A realistic energy-oriented model is necessary to formally characterize the energy consumption and the consequent carbon footprint of actual and future high-capacity WDM networks. The energy model describes the energy consumption of the various network elements (NE) and predicts their energy consumption behavior under different traffic loads and for the diverse traffic types, including all opti...

the aim of the present study was the conducting of comparative analysis of allele pool of ukrainian population of thoroughbred horses and the populations from england, usa, russia and south korea using microsatellite loci of dna on the basis of our own researches and literary sources. comparative analysis of allele pool of thoroughbred populations from different countries was conducted using 6 ...

bilingual dictionary use in l2 writing test performance has recently been the subject of debate. opinions differ according to how the trait is understood and whether the system favors the process-oriented or product-oriented views towards the assessment and writing skill. given the need for more empirical support, this study is aimed at investigating the availability of bilingual dictionary use...

today, chronic viral hepatitis is considered as a public health problem in the world. totally, 5% of the world population, especially in asia and africa suffer from this problem. the prevalence of acute hepatitis in america is 0.1-0.2 percent, 50% of those with hepatitis c (hcv) and 5-10% of them with hepatitis b (hcv) develop chronic hepatitis. determining hbv and hcv genotypes is important to...

In the Sahelian zone of Ouaddaï in Chad, Balanites aegyptiaca (L.), Sclerocarya birrea (A. Rich.) and Ziziphus mauritiana Lam. are multipurpose woody species that found agroforestry land use systems contribute to nutrition, health economy local populations. The purpose study is assess natural regeneration population structure these view their domestication. was carried out ...

This paper discusses nonparametric kernel regression with the regressor being a d-dimensional β-null recurrent process in presence of conditional heteroscedasticity. We show that the mean function estimator is consistent with convergence rate √ n(T )hd, where n(T ) is the number of regenerations for a β-null recurrent process and the limiting distribution (with proper normalization) is normal. ...

Ammonium removal from aqueous solution by a natural ion-exchange resin was investigated by considering the factors affecting the ammonium-exchange capacity including the zeolites’ particle size, the loading flow rates and the impact of a number of regenerations upon the ion-exchange capacity. The resin column was exhausted by downflow at 10, 25, 50 and 75 bed volume (BV)/h, until effluent ammon...
