Background: Multi-drug resistant (MDR) and extensively drug-resistant (XDR) Pseudomonas aeruginosa isolates are of clinical concern. Objectives: To determine the distribution antiseptic resistance genes associated level phenotypic against quaternary ammonium compounds biguanide compounds, we studied MDR XDR P. collected from different infections among patients a single hospital. Methods: were i...

In the present study, the application for the removal of phenylalanine by using two nano sorbents, namely, cetyltrimethylammonium bromide –Coated and BKC (benzal-conium chloride)-Coated Fe3O4 nanoparticles was investigated. Solid-phase extraction (SPE) and ultra violet–visible spectroscopy were used for studying the removal ability of each nano-sorbent in this study. Scanning Electron Microscop...

Experience in Queensland has shown that when crude BHC is refined to yield products containing higher proportions of the gamma isomer, the insecticidal persistence of the BHC in soil is decreased. This process also diminishes the specific toxicity of BHC to the soldier fly pest, Alfe~nzetopon.ia rubriceps (Macq.). I t also decreases the potential phytotoxicity, since less total BHC is required ...

The spectral value set sp ε A of a bounded linear operator A on l2 is the union of the spectra of all operators of the form A+ BKC, where ‖K‖ < ε and B,C are fixed bounded linear operators. It turns out that small changes of ε may cause drastic changes of the set sp ε A. We conjecture that this can never happen if B or C is compact and A is given by an infinite Toeplitz band matrix. In the pres...

Poly(ethylene terephthalate) (PET) powder was hydrolyzed at atmospheric pressure in 5-10 wt% aqueous NaOH at 95°C for 100 min using some phase transfer catalysts (PTC) with an intention to recover the starting monomers from the waste PET. The intent behind attempting new PTC was to carry out the reaction at milder conditions than those reported in the literature. One of the monomers, terephthal...

In this paper, we evaluate three extensions of the Erlang Multirate Loss Model by comparing them, based on the resultant call blocking probabilities for ABR services in ATM networks. In the first extension, the retry models, blocked calls can retry with reduced resource requirements and increased arbitrary mean residency requirements. In the second one, the threshold models, request sizes and r...
