Produktivitetseffekter av flerträdshantering

The main purpose of this study is to investigate the productivity effects of multiple tree handling in thinnings. Other important elements have been to investigate in which extent multi-tree handling is used in stands with different stem volumes and the impact of collecting partially delimbed fuelwood assortments has on harvesting performance. The study is based on data from thinnings in Sydved and contractors' operating activities. Collection and compilation of operating schedules, number of stems and surveyed volumes from several contractors and a large number of executed orders underlying the results. Multiple tree handling is used to a much greater extent at lower average stem volumes. Prediction models for productivity of the multiple-tree handling harvesters in the study differ from the productivity models for single-tree handling. In the model developed in this study productivity is not as dependent of stem volume as reference models.

Frigörelse av fosfor från färskt, fryst och torkat växtmaterial : ett laboratorieförsök för att öka förståelsen för fosfordynamiken inom växtodlingen

Phosphorus is the single most potent contributor to eutrophication of freshwater and has also been shown to contribute to the toxic algae blooms in the Baltic sea. The dynamics and paths of losses of phosphorus from arable lands are not fully understood. It is known that phosphorus can be lost directly from plant material to water. In studies where plant material has been subjected to several freeze-thaw cycles, large amounts of phosphorus have been lost. Most studies have been conducted under field conditions, with many factors effecting the measured losses of phosphorus, such as weather and type of soil. This study was performed in a controlled environment without the presence of soil. Instead of soil, small glass beads were mixed with the plant materials in vessels, to make possible homogeneous leaching with water through the mixture of glass beads and plant materials. In this study, clover, ryegrass and dry straw were cut to pieces, approximately 2 cm long.

Lägesrapport

Arbetet är inte en ensaksfråga eller en djupanalys. Det rör vid raserande och dekonstruerande. Det handlar om att föreställningar byggs upp och kan brytas ner. Det handlar om hus, ytor, skikt och strukturer. Om samhället.

Matematiska arbetsmetoder : En kvalitativ undersökning om undervisningsmetoder i förhållande till nationella matematikprov

The purpose of this study is to provide a description of how mathematics teachers in grades 3 choose to work with mathematics and how it affects of student performance in national tests. The categories I will use are outdoor education, textbooks, learning materials and problem solving. Laboratory materials can be everyday materials and educational materials in which pupils have an abstract understanding of the subject. This survey was conducted through interviews and observations. The survey was also conducted in relation to student performance in national math tests.

Paradoxer i feminismens namn - En studie av genus och kultur ur ett poststrukturalistiskt feministiskt perspektiv

This thesis explores the validity of feminist poststructuralist theory in relation to gender and culture. Within the theoretical frame¬work of Judith Butler, combined with insights from the field of post-colonial theory, different perspectives of the dilemma of universalism are discussed. Primary sources for the study are policy documents from the Swedish government, literary texts and newspaper articles. The results show a number of paradoxes which need to be continually and critically kept unsolved. This does not mean an end to feminist engagement in other contexts than one's own but rather the need for theoretical awareness and self reflection.

Kvinnligt eller manligt - En studie av könsbedömningsmetodernas utveckling för humant material

This study focuses on the development of methods for sexual determination of human skeletal remains, mainly between the years 1981 to 2007. By comparing an older analysis from 1983 (Persson and Persson) with my own on the same material, a difference of 40% was shown, which indicates that the methods has changed through time, and that these should not be used for newer conclusions about a population if the method is not throughoutly described.The main cause of the difference was identified as a change in the reliability of the sexual indicators, rather than a total change of method. Any general tendencies did not show, it is however considered that the pelvic bones are able to make a better conformity between the analyses as opposed to using the cranium..

Vem skapar nyheterna? : En kvantitativ studie av nyheters ursprung och prioritering i svenska riksmedier

Syftet med undersökningen är att analysera varifrån nyheterna har sitt ursprung och hur återanvändandet av nyheter ser ut i fyra av de största riksmedierna under en arbetsvecka.De fyra medier som ingår i undersökningen är Svenska Dagbladet, Dagens Nyheter, Sveriges Televisions Rapport och Sveriges Radios Ekot. I undersökningen ingår 356 analysenheter och det är en kvantitativ undersökning. För att förstå och analysera resultatet har teorierna gatekeeping, mediernas kommersialisering och nyhetsvärdering använts.Undersökningens resultat visade bland annat att 27 procent av analysenheterna består av köpt eller kopierat material från nyhetsbyråer eller material som är omskrivet från andra medier. Undersökningen visar också att det är stora skillnader mellan olika medietyper. Den största andelen material från nyhetsbyråer kom från tidningarna Dagens Nyheter och Svenska Dagbladet (såväl procentuellt som i absoluta tal).

Jag läser och förstår det intressanta : Tillgänglig, förståelig och intressant information för personer med lindrig till måttlig utvecklingsstörning. Information på FUB:s webbplats, som skrift i samspråk med bild.

Most of the information online is difficult for people with cognitive disabilities to understand and assimilate. In this project I have had the expectation that this is possible to change. In cooperation with FUB, a Swedish organization working for people with cognitive disabilities, I have studied how to adapt content, pictures and writing to persons with the levels of mild to moderate cognitive disabilities. I have also taken the perspective ?design for all?, which means that you adapt a design for the weakest persons in the society to make it work for everyone.The purpose of my work is to study how to create a web text where content, writing and pictures are incorporated.To examine how to do this I have conducted qualitative interviews in which I have let the informants look at and read four different texts.

Laborativ matematikundervisning : Ett steg mot ett mer lustfyllt lärande

Syftet med detta examensarbete är att undersöka det laborativa arbetssättet i skolan utifrån ett lärarperspektiv. När och hur kan man använda laborativa material för att förbättra matematikundervisningen? Vi har försökt att besvara dessa frågor med hjälp av lärarintervjuer. Resultatet visar att lärarna i studien anser att fördelar med laborativ undervisning framförallt innebär att det blir konkret för eleverna och det öppnar möjligheter att koppla den abstrakta matematiken i läromedlet till elevernas förkunskaper i matematik. De menar vidare att laborationer är lustfyllt och att detta i sin tur kan leda till att eleverna blir mer motiverade till matematik.
