The specific capsular polysaccharide of type 46 Streptococcus pneumoniae (American type 73) was isolated in pure form and shown to be a high-molecular-weight, glycosidically linked polymer composed of d-galactose (2 mol), N-acetyl-d-glucosamine (1 mol), N-acetyl-d-galactosamine (1 mol), and N-acetyl-l-fucosamine (1 mol).

73 WHILE REVIEWING VARIOUS high-crash-location (HCL) analysis guides, the authors identified some common misconceptions and areas needing further elaboration. In the companion feature “Improving the Identification, Analysis and Correction of High-Crash Locations,” the authors provide an overview of the HCL process and describe five important concepts for understanding and analyzing HCLs.1 These...

Google Earth (GE) provides very high resolution (VHR) natural-colored (red-green-blue, RGB) images based on commercial spaceborne sensors over worldwide coastal areas. GE is rarely used as a direct data source to address coastal issues despite the tremendous potential of data transferability. This paper describes an inexpensive and easy-to-implement methodology to construct a GE natural-colored...

URh 2 Ge 2 occupies an extraordinary position among the heavy–electron 122– compounds, by exhibiting a previously unidentified form of magnetic correlations at low temperatures, instead of the usual antiferromagnetism. Here we present new results of ac and dc susceptibilities, specific heat and neutron diffraction on single–crystalline as–grown URh 2 Ge 2. These data clearly indicate that cryst...
