The Fusarium wilt caused by Fusarium oxyspoum f. sp. cubense (Foc) is a major biotic constraint for banana production. The characteristics of F. oxyspoum f. sp. cubense isolates were investigated using electrophoretic studies of isozyme and whole-cell protein. The morphological characteristics of the isolates were very similar to each other. All the Foc isolates were pathogenic to banana cultiv...

We evaluated the relationship between the size of the peripapillary crescent and the axial length (AL) of the eye as well as the fine structure of the peripapillary crescent in selected eyes. Infrared fundus imaging and spectral domain optical coherence tomography (SDOCT) (Spectralis HRA+OCT, Heidelberg Engineering, Germany) centered at the fovea were performed on 72 healthy adults. On the infr...

Uropathogenic Escherichia coli strain J96 carries multiple determinants for fimbrial adhesins. The regulatory protein PapB of P fimbriae has previously been implicated in potential coregulatory events. The focB gene of the F1C fimbria determinant is highly homologous to papB; the translated sequences share 81% identity. In this study we investigated the role of PapB and FocB in regulation of th...

Swarm Intelligence in the form of Particle Swarm Optimization (PSO) has potential applications in electric drives. The excellent characteristics of PSO may be successfully used to optimize the performance of electric machines and electric drives in many aspects. It is estimated that, electric machines consume more than 50% of the world electric energy generated. Improving efficiency in electric...

Parallel shared memory (PSM) routers represent an architectural approach for addressing the high memory bandwidth requirement dictated by output-queued switches while retaining their desirable performance characteristics. The high speed requirement from the memory management algorithm, which is responsible for placing arriving packets into non-conflicting memories, presents a fundamental challe...

We established an automated screening method to characterize adhesion of Escherichia coli to intestinal porcine epithelial cells (IPEC-J2) and their probiotic activity against infection by enteropathogenic E. coli (EPEC). 104 intestinal E. coli isolates from domestic pigs were tested by PCR for the occurrence of virulence-associated genes, genes coding for resistances to antimicrobial agents an...

A comparison is made between the expected photometric accuracy of the FOC, and that observed. The presently known systematic eeects are listed and quantiied. Typically when both internal and external factors are included one only expects to obtain photometry accurate to 0.2 mag in the ultraviolet. This expectation is tested by comparing magnitudes extracted from F220W images of nine starburst g...

VOUZZAVEDIBISAR Fantaisie Edmond Bianco Quand je tirais le dernier bord, mon petit voilier s'approcha lentement de la côte, je donnais un petit coup de barre pour la longer en cherchant où aborder. Et en même temps je lâchais le foc et la grand'voile. La terre à une dizaine de mètres par trois mètres de fond, une étroite plage de sable, mais aussi pas mal de petits rochers, je ne pouvais aborde...
