Biofertilizing Efficiency of Brown and Green Algae on Growth, Biochemical and Yield Parameters of Cyamopsis tetragonolaba (L.) Taub.
The effect of liquid extracts of marine algae Sargassum wightii and Ulva lactuca when applied as soil drench to cluster bean plant increased the growth, biochemical and yield of the plant. Liquid extracts of Sargassum wightii (1.5%) and Ulva lactuca (1.0%) was found to have maximum influence on growth parameters viz., shoot length, root length, total fresh and dry weight, leaf area and moisture content. Further, there was a significant increase in biochemical parameters such as photosynthetic pigments, protein content, amino acids, reducing sugar, ascorbic acid, nitrate reductase activity. Similarly, enhancement in yield parameters such as number of pods per plant, pod weight, pod length and number of seeds per pod were also observed. Higher concentrations of both algal extracts were found to show inhibitive effect on all above parameters studied
Electrostatically tuned quantum superconductor-metal-insulator transition at the LaAlO3/SrTiO3 interface
Recently superconductivity at the interface between the insulators LaAlO3 and
SrTiO3 has been tuned with the electric field effect to an unprecedented range
of transition temperatures. Here we perform a detailed finite size scaling
analysis to explore the compatibility of the phase transition line with
Berezinskii-Kosterlitz-Thouless (BKT) behavior and a 2D-quantum
phase(QP)-transition. In an intermediate regime, limited by a gate voltage
dependent limiting length, we uncover remarkable consistency with a
BKT-critical line ending at a metallic quantum critical point, separating a
weakly localized insulator from the superconducting phase. Our estimates for
the critical exponents of the 2D-QP-transition, z=1 and nu=0.66, suggest that
it belongs to the 3D-xy universality class.Comment: 10 pages, 10 figure
Lifelogging user study:bystander privacy
Automatically and passively taking pictures (using lifelogging devices such as wearable cameras) of people who don’t know they’re having their picture taken raises a number of privacy concerns (from a bystander’s perspective). We conducted a study focussing on the bystanders’ concerns to the presence of augmented reality wearable devices in two contexts (one formal and one informal). The results suggests the need to embed privacy enhancing techniques into the design of lifelogging applications, which are likely to depend upon an array of factors, but not limited to the context of use, scenario (and surroundings), and content
Charged Current Universality in the MSSM
We compute the complete one-loop contributions to low-energy charged current
weak interaction observables in the Minimal Supersymmetric Standard Model
(MSSM). We obtain the constraints on the MSSM parameter space which arise when
precision low-energy charged current data are analyzed in tandem with
measurements of the muon anomaly. While the data allow the presence of at least
one light neutralino, they also imply a pattern of mass splittings among first
and second generation sleptons and squarks which contradict predictions of
widely used models for supersymmetry breaking mediation.Comment: 4 pages, 2 figure
Genetic diversity studies in groundnut genotypes (Arachis hypogaea L.)
The present study was done to study the extent of diversity among the released and popular varieties of India and
advanced cultures in groundnut. D2 analysis for 15 characters resulted in the formation of nine clusters among the 30
genotypes studied. Highest intra-cluster distance was recorded for cluster VI followed by III, V, II and VII. Maximum
inter-cluster distance was recorded between clusters VIII and IX followed by between clusters III and IX and between
clusters VII and VIII. Based on mean performance, intra and inter-cluster distance, the genotypes of cluster VI (ALR
1 and COG0539) could be used for increasing the shelling per cent, oil content, pod yield / plant and no. of primary
branches / plant. The genotypes in cluster III (CO 1, COG0549 and BSR 2) can be used for improving number of
mature pods/ plant, hundred kernel weight, leaf area index and cluster VIII (JL 24) for total biomass and kernel yield /
plant for trait based improvement programme
Properties of Neutral Charmed Mesons in Proton--Nucleus Interactions at 70 GeV
The results of treatment of data obtained in the SERP-E-184experiment
"Investigation of mechanisms of the production of charmed particles in
proton-nucleus interactions at 70 GeV and their decays" by irradiating the
active target of the SVD-2 facility consisting of carbon, silicon, and lead
plates, are presented. After separating a signal from the two-particle decay of
neutral charmed mesons and estimating the cross section for charm production at
a threshold energy {\sigma}(c\v{c})=7.1 \pm 2.4(stat.) \pm 1.4(syst.)
\mub/nucleon, some properties of D mesons are investigated. These include the
dependence of the cross section on the target mass number (its A dependence);
the behavior of the differential cross sections d{\sigma}/dpt2 and
d{\sigma}/dxF; and the dependence of the parameter {\alpha} on the kinematical
variables xF, pt2, and plab. The experimental results in question are compared
with predictions obtained on the basis of the FRITIOF7.02 code.Comment: 9 pages, 9 figures,3 table
