The Hydraulic Power Generation and Transmission on Agricultural Tractors: Feasible architectures to reduce dissipation and fuel consumption-Part i

This paper is aimed at investigating the benefits in terms of energy efficiency of new electro-hydraulic architectures for power distribution systems of a medium-size agricultural tractor, with a focus on the hydraulic high-pressure circuit. The work is part of a wider industrial research project called TASC (Smart and Clean Agricultural Tractors [1]). Traditional and alternative architectures have been modelled and energetically compared through simulation, using a lumped parameter approach. Experimental data previously acquired have been used to validate the models and to replicate real working conditions of the machine in the simulation environment. A typical on-field manoeuvre has been used as duty cycle, to perform an effective energetic analysis. The standard hydraulic circuit is a multi-users load sensing system that uses a single variable displacement pump to feed steering, trailer brake and auxiliary utilities in that order. The key idea of the proposed solutions is the separation of steering from the other implements, to optimize the entire energy management. In particular, the paper investigates new and flexible solutions for the auxiliary utilities, including an electro-hydraulic load sensing architecture with variable pump margin, an electronic flow matching and flow sharing architecture, and an electronic strategy for automatic pressure compensation. The simulation results show that good energy saving can be achieved with the alternative architectures, so that physical prototyping of the most promising solutions will be realized as next step of the project

La vérité des reliques selon Charles Borromée : réforme interne ou aiguillon protestant ?

Sous le feu des critiques protestantes, le Concile de Trente, au cours de la XXVe et dernière session (3-4 décembre 1563), proclame solennellement la légitimité de la vénération due aux reliques : condamnant toute forme de critique à l’égard du culte des saints et des pèlerinages auprès de leurs corps, il enjoint aux évêques d’enseigner à leurs fidèles « les honneurs dus aux reliques », de réprimer toute forme d’« abus » et de « superstition » et de s’assurer de leur authenticité. Toutefois, dans la mise en œuvre concrète du décret, le contrôle épiscopal des reliques relève plus de l’exigence de réforme interne de l’Église que du combat anti-protestant. Cette contribution met en lumière la place de la réforme interne et de la polémique anti-protestante dans l’interprétation du décret tridentin donnée dans l’archevêché de Milan, pendant l’épiscopat de Charles Borromée (1564- 1584), en prenant en considération la méthode prescrite et quelques exemples de sa pratique de la reconnaissance.

Short Term and Long Term Bioacoustic Monitoring of the Marine Environment. Results from NEMO ONDE Experiment and Way Ahead.

The INFN NEMO-OνDE (Ocean Noise Detection Experiment) station, deployed on the seafloor at 2000 m depth 25 km offshore Catania (Sicily, Italy) in year 2005, was designed to continuously transmit broad-band acoustic data through optical cables to the INFN lab located in the port of Catania. It was operational until November 2006, when it was replaced by other experimental equipment. During the operational period, 5 minutes of recording (4 hydrophones, 45 kHz bandwidth, 96 kHz sampling rate at 24 bits resolution) were taken every hour. The experiment provided long-term data on the underwater noise and an unique opportunity to study the acoustic emissions of marine mammals living in, or transiting through the area east of Sicily. The recordings revealed a more frequent and consistent presence of sperm whales than previously believed

Studi confraternali: orientamenti, problemi, testimonianze

Il volume raccoglie interventi di studiosi italiani e stranieri miranti a offrire una panoramica di percorsi storiografici e di problematiche relativi alla storia del movimento confraternale, così come sono emersi nell'ambito di discipline storiche, sociali, giuridiche, letterarie e artistiche sviluppatesi nel corso del Novecento. I contributi si riferiscono al contesto storico dell'Europa occidentale, con più specifico riguardo per l'Italia, nel periodo compreso fra medioevo e prima età moderna. La raccolta si articola in quattro sezioni: Individui e gruppi, che sonda l'emergere di un interesse verso le comunità confraternali all'interno di ambiti di studio come la storia dei gruppi sociali, del mondo rurale, delle donne, dei giovani; L'inquadramento giuridico e istituzionale, che affronta problemi di legittimità e di assetto istituzionale; L'economia della carità, che analizza il rapporto delle confraternite con gli enti ospedalieri, le modalità amministrative dei patrimoni confraternali, le culture di governo che sottostanno a politiche assistenziali di cui le confraternite sono tramite principale; Testimonianze teatrali, musicali, artistiche, documentarie dedicata alle fonti che le confraternite hanno saputo trasmettere

The PROVENT-C19 registry: A study protocol for international multicenter SIAARTI registry on the use of prone positioning in mechanically ventilated patients with COVID-19 ARDS

Background The worldwide use of prone position (PP) for invasively ventilated patients with COVID-19 is progressively increasing from the first pandemic wave in everyday clinical practice. Among the suggested treatments for the management of ARDS patients, PP was recommended in the Surviving Sepsis Campaign COVID-19 guidelines as an adjuvant therapy for improving ventilation. In patients with severe classical ARDS, some authors reported that early application of prolonged PP sessions significantly decreases 28-day and 90-day mortality. Methods and analysis Since January 2021, the COVID19 Veneto ICU Network research group has developed and implemented nationally and internationally the "PROVENT-C19 Registry", endorsed by the Italian Society of Anesthesia Analgesia Resuscitation and Intensive Care. . .'(SIAARTI). The PROVENT-C19 Registry wishes to describe 1. The real clinical practice on the use of PP in COVID-19 patients during the pandemic at a National and International level; and 2. Potential baseline and clinical characteristics that identify subpopulations of invasively ventilated patients with COVID-19 that may improve daily from PP therapy. This web-based registry will provide relevant information on how the database research tools may improve our daily clinical practice. Conclusions This multicenter, prospective registry is the first to identify and characterize the role of PP on clinical outcome in COVID-19 patients. In recent years, data emerging from large registries have been increasingly used to provide real-world evidence on the effectiveness, quality, and safety of a clinical intervention. Indeed observation-based registries could be effective tools aimed at identifying specific clusters of patients within a large study population with widely heterogeneous clinical characteristics.
