The aim of the paper is to investigate effects of long term x-ray exposure on the human lymphocyte, reactive lymphocyte parameters and morphology of lymphocytes in x-ray technicians at Kirkuk hospitals. The study included 54 apparently healthy male x-ray technicians were matched with another 54 apparently healthy control to show any alteration in the lymphocytes, reactive lymphocytes and morpho...
Considering time-harmonic optical fields, we put forward the complex helicity and its alternating flow, together with their conservation equation: theorem. Its imaginary part constitutes a novel law that rules build-up of what establish as reactive through zero time-average flow. associated flow Poynting momentum accounts for accretion power are illustrated in two paradigmatic systems: evanesce...
Reactive oxygen species (ROS)plays an important role in sperm motility. The physiological generation at low concentration induces beneficial effects on sperm functions and plays a significant role in sperm metabolism. Meanwhile, the excessive generation of reactive oxygen species can overwhelm protective mechanism and triggers changes in lipid and protein layers of sperm plasma membrane, which ...
Usually, the conventional droop methods is utilized for control of autonomous micro-grids. In islanded micro-grids (MG), due to the effects of mismatch in line impedance, the reactive power can't share by using the conventional droop method. In this paper, a method is proposed to improve reactive power sharing. In this method, the micro-sources are acted with P-w & Q-E droop characteristics, an...
Abstract During normal cellular activities Reactive Oxygen Species (ROS) and Reactive Nitrogen Species (RNS) are produced. In addition to beneficial functions they play a critical role in cell death and prevent apoptosis. Every cell is equipped with an extensive antioxidant defense system to combat the excessive production of active radicals. Oxidative stress occurs with destruction of cellu...
