Advanced stitching technology
In the design of textile composites, the selection of materials and constructional techniques must be matched with product performance, productivity, and cost requirements. Constructional techniques vary. A classification of various textile composite systems is given. In general, the chopped fiber system is not suitable for structural composite applications because of fiber discontinuity, uncontrolled fiber orientation and a lack of fiber integration or entanglement. Linear filament yarn systems are acceptable for structural components which are exposed to simple tension in their applications. To qualify for more general use as structural components, filament yarn systems must be multi-directionally positioned. With the most sophisticated filament winding and laying techniques, however, the Type 2 systems have limited potential for general load-bearing applications because of a lack of filament integration or entanglement, which means vulnerability to splitting and delamination among filament layers. The laminar systems (Type 3) represented by a variety of simple fabrics (woven, knitted, braided and nonwoven) are especially suitable for load-bearing panels in flat form and for beams in a roled up to wound form. The totally integrated, advanced fabric system (Type 4) are thought to be the most reliable for general load-bearing applications because of fiber continuity and because of controlled multiaxial fiber orientation and entanglement. Consequently, the risk of splitting and delamination is minimized and practically omitted. Type 4 systems can be woven, knitted, braided or stitched through with very special equipment. Multiaxial fabric technologies are discussed
New extended interpolating operators for hadron correlation functions
New extended interpolating operators made of quenched three dimensional
fermions are introduced in the context of lattice QCD. The mass of the 3D
fermions can be tuned in a controlled way to find a better overlap of the
extended operators with the states of interest. The extended operators have
good renormalisation properties and are easy to control when taking the
continuum limit. Moreover the short distance behaviour of the two point
functions built from these operators is greatly improved. The operators have
been numerically implemented and a comparison to point sources and Jacobi
smeared sources has been performed on the new CLS configurations.Comment: 7 pages, 8 figures. Poster presented at the 34th annual International

STUDIO E SISTEMAZIONE DELLA RETE IDRAULICA NELLA ZONA 'IL PIANO' NEL COMUNE DI CASOLE D'ELSA (SI)
Il presente studio ha lo scopo di determinare le aree allagabili allo “stato attuale”, formulando ipotesi diverse per lo studio idrologico, la costruzione del DTM e le curve di invaso, rispetto a quelle dello Studio Idrologico-Idraulico a supporto alla Variante al Regolamento Urbanistico, confrontandone i risultati ottenuti. Successivamente, osservate le criticità esistenti, sono state ipotizzate le possibili soluzioni al fine di mitigare il rischio idraulico nelle zone interessate da aree edificate e da previsioni di completamento, attraverso una serie di interventi progettuali diffusi, come ad esempio la risagomatura delle sezioni, la riprofilatura del fondo alveo, l’ampliamento degli attraversamenti già esistenti (ponti e tombini), uniti ad interventi volti alla laminazione delle piene, tipo casse di espansione in linea e derivazione.
In sostanza il presente lavoro si articolerĂ nelle seguenti fasi:
- Inquadramento geografico, normativo e storico per la zona oggetto di studio;
- Costruzione del modello idrologico mediante l’utilizzo del software HEC-HMS allo scopo di determinare gli input idrologici da inserire successivamente nello studio idraulico;
- Costruzione del modello idraulico dello “stato attuale” mediante l’utilizzo del software HEC-RAS e successiva determinazione della mappa di allagabilità sia con l’applicazione in ambiente GIS denominata HEC-GeoRAS (metodo oggettivo) che con un metodo manuale (metodo soggettivo);
- Implementazione di varie ipotesi progettuali nel modello idraulico ai fini della mitigazione del rischio idraulico per le aree interessate da insediamenti produttivi come la zona Nord dell’area industriale e nella parte Sud del Piano di Casole, e successiva determinazione della mappa di allagabilità allo Stato di Progetto con un metodo manuale (metodo soggettivo)
Theoretical And Spectroscopic Studies Of Molecular Systems For Charge Transfer And Energy Storage And Transfer
Efficient charge transfer and energy storage and transfer have become increasingly important in many areas of research and development. This is especially true for the development of optoelectronic devices, molecular electronics, and solar voltaic cells. Characterization of the photophysical properties of new molecular systems for these applications has emerged as an important field of research. Many molecular building blocks have been developed and understanding the properties of these systems at a fundamental level is essential for their successful implementation. This dissertation focuses on experimental and theoretical studies of some of these newly-developed molecular systems. Oxygen substituted dihydrobenzvalene is studied theoretically for potential use in energy storage applications. Spectroscopic studies center around the study of newly-developed molecules based on perylene and thiophene derivatives for device applications including nonlinear optics, photovoltaic cells, and molecular electronics. The importance of the synergy between theory and experiment is also demonstrated in the area of chemical education

Servant Leadership in Higher Education: The Influence of Servant-Led Faculty on Student Engagement
Franciscan education has a long tradition of educating the whole student—educating to make better citizens. The focus of this research was to examine the success of that tradition, namely, whether a positive correlation exists between servant leadership of faculty members and higher levels of engagement with their students. Full-time professors at three Franciscan institutions of higher education completed the Servant Leadership Questionnaire (SLQ), which measures participants’ level of servant leadership, and the Faculty Survey of Student Engagement (FSSE), which measures the engagement of the students with faculty. The results of the SLQ and FSSE were organized to answer two research questions: (1) To what extent do faculty in these institutions exhibit the qualities of servant leadership? (2) Among full-time professors teaching at Franciscan institutions of higher education, what is the relationship between servant leadership and deep approaches to learning? This study captured the effects of self-identified faculty “servant ” leaders and their potential to encourage deeper approaches to learning for students, with the hope of creating an environment more squarely within the Franciscan tradition of this learning community. The study’s results indicated a link between servant leadership and deep approaches to learning with a strong correlation to emotional healing.

Machine Learning Toxicity Prediction: Latest Advances by Toxicity End Point
Machine learning (ML) models to predict the toxicity of small molecules have garnered great attention and have become widely used in recent years. Computational toxicity prediction is particularly advantageous in the early stages of drug discovery in order to filter out molecules with high probability of failing in clinical trials. This has been helped by the increase in the number of large toxicology databases available. However, being an area of recent application, a greater understanding of the scope and applicability of ML methods is still necessary. There are various kinds of toxic end points that have been predicted in silico. Acute oral toxicity, hepatotoxicity, cardiotoxicity, mutagenicity, and the 12 Tox21 data end points are among the most commonly investigated. Machine learning methods exhibit different performances on different data sets due to dissimilar complexity, class distributions, or chemical space covered, which makes it hard to compare the performance of algorithms over different toxic end points. The general pipeline to predict toxicity using ML has already been analyzed in various reviews. In this contribution, we focus on the recent progress in the area and the outstanding challenges, making a detailed description of the state-of-the-art models implemented for each toxic end point. The type of molecular representation, the algorithm, and the evaluation metric used in each research work are explained and analyzed. A detailed description of end points that are usually predicted, their clinical relevance, the available databases, and the challenges they bring to the field are also highlighted.Fil: Cavasotto, Claudio Norberto.
