Evolución Histórica de los Sistemas Tributarios de México y Honduras: Similitudes y Diferencias
Authors: Rodríguez Aceituno René Fernando
Published: December 2022

El presente artículo tiene como objetivo realizar un análisis sobre la evolución histórica de los sistemas tributarios de México y Honduras, encontrando las similitudes y diferencias que han existido entre ambos países, comenzando en un primer apartado sobre el origen de los impuestos en la humanidad, estudiando la fuente histórica del Derecho Romano en razón de la importancia que ha significado su influencia jurídica, política, económica y social en nuestra cultura occidental. Luego se procedió al estudio de las primeras figuras y mecanismos de recaudación de tributos utilizados por los pueblos autóctonos tanto de México como de Honduras, las reformas político-administrativas que han experimentado estos sistemas, hasta llegar a las actuales estructuras administrativas de cada país.

Uno de los resultados obtenidos, es que ambos sistemas tributarios poseen la similitud en cuanto a la aplicabilidad de los mismos principios fiscales que tuvieron su génesis en el antiguo imperio romano, entre los que se destacan los principios tributarios de proporcionalidad, igualdad, legalidad, utilidad pública e indisponibilidad. Por otra parte, una diferencia entre ambos sistemas radica en el hecho de que México adoptó ciertas medidas recaudadoras de impuestos que eran aplicadas por sus pueblos autóctonos, a diferencia de Honduras, que tiene su génesis en el sistema impuesto por el imperio español durante la época de la colonización.
La Titularidad y Ejercicio de Derecho a la Propia Imagen del Nasciturus en Honduras
Authors: Cantor Rosales Mauricio José
Published: December 2022

La invención de la fotografía en 1829 serviría como principal punto de inflexión para la construcción teórico – jurídica del derecho a la propia imagen, en virtud que este invento propició un cambio de paradigma en la forma de captar y reproducir la efigie humana, ya que previo a su invención, los rasgos físicos de una persona solamente podían ser obtenidos, registrados y reproducidos por medio de la realización de una pintura o escultura; por ello, la fotografía propició el surgimiento de nuevos desafíos normativos para resolver las problemáticas legales derivadas de la captación de la efigie humana sin el consentimiento de su titular.
Por otra parte, los avances tecnológicos imperantes en el siglo XXI, han causado el desarrollo de técnicas por medio de las cuales es posible captar mediante una ecografía tridimensional o cuatridimensional los rasgos físicos del nasciturus, haciendo posible, por tanto, su recognoscibilidad como ser individual. En ese sentido, el presente artículo tiene por objetivo determinar el momento en que la persona humana comienza a ser titular del derecho a la propia imagen, es decir, si la titularidad de este derecho principia antes de nacer o, contrario sensu, inicia una vez que la persona humana tenga existencia legal.

Authors: Kaoudom Korawit , Suttiruengwong Supakij , Seadan Manus
Published: December 2022

The single use packaging is widely used in various products; ranging from food to non-food contact, from commodity to specialty purposes. Most of these materials are derived from non-renewable fossil resources. In a sustainable manner, it needs to be recyclable or compostable. Good mechanical properties together with biodegradability can make the product more recyclable. In this study, the elasticity for films consisting of polybutylene adipate-co-terephthalate (PBAT) blended with polylactic acid (PLA) (10, and 20 %wt), additive and reactive agents were evaluated. The blends were prepared via a twin-screw extruder. The film specimens were prepared by cast film extrusion. The films were then stretched with different ratios (1.5, 2 and 2.5 times) by the uniaxial machine. The mechanical properties, elasticities and surface morphology of uniaxially stretched PBAT and PBAT blend films were characterized by tensile testing and scanning electron microscope (SEM), respectively. The tensile strength of stretched films tended to improve while the elongation at break reduced at higher stretching ratios. The surface morphology of stretched films revealed that the degree of orientation was increased after higher stretching ratios. The ability to recover in the plastic deformation region of stretched films was increased at the higher stretching ratios.

Published: December 2022

This research studied the utilization of biodegradable polymer for nonwoven fabric production and applied to fabricate a sound absorbing panel by corporate with natural fiber nonwoven fabric. PLA was used as a biodegradable polymer and hemp nonwoven was used as a natural fiber nonwoven fabric. PLA nonwoven fabric was prepared using a melt jet spinning process. The spinning process was carried out at 250 and 260°C with screw speed of 10 rpm and air blown pressure of 0.3 and 0.5 MPa. The die-to-collector of fabric production was studied at 30 and 60 cm to compare the nonwoven fabric product property. It was found that the process temperature, air pressure and die-to-collector distance have significant effects on the nonwoven fabric thickness, GSM, and fabric density. Air permeability decreased with high fabric thickness as well as fine fibers which supported the property of sound absorbing panels. Therefore, the suitable conditions for sound absorbing panel fabrication were processed at temperature of 260°C, air pressure 0.5 MPa and die-to-collector distance of 60 cm. Sound absorbing coefficient measurement revealed that GSM fabric thickness had an effect on increasing sound absorption. The effect of nonwoven sheet order and arrangement of PLA nonwoven and hemp nonwoven of 3 layers sandwich indicated that the layers order of PLA/PLA/Hemp had high sound absorbing coefficient that was comparable with PLA/PLA/PLA due to fiber size and arrangement.

The paper concludes that as per guidance of UN collective security patrols, forces had to be raised in CTF model. The punch line is that no country could be a ‘Net Security Provider’ in IO region.
Russia’s permanent military presence in the Syrian Tartus port for the coming 49 years: Increasing maritime security challenges in the region
Authors: Zafar Ayesha
Published: December 2022

Relations between states are always the result of permanent interests because in international relation there can never be permanent friends. Today, the changing geopolitical dynamics have made all the states engage in a struggle to maintain dominance across the world. Consequently, Russia’s leasing the Tartus port from Syria for the coming 49 years is directional towards the same geopolitical interest of making Russia resurge. Nevertheless, this decision is going to have multiple implications for the maritime security of the region as Russia’s permanent military presence on the Tartus port close to Mediterranean and black sea will make it a geopolitical hotspot for the major power great game. Alongside, the region has become home to numerous non-traditional security threats in the maritime domain including drug trafficking, piracy, illicit trade, marine terrorism, etc. Therefore, this research paper is an attempt to highlight how Russia’s presence in the Tartus port located in Syria is going to shift the regional dynamics. It endeavors to analyze the amassed maritime security challenges in the region by particular reconnoitering the tug of war between the US and Russia and the non-traditional threats that have made it a point of contention between states across the region.
“Ella te aplastará la cabeza”: Santa María de Guadalupe vence a la serpiente en la fiesta de Potosí (1601)
Authors: Peña Beatriz Carolina
Published: December 2022

En Potosí, el 30 de septiembre de 1601, uno de los cuadros parateatrales del juego de la sortija, un torneo programado en las fiestas en honor de Santa María de Guadalupe, se diseñó para demostrar que cuando Dios maldijo a la serpiente en Génesis 3:15 y le pronosticó que su cabeza sería pisada, se refería a María como la enemiga de la tentadora y que, en efecto, fue la Virgen quien ejecutó este acto de dominio sobre el Mal. Tal discurso visual cifrado en un performance denso, pero muy divertido, se oponía a las enseñanzas de Lutero y, en general, a las condenas de los protestantes, quienes percibían mariolatría en esa atribución. Para los luteranos, Génesis 3:15 consiste en un protoevangelio, es decir, una profecía sobre la venida de Cristo a restaurar a la humanidad del pecado. Este trabajo analiza la divisa, el carro triunfal, los personajes y otros elementos del programa iconográfico del Príncipe Tartáreo para desentrañar el entramado de los valores simbólicos que, en un afán contrarreformista, atribuyen a María un papel clave en la salvación.

Provincia y novela en los inicios literarios de Elvira Orphée: Dos veranos (1956)
Authors: Martínez Zuccardi Soledad
Published: December 2022

A partir del poco estudiado primer libro de Elvira Orphée (Dos veranos, 1956), el artículo reflexiona acerca de los inicios literarios de la autora, llamando la atención sobre dos audaces apuestas de su entrada en escritura: la elección de un género (la novela) y de un espacio (la provincia). Revela el carácter pionero y singular de esas orientaciones inaugurales –que tendrán sus continuidades en la obra posterior de Orphée– en relación con dos variables contextuales: el incipiente auge de la narrativa escrita por mujeres y la también incipiente aparición de un conjunto de novelas sobre Tucumán. El análisis se detiene en el espacio representado en Dos veranos: un universo precario signado por el tedio, las carencias, la rabia, la humillación. Propone que, lejos de todo idilio regionalista, la novela despliega un examen crítico de la provincia y de quienes la habitan (personajes muy complejos, plagados de matices). La provincia está directamente ligada en el texto con la carencia lingüística: el protagonista y otros personajes no pueden hablar porque no cuentan con las palabras, en el marco de un desigual reparto lingüístico-territorial en un país de centros y periferias.
Procesos testimoniales y memoriales: contradicciones y reconstrucciones del testigo en la novela gráfica Los surcos del azar de Paco Roca
Authors: Biedma Amado Malen
Published: December 2022

En la novela gráfica Los surcos del azar (2013) del español Paco Roca, se recuperan, a través de una entrevista ficticia con su protagonista, los hechos (históricos) vividos luego de la Guerra Civil Española. Más precisamente, la vida en el exilio y la participación española en la liberación de Francia con la compañía denominada La Nueve. Si bien la instancia testimonial está ficcionalizada, el testigo está basado en un personaje real y la búsqueda de una representación fidedigna de los sucesos marca el desarrollo de la historieta. En este trabajo nos adentraremos en la expresión de la memoria colectiva subterránea que aquí se realiza, ya que el silencio y el olvido sobre dichos acontecimientos son restaurados a través de la instancia testimonial. También, reflexionaremos sobre la elección de este medio artístico a través de la importancia de la oralidad y del pasaje constante del tiempo pasado (lo rememorado) al tiempo presente (el testimonio). Es de nuestro interés observar ambos elementos asociados a las posibilidades propias del cómic. Por último, buscaremos analizar la identidad vedada y contradictoria de la figura del derrotado/entrevistado y la importancia de la atestiguación para la reconstrucción de sí.

Antibiotic resistance is a global, far-reaching phenomenon. Natural resistance to antibiotics, expressed or inducible, is common in Enterobacterales and can occur through the production of different enzymes such as penicillinases, ESBLs or cephalosporinases. In association with other resistance mechanisms, strains that lead to untreatable infections can emerge. Improper infection control measures are responsible for the selection and spread of these strains. The dissemination of acquired Extended-Spectrum Beta-Lactamases (ESBLs) across the globe is well known, a wide spectrum of enzymes being responsible for their different hydrolytic activity. Another important set of enzymes, the cephalosporinases (with the chromosomal cephalosporinase AmpC as the most important), are also concerning as their hyper-expression can alter wide spectrum beta-lactams, like carbapenems. These mechanisms can be readily observed through phenotypic tests, like antibiotic interactions on the disk diffusion antibiogram, or derepression / inhibition of enzymes using key antibiotics. Keywords: ESBL, cephalosporinase, AmpC, carbapenemase, cloxacillin, oxacillin, antibiotic resistance, antibiogram, Enterobacterales

Published: December 2022

The environmental pollution problem of Sinochem Chongqing Fuling Chemical Co., Ltd. is serious. Fuling District Party committee and Fuling District government relocated the chemical plant as a whole and started the ecological restoration project. However, the investigation found that soil covering greening failed to fundamentally eliminate the harm caused by phosphorus slag to the environment. Therefore, the resource utilization of phosphorus slag is imperative. The application of dolomite rich phosphorus slag in the construction industry not only improves the environment, but also reduces the production cost of self-insulation wall materials. In this experiment, dolomite rich phosphorus slag was calcined at 600 ℃, 700 ℃ and 800 ℃ respectively to obtain light calcined dolomite, which was mixed into modified fly ash cement composite mortar to prepare self-insulation wall material. The mechanical properties, water absorption, bulk density and thermal insulation of the specimens were tested after curing for 7 and 28 days respectively. The conclusions are as follows: when the calcination temperature of dolomite rich phosphorus slag is 700 ℃, the specimen has the best mechanical properties, the lowest water absorption, the largest bulk density and the best thermal insulation.

Experimental Study on Strength Characteristics of Zinc Contaminated Soil Solidified by Cement-Metakaolin-Limestone
Authors: Fu Shenjing , Sun Xinpo
Published: December 2022

In order to reveal the effect of curing agent ratio variable and curing age on zinc heavy metal contaminated soil solidified by cement-metakaolin-limestone (LC3) ternary mixture, artificial contaminated soil and curing agent were used to simulate the solidification of contaminated soil. Through a series of laboratory tests, the change rules of unconfined compressive strength and electrical conductivity after curing were analyzed. It is found that with the increase of curing age, the stronger the compressive strength is, the lower the moisture content is. The compressive strength of solidified soil decreases with the increase of moisture content, showing an obvious correlation. Thus it can be seen that the coupling substitution of high territory and limestone for cement can obtain lower moisture content and higher strength and excellent mechanical properties at a relatively early age. The pH value of solidified soil increased to 9.68-10.78. Considering many factors, the solidification effect of zinc heavy metal is the best when the ratio of cement, metakaolin and limestone is LC3-3.

Research on the Correlation Between the Lattice Enthalpy of Ionic Compounds and Melting Points
Authors: Zhang Jiahua
Published: December 2022

Ionic compounds own different crystal structures from molecular compounds due to the electrostatic force, generating affinities between cations and anions. The lattice energies are made strong and require large energy to break the solids. This paper is used to illustrate the influence of different factors on lattice enthalpy, and correlations between lattice enthalpy and melting points, Regarding carbon fibers as templates, trying to find out if there were theoretically possibilities to utilize ionic crystals more in industrial engineering. Several graphs are made based on the database. Research shows that ion charges are direct proportional to the strength of lattice energy; while ionic radius own inverse relationships. However, unexpected results have been found toward melting points, claiming no obvious effect is made by lattice energies. The reason might contribute to the ideal assumption in terms of lattice enthalpy, assuming they were all in perfect form.

We consider a discrete predator-prey model with competition between predators in this paper. By simplifying the corresponding continuous predator-prey model, and using the semidiscretization method to obtain a new discrete model, we discuss the existence and local stability of nonnegative fixed points of the new discrete model. What’s more important, by using the bifurcation theory, we derive the sufficient conditions for the occurrences of Neimark-Sacker bifurcation and the stability of closed orbit bifurcated. Finally, the numerical simulation are presented, which not only illustrate the existence of NeimarkSacker bifurcation but also reveal some new dynamic phenomena of this model.
Effect of Conservation Tillage on Soil and Water Quality
Authors: Hu Yi
Published: December 2022

Soil erosion from cropland has been recognized as a major problem in agricultural production. Conservation tillage is one of many conservation practices developed to reduce soil erosion. Meanwhile, many benefits from conservation tillage system beyond controlling soil loss have been reported. The objective of this work is to briefly review effect of conservation tillage on soil erosion and runoff, soil organic matter, selected soil physical properties, and water quality. Conservation tillage has inconsistent effects on surface runoff and soil loss due to differences in surface roughness and the rate of crop residue left on the soil surface. Increased soil organic carbon (SOC), mainly concentrated near soil surface, has been widely reported in the literature. However, SOC under conservation tillage is labile in topsoil and more recalcitrant in subsoil. Increased SOC leads to improved soil physical properties such as reduced bulk density, increased hydraulic conductivity and infiltration, and improved water retention capacity. Conservation tillage could improve water quality by reducing the total sediment, nitrate, ammonium, and phosphate in the runoff. However, conservation tillage may also facilitate nitrate leaching due to the increase of macropores in soil body.
