Begomovirus susceptibility in wild Nicaraguan tomato populations

Tomato production is a common and important agricultural activity in Nicaragua. During the last decades tomato producers have suffered great yield losses due to begomoviruses (family Geminiviridae). The genome of begomoviruses generally consists of two circular ssDNA components, DNA-A and DNA-B. Tomato yellow leaf curl virus (TYLCV) is an example of a begomovirus with only one component. An approach to manage the virus epidemics has been to breed a cultivar with begomovirus resistance genes, which have been transferred from wild tomato.

Elstart Motorsåg

As requested by the company Husqvarna AB, we have developed a prototype of an electrical start device to a chainsaw. This was done through the development of new details in Catia, which has been integrated with existing details. Electrical components have been purchased by HAB electronics. In parallel with the modeling calculations was done, which was the basis for determine dimensions and the choice of an electric motor and gears. Prototype 1 improved gradually and led to prototype number 2, which became the final result.

Evaluation of Xilinx System Generator

This Master?s Thesis is an evaluation of the software Xilinx System Generator (XSG) and blockset for Matlab. XSG is a module to simulink developed by Xilinx in order to generate VHDL code directly from functions implemented in Matlab. The evaluation was made at Saab Avionics AB in Järfälla, north of Stockholm. In order to investigate the performance of this new module XSG to simulink, a model of a frequency estimator often used in digital radar receivers were implemented in Matlab using XSG.

Kirunametoden-Jämförelse emot en konventionell injusteringsmetod

AbstractWith increasing population and increasing demands for comfort and thus an increase in energy demand, it is necessary to examine various energy-efficiency measures. This work deals with the ability to control the flow through the heating system to achieve the desired comfort with as little energy as possibleA heating system contains of different parts, roughly speaking, you can divide it to three main components: Heat source, Distribution and Heat emitters. All components are working together to bring heat to the building. What is examined in this report are different ways of adjusting the flow and supply temperature and how it affects comfort and energy use in a building.At today ?s date the conventional method is to use a high flow through the heating system, which affects pressure drop and cooling of the fluid.

??Finns det ett samband mellan graden av periodiseringar och inflationsjusterade skattade framtida rörelseresultat? : - Empirisk studie av den europeiska aktiemarknaden.

In line with Sloan (1996) but on European data (STOXX 600) we are investigating whether stock prices reflect information about future earnings contained in the accrual and cash flow components. The extent to which current earnings performance persists into the future earnings performance is shown to depend on the relative magnitudes of the cash and accrual components of current earnings. Moreover, we still find a significant positive excess return (Jensen?s alpha and size-adjusted return) by replicating Sloans (1996) hedge portfolio by taking a long position in the stock of firms reporting relatively low levels of accruals and a short position in the stock of firms reporting relatively high levels of accruals. However, we find no evidence of negative excess returns for companies with relatively high accruals, this somewhat lower the total excess returns for all the portfolios.

Konstruktion av testrigg för moderna ångexpandrar

This report summarize what have been done during the Master of Science Thesis that Klas Schjelderup has written for the company RANOTOR Utvecklings AB. The company is developing modern steam engines and this work should develop a machine to perform tests on a new type of piston seal that hopefully could be used in the future. The steam engines will be both volumetric and energy compact, around 1600hp/literof cylinder volume, and it will have a lot of practical applications.The new type of piston seal is hydrostatic lubricated which means that a fluid is separating two faces that normally is in contact. In this case pressurized water is used to separate the piston seal from the cylinder wall. RANOTOR have earlier formulated that at least the expander in the modern steam engine have to be oil-free, due to other components functionality in the closed water system.

Ett välvilligt initiativ mot missbruk : En retorisk studie av IQ-initiativets eftertankefilmer

This paper aims to investigate the embalming process and the Balanites aegyptiaca from two pottery originated in ancient Egypt. The two objects were from Medelhavsmuseet in Stockholm. Samples were collected and analyzed with Fourier transform infrared spectrometry (FTIR) and Gas chromatography/mass spectrometry to identify which components the samples contained. The results show complex mixtures mainly consisting of resin origin from Pinaceae and the vegetable oils from the Balanites aegyptiaca..

Biomekanisk analys av patientlyft i team

Background: The majority of the occupational accidents and work-related diseases at Swedish workplaces occur due to poor ergonomics during lifts and transportation of objects. The most common consequence of poor ergonomic conditions is low back pain (LBP) and the risk of developing LBP increases as the mechanical loading on the intervertebral disks grows. This study has investigated the biomechanical loading in the low back during two different types of patient lifts. The first lift (lift A) is developed by Modern Arbetsteknik (MA) and the second lift (lift B) is a common lifting technique among care workers. Objectives: The aim of the study was to identify any advantages or disadvantages with MA?s lift, regarding shear and compression forces in the L5/S1 disc.

Utveckling och konstruktion av växellåda för elektroniskt styrda ställdon

The task of constructing a transmission has been provided to us by Digital Engineering, which is a company located in Hovmantorp. After meeting with Digital Engineering we started immediately with the brainstorming to find different ideas with pen and paper. After having presented a number of concepts for the company, we had finally chosen a winner. For the gearbox to be able to work in a good way the tension must never exceed the strain limit of the material. A prototype of the gearbox was produced by TKB Modell.

"Det finns inga ointresserade barn-om det finns betyder det ointresserade vuxna." : Hur lärare och barnskötare på förskolan ser på och hantera bråkiga, utmanande och utagerande barn?

In this study, my intention has been to examine how the ambiguous concept of corruption is constructed by the press. Emphasizing the media?s representations of the socially constructed and context-specific concept, this work adopts a critical perspective on discourse, together with an approach of conceptual history. Finland has for many years been appointed as one of the least corrupt countries in the world, signing several international conventions against corruption since the 1990s, which in turn has led to an increase in discussion regarding the phenomenon. By conducting a multi-method study, my aim has been to analyse the possible changes in the definition of ?corruption? in the Finnish newspaper Hufvudstadsbladet during the period 2000-2013.
