A perfect matching covering of a graph G is a set of perfect matchings of G such that every edge of G is contained in at least one member of it. Berge conjectured that every bridgeless cubic graph admits a perfect matching covering of order at most 5 (we call such a collection of perfect matchings a Berge covering of G). A cubic graph G is called a Kotzig graph if G has a 3-edge-coloring such t...

We outline our recently started program to investigate the galaxy environment of QSOs, in particular of radio–quiet objects at intermediate redshifts. 1 Studies of QSO environments Galaxy environment studies of QSOs and of their host galaxies are important since tidal interaction with neighbouring galaxies is thought to be one fundamental mechanism for triggering AGN activity (e.g. Osterbrock(1...

Glutamate works as a major excitatory neurotransmitter in the vertebrate retina. Whole-cell recordings made from isolated carp cone horizontal cells (H1 cells) showed that Nmethyl-D-aspartate (NMDA), co-applied with glycine, induced inward currents that were blocked by the NMDA receptor competitive antagonist D -2-amino-5-phosphonopentanoate ( D -AP5) and 5,7-dichlorokynurenic acid (DCKA), a se...

A retrospective chart review analyzed the effect of customized nutrition on the incidence of pregnancy-induced hypertension (PIH), gestational diabetes (GDM), and small- and large-for-gestational-age (SGA, LGA) neonates, examining consecutive deliveries between January 1, 2011, and Decem ber 31, 2012, at a low-risk community hospital. The population was divided into 3 groups: (1) study group (S...
