Considering nutrient delivery and micronutrient use efficiency problems, mesoporous nanosilica (mNs) reduced graphene oxide (rGO)-based iron zinc nanocomposites were formulated. Prepared characterized for FTIR spectroscopy, XRD, FE-SEM, HR-TEM, AAS to examine surface functional groups, morphology, structural composition. XRD spectrum confirmation with SAED image of confirms the polycrystalline ...

This study was carried out to examine heavy metals concentration in water and sediment of upstream and downstream of the entry of the sewage to the Tembi River, Iran. Samples were collected from upstream and downstream and were analyzed for Cd, Cr, Cu, Fe, Pb, Ni, and Zn by atomic absorption spectrophotometer. The results indicated that the average concentration of the metals in water and sedim...

Ground water pollution causes adverse damage to soil, plants, human and animals at the same time spreads serious diseases. Ground water pollution can also cause biochemical effects such as inhibition of enzymes, genetic damage, and hypertension etc due to higher concentration of trace metals in the ground water. The present investigation is directed towards analysis of major metal ion concentra...

Heavy metal concentrations and magnetic susceptibility of sediment samples were analyzed as indicators of urban and industrial contamination in Anzali wetland in Gilan, Iran. The aim was to investigate the suitability of magnetic properties measurements for indicating heavy metal pollution. The concentration of six heavy metals (Ni, Cr, Cd, Zn, Fe, and Pb) was determined in different depths of ...

An Egyptian, plant pathogenic Fusarium solani isolate was grown on cobalt concentrations of 0, 50, 200, 500, 800, and 1000 ppm. The isolate survived concentrations up to 800 ppm, however failed to grow at 1000 ppm. Morphology and elemental analysis of the isolate under the investigated Co concentrations were studied using Scanning electron microscopy (SEM) and energy dispersive X-ray microanaly...

A series of five experiments was conducted to evaluate and investigate mode of transfer of an amino acid chelated iron fed to the sow as a hematinic for the baby pig. In the first experiment, >3,000 ppm iron (Fe) were provided to 1A the sows daily as the amino acid chelate (FeP) from late gestation through 3 weeks of lactation. Mean hemoglobin (Hb) among pigs of FeP-fed sows was 8.5g/dl by 2 we...

We conducted two trials (n = 144 and 96) to evaluate the response of feeding either ZnSO4 x H2O or a zinc-lysine complex (ZnLys) in combination with various lysine levels on growth performance, liver, kidney, and 10th rib Zn concentration, serum Zn humoral immune response and absorption of Zn (chromic oxide method) of young pigs. The following treatments were started after a 7-d postweaning adj...

Liquid pig feed (LPF) and skimmed milk (SM) acidified to pH 4 with lactic or hydrochloric acid (HCl) were treated with 0, 2.5, 5. 12.5, 25 or 50 ppm Cu and challenged with 10 c.f.u ml Salmonella Typhimurium DT104:30. The decimal reduction time (D) was determined by enumeration of viable Salmonellae at appropriate time intervals after inoculation. Additional SM samples, acidified to pH 2.5 with ...

Murrell and Burnett (M-B) ( 1982) reported that oldhamite (CaS) is the primary host phase ofU and Th in the E6 chondrites. E-chondrite Th/U values were all cosmic, indicating a lack of Th-U fractionation in both oldhamite and in the bulk meteorites. In Khairpur (E6), they attributed excess fossil fission tracks to the presence of Pu in oldhamite. Rare earth (REE) enrichments were inferred for a...
