Current research evaluated the use of Pinus sp. wood dust from lumber industries wastes on the composition of wood-cement panels. The experiment comprised the manufacture and characterization of wood-cement panels with granulometry-controled wood dust, without any previous treatment, and four…

, We investigate how it is possible to obtain different diffusive regimes from the Continuous Time Random Walk (CTRW) approach performing suitable changes for the waiting time and jumping distributions in order to get two or more regimes for the…

, The Dirac equation have been solved for the q-deformed hyperbolic Scarf potential coupled to a Coulomb-like tensor potential under the spin symmetry. The parametric generalization of the Nikiforov-Uvarov method is used to obtain the energy eigenvalues equation and the…

This paper aimed to monitor the nitrogen compounds and total phosphorous in the Maringá Stream watershed in order to investigate the spatial and temporal variations in the water quality. For this, samplings were collected from seven sites during the period…

Temperature distribution which occurs in pavement and bridge slabs heated for de-icing and snow melting during cold periods is determined by using vertical ground-source heat pump (GSHP) systems with U-tube ground heat exchanger (GHE). The bridge and pavement models (slabs)…

In this paper, a new kind of set called an αγ-open set is introduced and investigated using the γ-operator due to Ogata. Such sets are used for studying new types of mappings, viz. αγ-continuous, α(γ,β)-irresolute, etc. Finally, new separation axioms:…

Higher homotopy of graphs has been defined in several articles. However, the existence of a long exact sequence associated to a pair (G, A) has not been touched at. We treat it here. Applied to the discrete spheres, this lead…

In this paper we introduce the strongly generalized difference sequence spaces of modulus function and is a non-negative four dimensional matrix of complex numbers and (pi(mn)) is a sequence of positive real numbers. We also give natural relationship between strongly…

Authenticated multiple key exchange (AMKE) protocols not only allow participants to warrant multiple session keys within one run of the protocol but also ensure the authenticity of the other party. Many AMKE protocols using bilinear pairings have been proposed. However,…

Uma fornalha, com opção para aquecimento direto e indireto de ar, foi projetada e construída para utilizar, como combustível complementar à lenha, biomassa particulada, resíduo agroindustrial abundante e desperdiçado em boa parte. No intuito de verificar o funcionamento da fornalha,…
