An Improved Differential Evolution for Parameter Identification of Photovoltaic Models
Authors: Yuan Shufu , Ji Yuzhang , Chen Yongxu , Liu Xin , Zhang Weijun
Published: September 2023

Photovoltaic (PV) systems are crucial for converting solar energy into electricity. Optimization, control, and simulation for PV systems are important for effectively harnessing solar energy. The exactitude of associated model parameters is an important influencing factor in the performance of PV systems. However, PV model parameter extraction is challenging due to parameter variability resulting from the change in different environmental conditions and equipment factors. Existing parameter identification approaches usually struggle to calculate precise solutions. For this reason, this paper presents an improved differential evolution algorithm, which integrates a collaboration mechanism of dual mutation strategies and an orientation guidance mechanism, called DODE. This collaboration mechanism adaptively assigns mutation strategies to different individuals at different stages to balance exploration and exploitation capabilities. Moreover, an orientation guidance mechanism is proposed to use the information of the movement direction of the population centroid to guide the evolution of elite individuals, preventing them from being trapped in local optima and guiding the population towards a local search. To assess the effectiveness of DODE, comparison experiments were conducted on six different PV models, i.e., the single, double, and triple diode models, and three other commercial PV modules, against ten other excellent meta-heuristic algorithms. For these models, the proposed DODE outperformed other algorithms, with the separate optimal root mean square error values of 9.86021877891317 × 10−4, 9.82484851784979 × 10−4, 9.82484851784993 × 10−4, 2.42507486809489 × 10−3, 1.72981370994064 × 10−3, and 1.66006031250846 × 10−2. Additionally, results obtained from statistical analysis confirm the remarkable competitive superiorities of DODE on convergence rate, stability, and reliability compared with other methods for PV model parameter identification.

Authors: Peng Hao , Jin Afang , Zhang Shuzhi , Zheng Bin
Published: September 2023

This paper introduces a kind of double-row reed–nylon net combined sand barrier. Using the computational fluid dynamics (CFD) method and the Euler–Euler double-fluid model, the new sand fences’ windproof effect and airflow features are simulated under different porosities and spacings, and the optimal configuration parameters are selected. The new sand fence has better windproof performance and practical significance than double-row reed and double-row nylon net fences. The new sand fences with a porosity of 0.3–0.4 and spacing of 28 H provide a longer protection range and a better wind protection effect. Considering the serious sand damage in China’s Taklamakan Desert, the new fences’ impact on sand buildup is examined. The combined sand fences have powerful sand blocking and accumulation effects, even though there is only a small quantity of sand accumulation on the leeward side of the second row. The sand particles primarily settle between sand fences in the center and rear areas. The combination of sand fences made of different materials combines the advantages of both, improves the construction efficiency and service life, and provides a more economical and efficient sand barrier arrangement for the arrangement of wind and sand-blocking facilities around railroads and highways in desert areas.
Research on the Whole Life Cycle of a Furniture Design and Development System Based on Sustainable Design Theory
Authors: Li Yijie , Xiong Xingfu , Qu Min
Published: September 2023

With the development of society, the negative impact of furniture waste on the environment has become increasingly prominent. Therefore, it has become essential to integrate sustainable design principles into furniture manufacturing. This integration can significantly extend the service life of furniture products and reduce the adverse impact on the environment. To achieve this goal, it is necessary to actively conduct market research and an in-depth understanding of users’ needs for sustainable furniture design. Among them, applying the AHP-QFD-AD method to develop a comprehensive design evaluation model is a practical way. This model can translate user requirements into explicit functional requirements and further refine them into specific design parameters. Accurately reflecting user needs in product design greatly improves the accuracy of design evaluation, thereby reducing environmental impact throughout the product life cycle. By implementing this integrated model, we can move furniture products in a sustainable direction. In addition, this method can also enhance the connection between the user and the product, extend the service life of the product, and reduce the waste of furniture. Using sustainable shelving development as an example, we validate the proposed method model. This study reduces the harm of discarded furniture to the environment, providing some support for sustainable furniture design practices.

Authors: Baykal Elif , Divrik Bahar
Published: September 2023

Without a doubt, encouraging the behavior of employees in relation to sustainability is one of the most effective tactics that organizations can use to attain their sustainability goals. It is critical that employees take part in sustainability projects in order for organizations to be successful. In this study, we assumed that organizations supported by responsible employees will be more likely to engage in sustainability-driven projects that affect their long-term viability and the interests of their stakeholders, and that green human resources management will be an encouraging factor. The purpose of this study was to investigate the involvement of employees in sustainability-driven projects within organizations, as well as the potential influence of such involvement on the performance of projects in emerging economies such as Turkey, where individual sensitivity to sustainability is lacking. With this goal in mind, we conducted a qualitative investigation on ten different employees from various corporate enterprises who were authorized to participate in sustainability-driven projects in their workplaces. Our results revealed that in the Turkish business environment, employees have still not reached the required level of maturity regarding sustainability issues in order to be initiators of sustainability projects. This study is the first to investigate the role of employees in sustainability-driven projects within the Turkish market.

Published: September 2023

The agricultural development of reclaimed coastal areas in Jiangsu Province is significantly hindered by high soil salinity and an inadequate irrigation and drainage infrastructure. Optimizing the layout of subsurface drainage systems has been identified as an effective means of reducing soil salinity, with the proper designation of engineering parameters being crucial. This study applied 12 treatments (T1–T12) consisting of four different spacings of subsurface drainage pipes (6 m, 11 m, 15 m, and no subsurface drainage pipes) and three observation wells at varying distances from the drainage outlet (5 m, 25 m, and 45 m). Results showed that all three subsurface pipe spacing treatments significantly reduced soil salinity compared to natural drainage, with a smaller subsurface pipe spacing treatment leading to better salt-reducing effects. The farther the distance from the measuring point to the drain, the higher the salinity. As the burial depth of the outlet decreased and spacing between the subsurface drainage pipes decreased, the salinization rate of the 0–60 cm soil layer was higher, while the salt accumulation in the 60–80 cm soil layer was more severe. Therefore, a subsurface drainage pipe spacing of 6 m and an outlet burial depth of 40 cm are recommended as more suitable choices to effectively control salt concentration in the soil. The research aimed to provide scientific reference data and technical support for the optimized design of subsurface drainage engineering parameters while promoting efficient desalination of saline-alkali areas worldwide.
New Insights into the Layering Process of Urban Environment and Private Garden Transformations: A Case Study on the Bubbling Well Road Area in Early Modern Times, Shanghai
Authors: Chen Zhehua , Xu Qing , Zhou Xiangpin , Yang Yanping
Published: September 2023

The surrounding area of Bubbling Well Road in early modern times, Shanghai, served as an important transportation hub connecting the western and central districts of Shanghai’s International Settlement. It also marked the beginning of a half-century trend of profit-oriented private gardens. The development process from rural outskirts to bustling commercial areas is exemplified by the area of Bubbling Well Road, making it significant for the study of urban transformation in early modern times in Shanghai. In this work, private gardens in the vicinity of Bubbling Well Road are examined as hierarchical elements of urban subdivision using the layering approach of the Historic Urban Landscape. Based on summarizing the trajectory of different types of private gardens under urbanization, typical time nodes were extracted and then horizontally correlated with the process of urbanization to elucidate the hierarchical logic underlying the symbiotic interaction between private gardens and cities. The results show that private gardens have created new hot spots and gathered a lot of popularity for the Jing’an Temple area, prompting this area to gradually evolve from a traditional town to a “backyard garden” of Concession dominated by the entertainment industry. Through the rapid development of the modern entertainment, commerce, and real estate industries, the Jing’an Temple area successfully embraced the trend of developing Concession to the West while achieving transformations in business models and urban style. Finally, with the assistance of the transitional entertainment space, such as profit-oriented gardens, the Jing’an Temple area has successfully undergone a transformation into a modern entertainment industry hub and solidified its commercial status as the “consumption circle” of Shanghai. We systematically investigated the significance of the urban subdivision layer in relation to the temporal changes in the urban environmental structure and the evolution of spatial organization patterns at the macro level; this helps deepen the historical urban landscape approach from an ideological framework level to the practical level.
The Momentum Transfer Mechanism of a Landslide Intruding a Body of Water
Authors: Meng Zhenzhu , Hu Jianyong , Zhang Jinxin , Zhang Lijuan , Yuan Zhenxia
Published: September 2023

Landslide-generated waves occur as a result of the intrusion of landslides such as mud flows and debris flows into bodies of water such as lakes and reservoirs. The objective of this study was to determine how the momentum is transferred from the sliding mass to the body of water on the basis of theoretical analysis and physical model experiments. Considering the viscoplastic idealization of natural landslides, the theoretical model was established based on the momentum and mass conservation of a two-phase flow in a control volume. To close the theoretical equations, slide thickness and velocity passing through the left boundary of the control volume were estimated by lubrication theory, and the interaction forces between the slide phase and water phase, including hydrostatic force and drag force, were given by semiempirical equations fitted with experimental data obtained using the particle image velocimetry (PIV) technique. The near-field velocity fields of both the sliding mass and the body of water, as well as the air–water–slide interfaces, were determined from the experiments. The theoretical model was validated by comparing the theoretical and experimental data of the slide thickness and slide velocity, as well as the momentum variations of the two phases in the control volume.

Dual co-infection with both HSV-1 and HSV-2 is rare, with few cases reported in the literature. In this case report, we describe the successful use of unbiased metagenomic next-generation sequencing (mNGS) as a rapid and alternative method for confirming dual genital herpes co-infection. Our case involves a 74-year-old woman who presented with genital lesions and initially tested positive for both HSV-1 and HSV-2 via the Luminex ARIES HSV 1&2 assay. The entire mNGS process, from nucleic acid extraction to result analysis, was completed in less than 48 h. Using mNGS, we identified mapped reads specific to either HSV-1 or HSV-2 and screened the sequences to rule out mis-genotyping by the Luminex ARIES assay. Notably, the generated sequences can reveal sequence variations within multiple gene regions, demonstrating the potential of mNGS for identifying novel HSV-1 and HSV-2 variants. Our findings suggest that mNGS can serve as a rapid and reliable alternative confirmatory method for dual genital herpes infections, providing valuable information to guide appropriate treatment options for patients. By eliminating the need for prior knowledge of causative agents, mNGS offers an unbiased approach for detecting and characterizing viral co-infections.
Tracking Multiphase Flows through Steep Reservoirs with External Constraint
Authors: Nazeer Mubbashar , Ali Waqas , Hussain Farooq
Published: September 2023

Problem statement: The study offers theoretical formulations for high-viscosity particulate flows in inclined reservoirs, taking into account the presence of homogeneous spheroidal particles of various types to produce discrete two-phase suspensions. Purpose: The primary objective of this analytical and comparative study is to identify the most dependable nanoparticles among hafnium and crystal metals that are suspended in an Eyring–Powell fluid through an inclined channel while being subjected to external magnetic and gravitational forces. Solution methodology: The flow dynamics of multiphase flows are formulated utilizing the stress tensor of the base fluid. The regular perturbation method (RPM) is employed to attain a more closed-form solution. The perturbation method is frequently employed in engineering problems to obtain an approximated solution, even when demonstrating the convergence of the solution is challenging. The rough solution is also validated through a thorough parametric analysis that shows the role of relevant parameters that contribute to the multiphase flow. Results: A concise parametric study is carried out against some of the most pertinent parameters and reveals that additional particles have promising effects on the momentum of each multiphase flow, whereas Eyring–Powell multiphase suspensions lessen in momentum due to strong internal viscous forces. The velocity of fluid and particle phases diminish with Hartmann number M and Froude number Fr. The second-order material constant B and concentration of nanoparticles C boost the motion of the fluid. The velocities of the particulate phase are quicker than the fluid phase. The hafnium particle is more reliable than crystal particles. Solution benchmark: Numerical and graphical findings have also been compared with the existing literature for the limiting case and found to be fully in agreement. Applications: This study’s findings provide a wider understanding of subterranean flows, specifically within the petroleum sector, with a focus on multiphase flows. Originality: The current study represents the authors’ original work and has not been previously submitted or published elsewhere.

O carcinoma hepatocelular constitui uma das neoplasias malignas mais letais e com eficácia terapêutica limitada. Os extratos vegetais, ricos em metabólitos secundários, realizam funções benéficas ao organismo humano, como a redução da inflamação, dor, estresse oxidativo e da neoplasia. Assim, o objetivo deste estudo foi o de realizar a triagem fitoquímica (fenóis e flavonóides) do extrato do fruto de Brosimum gaudichaudii (EBG), avaliar in vitro a sua citotoxicidade (teste do MTT/células NIH/3T3), e suas atividades antioxidante (DPPH e Lipoperoxidação) e antineoplásica (teste do MTT/células HuH7.5). O EBG apresentou 48,02 ± 1,26 mg EAG/g de fenóis totais e 8 ± 0,92 mg EQ/g de flavonoides. No MTT, o EBG, de 100 a 1600 ug/mL, não diferiu do controle negativo, não promovendo citotoxicidade (p>0,05). O EBG, 600 µg/mL, apresentou uma atividade antioxidante de 79.80 ± 0.00% no teste do DPPH e de 88.01 ± 1.74% no teste de lipoperoxidação. Na avaliação anticancerígena em células de hepatocarcinoma, nos tempos de 24, 48 e 72 horas, as concentrações de 1,8, 2,8 e 4,4 ug/mL promoveram 50% de inibição do crescimento celular (GI50%). Como a atividade antineoplásica de um extrato está relacionada a um GI50% < 4,0 ug/ml o EBG se apresenta como um possível fitoterápico a ser utilizado na terapia complementar do hepatocarcinoma.

Pacientes internados em terapia intensiva por diversas vezes fazem uso de uma terapia polimedimencamentosa, onde destintas classes de medicamentos são utilizados simultaneamente de acordo com a condição clínica atual do paciente. O emprego dessa multiterapia desencadeia uma grande chance de ocorência de erros relacionados a medicação. Estíma-se que cerca de 30 a 40% do orçamento que é investido em saúde seja destinado para aquisição de medicamentos, fazendo com que sejam instituídas ferramentas para otimização desse recurso. O objetivo desse estudo foi analizar o impacto farmacoeconômico gerado a partir das intervenções farmacêuticas realizadas nas prescrições dos pacientes internados em terapia intensiva. Trata-se de um estudo observacional, transversal com coorte retrospectivo cujos dados foram coletados entre os meses de junho e julho de 2023 referente aos meses de outubro e novembro de 2022. A coleta de dados foi realizada advinda das prescrições médicas e do acompanhamento farmacoterapêutico diario realizadas nas unidade de terapia intensiva adulto I e II. Os resultados obtidos ao final do estudo demostram um grande impacto econômico gerado pelas intervenções farmacêuticas, foram analisadas 936 prescrições e realizadas 600 intervenções onde obtiveram uma redução de R$ 23.949,99 referentes aos dois meses de estudo. A farmacoeconomia gerada pela atuação do farmacêutico clínico tem sido evidenciada em diversos estudos o que destaca a importância desse profissional na integração da equipe multidisciplinar na UTI. Esse estudo corroborou com evidências anteriores de que a participação do farmacêutico clínico no acompanhamento farmacoterapêutico beira leito fornece valor econômico e garante uma melhor assistencia em ambientes de saúde.
A fundada suspeita em abordagens policiais e na busca pessoal
Authors: Cardoso Alexsander , Vieira Leonardo Rozwalka
Published: September 2023

O presente artigo se propôs a analisar o instituto da fundada suspeita utilizada pelas forças policiais, durante a realização de abordagens seguidas da busca pessoal. Tema de relevante debate jurídico, atualmente ganhou maior destaque em razão de recentes julgados pelo Superior Tribunal de Justiça no que tange aos requisitos mínimos necessários para assegurar a legalidade e os limites da chamada fundada suspeita em abordagens policiais seguidas de busca pessoal. Neste debate, deve-se traçar uma linha divisória entre a abordagem policial e a busca pessoal, a fim de que não sejam tratadas como o mesmo instituto. Desta forma, traz-se a luz o artigo 240, §2º  do Código de Processo Penal Brasileiro, que exige a existência da fundada suspeita para realização da busca pessoal. Tal requisito foi por muitos anos tratado de maneira ampla nas ações policiais, sendo justificado pelas técnicas de tirocínio policial, ensinadas pela doutrina especializada. Ocorre que a expressão fundada suspeita é demasiadamente subjetiva. Qualquer definição pode ser questionada, o que leva a infinitos debates. Desta forma, o objetivo deste artigo é abordar os elementos caracterizadores da fundada suspeita, buscando diferenciá-la do conceito de abordagem policial. Para isso levou-se em conta, diversos julgados trazidos pelos Tribunais Superiores, ensinamentos doutrinários e artigos científicos publicados sobre o tema. No que diz respeito a busca pessoal, podemos afirmar que trata-se de um procedimento investigatório de natureza ainda precária, porém indispensável para o combate à criminalidade e garantia da ordem pública, sendo dotada do “periculum in mora”, uma vez que o caso de sua não realização imediata, implica em possível falha na instrução investigatória e aumento do sentimento de impunidade e crescimento da criminalidade, gerando transtornos a sociedade e ao Estado de Direito.

O acúmulo de liquido na cavidade uterina da égua pós-inseminação ou pós-coito é considerado normal devido à uma reação fisiológica de limpeza desenvolvida pelo animal, afim de eliminar as sujidades e o sêmen, reconhecido pelo organismo como estranho, preparando o útero para a instalação do embrião. Este processo deve ocorrer no período de 24 a 72 horas. Ultrapassando o período fisiológico, este acúmulo de líquidos começa a prejudicar a saúde reprodutiva do animal, levando a uma endometrite, podendo evoluir para uma endometriose degenerativa excluindo o animal da vida reprodutiva. A endometrite é uma das principais causas de infertilidade da égua e pode ter diversas origens. Neste trabalho, objetivou-se relatar algumas causas, diagnósticos e tratamentos da endometrite equina em revisão literária.

Authors: DUTRA DE ANDRADE ROBERTA , Gonçalves Pinheiro Paulo , Cagica Carvalho Luisa
Published: September 2023

Informed by exchange and social capital theories, reasoned action, and psychological contract frameworks, this paper seeks to elucidate the intricate interplay between psychological contracts and their impact on knowledge-sharing motivations within the context of startups. The research adopts a qualitative approach, employing in-depth personal interviews and focus groups, with subsequent content analysis facilitated by NVivo software. Through a comprehensive exploration encompassing startups spanning diverse industries and maturity levels, the investigation draws upon insights from founding partners, directors, and employees. Notably, this study stands apart from the literature primarily examining established enterprises in Anglo-Saxon nations. Conversely, it distinguishes itself by its novel examination of how psychological contracts exert influence on knowledge sharing across individual, intra-organizational, and inter-organizational strata within startups operating in emerging economies, taking into account their distinctive characteristics. The findings shed light on employees' core perceptions of their reciprocal obligations and the organization's corresponding commitments. Moreover, the research unveils the nuanced impact of contextual factors on the cultivation of social bonds, consequently moulding knowledge-sharing dynamics within startups, thereby directly shaping individual and organizational outcomes.

Проводится анализ основных численных, временных и одной из вероятностных характеристик классической одноканальной системы массового обслуживания M/M/1, результаты которого позволяют наряду с частными выводами по каждой анализируемой характеристике получить общесистемную закономерность в виде проявления золотого сечения в прямом или косвенном виде. Получено устойчивое соотношение между поступающими вызовами (пакетами) в буфер и их обслуживанием сервером, но без отказов в обслуживании и с максимально возможной производительностью обслуживания. Это соотношение соответствует точкам перегиба с координатами в золотых сечениях, которые являются границами перехода между натуральными числами и обратными им значениями (дробями) относительно единичного значения средней длины очереди в буфере системы массового обслуживания.

The analysis of the main numerical, temporal and one of the probabilistic characteristics of the classical single-channe queuing system M/M/1 is carried out, the results of which allow, along with particular conclusions for each analyzed characteristic, to obtain a system-wide pattern in the form of a manifestation of the golden section in direct or indirect form. A stable ratio was obtained between incoming calls (packets) to the buffer and their service by the server, but without denial of service and with the maximum possible service performance. This ratio corresponds to inflection points with coordinates in golden sections, which are the boundaries of the transition between natural numbers and their inverse values (fractions) relative to the unit value of the average queue length in the buffer of the queuing system.

This study aimed to optimize Ultrasound-Assisted Extraction (UAE) parameters to enrich soybean oil with Myrtus communis L. (myrtle) seeds powder. The effect of the temperature and sonication time on antioxidant contents, namely total phenolics, total carotenoids, total chlorophylls and also on the antioxidant capacity was studied. The resulted optimized conditions were a temperature of 30 °C during 32.5 min and through their use, the experimental values for total phenolics, carotenoids, and chlorophylls were 103.09 ± 7.22, 1.96 ± 0.90 and, 1.88 ± 3.97 mg/kg oil, respectively. These values were very close to the predicted ones, which were 94.45 ± 10.13, 1.52 ± 0.12, and 1.57 ± 0.84 mg/kg oil, respectively. The results of the antioxidant capacity of the oil extracts indicated that the enriched oil using UAE appeared to be more potent than the control. Hence, myrtle seeds presented high amounts of bioactive compounds with antioxidant activity and were appropriate for soybean oil enrichment by UAE.
