Published: February 2025

Low-carbon tourism, as a new form. of tourism that adapts to the development of the times, which has received widespread attention from domestic and international scholars in recent years. Based on the Theory of Planned Behavior. and the ABC Theory of Attitude, this study establishes a cognitive behavior. model of low-carbon tourism for young tourists. Through questionnaire surveys and analysis, it discusses the relationship between young tourists' cognition, attitude, and behavioral intention of young tourists in Beijing Botanical Garden towards low-carbon tourism. The research findings indicate that: Firstly, young tourists generally have a high level of cognition about low-carbon tourism, recognizing the impact of tourism activities on carbon emissions and the importance of low-carbon tourism for environmental protection. Secondly, subjective norms, positive attitudes towards low-carbon tourism, and perceived behavioral control all have a significant positive impact on young tourists' behavioral intentions towards low-carbon tourism. Thirdly, awareness of low-carbon tourism also directly positively influences behavioral intentions, further emphasizing the importance of enhancing awareness in promoting low-carbon tourism. Based on these findings, this paper proposes counter measures to encourage young tourists to engage in low-carbon tourism: governments, tourism enterprises, and social organizations should jointly conduct promotional activities to raise youth awareness; create a low-carbon tourism environment and improve facilities; and strengthen social norms to foster positive attitudes

Comprehensively advancing the integration of ideological and political education within curricula represents a pivotal strategy in the reform. of higher education curricula. The urgent necessity lies in exploring viable pathways for ideological and political education within undergraduate practical courses. “Hydrology Fieldwork” stands as a mandatory practical course for disciplines like Geographic Science, as well as Resource and Environmental Science. Rooted in regional characteristics and aligned with professional training objectives, the ideological and political education embedded in hydrology fieldwork should be grounded in the principles of hydrology and water resources science. Drawing from a resource repository encompassing hydrological pioneers, projects, events, and culture, this educational endeavor delves deeply into various facets, including scientific attitude and innovative spirit, patriotism, confidence in the socialist system, social responsibility, a sense of pride in water culture, the concept of sustainable development, and the contemporary hydrological spirit of “science, realism, and innovation. ” Such an approach necessitates the revision of the concepts, connotations, and models associated with ideological and political education for talent cultivation. It also aims to augment the warmth, depth, breadth, and efficacy of ideological and political integration within curricula, ultimately achieving the dual objectives of enhancing practical skill training and fostering ideological and political awareness.

In this project, we're taking on the task of creating an Android college attendance system, which will utilize facial recognition, location tracking via Google Maps API (GMAP), and, optionally, bio verification for attendance in classrooms. The system guarantees that only the students, themselves physically present at the respective classrooms, will be able to mark their attendance, thereby providing security and ensuring the integrity of attendance records. The application has been developed primarily in Java and XML on the front end and uses Firebase Authentication and Real-time Database on the backend.
The three user types supported by the system are students, teachers, and parents. Along with facial recognition and verification based on location, it could also consist of biometrics such as fingerprint scanning to increase security. Parents will get real-time updates about where their children are, students can check attendance records, and teachers share news about attendance. Therefore, it will automate attendance with additional real-time communications to parents
How Qi Became Energy
Authors: Baum Emily
Published: February 2025

Qi has long been a thorny concept, presenting both translational and conceptual difficulties for scholars working within and beyond Asia. In English today, qi is most often translated as ‘vital energy’, but this was not always the case. This chapter focuses on one moment in the conceptual transformation of qi into energy. In the 1970s, a group of parapsychologists in the United States and Russia began to use Kirlian photography to document so-called ‘energy flows’ within organic matter, an undertaking that coincided with the rising global interest in acupuncture. This unlikely convergence of phenomena reinforced the correlation between energy and qi, a definition that has become the normative interpretation of qi today.
Finding Kyo in Shiatsu Spaces
Authors: Skrivanic Peter
Published: February 2025

This chapter utilises ethnographic engagements with practitioners of shiatsu, a form of manual therapy developed in Japan in the 20th century, to shed light on two issues relevant to the study of globalised East Asian spiritualities and therapies. First, it adopts a ‘worlding’ approach within the author’s multi-sited, transnational field site, as a way of mapping the spatiality of global movements of ideas and practices without utilising and reinforcing dichotomies such as East/West, while nonetheless attending to how such notions can remain salient within informants’ discourses and imaginaries. Second, by attending to the sensory dimensions of knowledge translation in shiatsu diagnostic practices, the study models one way for scholars of globalised East Asian spiritualities and health movements to engage with underexplored dimensions of how such knowledge practices work on and through the local minds and bodies who carry them into new environments.
Capturing the Moment of Kimochi-ii
Authors: Xinzhe Huang
Published: February 2025

This paper focuses on the practice of qigong and aims to analyse its localisation and transformation in contemporary Japan. Instead of solely examining how qigong’s theories and knowledge originated in China and were adapted to the Japanese context, this chapter highlights the significance of bodily experiences, including affect, senses, and imagination, to describe the generation and transformation of specific feelings during Japanese qigong classes. When discussing ‘transnational qigong’, I suggest that it is also crucial to consider how the sharing, generation, and transformation of sensory and affective experiences through qigong practice preserves its vitality in the local context and constructs a local qigong culture.
Language Ideologies and Cultural Security: The Status and Meanings of the Uyghur Language1
Authors: Cabras Giulia
Published: February 2025

As one of the official languages of Xinjiang and the official language of the Uyghurs, Uyghur has spread across various domains of the public sphere and has become a symbol of cultural autonomy. While China guarantees the legal status and freedom of officially recognized ethnic minority languages to be developed and used in the public sphere, government language policy has intensely promoted Standard Chinese, particularly in the education sector. This chapter covers the years from mid-2000 to 2017 and addresses how language ideologies of an “authentic” and “pure” Uyghur have been seen as a tool to protect the language and how the discourse on bilingualism has been used as a way to guarantee social and economic integration for the group. Finally, it assesses the extent to which the language is an important element in defining group consciousness among Uyghurs in light of the current policies of re-education and assimilation.
proposed AHP-SERVQUAL model for hotel service quality Management
Authors: Kheddache Fares , Djadli Samir
Published: February 2025

This study proposes an AHP-SERVQUAL model to evaluate service quality in the Algerian hotel industry, emphasizing the gap between customer expectations and managerial perceptions. The research involved four hotels in Constantine, Algeria, and analysed responses from 12 managers and 77 customers. Utilizing the SERVQUAL dimensions—tangibility, reliability, assurance, empathy, and responsiveness—this study examines 19 selection criteria, weighted through the Analytic Hierarchy Process (AHP). The findings reveal significant discrepancies: managers overestimate tangibility and reliability, while underestimating empathy, responsiveness, and assurance. In contrast to the managerial focus on tangibility, the responsiveness dimension is valued most by customers. This misalignment highlights the need for managerial strategies that align better with customer priorities to enhance service quality and competitiveness. This study contributes to the literature by integrating AHP with SERVQUAL, thereby offering insights into improving service delivery and customer satisfaction in the hospitality sector. Future research should explore broader geographic contexts and additional service dimensions to gain a more comprehensive understanding.

Published: February 2025

As the U.S. financial sector confronts evolving threats from financial crimes, the integration of Machine Learning (ML) and Deep Learning (DL) into Anti-Money Laundering (AML) strategies has become imperative. This paper explores the role of ML and DL technologies in enhancing AML frameworks to identify, mitigate, and prevent money laundering activities. The paper begins by analyzing prevalent money laundering schemes and the methods used by criminals to bypass traditional AML controls. The study underscores the importance of educating and training financial institution personnel to ensure the effective implementation of AML strategies powered by ML and DL. The findings revealed that a culture of awareness and accountability is vital for managing risks associated with financial crimes. Furthermore, the paper highlights the value of collaboration and information-sharing between financial institutions, regulatory bodies, and technology providers. Industry partnerships, public-private initiatives, and shared threat intelligence are identified as key components in strengthening AML defenses. This research also examines the transformative potential of ML and DL in AML. It shows how these technologies enhance pattern recognition, anomaly detection, and decision-making processes, allowing financial institutions to stay ahead of evolving money laundering tactics. Moreover, the dynamic and self-learning capabilities of ML and DL models enable continuous adaptation to new risks. Through adaptation of a vigilant, collaborative, and technology-driven approach, U.S. financial institutions can leverage ML and DL to enhance AML frameworks, safeguard consumer trust, and protect the integrity of the financial system.

Information Systems Function Architecture – A Brief Review
Authors: VELOSO Márcia
Published: February 2025

Information Technology (IT) and Information Systems (IS) are vital organizational resources. IT/IS help organizations to effectively respond to evolving business needs and emerging opportunities, enhancing competitiveness. A capable organizational IS Function is necessary to effectively tackle the current challenges and responsibilities of the IT/IS. The IS Function is made up of several components that must be organized through a structured representation to facilitate their understanding. This paper reviews and discusses the IS Function Architecture as a valuable management tool for organizing IS Function elements and providing a holistic view of its reality. The findings indicate that the architecture of the IS Function must be tailored to the unique reality of each organization, as no two architectures are identical. As the architecture helps to deal with the complexity of the IS Function, facilitating its understanding through an organized structure that supports the identification of development opportunities, it is essential to keep it up to date to reflect the current IS Function.

Published: February 2025

Abstract. Brown carbon aerosol (BrC) is a major contributor to atmospheric air pollution in Europe, especially in winter. Therefore, we studied the chemical composition, diurnal variation, and sources of BrC from 17 February to 16 March 2021 at a rural location in southwest Germany. In total, 178 potential BrC molecules (including 7 nitro aromatic compounds, NACs) were identified in the particle phase comprising on average 83 ± 44 ng m−3, and 31 potential BrC (including 4 NACs) molecules were identified in the gas phase contributing on average 8.5 ± 6.7 ng m−3 during the whole campaign. The average light absorption of seven NACs in the particle phase was 0.2 ± 0.2 Mm−1, contributing to 2.2 ± 2.1 % of total BrC absorption at 370 nm. In addition, diurnal variations show that gas-phase BrC was higher in the daytime and lower at night. It was mainly controlled by secondary formation (e.g. photooxidation) and particle-to-gas partitioning. Correspondingly, the particle-phase BrC was lower in the daytime and higher at night. Secondary formation dominates the particle-phase BrC with 61 ± 21 %, while 39 ± 21 % originated from biomass burning. Furthermore, the particle-phase BrC showed decreasing light absorption due to photochemical ageing. This study extends the current understanding of real-time behaviours of brown carbon aerosol in the gas and particle phase at a location characteristic of central Europe.

Abstract. All hydrocarbon (HC) reservoirs leak to some extent. When small quantities of HCs escape offshore reservoirs and migrate through overlying organic-poor marine sediments towards the surface, these HCs are often completely metabolized by microorganisms before reaching the sediment–water interface. However, these low and often unnoticed upward HC fluxes still influence the geochemistry of surrounding sediments and potentially stimulate metabolic activity by microbial populations in shallow subseafloor environments. In this study, we examined how localized HC seepage affects microbial sulfate reduction in organic-poor sediments from the SW Barents Sea, focusing on three sampling areas overlying known HC deposits and two pristine seabed reference areas. The analysis of 50 gravity cores revealed significant variability in the predicted sulfate depletion depth, ranging from 3 to 12 m below the seafloor. We observed nearly linear pore water sulfate and alkalinity profiles, alongside low rates of sulfate reduction (pmol cm3 d−1). Metagenomic and metatranscriptomic data indicated metabolic potential and activity towards sulfate reduction and anaerobic oxidation of methane (AOM). Expression of functional marker genes (aprAB, dsrAB, mcrA) revealed metabolic activities by sulfate-reducing Desulfobacterota and methanotrophic ANME-1 archaea sustained by HC traces in the sediment. Furthermore, in concomitance to AOM processes, we found that archaea amongst the classes Lokiarchaeia and Thorarchaeia were expressing genes involved in sulfur reduction (hydB, hydG). Overall, our study demonstrates that the gradient in pore water geochemistry, the rates of sulfate reduction processes, and the genetic features of microbial populations actively involved in sulfate-driven AOM processes are all affected by low and often unnoticed upward HC fluxes. This slight HC seepage resulted in sulfate depletion at shallower depths compared to what would be expected at a comparable non-affected site and produced concomitant biogeochemical signatures in the shallow subsurface that enable the inference of deeply buried reservoirs.
An elucidatory model of oxygen's partial pressure inside substomatal cavities
Authors: Kowalski Andrew S.
Published: February 2025

Abstract. A parsimonious model based on Dalton's law reveals substomatal cavities to be dilute in oxygen (O2), despite photosynthetic O2 production. Transpiration elevates the partial pressure of water vapour but counteractively depresses the partial pressures of dry air's components – proportionally including O2 – preserving cavity pressurization that is negligible as regards air composition. Suppression of O2 by humidification overwhelms photosynthetic enrichment, reducing the O2 molar fraction inside cool or warm leaves by hundreds or thousands of parts per million. This elucidates the mechanisms that realize O2 transport: diffusion cannot account for up-gradient conveyance of O2 from dilute cavities through stomata to the more aerobic atmosphere. Rather, leaf O2 emissions depend on non-diffusive transport via mass flow forced by cavity pressurization, which is not negligible in the context of dynamics. Non-diffusive O2 expulsion overcomes massive inward O2 diffusion to force net O2 emission. At very high leaf temperatures, mass flow also influences transport of water vapour and carbon dioxide, physically decoupling their exchanges and reducing water-use efficiency, independently of stomatal regulation.

Published: February 2025

Abstract. Precipitation is a critical driver of the water cycle, profoundly influencing water resources, agricultural productivity, and natural disasters. However, existing gridded precipitation datasets exhibit markable deficiencies in capturing the spatiotemporal and physical correlations of precipitation, which limits their accuracy, particularly in regions with sparse meteorological stations. Therefore, this study proposes a completely new gridded precipitation generation scheme to address these issues. The long-term daily observation from 3,476 gauges and incorporated 11 related precipitation variables were utilized to characterize the correlations of precipitation. By employing an improved inverse distance weighting method combined with the machine learning-based light gradient boosting machine (LGBM) algorithm, a new high-precision, long-term, daily gridded precipitation dataset for mainland China (CHM_PRE V2) was developed, which aims to improve upon and surpass the CHM_PRE V1 dataset, developed in our previous work. Validation against 63,397 high-density gauges demonstrated that CHM_PRE V2 significantly outperforms existing datasets, achieving a mean absolute error of 1.48 mm/day and a Kling-Gupta efficiency of 0.88, representing improvements of 12.84 % and 12.86 %, respectively, compared to the previously optimal dataset. Regarding precipitation event detection, CHM_PRE V2 achieved a Heidke skill score of 0.68 and a false alarm ratio of 0.24, surpassing other datasets by 17.24 % and 29.17 %, respectively. Feature importance analysis revealed that spatiotemporal and physical correlations contributed 37.10 %, 34.11 %, and 28.78 % to precipitation retrieval, underscoring the necessity of incorporating temporal and physical correlations. CHM_PRE V2 markedly enhances precipitation measurement accuracy, reduces overestimation of precipitation events, and provides a reliable foundation for hydrological modelling and climate assessments. This dataset features a resolution of 0.1°, spans from 1960 to 2023, and will be updated annually. Free access to the dataset can be found at https://doi.org/10.5281/zenodo.14632157 (Hu and Miao, 2025).

Published: February 2025

Abstract. Various methods are available to measure water storage across different landscape compartments, e.g. cosmic-ray neutron sensing, remote sensing, or hydrogravimetry. All these methods provide integral estimates that are representative of their corresponding measurement volume. However, we typically do not know the true value of water storage in these measurement volumes, which makes it difficult to assess the accuracy of such methods. In this study we suggest a synthetic virtual landscape that allows for an exact definition of all variables of interest and, consequently, constitutes the so-called “virtual truth” free of knowledge gaps. Such a landscape can be explored in various “virtual field campaigns” using “virtual sensors” that mimic the response and characteristics of actual devices. We use dedicated physically based models to simulate the signal a sensor would receive. These model outputs, termed “virtual observations”, can be explored and also allow for the reconstruction of water storage, which can then readily be compared to the virtual truth. Insights from this comparison could help to better understand real measurements and their uncertainties and to challenge accepted knowledge about signal processing and data interpretation. The Virtual Joint Field Campaign is an open collaborative framework for constructing such landscapes. It comprises data and methods to create and combine different compartments of the landscape (e.g. atmosphere, soil, vegetation). The present study demonstrates virtual observations of water storage with cosmic-ray neutron sensing, hydrogravimetry, and remote sensing in three exemplary landscapes. It enables unprecedented opportunities for the systematic assessment of the sensor's strengths and weaknesses and even their combined use.

Published: February 2025

Abstract. Understanding how water vapor is transported to Antarctica and leads to snowfall is crucial for improving ice-sheet mass balance projections and interpreting ice-core records. Global navigation satellite system (GNSS) receivers distributed across Antarctica to monitor ice velocity and solid Earth motion can be used to understand accumulation, ablation, and snow redistribution at the ice-sheet surface on sub-daily timescales. Here, we present a forward model for reflector height change between the GNSS antenna phase center and the snow surface and an inverse framework to determine accumulation rate and near-surface firn densification from the reflector height time series. We use this model to determine accumulation at three long-term GNSS sites located in the Amundsen Sea Embayment (ASE) and at an array of GNSS receivers deployed in the 2007–2008 and 2008–2009 austral summers. From the GNSS interferometric reflectometry (IR) accumulation time series, we find that extreme precipitation (i.e., the 90th percentile of accumulation events) dominates total precipitation and that extreme event frequency varies seasonally. We use our GNSS-IR accumulation time series together with reanalysis products to characterize the atmospheric conditions that promote extreme snowfall in the ASE. The blocking pressure systems that promote extreme accumulation on Thwaites Glacier are facilitated by tropical teleconnections, specifically convection that promotes Rossby wave trains from the western Pacific, Indian, and Atlantic oceans to the Amundsen and Bellingshausen seas.

Authors: Klatt Stefanie , Bea Lisa-Marie , Brückner Sebastian , Jungen André , Noël Benjamin , Strauss Bernd
Published: February 2025

Effective decision making and communication are essential skills for sports officials, who frequently report experiencing considerable stress across various sports. This study evaluated the impact of a stress management program on elite volleyball referees. The intervention aimed to reduce stress and anxiety while enhancing coping strategies. Thirty-eight referees (24 males, 14 females) participated in a randomized intervention guided by two experienced applied sport psychologists. Stress and physiological measures were assessed before and after officiating. Anxiety and officiating-related stress were evaluated using the State-Trait-Anxiety Inventory (STAI) and an adapted version of the Basketball Officials Source of Stress Survey (BOSSS-d), respectively. Cardiac responses, including heart rate (HR) and heart rate variability (HRV), were monitored during games. The program’s effectiveness was assessed using the Inventory of Quality Sport Psychological Support (QS17). Although the pre- and post-intervention comparisons did not reveal significant changes in anxiety, reported sources of officiating-related stress, or cardiac responses, findings from the QS17 indicated potential benefits of the stress management program for elite volleyball referees, highlighting avenues for sport psychological support and interventions. Future research, particularly longitudinal studies, is needed to further explore referees’ stress experiences during officiating.

Influence of NGO's on the Control of Early Marriage in Borno State (2018-2022)
Authors: O. O. Gbadebo, , O. Akande,
Published: February 2025

Being a social problem, this research thus scoped its analysis on how Non-Governmental Organizations (NGOs) have been fighting early marriage in Borno State, Nigeria within the period 2018 to 2022. Child marriage is common in the region and is fueled by poverty, tradition and Boko Haram. These factors as well as the low implementation of protective laws are a violation of human rights and puts young girls at the mercy of gender-based violence, health risks and educational exclusion. This research uses an evaluation design in a case study of four NGOs to assess the interventions made. Results were obtained from structured questionnaires and interviews: gender equality promotion programs; school-based programs; community mobilisation programs; and media advocacy. Research findings establish that these multi-sectoral strategies have had direct positive impacts on awareness creation and early marriage, to a small degree. Despite these promising tools, cultural resistance, funding constraints and insecurity limit their efficiency. Specifically, the study finds that there is a dire need to increase the implementation of policies, involve traditional/religious leaders in programs, and revive antipoverty campaigns for education. Future research has to centre program evaluations for the long term and discuss displacement, for instance, as an intersectional concept. A closer look at these gaps will help stakeholders to develop better and more effective measures for ending early marriage in conflict-prone areas.

as crescentes modificações no mundo trabalho culminaram em um modelo de trabalho organizado por meio de plataformas digitais nas quais os trabalhadores oferecem serviços e são acionados por empregadores sem que haja vínculo, estabilidade ou direitos trabalhistas, cuja situação de precarização tem mostrado graves consequências para a saúde: o trabalho plataformizado. Objetivo: contextualizar e discutir aspectos característicos do trabalho plataformizado com foco no papel da enfermagem em promover saúde desses trabalhadores. Métodos: revisão da literatura que culminou na apresentação de três eixos de análise e reflexão: Os fundamentos teóricos necessários para uma reflexão crítica acerca das novas organizações de trabalho do neoliberalismo; O trabalho plataformizado e riscos de acidentes e adoecimento; Contribuição da enfermagem para promoção da saúde do trabalhador plataformizado. Resultados: Esse redesenho dos processos de trabalho, pode levar a sérios problemas psicossociais. Conclusão: Os profissionais de enfermagem devem atuar com enfoque integrado que aborde tanto a saúde física quanto a mental para a promoção do bem-estar geral dos trabalhadores, criando um ambiente de trabalho mais equilibrado e sustentável.

Published: February 2025

Let $K_{m\pm}=\mathbb{Q}(\sqrt[3]{m^3\pm1})$ be a pure cubic number field. We prove that the class number of $K_{m\pm}$ is a multiple of $3$ for $m\geq2$ and we find the fundamental unit of $K_{m\pm}$.
Fixed point theorems for generalized weak integral contractive condition
Authors: Kavita  , Kumar Sanjay
Published: February 2025

In the present work, we establish the existence of common fixed points for pairs of subsequential continuous mappings and variants of sequential continuous mappings as well as variants of R−weak commuting mappings, non-compatible and faintly compatible mappings satisfying a generalized ()-weak integral contractive condition involving cubic terms of distance functions. We also discuss the existence and uniqueness of common solution for a system of functional equations arising in the dynamic programming.

Published: February 2025

In this article, a new operation on product fuzzy graphs (PFGs) is provide; namely α-product. Conditions for the α-product of two PFGs to be strong are provided and we prove if the α-product of two PFGs is complete, then one of them is strong. We also study the unbiased notion of the class of PFGs and also conditions for the α-product to be unbiased are given.

Background: Antiandrogens such as Flutamide and Bicalutamide are commonly used in treating prostate cancer and other androgen-related conditions. However, their impact on cardiac health remains inadequately explored. This study aims to investigate the cardiovascular effects of these antiandrogens in adult male Wistar rats, focusing on cardiac biomarkers, antioxidant enzyme levels, and oxidative stress indicators.
Methods: Adult male Wistar rats were divided into three groups: a control group and two treatment groups receiving 50 mg/kg Flutamide and 10 mg/kg Bicalutamide, respectively, for 21 days. Body weight changes, heart weight, and serum levels of cardiac biomarkers (LDH, cTn-I, CK-MB) were measured. Oxidative stress was assessed by measuring superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), and malondialdehyde (MDA) levels.
Results: Flutamide and Bicalutamide treatment resulted in a significant decrease in relative heart weight, with values of 0.43 ± 0.04 g for Flutamide and 0.45 ± 0.05 g for Bicalutamide compared to 0.61 ± 0.06 g in the control group. Weight gain was also significantly reduced, with percentages of 17.77 ± 0.99% for Flutamide and 12.82 ± 0.91% for Bicalutamide, while the control group had 25.47 ± 0.55%. Elevated cardiac biomarkers were observed, with cTn-I levels of 58.69 ± 0.52 ng/ml for Flutamide and 56.98 ± 0.54 ng/ml for Bicalutamide compared to 52.23 ± 1.72 ng/ml in controls. Additionally, CK-MB levels increased to 29.84 ± 0.47 ng/ml for Flutamide and 31.34 ± 0.52 ng/ml for Bicalutamide from 19.02 ± 1.54 ng/ml in the control group. Antioxidant levels (SOD, CAT, GSH) were significantly reduced, with SOD at 6.17 ± 0.07 U/mg protein for Flutamide and 5.70 ± 0.15 U/mg protein for Bicalutamide, and MDA levels were significantly elevated to 1.88 ± 0.06 U/mg and 1.99 ± 0.52 U/mg, respectively, compared to 0.94 ± 0.06 U/mg in controls.
Conclusion: The findings indicate that Flutamide and Bicalutamide exert significant adverse effects on cardiac health, leading to oxidative stress and myocardial damage. These results calls for careful cardiovascular monitoring and consideration of antioxidant co-therapy during long-term antiandrogen treatment to mitigate potential cardiac risks in patients undergoing such therapies.
Distance sensing in an embedded system

Published: February 2025

The Arduino is an electronic board open -source for the development of many projects and concepts of automated control through an open-source language called Arduino c where is programmed by Arduino IDE. The purpose of this research is to develop a module to measure the distance for any body by using the concept of the ultrasonic waves (that mean using pulse velocity).
The ultrasonic ranging module HC - SRO4 is used as a distance sensor for detecting any move by measuring distance between sensor and body surface. The system consists of sensor Arduino Uno, LCD, LEDS variable resistance (it is very important to adjust the screen brightness (LCD)), Breadboard, and Wires. We adjust the distance on less than (10 cm) or to whatever value we want.
Anybody approaching from the ultrasonic sensor, the buzzer is turn on with the red led and the LCD is display the distance on the screen and this distance is measured in (cm), and if this body is stay away from this sensor (ultrasonic sensor) the buzzer is turn off and the green led is turn on.
