Perchlorate-reducing bacteria from Antarctic marine sediments
(2022-08-08)
Perchlorate is a contaminant that can persist in groundwater and soil, and is frequently detected
in diferent ecosystems at concentrations relevant to human health. This study isolated and characterised
halotolerant ...
Perchlorate Contamination: Sources, Effects, and Technologies for Remediation
(2021-12-10)
Perchlorate is a persistent pollutant, generated via natural and anthropo genic processes, that possesses a high potential for endocrine disruption in humans
and biota. It inhibits iodine fixation, a major reason for ...
A Mathematical Model for the Optimization of the Non-metallic Mining Supply Chain in the Mining District of Calamarí-Sucre (Colombia)
(2020-10-08)
This article presents a mathematical model of the Supply chain of non-metallic mining. The model considers uncertainty scenarios in materials, elements for capacity planning in a multilevel chain and with multiple products. ...
A collaborative EPQ inventory model for a three-echelon supply chain with multiple products considering the effect of marketing effort on demand
(2020-06-01)
This paper presents an inventory model for a three-echelon supply
chain with multiple products and multiple members considering the demand
as an increasing function of the marketing effort. In the proposed inventory
model, ...
Production system in a collaborative supply chain considering deterioration
(2021-06-24)
This research presents a mathematical model for a collaborative planning of the supply chain
involving four echelons (supplier, production plants, distribution, retails, or clients). The
model seeks to maximize profit ...
A new radial basis integration method applied to the boundary element analysis of 2D scalar wave equations
(2022-01-10)
A new integration method named the Radial Basis Integration Method (RBIM) that include the Kriging
Integration Method (KIM) Narváez and Useche (2020) as a particular case and performs boundary only offline precomputations ...
Crack Formation in Chill Block Melt Spinning Solidification Process: A Comparative Analysis Using OpenFOAM
(2022-01-12)
The application of FeSiB family magnetic materials in the electrical or electronic industry has significantly increased owing to the development of amorphous and nanocrystalline metallic glasses using melt spinning and ...
Modos de aprendizaje en los contextos actuales para mejorar el proceso de enseñanza
(2021-09-24)
Learning is a subject of constant concern for all those dedicated to this activity, where there are different paradigmatic approaches. The objective of this work is to assess the different types of learning associated with ...
Spatio-Temporal Filtering for Evoked Potentials Detection
(Springer, 2020)
We propose the new application of the spatio-temporal filtering (STF) method, which is a detection of visual evoked potentials applied to brain-computer interfaces (BCI). STF aims in creating a new, enhanced channel basing ...
A Novel Full Boundary Element Formulation for Transient Analysis of Elastic Membranes Coupled to Acoustics Fluids
(2020)
A full time-direct Boundary Element Formulation for the dynamic analysis of elastic membranes coupled to acoustics fluid is presented. The elastic membranes is modeled using the classical linear elastic pre-stretched ...
