Naomi Block Manners Stern collection of Eleanor Roosevelt correspondence undated, 1941-1962, 1972, 1974, 1976, 1984, 2003

This collection is mainly composed of correspondence between Ms. Stern and Mrs. Roosevelt, spanning the years from their first acquaintance in 1941 to Mrs. Roosevelt's decease in 1962. Letters that hold particular interest concern Ms. Stern's experience at the Summer Student Leadership Institute, and the White House. Additional material in the collection encompasses articles, newsclippings, programs, press releases, and photographs. The articles and newsclippings folder contains information pertaining to Ms. Stern's college career, the first Summer Student Leadership Institute, Mrs. Roosevelt's talk at Community Day, National Youth Association, and a donation of an ambulance to the war effort by Hunter college students. Naomi Block Manners Stern personal folder contains an article Naomi Block wrote in her college magazine, "Echo," describing her perceptions of President Roosevelt and Prime Minister Winston Churchill during her first visit at the White House. Also included is her graduation program, listing Mrs. Roosevelt as the main speaker, a commemoration of President Roosevelt in 1972 in which Ms. Stern took part, an article and press release describing Ms. Stern's career at Revlon, and a 2003 written summary of Ms. Stern's relationship with Mrs. Roosevelt. Photographs were taken by Naomi Block and others at the Summer Leadership Institute in 1941 portray identified fellow students, Mrs. Roosevelt, James Roosevelt, the Roosevelt home in Campobello, and Felix Frankfurter.

Rapid quenching and glass formation in chalcogenide glasses: Preparation and properties of Ge-As-Te glasses over an extended composition ranges

In Ge-As-Te system, the glass forming region determined by normal melt quenching method has two regions (GFR I and GFR II) separated by few compositions gap. With a simple laboratory built twin roller apparatus, we have succeeded in preparing Ge7.5AsxTe92.5-x glasses over extended composition ranges. A distinct change in T-g is observed at x = 40, exactly at which the separation of the glass forming regions occur indicating the changes in the connectivity and the rigidity of the structural network. The maximum observed in glass transition (T-g) at x = 55 corresponding to the average coordination number (Z(av)) = 2.70 is an evidence for the shift of the rigidity percolation threshold (RPT) from Z(av) = 2.40 as predicted by the recent theories. The glass forming tendency (K-gl) and Delta T (=T-c-T-g) is low for the glasses in the GFR I and high for the glasses in the GFR II.

Novel dielectric properties of glasses prepared by quenching melts of Bisingle bondCasingle bondSrsingle bondCusingle bondO cuprates

Glasses, prepared from the melts of Bi2(Ca, Sr)n+1 CunO2n+4 (n=1,2 and 3) have been characterized by various techniques. These glasses exhibit relatively high dielectric constants, high electrical conductivity, a ferroelectric-like dielectric hysteresis loop and pyroelectric effect at 300K. They also show weak microwave absorption at 77K.

Dielectric properties of glasses prepared by quenching melts of superconducting Bi‐Ca‐Sr‐Cu‐O cuprates

Glasses obtained from quenching melts of superconducting bismuth cuprates of the formula Bi2(Ca,Sr)n+1CunO2n+4 with n=1 and 3 exhibit novel dielectric properties. They possess relatively high dielectric constants as well as high electrical conductivity. The novel dielectric properties of these cuprate glasses are likely to be of electronic origin. They exhibit a weak microwave absorption due to the presence of microcrystallites.

Electron-beam melting and centrifugal splat-quenching technique for rapid solidification of titanium alloys

An electron-beam melting and centrifugal splat-quenching technique for the production of microflakes of Ti-6A1-4V (wt%) alloy quenched at an average cooling rate of about 105 K sec–1 is described. The effect of substrate angle on the shape, size, microstructure and average cooling rate of the flakes of major sieve fractions is discussed. Morphologies of particles of minor sieve fractions are dealt with briefly.

Quenching of gA in the nuclear medium

The numerical values of gA are evaluated using quantum-chromodynamic sum rules. The nuclear medium effects are taken into account by modifying the chiral symmetry breaking correlation, . Our results indicate a quenching of gA in a nuclear medium. The physical reasons for this fundamental quenching are noted to be the same for the effective mass of the nucleon bound in a nucleus being less than its free space value.
