Twelve isolates of Trichoderma (six of T. harzianum, five of T. viride, one of T. virens), which reduced variably the incidence of collar rot disease caused in peanut by Aspergillus niger Van Tieghem, were evaluated for their potential to produce lytic enzymes during in vitro antagonism. T. viride 60 inhibited highest (86.2%) growth of test fungus followed by T. harzianum 2J (80.4%) at 6 days a...
SUMMARY The production of pol ygalacturonase in associations of nodule bacteria and seedlings of leguminous plants was investigated. Plants and bacteria were combined in the following ways : (a) different plant species were combined with infective strains (isolated from the same cross inoculation group) as well as non-infective ones (from foreign groups) ; (b) host plant species with different ...
In this research, water equivalent ratios (WER) at helium ion beam energy ranging 25-250 MeV/u for four potential plastic dosimetric materials: polycarbonate (PC), polypropylene (PP), polymethyl methacrylate (PMMA), and paraffin have been calculated using MCNPX Monte Carlo code. Among studied materials, PC and PP with 0.979 and 1.177 show minimum and maximum differences with water respectively....
Activities and Findings Research and Education Activities: The research carried out involved the synthesis of platinum nanoparticles of different sizes and shapes and capped with PVP or other polymers such as polymethyl acrylates. TEM was used to determine the size and shape distributions and their changes during their catalytic activity in colloidal solutions.. Two reactions were studied. A ge...
Neurophysiological recording in alert monkeys requires the creation of a permanent aperture in the skull for repeated insertion of microelectrodes. Most laboratories use polymethyl methacrylate to attach a recording chamber over the skull opening. Here, we describe a titanium chamber that fastens to the skull with screws, using no polymethyl methacrylate. The gap between the base of the chamber...
Restorations in dentistry must reproduce the aspect of patient’s natural teeth and require non-toxicity, biocompatibility, good mechanical properties order to last longer. are permanently contact with microbes that can adhere form biofilms. The purpose this study was determine adhesion extent Streptococcus mutans polymethyl methacrylate (PMMA) resin base containing TiO2 nanoparticles. To unders...
As interest in using carbon nanotubes for developing biologically compatible systems continues to grow, biological inspiration is stimulating new directions for in vivo approaches. The ability to integrate nanotechnology-based systems in the body will provide greater successes if the implanted material is made to mimic elements of the biological milieu especially through tuning physical and che...
