To investigate the dynamic recrystallization (DRX) behavior of as-cast Fe-20Cr-5.5Al-0.64La stainless steel, a series compression tests were carried out on Gleeble-3500 thermal simulator in temperature range 1000~1150 °C and strain rate 0.001~1 s−1. The true stress-true curves obtained their characteristics analyzed. Using regression analysis, apparent activation energy for steel was estimated ...

Strains in thermally grown oxides have been measured in-situ, as the oxides develop and evolve. Extensive data have been acquired from oxides grown in air at elevated temperatures on different model alloys that form Al2O3. Using synchrotron x-rays at the Advanced Photon Source (Beamline 12BM, Argonne National Laboratory), Debye-Scherrer diffraction patterns from the oxidizing specimen were reco...

The potential benefits of transgenic rootworm corn (Cry3Bb1 protein) are expected to include: increased root protection; increased intangible benefits to farmers (safety of not being exposed to insecticides, ease of use and handling, time and labor savings, better pest control); increased economic benefits to farmers ($231 million from yield gains [$25-$75/acre relative to no insecticide contro...

2023 is a momentous year for the Quarterly Journal of Royal Meteorological Society (QJ), celebrating its 150th anniversary. The QJ was initiated in 1873 at time when meteorological science growing rapidly scope and importance one first atmospheric journals to be established. had not yet been recognised with use "Royal" title (that bestowed by Queen Victoria 1883). International Organization als...

The fidelity of new reanalysis datasets (MERRA, 20CR, CFSR, ERA-Interim) at representing climate variability of the 20th century has enabled significant advances in climate research. In this research proposal, we will investigate known shortcomings of these datasets, while developing a framework for a new NOAA Climate Reanalysis (NCR) system to ameliorate them. The NCR will eventually have four...
