A field experim.nt was conducted in 2009 and 2010 growing seasons, to study the effect of foliar application of iron-chelated ＂Fe-EDTA＂ at concentration 0, 100 and 200 m./L on the seasonal dynam.c of m.neral com.osition of N, P, K, Fe and Zn in petioles and berries of Halwani Lebanon and Kam.li grape cultivars, grown on a calcareous soil in m.sul region, Iraq. The results revealed that the foliar application of 200 m. Fe/L caused a significant increase of N, P, K, Fe and Zn concentrations in petioles and berries com.ared with the control for both seasons. Additionally, the N, P, K, Fe and Zn concentration in petioles were high at the beginning of the growth season, whereas, decrease towards in the end of the growth season in both cultivars and seasons. While the N, P, K, Fe and Zn in berry content was increased towards from.berry set to veraison and ripening stage in both cultivars and seasons. So there are various elem.nt contents in the cultivars.

The paper investigates the num.rical solution of the m.gnetohydrodynam.cs (m.D) boundary layer flow of non-Newtonian Casson fluid on a m.ving wedge with heat and m.ss transfer. The effects of therm.l diffusion and diffusion therm. with induced m.gnetic field are taken in consideration. The governing partial differential equations are transform.d into nonlinear ordinary differential equations by applying the sim.larity transform.tion and solved num.rically by using finite difference m.thod (FDm.. The effects of various governing param.ters, on the velocity, tem.erature and concentration are displayed through graphs and discussed num.rically. In order to verify the accuracy of the present results, we have com.ared these results with the analytical solutions by using the differential transform.m.thod (DTm.. It is observed that this approxim.te num.rical solution is in good agreem.nt with the analytical solution. Furtherm.re, com.arisons of the present results with previously published work show that the present results have high accuracy.

Background: At the beginning of the COVID-19 pandemic, some reports demonstrated that children are at lower risk of infection. Though, with the growing transmission of the virus, it has been illustrated that it can infect children. Nevertheless, the features and outcomes of COVID-19 infection in children are still unclear. Objective: This study aims to describe the clinical characters and outcomes of children infected with COVID-19 and admitted to a hospital in Saudi Arabia. Design and Setting: This is a retrospective study that was carried out in Imam Abdulrahman Al Faisal Hospital in Riyadh, Saudi Arabia, by collecting data from patients’ records of children who were admitted to the hospital from March to July 2020. The collected data included information on the age and gender of the children, as well as their clinical course during hospitalization. Results: Thirty-three patients were included;39.4% of the children aged less than one year, 51.5% were males. Asthma occurred in 15.2% of patients. Asthma (p-valuem.l
