IN THE NEWS FOCUS STORY “WEATHER forecasts slowly clearing up” (9 November, p. 734), R. Kerr nicely summarizes how the growing improvement in prediction is coming from a focus on “more computer power, the assimilation of radar observations, and more physically realistic models.” He emphasizes that better assimilation of satellite data is a key element of improved forecasting. Unfortunately, the...

T-14326A Abstract A decade ago, Capillary Electrophoresis (CE) was considered a novelty. Today it is commonly used in quality control worldwide, providing automated, high-resolution methods, with online detection. In the first part of this series of articles, we will illustrate an overview of CE in a modern quality control laboratory. The complete series of articles will address in depth the fo...

Interprocedural analyses can be classiied as either context-insensitive, which tend to sacri-ce precision to gain eeciency, or context-sensitive, which are more precise but also more expensive. This paper discusses a proole-guided approach to interprocedural analysis that is context-sensitive, and hence more precise, for the \important" call sites for a function, and context-insensitive, and he...

A novel approach based on ionic liquid-single-drop microextraction (IL-SDME) online coupling with capillary electrophoresis (CE) was used to determine a toxic alkaloid--colchicine. The IL-SDME procedure was optimized by extraction solvent, drop volume controlling, sample volume and pH, extraction time, and ionic strength. Under optimum conditions, enrichment factor was as much as 41-fold with a...

Manganese oxide-loaded and -doped ceria as well as the corresponding barium-modified oxide catalysts were prepared for soot oxidation in the presence of NO(x), and were characterized by using X-ray diffraction, Brunauer-Emmett-Teller and NO temperature-programmed oxidation measurements. The activity of catalyst depended strongly on the NO2 production capacity, and the importance of surface nitr...

English sentences such as: (1) John appreciates that book. (2) John appreciates this book. can both be translated into French as: (3) Jean apprécie ce livre. (‘Jean appreciates ce book’) so that ce seems neutral between that and this. To express the English distinction, French adds -là or ci: (4) Jean apprécie ce livre-là. (‘Jean appreciates ce book-there’) (5) Jean apprécie ce livre-ci. (‘Jean...
