A Bayesian Approach for Estimating the Thinning Corrosion Rate of Steel Heat Exchanger in Hydrodesulfurization Plants

open access: yesAdvances in Materials Science and Engineering, Volume 2018, Issue 1, 2018., 2018
Fuel consumption has been increasing in recent years, especially that of diesel and jet fuel. For this reason, the necessity to build new plants to reduce their sulfur content has arisen. Sometimes, just revamping existing plants is feasible, but determining which pieces of equipment are in the appropriate condition to be reused is also necessary.

Los acueductos romanos

open access: yesInformes de la Construcción, 1968
El tema del puente romano se enriquece al considerar las obras de fábrica que en las conducciones de agua (ductionis aquae) soportan el canal sobre el terreno mediante arcadas (arcuatiónibus), obras que denominamos acueductos, tomando el sentido reestrícto de la palabra, que también puede aplicarse a toda la conducción en sentido general.

Neural Models for Imputation of Missing Ozone Data in Air‐Quality Datasets

open access: yesComplexity, Volume 2018, Issue 1, 2018., 2018
Ozone is one of the pollutants with most negative effects on human health and in general on the biosphere. Many data‐acquisition networks collect data about ozone values in both urban and background areas. Usually, these data are incomplete or corrupt and the imputation of the missing values is a priority in order to obtain complete datasets, solving ...

Predicted 3D Model of the Rabies Virus Glycoprotein Trimer

open access: yesBioMed Research International, Volume 2016, Issue 1, 2016., 2016
The RABVG ectodomain is a homotrimer, and trimers are often called spikes. They are responsible for the attachment of the virus through the interaction with nicotinic acetylcholine receptors, neural cell adhesion molecule (NCAM), and the p75 neurotrophin receptor (p75NTR). This makes them relevant in viral pathogenesis.

Biologically Active and Antimicrobial Peptides from Plants

open access: yesBioMed Research International, Volume 2015, Issue 1, 2015., 2015
Bioactive peptides are part of an innate response elicited by most living forms. In plants, they are produced ubiquitously in roots, seeds, flowers, stems, and leaves, highlighting their physiological importance. While most of the bioactive peptides produced in plants possess microbicide properties, there is evidence that they are also involved in ...
