Conditions for the joint conversion of CO2 and syngas in the direct synthesis of light olefins using In2O3−ZrO2/SAPO-34 catalyst
(ACS, 2021-11-09)
The conditions for promoting the joint conversion of CO2 and syngas in the direct synthesis of light olefins have been studied. In addition, given the relevance for the viability of the process, the stability of the ...
Adaptation and Validation of the 3 × 2 Achievement Goals Questionnaire in a Population of Athletes
(MDPI, 2024-04-22)
(1) Background: Sport goals, although widely recognised as crucial for motivation and performance in sport, are multifaceted and can be difficult to measure directly. The present research aims to validate the 3 × 2 ...
Testing a vaccine candidate against Hepatitis C virus designed by combinatorial optimization
(Nature, 2023)
This paper presents a new procedure for vaccine design against highly variable viruses such as Hepatitis C. The procedure uses an optimization algorithm to design vaccines that maximize the coverage of epitopes across ...
Diagnosis of the health status of mooring systems for floating offshore wind turbines using autoencoders
(Elsevier, 2023-11)
Floating offshore wind turbines (FOWTs) show promise in terms of energy production, availability, and sustainability, but remain unprofitable due to high maintenance costs. This work proposes a deep learning algorithm to ...
Kinetic modeling and reactor design of the direct synthesis of dimethyl ether for CO2 valorization. A review
(Elsevier, 2022-08-04)
The direct synthesis of dimethyl ether (DME) is considered one of the most attractive routes for valorizing CO2 and syngas on a large scale. DME has a high cetane number and its properties are similar to those of liquefied ...
Shell midden people in northern Iberia. New data from the mesolithic rock shelter of J3 (Basque Country, Spain)
(Ediciones Universidad de Salamanca, 2010)
[EN]In the course of a sondage dug in the rock shelter of J3, in the Jaizkibel mountains (at the north-western tip of Guipúzcoa), the body of a adult man was located buried inside a shell midden. This shell midden had not ...
2D PIV/PTV–3D uRANS RSM Investigation on the Combined Effect of Iron Filings Filtering Techniques in a Backward Facing Step Flow
(Springer, 2023-03)
The presence of suspended particles in liquid fluids is one of the main reasons for hydraulic system failure. Metallic impurities in particular increase the presence of toxic substances in wastewater; therefore, it is vital ...
Upper Palaeolithic hunter–gatherer societies in the Basque Country (Iberian Peninsula) in the light of palaeoenvironmental dynamics in the last Glacial Period: cultural adaptations and the use of biotic resources
(Cambridge University Press, 2023-07)
Upper Palaeolithic archaeological sites in the Basque Country have been excavated for over a century. They have yielded a rich palaeoenvironmental record with zoological and botanical remains that have been obtained in ...
Molecular confirmation of pearl formation in arctic mussels (Mytilus edulis) caused by Gymnophallus bursicola (Odhner 1900) metacercariae
(Cambridge University Press, 2023-09)
In recent field studies, suspected gymnophallid metacercariae were histologically located in the mantle of mussels from the Norwegian Sea. Mussels from the sites in which that infection was detected also presented abnormally ...
Model validation of a packed bed LTA membrane reactor for the direct synthesis of DME from CO/CO2
(2020-10-16)
A model for simulating the direct synthesis of dimethyl ether (DME) in a packed bed membrane reactor (PBMR) has been validated, using a LTA zeolite hydrophilic membrane in a lab-scale reaction equipment. In the model, ...
