in this study, substitution at codon ser315 of katg gene, a reliable marker for isoniazid (inh) resistance was analyzed and compared by three molecular methods such as dna sequencing, polymerase chain reaction restriction fragment length polymorphism (pcr-rflp) and pcr-single strand conformation polymorphism (pcr-sscp) in 105 phenotypically resistant isolates obtained from various parts of indi...

background: xanthomonas citri subsp. citri (xcc), the causative agent of bacterial citrus canker, has affected citriculture worldwide. varieties of means have been used to minimize its devastating effects, but no attention has been given to bacteriocins.objectives: here and for the first time, we report the isolation and characterization of two novel bacteriocins.materials and methods: secretom...

a bench scale aerobic sequencing batch reactor (sbr) was evaluated in terms of its potential to treat synthetic dairy wastewater. the 2-l plexiglass bioreactor was supplied with oxygen via a fine bubble air diffuser, fed with synthetic dairy wastewater under various operational conditions. to analyze the process, three significant independent variables — influent chemical oxygen demand (cod), m...

the statistical analysis of spatial data is usually done under gaussian assumption for the underlying random field model. when this assumption is not satisfied, block bootstrap methods can be used to analyze spatial data. one of the crucial problems in this setting is specifying the block sizes. in this paper, we present asymptotic optimal block size for separate block bootstrap to estimate the...

normal 0 false false false en-us x-none ar-sa background: regional anesthesia is widely used to perform different surgical procedures including those performed on the extremities . in this study, the anesthetic effects of adding intrathecal neostigmine or magnesium sulphate to bupivacaine in patients under lower extremities surgeries were assessed. materials and methods: in this double-blind ra...

Abstract. We describe the development of a block-structured, equal-CPU-load (central processing unit), multi-grid-nesting interface for Boussinesq wave model FUNWAVE-TVD (Fully Nonlinear Wave Model with Total Variation Diminishing Solver). The new framework does not interfere core solver, and thus program, FUNWAVE-TVD, is still standalone used single grid. nesting manages time sequencing two-wa...
