Advanced Industrial Stormwater Management in Dense Urban Environments: Lessons from New York City

Santunu Barua

Read Abstract

The high rate of urbanization, the growing rate of industrialization, and climate-related events of extreme precipitation have greatly increased the complexity of the stormwater management demands in major cities around the world. The city of New York (NYC) has a high impervious surface coverage, antiquated mixed sewerage systems, and dense industrial land cover, indicating that it is a high-risk location regarding the assessment of advanced industrial stormwater management control measures. The study is a literature-based systematic investigation of the success of modern stormwater management strategies in use in industrial areas in NYC, specifically focusing on hybrid green-through gray infrastructure systems. The study conducted a synthesis of regulatory reports, hydrological monitoring datasets, and empirical studies by peer reviewers in order to determine quantitative results regarding runoff volume reduction, reduction of pollutant loads, and combined sewer overflow (CSO) control with the help of a secondary-data-driven research design. It has been shown that the following advanced industrial stormwater interventions have been associated with significant decreases in total suspended solids, nutrient loads and peak runoff volumes: bioswales, green roofs, subsurface detention systems and smart monitoring technologies, and also improved regulatory compliance in federal and municipal systems. In addition, it has been indicated that integrated infrastructure models would be more efficient in terms of cost and the benefits of resilience over the long term than the traditional end-of-pipe solutions. The novelty of the study consists in the synthesis of the industrial-scale stormwater management in the dense urban morphology with a specific focus on the and explicit connection of technological performance, regulatory implementation, and environmental performance. This study can be generalized to policymakers, urban planners and industrial stakeholders wishing to develop robust data-driven stormwater infrastructure in comparably limited urban areas by generalizing empirical experiences in NYC.

Extreme-Intensity Laser–Matter Interactions and the Emergence of Strong-Field Quantum Electrodynamics in the Petawatt Era

Luca Romano

Read Abstract

The rapid evolution of ultra-high-power laser technology over the past two decades has fundamentally transformed the experimental and theoretical landscape of high-field physics. The realization of petawatt-class and multi-petawatt laser systems has enabled laboratory access to electromagnetic field strengths approaching, and in some regimes exceeding, those naturally occurring in extreme astrophysical environments. This technological leap has catalyzed the emergence of strong-field quantum electrodynamics as an experimentally accessible domain, where radiation reaction, nonlinear Compton scattering, Breit–Wheeler pair production, and quantum electrodynamic cascades play dominant roles in laser–matter interactions (Danson et al., 2015; Di Piazza et al., 2012). Recent demonstrations of laser intensities surpassing twenty-three orders of magnitude in watts per square centimeter have further narrowed the gap between theoretical predictions formulated in the mid-twentieth century and their direct empirical validation (Yoon et al., 2021). Within this context, the present article develops a comprehensive and critical examination of extreme-intensity laser–matter interactions grounded strictly in the provided literature corpus. The analysis integrates historical developments in laser science, foundational quantum electrodynamics in strong fields, and contemporary experimental and numerical studies of radiation reaction and electron–positron plasma formation. Rather than offering a cursory overview, the article elaborates each concept through extensive theoretical background, scholarly debate, and critical interpretation, emphasizing unresolved tensions between classical, semiclassical, and fully quantum descriptions. Particular attention is devoted to the role of laser-driven particle accelerators, plasma mirrors, and laser–beam collider geometries in enabling experimentally feasible access to nonperturbative regimes of quantum electrodynamics (Bell and Kirk, 2008; Vincenti, 2019; Magnusson et al., 2019). The results section interprets reported findings as emergent patterns within the literature, while the discussion situates these findings within broader debates on the limits of current models, experimental constraints, and the future trajectory toward exawatt-class facilities. By synthesizing advances in laser technology with developments in strong-field theory, this article aims to provide a publication-ready, deeply analytical contribution to the understanding of how extreme light–matter interactions redefine both plasma physics and fundamental quantum theory.

Kadyrova Zulayho Raimovna, Niyazova Shokhista Mansuraliyevna, Kodirova Umida Aslonovna, Alikhonova Zukhra Saitdkhodjayevna, Kazakova Munira Narzikulovna

Read Abstract

The development of refractory materials based on local magnesia–silicate resources of Uzbekistan is a promising approach for resource conservation and import substitution. In this study, a comparative assessment of serpentinites from the Sultan-Uvays (Republic of Karakalpakstan) and Arvaten (Jizzakh region) deposits was carried out as a raw-material base for producing magnesia refractories of the MgO-SiO₂ system. The chemical composition and impurity components were analyzed, and the structural and morphological features of the samples were investigated using FTIR spectroscopy and SEM-EDS. According to the SEM-EDS results, the spectra are dominated by O-Si-Mg signals, while Fe peaks show relatively low intensity and only trace impurities are detected. The FTIR spectra exhibit characteristic bands of the serpentine structure (ν(OH) ~3565-3675 cm⁻¹, Si-O ~954-1069 cm⁻¹, and Si-O-Mg/Mg-O modes ~734-400 cm⁻¹). The obtained results confirm the potential of serpentinites from both deposits as local magnesia-silicate raw materials and substantiate their use for producing MgO-SiO₂ refractory materials, including forsterite-type compositions.

Salikhanova Dilnoza, Muxtasar Ismoilova, Munisa Mamajonova, Axror Abdurakhimov, Dilafruz Sagdullaeva, Raxnamo Nazirova

Read Abstract

The article explores the production and quality evaluation of halva made from sunflower seed kernels and sunflower seed meal. Various formulations were tested to determine the optimal composition based on organoleptic, nutritional, and physicochemical indicators. The results showed that halva prepared from sunflower seed kernels exhibited the best quality characteristics, including balanced sweetness, oiliness, and texture. In contrast, samples made with sunflower meal or a 50/50 mixture had a darker color and lower fat content, reducing their market appeal. The analysis of vitamin and mineral content revealed that sunflower kernel halva contained higher levels of calcium and zinc, enhancing its biological value. Overall, the optimal formulation contained 45 g of sunflower kernels, 25 g of sugar, 15 g of water, one egg, and 4 g of sesame seeds, providing a product with high nutritional and sensory quality.

The Adsorptive Purification Of Low-Quality Glycerin By Biocarbon Adsorbents

Salikhanova Dilnoza Saidakbarovna, Savrieva Dilafruz Doutovna, Ismailova Mukhtasar Abdumutalib kizi, Sagdullaeva Dilafruz Saidakbarovna, Abdurakhimov Akhror Anvarovich, Karabaeva Muslima Iftikhorovna

Read Abstract

This study investigates the purification of low-quality glycerin using biocarbon adsorbents derived from cherry pits. The carbon adsorbent produced (ACCP) demonstrated superior efficacy in reducing glycerin color, decreasing it from 10 mg I₂/100 cm³ to 5 mg I₂/100 cm³, outperforming the imported coconut carbon adsorbent (ACC), which only achieved a reduction to 6 mg I₂/100 cm³. It has also been established that a carbon adsorbent with a particle size of 2-3 mm is considered optimal, as smaller particles hinder filtration, thereby increasing ash content due to the migration of fine carbon particles into the filtrate. A reduction in the acid number by 5-6 times allows for an improvement in the quality of glycerin and extends its shelf life. It has been determined that the carbon adsorbent derived from cherry pits selectively reduces the amount of free fatty acids. Initial glycerin parameters corresponded to grade T-88 specifications; however, after treatment with the synthesized adsorbents, the parameters improved to meet the D-98 standard requirements. These findings suggest that cherry pit-based adsorbents are a promising alternative for purifying glycerin in various industrial applications.

Reconceptualizing Hyperautomation in Financial Workflows: Integrative Frameworks, Organizational Contexts, and Generative Artificial Intelligence as a Catalyst for Intelligent Process Transformation

Dr. Elias Van der Merwe

Read Abstract

The accelerating complexity of organizational operations, coupled with increasing regulatory, competitive, and technological pressures, has intensified scholarly and practical interest in hyperautomation as a comprehensive paradigm for enterprise transformation. Hyperautomation extends beyond traditional automation by integrating advanced digital technologies such as robotic process automation, process mining, artificial intelligence, and, more recently, generative artificial intelligence into cohesive, adaptive systems capable of continuous learning and optimization. Financial workflows, characterized by high transaction volumes, strict compliance requirements, and deep interdependencies across organizational units, represent a critical domain in which hyperautomation promises transformative value. This study develops a theoretically grounded and empirically informed analysis of hyperautomation in financial workflows, emphasizing the role of generative artificial intelligence and process mining as foundational enablers of intelligent orchestration and decision support. Drawing strictly on established scholarly literature, including contemporary research on artificial intelligence in decision-making, business process management, robotic process automation, organizational culture, and family enterprise governance, the article constructs an integrative conceptual framework that situates hyperautomation within broader organizational, technological, and human contexts. Particular attention is devoted to the socio-technical dynamics that shape adoption outcomes, including cultural embeddedness, trust in explainable artificial intelligence, human–machine collaboration, and ethical considerations surrounding data governance and privacy. Through an extensive descriptive and interpretive analysis, the study elucidates how generative artificial intelligence enhances hyperautomation by enabling semantic understanding, adaptive reasoning, and context-aware process optimization in financial domains. The findings suggest that hyperautomation should be understood not merely as a technological upgrade but as an evolving organizational capability that reshapes governance structures, professional roles, and strategic decision-making. The article contributes to academic discourse by bridging fragmented research streams and by articulating a comprehensive agenda for future research on intelligent automation in finance, with implications for both large enterprises and family-owned firms operating in increasingly digitalized environments.

Augmented Rainwater Infiltration & Pollutant Mitigation (ARIPM) Systems for Industrial Stormwater Management

Santunu Barua

Read Abstract

The process of industrial urbanization has significantly transformed the nature of hydrological processes supporting natural phenomena and enhanced the amounts of stormwater runoff, the amount of discharge peaks, and the mobilization of contaminants on impervious industrial surfaces. The traditional drainage models that are mainly used to facilitate quick flow have become ineffective in dealing with the hydrological imbalance and also the loading of contaminants and especially in face of the mounting pressures of the extreme rainfall events caused by climate change. The article focuses on Augmented Rainwater Infiltration and Pollutant Mitigation (ARIPM) systems as a combined stormwater management system to fit an industrial catchment. The main purpose is to assess the hydrological efficiency and the attenuation ability of ARIPM systems based on a synthesis of empirical field research, monitored systems and regulatory performance databases. The analysis is based on the quantitative evaluations of infiltration enhancing and reduction of runoff volume, attenuation of peak flows, and elimination of major industrial stormwater pollutants like total suspended solids, nutrients, hydrocarbons, and heavy metals. The results show that ARIPM systems can always increase infiltration rates and decrease the surface runoff and have significant reductions in the contaminants load using physical filtration, sorption and biogeochemical processes. The variability of the performance is noted in soil conditions, rainfall regimes, and typologies of industrial land-use, which emphasize the significance of the site-specific design and maintenance strategies. The originality of the paper is placing ARIPM systems within the paradigm of a hybrid green-grey infrastructure that is based on the hydrological restoration and the controlled industrial pollutants, which is not always a dominant theme in the study of stormwater. The findings show that ARIPM systems can provide a scalable, robust, and regulatory-compliant solution to enhance industrial stormwater management and increase the urban environment resilience.

Information Technology and Natural Language Processing in Education: A Systematic and Bibliometric Review (2020–2025)

Marwah Naeem Hassooni

Read Abstract

The development of digital health crowdfunding has become a crucial alternative source of financing, and the research on it is still incomplete. The proposed study will utilize the PRISMA protocol and bibliometric methods, performance analysis, Bradford Law, and science mapping to 121 articles being indexed in Scopus (2010-2025). Findings present four journals at the heart of the research, such as Journal of Medical Internet Research, Social Science and Medicine, Journal of Medical Ethics, BMC Public Health, and Information Processing and Management, with an overall lack of disciplinary focus. The field is organized into thematic clusters, which are trust and transparency, equity and inclusion, technology integration, and platform governance. They also change the thematic direction greatly as those investigations that were aimed at descriptive explorations in the early 2014-2021 are replaced with the middle debates of the 2022-2023 era (which are still centered on legitimacy), and the newer concerns (2024-2025) are centered around equity, regulation, and new technologies (AI, blockchain, gamification, etc.). Given the apparent lack of theoretical cohesiveness despite the burgeoning development of the discipline, this paper provides the first systematic bibliometric synthesis of digital health crowdfunding and demands integrative, theoretically grounded frameworks of connections between donor behaviour, platform governance, and systemic inequities.

Echocardiographic Characteristics Of The Heart In Pulmonary Artery Stenosis Among Patients Aged 1 To 29 Years

Khudayberdieva Khamrokhon Tillavaldievna, Sabirov Akram Akdaralievich, Khashimova Zamira Makhmudjanovna

Read Abstract

Background: Pulmonary artery stenosis (PAS) is one of the most common congenital heart defects in children and young adults. Echocardiography remains the leading non‑invasive method for assessing morphological and functional cardiac changes. However, age‑related echocardiographic parameters in PAS are insufficiently studied, which complicates diagnostic standardization.

Aim: To evaluate age‑related echocardiographic characteristics of the heart in patients with pulmonary artery stenosis aged 1–29 years.

Methods: A total of patients aged 1–29 years with PAS were examined. Echocardiography was performed using two‑dimensional, M‑mode, and Doppler techniques. Subjects were divided into five age groups: 1–4, 5–9, 10–14, 15–19, and 20–29 years. Parameters assessed included right atrial and ventricular dimensions, interventricular septal thickness, pulmonary artery diameter, and systolic/diastolic function.

Results: In early childhood (1–4 years), right atrial enlargement predominated, while right ventricular size remained within normal limits. At 5–9 years, atrial dilation persisted with initial wall thickening of the right ventricle. Adolescents (10–14 years) demonstrated ventricular enlargement and early hypertrophy. In young adults (15–29 years), progressive hypertrophy of the right ventricle and interventricular septum was observed, accompanied by pulmonary valve regurgitation. These findings confirm heterochronous and heterodynamic remodeling processes in PAS.

Conclusion: Age‑related echocardiographic changes in PAS vary from chamber dilation in childhood to hypertrophy and remodeling in adolescence and young adulthood. Recognition of these patterns is essential for accurate diagnosis, risk stratification, and individualized treatment planning.

Comparative Study of Mechanical and Ultrasonic Homogenization in the Production of Food Oil–Water Emulsions

Salikhanova Dilnoza, Muxtasar Ismoilova, Iqlima Choriyeva

Read Abstract

This study examines laboratory methods for producing food-grade oil–water emulsions based on purified reheated vegetable oils using phospholipid emulsifiers. Conventional mechanical homogenization and ultrasonic homogenization were compared in terms of emulsion quality and stability. The effects of oil concentration, emulsifier type, processing temperature, and mixing time were evaluated. Ultrasonic homogenization at 20 kHz produced finely dispersed emulsions with droplet sizes of 0.1–0.5 µm and stability of up to 30–35 days. Optimal stability was observed at oil contents of 15–20% and temperatures of 50–60 °C. The results show that emulsions from reheated oils are comparable to those from fresh oils and can be effectively used as release agents in bakery and confectionery production.

A Scalable Architecture for Intelligent Document Processing in Multi-Cloud Environments

Suprakash Dutta

Read Abstract

This paper reviews an easily expandable plan for smart document handling across multiple cloud systems, aiming to make work easier to manage, more resilient to issues, and improve the total cost of ownership. The importance of this task stems from two factors: first, Intelligent Document Processing (IDP) tools are experiencing growth; second, multi-cloud use is expanding more widely. This increases the primary fight between wanting top-notch help for every step and the dangers of being stuck with one provider, having messy operations, and uneven safety rules. The study aims to create and support a complete design that can hide both setup and software links while offering complete control and standard protection in a mixed environment. The innovation is in the coherent four-layer model, which merges a general control plane atop Kubernetes and Crossplane with portable application runtime Dapr, exposing standard APIs for statelessness, messaging, and service invocation, decomposed IDP microservices, and an overlay layer for management and security. The key findings validate that only the combination of Crossplane at the level of the control plane with GitOps and OPA policies together with Dapr at the level of the application-API can provide real portability, elastic scaling, governed security, while maintaining freedom of choice between cloud services. It proves that workflows crossing provider boundaries can be orchestrated, thus reducing vendor lock-in. The article will be helpful to cloud-platform architects, IT executives, data and MLOps engineers, IDP product teams, and researchers in distributed systems and enterprise AI.
