New idea for the topological index evaluation and treatise multiple regression with three independent variables. Saturated hydrocarbons used like a model
(SOCIEDAD CHILENA DE QUIMICA, 2006-03)
In QSRR discipline an easy novel to used parameter was designed (Vc) for evaluated classical topological index (W, (1)chi, Z, MTI) and two new generation ones (Xu, (1)chi(h)). Regression between Vc and (1)chi(h) presented ...
Optimization of the implicit exponent in the algorithm corresponding to the corrected three-dimensional valence connectivity index L(q). Application to saturated hydrocarbons
(SOCIEDAD CHILENA DE QUIMICA, 2002-03)
In this work one demostrates that the use of the algorithm corresponding to the corrected three-dimensional valence connectivity index [Lambda(q)], used at a value of optimal exponent, produces a maximun value for the ...
A new vector for the structure the H. P. Schultz topological index.
(SOCIEDAD CHILENA DE QUIMICA, 2000-12)
A new vector (V-c) is proposal for structure the topological index of H. P. Schultz (2-MTI).
This vector contain elements that correspond to the electron charge density soported on the carbon atoms of the molecule and ...
Encefalopatía tóxica por isopropanol. Sobre-exposición accidental a gas propano
(2016)
Liquefied hydrocarbon gas, such as propane is considered safe. However there are reports that voluntary exposure to liquefied gas at least could originate hallucinatory states. We report a 20 years old woman who was found ...
Modelación de la viscosidad dinámica de fluidos newtonianos a partir de la teoría de Eyring y la energía libre de Helmholtz residual
(Fondo Editorial EIA - Universidad EIA, 2022-06-01)
En este trabajo se modela la viscosidad dinámica de fluidos newtonianos a partir de la teoría de Eyring junto con la energía libre de Helmholtz residual. Para la estimación de esta energía se utiliza una versión modificada ...
Petrophysical properties of the Lower Cretaceous formations in the Shaikhan oilfield, northern Iraq
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Geociencia, 2018-01-01)
The current study represents an evaluation of the petrophysical properties in the well Shaikhan-8 for the Garagu, Sarmord and Qamchuqa formations in Shaikhan oilfield, Duhok basin, northern Iraq. The petrophysical evaluation ...
