Received ; accepted – 2 – ABSTRACT Historically the narrow line radio galaxies were thought to be intrinsically nonthermal, and without significant accretion. When the Unified Model came along the compelling observational motivation for this lost some force: some are found to be hidden broad line objects, and in principle that could be the case with all of them. The clear sign of a hidden quasa...

Predatory potential and performance of the predaceous heteropterans, Geocoris punctipes (Say), G. uliginosus (Say) (Geocoridae), and Orius insidiosus (Say) (Anthocoridae), were evaluated using fall armyworm, Spodoptera frugiperda (J. E. Smith), as prey on different turfgrass taxa (resistant zoysiagrasses, 'Cavalier' and 'Palisades'; moderately resistant Bermuda grass, 'TifSport'; and susceptibl...

The Brill{Hartle gravitational geon construct as a spherical shell of small amplitude, high frequency gravitational waves is reviewed and critically analyzed. The Regge{Wheeler formalism is used to represent gravitational wave perturbations of the spherical background as a superposition of tensor spherical harmonics and an attempt is made to build a non{singular solution to meet the requirement...

Warren was a philosopher and scientist. As a freshman at Haverford College he told the Quaker philosopher Rufus Jones that all he wanted to know was: "What is a number that a man may know it; and a man, that he may know a number?" To this the Quaker famously replied: "Friend, thee will be busy as long as thee lives." Warren acknowledged in his last days that the prophecy had been fulfilled, and...

Philosopher: Today, I suggest we discuss the important concepts of common knowledge and common belief. As far as I know, the first one to give a formal analysis of these concepts was the philosopher David Lewis, in his book Convention [131]. One of his examples is traffic conventions, about the role of common knowledge in how one behaves in road traffic. To explain this properly, I wonder if yo...
