Synthesis and characterization of ethylene-1-hexene copolymers prepared by using MgCl2(THF)2-supported Ziegler-Natta catalysts

2000

Ethylene was copolymerized with 1-hexene over vanadium (VOCl3 and VCl4) and titanium (TiCl4) catalysts supported on MgCl2(THF)2 and activated with Et2AlCl. So far these catalyst systems have not been known as initiators of ethylene-1-hexene copolymerization. The vanadium catalysts were more active than the titanium catalyst and, at identical comonomer concentrations in the feed, gave rise to a greater incorporation of 1-hexene into the copolymer. Even at relatively low fractions of 1-hexene, the MgCl2(THF)2-supported catalysts affected much the copolymer properties like density, melting point and crystallinity.

Artificial intelligence in the diagnosis of pediatric allergic diseases.

2020

Abstract: Artificial intelligence (AI) is a field of data science pertaining to advanced computing machines capable of learning from data and interacting with the human world. Early diagnosis and diagnostics, self-care, prevention and wellness, clinical decision support, care delivery, and chronic care management have been identified within the healthcare areas that could benefit from introducing AI. In pediatric allergy research, the recent developments in AI approach provided new perspectives for characterizing the heterogeneity of allergic diseases among patients. Moreover, the increasing use of electronic health records and personal healthcare records highlighted the relevance of AI in …

Argumentation in the Context of High School Mathematics : Examining Dialogic Aspects of Argumentation

2022

In this chapter, I examine argumentation from the perspective of dialogic argumentation that highlights students’ engagement with each other’s ideas in the process of making mathematical claims and providing evidence to support them. I analyzed the provided data for students’ dialogic and justifying moves and investigated how the teacher supported argumentation. I found that the students’ dialogic moves included elaborating and commenting on peers’ ideas. Students’ justifying moves included one case of articulating reasoning and several instances of describing support. The teacher structured argumentation by sequencing it into steps so that each step established a new piece of information. …

The difficulties of adapting university teaching for students with disabilities : an analysis focussed on inclusive guidance

2012

The need for specific attention for the personal, social, academic and professional development of students with disabilities is a challenge that the university is committed to. Although significant progress has been made, promoted by an inclusive educational approach, there are still many difficulties faced by students to intergrate into university education. To advance a deeper understanding of the issues affecting these students, research has been conducted with a sample of 113 students with disabilities from different centers in the University of La Laguna (Spain). The results have highlighted, the lack of guidance and information regarding access to university courses, the need to impl…

ll TPACK (Technological Pedagogical Content Knowledge) e la formazione dei docenti di sostegno

2021

Questo contributo focalizza l’attenzione sulle competenze dei docenti di sostegno in formazione iniziale cosi come vengono descritte nel framework del Technological Pedagogical Con- tent Knowledge (TPCK – Koehler & Mishra, 2006), a partire dagli studi di Shulman (1986) sul PCK e intende offrire alcune riflessioni metodologiche sulla formazione dell’insegnante di sostegno. I risultati ottenuti con un campione di 1591 docenti iscritti al corso di specializzazione per il sostegno dell’Università degli Studi di Palermo e le riflessioni provenienti dal modello TPACK potrebbero consentire di adeguare le attività formative relative alle TIC alle reali competenze iniziali dei corsisti, contri…

Tailoring oxide properties: An impact on adsorption characteristics of molecules and metals

2014

Abstract Both density functional theory calculations and numerous experimental studies demonstrate a variety of unique features in metal supported oxide films and transition metal doped simple oxides, which are markedly different from their unmodified counterparts. This review highlights, from the computational perspective, recent literature on the properties of the above mentioned surfaces and how they adsorb and activate different species, support metal aggregates, and even catalyse reactions. The adsorption of Au atoms and clusters on metal-supported MgO films are reviewed together with the cluster׳s theoretically predicted ability to activate and dissociate O 2 at the Au–MgO(100)/Ag(100…

The role of expert evaluation for microsleep detection

2015

Abstract Recently, it has been shown by overnight driving simulation studies that microsleep density is the only known sleepiness indicator which rapidly increases within a few seconds immediately before sleepiness related crashes. This indicator is based solely on EEG and EOG and subsequent adaptive pattern recognition. Accurate microsleep recognition is very important for the performance of this sleepiness indicator. The question is whether expensive evaluations of microsleep events by a) experts are necessary or b) non-experts provide sufficient evaluations. Based on 11,114 microsleep events in case a) and 12,787 in case b) recognition accuracies were investigated utilizing (i) artificia…

Perceived support in e-collaborative learning: An exploratory study which make use of synchronous and asynchronous online-teaching approaches

2012

Published version of a chapter in the book: Advances in Web-Based Learning - ICWL 2012. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-33642-3_2 This study compares four different learning environments for e-collaborative learning in two European countries related to the dimension of student’s mutual support. The theoretical baseline is Vygotsky’s zone of proximal development (ZOPD) and the socio-genetic approach of Piaget. The analyzed data are based on questionnaires collected over the time period of an entire semester including four different courses at the master’s level. These courses applied different e-collaborative approaches including a variety of tools f…
