Objective Function in Combinatorial Optimization and Its Properties
Authors:   International Research and Training Center for Information Technologies and Systems of the NAS and MES of Ukraine, Tymofijeva N.K.
Published: December 2023

Introduction. Some properties of combinatorial optimization problems are described, which affect the regularity of changes in the values of the objective function regardless of the input data. It is shown that this regularity depends on the arrangement of combinatorial configurations, a certain structure of input information, the transposition of permutation elements and the symmetry of combinatorial sets (argument). In problems that are solved on permutations, and a subset of isomorphic combinatorial configurations, the class of the objective function is determined depending on their ordering and the structure of the input data. Formulation of the problem. There are works where, in combinatorial optimization, the change in the values of the objective function is investigated depending on the special structure of the input information. These studies are related to the selection of subclasses of solvable problems, and various structures are generalized for which the objective function changes in the same way. The task is to identify the parameters of problems of this class, in which the input data do not affect the pattern of changes in the values of the objective function. The proposed approach. To identify the parameters under which the input data do not affect the pattern of changes in the objective function values in combinatorial optimization, this pattern is analyzed from the arrangement of permutations, the transposition of its elements, and the structure of the input information. The change of the values of the objective function from the structure of its argument (the structure of combinatorial sets) is also investigated. Conclusion. Knowing the properties of combinatorial functions allows you to establish a change in the values of the target function depending on the transposition of the elements in the permutation, on the arrangement of combinatorial configurations. If the combinatorial set consists of one subset of isomorphic combinatorial configurations (permutations), then the set of values of the objective function follows the rules characteristic of permutations. If the set consists of subsets of isomorphic combinatorial configurations, then they can be ordered in such a way that the objective function for this ordering varies as piecewise monotonic functions regardless of the input data, and for the isomorphic subset it varies as in problems whose objective function argument is the permutation.

Published: December 2023

This article highlights the results of the first initial study of the international and domestic legal bases for the introduction of “inclusive business partnership” in Ukraine as a new organizational and legal form of systemic interaction between economic entities and civil society institutions in the process of joint economic activity with the assistance of public authorities. In particular, the global 2030 UN Agenda for Sustainable Development with its human-centred approach aimed at eradication of poverty, creating of possibilities for all and inclusiveness in the secure and prosperous environment, as well as the current Agenda for Europe, the relevant international legal base and practical tools are studied in their interconnection and complementarity. The article provides overviews of examples of good practice of “inclusive business partnerships” with sustainable social effect in some developing countries. The roles in this new economic practice of European and multinational economic entities as investors and promotors, international and local non-governmental organisations, international development agencies, and local power bodies are described. The relevance and socio-economic expediency of “inclusive business partnership” which is determined by the Sustainable Development Goals and the national economic and social background and which is ensured by the synergy of mutual possibilities, potential, needs and skills of its parties are argued. The eligibility of the necessary basic strategic-legal and socio-economic frameworks for learning the current foreign experience of the “inclusive business partnership”, elaboration of the relevant legal regulation and its implementation in Ukraine in the times of postwar recovery of Ukraine is generally analyzed. The author argues that the context of the comprehensive international support to Ukraine confronting the unprovoked Russian military aggression and the challenges of unprecedented losses, that is proved again during the London international Ukraine Recovery Conference of June 2023 and the declaration of the U.S. – EU Summit of October 2023, provide for the perspectives of Ukraine’s innovative, human-rights based, inclusive and ESG-oriented economic development in the course of its integration to the European Union. The nearest prospects of further research in the area of legal regulation of the “inclusive business partnership” in Ukraine are defined.

The features of distribution of uranium of albitites of the Novokostiantynivka and the Partyzanske deposits of the Central Ukraine Uranium Province of the Ukrainian Shield is considered in the paper. Ore layers of the Novokostiantynivka deposit have specific dark-colored minerals: top level — rybekite, aegerine, chlorite, epidote; bottom level — aegerine, biotite, magnetite, andradite. In albitites of the Partyzanske deposit there are wide-spread dark minerals such as rybekite, aegerine, actinolite, diopside, andradite; typical feature of the most of albitite types is a Fe-Ca garnet. No clear relation between uranium and thorium in albitites of the Novokostiantynivka deposit has been detected. It differs from albitites of the Partyzanske deposit, where several albitite types with strong correlation between uranium and thorium are observed: aegerine-andradite “ore” and rybekite-andradite-aegerine.

Published: December 2023

The mechanism of molecular complex formation in liquid propionic acid and its solutions is investigated. The anisotropic component of the Raman band of the C=O stretching vibration of pure propionic acid consists of three bands with maxima at 1661, 1700, and 1753 cm−1. The effect of varying the concentrations of solvents such as CCl4, acetonitrile, and water on this vibration mode is studied. The mechanism of formation of molecular complexes in solutions is determined using DFT calculations at the B3LYP/6-311++G(d,p) level of theory. The AIM, RDG, and NCI topological analyses are also performed to investigate the intermolecular interactions in the complexes.

Published: December 2023

A single composition of erbium-doped nickel zinc ferrite Ni0.5Zn0.5Fe1.95Er0.05O4 is synthesized by the sol-gel autocombustion process. The prepared composition was divided into five equal parts. One of the parts was an as-prepared sample, and remaining four other parts were calcinated at 600, 700, 800, and 900 ∘C to investigate the variation in structural and optical properties with the calcination temperature. The structural characterization was performed using XRD and SEM. Optical properties were analyzed using FTIR and UV-Visible spectral data. XRD patterns confirm the spinel cubic crystal structure and the Fd3m space group. The crystallite size was minimum for the as-prepared sample (17.9452 nm), and the crystallite size was maximum for the sample calcinated at 900 ∘C (29.8481 nm). SEM images revealed the grain size in the interval from 55.38 nm to 177.73 nm, and certain nanotubes were formed in the sample calcinated at 800 ∘C. Optical energy band gap was observed in the interval from 5.556 eV to 3.969 eV. All these testifies to the variations in structural and optical properties of Ni0.5Zn0.5Fe1.95Er0.05O4 with the calcination temperature.

Children with medical complexity (CMC) are a small but growing population representing <1% of all children while accounting for >30% of childhood health care expenditure. Complex care is a relatively new discipline that has emerged with goals of improving CMC care, optimizing CMC family function, and reducing health care costs. The provision of care coordination services is a major function of most complex care programs. Unfortunately, most complex care programs struggle to achieve financial sustainability in a predominately fee-for-service environment. The article describes how 2 programs in Wisconsin worked with their state Medicaid payer through a Centers for Medicare and Medicaid Services Health Care Innovation Award to develop a sustainable complex care payment model, and the value the payment model is currently bringing to stakeholders. Key elements of the process included: Developing a relationship between payer and clinicians that allowed for an understanding of each’s viewpoint, use of an accepted clinical service model, and an effort to measure cost of care for the service provided supported by time–study methodology.
Espiritualidade como Ciência
Authors: Piovezan Luis Henrique
Published: December 2023

A partir da análise do discurso do livro Despertar (2015), de Sam Harris, e da discussão de conceitos como “espiritualidade” e “religião”, o autor aborda as consequências das ideias do Neoateísmo, principalmente sobre a necessidade cientificamente determinada de se abandonar a religião. O pensamento de Sam Harris é comparado com as ideias de René Descartes e de Hannah Arendt. Com isso, aborda-se a cientificidade do livro Despertar e as consequências de suas ideias, que podem ser consideradas autoritárias sob o crivo de Hannah Arendt. Assim, buscando exemplos nos quais espiritualidade é tratada cientificamente, propõe-se um diálogo mais amplo entre os conhecimentos teológicos e os conhecimentos científicos.
Associação Portuguesa para o Progresso das Ciências (1917-1974)
Authors: Brandão Tiago , Rollo Maria Fernanda , Queiroz Maria Inês
Published: December 2023

A Associação Portuguesa para o Progresso das Ciências (APPC), criada em 1917 por iniciativa de Francisco da Costa Lobo, professor na Universidade de Coimbra, e com o apoio do astrônomo catalão Ricardo Cirera, foi diretamente inspirada pela Associação Espanhola para o Progresso das Ciências. A associação espanhola tinha sido constituída em 1908, organizando desde logo congressos bienais que reuniam diversos domínios científicos, por sua vez enquadrados em seções, procurando, desse modo, congregar as diversas áreas e promover a divulgação e o desenvolvimento do conhecimento científico. Através da nova associação portuguesa, seria então formalizada a participação de Portugal nos congressos da associação espanhola, dando lugar, a partir de 1921, à organização de encontros conjuntos – os “Congressos Luso-Espanhóis para o Progresso das Ciências” – cuja atividade se estenderia até os anos 1970. É o resgate da trajetória dessa instituição – encarada de forma integrada e global e interpretada no contexto da história geral das relações luso-espanholas – que pretendemos abordar neste estudo de caráter histórico e historiográfico.
Crise da democracia como separação da democracia e do liberalismo
Authors: Escaño Rodrigo
Published: December 2023

Este artigo analisa a crise da democracia contemporânea, focando na relação complexa entre populismo, tecnocracia e democracia liberal, mostrando que quando se fala em “crise da democracia”, na verdade, refere-se à crise da democracia liberal, ou à separação entre democracia e o liberalismo novamente, como era antes de elas se fundirem no final do século XIX. Será investigado como esses fenômenos interagem e afetam as instituições políticas e a estabilidade dos sistemas políticos em todo o mundo. O estudo considera a hipótese de que o crescimento do populismo e da tecnocracia representa uma ameaça à democracia liberal, examinando o grau de intensidade dessa tensão. A metodologia inclui uma revisão narrativa de obras teóricas relevantes, a síntese de seus principais pontos e a análise de fatores econômicos e políticos. Os resultados indicam que a ameaça varia entre países centrais e periféricos, sendo que de forma geral ainda é impossível decretar o fim dos regimes democráticos.

Published: December 2023

In this work, the dispersion properties and nonlinear properties of circular photonic crystal fibers were improved by a combination of carbon tetrachloride infiltration into the core and modification of the air hole diameters d1 and d2 of rings in the cladding. The quantities such as dispersion, effective mode area, nonlinear coefficient, and low confinement are analyzed in detail. Based on the survey results, two photonic crystal fibers with optimal optical properties were proposed which are beneficial for supercontinuum generation. The first fiber with Ʌ = 1.0 µm, d1/Ʌ = 0.6, has an all-normal dispersion of –10.785 ps/nm.km at a pump wavelength of 0.985 µm. The high nonlinear coefficient of 581.795 W–1.km–1 and the low confinement loss of 3.904 dB/m are also achieved with this fiber. SC broadband under the influence of soliton is expected to be generated when using the second fiber (Ʌ = 2.0 µm, d1/Ʌ = 0.3) with flat and low anomalous dispersion at the pump wavelength of 1.3 µm.

Purpose. Creating construction lines on the approaches to artificial structures, ensuring a smooth change of hardness gauge. Methodology. We consider the relationship between the size of the deposition area and the main module of deformation. Traditionally, the main precipitation area defined by methods that are based on the use of the method Shteynbrenera which is entitled «Method corner points». Module deformation determined from the dependence of modulus of elasticity. Latest thus determined practically. After analyzing both methods can give a clear conclusion that the module is inversely proportional to the deformation of sediment. Since the modulus of elasticity is dependent on the track deformation modulus of soil; then to achieve this goal can change the module deformation by replacing part of the soil crushed stone. Findings. Calculating the change of soil is simple, achieved the necessary smooth change of modulus of elasticity. Originality. A new method to improve the interaction of rolling stock and tracks in transition areas before the artificial structures. Practical value. Increased durability of structures built in the transitional areas to the artificial structures. Improved dynamic wheel-rail interaction, which in turn improves ride quality and durability of rolling stock.
Regional Differences in the Influence of COVID-19 Pandemic on Physical Activity Among Chinese Adults: A Social-Ecological Perspective
Authors: Nan Chen , Kim Chang Gyeong
Published: December 2023

PURPOSE: Physical activity confers benefits by mitigating the adverse physical and mental effects of coronavirus disease 2019 (COVID-19). Nevertheless, during a public health crisis, in which group-based physical activity is restricted, participation in such activities may be influenced not only by social distancing policies, but also by individual and environmental factors. As such, this study adopted a socio-ecological perspective to explore the impact of multidimensional factors on physical activity across diverse regions during the COVID-19 pandemic.METHODS: Cross-sectional data from the 2021 Chinese General Social Survey (CGSS) were used. A total of 8148 respondents from 12 provinces and metropolitan cities were pooled. Two types of physical activity (walking and moderate-to-vigorous exercise) were included in the statistical tests. A three-step hierarchical regression analysis was used to analyze the incremental predictive power of factors related to intrapersonal, interpersonal and community resources for physical activity.RESULTS: Findings highlighted the significance of intrapersonal (e.g., age, sex, socio-economic status, health status, and household registration area), interpersonal (e.g., neighborhood help and friendship), and community (e.g., exercise facility, fresh food accessibility, public facility, and residential safety) resources. These factors were significantly associated with Chinese adults’ participation in physical activity across various regions.CONCLUSIONS: Findings of this study provide an initial validation of the socio-ecological approach to studying physical activity during the COVID-19 pandemic, suggesting that strategies aimed at promoting the benefits of exercise should include multiple factors that influence the likelihood of Chinese adults engaging in physical activity.

ABSTRACT This article aims to investigate the behavior of exchange rate in the BRICS countries, with an emphasis on exchange rate passthrough and exchange rate determination empirical models. By applying the ARDL Bounds Testing Approach Methodology, from January 2005 to December 2019. Our main results show that: i) there is a long run cointegration among the variables analyzed for all estimated models; ii) there is a very slow speed of adjustment towards the long run equilibrium; iii) there is evidence of exchange rate passthrough to inflation mainly in the long run, but not as strong as before; iv) there is no evidence of exchange rate overshooting; v) international reserve accumulation can be considered a partial explanation for the evidence of no exchange rate overshooting.

ABSTRACT: Okra is a vegetable that stands out for its low production cost, high yield, high nutritional and value and socioeconomic importance in income generation, especially in family farming. In this context, the present study evaluated the physiology, production and water use efficiency of okra under irrigation with saline water and exogenous application of hydrogen peroxide. The treatments were distributed in a randomized block design, in a 5 × 3 factorial arrangement, with five levels of electrical conductivity of irrigation water - ECw (0.3; 1.3; 2.3; 3.3 and 4.3 dS m-1) and three concentrations of hydrogen peroxide - H2O2 (0, 25 and 50 μM), with five replicates, totaling 75 plants. Irrigation with ECw above 0.3 dS m-1 negatively affected stomatal conductance, transpiration, number of fruits, total production and water use efficiency of okra cv. Clemson Americano 80. Hydrogen peroxide at concentration of 22 μM mitigated the effects of salt stress on CO2 assimilation rate, number of fruits, average fruit weight and total production of okra cv. Clemson Americano 80. Water use efficiency is favored by H2O2 application at concentration of 12 μM, especially in plants irrigated with ECw of 0.3 dS m-1.

ABSTRACT: We use the ARIMA-GARCH model to estimate the shocks of COVID-19 on Chinese agricultural markets and utilize the ARDL-ECM model to estimate the integration relationships between Chinese and international agricultural markets which are based on the effective market hypothesis theory and daily trading data of US, UK, China and India. The main study findings showed that COVID-19 has a significant negative impact on agricultural product market, specifically, India suffered with the greatest negative impact, followed by the UK, the US and China. Further, this study results revealed that Chinese grain markets that are considered strategic places have not been separated from international markets, but there still exist segmentation phenomena among non-strategic agricultural markets.
Nutrient parameters limiting banana plant development in Vale do Ribeira, São Paulo State, Brazil
Authors: Oliveira Cibelle Tamiris de , Rozane Danilo Eduardo , Lima Neto Antonio João de , Natale William
Published: December 2023

ABSTRACT: Vale do Ribeira is one of the largest banana producing regions in Brazil. However, information on soil fertility and nutrient status that could limit fruit production remains scarce. Thus, the present study diagnosed the most limiting nutrient parameters for the Nanica and Prata banana cultivars, in Vale do Ribeira, São Paulo State, based on soil and leaf chemical analyses. The data assessed included samples from commercial plantations in the municipalities of Eldorado, Cajati, Jacupiranga, Pariquera-açú, Registro and Sete Barras, between 2012 and 2020. The results of soil (pH, V, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn) and leaf chemical analyses (N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn) were interpreted according to literature values and their maximums, minimums, means, coefficients of variation (CV), and confidence intervals (CI) were calculated at P < 0.05. Parameter classes were assessed according to their frequency distribution. A large part of the samples exhibited pH and V values similar to those recommended for banana plants. Although, average soil nutrient concentrations were considered high, soil K, Mg and S levels did not provide adequate banana plant nutrition, since these nutrients were deficient in the plants.

ABSTRACT: Leptospirosis, a disease of significant economic impact on livestock and public health concern, may exhibit unique epidemiological characteristics in indigenous villages, particularly those located within semiarid climates such as the Caatinga biome in Brazil. This environment often presents conditions unfavorable for leptospire survival. This study conducted serological diagnoses of livestock in indigenous villages within the Caatinga biome, Northeastern Brazil. The survey was carried out in the Mãe Maria and Santa Helena indigenous villages, home to the Xukuru de Cimbres tribe, in the county of Pesqueira, Pernambuco State, Brazil, within the Caatinga biome. Blood samples were collected from cattle (n = 42), goats (n = 41), and sheep (n = 19). Out of the 102 samples tested, 73 (71.6%; 95% CI = 62.8% - 80.3%) were seroreactive (cut-off ≥ 100). The seropositivity rates for cattle, goats, and sheep were 54.8%, 80.5%, and 89.5%, respectively. A statistically significant difference was observed in the proportion of seropositive animals between cattle and goats and cattle and sheep (P < 0.05). Icterohaemorrhagiae was identified as the most probable serogroup across all animal species. The study revealed that livestock in indigenous villages within the Caatinga biome are frequently exposed to leptospires. This finding underscores the importance of a One Health approach, emphasizing the need for comprehensive studies in areas where large human and animal populations coexist. Such studies are crucial for investigating zoonotic infections and for planning and implementing control measures against livestock-associated leptospirosis.
Different extension organizations in Türkiye: Aegean region example
Authors: Boyaci Murat , Yildiz Ozlem
Published: December 2023

ABSTRACT: This study assessed different extension actors in the Aegean region in terms of key indicators that influence the success of extension activities. Along with the primary goal, factors affecting extensionists’ satisfaction with their working conditions were investigated. The data were collected through questionnaires from 966 extensionists working in public, private firms, farmer organizations, input dealers and consultancy in eight provinces in the region. According to the results, 80% of the farmers received extension services from public organizations in the region. While those who work in the public sector are more satisfied economically, their professional satisfaction is the lowest. Extension workers’ personal skills, sharing ideas, creativity, and authority-responsibility harmony, working freedom, staff availability and support are increasing satisfaction with working conditions in organizations. While female farmers are targeting more by the public and consultants, educated farmers are more prioritized in firms, dealers, and consultations. The internalization of innovative values is lower in the public organizations compared to the others. It is foreseen that; the public will carry out extension in developing countries for a long time. The success in extension organizations, the innovation process and pluralistic structure became quite more dependent on the relations with the private sector, domestic and international market mechanisms, demand driven giving advice and government policies on social, economic, and environmental.

ABSTRACT: Pythiosis is the disease caused by aquatic oomycetes of the genus Pythium. In dogs the typical course of the disease involves the gastrointestinal tract, characterized by transmural thickening of the stomach or intestines. However, infection by Pythium spp. has only rarely been recognized as a cause of esophagitis in dogs. Thus, the present reports a case of esophageal and gastric pythiosis in an eight-month-old female pit bull dog. The dog was attended at the hospital after two months presenting regurgitation and dyspnea. It was reported that the dog lived in an urban area and had no previous sanitary issues. At clinical examination it was noted that the dog presented crackling sounds at pulmonary auscultation. A support therapy accompanied by antibiotics has been employed; however, 22 days after hospitalization the clinical condition worsened, and the dog died. At necropsy, the wall of the distal segment of the esophagus and the cardia and part of the fundus of the stomach were expanded by a focal extensive irregular intramural annular mass. Additionally, there was a transmural esophageal fistula. At histology, the walls of the esophagus and stomach were extensively expanded by multifocal extensive areas of necrosis, associated with a pyogranulomatous infiltrate and abundant granulation tissue containing multiple negative images of hyphae that were highlighted by silver impregnation (Grocott). Furthermore, immunohistochemistry and PCR for P. insidiosum were both positive in samples of paraffin-embedded esophageal tissue.

Abstract Cowpea is one of the main crops in family agriculture, especially in the Northeastern region of Brazil, and it is expanding to other regions in Brazil. The use of seeds with low physiological and health quality is reflected in the plant development and consequently yield, making it important to study the seed physiological and health quality. The objective of the present study was to assess the physiology and health of traditional and biofortified cowpea seeds. The traditional cowpea varieties (Angelim, Mercado and Manteguinha) and the biofortified cowpea cultivars (BRS Aracê, BRS Xique-Xique and BRS Tumucumaque) were assessed for the following physiological parameters: water content (WC), first count (FC), germination test (G), germination speed index (GSI), seedling emergence in the greenhouse (E), emergence speed index (ESI), seedling aerial part and root length (APL and RL) and electric conductivity test (EC). The seed health quality was assessed by the Blotter Test. The water content present in the seeds of the traditional and biofortified varieties ranged from 10% to 14%. All the traditional and biofortified varieties showed high germination and emergence value in the greenhouse. The germination and emergence speed indexes indicated the BRS Aracê and BRS Xique-Xique cultivars as the most vigorous. In the health tests the highest indexes were the storage fungi Aspergillus sp., Cladosporium sp. and Penicillium sp., with the highest prevalence in the BRS Tumucumaque variety, which was probably related to the higher water content present in this variety.
Effects of previous infestation with Bemisia tabaci MEAM1 on the resistance to Chrysodeixis includens in Bt and non-Bt soybean plants

Abstract Transgenic Bt soybean plants have been developed to control insect pests, such as Anticarsia gemmatalis and Chrysodeixis includens. This objective has been achieved successfully; however, recently, some authors claimed that Bt soybean plants have been more susceptible than non-Bt soybean to Bemisia tabaci MEAM1. In addition, it is unknown whether Bt soybean plants infested by B. tabaci become less resistant to target pests. Therefore, this study aimed to evaluate: (i) whether the previous infestation with B. tabaci can compromise Bt and non-Bt soybean resistance to C. includens; (ii) the effects of B. tabaci infestations on Bt and non-Bt soybean plant growth; and (iii) whether B. tabaci feeding reduces contents of chlorophyll and carotenoids of soybean plants. Bt and non-Bt soybean plants pre-infested with B. tabaci showed no changes in resistance to C. includens. Bt soybean plants infested with B. tabaci showed a lower plant height than uninfested plants. Differently, non-Bt soybean plants exhibited no reduction in plant growth due to B. tabaci feeding. Bt soybean plants suffered a reduction in dry matter only under double infestation (B. tabaci and C. includens), while non-Bt soybean plants experienced reduction in dry matter when infested with B. tabaci and C. includens or by C. includens only. B. tabaci feeding did not alter contents of chlorophyll and carotenoids, and perhaps the reduction in plant growth was related to salivary toxins. Concluding, both Bt and non-Bt soybean plants were susceptible to B. tabaci feeding, evidencing necessity of developing soybean cultivars resistant to B. tabaci.

Abstract Low density sugarcane plantation (LDSP) has been implemented by some sugarcane producers in Brazil, aiming to save seeds and operational costs. The study was carried out in the municipality of Areia, Paraíba, Brazil. Five planting densities were used, varying from 5 to 25 m-2 of buds arranged in randomized blocks, with four replications. Data were measured annually over three cultivation cycles (2017 to 2020), during which the field was fertilized with NPK and the harvests were carried out manually without prior burning. The lower planting density presents higher productivity only in the cane plant (101.03 t ha-1) due to the higher plant height (2.37 m) and the higher number of stalks (11 stalks m-2), suggesting that these variables are due to the greater availability of light, water and photosynthate. However, there is a drastic reduction in sugarcane yield for this lower population in the 2nd ratoon by up to 65.62%, which is correlated with number of stalks per meter. We demonstrate the agronomic viability of LDSP in the population of 10 buds m-2 in relation to conventional planting of sugarcane until the 2nd ratoon. Data are important for future studies to present additional considerations for other production factors, such as the effects of mechanized harvesting and the management of nutrients and water, assessing the sustainability of this large-scale planting system.

Desde sua construção em 1887 por Albert Michelson e Edward Morley, com o objetivo de medir a velocidade da terra em relação ao éter, o interferômetro de Michelson-Morley passou a ser utilizado nas mais diversas aplicações de interferometria. Apesar de sua simplicidade na montagem, o instrumento encontra importantes aplicações utilizando o fenômeno de interferência. Neste trabalho apresentamos a simulação e a construção de uma variante do interferômetro de Michelson-Morley utilizando o dioptro ar-água como divisor de feixe. A proposta é uma importante aplicação para discussão de diferentes temas vistos na formação em Física e Engenharias. Na montagem foram utilizados um laser vermelho centrado em 630 nm, com polarização linear orientada em um ângulo de cerca de 45∘ do plano de incidência, como fonte de excitação e dois espelhos de primeira face para refletir os feixes refletido e o refratados no dioptro. A análise das intensidades das ondas foi realizada utilizando o Método dos Elementos Finitos e as imagens das interferências circulares foram obtidas utilizando-se uma câmera CCD.
From “Tough Love” to “Street Fight”: Garret Hardin and Cordelia S. May’s Battle for Population Control and Eugenics at the Turn of the Millennium
Authors: Chavez-Garcia Miroslava
Published: December 2023

ABSTRACT This essay draws on epistolary documentation, conference proceedings, and U.S. government reports to analyze the correspondence of right-wing “conservative” activists Garrett Hardin and Cordelia S. May, focusing on their obsession with population control and eugenic principles as solutions to the growing ecological disasters of the 1960s through the early 2000s. These individuals engaged in negotiations and made decisions that helped shape public support for draconian population control policies and practices based on eugenics. These sources provide new insights into how a group of influential intellectuals, financiers, and self-proclaimed environmentalists worked to build a white, elite, heteronormative, and empowered smart society for the future, despite their inability to keep population control on the national agenda.
Assunção de Callado: inserção e modos de engajamento no meio artístico
Authors: Queler Jefferson José
Published: December 2023

RESUMO Antonio Callado e seus escritos, de maneira geral, são interpretados por analistas como pertencentes ao campo da esquerda. Entretanto, seus primeiros trabalhos no jornalismo, na dramaturgia e na literatura, quando inseridos nos respectivos campos em que foram concebidos, denotam orientações ideológicas e estéticas conservadoras. Conforme evidências de parte da correspondência - inédita - trocada entre ele e intelectuais de grande projeção pública entre as décadas de 1950 e de 1960, é possível sugerir que Callado, posicionando-se dessa forma, teceu laços com intelectuais de diferentes tendências políticas e artísticas e, assim, conquistou posições mais proeminentes no âmbito da impressa e das letras. Desse modo, os sentidos de suas variadas formas de engajamento poderiam ser compreendidos sob outra ótica.

ABSTRACT The objective of this work was to evaluate the application efficiency of different nozzle tips associated with increasing application rates. A field experiment was conducted in a factorial 3 × 4 randomized block design with four replicates. The first factor consisted of three types of nozzle tips (simple flat fan, hollow cone, and hollow cone with the electrification of the drops), and the second factor constituted the four application rates (50, 100, 200, and 250 L ha-1). Electrostatic technology and a hollow cone tip increased the deposited volume on leaves on the upper and medium strata of the common bean plant, regardless of the application rate used. The increase in the application rate increased the volume of spray solution captured in the upper, medium, and lower strata, the drop density, the volumetric median diameter (VMD), and the percentage of foliar coverage, regardless of the spray tip evaluated. The percentage of leaf coverage on the adaxial and abaxial leaf was not influenced by the simple fan or hollow cone spray tips, with or without the association of electrostatic technology.

ABSTRACT Applications of tebuthiuron can increase the risks of environmental contamination and hinder the cultivation of sensitive species in succession. The objective of this work was to assess the residual activity and sorption of the herbicide tebuthiuron in soils with different physical and chemical attributes. The experiments were conducted in a completely randomized design with four replicates. The experiment for determining residual activity was conducted in a 2 × 7 factorial arrangement consisted of two herbicide doses (0.6 and 1.2 kg a.i. [active ingredient] ha-1) and seven sowing times (0, 60, 120, 180, 240, 300, and 360 days after herbicide application) in sandy loam and sandy clay loam soils. The experiment for evaluating sorption was conducted in a sandy loam soil and two clay loam soils with applications of increasing tebuthiuron doses (0.025, 0.05, 0.10, 0.15, 0.20, 0.25, 0.30, 0.35, 0.40, 0.50, 0.60, 0.70, and 0.80 kg a.i. ha-1). Regarding residual activity, the herbicide’s effect of the decreased over time, with no toxicity detected 360 days after application (DAA), regardless of the soils and doses used. Sandy loam soils had lower sorption, resulting in lower shoot dry weight and plant height and in higher phytotoxicity 21 days after emergence. Residual activity was detected 360 DAA in the studied soils. Tebuthiuron sorption was higher in soils with higher organic carbon and clay contents.
DESENVOLVIMENTO CONVIDADO OU PROJETADO? DEPENDÊNCIA, ESTADO E CAPITAL NACIONAL NO DESENVOLVIMENTO CAPITALISTA NA COREIA DO SUL
Authors: Moreira Uallace , Bastos Pedro Paulo Zahluth
Published: December 2023

RESUMO A Coreia do Sul sempre é apontada como exemplo de país que superou a armadilha da renda média, com upgrading da estrutura produtiva dominada por conglomeradores nacionais (chaebols) e inserção internacional altamente competitiva. Como isso ocorreu é objeto de debate acadêmico caloroso. Neste artigo, identificamos três linhas de interpretações: i) neoclássica/neoliberal, a qual defende que a economia sul-coreana foi regida pelo livre-mercado, principalmente a partir dos anos 1980; ii) heterodoxa endogenista, a qual aponta o protagonismo do Estado; iii) dependentista radical, que enfatiza a característica positiva e determinante do contexto externo. Alternativamente, realçamos uma forma de associação dependente com a potência hegemônica (os Estados Unidos) que propiciou o controle oligopolista de empresas de capital nacional dos ramos líderes da indústria de transformação. Tal associação não pode ser entendida sem referência a conflitos sociais na península coreana e, em particular, à política do governo Park Chung-hee (1961-1979) em relação à estrutura de propriedade do capital e ao projeto de alcance da autonomia tecnológica. Mesmo depois das reformas liberalizantes forçadas em parte pela potência hegemônica nas décadas de 1980 e 1990, o controle oligopolista de empresas nacionais dos ramos líderes da indústria de transformação permaneceu fator estratégico para a manutenção da autonomia tecnológica e para a aliança entre os chaebols e o Estado na disputa global por mercados.
POLÍTICA INDUSTRIAL E DESINDUSTRIALIZAÇÃO NO BRASIL: INSPIRAÇÕES DE DAVID KUPFER AO DEBATE
Authors: Lacerda Antonio Corrêa de , Severian Danilo
Published: December 2023

RESUMO O artigo discorre sobre os processos de especialização regressiva e desindustrialização precoce que acometem a estrutura produtiva do país, tendo como motivação as contribuições trazidas por David Kupfer às reflexões e proposições de políticas industriais e de inovação, tratadas em sua obra como meio para o desenvolvimento nacional, e não como um fim em si. À luz dessas reflexões, fazem-se conjecturas para o debate público sobre a retomada do desenvolvimento econômico por via da reindustrialização. A partir de uma breve introdução, o artigo se subdivide em três seções. A primeira, Especialização regressiva e desindustrialização precoce: Reflexões para o caso brasileiro, traz um diagnóstico do processo de perda de substância industrial na economia e seus desdobramentos; a segunda, Boom das commodities: Impactos no câmbio, nos termos de troca e na balança comercial da indústria brasileira, busca análise mais pormenorizada do problema da reprimarização da estrutura produtiva brasileira; a terceira, Considerações finais: Reflexões para a retomada da indústria e do desenvolvimento econômico, apresenta, à guisa de conclusão, contribuições para uma agenda de debates sobre as questões tratadas ao longo do artigo.

Abstract The political changes that have taken place in Bolivia in the last fifty years have led to modifications in the participation of subalternized groups and changes in the ethical appreciation of life. This study aims to establish the bioethical behaviors of the Andean cosmovision in acculturated, endoculturated and transculturated people in La Paz, Bolivia. It is a mixed, exploratory, ethnographic, cross-sectional, comparative, synchronic, diachronic and systematic research, in which a questionnaire validated by experts (Cronbach’s alpha 0.932) was applied to 399 people (5.3% acculturated; 73.9%, endoculturated and 20.8%, transculturated). The results contrasted by hermeneutics obtained five categories, of which the category relationality was independent of acculturation (p=0.262); while the categories ecological awareness, complementarity, reciprocity, concept of health, social model and community depended on each other (p=0.000). It was found that the acculturated subjects from the rural area presented greater knowledge of ancestral ethics. The promotion of educational policies related to ethics is recommended.
