We develop a simple iterative scheme to include vertical turbulent mixing and diffusion in PRODIMO thermo-chemical models for protoplanetary discs. The are carefully checked convergence towards the time-independent solution of reaction-diffusion equations, as, example, used exoplanet atmosphere models. A series five TTauri disc is presented where we vary parameter α mix from zero 10 −2 take int...

A series of curcumin derivatives containing heterocyclic moiety have been synthesized and evaluated for their antibacterial activities. The chemical structures of the synthesized compounds were verified on the basis of spectral data and elemental analyses. Investigation of antimicrobial activity of the derivatives demonstrated the ability to inhibit Gram-positive microorganisms with zone of inh...

Background and Objective: Nowadays, incidence of antibiotic-resistance among pathogenic bacteria has increased due to indiscriminate use of antimicrobial drugs for treatment of diseases, especially urinary tract infections. Medicinal plants are also of great importance as antibacterial agents. Therefore, the aim of this study was to determine the antibacterial effect of ethanolic extract of n...

OBJECTIVE To determine the prevalence of extended spectrum b-lactamase at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia and to compare the ability of the disc diffusion, double disc potentiation methods and the extended-spectrum b-lactamase E test to detect exended-spectrum b-lactamase among enterobacteriaceae. METHODS This study was undertaken during the time period period...

Methanolic extract of Trianthema decandra was investigated for its antibacterial activity against staphylococcus aureus (NCIM 2079), Escherichia coli (NCIM 2065), Bacillus subtilis (NCIM 2063), Pseudomonas aeruginosa (NICIM 2036) and Proteus vulgaris (NICIM 2027) at 100 μg/disc using disc diffusion method. The extract showed significant antibacterial activity and were comparable to Chlorampheni...

OBJECTIVE To assess the frequency of phenotypic expression of inducible resistance of clindamycin due to expression of erm genes, in clinical isolates of Staphylococcus aureus (S. aureus), by double disk diffusion test (D-test). METHOD This was a cross sectional study conducted in the clinical laboratory of Aga Khan University Hospital, Karachi. A total of 2432, non duplicate clinical isolate...
