    Moringa oleifera Lam. is a vegetal species with great potential to use as food, medicine and forage as well as water clarifying and decontamination agent, biofuel, among others. Low cost techniques for seedling production using regional residues are useful to introduce this species in low-income communities. This research aimed to evaluate the nutritional responses and growth of moringa seedlings cultivated in substrates with different concentrations of green coconut fiber (GCF) associated to organic compounds (OC). The experiment was performed in randomized blocks. Two organic compounds were tested: the urban waste compost (UWC) and earthworm compost (EC) associated with GCF in various volumetric proportions (OC: GCF): 0: 100; 25:75; 50:50; 75:25 and 100:0%. The data after 51 days of cultivation showed that the increase of the concentration of GCF in relation to the organic compound decreased height, dry biomass, Dickson Quality Index and the contents of N, P, K, Ca and Mg of the seedlings. There was no difference for these characteristics between the use of UWC and the EC. The substrate with 100% of GCF without complementary fertilizers caused symptoms of N deficiency in the moringa seedlings.63454555

    Search for the associated production of the Higgs boson with a top-quark pair

    A search for the standard model Higgs boson produced in association with a top-quark pair t t ¯ H (tt¯H) is presented, using data samples corresponding to integrated luminosities of up to 5.1 fb −1 and 19.7 fb −1 collected in pp collisions at center-of-mass energies of 7 TeV and 8 TeV respectively. The search is based on the following signatures of the Higgs boson decay: H → hadrons, H → photons, and H → leptons. The results are characterized by an observed t t ¯ H tt¯H signal strength relative to the standard model cross section, μ = σ/σ SM ,under the assumption that the Higgs boson decays as expected in the standard model. The best fit value is μ = 2.8 ± 1.0 for a Higgs boson mass of 125.6 GeV
