The fourth industrial revolution in education after covid-19

The global pandemic caused by COVID-19 has meant a great change in education since teachers worldwide have had to face the problem of having to undertake online training without adequate preparation or means. In view of this, the fourth industrial revolution, has begun to establish itself strongly as pedagogical support and there are already many governments that are pursuing changes in educational policies that insert a digital education that fragments education and prepares students for the jobs in the 21st century so this revolution is not only imminent but necessary

Efecto de diferentes ambientes y empaques sobre la viabilidad de semillas de maracuyá (Passiflora edulis var. Flavicarpa Degener)

The present research was done during the second semester of 2004 in order to evaluate viability of passionfruit seed stored in different containers and temperature. A factorial (2X3) complete randomized design with four replicates for each treatment was used, factor A was container: plastic bag (PB) and hard plastic (HP); while factor B stands for cold room (CR, 5±1°C and 38±2% RH), freezer (F, 5±2 °C and 78% RH) and room temperature (RT, 24°C and 32.2°C). The evaluated variables were germination (%), vigor (%) and seed humidity (%) at 0, 30 60, 90 and 120 days after storage (DAS). The highest germination and vigor percentages were observed at 60 and 90 DAS using PB stored in CR and F. These treatment combination kept seed quality without any sign of deterioration. At 120 DAS, germination decreased in all treatments, however, percentage was still above initial germination level (73.5%).El maracuyá es uno de los frutales más importantes del departamento de Córdoba, donde el área cultivada se ha incrementado considerablemente. La calidad de la semilla, para el establecimiento de nuevos cultivos, juega un papel relevante en este sistema de producción, por tal razón se procedió a evaluar la viabilidad de las semillas de maracuyá (Passiflora edulis var. flavicarpa Degener) almacenada en diferentes empaques y ambientes a través del tiempo. Se utilizó un diseñó completamente aleatorizado con estructura factorial 2x3 y cuatro repeticiones. El factor A correspondió a dos tipos de empaques: bolsa plástica y tarro plástico, y el factor B estuvo constituido por tres ambientes: cuarto frío (5±1ºC y H.R. del 38±2%), nevera (5±2 ºC y H.R. del 78%) y condiciones ambientales locales (24°C y 32.2°C, con media de 27.9°C y H.R. del 80%). Se evaluaron las variables germinación, vigor y humedad, en porcentaje, a los 30, 60, 90 y 120 días después de almacenadas las semillas. La mejor respuesta en las variables germinación y vigor se obtuvo en los ambientes refrigerados utilizando bolsa plástica, con valores de germinación cercanos a 100%, superiores a los obtenidos a partir de semillas recién extraídas del fruto. Con esta combinación se mantuvo la calidad de la semilla, sin percibirse indicios de deterioro en el tiempo transcurrido. A los 120 días de almacenamiento, el porcentaje de germinación disminuyó en todos los tratamientos, pero fue superior al obtenido a partir de semillas recién extraídas del fruto, es decir por encima de 73.5%

Variables Influencing the Accuracy of 3D Modeling of Existing Roads Using Consumer Cameras in Aerial Photogrammetry

Point cloud (PC) generation from photogrammetry–remotely piloted aircraft systems (RPAS) at high spatial and temporal resolution and accuracy is of increasing importance for many applications. For several years, photogrammetry–RPAS has been used to recover civil engineering works such as digital elevation models (DEMs), triangle irregular networks (TINs), contour levels, orthophotographs, etc. This study analyzes the influence of variables involved in the accuracy of PC generation over asphalt shapes and determines the most influential variable based on the development of an artificial neural network (ANN) with patterns identified in the test flights. The input variables were those involved, and output was the three-dimension root mean square error (3D-RMSE) of the PC in each ground control point (GCP). The result of the study shows that the most influential variable over PC accuracy is the modulation transfer function 50 (MTF50). In addition, the study obtained an average 3D-RMSE of 1 cm. The results can be used by the scientific and civil engineering communities to consider MTF50 variables in obtaining images from RPAS cameras and to predict the accuracy of a PC over asphalt based on the ANN developed. Also, this ANN could be the beginning of a large database containing patterns from several cameras and lenses in the world market.The article processing charge (APC) was funded by the Research Group “Ingeniería Cartográfica” (Grant No. PAIDI-TEP-164 from the Regional Government of Andalucía) from the University of Jaén

Excavaciones en el conjunto megalítico de la Peña Oviedo (Camaleño, Cantabria)

La excavación del conjunto megalítico de la Peña Oviedo, pretende ser el inicio de un estudio más amplio que aborde de manera global el fenómeno megalítico en las cue.ncas altas de los ríos Deva y Nansa. El total desconocimiento que se tenía hasta esta década, no ya del fenómeno megalítico, sino incluso de su existencia en estos valles montañosos del Occidente de Cantabria hace necesario un estudio que ponga de manifiesto sus características y las relaciones con las áreas vecinas.The excavation of the megalithic complex of the Peña Oviedo, pretends to be the beginning of a larger study that approaches the megalithic phenomenon in the global River basins of the Deva and Nansa rivers. The total lack of knowledge of the megalithic phenomenon, but not even of its existence in these mountain valleys of western Cantabria, requires a study that reveals its characteristics and relations with neighboring areas

Architecture of the ESCPE-1 membrane coat

Recycling of membrane proteins enables the reuse of receptors, ion channels and transporters. A key component of the recycling machinery is the endosomal sorting complex for promoting exit 1 (ESCPE-1), which rescues transmembrane proteins from the endolysosomal pathway for transport to the trans-Golgi network and the plasma membrane. This rescue entails the formation of recycling tubules through ESCPE-1 recruitment, cargo capture, coat assembly and membrane sculpting by mechanisms that remain largely unknown. Herein, we show that ESCPE-1 has a single-layer coat organization and suggest how synergistic interactions between ESCPE-1 protomers, phosphoinositides and cargo molecules result in a global arrangement of amphipathic helices to drive tubule formation. Our results thus define a key process of tubule-based endosomal sorting.This work was funded by MCIN/AEI/10.13039/501100011033 (PID2020- 119132GB-I00, CEX2021-001136-S) (to A.H.), the Intramural Program of NICHD, NIH (ZIA HD001607 to J.S.B.), the Swiss National Science Foundation grant 205321 179041 (to D.C.-D.), the Human Frontiers Science Program grant RGP0017/2020 (to D.C.-D.) and the PID2021- 127309NB-I00 funded by AEI/10.13039/501100011033/ FEDER, UE (to D.C.-D.).

Book Review: \u3ci\u3eSuperstitious Regimes\u3c/i\u3e by Rebecca Nedostup

Superstitious Regimes is an interdisciplinary work that sheds new light on the interaction between the state-body and the religion-body in early twentieth-century China, with a focus on the Nanjing Decade (1927-1937). Nedostup develops her analysis from both a diachronic and synchronic perspective. The author underlines shifts and continuities between a few historical periods: Sun Yat-sen’s time, the early years of the Nanjing Decade, the late years of the Nanjing Decade, and the post-Nanjing Decade. Nedostup’s interdisciplinary study is of interest for a large readership: students and scholars of Chinese studies, Chinese politics, Chinese religions, and Chinese history would all benefit from reading this book, both for its contents and for the research methodologies that the author adopted
