ABSTRACT: A tropical cyclone is a warm core intense low pressure system around which air circulates in anti-clockwise direction in northern hemisphere and in clockwise direction in the southern hemisphere. Tropical Cyclones (TCs)are one of the most devastating hazardous weather events in the world. In the present study, Genesis Potential Parameter (GPP) has been used to predict the tropical cyclogenesis using the Numerical Weather Prediction (NWP) model analysis as well as forecasts (up to 96-h). The National Centers for Environmental Prediction (NCEP) Global Forecast System (GFS) high resolution (0.25º ×0.25º) data is used to detect the genesis and its location of tropical.......

Keywords: Cyclogenesis, GFS, GPP, FAR and POD.

ABSTRACT: Résumé : Contexte : L'irradiation solaire perçue à la surface de la terre est une énergie indispensable pour couvrir les insuffisances liées à la fourniture en énergie électrique et aux dangers que nous guettent les énergies polluantes. Cependant, la maîtrise de l'irradiation solaire globale perçue est conditionnée par des mesures in situ qui nécessitent la présence d'outils appropriés (pyranomètres, pyrhéliomètre, spectro-radiomètre, …). Malheureusement, la rareté de ces outils de mesure n'offre pas d'opportunité à leur accessibilité. Voilà pourquoi, il convient de déterminer les modèles mathématiques adaptés à la position géographique du lieu, pour évaluer l'irradiation solaire et de dégager......

ABSTRACT: It is proposed that graviton is composed of Wu's Pairs, a Yangton and Yington circulating particle pairs with build-in attractive Force of Creation (Building Blocks of the universe). Gravitational force is generated by string force between two gravitons and the propagation of gravitational force is explained by graviton radiation and contact interaction. In addition, the dimension and duration of an object or event can change with the local gravitational field due to the bombardment of gravitons and aging of the universe in compliance with CMB radiation. Because of the same intrinsic structures, the amount of unit quantity in a corresponding identical objects or events......

ABSTRACT: Since a number of physical properties and mechanical behaviour is dependent on bulk density; the need for greater precision in its determination is key for good soil management and productivity. This study assessed the effect of 4 core sizes (5cmx5cm, 5cmx10cm, 10cmx5cm and 10cmx10cm), moisture content at different seasons (dry season- MC1, early rains- MC2 and peak rains MC3) and 3depths (0-10, 10-20 and 20-30cm) on bulk density values. The results show that core size dimension and not volume affected bulk density values. The 5cmx5cm (C1) and the 10cmx10cm (C4) gave similar values, while the 5cmx10cm gave values that were quite significantly higher than the other sizes (P<0.05). Bulk density values, generally increased with depth, except for samples taken at the high moisture.....

ABSTRACT: The cosmos is a puzzle that all learning is trying to unravel. It has neither a user manual nor an easily apparent order that would have served as its ultimate un-riddling. Man is fated to confront the comprehension of the cosmos with bare intellect in order to eke out meaning from the enormously disordered order that is the cosmos. The critical issue to be determined is the extent of the cosmos. The extent of the cosmos might not be determined without determining the nature of the cosmos. If the properties that make up the cosmos could be measured, the extent of the cosmos perhaps could be measured as well. But there is a linguistic twist to comprehending the extent of the cosmos. If the cosmos.....

ABSTRACT: Palladium Sulphide thin films were successfully deposited on a glass substrate using the chemical bath deposition method. The effect of varying concentration of aluminum dopant on the PdS thin film was also investigated by varying the concentration of aluminum in the form Alx where x = 0.3 and 0.5. Post deposition annealing was also done on the aluminum doped PdS film at temperatures of 50 oC, 100 oC and 150 oC. The optical properties were investigated using UV- spectrophotometer. The result of the analysis showed that while concentration tends to increase the......
