Complex patterns in a simple system     

Pearson JE 《Science (New York, N.Y.)》1993,261(5118):189-192

Numerical simulations of a simple reaction-diffusion model reveal a surprising variety of irregular spatiotemporal patterns. These patterns arise in response to finite-amplitude perturbations. Some of them resemble the steady irregular patterns recently observed in thin gel reactor experiments. Others consist of spots that grow until they reach a critical size, at which time they divide in two. If in some region the spots become overcrowded, all of the spots in that region decay into the uniform background.  相似文献

Inflammatory middle ear disease of the dog: the clinical and pathological features of cholesteatoma, a complication of otitis media     

C J Little  J G Lane  C Gibbs  G R Pearson 《The Veterinary record》1991,128(14):319-322

During a study of inflammatory middle ear disease in the dog cholesteatoma was found to accompany otitis media in seven of the 62 ears examined (11 per cent). The clinical, radiological and pathological findings in these animals imply that cholesteatoma in the dog is an aggressive lesion which must be differentiated from uncomplicated otitis media.  相似文献

Response to selection for milk yield and metabolic challenges in primiparous dairy cows     

A. J. Lukes  M. A. Barnes  R. E. Pearson 《Domestic animal endocrinology》1989,6(4):287-298

The effect of selection for milk yield on lactation yield, net energy balance, and on plasma growth hormone, insulin, prolactin, nonesterified fatty acids and glucose was studied in two groups of primiparous Holstein cows of differing genetic merit. Net energy balance was calculated and serial blood samples were collected for a 7 hr period at 0, 45, 90 and 180 days postpartum. Growth hormone releasing factor (.2 μg/kg BW) was administered after 2.5 hr at 0, 45 and 180 days postpartum, while epinephrine (.7 μg/kg BW) was administered at 90 days postpartum, Milk yield was greater, net energy balance was decreased and plasma growth hormone was greater in genetically superior selection group cows compared to control cows.

Growth hormone showed similar increases in both genetic groups in response to growth hormone releasing factor, while prolactin, insulin and glucose were not altered. Epinephrine stimulated an increase in plasma nonesterified fatty acid, glucose and insulin, but responses did not differ between genetic groups. Results indicate differences exist in production efficiency, net energy balance and plasma growth hormone concentration among dairy cattle as a result of selection for milk yield and suggest that selection pressure may act to alter homeorhetic control of nutrient metabolism.  相似文献   

Survey for antibodies to viruses of bovine virus diarrhea, bluetongue, and epizootic hemorrhagic disease in hunter-killed mule deer in New Mexico     

C E Couvillion  E W Jenney  J E Pearson  M E Coker 《Journal of the American Veterinary Medical Association》1980,177(9):790-791

Sera from male mule deer (Odocoileus hemionus) collected in November 1977 in Otero County, New Mexico were tested fro antibodies to bovine virus diarrhea virus (BVDV), bluetongue virus (BTV), and epizootic hemorrhagic disease virus (EHDV). Neutralizing antibodies were detected in 26 of 76 (34%) sera tested for BVDV (titer greater than or equal to 1:16). Of 46 sera tested for antibodies to BTV and EHDV, 10 (22%) and 3 (7%), respectively, were positive. Three (7%) of 46 sera were suspect (titer < 1:20) for BTV, and 18 (38%) sera were suspect (titer < 1:20) for EHDV.  相似文献   

Failure to demonstrate viscerotropic velogenic Newcastle disease in psittacine birds in the Republic of the Philippines     

D C Johnson  C E Couvillion  J E Pearson 《Avian diseases》1986,30(4):813-815

Birds on the islands of Luzon, Mindanao, and Palawan in the Republic of the Philippines were surveyed for viscerotropic velogenic Newcastle disease (VVND). Virus isolation was attempted on 728 cloacal samples from native and exotic psittacine birds, non-psittacine birds, and domestic chickens and ducks. A VVND virus isolate was obtained from a single domestic chicken that had exhibited ocular discharge and diarrhea 3 days before sampling. All other birds were negative for VVND.  相似文献
