The Organisational Structure of an Agent-Based Model for the Management of Wastewater Systems
Water managers have to deal with complex problems due to the intertwined characteristics of processes, in particular those that occur in wastewater systems. Existing modelling approaches are usually centred in the physical, ...
Kinetics of the Thermal Degradation of Poly(lactic acid) and Polyamide Bioblends
Poly(lactic acid) (PLA) and biosourced polyamide (PA) bioblends, with a variable PA weight content of 10–50%, were prepared by melt blending in order to overcome the high brittleness of PLA. During processing, the properties ...
Efect of type of emitter self‑cleaning mechanism and its structure on the performance of drip irrigation system using efuent of rainbow trout fish
The anti-clogging ability of the emitters depends on their automatic self-cleaning mechanism, the structure and geometry of the fow path, and the type of material carried by irrigation water. Suspended solids in fsh farm ...
Environmental assessment of underdrain designs for a sand media filter
Increasing energy demand is the main problem linked with the adoption of more efficient irrigation techniques, particularly microirrigation. In microirrigation systems, important pressure losses and therefore energy ...
Electrifying secondary settlers to enhance nitrogen and pathogens removals
Economic options to retrofit wastewater treatment plants (WWTPs) without tertiary treatments need to be explored. In this regard, bioelectrochemical systems (BES) can be hybridized with existing technologies, upgrading the ...
First report of verticillium wilt and mortality of ailanthus altissima caused by Verticillium dahliae and v.albo-atrum sensu lato in spain
Notification of the presence of new pathogens or diseases (of plants) in certain geographical areas (countries, regions, etc.)
Hazard control through processing and preservation technologies for enhancing the food safety management of infant food chains
Food safety of infant foods is of paramount importance due to the high vulnerability of this population. Food business operators guarantee safety of the products they put on the market by implementing control measures that ...
Bacteria as Biological Control Agents of Plant Diseases
Biological control is an effective and sustainable alternative or complement to conventional pesticides for fungal and bacterial plant disease management. Some of the most intensively studied biological control agents are ...
Maleic Anhydride Polylactic Acid Coupling Agent Prepared from Solvent Reaction: Synthesis, Characterization and Composite Performance
In the present work, a functionalization of polylactic acid (PLA) has been carried out to anchor maleic anhydride onto the main polymer chain to promote improvement in the compatibility of this polymer matrix with cellulose ...
The Evolution of the Intrinsic Flexural Strength of Jute Strands after a Progressive Delignification Process and Their Contribution to the Flexural Strength of PLA-Based Biocomposites
Biocomposites from poly-(lactic acid) (PLA) and jute strands were prepared, and their flexural strength was analyzed. Jute strands were submitted to a progressive delignification process and the resulting morphology, ...
Tubular photo-MFC reactors as wastewater polishing treatment step with simultaneous electricity production
Wastewater treatment processes energy and emissions issues led researchers to investigate more sustainable alternative technologies, aimed at achieving effective contaminants removal with simultaneous resources recovery ...
Bio-electro CO2 recycling platform based on two separated steps
The present work assessed the alliance of microbial electrochemical technologies (METs) and fermentation in a two-step process for the electro-bioconversion of carbon dioxide (CO2) into elongated chemical building blocks. ...
Applications of agro-hydrological sensors and models for sustainable irrigation
In the last two decades, research on water resource monitoring and management has mainly been aimed at reducing irrigation water volume and energy consumption. At the same time, the effects of climate change and agricultural ...
Media filter fouling assessment using optical coherence tomography: New methodology
Drip irrigation is an efficient and safe system for reusing wastewater in agriculture. Since emitter clogging is its main limitation, filtration is needed for preventing it. Media filters are commonly used when irrigation ...
Characterization of CaCO3 Filled Poly(lactic) Acid and Bio Polyethylene Materials for Building Applications
Noise pollution has been identified as a cause of a broad spectrum of diseases, motivating researchers to identify building materials capable of attenuating this pollution. The most common solution is the use of gypsum ...
Innovative system based on natural polyelectrolyte complex and cellulose micro/nanofibers to improve drainability and properties of recycled paper
In this work, the efficiency of a polyelectrolyte complex (PEC) to retain different cellulose micro/nanofibers (CMNFs) during paper formation and to improve the physical properties of recycled unbleached fiber paper was ...
Solid removal across the bed depth in media filters for drip irrigation systems
Pressurized sand media filters are commonly used in drip irrigation systems to prevent emitter clogging. However, the performance of these filters may be improved with more information about the retention of solids at ...
Thermodynamic approach to foresee experimental CO2 reduction to organic compounds
Anaerobic gas fermentation is a promising approach to transform carbon dioxide (CO2) into chemical building blocks. However, the main operational conditions to enhance the process and its selectivity are still unknown. The ...
Comparative Evaluation of the Stiffness of Abaca-Fiber-Reinforced Bio-Polyethylene and High Density Polyethylene Composites
The use of bio-based matrices together with natural fibers as reinforcement is a strategy for obtaining materials with competitive mechanical properties, costs, and environmental impacts. However, bio-based matrices, unknown ...
Physicochemical and techno-functional properties of dried and defatted porcine liver
Nowadays, there is increasing interest in developing strategies for the efficient and sustainable use of animal by-products, such as pork liver. In order to stabilize the product, a prior dehydration stage may be required ...
