The environmental complexity arises in the world as an effect of the forms of knowledge, but it is not only a relation of knowledge. This concept emerges from the world interpreted by science as an objective, fragmented and specialized knowledge. Therefore, complexity and systems theory arise at the same time as the environmental crisis is manifested. The research work starts from an idea linked to the formation of current and future generations to achieve sustainability from the direct link of educational centers with society, an experience that is addressed from the university, as a sure way to influence the achievement of sustainable development. It offers a developing vision of the role that the student and the university institution should play in terms of sustainability inspired by a logical model of community bonding, where students figure as central actors in the action process, learning and serving the same community time that they demand from others what they can and should do in the interests of sustainable development.
The purpose of the research is to expose the nature that, in matters of law and social policy, justifies promoting the elaboration and adoption of a regulatory framework that favors the use of renewable energy sources, for the generation of electricity through case analysis in the Province of Manabí. For the accomplishment of the research study has taken into account a brief theoretical analysis on the fundamentals of the regulatory doctrine, where it exposes the conceptual framework of the law and its necessity for the good development of the social relations that derive from the use of the Renewable sources of energy. A study was carried out of the specific regulatory work carried out at the international level, in order to promote the adequate use of renewable energies, as well as a national study presenting an initial vision for the study and establishment of a specific regulatory framework for the case study of the province of Manabí, as well as a group of policies and support measures that could be adopted to promote the integrated use of renewable energy sources and their contribution to the national energy matrix.
Se expone un análisis vinculado a una de las alternativas energéticas sostenibles que en la actualidad se está adoptando con éxito a nivel mundial con el fin de lograr el mejoramiento de la calidad del servicio eléctrico, ahorrar recursos naturales, reducir las pérdidas y contribuir en la disminución de las emisiones de CO2 a la atmósfera. Se muestran los resultados de un estudio relacionado con el uso de una innovación tecnológica para mejorar la calidad del servicio eléctrico en una comunidad aislada, mediante la introducción de tecnología fotovoltaica conectada a la red de baja tensión de un grupo de 20 viviendas que fueron estudiadas. Se muestran los resultados del estudio de carga y consumo horario de energía de las viviendas y se despliega una metodología propia para el diseño de la tecnología fotovoltaica conectada a la red de baja tensión de las viviendas estudiadas; este tiene el potencial de evitar el consumo de energía de la red convencional y la posibilidad de mejorar la calidad del servicio eléctrico, al tiempo que se reducen el monto de la factura eléctrica y las pérdidas.
The production of phenolic metabolites has been optimized in parallel to sugarcane micropropagation in temporary immersion bioreactors (TIBs). Culturing micropropagated plants in 0.4% CO 2 -rich air induced their photosynthetic activity by enhancing the change from a heterotrophic to a photomixotrophic metabolic stage. Under 0.4% CO 2 enrichment, the transcript levels of both phenylalanine ammonia-lyase (PAL EF189195) and ribulose-1,5-biphosphate carboxylase/oxygenase (Rubisco CF576750) increased and were correlated to a 4.6-and 6.3-fold increase in the phenolic levels when plants were multiplied in 20 or 30 g/l sucrose, respectively. A novel application of plant phenolic metabolites as elicitors of resistance to tomato bacterial wilt in the Solanum lycopersicum-Ralstonia solanacearum pathosystem has been identified. The culture media was collected, and the phenolics were sprayed onto tomato plants infected with R. solanacearum, eliciting and/or maintaining an early defense signaling mechanism that resulted in the protection of the plant against the tomato bacterial wilt disease. RT-PCR analyses confirmed that selected genes from defense-related pathways were differentially expressed between plants treated with sugarcane metabolites, non-treated pathogenfree plants, and non-treated plants inoculated with R. solanacearum.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
