Panama's carbon footprint is an important topic when we talk about climate change and sustainability. This study looks at the CO₂ emissions from traditional vehicles and stoves, and how switching to electric options could make a difference. Our goal is to understand the emissions from these two areas and the potential benefits of going electric. We collected data on vehicle and stove usage at Building #1 of the Technological University of Panama, Victor Levi Sasso campus. Using a mathematical model, we estimated the CO₂ emissions from the vehicles used by staff and students, as well as from the kitchens. We also gathered information from reliable sources to calculate the carbon footprint of both types of technologies. Our findings show that traditional vehicles produce more CO₂ than electric ones, which highlights the benefits of moving towards electric transportation. However, we found that electric stoves could generate more CO₂ than gas ones, indicating that switching to electric stoves might not always be the best choice for reducing emissions right now. Overall, adopting electric vehicles is a great way for Panama to lower CO₂ emissions, but switching to electric cookstoves may not be the best move at this time.

Sonda de osciloscopio de 1 Gigahertz (GHz): diseño, construcción y validación

La necesidad de sondas de osciloscopio de alta precisión en contextos donde no siempre se dispone de opciones comerciales de calidad ha impulsado el desarrollo de esta investigación. Este estudio se centró en diseñar y construir una sonda de osciloscopio capaz de operar en un rango de frecuencia de 1 Hz a 1 GHz, manteniendo la integridad de la señal y minimizando la atenuación. Se realizó una selección detallada de materiales y componentes, como conectores BNC y cables coaxiales RG-58 y RG-6, además de un circuito de compensación ajustable en configuraciones x1 y x10. Las pruebas de rendimiento incluyeron barridos de frecuencia y comparaciones con sondas comerciales para validar la precisión de las mediciones en condiciones de baja y alta frecuencia. La sonda fabricada mostró un rendimiento comparable a las sondas comerciales, logrando una atenuación mínima de señal y un desfase de solo 0,35 dB a 980 MHz. Los resultados obtenidos resaltan la importancia de seleccionar componentes de alta precisión y de un diseño de circuito de compensación adecuado para reducir el ruido y mantener la precisión en aplicaciones de medición electrónica

This study addresses the absence of a comprehensive legal framework that regulates Digital Government in Mexico and protects the user in the Government-Citizen relationship. It aims to analyze the rights to Digital Government in the country considering: 1) the growing relevance and use of Information and Communication Technologies in public management and 2) the principle of legality that governs all state action. The research aims to classify the rights of citizens to Digital Government through a documentary analysis of the institutional and legal framework at the federal level of Digital Government in Mexico during the period 2019-2024, with an approach based on the hierarchy of laws. The findings reveal that the rights to Digital Government can be grouped into five key dimensions: 1) digital social inclusion, 2) access and completion of procedures and services, 3) right to access public information, 4) protection of personal data and 5) emerging rights such as biometrics and electronic voting. In conclusion, the right to Digital Government in Mexico comprises a set of rights defined with their respective regulatory frameworks and others that are still in the process of regulation as technology advances in the country.

Perception of the participants of the XV Helmet Imposition Ceremony (HIC), a rite of passage in Higher Education

In the context of Higher Education, there are rites of passage that mark important moments in a student's career. The Helmets Imposition Ceremony emerges as a pedagogical practice to motivate, retain, and identify participants within their engineering programs. This study was conducted to measure the perception of participants in the latest version held at the UTP Regional Center of Veraguas, assessing their opinions on aspects such as the feelings generated, the symbols used, as well as when and who should participate. A Likert-type survey was administered to the 35 participants; the results showed the symbolic effectiveness of the event, its impact on the students involved, and the tendency to include other disciplines that use helmets in their professional practice in the future, in addition to holding the ceremony midway through their degree programs. To this end, studies are expected to be undertaken to measure the benefits of this event in HEIs on a larger scale.

Evaluation of the effects of soluble minerals in the surface waters of the town of Pajonal, Panama

Thu, 17 Jul 2025 19:37:49 +0000

In the visits prior to the sampling campaign for the preparation of a geological map in the village of Pajonal, it was observed that the waters of all the localities have a whitish color. This article presents the physicochemical analyzes of the collected samples. The objective of their study is to verify the possibility that surface waters are affected in quality by the presence of soluble minerals that make up the Piedra Jabon de Pajonal. Organoleptic methods were used to determine color and odor. A multiparameter was used to obtain pH, temperature, electrical conductivity and dissolved solids. Tests were carried out in laboratories as total solids SM2540 b and heavy metals present in the samples using the ICP-OES Method. In addition, the maximum limits of heavy metals in water were evaluated according to regulations applicable to drinking water, aquatic life, irrigation and aquaculture. A total of 15 samples obtained in the vicinity of the Piedra Jabón de Pajonal outcrops were analyzed. Of which, 13 points correspond to surface water samples and the remaining points were taken in springs. The analysis of the concentration of heavy metals covered a quantity of 36 chemical elements. In conclusion, no minerals contained in the Pajonal Soap Stone have been identified. However, high levels of heavy metals were found in the groundwater samples, considered hydrothermal, which represents a risk for human consumption.
