Misinformation Regarding 5G and COVID-19 and the Psychological Mechanism Behind Them
Authors: Chen Yufan
Published: October 2020

In late 2019, the COVID-19 pandemic started to spread around the world (Fauci, Lane, & Redfield, 2020). Along with the virus, misinformation about the pandemic started to spread as well. Rumors regarding the usefulness of masks, conspiracy theories regarding the legitimacy and origin of the virus, and the astonishing amount of fake news about the virus posted online every day are extremely hard to distinguish from factual news reports (Mian & Khan, 2020; Brennan, Simon, Howard, & Nielson, 2020). One example of this alarming phenomenon is the conspiracy theory that links the pandemic to 5G, which is in the early stages of being commercialized (Shafi et al., 2017). This conspiracy theory claims that 5G and the radiation it causes disrupted the natural magnetic field of the earth, and started this pandemic (Geary, 2020). Though it might look like an absurd concept, the “5G causes Corona” conspiracy theory has gained an extremely large following, and the effect of that is clear on and off the internet, as multiple 5G antennas have been vandalized all over the world by mobs claiming they are the means of spreading the coronavirus (Reichert, 2020). The fabrication and spreading of misinformation regarding 5G and its link to the coronavirus are largely connected with the multiple psychological mechanisms and manipulation of sources.
Cost-minimization analysis of negative pressure wound therapy technologies for the treatment of moderate-to-severe foot infections
Authors: Mallow Peter J , Tepsick Jon , Davis Kathryn E , Lavery Lawrence A
Published: October 2020

Aim:
The objective was to estimate the cost of care associated with two negative pressure wound therapy (NPWT) technologies used to treat patients admitted to the hospital with moderate-to-severe foot infections.
Materials & methods:
A decision tree simulation model was developed to estimate the hospital costs associated with two different NPWT technologies: Cardinal Health™ PRO (NPWT-C) and V.A.C. ULTA™ (NPWT-K). Clinical data were obtained from a previously completed single-site prospective trial. One-way and probabilistic sensitivity analyses were performed to gauge the robustness of the results.
Results:
The total expected per-patient costs were US$41,206 (SD: US$8,194) for NPWT-C and US$44,439 (SD: US$8,963) for NPWT-K.
Conclusion:
This study found that NPWT-C was expected to minimize the total costs over the episode of treatment. Larger and more clinically diverse studies are recommended to confirm these findings.

Capitalismo fósil en el siglo XXI: mecanismos económicos, energéticos, militares y elitistas para desencadenar el colapso planetario
Authors: Cano Ramírez Omar Ernesto
Published: October 2020

Esta investigación aborda los mecanismos estructurales que mantienen la quema de combustibles fósiles y las emisiones de gases de efecto invernadero a nivel planetario, a pesar de que ya se conocen y se sufren sus efectos devastadores sobre el clima, la biosfera y la humanidad, y a pesar de las numerosas conferencias y negociaciones internacionales. Se parte de los estudios sobre capitalismo fósil elaborados por Elmar Altvater, Ian Angus y Andreas Malm para precisar el carácter capitalista y de clase de la crisis ambiental actual, mostrando que el origen del problema no es la “sobrepoblación” sino las actividades que imponen, y de las cuales se benefician las élites fósiles. Para ello se usan mediciones sobre aspectos económicos, energéticos, militares y de clase que mantienen (y mantendrán) la quema de combustibles fósiles durante el siglo XXI. Se proponen dos categorías para sintetizar el motor capitalista de esta “destrucción acumulada” y la responsabilidad objetiva de quienes han provocado y se han beneficiado de esta amenaza: 1) el complejo militar-industrial-fósil, y 2) las élites fósiles, ambas siguiendo la obra de C. Wright Mills. Finalmente, se muestra que de no frenar el despilfarro de energía en beneficio de las élites fósiles se estará desencadenando un colapso a nivel planetario que podría ser irreversible.

Es importante señalar su relación con los periodistas, quienes se transforman en antagonistas al cuestionar las declaraciones de los mandatarios.
El “espacio alimentario” construido por los actores: central de abasto de la Ciudad de México
Authors: Del Río Rodríguez Claudia G. , Trujillo Ortega Laura
Published: October 2020

El concepto de espacio alimentario reflexiona sobre lo alimentario y su delimitación espacial. Aplicamos ambos conceptos, alimentario y espacio, como categorías de análisis para explicar el mercado más grande del mundo de provisión de alimentos: la Central de Abasto de la Ciudad de México (CEDA-CDMX). Al vincular dichos conceptos en este análisis, permitió un rompimiento epistemológico de la explicación funcionalista y sistémica de la alimentación, lo que dio paso a la reflexión con base a las aproximaciones teóricas afines con el enfoque de la economía política y relacional. Se asume que lo agroalimentario es resultado de la interacción de múltiples relaciones que van desde la agricultura hasta la construcción de cuerpos e identidades alimentarias que se desarrollan en heterogéneos y dinámicos espacios-tiempo. Se concibe como espacio a las relaciones que se establecen de manera voluntaria e inadvertidamente dentro de él; que construyen y configuran el espacio mismo a partir de la coexistencia de las diferentes redes de actores que se involucran. Este artículo reflexiona en torno a ambas categorías y brinda una explicación de por qué la CEDA-CDMX es el espacio alimentario que ha regido el proceso de aprovisionamiento de alimentos de México desde su creación.

Authors: Freitas Carolina Alvim de Oliveira
Published: October 2020

O artigo busca resgatar o processo de transformações socioespaciais na área que corresponde à Subprefeitura de Itaquera, na cidade de São Paulo, comparando sua centralidade (distrito de Itaquera) com o Conjunto Habitacional José Bonifácio (distrito de José Bonifácio). Para tanto, analisam-se dois ciclos da construção imobiliária: o período de 1970 a 1985, quando foi realizado o projeto dos conjuntos habitacionais do Banco Nacional de Desenvolvimento na região, por meio da Cohab-SP; e o de 2000 a 2015, intervalo em que foram implementadas infraestruturas, serviços e também investimentos imobiliários em razão da construção da Arena Corinthians no contexto da Copa do Mundo de Futebol. O intuito é demonstrar como o modelo centro-periferia, tradicional na interpretação sobre as cidades latino-americanas, não se aplica ao movimento de continuidades e descontinuidades da região em estudo.

Authors: Aleksandrova Alina A. , Zhuzhin Maksim S. , Dulepova Yuliya M.
Published: October 2020

Energy saving today is an integral part of the development strategy of agricultural organizations. Considerable attention is paid to the modernization and automation of technological processes in agricultural enterprises, which can improve the quality of work and reduce the cost of production. The direction of modernization is to reduce the consumption of electric energy by improving the water treatment system in livestock complexes. (Research purpose) The research purpose is to determine the potential of solar energy used in the Nizhny Novgorod region and to determine the possibility of its use for water heating in livestock complexes and to consider the cost-effectiveness of using a device to heat water through solar energy. (Materials and methods) Authors used an improved algorithm of Pixer and Laszlo, applied in the NASA project «Surface meteorology and Energy», which allows to calculate the optimal angle of inclination of the device for heating water. (Results and discussion) Designed a mock-up of a livestock complex with a solar water heater installed on the roof, protected by patent for invention No. 2672656. A mathematical model was designed experimentally to predict the results of the plant operation in non-described modes. (Conclusions) The article reveales the optimal capacity of the circulation pump. Authors have created a mathematical model of the device that allows to predict the water heating in a certain period of time.

Power Model of a Small Wind Plant
Authors: Morenko Konstantin S. , Morenko Sergey A.
Published: October 2020

The production of small wind turbines requires constant modification of their designes. One of the main criteria for efficiency is the power of the wind farm. It makes it possible to evaluate the economic effect in simple categories and by simple means. (Research purpose) The research purpose is to develop a simplified scheme for estimating power flows in a wind farm to assess its main technical and economic indicators. (Materials and methods) The article describes the main operating modes of small wind power plant and correlates them with wind speeds. A small wind turbine with a capacity of 1.8 kilowatt with attack angle control with a nominal wind speed of 8 meters per second was used as the initial sample for testing. The dependence of the power of an operating small wind farm on the wind speed are presented in the article and was used for creating a mathematical model. (Results and discussion) It has been suggested that the efficiency at the nominal wind speed is maximum, but at the starting wind speed it is close to zero. The article presents a power model, the total power output of the installation, the static power loss dynamic power loss of power and aerodynamic limitations. In this case, the power of dynamic losses depends on the overall efficiency of the wind turbine, which is a function of the wind speed. The article presents graphical representation of these power flows. (Conclusions) The theoretical dependence of wind turbine capacity flows is a simple way to determine them in an existing wind turbine. The main characteristics of the model can be calculated from the dependence of power on wind speed, which significantly expands the possibilities of its application for further research. The model can be used in evaluating the effectiveness of the designed structure or changes in it.

Authors: Sergeev Nikolay S. , Zapevalov Mikhail V. , Gritsenko Alexander V.
Published: October 2020

In the continental climate of the southern Urals, rapeseed compares favorably with many forage and traditional silage crops with a high protein content and adaptive properties. The cultivation of rapeseed guarantees the production of its own seeds, up to 40 percent of oil, 60 percent of cake and 98 percent of rapeseed flour. (The research purpose) The research purpose is in improving the efficiency of rapeseed cultivation and rational use of rapeseed seeds, rapeseed flour and oil in the agricultural production in the Chelyabinsk region. (Materials and methods) The influence of various forecrops on the productivity and quality of spring rape seeds in the links of grain-pair crop rotations in the Northern forest-steppe of the Chelyabinsk region were studied. Authors have analyzed the chemical composition of the soil and seeds of spring rape after various forecrops. (Results and discussion) The article proposes to reduce energy costs during pressing and reduce residual oil in the cake after pre-grinding of rapeseed by cutting method using a centrifugal-rotary shredder. The article shows that rapeseed flour has a good flowability and is easily mixed with other feeds. It was found that partial replacement of concentrates with rapeseed flour in the amount of 8-12 percent of the total weight in the diet of lactating cows contributes to an increase in milk productivity by 1.1-1.8 kilograms in terms of milk of 4 percent fat content. (Conclusions) It has been revealed that in order to increase the yield and quality of spring rape seeds, it is necessary to place them on the best forecrops. It was found that when 75 percent of rapeseed oil is mixed with 25 percent of diesel fuel, the obtained biodiesel is not inferior to diesel in terms of energy indicators. The article proves that when cultivating rapeseed for seeds on an area of 100 hectares, it is possible to produce 94.5 tons of biodiesel fuel, 106.0 tons of cake with an oil content of 5 percent and 8.4 tons of oil sludge, the estimated economic effect after sale is of 3,813,325 rubles.
Transfer learning in hybrid classical-quantum neural networks
Authors: Mari Andrea , Bromley Thomas R. , Izaac Josh , Schuld Maria , Killoran Nathan
Published: October 2020

We extend the concept of transfer learning, widely applied in modern machine learning algorithms, to the emerging context of hybrid neural networks composed of classical and quantum elements. We propose different implementations of hybrid transfer learning, but we focus mainly on the paradigm in which a pre-trained classical network is modified and augmented by a final variational quantum circuit. This approach is particularly attractive in the current era of intermediate-scale quantum technology since it allows to optimally pre-process high dimensional data (e.g., images) with any state-of-the-art classical network and to embed a select set of highly informative features into a quantum processor. We present several proof-of-concept examples of the convenient application of quantum transfer learning for image recognition and quantum state classification. We use the cross-platform software library PennyLane to experimentally test a high-resolution image classifier with two different quantum computers, respectively provided by IBM and Rigetti.

Published: October 2020

Interiority is not just the science of interior design that meets the needs of function and aesthetics alone. Both of these are indeed the main 'task' in interior design. Each building is design and built to fulfill certain functions. Hotels, apartments, and houses for example, serves as a means of accommodation. Restaurant serves as a commercial building that meets the needs of food. A public building should be accessible and used by a variety of different needs. These buildings must be accessible to those who can see or not (blinds), walkers and wheelchair users, and those who are able to listen or not (deaf/hard of hearing). This paper is study of application of universal design that is accessible of campus buildings that function as container of Tri Dharma of Higher Education activity. The case studies taken in this research are Universitas Mercu Buana in West Jakarta and University of Daegu in South Korea. The study was conducted by studying the universal design of the two universities by considering two parameters, namely universal design and usability, by conducting literature studies and user interviews. From the results of the study it is found that universities in Daegu have made universal design and usability factors an important part of design, while Universitas Mercu Buana in West Jakarta hasn’t yet fully made these two factors as part of the design, with many facilities not being able to accessed and used universally well.

Published: October 2020

Keandalan suatu gardu induk didukung dengan kondisi dari peralatan-peralatan yang terdapat di gardu induk tersebut. Gardu Induk Bandung Selatan merupakan salah satu gardu induk yang menjadi objek vital nasional sebagai jalur backbone di daerah bandung raya. Gardu induk ini sering dihadapkan dengan anomali terhadap suatu perlatan, salah satunya pada peralatan pemutus tenaga tegangan tinggi yang dihadapkan dengan anomali berupa kenaikan nilai tahanan kontak yang signifikan pada kontaknya. Tentu saja perubahan nilai tahanan kontak yang signifikan ini perlu dievaluasi secara benar sehingga menghasilkan keputusan yang tepat dalam penanganan nilai asset.Untuk mendukung keandalan peralatan tersebut diperlukan sistem manajemen evaluasi terhadap kelayakan suatu peralatan dalam melakukan fungsinya dengan mengidentifikasi potensi penyebab kegagalan fungsi akibat kerusakan pada suatu peralatan dengan menggunakan metode FMEA. Metode ini bertujuan mengetahui penyebab dan kondisi suatu peralatan yang mengalami gangguan dalam hal ini perubahan nilai tahanan kontak yang signifikan yang dapat menyebabkan kegagalan fungsi pada peralatan tersebut. Metode ini untuk mendukung dalam pengambilan keputusan terhadap kondisi pmt akibat perubahan nilai tahanan kontak yang tinggi sehingga didapatkan prioritas penggantian peralatan. Dari hasil evaluasi 13 unit PMT yang terdapat di Gardu Induk Bandung Selatan didapatkan hasil bahwa, terdapat satu unit PMT bay cigereleng 1 yang memiliki nilai tahanan kontak yang sudah buruk sebesar 88,74,80 µΩ dikarenakan faktor operasi yang cukup tinggi (700 kali kerja) dan umur PMT yang sudah tua >20 tahun. Dan terdapat satu unit PMT bay IBT 1 sisi 150 kV yang memiliki nilai tahanan kontak yang masih cukup baik sebesar 66,63,62 µΩ dikarenakan perubahan nilai tahanan kontaknya disebabkan oleh faktor perubahan struktur penyangga mekanik PMT tersebut. Sedangkan 10 unit PMT lainnya memiliki nilai tahanan kontak yang masih dalam keadaan baik. Rekomendasi hasil dari evaluasi ini ialah perlu dilakukan penggantian PMT untuk bay cigereleng 1 dan dilakukannya perbaikan struktur penyangga mekanik pada PMT bay IBT 1 sisi 150 kV.

Resumo: O trabalho fala dos cotidianos de pessoas que passam pelo rótulo morador de rua. Por meio de uma etnografia numa praia do Rio de Janeiro, descrevo alguns espaços de convívio e, a partir dos mesmos, me inspiro a pensar alguns elementos daquela realidade, levando em conta a imensa complexidade que os movimentos da rua impõem à qualquer proposta reflexiva. Além disso, desenvolvo minha relação com campo em meio ao fazer musical. Explorando, assim, o conteúdo das músicas cantadas em campo e os exercícios coletivos de cantá-las. Isto permitiu dar importância ao movimento, que é um aspecto chave nestas reflexões. Por meio da categoria Exu – desenvolvida em religiões afro-brasileiras –, e alguns autores do interacionismo simbólico, entendo o morador de rua enquanto uma dimensão relacional. A partir daí é possível refletir sobre as condições na rua, a produção de conhecimentos derivados delas e a importância disso no exercício de recriação da cidade do Rio de Janeiro e seus espaços públicos. Palavras chave: morador de rua. Exu. morte. cotidiano. música   PRAIA DA AMENDOEIRA:STREET LIFE ON A CARIOCA BEACH  Abstract: The work talks about the daily lives of people who pass under the label homeless. Through an ethnography on a beach in Rio de Janeiro, I describe some living spaces and, from them, I get inspired to think about some elements of that reality, taking into account the immense complexity that street movements impose on any reflective proposal. In addition, I develop my relationship with the field in the middle of making music. Thus exploring the content of the songs sung in the field and the collective exercises of singing them. This allowed to give importance to the movement, which is a key aspect in these reflections. Through the category Exu - developed in Afro-Brazilian religions - and some authors of symbolic interactionism, I understand the homeless person as a relational dimension. From there, it is possible to reflect on the conditions on the street, the production of knowledge derived from them and the importance of this in the exercise of recreating the city of Rio de Janeiro and its public spaces.Keywords: homeless.

Resumo: Apresentando estudo de dupla autoria, situamos nosso trabalho de campo de pesquisa interdisciplinar sobre a história de um projeto de desenvolvimento emblemático do Brasil, o III Polo Petroquímico, localizado em Triunfo, no Rio Grande do Sul. Trata-se de um dos esforços de compreensão dos embates ocorridos nas décadas de 1970 e 1980: em contexto de ditadura civil-militar, articulações sociais em vários municípios do complexo lagunar Guaíba-Laguna dos Patos resultaram na proteção dos mananciais utilizados para o abastecimento da região metropolitana de Porto Alegre. Em percurso imagético resultante de trabalho empírico, nossa narrativa ressalta, a partir do rio Caí, o manancial em cujas margens situa-se o empreendimento industrial, suas principais referências geográficas e históricas em relação ao aglomerado urbano. Como resultado, sublinhamos a necessidade da conservação e disponibilização pública dos importantes acervos documentais existentes, política fundamental para a continuidade e melhoria do funcionamento das estruturas de proteção ambiental constituídas nesse complexo industrial e em seus similares.Palavras-chave: Narrativa visual. Relato de campo.

It is one of the efforts made to understand of the clashes that occurred in the 1970s and 1980s: in the context of the civil-military dictatorship, social articulations in several municipalities bordering the Guaíba-Laguna dos Patos lagoon complex resulted in the protection of the sources used to supply the metropolitan region of Porto Alegre. In an imagery path enabled by empirical acquisitions, our narrative highlights, beginning with the River Caí, the source on whose margins is located the industrial complex, its main geographical and historical references in relation to the urban complex. Consequently, we emphasize the need for the conservation and public availability of the important existing documentary collections, a fundamental policy for ensuring the continuity and improved functioning of the environmental protection structures constituted in this industrial complex and other similar complexes.Key-words: Visual narrative.

Published: October 2020

Resumen: Este artículo tiene como objetivo reflexionar sobre el concepto de territorialidades barriales en el área metropolitana de Montevideo, indagando en dos barrios específicos: Punta de Rieles y Malvín Norte, en los cuales el Programa Integral Metropolitano (PIM) de la Universidad de la República desarrolla sus actividades.Partiendo de la categoría de territorialidades barriales, este trabajo propone analizar los procesos de construcción de pertenencia e identidades a nivel barrial en la zona mencionada, desde una perspectiva de la integralidad y del diálogo de saberes, realizando observación participante y entrevistas a vecinos, trabajadores y usuarios de estos territorios. Entendemos a las territorialidades barriales como aquellas que se generan y aluden a relaciones cotidianas, pautadas por la proximidad, incluyendo los aspectos identitarios como centrales en su conformación. En este sentido, nuestro abordaje implica cuestionarnos sobre cómo ciertas territorialidades se condensan y se cristalizan en una escala barrial, a partir del habitar y el transitar cotidiano, en el área metropolitana de la ciudad.Palabras claves: Territorialidades barriales. Identidad. Área metropolitana  NEIGHBOURHOOD TERRITORIALITIES IN THE PROCESS OF IDENTITIES CONSTRUCTION IN THE METROPOLITAN AREA OF MONTEVIDEO  Abstract: The aim of this article is to discuss the concept of neighbourhood territorialities in the metropolitan area of Montevideo, investigating two neighbourhoods: Punta de Rieles and Malvin Norte, where the “Programa Integral Metropolitano” ( PIM - Universidad de la República) carries out its activities.Based on the concept of neighbourhood territorialities, this research analyses the construction of the sense of belonging as well as identities at a neighbourhood scale, from an integral perspective, incorporating the dialogue of different forms of knowledge, academic and non-academic knowledges, implementing participant observation and interviews to residents, workers and users of these territories. The concept of neighbourhood territorialities is defined as the ones being produced and described by daily relationships, established in the scale of proximity, and considering the identitaries aspects as fundamental in its structure. In this way, our approach involves questioning how some territorialities are created in the neighbourhood scale, based on the living experience and everyday circulation in the metropolitan area of the city.Keywords: Neighbourhood territorialities.

Published: October 2020

Resumo: Neste artigo, são apresentadas reflexões a partir de uma pesquisa etnográfica sobre o bairro da Vila Buarque, na região central de São Paulo. Historicamente ocupado por camadas médias e superiores da população paulistana, na última década o bairro tem vivenciado um afluxo de novos moradores hipsters (jovens de alto poder aquisitivo, vinculados a atividades profissionais tidas como criativas, alinhados a um espectro político mais progressista) e a inauguração de uma série de novos estabelecimentos comerciais (tais como bares, cafés, restaurantes e lojas de design) voltados a este perfil. Este fenômeno contraria a tendência histórica de deslocamento das elites para longe da região central da cidade, e é tomado como ponto de partida para a observação de como diversas referências globais de consumo e de modos de estar na cidade se refletem no contexto local.Palavras-chave: hipsters, cosmopolitismo, ubiquidade, consumo, cidade VILA BUARQUE BECOMES HIPSTER: GLOBAL CONCEPTS, LOCAL EFFECTS  Abstract: On this article, are discussed reflections based on an ethnographical research about Vila Buarque Neighborhood, in the central area of São Paulo. Historically occupied by middle-upper stratum of São Paulo population, over the last decade the neighborhood has become an residential option for new hipster residents (young people with high incomes, related to professional activities generally seen as creative, mostly politically progressive), and has witnessed the opening of several new businesses (such as bars, coffee shops, restaurants and design stores) targeted to these residents. This phenomenon happens in the opposite direction of the historical tendency of the elites leaving the central area of the city, and is taken as a starting point for the observation on how global references of consumption and ways of being in the city are reflected on the local context.Keywords: hipsters, cosmopolitanism, ubiquity, consumption, city
De Feira Nordestina a Centro de Tradições: a construção da identidade nordestina no Rio de Janeiro
Authors: Ramos Mello Vitor Rebello
Published: October 2020

Resumo: Este estudo etnográfico discute o processo de construção de identidades dos migrantes nordestinos na cidade do Rio de Janeiro, tendo como referência a transformação da Feira de São Cristóvão no Centro Municipal Luiz Gonzaga de Tradições Nordestinas. Parte integrante da dissertação Memórias repentinas: a construção poética do Nordeste pelos repentistas da Feira de São Cristóvão (RJ) defendida no Programa de Pós-Graduação em Memória Social/ UNIRIO[1], a presente análise faz uso da ideia de sociodinâmica da estigmatização para compreender as relações estabelecidas entre cariocas e nordestinos, bem como utiliza o conceito de lugares de memória para entender a importância da Feira enquanto bastião da cultura para a população migrante. Para tanto, fez-se um trabalho de campo entre 2010 e 2012, realizando observação não-participante e entrevistas semiestruturadas com atores sociais locais, além de pesquisa na hemeroteca digital do Centro Nacional de Folclore e Cultura Popular e revisão bibliográfica sobre o tema. Palavras chave: Feira de São Cristóvão.

As part of the dissertation Sudden memories: the poetic construction of the northeast region by the troubadours of the São Cristóvão Fair (RJ) defended in the Post-Graduation Program in Social Memory / UNIRIO, the present analysis makes use of the ideia of the sociodinamic of stigmatization to understand the relationships established between cariocas and northeasterners, using as well the concept of places of memory to comprehend the importance of the Fair as a bastion of culture for the migrant population. To this end, a fieldwork was performed out between 2010 and 2012, with a non-participant observation and semi-structured interviews with local social actors. Besides, researches were made in the digital library of the National Center for Folklore and Popular Culture and a bibliographic review about the topic. Keywords: São Cristóvão Fair.

Educación en tiempos de pandemia: tecnologías digitales en la mejora de los procesos educativos
Authors: Salinas Ibáñez Jesús
Published: October 2020

Las tecnologías digitales en el contexto de la pandemia COVID-19 han tomado relevancia al constituir, en muchos casos, el único nexo de los alumnos con las escuelas, trasladando los procesos de enseñanza al ámbito virtual. Al margen del enorme esfuerzo de muchos docentes, han quedado de manifiesto deficiencias crónicas del sistema educativo, entre ellas la baja competencia digital y, sobre todo, el aumento de la desigualdad en el acceso. Todo ello implica la necesidad de cambios en el sistema educativo en el tema digital -entre otros- y aparecen distintos interrogantes: ¿Qué tipo de respuesta damos a los problemas sobrevenidos? ¿Seguimos poniendo parches o aprovechamos la oportunidad para una verdadera transformación del sistema educativo? Estamos hablando de una oportunidad más para el rediseño radical de la enseñanza y la reinvención de la carrera docente que incorpore el desarrollo de la competencia digital.
Biwarped product submanifolds of a Kähler manifold
Authors: Taştan Hakan
Published: October 2020

We study biwarped product submanifolds which are special cases of multiply
warped product submanifolds in K?hler manifolds. We observe the
non-existence of such submanifolds under some circumstances. We show that
there exists a non-trivial biwarped product submanifold of a certain type by
giving an illustrate example. We also give a necessary and sufficient
condition for such submanifolds to be locally trivial. Moreover, we
establish an inequality for the squared norm of the second fundamental form
in terms of the warping functions for such submanifolds. The equality case
is also discussed.
Bounds on the domination number of a digraph and its reverse
Authors: Furuya Michitaka
Published: October 2020

Let D be a digraph. A dominating set of D is the subset S of V(D) such that
each vertex in V(D)?S is an out-neighbor of a vertex in S. The minimum
cardinality of a dominating set of G is denoted by ?(D). We let D?denote the
reverse of D. In [Discrete Math. 197/198 (1999) 179-183], Chartrand, Harary
and Yue proved that every connected digraph D of order n ? 2 satisfies
?(D)+ ?(D?) ? 4n 3 and characterized the digraphs D attaining the equality. In
this paper, we pose a reduction of the determining problem for (D)+(D?)
using the total domination concept. As a corollary of such a reduction and
known results, we give new bounds for (D)+(D?) and an alternative proof of
Chartrand-Harary-Yue theorem.
Developing countries and climate change policies
Authors: Todic Dragoljub , Grbic Vladimir
Published: October 2020

The paper considers the question of the position and role of developing
countries in the contemporary law and policy of climate change. The basic
thesis in this paper is that the position of developing countries is defined
in relevant international legal documents, but that significant differences
between individual categories of developing countries are not clearly
emphasized. In this sense, the first part of the paper is focused on the
problems of defining of the notion of developing countries. The second part
gives an overview of the specific rights and obligations of developing
countries within the framework of the existing system established by United
Nations Framework Convention on Climate Change and the Kyoto Protocol. In
particular, it highlights the content and dilemmas in the interpretation of
the principle of common but differentiated responsibilities. The third part
of the paper presents some common features of developing countries that are
of relevance for climate change. It provides an overview of some features and
elements of the policies of individual countries (members of non- Annex I,
small island countries, least developed countries and developing countries
which are the largest emitter of GHGs).

Several bacterial cultures: Bacillus licheniformis (MO1), B. pumilus (MO2),
and B. amyloliquefaciens (MO3), isolated from manure; B. megatherium ZP6
(MO4) isolated from maize rhizosphere; Azotobacter chroococcum Ps1 (MO5) and
Pseudomonas fluorescens (MO6), were used to test the influence of plant
growth promoting rhizobacteria (PGPR) on seed germination and germination
rate of field dodder (Cuscuta campestris Yunk.). Also, to examine the effect
of host seeds on germination and initial growth of seedlings of field dodder
plants in the dark and under white light, the seeds of four host plants were
used (watermelon, red clover, alfalfa and sugar beet). Germinated seeds were
counted daily over a ten-day period and the length of seedlings was measured
on the final day. The results show that treatments MO3, MO4 and MO6 had
inhibitory effects (15%, 65% and 52%, respectively), while treatments MO1,
MO2 and MO5 had stimulating effects (3%, 3% and 19%, respectively) on seed
germination of field dodder. The data for host seeds show that light was a
significant initial factor (83-95%, control 95%) for stimulating seed
germination of field dodder plants, apart from host presence (73-79%, control
80%).
