Published: May 2024

Abstract. Synthetic Aperture Radar (SAR) holds significant potential for applications in crop monitoring and classification. Interferometric SAR (InSAR) coherence proves effective in monitoring crop growth. Currently, the coherence based on the maximum likelihood estimator is biased towards low coherence values. Therefore, the main aim of this work is to access the performance of Sentinel-1 time-series biased coherence and unbiased coherence in crop monitoring and classification. This study was conducted during the 2018 growing season (April-October) in Komoka, an agricultural region in southwestern Ontario, Canada, primarily cultivating three crops: soybean, corn, and winter wheat. To verify the ability of coherence to monitor crops, a linear correlation coefficient between temporal coherence and dual polarimetric radar vegetation index (DpRVI) was fitted. The results revealed a stable correlation between temporal coherence and DpRVI time-series, with the highest correlation observed for soybean (0.7 < R < 0.8), followed by wheat and corn. Notably, unbiased coherence of the VV channel exhibited the highest correlation (R > 0.75). In addition, we applied unbiased coherence to crop classification. The results show that unbiased coherence exhibits very promising classification performance, with the overall accuracy (84.83%) and kappa coefficient (0.76) of VV improved by 8.35% and 0.12, respectively, over biased coherence, and the overall accuracy (73.25%) and kappa coefficient (0.57) of VH improved by 7.56% and 0.14, respectively, over biased coherence, and all crop classification accuracies were also effectively improved. This study demonstrates the feasibility of coherence monitoring of crops and provides new insights in enhancing the higher separability of crops.

Published: May 2024

Abstract. Monitoring the deformation of long-span bridges is essential for assessing structural health and safety. The existing single-camera deformation measurement method is unable to meet the high-precision measurement requirement for the deformation of large-span bridges. This paper proposes a real-time deformation measurement method for the long-span bridge using multi-inertial camera system. The method is based on visual measurement which the target deformation is measured by multiple cameras. Meanwhile, inertial measurement is used to estimate the relative pose of the camera to compensate for camera motion errors. It is applied to the health monitoring system of a long-span bridge. The experimental results show that the method proposed in this paper is highly consistent with the hydrostatic leveling measurement, with a RMSE of 4.83mm. The method can accurately and real-time measure the deformation of large-span bridges with a promising engineering value.

Abstract. Ecological conservation and restoration of national land space is an important aspect for implementing the national ecological civilization strategy, and an important measure for establishing the national ecological security pattern and coordinating the systematic management of mountains, water, forests, fields, lakes, grass and sand. The identification of key areas for ecological conservation and restoration is a precondition to spatially and temporally laying out ecological conservation and restoration planning, which is crucial for the ecological conservation and restoration of national land space. Therefore, this paper considers Henan Province as the study area and carries the research and practice of identifying key areas for ecological conservation and restoration by integrating multi-source data and remote sensing time series analysis. Firstly, based on the Google Earth Engine (GEE) cloud platform and MOD13A1 data, the Mann-Kendall method is used to analyze the trend of time series NDVI in the study area from 2011 to 2020. Secondly, based on multi-source data such as meteorological, soil, topographic, net primary production (NPP), etc., an ecosystem health analysis and assessment based on ecosystem service trade-off and synergy is used to select ecological source. Finally, based on the results of time series NDVI analysis and ecological source selection, fusion analysis is used to identify key areas for ecological conservation and restoration. The results show that this proposed research framework not only considers the “static” ecosystem services and ecosystem health attributes, but also measures the “dynamic” ecosystem change trends. It can effectively identify key areas for ecological conservation and restoration in national space. The results of the study can provide technical support for the background survey, problem identification, planning and engineering layout of ecological conservation and restoration in the national land space.

Defending Race-Conscious Policy
Authors: Jones Jack
Published: May 2024

Beginning in the 1980s, a coalition of community groups, activists, and non-profits loosely referred to as the “environmental justice movement” campaigned to draw awareness to the disproportionate distribution of environmental burdens to low-income communities of color. These burdens cause severely negative health impacts, reduce property values (which in turn reduce generational wealth), and im-pact quality of life. Low-income communities of color also receive few-er environmental benefits, including parks and green space (which re-duces heat in urban areas) and access to healthy food. Climate change further threatens vulnerable communities by causing increased heat in already-overheated neighborhoods, more frequent and severe storms, and rising sea levels in coastal areas.
In 2019, New York State enacted the Climate Leadership and Com-munity Protection Act (CLCPA), an ambitious piece of legislation that creates a framework to reduce statewide greenhouse gas emissions and to invest in “disadvantaged communities” (DACs). The latter goal reflects the environmental justice movement’s success. The current set of criteria developed under the CLCPA to identify U.S. census tracts within New York as DACs considers, among a large set of factors, the racial and ethnic demographics of the tracts. While this approach re-flects the environmental justice movement’s values, it also makes the CLCPA vulnerable to a potential constitutional challenge. Drawing on decades of precedent from the U.S. Supreme Court in cases regarding affirmative action programs, a plaintiff might bring a case arguing that the New York State government is distributing benefits based onindividuals’ race or ethnicity, in violation of the Equal Protection Clause.
This Note examines the degree to which the CLCPA’s current DAC criteria are vulnerable to such a challenge, and sets forth how the state might argue that the DAC criteria do not violate the Equal Protection Clause. Specifically, this Note argues that the state could mount a strong argument at the outset that such a plaintiff cannot satisfy the requirements for standing. In the alternative, the state could argue that the criteria should not draw strict scrutiny because race and eth-nicity are relatively insignificant factors in a complex and context-sensitive process. If the criteria do draw strict scrutiny, the govern-ment could argue that it has a compelling interest in remedying the ef-fects of its past acts of racial discrimination, and that the criteria are narrowly tailored to this interest. And finally, the government could argue that even if the criteria are unconstitutional for considering race, the issue is severable, and the criteria can be easily amended to remove race and ethnicity.
The Effect of Cinnamon Bark Extract (Cinnamomum burmanii) on Blood Malondialdehyde (MDA) Levels in Hyperglycemia Rats
Authors: Perisnawati Pemi , Yerizel Eti , Alimudin Tofrizal
Published: May 2024

Hyperglycemia is a condition where blood glucose levels increase beyond normal limits. Hyperglycemia can induce oxidative stress conditions caused by an increase in free radicals and a reduction in endogenous antioxidant defenses, characterized by an increase in blood malondialdehyde levels. Oxidative stress causes malondialdehyde levels to increase and endogenous antioxidants to decrease, therefore the body needs exogenous antioxidants. One plant that is rich in antioxidants is cinnamon bark, where cinnamon bark can increase antioxidant capacity. This study aims to examine the effect of cinnamon bark extract (Cinnamomum burmanii) on reducing blood malondialdehyde levels in hyperglycemic rats. This research is experimental research using the Post Test-Only Control Group design. Male Wistar rats were divided into 5 groups (n=6), negative control (K-), positive control (K+), P1 (dose 100 mg/kgBW), P2 (dose 200 mg/kgBW), P3 (dose 300 mg/kgBW). The normality test was carried out using the Shapiro-Wilk test followed by One Way Anova and Kruskal Wallis. The results showed that cinnamon bark (Cinnamomum burmanii) was proven to be able to reduce blood malondialdehyde levels, where the optimal dose was P1 (dose 100mg/kgBW) whereas in the P1 group, the average malondialdehyde levels were found to be the lowest compared to other treatment groups.

The desire for unbiased journalism that effectively counters disinformation is widely recognised. News consumers are not only interested in news, but they also want unbiased journalism that cuts through disinformation, and they want it from trusted news sources. Consequently, media researchers need to explore ways to facilitate news-source identification, irrespective of the platform used. However, the availability of multimedia data sources has seen a remarkable surge in recent years, encompassing demographic data, social media data, geodata, and pervasive digital trace data. Multimedia data mining is a procedure of discovering stimulating trends via media data using video, text, and audio that are not generally available by simple enquiries and related outputs. Researchers face the challenge of integrating these diverse sources to enhance news source attribution in multimedia data including platforms like Facebook, WhatsApp and Instagram. The paper presents a review of multimedia data approaches and their application to news source attribution research. Also, the examination of the benefits and limitations of these techniques and discussion on future directions were mentioned. Consideration was on machine learning and statistical approaches to multimedia data, which include deep learning, and probabilistic modelling. Similarly, a discussion on the importance of data privacy and ethics in news source attribution research was stated. The contribution of this study is highly relevant for news media research groups striving to improve their capability to attribute sources in multimedia data, thereby combatting disinformation and amplifying trusted media brands.

Published: May 2024

A Growth in Indonesia is increasing and the energy sources needed by humans are also increasing. Therefore, more environmentally friendly and renewable energy sources are needed. One source of renewable energy is solar panels which use the sun as a source to produce electrical energy for human needs. Renewable energy that is now widely loved is solar energy, which can be converted into electrical energy with the help of solar panels. Solar panels are made of semiconductor silicon which absorbs photons from the sun's energy. However, the sun does not only produce photons which can be converted into electrical energy, but there is also heat energy which can increase the temperature of the solar panels which can reduce the performance of the solar panels. Therefor researchers conducted research to reduce the temperature of solar panels by using the monocrystalline solar panel cooling method using mineral oil with the immersion cooling technique. However, the solar panel itself has a maximum body temperature which affects the output of the solar panel. Solar cell panels experience a decrease in their ability to produce electricity if they get too hot or exceed their effectiveness limit. Therefore, a cooling system is needed to cool or reduce the temperature of the solar cell panels, so that they can produce electricity effectively and efficiently. If you look at the cooling process, solar cells remain good and stable at a temperature of 25ºC -35ºC because at this temperature the solar panels can produce the best power.

An induction motor is a motor that is difficult to control so it requires synchronous speed due to dynamic load changes which are controlled by the torque current while the field current is kept constant. Thus, in this paper, we implement an adaptive PID controller method with an induction motor using MATLAB which coordinates the speed of two decoupled loads with a three-phase induction motor, where an adaptive Self Tuning Regulator (STR) PID controller is designed and realized to regulate the speed of a three-phase induction motor. using MATLAB software and AVR Atmega16 microcontroller as input and output from the plant with communication using serial RS232. The results show that after coordinating the system with each motor which is given a neural controller and FOC, the motor speed results are obtained which gradually provide synchronous speed so it can be concluded that this system can work well to slow down the plant response.

ASSESSING THE IMPACT OF ENGINEERED WOOD PRODUCTS ON SUSTAINABLE CONSTRUCTION: A COMPARATIVE STUDY WITH CONVENTIONAL CONCRETE BUILDING METHODS
Authors: Fasasi M. O.
Published: May 2024

Renewable-sourced EWPs offer enhanced dimensional stability, durability, and mechanical properties, facilitating larger and more complex structural elements, and contributing to faster construction times and better energy performance. The research investigates the feasibility and effectiveness of Engineered Wood Products (EWPs) as sustainable building materials in the construction sector by a comparison of their cost, performance, and environmental impact against conventional concrete. The research emphasises the importance of innovative design, recycling, and waste reduction in fostering sustainable construction methods that satisfy the demands of present and future generations while conserving energy. However, there are negative environmental impacts linked to the production of concrete, such as habitat destruction, atmospheric emissions, and waste generation. The research adopted a web-based survey to gather quantitative data from construction experts. The Relative Importance Index (RII) was adopted to analyze the respondents' perceptions of the benefits of EWP and concrete negative effects. The results of the research reflect respondents' significant preference for EWPs and are consistent with their outstanding environmental qualities. In conclusion, this paper argues that EWPs possess the potential to effectively revolutionise the construction industry by minimising its carbon footprint and encouraging sustainable construction practices that are required for addressing the expectations of both the present and the future.
Use of Botulinum Toxin Type A in patients with Trigeminal Neuralgia
Authors: Prüsse Julya , Viana Fernando André Campos , Silva Bruno Frota Amora , Medeiros José Rômulo de
Published: May 2024

This article provides a systematic review of the efficacy of Botulinum Toxin Type A (TBA) in treating trigeminal neuralgia (TN), a painful disorder affecting the trigeminal nerve. TN is described in the literature as a facial pain of acute nature, often unilateral, characterized by episodes of intense and transient pain, comparable to electric shocks. The diagnosis is made through a detailed evaluation that includes anamnesis, characterization of symptoms, and imaging tests to exclude similar pathologies. Conventional therapy for TN involves the use of carbamazepine; however, in cases of pharmacological resistance or ineffectiveness of standard treatments, TBA emerges as a viable therapeutic alternative. The efficacy of TBA, as demonstrated in retrospective and prospective studies, is due to its ability to inhibit the release of neurotransmitters responsible for pain transmission and inflammatory processes. Various studies corroborate the efficacy of TBA, especially in patients over 50 years old, observing substantial improvement in symptoms with minimal adverse effects. The administration of TBA is carried out directly in the trigger zones, where it has proven to be well-tolerated, providing significant improvement in the quality of life of the affected patients. Despite promising results, the literature suggests the need for additional studies to optimize the dosage protocols and application of TBA, aiming to ensure its efficacy and safety in the long term. In conclusion, this article reiterates that TBA represents an effective and minimally invasive therapeutic alternative for the treatment of TN. However, it is essential to develop individualized therapeutic protocols and conduct more comprehensive studies to consolidate its use as the treatment of choice.

Authors: Owen Egharevba , Kooi Ong Siew , Ebhodaghe Okieimen Felix , Hilary Ifijen Ikhazuagbe
Published: May 2024

The aim of this study was to investigate the modifications of the mechanical properties of polypropylene (PP) by incorporating elastomers, while considering the impact on its stiffness. Specifically, the research focused on determining the optimal loading of elastomer to achieve desirable properties and exploring the influence of these processes on the morphology and mechanical behavior of the prepared blends. Thermoplastic elastomers (TPEs) consisting of polypropylene and natural rubber (PP/NR) were prepared using a melt-mixing process, and the mechanical properties of the blends were evaluated. The stress-strain properties of the blends revealed a successful modification of PP, transforming it from a stiff and strong thermoplastic into a stiff and tough thermoplastic elastomer when 10% NR was included in the PP matrix. As the loading of NR increased, a reduction in tensile strength (TS) and modulus (E) of the blends was observed, while elongation at break (EB) increased. The flexural strength of unmodified PP was 45.9 MPa, which decreased with increasing NR loading. Similarly, the impact strength of unmodified PP was 25.8 KJ/m2, whereas the values for 10%, 20%, 30%, and 40% NR inclusion were 30.8, 24.3, 20.6, and 15.2 KJ/m2, respectively. The melt flow index (MFI) of unmodified PP was 14.1 g/10 min, while the values for 10%, 20%, 30%, and 40% NR inclusion were 19.4, 15.7, 11.6, and 10.2 g/10 min, respectively. The best combination of mechanical properties was observed at 10% NR inclusion in the PP matrix. The micrograph of the blends, as observed from SEM micrographs, supported the modification of PP, resulting in the production of TPE with observable adhesion sites, indicating good compatibility between the components. In a nutshell, a significant 47% increase in impact strength was achieved through the modification process.
An overview of the anticancer activity of some mononuclear and polynuclear platinum(II) complexes
Authors: Giri Sheetal , Singh Ajay , Kumar K.
Published: May 2024

A famous cisplatin anticancer agent is one of the most widely used chemotherapeutics for treating several human solid tumors. Toxicity of the normal cell is a life-threatening issue that restricts the therapeutic potential of cisplatin complex as an anticancer drug. Even though every year thousands of cisplatin-based analogs have been prepared, screened, and reported, only very few compounds entered the medical trials. Hence, new research work is still sensible. In the last few years, many mononuclear and polynuclear platinum complexes have been considerably investigated, in vitro and in vivo studies evaluated, with some compounds demonstrating significant anticancer potential. In this review, various mono-metallic and poly-metallic platinum‐based complexes with various derivatives used as ligands that have anticancer potential are defined and numerous typical examples are discussed briefly. Present investigation, numerous mononuclear cisplatin derivatives exhibited greater anticancer potency than the parent cisplatin drug.

Quality and safety of drugs are essential for effective therapeutic performance. Impurities can compromise the quality and safety of drugs, and they can arise during various stages of the development, production, storage and even transportation process. Therefore, detecting and measuring the number of impurities with high accuracy in drugs is necessary to ensure the quality and safety of drugs and to reduce the risks associated with taking them. Detecting and measuring impurities in drugs require advanced analytical techniques. The review highpoints a variety of analytical chemistry techniques include spectrophotometric and chromatographic methods in addition to some electrochemistry methods that have been applied for determination of certain drugs such as Ciprofloxacin, Metronidazole, Hydroxychloroquine and Cefotaxime in their pure form, combined form with other drugs, combined form with degradation products, and in biological fluids.
Buckminsterfullerene fragments used as hydrogen carrier: Case of corannulene derivatives
Authors: Derrar Siham Naima , Rafai Ossama
Published: May 2024

Buckminsterfullerene fragments are interesting to use in hydrogen adsorption because of the suitable properties possessed by their concave structure. In the present paper, adsorption of hydrogen on the bowl-shaped corannulene and its derivatives is investigated. Both electron donor and electron acceptor are explored in the substitution and 28 derivatives are generated. DFT calculations are performed by means of WB97XD functional. The substitution number and the substitution nature of corannulene derivatives are analyzed through results based on several parameters. Besides bowl depth and equilibrium distance, also charge distribution and some reactivity indices, based on MEDT, are reported. Results show that a newly created charge distribution contributes to a better binding process.
Examination of the Activities in the 5th Grade Turkish Course Book in Terms of Digital Competence
Authors: Kır Durmuş Barış
Published: May 2024

In this study, the activities in 5th grade Turkish textbook were examined in terms of digital competence. The case study design, one of the qualitative research designs, was used in the research. In this context, an attempt was made to reveal the adequacy of the activities in the textbook in terms of digital competence. For this purpose, a list of criteria was created by the researcher. The data was obtained through document analysis using the criteria list from the activities in this textbook. Descriptive analysis technique was used to interpret the data. As a result of the findings obtained from the analysis of the data, it was determined that examined only 10 of the 329 activities and 41 of the 128 preparatory studies were capable of measuring digital competence. Although 32 percent of the preparatory studies fill the gap of activities in terms of directing students to internet resources, it has been determined that they mostly measure the "access to information" item, while other items are measured very little or not at all. Since access to information alone will not be sufficient to gain digital competence, it has been concluded that the activities in this textbook are not sufficient in terms of digital competence.
Institutional and Popular Religion in Quevedo’s “Ya la obscura y negra noche”
Authors: Czepiel Maria
Published: May 2024

This study demonstrates the complex relationships between institutional religion and local, popular devotion in Quevedo’s poem “Ya la obscura y negra noche.” Through the application of the figure of Wisdom to Mary, Quevedo uses knowledge of liturgy and Scripture to dignify the local advocation of the church of Santa María de la Antigua in Valladolid. It also explores how this figure’s address to the local cofrades and encouragement of confraternal celebration uses orthodox scriptural interpretation to privilege popular devotion over institutional religion.
