EFECTOS DEL ALIMENTO VIVO Y MICROENCAPSULADO EN EL CRECIMIENTO Y SOBREVIVENCIA DE POSTLARVAS DE COLOSSOMA MACROPOMUM CUVIER, 1816 (CHARACIFORMES, SERRASALMIDAE)
Authors: Alvarez-Verde Claudio , Llontop-Vélez Carlos , Candela-Diaz José
Published: June 2022

En acuicultura la sobrevivencia de las postlarvas, etapa crítica en los peces, está influenciada por el alimento. La gamitana, Colossoma macropomum Cuvier, 1816, es una especie de gran importancia económica en nuestro país. En el presente trabajo se evaluó el crecimiento de postlarvas de C. macropomum, sometidos a tres tratamientos de alimentación: T , alimento vivo compuesto por nauplios 1 de Artemia; T , alimentación con nauplios de Artemia más alimento experimental microencapsulado y T , 2 3 solamente alimento experimental microencapsulado. El alimento se proporcionó “ad libitum” y se evaluaron el crecimiento de las postlarvas, la tasa de crecimiento específico, la ganancia de peso y la tasa de sobrevivencia. El alimento microencapsulado se preparó mediante la técnica de gelificación, secado y molido. El experimento tuvo una duración de 30 días. Se utilizaron 450 postlarvas de gamitana con tamaño promedio inicial de 0,02 ± 0,012 cm distribuidos en nueve acuarios. El diseño experimental fue completamente al azar con tres tratamientos y tres repeticiones por tratamiento. Los resultados presentaron diferencias significativas entre los tratamientos para la ganancia de peso (g), la tasa de crecimiento específico (%) y supervivencia (%). Para T : 1,25 g; 13,93% y 70,66%; para T : 1,38 g; 14,23 1 2 % y 78%; para T3: 0,83 g; 13,48% y 56,66%, respectivamente. Los parámetros de calidad de agua estuvieron dentro de los rangos adecuados a la especie. Se concluye que los mejores rendimientos se obtuvieron con el tratamiento T , nauplios de Artemia más alimento microencapsulado.

Published: June 2022

En Chile los textos sobre reptiles normalmente expresan que las especies del género Liolaemus son insectívoras, omnívoras y a veces herbívoras. Sin embargo, no se entrega mayor nivel de detalle. Dentro del género Liolaemus se encuentra Liolaemus zapallarensis (Müller & Hellmich, 1933), especie endémica de Chile que habita matorrales costeros con rocas, y se sabe que es omnívora, incluyendo brotes verdes y flores. Con el fin de contribuir al conocimiento de la dieta de esta especie, se planteó como objetivo de esta nota, reportar el registro casual de un componente desconocido en la dieta de la especie. Se reporta la depredación y engullimiento de un individuo de la araña Acanthogonatus sp., por parte de L. zapallarensis en una duna con alto grado de intervención antrópica. La caza se produjo de manera rápida y efectiva.

Published: June 2022

Los microplásticos (MPs) en canales de riego han sido poco estudiadas en Perú. El objetivo de este estudio fue determinar la abundancia y características (tamaño, color y forma) de MPs en sedimentos superficiales de canales de tierra para riego (Yuncaypara y Mejorada) ubicados en el centro poblado de Madeán, distrito de Madeán, provincia de Yauyos, región Lima, Perú. Se muestrearon en cada sitio por triplicado, 1 sitio en canal Mejorada (CM) y 2 sitios en canal Yuncaypara (CY1 y CY2). La separación se realizó con solución salina de alta densidad (ZnCl , cloruro de zinc). Los resultados mostraron la 2 abundancia en CM, CY1 y CY2 que fueron 111,11 ± 19,25; 566,67 ± 88,19 y 66,66 ± 0,00 Ítems/kg de sedimento seco, respectivamente. Las características de tamaño, color y forma, los predominantes fueron pequeños MPs (6-1000 μm), azul y fragmento, respectivamente. No se encontró pellet y espuma. Se concluye que hay presencia y contaminación por MPs en sedimentos superficiales de canales de tierra para riego. Los MPs secundarios fueron los únicos encontrados y a cercanía del sitio de muestreo con el centro poblado presenta mayor abundancia de MPs.
POTENCIAL DE RIESGO ECOTOXICOLÓGICO POR HIDROCARBUROS EN EL ECOSISTEMA COSTERO-MARINO DE VENTANILLA, CALLAO-PERÚ: PARTE - I
Authors: Argota Pérez George , Iannacone Oliver José Alberto
Published: June 2022

El propósito del estudio fue describir el potencial ecotoxicológico por hidrocarburos en el ecosistema costero-marino de Ventanilla, Callao-Perú. Se menciona, que los hidrocarburos de petróleo al adsorberse en los materiales particulados, sedimentos y los tejidos de la fauna acuática ocasionan un desequilibrio ecológico. Asimismo, se producen daños hepáticos y las branquias de los peces, afectación en el crecimiento y la productividad en biomasa. Los efectos pueden ser a agudos (ej.: mortalidad, necrosis, mutagenicidad, asfixia) y crónicos (ej.: procesos de biomagnificación y pérdida de la biodiversidad). Se realizó una predicción de riesgo ecotoxicológico de tipo conservadora mediante el programa computacional Gecotoxic® donde el descriptor de análisis ambiental indicó calificación de tipo alta (81%), mientras que, el descriptor de efecto ambiental igualmente fue de predicción alta, pero al 100 %. Se concluye, que deben evaluarse diversos parámetros para considerar los riesgos a la salud humana como son: concentración equivalente de potencia, valor de barrido de matriz, modelo de riesgo carcinogénico de por vida, máximo consumo diario y factores de equivalencia tóxica. De igual modo, debe entender diversas preguntas en la dinámica de reversibilidad para las zonas afectadas y entre las que se mencionan: 1ro) ¿qué organismos invertebrados pueden considerarse como futuros indicadores de la calidad ambiental costero-marina, 2do) ¿cómo evolucionará la fauna macrobentónica? 3ro) ¿en qué tiempo se restablecerá la interacción trófica?, 4to) ¿cuáles especies amenazadas o en peligro de extinción se afectaron? y 5to) ¿cuánto es la repercusión económica sobre las comunidades pesqueras tradicionales?

Authors:   Faculty of Computer and Mathematical Sciences, Universiti Teknologi MARA, Perak Branch Tapah Campus, Perak, Malaysia, Zulkifli Zalikha
Published: June 2022

Food delivery service is an uprising service that were used worldwide. It can be used in few platforms such as mobile apps or a website. It usually involves 3 types of users which are the customer, the rider, and the restaurant. It also brings a lot of benefit in an individual daily life. If people had no time to prepare their meal, or stuck in a back-to-back meeting session, food delivery service is an option to fix their meal break. However, food delivery service is only available in a busy and high-density household area in Malaysia. This project proposed a UiTM Tapah EAT mobile application for UiTM Tapah Students, a food delivery service that can be used in an Android smartphone as a mobile app and able to receive notification of order status in real-time. Since Tapah is a small town placed in Perak, it also holds a university that occupied with about 2,000 students at one time. These students have few limitations of buying meal outside of the university or they are too busy with their schedule. This project uses Android Studio, an Integrated Development Environment (IDE) for Android app development to design the pages using XML and develop the functions of the mobile app using Java language. Besides, this project also used Firebase, a mobile and web application developments platform that helps in storing the data in real-time. Once the development process complete, this project was tested with functionality test that list all the functions available in the app to be evaluated accordingly. The results of the experiment show that all functions in the app successfully executed including the notification system between two end-users, the customer and the runner.
Deuda externa y reconocimiento. Triangulación de intereses en el conflicto México-Texas, 1837-1844
Authors: Martínez Carmona Gabriel
Published: June 2022

El artículo se divide en tres partes, que se desarrollan de manera cronológica y atiende a tres momentos del vínculo entre deuda externa y reconocimiento. En el primer momento, se analiza la propuesta para triangular el proyecto de conversión formulado por F. de Lizardi y Cía., con la coyuntura de la separación texana ocurrida entre 1837 y 1839. El segundo momento, por su parte, analiza la formulación del proyecto y la experiencia de los enviados texanos a México y Londres en búsqueda del reconocimiento, entre 1839 y 1840. En el tercer momento se analiza cómo la idea del pago de una indemnización cobró vida propia, en el sentido de que se desvinculó de la conversión y tanto el gobierno texano como el británico se apropiaron de la misma, para lograr incentivar al gobierno mexicano a otorgar el reconocimiento, entre 1841 y 1844, en que la coyuntura cambió y el anexionismo a Estados Unidos cobró mayor impulso. Finalmente, en las conclusiones se reflexiona acerca de la relación entre la deuda externa, la indemnización y el reconocimiento.
Generales mulatos y habaneras trasatlánticas. La independencia de Cuba desde una editorial mexicana, 1895-1898
Authors: Díaz Frene Jaddiel
Published: June 2022

En este artículo se intenta reconstruir una historia popular del nacionalismo cubano en México teniendo como eje central los impresos de la editorial capitalina Vanegas Arroyo. Un corrido sobre el general santiaguero Antonio Maceo, solicitado desde Veracruz y una habanera metamorfoseada entre fronteras trasatlánticas, ambas obras ilustradas por José Guadalupe Posada, permitirán acceder a los combates cotidianos sobre las visiones de los ejércitos contendientes, sus integrantes y la legitimidad de sus causas. Estos relatos políticos abren una ventana privilegiada para observar el funcionamiento de la editorial, la circulación de los impresos y los diálogos de los corridos y los grabados con la prensa periódica nacional e internacional.

La red de innovación de José Erdos Blau en el sector farmacéutico mexicano (1940-1970)
Authors: Godínez Reséndiz Rogelio , Aceves Pastrana Patricia , Schifter Aceves Liliana
Published: June 2022

Después de la segunda guerra mundial, tuvo lugar un crecimiento importante de la investigación farmacéutica desarrollada en México, gracias al establecimiento en el país de instituciones públicas y compañías privadas interesadas en realizar esta actividad. Sin embargo, a pesar de los importantes avances alcanzados en la posguerra por científicos nacionales y extranjeros, la producción de innovaciones y de patentes mexicanas se dio de manera irregular, ante la falta de una infraestructura científica en el sector farmacéutico. No obstante, entre los líderes en la producción de patentes locales se encontraba el científico húngaro-mexicano José Erdos Blau de la Escuela Nacional de Ciencias Biológicas (ENCB), perteneciente al Instituto Politécnico Nacional (IPN). El objetivo de este artículo es analizar la red de innovación que Erdos creó alrededor de la ENCB con la colaboración de diversas empresas. Se muestra que esta red se convirtió en una de las más importantes del sector farmacéutico mexicano, impulsando considerablemente la investigación en el campo de la química orgánica y el desarrollo de medicamentos. La información presentada se obtuvo a partir del examen de las patentes farmacéuticas registradas durante el periodo de estudio, de documentos provenientes de archivos y de revistas científicas y de divulgación publicadas por los químicos y farmacéuticos de la época.

An Overview of Heat Transfer Enhancement Based Upon Nanoparticles Influenced By Induced Magnetic Field with Slip Condition Via Finite Element Strategy
Authors: Hafeez Muhammad B. , Krawczuk Marek , Shahzad Hasan
Published: June 2022

The mathematical model of heat generation and dissipation during thermal energy transmission employing nanoparticles in a Newtonian medium is investigated. Dimensionless boundary layer equations with correlations for titanium dioxide, copper oxide, and aluminium oxide are solved by the finite element method. Parameters are varied to analyze their impact on the flow fields. Various numerical experiments are performed consecutively to explore the phenomenon of thermal performance of the combination fluid. A remarkable enhancement in thermal performance is noticed when solid structures are dispersed in the working fluid. The Biot number determines the convective nature of the boundary. When the Biot number is increased, the fluid temperature decreases significantly. Among copper oxide, aluminium oxide, and titanium oxide nanoparticles, copper oxide nanoparticles are found to be the most effective thermal enhancers.

Published: June 2022

The aim of this study was to evaluate the effects of carrot pomaces dried at two temperatures as a feed component on growth performance, environmental sustainability, and meat quality in common carp (Cyprinus carpio). Three diets were developed: a control without pomace (CON); CPL with 15.5% carrot pomace dried at 40°C and CPH with 23.6% carrot pomace dried at 120°C. A total of 240 two-year-old common carp (average body weight of individual: 1025 g) were randomly distributed into 12 tanks, four per treatment, including 20 fish per tank. The experiment was performed using an outdoor open flow aquaculture system. The growth trial lasted 60 days, after which fish samples were taken for analysis of meat quality parameters. There were no significant differences between groups in terms of the final body weight, protein efficiency ratio, or survival rate. However, in terms of weight gain, specific growth rate, and feed conversion ratio, fish fed the CPH diet exhibited significant worsening. Moreover, the fillets of fish from the CPH group exhibited a darker coloration compared to the CON diet. It is concluded that high temperature drying of carrot pomace added to carp diet negatively affected fish quality. It should be also emphasized that inclusion of the both carrot pomaces tested in this study significantly increased the usage of fish meal per kilogram of fish body weight gain. These results showed a reduced efficacy of using carrot pomace in practical and sustainable common carp nutrition.
Jealousy and revenge as accompanying elements of the motivation of a murder committed in a state of passion
Authors: Sergeeva Anzhelika Anatol'evna
Published: June 2022

The subject of the study is the norms of the current criminal legislation establishing responsibility for the commission of murders, the specifics of the motivation of criminal encroachment by feelings of jealousy and revenge, the principles of distinguishing the subjective side of murders committed as a result of a quarrel or in the presence of personal hostility, and murders committed in a state of passion. On the basis of a combination of general scientific and private scientific methods, the author revealed the ratio of jealousy and revenge in the structure of motivation for murders, revealed the peculiarities of the emergence of affected intent. At the same time, the results of studying the materials of criminal cases were used, on the basis of which the conflicting rules of qualification of attacks on life were revealed. The scientific novelty of the conducted research consists in refuting the established stereotype regarding the exclusively provocative role of the victim in the formation of intent to murder, qualified under Article 107 of the Criminal Code of the Russian Federation. The author proves that not only the behavior of the victim, but also the emotional sphere, reflected in the consciousness of the guilty and characterized by the parameters of jealousy or revenge, forms an affected intent. The author's conclusions have scientific novelty in terms of distinguishing situations in which the motive of jealousy and the motive of revenge acquire a dominant meaning in the structure of intent, but it can be both spontaneous and premeditated.
Brazilian military service and preparation for the Second World War
Authors: Ferraz Francisco César Alves
Published: June 2022

The aim of this work is to analyze the development of the Military Service in Brazil during the 1930s and 1940s and the consequences of this recruitment structure for the creation of an expeditionary army division to fight in the Second World War. The Brazilian Army aimed to democratize the call for military service and promote the selection of the best physical and instructional outcomes for the country in the case of an eventual war. However, with the dodging of the middle and upper classes to be recruited, both during the peace and the Second World War, the recruitment focused predominantly on the most impoverished and lowest educated groups of the society. Nevertheless, it provided a group of soldiers to be better prepared than that which originated from the Military Service. This paper concludes that the war experience, however, did not impact the improvement of the Brazilian military service in times of peace.
Back to basics: assessing military involvement in politics in contemporary Brazil
Authors: Vitelli Marina
Published: June 2022

As Brazil showed signs of progress in civil-military relations in the late nineties and early 2000s, research moved from civilian control to defense policy topics, resulting in neglect of less obvious forms of military involvement in politics, which pre-date Bolsonaro. To support our claim, we begin by critically reviewing existing frameworks for assessing progress in civilian control and propose returning to the field’s primary concern with military intervention in politics by using three indicators - military presence in government; public commentary by military officers; and episodes of military contestation – and their implications regarding the armed forces, politicians, and society. Then, we make an account of instances of the three indicators during Dilma Rousseff’s and Michel Temer’s presidencies. We conclude that military involvement in politics in Brazil is a pervasive social phenomenon posing serious risks for democracy.

This research will try to analyze this work in interphases with the proposals of the eugenicists on the issue of immigration.
“Brazil has its eye on you”: sexual panic and the threat of sex tourism in Rio de Janeiro during the FIFA World Cup, 2014
Authors: Blanchette Thaddeus , Da Silva Ana Paula
Published: June 2022

The present article draws upon ethnographic research undertaken in the principal sexual commercial zones of the city of Rio de Janeiro and in the institutions and agencies responsible for combating sexual exploitation in Rio during the 2012-2014 period, as well as the analysis of media stories, to explain how and why carioca authorities have not been able to discover and repress the sex crimes they claim exist on a massive scale. We seek to show what effects the moral panic over child sexual exploitation during the 2015 World Cup has had in transforming security in Rio de Janeiro.
Parque Madureira: Exceptional or Merely Good in Comparison?
Authors: McCann Bryan
Published: June 2022

Nearly all the major urban planning initiatives associated with the ongoing transformation of Rio de Janeiro, such as the renovation of the port district, the creation of the Olympic village, and the opening of cross-municipal bus-rapid-transit lines, have been greeted by protests and criticism from architects and urban planners. One project, the Parque Madureira, a new green corridor in the city’s North Zone, has received great acclaim by Brazilian and international urbanists. Local residents seem to like it, too. Representatives of social movements, in contrast, point out that the Parque Madureira involved the same kind of favela removal criticized elsewhere. Is the Parque Madureira truly exceptional or does it merely look good in comparison to shortcomings elsewhere? What are its implications in the larger transformation of the city? This paper seeks to answer those questions by comparing the Parque Madureira both to other current urban interventions and to older parks, such as the Quinta da Boa Vista and the Aterro do Flamengo.
Quando o projeto era moda: projetos sociais, juventudes e a política de “pacificação” no Rio de Janeiro.
Authors: Cecchetto Fátima , Corrêa Juliana , Farias Patrícia
Published: June 2022

A questão central deste artigo é explorar as implicações de projetos sociais dirigidos aos jovens moradores de favelas no Rio de Janeiro, dentro de um contexto de investimentos estatais com a implantação das Unidades de Polícia Pacificadora - as UPPs. Busca-se examinar as representações dos jovens sobre o papel dos “projetos” em suas trajetórias e os discursos sobre a atuação policial nos territórios “pacificados”. A partir de trabalho de campo, observação participante, grupos focais e entrevistas,  analisamos os desafios dos programas destinados aos jovens em situação de vulnerabilidade, cuja precariedade compromete o desenvolvimento do protagonismo juvenil. Problematizamos também os avanços e dilemas do policiamento de proximidade nas localidades afetadas pela política de “guerra às drogas”. Concluímos que enquanto as políticas voltadas para a juventude, incluindo as de segurança pública forem apenas moda, não será possível a mudança que assegure a mobilidade, ampliando o horizonte de expectativas de inclusão social.

Ações de liberdade de índias e índios escravizados no Estado do Maranhão e Grão-Pará, primeira metade do século XVIII
Authors: Bombardi Fernanda Aires , Prado Luma Ribeiro
Published: June 2022

Nas atas do Tribunal da Junta das Missões das capitanias do Pará e Maranhão existe um considerável número de denúncias que demonstram as irregularidades do sistema de escravidão indígena na primeira metade do século XVIII, momento em que ocorre um incremento das atividades legais e ilegais de captura e exploração de mão de obra nativa. Essas denúncias estavam associadas às ações de liberdade em que indígenas solicitavam ao Tribunal o fim de seu cativeiro e de seus familiares. Assim, o objetivo deste trabalho é avaliar de que maneira índias e índios escravizados acionaram as estruturas jurídicas coloniais para sair do jugo de seus senhores. Argumentamos que, ao realizar as ações, os indígenas objetivavam livrar-se de situações de maus tratos e jornadas árduas de trabalho, bem como conquistar o direito de escolher a quem servir, com quem casar, onde morar e, fundamentalmente, no caso das índias, de transmitir a sua condição de liberdade à descendência.

The purpose of this article is to go through the chronological process of the speech of crystallization the thought about indigenous cultures and ethnic homogenization, inviting reflection on the symbolic power that emanates from the speech, on the assumption that the speech acts as a construction tool of the hegemonic order, preventing the presence of indigenous ethnic and cultural diversity.
(R)existir com imagens: considerações sobre a produção audiovisual indígena no Brasil
Authors: Nunes Karliane Macedo
Published: June 2022

O presente artigo trata das produções audiovisuais indígenas realizadas no Brasil, sobretudo aquelas vinculadas ao projeto Vídeo nas Aldeias, que desde o final dos anos 1980 vem promovendo oficinas de formação audiovisual em diversos territórios, incentivando o protagonismo de jovens indígenas na construção de suas imagens e narrativas. Chama a atenção a forma criativa como os jovens cineastas vem se apropriando das tecnologias de modo a produzir filmes que - para além propósito inicial de registrar e “preservar” a tradição – potencializam as possibilidades abertas pelo cinema, pondo-se a criar novas imagens, (re)inventar culturas, abalar imaginários, manter-se em movimento, (r)existir.

As águas de São Paulo: um déficit cultural paulistano
Authors: Escorel Daniel
Published: June 2022

Em um momento em que a cidade de São Paulo se torna protagonista da crise hídrica que coloca o Brasil em alerta, a necessidade da mudança do paradigma cultural-ambiental na maior metrópole brasileira é mais do que nunca crucial para a sociedade paulista. A “locomotiva"do país é entretanto detentora de fartos recursos hídricos e assenta sua construção sobre uma das mais ricas bacias hidrográficas do continente Sul-Americano. O desperdício e mal uso deste recurso que definirá a história da Humanidade no Século XX alia-se à desinformação e desconhecimento da população do território da riqueza que ali reside. Para além de questões técnicas de engenharia, raízes mais profundas da história da formação da paisagem da cidade revelam a perda de atributos culturais por parte do paulistano. Uma câmbio cultural será imprescindível para a resolução de crise da sabida proporção.
Life, Death, and Fear in the Twenty-First Century Brazilian Graphic Novel
Authors: Holcombe William Daniel
Published: June 2022

This essay identifies influential and prominent twenty-first century Brazilian graphic novels and associated sociocultural affects, such as racial inequality, gender disparities, and social dysfunctionality, as this Post-Boom literary genre expands into a global market. A specific selection of influential texts, key citations, provocative images, and disturbing themes is analyzed, revealing humanistic leitmotifs such as fear of death, violence, and disease, as well as fear of life, immigrant acculturation, futurism, and authoritarianism. The selection is limited to Brazilian graphic novels produced so far in the twenty-first century that have achieved a significant international readership: Daytripper (2014) by Fábio Moon and Gabriel Bá; Two Brothers (2015) by Moon, Bá and Milton Hatoum; Pixu (2009) by Moon, Bá, Becky Cloonan, and Vasilis Lolos; V.I.S.H.N.U (2012) by Eric Archer, Ronaldo Bressane, and Fabio Cobiaco; and Notas de um tempo silenciado (2015) by Robson Vilalba.

Computing Boundaries for Reasoning in Sub-Ontologies
Authors:   Institut für Theoretische Informatik TU Dresden, Baader Franz , Knechtel Martin ,   SAP AG Dresden, Peñaloza Rafael ,   Institut für Theoretische Informatik TU Dresden
Published: June 2022

Consider an ontology T where every axiom is labeled with an element of a lattice (L, ≤). Then every element l of L determines a sub-ontology Tl, which consists of the axioms of T whose labels are greater or equal to l. These labels may be interpreted as required access rights, in which case Tl is the sub-ontology that a user with access right l is allowed to see, or as trust levels, in which case Tl consists of those axioms that we trust with level at least l. Given a consequence α (such as a subsumption relationship between concepts) that follows from the whole ontology T, we want to know from which of the sub-ontologies Tl determined by lattice elements l the consequence α still follows. However, instead of reasoning with Tl in the deployment phase of the ontology, we want to pre-compute this information during the development phase. More precisely, we want to compute what we call a boundary for α, i.e., an element μα of L such that α follows from T l iff l ≤ μα. In this paper we show that, under certain restrictions on the elements l used to define the sub-ontologies, such a boundary always exists, and we describe black-box approaches for computing it that are generalizations of approaches for axiom pinpointing in description logics. We also present first experimental results that compare the efficiency of these approaches on real-world ontologies.
Completion-based computation of least common subsumers with limited role-depth for EL and Prob-EL⁰¹
Authors:   Institut für Theoretische Informatik TU Dresden, Peñaloza Rafael , Turhan Anni-Yasmin ,   Institut für Theoretische Informatik TU Dresden
Published: June 2022

The least common subsumer (lcs) w.r.t general EL-TBoxes does not need to exists in general due to cyclic axioms. In this report we present an algorithm for computing role-depth bounded EL-lcs based on the completion algorithm for EL. We extend this computation algorithm to a recently introduced probabilistic variant of EL: Prob-EL⁰¹.
SAT Encoding of Unification in EL
Authors:   Institut für Theoretische Informatik TU Dresden, Baader Franz , Morawska Barbara ,   Technische Universität Dresden
Published: June 2022

The Description Logic EL is an inexpressive knowledge representation language, which nevertheless has recently drawn considerable attention in the knowledge representation and the ontology community since, on the one hand, important inference problems such as the subsumption problem are polynomial. On the other hand, EL is used to define large biomedical ontologies. Unification in Description Logics has been proposed as a novel inference service that can, for example, be used to detect redundancies in ontologies. In a recent paper, we have shown that unification in EL is NP-complete, and thus of a complexity that is considerably lower than in other Description Logics of comparably restricted expressive power. In this paper, we introduce a new NP-algorithm for solving unification problem in EL, which is based on a reduction to satisfiability in propositional logic (SAT). The advantage of this new algorithm is, on the one hand, that it allows us to employ highly optimized state of the art SAT solverswhen implementing an EL-unification algorithm. On the other hand, this reduction provides us with a proof of the fact that EL-unification is in NP that is much simpler than the one given in our previous paper on EL-unification.
Bridging the Catalyst Reactivity Gap Between Au and Cu for the Reverse Water Gas Shift Reaction
Authors: Yan Dengxin , Kristoffersen Henrik H. , Castelli Ivano E. , Rossmeisl Jan
Published: June 2022

The reverse water gas shift reaction (rWGSR) is highly relevant for CO2 utilization in sustainable fuel and chemical production. Both Au and Cu are interesting for rWGSR catalysis, but it turns out that the reactivities of Au and Cu are very different. In this study, we consider alloys made from Au, Ag, Cu, Pt, and Pd to identify surfaces with reactivities for CO2 dissociation in between Cu(111) and Au(111). Additionally, interesting alloy surfaces should have activation energies for CO2 dissociation that are only a little higher than the endothermic reaction energy. We find that certain Cu based alloys with Ag and Au meet these criteria, whereas alloys containing Pt or Pd do not. The low additional cost in activation energy occurs when the transition state and final state configurations are made to look very similar due to the placement of the different metal elements in the surface. Finally, we construct a kinetic model that compares the rate of the rWGSR to the estimated rate of unwanted side reactions (i.e. methane formation or coking) on Ag-Cu alloy surfaces with varying composition and random placement of the Ag and Cu atoms. The thermodynamics favor methane formation over rWGSR, but the model suggests that Ag-Cu alloy surfaces are highly selective for the rWGSR.
QUESTION ANSWERING SYSTEM FOR HOSPITALITY DOMAIN USING TRANSFORMER-BASED LANGUAGE MODELS

Published: June 2022

Recent research demonstrates significant success on a wide range of Natural Language Processing (NLP) tasks by utilizing Transformer architectures. Question answering (QA) is an important aspect of the NLP task. The systems enable users to ask a question in natural language and receive an answer accordingly. Most questions in the hospitality industry are content-based, with the expected response being accurate data rather than”yes” or ”no.” Therefore, it requires the system to understand the semantics of the questions and return relevant answers. Despite several advancements in transformer-based models for QA, we are interested in evaluating how it performs with unlabeled data using a pre-trained model, which could also define-tune. This project aims to develop a Question-Answering system for the hospitality domain, in which text will have hospitality content, and the user will be able to ask a question about them. We use an Attention mechanism to train a span-based model that predicts the position of the start and end tokens in a paragraph. By using the model, the users can directly type in their questions in the interactive user interface and receive the response. The data set for this study is created using response templates from the existing dialogue system. We use the Stanford Question and Answer (SQuAD 2.0) data structure to form the dataset, which is mostly used for QA models. During phase1, we evaluate the pre-trained QA models BERT, ROBERTa, and DistilBERT to predict answers and measure the results using Exact Match(EM) and ROUGE-LF1-Score. In Phase 2 of the project, we fine-tune the QA models and their hyper-parameters by training the model with hospitality data sets, and the results are compared. The fine-tuned ROBERTa models achieved the maximum of ROUGE-L F1-Score and EM of 71.39 and 52.17, respectively, which is a relatively 4% increase in F1-Score and 8.7% increase in EM score compared to the pre-trained model. The results of this project will be used to improve the efficiency of the dialogue system in the hospitality industry.
“malestar” que no tiene nombre

En el actual contexto pandémico emerge un escenario de desigualdad entre mujeres y hombres muy preocupante derivado de las desigualdades que se han agravado durante esta pandemia global.  Este artículo examina cómo la pandemia de la COVID19 ha impactado en la brecha de género existente en la ciencia y en las consecuencias que esto ha originado en la salud y calidad de vida de las mujeres académicas. A través del análisis de varios estudios realizados en nuestro país y de la literatura científica internacional, se concluye que el confinamiento ha actuado como acelerador de la desigualdad entre académicos y académicas, derivado principalmente la “brecha de cuidados” y de la división sexista del trabajo que aún pervive en la academia, provocando un deterioro y precarización de las condiciones de trabajo de las investigadoras :más agotamiento, menos horas de sueño, más cansancio, más horas de teletrabajo académico, trabajo reproductivo y de cuidados y con menos tiempo disponible para sí mismas, y en consecuencia, menos producción científica frente a sus compañeros varones, con las futuras consecuencias en la brecha salarial que ello va a significar.
OPTICAL PARALLEL HALF ADDER USING SEMICONDUCTOR OPTICAL AMPLIFIER-ASSISTED SAGNAC GATES
Authors: Kumar Gayen Dilip
Published: June 2022

Today communication needs huge operational speed. This will be accomplished in case the conventional carrier of data, i.e. electron is supplanted by a photon for gadgets based on switching and logic. Gates are the basic building pieces of advanced frameworks. Different logic and arithmetic operations can be done using this gate. Optical logic and arithmetic operations are exceptionally much anticipated in high-speed communication frameworks. In this paper, we have presented parallel models to perform the addition of two binary digits based on terahertz optical asymmetric demultiplexer (TOAD)/semiconductor optical amplifier (SOA)-assisted Sagnac gates. Using only two TOAD-based switches we have designed a parallel half adder. This optical circuit increases the speed of calculation and is also capable of synthesizing light as an input to form the output. The most advantage of this parallel circuit is that no synchronization is required for distinctive inputs. The circuit is hypothetically planned and confirmed by numerical simulations.

The creation and dissemination of COVID-19 stigma can damage efforts exhibited to prevent and counter the spread of the virus. A basic factor that triggers COVID 19 stigma is infodemic. It seems also that stigma and infodemic in the time of COVID-19 pandemic are interrelated to each other and work together. The new front in the COVID-19 battle should be therefore fighting stigma and infodemic driving it given that their impact can be very detrimental and long-lasting without suitable social measures needed to empower and support the vulnerable populations during such a global pandemic. Based on some selected literature and research conducted during the outbreak period of the coronavirus pandemic, the current article sheds light on this topic by focusing on the following points: 1). Definition of Stigma and relevant terms; 2). Victims of social stigma during the COVID 19 Pandemic; 3). Consequences of COVID 19-related Stigma; 4). Infodemic as a key driver of COVID 19-related Stigma; 5). Guidelines to fight stigma and infodemic during COVID-19 pandemic.
