Authors: Lei Yang , Xu Lihong , Wang Minggui , Sun Sheng , Yang Yuhua , Xu Chao
Published: July 2024

Applying biochar to tomato cultivation presents a beneficial strategy that can enhance both yield and fruit quality, crucial for sustainable agricultural practices. However, a review of the existing literature on the effects of biochar indicates a significant variability in outcomes, suggesting the need for a more nuanced understanding of biochar application in relation to soil and biochar conditions. This study conducts a meta-analysis on the literature published before March 2024 to investigate the impacts of biochar properties, agricultural practices, and soil properties on the yield and fruit quality of tomato. The results indicated that biochar application significantly increased tomato yield by 29.55%, total soluble solids (TSS) by 4.28%, and vitamin C (VC) by 6.77% compared to control treatments without biochar, especially at higher application rates. However, the benefits may wane over time due to biochar aging in the soil, requiring periodic replenishment. The type of biochar and pyrolysis temperature, particularly wood and straw biochar pyrolyzed at 401–500 °C, were found to be most effective for boosting yield and quality. Additionally, initial soil properties, including soil organic matter, pH, and nutrient levels, interact with biochar to influence outcomes, with biochar being particularly beneficial for soils with a high bulk density and low soil organic matter (SOM) or nutrient deficiencies. This study underscores the potential of biochar as a multifaceted strategy in tomato cultivation, enhancing not only yield but also the nutritional value of the fruit, while simultaneously improving soil health.

Published: July 2024

This pioneering study uniquely identifies and characterizes the presence of algal species, mainly Spirulina, from water reservoirs in the Kohat district of Pakistan, a previously unstudied region for microalgae dynamics. Conducted over one year, from July 2022 to June 2023, the study examined 156 samples from 26 freshwater bodies in Kohat. Only one sample from Usterzai (pH 8.6 ± 0.08, TDSs 313 ± 0.81 mg/L, DO 4.50 ± 0.05 mg/L, EC 540 ± 0.81 µS/cm) contained Spirulina sp., highlighting its rarity and specific environmental preferences. The other 155 samples, with varying parameters, contained different microalgae. Microscopic analysis further confirmed the presence of Spirulina in only one sample. The morphological and molecular analyses of the isolated Spirulina culture showed variability within the population, with phylogenetic analysis illuminating closer relationship with Arthrospira platensis. While multivariate analyses identified key environmental parameters influencing algal species distribution, the selective presence of Spirulina was found less relevant, which requires further investigation in terms of nutrient availability, microbial interactions, or subtle variations in water chemistry for ecological preferences and adaptations.
Literary Analysis of the Connection between Urban Innovations and Sustainable Development Goals (SDGs)
Authors: Cheshmehzangi Ali , Zou Tong
Published: July 2024

The connections between urban areas and innovations have been widely discussed and well recognized in both academia and practice. Notably, urban innovation (UI), as a type of innovation and/or innovation system, can significantly contribute to achieving sustainable development goals (SDGs). However, current research on UI and SDGs is still limited. To fill this research gap, this systematic literature review is conducted using published work in the first half of the SDG era, i.e., 2015 to 2022. It proposes the hierarchy of the urban innovation level and the SDG pizza model with a definition of UI. This systematic literature review is based on four main steps: literature selection, abstract screening, full-text review, and data extraction. In step #1, the keyword “urban innovation” is used to identify the initial publications. Next, an inclusion criterion is applied in step #2, which covers UI in the abstract. Then, an exclusion criterion is used in step #3, which covers the connection between/among UIs and any one or more SDGs. Step #4 is mainly data extraction following the full text review. This paper provides detailed results and discussions with a few critical views on this nexus analysis. This paper contributes to existing research by highlighting the importance of the innovation-sustainability nexus, particularly from the SDG perspective.
Spatiotemporal Evolution and Drivers of Carbon Storage from a Sustainable Development Perspective: A Case Study of the Region along the Middle and Lower Yellow River, China
Authors: An Shu , Duan Yifang , Chen Dengshuai , Wu Xiaoman
Published: July 2024

Carbon storage (C-storage) is a critical indicator of ecosystem services, and it plays a vital role in maintaining ecological balance and driving sustainability. Its assessment provides essential insights for enhancing environmental protection, optimizing land use, and formulating policies that support long-term ecological and economic sustainability. Previous research on C-storage in the Yellow River Basin has mainly concentrated on the spatiotemporal fluctuations of C-storage and the investigation of natural influencing factors. However, research combining human activity factors to explore the influences on C-storage is limited. In this paper, based on the assessment of the spatiotemporal evolution of C-storage in the region along the Middle and Lower Yellow River (MLYR), the influences of anthropogenic and natural factors on C-storage were explored from the perspective of sustainable development. The findings reflected the relationship between socio-economic activities and the ecological environment from a sustainable development perspective, providing important scientific evidence for the formulation of sustainability policies in the region. We noticed the proportion of arable land was the highest, reaching 40%. The increase of construction land because of the fast urbanization mainly came from arable land and grassland. During the past 15 years, the cumulative loss of C-storage was 71.17 × 106 t. The high-value of C-storage was primarily situated in hilly areas, and the area of C-storage hotspots was shrinking. The aggregation effect of low-value C-storage was strengthening, while that of high-value C-storage was weakening. The dominant factors (q > 0.5) influencing the spatiotemporal variation of C-storage in the region along the Middle Yellow River (MYR) were temperature and precipitation, while the primary factor in the region along the Lower Yellow River (LYR) was temperature. Overall, meteorological factors were the main determinants across the entire study area. Additionally, compared to the MYR, anthropogenic factors had a smaller impact on the spatiotemporal evolution of C-storage in the LYR, but their influence has been increasing over time.
Exploring Digital Learning Opportunities and Challenges in Higher Education Institutes: Stakeholder Analysis on the Use of Social Media for Effective Sustainability of Learning–Teaching–Assessment in a University Setting in Qatar
Authors: Al-Hail Maryam , Zguir Mariem Fekih , Koç Muammer
Published: July 2024

The use of social media (SM) platforms in higher education has seen significant growth since the global pandemic disrupted traditional learning methods and forced stakeholders to explore alternatives. This trend is expected to continue with the rise of newer digital learning platforms, tools, programs and pedagogies, particularly within the context of the Fourth Industrial Revolution and the evolution towards Education 4.0 and Education 5.0. Despite a significant level of research into SM’s role in informal learning, there has been limited exploration of its integration into pedagogical practices, particularly regarding assessment challenges and innovations in university settings. Additionally, there is scarce research on mobile applications in academics, hindering the effective integration of SM platforms into curricula. This study addresses these gaps by examining stakeholder perceptions of using SM for educational purposes in a university setting in Qatar. Following a comprehensive and comparative literature review and analysis, a thematic analysis of interviews with 20 stakeholders revealed that SM platforms go beyond communication, serving as tools to enhance professional identity, reputation, research profiles, knowledge dissemination, and social practices, but they lack methodologies to integrate effective learning, either independently or in formal learning/teaching/assessment settings. This study proposes a framework to optimize the use of SM platforms, with a particular focus on sustainability, for lifelong learning and knowledge-based societies leading to more sustainable and prosperous economies. The findings encourage the reconsideration of digital assessment and the expansion pedagogical practices in alignment with modern social learning through an expansive array of SM tools and platforms.

Published: July 2024

Forest managers need inventory data and information to address sustainability concerns over extended temporal horizons. In situ information is usually derived from field data and computed using appropriate equations. Nonetheless, fieldwork is time-consuming and costly. Thus, new technologies like Light Detection and Ranging (LiDAR) have emerged as an alternative method for forest assessment. In this study, we evaluated the accuracy of geostatistical methods in predicting the Site Index (SI) using LiDAR metrics as auxiliary variables. Since primary variables, which were obtained from forestry inventory data, were used to calculate the SI, secondary variables obtained from LiDAR surveying were considered and multivariate kriging techniques were tested. The ordinary cokriging (CK) method outperformed the simple cokriging (SK) and Inverse Distance Weighted (IDW) methods, which was interpolated using only the primary variable. Aside from having fewer SI sample points, CK was proven to be a trustworthy interpolation method, minimizing interpolation errors due to the highly correlated auxiliary variables, highlighting the significance of the data’s spatial structure and autocorrelation in predicting forest stand attributes, such as the SI. CK increased the SI prediction accuracy by 36.6% for eucalyptus, 62% for maritime pine, 72% for pedunculate oak, and 43% for cork oak compared to IDW, outperforming this interpolation approach. Although cokriging modeling is challenging, it is an appealing alternative to non-spatial statistics for improving forest management sustainability since the results are unbiased and trustworthy, making the effort worthwhile when dense secondary variables are available.

Authors: Clemente Erica , Della Corte Marcello , Ferrara Micol , Cerchia Elisa , Catti Massimo , Garazzino Silvia , Gerocarni Nappo Simona , Bonora Stefano
Published: July 2024

Urinary tract infections (UTIs) are the most common bacterial infections in children, occurring both in children with normal urinary tracts and in ones with urinary tract abnormalities. Children with UTIs can present relevant clinical symptoms and risk long-term consequences. Current recommended preventive measures include chemoprophylaxis and dietary supplements such as cranberry, probiotics and vitamins A and E. Although chemoprophylaxis still represents the gold standard, it raises concerns about antimicrobial resistance. N-acetylcysteine (NAC), a precursor of the antioxidant glutathione, has been proven both to inhibit biofilm formation and to destroy developed biofilms. In adults, NAC has been demonstrated to prevent UTIs and to improve the effect of antibiotics, but so far it has not been analyzed as an antimicrobial option for pediatric UTIs. In this work, we aim to discuss the current applications of NAC in adult urology and its future possible evolutions in pediatric urology.

Published: July 2024

Endocrine-disrupting chemicals (EDCs) are chemicals that can interfere with homeostatic processes. They are a major concern for public health, and they can cause adverse long-term effects such as cancer, intellectual impairment, obesity, diabetes, and male infertility. The endocrine system is a complex machinery, with the estrogen (E), androgen (A), and thyroid hormone (T) modes of action being of major importance. In this context, the availability of in silico models for the rapid detection of hazardous chemicals is an effective contribution to toxicological assessments. We developed Qualitative Gene expression Activity Relationship (QGexAR) models to predict the propensities of chemically induced disruption of EAT modalities. We gathered gene expression profiles from the LINCS database tested on two cell lines, i.e., MCF7 (breast cancer) and A549 (adenocarcinomic human alveolar basal epithelial). We optimized our prediction protocol by testing different feature selection methods and classification algorithms, including CATBoost, XGBoost, Random Forest, SVM, Logistic regression, AutoKeras, TPOT, and deep learning models. For each EAT endpoint, the final prediction was made according to a consensus prediction as a function of the best model obtained for each cell line. With the available data, we were able to develop a predictive model for estrogen receptor and androgen receptor binding and thyroid hormone receptor antagonistic effects with a consensus balanced accuracy on a validation set ranging from 0.725 to 0.840. The importance of each predictive feature was further assessed to identify known genes and suggest new genes potentially involved in the mechanisms of action of EAT perturbation.

Authors: Manso Margarida , Soares João Diogo , Henriques Margarida , Botelho Francisco , Silva Carlos , Cruz Francisco
Published: July 2024

Urgency urinary incontinence (UUI) refractory to medical treatment poses significant challenges despite advancements. This study evaluates the efficacy of intravesical botulinum toxin for UUI and identifies factors influencing treatment outcomes. Among 368 women receiving botulinum toxin injections, 74.5% achieved a complete discontinuation of pad usage. Predictors of efficacy included lower pre-treatment pad usage and the absence of prior sling placement. Patients often required repeat injections (60.3%), with younger age and satisfaction correlating with treatment repetition. The interval between injections averaged 18 months, influenced by logistical challenges and patient preferences. Despite concerns about diminishing efficacy, subjective perceptions did not align with objective findings. Limitations include retrospective analysis and heterogeneous clinical records. In conclusion, intravesical botulinum toxin is effective for UUI, with pre-treatment pad usage and sling placement history influencing outcomes and patient characteristics influencing treatment repetition.
Innovation in Water Management: Designing a Recyclable Water Resource System with Permeable Pavement
Authors: Yang Shu-Rong , Chen Xing-Rong , Huang Hao-Xuan , Yeh Hsin-Fu
Published: July 2024

Taiwan’s unique geographic environment combined with climate change leaves it particularly vulnerable to water shortage issues. A new water resource recycling system that adheres to a Low Impact Development (LID) concept and utilizes existing permeable pavement techniques to mitigate water scarcity is presented in this study. The design routes water at the base and subbase layers of a permeable pavement toward a planter box in the median divider island or box culvert below the median divider island. Once the runoff has flowed into the bottom of the planter box or box culvert, it is available for plants via soil capillary action. Through evaporation or transpiration, the water is then returned to the atmosphere and integrated into the water cycle for localized microclimates. This study used a 3D printer to create a small-scale model of the proposed design. Using this small-scale 3D model, a series of capillary experiments were conducted to evaluate the permeable pavement water recycling system. Because the small-scale model is not suitable for long-duration tests, soil column experiments were also used. The soil was compacted to different relative compactions for a 3D model and the soil column experiments were used to evaluate the capillary rise height of the soil. The results showed that when using a silt with low plasticity soil (ML), under low relative compaction, the capillary water can reach the rooting level of appropriately selected plants. Therefore, if the soil around vegetation is correctly compacted, the vegetation’s roots will have access to stored water. The proposed permeable pavement water recycling system represents a practical approach to managing stormwater runoff and achieving water conservation objectives. This innovative design not only aims to conserve and protect water resources but also supports sustainable water management practices, thereby helping to mitigate the impacts of climate change.

Published: July 2024

Over the past few decades, climate warming has driven alterations in both the discharge volume and biogeochemical composition of Arctic riverine fluxes. This study investigated the content of macro- and microelements in the lower reaches of the Ob River (western Siberia). Seasonal sampling was performed over a four-year period (2020–2023) during the main hydrological seasons (winter low water, spring-summer floods, and early fall low water) at three river stations. The results revealed significant seasonal variations in the elemental content of the Ob River water associated with changes in catchment inputs, physical and chemical conditions of the aquatic environment, and the amount and composition of incoming suspended sediment. During high water flow events in the Ob River, the concentration of suspended solids increased substantially. During the winter period when the Ob River was ice-covered, a two- to three-fold rise was observed in the concentration of Na, Mg, Ca, K, Si, and Mn. Having accounted for these seasonal variations in water chemistry, we were able to refine our estimates of elemental export to the Arctic Ocean. Compared to estimates from previous studies, we observed 2.3-fold higher dissolved loads of Mn, and the dissolved loads were higher by 2.1-fold for Zn, 1.6-fold for Fe, and 1.4-fold for Pb. The observed rise in elemental export is likely attributable to a confluence of factors, including permafrost thaw, enhanced water inflow from wetland catchments, and intensifying snowfall leading to increased flood runoff.

Published: July 2024

Drought research is needed to understand the complex nature of drought phenomena and to develop effective management and mitigation strategies accordingly. This study presents a comprehensive regional frequency analysis (RFA) of 12-month meteorological droughts in the Kızılırmak Basin of Turkey using the L-moments approach. For this purpose, monthly precipitation data from 1960 to 2020 obtained from 22 meteorological stations in the basin are used. In the drought analysis, the Standard Precipitation Index (SPI), Z-Score Index (ZSI), China-Z Index (CZI) and Modified China-Z Index (MCZI), which are widely used precipitation-based indices in the literature, are employed. Here, the main objectives of this study are (i) to determine homogeneous regions based on drought, (ii) to identify the best-fit regional frequency distributions, (iii) to estimate the maximum drought intensities for return periods ranging from 5 to 1000 years, and (iv) to obtain drought maps for the selected return periods. The homogeneity test results show that the basin consists of a single homogeneous region according to the drought indices considered here. The best-fit regional frequency distributions for the selected drought indices are identified using L-moment ratio diagrams and ZDIST goodness-of-fit tests. According to the results, the best-fit regional distributions are the Pearson-Type 3 (PE3) for the SPI and ZSI, generalized extreme value (GEV) for the CZI, and generalized logistic distribution (GLO) for the MCZI. The drought maps obtained here can be utilized as a useful tool for estimating the probability of drought at any location across the basin, even without enough data for hydrological research.

Published: July 2024

For hydraulic engineering, accurate geometric modeling is crucial for design, analysis, and maintenance. In recent years, point cloud technology, with its high precision and detailed data capture capabilities, has gradually become the preferred method for geometric modeling in hydraulic engineering. However, traditional point cloud processing methods exhibit slow data processing speeds and poor mesh quality when reconstructing 3D models. Therefore, we have studied the meshing method for the 3D reconstruction of large-scale discrete point cloud data and proposed a meshing method based on the Delaunay criterion and the growth method to achieve rapid meshing of discrete point cloud data. To demonstrate the efficiency and convenience of the proposed method, point cloud reconstruction experiments are conducted on various buildings. We compare our approach with the Poisson, BPA, and ONet methods. Additionally, we apply it to the Jiangsu Gaogang Water Conservancy Hub in China. The results show that our proposed method is superior in both reconstruction quality and efficiency, providing a promising solution for the reconstruction of 3D building models from point clouds.

Authors: Foster Emani , Bunn Jennifer A.
Published: July 2024

Several youth volleyball tournaments are played across multiple consecutive days with athletes averaging 3–4 matches/day. This study evaluated the differences in workload of female youth volleyball athletes across days and by position during multi-day tournaments. Athletes (n = 22, 16.4 ± 0.4 years) wore an accelerometer during 12 two- and three-day tournaments. Workload was measured via kinetic energy (KE, J/lb), total jumps (TJ), high jumps (HJ, >51 cm), average jump height (cm), and percentage of high stress movements (%) via VERT accelerometers. Data were analyzed across days and by position as an average per day and analyzed via repeated measures analyses of variance. Across days, workload averages ranged 484.8–558.0 J/lb for KE, 27.3–31.2 TJ/match, 37.5–37.9 cm/jump, 5.2–6.5 HJ/match, and 20.1–20.7% high stress movements/match, with no difference (p = 0.300). Setters (49.2 ± 24.3 jumps) jumped more than liberos (13.0 ± 6.8 TJ, p = 0.005), and middles (45.8 ± 4.1 cm) jumped higher than all other positions (setters: 28.8 ± 3.6 cm, outside hitters: 41.3 ± 4.2 cm, and liberos: 27.0 ± 4.1 cm, p = 0.000–0.044). Athletes appeared to perform and recover sufficiently between days of play such that their external load was not affected. The level of competition tends to become more evenly matched as the tournament progresses, thus there may have been less physical demand early in the tournaments due to unequal competition levels compared to the final day of the tournament.

Análise de dinâmica por Métodos dos Elementos finitos (MEF) em uma peneira vibratória
Authors: Santos Pedro Henrique Nascimento , Silva Leandro Cardoso da
Published: July 2024

Este estudo aborda a análise dinâmica de uma peneira vibratória horizontal utilizando o Método dos Elementos Finitos (MEF). Este equipamento é indispensável em muitas indústrias que processam materiais granulares devido à sua capacidade de separar partículas de diferentes tamanhos com eficiência e precisão. O uso eficiente de uma peneira vibratória depende de uma análise cuidadosa do campo vibratório gerado pelos excitadores que acionam a máquina, pois a amplitude e a frequência de vibração devem ser ajustadas para atender às necessidades específicas do processo de classificação. Um projeto inadequado pode levar a tensões excessivas na estrutura da peneira, resultando em fadiga e necessidade de manutenção prematura. A relação entre amplitude e frequência de vibração é fundamental para o desempenho da máquina. Quando a frequência natural da peneira é igual à frequência de excitação, ocorre a ressonância, gerando tensões elevadas na estrutura da máquina. Portanto, é necessário um estudo cuidadoso para determinar a frequência natural da peneira e ajustar a frequência de excitação para evitar a ressonância. Para alcançar esses objetivos, foram aplicadas diversas técnicas de monitoramento e análise. Utilizou-se o software Solidworks Simulation para simular o comportamento dinâmico da peneira vibratória sob diferentes condições de operação. A análise de vibração foi utilizada para identificar padrões de vibração que indicam possíveis desalinhamentos, desgastes ou falhas iminentes em componentes rotativos. A análise térmica monitorou as variações de temperatura, identificando áreas com aquecimento excessivo. A técnica de termografia foi utilizada para obter uma visão detalhada da distribuição de temperatura nos equipamentos. Os resultados mostraram que a implementação do sistema de monitoramento contínuo e das técnicas de manutenção preditiva resultou em uma redução significativa das paradas não programadas das bombas de vácuo. A análise modal revelou fragilidades no projeto, propondo a adição de elementos para aumentar a rigidez nas regiões críticas. A análise de tensões identificou pontos de alta tensão que requerem reforço estrutural.

Published: July 2024

This research examines the effects of technostress on educators' productivity within Jordan's higher education sector, highlighting gender differences. Technostress, characterized by techno-overload, techno-invasion, techno-complexity, techno-insecurity, and techno-uncertainty, adversely affects productivity. The study gathered data from 500 educators through a structured online survey, achieving a 73% response rate. Analysis revealed that technostress generally decreases productivity, with a more pronounced negative impact on male educators than females. The findings underscore the necessity for targeted interventions to mitigate technostress, particularly among male educators. Strategies recommended include training programs, policy adjustments, and organizational support to enhance the digital teaching environment. This study contributes to the understanding of technostress in Jordanian educational settings. It offers practical recommendations for enhancing e-learning practices and improving the overall educational experience and productivity in Jordan's higher education sector.
Parametric Optimization of Structural Frame Design for High Payload Hexacopter
Authors: Öztürk Osman
Published: July 2024

For drones, the use of which has been increasing recently for load carrying, lightweight drone frame design is significant for increased flight time and payload capacity. Drones are produced in different configurations with three, four, or six rotors, and in different sizes depending on the purpose of use. While agility is more important in three and four rotor drone applications, six-rotor and relatively large-bodied drones are preferred in cases such as load carrying. When the body structure has to be large, lightening the design becomes very critical. Lightweight designs can be achieved by two commonly used methods for structural optimization: topology optimization and parametric optimization. Topology optimization is an advanced method that can significantly reduce weight but is expensive and time-consuming. Parametric optimization is a more practical approach to conventional manufacturing methods and was used in this study. This study aims to first simplify the hexacopter frame model and define key geometric parameters for mass-decreasing optimization. Finite element analysis simulations were used to evaluate the strength and deformation of the frame under various design scenarios. The results showed that parametric optimization successfully reduced the weight of the hexacopter frame while maintaining structural integrity. The maximum Von Mises stress was found as approximately one quarter of the yield strength of the frame material. The maximum total deformation was achieved below 0.3 mm, and deformation under 1 mm is considered safe in the literature. As a result, the optimized design offers a lighter drone structure in line with conventional manufacturing methods, providing better flight time and payload capacity while maintaining cost effectiveness. In future studies, comparisons can be made based on this study by performing weight optimizations suitable for current methods such as topology optimization or generative design. The cost factor and the availability of existing production lines should be taken into consideration when comparing the mentioned methods with parametric optimization.

Материал и методы:в период с января 2019 года по апрель 2019 года структурированный опросник по СГХС, включавший вопросы распространенности, наследуемости и диагностики СГХС, сопутствующего ей сердечно-сосудистого риска,тактики ведения больных СГХС, анонимно заполнялся врачами разных специальностей лечебно-профилактических учреждений Волгоградской, Ростовской области и Республики Калмыкия. Результаты:из 184 опрошенных врачей, 40 были осведомлены о наследуемости СГХС, 31 - о ее распространенности. Уровень сердечнососудистого риска, связанный с СГХС, правильно указали только 5 специалистов,а правильный возрастной порог преждевременной ИБС у мужчин - 10. Большинство опрошенных указали в качестве наиболее эффективных диагностов СГХС кардиологов и генетиков. Среди мер по улучшению качества первичной профилактики СГХС 42 врачей предпочли комментарий к биохимическому анализу, указывающий на гиперхолестеринемию. О вариантах лечения больных СГХСв виде монотерапии статинами осведомлены 67 опрошенных, ав виде комбинации статина и эзетемиба 42. Также только 37 врачей знают специалистов по СГХС в близлежащем районе. Выводы:осведомленность врачей в области СГХС оказалась недостаточной, но не имела статистически значимой взаимосвязи с демографическими и трудовыми параметрами.Имплементация национальных рекомендаций по СГХС и увеличение осведомленности по СГХС врачей разных специальностей могут быть основой для улучшения первичной помощи больным СГХС.
