Synthesis, characterization and applications of carbon-based calcium catalysts deriving from avocado seeds for biodiesel production

This article thoroughly investigates and analyzes the evolution, design, operation, and future potential of modular reactors in the field of nuclear energy. It addresses the key advantages of these systems, their inherent safety features, as well as the challenges and opportunities they present. Furthermore, the relevance of modular reactors in the context of transitioning towards cleaner and more sustainable energy sources is discussed. The indicator related to the land use intensity in small modular reactors is addressed. Through an interdisciplinary approach, this article aims to shed light on the current state of modular reactor technology and provide an informed perspective on their role in the future energy generation. Results show that land use intensity index is between 0.07-0.08 m2 /MWhy. SMRs have advantages such as safety, mass production and easy transportation; which enables their deployment in remote or isolated areas. Also, this technology can play a key role in the transition to cleaner and sustainable energy production, making them accessible for countries with limited budgets. However, SMRs are in a nascent state and more research is required to address aspects such as environmental impact, human risk, generation efficiency and integration with other energy sources.

This assessment report establishes the value of the Hindu Kush Himalaya (HKH) for the 240 million hill and mountain people across the eight countries sharing the region, for the 1.65 billion people in the river basins downstream, and ultimately for the world. Yet, the region and its people face a range of old and new challenges moving forward, with climate change, globalization, movement of people, conflict and environmental degradation. At the same time, we also see incredible potential to meet these challenges in a sustainable manner

Lipids extraction from sewage sludge through Green-biobased solvents

ABSTRACT | This study aimed to evaluate the effect of partial to total replacement of fish meal (FM) and fish oil (FO) from diets formulated for the yellowtail (Seriola dorsalis) using poultry by-product meal (PBM) as the main protein source, beef tallow as the main fat source, and supplemented with microalgae oil from Schizochytrium sp. Four experimental diets were formulated to be isoproteic (45.0 % crude protein) and isolipidic (12.0 % crude fat), based on the yellowtail nutritional requirements. Cholesterol was added to compensate its content in the FO. Lysine and methionine were also added to compensate its lower amount in the PBM. DHA-Nature��� was additional incorporated to reach similar levels of DHA than those present in FM and FO. One hundred and eighty S. dorsalis juveniles (14.54 g �� 0.19 g, mean �� SE) were randomly distributed into 12 tanks with 500 L each, connected into a recirculation system. After 48 days experimentation procedure, no significant differences were observed in performance. It is concluded that PBM can efficiently replace FM and FO in diets for Seriola dorsalis without any negative impact, where the fatty acid combination contained in the total replacement favored the use of fat as an energy source if DHA is enriched. However, it will be interesting to study the gene expression within the growth axis to fully comprehend the role of somatic growth vs. growth in length. RESUMEN | Este estudio tuvo como objetivo evaluar el efecto de la sustituci��n parcial a total de la harina de pescado (FM) y el aceite de pescado (FO) de las dietas formuladas para el jurel de Castilla (Seriola dorsalis), utilizando harina de subproductos av��colas (PBM) como la principal fuente de prote��na, y sebo de res como principal fuente de grasa suplementado con aceite de microalgas de Schizochytrium sp. Se formularon cuatro dietas experimentales isoproteicas (45,0% de prote��na cruda) e isolip��dicas (12.0% de grasa cruda), con base en los requerimientos nutricionales del jurel de Castilla. Se a��adi�� colesterol para compensar su contenido en el FO. Tambi��n se agregaron lisina y metionina para compensar su falta en el PBM. Se incorpor�� adicionalmente la harina de microalgas para alcanzar niveles similares de DHA que los presentes en FM y FO. Los juveniles de S. dorsalis se distribuyeron aleatoriamente (180 con 14,54 g �� 0.19 g, media �� SE) en 12 tanques de 500 L cada uno. Los cuales estaban conectados a un sistema de recirculaci��n. Despu��s de 48 d��as de experimentaci��n, no se observaron diferencias significativas en el rendimiento. Se concluye que el PBM puede reemplazar eficientemente a FM y FO en dietas para S. dorsalis sin ning��n impacto negativo, donde la combinaci��n de ��cidos grasos contenida en el reemplazo total favoreci�� el uso de grasas como fuente de energ��a si se enriquece con DHA. Sin embargo, ser�� interesante estudiar la expresi��n g��nica dentro del eje de crecimiento para comprender mejor el papel del crecimiento en peso en comparaci��n al crecimiento en longitud.

The Ibero-American Congress of Smart Cities (ICSC-CITIES), a forum for Smart Cities discussion, presents this book of articles from its sixth conference, held in presential and virtual mode format in Ciudad de México and Cuernavaca, México, from November 13-17, 2023. A Smart City is a framework composed mainly of Internet of Things systems and Information and Communication Technologies integrated to develop, implement, and promote sustainable development practices and face the challenges of urbanization. ICSC-CITIES aims to create synergies among different research groups to promote the development of Smart Cities and contribute to their knowledge and integration in different scenarios.The conference has been held yearly since 2018. The first and the second editions, i.e., 2018 and 2019, were celebrated in Soria, Spain. The third edition was celebrated virtually but hosted by the Costa Rica Institute of Technology. The fourth edition was hosted by Instituto Politécnico Nacional de México, celebrated in presential and virtual mode in Cancún, México. The fifth edition was hosted by Universidad de Cuenca and celebrated in presential and virtual mode in Cuenca, Ecuador. The VI Ibero-American Congress of Smart Cities (ICSC-CITIES 2023) was held in a hybrid way (face-to-face and virtual) from November 13th to 17th, 2023, in Ciudad de México and Cuernavaca, hosted and sponsored by the Centro de Investigación en Computación of the IPN and Universidad Autónoma del Estado de Morelos, México. Seventy-five technical presentations were given by researchers from 26 different countries during the ICSC-CITIES 2023. Eleven papers were included as posters. Papers were divided into eleven tracks, i.e., Artificial Intelligence for Smart Cities, Energy, Energy Efficiency and Sustainability, Smart grid, Governance and Citizenship, Smart Economy, Development and Education, Smart Environment, Smart Industry, Smart Mobility, Smart Public Services and Urban Informatics, Big Data, Analytics for Smart Cities & Other developments for Smart Cities; those contributions were selected from a pool of 94 submitted papers, yielding an acceptance rate of 91.4%.ICSC-CITIES 2023 was enriched by three-featured panel discussions focusing on specific aspects of Smart Cities. The first panel explored how new technologies foster the development of new smart cities. The second panel discussed the digitalization of public transportation and its benefits. The final panel examined smart cities from a gender perspective.

Le projet « Sustainable COnservation and REstoration of built cultural heritage » (SCORE) vise à rassembler un groupe intersectoriel, international et multidisciplinaire qui comprend un large éventail d'acteurs - y compris des scientifiques de différentes disciplines, des sociétés de conseil, des organismes de formation et des organisationsnon gouvernementales. – afin de renforcer la recherche collaborative et l'innovation dans la conservation, la restauration et la réhabilitation respectueuses de l'environnement. Intégrer les exigences du patrimoine culturel dans les éléments économiques et sociaux du développement durable devient essentiel et nécessite une main-d'oeuvre hautement qualifiée pour la conception, l'exécution et les travaux de conservation. L'objectif du projet SCORE est de réduire l'empreinte écologique des matériaux et méthodes employés dans la conservation du patrimoine culturel bâti. International audience
