Authors: Altamirano Galván Sandra Guadalupe
Published: March 2021

La presente investigación se enmarca en un estudio para determinar el perfil de alfabetización mediática de estudiantes y docentes de educación superior en una facultad de Artes de una universidad pública de Nuevo León. El abordaje metodológico se gestó desde la Investigación Basada en Diseño (IBD), a partir del análisis de teorías, pensamientos y estudios existentes en el tema que incluye instrumentos de recolección de datos con enfoque cuantitativo y cualitativo, a través de las cuales se determinó dicho perfil. Los resultados muestran mayores fortalezas en las competencias de tecnología y políticas TIC, pero también mayores debilidades en las competencias de información, conocimiento y comunicación, por lo que se hace evidente la necesidad de alfabetizar mediáticamente a los protagonistas de la educación en estos tiempos en los que el uso de la tecnología se presenta como un requisito irremplazable de la enseñanza-aprendizaje.

Authors: Lindo De Las Salas Mónica
Published: March 2021

Identificar las representaciones sociales de las prácticas formativas llevadas a cabo en el Carnaval de Barranquilla y la relación que éstas tienen con la salvaguardia de las tradiciones, se constituyen en el objetivo principal de la presente investigación. En el proceso metodológico se toma como población a la Danza del Congo por ser una de las más antiguas del Carnaval. Se hace uso de la etnografía y la teoría de las representaciones sociales para explicar la forma en que se transmiten las tradiciones a partir de la información de los sujetos, el campo de representación, la actitud y los mecanismos de objetivación y anclaje. La resistencia a la apropiación simbólica de lo tradicional y la tensión entre los intereses particulares de los jóvenes, los antecesores y la institucionalidad son, entre otras, las informaciones implícitas en las representaciones generadas en el desarrollo de las prácticas formativas de la Danza del Congo.

Published: March 2021

Aim. To study the results of simultaneous abdominoplasty and laparoscopic ventral hernia alloplasty in patients with obesity. Material and Methods. Simultaneous adbominoplasty and laparoscopic hernioplasty for ventral hernias were performed in 31 patients. The mean age of the patients was 53.7±6.5 (95% CI 51.3; 56.0). All patients were diagnosed as obese (body mass index more than 30 kg/m2). Incisional hernia was the main indication for surgery in the majority of patients - 20 (64,5%); in 11 (35%) cases a primary hernia of median localization was detected. Immediate and long-term results of surgical interventions were studied. Results and Discussion. In the postoperative period after drainage removal accumulations of fluid (seromas) were revealed in 9 (29%) patients using ultrasound investigation; in 2 cases they were evacuated by puncture. In one case, a marginal necrosis of the skin around the formed umbilicus occurred (healing by secondary tension); in another, lower lobe pneumonia was diagnosed (eliminated by antibiotic therapy). The average length of hospital stay was 7.3±1.4 (95% CI 6.8; 7.9) days, 6-8 days in most cases. Only two patients were hospitalized for more than 8 days due to postoperative complications. No recurrences of hernias were registered at follow-up examination 1-3 years later; good cosmetic results were achieved. Conclusions. In patients with ventral hernias with obesity and fat apron it is advisable to perform simultaneous intervention - abdominoplasty and allogernioplasty. It is advisable to perform alloplasty of ventral hernias with simultaneous abdominoplasty via laparoscopic access according to IPOM technology with the use of mesh endoprosthesis with antiadhesive coating. Simultaneous abdominoplasty causes an increase in the frequency of seromas in the postoperative period, but it does not increase the duration of hospital treatment. Simultaneous surgeries allow achieving good cosmetic results and do not increase the incidence of hernia recurrence.

Scientific basis for design low-speed synchronous permanent magnet generators for wind power plants
Authors:   Omsk State Technical University, Tatevosyan A. A.
Published: March 2021

In this paper, the scientific basis for designing wind power plants (WPP) with low-speed synchronous generators on permanent magnets (SGPM) is understood as a system of scientific knowledge that forms the theoretical basis for the practice of designing a complex object, such as WPP consisting of interconnected equipment and structures designed to convert wind energy into electrical energy. Currently, the development of advanced WPP designs is receiving increased attention around the world. For example, in the Russian Federation, a promising direction is the creation of Autonomous WPP with low-speed medium- and low- power SGPMs that have the maximum range of applications by type of activity and climate zones throughout the territory. However, engineering approaches to the design of individual components of the WPP indicate the difficulties of developing a scientifically based methodology for optimizing the parameters of the WPP as a whole taking into account the mutual influence of individual components on each other. At the same time, the methodology for optimizing the parameters of WPP is understood as a tool for the scientific basis of design, which takes into account quality indicators and optimality criteria, energy and technical characteristics, as well as design stages with the results of preliminary and verification calculations. For the stage of verification calculations of VEU parameters, the scientific basis of design is determined by the construction of mathematical models and their research using application software packages for PCs, while for the stage of preliminary calculations, the development of analytical methods of analysis is important. This article discusses the scientific basis for designing wind turbines at the stage of preliminary calculations, formulated the problem of optimizing the parameters of low-speed WPP, proposed equations for the relationship of design parameters with the energy performance of wind turbines, providing the maximum efficiency of synchronous generators, taking into account the specified technical conditions

The paper investigates the existing mathematical models of insulation destruction. It has been determined that most of the models for assessing the residual life of insulation are based on models of thermal and thermo-oxidative destruction of insulation materials. Currently, solid dielectrics are gaining popularity, including crosslinked polyethylene, PVC, ethylene-propylene rubber, and others. In such dielectrics, it is possible to estimate the residual life in the short term. This possibility and necessity is due to the possibility of growth of tree defects under the influence of partial discharges. The article describes the proposed mathematical model for assessing the residual resource of insulation by modeling the growth of a defect. To take into account the influence of random variables, the model uses the Weibull distribution. The model assumes the division of the insulation thickness into some areas, each of which is destroyed independently of the others. The destruction of these areas occurs when partial discharges occur with certain energy sufficient to destroy the material. Insulation failure is predicted using the least squares method. The results obtained can be useful in assessing the residual life of insulating materials and in conducting research in this area

The article discusses the features of the inertial explosion of metal products and the prevention of its occurrence during its impact introduction of a metal penetrator into the ground of celestial bodies. The possibility of an inertial explosion in metal penetrators is determined when calculating the critical overload of the Gcr that exceeds a certain threshold value for each metal. These values are determined for a number of alloys and high-purity metals widely used in rocket and space technology for Earth and space temperatures. The features of reducing the critical overload threshold of the Gcr for space conditions at cryogenic temperatures and ways to prevent an inertial explosion are discussed

Health and Family Communication: Exploring Concept and Issues
Authors: Eko Hero  , Dini Sundari
Published: March 2021

The phenomenon of early age marriage has occurred in many places over the world including in Indonesia. What is more, the maternal mortality rate and other risks of health reproductive had been also increased. Numerous of argumentations that the pregnancy at a young age will create a higher chance of females having a bunch of children and a higher risk of death of the mother and child. Likewise, analyzing important issues regarding marriage at a young age is very important to provide a deep scientific understanding. Through a qualitative approach, this study aims to explore the conceptual issues about health communication which involves reproductive health, negotiation, early-age marriage, and family communication. Health communication is the role of communication to disseminate health information in the form of communication with patients, family, and community. Reproductive health is about all matters related to a reproductive system including its functions and processes. Negotiation concerns the interactive process done to reach an agreement that involves two or more people who have different perspectives and willing to reach the same resolution together.    The early-age marriage is a formal or non-formal marriage done below 18 years of age. Family communication is a communication activity done in a family in which a process of exchanging meaning includes delivering emotion among its members.
Analysis of Feminist Principels in The Da’wah Agenda of Gender Equality
Authors: Nasution Karimuddin , Mohd Saad Mohd Faizulamri
Published: March 2021

One of the da’wah that is quite intense this time in the media is the da'wah feminist group for gender equality. The main mission of Muslim feminists is to equalize men and women in all matters. To fulfill this mission, they always lay down the basic principles of gender equality taken from the Koran and the hadith, then they will interpret textually. Only after that was reached did they interpret the Koran and the Hadith in accordance with their wishes. If it contradicts the verses that place men and women differently they will usually deny it on the grounds that it conflicts with the principle of gender equality. This study aims to analyze the principles of gender equality in the gender equality da’wah agenda. Methodology of this study was qualitative using document analysis. Data collection was done through library research. The data were analyzed using descriptive, comparative and critique. The findings showed that the feminists made Qur’anic verses as the principles of gender equality. The principles are men and women alike servants, men and women alike caliphs, men and women alike accept the covenant when they are in the womb, Adam and Eve are both engaged in transgression in heaven until had been sent to the earth, men and women equally have potential in every aspect of life. The Qur’anic verses that are made as the basis of the principles of gender equality seem to be over-implemented. The tafsir scholars do not explain the verses in the context of male and female relationships. The implication of this study is that Muslims are encouraged to refer to the interpretation of the authority scholars who have been recognized by the Muslim’s world, therefore is no mistakes in understanding the verses of the Qur’an.  It is also expected to give a real understanding of the relationship between men and women in the Qur’an
STOUT: SMILES to IUPAC Names Using Neural Machine Translation
Authors: Rajan Kohulan , Zielesny Achim , Steinbeck Christoph
Published: March 2021

Chemical compounds can be identified through a graphical depiction, a suitable string representation, or a chemical name. A universally accepted naming scheme for chemistry was established by the International Union of Pure and Applied Chemistry (IUPAC) based on a set of rules. Due to the complexity of this rule set a correct chemical name assignment remains challenging for human beings and there are only a few rule-based cheminformatics toolkits available that support this task in an automated manner. Here we present STOUT (SMILES-TO-IUPAC-name translator), a deep-learning neural machine translation approach to generate the IUPAC name for a given molecule from its SMILES string as well as the reverse translation, i.e., predicting the SMILES string from the IUPAC name. The open system demonstrates a test accuracy of about 90% correct predictions, also incorrect predictions show a remarkable similarity between true and predicted compounds.

Tumor hypoxia is associated with therapy resistance and poor patient prognosis. Hypoxia-activated prodrugs, designed to selectively target hypoxic cells while sparing normal tissue, represent a promising treatment strategy. We report the pre-clinical efficacy of 1-methyl-2-nitroimidazole panobinostat (NI-Pano, CH-03), a novel bioreductive version of the clinically used lysine deacetylase inhibitor, panobinostat. NI-Pano was stable in normoxic (21% oxygen) conditions and underwent NADPH-CYP-mediated enzymatic bioreduction to release panobinostat in hypoxia (<0.1% oxygen). Treatment of cells grown in both 2D and 3D with NI-Pano increased acetylation of histone H3 at lysine 9, induced apoptosis and decreased clonogenic survival. Importantly, NI-Pano exhibited growth delay effects as a single agent in tumor xenografts. Pharmacokinetic analysis confirmed the presence of sub- micromolar concentrations of panobinostat in hypoxic mouse xenografts, but not in circulating plasma or kidneys. Together, our preclinical results provide a strong mechanistic rationale for the clinical development of NI-Pano for selective targeting of hypoxic tumors.
The Relation Between Ejection Mechanism and Ion Abundance in the Electric Double Layer of Drops
Authors: Kwan Victor , O'Dwyer Ryan , Laur David , Tan Jiahua , Consta Styliani
Published: March 2021

Charged droplets have been associated with distinct chemical reactivity. It is assumed that the composition of the surface layer plays a critical role in enhancing the reaction rates in the droplets relative to their bulk counterparts. We use atomistic modeling to relate the localization of the ions in the surface layer to their ejection propensity. We find that

the ion ejection takes place via a two-stage process. Firstly, a conical protrusion emerges as a result of a global droplet deformation that is insensitive to the locations of single ions. The ions are subsequently ejected as they enter the conical regions. The study provides mechanistic insight into the

ion-evaporation mechanism, which can be used to revise the commonly used ion-evaporation models. We argue that atomistic molecular dynamics simulations of minute nano-drops, do not sufficiently distinguish the ion-evaporation mechanism from a Rayleigh fission. We explain mass spectrometry data on the charge state of small globular proteins and the existence of super-charged droplet states (above the Rayleigh limit) that have been detected in experiments.

Published: March 2021

We report for the very first time the self-assembly of Fmoc variant 2-(9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(tert-butoxy)butanoic acid of threonine (Fmoc-Thr(tbu)-OH) and of serine (Fmoc-Ser(tbu)-OH. The self-assembled structure formation of Fmoc variants of threonine and serine were examined under varying concentration and temperature conditions..Our studies reveal that the self-assembled structures formed by Fmoc-Thr(tbu)-OH and Fmoc-Ser(tbu)-OH reveal morphological transitions at the supramolecular level as we alter its concentration and temperature. Fmoc-Thr(tbu)-OH self-assembles to sphere at lower concentration which changes to dumb-bell shapes at higher concentration under room temperature conditions. When the solution at lower concentration is heated the spheres changes to rods while the dumb bell shapes at higher concentrations change to elongated dumb-bell-rod like morphologies. Fmoc-Ser(tbu)-OH on the other hand give flower like morphologies at lower concentration which changes to long rods at higher concentration. On heating at higher temperature 70 οC flower-like structures change to small rods while the long rods obtained at higher concentration changes to big flower-like structures. The controlled morphological changes noted in the modified single amino acids is very interesting and pave the way for the design of novel self-assembled architectures for applications in material science and nanotechnology.
Ferromagnetic–Antiferromagnetic Coupling Core–Shell Nanoparticles with Spin Conservation for Water Oxidation

Published: March 2021

Rational design of active oxygen evolution reaction (OER) catalysts is critical for the overall efficiency of water electrolysis. OER reactants and products’ differing spin states is one of causes to slow OER kinetics. Thus, spin conservation plays a crucial role in enhancing OER performance. In this work, we design ferromagnetic (FM)–antiferromagnetic (AFM) Fe3O4@Ni(OH)2 core–shell catalysts. The interfacial FM–AFM coupling of these catalysts facilitates selective removal of electrons with spin direction opposing the magnetic moment of FM core, improving OER kinetics. The shell thickness is found critical in retaining the coupling effect for OER enhancement. The magnetic domain structure of the FM core also plays a critical role. With a multiple domain core, the applied magnetic field aligns the magnetic domains, optimising the electron transport process. A significant enhancement of OER activity is observed for the multiple domain core catalysts. With a single domain FM core with ordered magnetic dipoles, the spin-selective electron transport with minimal scattering is facilitated even without an applied magnetic field. We therefore draw a magnetism/OER activity model that depends on two main parameters: interfacial spin coupling and domain structure. Our findings provide new design principles for active OER catalysts.
An Analysis of Recent BLYP and PBE-Based Range-Separated Double-Hybrid Density Functional Approximations for Main-Group Thermochemistry, Kinetics and Noncovalent Interactions
Authors: Najibi Asim , Casanova Paez Marcos , Goerigk Lars
Published: March 2021

We investigate the effects of range separation of the exchange energy on electronic ground-state properties for recently published double-hybrid density functionals (DHDFs) with the extensive GMTKN55 database for general main-group thermochemistry, kinetics and noncovalent interactions. We include the semi-empirical range-separated DHDFs ωB2PLYP and ωB2GP-PLYP developed by our group for excitation energies, together with their ground-state-parametrized variants, which we denote herein as ωB2PLYP18 and ωB2GP-PLYP18. We also include the non-empirical range-separated DHDFs RSX-0DH and RSX-QIDH. For all six DHDFs, damping parameters for the DFT-D3 dispersion correction (and for its DFT-D4 variant) are presented. We comment on when the range-separated functionals can be more beneficial than their global counterparts, and conclude that range separation alone is no guarantee for overall improved results. We observe that the BLYP-based functionals generally outperform the PBE-based functionals. We finally note that the best-performing double-hybrid density functionals for GMTKN55 are still the semi-empirical range-separated double hybrids ωDSD3-PBEP86-D4 and ωDSD72-PBEP86-D4, the former of which includes a third-order perturbative correlation term in addition to the more conventional second- order perturbation that DHDFs are based upon.
Electrochemically Driven Stereoselective Approach to syn-1,2-Diol Derivatives from Vinylarenes and DMF
Authors: Chung Da Sol , Park Steve H , Lee Sang-gi , Kim Hyunwoo
Published: March 2021

We have developed an electrochemically driven strategy for the stereoselective synthesis of protected syn-1,2-diols from vinylarenes with N,N-dimethylformamide (DMF). The newly developed system obviates the need for transition metal catalysts or external oxidizing agents, thus providing an operationally simple and efficient route to an array of protected syn-1,2-diols in a single step. This reaction proceeds via an electrooxidation of olefin, followed by a nucleophilic attack of DMF. Subsequent oxidation and nucleophilic capture of the generated carbocation with a trifluoroacetate ion is proposed, which gives rise predominantly to a syn-diastereoselectivity upon the second nucleophilic attack of DMF.

Mapping the micro-proteome of the nuclear lamina and lamina-associated domains
Authors: Wong Xianrong , Cutler Jevon A , Hoskins Victoria E , Gordon Molly , Madugundu Anil K , Pandey Akhilesh , Reddy Karen L
Published: March 2021

The nuclear lamina is a proteinaceous network of filaments that provide both structural and gene regulatory functions by tethering proteins and large domains of DNA, the so-called lamina-associated domains (LADs), to the periphery of the nucleus. LADs are a large fraction of the mammalian genome that are repressed, in part, by their association to the nuclear periphery. The genesis and maintenance of LADs is poorly understood as are the proteins that participate in these functions. In an effort to identify proteins that reside at the nuclear periphery and potentially interact with LADs, we have taken a two-pronged approach. First, we have undertaken an interactome analysis of the inner nuclear membrane bound LAP2β to further characterize the nuclear lamina proteome. To accomplish this, we have leveraged the BioID system, which previously has been successfully used to characterize the nuclear lamina proteome. Second, we have established a system to identify proteins that bind to LADs by developing a chromatin-directed BioID system. We combined the BioID system with the m6A-tracer system which binds to LADs in live cells to identify both LAD proximal and nuclear lamina proteins. In combining these datasets, we have further characterized the protein network at the nuclear lamina, identified putative LAD proximal proteins and found several proteins that appear to interface with both micro-proteomes. Importantly, several proteins essential for LAD function, including heterochromatin regulating proteins related to H3K9 methylation, were identified in this study.
"... about as austere as a Dior gown ...": New Zealand architecture in the 1960s
Authors: McCarthy Christine
Published: March 2021

Peter Middleton's 1964 description of Hoogerburg Scott's Futuna Chapel (1958-1960) as being "about as austere as a Dior gown and as comforting as a hair shirt ... [but] at least it's a meaningful statement" points to a sense of complexity and contradiction present in the architecture of the 1960s. The decade which began with Futuna's completion, ends shortly after its recognition with an NZIA Gold Medal Award in 1968. The significance of the building weaves through the full length of the decade.
A Final Formality: Three Modernist Pavilion Houses of the early 1960s
Authors: Dudding Michael
Published: March 2021

The Beard, Alington, and Mackay houses represent the endpoint of a direction in New Zealand domestic architecture that was both internationalist and based within the realities of local house building in the mid-twentieth century. Imi Porsolt, while reviewing Stephanie Bonny and Marilyn Reynolds'book Living with 50 Architects in 1980, specifically points to the Alington house as the final formalisation of this purist trend. Porsolt's review provides an historical subtext to Living with 50 Architects that opposes the "altogether austere style" of the pavilion with the vernacularism of what is best described as the "elegant shed" tradition of New Zealand house design. More elegant than the elegant shed, these pavilions reveal something of a "blind spot" in New Zealand's architectural history – aside from the inclusion of the Beard and Alington houses in Living with 50 Architects,they have not appeared in any of the canon-forming historical surveys such as Mitchell and Chaplin's The Elegant Shed or Shaw's A History of New Zealand Architecture. The Mackay house also has not featured until its recent appearance in Lloyd Jenkins' At Home: A Century of New Zealand Design. This paper uses Porsolt's view as a useful starting point from which to consider the relationship that exists between the Beard, Alington, and Mackay houses, and their place in the development of New Zealand's domestic architecture during the 1960s.

This piece of research reflections addresses an important part of parents’ training and professional development, which unfortunately was overlooked previously. After reviewing opinion papers, program descriptions, theoretical frameworks, empirical studies, literature reviews on parental involvement, the study found a substantial gap in research, programs, and practice. The literature on parents’ involvement and its barriers, the study presents epistemological foundations for the overlooked part of parents’ training. The study recommends Internet Coupled Information and Communication Technologies (ICICTs) based parents’ training with synchronous and asynchronous modes providing quality content for enhancing parents’ knowledge, skills, and competence in educational aspects. These trainings on educational aspects target to create common knowledge constructs that can facilitate parents and teachers to establish complementary communication; leading to effective parental involvement beneficial for children and schools in the effective implementation of the whole-child approach. As parents' knowledge, skills, and competencies in educational aspects grow, it will increase their involvement, assistance, and interaction with their children and the school. Enhanced technology skills can also help parents overcome barriers that hindered their involvement in children education.

Background: There is currently a growing concern to conduct health-related quality of life (HRQOL) studies among people with epilepsy in low- and middle-income countries, as most data have been derived from high-income countries in North America and Europe. Aims: To translate, adapt and validate the Moroccan Arabic version of the QOL Inventory in Epilepsy-31 (MA-QOLIE-31) to evaluate HRQOL predictors in the Moroccan population with epilepsy. Methods: Adaptation and validation of QOLIE-31 were performed in July 2018 among 118 patients with epilepsy in the Fez–Meknes region. The test was translated, adapted and validated into Arabic according to the Streiner & Norman recommendations. Acceptability, reliability, central tendency and validity of the QOLIE-31 were assessed. Results: The acceptability and reproducibility were satisfactory and the internal consistency was strong (Cronbach α = 0.993). The mean (standard deviation) global score of QOL in the MA-QOLIE-31 was 68 (22.16). The scores in the subscales were 51 (36.88) for seizures worry, 48.86 (25.44) for overall QOL, 45.60 (26.73) for well-being, 41.28 (25.37) for energy and fatigue, 47.55 (28.33) for cognitive function, 66.83 (39.49) for medication effects and 52.44 (30.26) for social functioning. Conclusions: The global score of QOL in Moroccan patients with epilepsy is similar to that in patients in low and middle-income countries. MA-QOLIE-31 will facilitate further studies in HRQOL in Morocco and Arabic-speaking countries.
