Involvement of nitrate reductase and pyoverdine in competitiveness of Pseudomonas fluorescens strain C7R12 in soil

2001

ABSTRACT Involvement of nitrate reductase and pyoverdine in the competitiveness of the biocontrol strain Pseudomonas fluorescens C7R12 was determined, under gnotobiotic conditions, in two soil compartments (bulk and rhizosphere soil), with the soil being kept at two different values of matric potential (−1 and −10 kPa). Three mutants affected in the synthesis of either the nitrate reductase (Nar − ), the pyoverdine (Pvd − ), or both (Nar − Pvd − ) were used. The Nar − and Nar − Pvd − mutants were obtained by site-directed mutagenesis of the wild-type strain and of the Pvd − mutant, respectively. The selective advantage given by nitrate reductase and pyoverdine to the wild-type strain was as…

This Master’s thesis of general history focuses on the social interaction between ethnic Finns and Native Americans in North America c. 1850—1950. The research aims to cover the nature of the interaction phenomenon in question as well as the social statuses of both groups and the attitudes expressed by them concerning the other. The analysis is based on biographical source material supported by documents, interviews and academic literature emphasizing both the Finns and the Native Americans who were in contact with each other during the aforementioned era. The analysis conducted in this thesis highlights that the majority of the interaction between Finns and Native Americans took place in t…

A Connectionist Extension of Kintsch's Construction-Integration Model

2006

This paper proposes an extension to Kintsch"s Construction Integration mode of text comprehension, which changes its mathematical implementation and emphasizes the connectionist features of the model. Specifically, the extension proposed here a) simulates the learning process in a connectionist manner by making explicit changes in the connecting values among processing units; b) takes into account individual differences in prior background knowledge activation and individual ability to make logical inferences, using these parameters to adjust the results of the simulation; and c) implements an algorithm that constructs the connectivity matrix W from text processing. The proposed extension i…

Inverse estimation of terminal connections in the cardiac conduction system

2018

Modeling the cardiac conduction system is a challenging problem in the context of computational cardiac electrophysiology. Its ventricular section, the Purkinje system, is responsible for triggering tissue electrical activation at discrete terminal locations, which subsequently spreads throughout the ventricles. In this paper, we present an algorithm that is capable of estimating the location of the Purkinje system triggering points from a set of random measurements on tissue. We present the properties and the performance of the algorithm under controlled synthetic scenarios. Results show that the method is capable of locating most of the triggering points in scenarios with a fair ratio bet…

Environmental Noise and the Cardiovascular System

2018

Abstract Noise has been found associated with annoyance, stress, sleep disturbance, and impaired cognitive performance. Furthermore, epidemiological studies have found that environmental noise is associated with an increased incidence of arterial hypertension, myocardial infarction, heart failure, and stroke. Observational and translational studies indicate that especially nighttime noise increases levels of stress hormones and vascular oxidative stress, which may lead to endothelial dysfunction and arterial hypertension. Novel experimental studies found aircraft noise to be associated with oxidative stress–induced vascular damage, mediated by activation of the NADPH oxidase, uncoupling of …

Partecipazione 2.0: l’avatar scende in piazza (paper 6.3.2.)

2011

Al declino della partecipazione elettorale ed alla crisi delle capacità identificanti dei partiti fanno da contrappeso nuove forme di partecipazione politica. I new media in tale contesto hanno un ruolo essenziale sia per i grandi movimenti transnazionali, sia per i comitati locali single issue e per mobilitazioni spontanee caratterizzate dal passare con estrema rapidità dal mondo virtuale alle piazze. Nuove forme di democrazia integrano le democrazie rappresentative. Le tecnologie per la comunicazione e l’informazione hanno un forte impatto sulla definizione dei confini e dell’identità della comunità politica e possono contribuire a trasformare i processi decisionali pubblici, incrementand…
