New extended thermodynamics balance equations for an electron gas confined in a metallic body
Full text linkSommerfeld’s theory of metal electrons suggests that the electrons in a metal can be described as a gas of free fermion particles confined inside the metallic body. In this paper a new extended thermodynamics model is proposed starting from this idea. The model includes both the stress tensor and a quadratic expansion of the distribution function in the neighborhhod of an equilibrium state. Such contributions were neglected in the original model proposed by Müller in 1976; so this new set of balance laws represents an improvement aimed at the description of non-equilibrium phenomena. The application to a simple case is briefly analysed

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Diazotrophic Cyanobacteria for Protein Production: Hotorespirometry to Assess the Effect of Light and Temperature
No full textProtein production, thriving on the chemical fixation of nitrogen in fertilizers and intensive use of agricultural and livestock practices, significantly compromises environmental sustainability. The need for alternative food resources to meet the raised demand due to the fast-growing global population has turned pressing. Diazotrophic cyanobacteria, capable of converting atmospheric nitrogen into bioavailable forms, offer promise in sustainable protein production, bypassing traditional inefficiencies. Such microorganisms’ potential might be fully exploited if the production process is well-characterized and controlled. The primary objective of this study is to investigate the specific effects of light and temperature on the growth dynamics of Nostoc PCC 7120 by using photorespirometry. The study aims to retrieve kinetic parameters essential for predictive modeling in industrial applications. The optimal light intensity (376 μmol m-2 s-1) was estimated, as well as the optimal temperature. The latter showed to be dependent on culture conditions: under nitrogen-fixing conditions, it drops from 30 to 27 °C, highlighting temperature-driven effects based on the nitrogen source
