This study aimed to develop a comprehensive typology of Sudanese sorghum-farming households within their food security status to inform targeted agricultural policy and rural development strategies. Using survey data from 392 households across 11 Sudanese states, the research captures the structural, socio-economic, and geographical diversity of farming systems and scrutinizes the relationship between socioeconomic characteristics of farmer households and related probability of constituting a specific farmer type. To assert this, Principal Component Analysis (PCA), hierarchical clustering, and Multinomial logistic regression analysis were applied. Through PCA and hierarchical clustering, three types of farmers were identified: The first type (Vulnerable Farmers), characterized by low education levels, small landholdings, high food insecurity, and reliance on subsistence farming; The second type (Well-off Remote farmers), operating larger landholdings meant for commercial purposes, yet facing challenges related to geographic isolation and limited market access; The third type (Educated Farmers with access to urban areas), consisting of households with higher education, diversified income sources, and proximity to markets, though still experiencing persistent food insecurity. Multinomial logistic regression analysis confirmed that household size, age, education, land size, market distance, and income structure are significant predictors of respective types of farmers. Thus, the study stands as a tool to enlighten intended/future policies, in providing input support and credit for vulnerable farmers, infrastructure and market access for remote commercial farmers, and land tenure security with innovative-geared incentives for farmers interacting with urban areas to foster inclusive, adaptive agricultural policies, and sustainable development across Sudan’s diverse farming communities.

A Multi-Index Performance Framework for Evaluating Binder Synergy and Fly Ash Reactivity in Eco-Sustainable Cementitious Composites
Mahmoud Abo El-Wafa
This study presents a multi-index performance system that is systematically used to assess the binder synergy and fly ash reactivity of eco-sustainable cementitious composite (ESCC) using the Strength Activity Index (SAI) as a reference in line with ASTM C618. The partial replacements of fly ash with high and low calcium fly ash (HCFA and LCFA) were added to the fly ash to sand (FA/S) ratios of 0, 10, 20, and 30% with a constant mix parameter, such as a 50% ratio of water to slag and a 20% ratio of activator to slag. Initial Flow Index (IFI) and Flow Retention Index (FRI) were used to measure fresh-state performance, and compressive-, tensile-, and flexural-based indices, i.e., SAI, Tensile Strength Index (TSI), and Flexural Strength Index (FSI), were used to measure mechanical performance. The results indicate that flowability and workability retention decrease with an increase in FA/S ratio, with LCFA-based mixtures having better flow retention than HCFA systems. The optimum mechanical performance at a replacement level of 20% FA/S produced the maximum SAI values of about 112% HCFA and 110% LCFA with a consistent increase in TSI and FSI values at 28 days. When the replacement levels were increased (30% FA/S), all strength indices decreased with the effect of dilution and decreased the packing efficiency of the binder. Comparisons of SAI with the respective TSI and FSI values through correlation analysis showed that the quantitative relationship between compressive, tensile, and flexural behavior was definite and showed that compressive strength alone is not enough to extrapolate mechanical performance. Collectively, the proposed framework provides a reasonable performance-based basis for the manner in which fly ash could be utilized in the most effective way in eco-sustainable cementitious compositions.

District heating systems are central to Europe’s decarbonisation efforts and its 2050 climate-neutrality target. However, given the deep embedding of district heating in the socio-economic system and built environment, meeting policy targets at the local level gives rise to a range of technical, infrastructural and socio-economic challenges. This is due to the high complexity and multidimensionality of the process, as well as the scarcity of local resources (e.g. land, surface waters, waste heat, etc.). In Bucharest, Romania, the largest district heating system in the European Union, the process of decarbonisation represents a particularly complex challenge. The system is characterised by high technical wear, heavy dependence on natural gas, significant heat losses and complex governance structures. This paper presents a strategic planning exercise for aligning the Bucharest system with the Energy Efficiency Directive 2023/1791. Drawing on system data, investment modelling and local resource mapping from the LIFE22-CET-SET_HEAT project, it evaluates scenarios for 2028 and 2035 that shift generation from natural gas to renewable, waste heat and high-efficiency sources. Options include large-scale heat pumps, waste-to-energy, geothermal and solar heat. Heat demand profiles and electricity price dynamics are used to evaluate economic feasibility and operational flexibility. The findings show that technical decarbonisation is possible, but financial viability hinges on phased investments, regulatory reforms and access to EU funding. The study concludes with recommendations for staged implementation, coordinated governance and socio-economic measures to safeguard affordability and reliability.

Forest ecosystems are vital to global carbon cycling as sinks or sources, while fast-growing, adaptable pines such as P. kesiya and P. oocarpa are central to national carbon sequestration efforts. This study was aimed at determining biomass accumulation variations and carbon stock dynamics between these two species at the age of 16 years in the Viphya Plantations, a prominent timber producing area in northern Malawi. Following the systematic sampling, forest inventory data was collected from 20 circular plots of 0.05 ha each. Above and below ground biomass was estimated using generic allometric models for pine species. Findings indicate that there were significant (P<0.001) differences in biomass accumulation and carbon sequestration between P. oocarpa and P. kesiya plantations. P. oocarpa accumulated more biomass (298.86±12.09 Mgha-1) than P. kesiya (160.13±23.79 Mgha-1). Furthermore, P. oocarpa plantation had a higher annual carbon sequestration (32.22±1.30 tCO2e/ha/yr) as compared to P. kesiya plantation (17.26±2.56 tCO2e/ha/yr). In addition, the uncertainty was less than 1% and fit within the IPCC’s recommended range (<15%). Therefore, the study has demonstrated that species selection should match management objectives: P. oocarpa maximizes short-to-medium term carbon sequestration and productivity, while P. kesiya supports long-term soil carbon stability. Hence, integrating both optimizes carbon benefits.

Nurse-Led Development and Pilot Evaluation of a Hypertension Self-Management App in a Rural, Underserved Academic Medical Setting
Mary Louanne Friend
Background/Objectives: Rural and underserved adults face barriers to hypertension (HTN) self-management, and in-person lifestyle education programs in academic medical settings may have limited reach This pilot study evaluated a publicly available HTN self-management app (iOS/Android) with respect to feasibility, perceived usefulness, user satisfaction, and user-entered metrics relevant to HTN and lifestyle management. Methods: We conducted an internet-based, single-arm pilot of a mobile app available in commercial app stores. Adults aged ≥19 years who downloaded the free app and reported HTN self-enrolled via in-app registration and electronic consent; no direct recruitment or compensation was provided. Outcomes included an in-app questionnaire (HTN history, perceived BP status, concern, and a key self-management behavior) and app engagement/health-entry data (registration counts; use of tracking features; distributions of user-entered metrics). Results: From June 2020–July 2025, 819 users completed the in-app questionnaire; five were excluded as spam (N=814). Responses clustered in 2021 (76.8%), and completion time was brief (median 91 s; IQR 65–131). Most respondents reported hypertension for >2 years (57.3%; 21.5% unsure). Perceived BP was “normal” (42.1%), “borderline” (24.8%), or “high” (15.2%), with 15.0% unsure. For a key self-management behavior, only 21.8% reported measuring their blood pressure “usually/always,” while 24.8% reported never measuring their blood pressure. More than half were at least somewhat concerned about their BP (56.6%). Conclusions: In a largely rural, southeastern context, this publicly available HTN app demonstrated feasible low-touch uptake and captured user-entered self-management data, though sustained tracking occurred in a subset of users. Findings support further pragmatic testing focused on engagement, equity, and integration into nurse-led care workflows.

Technological Asymmetries and Financial Performance of Industrial Joint‑Stock Companies: AI‑Driven Risk Factors and Efficiency in Capital Management
Aneta Ejsmont
This article examines how technological asymmetries—understood as differences in access to advanced digital tools, AI capabilities and IT infrastructure—shape the financial stability and market performance of enterprises of various sizes. The study integrates comparative analyses of 100 industrial joint-stock companies from multiple countries, including technologically advanced large corporations and innovative SMEs, to assess how disparities in digitization and AI implementation influence financial resilience. Using multivariate regression models and index-based financial metrics such as MC, EV, P/E, PEG, P/S, P/B, EV/R and EV/EBITDA, the research identifies relationships between technological advancement, operational efficiency and risk exposure. The findings indicate that companies with higher levels of digitization and AI adoption demonstrate stronger resistance to market disruptions, more effective risk management and more favorable capital structures than SMEs with limited technological resources. However, restricted access to detailed operational data for smaller firms may affect the precision of comparative assessments. The study concludes that investments in digital competences and international cooperation enhance financial stability and support strategic decision-making, while SMEs play an important complementary role by providing outsourcing services that facilitate AI implementation in larger corporations.
