Tassel traits are important in maize breeding programs aiming to reduce the size and number of branches and maintain satisfactory pollen production in order to increase grain yield. The objectives of this study were to determine the sample size (number of tassels) required to estimate the mean values for tassel traits in maize genotypes and to verify the variability of sample size among genotyp...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
Background: Renal artery stenosis, which is defined as narrowing of one or both renal arteries or their branches, is one of the most common causes of secondary hypertension. The majority of renal vascular lesions show either fibromuscular dysplasia or atherosclerosis. Fibromuscular dysplasia is a common cause of renovascular hypertension in younger patients, and 90% of patients are young wome...
A single primary user cognitive radio system with multi-user diversity at the secondary users is considered where there is an interference constraint between secondary and primary users. The secondary user with the highest instantaneous SNR is selected for communication from a set of active users which also satisfies the interference constraint. The active number of secondary users is shown to ...
the research has been done for assessment of effects of different concentrations of indole-3-butyric acid (iba) on rhizogenesis of scions of c. phlomidis in 2010. the research has been done on randomized complete-blocks for five replications and three treatments with zero, 2000ppm and 3000pmm concentration. different characters such as number of root of each scion, length of root, length of ne...
The effect of Reynolds number on curves the transverse-only motion amplitude a circular cylinder with body mass m∗=0.935 and damping ratio ζ=0.00502 in turbulent flow range is investigated systematically using two-dimensional in-house code developed based lattice Boltzmann method. Large eddy simulation chosen as turbulence model to describe viscous, incompressible Newtonian fluid immersed bound...
