Från frö till planta : En studie om hur elever i årskurs ett och fyra tänker om fröet och dess utveckling till planta
Abstract The aim of this study was to explore and describe the pupils' thoughts on seed and its development into seedling. Twenty nine Swedish pupils at the age of 7 and 10 years old were interviewed about their knowledge of seeds.It turned out that pupils often have so-called everyday belief to describe the natural science phenomenon by connecting their explanations to phenomena in everyday life to which they are familiar. To describe the process of seed developing into seedling is something that most of the pupils believe to be difficult and this resulted mostly in the answer ?it is growing.? Children have some knowledge about what seeds need in order to germinate but they do not mention the importance of oxygen as a component of seed to be able to germinate and grow. They mean instead that it is sufficient with soil, water and sun.The older pupils, however, are more often than the younger pupils able to connect their reflections to a more scientifically correct description based on terms belonging to the phenomena, though these terms sometimes are wrongly used.
Illusionen om det svenska nationella fri- och rättighetsskyddet : och hur EU-domstolen kom att tillskansa sig kompetens på den direkta beskattningens område

På upptäcktsfärd i öppna förskolan : en institution som väcker frågor
Denna uppsats handlar om öppna förskolan, en verksamhet för barn och föräldrar som vissa kommuner väljer att tillhandahålla. Trots att verksamheten funnits drygt 30 år, är den sparsamt utforskad. Uppsatsarbetet har därför inriktats mot ett explorativt sökande efter olika föreställningar om öppna förskolan. Föreställningarna har på formuleringsarenan eftersökts i tryckta källor, och på realiseringsarenan genom en etnografiskt inspirerad fältstudie i två öppna förskolor. Syftet har varit att uppnå förståelse för arenornas föreställningar om öppna förskolan och hur dessa föreställningar förhåller sig till varandra.
BLÖDNING EFTER TONSILLEKTOMI VID OLIKA DISSEKTIONSTEKNIKER
ECG-Screening for young elite athletesAbstractBackgroundSudden cardiac death (SCD) during physical activity is a frightening and emotional tragedy that draws huge media attentions when it occurs. Fortunately it is a relatively uncommon occurrence but happens nonetheless to young athletes who often seems to be in perfect health. SCD is used as a term for sudden unexpected complications on the cardiovascular system that leads to a deadly outcome normally within the first hour of onset of symptoms and the cause is some sort of underlying cardiovascular disease that gets triggered by physical activity.Normally athletes gets divided into two groups dependent on age, over and under 35 years, and this studies focus is on the younger group since it is often during this period athletes are at the elite level. It is also in this category the most unexpected sudden deaths occur that is not due to coronary atherosclerosis, which is the dominant cause of death, and drastically increases, for people over 35 years old.AimThe aim of this study was to scientific and unbiased analyze peer-reviewed clinical articles todescribe the pros, cons and cost to implement an ECG-screening as a standard before physicalactivities for specifically defined elite athletes.MethodA systematic review was performed and after all data collection 21 articles was chosen to beused as a base for both background and analyze. At the end 10 articles was fulfilling the criteria to be used at the analyze and later the results.ResultsThe implementation of ECG-screening has reduced SCD in Italy by 89 % between the years 1979-2004.

Faktoter som påverkar valet av fritidsaktiviteter efter stroke : En intervjustudie med sju personer som drabbats av stroke
Syftet med studien var att undersöka vad som påverkar valet av fritidsaktiviteter hos personer som haft stroke och på vilket sätt fritidsaktiviteterna har förändrats. För att uppnå syftet valdes kvalitativa intervjuer som metod. Intervjuerna var semistrukturerade och utgick från en egengjord intervjuguide. Resultatet visade att utmaningen, gemenskapen, fysisk träning, självständighet, balans i vardagen, livssynen och rehabiliteringsteamet var faktorer som påverkade deltagarnas utförande av fritidsaktiviteter. Att anpassa fritidsaktiviteten eller att få personligt stöd var vanligare än att anpassa den fysiska miljön..
Den svarta jordens mysterier : en jämförande studie av två aktivitetsytor på stenåldersboplatsen Ajvide
The Pitted ware dwelling site Ajvide on the west coast of Gotland in the Baltic Sea is, because of its long continuity from the late Mesolithic to the middle of the Scandinavian Bronze Age, an interesting research object concerning Stone Age in the Baltic area. In this essay, a comparison between two activity areas on Ajvide have been carried out in the purpose of finding out what these areas may have been used for during the middle Neolithic. It has been showed, through zooarchaeological analyses of animal bones, that the areas most likely are depositing sites for slaughters refuse and food debris. If it is a result of everyday or more ceremonial activities is left undetermined..
The effects of Gotland pony grazing on forest composition and structure in Lojsta hed, south eastern Sweden
Livestock animals affect their environment in a number of different ways, mostly through grazing and trampling. This study focused on the effects of Gotland pony grazing on forest structure and diversity, and the impact on ground cover. To compare the fenced and grazed area with a reference area outside the enclosure a number of transects were used. The study showed that there was no significant difference in height structure and diversity between the compared sites; however, there were a significantly higher proportion of damaged trees inside the enclosure. The ground cover variables showed a higher amount of bare soil, plant litter and wood-rush (Luzula sp.) inside the enclosure whilst grass was more frequent in the reference area.
Tiden, hälsan och familjen : En intervjustudie av tidsbrist och dess konsekvenser för hälsan
Aim and scientific issuesThe aim was to identify potential health risks, for full-time working parents with small children, caused by time shortage. The intention was to better understand and help this particularly time-pressured group in society to achieve a healthier lifestyle. The identification was built upon their own opinions about possible health risks and upon an interpretation of the health risks from a health promoter?s perspective.How do full-time working parents with young children handle time-shortage in a health perspective, specified in the categories: sleep, recovery, nutrition, physical activity, social health and mental health?What consequences for health does time?shortage have for full-time working parents with young children?What do parents with young children think could help them to obtain a better health in everyday life? MethodThe study was based on a literature overview and semi-structured interviews with 6 people who were strategically selected: the interview objects were all full-time working or studying, had one child under 7 and lived together with a partner. All interviews were recorded using two dictaphones and were implemented, transcribed and analyzed by both writers of this essay to increase the reliability of the results.ResultsTime shortage is shown to be handled especially through priorities in the respondent?s lives.
Kostnadsutvecklingen inom flottningen i Dalälven 1900-1970
The paper, with a brief summary of timber floating in Sweden and also of some previous re-search in this field, contains a study on costs for timber-floating in the river Dalälven located in central Sweden. The public used timber-floating system in Dalälven and the historical background about this activity is described. The study is focused on the total costs for timber-floating in the public open floating system in Dalälven from 1900 to 1970, the year before the timber-floating was definitively closed down. Also the costs for separating the logs of a specific owner when they reached the point where they could be separated from the timber of other owners are analyzed..
Förskolegård för ett Reggio Emilia inspirerat tankesätt :
The shape and arrangement of the outdoor environment at a preschool has a critical
impact on the possibilities to practice different pedagogic activities (Grahn et al.1997). At the preschool at Edwin Ahlqvists road, the employees are inspired by Reggio Emilia in their way of thinking, and they consider their outdoor environment is not suitable for the pedagogic activities they use. Reggio Emilia is a city in the north of Italy (Wallin 2001). The preschools there are famous for their pedagogy, their creativity and their democratic way of working (Dahlbech & Johansson 1986). The Reggio Emilia pedagogy is constantly renewed and developed, but with the children?s needs in focus and simultaneously with the quick changes of the modern society.
Självförvållad sinnesförvirring : Konsekvenser av att fingera tillräknelighet istället för uppsåt vid gärningar som begåtts under självförvållad sinnesförvirring
This thesis, in the field of healthcare logistics, has been carried out at Hjärt- och Medicincentrum (HMC) at the University Hospital in Linköping during the fall and spring of 2012/2013. The thesis is done by two students at Linköping University at master?s level within the framework of Industrial Engineering and Management.As Sweden's county councils should not make a profit or loss, it is important that the councils are aware of how much care processes cost. Kardiologiska kliniken at HMC in Östergötland?s county council is one of the clinics that are profitable.
Självgående renslastare till sockerbetor :
Our greatest interest within crop farming is to grow sugarbeets, that?s why we want to
write about something new in this sector. We heard that a new concept had come to
Sweden so we wanted to find out everything about this machine.
This new technique was a self-propelled cleaning loader for sugarbeets. This machine is
supposed to replace a loader and a cleaning machine when the sugarbeets is going to be
loaded, cleaned and delivered to the sugerbeet factory. The cleaning loader picks up the
sugarbeets with rollers from the pile, which is placed close to the road.
