Production of biochar is accomplished by pyrolysis corncobs at 350 °C (BC-350) and 450 (BC-450) under oxygen-limited conditions. The chemical physical properties were investigated via XRD, FTIR, BET, SEM EDX analysis. Batch experiments conducted for the adsorption Pb2+ ions from aqueous solution onto with regards to pH, contact time, dose initial concentration. efficiency was increased as incre...

Backround: Helicoverpa armigera is major maize pest, while Conopomorpha cramerella cocoa main insect pest. Their larvaes lie in corn cob and pulp which can be controlled using egg parasitoids. Methods: Exploring H. eggs on female flowers a plant along the 50 m line at 10 points with 4 distance to obtain C. cramrella. Egg parasitoids were obtained by taking from cacao pod, Corcyra cephalonica tr...

Current corn kernel-cob bonding mechanics models (LSD models) uniformly consider the force changes during maize threshing operation as an elastic change, resulting in computational errors of up to 10% or more discrete element simulations. Due inability perform high-precision simulation characteristics operation, core operating parameters thresher (rotation speed component) rely mainly on empiri...

Coordinated functioning of the cob and florets of the maize ear confers grain yield. The cob is critical for carbon partitioning and assimilated nitrogen (N) supply for grain development. However, molecular recognition of the cob and peripheral florets, characterization of genes mediating translocation of N assimilates, and responses of these two tissues to low N (LN) remain elusive. Transcript...

Salmonella enterica degrades 1,2-propanediol (1,2-PD) by a pathway that requires coenzyme B(12) (adenosylcobalamin; AdoCbl). The genes specifically involved in 1,2-PD utilization (pdu) are found in a large contiguous cluster, the pdu locus. Earlier studies have indicated that this locus includes genes for the conversion of vitamin B(12) (cyanocobalamin; CNCbl) to AdoCbl and that the pduO gene e...

Four Thai - rumen fistulated male swamp buffaloes (Bubalus bubalis), about four years old with 400±20 kg liveweight, were randomly assigned according to a 4×4 Latin square design to receive dietary treatments. The treatments were: ground corn cob (GCC) replacement for cassava chip (CC) in concentrate at 0% (T1); GCC replacement at 33% (T2); GCC replacement at 67% (T3); and GCC replacement at 10...

Microbial extraction of nickel from lateritic chromite overburden (COB), Sukinda by Acidithiobacillus ferrooxidans has been investigated in this work. In anoxic environment, A. ferrooxidans reduced the ferric iron in goethite [Fe(O)OH] mineral of COB by using elemental sulphur as electron donor. Nickel embedded in the complex goethite matrix of COB was successfully recovered by cumulative actio...

The objective of this work was to evaluate in a batch system the effect temperature, adsorbent dose and particle size elimination Cadmium (II) ions using corn cob (Zea mays). A central 22 star composite type experimental design used. From characterization bio-adsorbent by Fourier Transform Infrared Spectroscopy (FTIR), it found that its structure has OH, COOH, methyl amino groups, intervening p...
