high through put sequencing of single nucleotide polymorphisms (snp) has revolutionized the fine scale analysis of the population structure in different species. various methods have been proposed and used for the study of population structure using whole-genome marker data that each has advantages and disadvantages with respect to their characteristics. super paramagnetic clustering (spc) whic...

Some calculations of the electric field derivative of the spin-spin coupling constant on molecules in the series CH3F, CH3Cl, CH3Br, CH3I, CH4, CH3Li, CH3Na and CH3K have been presented. The data is broken down into the 4 terms of the Ramsey theory: Fermi contact (FC); diamagnetic spin-orbit (DSO); paramagnetic spinorbit (PSO) and spin-dipolar (SD). The FC term is seen to dominate all the calcu...

The diamagnetism of biological tissues reduces the homogeneity of the magnetic field and may limit the number of samples in multi-sample gradient-recalled echo (GRE) experiments. This study aims to 1) evaluate the magnetic field distortions and signal loss artifacts in GRE images of proximal water samples, and 2) develop a passive shimming device to overcome this limitation. The magnetic field ...

in the current investigation, fe3o4 water-based nanofluids were synthesized to examine the effect of an alternative 3-d external magnetic field on its thermal behavioral pattern. a solvothermal method was used to prepare the magnetite nanoparticles. to characterize the nanoparticles, the study employed transmission electron microscopy, x-ray diffraction, fourier transform infrared spectroscopy,...

This study aims to develop a comprehensive process evaluate the leaching behavior of 3D-printed nanocomposite samples as candidate materials for potential use in wearable devices. The involves immersion test coupons, produced via Fused Filament Fabrication (FFF), into artificial sweat and deionized water controlled environment provided by dissolution apparatus. Three distinct filaments were use...

trichomoniasis, the most widespread sexually transmitted disease is caused by trichomonas vaginalis. this parasite is site specific for the genitourinary tract and recruitment of macrophages as well as polymorphonuclear nutrophils (pmn) to the site of infection is the first line of defense as a component of non-specific resistance and immunity. in this study, balb/c mice were infected with 10 i...

Several reviews concerning the EPR of the paramagnetic transition-metal ions in crystals are now available, either as periodic reports published in the Magnetic Resonance Review, or in books [1,2,3] and review papers [4, 5]. Such paramagnetic centers are usually observed in the as grown crystals, the paramagnetic state being the normal valency state of the impurity in the crystal-host lattice. ...
