Geotermisk fjärrvärme i Gunsta

Gunsta is situated about 10 km east of Uppsala. Today there are plans to establish 1000 new households in Gunsta before year 2030. The required energy for heating houses and water would be distributed via a district heating system, which also includes 200 existing residences. The annual required energy, according to this study, would be 16.2 GWh with a maximal peak effect of 6.9 MW. To meet this need, the study suggests a system with heat pumps to upgrade the 31?C water from a 1.8 kilometre deep borehole.

Kvinnors upplevelser vid missfall och deras efterfrågade stödinsatser : En litteraturstudie

Background: Miscarriage is a common phenomenon in our society. It is reported that approximately 17 % of all pregnant women in Sweden go through a miscarriage every year. For many women miscarriage is a tumultuous life event that often has a deep emotional impact. Miscarriage is a subject that often is prohibited to talk about in our western society.

Organisering, matematiskt innehåll och feedback i specialundervisning : En kvalitativ fallstudie av några specialpedagogers matematikundervisning

SammanfattningDetta är en kvalitativ fallstudie av fem specialpedagogers arbete med specialundervisning i matematik. Syftet är att kartlägga deras arbete och uppfattningar genom att beskriva och analysera hur de organiserar sin undervisning i matematik, hur de undervisar ämnesinnehållet och hur de ger feedback till eleverna i klassrummet, samt hur de själva beskriver det de uppfattar som det specialpedagogiska inslaget i sin undervisning. För insamling av empirin har en kvalitativ metod med halvstrukturerade djupintervjuer samt observationer i form av ljudinspelningar och ostrukturerade fältanteckningar under lektioner gjorts. Ramfaktorteorier, fenomenografiska teorier, inlärningsteorier samt fallstudien, har styrt mitt sätt att bearbeta och analysera det empiriska materialet. Resultatet visar att det lärande som erbjuds eleverna av fyra av specialpedagogerna bidrar till ett ytinriktat lärande, och feedback som erbjuds bidrar till yttre motivation.

Fr?n de komplexa talens r?tter till klassrummet

This research overview examines what research says about upper secondary school students' difficulties with complex numbers. The three main areas covered are general difficulties with complex numbers, how to teach the subject, and whether the history of complex numbers can be beneficial in this teaching. A historical deep dive into the history of complex numbers is also included to further investigate this idea. The results show that upper secondary school students struggle with complex numbers in various ways. The name of the subject creates a negative connotation, as it is initially perceived by students as fictional and complicated. Furthermore, a consequence of the inherently abstract nature of complex numbers is that gaining a comprehensive understanding of them is challenging.

Förskolepedagogers uppfattningar om leken som redskap för barns språkutveckling : en observations- och intervjustudie

The value of a good reputation for organizations is increasing today as consumers and citizens become more aware of brands. If a crisis hits an organization, there is now more to lose than before concerning reputation. Therefore the organization?s communication strategies must be developed to sustain the organization?s reputation during and after a crisis.In the field of crisis communication there are two distinguished theories which concern what an organization with help from crisis communication should do to undergo a crisis without losing its reputation. These theories are image repair theory and situational crisis communication theory (SCCT).

Den fiktiva läsaren i dagstidningar : En undersökning om skapandet av fiktiva läsare i tre tidningar 1890

An enriched arena for lamb - anticipation behaviour before entering the arena, effects of skipping the anticipation phase and effects of being denied access to the arena

This study aimed to investigate whether lambs show anticipatory behaviours in a holding pen prior to entering a known arena, whether the holding pen experience prior to the arena exposure affects their play expression in the arena and whether their behaviour (in home pen) is affected if arena access is denied. Twenty pair-housed male lambs (average 14 weeks old), were exposed, in chronological order, to five treatments. Holding pen treat-ment (HP-control): Each pair was led into a holding pen (2.7 m2) and remained there for 5 minutes before returning to their home pen (6 m2). Holding pen ? arena treatment (HP-A): Each pair was led into a holding pen for 5 min and then was allowed access into the arena (22 m2, containing two hanging chains, one ball and one platform) for 15 min before re-turning to their home pen.

Perceptions of domestic solar systems : a study on non-adopter views of a new technology

The world is currently facing a huge severe challenge in handling the issue of climate change. One of the ways to lower the green house gas emissions, which is seen as one of the main contributor to the climate crisis, is to use renewable technologies such as for example photovoltaic (PV) systems. PV-systems are also suitable for so called micro production, small scale energy production facilities, since it can be placed on practically any rooftop with the right solar conditions. In Sweden the usage of PV-systems has not yet gotten any wider spreading, even though the solar radiation conditions are very similar to countries that produce a lot of solar energy, as for example Germany. The aim of this paper is to describe non-adopter perceptions of PV-systems. The study holds a qualitative approach using deep interviews for data collection.

Skolbiblioteket som socialt rum. Om skolbibliotekets placering och utformning.

The aim of this Master's thesis is to explore how the localisation and the design affect the conditions for a school-media centre. A school-media centre is in this study a place where the students seek, find and evaluate information, discuss and exchange ideas. An active place for generating knowledge. The method applied in this study is "Space Syntax Analysis", a quantitative method with visual representation of the results. In the theoretical framework, space is the voids between walls, doors and ceiling, between furniture and bookshelves.

Jämförelsestudie avseende stomsystem : Ramverk eller fackverk/balk/pelar-system

Projektet omfattade en jämförelsestudie avseende stomsystem. Studien undersökte ramverk och fackverk/balk/pelar-system och genomfördes självständigt med stöttning av Ramböll AB´s kontor i Falun. Syftet var främst att undersöka vilka skillnader det finns mellan tvåledsramar och fackverk/balk/pelar-system för lätta hallbyggnader och försöka få klarhet i varför fackverk/balk/pelar-system är det dominerande systemet i Sverige eftersom övriga Europa har tagit en annan utveckling och domineras av tvåledsramar. Studien undersöker skillnaderna mellan systemen i en hallbyggnad med förutbestämda mått i stål.Inledningsvis gjordes en litteraturstudie för att få en bredare bakgrund av systemen och en bättre förståelse om förutsättningarna för varje system. Efter litteraturstudien kunde sedan ett typhus och beräkningsunderlag för jämförelsestudien tas fram.
