This study examined the ability of two biochars converted from anaerobically digested biomass to sorb heavy metals using a range of laboratory sorption and characterization experiments. Initial evaluation of DAWC (digested dairy waste biochar) and DWSBC (digested whole sugar beet biochar) showed that both biochars were effective in removing a mixture of four heavy metals (Pb(2 +), Cu(2+), Ni(2+...

The efficacy of transgenic cotton genotypes containing Cry1Ac, Cry1F, and Cry1Ac stacked with Cry1F (WideStrike®, Dow Agrosciences, Indianapolis, IN) were investigated during 2001-2003 against the beet armyworm, Spodoptera exigua (Hübner) (=BAW), and the fall armyworm, Spodoptera frugiperda (J. E. Smith) (=FAW), in laboratory bioassays and small experimental field plots. In all experiments, cot...

Research and Marketing Act funds have been allotted to the Western Regional Research Laboratory for work on the technology of sugar beets. Liaison between the Laboratory and industry has been established through the Committee on processing problems, appointed by the industry. This committe has met at the Laboratory to discuss subjects meriting investigation and has proposed four problems: (1) s...

Fluctuations in the natural environment introduce variability into the biological systems that exist within them. In this paper, we develop a model for the influence of random fluctuations in the environment on a simple epidemiological system. The model describes the infection of a dynamic host population by an environmentally sensitive pathogen and is based on the infection of sugar beet plant...

Three new grayanane diterpenoids, pierisoids C‒E (1-3), as well as 10 known ones (4-13), were evaluated from the flowers of Pieris formosa, which is used as an insecticide in rural areas of China. Their structures were elucidated on the basis of extensive 1D and 2D NMR spectroscopic data analyses. Significant antifeedant activity of 1, 3 and 10 against the beet armyworm (Spodoptera exigua) was ...

The aim of this study is to investigate the application ultrasound in extraction betanin from beets (Beta vulgaris) using Deep eutectic solvents (DES). process was optimized response surface methodology. time variable found be correlated with performance. Three DES (choline chloride: urea (CC:U), choline glycerol (CC:G), and citric acid (CC:Ac)) were studied. concentration extracted CC:U, CC:G,...

The human intake of selenium (Se), which is an essential element in animals and humans, can be increased through the consumption vegetables that have been biofortified during cultivation. There increasing interest wild edible plants (WEPs) due to their positive effects on health. In fact, many WEPs are rich microelements, vitamins, dietary fibers, several antioxidant compounds. Among WEPs, sea ...
