An agricultural waste (walnut shell) was undertaken to remove Cu(II) from aqueous solutions in batch and continuous fluidized bed processes. Walnut shell found be effective reaching 75.55% at 20 200 rpm, when pH of the solution adjusted 7. The equilibrium achieved after 6 h contacting time. maximum uptake 11.94mg/g. isotherm models indicated that highest determination coefficient belongs Langmu...

The antifungal activity of scallop-shell powder heated at 1000 degrees C for 1 h against Trichophyton was kinetically investigated and the possibility of applying the powder to the treatment of dermatophytosis was examined. The death rate of T. mentagrophytes NBRC5466 in the heated shell powder slurry increased with powder concentration, following first-order reaction kinetics. Elevated slurry ...

this study was carried out to investigate the important characteristics in some cultivars/genotypes of persianwalnut (juglans regia l.), black walnut (j. nigra l.), and walnut inter-specific hybrids: paradox (j. hindsii × j.regia) and royal (j. hindsii × j. nigra) in kamalshahr research station in karaj in 2011-2012. in the study,vegetative vigor was evaluated based on trunk cross-sectional are...

Accepted: May 25, 2011; Published: August 30, 2011 Abstract The adsorption and transformation of K2Cr2O7 at natural hermit crab shell powder was studied by UV-visible spectrophotometry. K2Cr2O7 is adsorbed at natural hermit crab shell powder, and follows the Freundlich adsorption model with the adsorption constant of KF=888.8 and adsorption free energy change of 16.83 kJ.mol . The adsorbed K2Cr...

Title of Dissertation: ADVANCED IMAGING AND DATA MINING TECHNOLOGIES FOR MEDICAL AND FOOD SAFETY APPLICATIONS Lu Jiang, Doctor of Philosophy, 2009 Dissertation Directed By: Professor Yang Tao, the Fischell Department of Bioengineering As one of the most fast-developing research areas, biological imaging and image analysis receive more and more attentions, and have been already widely applied in...

The black walnut, Junglas nigra, is indigenous to eastern North America, and abscission of its fruit occurs around October. The fruit consists of a husk, a hard shell, and kernel. The husk is commonly discarded in processing, though it contains phenolic compounds that exhibit antioxidant and antimicrobial properties. For this study, black walnut husks were extracted using supercritical carbon d...

The present environmental condition indicates the immediate need for sustainable materials containing mainly natural elements composite fabrication. Encouragement of fibers in can significantly reduce greenhouse effect and high cost manufacturing synthetic fiber-based polymer composites. Hence, this study aimed to investigate physio-mechanical properties banana fiber (BF) -based epoxy (EP) comp...
