Photovoltaic System Implementation in Baltra and Puerto Ayora Islands

In the research, an analysis of the impact of the photovoltaic systems installed in two islands of the Galápagos archipelago is made. In this sense, a series of calculations has been used to find the significant values that have allowed us to choose the specific devices for this project. A modeling study was analyzed to quantify the total energy of the system, the number of possible modules to be installed, the amount of energy to be stored according to the type of batteries and the ampere-hour (Ah) that the regulation set must support of the electric current. The socio-economic and environmental impact of the system on Baltra Island was assessed with an example and estimations to make it explicit, the results of the surveys used are shown through which the most significant results were exposed, exposing that the photovoltaic systems in stage of implantation do not affect the environment, flora and fauna, its greatest impact is in the use of land

Traditional Pedagogical Trends and Their Impact on the Decline in the Student Population

Traditional education is one of the most common practices in 21st century teachers, despite the advances and efforts made in training and workshops that allow them to strengthen and improve their teaching practice, this has not yet managed to change the conformist bases that produce traditionalism, in this research the traditional pedagogical tendencies and their incidence in the reduction of the student population in high school, of the Honorato Vásquez Fiscal Educational Unit, of the Santa Ana canton, their consequences or effects that generate this type of pedagogy or practice, from an educational reality in the social, economic, cultural, how education is perceived by the authors involved in the educational process and the importance of a pedagogical update. To support the hypothesis, deductive, analytical methodology was used, the application of a brief survey through an online form for the teachers of said institution, the results showed that traditional pedagogy is present in their daily activities, in the direction of content

Exceptional Oxygen Reduction Reaction Activity and Durability of Platinum–Nickel Nanowires through Synthesis and Post-Treatment Optimization

For the first time, extended nanostructured catalysts are demonstrated with both high specific activity (>6000 μA cm_Pt^–2 at 0.9 V) and high surface areas (>90 m² g_Pt^–1). Platinum–nickel (PtNi) nanowires, synthesized by galvanic displacement, have previously produced surface areas in excess of 90 m² g_Pt^–1, a significant breakthrough in and of itself for extended surface catalysts. Unfortunately, these materials were limited in terms of their specific activity and durability upon exposure to relevant electrochemical test conditions. Through a series of optimized postsynthesis steps, significant improvements were made to the activity (3-fold increase in specific activity), durability (21% mass activity loss reduced to 3%), and Ni leaching (reduced from 7 to 0.3%) of the PtNi nanowires. These materials show more than a 10-fold improvement in mass activity compared to that of traditional carbon-supported Pt nanoparticle catalysts and offer significant promise as a new class of electrocatalysts in fuel cell applications
