In a recent experiment by Krimmel et al. [Phys. Rev. Lett. 78, 3880 (1997)], the critical behavior of FeCo near a (001) surface was studied by x-ray scattering. Here the experimental data are reanalyzed, taking into account recent theoretical results on order-parameter profiles in the crossover regime between ordinary and normal transitions. Excellent agreement between theoretical expectations ...

This study reveals the effect of TiB₂ particles on the mechanical and tribological properties of Fe₃Al-TiB₂ composite coatings against an alumina counterpart. The feedstock was produced by milling Fe₃Al and TiB₂ powders in a high energy ball mill. The high-velocity oxy-fuel (HVOF) technique was used to deposit the feedstock powder on a steel substrate. The effect of TiB₂ addition on mechanical ...

the 440 fertile eggs, in a completely randomized design were divided into 11 treatments with four replicatesand 10 eggs per each replicate. treatments including: (t1; control; without injection), (t2; injected with 0.3ml saline 9.0%; sham control), (t3, t4 and t5) 25, 75, 125 ppm fe-nano, (t6, t7 and t8) 50, 100, 150 ppmfe-nano-alimet chelate, (t9, t10 and t11) 50, 100, 150 ppm fe-aliment chela...

Roots of Fe-sufficient and Fe-Deficient pea (Pisum sativum L.) were studied to determine the effect of Fe-deficiency on the activity of the root-cell plasmalemma Fe(2+) transport protein. Rates of Fe(III) reduction and short-term Fe(2+) influx were sequentially determined in excised primary lateral roots using Fe(III)-ethylene-diaminetetraacetic acid (Fe[III]-EDTA). Since the extracellular Fe(2...
