copper as a material for electric cables. A previous survey of respiratory complaints after the use of this particular flux had failed to show any objective change in lung function, and the present cases are the first to be reported. Both subjects have been investigated by means of serial spirometry, peak flow rates, and body plethysmography following inhalation of small amounts of flux fumes; ...

Legislation is being developed worldwide to reduce the lead content in many consumer electronic products. This is being taken as an action to reduce environmental impact when such products are discarded. Despite the fact that lead containing solders in electronic assemblies account for only 0.49% of world lead consumption, the trend in legislation will likely be to require not only reduced lead...

An interesting tool for investigating the quantum features of a field theory is the introduction of compensating fields. For instance, the anomalous divergence of the chiral current can be calculated in the field-antifield formalism from an extended form of QCD with compensating fields. ons, how is the mapping between bosonic and fermionic representations of this extended QCD2. In the bosonic f...

The idea of a book being a collection of pages is so ingrained that modern electronic book readers often try to faithfully reproduce this feature — up to elaborate simulations of page turns. However, traditional pages are not necessary and often inconvenient in electronic books. It is often easier to scroll the text than to turn the pages, and text reflowing makes the use of folios a rather str...
