The Performance of Concrete Made with Secondary Products—Recycled Coarse Aggregates, Recycled Cement Mortar, and Fly Ash–Slag Mix
(MDPI, 2022)The properties of cement concrete using waste materials—namely, recycled cement mortar, fly ash–slag, and recycled concrete aggregate—are presented. A treatment process for waste materials is proposed. Two research experiments ... -
The role of pH on leaching of heavy metals and chlorides from electric arc furnace dust in cement-based mortars
(Elsevier, 2018)Electric arc furnace dust (EAFD) presents a pollution hazard due to its heavy metal leachability. Its characterization is essential for recovery or disposal in hazardous waste landfills. The present work discusses the ... -
The role of powder content of the recycled aggregates of CDW in the behaviour of rendering mortars
(Elsevier, 2019)In recent years, the number of studies on the incorporation of recycled aggregate (RA) into mortars has grown considerably. However, mixed recycled aggregate (MRA) is investigated on a much smaller scale due mainly to its ... -
The use of artificial intelligence for sign language recognition in education: from a literature overview to the ISENSE project
(IEEE, 2023)Common strategies to guarantee the inclusion of d/Deaf students in university are still absent. Recent studies have demonstrated how innovative technologies, such as artificial intelligence and virtual/augmented reality, ... -
The vibration behaviour of hedgerow olive trees in response to mechanical harvesting with straddle harvester
(Elsevier, 2019)Understanding tree behaviour under mechanical harvesting is very important for orchard management and machine design. The objective of this work is to determine the Dynamic response of trees, in a hedgerow arrangement, to ... -
Towards an Optimized Method of Olive Tree Crown Volume Measurement
(MDPI, 2015)Accurate crown characterization of large isolated olive trees is vital for adjusting spray doses in three-dimensional crop agriculture. Among the many methodologies available, laser sensors have proved to be the most ... -
Training program on sign language: social inclusion through Virtual Reality in ISENSE project
(IEEE, 2023)Structured hand gestures that incorporate visual motions and signs are used in sign language. Sign language is a valuable means of daily communication for individuals who are deaf or have speech impairments, but it is ... -
Tuberculosis and Other Airborne Microbes in Occupational Health and Safety
(MDPI, 2020)Airborne pathogens and non-malignant infectious diseases such as tuberculosis are highly contagious and can have severe effects on healthcare workers. The symptoms of these diseases take time to manifest, which can prevent ... -
Understanding why women don’t choose engineering degrees
(Springer Nature, 2019)Despite the continuous efforts of governments and universities to avoid the underrepresentation of women entering engineering degrees, the trend has not reverted, and this is a general fact all over the world. This fact ... -
Universal Kinetic Model to Simulate Two-Step Biodiesel Production from Vegetable Oil
(MDPI, 2020)To date, to simulate biodiesel production, kinetic models from different authors have been provided, each one usually applied to the use of a specific vegetable oil and experimental conditions. Models, which may include ... -
Universal multifractal description of an hourly rainfall time series from a location in southern Spain
(Universidad Nacional Autónoma de México, 2008)El formalismo multifractal de turbulencia ha sido usado para llevar a cabo el análisis de la estructura temporal, para escalas desde 1 hora hasta casi 6 meses, de la serie de datos de lluvia horaria registrada durante ... -
Upscaling the Use of Mixed Recycled Aggregates in Non-Structural Low Cement Concrete
(MDPI, 2016)This research aims to produce non-structural concrete with mixed recycled aggregates (MRA) in upscaled applications with low-cement content. Four slabs were executed with concrete made with different ratios of coarse MRA ... -
Use of Carbonated Water as Kneading in Mortars Made with Recycled Aggregates
(MDPI, 2022)The increased concern about climate change is revolutionising the building materials sector, making sustainability and environmental friendliness increasingly important. This study evaluates the feasibility of incorporating ... -
Use of Nanomaterials in the Stabilization of Expansive Soils into a Road Real-Scale Application
(MDPI, 2020)Stabilization is a traditional strategy used to improve soils with the main objective of ensuring that this base is compliant with the technical specifications required for the subsequent development of different ... -
Use of Periodic Mesoporous Organosilica–Benzene Adsorbent for CO2 Capture to Reduce the Greenhouse Effect
(MDPI, 2024)The CO2 adsorption of a phenylene-bridged ordered mesoporous organosilica (PMO–benzene) was analyzed. The maximum capture capacity was 638.2 mg·g−1 (0 °C and 34 atm). Approximately 0.43 g would be enough to reduce the ... -
