Development of new tools and germplasms for improvement of wheat resistance to Fusarium head blight
… spikelets (PSS), Fusarium damaged kernels (FDK) and deoxynivalenol (DON), a toxin produced by the pathogen. Genome-wide association studies (GWAS) identified significant trait associations with single nucleotide polymorphisms (SNPs) on chromosomes 1A, 1D, 2B, 3A, 3B, 4A, 5B and 5D. These …

A Comparison of Full-Day and Half-Day English and French Immersion Kindergarten: Children's Outcomes and Experiences
… children from English full-day kindergarten (FDK) scoring significantly higher at the beginning of Grade 1 than children in either FI program, and English word decoding, with only children from half-day programs (FI and English) making significant gains over the kindergarten year. However, …

Quantitative Trait Loci for Resistance to Fusarium Head Blight in the Hulless Winter Barley Cultivar Eve
… FHB severity (Sev), Fusarium damaged kernels (FDK), and deoxynivalenol (DON) were assessed over 2014-15 and 2015-16 at Blacksburg, VA, Mount Holly, VA, Kinston, NC, and Lexington, KY. A QTL on chromosome 6H associated with FHB Sev, FDK, and DON was identified. The QTL accounted for as high as …

ENHANCING SUSTAINABLE FEED PRODUCTION: UTILIZING AGRICULTURAL WASTES AS SUBSTRATES FOR BLACK SOLDIER FLY LARVAE CULTIVATION
… utilization of Fusarium-damaged wheat kernels (FDK) as a feed substrate for BSFL. FDK, typically unsuitable for human or animal consumption due to the presence of harmful mycotoxins such as deoxynivalenol (DON), was hypothesized to support BSFL growth without adverse effects on feeding behaviour …

Assessment and Reaction of Triticum aestivum Genotypes to Fusarium graminearum and effects on Traits Related to Grain Yield and Seed Quality
… percentage fusarium damaged kernels (percentage FDK), and 15-acetyl deoxynivalenol toxin (DON toxin) accumulation, to ascertain which assessment parameters best quantify FHB resistance levels in addition to grain yield and grain volume weight (GVW) losses. FHB index provides the most reliable …

Evaluation of an inoculation method and quantitative trait loci for fusarium head blight resistance in wheat
… severity, FHB index, Fusarium damage kernels (FDK) percentage, DON concentration, and ISK index, which is a disease index that incorporates disease incidence, severity, and % FDK. Significantly less disease incidence was observed in 2009 than at both locations in 2010, and significantly lower …

Applications of cone beam computed tomography in radiotherapy treatment planning.
… part, the conventional Feldkamp-Davis-Kress (FDK) cone-beam reconstruction algorithm was implemented in Matlab. The algorithm was then modified using weighting factors for data redundancy and for nonequal cone angles. A 2D adaptive filter was used to remove noise and to compensate for the loss …

Application and Development of Algebraic Reconstruction Algorithms for High Dose Rate Brachytherapy Gel Dosimetry with Optical Computed Tomography Readout
… when using the standard Feldkamp-Davis-Kress (FDK) reconstruction algorithm. This work then investigated using the Ordered Subsets Convex algorithm with Total Variation minimization regularization (OSC-TV) instead of the FDK algorithm to suppress the artifacts. Three variants of the OSC-TV …

WAVELENGTH AND VISUAL FEATURE SELECTION FOR NON-DESTRUCTIVE EVALUATION OF FUSARIUM HEAD BLIGHT IN WHEAT USING HYPERSPECTRAL IMAGING
Fusarium head blight (FHB) is a fungal disease affecting the heads of cereal crops and has caused significant economic losses in the Canadian prairie wheat industry. Although wheat breeding efforts to enhance resistance genes are ongoing, efficient and accurate detection of FHB remains critical for …
