Prediction of acute toxicity of phenol derivatives using multiple linear regression approach for Tetrahymena pyriformis contaminant identification in…
2016
In this article, the modeling of inhibitory grown activity against Tetrahymena pyriformis is described. The 0-2D Dragon descriptors based on structural aspects to gain some knowledge of factors influencing aquatic toxicity are mainly used. Besides, it is done by some enlarged data of phenol derivatives described for the first time and composed of 358 chemicals. It overcomes the previous datasets with about one hundred compounds. Moreover, the results of the model evaluation by the parameters in the training, prediction and validation give adequate results comparable with those of the previous works. The more influential descriptors included in the model are: X3A, MWC02, MWC10 and piPC03 wit…
Sviluppo e Innovazione nell'Hi-tech in Sicilia. Un'indagine sulle imprese àncora e sulle reti innovative nell'area di Catania
2011
The purpose of this report is to scrutinize the development of the microelectronics and nanotechnology cluster from an original anchor fi rm perspective and to examine the processes through which the roles of anchors and their networks of relationships with the most important players of the cluster evolved over the last quarter of the century. On the ground of the analysis of archival data, internal documents and reports, academic publications, and personal interviews with key managers, researchers, and crucial actors from both private and public sides – performed coherently with the snowballing method – the report identifi es the emergence and development of the microelectronics and nanote…

Risk Analysis of a Fuel Storage Terminal Using HAZOP and FTA
2017
[EN] The size and complexity of industrial chemical plants, together with the nature of the products handled, means that an analysis and control of the risks involved is required. This paper presents a methodology for risk analysis in chemical and allied industries that is based on a combination of HAZard and OPerability analysis (HAZOP) and a quantitative analysis of the most relevant risks through the development of fault trees, fault tree analysis (FTA). Results from FTA allow prioritizing the preventive and corrective measures to minimize the probability of failure. An analysis of a case study is performed; it consists in the terminal for unloading chemical and petroleum products, and t…
A root cause analysis method for preventing erratic behavior in software development: PEBA
2019
Measures taken to prevent faults from being introduced or going undetected can secure development of highly reliable software systems. One such measure is analyzing root causes of recurring faults and preventing them from appearing again. Previous methods developed for this purpose have been reactive in nature and relied heavily on fault reporting mechanisms of ogranizations. Additionally, previous efforts lack a defined mechanism for innovating corrective actions. In this study, we strive to complement the existing methods by introducing a proactive and qualitative method that does not rely on fault data. During the course of the research, in addition to an extensive literature search, an …
Re-immaginare il Sud. Le sfide del buongoverno per la metamorfosi dello sviluppo
2014
Gli aspetti strutturali della attuale crisi devono essere affrontati come una metamorfosi dei protocolli di sviluppo, e le conseguenti soluzioni messe in campo devono essere sempre più interconnesse, richiedendo costanti sforzi di comprensione unitaria e chiamando ad una nuova alleanza tra politica ed economia, tra cultura ed ambiente, tra tecnica e società. La crisi ci obbliga a selezionare i capitali dello sviluppo, a riprogettare i percorsi, a darci nuove regole e a trovare nuove forme di impegno e di compartecipazione. La crisi diventa così occasione reale di discernimento e di nuova progettualità, poiché essa ha ormai travalicato i confini settoriali, ha tracimato dagli argini finanzia…
Transformando las prácticas de evaluación en las agencias de innovación para fomentar transiciones hacia la sostenibilidad
2019
The aim of the study is to identify different styles and practices for evaluation of innovation policies based on different orientations, focusing on the case of the paradigm of transformative change to foster transitions towards sustainability, and the problems associated with its application. The study is exploratory, and it uses public funding agencies for innovation as strategic research settings. Based on the information provided by the experience of an international consortium participated by funding agencies from different countries, the main concepts and problems presented in the theoretical debate are illustrated. Finally, the main contributions of the study to the theory and pract…
Interactive Learning Environments (ILEs) as Effective Tools for Teaching Social Sciences
2016
Schoolteachers could enhance learning in social science courses by using teaching tools that favour a methodological approach focused on the topics' basic structure rather than on facts. An innovative system dynamics social-based ILE built with a social constructivist approach is presented here. The pedagogical futures of this ILE are then analysed. The effective impact of different instructional approaches inspired by social-based ILEs on student learning outcomes is also discussed. The ILE and the related inquiry-based instructional approach seem to help students understand fundamental concepts more easily, thus making the topic more comprehensible and helping students place the social fa…
Security framework for dynamic service-oriented IT systems
2018
The paper proposes a framework for dynamic service-oriented IT systems security. We review the context of service-oriented architecture (SOA), which constitutes a paradigm of dynamic system configuration including security constraints at the system module development stage, supporting with the domain-driven resources, carrying out routine SOA maintenance and implementing XML-compatible parsing technologies in order to improve the system performance. Likewise, we discuss the fundamental differences between security management systems with traditional centralized and monolithic architecture and service-oriented IT systems from the perspective of security-related issues. Web services security …
Metabolic response of bacteria to elevated concentrations of glyphosate-based herbicide.
2019
Abstract Glyphosate-based herbicides (GBHs) are the most widespread commonly used broad-spectrum herbicides that contaminate soils and waters, are toxic to bacteria, plants and animals, and have been classified as ‘probably carcinogenic to humans’ by the International Agency for Research on Cancer in 2015. Particular soil bacteria and fungi can degrade GBHs, hence, search for new GBH-degrading strains or microbial consortia, effective under specific growth conditions and local environment, seems to be a promising solution for bio-remediation of glyphosate-contaminated environment. Consequently, there is a need for rapid and informative methods to evaluate the GBH-induced changes of the meta…
