    The main aim was, to design Pit Furnace from the setup of black smithy. As the Smithy setup was not in use so it is converted into Pit Furnace setup. The purpose of using Pit Furnace is to melt nonferrous material. The Nonferrous materials such as Aluminum, Aluminum alloy, Copper, Brass, etc. The Aluminum has less melting point (680á”’ C, 1218á”’F) and cheaper than other. The thermal efficiency of furnace is 13.72% which is obtained by melting 2 kg of Aluminum for 75 minutes. Normally thermal of pit furnace is between 4-19%. The blower is used to supply the air into the furnace chamber to burn the coal. For melting the Aluminum, Crucible should sustain higher temperature so Graphite Crucible is used. This Crucible has thinner wall and have more refractory properties

    Transnational academic mobility and gender

    This is an Accepted Manuscript of an article published by Taylor & Francis in Globalisation, Societies and Education on 24 June 2011, available online: http://wwww.tandfonline.com/10.1080/14767724.2011.577199This paper examines to what extent the participation of researchers in transnational academic mobility, their experiences and perceived outcomes vary by gender. Based on longitudinal statistics, original survey data and semi-structured interviews with former visiting researchers in Germany, the paper shows that the academic world of female researchers tends to be less international than that of their male colleagues, particularly in the natural sciences. This situation has improved since the 1980s but significant variations remain by source country, subject, career stage and length of stay. The paper argues that the underlying reasons go far beyond direct gender relationships and suggests that conceptualising transnational academic mobility as an integral part of mobilisation processes in Latourian 'centres of calculation' underlines the need for making this experience accessible to the widest possible range of researchers. © 2011 Taylor & Francis

    Anemia prevalence in women of reproductive age in low- and middle-income countries between 2000 and 2018

    Anemia is a globally widespread condition in women and is associated with reduced economic productivity and increased mortality worldwide. Here we map annual 2000–2018 geospatial estimates of anemia prevalence in women of reproductive age (15–49 years) across 82 low- and middle-income countries (LMICs), stratify anemia by severity and aggregate results to policy-relevant administrative and national levels. Additionally, we provide subnational disparity analyses to provide a comprehensive overview of anemia prevalence inequalities within these countries and predict progress toward the World Health Organization’s Global Nutrition Target (WHO GNT) to reduce anemia by half by 2030. Our results demonstrate widespread moderate improvements in overall anemia prevalence but identify only three LMICs with a high probability of achieving the WHO GNT by 2030 at a national scale, and no LMIC is expected to achieve the target in all their subnational administrative units. Our maps show where large within-country disparities occur, as well as areas likely to fall short of the WHO GNT, offering precision public health tools so that adequate resource allocation and subsequent interventions can be targeted to the most vulnerable populations.Peer reviewe

    Measurement of the azimuthal anisotropy of Y(1S) and Y(2S) mesons in PbPb collisions at √S^{S}NN = 5.02 TeV

    The second-order Fourier coefficients (υ2_{2}) characterizing the azimuthal distributions of ΄(1S) and ΄(2S) mesons produced in PbPb collisions at sNN\sqrt{s_{NN}} = 5.02 TeV are studied. The ΄mesons are reconstructed in their dimuon decay channel, as measured by the CMS detector. The collected data set corresponds to an integrated luminosity of 1.7 nb−1^{-1}. The scalar product method is used to extract the υ2_{2} coefficients of the azimuthal distributions. Results are reported for the rapidity range |y| < 2.4, in the transverse momentum interval 0 < pT_{T} < 50 GeV/c, and in three centrality ranges of 10–30%, 30–50% and 50–90%. In contrast to the J/ψ mesons, the measured υ2_{2} values for the ΄ mesons are found to be consistent with zero

    Measurement of prompt D0^{0} and D‟\overline{D}0^{0} meson azimuthal anisotropy and search for strong electric fields in PbPb collisions at root SNN\sqrt{S_{NN}} = 5.02 TeV

    The strong Coulomb field created in ultrarelativistic heavy ion collisions is expected to produce a rapiditydependent difference (Av2) in the second Fourier coefficient of the azimuthal distribution (elliptic flow, v2) between D0 (uc) and D0 (uc) mesons. Motivated by the search for evidence of this field, the CMS detector at the LHC is used to perform the first measurement of Av2. The rapidity-averaged value is found to be (Av2) = 0.001 ? 0.001 (stat)? 0.003 (syst) in PbPb collisions at ?sNN = 5.02 TeV. In addition, the influence of the collision geometry is explored by measuring the D0 and D0mesons v2 and triangular flow coefficient (v3) as functions of rapidity, transverse momentum (pT), and event centrality (a measure of the overlap of the two Pb nuclei). A clear centrality dependence of prompt D0 meson v2 values is observed, while the v3 is largely independent of centrality. These trends are consistent with expectations of flow driven by the initial-state geometry. ? 2021 The Author. Published by Elsevier B.V. This is an open access article under the CC BY licens
