Allene (H2C═C═CH2; a-C3H4) and propyne (CH3C≡CH; p-C3H4) are important species in various chemical environments. In combustion processes, the reactions of hydroxyl radicals with a-C3H4 and p-C3H4 are critical in the overall fuel oxidation system. In this work, rate coefficients of OH radicals with allene (OH + H2C═C═CH2 → products) and propyne (OH + CH3C≡CH → products) were measured behind refl...

The broomrape, Orobanche crenata Forsk (Orobanchaceae) is a serious annual parasitic weed that causes considerable losses in many major crops including faba bean (Vicia L.). In Egypt: due to O. crenata parasitism may reach 40 100%. Despite using several methods control crenata, success has not been achieved. impact of different tactics on crenata is well understood....

   Background & Objective:  Peroxisome biogenesis disorders (PBDs) are a group of diseases with peroxisomal dysfunction. Wide range of symptoms are associated with the disease which are due to mutations in the PEX genes. The PEX1 mutation occurs in Zellweger syndrome (ZS), a severe autosomal recessive condition with hypotonia, intellectual disability, and hepatic enlargement. The present study ...

Ultrafine elongated grain (UFEG) structure with a strong <110>//rolling direction fiber texture was created for 0.4%C-2%Si-1%Cr-1%Mo steel (mass%) through deformation of tempered martensite using multi-pass caliber rolling at 773 K reduction 78% (i.e. warm tempforming). Annealing the tempformed 843 enhanced delamination toughening lower temperatures without significant loss tensile strength 1.8...
