AVALIAÇÃO EXTERNA E AUTONOMIA DOCENTE: o SMAEF como meio de reprodução da cultura por resultados
Authors: Cunha Niágara Vieira Soares , Silvestre Pedro Henrique , Maia Francisco Eraldo da Silva , Dos Santos Sarah Galdino , De Oliveira Talisson Mota
Published: December 2020

Esta pesquisa traz à tona um estudo a respeito das avaliações externas e suas implicações na autonomia e profissão docente. A referência é o município de Russas, localizado na Região do Vale do Jaguaribe, no estado do Ceará. Analisa as implicações do Sistema Municipal de Avaliação do Ensino Fundamental (SMAEF) do município de Russas-CE na autonomia e valorização do trabalho docente. O paradigma foi o marxismo investigativo com o método Materialismo Histórico Dialético. Foram entrevistados 57 professores da rede de ensino do município de Russas-CE, no período de abril a junho de 2020, por meio de Formulário Eletrônico do Google Forms. Utiliza-se a análise de discurso. De 57 entrevistados, 50 informaram que o nível de exigência por resultados que recai sobre os docentes, por meio da rede de ensino, é alto, enquanto apenas 7 informaram que a exigência é razoável. Somado a isso, com uma política educacional voltada com afinco para as avaliações em larga escala, 73,7% dos entrevistados informaram que a autonomia do trabalho docente foi reduzida com a política do SMAEF. A autonomia e a valorização do trabalho docente entram por uma via de supressão. Por fim, resta saber que tipo de crianças e adolescentes se busca formar com base nessa lógica mercantilizadora e meritocrática na qual a educação pública se transforma a cada dia. Para que as desigualdades de oportunidades não perpetuem, é necessário modificar esse cenário e elevar a problemática das políticas de avaliação em larga escala ao patamar político, histórico e social.
INTERNET, PANDEMIA E FORMAÇÃO DE PROFESSORES EM EDUCAÇÃO FÍSICA. Experiências de constituição de subjetividades ativas
Authors: Ruiz Mariel , Pisano Casala Maria Paula , Ríos Teresita
Published: December 2020

Este texto sintetiza um trecho de uma investigação em curso sobre as experiências dos alunos e a produção de saberes corporais na formação inicial de professores de Educação Física da Universidade Nacional de Luján, no contexto do atual isolamento social, preventivo e obrigatório. É uma análise dos usos da Internet dentro da rede social Facebook (FB), buscando compreender como e de que forma seu uso contribui para a conformação das subjetividades de ensino. Parte-se de uma abordagem sócio-crítica da realidade a ser investigada, assumindo a responsabilidade de construir o conhecimento como produto do diálogo entre múltiplas perspectivas e posições de sentido e verdade. Considerando as postagens de alunos, professores e outros, como discursos que contribuem para a conformação de identidades e/ou papéis docentes, em um contexto e desde o início de sua carreira (LITWIN, 2005; CASABLANCAS, 2017; MAGGIO, 2018) incluindo a digitalidade como um novo cenário articulador de saberes e identidades (RUIZ, GANZ, CASABLANCAS, 2020). A observação não participante tem sido usada como uma estratégia útil de coleta de informações para a descrição das interações em um grupo fechado de FB. A análise revelou uma utilização particular da referida plataforma, dando origem a uma multiplicidade de sujeitos ativos, que produzem conhecimentos ligados ao ensino, demonstrando a criação de novas, outras e mesmo desconhecidas identidades docentes.
DESIGN PROCESS OF DME STORAGE SYSTEM AS ASSEMBLY PARTS OR MAINTENANCE SPARE PARTS INVENTORY IN OFFSHORE OIL DRILLING PIPING SYSTEM
Authors: Cahyati Sally , Mahendra Daniel Rizky
Published: December 2020

Discharge Manifold Equipment (DME) is an output pipe from a pump that bears an essential role in a piping system in offshore oil drilling, so it is a must to assure good bears condition whenever used. It is not an easy thing because DME is a significant and heavy component. Also, unfavourable conditions of offshore climate can accelerate its corrosion. Storage with the modular rack uses an offshore container certified DNV 2.7-1 / EN 12079 will be designed to fulfil those needs. The storage has an important role as an element in inventory, both the storage system for assembly parts or maintenance spare parts. This storage will be design using 4 (four) phases from VDI 2221 methods, namely; task clarification, conceptual design, embodiment design, and detailed design. Hydraulic power will be added to the system to support the piston movement so that the storage rack can be moved automatically by the hydraulic system. This storage has given the best solution for a systematic storing DME in the piping system of offshore oil drilling.
DESIGN MODELING OF SAVONIUS-DARRIEUS TURBINE FOR SEA CURRENT ELECTRIC POWER PLANT
Authors: Metheny Boris , Permatasari Rosyida , Annas Muhammad Sjahrul
Published: December 2020

Turbines convert the kinetic energy of ocean currents into electrical energy produced by the sea current electric power plant. This study aims to design a power generator turbine modeling that is carried out using the Computational Fluid Dynamic (CFD) approach by comparing the geometric performance based on the angle of attack and the Tip Speed Ratio (TSR) value of the Savonius-Darrieus Turbine. Having done several trials and errors during collecting the data, the value of the TSR 1.427; 2.853; 4.28; 5; and 5.7 is proposed. Here, the NACA 0018 series has been adopted on the current design of Savonius-Darrieus Turbine. The turbine has three blades, length of the span 357 mm, the diameter of turbine 428 mm, and length of the hydrofoil chord 40 mm. Effect of various angle of attacks from 0°up to 10° has been taken into account in the computational to obtain the coefficient power for each variation. The results revealed that the turbine with an angle of attack of 5°and TSR value of 5.0 has higher power coefficient value by 0.469 as compared with its angle of attack of 10°. It should be noted here that the increase of the angle of attack up to 10° resulted in a significant reduction of the power coefficient value of 0.206 as the value of TSR about 4.28. The addition of the Savonius Rotor results in increasing efficiency of the turbine for sea current applications.

Você já parou para pensar como uma fotografia pode ser paradoxal? Que sentimentos podem surgir quando se está diante de uma imagem, o olhar por ser congelado, você pode fixar-se-a ela por segundos... minutos… horas… Para Samain 2003), a fotografia pode ser comparada a uma múmia, ela pode estar imóvel há anos,  enclausurada em sua urna, silenciosa, ou seja muda, ela não mais irá falar, porém no entanto nossa imaginação, mil palavras podem surgir. Neste momento o autor menciona  o que podemos classificar de “discursos do silêncio” de uma determinada imagem  - “Discurso por ela provocados, que surgem dos fundos da nossa interioridade, da caverna obscura de nosso pensamento. Pois, se é verdade que olhamos para ela, também ela olha para nós, nos aponta, nos questiona, nos perscruta, nos desvenda, nos desnuda.” (Samain, p. XVIII, in. ACHUTTI, 1997).Para esse estudo a peça de teatro “Frida Kahlo, à revolução” será o foco. O espetáculo vem sendo apresentado nos palcos, desde 2009, quando foi criado conjuntamente a Companhia de teatro, intitulada de Cia Dramática.  Quem fica à frente da companhia é quem protagoniza a personagem Frida, a atriz Juçara Gaspar. Seu parceiro e colega de cena, é o músico e ator Luciano Alvez.

Dimensioning the relationship between availability and data center energy flow metrics
Authors: Bezerra Thiago Valentim , Leonardo Wenderson De Souza , Júnior Gabriel Alves de Albuquerque , Callou Gustavo Rau de Almeida
Published: December 2020

The advancement of technology and the growing number of applications available to network users have increased the demand for services hosted in cloud environments. In 2020, more than 4 billion of people access these services through the Internet, a value 7% higher in comparison to the same period in 2019. To support the demand for such services, an environment that provides such conditions for applications available whenever needed has grown in importance. These environments are generally available from large data centers, which consume large amounts of electricity to provide such demand service capacity. In this context, this work proposes an integrated and dynamic strategy that demonstrates the impact of the availability on the energyconsumption of the devices that compose the data center system architecture. In order to accomplish this, colored Petri net models were proposed for quantifying the cost, environmental impact and availability of the electric energy infrastructure ofdata centers. The models presented in this work are supported by the developed prototype. Two case studies illustrate the applicability of the proposed models and strategy. Significant results were obtained, showing an increase close to 100% in the system availability, with practically the same operational cost and environmental impact.

Este artigo propõe analisar duas exposições pelo ponto de vista de suas curadorias e de críticas recebidas. Enquanto Aracy Amaral, curadora da mostra “Além fronteiras”, da 8ª Bienal do Mercosul (Porto Alegre, 2011), recebia críticas pelo seu projeto curatorial; alguns anos mais tarde, a consagrada curadora publica uma crítica contundente relativa “À nordeste” (São Paulo, 2019), exposição que teve como curadores Bitú Cassundé, Clarissa Diniz e Marcelo Campos. Serão confrontados argumentos que foram elaborados tanto para a realização das propostas curatoriais quanto de suas críticas, propondo uma reflexão sobre mudanças, nem sempre perceptíveis, que ocorrem na arte contemporânea. Abstract This paper proposes to analyze two exhibitions from the point of view of their curator-ships and criticisms received. While Aracy Amaral, curator of the “Além fron-teiras” at the 8th Mercosul Biennial (Porto Alegre, 2011) was criticized for her cura-torial project, a few years later, the consecrated curator published a overwhelming criticism regarding the “À Nordeste” (São Paulo, 2019), exhibition curated by Bitú Cas-sundé, Clarissa Diniz and Marcelo Campos. Arguments that were elaborated both for the realization of curato-rial proposals and for their criticisms will be confronted, pro-posing a reflection on changes, not always noticeable, that occur in contemporary art.

O artigo discute o estudo da cultura visual a partir dos documentos históricos inventários, testamentos e autos de partilha, bem como da localização e análise de exemplares subexistentes em instituições museais. Para tanto, buscamos subsídios e apontamos como principal exemplo, os estudos e metodologia utilizada pela historiadora da arte baiana Maria Helena Ochi Flexor na publicação intitulada O Mobiliário Baiano: Séculos XVIII e XIX (1970) e suas reedições, Mobiliário Brasileiro – Bahia (1978) e Mobiliário Baiano (2009). Desse modo, verificamos que os documentos são riquíssimas fontes para compreensão de diversos aspectos sociais, em especifico o mobiliário, os estilos artísticos vigentes e os materiais comuns empregados. AbstractThe paper discusses the study of visual culture based on historical inventories, wills and sharing documents, as well as the location and analysis of sub-existing examples in museum institutions. To this end, we sought subsidies and pointed as the main example, the studies and methodology used by bahian art historian Maria Helena Ochi Flexor in the publication entitled The Bahian Furniture: 18th and 19th Centuries (1970) and its reissues, Brazilian Furniture- Bahia (1978) and Bahian Furniture (2009). Thus, we find that the documents are very rich sources for understanding various social aspects, in particular the furniture, the current artistic styles and the common materials employed.
Epistemologia e arte: a questão do conhecimento estético em Francis Ponge
Authors: Perius Cristiano
Published: December 2020

Este ensaio analisa a relação entre arte e conhecimento a partir da obra poética de Francis Ponge. O teor cognitivo está na iniciativa de edificação de uma mathesis singularis a partir do contato com os objetos em sua apreensão direta. A emoção poética, como fato original e causa do poema, é conduzida à descrição do objeto até a forma de uma lei estética apta à configuração objetiva do mundo. A forma estética visa a adequação entre as palavras e as coisas a partir de um recuso semiótico da linguagem, a saber, a onomatopéia. No interior do projeto cognitivo e intencional de Francis Ponge, a onomatopéia é o recurso que define o objeto, seguido por uma descrição fiel aos objetos em sua manifestação concreta. À luz da experiência poética de Francis Ponge, que correlaciona explicitamente a relação entre arte e conhecimento, estão abertas as possibilidades de pensar o conhecimento estético a partir de outras artes e artistas, como a pintura de Cézanne, entre outros. AbstractThis essay analyzes the relationship between art and knowledge from the poetry of Francis Ponge. The cognitive content is in the initiative of building a mathesis singularis from the contact with the objects in its direct apprehension. Poetic emotion, as the original fact and cause of the poem, is led to the description of the object into the form of an aesthetic law apt to the objective configuration of the world. The aesthetic form aims at matching words and things through a semiotic refusal of language, namely onomatopoeia. Within Francis Ponge's cognitive and intentional project, onomatopoeia is the defining feature of the object, followed by a faithful description of the objects in their concrete manifestation. In the light of Francis Ponge's poetic experience, which explicitly correlates the relationship between art and knowledge, the possibilities of thinking aesthetic knowledge from other arts and artists, such as Cezanne's painting, among others, are open.
Onde estão os negros? Apagamentos, racialização e insubmissões na arte brasileira
Authors: Simões Igor Moraes
Published: December 2020

A presença de sujeitos negros na arte brasileira e seus apagamentos constituem paralelo direto aos mesmos processos de localização desses sujeitos na vida do país. Estamos imersos em uma história da arte branca e a empreitada passa por rever as palavras, imagens, displays e reservas técnicas que ecoam um profundo desconhecimento quando projetam perguntas como: Onde estão os negros? Cabe ainda a tarefa de pensar as modernidades e suas reafirmações baseadas em princípios que ecoam mestiçagens, mitos e fantasmas que ainda assombram a possibilidade de histórias que correspondam à definitiva e numericamente maioria de sujeitos negros na sociedade brasileira.AbstractThe presence of blacks in Brazilian art and the intentional deletion of their presence can be directly related to the processes that have determined their role in society. We are still immersed in a white-oriented art history; thus, our endeavor is to reconsider the words, images, displays and collection storage spaces that reverberate widespread ignorance when raising questions such as: Where are the blacks? We have to ponder over modernities and their reaffirmations, based on principles echoing mestizaje, myths and ghosts that still haunt possible stories that represent the definitive and vast majority of black people in Brazilian society.

Published: December 2020

The main aim of this study is to critically analyze the effects of institutions on economic growth on the basis of a deeply literature review with a technological point of view. This study found that culture, traditions, tacit knowledge, openness to innovations are the outstanding points in new century and we assert that for increasing positive effects of institutions in the long term there should be a model for management and governance of business of institutions that is the whole economy in the digital macroeconomics. In the era of the upcoming industry 4.0, smart cities and e-government paradigms there should be integration of IT and business processes via a valid management and governance model. With the assumption that innovation digestion and cutting-edge IT capability of institutions have positive effect on their profitability and competency in the market, COBIT model is found to be a valid and sustainable framework for effective and efficient institutional set-ups that provide a sustainable platform for economic value creation cycle.

Introducción: la bacteriemia en pacientes cirróticos es frecuente y se asocia con una alta mortalidad y hospitalización prolongada. Este estudio describe las características demográficas, clínicas y de laboratorio en pacientes con cirrosis hepática y bacteriemia en un hospital de cuarto nivel.
Métodos: estudio observacional de cohorte retrospectiva. Incluyó pacientes con cirrosis hepática y bacteriemia entre el 1 de enero de 2010 y el 31 de diciembre de 2017 en el Hospital Pablo Tobón Uribe de Medellín, Colombia. Se recogieron variables demográficas, clínicas y de laboratorio. Se estimó la supervivencia durante el tiempo de hospitalización y hasta 30 días desde el diagnóstico de bacteriemia.
Resultados: se hallaron 78 pacientes con cirrosis y bacteriemia. La media de edad fue de 65 años, 66,7 % fueron mujeres. Las principales etiologías de la cirrosis fueron: criptogénica (30,8 %) y esteatohepatitis no alcohólica (EHNA; 19,3 %). La principal fuente de infección fue la vía urinaria (24 %), seguida de colangitis (23 %) y la bacteriemia espontánea (19 %). Los bacilos gramnegativos (BGN) representaron la mayoría de los aislamientos (67,9 %). La prevalencia de multidrogorresistentes (MDR) fue de 25,6 % y el uso adecuado de antibiótico empírico fue de 80,8 %. La mortalidad a 30 días fue de 11,5 %. Como mejores predictores de mortalidad se encontraron la puntuación Child-Pugh y Model for End-stage Liver Disease (MELD) al ingreso con área bajo la curva ROC (AUROC) de 0,79 (p = 0,008) y 0.72 (p = 0,042), respectivamente. Conclusiones: los hallazgos permiten conocer las principales características de los pacientes con cirrosis que desarrollan bacteriemia en nuestro medio. Se encontró un número considerable de infecciones MDR. Los pacientes con un grado avanzado de la cirrosis son los que presentan un mayor riesgo de mortalidad.
CHEMICAL BATH DEPOSITION OF PbS THIN FILMS
Authors: ÖNAL Metehan , ALTIOKKA Barış
Published: December 2020

In the current study, thin films of PbS were fabricated at 35 ᵒC bath temperature via chemical bath deposition (CBD) method. During the experiment, 0.1460 M NaOH and 0.0085 M Pb (NO3)2 were dissolved in 100 ml of deionized water and 0.510 M thiourea was inserted. Thiourea, which is used as the ligand source, was inserted to the solution at zero, one point five, three, six and nine minutes intervals, in 10 parts, unlike conventional production methods. When the first sample was produced, thiourea was inserted to the solution at one time and compared with other samples. XRD patterns were used in determining the structural features of the produced films. XRD patterns show that peak density increased significantly when thiourea was inserted at intervals of three, six and nine minutes. A scanning electron microscope (SEM) was utilized in analyzing the morphological properties of the films. When SEM images were examined, it was observed that when thiourea was inserted at different time intervals, there were no pinholes.
PREDICTION OF PROXIMATE ANALYSIS AND PROCESS TEMPERATURE OF TORREFIED AND PYROLYZED WOOD PELLETS BY NEAR-INFRARED SPECTROSCOPY COUPLED WITH MACHINE LEARNING
Authors: KASAPOĞLU ÇALIK Meltem , AYDIN Ebubekir Sıddık , YÜCEL Özgün
Published: December 2020

Near-Infrared (NIR) Spectroscopy is a time and cost-effective method to characterize the materials in the food, petrochemical, pharmaceutical, and agricultural industries. Proximate analysis of the carbon-containing materials and investigating the effectiveness of the heat treatments on the material are a particularly time-consuming process. This work presents the four regression methods, i.e., decision tree regression, support vector regression and two versions of ensembles of decision trees to predict the proximate analysis of biomass and heat treatment temperature. Thus, effective method has been proposed to reduce experimental effort and present the characterization of heat-treated biomass feedstock theoretically. Prediction results show that SVR and ENS2 regression methods calibrating the NIR spectra to the values of wood pellet properties achieved good performance with the coefficient of determination (R2) of 0.880- 0.984 and RMSE of 0.444- 5.308 for ash and volatile matter. This study suggests that machine learning-based regression methods with integrated NIR spectroscopy of biomass is promising as an alternative method for rapid characterization. Another possible application of the current study is that it can be used for processed fuel recognition prior to a fully automated fuel quality assessment system in the biomass industry.

Published: December 2020

Object: To compare the clinical data of sternotomy and left intercostals
incision, combined with the literature, to provide the best surgical
incision for committed subarterial ventricular septal defect（DCS-VSD）.
Methods: From July 2016 to July 2020, a total of 117 cases of occlusion
surgeries for DCSVSD, which guided by transoesophagel
echocardiography(TEE) were completed, including 34 cases with sternotomy
incision and 83 cases with left intercostal incision. Statistics and
analysis of the operation and follow-up. Results: 115 cases successfully
occluded, the successful rate was 98.29%, and 1 case failed in each
group. Pericardial effusion occurred in 5 children after the drainage
device was removed, and the pericardial effusion disappeared after
diuretic treatment. There was no statistical difference between the two
groups in operation time, occlusion time, thoracotomy time and
postoperative hospital stay. All the children recovered and were
discharged from the hospital, and were followed up for 2-30 months after
operation. Conclusion: TEE-guided intercostal DCS-VSD occlusion is safe
and effective. There is no statistical difference between two approach
with the operation time, chest opening and closing time, occluder
placing time, and postoperative hospital staying. At the same time, the
surgical incision by intercostal incisionis smaller and the operation
invasion is less, it is a surgical approach which worth to develop.
Overproduction of ABA in rootstocks alleviates salinity stress in tomato shoots

Published: December 2020

To determine whether root-supplied ABA alleviates saline stress, tomato
(Solanum lycopersicum L. cv. Sugar Drop) was grafted onto two
independent lines overexpressing the SlNCED1 (9-cis-epoxycarotenoid
dioxygenase) gene (NCED OE) and wild type rootstocks. After 200 days of
salinity irrigation (EC = 3.5 dS m-1), plants with NCED OE rootstocks
had 30% higher fruit yield, but root biomass and lateral root
development was reduced. Although NCED OE rootstocks upregulated
ABA-signalling (AREB, ATHB12), ethylene-related (ACCs, ERFs), aquaporin
(PIPs) and stress-related (TAS14, KIN, LEA) genes, downregulation of PYL
ABA receptors and signalling components (WRKYs), ethylene synthesis
(ACOs) and auxin responsive factors occurred. Elevated SlNCED1
expression enhanced ABA levels in reproductive tissue while ABA
catabolites accumulated in leaf and xylem sap suggesting homeostatic
mechanisms. NCED OE also reduced xylem cytokinin transport to the shoot
and stimulated foliar 2-isopentenyl adenine (iP) accumulation and phloem
transport. Moreover, increased xylem gibberellin GA3 levels in growing
fruit trusses was associated with enhanced reproductive growth. Improved
photosynthesis without changes in stomatal conductance was consistent
with hormone-mediated alteration of leaf growth and mesophyll structure,
which combined with lower assimilate requirement in the roots and
systemic changes in hormone balances could explain enhanced vigour,
reproductive growth and yield under saline stress.
Drawing up a collaborative contract: Amino acid cross-feeding between inter-species bacterial pairs
Authors: Kelly Erin , Fischer Alexandria , Collins Cynthia
Published: December 2020

Synthetic microbial communities have the potential to enable new
platforms for bioproduction of biofuels and biopharmaceuticals. However,
using engineered communities is often assumed to be difficult because of
anticipated challenges in establishing and controlling community
composition. Cross-feeding between microbial auxotrophs has the
potential to facilitate co-culture growth and stability through a
mutualistic ecological interaction. We assessed cross-feeding between 13
Escherichia coli amino acid auxotrophs paired with a leucine
auxotroph of Bacillus megaterium. We developed a minimal media
capable of supporting the growth of both bacteria and used the media to
study co-culture growth of the 13 interspecies pairs of auxotrophs in
batch and continuous culture, and on semi-solid media. In batch culture,
eight of thirteen pairs of auxotrophs were observed to grow in
co-culture. We developed a new metric to quantify the impact of
cross-feeding on co-culture growth. Six pairs also showed long-term
stability in continuous culture, where co-culture growth at different
dilution rates highlighted differences in cross-feeding amongst the
pairs. Finally, we found that cross-feeding-dependent growth on
semi-solid media is highly stringent and enables identification of the
most efficient pairs. These results demonstrate that cross-feeding is a
viable approach for controlling community composition within diverse
synthetic communities.

The political (in)stability of the central American countries
Authors: Dujic Ivan
Published: December 2020

The paper analyses a correlation between the political (in)stability of the
Central American countries and the inequality of the countries in relation
to the development of capitalism from the aspect of international politics
and economics in the case of the Central American countries. Such a status
of the Central American countries is opposed to the fact that they have
achieved equality in public international law. The Introduction also
indicates that political stability depends on functional public authorities,
and the success in macroeconomic policy. The main part of the paper deals
with the factors which led to political (in)stability during the Cold War
and afterwards. The internal factors include lack of communication and trust
between government and opposition, weak democracy, serious violations of
civil and political rights, dangerous activities of paramilitary forces,
economy depending on illicit drug dealers, the underdeveloped legal system
as well as the lack of modern, equipped police. The above shortcomings refer
especially to Guatemala, Honduras, and Nicaragua. This is verified by their
ranking in the Human Development Index. On the other hand, countries like
Belize, El Salvador, Costa Rica and Panama are among higher-ranked
countries. The most important external factor is the US economic and
political impact. In that sense, capitalism can be seen as a recognisable
stabilising force due to its ability to adapt itself to occasional economic
and political crises. However, China?s growing economic, technical and
technological influence on the world could determine a different course of
capitalism?s development, as opposed to the US efforts to maintain a leading
position in defining the role of capitalism in international relations. The
author concludes that these countries can get free from the US influence and
become politically stable, provided that China determines the course of
future capitalism?s development.
Hostile emotions and the problem of their collectivity
Authors: Jovanov Rastko
Published: December 2020

The paper discusses the nature of negative (hostile) emotions and their role
in the cultural, i.e. the ethical world of life. A distinction is made
between positive and negative emotions on the basis of their orientation
towards the outside world and towards the bearer of emotional states. It is
claimed that the bearer of negative emotions, unlike positive ones, becomes,
in fact, their hostage over time, and that he is intentionally turned
towards himself as an object instead of towards other people. I also claimed
that this kind of intentionality is ?empty?, because the object of intention
exists only in the memory of the subject of intention. In the end, I
presented arguments in favor of the existence of collective hostile emotions
that can have a positive meaning in a certain social context, which is
characterized by obvious social inequality and injustice.
The explanatory gap problem and Papineau’s phenomenal concepts strategy
Authors: Ristic-Rankovic Sanela
Published: December 2020

The main purpose of this article is to analyze David Papineau?s influential
perceptual model of phenomenal concepts in order to respond to the
explanatory gap problem. Those are special kind of concepts which we use to
refere to phenomenal properties of our own experience. Such concepts are
formed when the subjects initially perceive relevant entities, they get
stored into memory, and become re-activated at each coming encounter. Their
distinctive feature is the non-existence of a priori connection with other
concepts we possess. When we think in non-phenomenal concepts we do not have
the same feeling as when we think in phenomenal concepts. This is the cause
of our assumption that feelings are somehow different than physical
properties. This situation of two different modes of presentation of the
same entity which develop the illusion of two different entities Papineau
calls the antipathetic fallacy: It is the source of the dualist
intuitions which encourage the impression of an explanatory gap and lead us
to persistently reject the identity of mental and physical. Once we grasp
the structure of phenomenal concepts we will understand the origin of those
intuitions as well as the fact that they do not give us enough reasons for
doubt in physicalism.

Agility amid uncertain circumstances is key to all-across sustainable industries, and the construction industry depends heavily on projects as potent drivers to their operational activities regardless of projects’ hardwired constraints—shipment, resistance to risks— to affect Key Performance Indicator (KPI). PT ABX as one of Indonesian precast-concrete manufactures is the object of this research aiming to find precautionary strategies for controlling disruptions to concrete supply chain in construction projects. It takes into account such supply-chain disruptions, and therefore, the two-layered model of House of Risk (HOR) to subsume risks identification and risks control is applicable for minimizing possible disruptions. It finds risk events some of which are classified as critical risk events and preventive actions against risks. The findings contribute to working framework for managers responsible for applying effective strategies for preventing such disruptions.

This study concerns the finding of an effective operational equation relating the measured absorpbance (or O.D. - optical density) in a spectrophotometer of the suspended cells of microalgae to their cell density (c.d.) in culture in order to construct calibration curves for use in culture operations. The microalgae examined were the chlorophyte Nephroselmis sp., the dinophyte Amphidinium carterae and the filamentous cyanobacterium Phormidium sp. Wavelengths of 430 and 680 nm were selected that correspond to chlorophyll-a peaks of their absorption spectra were used and additionally 750 and 570 nm where absorbance was not peaked. From all equations extracted best fitness with strong predictive values were those of a logarithmic type: O.D.=0,9328*ln(c.d.)-14,108 (R2=0,9943) at 680 nm for Nephroselmis, a power equation: O.D.=0,0000009*(c.d.)0,9195 (R2=0,9936) at 680 nm for Amphidinium and a polynomial second order: O.D.=0,9869(c.d.)2+2,4393(c.d.)+0,2666 (R2=0,9737) at 570 nm for Phormidium.

National Education Policy-2020 visualized to provide a quality education which is beneficial to meet the growing economy in India. The new policy is aiming to achieve majorly three aspects such as highest quality, equity, and integrity in the education system from schooling to higher education. Commerce and management education play an important role in the country’s economy as it effects all the sectors like manufacturing, service industry, research and development, banking etc. in all the field finance is the nerve system and knowledge to manage finance is dealt with commerce and management. The current education policy existing in India are concentrating majorly on theoretical aspects which lacks the practical training among the students i.e., the major drawback for meeting the global job opportunities. Therefore, the National Education Policy-2020 is aiming to develop creative potential, skill and analytical thinking which are the need in the global job market is. Hence all the curriculum of commerce and management should be redesigned based on the outcome based education, where the stakeholders can know in prior what they are going to learn and how it is beneficial to develop themselves to meet the future changes in economy.

The optimization conditions of preparation of activated carbons based Balanites aegytiaca shells by chemical activation was investigated. The effects of three parameters of preparation namely, the activation temperature (600-800 °C), impregnation ratio (1:4-3:8) and residence time (60-120 min) were thoroughly studied on the activated carbon yield (Yld, Y1), iodine number (ION,Y2) and methylene blue number (MBN, Y3) using the Methodology of Experimental Design (MED). The analysis of variance (ANOVA) under the experimental domain revealed that, the activation temperature of 800 °C, residence time of 02hrs and impregnation ratio of 1:2 were the optimum conditions of preparation leading to activated carbon yield of 23.0%, iodine number of 889.0 mg/g and methylene blue number of 9.7 mg/g. The polynomial equation showed that the three parameters were both synergetic and antagonistic on the responses retained. The higher values of iodine numbers obtained alongside the experimental matrix is an indication that the activated carbons so prepared were mainly microporous.
A Heavily Giant Calcified Hydatid Cyst of the Liver with Thoracic Involvement Presenting as an Abdominal Mass (A Very Rare Case Report): The Role of Imaging
Authors: Danfulani Mohammed , Musa Abubakar , Gele Ibrahim Haruna
Published: December 2020

Hydatid disease is common in the tropics. It is caused by infection with the larval stage of Echinococcus tapeworm. Infestation of humans, who are accidentally the intermediate host, occurs from ingestion of water or food contaminated by fecal material of definitive host (dog, wolves, deer, sheeps). The most frequent organ of involvement is the liver in up to 70%, followed by the lung about 18% and with a lower reported incidence in other organs or tissues in the body. It primarily affects the liver and shows typical imaging findings. However clinical presentation varies widely and is non specific. Thus, imaging plays an important role in diagnosis of hydatid diseases. Ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI) can depict hydatid disease. The imaging methods used depend on involved organ and the radiological findings which range from purely cystic lesions to completely solid appearance. We report a very rare case of a calcified huge hydatid cyst in a 42 year old patient to buttress the role of imaging in management of such cases.
Improvements of the US BI-RADS Assessment – A Necessity for a Non-Invasive Positive and Differential Diagnosis of Breast Cancer. Application of the New Full Breast Ultrasonography Concept
Authors: Colan-Georges Aristida
Published: December 2020

Objective: Despite the engineering progress, the diagnosis of breast cancer (BC) is unsatisfactory due to less specific descriptors and non-anatomical scanning and interpretation, proving that physicians lag behind technology. We aimed to improve the noninvasive positive and differential diagnosis of BC using modern technology applied to the new integrative concept of Full Breast Ultrasonography (FBU): anatomical radial scanning, color Doppler and Strain Sonoelastography (SE).

Methods: We analyzed retrospectively 1841 consecutive FBUs in 1333 patients from screening, diagnosis, or follow-up, in two centers. We searched three descriptors: the ductal connection of the lesions, the incident angle of the plunging artery, and the SE (Ueno score). We compared the initial BI-RADS assessment with pathological reports or follow-up examinations of benign findings.

Results: Radial scanning and ductal connection provided a standardized examination of the entire breast, with 100% sensitivity, early detection, precise location, and easy follow-up. We found no correlation BC-Density-Age, but a significant association BC - Benign pathology. The benign lesions, usually multiple, associated the proliferative and secretory types. The incident angle of the plunging artery was the best descriptor for the BC mass-type and associated with a score 4 or 5 Ueno led to PPV of 97.01%, specificity of 99.67%, and accuracy of 99.69%. Inflammatory BC illustrated high glandular strain and diffuse hyperemia.

Conclusion: FBU had optimal accuracy, independent of the mammographic model, in screening and diagnosis. The vascular angle correlated with strain SE (adapted to the breast heterogeneity) raised the specificity and is recommended for inclusion in US BI-RADS.
New Thermodynamics: Inelastic Collisions and Cosmology
Authors: Mayhew Kent W.
Published: December 2020

The sciences have evolved around elastic collisions although most collisions are inelastic. Elastic collisions allow for simpler mathematical modelling, that may not be particularly suitable for cosmology.

Inelastic collisions create photons. This has led to consideration of an ensemble of inelastic collisions producing CMB. This will further lead to brief discussions concerning the nature of dark matter, and dark energy. This will then be followed by a simpler analogy concerning the creation of Hawking’s radiation.

A consequence of collisions being inelastic is that as a mathematical contrivance, entropy may only be an approximation when applied to the real world. And this fits well with this author’s “New Thermodynamics”.

Published: December 2020

This paper aims to demonstrate the effectiveness of the Conversation Analysis Tool in the context of teaching world literature to senior students majoring in English philology. The authors present their experience of undertaking a three-month online course “Constructive Classroom Conversations: Mastering Language for College and Career Readiness,” hosted by Stanford University, and discuss the benefits of applying this tool at universities. The study describes the basic mechanisms of the Conversation Analysis Tool aimed at developing specific communication skills in students of English for Speakers of Other Languages. The central research question is whether this method is as feasible for teaching literature as it is for language classrooms. The authors demonstrate their takeaways from applying this technique in teaching world literature, namely, analyzing literary dialogues in different classroom activities. The research findings indicate that the Conversation Analysis Tool is an efficient method for the formative assessment of senior students in the world literature classroom. This technique helps students reveal the pragmatic features of fiction dialogues, the writer’s narrative intentions, and the reader’s expected reception. The suggested method also demonstrates students’ progress in the studied topics and identifies possible gaps in mastering the educational content. The significance of the study extends beyond the specified context, as the search for novel instruction techniques targeted at improving communication skills in the 21st-century globalized world is relevant for any educational sphere. Consequently, the research findings of this paper can be applied in different teaching settings.
Language Maintenance and Language Shift among Keralites in Oman

Published: December 2020

This study explores the current status of language maintenance (LM) and language shift (LS) among Keralites, popularly known as ‘Malayalees,’ living in Oman. It analyses the leading factors that affect language maintenance and language shift: a particular focus is given to identifying the various domains in which language maintenance is facilitated; the attitudes held by the Keralite parents and their children towards their first language (L1), the initiatives taken by parents, religious and cultural organizations; and the role of educational institutions in promoting language maintenance. Data for this study have been gathered from semi-structured interviews and participant observation of Keralites who have lived in Oman for more than ten years. Analysis of the data indicates that while parents value their mother tongue as their first language and take various measures to maintain it, second-generation children are not keenly attached to L1. Instead, their first language oracy is strikingly marked with code-switching and code shifting, and their writing skills in L1 are diminishing. Refuting the previous findings, the present study reveals that language shift is a temporary phenomenon, and it does not take place at the cost of L1. On the contrary, various factors contribute to the maintenance of their heritage language. Also, the migrant Keralites, as a result of their living abroad, acquire two or three more new languages: English, Hindi, and Arabic depending on their study and work domains, thereby making them a multilingual society. Language shift can gradually result in linguicide, which can have various effects such as alienation from and the loss of culture and cultural values. It is expected that this study will unveil if there is a language shift of a severe nature among the Keratitis in Oman.
