The significant accumulation of Pb from anthropogenic activities threatens environmental ecosystems. In the environment, iron oxides are one main carriers Pb. Thus, redox cycling oxides, which is due to biotic and abiotic pathways, leads their dissolution or transformation, controls fate However, a knowledge gap exists on bioreduction in Pb-bearing ferrihydrites, secondary-mineral precipitation...

the fluid flow and heat transfer in a three-dimensional microchannel filled with al2o3- water nanofluid is numerically investigated. the hybrid scheme is used to discretize the convection terms and simpler algorithm is adopted to couple the velocity and pressure field in the momentum equations. the thermal and flow fields were analyzed using different volume fractions of nanoparticles and diffe...

Figure 1: Course of the common, deep (blue) and superficial peroneal nerve, sites of stimulation for motor nerve conduction studies are shown by green discs. Figure 1 Textbooks of neurology are just like cookery or gardening books. It is all so easy on paper. With a good working knowledge of neurological anatomy, it seems, almost any problem can be precisely localised. A couple of of hours yomp...

background: pregnant women take iron supplements in order to prevent iron deficiency anemia which may have undesirable effects for both the mother and fetus. this study aimed to compare the daily and intermittent dose of iron supplementation in blood and iron indices in healthy pregnant women.methods: in this clinical trial study, 145 healthy pregnant women were selected with hbx0511g%. the par...

This work examines the excessive absorption and anomalous cooling phenomena reported in laser-induced incandescence measurements on metal nanoparticles by considering effects of aggregate structure sintering. Experimental investigations are conducted iron molybdenum aerosols, which have different melting points, thus respond differently to laser pulse. Although aggregation enhances cross-sectio...

In this study, iron oxide cocatalysts were deposited on the surface of ZnO nanostructures by a simple “drop, evaporation, calcination” method. Different deposition concentrations studied, allowing to extend photocatalyst absorption spectral range from UV visible light, improving photocatalytic efficiency under natural sunlight. An optimal concentration 0.06% molar percentage against zinc led im...

The aim of the project is to detect and quantify the egect of sea state on the wind stress. An overview of the basic theory of wind stress in the surface layer is provided, along with a more detailed description of the inertial dissipation method which is used to obtain stress estimates for this study. Wind stress measurements by other researchers illustrate the large scatter which seems to be ...
