Ampliando el enfoque de la soberanía: Fuerzas Armadas de Ecuador frente al crimen organizado transnacional
Authors: Andrade-Vásquez Miguel
Published: January 2024

Según este artículo, el trabajo complementario de las Fuerzas Armadas de Ecuador ha sido ineficaz para confrontar el crimen organizado transnacional (COT). Se argumenta que esta inefectividad responde al enfoque westfaliano de la soberanía, el cual considera que el objetivo de los cuerpos militares es la defensa de las diferentes dimensiones territoriales de un Estado frente a amenazas convencionales. Este enfoque, aún vigente en la política de defensa ecuatoriana, no está en sintonía con nuevas amenazas como el COT y delitos conexos. A partir de un recorrido histórico-conceptual y una revisión de la política de defensa nacional (2002 y 2018), se concluye que la solución no radica en sólo una ampliación jurídica y constitucional de las atribuciones de las Fuerzas Armadas en la esfera del orden público y la seguridad interna, sino en cuestionar y ampliar el enfoque de soberanía, más allá de sus nociones clásicas frente a amenazas centrales para el Estado, como el COT.

Published: January 2024

Various computer programs have been developed for gas lift wells. Existing programs have certain advantages as well as disadvantages. These shortcomings are due to the large number of parameters included in the program, difficulties in ensuring the operation of wells in the interval between optimal and maximum modes in mining conditions, while it is possible to use them in wells, but their application in wells operating with the fountain-gaslift operation method is not intended. Current programs do not allow to group wells and determine the optimal modes of other wells included in the group as a result of processing the three-mode data of one well. For this reason, there is a need to develop it. Compared to other programs in mining conditions, the new computer program, which is easier to use and the accuracy of the obtained results is higher, allows the wells working with the fountain-gaslift and gaslift method to be operated in the interval between the optimal mode and the maximum mode based on the processing of research materials in three modes. With the help of this program, it is possible to calculate the optimal and maximum modes for fountain-gas lift and gas lift wells, graphically describe the results of equal processing in new coordinates and group the wells.

Published: January 2024

El nitrógeno es un nutriente esencial y limitante para los productores primarios marinos, bajo un delicado balance en ambientes oligotróficos i.e. Caribe mexicano. El desarrollo turístico y urbano del Caribe mexicano y, ahora, las arribazones masivas de sargazo pelágico, se identifican como fuentes nitrógeno que pueden alterar las condiciones oligotróficas de las lagunas arrecifales del Caribe mexicano. El objetivo del presente trabajo fue cuantificar el contenido de nitrógeno elemental en las hojas del pasto de tortuga Thalassia testudinum bajo un escenario de diversas fuentes de nitrógeno para determinar la posible contribución de estas fuentes al pasto de tortuga en el periodo de 1991 a 2019 en Puerto Morelos, Quintana Roo. El contenido promedio de nitrógeno fue 1.84±0.22% con mínimo de 1.71% y máximo de 2.20%. Este valor fue muy similar al intervalo establecido para otras lagunas costeras donde está presente este pasto marino. En el periodo de 1991 a 2019, las hojas de T. testudinum no mostraron evidencia de enriquecimiento de nitrógeno, excepto para el periodo de 2014 a 2016, bajo un escenario de arribazón de sargazo pelágico o por intenso pastoreo de las tortugas marinas. El contenido de nitrógeno estuvo en el límite de nitrógeno para su crecimiento, durante la arribazón masiva de sargazo del 2018 al 2019, lo cual supone estrés para el pasto marino bajo una mala calidad del ambiente marino.

Published: January 2024

In the case of a biological threat, early, rapid, and specific detection is critical. In addition, ease of handling, use in the field, and low-cost production are important considerations. Immunological devices are able to respond to these needs. In the design of these immunological devices, surface antibody immobilisation is crucial. Nylon nanofibres have been described as a very good option because they allow for an increase in the surface-to-volume ratio, leading to an increase in immunocapture efficiency. In this paper, we want to deepen the study of other key points, such as the reuse and stability of these nanofibres, in order to assess their profitability. On the one hand, the reusability of nanofibres has been studied using different stripping treatments at different pH values on the nylon nanofibres with well-oriented antibodies anchored by protein A/G. Our study shows that stripping with glycine buffer pH 2.5 allows the nanofibres to be reused as long as protein A/G has been previously anchored, leaving both nanofibre and protein A/G unchanged. On the other hand, we investigated the stability of the nylon nanofibres. To achieve this, we analysed any loss of immunocapture ability of well-oriented antibodies anchored both to the nylon nanofibres and to a specialised surface with high protein binding capacity. The nanofibre immunocapture system maintained an unchanged immunocapture ability for a longer time than the specialised planar surface. In conclusion, nylon nanofibres seem to be a very good choice as an antibody immobilisation surface, offering not only higher immunocapture efficiency, but also more cost efficiency as they are reusable and stable.

Serpientes Jaguar en el arte iconográfico Mochica. Criaturas de la muerte y de la vida
Authors: Gómez Sánchez Javier
Published: January 2024

El arte pictórico mochica, pese a su simplicidad de estilo, revela contener múltiples significados místicos. Sobre sus figuras y formas narrativas recaen siglos de herencia cultural y pensamiento filosófico. Así, comprendida sus técnicas más elementales, puede estudiarse el sentido narrativo y metafórico que encierran. Una de las más recurrentes de esas figuras y metáforas fue la referida al híbrido animal serpiente-jaguar, una criatura mitológica referida a la renovación. Su imagen de regeneración hacía hincapié, en su interpretación más profunda, en el círculo inagotable de la vida tras la muerte; aplicado con especial interés a la agricultura y al sostenimiento del orden humano. La otra visión, la más profana, hacía referencia a la renovación necesaria del poder político; a la muerte y renacimiento de la autoridad de los gobernantes Moche. La estrategia de la élite gobernante mochica pasó por momentos diversos de angustia, especialmente debido a los desastres climatológicos provocados por los aluviones y torrentes no esperados o recibidos sin la debida preparación, lo que ponía a las autoridades, encargadas de tratar con las divinidades y rogar por un clima sin sorpresas, directamente en la diana. Por ello, la regeneración, esto es, la muerte y renacimiento de la cúpula gobernante, resultaba necesaria. A través de ella se hacía constar que las nuevas autoridades habían superado sus flaquezas y volvían, esta vez más fuertes, para seguir ocupando su puesto. El icono con que los mochicas expresaban este fenómeno de agotamiento de la autoridad y su ulterior reforzamiento, fue el de las serpientes con cabeza de jaguar.

Published: January 2024

MHD parabolic flow past an accelerating vertical plate with a uniform temperature has been studied in this paper using both the constant mass diffusion and the Soret effect of rotational action. The fluid in question is a grey Newtonian fluid that conducts electricity, can't be compressed, absorbs and emits light, and absorbs and emits light. The speed, temperature, and concentration curves have been solved using the Laplace transform method. The graphs that demonstrate how several parameters, such as the thermal Grashof, Prandtl, mass Grashof, Soret, and Schmidt number, together with the magnetic field time, and the acceleration parameter, are employed in the equations were created using the MATLAB R2020a software. The speed is likely to rise as mass Grashof or hot Grashof numbers do. It has also been demonstrated that speed elevates as the strength of the magnetic field drops. Soret effect works in enormous way due to its productive and significant applications in the field of science.
A Study of Soret-Dufour Effects on MHD Radiative Casson Nanofluid Flow Past an Inclined Surface with Chemical Reaction
Authors: Giulio Lorenzini  , Prathi Vijaya Kumar  , Shaik Mohammed Ibrahim
Published: January 2024

This study investigates the impact of heat flux induced by concentration gradients (Dufour effects) and temperature gradients (Soret effects) on the boundary layer flow of a Casson nanofluid over an inclined expanding surface. It also considers heat and mass transfer coupled processes, Brownian motion, thermal radiation, chemical reactions, and thermophoresis. A dimensionless problem is formulated using similarity transformations and solved using the homotopy analysis method (HAM). Tables and graphs are employed to illustrate the correlations between influencing factors and physical quantities. It is observed that an increase in the inclination parameter leads to a reduction in skin friction but an enhancement in Nusselt and Sherwood numbers. The inclination parameter causes a decline in velocity, while the opposite trend is observed in the concentration field for the chemical reaction parameter. The Casson parameter decelerates the velocity and accelerates the distributions of temperature and concentration. The findings provide valuable insights into the flow patterns, temperature distribution, and concentration profiles within the system. This information holds significant relevance for designing and optimizing heat transfer systems, energy-efficient processes, and catalytic reactors involving Casson nanofluids. Our claims are validated by comparison with published literature, demonstrating a high degree of agreement.

Published: January 2024

Nowadays, energy demand continuously rises while energy stocks are dwindling. Using current resources more effectively is crucial for the world. A wide method to effectively utilize energy is to generate electricity using thermal gas turbines (GT). One of the most important problems that gas turbines suffer from is high ambient air temperature especially in summer. The current paper details the effects of ambient conditions on the performance of a gas turbine through energy audits taking into account the influence of ambient conditions on the specific heat capacity ( , isentropic exponent ( ) as well as the gas constant of air . A computer program was developed to examine the operation of a power plant at various ambient temperatures and relative humidities. The ambient temperatures ranged from 0 to 45 ºC, with relative humidities from 10 to 90%. The obtained results show that a GT operated at increased inlet air temperatures is characterized by lower net power and thermal efficiency. At higher inlet air temperatures, increased relative humidity has a slight positive impact on the GT cycle net power and its thermal efficiency. Net output power of the GT decreased from 93.3 MW at 15 °C to 70 MW at 45 °C. Its efficiency decreased from 32.32% at 5 °C to 28.3% at 30 °C. Although fuel consumption is reduced, the heat rate as well and the specific fuel consumption (SFC) are enhanced. SFC increased by 5.36% with a 10 °C temperature rise in temperature at a constant relative humidity. Therefore, use of a gas turbine with inlet air cooling and humidification is appropriate for improved GT efficiency.

Published: January 2024

The importance of thermal radiation impacts on electromagnetohydrodynamics (EMHD) hybrid nanofluid movement and heat transference towards stretching/shrinking surface is investigated. The influences of external effects such as suction, heat absorption and generation are also being considered. The hybrid nanofluid chosen for exploration is Graphene Oxide (GO) and Iron Oxide (Fe3O4) as nanoparticles, while water (H2O) is a base fluid. The mathematical modelling in partial differential equations (PDEs) is formulated to ordinary differential equations (ODEs) for simplicity using an appropriate similarity variable. The solution of the reduced ODEs is then computed with the help of bvp4c solver built-in MATLAB software. The findings reveal that the magnetic field augmented the velocity profile, while thermal radiation affects the temperature profiles to amplify. The heat generation and absorption upsurged the heat transfer for GO-Fe3O4/H2O with accompanying effects like plate thickness. It is also worth mentioning that GO-Fe3O4/H2O enhanced skin friction and heat transfer by about 3.2% and 1.6%, respectively, more than Fe3O4/H2O.
Three-dimensional MHD Mixed Convention Upper Convective Flow of Maxwell Fluid Throughout the Past in Thermophoresis and Brownian Motion with the Effects of Diffusion Thermo and Thermal Diffusion Utilizing Nonlinear Radiative Heat Flux
Authors: Rameswara Reddy Yeddula  , Srinivasan Donti Ratnam
Published: January 2024

This article aims to investigate the impact of nanoparticles and magnetohydrodynamics (MHD) on the transfer of heat and mass using a three-dimensional upper-convected Maxwell (UCM) nanofluid flow across a stretched surface. A nonlinear radiative heat flow was included in formulating the equation that describes energy. The nonlinear partial differential equations of the issue are transformed into ordinary differential equations utilizing the similarity transformation. These equations are then solved using the well-known shooting approach in conjunction with the Runge-Kutta integration process of order four. To increase the dependability of our findings make use of the MATLAB. On the velocities, temperatures, and concentrations of the particles, the graphical and numerical representations of the effects of the main parameters, such as the Dufour parameter, the Brownian motion parameter, the Prandtl number, the thermophoresis parameter, and the magnetic parameter, are presented. It has been shown that the flow velocity decreases as a function of both the linear and nonlinear thermal radiation parameters. In addition, increasing values of the Brownian motion parameter have the effect of reducing the nanoparticle concentration profile, the same behavior has observed in the case of thermal diffusion and Diffusion thermo parameters.

Published: January 2024

In the absence of seismic records, this study focuses on using microtremors as surrogates to analyze ground signals during earthquakes. Earthquake engineering uses response spectra to evaluate the structural reaction to vibrations, condensing the complex dynamics required for design. The central objective is to generate response spectra in underdamped systems using Newmark's β method, considering displacement, velocity and acceleration with operations research methodology. The sample consists of 171 points of the Riobamba seismic zonation study. Using environmental microtrepidation results, accelerogram matrices were obtained for each component. Maximum values of displacement, velocity and acceleration were extracted for a natural period of 3 seconds with a damping of 5% and plotted to obtain response spectra. This methodological approach provides a robust analysis of the underdamped response of the system, offering crucial insights for seismic design and engineering.

Objectives: To assess mental health status among people with and without disabilities during the COVID-19 pandemic in Vietnam. Methods: We conducted online quantitative research on 410 people with disabilities (PWD) and 358 people without disabilities in Vietnam. The mental health status was assessed by The Depression Anxiety and Stress Scales (DASS-21). The Chi-square test was used to detect the differences between PWD and people without disabilities. Multivariate logistic regression modeling was performed to evaluate the association between the COVID-19 impacts and stress, anxiety, and depression among PWD, compared to people without disabilities. Results: In our study, the majority of PWD lived in the countryside (57.3%), were female (53.9%), had not completed high school (56.1%), had no religion (74.4%), and were married (53.4%). PWD had a higher median score for stress (8 vs. 2), anxiety (4 vs. 0), and depression (4 vs. 0), compared to people without disabilities. After adjusting for demographic factors and government support during the COVID-19 pandemic in the multivariable logistic regression model, the odds of having stress, anxiety, and depression among PWD were 4.40 times (CI 95%: 2.46,7.88), 3.84 times (CI 95%: 2.31,6.38), and 5.80 times (CI 95%: 2.97,11.31) higher than those without disabilities, respectively. Conclusions: During the COVID-19 pandemic, PWD have a higher level of poor mental health than those without disabilities. PWD with support from the government have the level of poor mental health lower than those who do not. Keywords: Mental health, PWD, COVID-19, Vietnam.

Objectives: This study aimed to describe the care needs among dementia patients in Nam Dong District, Thua Thien Hue Province by using the Camberwell Assessment of Need for the Elderly (CANE) questionnaire, and to examine its related factors. Methods: A cross-sectional descriptive study was conducted on 182 dementia patients living in Nam Dong District, Thua Thien Hue Province. The care needs of dementia patients were examined by using the CANE questionnaire (score range: 0-30). The CANE has shown a good level of reliability (α = 0.87). The multivariate linear regression analysis was undertaken to explore the associated factors of the care needs among dementia patients. Results: The mean score of the subjects' needs was 8.21 ± 7.99 (Min: 0; Max: 30). Met needs were reported most commonly in the following areas: food (34.1%), drugs (29.7%), physical health (25.3%) and looking after the home (24.7%). Meanwhile, unmet needs with the highest proportions included accommodation (30.2%), memory (24.7%), money/budget (24.2%), and information regarding health conditions and treatment (18.1%). Higher health care needs were significantly related to Co Tu ethnic group; unmarried group (including single; widowed; divorced/separated); poor, near-poor household economic status group. Conclusions: Unmet needs are common among dementia patients. Primary health care providers should work with carers to promote social support services as well as health care services that meet all needs of dementia patients and improve their quality of life.
