Beräkning av rotationscentrum för knä-och höftled. : En kinematisk modell för kroppens rörelse baserad på experimentell data.

This report is part of a Bachelor?s degree corresponding to 15 creditsat the Royal Institute of Technology, Stockholm. The work hasbeen carried out by Max Wikander, author of the report, supervisedby Lanie Gutierrez-Farewik and Erik Dijkstra.Gait analysis includes measurement, characterization and assessmentof human movement and is used to assess kinematic or otherabnormalities during gait. Center of rotation and the axis of rotationof a joint are fundamental parameters in motion analysis. However,the ability to create individualized analysis is limited by the lack ofaccuracy when these parameters are calculated.

Molecular analysis of insecticide resistance in pollen beetle (Meligethes aeneus)

The escalating usage of pyrethroids has resulted in an increased awareness about resistance towards pyrethroids in insects. Pyrethroids inhibit voltage-sensitive sodium channels (VSSC) in nerve cell membranes and are composed of synthetic molecules based on pyrethrins present in pyrethrum extracts from Chrysanthemum species. VSSC are transmembrane proteins that are important for electric signalling over the membrane in insects. Mutations in the gene encoding the sodium channel have proved to be a common reason for resistance against pyrethroids. Pyrethroid resistance among pollen beetles is spread all over Sweden and also abroad and is increasing.

Inspiration för naturvetenskap : - utgående från en glashytta!

Allt färre elever väljer att läsa naturvetenskapliga ämnen. Skolan är uppenbarligen dålig på att stimulera intresset för det naturvetenskapliga området. Min utgångspunkt är att elevers/människors nyfikenhet måste väckas innan teoretiska fakta presenteras.I den här studien har två gymnasieklasser först fått besöka en glashytta för att därefter få en anknytande teorilektion och en laboration. Kvalitativ intervju med åtta elever visade att samtliga var positiva till min "teaching sequence - tema glas". Framförallt uppskattades möjligheten att, i den autentiska miljön, få lyssna på en person som var hängiven sitt arbete och "som visste vad han pratade om".

CTF ur ett ekonomiskt perspektiv : en analys för storskaliga växtodlingsföretag

Denna uppsats är skriven inom ämnet Företagsekonomi och omfattar 15 högskolepoäng på C-nivå på Institutionen för ekonomi vid Sveriges lantbruksuniversitet. Tanken bakom vår uppsats är att ge en bild av vad controlled traffic farming (hädanefter förkortat CTF) är, samt om odlingstekniken kan ge bättre lönsamhet i svenskt lantbruk. Förhoppningen är därmed att uppsatsen skall ge en grundförståelse inom ämnet. CTF innebär att permanenta körspår anläggs och att all fälttrafik sker i dessa körspår. Följderna av detta blir således att åkermarken mellan körspåren övergår till att vara mer lucker, eftersom lantbruksmaskinernas markpackning koncentreras till körspåren. Markpackning är ett av de stora problemen i dagens jordbruk och målet med CTF är att öka lönsamheten genom högre fältavkastning till följd av bättre markförhållanden för grödan. Studien utgörs av en jämförelse mellan konventionell plöjningsfri växtodling och odling med systemet CTF.

Genetic diversity of Roseroot (Rhodiola rosea L.) from Sweden, Greenland and Faroe Islands

Roseroot (R. rosea L.) has gained more attention the last years, mainly because of its phy-topharmacologic properties. Even though many reports in roseroot have been published, only a few articles are dealt with the genetic diversity. The Nordic Genetic Resource Center has collected Roseroot material from Sweden, Greenland and Faroe Islands under different expeditions. The samples were analysed to study the genetic diversity study.

En undersökning har genomförts med hjälp av en kooperativ utvärdering av fyra e-handelsapplikationer vilka innehåller olika typer av multimediala inslag har.Resultatet av undersökningen visar att multimediala inslag inverkar positivt på förtroendet för e-handelsapplikationer. Däremot finns indikationer på att för hög grad av multimedialt inslag inverkar negativt på förtroendet för e-handelsapplikationer..

Programmerning av en industrikap med GRAPH 7

This essay is divided in several different parts, but all are tied up together by a fact that we want to increase productivity. We hope to do that by programming the PLC and to reach this with a better security for the person how are going to handle the cutting machine under it?s cutting process. We should as well look for some other ways to come up with better instructions and way to work and handle yourself during work. This programming is done in GRAPH7.

Kol-14 datering : En litteraturstudie över hur kol-14 isotopen används för datering, samt utveckling och tillämpning av djup-åldersmodeller inom naturgeografin.

This literature study concerned the use and function of the radioactive isotope carbon-14, as a dating method of organic material, within the scientific field of physical geography. In this report it is presented the need of atmospheric calibration curves and the development of these as a necessity to translate carbon-14 years to calibrated calendar years. A number of common age-depth models that is used to give an approximation of an accumulation sequence and its related dates over the actual time period in different natural archives is presented and discussed. Different problems that commonly occur when age-depth models are utilized as for instance reservoir effects, contaminations or other age deviations are addressed and analyzed. The software CLAM in presented and discussed and was also used to produce age-depth models.

?-galaktosidas assay för studie av promotorregion i kloritdismutas från Ideonella dechloratans

Oxochlorates are anions with a partially naturally occurrence in nature but are also spread by human activities, including the paper industry. These compounds are harmful to both nature and humans, which makes it necessary to find a good way for their degradation. There are two different kinds of bacteria that can use oxochlorates as electron acceptors in their metabolism, bacteria that break down perchlorate and bacteria that break down both perchlorate and chlorate. A bacterium that can break down chlorate under anaerobic conditions is Ideonella dechloratans which holds the genes for chlorite dismutase and chlorate reductase which are enzymes for the degradation of chlorate. Gene expression and enzyme activity of chlorite dismutase are induced under anaerobic conditions, which makes it interesting to find out how this regulation functions in order to better exploit these bacteria in biological wastewater treatment.

Metaheuristic Multiple Sequence Alignment Optimisation

The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

Den försvunna sången - En studie av en rekonstruktionsprocess

Title: The lost song. A study of a reconstruction process. I was asked by the daughter of the Swedish composer Svea Welander (1898 1985) for help to reconstruct a now lost song for voice and piano originally composed by her mother, where the melody of the song was used in the second movement of her first string quartett. The song was composed in 1955, words by Wilhelm Ekelund. My aim has been to describe the process of reconstructing the song.

Analys av energiförbrukning, Akzo Nobel Functional Chemicals AB

The main purpose of this project was to make a survey of the steam and electricity consumption at Akzo Nobel Functional Chemistry AB and give suggestions of how to minimize them. These three different areas were focused on. First to make a survey of all the most important consumers, second to find the electricity consumption of the air compressors and the amount of waste heat produced from them. The third area was to calculate a model of how much fresh water that is used during a cooling sequence in the water based heating/cooling system of the reactors and give a suggestion of a suitable reuse for this water.The main result is a total survey of the energy consumption in steam and electricity. The survey shows that the second largest group after drying is heating of ventilation which gives big potentials of reducing the total steam consumption if there is a way of being self supporting in ventilation heat.

Extraterrestrisk och terrestrisk kromrik spinell i fanerozoiska kondenserade sediment

This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigationare compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromitegrains ( >63 ?Êm ) per kilogram limestone were found. These values have been interpreted as evidence of a twoorders of magnitude increase in the flux of extraterrestrial matter to Earth during a part of middle Ordovician.From an early Paleocene marine sedimentary sequence with known sedimentation rate in Zumaia, northernSpain, 90,5 kilogram of condensed limestone, dated to about 63 Ma, was sampled. The limestone was dissolved inhydrochloric- and hydrofluoric acid and the residue was sieved and searched for opaque minerals under the binocularmicroscope.
