Kan fysisk aktivitet förebygga Alzheimers sjukdom? En litteraturbaserad studie.

Introduction: We are facing an aging population, which means that the incidence of age related diseases, such as Alzheimer's disease, are expected to increase. In the current situation there is no cure for the disease, whereupon it is important to develop preventive strategies. Objective: To examine the association between Alzheimer's disease and physical activity. Method: A systematic literature search was done to identify the current state of knowledge from the year 2006 onwards. The reason for this limitation was that the SBU commissioned a systematic literature review in 2006, where the relationship between physical activity and Alzheimer's disease could not be determined.

Utvärdering och utformning av webbokningssystemgränssnitt

Eftersom webbokningssystem kan ge stora fördelar för feedback och valmöjligheter jämfört med övriga bokningstekniker, är detta ett sätt att boka på som allt fler människor väljer. I de webbokningssystem som existerar idag finns det dock flera brister, dels beroende på att de ser ganska olika ut beroende på vilket företag som står för dem och dels därför att inte alla möjliga funktioner utnyttjas. I detta examensarbete har det därför genom intervjuer och enkäter undersökts hur användarna vill att ett webbokningssystem ska se ut och vilka funktioner som ska finnas. De slutsatser som har arbetats fram är antalet sidor ett webbokningssystem bör vara uppbyggt av samt om och hur olika funktioner bör användas i ett webbokningssystem, och hur dessa i så fall ska se ut. De resultat som framtagits i arbetet ger goda riktlinjer om hur ett webbokningssystem bör se ut och kan användas som en guide för uppbyggnaden av webbokningssystem.

Uppföljning och analys av Stockholms stads solcellsanläggningar

During 2007 the City of Stockholm installed five grid connected photovoltaic systems. The aim of this master thesis is to quantify the amount of produced energy and recommend routines to collect and analyse production data, to make production data accessible by the public and to gain experience for future installations.The total amount of produced energy until March 2009 is 227 000 kWh, with an annual rate of 150 000 kWh. The expected annual rate was 148 000 kWh.All system owners are positive about their plants and see economical benefits in scaling up such systems.The installations need very little attendance and maintenance, however it is recommended that an alarm function is installed for automatic feedback in case of a system failure. All future systems should be inspected during full operation to determine if the actual capacity is matching the installed capacity..

Åtgärdsförslag och känslighetsanalys vid energieffektivisering ur ett fuktsäkert perspektiv : En fallstudie på timmerhuset Sofiedals herrgård

This thesis investigated the possibilities to resume cultivation of an old manor house built of timber and what this would mean from an energy and moisture perspective. The building in this case study is named Sofiedals mansion and was built in 1858 in Valbo 11 kilometers west of Gävle.The structure of the house was documented and used as a starting-point for carrying out calculations focused on energy and moisture aspects. With the help of a number of computer programs and a conducted air tightness test, the buildings energy consumption were calculated and compared with the current building regulations.In addition, the building was analyzed considering energy retrofitting and what it meant for moisture problems. The energy retrofitting consisted of additional insulation, decreasing the buildings permeability through air sealing; window and door replacements. When a building is equipped with natural ventilation it is difficult to know its precise performance and how an energy retrofitting affects it.

Att tillgängliggöra kvalitetskontrollerade Internetresurser: en studie av två ämnesportaler och två samverkansprojekt

The purpose of this masters thesis is to study two subject gate-ways within the field of Swedish higher education and academic research, concerning structuring and selection of Internet resources to facilitate information retrieval for their target groups, and also to study two co-operation projects in the same field, one national and one European, to see how the co-operation is being carried through and how the gateways in the projects can serve from a wider perspective. The gateways, AGORA and NOVAGate, are being studied mainly by their Web sites and two e-mail interviews with persons responsible for the gateways. Facts about the national project are principally based on an interview with BIBSAM. The European Renardus is being studied out of articles and information on the Web site. From the results of the study it is being clear that the purpose of the gateways is to make a quality-selection of information accessible via the Internet and thereby facilitate for their target groups to find usable information.

Utökade tillämpningsmöjligheter för turbinlösning i våtpartiet hos tissuemaskiner : Konceptförslag som möjliggör tillämpning av turbinlösning för maskiner vars banbredd är bredare än 2,9 meter

AbstractThis thesis is the final part of the Innovation and Design Engineering Programme (180 ECTS credits)at the Faculty of Health, Nature and Engineering Science at Karlstad University. The extent of thisthesis is 22.5 ECTS credits and has been performed independently by Hannes Jernberg during thespring of 2013. Metso Paper Karlstad AB is the task maker of this project, and Arvid Johansson is thecompany Representative. Metso Paper Karlstad AB is one of the world leading developer andmanufacturer of tissue paper machines.In the current situation, the company has developed and patented a power management systembased on a Cross Flow Turbine. The current construction is limited to a paper width of 2.9 meters.The company wants to take advantage of all the opportunities provided by the patents, to develop aturbine solution paper machine with a paper width that is wider than 5.5 meters, and give the abilityto manufacture paper for lower energy consumption which is an important part of the production asit is very energy intensive.Problems arise with the increasing length of the turbine, ultimately resulting in that the deflectionbecomes too big and that the momentums, due to the increased torque the turbine blades breaks.By applying the design process, this work has resulted in a number of potential solutions to theproblem.

Från kraftvärme till energikombinat : En fallstudie av kraftvärmeverket i Sala

In 1997, the Swedish parliament adopted a decision on Vision Zero (nollvision) in the road and transport system. Vision Zero means that no one should be killed or seriously injured in traffic accidents in the road transport system (Prop. 2003/04: 160). For the Transport Administration in Sweden (Trafikverket), this means increased demands on security and signage at road work sites around the country. This in turn means increased demands on the contractors that carry out road work for the Transport Administration.

Shareadox : -The paradox of service quality assurance in Sharing Economy businesses

The purpose of the Sharing Economy is to exploit unused resources between people, as an alternative to buying new and owning themselves (Gansky, 2010). Gansky (2010) argues that a major reason why the Sharing Economy has grown in recent times is, besides from the recession and people?s increased environmental awareness, the urbanization which has made people move closer to each other and in to the big cities. This in addition to an increased use of GPS technology in smartphones enables people to be constantly connected to an ever-changing network. People now share and exchange services and products from each other.

Ett folkbibliotek och dess användare: användares uppfattningar av service relaterade till verksamhetsintentioner

The aim of this MA thesis is to examine how users regard and receive the services offered by a specific public library. We also examine what the conception of service means to the users and how they perceive this service being offered by the library. We look upon if and to what extent the service conception depends on contact with the library staff. The methods used are qualitative interviews and analyses of documents directing the library activities. The public library we have examined in this respect is the public library of Västerås.

Närvaro trots frånvaro :  En studie om en projektbloggs möjliggörande av gränsöverskridande samarbeten

Denna forskningsrapport undersöker hur nya teknologier kan verka som stöd för visuellt informationsutbyte och koordination för kreativa arbeten på distans. Arbetsgruppen genomförde denna undersökning för att kunna utbyta prototyper och annat visuellt material på regelbunden basis med en beställare av ett projekt som har sitt säte i New York. Projektet använde sig av en så kallad projektblogg som kanal för att förmedla utfört arbete samt för att föra en diskussion och ge feedback på det. Eftersom detta projekt skulle genomföras inom ramen för detta examensarbete valde arbetsgruppen att även undersöka hur examensarbetet skulle kunna koordineras genom projektbloggen. Dessa två undersökningar skedde genom en fallstudie under 8 av examensarbetets totala 10 veckor.
