To evaluate the effect of water, tape drip and furrow irrigation methods on the performance components and features of Agria cultivar potato, an experiment was carried out in the agriculture faculty of Kermanshah. Repeated three times, this study was carried out in the form of full random blocks with the main factor of different amounts of irrigation water in three levels (50, 75, and100 percen...

A continuous record of atmospheric lead since 12,370 carbon-14 years before the present (14C yr BP) is preserved in a Swiss peat bog. Enhanced fluxes caused by climate changes reached their maxima 10, 590 (14)C yr BP (Younger Dryas) and 8230 (14)C yr BP. Soil erosion caused by forest clearing and agricultural tillage increased lead deposition after 5320 (14)C yr BP. Increasing lead/scandium and...

In this talk, we discuss the maximum number of n × n pure imaginary quaternionic solutions to the Hurwitz matrix equations given by T i T * j + T j T Abstract Let T be a bounded linear operator on a complex Hilbert space H. For 0 ≤ q ≤ 1, the

BACKGROUND Vascular endothelial growth factor (VEGF) promotes angiogenesis, a mediator of disease progression in cervical cancer. Bevacizumab, a humanized anti-VEGF monoclonal antibody, has single-agent activity in previously treated, recurrent disease. Most patients in whom recurrent cervical cancer develops have previously received cisplatin with radiation therapy, which reduces the effective...

Plants of a single genotype of wild strawberry, Fragaria virginiana Duchesne, were grown with or without fertilizer in high (406 microeinsteins per square meter per second) and low (80 microeinsteins per square meter per second) light. High-light leaves were thicker than low-light leaves and had greater development of the mesophyll. Within a light level, high-nutrient leaves were thicker, but t...

introduction drought stress as the most important abiotic stress plays an important role in yield reduction of crops worldwide. considering the extends and problems caused by the moisture stress, agronomic and breeding strategies in reducing yield loss are essential. in this regard, the identification and selection of effective characteristics of wheat under drought stress in increasing yield, ...

From an analysis of trace element abundances in lunar soils, the influx of meteoritic mass into the lunar surface has recently been estimated by Keays et al. (1) as 3.8 X 10-9 gcm-2 yr-1 and later by Ganapathy et al. (2) as 4 X 10-9 g cm-2 yr-1. I shall show in this note that these numbers are in agreement with independent estimates of the mass distribution for cometary meteoroids. Using the re...

OBJECTIVE This study aimed to compare the effects of a low-intensity face-to-face therapy provided by a trained paediatrician to an intensive group therapy provided by a multidisciplinary team on the BMI of adolescents with obesity. METHODS This longitudinal cohort study included 233 adolescents aged 11-18 years (mean 13.1 ± 1.7 years). Patients and their parents choose either a low-intensity...

We have investigated the characteristics of a silicon oxynitride/silver/silicon oxynitride [SiON/Ag/SiON] multilayer passivation grown using a specially designed roll-to-roll [R2R] sputtering system on a flexible polyethersulfone substrate. Optical, structural, and surface properties of the R2R grown SiON/Ag/SiON multilayer were investigated as a function of the SiON thickness at a constant Ag ...
