Fermi-Dirac and Bose-Einstein Functions of Negative Integer Order
(Theoretical and Mathematical Physics, 2009)
We find simple explicit closed-form formulas for the Fermi-Dirac function F(-n)(z) and Bose-Einstein function B(-n)(z) for arbitrary n is an element of N. The obtained formulas involve the higher tangent numbers defined ...
Effect of immobilization stress on gene expression of catecholamine biosynthetic enzymes in heart auricles of socially isolated rats
(Brazilian Journal of Medical and Biological Research, 2009)
Chronic stress is associated with the development of cardiovascular diseases. The sympathoneural system plays an important role in the regulation of cardiac function both in health and disease. In the present study, the ...
Transition metal complexes with thiosemicarbazide-based ligands. LIII. [4-(2-diphenylphosphino-alpha-ethoxybenzyl-kappa P)-S-methyl-1-(4-oxidopent-3-en-4-ylidene-kappa O)-thiosemicarbazido-kappa(2) N-1, N-4]nickel (II)
(Acta Crystallographica. Section C: Crystal Structure Communications, 2006)
The title compound, [Ni(C28H30N3O2PS)], crystallizes with two independent molecules in the asymmetric unit. The Ni-II atoms are in significantly deformed square-planar environments formed by an ONNP donor set from a ...
Influence of Organic Cations Sorption on the Point of Zero Charge of Natural Zeolite
(Hemijska industrija, 2009)
In this paper, the results of the surface modification of natural zeolite with different amounts (2, 5 and 10 mmol M(+)/100 g) of octadecyldimethylbenzyl ammonium ions (ODMBA) are presented. The obtained organozeohtes were ...
Subsolidus phase equilibria in the CeO2-x-SiO2-ZrO2 system: An experimental study
(International Journal of Materials Research, 2006)
The phase equilibria in the CeO2-xSiO2-ZrO2 system were studied in the subsolidus region in argon atmosphere, under isothermal heating and hot pressing, at 1400 degrees C, different ceria, silica, and zirconia mixtures. ...
Isothermal susceptibility in tetragonal phase of YBa2Cu3O6+2c
(Physica. C: Superconductivity and Its Applications, 2001)
Fluctuations in tetragonal phase of YBa2Cu3O6+2c compound are analyzed in terms of the two-dimensional asymmetric next-nearest-neighbor Ising (ASYNNNI) model. For several sets of interaction constants between oxygen atoms, ...
Inapplicability of Small-Polaron Model for the Explanation of Infrared Absorption Spectrum in Acetanilide
(Electromagnetic Biology and Medicine, 2009)
The applicability of small-polaron model for the interpretation of infrared absorption spectrum in acetanilide has been critically reexamined. It is shown that the energy difference between the normal and anomalous peak. ...
Detection of transforming growth factor-beta 1 in human plasma - A pilot study on breast cancer patients
(Jugoslovenska Medicinska Biohemija, 2001)
There has been much controversy concerning the detection of plasma TGF-beta (1) levels in breast cancer patients. The present study provides preliminary evidence on underestimated plasma TGF-beta (1) levels due to ex vivo ...
Estradiol affect Na-dependent Ca2+ efflux from synaptosomal mitochondria
(General Physiology and Biophysics, 2000)
The effects of gonadal steroid hormone, 17 beta-estradiol (E-2), in vitro on rat brain mitochondria Ca2+ movement were investigated. Intrasynaptosomal mitochondria Ca2+ uptake via an energy-driven Ca2+ uniporter have K-m ...
