Dabisku mikroorganismu asociāciju izmantošana bioūdeņraža iegūšanai no glicerīna
2017
Ražojot ūdeņradi no jēlglicerīna anaerobajā fermentācijā, iegūst atjaunojamu enerģijas nesēju, kā arī lietderīgi izmanto atkritumproduktu – jēlglicerīnu. Šajā darbā pētīta dabisku mikroorganismu asociāciju – ezera dūņu spēja izmantot jēlglicerīnu ūdeņraţa producēšanai, izvērtēta 20°C un 37°C temperatūras ietekme, kā arī salīdzināta jēlglicerīna un analītiskā glicerīna ietekme uz ūdeņraţa iznākumu. Ar masspektrometriju noteikts gāzu sastāvs. Izmantojot mikrobioloģiskās analīzes, noteikta populāciju dinamika un identificētas dominējošās sugas. Novērtēta organisko vielu koncentrācija un sastāvs ar šķidruma hromatogrāfiju un ar ķīmiskā skābekļa patēriņa noteikšanu. Noskaidrots, ka visvairāk ūde…
Per amore e per interesse. Moventi e modelli dell’azione benefica nella riflessione antica
2021
Classical thinkers described sometimes the donor’s move employing some unexpected analogies: Aristotle explains the “benefactor’s love” comparing it to the artist’s love for his artwork, or to the mother’s devotion to her sons. Cicero talks about benivolentia as a permanent and constant affect, very distant from amor adulescentulorum. Seneca, in ben. 1.14, chooses to compare donor’s beneficia amabilia to the behavior of meretrix. The aim of this paper is to recognize the tight bind of love and interest underlying these analogies, and to explain how it could be, after all, a pattern useful for re-thinking the nature of contemporary philanthropy.
La formazione degli insegnanti alla ricerca
2022
Il contributo muove dall’assunto secondo cui la ricerca ha di per sé un valore formativo strategico. Pertanto, dopo aver focalizzato l’attenzione su alcune peculiarità della ricerca empirica in educazione, ci si focalizza sul ruolo della formazione alla ricerca dei docenti, sia in termini di fruizione che di conduzione autonoma, con particolare riferimento alla prospettiva dell’Evidence Based Education (EBE) e alla ricerca-azione.
Estudio de las rutas de biosíntesis de serina en plantas y su interacción con el cambio climático
2022
La L-serina es un aminoácido que forma parte de las proteínas además de participar en los centros catalíticos de estas. También es la precursora de otras moléculas esenciales como nucleótidos y lípidos, y participa en el metabolismo del folato siendo dadora de moléculas de un carbono. A diferencia de los animales, donde solamente existe una ruta de síntesis de serina, las plantas presentan varias rutas metabólicas. Una de ellas, la llamada ruta del Glicolato, está relacionada con la fotorrespiración, y es considerada la más importante a nivel cuantitativo. Hay otras dos rutas no asociadas a la fotorrespiración. Una de ellas es conocida como ruta del Glicerato y no ha sido caracterizada func…
Density flow over networks: A mean-field game theoretic approach
2014
A distributed routing control algorithm for dynamic networks has recently been presented in the literature. The networks were modeled using time evolution of density at network edges and the routing control algorithm allowed edge density to converge to a Wardrop equilibrium, which was characterized by an equal traffic density on all used paths. We borrow the idea and rearrange the density model to recast the problem within the framework of mean-field games. The contribution of this paper is three-fold. First, we provide a mean-field game formulation of the problem at hand. Second, we illustrate an extended state space solution approach. Third, we study the stochastic case where the density …
Distributed $n$-player approachability and consensus in coalitional games
2015
We study a distributed allocation process where, at each time, every player: i) proposes a new bid based on the average utilities produced up to that time, ii) adjusts such allocations based on the inputs received from its neighbors, and iii) generates and allocates new utilities. The average allocations evolve according to a doubly (over time and space) averaging algorithm. We study conditions under which the average allocations reach consensus to any point within a predefined target set even in the presence of adversarial disturbances. Motivations arise in the context of coalitional games with transferable utilities (TU) where the target set is any set of allocations that makes the grand …
Game Theory with Engineering Applications
2016
Engineering systems are highly distributed collective systems—decisions, information, and objectives are distributed throughout—that have humans in the loop, and thus decisions may be influenced by socioeconomic factors. Engineering systems emphasize the potential of control and games beyond traditional applications. Game theory can be used to design incentives to obtain socially desirable behaviors on the part of the players, for example, a change in the consumption patterns on the part of the “prosumers” (producers-consumers) or better redistribution of traffic. This unique book addresses the foundations of game theory, with an emphasis on the physical intuition behind the concepts, an an…
