Salt and ammonia exposure response and bioaugmentation mechanism in anaerobic digestion of food waste.

Rational proton engineering offers a powerful strategy for enhancing the hydrogen evolution reaction (HER) performance of single-atom catalysts (SACs). Notably, achieving concerted proton management across multiple reaction steps presents a highly efficient approach, yet it remains more challenging to implement than single-step regulation. Here, we propose a domino-type proton provision-conversion-spillover programming for Pt SACs in acidic HER, enabled by ultrathin porous nitrogen-doped carbon (main 1-2 atomic layers, sub-1nm) encapsulated TiN nanowires with tips as dual-support tip-platform (Pt-NC1@TiN NWs). Experimental and theoretical results demonstrate that this platform triggers tip-distance-spillover domino effects to drive a proton cascade throughout HER. Specifically, NC1@TiN nanotips induce tip-enhanced effect that promotes interfacial proton accessibility. Concurrently, the short-distance Pt/TiN vertical coupling optimizes electronic modulation of unsaturated Pt-N2 sites to enhance their intrinsic activity. Exposed TiN sites function as hydrogen spillover centers to facilitate H2 desorption. Consequently, Pt-NC1@TiN NWs achieve a superior Pt mass activity of 153.5 A/mgPt@-100mV, surpassing Pt/C by two orders of magnitude. Notably, it reaches 2 A/cm2 at low cell voltage of 1.75V and sustains stable operation at 1 A/cm2 for 1200h in proton exchange membrane water electrolyzer (PEMWE). This work indicates the potential of harnessing multi-step domino processes for advanced catalyst design.

Achieving efficient, single-phase ultra-broadband visible emission under mild excitation remains a key challenge in lead-free perovskite optoelectronics. In this work, we demonstrate that B-site heavier alkali metals can trigger a structural "domino effect" in the layered perovskite derivative (C4H14N2S2)2Cs2InCl9, leading to spontaneous symmetry breaking and ultra-broadband photoluminescence (PL) upon Sb3 + doping. This unique "domino effect" is initiated by the close packing of the faced-tricapped trigonal prism CsCl9 8- within the 2D inorganic layer and propagates via the charge-balancing interplay of intercalated chloride anions. The bonding of Cl- with three amine groups of the biprotanated cystamine, in turn, asymmetrically influences the inorganic layer, resulting in the formation of two distinct indium chloride octahedra. Consequently, Sb3 + doping enables ultra-broadband visible emission through a distortion-modulated cooperative dual-site mechanism. Our findings establish B-site-driven phase transition as a powerful and heretofore overlooked strategy for developing high-performance luminescent materials.

The Domino Effect of Tragedy.

The use of language that tends to be harsh, sarcastic, and emotional shows how today's young generation articulates their dissatisfaction with public figures, mostly driven by feelings of disappointment with the past of these figures. This case is also related to the domino effect phenomenon, where previous negative events or information about public figures can trigger strong reactions or protests from certain groups. The flower arrangement at UNAIR illustrates how critical literacy, in the context of Indonesian culture that is filled with values of politeness, can be developed as an important skill among young people. This paper examines the answer of the chairman of BEM FISIP UNAIR, Tuffahati Ulayyah from the Harian Surya video podcast script. This study highlights the importance of critical literacy in education, showing that a lack of ability to evaluate and express opinions ethically and responsibly contributes to weaknesses in student critique.

Abstract In 2022–2023, three local‐magnitude (M L ) 4.8–5.6 earthquakes shook the Peace River oilsands area of Alberta, Canada. Previous studies statistically linked the seismicity to nearby disposal activities but lacked in‐depth investigation into triggering mechanisms, including subsurface fluid migration and earthquake interaction. Here, we identify the seismicity as a directional, cascading rupture process initiated by wastewater disposal and sustained by tectonic fault interplay. Our findings highlight the role of regional geologic framework, a combination of a capped fringing‐reef formation and a truncated fault, in channeling injected fluids. Injection above this architecture was effectively isolated, whereas fluids entering the reef formation progressively destabilized the fault, culminating in the M L 5.6 event on 30 November 2022. This mainshock triggered a southeastward rupture cascade, including two M L 4.8+ events on 16 March 2023. Earthquake swarms were primarily nucleated by the nearest reef‐targeted disposal well, with secondary contributions from wells located 20–35 km away.

After the Opium War, the number of treaty ports surged from five to dozens, with foreign goods extending inland along the Yangtze River while domestic exports expanded from Guangzhou to multiple competitive ports. The traditional "tribute-gift and merchant vessels" system collapsed, silver depreciated, and tax revenues flourished, triggering a domino effect across finance, markets, and society. Foreign trade evolved from peripheral mutual markets into a transformative force shaping national destiny. Each shift in commodity composition, settlement methods, or shipping routes triggered reconfigurations in domestic industries, regional hierarchies, and social stratification. The late Qing economy thus integrated into the global capital system — not passively, but through profound adjustments on its existing foundation, forging a unique industrialization and commercialization trajectory characteristic of a semi-colonial society.

Purpose of the study: This study aims to uncover the characteristics of Indonesian students' mathematical literacy, the challenges they face in solving mathematical problems, and to propose effective solutions, including technology-enhanced interventions, for improvement. Methodology: This study uses a qualitative phenomenological approach to explore students’ experiences in mathematical literacy. Data were collected through AKM-based algebra tasks, interviews, and observations involving three purposively selected middle school students. Method triangulation ensured validity, while digital tools, including audio recording and NVivo software, supported systematic qualitative data coding and analysis. Main Findings: The findings indicate that students’ incorrect answers often arise from difficulties in identifying key problem elements. This misidentification triggers cascading errors across subsequent problem-solving steps, creating a domino effect. Analysis revealed distinct patterns in communication, mathematization, representation, problem-solving strategies, symbolic operations, and reasoning. These patterned error trajectories align well with digital logging, automated analysis, and real-time feedback, enabling direct application in designing digital assessment platforms, intelligent tutoring systems, and learning analytics dashboards to diagnose learning breakdowns. Novelty/Originality of this study: This study uniquely bridges qualitative phenomenological analysis with concrete technological design, systematically translating error patterns into detection algorithms, scaffolding rules, and dashboard specifications. Unlike prior research that either describes difficulties or proposes technology, we explicitly operationalize how intelligent systems can detect and respond to cascading error patterns in real time. The result is a contextually grounded framework for AKM-aligned technology implementation tailored to Indonesian educational realities, including infrastructure constraints and teacher capacity.

Purpose This paper aims to examine the role of market competition, artificial intelligence (AI) adoption maturity and consumer pressures significantly in frugal innovation in the manufacturing sector. It also explores the potential impact of market competition and consumer pressures on AI adoption maturity and the impact of these interactions on social impact. Design/methodology/approach The empirical data for this study were collected through a structured survey from 331 managers, heads of departments and AI specialists in the manufacturing sector of Jordan and analyzed using the Smart PLS program. Findings The results revealed that market competition and consumer pressures significantly impact AI adoption maturity and frugal innovation. The findings also confirmed that AI adoption maturity significantly improves frugal innovation efforts. Furthermore, it was found that AI adoption maturity significantly moderates the role of frugal innovation in creating social impact. Research limitations/implications This study is constrained by a sample of manufacturers in Jordan and one questionnaire that could limit generalization of results and predispose the study to bias. Furthermore, the quantitative cross-sectional type is not able to show the dynamics of the temporal nature or qualitative settings of the relationships between the variables. Therefore, this paper recommends further research, which is geographically and cross-sector extended, the utilization of longitudinal designs and the utilization of qualitative research to investigate causal associations and the processes of organization and culture in more depth. Practical implications The model can be applied in practice by businesses to understand how the adoption and maturity of AI can affect rational innovation and responsiveness to market and consumer pressures. It helps companies to develop strategies that could contribute to the increase of the positive social value of innovations and add competitiveness. The management can use this model to focus on the investments it has made in technology and expand the capacity needed to become a successful innovator. Originality/value The contribution of the present research lies in its focus on the institutional and social features of frugal innovation, which has a notably strong role to play to maximize it, but the maturity of AI plays a key role in this. This study can not only research the direct relationships between variables but also examine the relationship between the institutional forces, digital changes and innovation of firms. It provides practical suggestions on the necessity to invest in AI to become a sustainable, frugal innovator. Additionally, it is a good academic contribution because it integrates not only methodological novelty with AI but also social elements, in this way expanding the horizons of future studies in the area of AI adoption, frugal innovation and social impacts of innovation.

Yemen's strategic position in the region has led to the escalation of its internal conflict into a proxy war between Saudi Arabia and Iran. This study aims to analyze the impact of Yemen's proxy war on Middle East geopolitics from 2015 to 2023, employing a qualitative descriptive content analysis with a regional geopolitical approach, informed by literature study techniques in data collection. The results showed that the proxy war in Yemen has impacted Middle Eastern geopolitics, particularly in the security and economic sectors. Iran's support for the Houthis militia has prompted responses from other regional countries based on their respective interests. The intensity of Houthi attacks on Yemen's border areas has also created border insecurity and increased tensions between countries in the region. Meanwhile, in the economic and trade sectors, the proxy war in Yemen has resulted in increased operational tariffs on regional trade, forcing countries to adjust their economic policies. This study reinforces the notion that a country's geographic position influences the geopolitics of the surrounding region and has the potential to create a domino effect on regional political instability, as seen in the conflict in Yemen.

ABSTRACT The​‍​‌‍​‍‌​‍​‌‍​‍‌ exponentially rising story of GLP-1 drugs such as Ozempic, Wegovy, and Mounjaro has been not only one of the best medical stories but also a great economic event of the past ten years. Simply these drugs that were initially aimed at type 2 diabetics have turned out to be the most reasonable way of weight loss which happens to be a side effect of appetite regulation. Consequently, the demand forGLP-1 drugs has skyrocketed so that companies from different sectors like healthcare, food and beverage, fitness, fashion retail, insurance, and pharmaceuticals are changing customer behavior, supply chains, and strategic operations radically just by the domino effect of GLP-1 drugs.This research is an investigation into the business and economic effects of the widespread use of GLP-1. Through literature review, market data, and industry analyses, the paper explores the alteration in consumer habits, the transformation of traditional markets, and the companies' reaction through innovation due to the widespread use of the drugs. The results reveal that GLP-1 is not merely a medical breakthrough but also a major economic shift that has the potential to change the face of numerous industries for quite a few years to ​‍​‌‍​‍‌​‍​‌‍​‍‌follow.
