Time, atemporality and the Trinitarian nature of God in Plato’s philosophical heritage

The paper addresses an apparently unsolvable philosophical question: can the Christian Dogma of the Trinitarian nature of God be rationally explained? The authors argue that the conflict between fides and ratio can be resolved by a novel interpretation of the concept of time within a new philosophical paradigm: the Purposeful Evolution Theory (PET), where time, as in Plato, is a movable image of Eternity. In this paper, the PET is used to explain the Christian Dogma of Trinity through a deductive reasoning centred on the concept of atemporality. The Purposeful Evolution Theory has strict links with Plato’s philosophy and represents a key for a systematic interpretation of Plato’s unwritten doctrines. The authors argue that Plato’s unwritten doctrines already addressed and partially solved the problem of Eternity and Time, indirectly giving a reason-based explanation of the Trinitarian Nature of God and His Goodness, before it was even revealed

Distribution of Relaxation Times Based on Lasso Regression: A Tool for High-Resolution Analysis of IMPS Data in Photoelectrochemical Systems

Intensity-modulated photocurrent spectroscopy (IMPS) has been largely employed in semiconductor characterization for solar energy conversion devices to probe the operando behavior with widely available facilities. However, the implementation of IMPS data analysis to complex structures, whether based on the physical rate constant model (RCM) or the assumption-free distribution of relaxation times (DRT), is generally limited to a semi-quantitative description of the charge carrier kinetics of the system. In this study, a new algorithm for the analysis of IMPS data is developed, providing unprecedented time resolution to the investigation of μs to s charge carrier dynamics in semiconductor-based systems used in photoelectrochemistry and photovoltaics. The algorithm, based on the previously developed DRT analysis, is herein modified with a Lasso regression method and available to the reader free of charge. A validation of this new algorithm is performed on a α-Fe2O3 photoanode for photoelectrochemical water splitting, identified as a standard platform in the field, highlighting multiple potential-dependent charge transfer paths, otherwise hidden in the conventional IMPS data analysis

Production of serine chymotrypsin - like elastase by aspergillus fumigatus strains

Thirty-four Aspergillus fumigatus strains isolated from air, horse-hair; agricultural soil and human samples were screened to evaluate the production of elastase. Aspergillus fumigatus strains were grown in elastin solid medium, showing a widespread elastin solubilization. However, isolates from human and agricultural soil samples were found to be the highest elastase producers. Then, eight out of 34 strains were grown in four different liquid media, on wich we investigated total and specific proteolytic activity. Results from this experiments suggest that the elastase production is induced by the presence of elastin as a substrate and that the elastase is a chymotrypsin like enzyme. Inhibitory profile showed that the A.fumigatus elastase is a serine proteinase
