Antioxidants are vital substances which possess the ability to protect the body from damage caused by free radical-induced oxidative stress. A variety of free radical scavenging antioxidants exist within the body which many of them are derived from dietary sources like fruits, vegetables and teas. This article describes a test method for screening the antioxidant activity of 60 Iranian plant...

Antioxidants are vital substances which possess the ability to protect the body from damage caused by free radical induced oxidative stress. A variety of free radical scavenging antioxidants exist within the body which many of them are derived from dietary sources like fruits, vegetables and teas. In this study the antioxidant activity and radical scavenging activity of methanolic extracts of s...

In this paper, an enhancement design of communication system using optical radio frequency (RF) waves in free space optical communication (FSO) system is presented. To our knowledge, it is the first time that the effect of Gamma-Gamma turbulent channel model on the performance of the proposed system is analyzed and simulated. To obtain an optical communication system with good performance and h...

Aqueous solutions of mono, di, and triprotic acids were prepared with different molar percentages (say 10%, 20% and 30%). ammonium dihydrogen phosphate is gradually introduced in the aqueous solutions at different concentrations varied from 0.1M to 0.6M at 303K. Densities, viscosities, and velocity of sound of aqueous solutions are measured and they are used to evaluate the other parameters lik...

Let n,k and r ≥ 8 be positive integers. Suppose that a family F ⊂ ([n] k ) satisfies F1∩·· ·∩Fr 6= / 0 for all F1, . . . ,Fr ∈F and ⋂ F∈F F = / 0. We prove that there exist εr > 0 and nr such that |F | ≤ (r +1) ( n− r−1 k− r ) + ( n− r−1 k− r−1 ) holds for all n and k, satisfying n > nr and | k n − 2 |< εr.

The concepts of free modules, projective modules, injective modules and the likeform an important area in module theory. The notion of free fuzzy modules was introducedby Muganda as an extension of free modules in the fuzzy context. Zahedi and Ameriintroduced the concept of projective and injective L-modules. In this paper we give analternate definition for projective L-modules. We prove that e...
