Carnegie Observatories' Wendy Freedman On Hubble and Size of Universe
This spring, Director of the Carnegie Observatories Wendy Freedman spoke at the American Museum of Natural History's Hayden Planetarium about astronomer Edwin Hubble's discovery of the galaxies and the expansion of the universe, how astronomers measure vast distances, and how the Hubble Space Telescope is used to measure the size and age of the universe. Mike Shara, curator in the Department of Astrophysics, sat down with Freedman for an interview in the Hayden Planetarium to discuss the expansi
New Fossil Solves Puzzle of Mammalian Evolution
Paleontologists from the American Museum of Natural History and the Chinese Academy of Sciences announce the discovery of Liaoconodon hui, a complete fossil mammal from the Mesozoic found in China that includes the long-sought transitional middle ear.

Joseph Grenny spoke to Googlers in Mountain View on April 14, 2011 about the book he co-authored: Change Anything: The New Science of Personal Success. About Change Anything: "A stunning new approach to how individuals can not only change their lives for the better in the workplace, but also their lives away from the office, including (but not limited to) finding ways to improve one's working relationship with others, one's overall health, outlook on life, and so on. For example, why is it th

Investigation into the determination of arsenic by direct current plasma atomic emission spectromete
Improvements have been made on the currently available hydride generator system manufactured by SpectraMetrics Incorporated, because the system was found to be unsatisfactory with respect to the following: 1. the drying agent, anhydrous calcium chloride, 2. the special sample tube, 3. the direction of argon flow through the Buchner funnel when it came to dealing with real sample, that is, with reference only to aqueous extracts of soil samples. Changes that were made on the system included the r
Fimbriae of coprinus cinereus, schizophyllum commune and ustilago violacea = structural aspects and
Surface fibrils (fimbriae) have been observed on fungi from every major group. Fimbriae are thought to be involved in the following cell to cell interactions: conjugation, flocculation and adhesion. Several higher fungi exibit two other types of interactions: hyphal fusion (anastomosis) and clamp connection formation. As a prelude to examining the role of fimbriae in these processes, the fimbriae of two fungi that undergo these fusion events were examined. Electron microscopy studies revealed th
Effects of sample solvent composition and injection volume on chromatographic peak profiles of methy
The effects of sample solvent composition and the injection volume, on the chromatographic peak profiles of two carbamate derivatives, methyl 2-benzimidazolecarbamate (MBC) and 3-butyl-2,4-dioxo[1,2-a]-s-triazinobenzimidazole (STB), were studied using reverse phase high performance liquid chromatograph. The study examined the effects of acetonitrile percentage in the sample solvent from 5 to 50%, effects of methanol percentage from 5 to 50%, effects of pH increase from 4.42 to 9.10, and effect o

An analysis of decoupling procedures in generating thermal Green's functions of O([lambda]â ´) by
The Zubarev equation of motion method has been applied to an anharmonic crystal of O( ,,4). All possible decoupling schemes have been interpreted in order to determine finite temperature expressions for the one phonon Green's function (and self energy) to 0()\4) for a crystal in which every atom is on a site of inversion symmetry. In order to provide a check of these results, the Helmholtz free energy expressions derived from the self energy expressions, have been shown to agree in the high temp

Enantiodivergent chemoenzymatic synthesis of codeine
The present thesis describes our latest results in the chemistry of morphine alkaloids. An enantiodivergent synthesis of codeine utilizing a cis-cyclohexadiene diol derived from microbial whole cell oxidation of ~-bromoethylbenzene,as starting material is discussed. The total synthesis of (+)-codeine in 14 steps featuring a Mitsunobu inversion and two intramolecular Heck cyclizations is presented. Investigation of a regioselective nucleophilic opening of a homochiral vinyl oxirane, which led to

ANSO 103-01, Introduction to Anthropology, Spring 2002
We enter the world with the marvelous capacity to live any one of a thousand different kinds of lives, as the anthropologist, Geertz, says. Nevertheless once we begin to live that life that is to become ours, we often live it with the amazing conviction that it is the best and possibly only way to live. Those other lives that could possibly have been ours are also lived with equal conviction. Many of those thousand different kinds of lives are lived next door when society sees "race"1, gender, a
