but neither should be implicated in the views expressed here. I would also like to thank Chris Allsopp, Ron Smith and David Vines for useful comments at the conference.

Four novel diimine rhenium(I) carbonyl complexes with the formula [Re(CO)3(L)Br], where L = 2-(4-(9H-carbazol-9-yl)phenyl)-1H-imidazo[4,5-f][1,10]phenanthroline (P1), 2-(4-(3,6-di-tert-butyl-9H-carbazol-9-yl)phenyl)-1H-imidazo-[4,5-f][1,10]phenanthroline (P2), 2-(4-(6-(9H-carbazol-9-yl)-9H-3,9-bicarbazol-9-yl)phenyl)-1H-imidazo[4,5-f][1,10]phenanthroline (D1), and 2-(4-(3',6'-di-tert-butyl-6-(3...

In this study, measured hydrophysical data collected by the University of Miami researchers from the southern part of the Strait of Hormuz during the period December 1996 to March 1998 and climate data from the Qeshm island meteorological station were used to simulate water column turbulence south of the Qeshm Island, via General Ocean Turbulence Model (GOTM). The model does not use slip and fl...

We describe an algorithm for slicing an unstructured triangular mesh model by a series of parallel planes. We prove that the algorithm is asymptotically optimal: its time complexity is O(n log k+k+m) for irregularly spaced slicing planes, where n is the number of triangles, k is the number of slicing planes, andm is the number of triangle-plane intersections segments. The time complexity reduce...

Aims. We observed two compact high-velocity clouds HVC 291+26+195 and HVC 297+09+253 to analyse their structure, dynamics, and physical parameters. In both cases there is evidence for an association with the Leading Arm of the Magellanic Clouds. The goal of our study is to learn more about the origin of the two CHVCs and to use them as probes for the structure and evolution of the Leading Arm. ...

We present the results of ROSAT and XMM-Newton observations of the recurrent ultraluminous X-ray source (ULX) NGC 253 ULX1. This transient is one of the few ULXs that was detected during several outbursts. The luminosity reached 1.4×1039 erg s−1 and 0.5×1039 erg s−1 in the detections by ROSAT and XMM-Newton, respectively, indicating a black hole X-ray binary (BHXRB) with a mass of the compact o...

Yields on 'Concord' grape (Vitis labrusca L.) increased as pruning severity was decreased until the 6th and last year of this study, at which time the yields tended to equalize between the 30 + 10, 50 + 10, and 70 + 10 pruning treatments. By the last year, vines pruned to the 70 + 10 level produced fruit of unacceptable quality. When the 3-node spurs were shoot-positioned, their productivity wa...

In this article we present a model of insect infestation of grape vines and consider the optimal control of the pest through the use of egg pesticides. We show existence and uniqueness and present the results of some numerical simulations.

Alternaria leaf blight is a much greater threat to muskmelons than watermelons. The disease is caused by a fungus (Alternaria cucumerina) that can rapidly defoliate plants, causing reductions in bulk yield. Melons on defoliated vines ripen prematurely and result in lower quality fruit compared to melons produced on healthy vines. Yield losses greater than 50% will occur in situations where the ...

Rapid growth in networks and related services have resulted in demands for more e ective, accessible, intelligent and scalable network management systems. Not only managers but also users need access to network management information. Traditional network management architectures are utterly inadequate to meet these requirements. In this work we describe VINES a next generation network managemen...
