The coercivity Hc; of rapidly quenched Nd-Fe-B is linked to the multiphase structure of the alloys: high coercivities require the suppression of the &Nd solid solution and the exictence of the intergranular Nd-rich phase. In quarternary Pr-Fe-Co-B alloys H,i and the remanence J, depend in the same way on Co content as in the Nd-FeCo-B system. However, compared with rapidly quenched Nd-Co-B samp...
This research evaluated the effect of nitrogen fertilization (0, 161, 321.8, or 483 kg ha-1) on accumulation Fe, Cu, Zn, Mn, and B in banana plants cv. Williams two production cycles Uraba, Colombia. The micronutrient models for were obtained with a multivariate approach differences between cycles, using randomized complete block design repeated measurements over time. N doses greater Zn fruits...
The Shah-kuh granite batholith (South of Birjand), monozogranite and syenogranite composition, is located on the eastern edge of the Lut block and consists mainly of plagioclase, alkali-feldspar and quartz associated with biotite and tourmaline. The predominant texture of the monozogranite and syenogranite unit is granular to porphyric and granular to micrographic, respectively. Metapelite rock...
