With a changing climate, we can expect higher temperatures and more precipitation in Sweden.As the temperature increases, new weed species are expected to migrate in from more southerlylatitudes, resulting in requests for new techniques for weed control. In addition, we might see agreater number of weed species and higher biomass production due to increased concentrationof CO2 in the atmosphere.Increased understanding of the biology of specific weed species will become more importantin future weed control. This will help to control the weeds more efficiently. Higher prices onpesticides and a public demand for reduced use of pesticides make growers more inclined to usemechanical weed control on a larger scale and to a greater extent prevent weed establishmentbefore sowing. A well-planned crop rotation is the most important preventive measure, whichmight also include delayed sowing, and dark harrowing and sowing.Research takes place on many levels within the weed area and several alternative methodsare being developed.

By the year of 2007, 97 % of all listed companies in Europe had a CSR strategy described on their website. As the concept of CSR during the last decades has increased rapidly in popularity, a need to understand how such a strategy can be implemented has followed. While working with CSR in an integrated manner shows similarities to other popular management ideas, such as Lean and TQM, companies applying to a CSR strategy has been shown to be under higher scrutiny from media and NGO:s. Through a case study this thesis examines how these special circumstances of a CSR strategy makes The Body Shop use organizational control to avoid being subject to scandals due to not fulfilling the promises made to its customers. The results show that The Body Shop's commitment to CSR creates a need for a stringent bureaucratic control system that highly restricts the freedom of action for its employees.

Lek kan ses som ett flerdimensionellt och komplext fenomen. F?rskolans l?roplan framh?ller att lek och l?rande ska bilda en helhet samt att lek ?r en f?ruts?ttning f?r barns utveckling. Fri lek ?r ett begrepp som ofta anv?nds i praktiken men som ocks? kan uppfattas som sv?r att arbeta med d? gr?nsen f?r vad som ?r fritt ?r diffust och vad frihet egentligen inneb?r i f?rskolans vardag.

Syftet med studien var att ta reda pa? hur man kan fra?mja lek fo?r barn med autistiska symptom som bor pa? korttidsboenden. En kvalitativ intervjuunderso?kning gjordes med sex deltagare och analyserades sedan genom en tolkande fenomenologisk analys (IPA). Fyra huvudteman med tillho?rande tva? underteman var valdes ut.

The function of budgetary controls is to control the resource allocation within companies. It can also be an instrument for measure and control subordinates and/or business units? performance (Van der Stede 2001). This paper concerns the latter; when the budgetary control function is used to measure and control subordinates performance based on budget. Previous research in this area has not yet accomplished to explain the effects of tight budgetary control which Hartman (2000) considers as the main issue to be concerned about in management accounting research.Previous research has presented contradictory findings regarding tight budgetary control explained by positive effects as well as negative effects during the last decades.

A cars powertrain consists of everything that is needed for its propulsion. The components in the driveline that transfer the power from the engine to the driven wheels are not absolutely stiff, hence they will wind up due to the torque and act as torsion springs. If you suddenly demand a bigger torque by stepping on the accelerator pedal, a so called tip in manoeuvre, and that torque is acquired from the engine as quickly as possible, the driveline will not be able to transfer that fast torque change due to its weakness and as a result it will start to oscillate. These oscillations will be transferred to the driven wheels and make the car to accelerate jerkily which will be experienced as uncomfortable by the passengers. Furthermore, there is a backlash in the driveline that will make the weakness in the driveline even more excited than it should have been if the backlash did not existed.To avoid too big problems with these oscillations there is a control system that controls the demanded torque.

Game balance can be considerd complex - there are many factors that play a role in the perception of balance. This thesis examines complexity, game theory and intution in an effort to disconver more about the perception of balance. The findings are that tactical and strategical choices that are presented for a player need to be interesting, not to complex and not to obvious. The importance lies in the estimation of the result that the player does when making a choice..

This report treats two assignments that concerns the biofuel furnace at Billerud SkÀrblacka AB and how these assignments were solved. The assignments were: reducing the number of CO-spikes and tuning the overfire air control loop. To reduce the number of CO-spikes the possibility that skewness in mass distribution affects the number of CO-spikes were study. The skewnwss of mass distribution was controled and adjusted with two experiments. The conclusion that was made is that the skewness of mass distribution were not sufficient enough to affect the number of CO-spikes.

Digital teknologi ?r ett omtalat ?mne i f?rskolan och 2024 f?rv?ntas en reviderad l?roplan f?r f?rskolan publiceras med syfte att g?ra f?rskolan sk?rmfri. Detta kan skapa funderingar eftersom det var vid den tidigare revideringen f?r knappt sex ?r sedan som digitalisering i f?rskolan implementerades. Den nya revideringen ?r baserad p? forskningsresultat fr?n det neurovetenskapliga f?ltet som visar negativa effekter p? barns utveckling kopplat till sk?rmanv?ndning.

I orkestermiljo?n blir det livsla?nga la?randet konkretiserat da? varje arbetsvecka inneba?r instudering av ett nytt konsertprogram med da?rpa? fo?ljande konsert. Syftet med denna studie var att beskriva individuella instuderingsstrategier liksom det kollektiva, samtidiga, musikaliska la?randet hos erfarna orkestermusiker i ?den tredje a?ldern?; mellan 50 och 65 a?r. Sju orkestermusiker intervjuades.

A growing problem in Swedish herbicide free agriculture, the Canadian thistle has been the object of several new trials, seeking methods for non-chemical weed control. The new trials have mainly confirmed earlier experiences; that the most successful methods of control are springtime ploughing, repeated cutting and competition from a stout crop. Row hoeing has also been proven effective. As opposed to earlier recommendations, half season fallow has shown to be a risky and often ineffective method of control. Trials regarding biological methods have shown that above others thistle rust (Puccinia punctiformis) may have the potential of controlling Canadian thistle the future. .

The aim of this study is to analyze how problems are represented within SOU 2008:27. Further more, the aim is to analyze how the new subject plan for history can bee seen as a product of this document. The method used, and the theoretical frame of the study, is based on Carol Lee Bacchi?s ?whatŽs the problem represented to be?? approach, which basic principle is that policies are filled with representations of problems and that these representations need to be examined. These problem representations are then themselves subject for scrutiny, the second step being an analysis of the texts presumptions and assumptions concerning view of man and perception of knowledge. The results show, among other things, that a problem representations can be found in the SOU; the school system is too vague and unclear.

This thesis is a feasibility study for a future product development project. The purpose ofthis project is to evaluate the possibilities and difficulties associated with the design of anelectric power assist servo for all terrain vehicles (ATVs). The project has been carriedout in collaboration with Nira Control AB. Nira designs and manufactures electric andelectro mechanic products mainly for the motor sport market segment.Nira Control AB is developing a fuel injection system for a new line of large ATVs oncommission. To be able to compete with manufacturers like Yamaha and Honda thecommissioner should be able to offer optional power assist steering.
