DEGRADATION OF PUBLIC SQUARE AND THE RISK FACTORS FOR THE POPULATION: EXAMPLES FROM THE CITY OF NATAL/RN
(Univ Federal Fluminense, 2017-05-01)
The conditions of degradation in which are some public square of the city fall directly on the fall of his quality and the loss of their functions, and can pose risks to their users. In this sense, the goal is to check ...
Comment on: Exact solution of theinverse-square-root potential V(r) = −α/√r
(Academic Press Inc Elsevier Science, 2017-04)
We study the connection between the solutions of the Schrödinger equation with an inverse square-root potential in three and one dimension. In particular we show that an approximate analytical expression for the eigenvalues ...
Frustating use of the Laplace transform for the quantum states of a particle in a box
(Sociedade Brasileira de Física, 2020-05-29)
In a recent paper diffused in the literature, the quantum problem of a particle in a infinite square well potential was claimed to be solved via Laplace transform. Surprisingly, the correct solutions were found for an ...
Influence surfaces by boundary element/least square methods coupling
(2016-04-01)
This work presents a new application for calculating the influence surfaces of transverse displacements, directional derivatives and bending moments for generic bridge decks. A plate bending boundary element method formulation ...
Supersymmetric Majorana quantum cosmologies
(American Physical Society, 2015)
The Einstein equations for an isotropic and homogeneous Friedmann-Robertson-Walker universe in the presence of a quintessence scalar field are shown to be described in a compact way, formally identical to the dynamics of ...
