Equilibrium moisture content: Use of intergranular relative air humidity sensors in silos
Authors: Ferreira Junior Weder N. , Resende Osvaldo , Sousa Kelly A. de , Costa Lilian M. , Quirino José R.
Published: June 2024

ABSTRACT Grains are hygroscopic materials and, during storage, they are subject to exchanging moisture with the environment according to temperature and relative air humidity, making it important to monitor these factors. Digital temperature and relative air humidity sensors appear as an alternative for monitoring the moisture of grain mass inside silos; they are simple to install and use. Digital sensors present outstanding precision in temperature measurements. The objective in this study was to assess the efficiency and applicability of intergranular relative air humidity sensors linked to digital temperature sensors in the thermometry system of silos storing soybeans. Two samples of soybeans were analyzed in the upper, middle and lower thirds of the silo, for grain mass temperature, intergranular relative air humidity, estimated equilibrium moisture content according to collected data, and moisture content of the sampled grains. Moisture contents obtained from sensor measurements using the hygroscopic equilibrium equation and determined using the oven method were compared. The equilibrium moisture content estimated by the data provided by the sensors did not differ by the Tukey test (p ≤ 0.05) from the moisture content determined by the oven method. Digital temperature and relative air humidity sensors have proven to be efficient, as they contribute to estimating the equilibrium moisture content with satisfactory precision.

ABSTRACT Polymerase chain reaction (PCR) with complementary primers to the polyhedrin gene region was used to diagnose B. mori nucleopolyhedrovirus (BmNPV) infection. Experimental infections were performed for the standardization of the PCR assay. The PCR products were sequenced and specificity of the amplification was confirmed by comparison with BmNPV nucleotide sequences available in the GenBank. An identity level of about 99% was observed for those PCR products when compared to the known BmNPV sequences. The viral gene fragment amplification protocol proposed here is useful for early diagnosis of nucleopolyhedrosis in whole larvae, hemolymph, and infected eggs or in asymptomatic insects. Moreover, the standardized PCR can be used as a tool for surveillance and control of nucleopolyhedrosis in silkworm rearing.

THE CORPORATE BOND MARKET AND ALTERNATIVE DEBT SOURCES IN BRAZIL: A COMPARATIVE ANALYSIS (2004-2014)
Authors: Carvalho Paula Silva de
Published: June 2024

ABSTRACT: This study investigates the relation between the corporate bond market and the main debt financing alternatives available to firms in Brazil from 2004 to 2014. In this period, three main sources of debt financing were available: loans from commercial banks, loans from the National Development Bank, and the issuance of international bonds. We analyze the characteristics of each alternative, as well as their advantages and disadvantages in relation to corporate bond issuance, considering three main aspects: i) total cost, which includes the interest rate, taxes and fixed costs; ii) maturity; and iii) contracting speed. The results corroborate the initial hypothesis that, although the alternative debt sources competed with corporate bonds, there was also a complementary relation among them.

Authors: Bento Amilton , Silva Narbal , Pais Leonor , Santos Nuno Rebelo dos
Published: June 2024

Resumo: A proatividade e o capital psicológico (PsyCap) são construtos associados às virtudes psicológicas, recursos despertados por fatores individuais e organizacionais, que podem maximizar resultados. Este estudo visou investigar qualitativamente os determinantes e aspectos que podem estimular o PsyCap e a proatividade, a partir da perspectiva de trabalhadores de duas empresas brasileiras. A pesquisa foi realizada por meio de entrevistas semiestruturadas com uma amostra de 26 funcionários. Os resultados revelaram determinantes comuns para a proatividade e o PsyCap, dentre eles a aprendizagem formal e informal, o feedback, a felicidade, a persistência, a curiosidade, os desafios e a estratégia. Foram observados alguns consequentes positivos, como euforia, alegria, realização, entusiasmo, engajamento e gratidão. Notou-se também que a ausência de proatividade e níveis baixos de PsyCap podem desencadear reações negativas, como indignação, tristeza, procrastinação, paralisação, desequilíbrio e frustração. Esses resultados sugerem que intervenções focadas no desenvolvimento da proatividade e do PsyCap podem ser essenciais para potencializar o bem-estar individual e resultados positivos nas organizações.

Diferenças e Semelhanças Artísticas entre o Classicismo, o Romantismo e Walden Two
Authors: Vitti Gabriel Rodrigues , Laurenti Carolina
Published: June 2024

Resumo: O interesse de B. F. Skinner pela arte pode ser observado em diferentes publicações, com destaque para o livro Walden two (1948). Nele, Skinner considera as produções artísticas fundamentais para o estabelecimento de um ambiente social igualitário e feliz, mencionando, por consequência, uma pluralidade de obras de arte. Dada a relevância teórico-científica do livro, bem como sua diversidade artística, este artigo buscou compreender a arte descrita em Walden two com base nas vertentes artísticas tradicionais do classicismo e do romantismo. Trechos do livro que mencionavam palavras-chave associadas à arte foram compilados em tabelas e analisados de acordo com atributos clássicos e românticos, descritos por textos especializados. Foram identificadas seis principais modalidades artísticas na ficção skinneriana (literatura, teatro, música, artes plásticas, arquitetura e moda), que apresentam similaridades com o racionalismo clássico e o sentimentalismo romântico, bem como outras características que as diferenciam dessas vertentes. Conclui-se, assim, que a arte de Walden two está situada em um pluralismo artístico, que também indica a possibilidade de o comportamentalismo radical ser interpretado como uma filosofia da arte.

Authors: Silva Fellype Ribeiro da , Felipe Dara Andrade
Published: June 2024

Resumo: Hegemonicamente exercida nos centros urbanos, o processo de interiorização das políticas sociais reconfigurou as práticas da psicologia no século XXI. Atualmente, 70% dos locais em que os psicólogos atuam no Brasil são marcados por características rurais e têm a presença de povos e comunidades tradicionais. Assim, é indispensável considerar as peculiaridades da vida no campo, de modo a visualizar as diversas dimensões que exercem influência sobre a saúde desse povo. No presente trabalho, destaca-se o conceito de território como capaz de permitir uma análise sobre as necessidades de saúde e as práticas de cuidado a serem desenvolvidas junto às populações do campo. Nesse sentido, tem-se como objetivo relatar a experiência de atuação de um psicólogo residente na Residência Multiprofissional em Saúde da Família com Ênfase nas Populações do Campo em três comunidades quilombolas do município de Garanhuns-PE. Para isso, foram sistematizados os registros do diagnóstico de saúde, realizado pela equipe de residentes, e o diário de campo do autor do relato, referente ao primeiro ano da residência. O material foi analisado de acordo com o método de Análise de Conteúdo e organizado em três categorias: territorialização e diagnóstico; estratégias de cuidado individual e coletivas; acesso e limitações da rede de saúde e atuação multiprofissional e interprofissional. Confirmou-se que a experiência na residência contribui significativamente para a formação do psicólogo no âmbito do SUS e da Atenção Primária, favorecendo a construção de práticas não-hegemônicas e contribuindo para atuação interdisciplinar e intersetorial, particularmente no que se refere à saúde da população do campo.

Resumo: Com a emergência da pandemia de Covid-19, as(os) psicólogas(os) passaram a oferecer atendimento online para pacientes que até então eram atendidos de forma presencial. Na maior parte dos casos, essa mudança se deu de forma improvisada e sem capacitação prévia. Nesse contexto, este estudo, de caráter descritivo-exploratório, quanti-qualitativo e com delineamento transversal, buscou compreender a experiência das(os) psicólogas(os) na transição das intervenções da modalidade presencial para o atendimento remoto durante a pandemia de Covid-19 no Brasil, identificando dificuldades e lacunas percebidas nas orientações disponibilizadas pelo Conselho Federal de Psicologia. Participaram da pesquisa 385 psicólogas(os). Utilizou-se um questionário online para a coleta dos dados, distribuído por meio de uma plataforma digital entre maio e novembro de 2020. O estudo também foi divulgado em grupos da categoria profissional da psicologia em diversas redes sociais. Os dados quantitativos foram analisados por meio de análise estatística descritiva, e as respostas para as questões abertas por meio de análise temática reflexiva. Os achados foram organizados em três categorias temáticas: (a) lacunas percebidas nas orientações quanto à escolha da plataforma digital; (b) lacunas quanto ao preenchimento do cadastro no site E-Psi ; e (c) falta de treinamento adequado para realizar a transição para o formato online. Entre os principais resultados, destacaram-se a insegurança gerada pela falta de preparo prévio das(os) profissionais e a resistência de alguns clientes a aceitar a transposição dos atendimentos do modelo presencial para o online. Espera-se que o mapeamento das principais dificuldades enfrentadas pela categoria contribua para qualificar o debate sobre a efetividade das orientações disponibilizadas para as(os) psicólogas(os).

Published: June 2024

ABSTRACT Background: Non-invasive markers have been developed to assess the presence and severity of liver abnormalities related to non-alcoholic fatty liver disease (NAFLD). Objective: To analyze the diagnostic accuracy of non-invasive NAFLD markers (NAFLD liver fat score [NLFS], non-invasive non-alcoholic steatohepatitis detection score [NI-NASH-DS] and fibrosis score based on four variables [FIB-4]) in individuals with obesity undergoing bariatric surgery. Methods: A descriptive retrospective cross-sectional study was carried out enrolling 91 individuals who underwent bariatric surgery at a tertiary-level public university hospital. Non-invasive NAFLD markers were calculated using laboratory tests, clinical and anthropometric variables and diagnostic accuracy tests were calculated comparing them in relation to the gold-standard test for this analysis (histopathological evaluation). Results: A total of 85.7% of the participants were female and mean age was 39.1±9.8 years. The average body mass index was 38.4±3.6 kg/m2. At histopathological examination, 84 (92.3%) patients presented with steatosis, 82 (90.1%) with some type of fibrosis; 21 (23.1%) patients were diagnosed with NASH according to the NAFLD activity score criteria. The overall accuracy of NLFS score was 58.2% for general hepatic steatosis and 61.5% for moderate to severe steatosis. The overall accuracy of FIB-4 was 95.4% for advanced fibrosis. NI-NASH-DS had a 74.7% overall accuracy for NASH. Conclusion: In a population of individuals with obesity, the FIB-4 score had high overall accuracy in assessing the presence of advanced liver fibrosis, whereas the NFLS and NI-NASH-DS had moderate accuracies for the assessment of steatosis and NASH, respectively.
Assessment of thermal stress risk in mass concrete elements: use of expedited diagrams

Published: June 2024

Abstract Large structural elements have been commonly observed in increasingly tall buildings, employing mass concrete elements in their foundations. In these elements, the internal heat generated by the cement hydration can be decisive for the occurrence of pathological manifestations arising from the balance of stresses and also by delayed ettringite formation. This article presents a practical and expedited method, through diagrams, for a preliminary assessment of the thermo-tensional risk involved in the concreting of large-scale elements. For the development of thermal risk diagrams, the commercial software TSA-2D was used, where 64 numerical computational simulations were conducted, varying the parameters with the greatest influence on the concrete thermal phenomenon (minimum dimension of the structural element, cement content per cubic meter, cement hydration heat, concrete placement temperature, and ambient temperature). The result of this methodology, when compared to computational simulations and field monitoring in a specific case study, showed a good correlation, with the potential for application and reproducibility, considering the natural limitations of an expeditious practice that needs to be evaluated on a case-by-case basis, but which provide an important guideline in the early decision-making on-site. Furthermore, the maximum absolute error between the results of computational simulation and field monitoring was only 1.6%.
Analysis of wood fly ash as a sustainable alternative to cement replacement in concrete
Authors: Ewert Harold , Guiñez Felipe , Escribano Daniella , Pradena-Miquel Mauricio
Published: June 2024

Supplementary cementitious materials (SCMs) can contribute to reducing the carbon dioxide footprint of concrete. One of these SCMs is biomass fly ash (BFA), which is waste from wood production. Although different researchers have used BFA as SCM, it is fundamental to know the behaviour of concrete with local materials (including available BFAs) to reduce the environmental impact of transportation. In particular, the Biobío region produces 57% of Chilean wood, concentrated in Eucalyptus globulus and Pinus radiata production. This paper describes the behaviour of concrete mixtures with replacements of eucalyptus BFA (BFAE) or pine BFA (BFAP) at 0, 10 and 20% by weight of cement. Workability, compressive and flexural tests were performed, and the specimens were examined using scanning electron microscopy as well. The results showed that BFAE reduced the slump of fresh concrete and BFAP increased it in all cases due to their morphology. An increase in resistance at later ages was evident due to an increase in pozzolanic activity and an improvement in BFA morphology. The results indicate that BFAE and BFAP are suitable for replacing at least 10% of cement, because those mixes present similar, and even higher, compressive and flexural strengths than the control mix.
Investigating the role of flight phase and task difficulty on low-time pilot performance, gaze dynamics and subjective situation awareness during simulated flight
Authors: Ayala Naila , Kearns Suzanne , Irving Elizabeth , Cao Shi , Niechwiej-Szwedo Ewa
Published: June 2024

Gaze behaviour has been used as a proxy for information processing capabilities that underlie complex skill performance in real-world domains such as aviation. These processes are highly influenced by task requirements, expertise and can provide insight into situation awareness (SA). Little research has been done to examine the extent to which gaze behaviour, task performance and SA are impacted by various task manipulations within the confines of early-stage skill development. Accordingly, the current study aimed to understand the impact of task difficulty on landing performance, gaze behaviour and SA across different phases of flight. Twenty-four low-time (<300 hours) pilots completed simulated landing scenarios under visual flight rules conditions. Traditional gaze metrics, entropy-based metrics, and blink rate provided meaningful insight about the extent to which information processing is modulated by flight phase and task difficulty. The results also suggested that gaze behavior changes compensated for increased task demands and minimized the impact on task performance. Dynamic gaze analyses were shown to be a robust measure of task difficulty and pilot flight hours. Recommendations for the effective implementation of gaze behaviour metrics and their utility in examining information processing changes are discussed.
Discapacidad cognitiva en la educación superior: crítica, contexto y reflexión
Authors:   Universidad Cooperativa de Colombia, Jaimes José Jairo , Acacio Quintero Ronald
Published: June 2024

La discapacidad cognitiva o intelectual (DC/DI) según la Asociación Americana de Discapacidad Intelectual y Discapacidades del Desarrollo (AAIDD) es dinámica y funcional, es decir, que el desempeño de un sujeto con esta discapacidad se puede reflejar en su entorno y no necesariamente desde sus rasgos clínicos, considerando que este puede desarrollar habilidades que le permitan adaptarse al medio. Se entiende por esto que una persona con DC/DI tiene la posibilidad de enfrentarse a diferentes campos de acción en su cotidianidad (laboral, educativa e interpersonal) y, en su interacción con estos, desarrollar nuevas habilidades y competencias que le ayuden a su propio crecimiento personal, lo cual se logra gracias a la inclusión que permite desde diferentes contextos brindarles oportunidades y prevenir la exclusión; es decir, la segregación ante las características de su trastorno. Por lo tanto, desde el desarrollo profesional docente, es importante reflexionar en cuanto a la formación integral en los procesos de inclusión de personas con DC/DI, con el fin de reconocer la diversidad intercultural del alumnado y, en aras de una crítica constructiva, lograr una educación de calidad basada en contextos inclusivos, donde se reconozca la diferencia y la diversidad como parte natural del ser humano.

The paper examines the issues of synthesis of mathematical models of the main types of distributed passive interference ‒ the earth's surface and meteorological formations. A mathematical apparatus has been developed that makes it possible to determine the sampling step of the distribution of reflective properties over the earth's surface, as well as the requirements for the spectra of Doppler fluctuations of reflections from atmospheric heterogeinity, at which specified levels of errors in simulating echo signals are ensured. Generalized algorithms for synthesizing models of these radar objects are presented. The correctness of the results obtained was confirmed by digital modeling. The monograph may be of interest to a wide range of scientific, engineering and technical workers specializing in the field of radar, radar measurements, simulation and semi-natural modeling. It can be of benefit to teachers, graduate students and senior students of relevant specialties.
EFFECT OF ULTRASONIC PROCESSING ON THE PROPERTIES OF ULTRAFINE-GRAINED BRASS

Published: June 2024

This article establishes the relationship between the parameters of an ultrasonic action on the microstructure and the complex properties of ultrafine-grained brass. Ultrasonic action on brass after radial-shear rolling at certain amplitudes of mechanical stresses helps to relax the nonequilibrium structure of grain boundaries and relieve internal stresses. In this case, the relaxation effect of the structure depends on the amplitude of the ultrasound. It has been shown for the first time that ultrasonic processing is an effective way to relax the structure of highly deformed materials, which leads to an increase in the proportion of large-angle grain boundaries and triple grain joints, without leading to a significant grain growth.
DISPERSION OF AQUEOUS Y2O3 NANO-SUSPENSION AND FABRICATION OF TRANSPARENT CERAMICS BY COLLOIDAL PROCESSING
Authors: He Jiao , Zhang Xin , Lian Jingbao , Zhang Xue , Lei Mingxia
Published: June 2024

In the present study, transparent Y2O3 ceramics were successfully fabricated via colloidal processing, employing polyethylenimine (PEI) as an effective dispersant. The effect of PEI on nanosized Y2O3 suspensions was characterized by zeta-potential, adsorption behavior, rheological properties, and sedimentation test. The addition of PEI shifted the IEP of the Y2O3 powder towards a more alkaline pH range, and the adsorption of PEI on the Y2O3 surfaces gradually increased with the amount of PEI until reaching the saturation adsorption at 1.5 w/%. The PEI amount of 1.5 w/% was superior for the preparation of Y2O3 suspension as a result of a lower viscosity or sedimentation behavior. The viscosity of the suspension depended on the solids loading, increasing with the amount of powder. The optimal rheological behavior was achieved with 29 /% Y2O3 in the suspension, enabling the centrifugal slip casting of complex-shaped green bodies with a packing density of 43 %. Including an additional CIP treatment boosted the packing density of the green compacts, achieving above 50 %. Vacuum sintering the compacts at 1700 °C for 5 h yielded high-density ceramics exhibiting an in-line transmittance of approximately 73 % at a wavelength of 1100 nm.

Published: June 2024

Steroid hormones are important modulators of many physiological processes, and measurements of steroids in blood, saliva, and urine matrices are widely used to assess endocrine pathologies and stress. However, these matrices cannot be used to retrospectively assess early-life stress and developmental endocrine pathologies, because they do not integrate steroid levels over the long term. A novel biological matrix in which to measure steroids is primary teeth (or “baby teeth”). Primary teeth develop early in life and accumulate various endogenous molecules during their gradual formation. Here, we developed and validated the first assay to measure steroids in human primary teeth using liquid chromatography-tandem spectrometry (LC-MS/MS). Our assay is highly sensitive, specific, accurate, and precise. It allows for the simultaneous quantification of 17 steroids in primary teeth (16 of which have not been examined previously in primary teeth). Overall, steroid levels in primary teeth were relatively low, and 8 steroids were quantifiable. Levels of dehydroepiandrosterone, cortisol, and progesterone were the highest of the 17 steroids examined. Next, we used this assay to perform steroid profiling in primary teeth from males and females. The same 8 steroids were quantifiable, and no sex differences were found. Levels of androgens (androstenedione and testosterone) were positively correlated, and levels of glucocorticoids (cortisol, cortisone, corticosterone, 11- dehydrocorticosterone) were also positively correlated. These data demonstrate that multiple steroids can be quantified by LC-MS/MS in human primary teeth, and this method potentially provides a powerful new way to retrospectively assess early-life stress and developmental endocrine pathologies.

Care Coordination of the Pediatric Intensive Care Unit
Authors:   , Stirk Katheryn , Poyss Alicemarie R.
Published: June 2024

Lack of standardization of multidisciplinary rounds can cause ambiguous threats to the care provided to a patient, especially a critically ill pediatric patient that care needs to be individualized and complex. Implementation of a rounding checklist is one tool that can improve care coordination and communication between the care team taking care of the pediatric patient. This quality improvement project collects pre and post implementation data to analyze the effectiveness of a standardized checklist for multidisciplinary rounds in a Pediatric ICU. The metrics followed were patient safety reports and staff survey results. The focus group conducted a PDSA halfway through the implementation phase. The results showed that implementing a rounding checklist did not provide the desired outcome. Even though the results were not in favor of the projected outcome, the rounding checklist was a good starting point in standardizing Multidisciplinary rounds and bringing awareness to all stakeholders of the communication gap between the care team and ignite discussions for further improvements. Implementing a standardized way of conducting Multidisciplinary rounds in the Pediatric ICU did not decrease the risk of adverse patient safety events or increase staff's perception of care coordination. Further discussions and modifications need to be conducted moving forward. Keywords: Pediatric ICU, Multidisciplinary Rounds, Rounding Checklist
Death of Others and Social Mourning Due to National Disaster: Based on Judith Butler's Philosophy
Authors:   Research Institute For Life And Culture Sogang University, Moon Sung-Yun
Published: June 2024

Korean society has experienced a somber social atmosphere in the last five years due to the Corona19 pandemic and the Itaewon disaster. This situation can be classified as a national disaster that affects the mental and mental state of the whole country. The national disaster, like any other ordeal, leaves us with a scar of pain. The national disaster leaves a sense of social shock, hurt, and loss and requires a corresponding act of mourning.
This paper philosophically considers death during the national disaster and examines the direction of social mourning to heal this wound. The study focused on the thoughts of American ethical philosopher Judith Butler. According to Butler, the national disaster reveals the vulnerability of human society, and when we face this vulnerability and participate in mourning, social integration can be overcome. So, the direction of social mourning that Butler explains is ‘the attitude of responsibility, not retribution, the vulnerability and precarity of life revealed as the true form of a national disaster,' and ‘mourning that unites society.’
A practical philosophical plan was suggested for applying this to Korean society. The first is what Butler calls willless sensitivity, the second is self-thinking and phenomenological parentheses, and the third is social integrated growth. This study is significant because it laid the foundation for developing more specific future methodologies and programs for social mourning.
Artificial Intelligence Item Analysis Tool for Educational Assessment: Case of Large-Scale Competitive Exams
Authors:   Regional Center of Education & Training Professions, Institutions for Higher Executive Training, Tangier, Morocco, Hrich Najoua
Published: June 2024

With the increased number of competitive examinees, adopting Multiple Choice Tests (MCTs) in most examinations has significantly shaped the assessment methodology. However, the success of this method depends on the quality of the items. Thus, selecting relevant items, balanced for difficulty and discrimination power, is crucial to guarantee the assessments’ validity and reliability. In this regard, integrating Artificial Intelligence (AI) provides promising prospects for further enhancing the item analysis and selection process. Therefore, this research aims to build a Machine- Learning (ML) model that discerns and selects items based on their difficulty and discrimination. This study employs the Artificial Neural Networks (ANN) method through binary classification models for item classification. The study’s experimental results demonstrate the proposed model’s efficacy, showcasing superior performance with an accuracy rate of 96% for item selection.
A Study on the Average Number of LLL-based Using Statistical Learning
Authors: Song Kyunghwan , Seo Yun Am
Published: June 2024

Lattice-based Cryptography is known as one of the key technologies in modern cryptography. This encryption scheme has the basis vectors from the lattice as the public key and a short-length vector in the lattice consisting of an integer combination of the basis vectors as the secret key. To break this encryption, we need to solve the Shortest Vector Problem (SVP), known as NP-hard. Therefore, instead of finding the shortest vector, LLL algorithm is often used to find a vector of sufficiently short length to break the encryption. The LLL algorithm is a well-known method for breaking this encryption, but there is still no clear answer to the question of how many times the LLL algorithm needs to be used to obtain the desired level of secret key, the average number of the (, )-LLL bases in dimension n is a tool to measure the probability that the LLL algorithm solves the SVP. We can expect that this number indicates how many times the appropriate algorithm should run. There is a formula for this, but it contains some functions that take a long time to compute. We apply linear regression to the formula of the average number of the (, )-LLL bases in dimension n, and therefore we obtain some formulas to approximate the average number of the (, )-LLL is based on dimension n, which contains simple functions. When the dimensions are high, our model is much better regarding the computation time.

Analizy w pracy prowadzone są na przykładzie systemu roweru wojewódzkiego – Rowerowe Łódzkie i dotyczą jego wykorzystania w dojazdach do przystanków kolejowych Łódzkiej Kolei Aglomeracyjnej (ŁKA). Rozdział prezentuje wyniki badania ankietowego zrealizowanego na próbie 116 respondentów będących użytkownikami Łódzkiej Kolei Aglomeracyjnej. Z przeprowadzonych analiz wynika, że mimo iż respondenci pozytywie oceniają system pod względem jego wpływu na dostępność do ŁKA, w niewielkim stopniu z niego korzystają. Rozmieszczenie stacji rowerowych wskazuje, że poprawa tej dostępności dotyczy głównie większych gmin.

Rozdział dotyczy rozwoju elektromobilności w Polsce. Opisuje on istotę elektromobilności, uwarunkowania jej rozwoju, aspekty ekologiczne pojazdów elektrycznych i ograniczenia ich efektu środowiskowego. Dodatkowo, został przeanalizowany popyt na tego typu samochody w Polsce. Głównym celem badania, którego wyniki prezentuje rozdział, była ocena postrzegania elektromobilności wśród Polaków oraz identyfikacja intencji zakupu samochodu elektrycznego. Zastosowano ilościową metodę badawczą – technikę ankiety, którą zrealizowano na próbie 141 osób. Wyniki badania wskazują, że respondenci w większości (66%) postrzegają samochody elektryczne za ekologiczne, ale są świadomi ich ograniczeń w osiąganiu korzyści środowiskowych. Wśród respondentów przeważają użytkownicy pojazdów spalinowych, którzy najczęściej negatywnie oceniają samochody elektryczne pod względem kosztów zakupu i eksploatacji, niewystarczającego zasięgu, któremu towarzyszy nierozwinięta w odpowiednim stopniu infrastruktura ładowania pojazdów. Właściciele samochodów elektrycznych z kolei podkreślają związane z nimi korzyści finansowe w postaci niskich kosztów eksploatacji, możliwości bezpłatnego parkowania w płatnych strefach parkingowych a także korzyści środowiskowe (niska emisja hałasu i CO2). Ponad 37% ankietowanych wyraziło chęć zakupu samochodu elektrycznego w przyszłości.

Published: June 2024

Об'єктом досліджень є процеси обчислювальної реалізації алгоритмів захисту інформації на основі криптографії з відкритим ключем, базовою операцією яких є модулярне експоненціювання. В статті здійснено огляд існуючих методівобчислення модулярної експоненти для механізмів захисту інформації. Показано, що в сучасних умовах їх суттєвий недолік полягає в низькій швидкодії, зумовленій складністю обчислювальної реалізації експоненціювання над числами великої розрядності. Мета роботи полягає в прискоренні обчислювальної реалізації модулярного множення чисел, довжина яких значно перевищує розрядність процесора – базової операції сучасних криптографічних алгоритмів захисту даних з відкритим ключем. Для досягнення поставленої мети запропоновано метод, в якому прискоренняобчислення модулярного множення досягається за рахунок за рахунок суміщенням множень секцій чисел з симетричними індексами, а також чередування циклів додавання секційних добутків з однаковою вагою і груповою редукцією Монтгомері.

A series of twenty two novel piperazine derivatives were screened for their antimicrobial activities by disc diffusion method and micro dilution method against the ATCC strains of certain selected Gram- positive (MRSA, Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli, Klebsiella pneumoniae, Citrobacter, Shigella flexineri, Pseudomonas aeruginosa) with the standard drugs amongst the synthesized novel compounds RL-308, RL-327and RL-328 showed potent anti bactericidal activities. Hence, they were subjected to higher assays with different concentrations and were compared to the respective standard drugs. Then Minimum inhibitory concentration (MIC) assay, Minimum bactericidal concentration (MBC) assay were performed to those three compounds. Minimum concentration of RL-308 was analyzed by using MIC assay which displayed a potent results against Shigella flexineri, S.aureus, MRSA & Shigella dysentriae at the concentration of 2ug, 4ug, 16ug &128 ug concentration. It proved to be very effective against Shigella flexineri at the concentration of 2ug. Where in RL-328 showed MIC at the concentration of 128ug. The MBC of the compound RL-308 was estimated to be 4ug, 8ug, 32ug against the same pathogenic bacterial strains. Hence, the piperazine compound RL-308 proved to be very effective antibacterial activity against human pathogens and can be used as an effective antibacterial agent to cure diseases caused by Shigella flexineri, S. aureus, Methicillin resistant S. aureus & Shigella dysentriae.
