Electron-Hadron Correlations in pp Collisions at \sqrt{s} = 2.76 TeV with the ALICE experiment

In this work we are studying the relative beauty to charm production in pp collisions at \sqrt{s} = 2.76 TeV, through correlations between electrons from heavy-flavour decay and charged hadrons, with the ALICE detector at the LHC. This study represents a baseline for the analysis in heavy-ion collisions where heavy flavour production is a powerful tool to study the Quark Gluon Plasma (QGP).Comment: Proceeding of the XII HADRON PHYSICS (2012, Bento Gon\c{c}alvez, Brazil) conference. 3 Pages, 4 Figure

Measurements of the correlation between electrons from heavy-flavour hadron decays and light hadrons with ALICE at the LHC

In relativistic heavy-ion physics two-particle correlations provide a very useful tool to investigate the Quark-Gluon Plasma (QGP). This observable is sensitive to several of the properties of the QGP such as resonances, interaction of partons with the medium and collective effects (e. g. elliptic flow). In the present work, the correlation function between electrons from heavy-flavour hadron decays and light hadrons was measured in pp and Pb-Pb collisions (central and semi-central). Furthermore, in pp collisions the relative beauty contribution to the total cross section of electrons from heavy-flavour decays was estimated by comparing the measured correlation with Monte-Carlo templates.Comment: Strangeness in Quark Matter 2013 conference proceedin

Measurements of electrons from heavy-flavour hadron decays in pp, p-Pb and Pb-Pb collisions with ALICE at the LHC

Heavy-flavour hadrons, i. e. hadrons carrying charm or beauty quarks, are a well-suited probe to study the Quark-Gluon Plasma (QGP) in relativistic heavy-ion collisions. For this reason, measurements of electrons from heavy-flavour hadron decays have been performed in pp, p-Pb and Pb-Pb collisions at the LHC with the ALICE detector. Results for the nuclear modification factors ($R_{\rm{pA}}$ and $R_{\rm{AA}}$) support a final-state energy loss of heavy quarks in central Pb-Pb collisions and, in semi-central collisions a positive elliptic flow coefficient $v_{2}$ of electrons from heavy-flavour hadron decays was observed. Furthermore, a double-ridge structure was observed in the measured two-particle angular correlation distribution, triggered by heavy-flavour decay electrons, in high-multiplicity p-Pb collisions relative to low-multiplicity p-Pb collisions and to pp collisions.Comment: Hard Probes 2013 conference proceedin

Eggplant growth as affected by bovine manure and magnesium thermophosphate rates

Plant growth is influenced by nutrient availability. The objective of this research was to study, under greenhouse conditions, eggplant growth as affected by rates of bovine manure and magnesium thermophosphate (g kg-1 and mg kg-1, respectively), according to a "Box central composite" matrix: 4.15-259; 4.15-1509; 24.15-259; 24.15-1509; 0.0-884; 28.3-884; 14.15-0,0; 14.15-1768; 14.15-884. Potassium sulfate (170 mg kg-1) and 200 mL per pot of cow urine solution were applied four times, but the concentration of the last two applications (200 mL/H2O L) was twice of that of the first two. Additional treatments: magnesium thermophosphate without cow urine and triple superphosphate with urea, both with nutrient levels equivalent to the bovine manure, P2O5 and potassium sulfate to the combination 14.15-884. The experimental design consisted of randomized blocks with four replicates. Leaf area (LA) and LA ratio increased as quadratic functions with manure rates, with negative interaction for thermophosphate. Leaf dry matter mass (DMM) had an increasing quadratic function with rates for both fertilizers. The higher combined rates of both fertilizers resulted in the smallest specific leaf area, but also the highest values of shoot and root DMM, total DMM and, with positive interaction in relation to root shoot dry matter ratio. The relative growth rate in stem height, and also in diameter, increased with manure, according to quadratic and linear functions, respectively. The cow urine effect was, in general, lower than that of urea. The plant's overall growth was more influenced by manure. Root DMM and shoot DMM were greater with high K and P.O crescimento em plantas é influenciado pela disponibilidade de nutrientes. O objetivo deste trabalho foi estudar, em abrigo telado, o crescimento da berinjela em função de doses de esterco bovino e termofosfato magnesiano (g kg-1 - mg kg-1, respectivamente), conforme a matriz "composto central de Box": 4,15-259; 4,15-1509; 24,15-259; 24,15-1509; 0,0-884; 28,3-884; 14,15-0,0; 14,15-1768; 14,15-884. Acrescentaram-se sulfato de potássio (170 mg kg-1) e quatro parcelas de 50 mL por vaso de solução de urina de vaca, as duas últimas possuindo concentração de 200 mL L-1 de H2O, o dobro da inicial. Tratamentos adicionais: termofosfato magnesiano sem urina de vaca e superfosfato triplo com uréia, iguais em esterco, P2O5 e sulfato de potássio, à combinação 14,15-884. O delineamento experimental foi em blocos casualizados com quatro repetições. A área foliar (AF) e a razão de AF aumentaram, quadraticamente, com as doses de esterco, porém, a interação com o termofosfato foi negativa. A massa de matéria seca (MMS) de folhas incrementou, quadraticamente, com as doses dos dois insumos. Na combinação das maiores doses de ambos ocorreram a menor AF específica e os maiores valores da MMS da parte aérea, MMS de raízes, MMS total e, por interação positiva, da relação raiz parte aérea. A taxa de crescimento relativo em altura caulinar, e em diâmetro, aumentaram, quadrática e linearmente, somente com o esterco, respectivamente. A urina de vaca teve efeito, em geral, inferior ao da uréia. O crescimento geral da planta foi mais responsivo ao esterco. A MMSR e a MMSPA foram maiores com elevada disponibilidade de K e P no substrato
