Based on the two types of bounded domains in C^n, firstly using different method and technique we derive the corresponding integral representation formulas of differentiable functions for complex n-m(0 ≤ m < n) dimensional analytic varieties in the two types of the bounded domains. Secondly we obtain the unified integral representation formulas of differentiable functions for complex n-m(0 ≤ m < n) dimensional analytic varieties in the general bounded domains. When functions are holomorphic, the integral formulas in this paper include formulas of Stout^([1]), Hatziafratis^([2]) and the author^([3]),and are the extension of all the integral representations for holomorphic functions in the existing papers to analytic varieties. In particular, when m = 0, firstly we gave the integral representation formulas of differentiable functions for the two types of bounded domains in C^n. Therefore they can make the concretion of Leray-Stokes formula. Secondly we obtain the unified integral representation formulas of differentiable functions for general bounded domains in C^n. So they can make the Leray-Stokes formula generalizations.展开更多

The main goal of the article is to describe two modern scientific discoveries—New Geometric Theory of Phyl-lotaxis (Bodnar’s Geometry) and Hilbert’s Fourth Problem based on the Hyperbolic Fibonacci and Lucas Functions and “Golden” Fibonacci -Goniometry ( is a given positive real number). Although these discoveries refer to different areas of science (mathematics and theoretical botany), however they are based on one and the same scien-tific ideas—The “golden mean,” which had been introduced by Euclid in his Elements, and its generalization—The “metallic means,” which have been studied recently by Argentinian mathematician Vera Spinadel. The article is a confirmation of interdisciplinary character of the “Mathematics of Harmony”, which originates from Euclid’s Elements.展开更多

The two prepared formulas reduced the changes in body weight and liver weight caused by CCl4 in rats. The toxicity of CCl4 is related to loss in body weight and increase in liver weight in rats. The weight ratios of liver to body weight (LW/BW) significantly increased in rats treated with CCl4 followed by other groups. Formulas 1 and 2 could play an important role in improvement of hematological indices in liver cirrhosis rats. Feeding treated rats on special formulas showed improvement in liver function compared to rats fed on basal diet, reflected by significant reduction of the activity of transaminases (ALT and AST), alkaline phosphatase (ALP) and total bilirubin. There was a significant increase in total protein, albumin and globulin in serum. Significant increase in liver weight in rats treated with CCl4. There are no histopathological changes in all groups under study except for group 4 (CCl4 treated rats fed on basal diet) which orally administrated with CCl4 and had congestion of central vein and hepatic sinusoids.展开更多
