Electrophoretic studies on serum proteins of oil sardine (Sardinella longiceps) and Mackerel (Rastrelliger kanagurta)

Oil sardine blood tests against human typing sera indicated A - positive, A - negative and B - negative. The blood of mackerel is antigenically negative both for A and B. Elect rophoretic studies on serum proteins revealed the existence of genetically different groups of oil sardine and mackerel on the south-west coast of India

Electrophoretic characteristics of oil sardine (Sardinella longiceps) and mackerel (Rastrelliger kanagurta) eye lens proteins

Electrophoresis of eye lens protei ns of oil sardine and mackerel showed separation of proteins into three and four components, indicating the heterogenous nature of the population

Fertilization, Soils and Cultural Practices CROPLOGGING AS A MEANS OF CONTROLLING SUGARCANE FERTILIZATION IN SMALL HOLDINGS

ABSTRACT The results of logging sugarcane crops in small holdings distributed over 6 sugar factory zones in Andhra Pradesh (India) have been presented in order to indicate the relationship between nutrient indices of crops given different levels of N and cane yield. I n the 152 holdings about which information has been presented in this paper, 3 varieties, viz, Co 419, Co 527 and Co 997 were involved. The findings indicated that 3-6 leaf sheath moisture in the first 4 months and at harvest may be taken as a reliable guide for prediction of cane yields and quality of the crop, respectively. Completion of N fertilization within 4 months and provision of adequate irrigation, especially, in this period were noted to result in maintenance of optimum sheath moisture values at appropriate times, leading to good cane yields of satisfactory quality

INFLUENCE OF CARBON AND NITROGEN SOURCE ON GROWTH, DON AND NIV PRODUCTION BY TWO SPECIES OF FUSARIUM ISOLATED FROM FINGER MILLETS

Objective: Influence of different carbon [C] and nitrogen [N] source on the growth and Deoxynivalenol [DON] and Nivalenol [NIV] production by Fusarium aethiopicum and Fusarium culmorum was investigated.Methods: Seven days old monosporic cultures of F. aethiopicum strain GSKUMB [KJ21085] and F. culmorum strain GSKUMB [KJ190159] were grown in CYA broth and incubated at 27±2°C on the rotary shaker at 120 rpm for 21 days. At the end of incubation period, cultures were harvested for determination of fungal growth (biomass). The resultant culture filtrates were extracted twice with ethyl acetate and concentrated. One ml of final concentrate in methanol was employed for detection of DON and NIV with the help of RP-HPLC.Results: The highest amount of DON and NIV were produced by F. aethiopicum in the presence of D-mannose and D-galactose as C source, while the highest amount of biomass was recorded on maltose and succinic acid. F. culmorum produced maximum amount of toxins in the presence of D-glucose, D-mannitol and D-fructose. Sodium nitrate was most favorable nitrogen source as it induced maximum amount of toxins by F. aethiopicum, while L-methionine, L-asparatic acid and L-tryptophan were next preferred N source. In contrast, highest biomass of fungus was obtained with L-lysine, L-glutamine and L-tyrosine. F. culmorum produced maximum amount of toxin and biomass with potassium nitrate and L-tyrosine respectively.Conclusion: Present species of Fusarium differed varied both in toxins (DON, and NIV) and biomass production. Their response of fungi under investigation towards C and N sources is also varied.Â

A Neural Network Approach to Key Frame Extraction

We present a neural network based approach to key frame extraction in the compressed domain. The proposed method is an amalgamation of both the MPEG-7 descriptors namely motion intensity descriptor and spatial activity descriptor. Shot boundary detection and block motion estimation techniques are employed prior to the extraction of the descriptors. The motion intensity (“pace of action”) is obtained using a fuzzy system that classifies the motion intensity into five categories proportional to the intensity. The spatial activity matrix determines the spatial distribution of activity (“active regions”) in a frame. A neural network is used to pick those frames as key frames which have high intensity and maximum spatial activity at the center of the frame. Results are compared against two well-known key frame extraction techniques to demonstrate the advantage and robustness of the proposed approach. Results show that the neural network approach performs much better than selecting first frame of the shot as a key frame and selecting middle frame of the shot as a key frame methods

Antimicrobial Activity of Suaeda monoica (Forsst ex Geml) against Human and Plant Pathogens

ABSTRACT Antimicrobial activity of the halophyte Suaeda monoica (Forsst ex Geml) was studied using leaf and shoot extracts, on the various test microorganisms, including multiple antibiotic resistant bacteria and phytopathogens. Antimicrobial activity of the extracts was determined by the Well Diffusion Method. The experimental results concluded that the hexane, methanol and water extracts of S. monoica leaves have greater potential as antimicrobial compounds against microorganisms and they can be used in the treatment of infectious diseases caused by resistant pathogenic microorganisms

Formation constants of binary & ternary chelates of Ln(III) with maltol & kojic acid in presence of amino carboxylic acids

174-175The formation constants of binary and ternary systems involving 3-hydroxy-2-methyl-4-pyrone (HMP) (maltol) and 5-hydroxy-2-hydroxymethyl-4-pyrone (HOMP) (kojic acid), with lanthanide metal ions [La(III), Pr(II), Nd(III), Gd(III), Dy(III) and Y(III)] in the presence of iminodiacetic acid (IMDA), hydroxyethyliminodiacetic acid (HIMDA) and nitrilotriacetic acid (NTA) have been determined in aqueous medium at 30°C and μ = 0.1 M (NaClO4). The order of stabilities of ternary systems is: HMP > HOMP and IMDA > HIMDA > NTA. These are explained in the light of the basi-cities of the Iigands and charge neutralisation

Management of leaf spot of turmeric (Curcuma longa L.) incited by Colletotrichum capsici through fungicides

An experiment was conducted at Kammarpally (Andhra Pradesh) to evaluate the efficacy of four fungicides viz., Propiconazole (0.1%), Hexaconazole (0.1%), Tricyclazole (0.1%) and Carbendazim + Mancozeb (0.1%) for the management of leaf spot disease (Colletotrichum capsici) of turmeric (Curcuma longa L.). Rhizome treatment with Carbendazim + Mancozeb (0.1%) gave the best results for germination (90.52%) and rhizome treatment and foliar application of Propiconazole (0.1%) at 45 and 90 days after planting (DAP) were significantly superior in reducing the disease index (20.01%) of leaf spot disease and increasing the fresh rhizome yield (17.13 t ha-1) as compared to other fungicides tested. The high cost – benefit ratio was achieved in rhizome treatment and foliar application of Carbendazim + Mancozeb at 45 and 90 DAP (1:1.92). &nbsp
