Spatial and Temporal Divergence of Water Resource Carrying Capacity in Hubei Province, China, from the Perspective of Three Major Urban Agglomerations
Authors: Liu Zhonglan , Bao Yuanyuan
Published: June 2024

Water resource carrying capacity is indispensable for sustainable development, acting as a crucial determinant for harmonizing ecological preservation with socio-economic development. This study centers on Hubei Province, which is an important water conservation area in the Yangtze River Basin and is one of the core water source areas for the South-to-North Water Diversion Project, and evaluates the water resource carrying capacity of the three major urban agglomerations in Hubei Province from 2005 to 2020 based on the four dimensions of water resources, economics, society, and ecology, using the entropy weighting method and the TOPSIS model to construct an evaluation index system. We then employ the kernel density estimation method, ArcGIS visualization, and the Dagum Gini coefficient method to perform a comprehensive analysis of spatial and temporal differences, dynamic evolution, and contribution sources. The results show that (1) the water resource carrying capacity of Hubei Province as a whole increased from a severe overload to overload level during the study period. The water resource carrying capacity of the three major urban agglomerations shows a regional distribution pattern where the Yi-Jing-Jing-En agglomeration’s capacity surpasses that of the Wuhan urban agglomeration, which is bigger than Xiang-Shi-Sui-Shen urban agglomeration. A lower ecological water use rate primarily constrains the enhancement of the carrying capacity of water resources in Hubei Province. (2) The kernel density estimation reveals an increase in the overall water resource carrying capacity across Hubei Province’s three major urban agglomerations during the study period, alongside a pronounced trend towards polarization. (3) While the overall Gini coefficient, indicating an imbalance in water resource carrying capacity in Hubei Province, remains high, it demonstrates a declining trend, suggesting a growing disparity in water resource carrying capacity across the province’s three major urban agglomerations. Hubei Province’s water resource carrying capacity faces challenges of an overall imbalance and localized vulnerability. Strategies should aim to enhance synergy, address these deficiencies directly, and devise targeted measures tailored to the distinct features of various urban clusters.
Unlocking the Potential of Sustainable Smart Cities: Barriers and Strategies
Authors: Mutambik Ibrahim
Published: June 2024

The development of sustainable smart cities (SSCs) is pivotal for contemporary urban expansion, as highlighted by numerous international frameworks and scholarly studies. This study focused on Saudi Arabia to identify and assess the key challenges impeding the evolution of intelligent and sustainable urban environments. By categorizing and hierarchically analyzing these impediments, the research isolates the most significant barriers to SSC advancement. A total of 18 obstacles were identified, organized into four categories, and reviewed using existing scholarly literature. Semi-structured interviews were conducted with stakeholders engaged in executing SSC initiatives, enriching the research from a practical perspective. Additionally, a survey ranked these barriers, revealing that social and economic factors pose the most significant challenges, followed by governance and legal, technology, and environment. The findings of this study offer critical insights for policymakers and governments to mitigate the barriers to SSC development efforts.
Fishing for Principles: The Fairness of Fishing Quota Allocations
Authors: Gray Tim
Published: June 2024

Allocating fish quota is a hotly disputed issue across the world, and many different criteria have been employed to achieve it. However, little attention has been devoted to examining the fairness of those criteria. This study aims to fill this gap by focusing on the eight most prominent criteria that have been used or proposed—prior use; market forces; historical entitlement; geographical proximity; sovereign right; economic dependence; environmental stewardship; and equal shares—and examining their respective ethical credentials as principles of distributive justice. The assumption lying behind this aim is that if agreement can be reached on which criteria are the fairest, future conflicts over quota allocations might be averted. The method used to conduct this research was normative analysis, and the materials analysed were obtained from databases such as the Web of Science. However, the study found that the ethically strongest criteria are environmental stewardship and economic dependence, but the most prevalent criteria are historical entitlement and geographical proximity (zonal attachment). So, the principles of distributive justice that are most likely to be applied are not the fairest principles but the principles with the greatest political support. For some commentators, this signifies that justice and ethics have been sacrificed to power and politics. However, there is some evidence that the tide is turning and the arguments in favour of fairness, perhaps in hybrid forms, are beginning to gain momentum.
Recycling of Different Incineration Ashes in the Construction Sector: Perspectives from Slovenia
Authors: Zalar Serjun Vesna
Published: June 2024

The EU prioritizes transitioning to a circular economy, aiming to boost sustainable resource management through policies promoting recycling and reuse, benefiting both the environment and the economy. Many successful case studies demonstrate using various incineration waste by-products (ashes) as substitutes for natural materials, yielding environmental advantages and showcasing sustainable resource management practices. While extensive literature covers ash characterization and applications, the direct links between the properties of the main components, the amorphous phase, and research findings remain elusive. Analysis predominantly centers on microstructural phase development, influencing mechanical, physical, and chemical properties and guiding research interpretations. Existing standards for ash use primarily address coal-derived fly ash, with SIST EN 13282-2 allowing alternative sources like circulating fluidized bed and paper sludge incineration residues. Yet, beyond this standard, no regulations mandate using different ash types. Nonetheless, the applicability of ashes for the geotechnical composite materials has already been confirmed in the field since numerous geotechnical projects have been carried out in Slovenia. Such composites have been recognized as beneficial practices, and the majority of them also possess legal permission for usage according to the Slovenian Technical Approvals. Given the varying value and complexity of ashes, detailed characterization before use is crucial. Assessing the recycling potential of different ashes requires a precise definition of basic properties such as microstructure, minerals, and chemical composition. Emphasis should be placed on characterizing the hydraulic properties and gaining detailed insights into the amorphous phase, ensuring informed decision-making regarding their recycling processes.

Authors: Mabrouk Mahmoud , Han Haoying , Mahran Mahran Gamal N. , Abdrabo Karim I. , Yousry Ahmed
Published: June 2024

Despite the increasing number of flood studies, the interrelationships between urban form indices (UFIs) and flood resilience (FR) have received little attention and hold miscellaneous perspectives. Consequentially, this study identifies how UFIs at various spatial scales affect FR by synthesizing article findings and proposing insights for future research. Scientometric analysis has been used to analyze the gathered peer-reviewed articles from nine research engines without time restrictions. One hundred and eighteen relevant articles were included and thoroughly investigated using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. Our findings indicate that divergent and dialectical perspectives about the efficacy of UFIs are due to multiple disciplines, methodologies, and different case study contexts. The included studies were classified according to urban scale as macro (citywide), meso (districts), micro (block), and multi-scalar analysis by 80.5%, 6.8%, 10.2%, and 2.4%, respectively. Furthermore, the included studies were categorized based on analysis type into realistic case studies, literature reviews, modeling, and hybrid analysis, with 74.6%, 7.6%, 14.4%, and 3.4%, respectively. At the macroscale, city density and spatial distribution degree have the most significant effect on FR. At the same time, mixed uses, connectivity, coverage ratio, block arrangements, and street characteristics are on the meso and micro scales. Further studies on the trade-offs and commonality between UFIs, FR, and overall urban resilience are required to shape climate-adaptive, sustainable communities.
A Comprehensive Overview of Recycled Glass as Mineral Admixture for Circular UHPC Solutions
Authors: Redondo-Pérez N. Marcela , Redondo-Mosquera Jesús D. , Abellán-García Joaquín
Published: June 2024

This review article analyzes the influence of recycled glass (as sand and powder) beyond the durability, rheology and compressive strength of plain UHPC, even exploring flexural and direct tensile performance in fiber-reinforced UHPC. Interactions with other mineral admixtures like limestone powder, rice husk ash, fly ash, FC3R, metakaolin and slags, among others, are analyzed. Synergy with limestone powder improves rheology, reducing superplasticizer usage. Research highlights waste glass–UHPC mixtures with reduced silica fume and cement content by over 50% and nearly 30%, respectively, with compressive strengths exceeding 150 MPa, cutting costs and carbon footprints. Furthermore, with the proper fiber dosage, waste glass–UHPC reported values for strain and energy absorption capacity, albeit lower than those of traditional UHPC formulations with high cement, silica fume and quartz powder content, surpassing requirements for demanding applications such as seismic reinforcement of structures. Moreover, durability remains comparable to that of traditional UHPC. In addition, the reported life cycle analysis found that the utilization of glass powder in UHPC allows a greater reduction of embedded CO2 than other mineral additions in UHPC without jeopardizing its properties. In general, the review study presented herein underscores recycled glass’s potential in UHPC, offering economic and performance advantages in sustainable construction.
Sustainable Enablers of Knowledge Management Strategies in a Higher Education Institution
Authors: Santos Eleonora , Carvalho Milena , Martins Susana
Published: June 2024

By facilitating the capture, organization, and dissemination of knowledge within and beyond the institution, knowledge management (KM) in higher education institutions (HEIs) fuels innovation, enhances research impact, and strengthens collaboration, ultimately leading to the creation of new knowledge and its valuable exchange. However, there is still much to explore in terms of the enablers of knowledge creation, sharing, and transfer. Therefore, this paper aims to identify the enablers of effective KM in the Polytechnique University of Leiria, which serves as a benchmark for other higher education institutions due to its leadership role in RUN-EU, a consortium of European universities. To achieve this, a narrative analysis based on information from SCOPUS and the institute’s website, focusing on innovation, research, and development strategies, is proposed. The findings suggest that for KM initiatives to be successful, they need to be strategically designed, culturally supported, technologically enabled, and integrated into existing workflows.
Nonexpansiveness and Fractal Maps in Hilbert Spaces
Authors: Navascués María A.
Published: June 2024

Picard iteration is on the basis of a great number of numerical methods and applications of mathematics. However, it has been known since the 1950s that this method of fixed-point approximation may not converge in the case of nonexpansive mappings. In this paper, an extension of the concept of nonexpansiveness is presented in the first place. Unlike the classical case, the new maps may be discontinuous, adding an element of generality to the model. Some properties of the set of fixed points of the new maps are studied. Afterwards, two iterative methods of fixed-point approximation are analyzed, in the frameworks of b-metric and Hilbert spaces. In the latter case, it is proved that the symmetrically averaged iterative procedures perform well in the sense of convergence with the least number of operations at each step. As an application, the second part of the article is devoted to the study of fractal mappings on Hilbert spaces defined by means of nonexpansive operators. The paper considers fractal mappings coming from φ-contractions as well. In particular, the new operators are useful for the definition of an extension of the concept of α-fractal function, enlarging its scope to more abstract spaces and procedures. The fractal maps studied here have quasi-symmetry, in the sense that their graphs are composed of transformed copies of itself.

Dynamics of Symmetrical Discontinuous Hopfield Neural Networks with Poisson Stable Rates, Synaptic Connections and Unpredictable Inputs
Authors: Akhmet Marat , Nugayeva Zakhira , Seilova Roza
Published: June 2024

The purpose of this paper is to study the dynamics of Hopfield neural networks with impulsive effects, focusing on Poisson stable rates, synaptic connections, and unpredictable external inputs. Through the symmetry of impulsive and differential compartments of the model, we follow and extend the principal dynamical ideas of the founder. Specifically, the research delves into the phenomena of unpredictability and Poisson stability, which have been examined in previous studies relating to models of continuous and discontinuous neural networks with constant components. We extend the analysis to discontinuous models characterized by variable impulsive actions and structural ingredients. The method of included intervals based on the B-topology is employed to investigate the networks. It is a novel approach that addresses the unique challenges posed by the sophisticated recurrence.
Combinatorial Identities Concerning Binomial Quotients
Authors: Chen Yulei , Guo Dongwei
Published: June 2024

Making use of a telescoping approach, three types of sums of binomial quotients are examined. The summation terms of the two types of alternating sums have symmetry (i.e., their numerators and denominators are completely symmetric). We obtained a series of their explicit sums. Furthermore, by means of binomial relations, three recurrence relations of the sums are derived. In addition, series of double summation formulae involving binomial quotients are established.
Constructing a Machine Learning Model for Rapid Urban Flooding Forecast in Sloping Cities along the Yangtze River: A Case Study in Jiujiang
Authors: Gao Zhong , Lu Xiaoping , Chen Ruihong , Guo Minrui , Wang Xiaoxuan
Published: June 2024

Cities with sloping terrain are more susceptible to flooding during heavy rains. Traditional hydraulic models struggle to meet computational demands when addressing such emergencies. This study presented an integration of the one-dimensional Storm Water Management Model (SWMM) and the two-dimensional LISFLOOD-FP model, where the head difference at coupled manholes between the two models functioned as the connection. Based on its calculation results, this study extracted the characteristic parameters of the rainfall data, simplified the SVR calculation method and developed a high-efficiency solution for determining the maximum ponding depth. The cost time of this model was stable at approximately 1.0 min, 95% faster compared to the one from the mechanism model for 5 h simulation under the same working conditions. By conducting this case study in Jiujiang, China, the feasibility of this algorithm was well demonstrated.
A Structural Optimization of Urban Drainage Systems: An Optimization Approach for Mitigating Urban Floods
Authors: Zhang Yukun , Wang Ersong , Gong Yongwei
Published: June 2024

Urbanization and climate change increasingly challenge urban water management. In this context, the design of stormwater drainage systems, which traditionally relies on historical rainfall records, is being questioned. Although significant efforts have been dedicated to optimizing drainage networks, the upgrading of existing systems remains understudied. This research devised a set of viable stormwater drainage networks, referencing the road network of the Sino-Singapore Tianjin Eco-City (data from Google Maps). On this basis, utilizing design rainfall data (sourced from the local meteorological center), an extensive array of scenario analyses was conducted. The investigation assessed the performance of implementing two redundancy-based interventions—introducing loops and enlarging pipe diameters—as well as the patterns of flood risk response, and by integrating a multi-objective optimization algorithm, this study proposes a framework for the optimization of grey infrastructure upgrades based on component replacement. The findings suggest that a precise deployment strategy for grey infrastructure is essential. The former improves the effective flow distribution of the drainage system, while the latter enhances its flow capacity, making each intervention suitable for drainage systems with a different degree of centralization. Further research shows that an integrated hybrid scheme brings significant flood risk improvement with strong applicability for most urban drainage systems. The upgrade model proposed in this study could be a valuable initiative, offering theoretical insights for the construction and development of resilient cities.

Authors: Xu Peiwen , Jia Ziyi , Ning Huifeng , Wang Jinglei
Published: June 2024

The development and utilization of unconventional water resources has become a strategy to alleviate the agricultural water crisis in many countries and regions. To understand the research progress, hot spots, and future trends in the field of unconventional water agricultural irrigation (UWAI), this paper systematically analyzes 6738 publications based on the core database of Web of Science 1990–2023 using the scientific bibliometric analysis software CiteSpace, VOSviewer, and Scimago Graphica. The results showed that the research on UWAI is always rapidly developing. Soil science, crop science, and bioengineering are the main disciplines involved. Most research on WUAI has occurred in China and the United States. Countries with higher levels of development tend to have more influence. Collaboration among authors is fragmented, and collaboration between authors and states needs to be strengthened. Through keyword analysis, the research hotspots are summarized as follows: (1) The effects of traditional and emerging pollutants brought by unconventional water irrigation on soil physicochemical properties, crop growth, and groundwater quality; (2) the health threats caused by pollutants entering the food chain and groundwater; (3) unconventional water utilization technologies, including rainwater harvesting agriculture, precision agriculture, and urban agriculture. Future research hotspots will focus on the mechanisms of pollutant solute transport and transformation in the water–soil–crop system under non-conventional water irrigation conditions and crop physiological responses. We suggest that the research on traditional and emerging pollutants in unconventional water should be strengthened in the future, and the risk control system of unconventional water irrigation should be improved. International cooperation should be strengthened, especially with poor countries in arid regions, to promote the formation of unified international standards and guidelines for non-conventional water irrigation in agriculture.

Authors: Komarovska O.
Published: June 2024

The article reveals the role of art in actualizing the knowledge of national history by the younger generation, aimed at re-evaluating the meanings that were distorted over the centuries by the Russian and later Soviet empires.
The author’s focus is on historical events in Ukrainian history of the 20th and 21st centuries, which have dramatic and tragic meanings.
Ukrainian-centrism is defined as the basis for forming the worldview orientations of young people through art and for re-evaluating the values of all subjects of the educational process. Ukrainianness of artistic thinking as the foundation of national-patriotic education is positioned as a point of reference and at the same time a reference point for Ukrainian-centrism as a technology of musical education.
A selective review of musical works dedicated to the events of the Holodomor, the Chernobyl tragedy, Ukraine’s struggle for independence on the Maidan in 2014, during the anti-terrorist operation, and the military realities of the full-scale Russian invasion of Ukraine has been carried out. Among the authors of the works to which the article appeals are L. Dychko, S. Luniov, V. Polova, V. Sylvestrov, Ye. Stankovych, K. Tsepkolenko, Yu. Shevchenko, O. Shchetynskyi, O. Yakovchuk, S. Yarunskyi et al.
The landmark of psychological and pedagogical cultivation of an optimistic attitude towards the future as a vital need for Ukrainians is singled out. It is a key aspect of communication with pupils and student youth in the educational process based on music that actualizes historical events. The complexity of such communication regarding the embodiment of tragic images is emphasized. The necessity of forming a positive image of the future Ukraine through music that embodies the dramatic pages of Ukrainian history is emphasized. It is important for establishing the national identity of the youth and forming the motivation to protect one’s own cultural heritage.

Approches croisées de l’occupation et de l’exploitation des campagnes roussillonnaises durant le haut Moyen Âge (Ve-VIIIe siècles)
Authors: Ros Jérôme , Kotarba Jérôme , Forest Vianney , Ruas Marie-Pierre
Published: June 2024

En los últimos veinte años el desarrollo de la arqueología preventiva, las prospecciones sistemáticas y un mejor conocimiento de los indicadores cronológicos han permitido estudiar varias ocupaciones rurales de la Alta Edad Media en el Rosellón. Las operaciones realizadas, a veces en superficies extensas, han dado lugar a la aparición de una arqueología del territorio iluminada por la multiplicación de los estudios bioarqueológicos y paleoambientales (carpología, antropología, arqueozoología, geomorfología, etc.). Entre los yacimientos estudiados, seis de ellos permiten documentar los modos de implantación y organización del hábitat, así como ciertos tipos de uso de la tierra y de los recursos naturales. Así pues, la campaña del Rosellón parece estar formada por una red bastante densa de hábitats rurales polinucleares distribuidos en grandes zonas. Su organización permite optimizar la gestión de una multitud de terruños, incluso mediante la realización de grandes obras (recintos, estructuras de drenaje e incluso de riego, zonas de ensilado). El cruce de datos procedentes del estudio de diferentes tipos de vestigios arqueológicos (edificios, mobiliario, plantas y animales explotados) arroja luz sobre la historia rural del Rosellón en un momento en que el campo se reorganiza y la gama de productos alimenticios y las técnicas de cultivo cambian.
Les bâtiments sur excavation du Languedoc oriental (Ve-XIIe siècles)
Authors: Maufras Odile , Rochette Marie , Tarrou Liliane , Bergeret Agnès , Durand Christophe
Published: June 2024

L’habitat médiéval est très peu conservé en plaine du Languedoc oriental et encore mal connu. Les découvertes récentes d’une centaine de maisons à la faveur de leurs sols excavés ont suscité une analyse globale des formes de l’habitat rural du haut Moyen Âge et a permis de dépasser l’interprétation réductrice de «fond de cabane » qui prévalait jusque-là. Les excavations de sol retrouvées sous les maisons d’une demi-douzaine de sites correspondent à plusieurs types d’aménagement. Dans une vingtaine de cas il s’agit de caves occupant tout ou partie du sous-sol d’une habitation. Toujours rupestres, celles-ci varient de 4 à près de 30 m2 et se caractérisent par une faible profondeur. L’aménagement le plus fréquent est le bâtiment sur une excavation qui couvre la totalité de sa superficie et sert, soit directement de sol légèrement enterré, soit de vide-sanitaire sous plancher. Dans le premier cas, il s’agit indifféremment de maisons ou de bâtiments annexes, dans le second uniquement d’habitations. Enfin, certains sols excavés résultent de l’usure d’un simple sol de terre : ceux-ci sont moins réguliers et permettent, associés à d’autres arguments, d’identifier les étables et les bergeries. L’étude en cours des formes de l’habitat rural du premier Moyen Âge met en lumière l’évolution locale depuis l’Antiquité – plus qu’une influence exogène consécutive aux mouvements de migration – des manières d’habiter et de construire, avec un usage plus fréquent des caves, un moindre emploi de la pierre de construction au profit de la terre.

Para muchas latitudes en todo el mundo, se prevén cambios significativos en las variables climáticas, que incluyen principalmente fluctuaciones en los patrones de precipitación, aumentos de temperatura y concentraciones de CO2; tales eventos, comúnmente conocidos como cambio climático, afectan el metabolismo de las especies forestales, que debido a su importancia en la tierra han recibido especial atención por parte de la comunidad científica, especialmente en lo referente a la descripción de los mecanismos fisiológicos y bioquímicos involucrados en la respuesta de las plantas y la adaptación al estrés abiótico. Varios estudios se han desarrollado sobre este aspecto, algunos de ellos han utilizado técnicas de isótopos estables, lo que ha permitido una mejor comprensión de procesos como la eficiencia en el uso de agua y el intercambio de gases en las plantas, fenómenos relacionados con el balance de carbono y agua de los ecosistemas. La presente revisión tiene como objetivo recopilar algunos de los principales avances en el uso de isótopos estables en la ciencia forestal. Si bien los avances en este tema han sido significativos en aspectos tales como la descripción del origen de la absorción de agua por parte de las plantas, su ruta fotosintética, los cambios en la tasa de transpiración de las especies forestales, los factores climáticos que afectan el crecimiento diferencial de sus tejidos y el origen del nitrógeno durante la nutrición mineral, en el futuro tales estudios permitirán un cálculo y modelado de la fotosíntesis, una mejor comprensión de las variaciones en la transpiración y la eficiencia de la nutrición con nitrógeno a través del tiempo.

La roya amarilla del trigo causada por Puccinia striiformis f. sp. tritici se ha convertido en una enfermedad de importancia a nivel mundial en los últimos años. La resistencia genética en variedades es la estrategia más efectiva para el control de esta enfermedad. En la actualidad existen genotipos de trigo que han mostrado resistencia en diferentes años y ambientes de producción. El objetivo del presente estudio fue determinar el tipo de resistencia y estimar el número de genes que condicionan la resistencia a roya amarilla en los genotipos Glenlea, Romero 73 y Bonza 63. Se utilizó como progenitor susceptible a Avocet-YrA, se generaron tres poblaciones, las cuales se avanzaron hasta obtener familias F5. Las poblaciones se evaluaron en un ensayo con un diseño experimental de bloques completos al azar, bajo epidemias artificiales del hongo causante de la roya amarilla, en la estación experimental del INIFAP-CEVAMEX en Chapingo, México, durante el ciclo primavera-verano (P-V) 2015. La formación de rocío al 100 % y temperaturas entre 10 y 20 ºC fueron favorables para el desarrollo de la enfermedad, lo que permitió determinar que la resistencia de Bonza 63, Glenlea y Romero 73 se debe al efecto de genes menores de tipo cuantitativo. El comportamiento de las familias y el análisis de X2 indicó la presencia de tres genes que confieren resistencia de planta adulta (RPA) a roya amarilla en los genotipos Bonza 63 y Romero 73. Se determinó que la variedad Glenlea posee de cuatro a cinco genes de RPA. Bonza 63, Glenlea y Romero 73 poseen altos niveles de resistencia en planta adulta a las diversas razas presentes en las principales regiones trigueras de México y son adecuados para usarse como progenitores en los programas de mejoramiento para lograr una resistencia durable a roya amarilla.

El estado de Durango sobresale en la generación de variedades de frijol (Phaseolus vulgaris L.) con alto impacto desde el punto de vista productivo y comercial en México. El presente estudio tuvo como objetivo evaluar 14 líneas mejoradas de frijol común con base en rendimiento, calidad de grano y atributos morfo-agronómicos. Los tipos de líneas fueron: pinto (7), negro opaco (4), alubia (2) y flor de mayo (1), las cuales se compararon con testigos comerciales. La siembra se realizó en Durango, México el 10 de julio de 2015, 07 de julio de 2016 y 21 de junio de 2017. Se utilizó un diseño completamente aleatorio (franjas apareadas), con parcela experimental de seis surcos de 25 m de largo y parcela útil de dos surcos de 5 m de longitud, 0.81 m de separación (8.1 m2) y cinco repeticiones. Se registraron los días a floración (DF), días a madurez fisiológica (DMF), rendimiento, peso de 100 semillas y se realizó análisis químico proximal del grano. Se aplicó análisis de varianza y la comparación de medias se realizó con la prueba de Tukey (P ≤ 0.05). Se observaron valores entre de 44 y 51 días después de siembra (dds) para DF y de entre 96 y 110 dds para DMF. Las líneas de frijol pinto mostraron precocidad a la floración (39 dds) y madurez (100 dds). Se obtuvieron diferencias significativas (de P ≤ 0.0001 a P ≤ 0.04) entre líneas para rendimiento de grano, con un promedio mayor en 2016 (2673 kg ha-1) y variaciones para el tamaño del grano de 45.0 a 51.1 g por 100 semillas. No se detectaron diferencias estadísticamente significativas entre líneas para el contenido de cenizas (3.5 a 5.0 %), proteína cruda (20.5 a 25.1 %), grasa cruda (1.2 a 2.2 %), fibra cruda (1.9 a 4.4 %) y extracto libre de nitrógeno (65.8 a 71.2 %). Se identificaron líneas mejoradas sobresalientes de frijol con adaptación en riego, alto rendimiento y calidad nutricia y comercial del grano.

La información sobre el volumen y la biomasa de los árboles es importante para determinar la retención de carbono en bosques. El objetivo del presente estudio fue estimar el volumen, biomasa y contenido de carbono de especies arbóreas en un bosque de Durango, México. Se establecieron nueve sitios de muestreo de 50 × 50 m y se realizó un censo de todas las especies arbóreas. Para cada uno de los árboles muestreados se registró la especie, se midió el diámetro normal y la altura total. Para cada una de las especies se determinó su volumen y biomasa total a través de ecuaciones alométricas generadas pordiferentes autores. Para determinar el contenido de carbono se multiplicó el valor de la biomasa por el factor 0.5, ya que según resultados de varios autores este valor representa la concentración promedio de carbono para especies de coníferas y hojosas. En total se registraron 11 especies, pertenecientes a cuatro géneros y cuatro familias. El bosque presenta una densidad de 575 árboles ha-1, un volumen total de 207.36 m3 ha-1 y una concentración de biomasa total de 130.28 Mg ha-1. Con relación al carbono, se estimó un total de 65.14 Mg ha-1. Las especies con mayor volumen, biomasa y carbono acumulado fueron Pinus durangensis, P. cooperi y Quercus sideroxyla. El área basal es la mejor variable indicadora del contenido de carbono en el área de estudio.

Published: June 2024

This research explores the neurobiology of emotional regulation using multimodal imaging techniques and its clinical implications for psychiatric disorders. Through a systematic literature review, we examine the key findings from neuroimaging studies investigating the neural circuits underlying emotional regulation across diverse populations and contexts. We discuss the consistent and divergent findings, methodological challenges, and therapeutic implications derived from these studies. Additionally, we identify gaps in the current literature and suggest future research directions, including the need for longitudinal studies, exploration of individual differences in emotional regulation, and integration of multimodal imaging with other methodologies. Furthermore, we discuss the methodological challenges and opportunities for advancing the field of multimodal imaging in studying emotional regulation, emphasizing the importance of continued interdisciplinary research. Overall, this research underscores the significance of understanding the neurobiology of emotional regulation and its clinical relevance for improving mental health outcomes and developing personalized interventions for individuals with psychiatric disorders.

Maintaining soil fertility and structure in Libya requires attention to water quality and irrigation practices due to limited arable land. This study aims to assess groundwater quality in the Brack-Ashkada, Libya agricultural project based on physicochemical parameters such as electrical conductivity, total dissolved solids, total hardness, and irrigation water quality index (IWQI), as well as some cations and anions, and irrigation indices such as sodium adsorption ratio (SAR), residual sodium carbonate, percentage sodium, permeability index, Kelly's index, potential salinity, total hardness (TH), and magnesium hazards percentage. The results indicated that IWQI is positively correlated with SAR and TH and negatively correlated with the remaining indices. Based on the irrigation indices, the groundwater of the three wells was suitable for irrigation and can be classified as moderately water-restricted. The Piper diagram suggests that the mixed-type Ca-Mg-Cl-SO4 was dominant in the wells. The study concludes that groundwater is partially safe for agricultural use, but specific safety measures must be taken. These findings will assist farmers in enhancing soil management, crop cultivation, and land sustainability.

Bu araştırma, "cittaslow” statüsüne sahip Bolu ilinin Göynük ilçesindeki yöresel mutfağın ayırt edici özelliklerini ortaya çıkartarak bu yemeklerin sürdürülebilirliğini etkileyen faktörleri incelemek ve cittaslow unvanının ilçedeki yöresel yemek kültürünün sürdürülebilirliği üzerindeki etkisini araştırmayı amaçlamaktadır. Odaklanan araştırmada, veriler nitel araştırma yöntemlerinden derinlemesine mülakat ve kaynak taramasıyla elde edildi. Çalışma örneklemini, Göynük ilçesindeki konaklama ve yeme-içme işletmeleri ile bölgede yaşayan yerel halk oluşturmaktadır. Benzer nitelik ve nicelikteki kişilere ulaşabilmek için araştırma örneklemi kartopu örneklemi ile olarak belirlendi. Alanında uzman akademisyenlerinde görüşü alınarak oluşturulmuş olan 4 soru ilçede yöresel yemek hakkında bilgisi olan katılımcılara yöneltilmiştir. Araştırma bulgularına göre, Göynük'te coğrafi tescil potansiyeli yüksek ve sürdürülebilirliği önemli olan yöresel ürünler ortaya çıkartıldı. Bu yöresel ürünlerin ortaya çıkışında, ilçenin cittaslow ağına katılımının etkisi olduğu gözlemlenmiştir. Turistik faaliyetlerde bulunanlar tarafından tercih edilmelerine rağmen, yöresel gastronomik ürünlerin işletmelerde yeterince temsil edilmediği, sunum düzeyinin düşük olduğu ve bilimsel olarak kayıt altına alınmaları konusunda sadece belediye tarafından bir çalışmanın yürütüldüğü belirlenmiştir.
