Although software is the key enabler of the global information infrastructure, the amount and extent of software in use in the world today are not widely understood, nor are the programming languages and paradigms that have been used to create the software. The vast size of the embedded base of existing software and the increasing costs of software maintenance, poor security, and limited functionality are posing significant challenges for the software R&D community. 相似文献

A total of 1 399 samples of wild animals, cats, mice, rats and fur animals were examined for Trichinella larvae during the period 1.1.1982-30.6.1984. Samples were obtained both from the problem area, were Trichinella larvae had been found in pigs, and for comparison from the rest of Finland. The frequency of the infection in wild carnivores, badgers, pine martens, raccoon dogs, foxes and wild mink was significantly higher in the problem area than in the rest of Finland. 相似文献

This study compared the sensitivity of acetate tape impression and skin squeezing with that of deep skin scraping for the diagnosis of demodicosis in dogs. Demodex canis was detected in 100% of acetate tape impressions obtained after skin squeezing and in 90% of deep skin scrapings. There was a significant difference (P < 0.001) between the techniques in the total number of mites detected. Acetate tape impression with skin squeezing was found to be more sensitive than deep skin scraping and is an alternative diagnostic method for canine demodicosis. 相似文献

Serotests were conducted on axis (Axis axis) and fallow (Dama dama) deer at Point Reyes National Seashore to determine their status with respect to nine diseases enzootic to the native black-tailed deer (Odocoileus hemionus columbianus) or to resident dairy cattle. In the exotic deer, the proportion of animals that were seropositive included: anaplasmosis, 35%; bluetongue, 48%; brucellosis, 0%; bovine viral diarrhea, 2%; infectious bovine rhinotracheitis, 3%; leptospirosis, 7%; parainfluenza-3, 49%; toxoplasmosis, 8%; and Q fever, 51%. The prevalence of antibodies among a small sample of the black-tailed deer included anaplasmosis, 100%; toxoplasmosis, 29%; and Q fever, 57%. The antibody prevalences in a sample of dairy cattle in the area included anaplasmosis, 19%; toxoplasmosis, 8%; and Q fever, 100%. 相似文献
