The Kramer–Neugebauer–like transformation is constructed for the stationary axisymmetric D=4 Einstein–Maxwell–dilaton–axion system. This transformation directly maps the dualized sigma–model equations of the theory into the nondualized ones. Also the new chiral 4× 4 matrix representation of the problem is presented.

Using the Kramer-Mesner method, 4-(26, 6, λ) designs with PSL(2, 25) as a group of automorphisms and with λ in the set {30, 51, 60, 81, 90, 111} are constructed. The search uses specific partitioning of columns of the orbit incidence matrix, related to so-called “quasi-designs”. Actions of groups PSL(2, 25), PGL(2, 25) and twisted PGL(2, 25) are being compared. It is shown that there exist 4-(2...

VOLUME 89, NO. 3 Infant mortality is a frequently used measure of population health status. Because of concern that Canada’s infant mortality rate (IMR) was rising, Joseph and Kramer examined trends in Canada’s IMR and the effect of registering extremely low birthweight (under 500 grams) infants as live births. A live birth is defined as any infant who, after delivery, “...breathes or shows any...

Water deficit is the major abiotic factor limiting plant growth and crop productivity around the world (Kramer, 1983). Approximately one third of the cultivated area of the world suffers from chronically inadequate supplies of water (Massacci et al., 2008). In all agricultural regions, yields of rain-fed crops are periodically reduced by drought (Kramer, 1983), and the severity of the problem m...

First I emphasize the magnetospheric loop current system induced by the wind activity. Next, I address the formation of the fieldaligned electric field. An interesting aspect is the reaction of the inner magnetosphere to an induced current. In the traditional outer gap, the current running through the gap is all carried by the particles created in the gap. However, if external current-carrying ...
