This thesis has been carried out in autumn 2009 at Uppsala University for Boliden Mineral AB. Physical modelling has been used to model a comminution circuit. The model has then been linked to a PLC.When a concentrator is about to become operational Boliden Mineral AB have been looking for a way to test the PLC. The purpose of this report has therefore been to develop models for the subprocess in a concentrator and link these models to the PLC. The subprocess was a comminution circuit in Aitik36.

The purpose of this study is to investigate whether intensive teaching of reading strategies at an individual level can affect reading comprehension for students in second grade. A quantitative method with quasi-experimental design is used. All students in the experimental class trained on reading comprehension strategies at their particular level five times each. Before and after training a reading comprehension test was made. The reference class did the same test.

SammanfattningSyfte och frågeställningar: Syfte var att a) undersöka interbedömarreliabiliteten av testerna Neer sign (NS), Hawkins-Kennedy test (HKT) och Jobe test (JT), samt b) undersöka sambandet mellan resultatet vid NS, HKT och JT med resultatet vid muskuloskeletal ultraljudsundersökning hos patienter med subacromial smärta. Frågeställningarna var följande: Hur är interbedömarreliabiliteten för NS, HKT och JT? Vilken sensitivitet och specificitet har NS, HKT och JT som enskilda test respektive tillsammans i ett testbatteri för att diagnosticera subacromial smärta med muskuloskeletalt ultraljud som referensmetod? Hur väl samvarierar ett positivt impingementtest med ett onormalt lågt avstånd mellan humerus och acromion? Finns det någon skillnad av det acromiohumerala utrymmet (AHD) mellan personer med eller utan impingement i skuldran? Metod: 18 forskningspersoner (fp) med skulderbesvär (medelålder 54 år, besvärsduration median 2,25 mån) rekryterades konsekutivt.  Under samma dag undersöktes fp av två sjukgymnaster med testerna NS, HKT och JT. Ultraljudsundersökning utfördes inom åtta dagar och användes som referensmetod vid uträkning av sensitivitet och specificitet för de kliniska testerna.

A substation must be properly protected against lightning and other external effects to the equipment in the station or staff, for that we use relay protection. They should also protect against internal errors which may occur as ground faults. There are different types of protection relays, but most common are overcurrent-, distance-, residual current- and differential protection.The purpose of this thesis was to deepen our knowledge of relay protection and to use the theoretical knowledge we got from the university studies in the work process. In the process we discovered which parameters were the most essential and calculated these for all relay protections on the substation. We also carry out a comparison between two brands of relay protection, ABB and Alstom.During our work we will test and simulate the over-current relays in a program called NEPLAN, the program will also calculate the fault currents.

Development and accuracy tests of advanced exchange trading systems require well adjusted tools for testing. Aptness of these tools are probable to have a major impact on identification of bugs and verification of new functionality. Identifying erroneous parts and bottlenecks of the trading system is of outmost importance for the exchange as a whole since stability and correctness are two of the determinant factors its viability is measured by. This paper covers how this test-tool was created and the motivation behind the design choices made. The tool was created with the goal to be broad enough to cover the majority of cases that could arise, fast enough to be able to test the trading systems speed limitations (i.e.

From an early age kids learn that their good performance and efforts will be rewarded. Unfortunately, not all leaders in the media industry are rewarded or given the same opportunities to exercise their communicative leadership, according to studies in media research. The aim of our study is to highlight female managers' experiences of their communicative leadership in the Swe-dish media industry. This study was based on qualitative interviews with four female respondents in management positions. The core of the study concerns female communicative leadership and interpersonal communication.

When developing software that is meant to be distributed over several different computers and several different networks while still working together against a common goal there is a challenge in testing how updates within a single component will affect the system as a whole. Even if the performance of that specific component increases that is no guarantee for the increased performance of the entire system. Traditional methods of testing software becomes both hard and tedious when several different machines has to be involved for a single test and all of those machines has to be synchronized as well.This thesis has resulted in an exemplary application suite for testing distributed software. The thesis describes the method used for implementation as well as a description of the actual application suite that was developed. During the development several important factors and improvements for such a system was identified, which are described at the end of the thesis even though some of them never made it into the actual implementation.

Den här studien undersöker hur val av examinationssituationer påverka elevernas prestation i matematik. Syftet är att undersöka hur elever presterar utifrån olika bedömningssituationer. Vi använde oss av en empirisk studie där 12 sextonåriga elever i årskurs 9 genomförde uppgifter i decimaltal från Nationella prov för årskurs 9, år 2009.  I studien använder vi oss av både kvalitativ och kvantitativ data. Data samlades in vid två tillfällen med hjälp av skriftligt test och med hjälp av deltagande observationer under ett muntligt test i par. Hermeneutiken ligger till grund för tolkning av den kvalitativa data.

The predominant forestry harvesting method is based on the harvester-forwarder method, theharvester folds, branches and cuts trees, and sorts the logs into piles, while a forwarder transportsthe logs to a landing area.This master thesis work is about realization of a dynamic forwarder simulation model, and itspurpose is to provide an integrated forwarder simulation model in MATLAB/SimMechanicswhere the forwarder is based on a concept using pendulum arms to connect wheels and chassis.Active suspension control is developed and implemented into the simulation model, and finallycompared in simulation with passive suspension.In a first step, an integrated forwarder simulation model is developed, containing a simplifiedforwarder model, a tire-to-ground interaction model and a test track model. The simplifiedforwarder model is based a rigid multi-body system with a spring-damper suspension of thependulum arms. The tire-to-ground interaction model calculates the reaction forces, friction fromthe ground and applies the propulsion force. The test track model is a simplified version of thereal test track in Skogforsk. The propulsion wheel torque control is used to regulate theforwarder speed.

The purpose of the study is to get a deeper understanding in how the teachers work withthe students during the pedagogic meal. This by observing teachers during the schoollunchand see which pedagogic activities takes place. The paper intends to investigatehow teachers relate to, and act according to the guidelines that are applicable to theeducational meal by both the Swedish government and the schools.The study was conducted with the help of observations studies in two elementaryschools. The two municipalities looks different on the pedagogic meal. At both schoolsthe survey was conducted in the school canteen.

Thymidine kinase 1 (TK1) is an intracellular enzyme involved in ?the salvage pathway? where the uncomplete parts of DNA are transformed into DNA precursors. The expression of TK1 is cell cykle specific, with the highest level during S-phase when DNA-synthesis is most active. One kind of TK1 is present in serum and an increase in TK1 activity in serum is due to either the level of DNA synthesis in the body or the number of cells dying in a state of replication. This can be used and is used as a marker for prognosis and evaluation of treatment in human patients with leukemia and lymphoma.

Studiens fokus är sovjetkommunismen och elevers kunskaper i detta ämnesområde i förhållande till styrdokumenten för gymnasiekursen historia A. I studien utreds genom granskning av relevanta styrdokument kunskapsområdets betydelse, samhällets krav, skolsystemets krav samt gymnasieelevers kunskapsläge. Detta kunskapsläge har testats genom ett diagnostiskt test på en gymnasieskola i Skåne under våren 2006, vilken valts ut som ett least likely case på grund av skolans i övrigt goda resultat. Resultaten av testet visade på en låg kunskapsnivå om sovjetkommunismen och delvis om 1900-talets historia i allmänhet hos eleverna, i förhållande till kursmålen och betygskriteriet för betyget Godkänd i historia A. Vidare diskuteras eventuella implikationer av detta resultat och förslag ges till vidare studier..
