Obalans mellan rot och krona skapar omplanteringschock i Prunus avium :

In this investigation has an attempt to find out whether so called transplanting shock depends on the moving and transplanting of trees, to other conditions, or if it is due to the imbalance between the root to shoot ratio. Seventy trees of Prunus avium have been part of the investigation and these trees have been divided into four different groups depending on methods of production, untouched on the field, trees still on the field but with root pruning, trees moved and planted into Root-Control-Bag, trees moved and planted into Spring-rings. To be able to answer the question, measurements of the length of the terminal shoots and the lateral shoots and the dimension of the stem growth have been done and also has a visual judgment of the trees vitality been performed. The result shows that it is not only the move of the trees that gives them transplanting shock, but rather the loss of roots which gives an imbalance between the root and crown..

Nivågrupper i matematik? : Synpunkter från lärare som undervisar i årskurs 7-9

Arbetets syfte är att undersöka vilka synpunkter matematiklärare i årskurs 7-9 har på nivågrupper som undervisningsform. Detta för att försöka klargöra varför vissa skolor/lärare väljer att undervisa i nivågrupper och andra inte. Det finns både forskning som stödjer och som inte stödjer valet av nivågrupper. En av anledningarna till den oenighet som råder är att frågan om nivågruppering har både en pedagogisk och en ideologisk aspekt.Uppsatsen inleds med en bakgrund bestående av en kort historik, styrdokument och en sammanställning av forskning kring nivågrupper i matematik. Därefter presenteras en enkätundersökning som riktar sig till matematiklärare i årskurs 7-9.

Jämförelse mellan BKR/BSK och Eurokoders behandling av utmattning i traversbalkar med tillhörande svetsfogar

This report has been performed for WSP Construction Design located at Arenavägen 7 in Stockholm. WSP Construction Design is one of the leading departments in Sweden in construction solutions regarding everything from building construction to industrial building. Great competencies regarding steel, wood and concrete constructions are available within the department which is well sought.Crane girders used in the industry are exposed to large loads that vary over time that includes instantaneous lifts and the crane girders movement which lead to the phenomenon fatigue in the crane girder and its ingoing welds. A control of fatigue needs to be performed after a certain lifespan measured in time which in turn is converted to a number of loadcycles. When the number of loadcycles amounts to a greater number the input welds resistance will have been reduced and the rate of utilization thereby increased.

Långsiktigt spårväxelunderhåll - Förutsättningar och möjligheter

Due to their complexity and heavy wear from rail traffic, switches are a sensitive part of the railway infrastructure and moreover expensive to maintain. Furthermore, increasing railway traffic not only accelerates the wear rate but also obstructs the necessary maintenance measures. This paper examines the opportunities for a transition to a long-term maintenance strategy in the Swedish railway network. It contains a study of the maintenance strategy of Banverket, and also analyses statistics of errors in the railway infrastructure. The survey was completed utilising interviews with infrastructure managers, maintenance contractors, planners of railway operations and the Banverket material service department.

Skjuvhållfasthet och deformationsegenskaper för Uppsalalera med CRS och standardödometer

Shear Strength and Deformation Characteristics of Uppsala Clay with CRS and Standard OedometerTyra Morell Bonin & Magdalena MählerTo see how much a clay compact under different pressure one can use several different methods and in this project, two methods were used, the Standard Oedometer and a CRS apparatus. A Standard Oedometer is a full-time manual device and the CRS apparatus is a modern electric and automatic device. The aim of the project was to see similarities and differences between the two methods and examine which method that were most reliable. This has been done with repeated laboratory tests and afterward evaluations. With this information one can get a picture of how the clay will behave and how it will deform in nature.

Findus Sverige AB:s distribution av frysta ärtor via cross-docking : Kartläggning och utvärdering av säsong 2008

Findus Sverige AB, referred to asFindus from now on, harvests peas during a period ofaround 50 days during the summer. The harvest generates about 30 000 tonnes of peas which gives around 40 000 pallets to distribute to the warehouses which Findus uses for final storage. Three hours after the peas are picked in the fields, they have to be frozen to keep their good taste and quality. Because of this the pallets are marked with a preliminary label with quality classification of the content. The Findus quality department then has one day to determine the correct quality of each pallet.

Kapacitetsberäkningsmodell för materialhanteringsflödet på Ericsson i Kumla

Ericsson?s factory in Kumla, Modules Kumla, became a hub for radio modules and micro base stations, which enables mobile communication through radio base stations, in 2004. Because of this the factory focuses more on the logistics operations. This has led to a need to be able to plan the capacity for the materials handling system. This master thesis has therefore been performed at Modules Kumla to develop a capacity calculation model for the material handling flow during the autumn of 2005.The work has contained a mapping of the material handling flow regarding to which activities was performed and how much time they consumed.

Strategier vid generationsskifte : ekonomiska implikationer för olika intressenter

A large number of farms within the agricultural sector will shortly be facing a point of time where the farm will be transferred to the next generation.

Komplettering av befintlig bergvärmekälla med en ny effektiv värmepump och uteluftkonvektor

Projektet avser att undersöka vilka fördelar ett mindre familjehus kan dra av ett kombinationssystem med bergvärme och en uteluftkonvektor vid byte till en mer effektiv bergvärmepump. Uteluftkonvektorn är ett komplement till det befintliga borrhålet som är underdimensionerat mot den nya bergvärmepumpen. Under sommarhalvåret drivs utekonvektorn för återhämtning av hålet. Vid de varmaste dagarna på året återladdas även borrhålet av utekonvektorn.I detta arbete undersöks hur den årliga värmefaktorn och temperaturen i borrhålet påverkas av en kombinationslösning jämfört med att endast använda energibrunnen. En analys gjordes på hur husets effektbehov varierar under ett år med hänsyn till svensk byggnorm under 1980-talet, då huset byggdes. Från denna information kunde de olika driftfallen undersökas och fastställas.

Empiriska växelkursmodeller för den svenska kronan - Är det någon som fungerar?

The forecast ability of four well-known exchange rate models for theSwedish krona is tested in this thesis. The models that are tested arethe purchase power parity, the real interest differential model, thesticky-price model and a productivity model. In addition to thebenchmark, the random walk, they are also compared to each other.They are all tested on three different horizons one quarter, two quartersand four quarters. The mean squared forecast error criteria and thedirection of change criteria are used for evaluation of the forecastability. Only in a couple of cases are the forecast ability of thetheoretical based models significant better than the random walk..
