An Effective Power Dispatch of Photovoltaic Generators in DC Networks via the Antlion Optimizer
(2023-01-27)
This paper studies the problem regarding the optimal power dispatch of photovoltaic (PV) distributed generators (DGs) in Direct Current (DC) grid-connected and standalone networks. The mathematical model employed considers ...
An Efficient EMS for BESS in Monopolar DC Networks with High Penetration of Renewable Generation: A Convex Approximation
(2023-01-26)
This research presents an efficient energy management system (EMS) for battery energy storage systems (BESS) connected to monopolar DC distribution networks which considers a high penetration of photovoltaic generation. ...
Suicide risk and media consumption in the COVID-19 pandemic in Colombia
(2023-01-19)
The media can play an important role in suicide prevention and mental health care, especially in a country like Colombia, affected by an internal armed conflict, and with worrying cases of suicide that increased during the ...
Application of Pyrolysis for the Evaluation of Organic Compounds in Medical Plastic Waste Generated in the City of Cartagena-Colombia Applying TG-GC/MS
(2023-03-11)
In this study, the thermal degradation and pyrolysis of hospital plastic waste consisting of polyethylene (PE), polystyrene (PS), and polypropylene (PP) were investigated using TG-GC/MS. The identified molecules with the ...
A new Valorization Route of Petrochemical Wastewater: Recovery of Phenolic Derivatives and their Subsequent Application in a PP Matrix for the Improvement of their Durability in Multiple Applications
(2023-02-16)
Wastewater from industrial processes contains different compounds that can be of great use to improve its circularity. The potential of wastewater can be exploited by applying extraction techniques to obtain compounds of ...
Quantification of the Synthetic Phenolic Antioxidant Cyanox 1790 in Bottled Water with SPE-HPLC/MS/MS and Determination of the Impact of the Use of Recycled Packaging on Its Generation
(2023-02-28)
One route of exposure to SPAs is through bottled water since the polymers used to make
plastic bottles contain these SPAs, which migrate from the plastic to the water. Solid-phase extraction
(SPE), HPLC-MS, FTIR, and DSC ...
Theoretical–Experimental Study of the Action of Trace Amounts of Formaldehyde, Propionaldehyde, and Butyraldehyde as Inhibitors of the Ziegler–Natta Catalyst and the Synthesis of an Ethylene–Propylene Copolymer
(2023-02-22)
The copolymer synthesis process can be affected by failures in the production process or by contaminating compounds such as ketones, thiols, and gases, among others. These impurities act as an inhibiting agent of the ...
Two-dimensional simulation of emptying manoeuvres in water pipelines with admitted air
(2023-05-09)
This study examines the impact of sub-atmospheric pressures in water pipelines during emptying manoeuvres with air admitted. Previous research has looked at this issue but has not studied it in detail. This research presents ...
Studies of Endocrine Disruptors: Nonylphenol and Isomers in Biological Models
(2023-04-14)
Abstract
Certain emerging pollutants are among the most widely used chemicals globally, causing widespread concern in relation to their use in products devoted to cleaniness and asepsis. Nonylphenol ethoxylate (NPEOn) is ...
The DESI Bright Galaxy Survey: Final Target Selection, Design, and Validation
(2023-05-26)
Over the next 5 yr, the Dark Energy Spectroscopic Instrument (DESI) will use 10 spectrographs with 5000 fibers on the 4 m Mayall Telescope at Kitt Peak National Observatory to conduct the first Stage IV dark energy galaxy ...
