Immunochemical method for penthiopyrad detection through thermodynamic and kinetic characterization of monoclonal antibodies.

2021

Immunoassays are nowadays being employed for rapid contaminant analysis in clinical, environmental, and agrochemical samples. A thorough characterization of the antibody‒antigen interaction can bring light to the immunoreagent selection process in order to develop sensitive and robust tests. Thus, determination of equilibrium and reaction rate constants is usually recommendable. However, this can be quite tricky for low molecular weight compounds, and competitive strategies are commonly followed to estimate apparent affinity values. In the present study, a collection of monoclonal antibodies to penthiopyrad was raised for the first time, and apparent equilibrium constants were assessed by t…

Influencia de la edad y de la posición operatoria sobre las características fisiológicas de la ventilación mecánica en pacientes sometidos a cirugía …

2017

1.- INTRODUCCIÓN. Según los últimos datos demográficos, el nivel más alto de envejecimiento en la Comunidad Europea se alcanzará entre los años 2.010 y 2.020. Para ese momento se prevé que el número de personas de 50 - 64 años se haya incrementado un 26%, que el número de personas mayores de 65 años constituya aproximadamente el 30% de la población, y que el número de personas de 20-29 años descienda un 20%. Por otra parte, desde el punto de vista fisiológico y en relación con la ventilación, los ancianos presentan una serie de características ventilatorias específicas, tanto a nivel de la mecánica ventilatoria como del intercambio gaseoso, que son propias de la edad y que no deben confundi…

Production technologies in stochastic continuous time models

2011

Abstract Properties of dynamic stochastic general equilibrium models can be revealed by either using numerical solutions or qualitative analysis. Very precise and intuition-building results are obtained by working with models which provide closed-form solutions. Closed-form solutions are known for a large class of models some of which, however, have some undesirable features such as potentially negative output. This paper offers closed-form solutions for models which are just as tractable but do not suffer from these shortcomings.

Solving Two-Person Zero-Sum Stochastic Games With Incomplete Information Using Learning Automata With Artificial Barriers

2021

Learning automata (LA) with artificially absorbing barriers was a completely new horizon of research in the 1980s (Oommen, 1986). These new machines yielded properties that were previously unknown. More recently, absorbing barriers have been introduced in continuous estimator algorithms so that the proofs could follow a martingale property, as opposed to monotonicity (Zhang et al., 2014), (Zhang et al., 2015). However, the applications of LA with artificial barriers are almost nonexistent. In that regard, this article is pioneering in that it provides effective and accurate solutions to an extremely complex application domain, namely that of solving two-person zero-sum stochastic games that…

Scheduling Domestic Shiftable Loads in Smart Grids: A Learning Automata-Based Scheme

2017

In this paper, we consider the problem of scheduling shiftable loads, over multiple users, in smart grids. We approach the problem, which is becoming increasingly pertinent in our present energy-thirsty society, using a novel distributed game-theoretic framework. From a modeling perspective, the distributed scheduling problem is formulated as a game, and in particular, a so-called “Potential” game. This game has at least one pure strategy Nash Equilibrium (NE), and we demonstrate that the NE point is a global optimal point. The solution that we propose, which is the pioneering solution that incorporates the theory of Learning Automata (LA), permits the total supplied loads to approach the p…

La circolazione dei modelli a stampa nell'architettura di età moderna

2013

Lo studio del ruolo operativo delle incisioni per la professione di progettista nell’età moderna non ha sempre goduto di una adeguata attenzione.La gerarchia, che in qualche modo siamo abituati a riconoscere come indiscutibile, tra chi inventa e chi copia costituisce senza dubbio un deterrente.Su un fronte diverso, si potrebbero ricordare banalmente quali siano le prerogative vincenti delle incisioni. La comprensione e assimilazione delle stampe si esercita in buona parte a prescindere dal grado di acculturazione del fruitore. La principale dote delle immagini a stampa si fonda sulla costituzione di un metalinguaggio, estraneo agli ostacoli che possono porre gli idiomi nazionali e la loro c…

Libri, incisioni e immagini di architettura come fonti per il progetto in Italia

2013

I saggi proposti in questo volume, elaborati nell’ambito del progetto Prin (2008) da studiosi dell’unità di Palermo e non, intendono affrontare il ruolo delle immagini (incisioni, stampe e disegni) nella prassi progettuale di eta' moderna e relazionare l’architettura costruita con i testi e le incisioni prodotti nell'ambito temporale considerato (XVI- XVIII secolo). Per gli architetti le incisioni costituiscono infatti una risorsa di suggestioni per articolare risposte convincenti alle richieste della committenza. L'analisi delle prassi costruttive ha fatto risaltare il ruolo assunto da una manualistica di settore classificata come raccolte di "porte e finestre". I contributi affrontano app…

Complex Formation of the Uranyl (UO22+) Ion with the Diethylene Triaminopentaacetate (DTPA) Ligand at 25 °C in 3 M Sodium Perchlorate

2011

The complex formation between the uranyl (UO22+) ion and the diethylene triaminopentaacetate ligand (DTPA) has been investigated at 25 °C, in a 3 M sodium perchlorate medium. The overall protonation constants βjH of the free ligand have been previously determined in this ionic medium: six protonated species (HjA), with j ranging from 1 to 6, together with the free anion A5− have been identified in the concentration range from (3·10−3 to 13·10−3) mol·kg−1. Four complex species, H2UO2A−, HUO2A2−, UO2A3−, and UO2AOH4−, have been identified in the total uranyl concentration range from (1.1·10−3 to 5.7·10−3) mol·kg−1, and their overall stability constants determined, keeping the metal to ligand …
