A low glucosinolate content (21.8 mmol g) Brassica napus seed meal (RSM) applied to orchard soils altered communities of both pathogenic and saprophytic soil micro-organisms. RSM amendment reduced infection by native and introduced isolates of Rhizoctonia spp. and recovery of Pratylenchus spp. from apple roots. Root infection by Rhizoctonia solani AG-5 was also suppressed in split-root assays w...

Zinc oxide and Ga-doped ZnO nanowires and nanorods are synthesized on various substrate like Fluorine doped tin oxide glass plate, SiO2 coated Silicon substrate and aluminum nitride coated silicon substrates. The coating process carried out using zinc oxide sol-gel solution. The synthesized material was characterized using XRD (X-ray diffraction), FE-SEM (Field emission scanning electron micros...

background : in medical studies, when the joint prediction about occurrence of two events should be anticipated, a statistical bivariate model is used. due to the limitations of usual statistical models, other methods such as artificial neural network (ann) and hybrid models could be used. in this paper, we propose a hybrid artificial neural network-genetic algorithm (ann-ga) model to predictio...

of aluminum oxide, that emitted a deep red-colored beam. After this invention, dental researchers started investigating the various potentials of lasers. In 1965, Stern and Sognnaes reported that a ruby laser could vaporize enamel and had thermal effects on the dental pulp. In 1970’s, researchers began to find the clinical oral soft tissue uses of medical CO2 and neodymiumdoped:yttrium aluminum...

introduction: the aim of this study was to assess shear bond strength of composite to dentin after air abrasion and laser treatment. methods: 40 human extracted molars divided into 4 groups (n=10) received the following treatments. group 1: carbide bur, group 2: air abrasion with aluminum oxide 50 μm, group 3: irradiated with erbium-doped yttrium aluminum garnet (er: yag) laser (150 mj/20hz), g...

in this paper, we present an application of evolved neural networks using a real coded genetic algorithm for simulations of monthly groundwater levels in a coastal aquifer located in the shabestar plain, iran. after initializing the model with groundwater elevations observed at a given time, the developed hybrid genetic algorithm-back propagation (ga-bp) should be able to reproduce groundwater ...

Single-crystal aluminum-gallium oxide films have been grown by molecular beam epitaxy in the corundum phase. Films of the (Al(1-x)Ga(x))(2)O(3) alloys doped with neodymium have favorable properties for solid-state waveguide lasers, including a high-thermal-conductivity sapphire substrate and a dominant emission peak in the 1090-1096 nm wavelength range. The peak position is linearly correlated ...

Water pollution due to dyes from industrial effluents and domestic wastewater is a big environmental issue, so an effective adsorbent needed. In this study, graphene oxide/chitosan (GO/CS) composites were synthesized applied for methylene blue (MB) dye removal. Characterization was done on the GO GO/CS using FTIR, EDX, SEM, TGA. The adsorption studies conducted verify effect of pH, dosage conta...
