Denna studie har haft som syfte att synliggöra i vilka situationer förskolepedagoger och barn på en förskolas småbarnsavdelning använder sig av surfplattor. Faktorer som undersökts har varit vilka kontexter som utgör dessa situationer, vilka beståndsdelar dessa kontexter består av samt vilka motiv och aktiviteter som ligger till grund för användning av surfplattor. Studien har varit av kvalitativ karaktär och har undersökt en småbarnsavdelning med barn upp till tre år på en förskola i Stockholm. För att åstadkomma detta har semi-deltagande observationer skett på förskolan under fyra dagar. Den insamlade datan har ställts mot och analyserats efter Nardi, Dourish och Benyons teorier om kontext samt Blomberg, Burrell & Guests teori om etnografi.

The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.

The dry out criterion (MCPR) has been calculated for the most limiting H2-events for Forsmarks unit 2 and 3, at operating points that are normally not analyzed before each cycle. The operating points that normally are regarded as the ones with the lowest margin to dry out are the ones where the thermal power is the highest at agiven recirculation flow. This report shows that this is not the case for Forsmark 3. MCPR-values at partial power operating points are higher for the limiting case inside rather than on the boundary of the region of operation. It is therefore recommended that the method for determining the dry out criterion for Forsmark 3 is revised to account for this effect.

The aim of this study was to examine how the new established phenomenon of ?Internet drugs? causes challenges to organizations, both individually and in relation to collaboration. The study is based on qualitative semi-structured interviews with representatives from three organizations - one youth police unit, one medical addiction centre and four units working within social services. The theoretical approach that was used is theory about human service organizations, theory about collaboration and new institutional organizational theory. A conclusion is that the current drug classification is problematic and mainly challenging for the organizations that focus on prevention work and early interventions.

The company is recommended to decide how the producthandling between operations should be performed as guidelines for the productionteam.

Bakgrund och problem: Människor i dagens samhälle blir mer och mer medvetna och bryr sig mer om vart ifrån de produkter och tjänster de använder kommer ifrån. Begreppet hållbarhetsredovisning har därför blivit allt viktigare för företagen. De statliga företagen måste följa GRIs riktlinjer från och med år 2008. Hållbarhetsredovisning är inte längre frivilligt för de statligt ägda företagen, utan de måste i årsredovisningarna utarbeta rapporter där informationen kring miljöaspekter, socialt ansvar samt medarbetare redovisas. Men är kravet nödvändig för att få företagen att redovisa dessa områden, eller finns det andra påtryckningar som avgör vad företagen inkluderar i sin redovisning? Vilka faktorer utöver riktlinjerna som infördes 2007 kan förklara vad förändringar i de statliga företagens hållbarhetsredovisning beror på?Syfte: Syftet är att kartlägga förändringar i två statliga företag samt två privatägda företag.

Uppsatsen innefattar en teoretisk del som tagit form genom tillgänglig litteratur på ämnet samt en metoddel. Undersökningen grundar sig i teorier gällande olika typer av och olika synsätt på konflikter samt hanteringen av dem.

The purpose of this study is to investigate how teachers work with Autism pupils in two different schoolforms: a traditional elementary school and a language school. The study was based on three questions: 1. How do teachers in elementary school prepare, plan and implement reading and writing instruction to Autism pupils? 2. How do teachers in the language unit prepare, plan and implement their reading and writing instruction to Autism pupils? 3.

Världen krymper i och med ökad globalisering, ska vi kunna leva tillsammans på ett hållbart sätt måste vi alla ta vårt ansvar, stora som små, företag som privatpersoner. Detta medför starka argument för att ta fram lättanvända metoder för hållbarhetsgranskning. Sustainable Sweden Southeast AB (SSSE) är ett nätverksföretag som samlar och marknadsför sina delägares miljöteknikkompetens under ett gemensamt varumärke. SSSE har ett hållbarhetsråd som hjälper till att granska nya potentiella delägare, dock saknas i dag en fungerande metod för detta. På uppdrag av SSSE:s VD har en ny metod för granskning arbetats fram, en checklista med hållbarhetskriterier, vilket också är detta examensarbetes syfte.

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

Eggradien (ER) på ett skär är en mikrogeometri som utförs för att stärka skäreggen. På så sätt kan skäret användas i operationer där stora laster uppstår utan att till exempel resultera i en alltför kort livslängd. Men denna geometri har inte analyserats i lika stor utsträckning som andra skärgeometrier. En ej besvarad fråga är om eggavrundningen skall vara lika stor längs med egglinjen? Syftet med examensarbetet är att få en ökad kunskap om eggradiens påverkan vid svarvning.

Diskussionen om revisorers oberoende är idag mycket aktuell. På grund av bland annat Enron ? skandalen har oberoendefrågorna aktualiserats ytterligare. Från och med 1 januari 2002 har en lagstiftad analysmodell införts som syftar till att revisorn inför varje uppdrag tvingas ta ställning till olika oberoendehot. Denna analysmodell lämnar dock i vissa fall utrymme för revisorns egna tolkningar och därmed kan den uppfattas olika mellan olika revisorer.

A stay in the neonatal intensive care unit of greater than 5 days is one of the identified risks ofa sensorineural hearing loss. Preterm infants usually have at least one risk factor for hearingimpairment. The period from 25 weeks' gestation to 5 to 6 months of age is most critical tothe development of the auditory system. We think it is important to investigate hearingimpariment among infants born preterm, degree and type of hearing loss, risk factorsassociated with hearing loss and how the auditory system may be affected by preterm birth.ObjectiveA critical review of the current literature including studies of preterm infants born betweengestonal age 25-37. Our aim is to identify the most common type and degree of hearing lossamong infants born preterm and if there is an association between hearing loss and pretermbirth.MethodA literature search of Scopus and Pubmed resulted in 16 articles from 2000-2015ResultsMost of the infants in this study had a severe to profound sensorineural hearing loss.

Lake Bornsjön is situated 30 km southwest of Stockholm in a rift valley lake and consist three basins outstretched in northwest-southeast direction. The surface area is 6,7 km2 with a maximum depth of 18,3 meters, a mean depth of 9,8 meters and a retention time of the water of 6,5 years. The drainage area is 42 km2 and consists mainly of arable land (ca 1000 ha) and productive forestry land (2500 ha), but in the drainage area there are also restored and fairly newly constructed wetlands.Today the Stockholm area receives its drinking water from Lake Mälaren, but if there would be any pollution of this source, Lake Bornsjön would act as the water source. The area surrounding the lake was bought already in 1899 by Stockholm Stad for protection of the lake and was taken over 1993 by Stockholm Vatten AB. It has been a water protection area from 1988 and it was also accepted as a nature reserve in 1995.
