The present study aimed to determine the genetic divergence of seven maize genotypes (Al-Maha, Sumer, Al-Fajr, Baghdad, 5018, 4 × 1 single hybrid, and 2 hybrid) under two varied levels nitrogen fertilization (92 276 kg N ha-1). experiment occurred in 2022 a randomized complete block design (RCBD) with split-plot arrangement three replications at College Agricultural Engineering Sciences, Univer...

the exposure to electromagnetic field emitted by mobile telephones is increasing rapidly worldwide that causes side effects, including thermal and non thermal side effects. ear proximity to electromagnetic source may lead to greater damage and side effects, including hearing loss. this study was performed to assess the chronic effect of exposure to electromagnetic field of mobile telephones on ...

introduction: to reduce incidence of residual cholesteatoma following ear surgery; and to reduce the need for second look “open” mastoidectomy using endoscopic mastoidotomy. ten-year retrospective chart review of 249 primary cholesteatoma cases (1994-2004) with a minimum follow-up of two years.  the first objective was to evaluate the effectiveness of otoendoscopy in reducing the incidence of “...

The experiment was carried out at the “La María” Campus of State Technical University Quevedo, located in Mocache canton, province Los Ríos. This consisted establishment experimental lots simple maize hybrid called “Centella”, classified as high yielding and medium segmentation, subjected to different planting densities, which corresponded following treatments: T1 (60 x 25 cm), T2 (70 cm) T3 (8...

The canonical correlation analysis has been successfully used in many areas aiming to extract important information from a pair of data sets. Thus, the objective this work was determine sample size (number plants) required estimate correlations corn characteristics. Six characteristics were measured 361, 373, and 416 plants, respectively, single, three-way double cross hybrids 2008/2009 crop ye...

the aim of this study was to determine the anatomical features of the auditory ossicles in rat. twenty temporal bones from 10 adult rats were used. the features of the ossicles were assessed with an ocular micrometer and photographed by a stereomicroscope. finally, all data were evaluated and analysed using the sigma statt software. temporal bone in rat was similar to other animals consists of ...

A standing wave tube apparatus was used to determine the biophysical basis of underwater hearing sensitivity in 3 species of Rana and in Xenopus laevis. A speaker inside the base of a vertical, water-filled 3 m steel pipe produced standing waves. Pressure and particle motion were measured with a hydrophone and geophone respectively and were spatially 90 degrees out of phase along the length of ...

The ear leaf is one of the most important leaves in maize (Zea mays); it affects plant morphology and yield. To better understand its genetic basis, we examined ear leaf length, ear leaf width, and ear leaf area for quantitative trait locus (QTL) mapping in a recombinant inbred line population under two nitrogen regimes. Nine QTLs, on chromosomes 1 (one), 2 (one), 3 (one), 4 (three), 7 (one), a...

Maize (Zea mays L.) is an important food security crop in Ethiopia. However, low soil fertility and the use of haphazard nitrogen (N) fertilizer with little attention to rate timing N application constrain productivity. Therefore, field experiments were conducted during 2019 2020 cropping seasons investigate response maize different rates timings. The treatments consisted six (0, 23, 46, 69, 92...

A field investigation was conducted in Kharif (2022), at a Crop Research Farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P). To study the “ Influence foliar application zinc on growth yield pearl millet (Pennisetum glaucum L.) varieties.” An experiment laid out Randomized Block Design with ten treatments each replicated thrice. The consist three different...
