En studie av ett grupporganiserat lärande
The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

Health added-value food : the Swedish retail market
Diet and lifestyle are closely interrelated and believed to have a significant influence on four major public diseases - cardiovascular disease, cancer, hypertension and obesity, but also affects functional deficiencies like gluten- and lactose intolerance. Health added-value foods are thought to reduce health-related risks or delay the onset of these major diseases. Therefore, interest among scientists, researchers and the public in general has been growing remarkably over the last decade regarding these special foods.
The Swedish market seems to be a good target for health added-values food. However, as there are many risks and cost factors involved for companies to enter the market or invest in R&D, it is important to take a step back and analyze the current market situation.
Subject-Experimenter-Performed-Task i Episodic Integration View
Människor tenderar att minnas utförda uppgifter och återkalla dem bättre än när de enbart kodar samma uppgifter muntligt, även känd som enactment effekt. Syftet med den här studien var att undersöka om enactment effecten ökar under en ny inkodning som aldrig tidigare utförts inom paradigmet ? Subject-Experimenter-Performed-Task. Sammanlagt medverkade 56 personer i studien, 32 killar och 24 tjejer i åldrarna 10-18. En grupp lågstadiebarn och en grupp gymnasieungdomar testades i VT, EPT, SPT och SEPT betingningar.
Vad är en patientjournal? : En undersökning av användares mentala modeller
Allt fler svenska vårdgivare ger patienter direktåtkomst till sina patientjournaler via internet. För att göra sådana tjänster så lättanvända som möjligt är det viktigt att förstå vad användarna har för bild av vad en patientjournal är och hur den är strukturerad. I den här rapporten presenteras en undersökning av hur användare uppfattar patientjournaler. Undersökningen har omfattat intervjuer, öppen kortsortering (med inledande free-listing) och användningstest ? metoder som kompletterat varandra bra.
Marknadsundersökning av grisplättlysat för att ersätta serum i cellodling
High quality within a Lean production system begins with standardised work, which creates stable processes able to generate predictable output. If nonconformity from the standard procedures occurs, routines are needed to analyse, correct and prevent the nonconformity from occurring again. In that way, the nonconformity can be a trigger for continuous improvements toward more stable processes. In takted production lines, where the operator follows a standard sequence with tasks set to be completed within the takt time, a nonconformity leads to downtime in the operator?s sequence, and no value is added.
Utveckling av Mätmetoder för Färdmotstånd
The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.
Elevers upplevelser av extra anpassad skolidrott- en intervjustudie
The Swedish curriculum says that the education will adapt and take notice of every child?s individual condition and needs. Every child has the right to development, to feel the happiness of growing and to experience satisfaction of making progress and overcome difficulties. In every class it is often children who need adapted physical education. The earlier these children can get support and practice, the bigger the chance is that they will catch up.
Utvärdering av energieffektiviseringsåtgärder på Bokelundskolan i Växjö
The purpose with this report is to examine how the implemented energy efficiency measures on Bokelundskolan in Växjö have had impact on the energy use. The measures which have been implemented are, new ventilation system, new heating system, optimized adjustment of the heating system, new windows with U-value 1.2 and lower window height, insulation under windows and in the crawl space. The school's energy use before and after rebuilding has been calculated with the calculation program, Vip-Energy 1.5.5.Calculations of energy use for the school with windows on U-value, 0.9 and 0.7 have also been done. The replacement of windows has been studied from a cost perspective. The conclusion is that the exchange of heat and ventilation system was the biggest contributor to reduced energy use on Bokelundskolan.
??då hör inte jag hemma hos er!? : - Att ta avstånd från en religiös gemenskap
This study focuses on why people not longer want to be a part of a religious communion they have earlier been a part of. To examine this I have made seven interviews with people who have left their previous communions. Together with the methodological and theoretical discussions on discourse analysis, Richard Jenkins discussions on identity and theories concerning the post-modern society, I have made an analysis on how these people consider their previous communions and its members. They refer i.e. to the social control, the ?closed? culture and the non-questioning-culture that constitute the communions and its techniques.
Sänkt returtemperatur : Potentiell besparing i fjärrvärmesystem
Optimizing energy systems is, in Sweden, as in many other countries, of growing interest. District heating systems are no exception. In 2012, 285 out of 290 municipals in Sweden had district heating in use and the majority of these systems have a higher return temperature than that which is possible with an error-free substation of day current technology. To, when possible, lower the return temperature is a way of increasing the effectiveness of the district heating system.This study means to investigate, through simulations and calculations, how big of a reduction in production cost a lower temperature in the city of Ystad?s district heating system would correspond to.

Stadsplaneringsideal. Med den periurbana zonen i fokus - dess potential för den hållbara staden
To be able to plan for the expansion of a town, one needs a vision of the future appear-ance of the town. It is the current issues (social situation, supply and demand, political control etc.) which decide what the ideal for town planning is. This is turn is the steering factor of the physical structure of the town. Therefore, the town's structure is decided by these ideals.In this report, I will present planning ideals that have historically been, and which criticisms that have been directed towards them. With reference to these issues, I will present those guidelines and ideals we have today for planning of our towns.
Blomgren - en mönsterkollektion
This report is about the exam project; Blomgren- a collection ofpatterns. During eight weeks I have from the family Blomgren, whowas my grandfather?s family with siblings and parents, produced fivepatterns for textiles into interior and space. In addition to thefamily as an inspiration, I have taken into account of the collection?sname - as a word and the meaning of the word.
Loggbok och lärande : Elevers perspektiv och pedagogiska intentioner
The purpose of this paper is to juxtapose the theories of learning that are reflected in student?s perspectives of the learning log with that of the pedagogical intentions of the curriculum in order to examine the discrepancy between the experienced and the intentional learning objectives. The paper is divided into two sections. The first section is a literature survey on theories related to the learning log and the curriculum. The second part is constituted by three semi-structured group interviews concerning student´s views on the learning log.
