Let us consider the following problem. Imagine a homogeneous nonlinear medium in which only one type of wave with dispersion law co(k) may propagate. Let the nonlinearity of the medium be quadratic while the equation co(k~ + k~) = co(k0 + co(k2) (1) defines a nonzero manifold F whose codimension in kl, k2 space is unity. Equation (1) means that dispersion law co(k) allows decay processes. The n...

today the image of a permanent skeletal space of cities affected by some forces or mechanisms is put in time with social-economic development and while imposes a new face and perspective to physical anatomy of cities, and prepares field to changes in content and social- economic structures of cities too. simultaneously with quitting villages in order to settle in cities by villagers, the phen...

Because of the lack of readily available information about the influence of temperature on microorganism reactivation processes subsequent to inactivation with UV radiation, a series of batch reactivation studies were performed at 5, 10, 15, 20, 25, and 30 degrees C. A special effort was made to model the reactivation process to enable the effect of the temperature variable to be quantified. Be...

There have been many studies of thermal Green functions in gauge field theories [1–7], which show that their behavior at finite temperature is rather different from the one at zero temperature. In particular, it was recently pointed out by Weldon [8] that in QED, the logarithmic branch cut singularities cancel to one loop-order, in the thermal self-energy of the electron. The purpose of this no...

A partial-wave analysis of the decay J/ψ → K+ K−π0 made using (223.7 ± 1.4) 106 events collected with BESIII detector in 2009 [1] will be presented and discussed. We report most precise measurements K*(892)± K2*(1430)± mass width. The reveals contributions from K2*(1980)± K4*(2045)± for first time decays. Two resonance signals decaying to K+K− are also observed their possible interpretations Re...

y-Radiolysis of N20-saturated water or photolysis of aqueous H2O2 provided a source of OH radicals. These radicals react with ethanol by preferentially abstracting an H atom at C-l. In the presence of oxygen these radicals are converted into the corresponding peroxyl radicals. The a-hydroxyethylperoxyl radicals decay by first order kinetics (k = ki + k2 [OH -]) acetaldehyde and H02/H+ + 01 bein...

We estimate the asymptotic behavior for the Stokes solutions, with external forces first. We ∧ found that if there ∧ are external forces, then the energy decays ∧ slowly even if the forces ∧ decay quickly. Then, we also obtain the asymptotic ∧ behavior in the temporal-spatial direction for weak solutions of the Navier–Stokes equations. We also provide a simple example of external forces which s...

background: klebseilla pneumoniae causes urinary tract infections, nosocomial pneumonia and intra-abdominal infections. capsular antigens are considered to be the ultimate virulence determinants. among 77 capsular serotypes of k. pneumoniae, serotypes k1 and k2 are the most virulent ones in humans. objectives: we designed a pcr method for detection of capsular serotypes k1 and k2 of k. pneumoni...

We present a measurement of the decay amplitudes in B-->J/psiK*(892) channels using 20.7 fb(-1) of data collected at the Upsilon(4S) resonance with the BABAR detector at PEP-II. We measure a P-wave fraction R(perpendicular) = (16.0 +/- 3.2 +/- 1.4)% and a longitudinal polarization fraction (59.7 +/- 2.8 +/- 2.4)%. The measurement of a relative phase that is neither 0 nor pi, phi = 2.50 +/- 0.20...
