Charge Distribution in Chiral Pion Bremsstrahlung

Charge distribution of pions in multiple production processes drew much attention recently. The growth of interest in this subject is due to expectations to detect the disoriented chiral condensate (DCC) formation in high energy collisions . The simplest picture of the process is given by ”Baked Alaska scenario” , where coherent pulses of semiclassical pion field are emitted leading to anomalou...

Glomerular size and charge selectivity in the rat as revealed by FITC-ficoll and albumin.

The fractional clearances (theta) for FITC-Ficoll and albumin were estimated in isolated perfused rat kidneys in which the tubular activity was inhibited by low temperature (8 degrees C) and/or 10 mM NH(4)Cl. The Ficoll data were analyzed according to a two-pore model giving small and large pore radii of 46 A and 80-87 A, respectively. The estimated negative charge density was 35-45 meq/l at 8 ...

Tris(indolyl)methene molecule as an anion receptor and colorimetric chemosensor: tunable selectivity and sensitivity for anions.

Simple tris(indolyl)methene receptors 1-3 containing conjugated bisindole skeletons have been designed and synthesized. The anion binding and sensing properties have been studied using UV-vis spectroscopy and (1)H NMR titration technique. Compared with 3,3'-bis-indolyl phenylmethene (4), tris(indolyl)methene receptors could highly selectively detect F(-) based on two stages of proton transfer, ...

Tetrathiafulvalene diindolylquinoxaline: a dual signaling anion receptor with phosphate selectivity.

Incorporation of tetrathiafulvalene into the backbone of a known neutral phosphate receptor, diindolylquinoxaline, yields a dual optical-electrochemical chemosensor for dihydrogen phosphate that functions in dichloromethane. This system shows selectivity for dihydrogen phosphate over other small anions and can be used to detect the presence of this analyte via fluorescence quenching or cyclic v...

Crystal size and shape distribution of plagioclase in the basaltic andesites, North of Gavkhouni

Plagioclase is the most abundant mineral in basaltic andesites in the north Gavkhouni. Olivine and pyroxene are the other rock forming mineral there. In their 3-dimensional shapes, they are unequal and varies between bladed to prolate. Plagioclase sometimes exhibit dusty texture, oscillatory zoning and sinusoid growth. Based on crystal size distribution data, the rate of crystal nucleation of p...
