Published: February 2025

Urban livability is becoming an increasingly significant concept in the field of urban planning and design, especially in rapidly urbanizing mid-sized cities of the Global South, where unplanned growth raises concerns about the living condition of city dwellers. With a focus on Khulna City, Bangladesh, this study aims to improve the understanding of how subjective perceptions and objective assessments of urban livability can coexist and foster the effective planning and design of urban environments, in line with broader planning principles. By integrating local community input with expert evaluations and socio-technical analysis at the fine geographic granularity of urban districts, this study reveals a strong alignment between people’s lived experiences and empirical geographic data, but also significant discrepancies. It highlights the importance of inclusive urban planning that considers both human experiences and environmental factors, stressing the need for flexible planning tools that reflect the unique social and cultural contexts of mid-sized cities in addition to objective assessments. The findings underscore the importance of comprehending the factors that influence urban livability for promoting sustainable urban growth and adopting practical land-use plans. Moreover, this study offers valuable guidance for urban planners and policymakers in designing inclusive, accessible, and environmentally sustainable cities, tailored to the socio-economic realities of fast-growing urban areas.

Published: February 2025

The provision of potable water or water with physical, chemical, and microbiological characteristics suitable for consumption is essential for human survival. However, numerous communities in the coastal areas of Colombia still lack access to clean and safe water sources. To address this challenge in many communities, desalination emerges as a promising solution. In this regard, this article focuses on the evaluation and proposal of an integrated simulation model for solar-powered water desalination in coastal communities, with particular attention to water quality aspects, as well as potential impacts on health and the environment. To carry out a comprehensive assessment, the intention is to design a simulation model using tools such as Homer Pro, IMSdesign, and MATLAB, leveraging data on living conditions and water quality in La Guajira, as well as publicly available information on the best desalination practices in coastal communities and following current Colombian regulations within the framework of health and environmental care. This model will allow for a detailed analysis of key factors and impacts in the implementation of solar-powered desalination systems, considering the conditions of the case study in Manaure, La Guajira, Colombia. Through this design, it facilitates the understanding of technical and operational aspects, as well as exploring efficient energy solutions through the integration of renewable sources, with the purpose of mitigating the challenges associated with high energy consumption and reducing both costs and the environmental and human health impact inherent in these desalination processes.

Published: February 2025

The mobile catenary is installed in the railway loading and unloading line, which could significantly increase the railway freight volume, provide a practical and efficient alternative to the traditional mobile catenary, and greatly improve the sustainability of electrified railroad freight transport. The increase in freight volume also leads to greater traction load and a more complex electromagnetic environment. To study whether the electromagnetic environment when the mobile catenary works meets the power frequency electromagnetic field exposure limit stipulated by the International Commission on Non-Ionizing Radiation Protection, this paper performed an experiment on the sunken mobile catenary. The results showed that the maximum magnetic induction intensity near the ground is 0.03 mT, and the peak electric field intensity on the ground is 1.1 KV/m. The finite element software is adopted to establish the pantograph–catenary model and mobile catenary model according to Principles of Electric Field Calculation and Finite Element Theory, and the space electric field is numerically simulated to study the changes in electric field intensity and distribution of electric field in catenary when the catenary arc occurs. The simulated results are basically consistent with the experimental results, to verify the reliability of the simulation model, which could effectively solve the difficulty and high cost of the experiment. The conclusion proves that the equipment meets the regulations and it highlights the potential, which provides a cost-effective and scalable solution for the electromagnetic environment when the mobile catenary works.

Published: February 2025

Understanding the correlation between soil pollution, environmental indices, humic substances, and soil biota diversity is critical for assessing ecological health, particularly in areas with prolonged contamination. In this study, 90 soil samples were collected from ten locations in El-Mahla El-Kobra area, Egypt, affected by industrial pollution and unsustainable agricultural practices. Significant variations in organic matter, humic substances, microbial biomass carbon, and microbial populations were observed. Heavy metal contamination was highest in site S3, with a contamination degree (CD) of 29.45 and a pollution load index (PLI) of 1.67. Self-organizing maps showed the possible need for targeted remediation to mitigate ecological risk. Biodiversity analysis identified Oribatida as the dominant species, with shifts in diversity indices indicating species adaptation to pollution levels. Positive correlations between soil contamination (CD, PLI) and both Shannon–Wiener and Simpson indices, alongside negative correlations between MCD, PLI, and the Berger–Parker dominance index, suggest a complex shift toward species dominance in polluted environments. The findings highlight the complex interplay between soil contamination and biodiversity, offering critical insights for ecological risk assessment and sustainable soil management in contaminated regions.
A Muti-Scenario Prediction and Spatiotemporal Analysis of the LUCC and Carbon Storage Response: A Case Study of the Central Shanxi Urban Agglomeration
Authors: Zhu Yasi , Quan Bin
Published: February 2025

Land use and cover change (LUCC) profoundly impacts the carbon cycle and carbon storage. Under the goal of “carbon neutrality”, studying the mechanisms linking LUCC with terrestrial ecosystem carbon storage is of significant importance for ecological protection and regional development. Using the central Shanxi urban agglomeration as a case study, this research employs various quantitative models based on land cover data to analyze changes in LUCC and carbon storage from 2000 to 2035. The study scientifically explores the impact of the spatial and temporal distribution characteristics of LUCC on carbon storage. The study indicates the following: (1) Over the past 20 years, the land types in the central Shanxi urban agglomeration are primarily grassland, cropland, and forest land. The two primary land transformations are the conversion of cropland to grassland and the conversion of grassland to cropland and forest land; (2) The carbon storage in the study area has shown a declining trend over the past two decades. Spatially, this decline exhibits a “two mountains and one valley” distribution pattern influenced by land use types. The reduction of grassland and cropland is the primary reason for the decline in carbon storage; (3) By 2035, under three different scenarios, carbon storage is projected to decrease compared to 2020. Among these, the scenario focused on cropland protection (CP) shows the least decline, while the naturally developing scenario (ND) shows the most significant decline. The research demonstrates that under scenarios of cropland protection and ecological conservation, strategies such as environmental restoration, development of unused land, and reclamation of built-up land for greening significantly enhance regional carbon storage and improve carbon sequestration capacity.

Published: February 2025

Coloration patterns in polyclad flatworms of the Pseudocerotidae family are crucial for taxonomic identifications, often serving as key diagnostic character. In this study, we document two pseudocerotid species from the Mexican Pacific exhibiting remarkably similar coloration patterns yet belonging to distinct genera. Through detailed morphological analysis of both external and internal characters, we describe a new species, Pseudobiceros deliae sp. nov. Coria, Bolaños and Quiroga, and report Pseudoceros josei as a new record for Baja California Sur, Revillagigedo Archipelago and Guerrero. Additionally, we provide 28S ribosomal DNA sequences to support future research efforts. Our findings demonstrate that species identification cannot rely solely on distinctive coloration patterns but rather requires a combination of traits, including other external morphological characteristics such as the number of male gonopores, the type of pharynx and the shape of pseudotentacles. Furthermore, we propose that Pseudoceros bicuti is a junior synonym of Pseudoceros josei.

Authors: Fkirin M. A. , Gowaly Zeinab M. , Elsheikh Emad A.
Published: February 2025

The demand for efficient renewable energy solutions has spurred the development of advanced maximum power point tracking (MPPT) algorithms for photovoltaic (PV) systems, especially under variable atmospheric conditions. This study proposes a dynamic MPPT controller utilizing a combination of Long Short-Term Memory (LSTM)-based Artificial Neural Networks (ANNs) and Fuzzy Logic Control (FLC) to optimize power extraction in solar energy systems across diverse irradiance and temperature conditions. The study focuses on designing and implementing these two dynamic MPPT algorithms, LSTM-ANN and LSTM-FLC, to effectively manage the inherent variability in solar energy generation due to fluctuating atmospheric conditions, ensuring that the PV system consistently operates at its optimal power point. The proposed controllers are evaluated and compared to LSTM–Proportional Integral (PI) and traditional MPPT methods, including ANNs, Fuzzy Logic, and hybrid ANN–Fuzzy. The performance metrics used in the evaluation include tracking efficiency, response time, and system stability. The simulation results with real-time data demonstrate that the LSTM-optimized controllers significantly outperform conventional methods, particularly in adapting to sudden changes in irradiance and temperature.

Published: February 2025

Rice is the main source of cadmium (Cd) and arsenic (As) in Chinese diet. The formulation of targeted agronomic interventions for mitigating Cd and As bioaccumulation in rice grains constitutes a critical pathway toward ensuring food safety and public health security. Foliar spraying technology with ionic liquids, effectively reduces Cd/As content in rice. In this study, an ionic liquid of amino acids ([Glu][H2PO4]) as a foliar conditioner was applied to two varieties of rice (X24 and Z35) to explore the mechanism of reducing the accumulation of Cd/As in rice. The results showed that [Glu][H2PO4] reduced Cd/As levels by up to 58.57% and 44.09%, respectively. [Glu][H2PO4] reduced the transfer factor from the root system to flag leaves, nodes, and other organs, thus reducing the Cd/As content in them. [Glu][H2PO4] promoted amino acid synthesis in seeds, increased Ca2+ level, increased OsGLR3.1–3.5 expression, and decreased OsLsi1–3 expression in flag leaves, thereby Cd/As was inhibited from being absorbed and transported by rice. The results demonstrated that the foliar application of [Glu][H2PO4] significantly mitigated the accumulation of Cd/As in rice. This study introduces a novel and effective strategy for reducing Cd/As accumulation in rice, hoping to enhance the safety and quality of rice crops.
Black Hole Thermodynamics and Generalised Non-Extensive Entropy
Authors: Elizalde Emilio , Nojiri Shin’ichi , Odintsov Sergei D.
Published: February 2025

The first part of this work provides a review of recent research on generalised entropies and their origin, as well as its application to black hole thermodynamics. To start, it is shown that the Hawking temperature and the Bekenstein–Hawking entropy are, respectively, the only possible thermodynamical temperature and entropy of the Schwarzschild black hole. Moreover, it is investigated if the other known generalised entropies, which include Rényi’s entropy, Tsallis entropy, and the four- and five-parameter generalised entropies, could correctly yield the Hawking temperature and the ADM mass. The possibility that generalised entropies could describe hairy black hole thermodynamics is also considered, both for the Reissner–Nordström black hole and for Einstein’s gravity coupled with two scalar fields. Two possibilities are investigated, namely, the case when the ADM mass does not yield the Bekenstein–Hawking entropy, and the case in which the effective mass expressing the energy inside the horizon does not yield the Hawking temperature. For the model with two scalar fields, the radii of the photon sphere and of the black hole shadow are calculated, which gives constraints on the BH parameters. These constraints are seen to be consistent, provided that the black hole is of the Schwarzschild type. Subsequently, the origin of the generalised entropies is investigated, by using their microscopic particle descriptions in the frameworks of a microcanonical ensemble and canonical ensemble, respectively. Finally, the McLaughlin expansion for the generalised entropies is used to derive, in each case, the microscopic interpretation of the generalised entropies, via the canonical and the grand canonical ensembles.

Published: February 2025

Yersinia pseudotuberculosis causes yersiniosis in a wide range of mammalian and avian taxa worldwide. This review aims to provide an overview of the current literature on yersiniosis in non-domesticated mammals and birds in captivity. Data on the prevalence of Y. pseudotuberculosis in captive populations are scarce. Transmission is primarily via the fecal–oral route, with wild rodents and birds as primary reservoirs. Predisposing factors to yersiniosis include young age, inclement weather, stress, and genetic factors. Symptoms are often non-specific, with sudden death occurring frequently, particularly in avian species. Gross pathological examination typically reveals multiple white-yellow foci in visceral organs, while histopathology demonstrates necrosis with central bacterial colonies. Ante-mortem diagnosis can be challenging as bacterial culture and isolation from fecal samples are often hindered by intermittent excretion and competition with other gastrointestinal flora. Although killed and subunit vaccine formulations have demonstrated limited protective efficacy, live attenuated strains may hold greater promise for inducing more robust and durable immunity. Y. pseudotuberculosis remains a significant threat to animal health, highlighting the need for faster and more reliable diagnostic techniques and the development of more effective treatment and prophylactic strategies.

This manuscript explores the removal of eosin yellow dye, a toxic color substance contributing to water pollution, from aqueous solutions. For this purpose, iron-zirconia binary oxide (Fe2O3-ZrO2) was functionalized with eugenol oil, a natural phenolic aromatic compound extracted from the clove plant. The functional groups developed in the binary oxide were confirmed by Fourier transform infrared spectroscopy (FT-IR), and its crystal structure was determined via X-ray diffraction (XRD). The grain size analyzed by the XRD pattern was found to be 45 nanometers. The morphological analysis revealed nanoparticles of quasi-spherical type with a size ranging from 4 to 5 nanometers. The consistency between SEAD and XRD further confirmed that the material formed was iron-zirconia binary oxide. The obtained material, which was insoluble in water, was used as an adsorbent. Through the adsorption study of eosin yellow dye, the maximum monolayer adsorption capacity of approximately 91.0 mg/g at 27 °C and pH = 7.0 for the functionalized adsorbent was determined. The process was exothermic, feasible, and spontaneous. At a dose of 1.0 g/L, the adsorbent was responsible for removing more than 90% of eosin yellow with 10–70 mg/L initial concentration, while about 56% removal was achieved at a higher concentration of 150 mg/L at 27 °C and pH = 7.0. These results highlight the potential of functionalized Fe2O3-ZrO2 as an effective adsorbent for water purification applications.

This study assessed soil erosion intensity and soil properties across the Crveni Potok catchment in Serbia, a region of diverse morphology, geology, pedology, and vegetation. Soil samples were collected using a regular grid approach to identify the underlying factors contributing to erosion and the most vulnerable areas. Based on 137Cs activities and the profile distribution (PD) model, severe erosion (>10 t ha−1 y−1) was predicted at nearly 60% of the studied locations. The highest mean erosion rates were detected for the lowest altitude range (300–450 m), Rendzic Leptosol soil, and grass-covered areas. A significant negative correlation was found between the erosion rates, soil organic matter, and indicators of soil structural stability (OC/clay ratio and St), indicating that the PD model successfully identifies vulnerable sites. The PD and RUSLE (revised universal soil loss equation) models provide relatively similar mean erosion rates (14.7 t ha⁻1 y⁻1 vs. 12.7 t ha⁻1 y⁻1) but significantly different median values (13.1 t ha−1 y−1 vs. 5.5 t ha−1 y−1). The model comparison revealed a positive trend. The observed inconsistencies were interpreted by the models’ spatiotemporal frameworks and RUSLE’s sensitivity to input data quality. Land use stands out as a significant factor modifying the variance of erosion rate, highlighting the importance of land management practices in mitigating erosion.

Published: February 2025

The cooling system plays an essential role in regulating the temperature of hybrid vehicle engines. With the contemporary surge in the number of hybrid vehicles, the cooling system’s performance is vital for the safe and stable operation of these cars. The radiator, as the core component of the cooling system, has become central to enhancing thermal efficiency through performance optimization. Improvements to existing radiators are especially important in order to meet increasing performance demands. This paper firstly outlines the development of radiator technology for hybrid vehicles both domestically and internationally; it then analyzes the tube and belt radiator, and selects a louvered finned radiator with highly efficient heat dissipation performance as the object of research. It then carries out the detailed design and assessment of the radiator, formulates an accurate design scheme, and creates a three-dimensional model of the radiator and its main parts using the CATIA V5 software. Finally, the simulation and analysis Fluent software (ANSYS 2023 R1) is used to carry out a comparative analysis of the designed radiator and its important parts. The study focuses on how fin angle, inlet and outlet positioning, radiator orientation, and fan speed affect thermal performance. The findings indicate that a 26° fin angle, a same-side inlet and outlet layout, correct radiator orientation, and higher fan speeds enhance cooling efficiency. These optimizations improve radiator performance, ensuring efficient cooling under various operating conditions.

The Development and Characteristics of an In-Wheel Assembly Using a Variable Speed-Reducing Device
Authors: Shin Kyeongho , Ko Kyoungjin , Hwang Junha
Published: February 2025

This study proposes an in-wheel assembly with a variable speed-reduction device designed to maximize torque and vehicle speed, enabling high-performance vehicle-level driving characteristics in front-engine, rear-wheel drive (FR), internal combustion engine (ICE) vehicles, where conventional EV motors cannot facilitate e-4WD. The proposed system integrates a motor and speed reducer within the wheel while avoiding interference from braking, steering, and suspension components. Through various innovative approaches, concepts for an integrated wheel-bearing planetary reducer and a variable speed planetary reducer were derived. The developed system achieved twice the maximum torque and a 35% increase in top speed compared to previously developed in-wheel systems, all without altering the front hard points. Multi-body dynamic analysis and component testing revealed wheel lock-up issues during reverse driving, and instability in the one-way clutch at high speeds. To address these issues, the power transmission structure was improved, and the type of one-way clutch was modified. Additionally, deficiencies in lubrication supply to the friction surface of the one-way clutch were identified through flow analysis and visualization tests, leading to design improvements. The findings of this study demonstrate that even in in-wheel systems where the application of large and complex transmission devices is challenging, it is possible to simultaneously enhance both maximum torque and top vehicle speed to achieve high-performance vehicle-level driving dynamics. Consequently, implementing an in-wheel e-4WD system in ICE FR vehicles is expected to improve fuel efficiency, achieve high-performance vehicle capabilities, and enhance market competitiveness.
Are We Testing Vehicles the Right Way? Challenges of Electrified and Connected Vehicles for Standard Drive Cycles and On-Road Testing
Authors: Grano Elia , Villani Manfredi , de Carvalho Pinheiro Henrique , Carello Massimiliana
Published: February 2025

Standard driving cycles have been the method of choice for testing vehicle performance for decades, both in research and at the regulatory level. These methodologies offer the significant advantage of test reproducibility, allowing for consistent comparisons between vehicles. However, their inability to reflect real-world driving conditions has become increasingly evident. This issue was first exacerbated by the advent of hybrid and plug-in hybrid vehicles, which introduced new complexities in powertrain operation. Legislators attempted to adapt testing procedures to account for electric energy usage in emissions assessments, but these efforts have largely failed to address the technical challenges posed by modern vehicles. As a result, the gap between real-world fuel consumption and type-approval values has continued to grow. The introduction of ADAS technologies has further widened this discrepancy, as standard driving cycles are no longer capable of accurately representing modern vehicle performance. In light of these challenges, this paper critically evaluates the limitations of standard drive cycles and on-road testing procedures, explores how hybrid and connected vehicles further complicate performance assessment, and proposes directions for improving these methodologies.

Published: February 2025

Heavy goods transportation is responsible for around 27% of CO2 emissions from road transport in the EU and for 5% of total CO2 emissions in the EU. The decarbonization of long-distance transport in particular remains a major challenge. The combination of battery electric trucks (BETs) with on-route high-power charging (HPC) offers a promising solution. Planning and setting up the required infrastructure is a critical success factor here. We propose a methodology to evaluate the charging infrastructure needed to support the large-scale introduction of heavy-duty BETs in Germany, considering different levels of electrification, taking the European driving and rest time regulations into account. Our analysis employs MATSim, an activity-based multi-agent transport simulation, to assess potential bottlenecks in the charging infrastructure and to simulate the demand-based distribution of charging stations. The MATSim simulation is combined with an extensive pre-processing of transport-related data and a suitable post-processing. This approach allows for a detailed examination of the required charging infrastructure, considering the impacts of depot charging solutions and the dynamic nature of truck movements and charging needs. The results indicate a significant need to augment HPC with substantial low power overnight charging facilities and highlight the importance of strategic infrastructure development to accommodate the growing demand for chargers for BETs. By simulating various scenarios of electrification, we demonstrate the critical role of demand-oriented infrastructure planning in reducing emissions from the road freight sector until 2030. This study contributes to the ongoing discourse on sustainable transportation, offering insights into the infrastructure requirements and planning challenges associated with the transition to battery electric heavy-duty vehicles.

Published: February 2025

This study extends beyond conventional Battery Thermal Management System (BTMS) research by conducting a Life Cycle Analysis comparing the environmental impacts of two technologies: a traditional active cold plate system and an innovative passive Loop Heat Pipe (LHP) system. While active cold plate BTMS requires continuous energy input during operation and charging, leading to significant energy consumption and emissions, the passive LHP BTMS operates without external power or moving parts, substantially reducing the climate change impact. This analysis considered two materials for LHP construction: copper and stainless steel. The results demonstrated that the LHP design achieved a 9.9 kg reduction in overall BTMS mass compared to the cold plate system. The implementation of stainless steel effectively addressed the high resource consumption associated with copper while reducing environmental impact by over 50% across most impact categories, compared to the cold plate BTMS. The passive operation of the LHP system leads to substantially lower energy usage and emissions during the use phase compared to the active cold plate. These findings highlight the potential of passive LHP technology to enhance the environmental sustainability of Battery Thermal Management Systems while maintaining effective thermal performance.

Following up on my research into youth leisure published in the last issue of Lithuanian Ethnology, in this article I compare my personal field research carried out from 1988 to 2012 and publications in the press from 1926 to 1939, analysing the calendar feasts celebrated by Lithuanians in the Vilnius region. Based on the same methodology, the study revealed that the value of leisure and festivals as a source of ethnology differs in the periodical press. While descriptions of leisure in the press tolerate traditional forms, the descriptions of festivals promote only modern customs in which one cannot trace the specificity of the customs of the Vilnius region. Although the periodical press declared its desire to preserve old folk traditions, it was a reliable tool in shaping the modern calendar.

Authors: Ramos Danilo , Ribeiro Gabriella Luebke
Published: February 2025

Em cursos de graduação em música no Brasil, estudantes de piano costumam apresentar dificuldades no estudo de harmonia. Segundo a Teoria Geral da Expertise, de Anders Ericsson, o domínio de qualquer habilidade depende da eficácia das representações mentais, estruturas mnemônicas que auxiliam na rápida recuperação de informações armazenadas na memória de longo prazo. O objetivo desta pesquisa foi o de investigar o papel das representações mentais de um estudante de piano na resolução de um teste envolvendo seis questões de harmonia, todas retiradas de uma prova de um vestibular de música. O estudante foi submetido à aplicação de um protocolo think-aloud durante a realização do teste. Sua fala foi transcrita e submetida a uma análise de conteúdo. Os resultados mostraram que o estudante não acertou nenhuma das questões. Acredita-se que isto tenha ocorrido por conta de falhas em suas representações mentais durante a resolução do teste.

Published: February 2025

O objetivo desta pesquisa foi investigar as representações mentais elaboradas por um pianista expert na execução de diferentes levadas rítmicas ao piano. Um estudo de caso foi conduzido com a aplicação do protocolo think-aloud. Em duas sessões de observação, o pianista elaborou o arranjo da música “Capim” de Djavan e, em seguida, alterou o arranjo inicial para outras levadas rítmicas brasileiras. As verbalizações do pianista foram submetidas a uma análise de conteúdo e categorizadas de acordo com padrões de informações característicos de gêneros musicais e pianistas brasileiros de referência. Os resultados indicam que a elaboração imediata dos arranjos esteve relacionada com a capacidade de o expert organizar representações mentais de forma coerente com cada estilo musical vivenciado. Conclui-se que as representações mentais do pianista se desenvolveram por meio de treinamento especializado de longo prazo, o que corrobora os pressupostos da Teoria Geral da Expertise de Anders Ericsson.

Published: February 2025

Este artigo consiste em uma investigação sobre a corporeidade na prática pianística com base em teorias corporificadas e atuacionistas da cognição. Foi realizada pesquisa exploratória (Gil, 2008; Gasque, 2007) a partir de uma revisão de literatura publicada no Brasil entre 2013 e 2023 (Vieira et al., 2015; Cruz e Ferreira, 2023), da qual encontram-se destacados estudos do corpo em movimento na prática pianística. O reconhecimento de categorias de abordagens investigativas direcionou a um afunilamento metodológico em aproximações interdisciplinares com os campos de cognição musical corporificada e enativista. Tais aproximações permitem compreender uma dimensão sensório-motora da técnica pianística enquanto ação intencional integrada à percepção das próprias ações, ressaltando aspectos sensoriais do movimento relacionados a características de cada prática musical contextualizada em um ambiente sociocultural.

China stands as the world’s largest producer of both conventional and organic tea. However, the economic and environmental performances of labor input intensity on tea cultivation processes remain understudied at present. For Chinese tea varieties, highly specific distribution of major producing regions always led to variations of tea production under conventional management (CM) and organic management (OM) conditions. Therefore, this study focused on the production of Pu’er tea and thus chose the Yunnan province as the study region, which is the largest Pu’er tea-growing province in China. The study compared the economic and environmental performances between organic and conventional Pu’er tea plantations under different labor intensities by a joint analysis based on economic analysis, emergy evaluation, and environmental footprints. The findings revealed that compared with CM, OM reduced costs by 9.06% (
P
< 0.05) and enhanced the ratio of income to cost by 33.00% (
P
< 0.05). The emergy sustainability index (ESI) of OM was 33.58% (
P
< 0.05) higher than that of CM. The environmental footprint index (EFI) per unit area and per unit economic output for OM decreased by 17.31% (
P
< 0.05) and 37.77% (
P
< 0.05), respectively, compared to CM. The CM and OM had better economic and ecological benefits when the labor input intensity was 3 to 6 and 8 to 10 persons/hm
2
, respectively. This study provided a novel perspective on understanding the interaction between labor allocation and green income growth in tea production. The findings of this study offered solid scientific evidence and decision support for the green transformation of Chinese tea industry.

Харківський національний педагогічний університет імені Г. С. Сковороди визначає 220 років з дня заснування. Як найстаріший вищий педагогічний заклад має нагоду перегорнути сторінки власної історії. Серед відомих досягнень освітнього закладу була ізалишається підготовка учителів, які своєю працею роблять славу Альма-Матері. Серед унікальних випускників (1955 р.) маємо назвати доктора технічних наук, професора, академіка-секретаря відділення атомної фізики і енергетики НАН України, Почесного громадянина м. Харкова Івана Матвійовича Неклюдова. Його науково-професійний шлях знайшов гідне висвітлення в численних монографіях, науково-публіцистичних статтях. На наш погляд, заслуговує на увагу звернення до біографічних даних, пов’язаних з навчанням Івана Матвійовича у стінах педагогічного закладу, підкріплення ролі його постаті для виховання майбутніх учителів. Підкреслено, що І. М. Н еклюдов — один із найвидатніших фізиків світового рівня і один із тих скромних харків’ян, який в науці досяг найвищих вершин. Наведено вислів О. Зеленської, що «честь науковому таланту І. М. Н еклюдова робить те, що він отримав вищу освіту в педагогічному інституті, а не в університеті імені В. К аразіна, де вже тоді була «всесвітньо відома система навчання з унікальною науково-освітньою інфраструктурою, аналогів якої не існувало в освіті». Зазначено, що хоч у в педагогічному інституті викладалися фізико-математичні дисципліни на високому рівні, але студентам доводилося докладати більше зусиль, наполегливості, щоб виявити і розвинути здібності і нахили у науці. Матеріалом для публікації стали спогади дружини, колег, привітання академіка з нагоди ювілейних дат, нагородження орденами, медалями тощо, монографії, ювілейні видання, нариси з історії розвитку фізики. У статті використано матеріали публікацій А. В. Таньшиніної і О. Зеленської та інших. Мета статті: систематизувати відомості про Івана Матвійовича Неклюдова як студента ХНПУ імені Г. С. Сковороди, підкреслити роль його постаті для формування майбутніх учителів, зокрема вчителів- фізиків; показати на його прикладі шляхи розвитку і реалізації творчих, інтелектуальних потенційних ресурсів.
