Saffron is grown in arid and semi-arid regions in Iran in late autumn, winter and late spring with rainy season. It should be irrigated by supplemental basin irrigation. Since rainfall is usually delayed in autumn, therefore, a pre-flowering irrigation of about 100 mm is needed. In areas with a seasonal rainfall of 600 mm a post- flowering irrigation of about 50 mm is adequate for economical yi...

Mallat et al. [1] proved that modulus maxima of the wavelet coefficients give the complete representation of the signal and they proposed an iterative algorithm to remove noise. In the singularity analysis context, Xu et al. [3] developed a noise filtration method based on the spatial correlation between the wavelet coefficients over adjacent scales. An improved version is proposed by Pan et al...

We evaluate the virial coefficients Bk for k ≤ 10 for hard spheres in dimensions D = 2, · · · , 8. Virial coefficients with k even are found to be negative when D ≥ 5. This provides strong evidence that the leading singularity for the virial series lies away from the positive real axis when D ≥ 5. Further analysis provides evidence that negative virial coefficients will be seen for some k > 10 ...

Polyacrylonitril (PAN)-supported chitosan (CS) nanocomposite membranes were prepared by cross-linking the CS with 3-aminopropyl-triethoxysilane (APTEOS) via sol-gel method. Pervaporative performances of the CS-SiO2/PAN membrane for dehydration of aqueous alcohol solutions were investigated. From SEM cross-sectional images of the membrane, the spongy pores and the finger-like pores we...

water is the most limiting factor in irrigated agriculture, mainly in mediterranean environments, as in the case of southwest spain. in this area, almond is one of the most valuable crops due to its high drought tolerance. this work examines the crop coefficients (kc) based on four drainage lysimeters installed in an experimental young almond orchard. complementary, two deficit-irrigation treat...

We prove the divisibility conjecture on sums of even powers q-binomial coefficients, which was recently proposed by Guo, Schlosser and Zudilin. Our proof relies two q-harmonic series congruences due to Shi Pan.

This paper gives a qualitative description how Young tableaux can be used to perform a Clebsch-Gordan decomposition of tensor products in SU(3) and how this can be generalized to SU(N).

This essay describes the development of groups used for the specification of symmetries from ordinary and magnetic point groups to Fedorov and magnetic space groups, as well as other varieties of groups useful in the study of symmetric objects. In particular, we consider the problem of some incorrectness in Vol. A of the International Tables for Crystallography. Some results of tensor calculus ...
