Structuring education so that students can discover connections between schoolwork and their everyday lives is a crucial task for a teacher. This is especially true in today?s school system that seeks to foster a spirit of lifelong learning, since educational motivation depends on being able to connect to the tasks at hand. In a system where these connections are not present, students will be motivated only by institutional mechanisms such as test results and grades. This leads to them using a number of techniques for ?optimizing the system? by getting maximal results for minimal effort. This essay looks at two pedagogical movements that aim to decrease the gap between schoolwork and students? reality.

Amyotrophic lateral sclerosis is one of the major neurodegenerative diseases, causing an ascending paralysis that usually kills the patient within a few years from disease onset. The motor neurons show aggregates of proteins which in approximately 20 % of cases of the familial form contain mutated SOD1 protein. Trehalose is a disaccharide which has been shown to reduce protein aggregation and increase viability in cell models and alleviate symptoms in animal models of several neurodegenerative diseases associated with protein aggregation. When given orally to the SOD1G93A mouse model of ALS, trehalose failed to slow down the disease progression, which has led to questions about the uptake and distribution of the molecule in this mouse strain. The aim of this study was to investigate whether significant levels of trehalose reach the central nervous system of the SOD1G93A mouse after oral administration. This was performed by a trehalose assay of the brain of trehalose treated animals. A glucose assay was optimised for use in small samples of brain lysate after the digestion of trehalose into glucose by trehalase, and the difference in glucose concentration before and after digestion represented the trehalose level.

Background: A common view about people with diagnosed psychosis is that they are socially withdrawn and that they neither cope nor want to engage in social relationships. Newly published specialist books on this subject also support this view.Aims: To unveil further dimensions of the phenomena by explorative analyzing consumers? own depictions about their ?social relationships".Method: The material is taken from a larger study that followed consumers regularly during a lapse of 3 years. Within this material 15 interviews from three respondents were chosen, a selection which gives maximal spreading concerning age, sex and background. The interviews where analyzed by methods based on Grounded Theory.Results: Three main dimensions were identified: supportive relationships, difficulties and social withdrawal.

Akut hamstringskada är en vanlig skada inom fotboll. Skadan utgör 12% av alla skador som uppkommer inom fotboll. Lag på elitnivå drabbas per år av i snitt 3,4 skador, med en rehabiliteringstid på i snitt 21,5 dagar. Syftet med studien var att undersöka om det fanns en obalans i styrka mellan hamstringmuskulatur och m. quadriceps i det skadade jämfört med det icke skadade benet.

This thesis discusses main problems associated with dictionary-based Cross-Language Information Retrieval as lexical and translational ambiguity of query terms, translation of compounds and phrases, dictionary limitation. The purpose of the study is to investigate how query structure influences the effectiveness of CLIR regarding performance of three query types: original query, unstructured query and structured query. Query structuring refers to the application of #syn-operator to group query terms. The study comprises an experiment that was performed in the InQuery IR system with TrecUta database that contains 550,000 news articles from different American newspapers. 24 topics were used for the experiment.

In order to reduce greenhouse gas emissions from human activities fossil fuels will have to be replaced with renewable energy alternatives, such as bioenergy. Sweden has a great potential to produce bioenergy derived from forest products and there is currently a great interest within Sweden in using stumps for bioenergy production. However, the environmental consequences of the method need to be investigated before stump removal can be performed on a large scale. Swedish forest soils contain large carbon pools and a different land use may change conditions so that soils that presently act as sinks of carbon could potentially turn into sources of carbon release instead. This study investigates the initial effects of stump harvesting on the emissions of three greenhouse gases, carbon dioxide, methane and nitrous oxide. The emissions were measured from the soil surface in a Norway spruce forest located in the southern part of Sweden.

Höft- och knäprotesoperationer är idag en vanlig operation vid artros i höft- och knäled. Trotsminutiösa infektionsförebyggande förberedelser inför operationen drabbas ändå en delpatienter av postoperativa infektioner. Vid ortopedisk proteskirurgi är postoperativainfektioner ett direkt hot mot den nya inopererade leden och kan leda till långabehandlingstider som påverkar patientens livskvalitet under lång tid.Syftet med studien var att utforska patienters möjlighet till delaktighet i tidig upptäckt avpostoperativ infektion utifrån given information vid operation för höft- eller knäprotes.Semi-strukturerade intervjuer genomfördes med tio patienter med diagnostiserad postoperativinfektion efter höft- eller knäprotesoperation. Transkriberade intervjuer analyserades medinnehållsanalys. Journaler granskades för att beskriva patientens tidigare sjukdomar.Resultatet visade att första tecknen på infektion kan beskrivas med temat: Vad är normalt ochvad är inte normalt.

Magnesium is an essential mineral that is important for several physiologic and biochemical processes in the body. Deficiency of magnesium is mainly associated with grass tetany, but can also appear in cows during the indoor period. Since long it is known that potassium has a negative effect on the absorption of magnesium. Due to the fact that potassium fertilisation leads to a higher potassium content in forage, it is of interest to study interactions of potassium on the magnesium balance in dairy cows. There are few studies about magnesium feeding to dairy cows in Sweden and the purpose of this study was to investigate how much magnesium and from which feed-sources dairy cows in Sweden get their magnesium. Data was collected from seven farms in the northern part of Uppland and from seven farms in Skaraborg in Sweden.

Kväve är ett element med både positiva och negativa effekter på ett kolståls egenskaper och det är därför av yttersta vikt att under tillverkningsprocessen kontrollera kvävehalten i stålet med hänsyn till kravet på slutproduktens egenskaper. Möjligheten att styra stålets slutliga kvävehalt påverkas i hög grad av förloppet i LD-processen, d.v.s. det processteg där högkolhaltigt råjärn konverteras till lågkolhaltigt råstål, i huvudsak genom tillförsel av ren syrgas. Både kol och syre har en stark inverkan på kvävets löslighet i flytande stål. Ett flertal planerade försök med provtagning under pågående LD-process och analys med LECO® har legat till grund för en kartläggning av kväveförloppet, särskilt med avseende på konvertering av stål som återanvänds i processen, s.k.

AimThe aim of this study was to evaluate the activity recorded with electromyography (EMG) fine-wire electrodes, in transversus abdominis (TrA) and rectus abdominis (RA) while performing various stabilization exercises, and to investigate how the level of activation was affected by specific instructionsMethodTen physically active women (27.1 ± 5.5year, 1.74 ± 0.05 m, 67.1 ± 8.6 kg) performed six different stabilization exercises (four lying supine with bent knees and hips and two in four point kneeling). They performed two sets of exercises, the first without and the second with specific instructions. The specific instruction was ?abdominal hollowing to activate? TrA. The fine-wire electrodes were inserted bilateral into TrA and RA with an injection needle with guidance from an ultrasound.

Every spring you can see newborn foals running on fields among the mare. But some unfortunate end up visiting the equine hospital requiring surgery. This is a challenge for the anesthetist because of the neonatal foal?s unique physiology. Therefore you need to take these differences under consideration when you anesthetize foals.

LKAB:s brytning av järnmalm långt ned i berget orsakar rörelser och sättningar i marken som till stor del påverkar bebyggelsen i Kiruna centralort. I och med detta har det bestämts att Kiruna stad under närmsta åren kommer att flyttas och byggas om. Kiruna kommun utlyste i samband med offentliggörandet av stadsflytten en arkitekttävling gällande byggnationen av deras nya stadshus. Tävlingen vanns av danska firman Henning Larsen Architects vilka valde att i samarbete med konstruktörerna på WSP:s kontor i Luleå projektera Kirunas nya stadshus.I detta examensarbete utförs en studie av stadshusets atrium där klimatet studeras genom CFD simuleringar (datorbaserade flödessimuleringar). I studien har klimatanalyserna begränsats till sex stycken extremfall där temperaturfördelning, tryckfördelning samt lufthastighet beskrivs.

Syftet med studien är att utforska och förtydliga vad likvärdighet idag uppfattas som hos skolans huvudmän, rektorer och lärare, samt hur likvärdighet eftersträvas inom grundskolan. Det finns en önskan om att uppmärksamma en problematik med strävan efter minskade resultatskillnader mellan elever som verkar motsäga likvärdighetsmålet att alla elever ska utvecklas så långt som möjligt.Studien har utförts i Linköpings kommun där huvudmän, rektorer och lärare inom grundskolans högstadie har intervjuats. Likvärdighet definieras av respondenterna som att ge alla elever samma möjlighet och samma chans. Detta genom en lyckad skolgång för att nå kunskapskraven samt möjlighet till maximal utveckling. Resultaten visar att små resultatskillnader mellan elever och mellan skolor inte eftersträvas, utan varje elevs maximala utveckling anses viktigare för likvärdigheten.

The aim with this thesis is to make a comparison between forcing tulips in a hydroponic system and the forcing off tulips that have been planted in soil. The results are mostly based on interviews with six Dutch and one Swedish tulip forcer and the managing director at the Horticultural Research Centre, Proeftuin Zwaagdijke, in the Netherlands. There are benefits and disadvantages with both methods. Tulip bulbs planted in soil seem to get a brighter colour after forcing, compared with those forced ?in water?.
