The microbiologic reduction of a 0.2 to 2.0 mm size fraction of an Atlantic coastal plain sediment (Eatontown) was investigated using a dissimilatory Fe(III)-reducing bacterium (Shewanella putrefaciens, strain CN32) to evaluate mineralogic controls on the rate and extent of Fe(III) reduction and the resulting distribution of biogenic Fe(II). Mössbauer spectroscopy and X-ray diffraction (XRD) we...

The current study was conducted to investigate the effects of dietary iron-loaded chitooligosacharide nanoparticles (Fe-CNP) on occurrence of bacterial chondronecrosis with osteomyelitis (BCO) in broiler chickens. Four hundred eighty day-old chicks (Ross 308) were assigned to four treatments with six replicates of 20 birds. All chicks were reared on wire flooring system up to 42 days of age. Th...

the aim of this study was to determine the most suitable shaking frequency and amplitude for shake harvesting esfahan's edible fig (ficus carica cv. sabz). a hand held limb shaker with adjustable shaking frequency and amplitude was used for this study. a 3x3 factorial experiment with three levels of oscillating frequency (10, 12 and 14 hz) and three levels of shaking amplitude (20, 32.5 and 45 ...

The purpose of this presentation is to outline the Museum Multimedia (MM) experience in Russia. I am quite not sure wether all my colleagues experts and museum community in West Europe and America are intimately familiar with Russian experience in this sphere and I am pleased to have this opportunity to fill the gap. I will mainly focus on the general picture for some more reports with detailed...

BACKGROUND Lateral clavicle fractures have been reported after coracoclavicular (CC) ligament reconstructions with bone tunnels through the clavicle. PURPOSE To biomechanically compare clavicle strength following 2 common CC reconstruction techniques with different bone tunnel diameters. STUDY DESIGN Controlled laboratory study. METHODS Testing was performed on 2 groups of matched-pair ca...

The application of the photo-Fenton process for the treatment of wastewaters contaminated with diesel oil was investigated. This particular process has been widely studied for the photochemical degradation of highly toxic organic pollutants. Experiments were performed according to a factorial experimental design at two levels and two variables: H(2)O(2) concentration (5-200 mM) and Fe(2+) conce...

We examined the chemical reactions influencing dissolved concentrations, speciation, and transport of naturally occurring arsenic ~As! in a shallow, sand and gravel aquifer with distinct geochemical zones resulting from land disposal of dilute sewage effluent. The principal geochemical zones were: ~1! the uncontaminated zone above the sewage plume @350 mM dissolved oxygen ~DO!, pH 5.9#; ~2! the...

Nanoparticles of Fe(3)O(4) were synthesized by hydrolysis in an aqueous solution containing ferrous and ferric salts at various ratios with 1,6-hexanediamine as a base. It was found that the ferrous to ferric ratio influences the reaction mechanism for the formation of Fe(3)O(4). When the ratio of ferrous to ferric ions was increased, the formation of large hydroxide particles as a precursor of...

the experiment was investigated to survey of yield and yield components of sunflower cultivars under drought stress in 2012 in kabootatabad of esfahan farm. an experiment was conducted in split plot and was designed in randomized complete block with three replications. irrigation was as main plots in 3 levels (control (normal irrigation), irrigation of 130 mm evaporation from pan evaporation, i...
