Authors: Gallardo Karina , Hamad Khaled , Escobar-Ortiz Jorge
Published: January 2025

The use of submerged vanes has been experimentally validated as an effective method for controlling local scour and stabilizing riverine structures. This study evaluates the efficacy of submerged vanes in mitigating local erosion around a square bridge pier. Four experiments were conducted under controlled conditions in the sedimentation channel of the Laboratory of the Faculty of Civil and Environmental Engineering at the National Polytechnic School in Quito, Ecuador. Acrylic submerged vanes were installed upstream of the pier at a 15° attack angle relative to the flow direction, aiming to modify the velocity distribution and sediment transport dynamics. The experimental results showed that submerged vanes reduced the maximum scour depth by up to 60 % compared to tests without vanes, with an average reduction of approximately 58 %. This significant reduction was attributed to the generation of vortices that redistributed sediment, resulting in shallower and more stable scour holes. Furthermore, the average sediment transport downstream decreased by approximately 40 %, further validating the vanes' efficiency in controlling erosive processes. The vanes demonstrated consistent effectiveness across varying flow rates and sedimentation conditions, underscoring their practical adaptability. By modifying flow dynamics and reducing bed shear stress, the vanes provided reliable scour protection regardless of the hydraulic conditions tested. This study highlights the submerged vanes' potential as a viable, economical, and innovative solution for protecting riverine infrastructures, particularly bridge piers, against erosive forces. Their scalability and adaptability to different hydraulic conditions make them suitable for mitigating scour in river systems with high sediment transport activity and for retrofitting existing infrastructure to enhance its stability. This research contributes to the body of knowledge on local scour mitigation by presenting a replicable experimental methodology and emphasizing the practical applicability of submerged vanes. in hydraulic engineering. The findings suggest that submerged vanes are not only effective but also cost-efficient, making them a promising alternative to traditional scour protection methods such as riprap or aprons.

Published: January 2025

The hydrocarbons that contaminate water are difficult to remove, among other things, due to their hydrophobic nature. A surfactant is one way to facilitate contact between the treatment agents. This research prepared a biological surfactant from whey fermentation through Streptococcus thermophilus bacteria. To optimize its production, a complete factorial design was carried out, varying the factors temperature (38, 40, and 42 °C) and time (24, 48, and 72 hours), and the response variable is the amount of surfactant produced. It was found that the highest performance was obtained at 40ºC and 48 hours. The biosurfactant was characterized to determine hemolytic activity, Parafilm, oil dispersion, emulsification index (63.64 %), and surface tension (52.7 mN/m). The ecotoxicity test with Daphnia magna confirmed that the biosurfactant is environmentally friendly. Finally, a bioremediation process was applied during the 45 days when more than 50 % engine oil removal was achieved.

Published: January 2025

Urban driving worldwide is characterized by frequent vehicle idling due to traffic congestion, which significantly impacts fuel consumption and vehicle emissions. While strategies such as eco-driving techniques and start-stop systems have been studied extensively in various regions, limited research has been conducted to assess their effects in Latin America. This study evaluates the impact of idling, traffic, and ecodriving on fuel consumption and well-to-wheel (WTW) CO₂ emissions in urban taxi operations under real traffic conditions in Ecuador. Real-world driving data were collected using on-board diagnostics (OBD). A key innovation of this research is the assessment of alternative scenarios, with reduced idling times and power demand, based on the Vehicle Specific Power (VSP) approach. As result, five scenarios were examined: baseline, eco-driving, low traffic, start-stop technology, and a combined scenario. The results shows that urban driving resulted in the highest WTW CO₂ emissions (354 gCO₂/km) compared with rural and highway driving. The combined scenario, which merges lower power demand with start-stop technology, achieved the greatest improvements, reducing WTW CO₂ emissions and fuel consumption by 15% compared to the baseline scenario. Annually, the combined scenario could avoid 3.68 tons of CO₂ emitted per vehicle and fuel savings of 870 USD. These findings underscore the potential of ecodriving and start-stop technology in reducing fuel consumption and emissions to mitigate the environmental impact of road transportation.

Interventions Supporting New Graduate Nurse Transition into Critical Care: A Systematic Review
Authors: Vanderspank-Wright Brandi
Published: January 2025

Background: New graduate nurses have reported feelings of disorientation, discouragement, overwhelm and lack of confidence as they transition from nursing school to the practice environment. These feelings and a poor transition to practice can lead to burnout and turnover.  New graduate nurses generally have a high turnover risk.  Given the demands of specialty nursing practice environments like the intensive care unit, new graduates transitioning to critical care may be at an even higher risk of a poor transition to practice and risk of turnover.
Aims: To present preliminary findings from a systematic review that aimed to identify, describe and report on the effectiveness of interventions that support new graduate nurse transition into critical care settings.
Methods: A systematic review modelled on Joanna Briggs Institute methodology was designed.  A systematic, peer-reviewed search was conducted in the following databases: OvidMEDLINE ALL, Embase Classic+ Embase, PsychINFO on OVID, CINAHL and Education Source on Ebsco, Nursing and Allied Health and ERIC databases, in addition to a grey literature search. For inclusion, the population of interest was new graduate nurses and all forms of intervention about transitioning new graduate nurses into critical care clinical practice were considered.  Contexts of care encompassed all critical care settings as well as emergency departments.
Findings: At this stage of the review, twenty-six articles met inclusion criteria encompassing interventions implemented in four countries: USA, Canada, China and Australia. Findings related to intensive care units as well as emergency departments were reported. All interventions were unique in nature resulting in a significantly heterogeneous sample.  Where qualitative designs were used, four synthesized themes were generated.
Conclusions: Preliminary review findings suggest that, to date, interventions implemented to support new graduate nurse transition into intensive care unit and emergency department contexts are unique and thus heterogeneous in nature.  Despite the heterogeneity, common intervention elements are discernable and provide some direction regarding practices that support new graduate transition into critical care.

Published: January 2025

The mangrove ecosystem in the Banyak Islands faces urgent challenges due to environmental pressures, highlighting the need for accurate identification and conservation efforts. Mangrove forests provide crucial ecological benefits, making their preservation vital for sustainable regional development. To address these challenges, this study analyzed changes in mangrove vegetation on Tuangku Island, part of the Banyak Islands Marine Natural Park (BIMNP), over a decade (2010–2020). The methodology utilized Landsat imagery and ALOS PALSAR data, which were analyzed through the Google Earth Engine platform. Spectral index combinations, including NDVI, NDMI, MNDWI, and MVI, were analyzed using random forest classification, a tree-based machine learning algorithm. The study's methodology revealed that the total estimated mangrove area was 818.21 hectares in 2010, increased to 939.91 hectares in 2015, and then slightly decreased to 899.96 hectares in 2020. These findings indicate an initial expansion of mangrove vegetation followed by a decline, suggesting fluctuating environmental conditions or human impact over the period studied. The findings highlight the critical need for continuous monitoring and adaptive management practices to support the long-term sustainability of the mangrove ecosystem within the BIMNP. Based on these findings, we recommend implementing targeted conservation measures and further research to understand the underlying causes of the observed changes, thereby supporting the region's sustainable development and ecological health.

Authors: Hidayat Fakhri Rhamadian , Bahruni  , Trison Soni
Published: January 2025

Social forestry symbolizes a sustainable forest management strategy, where local communities are important in strengthening socio-economic aspects, namely welfare and environmental sustainability. Increasing community welfare depends on collective efforts of social forestry, regional regulations, institutional structures, and cooperative with various stakeholders. Subsequent analysis employed the stakeholder analysis model, which scrutinizes stakeholders' roles in natural resource management. The examination compares roles outlined in policy with stakeholders' actual engagement. Consequently, the research provides insights into how stakeholders contribute to social forestry business development based on two critical factors: interest and influence. Results indicate that stakeholders' roles and contributions are substantially influenced by policy, especially concerning their interests and impact on community business ventures in social forestry. Stakeholder analysis reveals that governmental bodies, as mandated by policy, predominantly occupy quadrant II, tasked with aiding community groups in advancing social forestry businesses. However, quadrant I also encompasses governmental entities, albeit with limited involvement in community group activities. QuadrantsIII and IV underscore the diverse roles stakeholders assume within their respective domains, reflecting their interests and influence on business development initiatives to empower the community and improve the livelihood. This research aims to formulate tactics to enhance stakeholder involvement in implementing nation policies for fostering social forestry enterprises within the FMU South Bandung. The tactics need support of each party, especially the social forestry regulation in developing the business and capacity agency in measurement of accessible market, business plan, valuable product and good forest institutions.

Authors: M. Lapo Henrique , T. Chacon-Mikahil Mara Patrícia , V. Sardeli Amanda
Published: January 2025

Objective: Although heart rate variability (HRV) has been a useful and accessible tool to monitor recovery from athletes’ training, it is not clear if it reflects changes in psychophysiological factors. The aim of these study is to identify, through a systematic review and meta-analyses, whether the psychophysiological factors are associated with alteration in heart rate variability (HRV) in sports.

Methods: We searched in four databases (PubMed; Scopus; Cochrane; Web of Science) for studies assessing the association of root mean square of successive differences between normal heartbeats (RMSSD) with a variety of psychophysiological outcomes in athletes of any modality.

Results: After initial search, we selected 12 studies with 27 study arms for analysis. First, we combined 19 study arms in a meta-analysis testing the correlation between HRV and the psychophysiological factors at baseline (Meta 1). Second, we combined 9 study arms in a meta-analysis testing the correlation between HRV and changes in psychophysiological factors within a training period (Meta 2). We analyzed the following psychophysiological factors: stress, sleep deprivation, fatigue, muscular soreness, mood, and hormonal changes (cortisol). summary, there was no significant association between the HRV and the psychophysiological factors in both meta-analyses (Meta 1: r = 0.084, P = 0.167; I² = 20%, P-value for heterogeneity = 0.215; and Meta 2: r = 0.268, P = 0.131, I² = 65.2%, P-value for heterogeneity = 0.003).

Conclusion: We were not able to confirm the association between HRV and any psychophysiological factors by meta-analysis, but it could be due to inherent limitations of this type of analyses. To test whether this associations truly exist, future meta-analysis will need to include studies with much larger sample size and standardize the methods between studies to reduce heterogeneity. Longitudinal studies will be fundamental to understand the causal relationship between these factors to ultimately improve training monitoring tools for better recovery in athletes.

Authors: Palomar-Pardavé Manuel Eduardo
Published: January 2025

This work entails a review of the research conducted at “Universidad Autónoma Metropolitana”, UAM, on the nucleation and growth phenomena involved during the electrochemical phase formation processes (EPF). Specifically, these processes include metal electrodeposition, electrosynthesis of conductive polymers or synthetic metals, anodic film formation, and the electrochemical condensation of surfactant micelles. The primary contributions of these studies focus on developing chemical-physical theoretical models capable of determining the mechanism and kinetics of these EPF processes. This is achieved through the analysis of experimental potentiostatic current density transients recorded in both aqueous and deep eutectic solvents. Furthermore, the resulting modified electrodes are applied to various significant applications, such as green energy generation using direct alcohol fuel cells, the development of electrochemical sensors for neurotransmitters and other biologically important substances, and corrosion and environmental protection.

Las principales contribuciones de estos estudios se centran en el desarrollo de modelos teóricos fisicoquímicos capaces de determinar los mecanismos y la cinética de estos procesos EPF. Esto se logra a través del análisis de transitorios potenciostáticos de densidad de corriente experimentales registrados en disolventes acuosos y eutécticos profundos. Además, los electrodos modificados resultantes se utilizan en diversas aplicaciones significativas, como la generación de energía verde mediante celdas de combustible de alcoholes directos, el desarrollo de sensores electroquímicos para neurotransmisores y otras sustancias biológicamente importantes, así como la protección contra la corrosión y la protección ambiental.

A Langmuir-Hinshelwood kinetic model is proposed to describe the anisole hydrodeoxygenation over a Ru/TiO2 catalyst in a continuous fixed-bed reactor. Key operating parameters, such as pressure, temperature, and weight hourly space velocity, were studied to ensure operation within the kinetic regime. The proposed kinetic model was successfully validated, and two adjacent catalytic sites were considered: one dedicated to the dissociative adsorption of hydrogen and the other to the adsorption and reaction of anisole and its reaction products. The model demonstrated a good fit with the experimental data, revealing a preference for the demethoxylation pathway leading to benzene formation over the demethylation pathway, which favors phenol formation. Characterization of the Ru/TiO2 catalyst using XRD, TPR-H2, TPD-NH3, and XPS revealed the presence of highly dispersed Ru particles and oxophilic sites, including both acidic sites and oxygen vacancies, validating the two-site model. The kinetic parameters indicated that the conversion of cyclohexanol to cyclohexane was the fastest reaction step, and the demethoxylation pathway was favored over the demethylation on the Ru/TiO2 catalyst.
 
Resumen. Se propone un modelo cinético Langmuir-Hinshelwood para describir la reacción de hidrodesoxigenación de anisol utilizando un catalizador Ru/TiO2 en un reactor de flujo continuo de lecho fijo. Se evaluaron inicialmente las condiciones de operación, como la presión, temperatura y velocidad espacial, con el fin de asegurar que el sistema opere dentro del régimen cinético. El modelo considera la presencia de dos sitios catalíticos adyacentes: uno destinado a la adsorción disociativa del hidrógeno y otro para la adsorción y reacción tanto de anisol como de sus productos de reacción. El modelo mostró un buen ajuste con los datos experimentales, indicando una ruta preferencial hacia la desmetoxilación, que produce benceno, frente a la desmetilación, que favorece la formación de fenol. La caracterización del catalizador Ru/TiO2 mediante técnicas de XRD, TPR-H2, TPD-NH3 y XPS reveló la presencia de partículas de Ru0 altamente dispersas y sitios oxofílicos superficiales, incluidos sitios ácidos y vacantes de oxígeno, lo que valida el uso del modelo de dos sitios propuesto. Los parámetros cinéticos indicaron que la conversión de ciclohexanol a ciclohexano es el paso de reacción más rápido, y se favoreció la ruta de desmetoxilación sobre la desmetilación en presencia del catalizador Ru/TiO2.

Published: January 2025

The passage from non-substituted quinone to hydroquinone moieties involves the exchange of two-electron and two-protons, however, the presence of hydroxyl groups in the α position to the carbonyl group of the quinone induce a mechanistic change in which the quinone plays the role of electron acceptor and proton donor. This feature promotes a self-protonation mechanism which can be characterized in the framework of the ECE-DISP theory. However, when additional hydroxyl groups are contained in the quinone structure, hydrogen bonding becomes an additional competition factor that was studied in this work using a series of synthetic and natural quinones with different structures. The number of hydroxyl groups on the quinone structure was studied from the point of view of electrochemical mechanisms and descriptors of reactivity. Cyclic voltammetry, mechanistic simulation and electronic structure calculations were used as an approach to understand the interplay between electron transfer, proton transfer and hydrogen bonding association in α-hydroxyquinones.
 
Resumen. La conversión quinona-hidroquinona involucra el intercambio de dos electrones y dos protones; sin embargo, la presencia de grupos hidroxilo en la posición α respecto al carbonilo de la quinona, induce un cambio mecanístico en el cual el núcleo quinoide juega ahora el papel de acceptor electrónico y donador de protón. Esta característica promueve un mecanismo de autoprotonación que puede ser caracterizado mediante la teoría ECE-DISP. Sin embargo, cuando hay grupos hidroxilo adicionales dentro de la estructura quinoide, la formación de puentes de hidrógeno se convierte en una ruta competitiva adicional, la cual fue estudiada en este trabajo empleando una serie de compuestos sintéticos y naturales. El número de grupos hidroxilo y su influencia fueron estudiados desde el punto de vista de mecanismos electroquímicos y descriptores de reactividad. A través del uso de voltamperometría cíclica, simulación mecanística y cálculos de estructura electronica, se realizó una aproximación para comprender la interrelación entre la transferencia protónica, electrónica y la asociación a través de puentes de hidrógeno en α-hidroxiquinonas.
