Published: May 2023

The Papaya Mealybug, Paracoccus marginatus Williams and Granara de Willink, is an invasive species. The abundance of the papaya mealy bug and its damage to seedlings were investigated in the field at three agro-ecological zones: which includes Akure (Rainforest), Ogbomoso (Guinea savannah), Ibadan (Derived savannah) in the 2016 growing seasons. At each site, 10 healthy mother plants with fruit (>17cm GBH) were randomly selected from which five infested and non-infested leaves (fifth to the 13th leaf from the top) were randomly selected. Number of infesting larvae were counted manually. Infestation, typified by woolly presence of the larvae on the leaves was 80.08% on the leaves and 75.58.6% on the fruits. The most susceptible papaya was recorded for Ogbomoso in March. This was done to determine the combined effects of time of the year (period) and geographical location (Agroecology) on populations and infestations of adult and immature P. marginatus on fruits and leaves of Pawpaw, and it was not significantly different (p>0.05) from the other levels of infestation at the other locations in the same month of March. The highest population of P. marginatus on Pawpaw leaves (60.33) and fruits (59.83%) was recorded for Akure in March. Results showed that there was general reduction in mean number of healthy leaves of papaya seedlings as the age of the seedlings increased. It could be concluded that P. marginatus were able to establish colonies on papaya seedlings, it is only in rare cases on a few susceptible genotypes, that mealybugs colonize plants during vegetative stage

Integrating Knowledge-based and Data-driven Approaches for TTC Assessment in Power Systems with High Renewable Penetration
Authors: Zhu Yuhong , Zhou Yongzhi , Wei Wei
Published: May 2023

Assessment of total transfer capability (TTC) is vital for determining the permissible power transfer between two areas of an interconnected power system. In the context of heightened volatility and time-variability in power system operating states after integrating high proportions of renewable energy, data-driven inferential assessment methods emerge as promising alternatives, offering faster assessment capabilities compared to knowledge-based iterative methods. However, data-driven methods typically struggle to establish reliable connections between assessment outcomes and security standards, hindering the guarantee of conservatism. A hybrid algorithm, combining knowledge-based and data-driven techniques, is proposed to accurately and efficiently assess TTC while strictly complying with pre-established security and stability constraints. Data-driven inference accelerates knowledge-based iterative processes by rapidly identifying reasonable initial values and providing adaptive step sizes, while knowledge-based analysis guides data-driven methods through offering stability margin information. This mechanism leverages the speed of data-driven methods while maintaining conservatism through knowledge-based approaches. The effectiveness of the proposed method is verified on benchmarks, including the IEEE 30-bus system and a real-world power system, which also exhibits conservatism and robustness in the face of increasing renewable energy penetration.

Distributing Data with Zero Migration
Authors: Yue Jonathan
Published: May 2023

ZeroMove hashing is a novel data distribution technique for distributed systems that offers several key benefits. In contrast to the consistent hashing algorithm, which requires data migration when scaling the system, ZeroMove hashing enables the addition of clusters of nodes on demand without the need to move data between nodes. A cluster is located using an encoded unique identifier, while a node is identified with a hash function within a cluster. This approach ensures that data remains in the node where it is hashed, thereby increasing availability and improving system performance. Furthermore, the ZeroMove hashing technique can significantly reduce facility and administrative expenses, making it an excellent option for largescale distributed systems. Our tests on consistent hashing and ZeroMove hashing have shown that scaling from one node to six nodes with 480,000 data records took 6100 seconds in a system based on consistent hashing. In contrast, it took only 1.2 seconds for ZeroMove hashing to achieve similar scaling under the same settings. With consistent hashing, the time taken and amount of data moved increase proportionally with the amount of data stored in the system. However, with ZeroMove hashing, these values does not increase in proportion to the amount of data being stored. This is because ZeroMove hashing only involves the exchange of small amount of metadata between nodes during scaling processes.

A Generic Performance Model for Deep Learning in a Distributed Environment

Published: May 2023

Performance modelling of a deep learning application is essential to improve and quantify the efficiency of the model framework. However, existing performance models are mostly case-specific, with limited capability for the new deep learning frameworks/applications. In this paper, we propose a generic performance model of an application in a distributed environment with a generic expression of the application execution time that considers the influence of both intrinsic factors/operations (e.g. algorithmic parameters/internal operations) and extrinsic scaling factors (e.g. the number of processors, data chunks and batch size). We formulate it as a global optimization problem and solve it using regularization on a cost function and differential evolution algorithm to find the best-fit values of the constants in the generic expression to match the experimentally determined computation time. We have evaluated the proposed model on three deep learning frameworks (i.e., TensorFlow, MXnet, and ytorch). The experimental results show that the proposed model can provide accurate performance predictions and interpretability. In addition, the proposed work can be applied to any distributed deep neural network without instrumenting the code and provides insight into the factors affecting performance and scalability.
Protocols for healing radiation damaged single-photon detectors suitable for space environment
Authors: Krynski Joanna , Sultana Nigar , Lee Youn Seok , Makarov Vadim , Jennewein Thomas
Published: May 2023

Single-photon avalanche detectors (SPADs) are well-suited for satellite-based quantum communication because of their advantageous operating characteristics as well as their relatively straightforward and robust integration into satellite payloads. However, space-borne SPADs will encounter damage from space radiation, which usually manifests itself in the form of elevated dark counts. Methods for mitigating this radiation damage have been previously explored, such as thermal and optical (laser) annealing. Here we investigate in a lab, using a CubeSat payload, laser annealing protocols in terms of annealing laser power and annealing duration, for their possible later use in orbit. Four Si SPADs (Excelitas SLiK) irradiated to an equivalent of 10 years in low Earth orbit exhibit very high dark count rates (>300 kcps at -22 C operating temperature) and significant saturation effects. We show that annealing them with optical power between 1 and 2 W yields reduction in dark count rate by a factor of up to 48, as well as regaining SPAD sensitivity to a very faint optical signal (on the order of single photon) and alleviation of saturation effects. Our results suggest that an annealing duration as short as 10 seconds can reduce dark counts, which can be beneficial for power-limited small-satellite quantum communication missions. Overall, annealing power appears to be more critical than annealing duration and number of annealing exposures.

Published: May 2023

Este artigo discute o movimento do (re)planejamento das atividades realizadas no Estágio Supervisionado (ES), no curso de Licenciatura em Química numa Instituição Pública Federal, da perspectiva do ensino presencial para o remoto. Especificamente, entender o que foi possível permanecer do planejamento anterior para o que foi realmente viabilizado. Apresentam-se em três movimentos de discussão. Inicialmente, na fundamentação teórica, onde se situa a formação de professores, planejamento e o ES num movimento disruptivo. Na sequência, visualiza-se o percurso do planejamento no ES num movimento do ensino presencial ao remoto e as aprendizagens evidenciadas, finalizando com algumas perspectivas e desafios no planejamento do ES enquanto considerações possíveis. As perspectivas se complementam com os desafios no replanejamento do ES, como demonstram os indícios das fragilidades do ensino presencial. Isto, simultaneamente em que se indicou o caminho para um novo cenário à formação dos professores que promoveram a disrupção, a desconstrução de algumas concepções de ensino, e a avaliação para a (e na) aprendizagem no contexto de um ambiente virtual. Neste processo, de modo geral, obteve-se mais ganhos do que perdas. Enquanto as mudanças obrigatórias, no fazer pedagógico, acarretaram novos saberes docentes experienciados no, e para o, ensino remoto, que se perpetuam agora, no ensino presencial, através da utilização das TIC.

Como estudantes de um curso de licenciatura em química na rede federal de educação profissional e tecnológica concebem a prática docente no estágio supervisionado?
Authors: Vasconcelos Rosa Maria Oliveira Teixeira de , Fireman Elton Casado
Published: May 2023

Objetivou-se com esse estudo apresentar um recorte dos resultados da pesquisa de doutorado concluída em 2021, que teve como um dos objetivos mapear as concepções de prática expressas nas falas dos sujeitos discentes acerca do estágio supervisionado. O campo da pesquisa configurou-se num curso de licenciatura em química da rede federal de educação, ciência e tecnologia de Pernambuco, na modalidade presencial. A pesquisa de natureza qualitativa lançou mão do questionário como instrumento de coleta, tendo realizado a análise dos dados com base na análise de conteúdo categorial temática. Dentre as concepções mapeadas identificamos a compreensão das práticas no estágio supervisionado como mera aplicação da teoria, utilização de métodos e técnicas numa perspectiva instrumental, embora outros resultados demonstrem contradições entre as compreensões do grupo investigado, que ora demonstram uma concepção de prática meramente pragmático, instrumental, e ora deixam escapar compreensões mais alicerçadas numa compreensão de aproximação com a realidade numa relação indissociável entre teoria e prática.

Authors: Schlemper Susana Regina De Mello , Mello Denise Maria Sousa de
Published: May 2023

O estágio supervisionado como processo formativo pode proporcionar o contexto de aprendizagem originada do trabalho colaborativo, e a pesquisa-ação participativa (PAP) pode potencializar o ensino, a aprendizagem e a alfabetização científica. Visando, atender dois objetivos, aplicação do projeto de estágio nas escolas e simultaneamente prática de ensino e regência de classe na educação básica, o estudo teve como finalidade identificar as explicações causais dadas pelos alunos sobre que é, quem faz, como se faz e onde é feita a ciência, e verificar a forma pela qual, são capazes de ir além da descrição dos fenômenos, elaborando conceitos científicos e construindo o conhecimento socialmente adquirido. A PAP envolveu 144 alunos do sétimo ano do Ensino Fundamental. A alfabetização científica foi realizada em três passos: 1.apresentação da PAP para direção/professores regentes e observação dos alunos; 2.sensibilização dos alunos; 3.discussão conceitual, roda de conversas e exposição de idéias. A partir de quatro perguntas abertas, foi analisado interpretativamente o material escrito, para contextualização e compreensão das respostas. Evidenciou-se que as experiências conceituais são resgatadas dos significados vividos socialmente, do senso comum. As aulas de ciências devem ultrapassar a ação contemplativa, trazendo para reflexão, como objetivo estratégico possibilitando pensar cientificamente o mundo.

Published: May 2023

O presente estudo tem a pretensão de aprofundar as discussões sobre a perspectiva da Abordagem Temática na formação inicial de professores de física, especialmente no contexto dos estágios supervisionados obrigatórios. Logo, o problema que permeia esta pesquisa é: quais elementos caracterizam as práticas pedagógicas balizadas pela perspectiva da Abordagem Temática no contexto dos Estágios Supervisionados em Física? Para responder o problema, foi realizada uma revisão bibliográfica nas atas do Simpósio Nacional de Ensino de Física (SNEF), com recorte temporal dos últimos dez anos, com as palavras de busca “Abordagem Temática” e “Estágio”. Nesta busca, apenas três trabalhos respondem ao problema de pesquisa. Utilizando da Análise Textual Discursiva (ATD), emergiram as seguintes categorias de análise: i) Processo de obtenção/escolha do tema; ii) A utilização da dinâmica dos Três Momentos Pedagógicos e iii) Prática educativa balizada pelos pressupostos Freireanos. Dentre os resultados alcançados, destaca-se a formação humanizadora dos futuros educadores, a partir de uma prática pedagógica dialógica e problematizadora, entendendo os estudantes como sujeitos no processo de ensino-aprendizagem.

Published: May 2023

La pandemia de COVID-19 ha supuesto un desbarajuste de los sistemas migratorios a nivel global. En este marco, y de forma particular, los efectos sobre las migraciones en América Latina son de gran magnitud en diferentes dimensiones. En este texto nos preguntamos precisamente por ello, por los efectos de la pandemia sobre las migraciones en la región latinoamericana y cómo estos dificultan la alineación nacional y regional con el Pacto Mundial para la Migración. Para ello se hace una revisión documental sistemática (literatura académica y gris) sobre los efectos de la COVID-19 en la región y sobre las acciones puestas en marcha para hacer frente a ellas. El documento indica que al menos el efecto se da sobre tres dimensiones: sobre los flujos migratorios, la gobernabilidad y los propios migrantes; y que los cambios producidos obstaculizan la consecución del acuerdo internacional en la región. Sobre esta idea, el texto finaliza postulando por una respuesta global, coordinada y de largo plazo a la nueva complejidad del sistema migratorio en América Latina.
THE MAIN STAGES OF THE EVOLUTION OF HOUSING CONSTRUCTION IN THE USSR IN THE 1920s – 1980s (PART I)

According to the Rosstat, around six seventh of the population of the Russian Federation currently keep on living in houses built from 6 to 7. Nevertheless, such issues as macro-level housing construction trends in the USSR and the structure of housing construction by source of financing have often been overlooked in the contemporary Russian economic literature. In this article, we identify five stages of the development of housing construction in the USSR during the period from 1918 to 1990. Our analysis rests upon indicators on housing completions by five-year plan and the evolution of the legistation for the housing sector. In Part I of the article, we present our review of approaches to periodisation of housing construction in the USSR from the standpoint of different research disciplines. It contains also our analysis of the first stage from 1918 to 1928 based on a broad range of sources. Part II of the article examines the results of the second stage (from 1929 to 1941) and the third stage (from 1941 to 1955), whereas Part III of the article studies the evolution of housing construction during the fourth stage (from 1956 to 1975) and the fifth stage (from 1976 to 1990). Particular attention is paid to individual housing construction, housing construction cooperatives and housing construction in rural areas as factors that influenced substantially the overall dynamics of housing construction during most of the time of the USSR’s existence.

Crimes in the sphere of economic activity are acts provided for by Chapter 22 of the Criminal Code of the Russian Federation. This category of crimes is characterized by public danger, expressed not only in encroachment on the economic interests of the state, but also on the economic interests of both legal entities and individuals. In order to minimize crimes in the sphere of economic activity, it is necessary to form effective tools, the use of which, as a result, will positively influence the development of the economy of the state as a whole and the region in particular.

BASIC PRINCIPLES OF SUSTAINABLE DEVELOPMENT
Authors:   State University for Land Management, Peoples’ Friendship University of Russia, Ragulina Yulia V.
Published: May 2023

the article shows that there are many definitions of sustainable tourism development, most of them represent the idea that there are three interdependent pillars of sustainable development: environmental, economic and social. Within the framework of sustainable development, the interdependence of the three pillars is emphasized by their potential for mutual reinforcement, but also competition with each other. Conceptual clarity, in terms of the intersection of economic, environmental and social spheres, makes it possible to determine the impact of consumption and production on the sustainable development of tourism. The participation and awareness of all stakeholders determine whether future progress towards sustainable tourism development can be achieved and approves: tourism planning, which should be considered from a rational and technical point of view (professionalism); compliance with the characteristics of each holiday destination, the needs and wishes of people who live in the area, market forces, the availability of labor resources and financing; position and place in the world market. The development of sustainable tourism in any territory cannot be just a matter of matching the product offer to tourist needs, it is very important to take into account the opinion of local residents.

Errors are common problems faced by foreign language learners during the learning process. The errors are affected by the mother tongue and other conditions. In this case, the problems occurred at the English department students at STKIP PGRI Pacitan. Therefore, the solution should be found by the lecturers by employing qualitative research-type error analysis to reveal the problems. The procedures of this research were: 1) preparation (formulating the research problem; 2) formulating the title, extensive literature survey, and preparing the research design; 3) determining sample design; 4) collecting the data, execution of the project); 5) processing (analysis of data, conclusion), report writing. Moreover, there were 40 students as the subject of this research. To get the data, the researcher took the answer sheets of essay writing of recount text to be analyzed qualitatively. In conformity with the findings, errors based on the use of past form are as the following: past simple 422 errors or 96%, past perfect 13 errors or 2,98%, past continues 1 error or 1% and past perfect continues 0 or 0%. It means that the frequent error made by the students was in using simple past tense and the absence of errors in using past perfect, past continuous, and past perfect continuous. Henceforth, the lecturers should provide more appropriate approaches and methods to solve the problematic errors.

Published: May 2023

High-rise buildings are structures that are prone to lateral loads. Every high-rise building design requires a strong structure to withstand lateral loads due to earthquake and wind loads. The use of Shear Walls can reduce the displacement that occurs due to lateral loads received because of earthquake loads and wind loads. This study aims to analyze the effect of Shear Walls on the Monde City Tower M2 Apartment building in Batam City. The method used in this study is a numerical analysis in the form of modeling a 15-story apartment building located in Batam City. The building is modeled into 2 types, namely (V1) a structure without using Shear Walls and (V2) a structure using Shear Walls according to the structural drawings. The earthquake analysis was carried out using the response spectrum method with the software ETABS v 18.1.0 for the structural analysis calculations. The results of the analysis obtained in the form of the deviation value from a structure that uses shear wall have decreased the deviation in the X direction by 12.5476 % and a decrease in the deviation in the Y direction by 68.1254 %. P-Delta in a structure that uses a shear wall is much better in structural stability than a structure that only uses a frame system.
Evans Syndrome in a Forty-Four Years Old Male Patient: A Case Report
Authors: Afriant Rudy , Fikri Avino Mulana , Kam Alexander
Published: May 2023

Background: Evans syndrome (ES) is an autoimmune disease characterized by the presence of autoimmune hemolytic anemia (AIHA) and idiopathic thrombocytopenic purpura (ITP), together with unknown causes. ES disease is the least common, diagnosed in only 0.8% - 3.7% of all patients with AIHA or ITP. This study aimed to describe Evans syndrome in a 44-year-old male patient.

Case presentation: A 44-year-old male patient was reported with complaints of weakness and fatigue, red spots, a history of bleeding gums, a history of bleeding from the nose, and a history of red urination. A routine blood examination revealed mild anemia, reticulocytosis, and thrombocytopenia, and the peripheral blood showed polychromatic erythrocytes. Other laboratory examinations revealed an increase in LDH. The results of a positive Comb’s test and antibody screening examination showed the impression of warm-type AIHA. The diagnosis of Evans syndrome in this patient was confirmed by the presence of AIHA and ITP, which co-occur and are primarily due to unknown causes.

Conclusion: ES is a rare disorder and a diagnosis of exclusion. The diagnosis of ES was established by the presence of signs and symptoms of AIHA and ITP accompanied by a positive direct antiglobulin test with no other etiology found.
Competitive Intelligence Maturity Models: Systematic Review, Unified Model and Implementation Frameworks
Authors: Madureira Luis , Popovič Aleš , Castelli Mauro
Published: May 2023

Competitive Intelligence (CI) is vital for sustaining the performance of organisations in an increasingly volatile, uncertain, complex, and ambiguous (VUCA) world. However, the impact of CI on performance is proportional to its maturity level. The article aims to review and integrate the existing literature on Competitive Intelligence Maturity Models (CIMMs) to provide a go-to framework for setting up, assessing, and developing CI. The CIMMs were sourced from scholarly databases, registers, the social web, and using backwards and forward searches. All the CIMMs respecting the characterisation criteria were included in the study. A scientific and empirically validated definition of CI guided the integration and synthesis of the fourteen selected CIMMs. The primary outcome is a proposed unified CIMM (UCIMM) covering all the CI dimensions and aspects in tandem with the respective implementation guidance frameworks. The proposed UCIMM and implementation frameworks effectuate the guidance needed to set up, assess, and develop the CI practice and theory and, ultimately, the performance of organisations.

Presently, the problem of parameter estimation is addressed for a more general nonlinear model. In this respect, the proposed nonlinear system is composed of the parallel connection of linear and nonlinear blocks. The interconnected structure of linear and nonlinear blocks systems leads to a highly nonlinear problem involving several unknown parameters and inaccessible internal signals. In this parameter estimation method, the linear and nonlinear block parameters are estimated in one stage by using simple a sine signal or multi-cosine wave.

Radioactive isotopes of rare earth elements (REE) are increasingly used in nuclear medicine for diagnostic and therapeutic purposes as they have effective nuclear physical properties. Seventeen elements of the secondary subgroup of group III of the periodic table of chemical elements of D.I. Mendeleev with atomic numbers 21, 39, 57, 58-71: scandium, yttrium, lanthanum and 14 lanthanides make up rare earth elements. Every year more and more attention is paid to the radioactive isotope of lutetium 177Lu, the most promising for use in therapeutic agents of a new generation, including for cell therapy of oncological diseases. The advantages of 177Lu are determined by its nuclear characteristics: the optimal depth of penetration into human tissues during radiotherapy of small tumors and low radiation load on healthy organs are provided due to the maximum energy of beta radiation of 496 keV, the presence of low-energy gamma radiation of 113 keV allows monitoring the treatment process, the half-life of 6.71 days makes it possible to transport drugs from 177Lu to significant distances.

The main stages of processing nickel-cadmium electrode mass of alkaline batteries, including: sulfuric acid leaching and subsequent crystallization of the main components of the system - cadmium and nickel in the form of double sulfates MSO4·(NH4)2SO4·6H2O (Tutton's salts), where M = Ni, Cd. As a result of the research, regularities in the behavior of nickel and cadmium at the stage of leaching with a solution of sulfuric acid and crystallization of double sulfates were revealed. It is shown that the separation of cadmium and nickel in the sulfuric acid solution of leaching of nickel-cadmium battery mass by crystallization of nickel and cadmium-ammonium double sulfates is achieved in three stages with the formation of crystals of the composition NiSO4·(NH4)2SO4·6H2O, in two stages of crystallization and the degree of extraction of nickel 99 %, as well as CdSO4·(NH4)2SO4·6H2O and CdSO4·(NH4)2SO4 at the third stage of crystallization. Iron remains in solution after all valuable components have been isolated.

TiO2 nanoparticles were synthesized by laser pyrolysis from TiCl4 vapor in air in the presence of ethylene as sensitizer at different working pressures (250–850 mbar) with and without further calcination at 450 °C. The obtained powders were analyzed by energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, X-ray diffractometry, and transmission electron microscopy. Also, specific surface area and photoluminescence with optical absorbance were evaluated. By varying the synthesis parameters (especially the working pressure), different TiO2 nanopowders were obtained, whose photodegradation properties were tested compared to a commercial Degussa P25 sample. Two series of samples were obtained. Series “a” includes thermally treated TiO2 nanoparticles (to remove impurities) that have different proportions of the anatase phase (41.12–90.74%) mixed with rutile and small crystallite sizes of 11–22 nm. Series “b” series represents nanoparticles with high purity, which did not require thermal treatment after synthesis (ca. 1 atom % of impurities). These nanoparticles show an increased anatase phase content (77.33–87.42%) and crystallite sizes of 23–45 nm. The TEM images showed that in both series small crystallites form spheroidal nanoparticles with dimensions of 40–80 nm, whose number increases with increasing the working pressure. The photocatalytic properties have been investigated regarding the photodegradation of ethanol vapors in Ar with 0.3% O2 using P25 powder as reference under simulated solar light. During the irradiation H2 gas production has been detected for the samples from series “b”, whereas the CO2 evolution was observed for all samples from series “a”.

Objective: To compare the number of hits of students in cervical dilation assessment in dilation simulators with and without the use of direct visual validation. Methods: This is a cross-sectional study with 40 undergraduate obstetrics students from a public university in São Paulo, who assessed cervical dilatations in blind dilatation simulators, in three stages: in the first, they estimated dilations in the simulators; in the second, they sequentially compared the findings in simulators with a direct visual validation tool using the dominant hand and then the non-dominant hand; and in the third step, they simultaneously compared the estimates found in simulators with direct visual validation with the dominant and non-dominant hands. The outcome was the success of cervical dilation in dilation simulators or not, with a p-value ≤ 0.05 considered statistically significant. Results: We analyzed 240 assessments and computed the hits of students related to cervical dilatation assessment of simulators. There was an increase in the hit rate of 47.1% with the use of direct visual validation (OR= 4.689; 95%CI: 2.601-8.452; p<0.001). Conclusion: The use of direct visual validation increases the probability of hits by students in cervical dilation assessment in dilation simulators.
