Over the years, numerous studies have been conducted on integration of computer vision and machine learning in plant disease detection. However, these conventional methods often require contour segmentation infected region from entire leaf manual extraction different discriminative features before classification models can be developed. In this study, deep models, specifically, AlexNet convolut...

Foraging in the Black Lion Tamarin (L. chrysopygus Mikan, 1823) was observed in the Caetetus Ecological Station, São Paulo, southeastern Brazil, during 83 days between November 1988 to October 1990. These tamarins use manipuJative, specitic-site foraging behavior. When searching for animal prey items, they examine a variety ofmicrohabitats (dry palm leaves, twigs, under loose bark, in tree cavi...

BACKGROUND Tropical peat swamp forests (TPSF) are globally significant carbon stores, sequestering carbon mainly as phenolic polymers and phenolic compounds (particularly as lignin and its derivatives) in peat layers, in plants, and in the acidic blackwaters. Previous studies show that TPSF plants have particularly high levels of phenolic compounds which inhibit the decomposition of organic mat...

Date palm plantlets derived from tissue culture suffer from slow rate of growth. Large sizes, of such plantlets, are also sold for higher price. Thus, producers and growers are demanding a method to stimulate the growth rate of these plantlets regenerated by tissue culture. In this study, gibberellic acid was applied alone at 100 ppm or informulations at 50 ppm. Phosphoric acid at 1%, v,v and u...
