The middle temporal complex (MT/MST) is a brain region specialized for the perception of motion in the visual modality. However, this specialization is modified by visual experience: after long-standing blindness, MT/MST responds to sound. Recent evidence also suggests that the auditory response of MT/MST is selective for motion. The developmental time course of this plasticity is not known. To...

2,4,6-triisopropylstryrene was synthesized in a single step via the witting reaction from the corresponding aldehyde. the reaction of three styrene's derivatives, 2,6-dimethylstyrene, 2,4,6-trimethylstyrene, and 2,4,6- triisopropylstyrene with 4-methyl-l,2,4-triazoline-3,5-dion(m etd) was investigated. these reactions are instantaneous at room temperature and lead to the formation of 2: 1 ...

Styrene oxide and 2-phenylethanol metabolism in the styrene-degrading Xanthobacter sp. strain 124X was shown to proceed via phenylacetaldehyde and phenylacetic acid. In cell extracts 2-phenylethanol was oxidized by a phenazine methosulfate-dependent enzyme, probably a pyrroloquinoline quinone enzyme. Xanthobacter sp. strain 124X also contains a novel enzymatic activity designated as styrene oxi...

k-ary m-way networks are especially suitable for broadcasting because of the shared nature of m-way channels. A flit placed on an m-way channel can be accepted concurrently by adjacent routers and node interfaces during a given clock cycle. This paper discusses two modified Minimum Spanning Tree (MST) broadcast algorithms that are designed to work efficiently in k-ary mway networks. The algorit...

Styrene is widely used as one of the most important industrial materials for the production of synthetic rubbers, plastic, insulation, fiberglass, and automobile parts. Inhaled styrene has been reported to produce respiratory toxicity in humans and animals. Styrene oxide, a reactive metabolite of styrene formed via cytochrome P450 enzymes, has been reported to form covalent bonds with proteins,...

Background: Simultaneous exposure to noise and organic solvents such as styrene is an indispensable part of today’s industries. Numerous studies were done related to ototoxic effects of co-exposure to noise and styrene while some evidences showed the adverse effects of such exposure on other organs. In this study, we aimed to assess the subacute effects of combined exposure to noise and s...

In this study, stable lattices of terpolymer butyl acrylate, methyl methacrylate, and styrene were synthesized by a mini-emulsion polymerization technique using tert-butyl hydroperoxide TBHP/Fe2 /ethylenediaminetetraacetic acid/sodium formaldehyde sulfoxylate redox initiators at room temperature, and the kinetics of the reaction were studied. The reaction rate was obtained from periodic samplin...
