The compositions and structures of thermodynamically stable or metastable precipitations in binary Mg-X (X=Sn, Y, Sc, Ag) alloys are predicted using ab-initio evolutionary algorithm. The geometry optimizations of the predicted intermetallic compounds are carried out in the framework of density functional theory (DFT) [1]. A complete list of the optimized crystallographic information (in cif for...

Light microscopic examination of the kidneys in 170 patients with multiple myeloma revealed three from patients without diabetes with glomerular nodules that were indistinguishable from those of diabetic glomerular sclerosis. Electron microscopic studies showed the nodules to be deposits of fine-grained material that corresponded to precipitations of protein but lacked the basement-membrane-lik...

Growth ring analysis on silicified coniferous woods from the Missão Velha Formation (Araripe Basin - Brazil) has yielded important information about periodicity of wood production during the Early Cretaceous in the equatorial belt. Despite warm temperatures, dendrological data indicate that the climate was characterized by cyclical alternation of dry and rainy periods influenced by cyclical pre...

The conjugate of folic acid (pteroylglutamic acid, vitamin B,) in yeast was isolated by Pfiffner et al. (1) and determined to be pteroylhexaglutamyl glutamate (2). Recently this group has published details of the concentration of the conjugate (3). The present paper describes a simple method for producing a concentration of the conjugate of from 40to loo-fold by differential extraction of colum...

Cyclic stress strain curves (CSSC) response of Al-2024 Annealed condition was conducted under symmetric tension-compression at room temperature and constant frequency, using a servo-hydraulic testing machine, to study the effect of cooling rate on cyclic stress strain curves (CSSC) response. The fatigue response of Al-2024 alloy was evaluated macroscopically in terms of cyclic stress strain res...
