El pasado jueves 17 se dictó la conferencia "El planeta tierra reacciona" en el que se abordaron temas relacionados a los desastres naturales, medio ambiente y cambio climático, el conferencista fue el reconocido ufólogo guayaquileño Ronald Chávez, quien se ha desempeñado como Embajador del Ministerio de Cultura Universal y posee estudios en explosiones solares, terremotos. Además, es educador de segunda enseñanza, y autodidacta en la materia de las constelaciones y fenómenos naturales terrestres.

La conferencia organizada por el departamento de Vinculación con la Colectividad, a través de la Ec. Liliana Aguirre, tuvo acogida entre los miembros de la comunidad del Barrio Cuba y estudiantes universitarios que participaron de la charla realizada en el Aula Magna, y en la que se pudo evidenciar en videos sobre los diferentes fenómenos naturales y su impacto en el planeta.

La charla duró alrededor de 2 horas en el que se dieron a conocer la evolución del planeta tierra y sus consecuencias. El Lcdo. Chávez ofreció al término de la exposición consejos útiles de prevención de los impactos ocasionados por los fenómenos naturales y los riesgos de origen humano y tecnológico.

Applied Sciences, Vol. 14, Pages 4252: Impact of Ar/CF4 Mixed Gas Flow Rate on Silicon Etching Using Surface Discharge Plasma 17 mayo, 2024
This study examines the effects of varying argon (Ar) and carbon tetrafluoride (CF4) gas flow rates on the etching of monocrystalline silicon substrates using surface discharge plasma. While previous research has primarily focused on the fundamental characteristics and applications of surface discharge plasma in silicon etching, the influence of the gas flow rate on etching […]

Applied Sciences, Vol. 14, Pages 4258: Aerodynamic Analysis of Hovering Flapping Wing Using Multi-Plane Method and Quasi-Steady Blade Element Theory 17 mayo, 2024
In the design of flapping-wing micro-size air vehicles capable of hovering, wings serve as the primary source of hovering power, making the analysis of aerodynamics and aerodynamic efficiency crucial. Traditional quasi-steady models treat the wings as single rigid plane, neglecting the deformable characteristics of flexible wings. This paper proposes a multi-plane method that, in conjunction […]

Applied Sciences, Vol. 14, Pages 4259: RQ-OSPTrans: A Semantic Classification Method Based on Transformer That Combines Overall Semantic Perception and “Repeated Questioning” Learning Mechanism 17 mayo, 2024
The pre-trained language model based on Transformers possesses exceptional general text-understanding capabilities, empowering it to adeptly manage a variety of tasks. However, the topic classification ability of the pre-trained language model will be seriously affected in the face of long colloquial texts, expressions with similar semantics but completely different expressions, and text errors caused by […]

Applied Sciences, Vol. 14, Pages 4257: Characterization of Surface α-Particle Radiation, Internal Traceability and Simulation of Typical Tin Spheres 17 mayo, 2024
Surface α-particle emissivity testing and spectral characterization of two leaded tin spheres (Sn10%Pb90%, Sn63%Pb37%) and one lead-free tin sphere (Sn96.5%Ag3.0%Cu0.5%, SAC305) were carried out. The results show that Sn10%Pb90% Sn spheres have the highest α-particle emissivity; Sn63%Pb37% Sn spheres are the next highest, which is an order of magnitude lower than the α-particle emissivity of […]

This paper proposes a new spacecraft in-orbit launch design using a nonlinear configuration to utilize nonlinear dynamics for the enhancement of vibration isolation and launch performance. The in-orbit launch device has four springs, where the stroke directions of two springs are perpendicular to the launch direction so as to produce nonlinearity with negative stiffness for […]

Molecules, Vol. 29, Pages 2362: Raman Spectroscopy on Free-Base Meso-tetra(4-pyridyl) Porphyrin under Conditions of Low Temperature and High Hydrostatic Pressure 17 mayo, 2024
We present a Raman spectroscopy study of the vibrational properties of free-base meso-tetra(4-pyridyl) porphyrin polycrystals under various temperature and hydrostatic pressure conditions. The combination of experimental results and Density Functional Theory (DFT) calculations allows us to assign most of the observed Raman bands. The modifications in the Raman spectra when excited with 488 nm and 532 nm […]

The potential energy curves (PECs) and spectroscopic constants of the ground and excited states of a LiMg+ molecular cation were investigated. We obtained accurate results for the fifteen lowest-lying states of the LiMg+ cation using the Intermediate Hamiltonian Fock Space Multireference Coupled Cluster (IH-FS-CC) method applied to the (2,0) sector. Relativistic corrections were accounted for […]

Understanding the changes in carbon structure during the mid–low-temperature pyrolysis of low-rank coal is important for efficient utilization. Raman spectroscopy is commonly used to analyze the structural order of carbonaceous materials, but traditional methods may overlook the heterogeneity of coal/char. This research explores the heterogeneity of char structure derived from low-rank coal at 700 °C […]
