Experimental and Toxicologic Pathology | Year: 2010

Recent international summits of the International Federation of Societies of Toxicologic Pathologists (IFSTP) have debated the desirability and potential means by which the proficiency of an individual toxicologic pathologist might be recognized and communicated throughout the world. The present document describes the advantages and disadvantages of implementing such a global recognition system by any means, and provides a proposal whereby recognition might be accorded via rigorous credential review of a practitioner's education and experience. © 2009 Elsevier GmbH.

In-seam seismic (ISS) refers to methods which utilise artificially generated channel waves trapped in coal seam to locate geologic disturbances and mine voids. It is one of the basic geophysical methods for underground survey. The advantage of ISS is that seismic energy is better preserved in coal seams and seismic waves can travel and be detected over much larger distances in comparison with body waves which radiate three-dimensionally. It is also convenient and reasonable to set up a two-dimensional model to study the wave propagation characteristics. Using a commercial finite element method (FEM) modelling software, both transmission and reflection tests were simulated. Field experiments of the ISS technology have been carried out at underground coal mines. The results demonstrated that two-dimensional FEM modelling appears to be a satisfactory approach for ISS simulation, and if used properly, ISS technology can successfully detect mine voids and geologic discontinuities. © 2014 Inderscience Enterprises Ltd.

Hydrazones are important classes of compounds found in many synthetic products. Due to their importance in synthetic chemistry, the present article reports the synthesis of twelve new hydrazone derivatives based on the coupling of 2,5-difluorobenzohydrazide with different benzaldehydes and screened for their antibacterial activities at the concentration 250 μg/mL with reference to the standard antibacterial drug Ampicillin. The screening results revealed that hydrazone derivatives 4d, 4e, 4f and 4h having fluorine substitution showed significant antibacterial activity comparable to that of standard drug Ampicillin. © 2013 Bentham Science Publishers.

The purview of a behavioral economist can help utilities plan how to adjust and communicate rate changes in a way that caters to public sense over public sensibility. Most people gauge savings in the context of its relation to total cost. Mental accounting is relevant to utilities in their dealings with price fluctuations. In theory, a commodity increase should have the same emotional intensity as a price decrease of an equal dollar amount. Professor Daniel Putler, a former researcher at the US Department of Agriculture, studied this very theory. Over the course of a year, he tracked the relationship between price fluctuations and purchase amounts. The same is true for expecting people to understand that deferring needed incremental rate increases will almost inevitably provoke outrage down the line when the utility must play catch-up with those rates.

Wood Thrushes (Hylocichla mustelina) are experiencing widespread population declines. Knowing the relative contribution of predator species to overall rates of nest predation of Wood Thrushes, and understanding how the thrushes are affected by temporal and landscape factors, may be important elements in choosing and devising effective management strategies. We used miniature video cameras to identify nest predators of Wood Thrushes in a highly fragmented landscape in Ontario. Eleven species of birds and mammals were recorded as nest predators. Birds accounted for almost twice as many predation events as mammals, and three species-Brown-headed Cowbird (Molothrus ater), Cooper's Hawk (Accipiter cooperii), and raccoon (Procyon lotor)-accounted for the majority. Species such as American Crow (Corvus brachyrynchos), Blue Jay (Cyanocitta cristata), eastern gray squirrel (Sciurus carolinensis), and Common Grackle (Quiscalus quiscula) that are often speculated to be important nest predators in agricultural and suburban landscapes contributed little or nothing to overall predation rates. We tested hypotheses concerning effects of nest stage, time of nesting season, forest size, forest cover, urban housing pressure, and prior predation events at a nest on the probability of nest predation. Our models showed only two of these factors to be significant: prior predation at a nest increased the chance of a subsequent predation event and increasing the measure of urban pressure reduced the chance of a predation event. The many alternate and easy food sources associated with humans might divert the attention of potential predators from nesting birds in urban forests. © 2013 by the Wilson Ornithological Society.
