The B.E. Journal of Economic Analysis & Policy, 2006 Informal lending and savings institutions exist around the world, and often include regular door-to-door deposit collection of cash. Some banks have adopted similar services in order to expand access to banking services in areas that lack physical branches.

Porous Al Current Collector for Dendrite-Free Na Metal Anodes.
Nano letters (Print), 2017Na-based batteries are proposed as promising energy storage candidates for beyond Li-ion technology due to the higher natural earth of Na metal. For its high capacity and low potential, Na metal may carve itself a niche when directly used as anodes ...

The Art Collector and the Tax Collector
Art Journal, 1973Rising prices at auction houses and galleries for the past few years have dampened the acquisitive desires of some collectors, but notable works of art offered for sale to reap these financial rewards have proved irresistable to others. The motives of the American collectors enjoying the fruits of our era are as diverse as their collections, and the ...

fessional fashion—those whisperings that lead students to stray into law or business—the medical student remains a select member of a special society. The gauntlet each student runs to attain that society is formida- ble. Few men and women are so tested and measured.
