  • Volume 41 of the Handbook on the Physics and Chemistry of Rare Earths adds four chapters to the series: two focus on nanoscale rare-earth mate- rials, while the other two are concerned with divergent topics—the arrangement of the rare-earth elements in the periodic table, and the higher order rare-earth chalogenide compounds with the elements of the 14th group and also In. The first chapter (248) discusses the various proposals suggested for the location of the rare-earth elements in the periodic table from the time of Mendeleev to the present day.

  • The algorithms for all the relational operators are written as if they were to be run on a single processor. As shown in Figure 3, the input to an Operator Process is a stream of tuples and the output is a stream of tuples that is demultiplexed through a structure we term a split table. Once the process begins execution, it continuously reads tuples from its input stream, operates on each tuple, and uses a split table to route the resulting tuple to the process indicated in the split table. 4 When the process detects the end of its input stream, it first closes the output...

  • Inorganic chemistry is concerned with the chemical elements (of which there are about 100) and the extremely varied compounds they form. The essentially descriptive subject matter is unified by some general concepts of structure, bonding and reactivity, and most especially by the periodic table and its underlying basis in atomic structure.

  • When you buy an existing business, you are assuming responsibility for an existing customer base. You are most concerned with the ability of the business to continue earning profits. The price you choose to pay for this business, therefore, is more related to the business' past profit earning record. One commonly accepted way of evaluating the business is projecting its profits for the next three years based on its last three years and discounting the present value (using present value tables) to this year.
