Delimited Massively Parallel Algorithm based on Rules Elimination for Application of Active Rules in Transition P Systems

In the field of Transition P systems implementation, it has been determined that it is very important to determine in advance how long takes evolution rules application in membranes. Moreover, to have time estimations of rules application in membranes makes possible to take important decisions related to hardware/software architectures design. The work presented here introduces an algorithm for applying active evolution rules in Transition P systems, which is based on active rules elimination. The algorithm complies the requisites of being nondeterministic, massively parallel, and what is more important, it is time delimited because it is only dependant on the number of membrane evolution rules

On the occurrence of Zenopsis conchifer (Lowe, 1852) (Osteichthyes, Zeidae) in the Mediterranean Sea

Sobre la presència de Zenopsis conchifer (Lowe, 1852) (Osteichthyes, Zeidae) al mar Mediterrani S’informa de la captura de quatre exemplars de Zenopsis conchifer, espècie que va ser citada per primera vegada al Mediterrani l’any 2007, a las costes de la península Ibèrica. Un dels exemplars va ser capturat prop de l’estret de Gibraltar, per la qual cosa probablement es tractava d’un individu errant. Malgrat aquestes captures no hi ha evidència de l’existència d’una població estable, raó per la qual l’espècie ha de continuar sent considerada com a exòtica al Mediterrani.The capture of four specimens of Silvery John Dory (Zenopsis conchifer),a species recorded in the Mediterranean Sea for the first time in 2006, is reported from the Iberian coast (western Mediterranean). One of the specimens was caught near the Strait of Gibraltar and is probably a vagrant. Despite these catches, there is no evidence of a self–sustaining population, so this species should be considered as alien in the Mediterranean.Sobre la presencia de Zenopsis conchifer (Lowe, 1852) (Osteichthyes, Zeidae) in el Mar Mediterráneo Se informa de la captura de cuatro ejemplares de Zenopsis conchifer, especie cuya primera cita en el Mediterráneo data del año 2007, en las costas de la península ibérica.

Review and Analysis of Models for a European Digital Building Logbook

The concept of a Digital Building Logbook (DBL) was first introduced with the European strategy ‘Renovation Wave’. It is considered as one of two fundamental parts of which the Building Renovation Passport is composed: the DBL and a Renovation Roadmap. As the implementation of the DBL is a European priority, this paper reviews the existing literature and analyses the most developed European Digital Building Logbook models. The analysis includes iBRoad, ALDREN, X-tendo, and the Study on the Development of a European Union Framework for Buildings’ Digital Logbook, from the perspective of seven key aspects: References used as a starting point for the model definition; Identification of the relevant stakeholders in the DBL; Identified potential user needs; Proposed structure of indicators; Data sources; Potential functionalities; and Operation and use. The results show that important advancement has been made, although there is still no consensus about crucial subjects, such as the indicators to be collected or how to collect and use them. This is probably due to the fact that the final functionalities (objective and scope) that the logbook should provide are not fully clear. © 2022 by the authors. Licensee MDPI, Basel, Switzerland

Empleo de isótopos ambientales para discernir la contaminación salina de la cuenca del río Llobregat

La formación geológica salina de la comarca del Bages(Barcelona) y su explotación minera en diferentes puntos de la cuenca del Llobregat, influyen en la salinización de los ríos Cardener y Llobregat. La cuenca potásica catalana presenta dos peculiaridades: la formación salina tiene un afloramiento en Cardona, y en algunas zonas las capas de mineral se encuentran cerca de la superficie pero sin aflorar. La geología del terreno puede influir en la salinidad de las aguas de la cuenca por contacto directo con los materiales salinos. La actividad minera de Cardona (cerrada en 1990), Suria,Balsareny y Sallent, genera en la producción del mineral un residuo salino que se acumula en el exterior de las minas formándose las escombreras salinas o «runams». Sus salessolubles se disuelven con la lluvia, y pueden llegar a las aguas superficiales y aguas subterráneas del entorno. El objetivo de este trabajo es evaluar las aportaciones salinas a la cuenca del río Llobregat, separando las de origen natural y las de procedencia antrópica, utilizando la composición isotópica del azufre y del oxigeno del sulfato disuelto en sus aguas. También se cuantifica el origen natural y antrópico de los cloruros que se aportan

In silico logistic model for table olive related microorganisms as a function of sodium metabisulphite, cinnamaldehyde, pH, and Type of acidifying agent

A probabilistic/logistic model, based on binary data (growth/no growth), was used to assess the effects of sodium metabisulphite (SM) and cinnamaldehyde (CIN; 0-1000 mg/L) against the main microbial groups found in table olive environment [lactic acid bacteria (LAB), yeasts, and Enterobacteriaceae], according to pH (range 3.5-5.0), and type of acidifying agent (HCl or pyruvic acid). The inhibitory effect of SM depended on the pH while that of CIN was scarcely influenced by it (except for LAB). LAB were more sensitive to SM, while yeasts were to CIN. The use of pyruvic acid for correction of pH always produced a reduction (compared to HCl) of the inhibitory power of both preservatives. The in silico models for HCl showed that, at pH 4.0, and growth probability 0.01, the LAB population might be inhibited by the presence in the medium of 150 mg/L SM or 1000 mg/L CIN, while in the case of yeasts, 450 mg/L SM, or 150 mg/L CIN are required. No growth of Enterobacteriaceae was observed at this (or lower) pH level. The results obtained may contribute to the stabilization of non-thermally treated table olive packaging.This research has received funding from INTERACEITUNA (Organización Interprofesional de la Aceituna de Mesa, Spain) and the Junta de Andalucía.

Fast Linear Algorithm for Active Rules Application in Transition P Systems

Transition P systems are computational models based on basic features of biological membranes and the observation of biochemical processes. In these models, membrane contains objects multisets, which evolve according to given evolution rules. In the field of Transition P systems implementation, it has been detected the necessity to determine whichever time are going to take active evolution rules application in membranes. In addition, to have time estimations of rules application makes possible to take important decisions related to the hardware/software architectures design. In this paper we propose a new evolution rules application algorithm oriented towards the implementation of Transition P systems. The developed algorithm is sequential and, it has a linear order complexity in the number of evolution rules. Moreover, it obtains the smaller execution times, compared with the preceding algorithms. Therefore the algorithm is very appropriate for the implementation of Transition P systems in sequential devices

Unemployment and Fertility: A Long Run Relationship.

The paper examines the relationship between the unemployment rate and the fertility rate in a number of European countries along with Japan and the US. We use fractional integration and cointegration techniques to establish this long run relationship. The analysis shed some light on the degree of persistence of the series, and on whether policy actions are required for highly persistent series. The evidence suggests that these two variables (unemployment and fertility rates) are not related in the long run. However, in the short run, assuming that unemployment rate is weakly exogenous, the coefficient relating the two variables is found to be negative in four countries: the Netherlands, Portugal, Spain and the US.pre-print315 K

Assessment of weed control via foliar application of quinate

En estudios previos se detectó una importante acumulación de quinato en la parte aérea de las plantas tratadas con herbicidas inhibidores de la biosíntesis de aminoácidos, lo que podría explicar su capacidad de inducir la respuesta tóxica. También se evaluó el potencial efecto fitotóxico en función del modo de aplicación exógena, que fue superior tras aplicaciones radicales que foliares. En este trabajo se planteó valorar la utilización del quinato, pulverizado exógenamente, para el control del crecimiento de ciertas malas hierbas. Se realizaron aplicaciones foliares de quinato mediante pulverización en post-emergencia sobre plantas en diferentes estados fenológicos de “Sinapis alba”, “Papaver rhoeas”, “Lolium rigidum”, “Bromus diandrus” y “Cynodon dactylon”. Los resultados muestran que dicho compuesto presentó un mayor control y un efecto fitotóxico más evidente en las especies dicotiledóneas que en las monocotiledóneas, siendo “P. rhoeas” la única especie susceptible de ser controlada en sus estadios iniciales con este compuesto. En “S. alba” únicamente se produjo una reducción temporal del crecimiento sin llegar a ser letal.In previous studies quinate was accumulated in leaves of plants treated with amino acid biosynthesis inhibiting herbicides, which begged the question of whether quinate have the capacity of inducing the toxic effects of the herbicides. The phytotoxic effects of exogenous application were more evident when quinate was applied to the nutrient solution than when it was sprayed onto the foliage. The objective of this study was to evaluate whether sprayed quinate could control the growth of some weed species. This was evaluated by spraying quinate to the leaves of plants of “Sinapis alba”, “Papaver rhoeas”, “Lolium rigidum”, “Bromus diandrus” and “Cynodon dactylon” at different phenological states in postemergence. Exogenous application of quinate was more phytotoxic on dicotyledonous species than monocotyledonous species. “Papaver rhoeas” was the only species tested that would be potentially affected and controlled with the application of quinate, specifically in the initial states of plant development. Growth of “S. alba” was only temporally arrested after quinate application, but the treatment was not lethal
