EVALUATION OF FUNGICIDE APPLICATION AT LATE BLOOM FOR THE CONTROL OF SCLEROTINIA STEM ROT IN RAPESEED (CANOLA)
… to warrant collection and analysis of disease incidence data at 4 of 5 locations in 1987 and 5 of 10 locations in 1988. Late bloom application of benomyl at the recommended rate (0.6 kg a.i./ha) significantly reduced disease incidence compared to the check in all tests except one. In four …

Validating Forecasting Strategies of Simple Epidemic Models on the 2015-2016 Zika Epidemic
… forecasts of simple epidemic models. We use incidence data from the 2015-2016 Zika virus outbreak in Antioquia, Colombia, to assess what model features result in accurate forecasts. We employed the Parametric Bootstrapping and Ensemble Kalman Filter methods to assimilate data and then …

Increasing incidence of cancer of the corpus uteri in the elderly in Canada? Analysis of descriptive data, hysterectomy adjustment and chart review.
Incidence of cancer of the corpus uteri (of which 89% is endometrial adenocarcinoma) in Canada is declining in women under 70 years of age; in women 70 and over incidence increased from 1969 until 1982 since when it has been stable. These incidence data use as a denominator all women in the …

Fitting Stochastic Epidemic Models to Multiple Data Types
… epidemics models to surveillance case count data. Recently, researchers began to make use of infectious disease agent genetic data to complement statistical analyses of case count data. Such genetic analyses rely on the field of phylodynamics --- a set of population genetics tools that aim at …

Vegetarian Dietary Patterns: Mortality, Colorectal Cancer, and Food Consumption
… these outcomes (mortality and colorectal cancer incidence) in a large North-American cohort. We also sought to further characterize potentially important differences in the food consumption patterns of these diets. Design Baseline diet was measured by a quantitative food frequency questionnaire …

Comparison of Potential Salmonella Portals of Entry and Tissue Distribution Following Challenge of Poultry
… to the hypothesis. Both the cecal CFU recovery data and organ invasion incidence data from these experiments provided evidence for the subsequent fate of Salmonella exposed to the respiratory system, potentially involving a systemic route. Overall, our data suggests that the respiratory route …
