Definition of Agrostis palustris leaf health at the time of infection and colonization by Curvularia lunata
The state of leaf health of intact Penneagle creeping bentgrass leaves into which Curvularia lunata was able to ingress was determined by reducing cuticle/wax formation with trichloroacetic acid (TCA) and stressing plants with high air temperatures. Plants were grown until the third leaf had fully …

Epidemiology, Aphid Vectors, Impact and Management of Tobacco Etch Potyvirus in Hot Peppers in Jamaica
Production of hot peppers, Capsicum spp., in Jamaica is constrained by the aphid-transmitted potyviruses, tobacco etch virus (TEV) and potato virus Y (PVY). The virus epidemiology was not understood and no effective virus management system existed for these viruses. This study sought to identify …

Process Intensification of Spodoptera frugiperda (Sf) Cell Growth via Multi-Parallel Bioreactor System
The objective of this project is to improve the yield of the fed-batch manufacturing process for the production of Flublok influenza vaccine, which was approved by the FDA in 2018. In short, Spodoptera frugiperda (SF+) insect cells are grown to a specific target cell density and then infected with …

Determination of cell fate selection during phage lambda Infection
Bacteriophage lambda infection of Escherichia coli can result in distinct cell fate outcomes: for example, some cells lyse while others survive as lysogens. A quantitative molecular model of lambda infection supports the hypothesis that spontaneous differences in the timing of individual molecular …

Impact of Mosquito Age and Insecticide Exposure on Vector Competence of Aedes albopictus (Diptera: Culicidae) for Zika Virus
… temperature). A mosquito's chronological age at time of infection may impact its immune response against virus infection. There are no effective vaccines for most arboviruses, including ZIKV, hence insecticides are the best defense against mosquito transmitted ZIKV. Aedes albopictus is difficult …

Methods: This study used Interpretive Descriptive methodology to explore the experiences of Asian Canadian adolescents who have had COVID-19 through one-on-one interviews virtually and in person. Prior to the interview, participants …

Environmental, Landscape, and Host-Related Factors Associated With Parasitism and Its Effects on Larvae and Metamorphic Frogs of Rana Pipiens
The emergence of several diseases affecting amphibian populations worldwide has prompted investigations into factors that determine the distribution and abundance of parasites in frogs. Environmental and land use determinants of the structure of parasite communities of metamorphic frogs of Rana …

Assessing the Distribution and Impact of <I>Bean pod mottle virus</I> (BPMV) as a Re-emerging Virus, and <I>Soybean mosaic virus </I>(SMV) in Soybean Grown in Virginia
… has increased in many soybean growing areas of Virginia and the USA in general. From 1997 to 2001, a total of five BPMV isolates (V-W1, V-W2, V-S98-1, V-S98-15 and V-S01-10) were collected in Virginia and characterized. In this study, the effects of these isolates were studied, alone or with …

EVALUATION OF FUNGICIDE APPLICATION AT LATE BLOOM FOR THE CONTROL OF SCLEROTINIA STEM ROT IN RAPESEED (CANOLA)
… foliar fungicides for the control of sclerotinia stem rot in rapeseed should be applied at early or full bloom but not at late bloom. Field experiments were conducted in several areas of Saskatchewan in 1987 and 1988 to determine if spraying with benomyl at late bloom could …

A prospective investigation of cognitive-behavioural models of irritable bowel and chronic fatigue syndromes: implications for theory, classification and treatment
The purpose of this study was to prospectively evaluate the application of the cognitivebehavioural model to two common functional somatic syndromes: irritable bowel syndrome (IBS) and chronic fatigue syndrome (CFS). A range of predisposing, precipitating and perpetuating variables operationalised …

Network-based advanced malware detection using multi-classifier machine learning
… Malware has been the primary choice of weapon to carry out various cyberattacks. Host-based malware detection, as the primary line of defence, evolved into the \Achilles Heel". In particular, the increase of security-aware targeted attacks, comprises of reconnaissance and delivery …
