In this study a trial was performed to determine the effect of a combination of two aqueous extracts of two medicinal plants namely the violet, Viola odorata, and the rue, Ruta graveolens, with concentrations of 0.15625, 0.3125, 10-20 mg/cm3 on the growth of Trichomonas vaginalis cultured in (CM161) medium during periods of 24, 48, 72, and 96 hrs. The results showed that there is a variation of...

Over evolutionary time, the morphology of angiosperm pollen has evolved toward an increasing number of apertures, among other things. From a neo-Darwinian point of view, this means that (i) some polymorphism for aperture number must exist and (ii) there must be some fitness increase associated with increasing the aperture number. Pollen types with different aperture numbers often occur in the s...

A greater knowledge of the morphology and the development of the infective third larval stage of Neoaplectana bibionis Bovien, 1937, a parasite of arthropods, makes it possible to recognise the second larval stage and present a description of all the developmental stages in the life cycle of the species. Four larval stages can be recognised. L1 hatches from the egg. In a suitable host, when the...

Five species of Oxyporinae: Oxyporus occipitalis Fauvel, Oxyporus quinquemaculatus LeConte, Oxyporus major Gravenhorst, Oxyporus rufipennis LeConte, and Oxyporus stygicus Say, are newly recorded from New Brunswick, bringing the number of Oxyporinae known from the province to eight. The first documented records from New Brunswick are provided for Oxyporus kiteleyi reported by Majka et al. (2011)...

”Extension du corps sonore” is long-term project initiated by Musiques Nouvelles [4], a contemporary music ensemble in Mons. It aims at giving instrumental music performers an extended control over the sound of their instrument by extending the understanding of the sound body from the instrument only to the combination of the instrument and the whole body of the performer. The development start...

In this paper a neural adaptive control method has been developed and applied to robot control. Simulation results are presented to verify the effectiveness of the controller. These results show that the performance by using this controller is better than those which just use either direct inverse control or predictive control. In addition, they show that the resulting is a useful method which ...

This paper presents a new growing neural network for cluster analysis and market segmentation, which optimizes the size and structure of clusters by iteratively checking them for multivariate normality. We combine the recently published SGNN approach [8] with the basic principle underlying the Gaussian-means algorithm [13] and the Mardia test for multivariate normality [18, 19]. The new approac...

The growth of open networks created the interest to commercialise it. The establishment of an electronic business mechanism must be accompanied by a digital – electronic payment system to transfer the value of transactions. Financial organizations are requested to offer a secure e-payment synthesis with equivalent level of security served in conventional paper-based payment transactions. PKI, w...
