background and objectives: in may 2007, high mortality with severe septicemia was reported in 17 flocks of canaries in different regions of tehran province. this study was designed to follow up and study a great outbreak of salmonellosis in these canaries. materials and methods: two carcasses from every flock, environment, food and water resources were examined. after isolating the bacteria, se...

In many bird species, the sex determination is very difficult in young birds and many adults. Nowadays, sex identification of animals throughout their lives is possible by molecular genetic techniques. In the present study, the sex identification of canaries by PCR methods based on chromo helicase DNA binding protein CHD-Z and CHD-W genes were explained. Genomic DNA was extracted from feather b...

The nematode parasites of 16 large-scaled yellowfish, Barbus marequensis, six silverfish, Barbus mattozi, six small-scaled yellowfish, Barbus polylepis, 52 canary kurper, Chetia flaviventris, 11 carp, Cyprinus carpio, 45 Mozambique bream, Oreochromis mossambicus and a single-banded bream, Tilapia sparrmani, caught in the Hartbeespoort Dam, Transvaal, were collected, identified and counted. Cont...

Relational mechanisms lie at the core of human cognitive organisation, expressed in everyday language by terms such as ‘bigger than’ and ‘smaller than’ and in formal symbolic systems by logical arguments such as A> B. Ordered as a series A>B> C furthermore, such relationally based mechanisms support transitive inferences of the sort that, given A>B and B>C, A must be bigger than C an important ...

Over the last decade vancomycin-resistant enterococci (VRE) have emerged as nosocomial pathogens. The aim of this study was to determine the prevalence of VRE in clinical samples from hospitalized patients in the Canary Islands. From April to November 2000, 437 enterococci were isolated from patients hospitalized at the four main health care centers in those islands. Identification to the speci...

DNA sequences were analyzed from 19 populations of J. phoenicea from throughout its range. The sequence data (nrDNA, petN-psbM) revealed that J. phoenicea is clearly divided into two taxa. These taxa have been recognized as var. (subsp.) phoenicea and var. (subsp.) turbinata by Adams (2011) and Farjon (2005). However, the magnitude of the differences in the DNA regions, along with the differenc...

The domestic camel (dromedary) is the most important livestock species in the Canary Islands and the most important autochthonous European camel population. After six centuries of a successful adaptation process to the particular environment of the Canary Islands, the abandonment of traditional agriculture has led this population to a major bottleneck. Along with a lack of foreign genetic inter...

16 Abstract— This paper presents a technique for compensating process, voltage and temperature variations due to manufacturing and environmental variability in submicron circuits using canary flip-flop. This canary flip flop predicts the timing error before it actually occurs and compensate the performance so that the system performance does not get affected. I am going to design a 16-bit Brent...

Ongoing cti sruption of ancient , varnished desert pave ment surfaces ncar Death Valley Nat ional Park is inferred to be the result of unusually intense animal foraging activity. lncreased levels of biotllrbation are associated with enhanced vegetation growth stimulated by recen t EI Nino precipitation. The occurrence of abundant, recen tly overturned, varnished clasts suggests that the pavemen...
