Cellularity of Wreath Product Algebras and AA--Brauer algebras

A cellular algebra is called cyclic cellular if all cell modules are cyclic. Most important examples of cellular algebras appearing in representation theory are in fact cyclic cellular. We prove that if $A$ is a cyclic cellular algebra, then the wreath product of $A$ with the symmetric group on $n$ letters is also cyclic cellular. We also introduce $A$--Brauer algebras, for algebras $A$ with an involution and trace. This class of algebras includes, in particular, $G$--Brauer algebras for non-abelian groups $G$. We prove that if $A$ is cyclic cellular then the $A$--Brauer algebras $D_n(A)$ are also cyclic cellular

Impact of Cyclone Vardha on fishers and their livelihoods

The Vardah Cyclone struck Chennai, Kanchipuram and Thiruvallur coastal districts of Tamil Nadu on 12th December 2016 and impacted nearly 25000 fisher families. Wind speed of 140 km/hour and tidal waves inundated the low lying areas of coastal villages causing very heavy damage

Isolation and identification of fungal communities from vegetable wastes composts,

Compost preparation was carried out at Department of Botany, Bangalore University Bangalore during 2013 and 2014 by using Cabbage, tomato fresh cow dung and mixed vegetable waste. The experiments were laid down in a completely replicated randomized block design with three replication for each treatment. The qualitative and quantitative composition of individual vegetable composts (Tomato waste, Cabbage waste and mixed vegetable waste) were used for the isolation. The fungi were isolated on Potato Dextrose Agar (PDA) and at different temperature 50-55°C. Substantially qualitative differences in the species composition of different vegetables composts were observed. A total of 11 entities were isolated 3 from tomato waste compost, 2 from cabbage waste compost and 4 from mixed vegetable waste at 50°C and 3 at 55°C respectively. This report demonstrates that the qualitative and quantitative characterization of individual composts and fungal communities essential for best industrial application

Marine Biodiversity Museum (A Designated National Repository) Catalogue

The Central Marine Fisheries Research Institute, Cochin was recognized as a 'Designated National Repository' by the Government of India, in December 2007 in consultation with the National Biodiversity Authority under the Biological Diversity Act, 2002. A Designated National Repository (DNR) is an Institution authorised to keep in safe custody specimens of different categories of biological material. The Museum offers a glimpse of the bioresources of the Indian seas. Currently the museum houses six holotype specimens, 878 finfish species, 136 crustaceans, 217 molluscs, 44 echinoderms, 162 corals, 12 sponges, 20 ascidians, 82 seaweeds and 8 seagrasses besides a dolphin and three Antarctic birds. The Museum is open to scientists, teachers, students and the general public. The fact that students form more than 85% of the visitors highlights the role played by the Museum in education. A catalogue of the specimens available in the Museum has been prepared as it is expected to be of immense use to those engaged in marine biodiversity studies. I sincerely thank Dr. G. Syda Rao, Director, CMFRI whose guidance and encouragement made this a reality

Structural Behavior of Non-Oxide Perovskite Superconductor MgCNi3_{3} at Pressures up to 32 GPa

We report the pressure dependence of the structural parameters of the non-oxide perovskite superconductor MgCNi$_{3}$ up to 32 GPa using a diamond anvil cell and synchrotron x-rays at room temperature. The structure of the compound remains in the Pm-3m cubic symmetry throughout the pressure range. The bulk modulus $B_{0}=156.9\pm0.2$GPa with $B_{0}^{\prime}=9.8$obtained by fitting the pressure-volume data is in good agreement with theoretical calculations reported earlier. An anomalous shift of the (111) and (200) lines observed above 9 GPa indicates a possible local short range distortion that is consistent with earlier studies.Comment: 9 Pages, 3 Figures, 1 Tabl

Structure and Rheology of the Defect-gel States of Pure and Particle-dispersed Lyotropic Lamellar Phases

We present important new results from light-microscopy and rheometry on a moderately concentrated lyotropic smectic, with and without particulate additives. Shear-treatment aligns the phase rapidly, except for a striking network of oily-streak defects, which anneals out much more slowly. If spherical particles several microns in diameter are dispersed in the lamellar medium, part of the defect network persists under shear-treatment, its nodes anchored on the particles. The sample as prepared has substantial storage and loss moduli, both of which decrease steadily under shear-treatment. Adding particles enhances the moduli and retards their decay under shear. The data for the frequency-dependent storage modulus after various durations of shear-treatment can be scaled to collapse onto a single curve. The elasticity and dissipation in these samples thus arises mainly from the defect network, not directly from the smectic elasticity and hydrodynamics.Comment: 19 pages inclusive of 12 PostScript figures, uses revtex, psfrag and epsfig. Revised version, accepted for publication in Euro. Phys. J. B, with improved images of defect structure and theoretical estimates of network elasticity and scalin
