Self-Compacting Recycled Concrete Using Biomass Bottom Ash
(MDPI, 2021)In recent years, the use of self-compacting concrete has been a great advantage and garnered undoubted interest in construction. Due to the environmental impact caused by the consumption of natural aggregates in the ... -
Social Media, Thin-Ideal, Body Dissatisfaction and Disordered Eating Attitudes: An Exploratory Analysis
(MDPI, 2019)Disordered eating attitudes are rapidly increasing, especially among young women in their twenties. These disordered behaviours result from the interaction of several factors, including beauty ideals. A significant factor ... -
Soil Salinity Patterns in an Olive Grove Irrigated with Reclaimed Table Olive Processing Wastewater
(MDPI, 2022)The agricultural use of saline table olive processing wastewater enables the implementation of closed water cycles in this socioeconomically important industry for rural southern Spain and relieves environmental, economic, ... -

Ternary Blends for Self-Compacting Mortars Production Composed by Electric Arc Furnace Dust and Other Industrial by-Products
(MDPI, 2022)This study is framed within the circular economy model through the valorisation of industrial by-products. This research shows the results of producing self-compacting mortars (SCMs) with electric arc furnace dust (EAFD) ... -
Testing Accuracy of Long-Range Ultrasonic Sensors for Olive Tree Canopy Measurements
(MDPI, 2015)Ultrasonic sensors are often used to adjust spray volume by allowing the calculation of the crown volume of tree crops. The special conditions of the olive tree require the use of long-range sensors, which are less ... -
Testing the Suitability of a Terrestrial 2D LiDAR Scanner for Canopy Characterization of Greenhouse Tomato Crops
(MDPI, 2016)Canopy characterization is essential for pesticide dosage adjustment according to vegetation volume and density. It is especially important for fresh exportable vegetables like greenhouse tomatoes. These plants are thin ... -
The contribution of fruit and leaves to the dynamic response of secondary branches of orange trees
(Elsevier, 2020)The current commercial technologies for mass harvesting fruit are based on the application of forced vibration to the tree, which is transmitted to the fruits causing their detachment. The dynamic behaviour of the plant ... -
The Effects of Port Water Injection on Spark Ignition Engine Performance and Emissions Fueled by Pure Gasoline, E5 and E10
(MDPI, 2020)It has been proven that vehicle emissions such as oxides of nitrogen (NOx) are negatively affecting the health of human beings as well as the environment. In addition, it was recently highlighted that air pollution may ... -
The Experimental Study of the Utilization of Recycling Aggregate from the Demolition of Elements of a Reinforced Concrete Hall
(MDPI, 2020)The article shows a case study as to whether the thermal and mechanical recycling of concrete is suitable for concrete debris from the demolition of structural elements of a 30-year-old industrial hall. The experiment ... -
The Influence of Heat and Mechanical Treatment of Concrete Rubble on the Properties of Recycled Aggregate Concrete
(MDPI, 2019)Concrete is a building material commonly used for ages. Therefore, in the result of repairs or demolition of building structures, large amounts of concrete rubble are created, which requires appropriate management. The aim ... -
The mechanical performance of recycled slate waste fiber composites based on unsaturated polyester resins
(MDPI, 2023)In the last few decades, there has been increasing social awareness for environmental conservation, which is driving the development of composite materials based on natural fibers. These new materials have interesting ... -
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
