Educación del diseño en el futuro. Híbrida, sustentable y especializada

Rubén Sahagún Angulo (2023, [Capítulo de libro])

Las disciplinas del Diseño, como otras, sobre todo en escuelas de las grandes ciudades, deberán ofertar sus carreras a distancia para reducir significativamente los problemas asociados a la movilidad y la segregación socioespacial de sus estudiantes. También deberán revisar sus planes de estudio para verter los temas de la sustentabilidad de manera transversal. Finalmente, las especialidades serán una vía para que los profesionales del Diseño regresen a la Universidad a prepararse, en lugar de ofrecer únicamente maestrías y doctorados que, en su mayoría, son cursados por profesores o investigadores.

Design disciplines, like others, especially in schools in large cities, should offer their degrees online to significantly reduce the problems associated with mobility and socio-spatial segregation of their students. Also, they should review their study plans to cover sustainability issues in a transversal way. Finally, the specialties will be a way for design professionals to return to the University to prepare, instead of only offering master’s and doctoral degrees, which are mostly taken by professors or researchers.

Enhancing maize yield in a conservation agriculture-based maize (Zea mays)- wheat (Triticum aestivum) system through efficient nitrogen management

C.M. Parihar Hari Sankar Nayak Dipaka Ranjan Sena Shankar Lal Jat Mahesh Gathala Upendra Singh (2023, [Artículo])

This study evaluated the impact of contrasting tillage and nitrogen management options on the growth, yield attributes, and yield of maize (Zea mays L.) in a conservation agriculture (CA)-based maize-wheat (Triticum aestivum L.) system. The field experiment was conducted during the rainy (kharif) seasons of 2020 and 2021 at the research farm of ICAR-Indian Agricultural Research Institute (IARI), New Delhi. The experiment was conducted in a split plot design with three tillage practices [conventional tillage with residue (CT), zero tillage with residue (ZT) and permanent beds with residue (PB)] as main plot treatments and in sub-plots five nitrogen management options [Control (without N fertilization), recommended dose of N @150 kg N/ha, Green Seeker-GS based application of split applied N, N applied as basal through urea super granules-USG + GS based application and 100% basal application of slow release fertilizer (SRF) @150 kg N/ha] with three replications. Results showed that both tillage and nitrogen management options had a significant impact on maize growth, yield attributes, and yield in both seasons. However, time to anthesis and physiological maturity were not significantly affected. Yield attributes were highest in the permanent beds and zero tillage plots, with similar numbers of grains per cob (486.1 and 468.6). The highest leaf area index (LAI) at 60 DAP was observed in PB (5.79), followed by ZT(5.68) and the lowest was recorded in CT (5.25) plots. The highest grain yield (2-year mean basis) was recorded with permanent beds plots (5516 kg/ha), while the lowest

was observed with conventional tillage (4931 kg/ha). Therefore, the study highlights the importance of CA practices for improving maize growth and yield, and suggests that farmers can achieve better results through the adoption of CA-based permanent beds and use of USG as nitrogen management option.

Variability of Microcirculation Detected by Blood Pulsation Imaging

Alexei Kamshilin (2013, [Artículo])

The non-invasive assessment of blood flow is invaluable for the diagnostic and monitoring treatment of numerous vascular and neurological diseases. We developed a non-invasive and non-contact method of blood pulsation imaging capable of visualizing and monitoring of the two-dimensional distribution of two key parameters of peripheral blood flow: the blood pulsation amplitude and blood pulsation phase. The method is based on the photoplethysmographic imaging in the reflection mode. In contrast with previous imaging systems we use new algorithm for data processing which allows two dimensional mapping of blood pulsations in large object's areas after every cardiac cycle. In our study we carried out the occlusion test of the arm and found (i) the extensive variability of 2D-distribution of blood pulsation amplitude from one cardiac cycle to another, and (ii) existence of the adjacent spots to which the blood is asynchronously supplied. These observations show that the method can be used for studying of the multicomponent regulation of peripheral blood circulation. The proposed technique is technologically simple and cost-effective, which makes it applicable for monitoring the peripheral microcirculation in clinical settings for example, in diagnostics or testing the efficiency of new medicines. © 2013 Kamshilin et al.

El sistema de ecuaciones de Saint-Venant y Richards del riego por gravedad: 2. Acoplamiento numérico para la fase de avance en el riego por melgas

HEBER ELEAZAR SAUCEDO ROJAS CARLOS FUENTES RUIZ MANUEL ZAVALA TREJO (2005, [Artículo])

Se presenta una solución numérica monótona para el acoplamiento interno de las ecuaciones de Saint-Venant y Richards en el riego por melgas. La solución de las ecuaciones de Saint-Venant se aproxima utilizando un esquema lagrangiano en diferencias finitas; mientras que para la ecuación de Richards se utilizan elementos finitos para la integración en el espacio y diferencias finitas implícitas para la integración en el tiempo. Se muestra que una discretización de la ecuación de momentum, basada en aproximaciones de las derivadas y los coeficientes mediante ponderaciones en tiempo y espacio, puede generar cambios de monotonía en la vecindad de la cabecera de la melga; asimismo, se muestra que dicha situación no se presenta si se utiliza una discretización basada en: a) las derivadas en el espacio y la pendiente de fricción en una celda de cálculo se aproximan adelante en el tiempo; b) las derivadas en el tiempo se aproximan utilizando una forma ponderada; y c) los coeficientes son calculados en el tiempo anterior.

Chemically modified nanoparticles for enhanced antioxidant and antimicrobial properties with cinnamon essential oil

Aaron Azael Lopez Cano VERONICA MARTINEZ AGUILAR Mariana Peña-Juárez Ricardo López Esparza Enrique Delgado Alvarado Emmanuel Gutierrez MAYRA DEL ANGEL MONROY Elias Perez Agustin L. Herrera-May JOSE AMIR GONZALEZ CALDERON (2023, [Artículo])

We explored the potential of different nanoparticles (TiO2, CaCO3, and Al2O3), considering their pure form and modified with cinnamon essential oil (CEO). These materials were characterized using various techniques, including FTIR spectroscopy, XRD analysis, TGA, and SEM. The interaction between CEO and nanoparticles changed depending on the nanoparticle type. Al2O3 nanoparticles exhibited the strongest interaction with CEO, increasing their antioxidant capacity by around 40% and their transfer of antimicrobial properties, particularly against Gram-negative bacteria. In contrast, TiO2 and CaCO3 nanoparticles showed limited interaction with CEO, resulting in lower antioxidant capacity and antimicrobial activity. Incorporating pure and CEO-modified nanoparticles into polylactic acid (PLA) films improved their mechanical and thermal properties, which are suitable for applications requiring greater strength. This research highlights the potential of metal oxide nanoparticles to enhance the antimicrobial and antioxidant capabilities of polymers. In addition, incorporating cinnamon essential oil can increase the antioxidant and antimicrobial effectiveness of the metal oxide nanoparticles and improve the mechanical and thermal properties of PLA films. Thus, these PLA films exhibit favorable characteristics for active packaging applications.

Approaches in Polymeric Nanoparticles for Vaginal Drug Delivery: A Review of the State of the Art

GERARDO LEYVA GOMEZ ELIZABETH PIÑON SEGUNDO NESTOR MENDOZA MUÑOZ MARIA DE LA LUZ ZAMBRANO ZARAGOZA SUSANA ELISA MENDOZA ELVIRA DAVID QUINTANAR GUERRERO (2018, [Artículo])

The vagina is a region of administration with a high contact surface to obtain local or systemic effects. This anatomical area represents special interest for government health systems for different sexually transmitted infections. However, the chemical changes of the vagina, as well as its abundant mucus in continuous exchange, act as a barrier and a challenge for the development of new drugs. For these purposes, the development of new pharmaceutical forms based on nanoparticles has been shown to offer various advantages, such as bioadhesion, easy penetration of the mucosa, and controlled release, in addition to decreasing the adverse effects of conventional pharmaceutical forms. In order to obtain nanoparticles for vaginal administration, the use of polymers of natural and synthetic origin including biodegradable and non-biodegradable systems have gained great interest both in nanospheres and in nanocapsules. The main aim of this review is to provide an overview of the development of nanotechnology for vaginal drug release, analyzing the different compositions of polymeric nanoparticles, and emphasizing new trends in each of the sections presented. At the end of this review, a section analyzes the properties of the vehicles employed for the administration of nanoparticles and discusses how to take advantage of the properties that they offer. This review aims to be a reference guide for new formulators interested in the vaginal route.
