The punching of holes or recesses on computer numerical control coordinate presses occurs in sheets at high speeds (up to 1200 strokes/min) with an accuracy of ~0.05 mm. One of the most effective approaches to the wear rate reduction of stamping tools is the use of solid lubricants, such as wear-resistant coatings, where the bulk properties of the tool are combined with high microhardness and lubricating ability to eliminate waste disposal and remove oil contaminants from liquid lubricants. This work describes the efficiency of complex CrAlSiN/DLC:Si coatings deposited using a hybrid unit combining physical vapor deposition and plasma-assisted chemical vapor deposition technologies to increase the wear resistance of a punch tool made of X165CrMoV12 die steel during coordinate punching of 4.0 mm thick 41Cr4 carbon structural steel sheets. The antifriction layer of DLC:Si allows for minimizing the wear under thermal exposure of 200 °C. The wear criterion of the lateral surface was 250 μm. The tribological tests allow us to consider the CrAlSiN/DLC:Si coatings as effective in increasing the wear resistance of stamping tools (21,000 strokes for the uncoated tool and 48,000 strokes for the coated one) when solving a wide range of technological problems in sheet stamping of structural steels.

Recently, there has been a growing demand for plant-based products to treat a range of health conditions. Platostoma menthoides (L.), a member of the Lamiaceae family, is widely known for its versatile therapeutic properties. The primary aim of this study is to analyze and identify the secondary metabolites found in the extract of P. menthoides obtained using ethyl acetate and to assess its antioxidant, antimicrobial, and mosquito larvicidal properties for the first time. For the chemical profiling, a GC–MS analysis of the extract was conducted, and it showed the presence of various phytoconstituents, and the FT-IR spectrum revealed the functional groups associated with them. The quantitative phytochemical estimations revealed values of 34.87 ± 0.53 mg of GAE equivalents/g and 22.19 ± 1.11 mg of QUE equivalents/g, respectively, for total phenolic and flavonoid content. The biological studies of P. menthoides extract showed potent mosquito larvicidal activity against fourth instar larvae of Aedes aegypti at a 100 µg/mL concentration with LC50 and LC90 values of 81.328 and 161.471 µg/mL, respectively. Moreover, the DPPH and FRAP radical scavenging potentials were evaluated, and the results revealed their ability to scavenge the free radicals. The extract also showed higher antibacterial effects against gram-negative bacteria when compared to gram-positive bacteria. All these findings suggest that P. menthoides is a rich source of phytoconstituents with various medicinal applications and can be used as an antioxidant, antibacterial, and mosquito-larvicidal agent.
Pertussis Vaccination for Adults: An Updated Guide for Clinicians
Authors: See Kay Choong
Published: January 2025

Pertussis, or whooping cough, is a highly contagious respiratory infection caused by the Gram-negative bacterium Bordetella pertussis. Although traditionally associated with children, pertussis is increasingly prevalent among adults, particularly those with comorbidities or weakened immune systems, where it can lead to severe complications. Diagnosing pertussis in adults can be challenging due to its nonspecific symptoms, underreporting, and the limited sensitivity of available diagnostic tests. While treatment with macrolides is generally effective, it may not significantly alter the clinical course of the disease, and growing concerns about macrolide resistance are emerging. Vaccination remains the cornerstone of prevention, offering proven immunogenicity, efficacy, and safety. However, vaccination uptake remains low, partly due to limited patient awareness and insufficient prioritization by healthcare professionals. This review aims to provide clinicians with critical insights into pertussis epidemiology, vaccination strategies, and the latest guideline recommendations, empowering them to engage in meaningful discussions with adult patients and advocate for increased vaccination to combat this often-overlooked infection.
Integrated Water Resources Management After 2030: An Agenda for Educators
Authors: Grigg Neil S.
Published: January 2025

This paper addresses the need to improve the understanding of how integrated water resources management (IWRM) can be more effective in addressing diverse water challenges globally. The emphasis is on the use of systems methods to clarify IWRM and create support for it among the academic community for emphasis after the Sustainable Development Goals (SDGs) expire in 2030. The importance of using IWRM is apparent in frequent reports about challenges like access to water supply and sanitation, water-related disasters, water stresses, water pollution, and ecosystem losses. These affect the SDGs, especially Goal 6 for implementation of IWRM. Among competing paradigms for water resources management practice, IWRM has a more organized advocacy base than others, and sustaining it can support all of them. However, IWRM has been supported for more than 20 years and is still difficult to understand and criticized. Despite this, sustained support for it indicates that it meets an important need. Systems concepts of problem archetypes, skeletonization, and the concept of emergence were used to create a model to explain IWRM as a framework of institutional arrangements and a cooperative problem-solving process. A set of four synthesized problem archetypes was developed, and stakeholder analysis was used to identify key disciplines for its implementation and to identify the knowledge, skills, and abilities needed among them. These point the way for academics to develop clear explanations while retaining comprehensive perspectives of IWRM. Building and sustaining a viable academic community to support IWRM will face barriers because academics focus mainly on their disciplines where they are rewarded and recognized. This is also evident in the smaller membership bases of interdisciplinary water associations compared to disciplinary or sector-based water associations. IWRM as an organizing platform for cross-sector water resources management has a long-term future if academics focus on it and its support by international partners continues. By explaining IWRM better and marshalling greater support for it among the academic community, the same approach of clarifying ambiguous concepts and providing better ways to engage academia may help other SDG areas.
Sustainable Utilization of Dewatering Sludge for the Development of Reinforcement Grouting Materials in Downhole Applications
Authors: Zhu Xianxiang , Du Yanhui , Li Song
Published: January 2025

The mining and processing of coal resources generate substantial coal-based solid wastes, such as coal gangue and slag, which pose environmental challenges, occupy land, and are difficult to manage. However, utilizing these wastes for the stabilization and solidification (S/S) of municipal sludge containing chromium (Cr) and nickel (Ni) offers an effective solution for mitigating environmental and groundwater pollution while enabling sustainable waste treatment and resource utilization. This study applied an alkali-activated coal gangue–S95 granulated blast furnace slag-based binder (CGS) to the S/S treatment of municipal sludge. The effects of the liquid-to-solid ratio, alkali activator dosage, sludge content, and incineration on compressive strength and the leaching of Cr and Ni were analyzed. The results showed that compressive strength decreased with increases in the sludge content and liquid-to-solid ratio, while incinerated sludge (ESA) samples exhibited better strength than raw sludge (ES). Incineration decomposed the calcite (CaCO3) into CaO, which facilitated the oxidation of Cr(III) to Cr(VI) and increased Cr leaching in the ESA. However, the ESA samples demonstrated superior heavy metal stabilization, as CGS reduced Cr(VI) to Cr(III) and immobilized it through the formation of chromite phases. Using ESA as a binder in CGS provides a safe, efficient approach for resource recovery and heavy metal stabilization, offering a novel solution for the environmental management and utilization of coal-based solid wastes.

The making of a professional: Insights from four decades within vocational education
Authors:   , Terry Stuart
Published: January 2025

This study delves into the complex construction of professional identity among professional administrative staff within New Zealand’s vocational education sector, marking a significant contribution to the discourse on professional identity in this context. Since the beginning of the 21st century, research into the professional identity of staff within higher education has emerged, predominantly within university settings or focusing on leadership roles. However, there has been a lack of research specifically addressing the special character of vocational education in New Zealand.

Originating from my personal experiences, observations, and reflections on my work identity and the factors and environments that have influenced both my own identity and those of others, this study draws upon my time working in the New Zealand vocational education sector from 1979 to 2024. It combines my journey with the stories of eighteen participants and insights from three eminent practitioners, employing a methodological mix of autoethnography, narrative inquiry, and qualitative description. This approach sheds light on the intricate interaction between individual experiences and the broader institutional, societal, and political forces that shape professional identity.

The findings introduce new knowledge and perspectives to the conversation about professional identity construction within higher education. The study highlights the critical themes of the importance of nomenclature, the influence of professional space, self-perception, shaped through the foundational influences of family and whānau, and the crucial roles of leadership and professional networks in shaping identity. These themes reveal the complex interplay between individual and collective identity narratives, particularly within the unique context of vocational education in the New Zealand higher education sector.

At this pivotal moment for vocational education, this study provides practical implications for practice and policy. By enhancing the understanding and cultivation of professional identity among non-teaching staff, a heightened sense of professional identity not only enriches the professional lives of staff but also strengthens their commitment and engagement, thereby contributing to the delivery of applied vocational education relevant to the workplace of the 21st century.

Authors: Jagemma Milkessa , Worku Hailu
Published: January 2025

Background: This study sought to determine the spatial distribution of heavy metal concentrations in water, soil, and vegetables that were irrigated with industrial wastewater in Ethiopia’s Oromia Special Zone. We aimed to make recommendations for corrective actions that would reduce the negative environmental effects of untreated waste. Methods: Five sampling sites were meticulously chosen within the Sululta, Laga Tafo Laga Dadi, Galan, Sabata, and Burayu regions, taking into account the varying stressors across the upper stream, middle stream, and downstream segments of the rivers. These sampling sites were strategically selected to capture a comprehensive understanding of heavy metal aggregation within the area. The sampling encompassed the collection and analysis of 25 water and wastewater samples, 13 soil samples, and 8 vegetable samples. The distribution of sampling efforts was tailored to reflect the availability of irrigation sites within the respective areas, resulting in a harmonized amalgamation of 5, 3, and 1 samples for water and wastewater, soil, and vegetable matrices, respectively. Results: The lettuce in the Gelan area had the greatest quantity of lead, suggesting higher cancer risk. The sites of Gelan and Burayu had significant levels of chromium contamination in their lettuce, followed by their cabbage, according to the WHO/FAO and USEPA. As a result, those who eat vegetables that have high levels of heavy metal contamination may be at risk for developing cancer. Conclusion: The concerned institutions and stakeholders must work to mitigate the high concentration of heavy metals in water, soil, and vegetables by the installation of treatment plant.

Published: January 2025

Introduction: Photodynamic therapy (PDT) is a photochemical treatment that involves the use of light and photosensitizer. This method is applied as a therapeutic approach against several types of cancer. The main aim of this study is to compare the efficacy of PDT with that of cisplatin (a well-known chemotherapy agent) through protein-protein interaction (PPI) network analysis. Methods: Gene expression profiles of human melanoma A375 cells from the Gene Expression Omnibus (GEO) were selected for analysis via directed PPI network analysis. The significant differentially expressed genes (DEGs) were identified and assessed based on co-expression interactions. The critical DEGs were introduced by considering out-degree and in-degree values. Results: Two directed PPI networks for upregulated and downregulated DEGs were constructed. TP53 was identified as a critical upregulated gene in response to cisplatin in comparison with PDT. EGFR, PPARG, MMP9, PTGS2, FOXO1, and RUNX2 were highlighted as the crucial downregulated genes due to the effect of cisplatin on the gene expression of the treated cells. Conclusion: Cisplatin directly targets key cellular functions such as cell growth, differentiation, migration, and invasion. It seems that the combination of cisplatin and PDT is a suitable method for treating cancers because cisplatin targets the key genes responsible for cancer development, while PDT intensifies the effect of cisplatin and reduces its side effects.
From Homo Sapiens to Homo Excultus: Stages of Development and Formation
Authors: Leontyeva Oksana
Published: January 2025

The study considers the stages of culture formation through the comprehension of the term Homo excultus. We define the role and place of Homo excultus in the formation of the value space of culture. An attempt has been made, using the latest research in neuroscience and other related disciplines, to explain more fully the reasons for the emergence of Homo excultus. We propose a new vision on the formation of the value system of culture, which began to be created from the moment of uniting people into small communities. The distinctive features of each culture were laid down in these communities in the process when the image of the surrounding world began to be created in the human psychic field. Culture and its values were formed simultaneously. Cultural codes emerged on the basis of values that had already been formed

This research aims to evaluate the government policies implemented by Wajo Regency in resolving the complex challenges encountered by the Lake Tempe fishermen. It is difficult to determine the core cause of the Lake Tempe conflict because there are various local terms and interpretations from many researchers with diverse backgrounds. Therefore, this article seeks to provide a more detailed description of the conflict chronology as well as many of the terms used in Lake Tempe studies. This study gathered academic journals, scholarly literature, and related sources using a narrative review technique. The findings from all the articles are interpreted, summarized, and elaborated in a descriptive manner using implementation and evaluation concepts. Through the analysis of the collected data, the research findings reveal that the Wajo Regency administration issued particular regulations to control fisheries resource management to resolve the discrepancies between Pallawang and Pakkajalalla fishermen. The objective was to promote stability while empowering the community to manage fishing resources. However, the regulation's implementation was ineffective because of the limited availability of specialized human resources in the fisheries department, which hindered the successful execution of the policy. Furthermore, it shows that the enacted regulations contradict each other in terms of policy coherence. While the first issue concerns the fishing method, it has now evolved into a problem for the government to solve between the fisheries and agriculture sectors

This study aims to assess the effectiveness of housing financing facilitation and assistance policies for low-income people (LIP) in Bekasi District, with a case study of Villa Kencana Cikarang Housing. A qualitative descriptive approach with a case study design was utilized, applying Khan & Khandaker's rational model of policy implementation to evaluate five key variables: clarity of policy objectives, detailed and consistent planning, clear division of tasks, accurate standardization, and proper supervision. The findings reveal several issues, including policy targets that do not reflect the housing needs of each region, inaccuracies in targeting FLPP mortgage recipients, limited planning of FLPP credit/financing schemes, a shortage of human resources in implementing organizations, and various obstacles in post-distribution monitoring related to occupancy. Practical recommendations from this study include setting policy targets based on the proposed housing needs of each region, continuously developing and evaluating the current government housing credit/financing schemes to expand their implementation and utilization beyond LIP to include the poor and non-LIP groups, accelerating staff recruitment and rotation in implementing organizations, and ensuring inherent supervision by involving developers to monitor occupancy rates and applying strict sanctions to LIP who violate the provisions on the use of subsidized housing.

Moreover, the Aceh government considers ulama to be the government's communication link to the community. Therefore, this article aims to understand perceptions and identify the involvement of ulama, both directly and indirectly, in handling Covid-19 in Aceh. The method used is qualitative with a phenomenological approach. The database comes from in-depth interviews, participant observation and documentation studies. Meanwhile, technical data analysis uses an inductive approach and is analyzed interactively. The research results show thatThe role of ulama has become crucial in efforts to handle and manage the impact of Covid19 in Aceh. Ulama play an important role in raising public awareness during the Covid-19 pandemic. Through collaboration with the government, ulama participate in socializing government policies down to the grassroots level to suppress the spread of Covid-19. It is not just an appeal but is also involved in disciplining the community regarding health protocols, supporting preventive measures, providing psychological and spiritual support, as well as encouraging social solidarity, and even taking part in the Covid-19 vaccination program. Ulama have helped unite communities in facing the Covid-19 crisis in Aceh

Driving as a Creative Activity for Disabled People
Authors: Oravecz Adrienn
Published: January 2025

Driving is rarely considered a creative activity, yet it contains many elements that can inspire creative thinking and problem-solving skills. While driving, the driver constantly responds to changing environmental factors, such as traffic, weather, or road conditions. This dynamic attention encourages quick decision-making and flexible thinking, as there is often a need to adapt spontaneously to the situation. Adaptive driving technologies and vehicle modifications enable drivers with physical or sensory disabilities to personalize their driving experience in ways that suit their unique needs, opening up avenues for self-expression and problem-solving. Additionally, planning routes and choosing the optimal path require creative thinking, especially in unfamiliar locations or unusual situations. In such cases, the driver must consider navigation options, traffic rules, and even timing—all skills that are valuable in other creative processes as well. By learning to maneuver these vehicles confidently and efficiently, drivers with disabilities not only overcome mobility barriers but also redefine traditional approaches to driving, transforming it into a creative skill that mirrors their resilience and adaptability.
