The research in this thesis attempts to understand what happens when children (3-6 years of age) interact with each other in the context of free play in two pre-school settings when adults are not involved. The aim of the study was to get a closer look at how children create relationships and how they protect and defend their interactional spaces. Data was gathered through ethnographically inspired methodology, using video observation to capture the everyday interactions of the children. Results were analyzed using a phenomenological approach to peer cultures. Previous research suggests that it is very important for children to maintain their interactions with peers and gaining access to play.

An automatic control system for calibration of pressure indicators has been constructed. This control system can be used as a complement to the calibration system located at AerotechTelub, division MainPartner, in Linköping. The calibration system used today contains some not wanted pressure changes, which is compensated by hand today. The new system presented in this report automates the calibrating process and simplifies the calibration. Suitable hardware as motor, controls card and so on have been found and software in the form of Visual Basic program has been developed.

The objectives of this research were to determine whether the natural rattan resources in Sulawesi, Indonesia can cope with the strongly increased harvesting pressure that has occurred over the last centuries. I was furthermore looking for patterns in the rattan population dynamics that might give a hint on how the harvesting system could be improved to ensure a maximum sustainable yield. To answer these questions, I developed an individual-based model to analyse the dynamics of rattan growth in connection with rattan harvests by locals to identify sustainable levels of rattan harvests around villages in Sulawesi, Indonesia. Scenarios with different harvesting intensities were run to compare the change in harvest amount. For a given harvesting pressure, scenarios with a high number of harvesters and a low harvesting frequency had the same effect as scenarios with high harvesting frequencies and a low number of harvesters.

In Uppsala CHP Plant, there are six pressure reducing valves to reduce the pressure from 15 to 3 bars, before six absorption heat pumps. During the process the energy is conserved but losses occur in form of exergy. The aim of this thesis is to reduce the losses of exergy. This can be done by letting turbines replace the pressure reducing valves.In this thesis an investigation has been done of the conditions today, the conditions after the change from pressure reducing valves to turbines and a comparison of three different types of turbine solutions. The three examined solutions are one turbine, several helical screw expanders and several small turbines in parallel with asynchronous generators.The six absorption heat pumps have been divided into two groups; one group of four and one group of two absorption heat pumps.

The aim with this study is to explore if and how linguistic learning takes places when four pairs ofstudents in grade one writes on the computer. Observations of eight students took place duringtwelve lessons to investigate what happened during their writing processes. This study isimportant because students? computer writing is a relatively new phenomenon in the Swedishprimary school.It is clear that the peer collaboration creates a complex interaction that becomes the platform, andalso the prerequisite, for successful language training. The method can clearly give students profitsin their linguistic development.

Equine metabolic syndrome (EMS) it?s a clinical condition that includes obesity, regional adiposity, insulin resistance (IR) and laminitis. A similar syndrome exists in human medi-cine, the metabolic syndrome (MS), were systemic hypertension also is a prominent fea-ture. The systemic hypertension seen in humans with MS is partly due to a vascular endo-thelial dysfunction with an enhanced endothelin-1 (ET-1) mediated vasoconstriction. There are indications that systemic hypertension might be a feature in EMS as well but if ET-1 is involved in the development of the systemic hypertension in horses is not known.

Stump treatment today requires large quantities of clean water mixed with the protective product Rotstop, to fully cover the stump surface. In order to reduce the water consumption without reducing the coverage of the stump surface, the pressure in the stump treatment device can be increased. Therefore, the Phlebiopsis gigantea (Fr.) Jül. suspension used as a biological control agent to prevent Heterobasidion annosum (Fr.) Bref. infection was pressure-tested.

AbstractThe purpose of this study has been to find out what attitude fifth graders have towards mathematics. This is done to get a better understanding of student?s feelings regarding about mathematics and what it is that makes mathematics fun or boring. My questions have been: What do the students think is fun, boring and difficult about mathematics? How do students think that a good mathematics teacher should be? Do the students see a difference in the mathematics teaching in easy compulsory school years?To find answers to my questions I have looked into prior research on students attitudes towards mathematics.

Background: Research on presenteeism has been performed mainly during the last 15 years, where several consequences on health such as cardiovascular disease and mortality have been identified. Studies have shown a relation between sickness absenteeism and presenteeism, where presenteeism could lead to long-term sickness absence. Aim: The aim of the present study was to investigate work-related and personal causes of sickness presenteeism. The study also aimed to identify the overall prevalence of sickness presence in Scandinavia, including potential occupational sectors with higher prevalence. Method: The study was literature based and consisted of 15 peer-reviewed scientific articles that were found by a systematic search in PubMed and Scopus.

Tillgängliggörande av upphovsrättsligt skyddat material på Internet som sker utan samtycke från upphovsrättsinnehavaren utgör i dagsläget en relativt stor och utbredd problematik, främst genom att Internet och teknikerna vilka tillämpas vid fildelning på senaste tiden har utvecklats och därmed resulterat i att fler och fler individer fildelar illegalt. Denna uppsats behandlar de olika teknikerna som används vid fildelning, juridiska tillämpningsområden, bevisbörda och identifiering av ansvarssubjekt samt rättsliga sanktioner. Syftet har vidare varit att utreda implementeringen av IPRED direktivet i den svenska rätten samt utreda huruvida denna reglering främst har haft en reparativ eller preventiv verkan på den illegala fildelningen. Uppsatsens slutliga resultat bygger främst på studier av den juridiska problematiken gällande identifiering av ansvarssubjekt samt bevisning och sanktioner, vilket i slutändan påvisade att implementeringen av IPRED direktivet i den svenska upphovsrätten hittills främst har lett till ett preventivt resultat snarare än ett reparativt..

Background: For the knowledge company the employees? competencies and knowledge are important assets. According to this, there has been a lot discussion about how to best take advantage of the employees? knowledge and create organizational learning. This organizational learning can be difficult to create due to the individuals? own goals and the fast changes in today?s society.

The aim of this study was to determine which type of fluid to use in trauma care to improve patient survival. The method used was a systematic review, where a total of 18 studies were reviewed and 13 included in the results. The inclusion criteria used in this study were Randomized controlled trial, or studies relevant for the purpose, written in English and published during the last ten years. The studies were identified in the PubMed data base. The results showed that in trauma with hypovolaemia, colloid infusion has a better effect than infusion of crystalloid fluid on blood pressure and colloid infusion reduced the body's cascade systems in a beneficial way. Colloid infusion administered to head injury patients lowered their intracranial pressure more than crystalloid infusion.

Att drabbas av KOL är något som påverkar vardagen på många sätt. Sjukdomen har ökat i omfattning och visar inga tecken på att minska. Det innebär att vårdpersonal alltmer kommer att möta dessa personer. Behandlingen är oftast inriktad mot de fysiska behoven utan att ta hänsyn till helheten. Syftet var att belysa dessa personers upplevelser av att leva med KOL för att kunna möta deras behov och ge det stöd de själva vill ha. Litteraturstudie valdes som metod och systematiska sökningar gjordes i databaserna Cinahl, Pubmed och PsycINFO.

The following thesis is examining compliance with EU-law from a member state perspective. The variation in the compliance level between the member states from 1995 to 2005 is analyzed to prove the fact that the Nordic member countries during the measured time period experienced a low number of infringements. The infringements that did occur were resolved faster and more efficient in the Nordic countries then in the other member states. The theory used to explain the Nordic compliance rate is divided between external and internal pressure in a pull and push model. The external pressure is illustrated with argumentative persuasion from the EU-commission to the individual member states; how the state responds to the persuasion in order to act compliant.

Post-anaesthetic myopathy (PAM) is a serious occasional complication of general anaesthesia in horses. It causes not only pain and suffering to the horse, but also suffering (trauma) to the owner with increased veterinary costs. In the worst case PAM can be fatal. The anaesthetic nurse must know which parameters have to be taken into consideration in the prevention of PAM, to be able to prevent it, and use that knowledge for the animals safety. The aim of this literature review was to investigate and make a presentation of the factors and measurements associated with PAM, with focus on how to monitor these measurements to prevent it from happening, and the advice a Veterinary nurse can give to the horse owner regarding this condition. According to literature there a few factors that greatly increase the risk of PAM, these include- hypotension, periods less than 60 mmHg significantly increases the risk.
