8Separation of rare earth elements from sulfate leach liquor by heterocyclic nitrogen compound显示文摘Separation of rare earth elements by solvent extraction has actually been widely used in various fields from analytical chemistry to hydrometallurgy. A representative ore sample obtained from Kadabora Batholiths-Eastern Desert of Egypt, containing the multiple oxides rare earth minerals: Samarskite, Fergusonite, Betafite, and Pyrochlore, was subjected to sulfuric acid leaching. Different sets of equilibrium loading experiments were carried out on a bench scale for the extraction of rare earths (cerium and yttrium) from the sulfate leach liquor using 8,9-dihydro[1,2,4]triazolo[1,5-a]quinazolin-6(7H)-one {TQ} dissolved in methylene chloride. Stripping was carried out by 20% sodium hydroxide. A rare earth cake was produced by oxalic acid precipitation. Its purity reached 87.3%.GHADA M. Mahmoud NABIL T. El Hazek AHMAD M. Farag OMNEYA M.

13Novel Sustainable Cellulose Acetate Based Biosensor for Glucose Detection显示文摘In this study,green zinc oxide(ZnO)/polypyrrole(Ppy)/cellulose acetate(CA)film has been synthesized via solvent casting.This film was used as supporting material for glucose oxidase(GOx)to sensitize a glucose biosensor.ZnO nanoparticles have been prepared via the green route using olive leaves extract as a reductant.ZnO/Ppy nanocomposite has been synthesized by a simple in-situ chemical oxidative polymerization of pyrrole(Py)monomer using ferric chloride(FeCl3)as an oxidizing agent.The produced materials and the composite films were characterized using X-ray diffraction analysis(XRD),scanning electron microscope(SEM),Fourier transform infrared(FTIR)and thermogravimetric analysis(TGA).Glucose oxidase was successfully immobilized on the surface of the prepared film and then ZnO/Ppy/CA/GOx composite was sputtered with platinum electrode for the current determination at different initial concentrations of glucose.Current measurements proved the suitability and the high sensitivity of the constructed biosensor for the detection of glucose levels in different samples.The performance of the prepared biosensor has been assessed by measuring and comparing glucose concentrations up to 800 ppm.The results affirmed the reliability of the developed biosensor towards real samples which suggests the wide-scale application of the proposed biosensor.M.F.Elkady E.M.El-Sayed Mahmoud Samy Omneya A.Koriem H.Shokry Hassan 2024Journal of Renewable Materials2024,12,2:0
14Efect of early feeding practices and eating behaviors on body composition in primary school children显示文摘Background Understanding children’s feeding practices and eating behaviors is important to determine etiology of childhood obesity.This study aimed to explore the relationship between early feeding practices,eating behavior and body composition among primary school children.Methods The data were collected from 403 primary school children.They were administered structured questionnaire,including sociodemographic characteristics,early feeding practices and Child’s Eating Behavior Questionnaire.Anthropometric and blood pressure(BP)measurements were performed.Results Children with obesity and overweight showed higher food approach subscales and lower food avoidance subscales compared to a healthy and underweight child.Children who were exclusively or predominantly breast fed during the frst 6 months had the lowest scores for the food approach subscales,food responsiveness(FR)and emotional overeating(EOE)and had the highest scores for the food avoidance subscales,satiety responsiveness(SR)and emotional under eating(EUE).Children who were introduced solid food after 6 months showed lower scores for FR,enjoyment of food and EOE but scored highest for SR,slowness in eating(SE)and EUE.All anthropometric measurements were positively correlated with all food approach subscales and negatively with SE,SR and food fussiness.All food approach subscales were positively correlated with BP percentiles.All food avoidance subscales were negatively correlated with both BP percentiles,except for EUE,which was negatively correlated with diastolic BP percentile only.Age,SR,SE and FR were predictors for child body mass index.Conclusion Early feeding practices and eating behavior are considered as prevention approaches for obesity.Omneya Magdy Omar Mohamed Naguib Massoud Afaf Gaber Ibrahim Nada Atef Khalaf 2022World Journal of Pediatrics2022,18,9:0
