A study on the impact of the reaction mechanism of the thermochemical activation of bone char (by pyrolysis and carbonization)
(Elsevier, 2023-05)Porous materials based on bioapatite were prepared through the thermochemical activation of pork bone char, using different reagents (H2SO4 and K2CO3), heating atmosphere (inert and oxidizing) and activation temperature. ... -
A Study on the Modified Form of Riemann-Type Fractional Inequalities via Convex Functions and Related Applications
(MDPI, 2022-12-19)In this article, we provide constraints for the sum by employing a generalized modified form of fractional integrals of Riemann-type via convex functions. The mean fractional inequalities for functions with convex absolute ... -
A Study on the Spontaneous Representation of Animals in Young Children’s Drawings of Plant Life
(MDPI, 2018-04)Previous research indicates that complex biological concepts may be successfully introduced in preschool age, provided that suitable educational interventions are designed for the initial stages of education. In this regard, ... -
A Study Regarding the Representation of the Sun in Young Children’s Spontaneous Drawings
(MDPI, 2017-08-22)Drawing has historically been the preeminent way of portraying the observations of the sun. The study of the early stages of the development of astronomical thought and the examination of human graphic expression indicate ... -
A Survey of Performance Modeling and Simulation Techniques for Accelerator-Based Computing
(IEEE, 2014-02-25)The high performance computing landscape is shifting from collections of homogeneous nodes towards heterogeneous systems, in which nodes consist of a combination of traditional out-of-order execution cores and accelerator ... -
A Survey on IEEE 1588 Implementation for RISC-V Low-Power Embedded Devices
(MDPI, 2024-01-22)IEEE 1588, also known as the Precision Time Protocol (PTP), is a standard protocol for clock synchronization in distributed systems. While it is not architecture-specific, implementing IEEE 1588 on Reduced Instruction Set ... -
A survey on Sign Language machine translation
(Elsevier, 2023-03)Sign Languages (SLs) are employed by deaf and hard-of-hearing (DHH) people to communicate on a daily basis. However, the communication with hearing people still faces some barriers, mainly because of the scarce knowledge ... -
A Survey on the Contributions of Software-Defined Networking to Traffic Engineering
(IEEE, 2017-05-31)Since the appearance of OpenFlow back in 2008, software-defined networking (SDN) has gained momentum. Although there are some discrepancies between the standards developing organizations working with SDN about what SDN is ... -
A survey on the use of mice, pigs, dogs and monkeys as animal models in biomedical research in Spain
(Springernature, 2022)[EN] Background The use of animals in biomedical science remains controversial. An individual's level of concern is generally influenced by their culture, previous or current experience with animals, and the specific animal ... -
A Sustainable Material for Sheep’s Cheese Wedges Stored under Different Atmosphere Conditions
(MDPI, 2024-05-06)This study is based on the need to improve packaging sustainability in the food industry. Its aim was to assess the performance of a recyclable plastic material for semi-hard sheep’s cheese wedges packaging as an alternative ... -
