Shiba dogs are predisposed to chronic enteropathy (CE) and have poorer prognosis than other dog breeds. The objective of this study was to investigate the significance of polymerase chain reaction for antigen receptor rearrangement (PARR) results on clinical findings and prognosis of Shiba dogs with CE. We retrospectively collected data on 22 Shiba dogs diagnosed as having CE. Fifty-nine percen...
Diluted bitumen (dilbit; the product of oil sands extraction) is transported through freshwater ecosystems critical to Pacific salmon. This is concerning, because crude oil disrupts cardiac development, morphology, and function in embryonic fish, and cardiac impairment in salmon can have major consequences on migratory success and fitness. The sensitivity of early life-stage salmon to dilbit an...
Changes in snow and ice conditions are some of the most distinctive impacts of global warming in cold temperate and Arctic regions, altering the environment during a critical period for survival for most animals. Laboratories studies have suggested that reduced ice cover may reduce the survival of stream dwelling fishes in Northern environments. This, however, has not been empirically investiga...
We present a detailed study of the effects of electron correlation on two-photon absorption calculated by coupled cluster quadratic response theory. The hierarchy of coupled cluster models CCS, CC2, CCSD, and CC3 has been used to investigate the effects of electron correlation on the two-photon absorption cross sections of formaldehyde (CH2O), diacetylene (C4H2), and water (H2O). In particular,...

Some exact conditions for the extremals of the electrophilicity index, ω = μ(2)/2η (Parr, R. G.; von Szentpály, L.; Liu, S. J. Am. Chem. Soc. 1999, 121, 1922), along an arbitrary reaction coordinate, have been carefully examined. Implications within the widely used finite difference approximation for the density-functional based reactivity descriptors, their relationship with the maximum hardne...
on how these systems add value (Markus & Tanis, 1999; Ross & Vitale, 2000; Somers and Nelson, 2001), implementation issues (Parr et al., 1999; Scott & Vessey, 2001), and how they should be combined with other information technology (IT) resources (Hayman, 2000). Being a relatively novel phenomenon, there are aspects of ERP that have not been covered well in research – yet. Two such interrelated...
Materials Two soybean oils, partially hydrogenated (IV 119120) in a 2 liter Parr hydrogenator with laboratoryprepared catalysts containing copper (8) at 30 psi and 170 (sample A) and 200 C (sample B), respectively, were used in this investigation. Samples of each were transesterified in methanol with sodium methoxide catalyst, and the methyl esters were distilled under vacuum. Analvses of these...
