Published: December 2024

O estudo analisou os fatores que levaram o Grupo Cereal, agroindústria do estado de Goiás, a aumentar sua recepção de grãos de soja em 16,92% entre as safras de 2021/2022 e 2022/2023. Utilizando uma metodologia mista, combinando análises qualitativas e quantitativas, foram examinados dados extraídos de relatórios e planilhas da empresa. Dentre os principais fatores para o crescimento, destacou-se a duplicação do número de armazéns de terceiros, o que permitiu uma maior capacidade de armazenamento e melhor gerenciamento logístico. Outro fator crucial foi a operação do terminal ferroviário RUMO em Rio Verde, que facilitou significativamente o escoamento dos grãos, especialmente para exportação, contribuindo para a liberação de espaço nos armazéns e para a redução de custos operacionais. Além disso, a expansão da frota de transporte, com a aquisição de novos caminhões e a contratação de transportadoras terceirizadas, foi essencial para atender à crescente demanda. Apesar dos avanços, o Grupo Cereal ainda enfrenta desafios, como filas nos armazéns e limitações estruturais. O estudo ressalta que o crescimento é fruto de um modelo logístico integrado e estratégico, que pode servir de exemplo para outras agroindústrias. Para sustentar esse progresso, recomenda-se a continuidade de investimentos em inovação, automação e expansão da infraestrutura logística, com foco em eficiência e sustentabilidade.

A depressão é um dos principais indicadores de adoecimento psíquico na atualidade, com uma prevalência considerável e um impacto significativo na vida das pessoas. Além disso, a ansiedade, quando patológica, pode levar a vários transtornos que afetam negativamente a vida do indivíduo. Considerando o contexto laboral, onde as vivências subjetivas influenciam não só no ambiente de trabalho, mas também na vida pessoal, é essencial abordar os transtornos mentais nesse contexto. O presente estudo investigou a prevalência de sintomas de depressão e ansiedade entre os colaboradores de uma Instituição de Ensino Superior (IES), localizada no sudoeste goiano. Participaram 100 colaboradores, divididos entre técnicos administrativos e docentes. Utilizou-se como instrumentos um Formulário de Coleta de Dados e os Inventários de Ansiedade e Depressão de Beck. Os resultados indicaram que a média de resposta dos participantes nos instrumentos que medem depressão e ansiedade foram 15,83 e 10,85. Contudo, 53% dos colaboradores apresentam algum nível de depressão. Além disso, maiores índices de ansiedade foram encontrados em pessoas que não praticam atividade física e sentem falta de reconhecimento no trabalho. Ao investigar associação entre depressão e ansiedade com variáveis sociodemográficas, encontrou-se que pessoas mais jovens e com menos tempo na IES tiveram nível mais elevado de depressão, assim como ansiedade com menor nível em pessoas que dormem mais. Desse modo, é evidente que o bem-estar dos colaboradores está prejudicado, destacando a necessidade de adotar medidas de suporte e cuidado para melhorar essa condição, que influencia diretamente a vida e a eficiência dos servidores.

A papada, caracterizada pelo acúmulo de gordura subcutânea abaixo do queixo, representa uma preocupação estética com repercussão na autoestima dos indivíduos afetados. Nesse contexto, o ozônio, reconhecido por suas propriedades terapêuticas, surge como uma abordagem promissora para tratamento da adiposidade localizada na região submentoniana. Pesquisas indicam que o ozônio pode induzir a lipólise e reduzir o volume adiposo, através de suas propriedades lipolíticas e estimulantes da circulação local. Este artigo tem o objetivo relatar um caso clínico de ozonioterapia como tratamento não invasivo para a papada, destacando sua eficácia e segurança baseadas em estudos científicos. Paciente do sexo feminino, 23 anos, compareceu a Clínica Odontológica da Universidade Estadual do Oeste do Paraná com queixa estética, apresentando a região de papada saliente. O tratamento compreendeu um protocolo de 6 aplicações de gás ozonizado em 3 pontos, sendo realizada uma aplicação por semana. Os resultados mostraram que após o tratamento com ozonioterapia na região da papada, apresentou uma redução muito expressiva da região submentoniana tratada. Contudo, o ozônio deve ser considerado um tratamento complementar para a redução de gordura localizada. A combinação com exercícios físicos regulares e uma alimentação saudável é essencial para o sucesso na perda de peso e na redução de gordura. A ozonioterapia, nesse contexto, se mostra uma excelente aliada para a eliminação de gordura localizada, como a adiposidade submentoniana, promovendo a lipólise e, quando associada a hábitos saudáveis, proporciona resultados ainda mais satisfatórios.

Jurisprudence of constitutional values: origin, criticism and defense against it
Authors: Belov Sergei A.
Published: December 2024

Values approach to the substance and interpretation of constitution origi-nates from Weimar Germany and after World War II was adopted and applied by the Federal Constitutional Court (Bundesverfassungsgericht) soon after it’s establishing. De-claring the constitution as “objective order of values” inspired legal scholars in Germany and abroad to develop the value theory of law and borrowed by courts of Brazil, South Africa, Israel, Venezuela and Russia. At the same time jurisprudence of values became an object of sharp critics, manifested in a book published in Germany in 1960 by Carl Schmitt — Tyranny of values and later developed by other authors. Opposing their argu-ments, author defenses the values method of constitutional interpretation and describes the features and specificity of thinking about constitution as a system of values. Author reasons that values are not aggressive, do not pretend to dominate over norms and prin-ciples and are not subjective. The author’s position supports the idea that values choice is not rational, while states that this does not impede to keep law certain and predict-able — if the values, found by courts behind the legal norms and principles and applies in concrete cases, will be explicitly defined and consequently and non-contradictorily realized in judicial practice
Digital actors and computational propaganda as tools for influencing mass consciousness in the context of global technological transformations
Authors: Volodenkov Sergey Vladimirovich
Published: December 2024

The main goal of this article was to identify the potential and features of the use of digital actants and computational propaganda technologies in contemporary processes of digital socio-political communication. Current digital technological transformations and the rapid evolution of artificial intelligence technologies are powerful factors and drivers of the development of digital actants — software and hardware systems operating on the basis of the use of neural network algorithms and taking an active part in the processes of digital socio-political communication. In this regard, such new type of actants require careful study by specialists and scientists. In the framework of this work, the methodological basis of the study was the methods of discourse analysis, case study, and expert survey, which made it possible to confirm the results we obtained. The work demonstrates that digital actants have a substantial potential to impact mass consciousness and behavior. It is determined by the high efficiency of algorithmically adapted information and communication influence from “smart” communicative actants on the target audiences’ consciousness. Such potential is based on the algorithmic analysis of users’ digital traces and the identification of subjective features and characteristics of the latter. Based on the results of the work, it is concluded that contemporary digital technological transformations create a significant potential for computational and propaganda wars in the digital environment between global political actors. This circumstance leads us to the thesis about the need to ensure state technological sovereignty in the digital space.

The Effects of Emotion Regulation on Non-suicidal Self-injurious
Authors: Ge Ge
Published: December 2024

Non-suicidal self-injurious behaviours affect people's physical and mental health and are known to show a high incidence globally. Based on emotion regulation theory and the emotion cascade model, this study focused on the effects of four different emotion regulation strategies, namely cognitive reappraisal, expressive suppression, impulsivity, and rumination, on non-suicidal self-injurious behavior. Combined with magnetic resonance imaging, event-related potentials, and electrophysiological techniques, functional abnormalities in brain regions such as the amygdala, prefrontal cortex, and cingulate cortex, abnormalities in electroencephalographic indexes, and functional abnormalities in the autonomic nervous system are potential mechanisms by which emotion regulation affects NSSI. Future research should use objective measures, incorporate longitudinal studies, expand the study to clinical samples, and conduct culturally diverse studies.

Published: December 2024

Ursodeoxycholic acid (UDCA) is a widely used pharmacologically active natural bile acid, which can dissolve cholesterol gallstones and improve liver function in cases of cholestasis. UDCA was originally obtained from the bile of live bears, but environmental and animal welfare concerns have made this source increasingly problematic, and increased demand for alternatives. Today, chemical and enzyme-catalyzed syntheses are often used to produce UDCA. Research hot topics have concentrated on UDCA-related precursors with plentiful sources and affordable prices due to the significance of UDCA in the drug treatment of human cholesterol stones and other associated disorders. In this review, the state of research on the chemical and biological synthesis of UDCA from different materials [cholic acid (CA), chenodeoxycholic acid (CDCA), hyodeoxycholic acid (HDCA), etc.] is summarized and analyzed, to guide and inform future research on commercial UDCA production.

Published: December 2024

Using ‘Chardonnay’ grape as the test material, the field plot experiment method was used to set up four treatments: biocontrol group (Beauveria bassiana fungicide A and B), pesticide group (cypermethrin) and blank control (CK). The insecticidal effect of biocontrol agent and pesticide was compared by investigating the number of grape maculatus cicada and aphids after spraying twice in spring. To explore the potential of biocontrol fungi for grape hemiptera pest control, in order to provide reference for biocontrol agents for grape pest control. The results showed that biocontrol agents Group A and B both achieved the best control effect on spotted lanternfly and aphids after 9 days. The control effect of agent A was 97.65%、95.64%, respectively, and agent B was 96.57%、97.51%, respectively. The control effect of the high cypermethrin pesticide group reached the best effect on the 6th day, but with the increase of spraying time, the control effect increased first and then decreased. The half-lethal time (LT50) of the pesticide group was 2.5 ± 0.05 d、2.17 ± 0.29 d, respectively, and the LT50 of agent A group was 4.67 ± 0.29 d、4.83 ± 0.29 d, the LT50 of agent B was 4.83 ± 0.58 d、4.17 ± 0.29 d, respectively. In conclusion, Beauveria bassiana spray had better control effect on Spotted Lanternfly and grape aphids than the pesticide cypermethrin, and there was no significant difference in control effect between the stable groups, but the insecticidal quick effect was relatively poor.

Multibeam bathymetry based on multiple geometric models and coverage overlap analysis
Authors: Liu Ye , He Qiwei
Published: December 2024

In this paper, we mainly study the multibeam bathymetry bandwidth and overlap rate calculation and the optimization of survey path schemes under different sea conditions. Based on the basic idea of constructing different geometric mathematical models, the geometric relationship between adjacent multibeam survey strips is expressed, and then the plane geometric model for calculating the measurement bandwidth and overlap rate between adjacent strips is established; the three-dimensional simulation scheme of multibeam bathymetry and three-dimensional simulation diagrams of profiles with special geometric relationship are drawn, and the three-dimensional slope is reduced to a two-dimensional plane based on the geometric relationship of space, and the spatial angle is calculated to obtain the three-dimensional geometric model. The three-dimensional geometric model is obtained by calculating the angle between the survey paths and the normal plane of the seabed slope according to the idea of plane geometry. To validate the model of a single slope, a system of nonlinear equations is then set up and solved using an iterative algorithm to obtain the shortest survey path that realizes the full coverage of the measurement. A scatter fit is applied to prove that it conforms to the geometric law..
Occurrences, Distributions, Origins and Forming Mechanisms of Calcite Cements in Upper Triassic Yanchang Formation Sandstones, Ordos Basin
Authors: Zhou Xiaofeng , Li Tao , Xiao Wenhua , Wei Jun , Yan Baonian , Yu Junmin
Published: December 2024

In view of the important influence of calcite cements on the physical properties of sandstone reservoirs, their material sources and formation mechanisms have always been a research hotspot but remain unresolved. Taking the sandstone reservoir of Yanchang Formation of Upper Triassic in Ordos Basin as an example, this paper studies the occurrences, distributions, material sources and formation mechanisms of calcite cements. The Yanchang Formation sandstones, according to the color property of the cores, are divided into the grey sandstone and the grayish brown sandstone. The calcite cements in these sandstones, based on their occurrences by optical microscopy, can be divided into three groups: the disseminated calcite cement in the grey sandstone, the patchy calcite cement in the grayish brown sandstone, and the calcite vein in the fracture. In a sand body, the grayish brown sandstone with the patchy calcite cement is surrounded by the grey sandstone with the disseminated calcite cement. Although the occurrences of these calcite cements are different, all of them originate from the adjacent mudstones during the compaction. The patchy calcite cement forms by the episodic fluid from the adjacent muddy sediment with the fracture acting as the mass transfer path and subsequently the calcite vein fills in the fracture. Then the disseminated calcite cement precipitates with the steady flow in the contact of the nearby muddy-sandy sediments. This investigation of the calcite cements can well explain the varieties of their occurrences and distributions and compositions in Upper Triassic lacustrine Yanchang Formation sandstones, which is beneficial to confirming the information of calcite cements in other lacustrine sandstones.

A Study on the relationship between Landscape Elements, Landscape Preferences and Health Benefits in Urban Parks
Authors: Wen Yu , Li Yulan , Liu Bingbing , Long Tao , Hu Jianyu
Published: December 2024

Public health and well-being are closely linked to the quality of the human landscape environment. As a vehicle for studying human-landscape interactions, landscape preferences are closely linked to landscape resilience. Numerous studies have shown that individuals exhibit different preferences for different environments, with more preferred environments producing greater health benefits. Natural environments are also subject to differences in individual preferences and offer greater health benefits than urban environments. To investigate the relationship between landscape elements, landscape preferences, health benefits and their influence mechanisms, an influence pathway and evaluation model was constructed for this study between these three variables, using the South Lake Urban Central Ecological Park in Tangshan, China as the research object and social media network evaluation as the data source. Quantitative and qualitative analyses were used to extract landscape element measures, in combination with existing landscape preference and health benefit assessment scales. Field research was conducted to obtain evaluation data, and a structural relationship model was constructed for validation to examine the interactions between landscape elements, landscape preferences, and health benefits. The results showed that landscape elements had a significant positive effect on landscape preferences (β is 0.699, t=8.375, P<0.001); landscape preferences also had a significant positive effect on health benefits (β is 0.643, t=6.526, P<0.001); landscape elements also had a significant positive effect on health benefits (β is 0.42, t=2.816, P< 0.01), while landscape elements had an indirect effect through partial mediation of landscape preferences. In the landscape element measurement model, each latent variable can effectively explain landscape elements, but the explanation ability of each latent variable for landscape elements varies, indicating that different landscape elements have different effects on landscape preferences; in the landscape preference measurement model, the four measurement dimensions can effectively explain landscape preferences, among which consistency has the highest explanation ability for landscape preferences; in the health benefits assessment measurement model, all four measurement dimensions effectively captured the health benefits assessment, eliminating fatigue has the highest explanatory power for the health benefits assessment. From the final structural equation model, it can be seen that landscape elements have a significant effect on both landscape preferences and health benefits, and landscape preferences also has a significant effect on health benefits. Visitors moved from landscape element evaluation to landscape preferences and finally to health benefits assessment, which is a sequential experience.

The instability and failure laws of karst roadbeds under development conditions and the control effect of concrete cover plates on karst roadbed settlement were studied. Research has shown that the maximum displacement of karst roadbeds occurs at the top of the karst cave. With the continuous development of the karst cave, the displacement at the top of the cave increases, leading to settlement deformation of the roadbed surface and ultimately resulting in roadbed collapse; During the development of karst caves, the vertical soil pressure of the roadbed at positions 0cm and 10cm from the centerline decreases with the increase of cave span, while the vertical soil pressure of the roadbed at positions 20cm and 30cm from the centerline increases with the increase of cave span; Even with the continuous development of karst caves, the karst treatment effect of concrete cover plates is still very obvious.

Ammonia nitrogen pollution in rivers is increasing day by day, and the use of plants to remove ammonia nitrogen from water bodies in large-volume sewage is a more common method.However, there are many problems in ecological methods such as traditional constructed wetlands.Therefore, the results of pilot experiments in this paper show that (1) the spatial intensification of the system: Combined with multi-level artificial ecological technology and three-dimensional hydroponic technology, a three-dimensional artificial ecosystem is constructed to maximize the use of vertical space, increase the system space and hydraulic residence time, reduce the area of more than 75% compared with traditional ecological wetlands, and exert efficient pollutant reduction ability in a small area.(2) High nitrogen removal efficiency of the system: The introduction of plant root zone microbial culture and domestication technology in the process of ecological plant culture can improve the nitrogen removal capacity of the three-dimensional ecosystem, and the ammonia nitrogen degradation rate can reach up to 96%, stably reaching the surface water environmental quality standard (GB 3838-2002) Class IV water quality.(3) To achieve low temperature and stable operation in the northern winter: Capping photovoltaic glass greenhouses outside the three-dimensional ecosystem to ensure the operating temperature of the ecosystem in autumn and winter, ensuring that the system can maintain a high water temperature at night in winter, and promoting microbial nitrogen removal and plant growth.④ Ecological and economic value: The solar photovoltaic system is set on the greenhouse, and the solar photovoltaic technology is used to provide electricity for the ecosystem.The effluent treated by the system is used for the water of flowers and plants in the system.The labor cost and equipment maintenance cost during the operation of the system are compensated by the income from the sale of flowers.To achieve the long-term operation mechanism of "green and efficient, low-carbon cycle, intelligent ecology" of the ecosystem, to ensure the sustainable and stable operation of the treatment system, and the ecological economic value is high.
Sustainable development of people and water resources: taking Karez systems in Xinjiang as an example
Authors: Li Hengyu
Published: December 2024

Xinjiang is situated in the arid inland region of northwest China, belonging to the inland river basin. The replenishment of runoff sources mainly includes precipitation, ice and snow, and groundwater. Precipitation is primarily concentrated in the alpine glacier permafrost zone and the grassland forest belt, while the plain oasis belt and the downstream desert belt receive scant rainfall. The area is characterized by high evaporation and transpiration rates, leading to the local population facing issues of aridity and water scarcity. The Karez system, an ancient water conservancy facility created by the people of Xinjiang in ancient times based on local natural conditions and hydrogeological characteristics, is a very old type of horizontal water-collecting structure for the development and utilization of groundwater. It is suitable for the foothills and the edges of alluvial fans, mainly intercepting groundwater for irrigation and domestic water use, and is widely distributed in the Turpan area of Xinjiang, China. The emergence of the Karez system has formed a unique ecosystem, nurturing the oasis of the Tuha Basin and achieving a balance between humans and water. Regrettably, in recent years, there has been a sharp decline in both the number and water volume of Karez systems, unsettling the equilibrium of the human-water relationship. This paper will delve into the characteristics of water resources in Xinjiang, examine the influence of Karez systems on the water cycle and its utilization, trace the developmental trajectory of Karez systems, and identify the factors contributing to the disruption of the human-water equilibrium. It will offer strategies and future perspectives aimed at achieving sustainable development between human activities and water resources.

The sorting of a group of battery cells with great consistency is critial for the safe and durable operation of battery pack. The conventional methods of battery sorting is based on the linear potential sweep methods, which are complicated and coarse. In this manuscript, the electrochemical impedance spectroscopy was used to determine the kinetic process and electrochemical reactions on the electrodes. There are 41 lithium iron phosphate battery cells(15 Ah) were investigated, and an equivalent circuit was developed to fitted the measure EIS spectrum. The dispersion of the fitting parameters and their variations with SOC were discussed, in which solution resistance RH, constant phase elements (CPEWarburg-Y0 and CPEct-N) at 100% SOC to identify and selected a group of cells with great consistency. The results showed that the sorted battery bells exhibit great consistency as compared the whole sample group. This manuscript demonstrated a non-destructive and effective method for battery sorting, which are instructive for the field of power battery and energy storage battery.
First principles study on the effect of nitrogen doping on the formation energy of substitutional tin in germanium
Authors: Zhou Zihang , Huang Wenqi , Jia Mengjiang
Published: December 2024

In integrated circuits, germanium (Ge) is the core material. Because of Ge's indirect bandgap structure, its ability to produce light efficiently is relatively low. Adding tin (Sn) to germanium can turn it into a material with a direct bandgap, potentially making it a light source for silicon-based photonic interconnect chips. However, obtaining high-quality single crystals of GeSn with a high concentration of Sn is difficult. Experiments show that adding nitrogen (N) can increase the concentration of Sn. This study used first-principles calculations based on density functional theory to explore how adding N affects the formation of substitutional Sn in GeSn alloys. The results indicate that the presence of N changes the electron density around the Ge-Sn bond, which involves the formation energy of substitutional Sn.

Authors: Wang Nan , Wang Jian
Published: December 2024

In this paper, a Dirac operator with formal perturbation is studied. We study the decomposition formula of the Dirac operator squared, and get the generalized Lichnerowicz formula. According to the relation between the noncommutative remainder of a formal Dirac operator and the trace of the Dirac operator, the noncommutative remainder of a formal Dirac operator can be obtained by directly calculating the trace of the endomorphism.
