips and energy wood respectively. New raw materials are already used by the large-scale pellet producers in Sweden.

Implementera BIM i produktionen : Vilka produktionsparamterar krävs i en BIM-modell för att produktionsledare ska kunna tillämpa BIM som verktyg till sina arbetsuppgifter?

Detta examensarbete syftar till att exemplifiera vilka informationsparametrar som är nödvändiga för att Building Information Management på ett bättre sätt ska kunna implementeras i produktionsfasen. För att uppnå detta mål har vi analyserat utvecklingen och nyttjandet av Building Information Management genom tre olika datainsamlingsmetoder; litteraturstudie, observationer och intervjuer.  I detta examensarbete har vi fördjupat oss i för- och nackdelar samt hur Skanska Sverige AB kan tillämpa Building Information Management som hjälpmedel i arbetsberedningar. Denna fördjupning har lett till att vi kan analysera vilka produktionsanpassade informationsparametrar som en produktionsledare behöver i sin tjänsteroll för att dra nytta av Building Information Management.Vi anser att användandet av en BIM-modell kompletterar produktionsledarens ledaregenskaper, vilket gör det lättare för denne att nå fram med informationen till yrkesarbetarna, då visualiseringen underlättar förståelsen inför aktiviteten. I denna rapport kan läsaren ta del av de slutsatser vi kommit fram till..
