In this paper, a new adaptive learning rate algorithm to train a single hidden layer neural network is proposed. The adaptive learning rate is derived by differentiating linear and nonlinear errors and functional constraints weight decay term at hidden layer and penalty term at output layer. Since the adaptive learning rate calculation involves first order derivative of linear and nonlinear errors and second order derivatives of functional constraints, the proposed algorithm converges quickly. Simulation results show the advantages of proposed algorithm. © 2012 IEEE.

Municipal solid waste (MSW) was vermicomposted in combination with cowdung (CD) using Perionyx ceylanensis for 50. days. The decomposition rate of 55-78% was observed in different vermibed substrates, the highest being CD followed by 10:1 ratio of CD. +. MSW. The C/N ratio was reduced from 41.8 to 17.6 and 38.8 to 15.4 in MSW. +. CD (10:1) and CD, respectively. The difference in the final C/N ratio between MSW. +. CD (10:1) and CD vermicompost was not significant (p<0.05). The important nutrients, NPK showed significantly (p<0.05) higher contents in vermicomposts than worm-unworked composts. The degradation rate of cellulose and lignin was 37% and 12%, respectively, in 10:1 vermibed mix with P. ceylanensis. The bacterial, fungal and actinomycetes population in vermicompost was significantly higher than in the compost. The biomass, number and cocoons of P. ceylanensis collected after 50. days showed increase with the increase of CD incorporation in MSW. © 2011 Elsevier Ltd.

Problem statement: Antibiotic susceptibility is still the best way for bacterial pathogen escape mechanism against immunity. Approach: In the present investigation, bacterial pathogens like Staphylococcus aureus, Escherichia coli, Aeromonas hydrophila, Klebsiella and Pseudomonas aeruginosa were used to screen antibiotic susceptibility and immunomodulatory potential. Results: All the test pathogens were sensitive to all the test antibiotics 11±2 mm) except penicillin. The conditions for the preparation of antigens of intact natural composition and conformation from pathogens (whole cell and heat killed), were determined using Swiss albino mice (Balb/C) as experimental species. Immunomodulatory potential of test pathogens were screened using animal model. Test pathogen decreases the body weight comparing that of normal mice, some notable changes were also noted in activity, growth, water consumption, feed consumption. Antibody titre level in animal serum decreased upto 50% in whole cell pathogen and heat killed pathogen treated animals. Conclusion: The five pathogens administered animals, decrement in B-lymphocyte was much pronounced in Pseudomonas aeruginosa followed by Escherichia coli, Staphylococcus aureus, Klebsiella sp., Aeromonas hydrophila in the 5 week. Pathogen treated mice showed an IgG suppressive effect. It is found to be suppressive to T cell production, so induction in cell mediated immunity has confirmed pathogenic potential of test pathogens. All these test pathogenic strains were remarkably suppressing immune system of pathogen exposed animals. © 2010 Science Publications.

Attempt was made to standardize the regeneration protocol. Medium was optimized for callusing, organogenesis and rooting of Vitex leucoxylon. Compact and greenish callus from internodal segments was achieved when stem segments were cultured on Murashige and Skoog (MS) medium fortified with 5.37 μM NAA + 2.22 μM BAP. In vitro regeneration of shoot buds was achieved from internodal callus cultured on MS medium supplemented with 13.30 μM BAP along with 5.37 μM NAA and/or 8.90 μM KN with 2.69 μM NAA. Regeneration and multiplication rate was high in MS medium containing 8.64 μM GA3 and 7.20 μM BAP. Elongated shoots were isolated and cultured on 1/2 strength MS medium supplemented with different concentrations of indole 3-butyric acid (IBA) for root induction. Higher degree of rooting was obtained on MS with 4.90 μM IBA. Rooted plantlets were hardened and successfully established using garden soil. This is the first report dealing with in vitro regeneration system for V. leucoxylon L. © 2010 Academic Journals.

Aluminium monoxide (AlO) is widely known for its astrophysical significance. An analysis of the prominent lines of the (2,3;3,2;3,4;4,5;4,3;5,6;6,7) bands of the B2Σ+-X2Σ+ transition with those of sunspot umbral spectral lines suggests that the AlO molecule appears to be a non-negligible component of sunspot umbrae. Results of a recent (2008) rotational analysis were used to carry out the study. The effective rotational temperature determined for the above lines in the sunspot umbral spectrum is found to be of the order of 2900 K. The radiative-transition parameters that include Franck-Condon (FC) factors, r-centroids, electronic-transition moment, Einstein coefficient, absorption-band oscillator strength, and radiative lifetime have been estimated for the experimentally known vibrational levels using the Rydberg-Klein-Rees (RKR) potential. © 2013 Springer Science+Business Media Dordrecht.
