Through this work, a carbon network/aluminum matrix porous composite material was analyzed for its susceptibility to material degradation in sulfuric acid and seawater corrosive media.Simple potentiodynamic electrochemical testing was implemented, and from polarization curves, the Tafel coefficients and exchange current densities were obtained for
The potential of Euglossini bees, especially Euglossa, as biological indicators of organic vs non-organic coffee farms was studied in Atenas and San Isidro, Magnesium Alajuela, Costa Rica using 1.8-cineole as lure.Observations were made for three days at each of four farms and complemented with data from a year of observations.Orchid bees were in g
Objective The existing target speed planning algorithm for the automatic driving of urban rail transit train cannot handle in real time the temporary change of Folic Acid/ Vitamin B-9 the line speed limit in case of emergency due to the large computational load and long computation time.With regard to the problem, a real-time target speed planning
