La estructura de la conciencia histórica en clave hemenéutico-ontológica

MIGUEL ANGEL GUZMAN LOPEZ (2019, [Libro])

La estructura de la conciencia histórica en clave hermenéutico-ontológica cuestiona el sentido de la existencia estrechamente ligado a la pregunta por lo propio del ser de cada individuo y de cada pue- blo. Ambas cuestiones relacionadas con lo que hoy se entiende como conciencia histórica. Se trata de un tema de innegable actualidad, apoyado en la formación del autor como historiador y filósofo, con un estilo claro y directo que ofrece una ayuda adicional a todo lector interesado en comprender la estructura de la conciencia histórica.

Wood is a thermoelastic material: when the internal temperature of the wood increases, its modulus of elasticity decreases. This manifestation has an instantaneous and temporary character. That is, if the wood recovers its initial temperature, the modulus of elasticity regains its previous value. This is preferably observed in a temperature range of 0 to 120 ° C.

La madera es un material termoelástico: cuando la temperatura interna de la madera aumenta, su módulo de elasticidad disminuye. Esta manifestación tiene un carácter instantáneo y temporal. Es decir, si la madera recobra su temperatura inicial, el módulo de elasticidad recobra su valor anterior. Este hecho se observa preferentemente en un rango de temperaturas de 0 a 120 °C.

Ontology development for knowledge representation of a metrology lab

RAMON ALBERTO LUQUE MORALES OSCAR HERNANDEZ URIBE ZAIDA ANTONIETA MORA ALVAREZ LEONOR ADRIANA CARDENAS ROBLEDO (2023, [Artículo])

Digital transformation in metrology is impacting the industry, where accurate and fair data are essential to take enterprises to the next level in the digital era. The amount and complexity of information are growing exponentially, and expert knowledge becomes imperative for users to perform measurement tasks and decision-making. This study presents the development of a modular metrological inspection ontology for a metrology laboratory based on the reuse of ontologies related to sensors and units of measurement. Such an ontology considers information about operators and customers (name, telephone number, email) and the linkage to service orders, pieces (length, height, width), measurement strategies (expert notes about measurement procedures and paths), and measuring machines (measuring scope, uncertainty, sensor probe). The proposed solution delivers a digitalized catalog that allows the user to filter records according to the geometrical characteristics of the pieces and recover notes related to measurement procedures and paths for similar cases. The purpose is to promote knowledge sharing and narrow the gap to achieve digital transformation toward Metrology 4.0 in laboratories prepared to offer metrological support.

Appraisal of complementarity of subsurface drip fertigation and conservation agriculture for physiological performance and water economy of maize

C.M. Parihar Hari Sankar Nayak Dipaka Ranjan Sena Renu Pandey Mahesh Gathala ML JAT (2023, [Artículo])

The Indo-Gangetic Plains (IGP) in north-west (NW) India are facing a severe decline in ground water due to prevalent rice-based cropping systems. To combat this issue, conservation agriculture (CA) with an alternative crop/s, such as maize, is being promoted. Recently, surface drip fertigation has also been evaluated as a viable option to address low-nutrient use efficiency and water scarcity problems for cereals. While the individual benefits of CA and sub-surface drip (SSD) irrigation on water economy are well-established, information regarding their combined effect in cereal-based systems is lacking. Therefore, we conducted a two-year field experiment in maize, under an ongoing CA-based maize-wheat system, to evaluate the complementarity of CA with SSD irrigation through two technological interventions–– CA+ (residue retained CA + SSD), PCA+ (partial CA without residue + SSD) – at different N rates (0, 120 and 150 kg N ha-1) in comparison to traditional furrow irrigated (FI) CA and conventional tillage (CT) at 120 kg N ha-1. Our results showed that CA+ had the highest grain yield (8.2 t ha-1), followed by PCA+ (8.1 t ha-1). The grain yield under CA+ at 150 kg N ha-1 was 27% and 30% higher than CA and CT, respectively. Even at the same N level (120 kg N ha-1), CA+ outperformed CA and CT by 16% and 18%, respectively. The physiological performance of maize also revealed that CA+ based plots with 120 kg N ha-1 had 12% and 3% higher photosynthesis rate at knee-high and silking, respectively compared to FI-CA and CT. Overall, compared to the FI-CA and CT, SSD-based CA+ and PCA+ saved 54% irrigation water and increased water productivity (WP) by more than twice. Similarly, a greater number of split N application through fertigation in PCA+ and CA+ increased agronomic nitrogen use efficiency (NUE) and recover efficiency by 8–19% and 14–25%, respectively. Net returns from PCA+ and CA+ at 150 kg N ha-1 were significantly higher by US$ 491 and 456, respectively than the FI-CA and CT treatments. Therefore, CA coupled with SSD provided tangible benefits in terms of yield, irrigation water saving, WP, NUE and profitability. Efforts should be directed towards increasing farmers’ awareness of the benefits of such promising technology for the cultivating food grains and commercial crops such as maize. Concurrently, government support and strict policies are required to enhance the system adaptability.
