Prohexadione-calcium (Pro-Ca) is a recently developed plant growth retardant used in some fruit trees. However, it important that the reduction of vegetative shoot dose not decrease yield and quality. In this study, effects Pro-Ca applications on quality Monroe peach, growing vigor rootstock (GF 677) were investigated. For reason, trees sprayed twice with 0 (water + surfactant), 62.5, 125, 250 ...

Hydromagnesite occurrences in British Columbia have been recognized since the beginning of the 19th century (Reinecke, 1920; Young, 1915). However, the known occurrences of hydromagnesite are too small to compete with the large sparry magnesite deposits in British Columbia (Grant, 1987; Simandl et al., 1996 a,b and Simandl, 2000) as potential sources of raw materials for the production of indus...

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...

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...
