The gibberellin content of pea seeds developing in excised pea pods cultured on a medium containing the plant growth retardant AMO-1618 was reduced in comparison with pea seeds cultured on retardant-free medium. The reduction increased with increasing concentrations of AMO-1618. However, at the lowest concentration tested (5 milligrams per liter) the growth of the seeds was not affected whereas...

Terahertz (THz) time-domain spectroscopy (TDS) imaging is considered a nondestructive evaluation method for composite materials used for examining various defects of carbon fiber reinforced polymer (CFRP) composites and fire-retardant coatings in the reflective imaging modality. We demonstrate that hidden defects simulated by Teflon artificial inserts are imaged clearly in the perpendicular pol...

fe3o4 nanoparticles were synthesizedviaa simple chemical reaction between fecl2.4h2o and fe(no3)3.9h2o under nitrogen atmosphere at room temperature, and then nanoparticles were added to cellulose acetate (ca) polymer. the influence of nanoparticles on the thermal properties of ca polymeric matrix was studied using thermogravimetric analysis (tga). nanostructures were characterized by x-ray dif...

The intumescent retardant coating was fabricated by a combination of epoxy binder and flame-retardant ingredients for the steel plate. This paper investigates influence nanoclay content on improving fire properties fire-retardant coatings. performances coatings were determined test at 950oC one hour. degradation characterized Thermal gravimetric analysis (TGA). morphology, composition char stud...

Mycobacterium tuberculosis possesses six genes (Rv0516c, Rv1364c, Rv1365c, Rv1904, Rv2638 and Rv3687c) encoding putative anti-sigma factor antagonists or stress signaling molecules (SSMs). We have previously shown that the products of these genes physically interact between themselves and with sigma factor SigF (encoded by Rv3286c) and anti-sigma factor RsbW (encoded by Rv3287c) in the yeast tw...

In this study, Flake-like magnesium hydroxide (Mg(OH)2) and cubic-like aluminum hydroxide (Al(OH)3) nanostructures were synthesized via a simple co-precipitation method at relatively low temperature. Chemical properties and surface morphology of the magnesium hydroxide and aluminum hydroxide were characterized by X-ray diffraction analysis (XRD), scanning electron microscopy image (SEM), transm...

BACKGROUND Children are exposed to flame retardants from the built environment. Brominated diphenyl ethers (BDE) and organophosphate-based flame retardants (OPFRs) are associated with poorer neurocognitive functioning in children. Less is known, however, about the association between these classes of compounds and children's emotional and social behaviors. The objective of this study was to det...

BACKGROUND Organophospate flame retardants (PFRs) are chemicals of emerging concern due to restrictions on polybrominated diphenyl ether flame retardant formulations. We describe the occurrence, variability, and predictors of urinary metabolites of PFRs among pregnant women. METHODS In 2014-2015, 59 women from Providence, RI provided up to 3 spot urine samples during pregnancy (~12, 28, and 3...

We investigate the uniformity of anti-plane stresses inside two interacting p-Laplacian nonlinear elastic non-elliptical inhomogeneities embedded in an infinite linear matrix subjected to uniform remote stresses. In our discussion, have a common shear modulus. The internal is accomplished through numerical solution single non-linear equation.
