Childhood vitiligo differs from adult in many clinical parameters. The objective of the current study was to clinicoepidemiologic profile childhood and compare various characteristics childhood- later-onset vitiligo. presentation examined analyzed 762 individuals attending Dermatology Clinic Government Medical College, Haldwani, a referral center for Kumaun region Uttarakhand state, India, between January 2006 December 2010. Of with vitiligo, 268 (35.2%) were children: 152 (56.7%) female 116...
Piebaldism is a rare autosomal dominant disorder of melanocyte development characterized by congenital white forelock and multiple symmetrical stable hypopigmented or depigmented macules. We report family with piebaldism affecting three successive generations also review the literature.
In this paper a 3.2 5 kWP grid connected single stage solar photovoltaic system with multilevel inverter and real time weather conditions is simulated on the MATLAB SIMULINK platform. DC-DC converter completely avoided, voltage stabilization, maximum power point tracking DC to AC conversion are done through only inverter. Five level five switches developed further increase each two levels in output waveform one more additional switch be added. The 1-Φ integrated 1-Φ, 230V, 50 Hz supply from...
Vitiligo is a common, acquired, pigmentary disorder characterized by loss of melanocytes resulting in white spots. This disease carries lot social stigma India.To study the clinico-epidemiological profile vitiligo patients Kumaun region Uttarakhand state India.The clinical presentation was examined and analyzed 762 attending Dermatology outdoor Government Medical College, Haldwani, which referral centre for India.Male female were found to be affected almost equally. It observed that onset...
A steady state superconducting tokamak (SST-1) has been commissioned after the successful experimental and engineering validations of its critical sub-systems. During 'engineering validation phase' SST-1; cryostat was demonstrated to be leak-tight in all operational scenarios, 80 K thermal shields were uniformly cooled without regions 'thermal runaway hot spots', toroidal field magnets their nominal conditions charged up 1.5 T at major radius. The further assembled SST-1 machine shell a...
