Despite many advances in recent years, crystal engineering remains a risky venture. A successful outcome requires manipulation of the noncovalent bonding and properties such as size, shape, repulsion, attraction, polarity, and chirality. In this Account, we describe the interplay of… Read moreHelical Tubuland Diols: A Synthetic and Crystal Engineering Quest
The objective of this research was to estimate differences in heat; mass transfer between freeze dryers due to inherent design characteristics using data obtained from sublimation tests. This study also aimed to provide guidelines for convenient scale-up of the freeze-drying… Read moreHeat; mass transfer scale-up issues during freeze-drying, III: Control; characterization of dryer differences via operational qualification tests
The high-temperature strength and deformation behavior of ?/?? two-phase Co–Al–W-base alloys have been studied with polycrystalline and single-crystal materials. The ternary, quaternary and higher-order alloys containing Ta, Cr and/or Re exhibit flow stress anomalies above 873 K due to slip… Read moreHigh-temperature strength and deformation of ?/?? two-phase Co–Al–W-base alloys
A special mechanism of dislocation nucleation in deformed nanocrystalline metals and ceramics is theoretically described. The mechanism represents non-local homogeneous nucleation of a nanoscale loop of “non-crystallographic” partial dislocation whose Burgers vector magnitude continuously grows during the nucleation process. The… Read moreHomogeneous nucleation of dislocation loops in nanocrystalline metals and ceramics
This study examined the relative effectiveness of three structural approaches to reducing team size. Seventy-one five-person teams engaged in a simulated interactive task in which the approach to downsizing was manipulated. Results suggest that the structural approaches to reducing team… Read moreHOW DIFFERENT TEAM DOWNSIZING APPROACHES INFLUENCE TEAM-LEVEL ADAPTATION AND PERFORMANCE.
Research on multinational corporations (MNCs) and host government political risk in developing countries has largely ignored local electoral politics, economic policies, and the MNC investment incentives they may generate. In response, I develop and test a framework for understanding MNC… Read moreHOW DO MNCS VOTE IN DEVELOPING COUNTRY ELECTIONS?
The HIV/AIDS pandemic in Africa has far-reaching implications for governance and development. In addition to killing millions of individuals and causing serious economic contractions, the pandemic threatens structural transformations in African economies, institutions and governance.
BACKGROUND: Pulmonary aspiration of vegetable matter may be a serious cause of lung damage, requiring, almost always, the help of a histopathologic examination. CASE: We report the case of a 55-year-old woman with a granulomatous pneumonitis due to repeated pulmonary… Read moreHistologic findings and comparison with sputum smears in pulmonary aspiration of vegetable particles in syringomyelia:a case report
