Assessment and Reaction of Triticum aestivum Genotypes to Fusarium graminearum and effects on Traits Related to Grain Yield and Seed Quality
… FHB research are dedicated to incorporating FHB resistance into adapted wheat lines. While this is a prudent method of combating this disease, this process will take many years to complete. We have examined all FHB assessment parameters, which include FHB incidence, FHB severity, FHB index, …

Non-target-site resistance to ALS inhibitors in waterhemp
… cropping region. The evolution of herbicide resistance and multiple resistance mechanisms within the species is one of the major properties making it difficult to control, and ALS-resistant waterhemp populations have been found and studied considerably. A waterhemp population (designated MCR) …

Stationary Exercise Bicycle Instrumentation and Verification of OpenSim Pelvic Residual Loads in Seated Cycling
… OpenSim. Five participants cycled at a moderate resistance level for three trials. Force and moment data were collected by seat, handlebar, and pedal load cells, while kinematic data were collected by an optical motion capture system. Participant data were analyzed with the OpenSim residual …

Characterizing resistance of Erysiphe necator to fungicides belonging to the quinone outside inhibitors and demethylation inhibitors
Practical resistance of Erysiphe necator to quinone outside inhibitors (QoIs) is now widespread, and resistance to demethylation inhibitors (DMIs) has also developed. The goal of this research was to characterize fungicide resistance by elucidating resistance mechanisms and determining its …

Validation of the ‘Victim Empathy Response Assessment (ii)’ (VERA-ii) with a Non-offending Adult Male Community Sample
… providing physiological measurements of skin resistance level (SRL) and heart rate (HR). Following this they completed the VERA(ii) cognitive and affective empathy questionnaires, also the Wechsler Abbreviated Scale of Intelligence, Eysenck Personality Questionnaire Revised - Short Form, …

Ultra-wideband technology for short-range wireless communication
… impulse-based radio UWB signals. We study jam resistance and capacity of UWB. Jam resistance is analyzed for binary pulse position modulation (PPM) with the interference being modeled as correlated Gaussian. Closed-form expressions are provided for the jam resistance of a PPM UWB system …

Identification of quantitative trait loci, candidate genes and diagnostic markers for Hessian fly resistance in wheat
… approach for HF management. Although over 50 HF resistance (H) genes and quantitative trait loci (QTL) have been reported, only a few of them have been deployed in limited areas due to their loss of effectiveness against predominant HF biotypes, and lack of diagnostic markers for breeding …

The ecology and evolutionary history of the Deinococcaceae family
… approximately 3000 times more radiation resistance capability than humans and 50 times more than Escherichia coli. The remarkable radiation resistance phenotype in D. radiodurans and certain members of this family has established the conventional belief that radiation resistance is the …

A waterhemp saga: Seed production, genetics, hybridization, and the creation and discovery of quad-stack individuals
… of this species is its propensity to evolve resistance to herbicides—a feat which it has now accomplished for herbicides with four different modes of action, with the evolution of resistance to other herbicide modes of action expected in the future. Options for chemical control of this …

Evaluation of an inoculation method and quantitative trait loci for fusarium head blight resistance in wheat
… to identify quantitative trait loci (QTL) for resistance to FHB traits in the resistant line IL97-1828. Resistance to FHB in IL97-1828 is independent of the well characterized and widely used Asian sources. A population consisting of 242 wheat recombinant inbred lines (RILs), developed from a …

Hedging against exporting costs and risks in the South African extractive industry
The revolutionisation of international economies and monetary systems has been taking place since the early 1970s. This occurred due to the diminishing fixed exchange rate systems of, initially, the Gold Standard and subsequently the Bretton Woods System. The collapse of these systems, especially …

Breeding for resistance to clover rot (Sclerotinia spp.) in red clover breeding (Trifolium pratense)
… dependent on weather conditions. Moreover, resistance breeding is hampered by the lack of useable bio-tests and by the lack of knowledge on the genetic and phenotypic variation among Sclerotinia isolates. In this context, the objectives of this thesis were to analyse the phenotypic and …
