Spatial analysis to identify unauthorized municipal solid waste disposal sites in rural areas of southern Mexico.

The management of solid waste in rural areas of developing countries faces significant challenges due to economic constraints and irregular human settlements. These factors often lead to the creation of unauthorized disposal sites, which pose risks to human health, ecosystems and the economy. Remote sensing and geographic information system techniques provide a means to understand the complex issues associated with inadequate municipal solid waste (MSW) disposal.

Technique "without bone tunnels" (Micheli-Kocher) in anterior cruciate ligament reconstruction in growing patients. Surgical details and our experience with 19 cases.

Background: Given the boom in sports in school age, its intensity and the increase in sports in females, we are experiencing a boom in sports injuries characteristic of "adults" in growing patients, the anterior cruciate ligament being an injury with possible serious consequences.

Methods: To show the surgical technique "without bone tunnels" by Micheli-Kocher in anterior cruciate ligament reconstruction in growing patients based on our results in 20 patients.

Results: Since 2017 we have performed the technique "without bone tunnels" by Micheli-Kocher in 30 patients, 20 of whom have been followed up for more than 2 years.

Growth patterns and population dynamics of Chiton articulatus (Mollusca: Polyplacophora): A multi-decade study.

The edible chiton Chiton articulatus is a commercially important mollusk found in the rocky intertidal zones of the Mexican tropical Pacific. Despite the intense harvesting in Acapulco Bay, Mexico, knowledge of its growth patterns is limited, hindering the development of effective management strategies. This study investigated the growth dynamics of C.

A Macroscopic Interpretation of the Correlation between Electrical Percolation and Mechanical Properties of Poly-(Ethylene Vinyl Acetate)/Zn Composites.

Elastic composites were prepared using a procedure involving hot plates and zinc powder that was directly dispersed into an EVA matrix. The correlation between the zinc content and the conductive properties of the material was studied via impedance spectroscopy, the thermal properties of the material were studied via differential calorimetry and the mechanical properties of the composites were studied via tensile strength curves, representing an important advancement in the characterization of this type of composite material. The composites' tensile strength and elongation at break decrease with the addition of filler since zinc particles act as stress-concentrating centres, while the composites' hardness and Young's modulus increase because of an increase in the stiffness of the material.
