Quantifying particulate matter optical properties and flow rate in industrial stack plumes from PRISMA hyperspectral imager
Authors: Calassou Gabriel , Foucher Pierre-Yves , Leon Jean-Francois
Published: September 2023

Abstract. Industrial activities such as metallurgy, coal and oil combustion, cement production and petrochemistry release aerosol particles into the atmosphere. We propose to analyze the aerosol composition of plumes emitted by different industrial stacks using PRISMA (PRecursore IperSpettrale della Missione Applicativa) satellite hyperspectral observations. Three industrial sites have been observed: a coal-fired power plant in Matla, South Africa (imaged on September 25, 2021), a steel plant in Wuhan, China (March 24, 2021), and gas flaring at an oil extraction site in Hassi Messaoud, Algeria (July 9, 2021). Below-plume surface reflectances are constrained using a combination of PRISMA and Sentinel-2/MSI images. The radiative transfer simulations are performed for each scene including the surface, background atmosphere, and plume optical properties. The plume aerosol optical thickness (AOT), particle radius, volume of coarse mode aerosol and soot are then retrieved within the plumes following an optimal estimation framework. The mean plume retrieved AOT at 500 nm ranges between 0.27 and 1.27 and the median radius between 0.10 μm and 0.12 μm. We found a volume fraction of soot of 3.6 % and 10.4 % in the sinter plant and coal-fired plant plumes, respectively. The mass flow rate of particulate matter at point source estimated by an integrated mass enhancement method varies from 511 g s-1 for the flaring emission to 1401 g s-1 at the coal-fired plant.

Published: September 2023

Abstract. High Ozone Production Rate (OPR) leads to O3 pollution episodes and adverse human health outcomes. Discrepancies between OPR observation (Obs-OPR) and OPR modeling (Mod-OPR) as calculated from observed and modeled peroxy radical and nitrogen oxides reminds of a yet-perfect understanding of O3 photochemistry. Direct measurement of OPR (Mea-OPR) by a twin-chamber system emerges with the optimization required for suppressing the wall effect. Herein, we minimized the chamber surface area to volume ratio (S/V) to 9.8 m−1 and the dark uptake coefficient of O3 to the order of 10−9. Condition experiments further revealed a photo-enhanced O3 uptake and recommended an essential correction. We finally characterized a measurement uncertainty of ±27 % and a detection limit of 2.8 ppbv h−1 (3SD), which suggests that Mea-OPR is sensitive enough to measure OPR in urban or suburban environments. Application of this system in urban Beijing during the Winter Olympic Games recorded a noontime OPR of 7.4 (±3.8, 1SD) ppbv h−1, which indicates fairly active O3 photochemistry despite the pollution control policy implemented. Mea-OPR versus j(O1D) slope of 6.1 × 105 ppbv h−1 s−1 confirmed fairly active O3 photochemistry, which was assisted by a high abundance of VOCs and NOx, atypically high Mea-OPR even under high-NOx conditions, but mediated by relatively weak ultraviolet (UV) radiation.
Hypoxia also occurs in small highly turbid estuaries: the example of the Charente (Bay of Biscay)
Authors: Schmidt Sabine , Diallo Ibrahima I.
Published: September 2023

Abstract. The French coast facing the Bay of Biscay (north-east Atlantic) is characterised by the presence of small macrotidal and turbid estuaries, including the Charente, geographically located between the two large estuaries of the Gironde and the Loire (south-west France). Multi-year, multi-site, high-frequency water quality surveys have shown that the Loire, and to a lesser extent the Gironde, suffer from summer hypoxia. These observations raised the question of the possible occurrence of hypoxia, particularly in one of these small estuaries, the Charente, which flows into the Bay of Marennes-Oléron, the first oyster-producing area in France. Unlike its two large neighbours, the Charente estuary is not continuously monitored, although it is subject to similar climatic changes and anthropogenic pressures, making it impossible to assess potential risks to the ecosystem. Here we present a first investigation of dissolved oxygen in the Charente estuary, based on a combination of longitudinal studies along the estuary axis and instrumented sites to determine the intensity and spatial extent of deoxygenation. Oxygen and salinity sensors were deployed at several sites during the summers of 2018, 2019 and 2020 to record temperature, salinity and dissolved oxygen every 15 minutes. This high-frequency dataset will be compared with a long-term low-frequency dataset (1975–2022) to determine whether or not there is a degradation of oxygenation in the Charente estuary. The high-frequency dataset shows a high variability of dissolved oxygen (DO), with a clear influence of tidal cycles. During summer, DO concentrations are often below 5 mg L-1, and sometimes even below 2 mg L-1, indicating the presence of a summer oxygen minimum zone with an extension of about 20–25 km. Temperature is the DO main controlling factor, limiting preventive management strategies and, in the context of global warming, raising questions about the long-term suitability of the estuarine conditions for community needs, in particular migratory fishes.
Influence of Lower Tropospheric Moisture on Local Soil Moisture-Precipitation Feedback over the U.S. Southern Great Plains

Published: September 2023

Abstract. Land-atmosphere coupling (LAC) has long been studied focusing on land surface and atmospheric boundary layer processes. However, the influence of lower tropospheric (LT) humidity on LAC remains largely unexplored. In this study, we use radiosonde observations from the U.S. Southern Great Plains (SGP) site and an entrained parcel buoyancy model to investigate the impact of LT humidity on LAC there during the warm season (May–September). We quantify the effect of LT humidity on convective buoyancy by measuring the difference between the 2–4 km vertically integrated buoyancy with and without the influence of background LT humidity. Our results show that, under dry soil conditions, anomalously high LT humidity is necessary to produce the buoyancy profiles required for afternoon precipitation events (APEs). These APEs under dry soil moisture cannot be explained by commonly used local land-atmosphere coupling indices such as the convective triggering potential/low-level humidity index (CTP/HILow), which do not account for the influence of the LT humidity. On the other hand, consideration of LT humidity is unnecessary to explain APEs under wet soil moisture conditions, suggesting the boundary layer moisture alone could be sufficient to generate the required buoyancy profiles. These findings highlight the need to consider the impact of LT humidity, which is often decoupled from the humidity near the surface and largely controlled by moisture transport, in understanding land-atmospheric feedbacks over dry soil conditions, especially during droughts or dry spells over the SGP.

Published: September 2023

No previous study has analyzed the impact of caffeine intake on prooxidant-antioxidant balance and muscle damage following resistance exercise. The aim of this study was to determine the effect of 3 mg/kg of caffeine on the number of repetitions and the prooxidant-antioxidant balance and muscle damage after a session of full-body resistance exercise. Ten resistance-trained men habituated to caffeine participated in a randomized, crossover and double-blind experiment. Each participant performed two identical resistance training sessions after the intake of 3 mg/kg of caffeine or a placebo. Blood was collected before and 60 min after substance intake, just after exercise, 60 minutes after exercise, and 24 hours after testing to evaluate the activity of antioxidant enzymes (superoxide dismutase, glutathione peroxidase, catalase), non-enzymatic antioxidants (reduced glutathione, uric acid) levels of oxidative stress markers (plasma malondialdehyde) and muscle damage markers (creatine kinase, lactate dehydrogenase). There were no significant differences between placebo and caffeine conditions in the total number of repetitions (180 ± 15 vs 185 ± 14 repetitions, respectively; p = 0.276; Effect size [ES] = 0.34), the total time under tension (757 ± 71 vs 766 ± 56 s, respectively; p = 0.709; ES = 0.14) or the rating of perceived exertion (13.8 ± 2.7 vs 14.7 ± 2.7 a.u., respectively; p = 0.212; ES = 0.32). Reduced glutathione concentration obtained 1 hour after exercise was higher with caffeine than with placebo (p = 0.047), without significant difference between conditions for any other prooxidant-oxidant or muscle damage marker at any time point (p > 0.050 for all). The oral intake of 3 mg/kg of caffeine by resistance-trained men habituated to caffeine did not enhance the number of repetitions during a medium load full-body resistance training session to failure and had a minimal impact on the prooxidant-antioxidant balance and muscle damage. The study was registered prospectively at ClinicalTrials.gov with the following ID: NCT05230303.
Acute and Long-Term Effects of Static Stretching on Muscle-Tendon Unit Stiffness: A Systematic Review and Meta-Analysis
Authors: Takeuchi Kosuke , Nakamura Masatoshi , Fukaya Taizan , Konrad Andreas , Mizuno Takamasa
Published: September 2023

Static stretching can increase the range of motion of a joint. Muscle-tendon unit stiffness (MTS) is potentially one of the main factors that influences the change in the range of motion after static stretching. However, to date, the effects of acute and long-term static stretching on MTS are not well understood. The purpose of this meta-analysis was to investigate the effects of acute and long-term static stretching training on MTS, in young healthy participants. PubMed, Web of Science, and EBSCO published before January 6, 2023, were searched and finally, 17 papers were included in the meta-analysis. Main meta-analysis was performed with a random-effect model and subgroup analyses, which included comparisons of sex (male vs. mixed sex and female) and muscle (hamstrings vs. plantar flexors) were also performed. Furthermore, a meta-regression was conducted to examine the effect of total stretching duration on MTS. For acute static stretching, the result of the meta-analysis showed a moderate decrease in MTS (effect size = -0.772, Z = -2.374, 95% confidence interval = -1.409 - -0.325, p = 0.018, I2 = 79.098). For long-term static stretching, there is no significant change in MTS (effect size = -0.608, Z = -1.761, 95% CI = -1.284 – 0.069, p = 0.078, I2 = 83.061). Subgroup analyses revealed no significant differences between sex (long-term, p = 0.209) or muscle (acute, p =0.295; long-term, p = 0.427). Moreover, there was a significant relationship between total stretching duration and MTS in acute static stretching (p = 0.011, R2 = 0.28), but not in long-term stretching (p = 0.085, R2 < 0.01). Whilst MTS decreased after acute static stretching, only a tendency of a decrease was seen after long-term stretching.

Las Conferencias de las Partes (COP) son encuentros entre representantes de gobiernos, organizaciones no gubernamentales y la sociedad civil, donde se discute y toman medidas concretas para reducir las emisiones de gases de efecto invernadero y mitigar los impactos del cambio climático. Además, permiten establecer políticas y mecanismos para apoyar a los países en desarrollo en su transición hacia economías resilientes a la crisis climática. A lo largo de la historia se han llevado a cabo 27 COP, dos de ellas han alcanzado hitos significativos como la adopción del Protocolo de Kyoto en 1997 y la firma del Acuerdo de París en el 2015. Sin duda, las COP y los Objetivos de Desarrollo Sostenible (ODS) están estrechamente relacionados en el marco de la agenda global para abordar los desafíos del cambio climático y lograr un desarrollo sostenible. Las COP brindan un marco para la toma de decisiones y la implementación de acciones climáticas, contribuyendo así a varios ODS; a su vez, las acciones para lograr los ODS pueden impulsar la acción climática y generar beneficios mutuos para la sostenibilidad global. Pese a ello, se requiere una acción urgente y colaborativa para enfrentar la crisis climática y sobre todo, garantizar la implementación efectiva de las medidas acordadas años atrás.

Published: September 2023

Creativity is a central trait of giftedness, making the assessment of creativity an essential endeavor. A socio-cultural perspective takes into account all aspects of the social environment in which creative products emerge and underscores the necessity of considering these aspects when assessing such products. Regarding gifted classroom as a socio-cultural context, this study aims to introduce a systemic approach to evaluating creativity in designs created by gifted students, considering the multimodal discourse practices within the classroom. A qualitative descriptive method was employed, involving 16 fifth-grade gifted students in the study. Data were collected through participant design of artifacts and analyzed using multimodal and semiotic richness analysis. The results indicate that the analyzed texts are predominantly rich in semiotic aspects and demonstrate the effectiveness of the evaluation tool in assessing creativity in designs based on the discourse nature of the gifted students' science classroom.

臺灣舞蹈家、編舞家何曉玫的作品不斷探究身體的極限，透過舞蹈創造出獨特的觀看場域，使身體成為一種有生命之影像。當肉身即是影像，舞蹈亦等同於由關節與肌肉啟動的蒙太奇。正是在此，一種獨特的舞蹈知覺得以被傳遞，身體亦將在觸與碰的邊界間被重新組構。本論文以《默島新樂園》（2017）與《極相林》（2018）兩部舞作之間的劇烈變化開始，將彼此之差異視作影像的多樣性生成，並聚焦於身體的視覺化，諸如身體與影像共舞、無可區分等狀態，甚至是肉身轉化為螢幕、景框或影格般的存有。匯聚著對於舞蹈的身體、影像技術、視覺藝術以及哲學思想等問題辯證，本文試圖將肉身與影像這一組原先對立的概念思考為一種共時創造，以極具生機的狀態思考舞蹈的當代性。

 

Taiwan dancer, choreographer Hsiao-Mei Ho’s works constantly explore the limits of the body and create unique viewing fields through dance, making the body become a living image. While the body is the image, dance is also equivalent to a montage of joints and muscles. In here, a unique perception of dance is transmitted and the body is reorganized between the boundaries of touch and being touched. This thesis starts with the dramatic changes between New Paradise of Silent Island (2017) and Renaissance of Its Ashes (2018), regarding the differences between the two dance works as diverse becoming of image, and focuses on the visualization of body, such as the indivisible status of dance with body and image, and even the mode of being that the flesh transformed into screen, frame, or photogram. The dialectics of dancing body, technics of image, visual arts and philosophical thoughts converge in this thesis attempting to consider the body and image, which were originally opposite concepts, as a kind of synchronic creation and think about the contemporaneity of dance in a very vital state.

Problem-based learning design thinking is a student-centered literacy-oriented teaching model. By using Practical Action Research, this study explores the teaching practices of integrating design thinking into cross-disciplinary aesthetic curriculum. The researchers led four teachers to develop a cross-disciplinary aesthetic curriculum using design thinking steps. The data were collected from questionnaire survey, teaching observation, student learning sheets and teaching reflection. The researchers found that: 1. The teaching practice of integrating design thinking into interdisciplinary aesthetic curriculum, includes four teaching processes: exploring beauty, selecting beauty, creating beauty, and seeing beauty. 2. The cross-disciplinary aesthetics curriculum was effective, showing the best ability in "Applied Technology" and the weaker ability in "Creative Design". 3. Integrating design thinking in teaching helps to enhance teachers’ professional competence, with ’guidance’ replacing ’leadership’ as a test of teaching ability. Finally, the researchers put forward three suggestions: 1. For different teaching objectives, the design thinking process should be flexibly adjusted. 2. The learning content of "Reflective Feedback" and "Innovative Design" should be strengthened. 3. Design thinking should be incorporated into school curricula, long-term planning and management. It is hoped that this study will provide helpful insights for educators in the field of education.

Published: September 2023

The world’s energy landscape is undergoing rapid transformation as societies strive towards renewable and sustainable power sources in response to the need for energy security and climate change. Depletion of fossil fuels and increasing focus on environmental sustainability have been significant drivers in this global shift towards renewables. Among the promising solutions, solar-wind hybrid energy systems have gained attention, capitalizing on the complementary nature of solar and wind resources. However, selecting the optimal site for these hybrid plants is crucial for their successful implementation and efficiency. This research introduces a comprehensive methodology for site selection, seamlessly integrating the Delphi method and Analytic Hierarchy Process (AHP). The Delphi method harnesses expert consensus to distil essential criteria, while AHP offers a structured framework to evaluate and prioritize these criteria. The results showed successful utilization of the AHP and Delphi techniques for evaluating the optimal location selection among different cities for solar-wind hybrid energy harnessing in the northwest region of Pakistan. The key factors for selection of optimal location were identified through expert feedback and analysis. Among the selected key main criteria, resource availability and infrastructure and socio-economic factors emerged as the top-ranked criteria in this study. The results of this study hold significant relevance and should be duly considered for solar-wind power project site selection, while also offering opportunities for further enhancements in the future.

Published: September 2023

Purpose-Over the past few years, more crowdsourcing sites have emerged and crowdsourcing users have been faced with more temptations, leading to a loss of users on some crowdsourcing sites. In order to retain crowdsourcing users, the aim of this paper is to explore the factors that influence the continued engagement behaviour of crowdsourcing participants. Design/methodology/approach-Based on Maslow's Hierarchy of Needs Theory and Expectation Confirmation Theory, this paper investigates the factors influencing the sustained participation behaviour of respondents, starting from their motivation and experience after initial participation. Based on this, we propose a hypothesis and a model, and use the Yippee Wizards platform as the research object, obtain questionnaire data in the form of task distribution and conduct an empirical test through SPSS. Findings-The results found that economic motivation was the most significant motivator for the recipient to engage in crowdsourcing activities, that belongingness and satisfaction mediated the chain between expectation confirmation and continued engagement behaviour, and that a higher user rating promoted the utility of belongingness on satisfaction. Originality/value-This empirical analysis demonstrates that the level of wizards moderates the relationship between belonging and satisfaction, and that the higher the level of wizards the greater the facilitation effect.

The Identified Legacy
Authors: Xiao Anji , Li Sipeng
Published: September 2023

This paper delves into the heritage preservation of the folk-art culture of the Tianqiao area in Beijing, known for its vibrant traditional drama. It argues that stamping a culture as ‘heritage’ suggests that it’s extinct, since it overlooks the continuous evolution of this culture. The concept of ‘heritagization’ is explored to illustrate the challenges and rewards of cultural preservation, suggesting that while it is crucial to preserve key aspects of culture, simplified representation or distortion must be avoided. As society modernizes, traditional art forms like the Tianqiao folk culture evolve and their original audience diminishes. This paper discusses the complex dynamics of culture, privilege, class, and socio-economic forces in contemporary society, arguing against the commodification of culture. It stresses the need for a recalibration of efforts towards preserving cultural heritage, bearing in mind the rapid pace of urbanization and economic development.

The Impact of Extreme Temperatures on Grain Production in the Huaihe River Basin
Authors: Jin Na , Guo Lijing
Published: September 2023

The Huaihe River Basin is an important major grain producing area in China, maintaining the stability of grain output is of great significance to food security. However, with global warming, the frequency of extreme temperature events has increased, and the frequent meteorological disasters have brought great challenges to the stable supply of food production. In this paper, the impact of extreme temperature on grain production in the Huaihe River Basin was analyzed by using the daily temperature and agricultural production related data of 28 prefecture-level cities in the Huaihe River Ecological Economic Belt from 2001 to 2020. The following conclusions are drawn: 1) The influence coefficient of extreme high temperature on grain production in the Huaihe River Basin is -0.021, extreme low temperature has no significant impact on food production. 2) The effects of extreme temperature on food production in different regions in the river basin were heterogeneous, but the overall impact was negative. The influence coefficients of extremely high temperature days on the eastern region and Midwest region were -0.035 and -0.052, respectively, while the influence coefficients of extremely low temperature days on the eastern region were -0.413. The results showed that the increase in the number of extremely high temperature days would reduce production in the eastern region andMidwest region of the basin, while the northern region was not significantly affected by extreme heat. The increase in the number of extremely low temperature days will reduce grain production in the eastern region, and the impact on the Midwest region and the northern region will not be significant. Based on the above conclusions, three suggestions are put forward to maintain the safety of food production in the Huaihe River Basin: 1) enhance the ability to detect climate change in the basin; 2) Protect the stability of grain cultivated land in the river basin; 3) Innovative breeding of climate-resilient food crop seeds.

Wireless Sensor Networks Overview
Authors: Wang Yuqiao
Published: September 2023

Wireless sensor networks have become widely used for their high accuracy, safety, and reliability, particularly in military applications where information is critical to victory. Chinese scholars have conducted research on wireless sensor technology, with the aim of reducing costs, meeting low power requirements, and adapting to environmental changes to enhance China's military strength. However, data transmission speeds are slower and signal strength weaker compared to wired networks due to physical and technical limitations, which may result in slower or even interrupted data and file transfer speeds. Despite these limitations, wireless sensor networks have played a critical role in China's reconnaissance system for collecting and processing information in the battlefield environment. The technical principles of wireless sensor networks involve a distributed sensing system with multiple nodes consisting of data collection, big data processing, information processing, and energy supply modules. The identification and tracking of battlefield targets rely on passive observation of objects in activity using acoustic vibration sensors. The development of wireless sensor networks is still ongoing, with problems including limited computing power, storage capacity, communication ability, and energy supply of sensor nodes, as well as the potential for information leakage during the transmission process.

Authors: Fu Yu , He Qinghui
Published: September 2023

The tensile strength of tight sandstone reservoirs has a direct impact on crack initiation, hydraulic fracture propagation, and the connectivity between hydraulic fractures and natural fractures during hydraulic fracturing processes. To overcome the limitations of experimental testing methods and field hydraulic fracturing techniques, this study conducted Brazilian tensile strength tests to obtain tensile strength data for 16 sets of tight sandstone samples. By comparing these experimental results with well logging data, a predictive model for the tensile strength of tight sandstone was established based on geophysical well logging data, with a correlation coefficient exceeding 0.92. The research findings indicate a positive correlation between tensile strength and sample density. This study provides support for fracture design, assesses fracturability, and aids in the selection of optimal drilling locations for hydraulic fracturing operations.
A Review of Prediction Methods for Permeability in Clastic Reservoirs
Authors: Fu Yu , Zhang Mingzhou
Published: September 2023

Accurate prediction of permeability in clastic reservoirs is of great significance for oil and gas exploration and development. This paper provides a comprehensive review of prediction methods for permeability in clastic reservoirs, including analytical methods, experimental testing, and numerical simulation. By comparing the three methods, it is found that the analytical method has the advantage of a theoretical basis and fast calculation speed, but the simplifying assumptions regarding reservoir structure may lead to inaccurate results. The experimental testing method directly measures the flow performance of rocks, but it is constrained by sample acquisition and experimental conditions. The numerical simulation method considers various influencing factors and simulates real reservoir conditions but requires extensive calculations and accurate parameter inputs. Future research can further develop the analytical method and numerical simulation method to improve prediction accuracy by incorporating actual data from experimental testing, leading to a more comprehensive and accurate prediction of permeability in clastic reservoirs.
