Activities of invertase and cellulase as influenced by the application of tridemorph and captan to groundnut (Arachis hypogaea) soil

A laboratory experiment was conducted to study the effect of selected fungicides, tridemorph and captan, at concentrations ranging from 0 to10 kg ha-1 on the activity of invertase and cellulase in a vertisol. The activities of invertase and cellulase were significantly more at tridemorph and captan levels of 2.5 and 5.0 kg ha-1, respectively. But at higher concentrations of 7.5 and 10 kg ha-1 respectively, tridemorph and captan were toxic to both cellulase and invertase activities. In soil samples receiving 2.5-5.0 kg ha-1 of the fungcides, the accumulation of reducing sugar was pronounced more at 20 days, and the activity of the invertase and cellulase was drastically decreased with increasing period of incubation up to 30 and 40 days.Keywords: Fungicides, invertase, cellulase, groundnut, Arachis hypogae

Cytological Effects of Paper Mills Effluents on Somatic Cells of Allium Cepa

The cytological effects of paper mills effluents on somatic cells of Allium cepa were presented. The cytological effect decreased by decreasing the concentration of the effluents. Disturbed metaphase, anaphase and telophase, occurrence of binucleate and tetranucleate cells comprised the most dominant types of abnormalities. Clumping of chromosomes, contracted chromosomes, pleiomorphic and micronuclei formation, cell vacuolation and polyploid cells are found less frequently. The c-mitotic effect and other abnormalities may be due to the action of alkalies, acids and bleaching agents present in the paper mill effluents

Serological diagnosis of pulmonary aspergillosis

Methods for the preparation of antigens from clinically isolated cultures of Aspergillus were standardized. Sera from 25 suspected cases of pulmonary aspergillosis were tested against antigens prepared by us, from 4 strains of A. fumigatus and one strain of A. flavus, using the Ouchterlony double diffusion and immunoelectrophoretic techniques. Of the 25 sera tested, 18 reacted positively with antigens of A.fumigatus, one with A.flavus and 2 with both these species. Antigens of two non-pathogenic Aspergilli included in the study failed to react with any of the sera. Our antigen preparations gave more numerous as well as sharper precipitin lines than the commercial Bencard antigens which were used for comparison. Moreover, mycelial antigens from 48 to 96 h old cultures revealed precipitin lines comparable to that of the routine, 4 week old culture filtrate antigens, thus suggesting that the incubation period for obtaining antigens could be cut down considerably

Highly Selective, Electrically Conductive Monolayer of Nanoparticles on Live Bacteria

Using specific peptide−bacteria affinity, a monolayer of 30 nm Au particle is selectively deposited on live bacteria surface to produce electrically conducting bridges spanning over 12 μm. The conductivity of the monolayer network is further improved by over 10-fold by “electric-field annealing”. The annealing process is explained by a percolation model

IRDO: Iris Recognition by Fusion of DTCWT and OLBP

Iris Biometric is a physiological trait of human beings. In this paper, we propose Iris an Recognition using Fusion of Dual Tree Complex Wavelet Transform (DTCWT) and Over Lapping Local Binary Pattern (OLBP) Features. An eye is preprocessed to extract the iris part and obtain the Region of Interest (ROI) area from an iris. The complex wavelet features are extracted for region from the Iris DTCWT. OLBP is further applied on ROI to generate features of magnitude coefficients. The resultant features are generated by fusing DTCWT and OLBP using arithmetic addition. The Euclidean Distance (ED) is used to compare test iris with database iris features to identify a person. It is observed that the values of Total Success Rate (TSR) and Equal Error Rate (EER) are better in the case of proposed IRDO compared to the state-of-the art technique

Ratio of pions to protons and ratio of neutral to charged interacting particles at mountain altitude of 800 gm/cm<SUP>2</SUP>

Using a combined set-up of a multiplate cloud chamber, an air Cerenkov counter and a total absorption spectrometer, the ratio of pions to protons not associated with large air showers has been determined to be 0&#183;50 &#177; &#183;07 in the energy region 20-40 GeV at an altitude of 800 gm/cm2. In the same energy region the ratio of neutral to charged particles is found to be 0.66 &#177; &#183;07. From the ratio of neutrons to protons deduced from these measurements (i.e., 0&#183;99 &#177; &#183;11), it is concluded that most of the charge excess of nuclear active particles of energies &gt; 20 GeV at mountain altitudes and sea-level is due to pions

Evaluation of pigeonpea genotypes for resistance to pigeonpea sterility Mmsaic Vvrus - B Isolate

Pigeonpea genotypes (89) were evaluated for resistance to Pigeonpea sterility mosaic virus Bangalore isolate (PPSMV-B). Of these, three genotypes, ICP 7035, MAL 14 and MAL 19, were found resistant, and two genotypes, ICP 6997 and ICP 8862, were tolerant to PPSMV-B. All the resistant lines tested negative to virus in enzyme-linked immunosorbent assay (ELISA) using PPSMV polyclonal antiserum. The resistant lines can be used in breeding programme for developing PPSMV-resistant high yielding cultivar

Observations on the nuclear interaction of cosmic ray pions and nucleons of energies ≳ 20 GeV. Part I. Experimental details and results relating to fluctuations in the angular distribution of the secondary particles produced in interactions in carbon

In this paper, which is the first of a series entitled 'Observations on the Nuclear Interactions of Cosmic Ray Pions and Nucleons of Energy ≳ 20 GeV', a description is given of the experimental arrangement, the types of data collected and the methods employed to analyse and classify the data. Results on the fluctuations in the angular distribution of the secondary particles produced in interactions in carbon are also presented and it is shown that these fluctuations are considerably larger in certain cases than what can be accounted for purely from statistical fluctuations in the isotropic and uncorrelated emission of secondaries in the c.m. system of the collision with a target nucleon and in others difficult to be understood on this basis if additional features of these interactions are also considered. It is suggested that 'correlated emission' of secondaries possibly due to final state inter-actions or multiparticle resonances with different 'Q-values' and other properties are perhaps the cause of the observed fluctuations; this is in contrast to the explanation in terms of simple motion of 'fire balls' in the c.m. system as has been generally discussed

ICP 7035 – A Sterility Mosaic Resistant Vegetable and Grain Purpose Pigeonpea Variety

ICP 7035 is a medium duration, non-determinate pigeonpea landrace collected in 1973 from Bedaghat (near Jabalpur), Madhya Pradesh, India. Plants mature in 170-200 days (in south-central regions of India) and, at this stage, reach an average height of 120-140 cm. Each plant produced around 100 pods and each pod contained 5 seeds, which are nutritionally rich and contain high percentages of digestible carbohydrates, vitamins and micronutrients. The large seeds (9-11 mm diameter) had purple seed coats and green cotyledons, and are suitable for consumption as vegetable. The fresh seed contains 8.6% protein, 12% fibre, and 45.7% carbohydrate and starch. The pinkish-purple colour of the pod and seed coat is due to high anthocyanin contents. While the normal sugar level in most pigeon pea cultivars is approximately 5%, the sugar content in ICP 7035 seeds is 8.8%. Decorticated dried split seeds measure 5-6 mm in diameter and 100 dried seeds weigh 19.2 g. The seed contains 19.6% protein, 27.4% dietary fibre, 33% starch and 67% carbohydrate, and has high amounts of copper, calcium, magnesium and phosphorous. Resistance to Pigeonpea sterility mosaic virus in ICP 7035 has a positive impact on yield as a result of negligible crop loss in endemic areas. In the absence of the disease, the yield of ICP 7035 is on a par with the yields of local cultivars. Recently, provisional approval was given for the release of this cultivar in SMD endemic areas of southern Karnataka

Observations on the nuclear interactions of cosmic ray pions and nucleons at energies ≳ 20 GeV Part II. The extremely collimated nuclear interactions

Detailed features of extremely collimated nuclear interactions induced by cosmic ray particles in carbon and brass (belonging to group I as classified in Part I of this series of papers) are presented. These extremely collimated nuclear interactions seem to be preferentially induced by pions rather than by nucleons; also the relative frequency of these seems to be less when brass is used as target compared to the case with carbon as target. The distribution of multiplicities of secondary particles emitted in the forward direction show certain regularities in the case of interactions induced by charged primaries. Observations on the γ-rays associated with these events give support to the interpretation that in these inelastic collisions pions are produced in pairs in the forward direction with low transverse momentum. It is suggested that such a low energy di-pion system could be the same as found in the so-called ABC effect
