Nonleptonic Decays of Charmed Mesons into two Pseudoscalar Mesons

We investigate the nonleptonic decay of charmed meson into two pseudoscalar mesons using the vector--dominance model, and compare the results with those obtained from the factorization model. In particular, we discuss the role of the annihilation diagrams in the two models.Comment: 10 pages, UR-1235, ER40685-687, (figures not included

Technological Upgradation in the Informal Manufacturing Sector: Possibilities and Problems

The informal sector in India has consolidated its position in the economy instead of fading away with time. It has taken up the challenges of the new economic dispension with vigorous competitiveness and amazing adaptation & enthusiasm. However, low labour productivity is one of the serious problems related to this sector. It is argued that technological upgradation is likely to solve this problem substantially. This paper attempts to identify the areas within the informal manufacturing sector where such technological upgradation would be fruitful. Several segments and activity groups are identified as Target groups both at the National and Regional level. Associated policies should address availability of proper technology, resource needs for technological upgradation and promoting formal-informal linkages.Informal Sector; Regional Disparity; Productivity; Technology

Complicating Non-Indigeneities and Other Considerations around Race in the Art and Design University

Ce texte examine les complications de la nomenclature entourant la formation d’identités autochtones et non autochtones dans le milieu académique de l’art et du design. L’argument principal est que les contextes coloniaux historiques créent un système binaire où les non-Autochtones sont toujours perçus comme étant des colons blancs, effaçant ainsi les autres personnes racialisées et leur relation à l’autochtonéité. Ce texte historicise également la sous-représentation d’enseignant.e.s racialisé.e.s dans les écoles d’art et de design et cherche à identifier des modèles efficaces aptes à rectifier cette inégalité. Suivant les principes de la théorie critique raciale et intégrant une critique des études critiques blanches, ce texte aborde des possibilités d’actions en matière d’équité à la lumière de la Commission de vérité et de réconciliation, et s’achève avec de brefs exemples de projets pouvant illustrer une voie progressiste à suivre

More on Symmetries in Heavy Quark Effective Theory

We present a general classification of all normal and ``chiral" symmetries of heavy quark effective theories. Some peculiarities and conondrums associated with the ``chiral" symmetries are discussed.Comment: 15 pages, preprint UR-1320, ER40685-77

Factor XII deficiency - A rare coagulation disorder

Severe coagulation factor XII (FXII) deficiency is a very rare, mysterious, and not well-known inherited condition. Unlike other coagulation factor deficiencies, it is usually asymptomatic in most of the cases. Congenital FXII deficiency is the most common cause of an isolated prolongation of the activated partial thromboplastin time in a non-bleeding child or adult; consequently, most patients are detected during a routine pre-operative coagulation study. Surprisingly, it does not lead to abnormal bleeding, but some cases of severe FXII deficiency experiences thrombotic events in their lifetime. There are only a few reports of FXII deficiency in literature. We are reporting a case of congenital FXII deficiency in a 7-month-old child

Computational Fluid Dynamics in Aerospace Industry in India

The role of computational fluid dynamics (CFD) in the design of fighter aircraft, transport aircraft, launch vehicle and missiles in India is explained. Indigenous developments of grid generators, 3-D Euler and Navier-Stokes solvers using state-of-the-art numerical techniques and physical models have been described. Applications of these indigenous softwares for the prediction of various complex aerodynamic flows over a wide range of Mach number, angle of attacks, are presented. Emergence of CFD methods as an efficient tool for aerospace vehicle design is highlighted.Defence Science Journal, 2010, 60(6), pp.639-652, DOI:http://dx.doi.org/10.14429/dsj.60.58

GRID INTEGRATION OF SOLAR PHOTOVOLTAIC SYSTEM USING 25LEVEL SUB-MULTILEVEL INVERTER.

The sub-multilevel electrical inverter could be a replacement topology for multilevel Inverters that are improved or advanced multilevel inverter topology. The projected sub-multilevel inverter uses a reduced range of switching devices and series association within the Power circuit while not compensating the levels. The multilevel inverters are within the center of attraction for the researchers in recent years. this is often owing to it holds advantageous feature to produce improved power quality. The proposed scheme of 25Level sub-multilevel electrical inverter tends to produce a generalized kind to the multilevel inverters that may produce a nearly sinusoidal output voltage. output voltage quality depends on the number of voltage levels of the inverter. Special attention is required to induce the most effective sub-multilevel concerning criteria just like the range of switches, standing voltage on the switches, the range of DC voltage sources, number of output voltage levels on switches and so. the foremost motivation behind this inverter topology is to realize the high power quality, low total harmonic distortion, less magnetic attraction interference, lesser the higher power stability, and reliability. The Simulation strategies of voltage responses and THD responses for asymmetric and symmetric photovoltaic array associated with the three-phase 25-level CSMLI(cascaded Sub- multilevel Inverters) are being carried under the MATLAB environment
