A Study on the Key Factors for the Sustainable Development of Shared Mobility Based on TDM Theory: The Case Study from China
Authors: Wang Min , Zhang Qiaohe , Hu Jinqi , Shao Yixuan
Published: September 2024

This study is based on an investigation of shared mobility in Chinese cities, which identifies the factors affecting the sustainable development of shared mobility based on the theoretical framework of TDM (travel demand management). Through a literature review and expert interviews, the FUZZY-DEMATEL-ISM-MICMAC integration model was used to screen 21 influencing factors from aspects that fit the research theme. Triangular fuzzy numbers are used to quantify the subjective scores of nine expert groups and weaken the subjective influence of expert scores. The logical relationships among DEMATEL technology-building factors and ISM technology-based factors are divided into levels. The MICMAC technique is used to divide the types of factors according to the driving power and dependency. The results show that (1) the influence factors of the “soft strategy” and “hard strategy” in the framework of TDM are determined. In the soft strategy, we should focus on “shared mobility education” (shared mobility education, shared mobility publicity and shared mobility “environment” information) and “community organization” (community organization and advocacy and organizational interaction). In the hard strategy, we should focus on “traffic planning and measures”, “dedicated lanes”, “parking facilities”, and “financial subsidies”. (2) The ISM recursive structure model is divided into five layers. Among them, shared mobility education, shared mobility operating technology, and organizational interaction are at the deep root level, which can continuously influence other factors in the long run. (3) In MICMAC, the number of related factors is large. When making decisions on these factors, managers should comprehensively consider the correlation of factors and adjust the use of factors from an overall perspective. This study can help managers identify the key factors affecting the sustainability of shared mobility and make targeted recommendations.
Preemptive Software Project Scheduling Considering Personality Traits
Authors: Li Hongbo , Hui Qianrong , Wang Yuechen
Published: September 2024

The success of software projects is inseparable from the effective scheduling of multi-skilled human resources. In software development, employees’ personality traits often affect the performance of their work. Additionally, software developers are usually multi-tasking, which makes software development tasks preemptive. In view of this, we investigate the preemptive software project scheduling problem considering personality traits (PSPSP-PT), which aims at assigning employees with different skills and personality traits to suitable tasks and determining the start time of each task with the consideration of preemption, multi-skill, and precedence relations such that the total cost of the project is minimized. We formulate a mixed-integer linear programming model for the PSPSP-PT and design a dual priority rules-based heuristic (DPRH). Based on a benchmark dataset that is generated using a full factorial design, computational experiments are conducted to analyze the performance of our DPRH. Comparative analysis with existing algorithms reveals that our DPRH is competitive in terms of efficiency and effectiveness.

The genus Dickeya consists of Gram-negative bacteria capable of causing soft rot symptoms in plants, which involves tissue breakdown, particularly in storage organs such as tubers, rhizomes, and bulbs. These bacteria are ranked among the top ten most relevant phytopathogens and seriously threaten economically valuable crops and ornamental plants. This study employs a genomic analysis approach to taxonomically classify and characterize the resistome and virulome of two new strains, CCRMP144 and CCRMP250, identified as Dickeya dadantii. These strains were found to be the causative agents of soft rot symptoms in chili pepper (Capsicum spp.) and lettuce (Lactuca sativa), respectively, in the northeastern region of Brazil. The methodology employed in silico techniques, including tetra correlation search (TCS) and Average Nucleotide Identity (ANI) analysis, in association with a phylogenomic tree inference. TCS and ANI analysis showed that the studied strains belong to the Dickeya dadantii species. The phylogenomic analysis grouped the studied strains in the D. dadantii clade. The genomic characterization demonstrates 68 virulence genes, 54 resistances of biocide and heavy metal genes, and 23 antibiotic resistance genes. As far as we know, this is the first genomic study with Brazilian D. dadantii strains. This study demonstrates the efficacy to taxonomic classification and provides insights into the pathogenesis, host range, and adaptability of these strains which are crucial for the development of more effective management and control strategies for soft rot diseases.

The fracture strength was compared in a scratch test of coatings based on the ZrN system with the introduction of Ti, Nb and Hf, which were deposited on a titanium alloy substrate. The coatings were deposited using Controlled Accelerated Arc (CAA-PVD) technology. In coatings that simultaneously include Zr and Ti, a nanolayer structure is formed, while in coatings without Ti, the formation of a monolithic single-layer structure is observed. The comparison was carried out according to two parameters: adhesion strength to the substrate and overall coating strength. The (Zr,Hf)N coating showed better resistance to destruction, but had worse adhesion to the substrate. As a result, although the coating is retained directly in the scribing groove, a large area of delamination and destruction is formed around the groove. The (Ti,Zr,Nb)N coating, with its somewhat lower strength, has a high adhesion to the substrate; no noticeable delamination is observed along the groove boundary. In this paper, not only is the fracture resistance of various coatings deposited on a titanium alloy substrate compared, but the nature of this fracture is also investigated depending on the composition of the coatings.

This study conducted adsorption experiments using Europium (Eu(III)) on geological materials collected from Taiwan. Batch tests on argillite, basalt, granite, and biotite showed that argillite and basalt exhibited strong adsorption reactions with Eu. X-ray diffraction (XRD) analysis also clearly indicated differences before and after adsorption. By combining X-ray absorption near-edge structure (XANES), extended X-ray absorption fine structure (EXAFS), and wavelet transform (WT) analyses, we observed that the Fe2O3 content significantly affects the Eu-Fe distance in the inner-sphere layer during the Eu adsorption process. The wavelet transform analysis for two-dimensional information helps differentiate two distances of Eu-O, which are difficult to analyze, with hydrated outer-sphere Eu-O distances ranging from 2.42 to 2.52 Å and inner-sphere Eu-O distances from 2.27 to 2.32 Å. The EXAFS results for Fe2O3 and SiO2 in argillite and basalt reveal different adsorption mechanisms. Fe2O3 exhibits inner-sphere surface complexation in the order of basalt, argillite, and granite, while SiO2 forms outer-sphere ion exchange with basalt and argillite. Wavelet transform analysis also highlights the differences among these materials.

Metribuzin, a widely used triazine herbicide, persists in agricultural soils and poses significant environmental pollution threats globally. The aim of this study was to investigate the biodegradation of metribuzin by actinobacterial strains in vitro at different environmental conditions. From an initial screen of 12 actinobacterial strains, four bacteria exhibited robust growth in the presence of the metribuzin as the sole carbon source at 50 mg/L concentration. The optimization of metribuzin biodegradation under different conditions (pH, temperature and inoculum size) using a spectrophotometric method revealed that maximum degradation of metribuzin occurred at a pH of 7.2, a temperature 30 °C, and at an inoculum volume of 4%. Subsequent GC-MS validation confirmed the remarkable biodegradation capabilities of the actinobacterial isolates, where the strain C1 showed the highest rate of metribuzin degradation of 83.12%. Detailed phylogenetic identified the active strains as Streptomyces toxytricini (CH), Streptomyces stelliscabiei (B2), and two Streptomyces heliomycini (C1, C3). Structural analysis by ATR-FTIR spectroscopy confirmed the extensive biotransformation of the herbicide molecule. Our findings highlight the immense untapped potential of soil actinobacteria, particularly the Streptomyces heliomycini C1 strain, as versatile bioremediation agents for removing persistent agrochemical pollutants.

Phenols, parabens, and phthalates (PPPs) are suspected or known endocrine disruptors. They are used in consumer products that pregnant women and their progeny are exposed to daily through the placenta, which could affect offspring health. This review aims to compile data from cohort studies and in vitro and in vivo models to provide a summary regarding placental transfer, fetoplacental development, and the predisposition to adult diseases resulting from maternal exposure to PPPs during the gestational period. In humans, using the concentration of pollutants in maternal urine, and taking the offspring sex into account, positive or negative associations have been observed concerning placental or newborn weight, children’s BMI, blood pressure, gonadal function, or age at puberty. In animal models, without taking sex into account, alterations of placental structure and gene expression linked to hormones or DNA methylation were related to phenol exposure. At the postnatal stage, pollutants affect the bodyweight, the carbohydrate metabolism, the cardiovascular system, gonadal development, the age of puberty, sex/thyroid hormones, and gamete quality, but these effects depend on the age and sex. Future challenges will be to explore the effects of pollutants in mixtures using models and to identify the early signatures of in utero exposure capable of predicting the health trajectory of the offspring.

Published: September 2024

Mercury, particularly in its methylated form, poses a significant environmental and health risk in aquatic ecosystems. While the toxicity and bioaccumulation of mercury are well documented, there remains a critical gap in our understanding of the mechanisms governing mercury methylation and demethylation in aquatic environments. This review systematically examines the complex interplay of chemical, biological, and physical factors that influence mercury speciation and transformation in natural water systems. We provide a comprehensive analysis of methylation and demethylation processes, specifically focusing on the dominant role of methanogenic bacteria. Our study highlights the crucial function of hgcAB genes in facilitating mercury methylation by anaerobic microorganisms, an area that represents a frontier in current research. By synthesizing the existing knowledge and identifying key research priorities, this review offers novel insights into the intricate dynamics of mercury cycling in aquatic ecosystems. Our findings provide a theoretical framework to inform future studies and guide pollution management strategies for mercury and its compounds in aquatic environments.

Published: September 2024

Sodium hypochlorite (NaClO) has been widely utilized since the initial outbreak of coronavirus disease (COVID-19). The widespread use of NaClO means that it can directly enter aquatic ecosystems through wastewater discharge. In this study, we analyzed the expression of PPAR-γ, FAS, and ACC1, which significantly increased in larval zebrafish following exposure to 300 μg/L NaClO for 7 days. Additionally, we examined the effects of high concentrations of NaClO on zebrafish through non-targeted lipidomics and transcriptomics. A total of 44 characteristic lipid molecules were identified using non-targeted lipidomics; an absolute quantitative analysis revealed that the contents of these subclasses of lipids decreased significantly following exposure to 300 μg/L NaClO for 7 days. The levels of triglyceride (TG), phosphatidylethanolamines (PE), and diglyceride (DG) were particularly affected. Transcriptomic analysis revealed that exposure to 300 μg/L NaClO could significantly disrupt global gene transcription in larval zebrafish. Interestingly, more than 700 differentially expressed genes (DEGs) were identified, primarily associated with lipid metabolism and glycometabolism pathways. Overall, our study provided new insights into the toxicological effects of chlorine-containing disinfectants in aquatic organisms.
Finite Time Path Field Theory Perturbative Methods for Local Quantum Spin Chain Quenches
Authors: Kuić Domagoj , Knapp Alemka , Šaponja-Milutinović Diana
Published: September 2024

We discuss local magnetic field quenches using perturbative methods of finite time path field theory (FTPFT) in the following spin chains: Ising and XY in a transverse magnetic field. Their common characteristics are: (i) they are integrable via mapping to a second quantized noninteracting fermion problem; and (ii) when the ground state is nondegenerate (true for finite chains except in special cases), it can be represented as a vacuum of Bogoliubov fermions. By switching on a local magnetic field perturbation at finite time, the problem becomes nonintegrable and must be approached via numeric or perturbative methods. Using the formalism of FTPFT based on Wigner transforms (WTs) of projected functions, we show how to: (i) calculate the basic “bubble” diagram in the Loschmidt echo (LE) of a quenched chain to any order in the perturbation; and (ii) resum the generalized Schwinger–Dyson equation for the fermion two-point retarded functions in the “bubble” diagram, hence achieving the resummation of perturbative expansion of LE for a wide range of perturbation strengths under certain analyticity assumptions. Limitations of the assumptions and possible generalizations beyond it and also for other spin chains are further discussed.
Informal Settlements: A New Understanding for Governance and Vulnerability Study
Authors: Atkinson Christopher L.
Published: September 2024

This review examines current knowledge in the literature on informal settlements, specifically those contributions that include emphases on governance and the role of public administration. Given that informal settlements task the public sector with specific challenges that test the limits of infrastructure, while also presenting considerable human demands, there is a need to better understand how informal settlements and governments’ capacities to respond to such phenomena potentially deepen concerns with already vulnerable populations. After an introduction to the concept of informal settlements, the paper considers the approach to the literature review, which included an initial group of 272 papers from peer-reviewed, English-language journals, from the period 2019 to June 2024. Major themes are discussed, with opportunities for future research identified. Informal settlements are still an emerging topic within the larger land use and urban planning literature, but the significance of this research extends beyond the immediate areas of the settlements themselves to critical areas of governance and vulnerability study.
Ruderal Plant Diversity as a Driver for Urban Green Space Sustainability
Authors: Mogîldea Daniela , Biță-Nicolae Claudia
Published: September 2024

Urban development in south-eastern Europe has significant ecological consequences, such as a reduction in native plant diversity, the introduction of non-native species, and increased maintenance costs of urban green spaces. Achieving sustainable urban development requires a thorough understanding of the inventory of native plant species to better manage and conserve these areas. This study analyzed 806 vegetation surveys conducted in rural and urban areas over a 30-year period, identifying 450 plant species from 39 distinct plant communities. Our findings revealed generally low dominance index values in all communities, while Shannon diversity index values were particularly high, indicating rich species diversity despite urbanization pressures. Equality index values varied slightly, reflecting differences in species distributions. Principal component analysis (PCA) identified a substantial group of species with low abundance, which is essential for understanding and managing urban biodiversity. These findings have significant implications for urban planning and plant species conservation. Low dominance and high diversity suggest opportunities to improve urban green spaces by integrating diverse native species. In addition, the ecological and practical value of ruderal species, plants that thrive in disturbed environments, was emphasized, as well as their potential in medicine, phytoremediation, green roof design, and pollination services. Through directly correlating biodiversity indices with urban sustainability goals, our study provides useful insights for urban biodiversity management and the strategic integration of native plant species into urban landscapes.

Published: September 2024

Given the increasing momentum globally towards sustainable transportation, the remanufacturing of used electric vehicle lithium-ion batteries (EV LIBs) emerges as a critical opportunity to promote the principles of the circular economy. Existing research highlights the significance of remanufacturing in resource conservation and waste reduction. Nevertheless, detailed insights into South Africa’s (SA’s) specific capabilities and strategic approaches in the context of used EV LIBs remain sparse. By utilizing in-depth interviews with fifteen key industry stakeholders and drawing on institutional theory, this qualitative study evaluates SA’s infrastructure, technical expertise, and regulatory frameworks in the EV LIB remanufacturing sector to address this gap. The findings reveal proactive strategies, including technical expertise, sustainable infrastructure, and robust regulatory frameworks aligned with global standards. This study proposes strategic initiatives like the Interdisciplinary Innovation Hub and Mobile Remanufacturing Labs, which are analytically derived from stakeholder insights and aim to predict potential pathways for workforce development, especially in rural areas. Innovative training programs, including the Virtual Reality Consortium, Circular Economy Institutes, and the Real-world Challenges Program, will ensure a skilled workforce committed to sustainability and circular economy principles. The conclusions highlight SA’s potential to become a leader in EV LIB remanufacturing by integrating circular economy principles, enhancing technical expertise, and fostering international collaboration.
Geographic Factors Impacting the Demand for Public EV Charging: An Observational Study
Authors: Jayanath Niranjan , Pearre Nathaniel S. , Swan Lukas G.
Published: September 2024

The practicality and substitutability of electric vehicles depend on there being a fast, reliable way to recharge on round trips beyond the range of a single charge. Grouping such infrastructure into charging hubs benefits developers and operators through economies of scale and electric vehicle drivers in terms of travel logistics and passed-through cost savings. The need for charging capacity at en-route charging hubs is impacted by the following four identifiable geo-social parameters: (a) highway travel volumes, reflecting the rate at which electric vehicles are expending energy in the area; (b) local population, reflecting both the increased needs of electric vehicle owners without dedicated home chargers and the reduced needs of those commuting into a metropolitan center; (c) the quantity of competing charging stations; and (d) being on a critical interprovincial route. Twelve charging stations located in diverse locations around Nova Scotia, Canada, were evaluated in terms of these four parameters, and their recorded use was investigated from a dataset of 26,000 charging events between April 2022 and April 2024. The regression reveals that there are strong positive correlations between demand for fast charging and (a) traffic volumes (45%) and (c) being on an interprovincial route (42%), while there is only a very weak correlation with (b) local population (2%). Interestingly, there is only a weak negative correlation with (c) the number and capacity of nearby competing chargers (−6%), suggesting that either in short-term route choice or longer-term vehicle choice, the presence of chargers encourages electric vehicles.
Privacy-Preserving Electric Vehicle Charging Recommendation by Incorporating Full Homomorphic Encryption and Secure Multi-Party Computing
Authors: Liu Yiqi , Ju Jiaxin , Li Zhiyi
Published: September 2024

Electric vehicle (EV) charging recommendation can significantly improve global planning performance, corresponding to an increasing risk of privacy leakage. Based on this, this paper investigates the privacy data preservation strategy during the interaction between EVs and charging facilities. It proposes a privacy preservation strategy that aims to ensure EV information security. In a cloud computing environment, users do not want other users and cloud providers to have access to their personal information, which is precisely the problem that secure multi-party computing (SMPC) can solve. At present, full homomorphic encryption (FHE) can solve the problem of user data privacy preservation in cloud computing and big data environments and can realize the whole encryption process. Therefore, a more reasonable charging station selection scheme is provided under the computation of privacy preservation strategies incorporating the FHE-SMPC method. The effectiveness and implementation feasibility of the designed privacy preservation strategy in practical applications is verified through testing and comparative analysis. The results show that the developed strategy can significantly reduce the risk of privacy leakage with limited communication resources and computation time consumption. The results provide new perspectives and methodologies for interactive privacy preservation between EVs and charging stations, with application potential.
Comparative Assessment of Expected Safety Performance of Freeway Automated Vehicle Managed Lanes
Authors: Sarran Jana McLean , Hassan Yasser
Published: September 2024

The use of dedicated lanes, known as managed lanes (MLs), on freeways is an established traffic management strategy to reduce congestion. Allowing automated vehicles (AVs) in existing MLs or dedicating MLs for AVs, referred to as AVMLs, has been suggested in the literature as a tool to improve traffic operation and safety performance as AVs and driver-operated vehicles (DVs) coexist in a mixed-vehicle environment. This paper focuses on investigating the safety impacts of deploying AVMLs on freeways by repurposing general-purpose lanes (GPLs). Four ML strategies considering different lane positions and access controls were implemented in a traffic microsimulation under different AV market adoption rates (MARs) and traffic demand levels, and trajectories were used to extract rear-end and lane change conflicts. The time-to-collision (TTC) surrogate safety measure was used to identify critical conflicts using a time threshold dependent on the type of following vehicle. Rates of conflicts involving different vehicle types for all ML strategies were compared to the case of heterogeneous traffic. The results indicated that the rates of rear-end conflicts involving the same vehicle type as the lead and following vehicle, namely DV-DV and AV-AV conflicts, increased with ML implementation as more vehicles of the same type traveled in the same lane(s). By comparing the aggregated conflict rates, the design options that were deemed to negatively impact traffic efficiency and capacity were also found to negatively impact traffic safety. However, other ML options were found to be feasible in terms of traffic operation and safety performance, especially at traffic demand levels below capacity. Specifically, one left-side AVML with continuous access was found to have lower or comparable aggregated conflict rates compared to heterogenous traffic at 25% and 50% MARs, and, thus, it is expected to have positive or neutral safety impacts.
Influence of an Automated Vehicle with Predictive Longitudinal Control on Mixed Urban Traffic Using SUMO
Authors: Heckelmann Paul , Rinderknecht Stephan
Published: September 2024

In this paper, an approach to quantify the area of influence of an intelligent longitudinally controlled autonomous vehicle in an urban, mixed-traffic environment is proposed. The intelligent vehicle is executed with a predictive longitudinal control, which anticipates the future traffic scenario in order to reduce unnecessary acceleration. The shown investigations are conducted within a simulated traffic environment of the city center of Darmstadt, Germany, which is carried out in the traffic simulation software “Simulation of Urban Mobility” (SUMO). The longitudinal dynamics of the not automated vehicles are considered with the Extended Intelligent Driver Model, which is an approach to simulate real human driver behavior. The results show that, in addition to the energy saving caused by a predictive longitudinal control of the ego vehicle, this system can also reduce the consumption of surrounding traffic participants significantly. The area of influence can be quantified to four vehicles and up to 250 m behind.

Published: September 2024

Although cicadas have traditionally been considered pests of little or no importance, in recent decades, an increase in damages is being recorded in olive groves of southern Spain. New agricultural practices that affect soil management are behind it. During 2024, intensive sampling has been carried out in an organic grove with herbaceous cover (VC2), and in a second one with mixed vegetation cover (VC1, in which the crushed remains of the annual pruning are added). In both ecological groves, inventories of the vegetation have been carried out, as well as intensive sampling in the olive canopy, with the densities of oviposition injuries being recorded and compared with respect to conventional management (CONV). The objectives of this study are to compare the three managements based on the density of oviposition injuries, to determine the priority areas for cicadas’ oviposition within the trees; and to develop a sampling method to assess damage over large areas. The results show significant increases in the density of injuries in organic groves, with maximum values recorded in the olive grove with mixed cover. Oviposition injuries show an altitudinal gradient distribution, with maximum values in the lower zone of the trees. The factors involved are discussed.

Esse trabalho visa identificar os recursos argumentativos utilizados pelo programa “Alienígenas do Passado”, do History Channel, para sedimentar a versão  que eles apresentam a respeito da História da África e, dessa forma, colaborar, com o debate acerca da História Pública, bem como com os estudos africanistas. A presente pesquisa partiu da ideia de que a história dos povos africanos ainda é difundida, principalmente nos países ocidentais, de maneira generalizante e preconceituosa, geralmente resumida em escravidão e colonialismo, esquecendo que o continente é um território gigante e plural, com inúmeros povos, organizados em diferentes formas sociais, culturais, políticas e religiosas muito antes da chegada do homem branco. Nesse sentido, o campo da História Pública torna-se uma excelente ferramenta para mudar estas narrativas colonialistas. Assim, antes de adentrar o referido programa de televisão, cujo cerne é colocar seres extraterrestres no centro da humanidade, apresentei os conceitos de negacionismo, revisionismo ideológico, fake news e teoria da conspiração.

Nesse trajeto, discutimos o desenvolvimento da cibercultura e da Sociedade em Rede, abordando tanto as oportunidades quanto os desafios impostos às práticas historiográficas contemporâneas. Compreendemos que as TDIC transformaram significativamente o campo da História e das metodologias de ensino ao oferecer novos meios de acessar, analisar e disseminar informações e conhecimento. Destaca-se entre essas transformações a necessidade de os historiadores adotarem um olhar crítico sobre as ferramentas digitais, enfatizando a importância da interação humana na pesquisa histórica. Por fim, acreditamos que, embora as TDIC possam oferecer novos caminhos para a pesquisa histórica, é fundamental manter métodos críticos e reflexivos na abordagem das fontes digitais.
O PENSAMENTO MÉDICO BRASILEIRO NA DÉCADA DE 1840 NO BRASIL
Authors: Pinheiro Oliveira Maria Fernanda
Published: September 2024

Compreendendo que o saber médico do século XIX tinha como base uma abordagem que correlacionava ordem social e saúde pública, é possível observar nas teses dos médicos aspirantes ao título de "doutor" uma recorrência de ideias sobre o controle do espaço urbano e da população considerada perigosa - tais como delinquentes, libertinos, prostitutas, loucos e vagabundos. Essas teses abordavam temas como medicina legal, legislação criminal, prostituição, aborto, frenologia e higiene das prisões, dentre outros assuntos relacionados, indicando "falhas" na legislação criminal decorrentes da falta de consideração do conhecimento médico na formulação das leis. Diante disso, esta nota de pesquisa tem como objetivo apresentar o tema da frenologia no discurso médico brasileiro, na década de 1840 no Brasil. Este texto parte de uma parcela dos resultados da pesquisa de Iniciação Científica, “As aproximações entre direito e medicina entre as décadas de 1840 e 1860 no Brasil” financiada pelo CNPQ (Conselho Nacional de Desenvolvimento Científico e Tecnológico) e finalizada no ano de 2023.

Published: September 2024

O presente artigo propõe uma reflexão sobre as perceções dos professores e dos pais e/ou encarregados de educação sobre as repercussões culturais nas práticas educativas no ensino básico (1ª a 7ª classes) em Moçambique e particularmente na província de Sofala. O contexto social moçambicano é caracterizado por um vasto mosaico cultural e cada cultura é particular na forma de ser e estar, o que se concretiza em especificidades inerentes à educação familiar. Este trabalho surge da necessidade de compreensão do alcance das questões culturais nas práticas educativas escolares. O sistema educativo tem de ter em conta as práticas culturais, por serem portadoras de valores e por se afirmarem na relação escola-família como um espaço de mediação cultural. Para o efeito foi realizado um estudo exploratório de natureza quantitativa, tendo sido questionados 407 professores e 750 pais e/ou encarregados de educação. Os instrumentos de recolha de dados foram construídos para este estudo com o objetivo de caracterizar as perceções de pais e professores sobre a relação família-escola. Os resultados obtidos apontam para a compressão de que os pais e professores consideram que os fatores culturais influenciam a relação família-escola e a aprendizagem escolar, sobretudo nos primeiros anos de escolaridade, o que obriga o professor a promover a consideração da diversidade de valores para o bem da educação. Salienta-se ainda a relevância de uma abordagem multicultural e multilinguística na relação entre as escolas, enquanto organizações, os professores e os pais ou encarregados de educação.

Background: Melanoma is one of the most complex and invasive cancers in the world, accounting for the most deaths among skin cancers. This study investigated the effects of melatonin (MLT)-treated RAW264.7 cell lines on A-375 human melanoma cell lines. Methods: RAW264.7 and A-375 cells were cultured and passaged separately and then treated with 0 μM, 50 μM, 75 μM, 100 μM, 150 μM, and 200 μM concentrations of MLT. In addition, the survival rate of these cells was checked by trypan blue staining. A-375 cells were exposed to RAW264.7 cells treated with MLT for 24 hours, and their viability was evaluated with trypan blue. Results: After the colonization of RAW264.7 cells and treatment with different concentrations of MLT for 24 hours, it was observed that the growth and differentiation of RAW264.7 cells decreased at concentrations of 150 μM and 200 μM. In the case of A-375 cells, after 24 hours of treatment with different concentrations of MLT, the growth of malignant cells was inhibited in a dose-dependent manner. When MLT-treated RAW264.7 cells were placed in the vicinity of A-375 cells for 24 hours, the density of RAW264.7 cells was low at concentrations of 150 and 200 μM MLT, and the growth of A-375 cells was inhibited accordingly. The same results were obtained when cell viability was measured by MTT. Conclusion: Our findings revealed that MLT, at concentrations of 150 μM and 200 μM, inhibited the growth of A-375 cells by inhibiting the growth and reducing the differentiation of RAW macrophages. Therefore, this substance can be used in the mentioned concentrations to treat melanoma. It is also possible to examine the effect of MLT on melanoma cell line in different periods.

Background: COVID-19, a newly discovered infectious disease, with a wide range of intensity, has recently become the primary global health issue. Antibiotics are medications designed against microorganisms that are typically not effective in viral infections such as COVID-19. Considering that more than a third of physicians prescribe antibiotics for COVID-19 patients, it was essential to examine the efficacy of these medications. Methods: This cross-sectional study was conducted on 128 hospitalized COVID-19 patients in Iran and performed appropriate statistical tests, including the Chi-square test, and regression analyses, using SPSS 26 (IBM, USA). The missing data were managed properly. Results: The study included 128 COVID-19 patients with a mean age of 58.7 years, and 46.9% were male. Age was the only factor significantly associated with mortality and hospitalization. However, patients with abnormal potassium, prothrombin, partial thromboplastin time, urea, creatinine, and albumin levels had significantly different hospitalization periods and mortality rates. The most commonly prescribed antibiotics were ceftriaxone, hydroxychloroquine, and azithromycin. In addition, patients who took vancomycin had a significantly higher mortality rate. Conclusion: Our findings revealed that age and gender could significantly impact hospital stay duration and mortality rates. Considering that certain antibiotics were linked to prolonged hospital stays, bacterial infection during COVID-19 was not significantly related to increased mortality, which questions the necessity of antibiotics for all patients. The study identified age, gender, and certain lab parameters as associated factors with COVID-19 outcomes. Since its retrospective nature and small sample size limit the findings’ applicability, larger studies are needed to confirm the findings and explore other potential risk factors.

Alzheimer’s disease (AD) is a debilitating mental disorder that causes a gradual decline in cognitive function and memory loss. The disease is associated with the accumulation of amyloid beta (Aβ) peptide-containing plaques outside the cells and the formation of neurofibrillary tangles (NFTs) inside the neurons due to tau protein hyperphosphorylation. AD is considered a hypometabolic disease at the cellular level, characterized by decreased adenosine triphosphate (ATP) levels and elevated reactive oxygen species (ROS) levels. Mitochondria, the cellular powerhouse, provide energy for cellular metabolism and protect cells against excessive oxidative stress. During disease progression, toxic Aβ causes significant disruptions in mitochondria bioenergetics, proteolytic systems, electron transport chains, mitophagy, and mitochondria DNA (mtDNA), leading to an accumulation of damaged organelles. This results in a disruption of the cellular energy demands, ROS scavenging pathways, and autophagy. The compromised mitochondria function caused by toxic Aβ exacerbates the development and progression of AD. This review aimed to provide current insights into the interactions between mitochondria and Aβ in AD pathogenesis, highlighting the pivotal role of mitochondrial dysfunction in the disease’s progression.

Systems known in the pharmaceutical sciences have less use for drug release and control. In addition, these standard systems in pharmacy have no effective control over drug concentrations. The main problem with conventional drug delivery systems (DDS) is the unpredictability of different plasma concentrations. However, drug control systems have provided an excellent way to release the drug. In this regard, osmotic pumps are the best and most promising systems for the controlled delivery and release of drugs. They are commonly used for oral and injectable use, several of which are also commercialized and widely accepted by patients, especially the antihypertensive products. The purpose of this study is to introduce and compare different types of osmotic pumps in pharmacy.

Neuroinflammation (NI) is defined as a condition in which neurons undergo inflammatory processes, which can lead to transient and permanent functional disruptions in neurons. These disruptions can initiate various neuropsychiatric conditions such as Alzheimer’s and Parkinson’s diseases. Significant findings have been reported regarding the underlying conditions such as infections and oxidative stress that contribute to neuronal inflammation in recent years. As such, studies have introduced many valuable approaches to alleviate NI and its subsequent medical conditions. Pharmacological approaches have long been of interest to patients and therapists, particularly in the context of NI, where significant achievements have been made. Scrutinizing the literature indicates that natural remedies have gained considerable attention among researchers in this regard. Therefore, the current review was conducted to collect and classify relevant studies to provide reliable information on the role of natural remedies in NI management.
