Biblioteket i lärarutbildningen : intervjuer med 13 blivande samhällskunskapslärare

A qualitative study of high school student teachers' ideas about libraries and school libraries.Interviews have been conducted with future teachers about the library's role in their education,their views on library functions in high school and whether they as teachers will use theschool library. The results show that the students have had some instruction concerninghow to use the library as students, but very little as regards their future teaching. The professorsof teacher education focus on the fact that the library should be used in high schoolteaching, not how to use it. Despite this, the student teachers look very positively upon libraries.Libraries play an important part in their education and they are all sure that they asteachers will use the school library, which includes interacting with the librarian. To them, themost important school library function is to allow pupils to seek information..

Majsensilage i Sverige

Maize for silage has been used as fodder in different parts of the world for a long time and has recently become more common also in Sweden. Our cold climate has been a problem as maize is very sensitive to low temperatures and frost. With new varieties and better techniques for cultivation it is now possible to grow maize in the southern and middle parts of Sweden. As for the north of Sweden the length of the cultivation season is a limiting factor as there are too few days with temperatures of over +10 ºC. Maize is well suited for silage making but oxygen-free conditions are required.

Gravar i stenskepp : Osteologisk analys av brända och obrända ben från skeppssättningar på Gotland

In this study bone material from six stone ship settings and a total of seven deposits of bones from two sites on the island of Gotland have been analyzed. Four ship settings from the burial site at Gålrum in Alskog parish and two from Tängelgårda in Lärbro parish. The ships contained both cremated remains and inhumations.  Human remains were identified in five of the analyzed ship settings and a minimum of six individuals was identified in total.  Animals were found in three of the ship settings, where one of them contained only the burned remains of a dog. Two of the ships contained inhumations, one in Gålrum and one in Tängelgårda.

Ett extra år i grundskolan

The basic idea behind an extra year in school was to offer students who have not read nine years in Swedish primary school an opportunity to prepare themselves to pass a high school. This first group that went an extra year in school consisted of eleven students who completed their studies and went on to high school. During the time the group expanded, the school received students from various schools in the same municipality. During the follow-up of these groups could be noted that there were many students who registered, but only few students completed their studies and went on to high school. The purpose of this study was to explore why leadership in the classroom is important for students.

Digital divide eller digital opportunity i Anacostia High School, Washington D.C. : en studie baserad på sistaårselever i High School

 Purpose/Aim: The goal of this thesis is to examine access and knowledge computers and the Internet among the senior-year students of Anacostia High School. Do the students of this facility have the same opportunity as the residents from better socioeconomical backgrounds or are they being excluded from the technology? Material/Method: To approach the thesis goal I have used a quantitative method. More specifically, a questionnaire was handed out to the senior year students at Anacostia High School. Main results: The study has shown that most of the students of Anacostia had in some way access to computers and Internet.

Ultraljud som diagnostiskt hjälpmedel vid subklinisk mastit hos ko :

This study was performed to investigate the possibility to use ultrasonography as a diagnostic tool for sub-clinical mastitis in dairy cows. Five cows with high cell counts, and four cows with low cell counts were selected as cases and controls, respectively, and their udders examined with ultrasound during a 5 week period. The image of the udders of cows with high cell counts exhibited small, hyper-echoic, rounded foci, approximately 1 cm in diameter, near the milk cisterns and the base of the teats. These changes were not found consistently in all cows with high cell count, however. Ultrasonography may be a valuable complementary tool in the diagnosis of sub-clinical mastitis in dairy cow, but more cases need to be monitored before its full value can be ascertained..

BIM vid installationsprojektering

Planet rendering plays an important role in universe visualization and geographic visualization. The recent tools and methods allow better data acquisition, usually with very high resolution. However in computer graphics, there is always the limitation on the resolution of geometry and texture due to numerical imprecision. Not many applications can handle high resolution data effectively.This thesis introduces, Implicit Surface Scene, a level of detail scene management inspired by dynamic coordinate system and SCALEGRAPH? which change over time depending on the current camera position relative to the planet surface.

Modellbaserad temperaturregleringav partikelfiltrets regenereringsprocess

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

Tidsupplösning vid miljövärdering av fjärrvärme : Kontorsbyggnad med solvärmeproduktion - en fallstudie

The demand for environmental assessments on buildings and energy consumption is increasing as well as the energy performance requirements for buildings. At the same time it is increasingly common with self-producers of heat and electricity generation.The main purpose with this master thesis is to investigate how time resolution affects the environmental assessment of energy consumption in office buildings connected to district heating (DH). Environmental assessments were done with both attributional LCA and consequential LCA with system expansion.Fortum´s DH system in Stockholm was analyzed and district heating production was simulated in a Matlab-model. Greenhouse gas (GHG) emissions for the production were calculated. The heat demand of the office Gångaren 16 in Stockholm was simulated in IDA ICE.

Friluftsliv på gymnasiet : En jämförelse mellan friluftslivsinslag i tre svenska gymnasieskolor

AimThe purpose with our study has been to investigate if upper secondary high schools in the south of Sweden, Stockholm and north of Sweden follow the outdoor education regulations stated in the curriculum (Lpf-94). Moreover, we aim to study if the teachers? previous experiences as well as the students affect the outdoor education. Finally, the purpose is to find out how the outdoor-life-education can be improved. These are the research questions:o How do the chosen high schools follow the outdoor education regulations stated in Lpf-94?o What obstacles, advantages and differences exist between the outdoor-life-education in these high schools?o In what way do the teachers? outdoor life experiences influence their education at school?o How can the students influence the outdoor education in their High Schools?o How can outdoor education be improved?MethodThe study is based upon data collected from four interviews with PE ( physical education) teachers from four different high schools.

Solcellsdrivning av distribuerade inbyggda system

The high level of energy consumption that the industrialised countries have reached and thepollution that this brings has long been a cause for analysis and debate, development and usageof so called renewable energy sources is therefore more important than ever. The energy in theelectromagnetic radiation from the sun is an interesting alternative. One way of harvesting thisenergy is by using solar cells, devices that generate DC current when exposed to electromagneticradiation.The goal of this master?s thesis was to design a solar powered power supply to Syntronic AB?sMidrange platform. The envisioned application is a stand-alone distributed embedded system,for example a node-based temperature monitoring system.

Ungdomars läsvanor och hur vi skulle kunna inspirera ungdomar att läsa mer skönlitteratur

AbstractThe purpose of this work is to try to find out how young people's reading habits among students look at different types of secondary school, ie. both theoretical and practical, and what factors might encourage them to read more. My questions have been; do young people read today? Is there any difference between city, gender or program? What can a teacher do to inspire young people to read more? I have made a questionnaire survey among different students at two different high schools in Skaraborg. The first school is a high school located in a medium sized town, where I made inquiries to the scientific program, social program, Business and Administration Program and the Electricity Program.

Gymnasiebibliotekarien ? informationsspecialist och pedagog: om gymnasiebibliotekariens yrkesroll och dess angränsningar till lärarrollen

The purpose of this study has been to examine different aspects of the professional role of the high school librarian, especially the educational role, and its delimitations to the teacher's role. The methods that were used were studies of literature within the subject area and qualitative interviews with high school librarians and high school teachers of social studies. Andrew Abbot's theory on the system of professions was used in the analysis of the results of the study. The high school librarians who were interviewed enabled access to information, both intellectually and physically. They helped students develop information seeking skills and they functioned as educators and counselors.

Bättre åtkomst till avverkningstrakter med anpassat marktryck från avverkningsmaskinerna

The global climate-change means increasing mean-temperature and higher precipitation in Sweden, which leads to shorter periods of frozen ground in the forest. At the same time the harvesting machines are getting bigger and more powerful. The forest industry aim at an even wood flow, and the ground damage has to be as low as possible. The two biggest causes for ground-damage is the bearing capacity of the forest ground and the ground-pressure of the harvesting machines. The aim of this study was to find out some rules for the machine choice considering ground pressure, when harvesting on ground with low bearing capacity.A field study, using a Valmet 890.3 forwarder, was carried out where different ground pressures and their effect on the ground were tested on two different types of ground.Additionally, an inventory of damaged harvesting grounds was made.
