Ensemble Generalized Kohn-Sham Theory: The Good, the Bad, and the Ugly
Authors: Gould Tim , Kronik Leeor
Published: December 2020

Two important extensions of Kohn-Sham (KS) theory are generalized KS theory and ensemble KS theory. The former allows for non-multiplicative potential operators and greatly facilitates practical calculations with advanced, orbital-dependent functionals. The latter allows for quantum ensembles and enables the treatment of, e.g., open systems and excited states. Here, we combine the two extensions, both formally and practically, first via an exact yet complicated formalism, then via a computationally tractable variant that involves a controlled approximation of ensemble "ghost interactions" by means of an iterative algorithm. The resulting formalism is illustrated using selected examples. This opens the door to the application of generalized KS theory in more challenging quantum scenarios and to the improvement of ensemble theories for the purpose of practical and accurate calculations.
On the Common Ground of Thermodynamics and Kinetics: How to Pin Down Overpotential to Reversible Metal Hydride Formation and the Complete Ideal Gas Theory of Reversible Chemical Hydrogen Storage
Authors: Pawelke Roland Hermann
Published: December 2020

Ti-doped NaAlH4 requires at 125 °C for [AlH4] formation more than twice the equilibrium pressure; while it is straightforward to relate this conditional surplus in hydrogenation pressure respective chemical potential to kinetic hindrance, it appears strange that this matter has not been duly theoretically addressed in literature to this day. The interest in identifying such overpotentials is not of purely academic interest but touches a problem of very practical significance as the maximum applied pressure is an important threshold to metal hydride tank design. A theory-based tool would be a resource-efficient complement or even alternative to PCI measurements. This paper tracks the formation overpotential issue down to its root and outlines a simple yet accurate general method based on Arrhenius and van’t Hoff data. Rather unexpectedly, the result is also the final missing piece towards a comprehensive understanding of reversible chemical hydrogen storage with regard to attainable hydrogen storage capacity.

Acute respiratory viral infections (ARVI) are an urgent problem for doctors of various specialties. Occupying a leading position in terms of accessibility to medical institutions, ARVI inflict significant economic damage due to the cost of drugs, as well as temporary disability of patients. The cause of ARVI can be the ingress of more than 200 different viral pathogens on the mucous membrane of the upper respiratory tract and, as a consequence, a decrease in its protective abilities with subsequent damage and the development of local and general inflammatory symptoms. The manifestations of acute respiratory viral infections are diverse, on the part of the ENT organs it is most often rhinorrhea, as well as discomfort, perspiration, sore throat, nasal congestion, decreased or loss of smell. For general intoxication syndrome in ARVI, severe headache, pain in muscles and joints, as well as general malaise and fever with an increase in body temperature of varying severity are characteristic. At the moment, there is no universal etiotropic drug for the treatment of acute respiratory viral infections, and therefore pre-ference is given to symptomatic treatment. The use of symptomatic drugs is aimed at relieving such symptoms as pain of various localization and hyperthermia. The main drugs for such therapy are nonsteroidal anti-inflammatory drugs, which can be used as monotherapy and in combination therapy.

INTEGRATED CRYPTOGRAPHICAL ACCESS CONTROL OVER NETWORK PROJECT
Authors: Makeri Yakubu Ajiji
Published: December 2020

Cryptanalysis is a new ID-based encryption scheme proposed by Meshram. I found a method for factor N, where N is the parameter proposed by Meshram. We also provide a method for retrieving the Secret Master key for Mayshram’s ID-based encryption scheme. Identity-based (ID-based) cryptography is very useful because it simplifies certificate management in public-key cryptocurrency. For the design of the Integrated File Level Cryptographic Access Control (IFLCAC) system, it makes file security much easier for the end-user. This system combines the advantages of traditional file-level cryptography and full-disc cryptography systems, making it safe and easy to use. We first look at existing file cryptography systems, compare them to two, and then describe the interactions between components and components of the integrated file-level cryptographic access control system. Because its defense relies on the difficulty of discrete logarithmic and integer factor problems, it proves that his scheme is safe against favorable select-plain invasion. We show that this new ID-based encryption scheme is not secure by introducing a method to retrieve the secret master key.

LINKCALCULATOR – AN EFFICIENT LINK-BASED PHISHING DETECTION TOOL
Authors: Abiodun Orunsolu , A.S Sodiya , S.O Kareem
Published: December 2020

The problem of phishing attacks continues to demand new solutions as existing solutions are limited by various challenges such as high computational requirements, zero-day attacks, needs for updates, complex ruled-based, etc. Besides, the emerging mobile market demands simple solutions to phishing due to several factors such as memory, fragmentation, etc. In response to the above challenges, a simple anti-phishing tool called LinkCalculator is presented. The proposed LinkCalculator anti-phishing scheme is based on an algorithm designed to extract link characteristics from loading URLs to determine their legitimacy. Unlike the other link-based extraction approaches, the proposed approach introduced the concept of weight to represent the different links found in a URL. This is because certain link information within parsed webpages or requests is sufficient to classify them as phishing without loss of generality. The approach is experimented using a dataset of 300 instances consisting of 150 legitimate URLs and 150 phishing URLs from openly-available research datasets. The experimental results indicate a significance performance of 100%. True Negative Rate and 0.00% False Positive Rate for legitimate instances and True Positive Rate of 96.67% with 0.03 % False Negative Rate for phishing instances which indicate that the approach offers a more efficient lightweight approach to phishing detection.

Antiperiodic Boundary Value Problem for a Semilinear Differential Equation of Fractional Order
Authors:   Voronezh State University of Engineering Technologies, Petrosyan G. G.
Published: December 2020

The present paper is concerned with an antiperiodic boundary value problem for a semilinear differential equation with Caputo fractional derivative of order q ∈ (1, 2) considered in a separable Banach space. To prove the existence of a solution to our problem, we construct the Green’s function corresponding to the problem employing the theory of fractional analysis and properties of the Mittag-Leffler function . Then, we reduce the original problem to the problem on existence of fixed points of a resolving integral operator. To prove the existence of fixed points of this operator we investigate its properties based on topological degree theory for condensing mappings and use a generalized B.N. Sadovskii-type fixed point theorem.
On Solvability in the Class of Distributions of Degenerate Integro-Differential Equations in Banach Spaces
Authors:   Irkutsk State University, Falaleev M. V.
Published: December 2020

The paper considers a new approach to constructing generalized solutions of degenerate integro-differential equations convolution type in Banach spaces. The principal idea of the method proposed implies the refusal of the condition of existence of the full Jordan set for the Fredholm operator of the higher derivative with respect to the operator bundle formed by the rest of operator coefficients of the differential part and by the operator kernel of the integral component of the equation. The conditions are superimposed upon the values of the operator function specially constructed on the basis elements of the Fredholm operator kernel. Under such an approach, the differential part of the equation may include not only the higher derivative but also any combination lower derivatives, what allows one to consider the convolution integral-differential equations from universal positions, without any special account of the structure of the structure of the operator bundle. The method proposed represents a form of generalization of the technique based on the application of Jordan sets of Fredholm operators, and in the case of existence of the latter the method coincides with this technique. The generalized solutions are constructed in the form of a convolution of the fundamental operator function, which corresponds to the equation under investigation, and a function, which includes the right-hand side of the equation and the initial data. The conditions, under which such a generalized solution does not contain any singular component, and the regular component converts the initial equation into an identity and satisfies the initial data, and the result will provide for the resolvability of the initial problem in the class of functions of characterized by the respective smoothness. In this case, the generalized solution constructed will be classical. The theorem on the form of fundamental operator function has been proved, the abstract results have been illustrated via examples of initialboundary value problems of applied character from the theory electromagnetic fields, the theory of oscillations in visco-elastic media, the theory of vibrations of thermal-elastic plates.

These situations result from the improper use of the soil in the low course of the river, which is accelerating erosion processes to various degrees, resulting in economic losses and in the risk of desertification. Pedodiversidade e degradação ambiental no baixo curso do rio Acaraú, Ceará, Nordeste do Brasil R E S U M OO presente trabalho analisa a pedodiversidade que caracteriza a área do baixo curso do Rio Acaraú, situado no Noroeste do Estado do Ceará, Nordeste do Brasil, a partir da análise de perfis de solo realizados em campo, e da analise granulométrica, química e mineralógica de amostras dos solos em laboratório. Fez-se uma atualização da tipologia dos solos na área de pesquisa, bem como a identificação de características físicas que indicam a ocorrência de processos de degradação ambiental na área. Essas situações resultam do uso inadequado do solo no baixo curso do rio, o qual está acelerando processos de erosão em vários graus, resultando em perdas econômicas e risco de desertificação.Palavras-chave: Pedodiversidade, Degradação Ambiental, Rio Acaraú, Nordeste do Brasil.
Jesucristo nos llama: la resurrección como acto de fe
Authors:   OAR, Arenas Molina Enrique
Published: December 2020

El objetivo en este texto es presentar la experiencia de la resurrección, el hecho o el acontecimiento, suponiendo los datos de los evangelios y las reflexiones de varios teólogos; se busca, con base en estos elementos, realizar una pastoral catequética que ayude a los cristianos a hacer de la resurrección el fundamento de sus vidas. Son muchos los interrogantes que se presentan en el momento de afrontar la realidad misma de la resurrección y de los que los fieles deben ir tomando consciencia cada vez más plena, sabiendo que la resurrección se hace presente en la vida sacramental que el señor Jesús instituyó en la Iglesia y para comunicar su vida mediante el Espíritu Santo. Aunque el tema de la resurrección es suficiente extenso, lo presentaremos mediante tres capítulos: una valoración teológica, una reflexión pastoral y unas conclusiones. Estos capítulos facilitan de un modo pastoral catequético ese gran acontecimiento de la resurrección de Jesucristo.
Aproximación al concepto de sustentabilidad ambiental urbana. Saberes locales en la construcción de políticas públicas
Authors:   Universitaria Agustiniana, Duquino Rojas Luis Gabriel , Vinasco Ñustes Fabio ,   Universitaria Agustiniana
Published: December 2020

Este capítulo recoge reflexiones que buscan consolidar un debate teórico que afiance el concepto de sustentabilidad ambiental urbana. Tal disertación se construye desde un enfoque crítico y de análisis de la retórica dominante del desarrollo sostenible, creando unas bases discursivas que se contraponen a un pensamiento decolonial estructurado desde el Sur Global. El capítulo contribuye al corpus de los estudios que se presentan como alternativas a las propuestas desarrollistas; hace avances para superar las miradas esquemáticas, netamente economicistas; y reconoce la estructura que en esta dirección se ha consolidado en las últimas décadas en Latinoamérica, donde hay un conocimiento endógeno conectado a un conocimiento ancestral puesto en valor.
Previsiones, descripciones y propuestas de la economía ecológica contra el cambio climático
Authors:   Universitaria Agustiniana, Aguilera-Prado Marco
Published: December 2020

Este capítulo descompone tres modelos de la economía ecológica y sus acciones contra el cambio climático mediante un marco analítico que identifica sus visiones preanalíticas, sus derroteros analítico-descriptivos y los aspectos propositivos de cada uno. Como resultados más significativos se resalta que: a) existen marcadas diferencias en las visiones preanalíticas con respecto a la economía convencional; b) los modelos analizados reconocen las relaciones entre humanos y naturaleza como criterio de formulación; c) existen dificultades para expresar los modelos en estructuras funcionales formales y d) las acciones contra el cambio climático deben pasar por la concepción de los medios y fines de la sociedad. El capítulo concluye que desde la economía ecológica es posible explicar el cambio climático como resultado de las relaciones entre sociedad y naturaleza, y las acciones alternativas que propone contemplan esas relaciones. También se pone de manifiesto la necesidad de conceptualizaciones diferentes para la vida, la sociedad, y sus medios y fines.
Medición de la sustentabilidad ambiental urbana: una propuesta de adaptación de los índices de calidad ambiental al entorno de las ciudades intermedias
Authors:   Universidad Nacional del Sur, London Silvia , Zilio Mariana ,   Universidad Nacional del Sur
Published: December 2020

Este capítulo analiza los componentes de los indicadores de desempeño ambiental e indaga sobre su adaptación y aplicación al análisis de la sustentabilidad urbana. Se presentan algunas nociones generales sobre el concepto de sustentabilidad urbana y la necesidad de encontrar indicadores adecuados para evaluarla. Luego se describen los dos indicadores que mejor abarcan todos los aspectos de la sustentabilidad urbana y que resultan más fáciles de adaptar a la situación particular de las ciudades intermedias de países en desarrollo. A partir de descripciones de las variables relevantes de la problemática ambiental, en cada uno de los índices, se plantean posibles líneas de análisis para adaptarlos a la evaluación de sustentabilidad en el ámbito urbano.
Urbanización y patrones de consumo energético en el continente americano: de lo global a lo local
Authors:   Universidad Politécnica de Yucatán, Cano Regnier , Patiño Rodrigo ,   Centro de Investigación y Estudios Avanzados
Published: December 2020

En este capítulo se formula una metodología que muestra la asociación de la tasa anual de urbanización con el consumo energético per cápita en los países de América, identificando diferentes patrones de demanda energética. Se agregan también algunas aproximaciones de cómo el consumo energético está relacionado con el Índice de Desarrollo Humano y con el consumo de alimentos. En el caso de México, se propone analizar el consumo eléctrico con esta misma aproximación, para comparar diferentes regiones del territorio nacional. La metodología puede ser útil para que los tomadores de decisiones encuentren soluciones nuevas a la reducción neta del consumo energético, basándose en territorios que muestran una mayor eficiencia, en contraste con otros que destacan por su opulencia o pobreza energéticas. En general, se observa que no sólo la disponibilidad de recursos energéticos, sino también las políticas nacionales o internacionales, influyen en los patrones de consumo de energía.

Published: December 2020

Infill walls increase the strength and stiffness of the reinforced concrete frames, but they usually are not considering in design. However, when the infills are considered in the design, the opening for doors/windows necessitates investigation as well. This research work aims to investigate the effect of perforations (openings) in the infill walls on the performance of infilled RC frames, in other words, this research investigates the number of infill walls in infilled RC frames. Based on the current construction practices in Pakistan, two full scales perforated infilled RC frames were constructed in the laboratory. One infilled RC frame has an eccentric door and window (specimen-1) while the other has only window at its centre (specimen-2). Both the specimens were tested against reverse cyclic loading (quasi-static test). From the experimental testing, it was found that infilled RC frame having less amount of opening in infill wall has more resistance to lateral loads, have more stiffness and dissipated higher energy as compared to infilled RC frame having a significant size of the opening in infill wall. Similarly, displacement ductility (µD) and Response modification factor (R) also depend on the quantity of opening in infill wall in infilled RC frame. Doi: 10.28991/cej-2020-03091625 Full Text: PDF

Los multiferroicos magnetodielectricos presentan actualmente una innovadora alternativa en el desarrollo de FE-RAMs. El control de ellas se puede llevar a cabo mediante materiales como la ferrita de bismuto (BiFeO3), sin embargo este presenta algunas dificultades para desarrollar esta tarea como lo es un comportamiento antiferromagnetico y la presencia inevitable de fases secundarias, aunque dichos problemas se pueden solucionar mediante sustitucion cationica que a su vez introducen defectos en la estructura cristalina de la BiFeO3. Los defectos a su vez influyen en la modulacion del efecto magnetodielectrico. El siguieten trabajo presenta la evidencia experimental del control de defectos en la estructura cristalina de BiFeO3 co-dopada con Sr2+ y Mn3+ (Bi0.95Sr0.05Fe1-xMnxO3, Δx=0.1) obtenida mediante metodo mecanico asistido y su influencia en las propiedades magnetodielectricas. Mediante difraccion de rayos X se comprobo la presencia de BiFeO3 en su fase rombohedral. Mediante pruebas magnetodielectricas se comprobo que los defectos infucidos por la sustitucion cationica ayudan en la modulación de las propiedades magnetodielectricas.

En el presente estudio teórico ab initio comparativo se utiliza el código SIESTA®, mediante la Teoría del Funcional de la Densidad (DFT) para comprender las propiedades estructurales y electrónicas de la fase cúbica en el equilibrio de la geometría de dos perovskitas complejas: NaNbO3 y SrTiO3. Se emplean dos pseudopotenciales base: Aproximación de Gradiente Generalizado (GGA) por los autores Perdew-Burke-Ernzerhof, y Aproximación de Densidad Local (LDA) por Ceperley-Alder. Los parámetros de red obtenidos para el NaNbO3 son a0= 3.900 y 4.040 Å con una precisión del 98.86 y 97.6%. Para el SrTiO3 se obtuvieron parámetros de red de a0= 3.969 y 3.811 Å con una precisión de 92.8 y 97.6% respectivamente de cada pseudopotencial. Se demuestra que el comportamiento de ambas estructuras de bandas tiene una transición electrónica indirecta particular con spin no polarizado, con un ancho de banda prohibida de ∼1.28 eV para el NaNbO3 y ∼2.0 eV para el SrTiO3 con el potencial de intercambio-correlación LDA y una estructura de bandas argumentativa de la fiable aplicación de estos materiales en fase cúbica para dispositivos opto-electrónicos.

En el presente trabajo se prepararon polvos de ferrita de níquel (NiFe2O4) mediante el método hidrotermal. Se utilizaron como precursores sales de hierro y de níquel (FeCl3∙6H2O y NiCl2∙6H2O). Se empleó hidróxido de sodio (NaOH) para modificar el pH y como agente precipitante. Los polvos obtenidos se caracterizaron mediante difracción de rayos X (DRX), espectroscopia infrarroja por transformada de Fourier (FT-IR) y técnica de difracción láser. El análisis IR mostraron las bandas características de los enlaces Fe(III)-O-Ni(II), y MO-O. Situadas a 550 y 490 cm-1. Los patrones de difracción de rayos X revelan que los polvos de ferrita de níquel cristalizan en la fase cúbica. La solución de NaOH utilizada como disolvente en la reacción hidrotermal promueve una fase secundaria. Los tamaños de las partículas de ferrita de níquel fueron estimados en 20-40 μm empleando difracción laser. Se realizó un proceso de digestión anaeróbica y realiza su proyección de eficiencia en la obtención de metano.
Sobre a complexidade dos problemas contemporâneos de design
Authors: S. D. Alão Rui
Published: December 2020

Este artigo investiga algumas características dos problemas contemporâneos de design. Argumentamos que a complexidade destes problemas cresceu muito a ponto de colocar em xeque os métodos tradicionais de projeto, tanto em função da instabilidade das paisagens de solução quanto em função da mobilidade dos sistemas nos quais estão imersos. Como principal contribuição, apontamos para a criação de comunidades mistas de designers e usuários e sugerimos que novos processos metodológicos sejam concebidos, prototipados e testados para dar conta de enfrentar problemas de design de alta complexidade.
Design de joias: do que estamos falando?
Authors: Maria Loureiro da Costa Llaberia Engracia
Published: December 2020

Este artigo vem propor uma reflexão a partir de considerações sobre o design de joias e o uso do termo design na joalheria nas diversas acepções com entendimentos distintos no processo de criação e produção joalheira, até sua inserção no campo do Design. Procura-se mostrar como a adoção no português deste termo da língua inglesa, com traduções de conotações amplas, tem permitido uma sobreposição de atividades tão distintas relacionadas à joalheria quanto são as de desenhar criativamente, fazer a joia, até a projetá-la sob a perspectiva de produto de produção industrial, utilizando métodos do Design no projeto de criação e desenvolvimento de artefatos, seja para uma única peça ou para uma coleção para empresas. Trata-se, aqui, de buscar entendimento de modo a criar parâmetros para a prática da profissão de designer de joias no setor joalheiro, tanto no segmento de materiais preciosos como na produção industrial de folheados e bijuterias.
