Recognition of human faces is a very important task in many applications such as authentication and surveillance. An efficient face recognition system with face image representation using averaged wavelet and wavelet packet coefficients, Discriminative Common Vector (DCV) and modified Local Binary Patterns (LBP) and recognition using radial basis function (RBF) network is presented. Face images are decomposed by 2-level wavelet and wavelet packet transformation. The discriminative common vectors are obtained for averaged wavelet. The new proposed LBP operator is applied on the obtained DCV and also applied on averaged wavelet packet coefficients of all the samples of a class. The histogram values obtained from the LBP are recognized using RBF network. The proposed work is tested on three face databases such as Olivetti Oracle Research Lab (ORL), Japanese Female Facial Expression (JAFFE) and Essex face database. The proposed method results in good recognition rates along with less training time because of the extracted discriminant input from the preprocessing steps involved in the proposed work. © 2013 Springer International Publishing.

This study was undertaken to develop an efficient single step chromatographic method for purification of C-phycocyanin (CPC) from species of Oscillatoria tenuis. Purification of CPC involves a multistep treatment of the crude extract by precipitation with ammonium sulphate, followed by gel filtration chromatography. Pure CPC was finally obtained from O. tenuis with purity ratio (A620/A280) 4.88. SDS-PAGE of pure CPC yielded two bands corresponding to α and β subunits; the molecular weight of α subunit is 17.0 kDa, whereas the molecular weight of β subunit is 19.5 kDa. Fluorescence and phase contrast microscopy revealed characteristic apoptotic features like cell shrinkage, membrane blebbing, nuclear condensation and DNA fragmentation. CPC exhibited antioxidant and antiproliferative activity against human cancer cells through apoptosis; nuclear apoptosis induction was accompanied by G0/G1 phase arrest and DNA fragmentation. CPC is a natural pigment with potential as an anticancer agent. © 2013 Elsevier Ltd. All rights reserved.

The continuous use of inorganic fertilizers over a period of time cannot sustain the crop yield for a long time, in view of their harmful effects on soil aggregation, and poor root anchorage for normal nutrient and moisture uptake. The organic manures play an important role in supplying macro and micronutrients and improve the physical, chemical and biological property of the soil. The present study was undertaken to study the effect of organic nutrients supplementing through foliar spray of panchakavya (5 and 10%), vermiwash (10 and 15%) and seriboost (0.2%) on 15, 25 and 35 days after pruning following basal doses of vermicompost and inorganic fertilizers in normal recommendation in mulberry garden. The treatment of panchakavya and vermiwash showed better performance in mulberry growth parameter viz., number of shoots/plant, total biomass and leaf yield. The average incidence of pest tukra mealy bug Maconellicoccus hirsutus (Green), Pseudodendrothrips mori, leaf webber D. pulverulentalis were minimum in the treatment of panchakavya and vermiwash. On the food consumption and utilization of Bombyx mori L. larvae (CSR2 x CSR4) fed on leaves treated with panchakavya, vermiwash and seriboost revealed that with advancing instars, irrespective of the treatment food consumption increased, but the pattern of food consumption differed significantly. The rate of feeding (Cr), Assimilation (Ar), and production (Pr) were higher in larvae treated with panchakavya (10%) and vermiwash (15%), over control. The assimilation efficiency and larval growth of the larvae fed on leaves treated with panchakavya, vermiwash and Seriboost increased over control. © JBiopest.

A graph G of size q is odd graceful, if there is an injection φ from V(G) to {0, 1, 2,..., 2q-1} such that, when each edge xy is assigned the label or weight |f(x)-f(y)|, the resulting edge labels are {1, 3, 5,..., 2q-1}. This definition was introduced in 1991 by Gnanajothi [3], who proved that the graphs obtained by joining a single pendant edge to each vertex of Cn are odd graceful, if n is even. In this paper, we generalize Gnanajothi's result on cycles by showing that the graphs obtained by joining m pendant edges to each vertex of Cn are odd graceful if n is even. We also prove that the subdivision of ladders S(Ln) (the graphs obtained by subdividing every edge of Ln exactly once) is odd graceful. © 2011 Copyright Taylor and Francis Group, LLC.

The results of a survey to investigate the diversity of weed flora of mulberry garden in southern Tamil Nadu (Tirunelveli district) under irrigated condition are described and details of weed species including common and vernacular names, relative density (%), family abundance (number of species/ family) and their life form percentage are given. Total numbers of 27 weed species were recorded from 26 genera and 15 families. Among these weed species the relative density was recorded highest with Cyperus rotundus (18.9%) followed by Trianthema portulacastrum (15.2%), Cynodon dactylone (10.3%), Tridax procumbens (9.4%), Acalypha indica (6.6%), Parthenium hysterophorus (5.8%), Tribulus terrestris (4.9%),Dactyloctenium aegyptium (4.1%) and Euphorbia hirta (3.65%). The dominant families were Poaceae and Amaranthaceae contributed 4 species each followed by Asteraceae and Euphorbiaceae (3 species each) and Cyperaceae and Malvaceae (2 species each). Most of the species recorded were annual (63%) followed by annual perennial 22% and perennial (15%).
