Net-charge fluctuations in Pb-Pb collisions at √sNN=2.76 TeV

Abstract: We report the first measurement of the net-charge fluctuations in Pb-Pb collisions at \surd s_NN 2.76 TeV, measured with the ALICE detector at the CERN Large Hadron Collider. The dynamical fluctuations per unit entropy are observed to decrease when going from peripheral to central collisions. An additional reduction in the amount of fluctuations is seen in comparison to the results from lower energies. We examine the dependence of fluctuations on the pseudo-rapidity interval, which may account for the dilution of fluctuations during the evolution of the system. We find that the ALICE data points are between the theoretically predicted values for a hadron gas and a Quark-Gluon Plasma.

Larvicidal activity of leaf extract of Millingtonia hortensis (Family: Bignoniaceae) against Anopheles stephensi, Culex quinquefasciatus and Aedes aegypti.

Abstract: Mosquitoes are the principal vectors of malaria and other vector borne diseases and contribute to major disease burden in India. Disease transmission can be interrupted by controlling the vectors using various methods. However, the extensive and unbalanced use of chemical insecticides have created problems like enhancing resistance of mosquito population to synthetic insecticides, pollution of environment and adverse effects on the non-target flora and fauna inhabiting the same aquatic habitat. These steadily growing problems, demand an intensive search for new products that are environmentally safe, targetspecific and degradable.

Discriminant Analysis Applied to Establish Major-Element Field Boundaries for Tectonic Varieties of Basic Rocks

Abstract: The statistical method of linear discriminant analysis has been applied to distinguish Pliocene to Recent basic rocks on the basis of their major-element composition. Studied basic rock suites are from four tectonic settings: island arc, continental rift, ocean island, and mid-ocean ridge. Field boundaries were derived by computing probability functions replacing the past practice of fitting lines by "eye." Highly successful discrimination diagrams have been obtained. A testing set shows that the rate of correct classification ranges from 76% to 96%, and from 80% to 92% when three and four tectonic groups are considered at a time, respectively. The high potential of this approach to identify different tectonic settings for basic rocks is only reduced by the complex tectonic history shown by a few of the compiled samples, by crustal contamination effects in some basic rock samples, and the similarities of mantle sources tapped in different tectonic settings.

π0 and η meson production in proton-proton collisions at √s = 8 TeV

Abstract: An invariant differential cross section measurement of inclusive $$\pi ^{0}$$ and $$\eta $$ meson production at mid-rapidity in pp collisions at $$\sqrt{s}=8$$ TeV was carried out by the ALICE experiment at the LHC. The spectra of $$\pi ^{0}$$ and $$\eta $$ mesons were measured in transverse momentum ranges of $$0.33.5$$ $$\text{ GeV/c }$$ . However, a deviation from this empirical scaling rule is observed for transverse momenta below $$p_{ \text{ T }} <3.5$$ $$\text{ GeV/c }$$ in the $$\eta /\pi ^0$$ ratio with a significance of $$6.2\sigma $$ .
