Aging is a multifactorial phenomenon that involves the different levels of biological organization, leading to the old age frailty and dysfunction, which eventually culminates in pathologies and death. The brain is a very susceptible tissue due to its high oxygenic need and low antioxidant capacity generating neurodegenerative diseases. Nrf2 is...
Seed priming is a pregerminative technique for improving seed germination and vigor, it involves imbibition of seeds in water under controlled conditions to initiate early events of germination followed by drying the seed back to its initial moisture content, in order to have a control on germination. Beaucarnea gracilis (Nolinaceae)...
In this work we developed the theory to characterize the structure of optimal sequential tests for experiments, introducing a random horizon, unlike an infinity horizon as in the classical theory. We analyzed the optimal sequential tests found with random horizon in terms of probability ratio and when a particular case...
Los granos de polen en Mimosa, se asocian en: tétrades, bitétrades y políades de 12-16 granos, que varían de tamaño y morfología, características relacionadas con la forma y la profundidad del estigma. El objetivo de este trabajo es mostrar la relación entre la forma y tamaño de polen y el...
Los modelos de masa-consistente nos permiten aproximar campos de viento 3D sobre una región de estudio, a partir de la componente horizontal u I . Este modelo se basa en la ecuación de continuidad para un dominio Ω con paredes artificiales. En este trabajo se presenta la formulación del problema...
