A brief return to the high school classroom in 2004 provided me with the opportunity to teach young adult literature for the first time in my career. In the six years I taught English and reading, from 1996 to 2002, I only used classic works—Great Expectations, A Separate Peace, Romeo and Juliet, etc. It wasn’t that I didn’t like or want to teach young adult fiction; my schools never provided s...

People are often able to act eeciently in places like grocery stores, libraries, and other man-made domains even if they haven't been to those particular places before: They are exercising useful knowledge about how these environments are organized in order to facilitate their tasks. In this paper we show that everyday environments exhibit useful regularities an autonomous agent can use in orde...

We study elasticity-driven morphological transitions of soft spherical core-shell structures in which the core can be treated as an isotropic elastic continuum and the surface or shell as a tensionless liquid layer, whose elastic response is dominated by bending. To generate the transitions, we consider the case where the surface area of the liquid layer is increased for a fixed amount of inter...

Sir,?Much evidence purporting to support the theory that sandflies transmit leishmaniasis has accumulated. This is not surprising for such evidence has been looked for too assiduously and Pasteur's dictum?? Be very careful when you are looking for a thing or you will be sure to find it'?has been frequently ignored in these investigations. Malone and Brooks (1944) gave reasons for believing that...

Herein, twoN-substituted coumaryl hydroxylamines (compounds 1a and 1b) with long aliphatic chains were prepared in 8 steps with a novel synthetic protocol. They served as derivatization agents for aldehydes by the formation of nitrones under mild conditions, which can be readily analysed by LC-MS with good chromatographic performance, excellent fluorescent response, and high ionization strength...

in this work, thermal degradation behavior of a fuel-rich energetic mixture containing epoxy binder was studied by thrmogravimetric analysis and differential scanning calorimetry under dynamic nitrogen atmosphere at different heating rates. variation of the thermal degradation activation energy of the mixture was evaluated by differential and integral isoconversional methods via akts software p...
