The Leg 104 organic geochemistry program consisted of monitoring (a) hydrocarbon gases, (b) organic and inorganic carbon, and (c) parameters resulting from Rock-Eval pyrolysis at three sites on the Vdring Plateau. The results amplify some of those obtained earlier on Deep Sea Drilling Project (DSDP) Leg 38. In a regional sense there is an inverse correlation between amounts of hydrocarbon gas a...

Wire and gate delays are accounted to have equal, or nearly equal, effect on circuit behavior in modern design techniques. This paper introduces a new approach to verify circuits whose behavior is independent of component delays (delay-insensitive). It shows that for a particular way of implementing a delay-insensitive circuit, through a Null Convention Logic methodology, the complexity of the ...

Abstract This presentation will discuss the results of an archaeological field trial using a wearable (PC/104) image capture system in order to demonstrate the potential of image sequence tagging methods for efficient data retrieval in docu...

We derive helicity amplitudes for diffractive leptoproduction of the S and D wave states of vector mesons. We predict a dramatically different spin dependence for production of the S and D wave vector mesons. We find very small R = σL/σT and abnormally large higher twist effects in production of longitudinally polarized D-wave vector mesons. Diffractive vector meson production γ∗ + p→ V + p′, i...

BACKGROUND NXL104 is a novel-structure beta-lactamase inhibitor with potent activity against both class A and class C enzymes. Among the class A carbapenemases, KPC-type enzymes are now spreading rapidly and KPC-related carbapenemase resistance is an emerging phenomenon of great clinical importance. The activity of NXL104 against KPC beta-lactamases was examined. METHODS Enzymatic activity of...

In the title compound, C(19)H(13)N(5)·C(4)H(8)O(2)·2H(2)O, the mol-ecular skeleton of the 2,6-bis-(benzimidazol-2-yl)pyridine (bbip) mol-ecule is essentially planar (r.m.s. deviation = 0.023 Å). An extensive three-dimensional network of inter-molecular N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds consolidates the crystal packing, which also exhibits π-π inter-actions between the five- and six-membered...
