The photodissocn. I2M + hn -> I2 + M was studied for M = C2H6 and M = (C2H5)2O with excitation above the dissocn. limit of I2B state. Vibrational population distributions of the I2(B) product mols. are reported. The results are compared to previous studies ...
To obtain addnl. insight into the release mechanism of the metals in electrothermal atomization at. absorption spectrometry, a quant. relation between the heat of vaporization and the size of the released particles is proposed from the Kelvin equation. The ...
In this work I discuss on the basis of the instantaneous recycling approximation the possibility of determining a relation between matter distribution (luminous and dark) in elliptical galaxies and the metallicity distribution. Two different contexts are c ...
A simple method is proposed for the estn. of the current bypass from exptl. current-potential (i-U) curves measured for a bipolar reactor and with a one-element cell of similar geometry. The model is valid only in the region where a linear i-U relation is ...
The author discusses: (1) cost of information, (2) quality of power supply and the value attributed to it depending on the use of energy, (3) opinion of operators of electric networks upon the rate of computer in their industry ...
We study the relation between the solutions of two minimization
problems with indebite quadratic forms. We show that a complete link between both solutions can be established by invoking a fundamental set of inertia conditions. While these inertia condit ...
A review with 75 refs. of calorimetric techniques used and results obtained in calorimetric expts. aimed at developing quant. relation between heat release and other important process parameters for potential use in monitoring and controlling tech. bioproc ...
A review with 7 refs. on polyelectrolytes and some of their tech. applications is given. Criteria for the classification of polyelectrolytes are shown e.g. origin, chem. compn., mol. architecture, and electrochem. [on SciFinder (R)] ...
Arterial vasomotion and its relation to intraluminal pressure were investigated in vitro in isolated rat arteries. Femoral arteries (mean diameter = 768.2 +/- 25 microns, n = 5) and mesenteric arteries (mean diameter = 393.4 +/- 32 microns, n = 5) were use ...
We review the well-known relation between Lucas sequences and exponentiation. This leads to the observation that certain public-key cryptosystems that are based on the use of Lucas sequences have some elementary properties their re-inventors were apparentl ...
