صخلملا The aim of this study isto examine whether radiofrequency (RF) used in cellular phone communications at a specific absorption rate (SAR) less than 1.2 w/kg could increase the spontaneous rate of sister chromatid exchanges (SCE) or elicit alterations both in the cell replication index (CRI) and mitotic index (MI) in human peripheral blood lymphocytes. Whole blood samples were obtained fro...
This study investigated the structure, mineralogical specifics and chemical composition, of a natural and modified diatomite ore, which obtained from the Aktyubinsk /Kazakhstan deposits by using SEM, XRF, XRD, FTIR, TGA and SDTA. Three modified forms of diatomite’s were prepared by calcinations at 900C and/or calcinations and acidification by 0.5 N HCl (D, D-HCl, D-900 and D-900-HCl). The iron(...
Here, the co-managment of municipal wastewater (MWW) and acid mine drainage (AMD) is proposed, where recovered low-value phosphorus from MWW used for treatment AMD. Specifically, was treated using calcium hydroxide (Ca(OH)2), a low-cost readily available material, with ammonia content being greatly reduced (89%) through stripping phosphates practically eliminated (>99%). The in form phosphate (...
Halloysite nanotubes (HNTs) are proven nanocontainers and nanocarriers. Silver nitrate (Ag) zinc sulfate nanoparticles (Zn) known for their antimicrobial properties. This study incorporated Ag Zn-coated HNTs in electrospun polylactic acid (PLA) nanofiber composite. An efficient 'green' method of coating Zn on the HNT surface was used to metal coat HNTs. The resulting PLA fibers were characteriz...
A calibration procedure for the detection efficiency of energy dispersive X-ray spectrometers (EDS) used in combination with scanning electron microscopy (SEM) for standardless electron probe microanalysis (EPMA) is presented. The procedure is based on the comparison of X-ray spectra from a reference material (RM) measured with the EDS to be calibrated and a reference EDS. The RM is certified b...
Using the stones to make tools and vessels dated back to Paleolithic and Neolithic periods. Stones so called soft stones, along with the alabaster, are one of the most famous stones that have been used to produce vessel in Near East, where they are in use currently in different applications. Soft stone vessels reach to highest level of flourishing during the Bronze Age and its geographical exch...
An electron microprobe is an electron microscope designed for the non-destructive x-ray microanalysis and imaging of solid materials. It is essentially a hybrid instrument combining the capabilities of both the scanning electron microscope (SEM) and an x-ray fluorescence spectrometer (XRF), with the added features of fine-spot focusing (~ 1 micrometer), optical microscope imaging, and precision...
