Nuovo realismo e architettura della città/New realism and architecture of the city

La discussione filosofica sul nuovo realismo, che ha alimentato negli ultimi anni in Italia un ampio dibattito, non solo disciplinare, ha suscitato anche tra gli architetti alcuni interrogativi che riguardano, da un lato, il rapporto tra il mondo delle idee e il mondo degli oggetti fisici e più concretamente tra teoria e pratica dell'architettura e, dall'altro, il ruolo degli architetti e delle opere realizzate rispetto alla elaborazione del pensiero filosofico e speculativo. A questi interrogativi si è cercato di dare risposta in alcuni convegni, svoltisi tra Torino e Napoli nel 2012 e nel 2013, e per non perdere di vista il contatto con la realtà costruita dell'architettura, si è deciso di affiancare alla discussione teorica anche una mostra, con l'obiettivo di affrontare la questione del rapporto tra architettura e realismo anche sul piano delle opere realizzate. In particolare sono state individuate due questioni come il filo rosso che unisce nelle discussioni e nelle realizzazioni architettoniche degli ultimi trent'anni esperienze diverse, nel tempo e nello spazio, in una tensione comune verso la realtà: il rapporto con la città e il rapporto con la storia e la tradizione dell'architettura. A partire da queste due questioni il campo di indagine per questa mostra si è ristretto a tre generazioni di architetti, che poi corrispondono a tre fasi di costruzione della città, e a tre città europee con un impianto storicamente definito e consolidato che ha rappresentato una realtà concreta «inemendabile» con cui i progetti si sono confrontati. Le città scelte sono Amsterdam, Barcellona e Berlino, a cui si sono poi aggiunte come casi-studio, sui quali avviare una riflessione, le città ospiti della mostra, Torino e Napoli. Inoltre, per affrontare direttamente la questione del rapporto tra teoria e pratica dell'architettura, agli architetti sono state rivolte dieci domande, che cercano di mettere in relazione il dibattito filosofico sul nuovo realismo con la questione dell'architettura della città e più in generale aprono un confronto tra la discussione storico-critica e i progetti realizzati, tra la teoria e gli esemp

Veggiecation: A Novel Approach to Improve Vegetable Consumption Among School-Aged Children

Children\u27s general preference for sweeter foods and aversion to bitter vegetables is explained partly by fear of new food and social and cultural influences. Reluctance to eat new foods is related to unfavorable facial expressions and is often learned from the child\u27s family, social circle, and culture.1 Researchers report that the fruit and vegetable consumption of children 6–12 years of age is associated with the accessibility and availability.2 School-based interventions that combine classroom curricula, parental, and nutrition service components show the greatest promise for fruit and vegetable promotion among children

A study of Machine Learning models for Clinical Coding of Medical Reports at CodiEsp 2020

The task of identifying one or more diseases associated with a patient’s clinical condition is often very complex, even for doctors and specialists. This process is usually time-consuming and has to take into account different aspects of what has occurred, including symptoms elicited and previous healthcare situations. The medical diagnosis is often provided to patients in the form of written paper without any correlation with a national or international standard. Even if the WHO (World Health Organization) released the ICD10 international glossary of diseases, almost no doctor has enough time to manually associate the patient’s clinical history with international codes. The CodiEsp task at CLEF 2020 addressed this issue by proposing the development of an automatic system to deal with this task. Our solution investigated different machine learning strategies in order to identify an approach to face that challenge. The main outcomes of the experiments showed that a strategy based on BERT for pre-filtering and one based on BiLSTMCNN-SelfAttention for classification provide valuable results. We carried out several experiments on a subset of the training set for tuning the final model submitted to the challenge. In particular, we analyzed the impact of the algorithm, the input encoding strategy, and the thresholds for multi-label classification. A set of experiments has been carried out also during a post hoc analysis. The experiments confirmed that the strategy submitted to the CodiEsp task is the best performing one among those evaluated, and it allowed us to obtain a final mean average error value on the test set equal to 0.202. To support future developments of the proposed approach and the replicability of the experiments we decided to make the source code publicly accessible

Aerosol Jet Printing of a Benzocyclobutene-Based Ink as Adhesive Material for Wafer Bonding Application

Aerosol jet printing (AJP) is an emerging additive manufacturing technology that is gaining increasing attention in the electronic field. Several studies have been carried out on the AJP of conductive, semiconductive, and dielectric polymers for electronic applications. However, wafer bonding is an application that is still uncovered by literature. Therefore, in this work, the AJP of benzocyclobutene (BCB) as a polymeric adhesive for wafer bonding is presented for the first time. A thorough characterization of the processing parameters is carried out to identify the most ideal conditions for printing at a relatively high speed. Then, square patterns are printed, proving the versatility of the AJP technology in terms of the reachable thickness of the deposited BCB patterns. Complex patterns with a resolution of approximate to 60 mu m are also printed. The bonding properties of the BCB are characterized from a morphological and mechanical point of view. In particular, the shear strength of the BCB coatings deposited with AJP is approximate to 39 MPa and it is comparable with the shear strength of BCB coating deposited by spin-coating. Consequently, AJP represents a valid alternative for the deposition of polymeric adhesive for wafer bonding

Association between functional EGF+61polymorphism and glioma risk

Epidermal growthf actor (EGF) plays a critical role in cancer. A polymorphism in the EGF gene (EGF+61) may influence its expression and contribute to cancer predisposition and aggressiveness. In the present study, we aimed to elucidate the role of EGF+61in glioma susceptibility and prognosis. Experimental Design:A case-control study involving197 glioma patients and 570 controlswas done. Univariate and multivariate logistic regression analyses were used to calculate odds ratio (OR) and 95% confidence intervals (95% CI). False-positive report probability was also assessed.The luciferase reporter gene assay was used to ascertain the functional consequences of this polymorphism. Results: Corroborating the univariate analysis, the multivariate model showed that the G allele conferred higher risks for gliomas (OR,1.32; 95% CI,1.04-1.67), glioblastomas (OR,1.47; 95% CI, 1.02-2.10), and oligodendrogliomas (OR,1.55; 95% CI,1.07-2.23).TheGG genotypeswere associatedwithincreased risk for gliomas (OR,1.71; 95%CI,1.07-2.73), glioblastomas (OR, 2.03; 95% CI, 1.02-4.05), and oligodendrogliomas (OR, 2.72; 95% CI, 1.18-6.28). In addition, the AG+GG genotypes were associated withhigher risk for gliomas (OR,1.52; 95% CI,1.03-2.23) and oligodendrogliomas (OR, 2.80; 95% CI,1.35-5.79). No significant associationwas observed between the EGF+61polymorphism and glioblastoma or oligodendroglioma patients’overall survival. The luciferase reporter gene assay exhibited a significant increased promoter activity for the G variant compared withthe referenceA allele. Conclusions: These findings support the role of the EGF+61polymorphism as a susceptibility factor for development of gliomas and show its implication on EGF promoter activity.Sixth Research Framework Programme of the European Union, Project INCA (LSHC-CT-2005-018704

Analgesic effects of intravenous flunixin and intrafunicular lidocaine or their combination for castration of lambs.

Abstract Objective: To analyse the effectiveness of intrafunicular lidocaine and intravenous flunixin for reducing pain and signs of stress in lambs undergoing surgical castration. Design: Randomised controlled trial. Setting: One university teaching hospital in Italy. Participants: 30 healthy male lambs, 9-12 weeks old. Intervention: Allocation to five groups: a control group (C), undergoing general anaesthesia but not castration; a surgery group (S), undergoing orchiectomy without analgesic treatment; a surgery-lidocaine group (SL), undergoing orchiectomy and receiving intrafunicular 2 per cent lidocaine solution; a surgery-flunixin group (SF), undergoing orchiectomy and receiving intravenous flunixin; a surgery-flunixin-lidocaine group (SFL), undergoing orchiectomy and receiving both intrafunicular lidocaine and intravenous flunixin. Main outcome measures: Nociception and stress were assessed through intraoperative indicators, serum cortisol concentration, glycaemia, behaviour, immune response and clinical evaluation of the heart rate (HR), respiratory rate and rectal temperature after surgery. Results: Groups S and SL showed increased values of intraoperative HR, mean arterial pressure and postoperative cortisol concentration. In group SFL, cortisol values were similar to those of group C. No other difference could be detected. Conclusions: The combination of intravenous flunixin and intrafunicular lidocaine reduced the pain and discomfort of lambs castrated under general anaesthesia. Intrafunicular lidocaine alone did not prevent pain or discomfort associated with castration

Late Pleistocene-Holocene History of Chaco-Pampa Sediments in Argentina and Paraguay

Eine erheblich verbesserte Rekonstruktion der spätpleistozänen/holozänen morphologischen und geologischen Geschichte des paraguayischen Chaco und der argentinischen Pampa Ebene wird vorgestellt. Wegen der großen Ausdehnung des Gebietes waren Satellitenbilder der Schlüssel, um frühere und neue interdisziplinäre geowissenschaftliche Ergebnisse zu einem verlässlicheren Bild zusammenzuführen. Für diesen synoptischen Überblick wurde die Interpretation von Fernerkundungsdaten durch Geländeuntersuchungen und physikalische Altersbestimmungen ergänzt. Viele Lumineszenzalter (75 IRSL und 12 TL) von Löß, lößähnlichen Sedimenten und Sanden wurden bestimmt, die bei der Rekonstruktion der Klimageschichte des Untersuchungsgebiets im Marinen Isotopen Stadium 3 bis 1 (MIS 3–1) beitragen. Lößablagerungen überwiegen in der Zeit vor MIS 2. Die numerische Alter von lakustrinen und alluvialen Sedimenten, im Löß zwischengelagert, belegen wechselnde feuchte und trockene Perioden in der Chaco/Pampa-Ebene im MIS 2 und MIS 1. Überwiegend trockene Bedingungen herrschten von 8.5 bis 3.5 ka BP (mittleres MIS 1), als Sande in Form von Dünen oder in Paläoflussbetten abgelagert wurden. Zeitlich begrenzte Phasen extrem verstärkter Paläoflussaktivität im Mittelholozän wurden auf sporadische Starkregenereignisse in den Anden zurückgeführt. Die Ursprungsgebiete des Löß, der lößartigen Sedimente und der sandigen Ablagerungen wurden in der südwestlichen Pampa, den benachbarten Andenabhängen und im Altiplano lokalisiert. Diese Sedimente wurden von dort nach Osten und später nach Nordosten transportiert, wie sich aus den morphologischen Mustern als Zeugnisse früherer äolischer Aktivität rekonstruieren ließ.researc

Versatile and non-cytotoxic GelMA-xanthan gum biomaterial ink for extrusion-based 3D bioprinting

Extrusion-based 3D bioprinting allows the 3D printing of bioinks, composed of cells and biomaterials, to mimic the complex 3D hierarchical structure of native tissues. Successful 3D bioprinting requires bioinks with specific properties, such as biocompatibility, printability, and biodegradability according to the desired application. In the present work, we aimed at developing a new versatile blend of gelatin methacryloyl-xanthan gum (GelMA-XG) suitable for extrusion-based 3D bioprinting with a straightforward process. To this end, we first optimized the process of gelatin methacryloyl (GelMA) synthesis by investigating the impact of different buffer solutions on the degree of functionalization, swelling degree, and degradation rate. The addition of xanthan gum (XG) enabled further tuning of biodegradability and an improvement of GelMA printability. Specifically, an optimal concentration of XG was found through rheological characterization and printability tests. The optimized blend showed enhanced printability and improved shape fidelity as well as its degradation products turned out to be non-cytotoxic, thus laying the foundation for cell-based applications. In conclusion, our newly developed biomaterial ink is a promising candidate for extrusion-based 3D bioprinting
