Wetlands provide multiple ecosystem services that multiply the social, economic, and environmental development of the population; However, these problems undergo environmental problems that accelerate the eutrophication process. The purpose of this research was to evaluate the trophic states of Medio Mundo’s main lagoon of the Albufera Regional Conservation (ACRAMM). For this, the Carlson Trophic State Index modified by Toledo (IETM) was used and a predictive mathematical model for the total water phosphorus was formulated; where the dependent variable was represented by the parameter and the independent ones, by the reflections of Sentinel-2 images. The ACRAMM, according to the phosphorus model, was eutrophic on the first 5 dates evaluated (IETMPT> 65.56) and from oligotrophic to eutrophic with a tendency to increase from south to north on the last date (IETMPT = 38.29-56.99).

The introduction of artificial intelligence methods and techniques in the construction industry has fostered innovation and constant improvement in the automation of monitoring and control processes at construction sites, although there are areas where more studies still need to be conducted. This paper proposes a method to determine the criticality of cracks in concrete samples. The proposed method uses a previously trained YOLOv4 neural network to identify concrete cracks. Then, the region of interest, determined by the bounding box resulting from the neural network model classification, is extracted. Finally, the extracted image is converted to negative grayscale to quantify the number of white pixels above a certain threshold, automatically allowing the system to characterize the fracture’s extent and criticality. The classification module reached a veracity between 98.36% and 99.7...

The way in which individuals and groups explain poverty shapes how they relate to it. This paper inquires the beliefs of university students about the causes of poverty and analyses the relation of these beliefs with their professional training area. An assessment instrument that considers three type of attributions -individualist, socio-structural and fatalistic-, was administered to a sample of 448 advanced university students belonging to nine social sciences programs, aged between 19 and 42 years (M = 22.92; SD = 3.12). The results obtained indicate important variations in the explanations about poverty according to the professional training area. Students of economic sciences emphasized the importance of individual factors, psychology and law students tended to mixed explanations and sociology students showed a wide preference for socio-structural causes over individual and fatalist...

El continuous growth of the construction industry is directly linked to significant environmental impacts. According to the United Nations Environment Programme (UNEP) in 2020, the operation and construction of buildings contribute to 38% of all carbon dioxide (CO2) emissions related to energy. UNEP emphasize the need for a three-fold strategy to address this issue: aggressively reduce energy demand in built areas, decarbonize the energy sector, and implement material strategies that reduce carbon emissions throughout the lifecycle of products. To quantify the Carbon Footprint, an approach called Life Cycle Assessment (LCA) is used, which involves assessing the impact on climate change by considering the entire value chain of a product or service, including inputs and greenhouse gas (GHG) emissions. To evaluate the sustainability of a formwork, it is necessary to evaluate the carbon foot...
