We report the cw laser emission of (F+2)* centre in NaF Mg2+ under pumping by a laser diode array. Our laser is tunable between 1.03 and 1.12 μm. Its output power is 7.8 mW for 400 mW pump power.A method for the precise coulometric titration of platinum(IV) with electrogenerated chlorocuprous ion in KClCuEDTA buffer medium is described. From 2.7 to 18.7 mg of platinum in pure platinum and platinum alloy are determined with standard deviations of less than or equal to 0.034% using potentiometric end point detection. The method has good accuracy and precision, selectivity and rapidity.
The main object of the present paper is to investigate a number of inclusion relationships and some other useful properties of several interesting subclasses of analytic and pp-valent functions, which are defined here by means of a certain linear operator. Relevant connections of the results presented here with those obtained in earlier works are also pointed out.A quantitatively useful approximation method is developed for generating complete multi-fragment events in a statistical model for nuclear disassembly. The method consists in factorizing the exclusive microcanonical probability distribution into successively dependent one-fragment inclusive distributions, each of which is approximated by Pull Hollister Femme Rose its respective truncated grand canonical equivalent.
In this paper, we derive extremality and comparison results for first-order explicit and implicit functional differential equations equipped with functional initial conditions. Differential equations and initial conditions may involve discontinuities.The paper is concerned with http://www.pronomania.fr the schedule optimization problem in the railway control systems. The schedule optimization problem has been formulated as a problem of finding the global extreme of the fitness function. Authors propose 2 different methods for the problem solving using mathematical optimization technologies, namely stochastic optimization algorithm, and the genetic algorithm respectively.
The continuum contribution is calculated of the two-photon exchange amplitudes in lepton-hadron (spin-zero) scattering at low-momentum transfer. The results are of general validity, either for muons or electrons. The e±−4He asymmetry is also estimated and turns out to be near 10−2, somehow bigger than for μ±.Antimony can be quantitatively extracted from 1M sulphuric acid containing 0.25M potassium iodide with 0.02M 18-crown-6 in methylene chloride, and determined spectrophotometrically at 430 nm. Bismuth, tin, antimony and arsenic can be separated by sequential extraction with Hollister Sweat Shorts Guys 18-crown-6 from aqueous phases with appropriately adjusted sulphuric acid and potassium iodide concentrations.
