A synthesized bis(dibenzoylmethanato)Co(II) complex (Co(DBM)(2)), has been used as a ionophore for the preparation of a new perchlorate ion-selective electrode. The electrode exhibits a Nernstian response over the perchlorate concentration range of 8.0x10(-7)-1.0x10(-1)M with a slope of 60.3+/-0.5 mV per decade of concentration. The limit of detection as determined from the intersection of the ...

Gel polymer electrolytes (GPEs) are developed using poly(1-vinylpyrrolidone-co-vinyl acetate) [P(VP-co-VAc)] as the host polymer, lithium bis(trifluoromethane) sulfonimide [LiTFSI] as the lithium salt and ionic liquid, and 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide [EMImTFSI] by using solution casting technique. The effect of ionic liquid on ionic conductivity is studied and...

We present a simple yet highly sensitive single-beam experimental technique for the determination of both the sign and magnitude of n(2). The sample is moved along the z direction of a focused Gaussian beam while the repetitively pulsed laser energy is held fixed. The resultant plot of transmittance through an aperture in the far field yields a dispersion-shaped curve from which n(2) is easily ...

In an earlier publication [1] it has been claimed that oxidative coupling of methane to higher hydrocarbons had been obtained with close to 100% selectivity at 600~ and atmospheric pressure in the presence of steam over a CaNiK oxide catalyst. These results have been confirmed in longer runs. Artifacts, such as carbonate formation on the catalyst, have been excluded. The reaction is slightly ex...

A common approach to interactive narrative involves imbuing the computer with all of the potential story preauthored story experiences (e.g. as beats, plot points, planning operators, etc.). This has resulted in an accepted paradigm where stories are not created by or with the user; rather, the user is given piecemeal access to the story from the gatekeeper of story knowledge: the computer (e.g...

It is debated whether species-level differences in ecological strategy, which play a key role in much of coexistence theory, are important in structuring highly diverse communities. We examined the co-occurrence patterns of over 1100 tree species in a 25-hectare Amazonian forest plot in relation to field-measured functional traits. Using a null model approach, we show that co-occurring trees ar...

Amino acid (aa) sequence segments similar to those of these three cell-division gene products were searched for from PIR Database, by Lipman-Pearson method using Genentyx Software (Software Development Co., Tokyo). Thus found possibly homologous sequence segments were re-analyzed by dot-matrix method (Harr-Plot), and the corresponding base-sequence alignments (m-base-match in n-base-alignment) ...

The aim of this study was to determine the effects pasture (cocksfoot cv. porto (CFP) and lucerne) supplementation grazing lambs with pellets or without plant oil infusion on performance carcass characteristics. Forty-eight White Suffolk x Corriedale first-cross weaners were randomly assigned one four treatments in a split-plot experimental design: (1) CFP lucerne pastures only (control); suppl...

The undamped naturalfrequency CO, and the damping ratio [ can be determined from a plot of the jiee motion of the system. If the damping is light, ( < 0.2, the lqqarithmic decrement can be used to determine the coeficients. Systems with moderate damping are those in the range 0.2 < ( -C 1.2. A methodfor determining vibration parameters for systems with moderate damping is presented here. The me...
