We present Monte Carlo simulations on Eley-Rideal abstraction reactions of atomic hydrogen chemisorbed on graphite. The results are obtained via a hybrid approach where energy barriers derived from density functional theory calculations are used as input to Monte Carlo simulations. By comparing with experimental data, we discriminate between contributions from different Eley-Rideal mechanisms. ...

In our previous studies, we have shown that the diffusing probe geometry can be used in conjunction with a two-layer diffusion model to accurately recover the absorption and scattering properties of skin in vivo. By modifying the original design to the diffusing probe with planar source (DPPS) geometry, we have also demonstrated that the efficiency of the accompanying multilayer diffusion model...

The search for better antimicrobial agent due to rapid appearance of multidrug resistant microorganism and antimicrobial properties of semicarbazones and 2,5-disubstituted 1,3,4-oxadiazoles prompted us to undertake the synthesis of a few novel N-[5-(4-substitutedphenyl)-1,3,4-oxadiazol-2-yl]-N-(4substitutedbenzaldehyde)-semicarbazone and N-[5-(4-substitutedphenyl)-1,3,4-oxadiazol-2-yl]-N-[1-(4s...

In the practical problems such as nuclear waste pollution and seawater intrusion etc., many are reduced to solving convection-diffusion equation, so research of equation is great value. this work, a spectral method presented for one two dimensional with source term. The finite difference also used solve convection diffusion equation. numerical experiments show that more efficient than other met...

The antibacterial activities of five antibiotics, three brands of Ofloxacins (Obenasin, Floxavid and Drovid) and two brands of Ciprofloxacins (Uroxin and Siprosan), and five commonly used disinfectants (Lysol, Dettol, Purit, Roberts and Wex-cide) against Staphylococcus aureus, Escherichia coli, Proteus spp., Pseudomonas aeruginosa, Streptococcus spp. and Bacillus spp. were investigated. The gro...

Fifty strains of Staphylococcus intermedius were isolated from different pathological specimens originating from dogs during a six-month period. Antimicrobial susceptibility patterns against three fluoroquinolones were obtained on 50 Staphylococcus intermedius strains. In vitro antimicrobial susceptibility testing was performed employing the disk diffusion method (Kirby-Bauer). The sensitivity ...

The performance of the MicroScan WalkAway PC30 panel for detection of oxacillin resistance was evaluated by use of a collection of 420 staphylococcus isolates. The addition of a cefoxitin test (4 mg/liter) to the oxacillin MIC determination increased its raw performance for Staphylococcus aureus; additional data were required for coagulase-negative staphylococci.
