pyrolysis of low density polyethylene (ldpe) by equilibrium fluid catalytic cracking (fcc) was studied in a stirred reactor under different process parameters. in this work, the effect of process parameters such as degradation temperature (420-510°c), catalyst/polymer ratio (0-60%), carrier gas type (h2, n2, ethylene, propylene, ar and he), residence time and agitator speed (0-300 rpm) on the c...

The physical characteristics of ultrasonically sprayed indium-doped zinc oxide (ZnO:In) thin films, with electrical resistivity as low as 3.42 × 10-3 Ω·cm and high optical transmittance, in the visible range, of 50%-70% is presented. Zinc acetylacetonate and indium chloride were used as the organometallic zinc precursor and the doping source, respectively, achieving ZnO:In thin films with growt...

OBJECTIVE We report on the effect of glutathione, an antioxidant compound on the airway response to the ultrasonically nebulised distilled water (UNDW, 'fog') challenge. METHODS 12 subjects with mild-to-moderate bronchial asthma underwent double-blind, cross-over pretreatment, administered 30 min earlier, in a randomised order with inhaled glutathione (G) (600 mg), sodium cromoglycate (SCG) (...

Tea waste was used to successfully synthesize magnetic nanoparticles (TWMNPs). In this investigation, Pb (II) eliminated by tea modified with magnetite (TWMNPs) investigated. To prepare the TWMNPs, FeCl3.6H2O dissolved in double distilled water (DDW) and 20 g of pulp added slowly stirred, after 30 min TWMNPs adsorbent were separated through an external field washed three times ethanol then drie...

Heterologous expression using baculovirus vectors has become a popular method for the production of catalytically active cytochrome P450s (CYPs). We have systematically optimized the multiplicity of infection (MOI) for a coinfection approach for the coexpression of CYP2A6 (viral vector designated v2A6) and NADPH-P450 oxidoreductase (OR; viral vector designated vOR) using Sf9 insect cells. A 300...

Abstract Funding Acknowledgements Type of funding sources: None. Background Intracardiac echocardiography (ICE) is becoming more common during the ablation atrial fibrillation (AF) and it may improve procedural effectiveness. However, there no evidence evaluating efficiency, effectiveness, safety outcomes ICE in context novel pulsed-field (PFA) AF. Purpose We aimed to evaluate impact on paramet...

We evaluated the mechanism of the anti-asthmatic effect of inhaled indomethacin (Indo) by using an animal model (guinea pigs) of airway inflammation. After being exposed to either ozone or room air at identical flow rates (5 l/min) for 2 h, guinea pigs were anesthetized, tracheostomized, and lung resistance (RL) was subsequently measured. Guinea pigs inhaled either saline or Indo (1.5 mg/ml) fo...

When the crisscross baffles and logarithmic spiral baffles are placed on the bottom of the stirred tank with elliptic bottom, using CFD software FLUENT simulates the velocity field of the stirred tank with elliptic bottom and bottom baffles. Compare the velocity field of stirred tank with bottom crisscross baffle to the velocity field of stirred tank without bottom baffle and analysis the flow ...
