re-vegetation of bare soil is believed to increase, or at least maintain the organic matter levels of soil. the aim of this study was to investigate the soil characteristics changes, nutrient pool sizes and their availability under mid canopy, and canopy gap positions of saltbush in an area re-vegetated with atriplex lentiformis. some of the physical and chemical soil characteristics (the parti...

here, a finsler manifold $(m,f)$ is considered with corresponding curvature tensor, regarded as $2$-forms on the bundle of non-zero tangent vectors. certain subspaces of the tangent spaces of $m$ determined by the curvature are introduced and called $k$-nullity foliations of the curvature operator. it is shown that if the dimension of foliation is constant, then the distribution is involutive a...

salinity, as an abiotic stress, causes significant losses in horticultural production. future of grape production, as one of the most important economical horticultural fruits, depends on breeding programs and using salt tolerant rootstocks. the aim of this study was to investigate the salinity tolerance and the distribution of ions associated with salinity in six genotypes and varieties of gra...

We compute the limiting distribution, as n → ∞, of the number of cycles of length between γn and δn in a permutation of [n] chosen uniformly at random, for constants γ, δ such that 1/(k + 1) ≤ γ < δ ≤ 1/k for some integer k. This distribution is supported on {0, 1, . . . , k} and has 0th, 1st, ..., kth moments equal to those of a Poisson distribution with parameter log δ γ . For more general ch...

The distribution of the number of trials until the first occurrence of consecutive k successes in Bernoulli trials with success probability p is called a geometric distribution of order k. This definition is due to Philippou, Georghiou and Philippou (1983). Though the distribution seems to have been interested since De Moivre (1667-1754)’s works (Todhunter (1865), Feller (1968), Johnson, Kotz a...

Abstract: This paper introduces three generalized geometric distributions: the binomial, negative binomial and Poisson distribution of the same order k. The generating functions and probability distributions of them are investigated, and then the corresponding modes of the distributions are discussed. By the Fibonacci sequence, the modes of the negative binomial distribution of order k are deri...
