A Discontinuous Galerkin Method for the Stationary Boussinesq System
Authors: Colmenares Eligio , Oyarzúa Ricardo , Piña Francisco
Published: July 2022

In this work we present and analyze a finite element scheme yielding discontinuous Galerkin approximations to the solutions of the stationary Boussinesq system for the simulation of non-isothermal flow phenomena. The model consists of a Navier–Stokes-type system, describing the velocity and the pressure of the fluid, coupled to an advection-diffusion equation for the temperature. The proposed numerical scheme is based on the standard interior penalty technique and an upwind approach for the nonlinear convective terms and employs the divergence-conforming Brezzi–Douglas–Marini (BDM) elements of order k for the velocity, discontinuous elements of order

{k-1}

for the pressure and discontinuous elements of order k for the temperature. Existence and uniqueness results are shown and stated rigorously for both the continuous problem and the discrete scheme, and optimal a priori error estimates are also derived. Numerical examples back up the theoretical expected convergence rates as well as the performance of the proposed technique.

 1.6 mm3. The hexagonal motifs are embedded on inexpensive FR-4 lossy substrate. Thereafter, a circle with radius 1 mm is etched at the center of each hexagonal motif. Inverted L-shaped stubs are employed to attain efficient isolation between the nearby antenna elements. Four inverted L-shaped stubs are included to further enhance the isolation and eliminate the antenna size increment simultaneously, by suppressing the surface waves. Before using the decoupling approach, the MIMO antenna had an impedance bandwidth of 6.7 GHz and an isolation of −20 dB. The suggested antenna’s impedance bandwidth and isolation are 5.83 GHz and −52 dB, respectively, after using a decoupling approach (inverted L-shaped stub). The proposed MIMO antenna had a peak gain and radiation efficiency of 3–7 dBi and better than 90% (with decoupling), 2.75 to 6 dBi and greater than 60% (without decoupling). To verify the proposed design, a prototype was developed to compare the simulated parameters with the measured one. The envelope correlation coefficient (ECC) was less than 0.05, and channel capacity loss (CCL) less than 0.3 was achieved with DGS. Besides, scattering matrix such as return loss S
11 and transmission coefficient S
21 between two elements, radiation pattern, and current distribution was also favorable. Thus, the proposed MIMO antenna is advantageous to be used for C-band applications such as developing new generation air-borne and space-borne radars, as well as X-band applications.

This approach reduces the mixed BVP under consideration to a system of pseudodifferential equations.

Properties of general Fourier coefficients of differentiable functions
Authors: Tsagareishvili Vakhtang
Published: July 2022

The paper deals with problems of convergence of the series of moduli of the difference of general Fourier coefficients of functions from some differentiable class. It is shown that the good differentiable properties of a function do not guarantee the convergence of the series of moduli of the difference of general Fourier coefficients of this function. We explain the bounded variation of a sequence of general Fourier coefficients of a function from some functional class. We also find the conditions on the functions of an orthonormal system (ONS) under which the sequence of Fourier coefficients of any function from the differentiable class is of bounded variation. It is established that the resulting conditions are best possible. Studied here is the particular character of a subsequence of ONS.
a-Topics in Italian/Romance and the Cartography of Children’s Inventions
Authors: Belletti Adriana
Published: July 2022

The paper has a specific and focused aim: to unveil a possible route to DOM, the crosslinguistically widely attested phenomenon whereby direct objects are introduced by a preposition, with interpretive constraints. The prepositional marker is ‘a’ in Italian and in (the majority of) Romance. The investigation is based on both comparative data from Romance and on some relevant experimental results from the acquisition of Italian involving a-Topics. The insights that syntactic cartography may provide on the characterization of such route is the leading note of the investigation: a-marking starts out on direct objects topics, only occurring when the (animate) direct object is preposed in the left periphery of the clause; then a-marking involves clause internal direct object topics in the vP-periphery; and finally a-marking is Case related in the small ‘v’ spine; the latter, is also implicated in causatives and in constructions involving benefactive arguments. The acquisition results reviewed indicate the use of left peripheral a-Topics in children’s elicited productions in Italian, which are not attested in the target language, thus illustrating a cartographically defined space of children’s grammatical creativity.
Distress intolerance and pain catastrophizing as mediating variables in PTSD and chronic noncancer pain comorbidity
Authors: Sainero-Tirado Gloria , Ramírez-Maestre Carmen , López-Martínez Alicia E. , Esteve Rosa
Published: July 2022

Objectives

Several studies have demonstrated posttraumatic stress disorder (PTSD) and chronic pain comorbidity. However, there is a lack of research on the psychological variables that might explain their co-occurrence. We investigated the mediating role of distress intolerance and pain catastrophizing in this relationship.

Methods

A moderated mediation model was tested. The sample comprised 114 individuals with chronic noncancer pain (90 women and 24 men; mean age, of 60.04 years [SD=9.76]).

Results

Catastrophizing had a significant effect on PTSD. Distress intolerance mediated catastrophizing and PTSD, and pain intensity moderated this relationship.

Conclusions

New insights are provided into the psychological variables that may explain PTSD and chronic noncancer pain comorbidity.

The mitochondrial intermembrane space protein AIFM1 has been reported to mediate the import of MIA40/CHCHD4, which forms the import receptor in the mitochondrial disulfide relay. Here, we demonstrate that AIFM1 and MIA40/CHCHD4 cooperate beyond this MIA40/CHCHD4 import. We show that AIFM1 and MIA40/CHCHD4 form a stable long‐lived complex in vitro, in different cell lines, and in tissues. In HEK293 cells lacking AIFM1, levels of MIA40 are unchanged, but the protein is present in the monomeric form. Monomeric MIA40 neither efficiently interacts with nor mediates the import of specific substrates. The import defect is especially severe for NDUFS5, a subunit of complex I of the respiratory chain. As a consequence, NDUFS5 accumulates in the cytosol and undergoes rapid proteasomal degradation. Lack of mitochondrial NDUFS5 in turn results in stalling of complex I assembly. Collectively, we demonstrate that AIFM1 serves two overlapping functions: importing MIA40/CHCHD4 and constituting an integral part of the disulfide relay that ensures efficient interaction of MIA40/CHCHD4 with specific substrates.

Penal mediation has been a longtime process of criminal settlement used in the Ngaju Dayak indigenous people in Kalimantan. They used the Belom Bahadat philosophy as a form of reform in the field of criminal procedural law stemmed from the politics of criminal law which makes customary law a part of national criminal law. This article is aimed to analyze the concepts of penal mediation in Indonesia and from the international law perspectives; and the settlement process with Belom Bahadat philosophy-based penal mediation in the Dayak indigenous community and its future use in the national criminal procedural law. This qualitative research applied a sociological juridical approach and utilized primary data obtained from interviews with Dayak traditional elders, secondary data comprising customary peace decisions obtained from Dayak customary institutions, and multidisciplinary approach from international law of penal mediation to uphold the strong concept of penal mediation. The results shown that restorative justice is one of the uniqueness in penal mediation internationally, especially in Germany, Spain, and Indonesia. Furthermore, the use of penal mediation in Dayak community is based on the 96 Articles of the Tumbang Anoi Peace Agreement that has existed since 1894. During a settlement, the penal mediation model applied in the Dayak people can be divided into the Victim Offender Mediation model, as well as Family and Community Group Conferences. Consequently, the formulation of this procedure is expected to be a study material in the renewal of criminal law legislation, specifically the Criminal Procedure law provisions in Indonesia.

Chronicle of a discovery: the retinoic acid receptor
Authors: Giguère Vincent , Evans Ronald M
Published: July 2022

The landmark 1987 discovery of the retinoic acid receptor (RAR) came as a surprise, uncovering a genomic kinship between the fields of vitamin A biology and steroid receptors. This stunning breakthrough triggered a cascade of studies to deconstruct the roles played by the RAR and its natural and synthetic ligands in embryonic development, skin, growth, physiology, vision, and disease as well as providing a template to elucidate the molecular mechanisms by which nuclear receptors regulate gene expression. In this review, written from historic and personal perspectives, we highlight the milestones that led to the discovery of the RAR and the subsequent studies that enriched our knowledge of the molecular mechanisms by which a low-abundant dietary compound could be so essential to the generation and maintenance of life itself.

Published: July 2022

Cisplatin is currently used in the treatment of numerous types of tumors, such as head and neck, esophagus, bladder, testicle. However, the cisplatin use is limited due to its cytotoxic effects. Thus, considering its side effects, lines of research are looking for new technologies to reduce the dose of the chemotherapeutic agent needed to control the disease, which may reduce these side effects. The objective of this work was to perform the internal dosimetry of 191Pt radioisotope derived from the activation of natural cisplatin, thus contributing to the evaluation of the feasibility of a new radiopharmaceutical of natural cisplatin activated by neutrons for application in humans. The dosimetry was obtained with Monte Carlo simulations using two stylized phantoms developed by authors Dragana Krstic and Dragoslav Nikezic and the ICRP adult reference voxelized phantoms. As results, differences were observed between absorbed doses estimated using the two types of phantoms (analytical and voxelized). The highest doses noted in the analytical phantom were in the kidneys (1.58 mGy/MBq), liver (1.32 mGy/MBq), spleen (1.23 mGy/MBq), bladder wall (0.74 mGy/MBq), gallbladder wall (0.56 mGy/MBq), pancreas (0.41 mGy/MBq), and adrenals (0.39 mGy/MBq). For the voxelized phantoms, the highest doses obtained were: kidneys (1.46 mGy/MBq), spleen (1.13 mGy/MBq), liver (1.11 mGy/MBq), gallbladder wall (0.47 mGy/MBq), adrenals (0.41 mGy/MBq), bladder wall (0.36 mGy/MBq), and pancreas (0.29 mGy/MBq). The effective dose was 0.22 mSv/MBq for the analytical phantom, a value similar to that obtained with voxelized phantoms (0.20 mSv/MBq).

The Sterile Insect Technique, or SIT, is an environment-friendly insect pest control method and uses gamma rays or X-rays to sterilize insects, remaining sexually competitive but cannot produce offspring. The dose control during the SIT procedures is essential for the quality of the irradiated product or material.  Insects that receive too low a dose are not sufficiently sterile and those that receive too high a dose may be uncompetitive. There are few dosimetric systems used for the dose control during the irradiation procedure. The aim of this paper is to characterize the Optically Stimulated (OSL) response of Li2B4O7:Cu,Ag, synthesized by the Nuclear Energy Department of the Federal University of Pernambuco and the MTS-N dosimeters to be used for SIT dosimetry and applied in Moscamed Brazil’s pest and vector control programs. The results were evaluated using the student’s t-test. Applying the hypothesis that the results obtained with the three types of dosimeters are similar, the test showed that with 99% confidentiality the hypothesis is accepted, that is, the results of the three types of dosimeters are similar. It is possible to conclude that the OSL Li2B4O7:Cu,Ag, and the TL MTS-N can be used for dose control during the SIT irradiation procedures.

Published: July 2022

Introduction: Analysis of the outcome of 268 ICU patients in a single-center, as well the impact of viral infection on patients with preexisting medical conditions and how these factors affected survival and hospital stay.

Methodology: Patients admitted to the ICU from March-August, 2020 were retrospectively analyzed under the same protocol at Hospital Alemão Oswaldo Cruz, São Paulo, Brazil. Several factors were considered and the results were presented using 95% confidence intervals. For statistical significance, p <0.05 was adopted.

Results: Patient median age was 72 years, 64,2 years for discharged patients and 79.9 years for those deceased (p<0.001). The most common comorbidities were: systemic arterial hypertension, diabetes, thyroid disease, cardiovascular and kidney disease. Predictors of survival through univariate analysis: myalgia (p=0.001), cerebrovascular disease (p=0.002), COPD (p=0.003), dementia (p=0.000), mechanical ventilation (p=0.000), dialysis (0.000), vasopressor use (0.000), SAPS3 (0.000), lymphopenia (p=0.004), elevated D-dimer (P=0.011), time in ICU before tracheostomy (p=0.002), and performing a tracheostomy (p=0.000). The independent predictors of mortality were: advanced age (p=0.003) and tracheostomy performed in ICU (p=0.002).

Discussion: COVID-19 affects usually older adults, where there already is a higher fatality rate. Acute respiratory distress syndrome is the primary cause of death and <5% of patients were reported as experiencing co-infection at admission.

Conclusion: age, vasopressor use in patients with tracheostomy, and systemic coronary disease, heart failure, neoplasia, and COPD, were found to be significantly associated with COVID-19 severity.

La defensa como herramienta de acople: el caso de Argentina frente a Estados Unidos (2015-2019)
Authors: Magnani Ezequiel
Published: July 2022

Los estudios sobre la defensa nacional en Argentina hasta el momento no han incluido en su agenda los aportes de la “escuela de la autonomía”. Considerando que dicha tradición plantea distintas formas que tienen los Estados de vincularse con Estados Unidos (acople/resistencia) y que la defensa es un ámbito gubernamental que incide en dicha vinculación, el presente artículo tiene un doble objetivo: dar cuenta teóricamente de la forma en la que la política de defensa puede contribuir a una estrategia de acople hacia Estados Unidos, e ilustrar empíricamente dicha relación teórica, a partir del análisis de la política de defensa argentina. Se utiliza una metodología cualitativa, tomando como estudio de caso la política de defensa que llevó adelante Argentina durante el período 2015-2019. Se toma como referencia empírica a tres áreas propias de la defensa nacional: la definición de amenazas, la defensa como herramienta de posicionamiento internacional y la forma en que se realiza la adquisición de capacidades militares. Se concluye que el estudio de la política de defensa argentina (2015-2019) permite afirmar que la defensa nacional puede ser utilizada como una herramienta de acople hacia los Estados Unidos.
AbstractStudies on national defense in Argentina have not addressed the contributions of the “escuela de la autonomía”. Considering that this theoretical tradition proposes different ways in which States can enable links with the United States (bandwagon/resistance) and that defense policy is a governmental area that affects that relationship, the article has a double objective: to inquire theoretically about the way in which defense policy can contribute to a bandwagon strategy towards the Unites States and to illustrate empirically this theoretical relationship from the analysis of the Argentine defense policy. A qualitative methodology is used, taking as a case study the defense policy carried out by Argentina during the period 2015-2019 and taking three areas of national defense as an empirical reference: the definition of threats, defense as an international positioning tool, and the way in which military capabilities are acquired. It is concluded that the study of the Argentine defense policy (2015-2019) indicates that national defense can be used as a bandwagoning tool towards the United States.
La estación espacial china en la Patagonia: una aproximación desde el derecho internacional
Authors: Castillo-Argañarás Luis-Fernando
Published: July 2022

El objetivo de este artículo es analizar la cooperación internacional entre Argentina y China sobre la utilización de la estación espacial construida en la Patagonia, en el marco de una asociación estratégica integral. Se realiza un análisis documental, mediante la recolección de datos y una estrategia cualitativa basada en la inducción y deducción. Se concluye que los acuerdos que establecen la estación espacial en el marco de la asociación estratégica son “tratados desiguales”, de la misma naturaleza que los firmados por China en el siglo XIX y principios del XX.

 

Abstract

The objective of this article is to analyze the international cooperation between Argentina and China in relation to the use of the space station built in Patagonia, within the framework of a comprehensive strategic partnership. Documentary analysis is carried out by collecting data and implementing a qualitative strategy based on induction and deduction. It is concluded that the agreements that establish the Space Station within the framework of the strategic association are “unequal treaties” of the same nature as those signed by China in the 19th and early 20th centuries.

Introduction. Combustible cigarette use is associated with an increased risk of several cardiovascular diseases; however, less is known about associations between these cardiovascular conditions and electronic cigarette use.
Methods. This study investigated relationships between electronic and/or combustible cigarette use and diagnoses of cardiovascular diseases using the National Health Interview Survey from 2014, 2016, 2017, and 2018.
Results. Compared to non-users, dual users of electronic and combustible cigarettes had increased likelihood of having prior diagnoses of hypertension (OR 1.660, 95% CI=1.519-1.814), stroke (OR 2.396, 95% CI=2.011-2.855), diabetes mellitus (OR 1.219, 95% CI=1.108-1.341), coronary artery disease (OR 2.211, 95% CI=1.837-2.660), and myocardial infarction (OR 3.839, 95% CI=3.232-4.560). Exclusive use of electronic cigarettes was associated with an increased likelihood of having hypertension compared to non-users (OR 1.244, 95% CI=1.048-1.477).
Conclusions. There was no difference in diagnoses of stroke, diabetes mellitus, coronary artery disease, nor myocardial infarction among exclusive electronic cigarette users compared to non-users; however, these associations could change as young electronic cigarette users with hypertension age, indicating the need for continued research.
El acorde conceptual del animal humano: consideraciones sobre la posibilidad de abordar los conceptos como acordes
Authors: D'Assunção Barros José
Published: July 2022

En este artículo queremos exponer la posibilidad de aproximarnos a la construcción y comprensión de los conceptos (en cualquier campo del saber) a partir de una noción musical: la de acorde. El universo experimentado para esta posibilidad será el del concepto de Ser Humano a partir de su concepción biológica y dirigido, posteriormente, a aspectos antropológicos y filosóficos. El objetivo es demostrar, a partir de este ejemplo, que este procedimiento teórico también es viable para el estudio de otros objetos en los muchos campos de investigación. Para realizar la demostración con el ejemplo elegido, aquí se evoca la taxonomía aceptada por la biología en la actualidad. En cuanto a los aspectos filosóficos de la teoría de conceptos, adoptaremos, como punto de partida, la interacción clásica entre comprensión y extensión de conceptos, considerando que la comprensión de un concepto se configura a partir de varias “notas” que se unen para conformar su significado. La incorporación de una terminología y perspectiva musical al tratamiento de conceptos y su aplicación a diferentes campos como la Biología es la principal originalidad de este trabajo
El gerundio predicativo en español
Authors: Mora-Bustos Armando , Ortiz Villegas Alejandra I. , García Zúñiga H. Antonio
Published: July 2022

El objetivo de este trabajo es describir las predicaciones de gerundio. El aporte que se presenta está orientado al hecho de que la lengua española no solamente dispone como núcleo de una predicación oracional a un verbo flexionado, sino que el gerundio funge como núcleo de una predicación clausal. La predicación de gerundio codifica y expresa los rasgos gramaticales a través de mecanismos particulares; el argumento sujeto (efectuador-agente) está exhibido, generalmente, en una frase nominal ubicada en posición preverbal; el argumento objeto y el argumento objeto-dativo se indexan, a través de clíticos, en el núcleo de la predicación, las frases nominales con las que hacen referencia explicitan las propiedades de los roles temáticos. El sistema de marcación de estas construcciones es mixto: marcación en el dependiente y marcación en el núcleo. Los valores aspectuales y de modo están expresados por la naturaleza léxica de la base del gerundio y por los adjuntos. La variedad de español objeto del estudio es la mexicana, en particular la de la ciudad de México.
“Me dicen negro, pero eso ya no es una molestia para mí”: historias de agencia racial en la escolaridad chilena
Authors: Valoyes-Chávez Luz Edith
Published: July 2022

¿Qué nos dicen las historias de vida sobre la agencia racial de los estudiantes negros en contextos educativos? ¿Qué nos dicen estas historias sobre los límites, desafíos y posibilidades del discurso sobre la inclusión de niños, niñas y jóvenes negros e inmigrantes en la escolaridad? En este artículo de investigación presento las experiencias raciales de Henry y Michelle, dos estudiantes haitianos en el sistema educativo chileno. Para ello se implementaron técnicas de investigación narrativa, evidenciando que, contrario a estudios en los cuales los estudiantes negros son posicionados como receptores pasivos de la violencia racial o como víctimas, Henry y Michelle despliegan una serie de mecanismos emocionales y personales para responder a microagresiones raciales en el sistema educativo. Esta agencia racial les permite enfrentar la marginalización en la clase en una dinámica constante de reconstrucción de sus identidades matemáticas y raciales.

Voces invisibilizadas, voces visibilizadas: hacia un diálogo intercultural entre el saber misak y el conocimiento global
Authors: Fayad sierra Javier alfredo , Tunubalá-Velasco Gerardo
Published: July 2022

En este artículo de reflexión se retoman diferentes elementos de investigaciones sobre racialismos en la educación y se plantean aspectos de interés sobre la educación en el contexto del pueblo misak. El proceso de dominación se basa en un mecanismo racialista y dominador que invisibiliza intencionadamente a los pueblos indígenas, quienesplantean una salida desde el autorreconocimiento, la pervivencia y la re-existencia como pueblo. En Colombia se caracteriza el tema indígena por la continuidad de la concepción racialista del poder, que se manifiesta en la manera como los Gobiernos mantienen una mentalidad colonial ante los territorios indígenas: primero, en la hegemonía conservadora, se expide la Ley 89 de 1890, la cual entrega la educación a las órdenes religiosascon la idea de civilizar al “salvaje”, mientras que en la República liberal del siglo xx se concibe lo mestizo como el ideal demográfico, negando las opciones de lo indígena. Antes de la Constitución de 1991 se consideraban a los indígenas como salvajes, premodernos y subalternos; luego emergieron condiciones posibles de reconocimientopara lograr que los diferentes pueblos definan y afirmen los elementos de recuperación territorial, cultural y de autoridad que ya venían implementando desde los años setenta y ochenta. En los aspectos educativos es de gran interés la forma como se responde desde adentro de los pueblos a la violencia epistémica que desconoce las bases culturales y pedagógicas del conocimiento como pueblo, donde el pueblo misak replica a esta visión racialista construyendo una propuesta educativa propia que recupera epistemes propias de su cultura.
Sobre las obras de este número
Authors: Krebs Patricia
Published: July 2022

Las obras aquí seleccionadas pertenecen a diferentes series creadas entre 2009 y 2021. En mi serie “Los Otros” hay siempre un personaje fuera de lugar que pelea por su derecho a ser quien es. Este tema es importantísimo porque como seres sociales necesitamos sentir que pertenecemos, pero mi pregunta es ¿cuánto de ese pertenecer nos roba de nuestra propia complejidad como individuos? En la colección “A La Luz de Lo Oscuro” se confrontan nociones arbitrarias de lo bueno y lo malo, lo bello y lo monstruoso: el encuentro entre la civilización europea con la americana y la africana, la contraposición de lo ‘civilizado’ y lo ‘primitivo’, la colonización cultural, religiosa y económica. En “De Hombres, Mujeres y Otros”, contrasto la idea de que lo masculino es fuerte y lo femenino es débil. En “Poder” me cuestiono qué características de nuestras sociedades nos quitan poder y cuáles pueden empoderarnos. La imagen “Creciendo Juntos es de mi serie más reciente “Otro Cuerpo”, y para mí sintetiza lo dicho anteriormente: ¿podemos construir juntos algo más bello desde nuestras diferencias en lugar de que éstas nos separen?
El acompañamiento formativo de las semillas de vida con los y las sabedoras nasas
Authors: Useda Sánchez Hamilton , Tumbo García Berta Lucy , Ramos Pacho Abelardo
Published: July 2022

La realidad en la que estamos nos da posibilidades para afrontarla caminando junto a los senderos iniciados por los sabedores ancestrales de miles de pueblos o mediante una estrecha, plana y limpia trocha construida por unos pocos que gobiernan el mundo, dirigiéndolo a una posible destrucción de toda vida humana. Desde uno de esos saberes en resistencia, compartimos este artículo que recoge algunos elementos del camino recorrido entre las sabedoras ancestrales del pueblo Nasa Sa’th Tama Kiwe junto con las semillas de vida de este Territorio Ancestral. Este camino fue realizado en comunión con las energías cósmicas y los espíritus de la Madre Tierra, pero complementados en tensión con aquellas familias que están perdiendo la posibilidad de formar con autonomía a las niñas y niños que inician su ciclo de vida en el Territorio. En este caminar nos hemos encontrado para sentarnos junto al fuego y mascando coca para compartir la palabra, reflexionar y proyectar las maneras de acompañar la crianza de nuestras semillas de vida desde los saberes ancestrales y esos sentipensamientos que pretendemos compartir en este texto.
