Magnetostatic model for magnetic particle aggregates with cylindrical shapes
(Sociedad Mexicana de Física, A. C., 2023)Building micro and macro sized structures using compacted magnetic nanoparticles is a widely used approach that has proven a great potential as the basis for novel materials made by design. These materials are made by ... -
Bidimensional Deterministic Model for Diffusion and Settling of Particles
(MDPI, 2023)In this paper, we present a study of the diffusion properties of a deterministic model for settling particles in two displacement dimensions. The particularities of the novel deterministic model include the generation of ... -
The Ahualulco Volcanic Complex: Geochemistry and temporal evolution of Oligocene felsic volcanism, in the east of the Mesa Central, San Luis Potosí, Mexico [El complejo volcánico de Ahualulco: geoquímica y evolución temporal del vulcanismo félsico del Oligoceno, en el oriente de la Mesa Central, San Luis Potosí, México]
(Instituto de Geociencias, UNAM, 2023)The Ahualulco Volcanic Complex (AVC), in the southern region of the Mesa Central of Mexico, consists of a set of Cenozoic volcanic rocks, which includes andesites. The AVC was emplaced in the middle Eocene, followed by ... -
Phenolic Compounds in Agro-Industrial Waste of Mango Fruit: Impact on Health and Prebiotic Effect – a Review
(Institute of Animal Reproduction and Food Research of the Polish Academy of Sciences in Olsztyn, 2023)The fruit processing industry generates huge amounts of waste annually, causing severe environmental problems. Mango processing produces around 20 million tons of wastes from the non-consumed fraction, mainly peels and ... -
Graphene–Cu Nanocomposites Induce Tolerance against Fusarium oxysporum, Increase Antioxidant Activity, and Decrease Stress in Tomato Plants
(MDPI, 2023)The tomato crop is susceptible to various types of stress, both biotic and abiotic, which affect the morphology, physiology, biochemistry, and genetic regulation of plants. Among the biotic factors, is the phytopathogen ... -
Expression of EPL1 from Trichoderma atroviride in Arabidopsis Confers Resistance to Bacterial and Fungal Pathogens
(MDPI, 2023)During plant interaction with beneficial microorganisms, fungi secrete a battery of elicitors that trigger plant defenses against pathogenic microorganisms. Among the elicitor molecules secreted by Trichoderma are ... -
Riccati equations of opposite torsions from the Lie-Darboux method for spatial curves and possible applications
(IOP, 2024)A novel formulation of the Lie-Darboux method of obtaining the Riccati equations for the spatial curves in Euclidean three-dimensional space is presented. It leads to two Riccati equations that differ by the sign of torsion. ... -
