En la indagación se estudió una empresa de servicios de limpieza, la cual, debido al inapropiado cumplimiento de las normas tributarias, cometió diversas infracciones tributarias, las cuales, fueron detectadas y sancionadas ...
Solubility of hydrogen sulfide in ionic liquids for gas removal processes using artificial neural networks.
(2016)
Artificial neural networks have been used for the correlation and prediction of solubility data of hydrogen sulfide in ionic liquids. The solubility of hydrogen sulfide is highly variable for different types of ionic liquids ...
Predictions of fluidities of amines by molecular simulations: TraPPE-EH vs. OPLS-AA
(Elsevier B.V., 2018-05-25)
Amines have several important industrial properties and commercial applications, such as gas sweetening and carbon capture; and the synthesis of: tranquilizers, decongestants, and azo dyes. For the design of many engineering ...
Application of switchable hydrophobicity solvents for extraction of emerging contaminants in wastewater samples
(MDPI, 2020)
In the present work, the effectiveness of switchable hydrophobicity solvents (SHSs) as extraction solvent (N,N-Dimethylcyclohexylamine (DMCA), N,N-Diethylethanamine (TEA), and N,N-Benzyldimethylamine (DMBA)) for a variety ...
Relative liquidity and future volatility
(Elsevier, 2015)
The main contribution of this paper is to identify the strong predictive power of the relative, rather than the absolute, volume of orders over volatility. To this end, we propose a new measure, relative liquidity, which ...

Dispersive liquid–liquid microextraction and gas chromatography accurate mass spectrometry for extraction and non-targeted profiling of volatile and semi-volatile compounds in grape marc distillates
(Elsevier Science, 2018-04)
The suitability of dispersive liquid–liquid microextraction (DLLME) and gas chromatography accurate mass spectrometry (GC–MS), based on a time-of-flight (TOF) MS analyzer and using electron ionization (EI), for the ...
Determination of beta-artemether and its main metabolite dihydroartemisinin in plasma employing liquid-phase microextraction prior to liquid chromatographic-tandem mass spectrometric analysis
(ELSEVIER SCIENCE BV, 2010)
A method for the determination of artemether (ART) and its main metabolite dihydroartemisinin (DHA) in plasma employing liquid-phase microextraction (LPME) for sample preparation prior to liquid chromatography-tandem mass ...
