Published: March 2024

The current study describes the chemical composition, antifungal, antibiofilm, antibacterial and molecular docking studies of Syzygium dyerianum growing in Malaysia. The essential oil was obtained through hydrodistillation and characterized using gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). The antifungal and antibacterial activities were developed using the broth microdilution assay, whereas the effect on the microbial biofilms was determined using a semi-quantitative static biofilm assay. A total of 31 components were identified, which represent 99.5 % of the essential oil. The results revealed that the essential oil consisted mainly of β-pinene (15.6 %), α-terpineol (13.3 %), α-pinene (11.1 %), caryophyllene oxide (8.8 %), limonene (8.1 %), borneol (6.0 %) and viridiflorol (5.1 %). The results of the microdilution method showed that essential oil exhibited activity against Candida albicans and Streptococcus mutans with minimal inhibitory concentration values of 125 and 250 μg/mL, respectively. Furthermore, essential oil decreased the biofilm of C. albicans and S. mutans by 20.11 ± 0.27 % and 32.10 ± 4.81 % when treated with 250 μg/mL. The best docking energy was observed with viridiflorol (−29.7 kJ/mol). This study highlights that essential oil can potentially be a natural antifungal, antibacterial, and antibiofilm agent that could be applied in the pharmaceutical and food industries.

Published: March 2024

This study aims to explore the relationship between dust accumulation on a glass and various environmental factors including temperature, humidity, atmospheric pressure, and wind speed. The data was analyzed using Python, a popular language for data science and artificial intelligence, and regression algorithms from the scikit-learn library. The data was divided into training (80 %) and test (20 %) sets and different models were used, such as linear regression, decision tree, K-neighbor regression, random forest regression, and decision tree regression. The accuracy of the models was determined using R
2 scores, where a score of 1.0 indicates a perfect fit and negative values suggest that the model is worse than predicting the mean value. The accuracy of the selected models was calculated as a percentage by multiplying the obtained R
2 scores by 100. Graphs were used to visualise the data and determine the appropriate analysis model. The study found that the amount of dust is directly proportional to temperature and humidity. The accuracy levels of the linear models were suboptimal, leading to the use of nonlinear models like random forest regressor, decision tree regressor, and gradient boosting regressor, which showed improved performance.

Published: March 2024

Objective: This study was aimed at investigating the effects of the neutrophil-to-lymphocyte ratio (NLR) on the long-term prognosis of patients with acute coronary syndrome (ACS) and obstructive sleep apnea (OSA).

Methods: This prospective study enrolled patients with ACS and OSA at Anzhen Hospital between June 2015 and January 2020. OSA was defined by an apnea-hypopnea index ≥15 events·h−1. Baseline NLR was classified as high or low, according to the median. The primary endpoint was major adverse cardiovascular events (MACE), comprising cardiovascular death, recurrent myocardial infarction, stroke, and ischemia-driven revascularization.

Results: A total of 1011 patients with ACS and OSA were enrolled, 506 of whom were in the high NLR (≥2.54) group. No significant differences in sleep monitoring indicators were observed. During a median follow-up of 2.8 (1.4, 3.6) years, a non-linear correlation between NLR and the incident risk of MACE was observed. After adjustment for clinically relevant confounders, a high NLR was independently associated with elevated MACE risk (adjusted HR = 1.45, 95% CI: 1.02–2.06, P = 0.040).

Conclusions: In patients with ACS and OSA, a high NLR was associated with poorer clinical outcomes during long-term follow-up.

Authors: Hızal Kamile Tırak , Koçer Nihan
Published: March 2024

The anatomical characteristics are highlighted for Entandrophragma cylindricum, Entandrophragma utile, and Entandrophragma angolense. Wood samples, which were previously obtained from commercial timber industries in the Marmara region of Türkiye and used as course materials, were used. Qualitative and quantitative anatomical characteristics were determined. Qualitatively, characters such as distinct growth rings, diffuse-porous wood, deposits in vessel elements, simple perforation plates, alternate intervessel pits, heterogeneous ray type, and septate fibres, were common to all species. The quantitative evaluation showed that there were differences between species. Entandrophragma species differ in some wood characteristics such as the tangential diameter of the vessel, ray height, ray width, and fibre lumen diameter. E. utile had higher values of the mean tangential vessel diameter (180 μm) and fiber lumen diameter (18.4 μm) than the other two species. It is possible to say that the anatomical features of E. cylindricum differ from that of other species and that it will be easier to diagnose among other species. E. cylindricum had the lowest values of the mean tangential vessel diameter (147 μm) and ray height (361 μm). Distinctive characters for E. utile and E. angolense are tangential vessel diameter, vessel length, ray height, ray width, and all fibre dimensions.

Authors: Yan Rong , Han Yongguang , Zhang Huiyuan , Wei Cun
Published: March 2024

Energy conservation and emission reduction are important policies vigorously promoted in China. With the continuous popularization of the concept of green transportation, electric vehicles have become a green transportation tool with good development prospects, greatly reducing the pressure on the environment and resources caused by rapid economic growth. The development status of electric vehicles has a significant impact on urban energy security, environmental protection, and sustainable development in China. With the widespread application of new energy vehicles, charging piles have become an important auxiliary infrastructure necessary for the development of electric vehicles. They have significant social and economic benefits, so it is imperative to build electric vehicle charging piles. There are many factors to consider in the scientific layout of electric vehicle charging stations, and the location selection problem of electric vehicle charging stations is a multiple-attribute group decision-making (MAGDM) problem. Recently, the Combined Compromise Solution (CoCoSo) technique and CRITIC technique have been utilized to deal with MAGDM issues. Spherical fuzzy sets (SFSs) can uncover the uncertainty and fuzziness in MAGDM more effectively and deeply. In this paper, on basis of CoCoSo technique, a novel spherical fuzzy number CoCoSo (SFN-CoCoSo) technique based on spherical fuzzy number cosine similarity measure (SFNCSM) and spherical fuzzy number Euclidean distance (SFNED) is conducted for dealing with MAGDM. Moreover, when the attribute weights are completely unknown, the CRITIC technique is extended to SFSs to acquire the attribute weights based on the SFNCSM and SFNED. Finally, the SFN-CoCoSo technique is utilized for location selection problem of electric vehicle charging stations to prove practicability of the developed technique and compare the SFN-CoCoSo technique with existing techniques to further demonstrate its superiority.

Numerical modelling of flow field at shaft spillways with the marguerite-shaped inlets
Authors: Kazemipour Sina , Kabiri-Samani Abdorreza , Asghari Keyvan
Published: March 2024

By decreasing the entrained air flow discharge and improving the hydraulic characteristics of vertical shaft spillways, Marguerite-shaped inlets (MSIs) can mitigate the effects of swirling flow surrounding their inlet. The hydraulic and hydrodynamic characteristics of flow around MSIs under orifice flow regime were numerically investigated, applying different geometrical parameters. This inlet configuration can decrease the strength of swirling flow and increase the flow discharge through the shaft. The finite-volume method and the re-normalisation group k–ε turbulence model were employed to solve the governing equations of motion in a cylindrical coordinate system and a two-phase air–water flow on the water free-surface. Increasing the height and length of the blades of the MSIs was found to increase the area of the barriers against swirling flow, weaken the swirling flow strength, engender a more uniform flow and lower the water free-surface level. Extremely long or high blades, however, resulted in an intense collision of the flow with the spillway and increased the water free-surface level and the swirling flow strength at the MSI.

Abstract: This proposed community service program is an initiation in promoting environmental education which is carried out in Kertawangi Village, Cisarua District, West Bandung Regency. This 1800 Ha village is effectively dominated by plantation land so most of the livelihoods of the residents in this village are farmers. However, plantation wastes are only left to rot or are burned along with other wastes. Organic waste from plantations can be converted into important agricultural raw materials such as compost. Therefore, this service will offer Bokashi simple organic waste (composter) processing technology that can be made by the community. Bokashi can be used as an environmentally friendly feature in residential homes and indirectly as a medium for environmental education related to waste management on a micro-scale. This program will be packaged in the form of workshops and composting demonstrations. Through these workshops and demonstrations, it is hoped that the community will be able to uphold ecological values and be able to maintain the beauty and sustainability of the environment in their area.Abstrak: Program pengabdian kepada masyarakat yang diusulkan ini merupakan inisiasi dalam penggalakan pendidikan lingkungan hidup yang dilakukan di Desa Kertawangi, Kecamatan Cisarua, Kabupaten Bandung Barat. Desa seluas 1800 Ha ini secara efektif didominasi oleh lahan perkebunan, sehingga sebagian besar mata pencarian penduduk di desa ini adalah petani. Namun, limbah hasil perkebunan hanya dibiarkan membusuk atau ikut dibakar dengan sampah-sampah yang lain. Padahal, limbah organik hasil perkebunan dapat diubah menjadi bahan baku pertanian yang penting seperti pupuk kompos. Oleh karena itu, pengabdian ini akan menawarkan teknologi pengolahan limbah (komposter) organik sederhana Bokashi yang dapat dibuat oleh masyarakat. Bokashi dapat dijadikan fitur ramah lingkungan di rumah-rumah tinggal dan secara tidak langsung menjadi media pendidikan lingkungan hidup terkait pengelolaan limbah dalam skala mikro. Program ini akan dikemas dalam bentuk lokakarya dan demonstrasi pembuatan komposter. Melalui lokakarya dan demonstrasi ini, diharapkan masyarakat mampu menjunjung nilai-nilai ekologis dan mampu mempertahankan keasrian dan keberlangsungan lingkungan hidup di wilayahnya.
Institutional Proxy Representatives of Future Generations: A Comparative Analysis of Types and Design Features
Authors: Rose Michael
Published: March 2024

Future generations will be strongly affected by political decisions made today (e.g., by the long-term consequences of climate change). According to the democratic all-affected principle, the interests of everyone affected by political decisions should be considered in the political decision-making process. Future generations cannot influence democratic decision-making, since they do not yet exist. Election-based democratic incentive systems are said to make it difficult to consider the needs of future generations today. Surprisingly, however, since the early 1990s, an increasing number of democracies have established what could be called institutional proxy representatives of future generations (proxies), i.e., public bodies with institutionalized access to government and/or parliament that introduce the construed interests of future generations into the political decision-making process. Proxies help to consider future generations’ interests alongside the interests of current constituencies. After concept building, this comparative study searches all liberal democracies and identifies 25 proxies, with heterogeneous institutional designs. By employing membership criteria, three types are distinguished: (a) expertise-driven independent guardians (type I), (b) political or administrative advisory and coordination bodies (type II), and (c) sustainability stakeholder councils or committees (type III). They vary considerably in their formal capacity to influence political decision-making (i.e., on what legal basis they were provided with what instruments to address which phases of the policy process and which branches of government). Overall, they should not be overburdened with expectations. While they are usually equipped with the tools to voice the (construed) interests of future generations, they often lack the capacity to act as watchdogs with teeth when ignored.

A Comprehensive Review on Mining Subsidence and its Geo-environmental Impact
Authors: Behera Akash , Rawat Kishan Singhi
Published: March 2024

Over the course of several decades, subsidence has exerted a notable impact on the mining sector. The preponderance of subsidence occurrences is evident within coal mines. Remote sensing and Geographic Information Systems (GIS) have emerged as principal instruments for the evaluation and characterization of subsidence phenomena. The manifestation of mininginduced subsidence engenders concerns encompassing roof collapse, infrastructural damage, and the formidable challenge of preserving human lives. The repercussions of mining-related subsidence extend to indigenous flora and subterranean water reservoirs. This phenomenon critically impedes the sustainable advancement of mining zones, precipitates the depletion of natural reservoirs, and engenders a host of ecological and environmental predicaments that cast an adverse influence on socio-economic dynamics. Within mining contexts, subsidence manifests as both vertical and horizontal ground displacement, presenting as fissures, depressions, troughs, and sinkholes. The present article furnishes a comparative discourse on diverse methodologies harnessed for the assessment of mining-induced subsidence. The scholarly community has employed a repertoire of eight predominant techniques, as delineated in the conclusive remarks of this study. Over the bygone two decades, considerable strides have been taken, enabling the deployment of sophisticated paradigms, such as remote sensing and GIS, Light Detection and Ranging (LiDAR), and Differential Interferometric Synthetic Aperture Radar (DiNSAR), for the identification and quantification of land subsidence phenomena.
Performance and Emission Characteristics of CRDI Engine Fuelled with Cotton Seed Oil Blended Biodiesel
Authors: Mohanty Dillip Kumar , H. S. Anantha Padmanabha
Published: March 2024

The biofuel produced from cottonseed oil can provide a potential solution to the rapid rate of depletion and hazardous emissions of the fossil fuels for the fast-growing world. The present work investigates the suitability of cotton seed oil as a blending agent for production of biodiesel. The biodiesel blend has been tested as an alternate fuel in a common rail direct injection diesel engine from performance and emission point of view. The performance and emission parameters of biodiesel containing 10, 20 and 30 % of cotton seed oil have been compared with those of pure diesel. The experimental results indicated that the biodiesel containing 20% of cottonseed oil exhibited the most optimal performance and emission characteristics. The brake thermal efficiency of the engine decreased by 2.3% while the brake specific fuel consumption increased by 0.047kg/kWh for optimally concentrated biodiesel. Corresponding to same combustion parameters, the hydrocarbon and carbon monoxide emissions reduced by 16.5 and 58 % respectively while the nitrogen oxide emissions increased by approximately 4.8%.

This study extensively focuses on analyzing the fretting wear characteristics of Aluminum-based hybrid Metal Matrix Composites (MMCs) under dry conditions, essential in understanding materials' tribological properties in mining environments. Aluminum-based MMCs offer improved wear resistance and durability, potentially enhancing mining equipment performance. The investigation targeted Aluminum 7075 alloy-based MMCs, comprising 7% fine greenish Silicon Carbide and 3% chopped E-glass fibers (2-3mm length, 10-14 micrometer diameters). Using traditional stir casting and Friction Stir Welding (FSW) techniques, composite plates meeting ASTM standards were fabricated. FSW parameters like rotation speed and tool feed rate were varied.Analyzing fretting wear on the welded zone, employing different loads through Linear Reciprocating Tribometer (LRT), provided insights into the tribological performance of these Aluminum-based hybrid MMCs. The lightweight and exceptional thermal properties of Aluminum have significantly expanded its use across various industries, enabling partial replacement of ferrous materials, especially in MMCs where Aluminum alloys offer distinct advantages over other materials.This research aids in determining the suitability of these MMCs for demanding mining conditions, where materials endure extreme stress. Understanding their tribological behavior is crucial for potential applications in mining equipment, contributing to longevity and improved performance.
A Narrative Inquiry into Professional Quality of Life among Therapeutic Recreation Practitioners working in Long-Term Care Homes
Authors: Johnstone Jenna , Whyte Colleen
Published: March 2024

Professional Quality of Life (ProQoL) incorporates positive (e.g., compassion satisfaction) and negative (e.g., compassion fatigue and burnout) aspects of working in healthcare (Stamm, 2010). Although studies have examined ProQoL of frontline staff in long-term care (LTC) homes, the perspective of therapeutic recreation (TR) professionals is largely missing. To address this gap, this paper explores ProQoL with four TR practitioners who work in LTC homes in Ontario, Canada. Participants were invited to explore past and present experiences that contribute to ProQoL in individual interviews and write two personal narratives that embody compassion satisfaction and compassion fatigue. Narrative thematic analysis revealed 3 threads of PQoL among practitioners: fueling the soul through connection and purpose, draining the TR spirit through workplace conflict and role ambiguity, and developing professional valour. Findings suggest that although practitioners derive great fulfilment from their career, workplace culture and conflict are chronic challenges that erode the PQoL of practitioners. Recommendations for future research and practice are offered.
Peer Group Clinical Supervision: A Viable Approach for Improved Practice in Recreational Therapy
Authors: Anderson Lynn S.
Published: March 2024

Clinical supervision is the systematic interaction between professionals to promote reflection on action in practice to improve competence in the helping relationship (Anderson & Heyne, 2021). Clinical supervision between practitioners is accepted as a norm in other health and human services professions and has been shown to provide benefits for improved clinical competence. However, in therapeutic recreation, clinical supervision does not occur on a routine basis for most recreational therapists (Anderson et al., 2022). The primary reasons for the lack of clinical supervision in the field are lack of support and availability of clinical supervision at their agencies and being the sole recreational therapists on site. Group-based peer supervision is one approach that may address barriers and provide support and structure for clinical supervision. This paper provides a conceptual overview of peer supervision and presents a data-driven case study that documented the process and outcomes of a peer clinical supervision group.
Domain-Specific Service-Learning Student Reflections in Therapeutic Recreation Curriculum
Authors: Messina Emily , Davenport Brian
Published: March 2024

The use of service learning has grown within all academic areas, its use within Therapeutic Recreation curriculum is no exception. Much of the educational value of service-learning experiences comes from the reflection that occurs after the service experience. Balancing reflection assignments with a need for professional preparation can be a struggle for Therapeutic Recreation educators. Acknowledging this issue, the current article introduces a pilot study using a discipline specific service-learning reflection format. This format focuses on the students’ ability to identify both client and personal examples of the five functional domains and describe it in their reflection. Student reflections then underwent a Thematic Analysis resulting in themes of personal influence, external influence, student insight, facilitation skills, and anticipations. A brief discussion of the accuracy of students’ categorization of the domains is presented as well as limitations, future directions for research, and implications.

Authors: McDonagh Krista , Bennett Jessie , Geden Sarah
Published: March 2024

The growing prevalence of behavioral health disorders in veterans has triggered a wide-spread effort to identify and provide complementary interventions. This study investigated physical activity as a complementary treatment option for veterans with posttraumatic stress disorder (PTSD) for recreational therapy (RT) programs. A correlational survey research design was used to examine relationships between participation in three types of physical activity (traditional indoor fitness, outdoor adventure activity, and mind-body practices) and four psychosocial measures for veterans with PTSD (depression, anxiety, health-related quality of life [HRQoL], and substance use). A total of 102 participants completed the online survey. Results indicated that the frequency and duration of traditional indoor fitness activities and outdoor adventure activities were significantly associated with higher HRQoL, lower reoccurrence of substance use risk, substance use, and depression. Implications for the use of physical activity in recreational therapy for veterans with behavioral health disorders and future research studies were presented.

Background: The prevalence of stunting in Semarang City is still relatively high. Low public knowledge about stunting prevention can increase the incidence of stunting. Stunting can be prevented before pregnancy. Prospective brides are strategic targets in stunting prevention so that they can prepare for a healthy pregnancy. Increasing the knowledge of the prospective brides can be done by providing education using media that follows the characteristics of the prospective brides, namely using Android-based flipbook media. Aims: The study aims to analyze the effect of education using Android-based flipbook media on increasing knowledge, beliefs, attitudes, and intentions of prospective brides in stunting prevention in Semarang City. Method: This study used a quasi-experimental research design with a nonequivalent control group design. The sample of the research was prospective brides totaling 94 people, consisting of treatment and control groups of 47 people. Data collection used pre-test and post-test questionnaires to measure prospective brides’ knowledge, beliefs, attitudes, and intentions in stunting prevention. Results: The results showed that there were significant differences in the average knowledge score (p = 0.001), beliefs (p = 0.016), attitude (p = 0.001), and intention (p = 0.001) of prospective brides in stunting prevention. Conclusion: So it can be concluded that education about stunting prevention using Android-based flipbook media influences increasing knowledge, beliefs, attitudes, and intentions of prospective brides in stunting prevention. The greatest influence is shown on the knowledge variable, which is equal to 29,7%.
