The population of seatrout and salmon are threatened by over-fishing in the sea and loss of spawning and growing habitats caused by logging activities in many swedish rivers. The knowledge of the spawning migration and the habitat use of the seatrouts and salmon are limited. This study analyse the upstream spawning migration of Atlantic salmon and sea-running brown trouts from the lower part of the rivers to their spawning sites in the rivers Vindelälven and Piteälven. A knowledge about the distribution of spawning sites in the rivers will help these fish population in future restoration programs. In the fishladder at Norrfors in the river Umeälven were 29 sea trout and 20 salmon radio tagged and subsequently released and followed during their spawning migration upstream Vindelälven. They were tracked on their position in the river once a week.

Abstract Härstedt, J & Nilsson, L (2011) Barns lek i inomhus- och utomhusmiljö (How children play in indoor and outdoor environment) Malmö: Lärarutbildningen, Malmö högskola. Syftet är att undersöka om leken varierar inomhus och utomhus på en förskola och i så fall hur samt vad rummet och dess miljö har för betydelse för barnens lek. De metoder vi valde var videoobservationer av barnen och intervjuer med förskollärare på en förskola. Undersökningsgruppen bestod av fyra förskollärare samt fem pojkar och fem flickor i åldern fem år. Vi har studerat tidigare forskning om lek. Vi har tittat närmre på Knutsdotter Olofssons och Pramling Samuelssons teorier om leken för att få en fördjupad kunskap om begrepp som inomhuslek och utomhuslek samt miljöernas påverkan på leken. Resultatet visade att skillnaden blev annorlunda mellan inomhus- och utomhuslek.

The use and attention given to the certification system ?Miljöbyggnad? has increasedin recent years. The system is completely Swedish and was initiated in 2005 by theBygga-Bo-Dialogen. Miljöbyggnad aims to create a healthy indoor environment, reduceenergy consumption and discourage the use of hazardous chemical substances. Thegrades that can be obtained are Classified, Brons, Silver and finally Gold.The work has been to examine three different models and conclude how the designof the models affect the grades in the certification system Miljöbyggnad.

Syftet med uppsatsen var att ta reda på hur det går att använda ögonrörelseteknik för att få ett objektivt komplement till subjektiva bedömningar vid användbarhetsutvärderingar. Det gjordes en användbarhetsutvärdering av systemet Skeldar, som är en markstation för att styra en förarlös helikopter. Testpersonerna fick sätta sig in i scenariot att göra en testflygning av en färdiginställd rutt som bevakar Linköping under en högriskmatch i ishockey. Efter testet fick testpersonerna göra tänka-högt-protokoll med sina ögonrörelser som ett hjälpmedel. Resultaten som kom fram var att testpersonerna tittar mer på kameravyn för att lokalisera domkyrkan än på kartvyn och att det inte finns någon signifikant skillnad i fixeringstid eller antalet fixeringspunkter mellan hastighets- och höjdmätaren.

Background: Hepatitis E (HEV) is a small, non-enveloped virus that belongs to the viral genus Hepevirus. HEV is a positive sense single-stranded RNA virus and there is insufficient information regarding its replication. This is mainly because the virus has low capacity to grow in normally used cell cultures. Many specific strand assay detection studies have been done in order to understand more about HEV replication. Unfortunately, these assays have the disadvantage of giving false positive results.Aim: The aim of this project was to improve the positive strand assay to increase specificity and eliminate false positivity which is due to high sensitivity of the polymerase chain reaction (PCR).

Reptiles are animals than have been neglected in the research for all times. Some people have the opinion that these animals have fewer needs and demand less from their caretakers. The Aldabra Giant Tortoise lives on the Aldabra atoll outside the coast of Tanzania. The Aldabra tortoise population has varied throughout the years, but today the population is around 100.000 animals. The purpose of this study was to analyze the enclosure utilization of two Aldabra tortoises, a male and a female, at Parken Zoo in Eskilstuna, Sweden.

The purpose of this study is to examine some after-school teachers? perceptions about the outdoor stay at the after-school care centre in the schoolyard and in the leisure- environment.Five semi-structured interviews were conducted with the after-school teachers at five after-school care centres in the Stockholm area.In the theoretical part presents the leisure- governance and ongoing research on outdoor learning, research on the school playground and kindergarten local environment affects children in their development and learning, and after-school teachers? professional identity.The theoretical foundation is based on the phenomenographic approach.The questions are:? What is outdoor education according to the after-school teachers?? According to after-school teachers, what educational opportunities are provided by the schoolyard and the local environment?? How do the after-school teachers use the schoolyard and local environment?The result shows that outdoor education can be a knowledge invigorating complement to the indoor teaching and a way for the after-school centre to supplement the compulsory schoolday. The play outdoors can help to increase children's social development, creativity and imagination. The after-school teachers used the schoolyard and local environment for various purposes which may be due to different circumstances, knowledge and experience to carry out educational activities outdoors. But it may also depend on whether the after-school teacher focuses on the regular school day or in the afternoon at the after-school care centre..

The purpose of this thesis is to investigate how teachers perceive that they work with science in preschool through aesthetic learning processes as tools both in the indoor and outdoor environment and make visible what the educators' underlying beliefs are that affect how they perceive aesthetic learning processes as tools used to deepen children's understanding of different scientific phenomena.This is an interview study using the phenomenographic approach as a means and method to make visible and report on teachers' views on how aesthetic learning processes can be used to extend preschool children's learning about science. The results are analyzed and discussed based on John Dewey's theoretical ideas about children's learning, aesthetics and science.The study clearly shows that teachers' views on aesthetic learning processes and how they can be used in the work whit science is very divided and in some cases unreflective. The most striking results are that teachers often are unaware that they make use of aesthetic learning processes because they have a more limited view of what it is than we have in the paper. All informants have science as a core subject. Their focus of the activity is located at the showing and visualizeing of scientific phenomena and some of them express that they submit the aesthetic learning processes to their colleagues or that they collaborate with someone who has training in some art form.

 Valet av denna studie gjordes utifrån vårt intresse för och nyfikenhet på förskolans inomhusmiljö och Reggio Emiliafilosofins sätt att se på barnet och människan. Syftet med studien var att beskriva och analysera fyra pedagogers utsagor och resonemang kring inomhusmiljöns utformning på en specifikt utvald Reggio Emilia - inspirerad förskola. Avsikten var att försöka fånga bakomliggande tankar av betydelse för utformningen av inomhusmiljön ur ett pedagogperspektiv. Undersökningen baseras på fyra kvalitativa intervjuer med stöd av observationer. I litteraturgenomgången beskrivs Reggio Emiliafilosofin och hur den ser på barnet och lärandet, miljön och organisationen av den, avdelningar indelade efter barnens ålder samt materialets roll.

Utveckling av teknik skapar ständigt nya möjligheter men innebär också stora förändringar för företag och organisationer. Mobiltelefoner, surfplattor, bärbara datorer, mobilkommunikation och molnteknik gör det möjligt idag att inte längre vara bunden av tid, plats eller en enhet för att kunna arbeta. Förändringen innebär att en ny typ av flexibla och yteffektiva kontor med inga fasta arbetsplatser blir allt vanligare. Problemet med de så kallade flexkontoren är att veta var eller när en kollega befinner sig på kontoret är inte lika självklart, framförallt om det är stort kontor med flera våningsplan.Målsättningen med detta arbete är att ta fram och implementera en inomhuspositioneringstjänst eller en så kallad Location-Based Service, till företaget Connecta AB. Tjänsten ska göra det möjligt för användare att med hjälp av sin mobiltelefon dela med sig av sin nuvarande arbetsplats i en kontorsmiljö.Resultatet av arbetet är en Location Based Service som gör det möjligt för en användare att med hjälp av en Androidtelefon med stöd för kortdistanskommunikationstekniken Near Field Communcication att dela med sig av sin nuvarande arbetsplats.

The level of neonate mortality in a free ranging fallow deer (Dama dama) population at the Koberg estate in south western Sweden was investigated using radio-tracking techniques. During this study a total of 36 fawns (17 ?, 19 ?) were captured and marked with vhf or gps radio collars; 12 fawns in 2008 and 24 fawns in 2009. The neonate mortality calculated by the Kaplan-Meier method was 23.6 % and the mortality caused by predation was low, since only 1 of 8 non-surviving fawns died from predation by red fox (Vulpes vulpes). The spatial behavior of the fallow deer neonates were examined at two different levels i.e.

The purpose of this master?s thesis was to find problems that occur in the production line at Atlas Copco Rocktec Division, in order to decrease the costs of defect in quality. When the problems were distinguished, the authors ought to choose the problem with the highest improvement potential. One request from the constituent at Atlas Copco Rocktec Division was to connect the improvement to the document The Way We Produce. The document provides information and values about Atlas Copco and consists of 10 principles to be able to reach their vision.

Norconsult AB has developed a solarhousing concept, a house designed for the warm climate in the Middle East andwith large quantities of solar panels installed. The cooling system for the house was designed in an earlier report, the purpose of this thesis is to investigate the possibility of short and long term storage of thermal energy via an underground energy storage volume.Two different designs of the storage and three different filling materials have been integrated into a model to simulate different cases. The first design consisted of pipes installed in the ground, without insulation. The second design consisted of an insulated concrete box installed to prevent thermal energy from the surrounding soil to flow towards the lower temperature regions within the storage. The three different filling materials were dry saudi sand, water saturated saudi sand and the filling material used by the client for energy storage in Sweden.The results from the simulations show that neither of the designs, regardless of the filling material, managed to extract enough thermal energy from the house to the ground to uphold the demands of indoor climate.

Dooria Sweden AB is one of the main door- and doorframe manufacturers inSweden. They deliver door frames for indoor use for project oriented buildingsites, for these types of building sites the doorpost comes pre-assembled. DooriaAB wants to minimize transport to reduce impact on environment and thetransportation costs of pre-assembled doorframes, this thru simplifying themethod of assembly.The main purpose of this thesis has been to develop a prototype solution thatbrings the three parts of the doorframe together with the same properties regardingstability and tightness of joints as the current method of assembly. A profile ofdemands and wishes were created in collaboration with Mårten Dragstedt, DeputyDirector of Dooria Sverige ABBy following the chosen method the authors have been able to produce a fullyfunctional prototype that meet the demands that were put on the product. Catia V5R20 has been used as an aid during prototype construction and virtual tests.

Syftet med vårt examensarbete har varit att undersöka hur några valda pedagoger förhåller sig till utomhuspedagogik som en pedagogisk undervisningsmetod och diskutera dessa olika perspektiv av vad pedagogerna säger utifrån frågeställningarna i vårt syfte.Med hjälp av intervjuer har vi ställt frågor till fyra utvalda pedagoger som besitter skilda kunskaper och erfarenheter av utomhuspedagogik.I litteraturstudien mötte vi begrepp som forskare och teoretiker förknippade med utomhuspedagogik. Begrepp som direktkontakterfarenhet, sinnlig erfarenhet, autentisk lärandemiljö.Resultatet åskådliggör att pedagogerna ser fler fördelar än nackdelar med utomhuspedagogik. Några fördelar gällande utomhuspedagogiken framkom som mer rörelse i lärandet, bättre hälsa och att lära om objekt i sin verkliga miljö m.fl. En nackdel som flera av pedagogerna var överens om var personalbrist, tidsbristen gällande planering och de praktiska förberedelserna.Pedagogerna visade olika intresse för utomhuspedagogik men alla var överens om att det var en bra undervisningsmetod och några av dem ville gärna använda sig mer av det i sin undervisning i framtiden..
