A simple, precise, rapid and low-cost potentiometric method for pethidine determination in pharmaceuticals and urine is proposed a chemically modified carbon paste electrode (cmcpe) for pethidine hydrochloride (pdcl) based on pethidine-phosphotungstate (pd-pt) as ion-pair complex was prepared and fully character-ized in terms of composition, usable ph range, response time and temperature. Identification of a mg-protoporphyrin ix monomethyl ester cyclase homologue, eazip, differentially expressed in variegated epipremnum aureum `golden pothos' is achieved through a unique method of comparative study using tissue regenerated plants academic article. A molecular dynamics model for tributyl phosphate (tbp) and diamyl amyl phosphonate (daap) is presented using the generalized amber force field (gaff) and the am1-bcc method for calculated atomic charges with a modification to the phosphorus-containing dihedral parameters.

Study of the genetic discrimination between imported and autochthonous cases of malaria in south korea academic article study of the molecular recognition of aptamers selected through ovarian cancer cell-selex academic article. Trl~ comparative extraction of u(vi), presumably as uo2(no3)2s2, where s represents the extractant molecule, from an aqueous nitrate phase by neutral phosphate and phosphonate esters has been studied by a number of investigators(l, 2, 3,, 4) who agree that a given phosphonate is superior to the analogous phosphate. A potentiometric precipitation titration was also applied as a comparative method in this method 100 ml of sample solution of 01 m in(iii) was titrated with 5 x 10 − 2 mnaoh.
A comparative study of the mechanical properties of multilayer mos2 and graphene/mos2 heterostructure: effects of temperature, number of layers and stacking order, n ghobadi, current applied physics, 17, 1483-1493 (2017. A study conducted in finland determined the occupational exposure of workers to brominated flame retardants and chlorinated flame retardants (tbbpa, pbdes, dbdpe, hbcd, hexabromobenzene and dechlorane plus. A comparative study on extrac- tion of fe(iii) from chloride leach liquor using tbp, cyanex 921 and cyanex 923 hy- drometallurgy 104, 298-303.
Thermodynamics and kinetics of thermal decomposition of dibutylalkyl and dipentylalkyl phosphonate-nitric acid systems chromatography using tbp coated xad-4 resin. Indian journal of chemical technology vol 15, may 2008, pp 209-215 effect of substrate concentration on the transient dynamics of specific cell growth during bioconversion of cr +6 to cr +3 using polyculture consortia. Present study showed that the homologues of neat dibutylalkyl phosphonates and dipentylalkyl phosphonates are thermally more stable than their acid-solvates decomposition of these acid-solvated phosphonates were exothermic in nature and followed first order kinetics.
Bifunctional phosphonates have potential applicability to separating americium, curium, and rare earths from all of the other fission products in fuel reprocessing wastes without prior destruction of the hn03. Study triphenyl phosphate flame retardant electrolytetriphenyl phosphate | flame tpp triphenyl phosphate flame retardant electrolyte solution is a function of the electrolyte, the electrolyte such flame retardant functions are often added in a conventional electrolyte additive obtained. Tracted by tributyl phosphate (tbp) as well as taken up by tbp/xad-48 and ce(iii) extracted by dihexyl n,n- diethylcarbamoylmeth~phosphonate (cmp) and cmp/xad-49. Results in order to study the response of halobacterium sp nrc-1 to two common stressors, salinity and temperature, we used whole genome dna microarrays to assay for changes in gene expression under differential growth conditions.
Interspecies differences 25 the dose descriptor is obtained from an inhalation study it is therefore not necessary to apply an allometric scaling factor to take account of differences in basal metabolic rates between animals and humans. In our study, substitutions were observed in the 3' to 5' exonuclease and 5' to 3' polymerase domains of the mpv dna polymerase (table (table1, 1, figure figure2, 2, figure 3a, b) consistent with previous studies in vacv [10,12,20.
There is experimental data for the enthalpy of mixing for tbp across a range of volume fractions in three of the solvents considered in this study: n-dodecane, n-hexane and benzene. A 10 gal of 10 mg/ml (or 10 g/l) solids concentration coating solution of 50% by weight of the fluoro-poss polymer and 50% by weight of the tecnoflon br9151 fluoroelastomer was prepared for this study using the asahiklin ak-225 solvent with constant stirring at 25°c overnight prior to the conducting trials. Thermal stability of neat and nitric acid-solvated dibutylalkyl and dipentylalkyl phosphonates was studied under closed air ambience using an adiabatic calorimeter enthalpies and kinetic parameters for the decomposition reaction were derived wherever possible and are reported for the first time.
