Galoppträning och körning med två travare
The aim of this study was to evaluate whether gallop training, rather than regular drive training, is worthwhile for trotters race performance. Another aim of the study was to expand the author?s riding- and driving capacity, and get more practical experience on the impact of interval training on trotters. The sample population in the study was two trotters, one Standardbred, and one cold-blood. Given the small sample population, the results of the study is only indicative on the effects of gallop training on trotters, and not conclusive.
Interpersonell problematik och arbetsallians i psykoterapi : Klientens upplevelse och förändring av interpersonell problematik och dess relation till arbetsallians i psykoterapi
The purpose of this study was to examine interpersonal problems and its relationship to the working alliance in psychotherapy. To examine this, data was used from Umeå and Lund University psychology practice client database, which clients responded to by using the self-assessment scales Inventory of Interpersonal Problems Circumplex Scales and the Working Alliance Inventory. The sample consisted of 201 participants that answered the questionnaires both before and after psychotherapy. A second sample consisted of 93 clients who specifically sought help for interpersonal problems. Results showed that the level of interpersonal problems before and after psychotherapy changes.
Studie av nötnings- och friktionsegenskaper vid höga temperaturer i Kanthal APMT
During this master thesis, wear and friction properties for the high-temperature alloy Kanthal APMT were studied. The results were also compared to 253MA. The initial tests showed, among other things, that the surface fineness of the muffle tubes matters in real applications like conveyor belts. A 253MA-sample wear-tested against a 253MA-tube showed lowest wear at 900°C while a pre-oxidized APMT-sample wear-tested against a APMT-tube had the lowest mean value of the friction force at 1100°C, compared to all other tests..
Simulering av simulinkmodeller medExtended Kalman FilterTidsoptimering av integrering
Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.
Gröna generationsskiften : Särskilt om dolt samägande
Syftet med denna uppsats är att modellera och prognostisera Sveriges varuexport, varuimport och handelsnetto. Vi använder oss av data från januari 1975 till och med augusti 2010 för respektive serie. Dessa data testas och jämförs i olika ARIMA- och SARIMA-modeller samt skattas även medelst säsongsreningsprogrammet TRAMO/SEATS. För de modeller som bäst passar serierna genomförs därefter in sample- och out of sample-analyser med felmåtten RMSE och MAPE. Modellerna med bäst felmått och som därpå väljs ut för att göra prognoser för serierna till och med augusti 2012 är (3,1,0)x(0,1,1) för export, (2,1,1)x(0,1,1) för import samt (0,1,1)x(0,1,1) skattad i TRAMO/SEATS för handelsnetto..

Comparison of four transport systems for enetric pathogens
ABSTRACT: Commercial swab transport systems are used for collection and transporting of fecal and other microbiological samples. This system must maintain viability and contribute to survival of microorganisms during transport to the laboratory. Four swab transport systems have been compared, eSwab, ?- Transwab and fecalSwab, all three with flocked swabs, and Copan Venturi Transystem with rayon swabs. The study followed the recommendations from the Clinical Laboratory Standard Institute; document M40-A for recovery of Samonella, Shigella, Yersinia and Neisseria gonorrhoeae after storage for 0, 6, 24, 48 and 72 h at room- (22-25°C) and refrigerated (2-8ºC) temperature.
Kvinnliga arbetstagare i sjuk- och äldrevården - faktorer som kan påverka graden av upplevd stress utanför arbetstid
The aim of this study was to examine the relations between women?s perceived stress off the job (dependent variable), responsability for household chores, emotional support, number of children living at home, neuroticism and age (independent variables). Comparisons between the present sample and two independent samples from previous research were made with regard to perceived stress and neuroticism. The sample of this study consisted of 186 women working in the fields of health care and geriatric care. The results showed that perceived stress correlated positively with neuroticism and number of children and negatively with emotional support, though the effectsizes for number of children and emotional support were fairly small.
Vad motiverar till ideellt arbete i ungdomsorganisationer?
Early studies of what motivates volunteering often have had an older sample and youth organizations have not been studied. A survey was used to study motives for volunteering in Swedish youth organizations. The importance of age and years of volunteering was studied. In the analysis 102 persons in age between 17 and 59 years participated. The participants ranked the motives as followed: knowledge, development, values, social, career and protection.
Hur mycket naturbetesmarker har vi idag? : skattning av areal via nationella, stickprovsbaserade inventeringar samt jämförelse mot befintliga informationskällor
To reach objectives within EU?s Habitatdirective and the national environmental objectives, more information about semi-natural pastures is required. The expression semi-natural pasture is used for pastures that during the latest time are uncultivated and unfertilized. Semi-natural pastures are important in many respects for example to conserve the biodiversity and for our cultural history. The aim of my study was to compile and calculate the area of semi-natural pastures by use existing sources of information.
Driver valutakursen, energipriser och subventioner livsmedelspriserna?
Den här uppsatsen visar att valutakursen och sekundärt energipriser har en hög förmåga att prediktera framtida rörelser i livsmedelspriser, både ?inom sample? och ?utanför sample?. Uppsatsen använder VAR-modeller och hittar empiriska belägg för att energipriser påverkar valutakursen (EUR/USD), som även indirekt påverkar livsmedelspriser. Teoretiskt och empiriskt visas att export- och produktionssubventioner reducerar eller ökar de ursprungliga priseffekterna vid chocker i valutakursen, och introducering av dessa samband visades öka precisionen av prognoserna. Resultatet är intressant för policybeslut eftersom identifieringen av vad som driver livsmedelspriserna visar att chocker i valutakursen har en omfattande effekt på framtida livsmedelspriser. .
Förbättring av den svenska kiselalgsmetoden-hantering av sedimentering
Benthic diatoms are used in Sweden for monitoring water quality in run-ning water; the method is also frequently used in other countries in Europe. One of the problems of the diatom method is the need for sedimentation of the fresh sample, to be able to decant the over standing water and add alco-hol as a preservations solution. To my knowledge, no results have been published about how long the settling time must be to ensure that the ben-thic diatoms really have settled down to avoid a loss of the diatoms when decanting the over standing water.
The aim of my investigation was to improve the Swedish method where the benthic diatoms are used for water quality monitoring. I wanted to find out the appropriate time necessary to wait until all diatoms have settled down before decanting the over standing water.
First, fresh benthic diatom samples were taken in the river Fyrisån and the lake Mälaren on different days. After arriving in the laboratory, I waited three different times (30 min, 60 and 180 min) for the diatoms to settle.
Vävtapeter i ny dräkt
Pattern design is a territory which has been widely explored by many during a long period of time. With this project I hope to shine a new light on wallpaper design, the area on which I?ve applied my patterns to.The inspiration for this wallpaper collection originated in a past project in which I experimented with weaving strips of paper together in different ways. During this time I found myself curious to investigate how this kind of weaving could be applied to textiles, wallpapers, etc.My main focus in this project has been about creating interesting patterns in which unexpected motifs are woven together. I?ve also touched on the subject of creating a kind of conceptual wallpaper constructed by weaving strips of wallpaper together.I based my patterns on a series of drawings that I created during the course leading up to this project.
Evaluation of preanalytic methods in order to shorten the processing time before identification of fungal microorganisms by the MALDI-TOF MS
Identification of fungi is based on macroscopic observations of morphology and microscopic characteristics. These conventional methods are time-consuming and requires expert knowledge. For the past years Matrix-assisted laser desorption ionization-time of flight mass spectrometry has been used for routine bacterial identification in clinical laboratories but not yet in the same extension for fungi. In this study three preanalytic preparation methods for fungi were evaluated in order to shorten the processing time in routine laboratory performance.Clinically relevant strains (n=18) of molds and dermatophytes were cultivated on agar plates and prepared according to the different preparation methods for protein extraction. Each strain was analyzed in quadruplicate by the MALDI Biotyper and the database Filamentous Fungi Library 1.0.The results showed that the genus and species identification rates of the least time-consuming direct extraction method were 33% and 11% respectively.
