industries, its nuclear properties in the pure metallic form make it highly desirable for nuclear applications. Zr is highly corrosion resistant and has a high melting point (2128 K) with a low thermal neutron absorption cross-section of Zr T = 0.18 b, which is significantly smaller than that of hafnium Hf T =115 b) (Speer, 1982), an element that coexists with Zr in nature. This makes Zr ideal ...

We have combined electron heating experiments and noise thermometry to perform quantitative measurements of the thermopower in mesoscopic samples. This new measuring technique allows us to detect finite size effects in the thermopower of narrow AuFe wires with an Fe concentration ranging from 50 to 3000 ppm. The size effects emerge when reducing the width of the wires below .300 nm and may be r...

An experiment was conducted to determine the effect of high dietary intakes of Zn and Cu and their combination on growth performance of weanling pigs with diverse health status and management strategies. Twelve experiment stations cooperated and used a total of 1,356 pigs that averaged 6.55 kg BW and 22.2 d age at weaning. The four dietary treatments, all of which met or exceeded NRC requiremen...

Introduction: The concentration of H2O in the Martian mantle is of importance to understanding the dynamics of convection, the spatial and temporal occurrence of partial melting, and the history of volatile fluxes from the interior to the surface, but is subject to considerable uncertainty and vigorous debate [1-6] Simulation of the cosmochemical and accretionary origin of Mars suggests an init...

Elevated CO2 (eCO2) has been reported to cause mineral losses in several important food crops such as soybean (Glycine max L.) and common bean (Phaseolus vulgaris L.). In addition, more than 30% of the world’s arable land is calcareous, leading iron (Fe) deficiency chlorosis lower Fe levels plant tissues. We hypothesize that there will be combinatorial effects eCO2 on dynamics these at a morpho...

The present study investigated the hydrogen-related fracture behavior of specimens with different stress concentration factors through microstructure observation, finite element (FE) simulation, and digital image correlation (DIC) analysis. alloy studied was a simple model (Fe-0.2C binary alloy) fully martensite structure. When hydrogen content large (2.21 mass ppm (121 at ppm)), crack initiati...
