High speed synchrotron X-ray imaging and ultrafast tomography were used to study in situ real time the fragmentation growth dynamics of dendritic microstructures an Al-15%Cu alloy solidification under ultrasound. An ultrasound 30 kHz with vibration amplitude 29 µm was applied into melt produced a strong swirling acoustic flow ~0.3 m/s. Efficient dendrite occurred due dominant mechanism is therm...

We examine the effect of the Amnesty Plus policy on firms’ incentives to engage in cartel activities. Amnesty Plus is a proactive antitrust enforcement strategy aimed at attracting amnesty applications by encouraging firms already convicted in one market to report collusive agreements in other markets. It has been heavily advertised that Amnesty Plus weakens cartel stability. We show to the con...

This cytogenetic and pharmacological study attempts to clarify genotoxicity-enhancement-effect of dl-α-tocopherol (one form of vitamin E) in combination with the herbicide 1,1'-dimetyl-4,4'-bipyridium dichloride (paraquat, PQ) on cultured anuran leukocytes using the superoxide dismutase-mimic Mn(III)tetrakis(1-methyl-4-pyridyl)porphyrin (Mn(III)TMpyP), the hydrogen peroxide-scavenger catalase a...

in order to investigate the effect of irrigation and nitrogen fertilizer on yield and yield components of (anethum graveolens l.), a field experiment was performed in agricultural research farm of the university of tabriz, iran, during growing season of 2009-2010. the experiment was carried out as split plot based on randomized complete block design with three replications. irrigation treatment...

In most double-stranded RNA (dsRNA) viruses, RNA transcription occurs inside a polymerase (Pol) complex particle, which contains an RNA-dependent RNA Pol subunit as a minor component. Only plus- but not minus-sense copies of genomic segments are produced during this reaction. In the case of phi6, a dsRNA bacteriophage from the Cystoviridae family, isolated Pol synthesizes predominantly plus str...
