This report describes the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the heat storage that is active in a greenhouse.The computer model is used to simulate the thermal climate in a greenhouse under three periods, winter, spring and summer. It also investigates which effect a concrete wall has on the thermal climate in a greenhouse. The purpose of putting a concrete wall in the greenhouse model is to investigate the possibility to store heat during the day and then use this heat when the temperature drops during the night.The result from the simulations shows that a concrete wall levels the big difference in temperature that normally occurs under a day in a greenhouse.

AimThe aim of this essay is by using a motor skill track to see if there exists any remarkable difference in the motor skill profiles between pupils from our montessori school and the mean score in the "Nytidstest". The questions at issue we had were: How is the motor skill profile on pupils in year 2 and 3 practicing montessori pedagogy? Is the motor skill profile superior or inferior to the mean score in the "Nytidstest"? What factors, if any, concerning the montessori pedagogy affects the results of the test?MethodWe used a motor skill track consisting of 8 stations sellected from the "Nytidstest" adapted for year 3 (the original test consists of 16 stations). Pupils from year 2 and 3 in our chosen montessori school were tested in groups of 4-5 persons each. We made the tests on two occasions each lasting for 100 minutes at the time.

In system development it is today increasingly common to use a model-based system development method. These methods that are suited for Agile work with simple and quick updates and implementations of new applications in systems conform to the requirements that are becoming more important today, namely more flexible and less expensive system that still maintain high quality and safety.A company that has been working with this type of system development method for a long time is Genicore AB, which also has developed their own tools and model language in order to better model the information management systems in complex and abstract operations. Genicore AB is trying to spread their method other developers and have therefore taken the initiative to start this study. The method is evaluated and tested by two students with relatively little experience in model-based systems engineering in order to gain a new perspective on how the method functions. The method has been applied to an educational activity in order to test it in a new domain, and this led us to our research question;?What criteria are of particular relevance in the implementation of a MBSD method on on complex businesses??Through literature reviews and interviews, we formed an idea of how model-based system development works from a theoretical perspective, and then continued to the case study conducted on the educational activities at the faculty of IT at University of Gothenburg.

Syfte: Studiens syfte var att deskriptivt beskriva förskrivningar av Fysisk aktivitet på Recept (FaR®) i Primärvården i Landstinget Uppsala Län (LUL) 2009.Metod: Insamlad data från förskrivare, på 26 vårdcentraler i LUL, erhölls i form av utdrag ur journalsystemet Cosmic. Data bestod av avidentifierade recept vilka sammanställdes med hjälp av variabler i Excel. I Cosmic registreras data från receptet om patienterna (kön, ålder), ordinationen (förskrivningsorsak, träningsform, typ av aktivitet, intensitet, duration), förskrivarens profession, vårdcentral samt förekomst av ordination med hänvisning till stöd av friskvårdslots.Resultat: Under 2009 förskrevs 883 FaR ut i primärvården i LUL. Detta motsvarar totalt 0,55 % av alla de som besökt vårdcentral i primärvården med en spridning på vårdcentralnivå mellan 0,04 % till 2,45 %. Medelåldern för hela populationen är 49 år (åldersspann 18-86 år).

During my practical training I have seen what after-school offers children. Large groups of children and little staff, often results in that the children had to play freely until they go home. Few activities are offered to the children and the staff is busy looking after the children and ensures that they are not fighting.The purpose of this study is to find out how children feel about their leisure activities and if they think they are being offered a meaningful leisure. The main research questions were:How do children experience their leisure-time?Do after-school offers children a meaningful leisure and is it the children's interests and needs that govern the activities and the environment?How do the number of children in the leisure group affect the leisure time?The methods to collect data in the study are observations and interviews.

Mot bakgrunden att matematikresultaten sjunker i svensk skola är det viktigt att lärare använder metoder som bygger på evidensbaserad forskning. Denna systematiska litteraturstudie syftar till att bilda en djupare förståelse för utomhusmatematik genom att undersöka lärares och elevers attityder till metoden, samt om utomhusmatematik finner vetenskapligt stöd och kan rekommenderas som undervisningsmetod.Studiens resultat visar att både elever och lärare överlag ser positivt på utomhusmatematik då metoden bidrar till ett autentiskt lärande. Många lärares uppfattningar är att utomhusmatematik gynnar de yngre eleverna och att geometri och statistik är de delar av matematiken som är lämpligast att ta med utomhus. Utomhusmatematik motsäger kursmålen i alla länder där forskning på temat genomförts och metoden har svagt vetenskapligt stöd, då för få evidensbaserade studier på området utförts..

The essay is written at the request of Nyköping municipality park management by PatRadestedt who wanted a design proposal for one of the five courtyards at the Tessin Schoolin Nyköping. The Tessin School is located 2 miles from the center of Nyköping and the schoolhouses approximately 900 students. To make a design proposal for the courtyard that lies atthe canteen I decided from the outset that I wanted to take some of the Tessin SchoolStudents' opinions and wishes regarding their own outdoor spaces. I had a workshop witheight students from the arts program with the image orientation in which they had to drawand tell them what they wanted to do in the courtyard. The outcome of the workshop, Iused to move forward in my future work with a concept that fit into the environment, wethen apply it in my final design proposal.

Syftet med studien var att få fördjupad förståelse kring hur personal som arbetar med personer på tidig utvecklingsnivå ser på sin roll i deltagarens självbestämmande i daglig verksamhet. Studien använde kvalitativ fallstudiebaserad forskning och utgick från fokusgrupper och observationer i två separata dagliga verksamheter. Att använda två verksamheter gav möjlighet att studera beskrivningen av rollen utifrån verksamheternas olika Activity Settings. Meningstolkning kopplat till tidigare teori har använts som stöd vid analysen. Resultatet visade att verksamheterna tillskriver sin egen roll stor betydelse för deltagarens självbestämmande när deltagaren har en tydlig kommunikation.

AbstractIntroduction: Hand Arm Risk Assessment Method (HARM) is a tool to assess the risks of deve­lo­ping complaints of the arm, neck or shoulders during manual work. The method was developed in the Netherlands primarily for employers, but is also used as an aid to work environment in­spec­tors. The purpose of this study was to evaluate the HARM-method for assessment of biomecha­nical exposure of the upper limbs when performing manual tasks as well as its suitability to be used within work environment inspection. Methods: Ten labour inspectors conducted assessments of five video-recorded work tasks. Assess­ments made with HARM were compared with those made with the Assessment of Re­pe­titive Tasks (ART) tool and with ACGIH Hand Actvity Level (HAL) - both methods for assess­ment of bio­mecha­nical exposure of the upper limbs - and with the model for the assessment of re­pe­titive work in the pro­visions of the Swedish Work Environ­ment Autho­rity on ergonomics for the prevention of mus­culo­skeletal disorders, AFS 1998:1.

The purpose of this study was to gain greater knowledge of how preschool teachers and children using an experimental- and activity box in biology. To find this out, I have used the participant observation method and semi-structured interviews since my study is qualitative. The result of the work led to a greater understanding of the biologybox. It was shown that preschool teachers' involvement is very important for children and that the biologybox contained good and inspiring materials. Although educators desired that there was more material to choose from as well as the usage time of the biologybox should be longer than 3 weeks..

The contemporary angel-symbol is deeply rooted in our cultural history, with connotations and implications leading to that inner transitional space where all creative activity takes place. This essay investigates the history of the depiction of angels, visions of angels both ancient and modern, and includes psychological aspects of symbols as such. A closer look at surrounding symbols of angels will hopefully result in a greater understanding of the role of the angel-symbol within the context of visual culture, seen in the light of our own symbolic universe..

Bakgrund: Idag lever minst 150 000 personer med demens i Sverige, år 2050 beräknas antalet ha fyrdubblats. Insatserna för personer med demens ska ge dem den hjälp de behöver i det sociala samspelet och ge dem en känsla av trygghet. Att som människa bli sedd och bekräftad ökar chansen för god hälsa, och eftersom hunden är expert på att tolka kroppsspråk och subtila signaler som människor lätt missar erbjuder den ett speciellt sällskap.Syfte: Beskriva hundens roll inom demenssjukvård.Frågeställningar: Hur kan hunden användas i omvårdnaden av personer med demenssjukdom? Vilka effekter har interventioner med hund på personer med demenssjukdom?Metod: Systematisk litteraturstudie.Resultat: Det finns i huvudsak två olika sätt att använda intervention med hund inom demenssjukvård, Animal Assisted Activity (AAA) och Animal Assisted Therapy (AAT). AAA fokuserar på trivsel och social samvaro medan AAT har fokus på individuell behandling.

Forskning har visat att fysisk aktivitet ger en bättre prognos för kvinnor som drabbats av bröstcancer. Den beskrivs också ha betydelse för symtomlindring vid cytostatikarelaterade biverkningar, vilket i sin tur leder till ökad livskvalité hos dessa kvinnor. Det har även framkommit i studier att det råder brister inom sjukvården vad gäller att förmedla sådan information. Som ett första steg behövs en kartläggning av den fysiska aktiviteten hos kvinnor med bröstcancer, deras aktivitetsvanor och vilken betydelse fysisk aktivitet har för dem under pågående cytostatikabehandling. Denna studie genomfördes som en tvärsnittstudie med syftet att beskriva fysisk aktivitet hos kvinnor med bröstcancer som genomgår adjuvant cytostatikabehandling.

This Thesis aims to explore how to integrate an IT-system for facilitating anorganizations work with Continous Impprovements.This is done here by examining and analyzing the process within a handful ofcompanies who seem to have been successful with their own implementations. Thestudy is focused on the implementation of one particular system, "System C2".Simliarities and differences between the companies, and the established rule of thumbfor these kind of activities are focused upon. This to emphasis how another actormight emulate some of the apparent success.Part of the core question is found in the title, since Continous Improvement is oftenseen as a relativly low-risk activity, is it then also possible to take a low-risk slow pathto the implementation of such a system in the entire organization?.

An energy calculation model for Swedish houses   that is fast, flexible and user-friendly has been developed within the   framework of this thesis.  The model   also provides a set of actions which may be investigated in the model based   on savings and payback period. Energy use in a house depends on the technical   conditions, such as building envelope and heating systems, which outdoor   climate the house is exposed to and who lives in the house. Energy use for a   house can be divided into heating, hot water and household electricity. There   are several methods to calculate the energy use of a house. This report   summarizes the methods that may be suitable for a fast and user-friendly   calculation model.
