in order to study of yield, growth index and physiological traits in spring sugar beet genotypes with delayed planting date, a field experiment was carried out in chenaran in khorasan razavi province in the east of iran in 2008 cropping season. for this experiment a complete randomized block design with 4 replications and 6 treatments was used. the experimental treatments were six improved vari...

In this paper, we study some growth properties of entire functions represented by a vector valued Dirichlet series on the basis of generalized relative Ritt order and generalized relative Ritt lower order.

salinity is one of the most important limiting factors for crops, because of most agronomic and horticultural crops are sensitive to salinity. on the other hands, considerable lands of the world were affected by salinity and they are increasing day by day. an experiment was conducted with five levels of irrigation water salinity in soilless culture and greenhouse condition to evaluate the effec...

Methylene blue is widely used in various industrial branches. Due to insufficient treatment, its occurrence in wastewater is frequently detected, which may result in serious environment problems to aquatic organisms. Hydroponic experiments were conducted with rice seedlings (Oryza sativa L. cv. XZX 45) exposed to methylene blue to determine the effective concentration using relative gr...

We study certain groups of isometries of hyperbolic space (including certain hyperbolic Coxeter groups) and normal subgroups with quotient Zν , ν ≥ 1. We show that the associated relative growth series are not rational. This extends results obtained by Grigorchuk and de la Harpe for free groups and Pollicott and the author for surface groups.

BACKGROUND Living in socioeconomically disadvantaged areas is associated with increased -childhood mortality risks. As city living becomes the predominant social context in low- and middle-income countries, the resulting rapid urbanization together with the poor economic circumstances of these countries greatly increases the risks of mortality for children < 5 years of age (under-5 mortality). ...

The rate of growth of the partial quotients of an irrational number is studied relative to the rate of approximation of the number by its convergents. The focus is on the Hausdorff dimension of exceptional sets on which different growth rates are achieved. In this note we look at the rate of growth of the partial quotients ai of the irrational number x = [a1, a2, . . . ] = 1 a1 + 1 a2 + 1 a3 + ...

This vignette demonstrates an analysis of the relative stabilities of 24 carboxylases from model organisms that grow optimally at different temperatures. In the chemical thermodynamic model, changes in both temperature and oxidation potential influence the relative stabilities of the proteins with an overall progression that fits with the growth temperatures of the organisms. The calculations s...
