deploying an unmanned aerial vehicle (uav) equipped with a multispectral sensor for detecting between differing levels of barley (h vulgare l.) fungal diseases in northern ontario
(2017)to date, no studies exist exploring the multispectral detection of fungal diseases in barley (h vulgare l.) with uav imagery. the purpose of this work was to determine if the spectral response (vi) of barley fungicide ... -
diatoms as an indicator of pharmaceutical contamination in a freshwater system
(2018)historically, microalgae have been used as bio-indicators of aquatic health and this can be seen in several studies across the world. often at the bottom of the food chain, microalgae constitute the primary producer of ... -
exploring older adult male participation in a free, biweekly, group-based, indoor walking initiative
(2018)aging is an inevitable part of life that ushers individuals across the life course (bryant, corbett, & kutner, 2001; kirk-sanchez & mcgough, 2013; song & kong, 2015). the chronological age of 65 is mainly associated with ... -
habitat selection in the common five-lined skink near the northern extent of its range
(2016)the study of habitat selection is vital to identify potential threats and to conserve species at risk. the consequences of living in a particular habitat can influence processes beyond the individual with observable effects ... -
increased production of cellulosic sugars from lignocellulosic materials
(2018)renewable energy is energy that is regenerated naturally for infinite time. renewable energy can be categorized into solar, hydro, wind, geothermal, and biomass. biomass is an organic material such as agricultural, forest ... -
