Field reaction of 25 red mottled bean ( Phaseolus vulgaris L.) genotypes to common bacterial blight [Xanthomonas campestris pv. phaseoli (Smith) Dye] was evaluated in Puerto Rico over 2 years. The average disease severity (percent leaf area with symptoms) was similar over years. The determinate red mottled genotypes had almost twice as much disease as indeterminate genotypes. Eight of the indet...

This paper focuses on the investment plan with maximum return around fluctuation of stock market. First 
 all, this is based neural network model price trend line, and then uses reverse Bollinger band strategy (CBB model). We calculate error forecast, draw residual diagram, find that level prediction within an acceptable range. The in has strong expansibility good robustness. Finally, we s...

While mechanisms of different carbon dioxide (CO2 ) assimilation pathways in chemolithoautotrohic prokaryotes are well understood for many isolates under laboratory conditions, the ecological significance of diverse CO2 fixation strategies in the environment is mostly unexplored. Six stratified freshwater lakes were chosen to study the distribution and diversity of the Calvin-Benson-Bassham (CB...
