objective(s) to determine the potential toxic effects of manual soldering flux cored solder wire on lung of the rat as an experimental model. materials and methods a total number of 48 adult male rats were divided into experimental (n= 30) and control (n= 18) groups. based on exposure time to solder fume, each group was further subdivided into 2, 4 and 6 week subgroups. rats of experimental gro...

Seed oil content is a key agronomical trait, while the control of carbon allocation into different seed storage compounds is still poorly understood and hard to manipulate. Using bna572, a large-scale model of cellular metabolism in developing embryos of rapeseed (Brassica napus) oilseeds, we present an in silico approach for the analysis of carbon allocation into seed storage products. Optimal...

NADPH regeneration capacity is attracting growing research attention due to its important role in resisting oxidative stress. Besides, NADPH availability has been regarded as a limiting factor in production of industrially valuable compounds. The central carbon metabolism carries the carbon skeleton flux supporting the operation of NADPH-regenerating enzyme and offers flexibility in coping with...

Austenitic stainless steel SS304 grade was welded with active Tungsten Inert Gas (TIG) welding process by applying a flux paste made of SiO2 powder and acetone. SiO2 flux application improves the weld bead depth with a simultaneous reduction in weld bead width. The improvement in penetration results from arc constriction and reversal of Marangoni convection. Experimental studies revealed that t...

Single crystals of the new uranium lanthanide oxyselenide compounds UYb2O2Se3 and U2Ln2O4Se3 (Ln1⁄4Pr, Sm, Gd) have been synthesized from an Sb2Se3 flux. The structures have been determined from single-crystal X-ray diffraction data. UYb2O2Se3 is isostructural to UYb2O2S3. The structure comprises layers of edge-sharing YbSe6 octahedra and double layers of disordered (U/Ln)O4Se4 square antiprism...

Results reported here highlight the potential and several challenges in the development of a novel osmotic membrane bioreactor (OMBR) process for the treatment of municipal wastewater. Following the initial gradual decline, a stable permeate flux value was obtained after approximately four days of continuous operation. There was evidence of continuous deterioration of biological activity of the...

Hydrogen forms more compounds than any other element in the Periodic Table, yet methods for accurately, precisely and rapidly determining its position in a crystal structure are not readily available. The latest generation of high-flux neutron powder diffractometers, operating under optimised collection geometries, allow hydrogen positions to be extracted from the diffraction patterns of polycr...
