Cuantificación voltamétrica de carbofurano en papa (Solanum tuberosum L., Solanaceae)

Ciencia y Tecnología Agropecuaria, 2017
El exceso en la aplicación de plaguicidas puede generar acumulaciones en los tubérculos de papa que sobrepasen el límite máximo residual (LMR) presentado por el Codex Alimentarius, lo cual representa riesgos para la salud de los consumidores.

Electrochemical Biosensor for Sensitive Quantification of Glyphosate in Maize Kernels

Electroanalysis, Volume 31, Issue 5, Page 927-935, May 2019., 2019
Abstract A graphite‐epoxy electrode (GE) modified with multiwalled carbon nanotubes (MWCNTs) and horseradish peroxidase (GE/MWCNTs‐HRP) was used to build a glyphosate biosensor whose performance in aqueous solutions depends on the enzyme activity. For the biosensor preparation, MWCNTs were deposited onto the GE surface by electrophoresis using an ...

Seed Thermal Response, and Morphological and Biochemical Plasticity in Wigandia urens as Indicators of Its Utility for Elevational and Latitudinal Assisted Migration

Ecology and Evolution, Volume 15, Issue 12, December 2025.
To identify the phenotypic plasticity in germination traits related to the tolerance to changes in temperature resulting from CC and improve the successful of plant cover recovery in elevational and latitudinal gradients, we assessed the amplitude and variability of phenotypic plasticity in the seed response of W.

Composite Materials Based on Henequen Fiber as a Thermal Barrier in the Automotive Sector

Advances in Materials Science and Engineering, Volume 2019, Issue 1, 2019., 2019
Currently, the automotive industry has made great advances in the incorporation of materials such as carbon fiber in high‐performance cars. One of the main problems of these vehicles is warming, which is generated inside due to the heat transfer produced by solar radiation falling on the car, mainly on the roof.

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

Advances 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.

Evaluation of Yarrowia lipolytica Oil for Biodiesel Production: Land Use Oil Yield, Carbon, and Energy Balance

Journal of Lipids, Volume 2018, Issue 1, 2018., 2018
Oils from yeasts have emerged as a suitable alternative raw material to produce biodiesel, due to their similar composition to common raw materials such as vegetable oils. Additionally, they have the advantage of not competing with human or animal feed, and, furthermore, they do not compete for arable land. In this work, a carbon and energy balance was
