Non-vacuum exact gravitational waves invariant for a non Abelian two-dimensional Lie algebra generated by two Killing fields whose commutator is of light type, are described. The polarization of these waves, already known from previous works, is related to their natural sources consisting of cosmic strings and γ-ray bursts. Non vacuum exact gravitational waves admitting only one Killing field o...

EA TI VE S O LU TI O N S When Congress established the State Children’s Health Insurance Program (SCHIP) in 1997, it also enacted presumptive eligibility, a new state option for expediting children’s enrollment in Medicaid.1 Presumptive eligibility helps states cover children more quickly by allowing them to provide immediate, but temporary, enrollment in Medicaid or SCHIP to children who appea...

The AMMTIAC Quarterly, Volume 1, Number 2 3 INTRODUCTION Detecting and locating insulation defects in wiring systems is a nontrivial challenge. Ideally, the diagnostic should be nondestructive, capable of detecting a variety of insulation defects, such as cracking, chaffing, and abrasion, and be able to locate the defect accurately to reduce potential inspection and maintenance costs. The diagn...

Several questions of scientometrics parameters organization are considered. Two new indices for scientific works citation analysis are proposed. They provide more detailed and reliable scientific significance assessment of individual authors and scientific groups basing on the publication activity. (точнее их разработчиков
