Multiwaveband images of extended jets in quasars reveal that in some locations electrons reach energies of at least 100 TeV, while in others the particle acceleration is less efficient. The jet of the quasar 1317+520 (z=1.06) contains shocks that are both transverse and oblique to the jet axis as well as regions where the axial magnetic field and polarization indicate cross-jet velocity shear. ...

Air Force (under the RASSP program, contract F33615-93-C-1317), Semiconductor Research Corporation (project 94-DC-008), National Science Foundation (MIP-9201605), Office of Naval Technology (via Naval Research Laboratories), the State of California ...

Parents play a central role in their children’s emotional and overall development. To provide the most developmentally sound environment, professionals need to communicate the fine points of research and clinical studies effectively. This article details many strategies for reaching parents; perhaps the most important lessons are to be culturally sensitive, be positive, be relevant, and speak c...

The Robust Project aims to improve scientific and technical knowledge on the main issues still open in the new European standards on road restraint system EN 1317 [1-2]. The knowledge acquired will form the basis of updated standards for EN1317 and lead to more advanced road restraint systems and improve road-users safety. This report is part of the deliverables from Work Package 5 (WP5)-Comput...

The article provides the most complete review of surviving manuscripts «Book Union» by Mar Babai Great, concludes that all later copies depend on one protograph, and clarifies its dating. A brief history discovery lost fragments is also given, their critical text based two (Cambridge Or. 1317 British Library 9379) translation into Russian are published.
