Protective ventilation with high versus low positive end-expiratory pressure during one-lung ventilation for thoracic surgery (PROTHOR): study protoc…
2019
Background: Postoperative pulmonary complications (PPC) may result in longer duration of in-hospital stay and even mortality. Both thoracic surgery and intraoperative mechanical ventilation settings add considerably to the risk of PPC. It is unclear if one-lung ventilation (OLV) for thoracic surgery with a strategy of intraoperative high positive end-expiratory pressure (PEEP) and recruitment maneuvers (RM) reduces PPC, compared to low PEEP without RM. Methods: PROTHOR is an international, multicenter, randomized, controlled, assessor-blinded, two-arm trial initiated by investigators of the PROtective VEntilation NETwork. In total, 2378 patients will be randomly assigned to one of two diffe…
WRKY gene family drives dormancy release in onion bulbs
2022
Onion (Allium cepa L.) is an important bulb crop grown worldwide. Dormancy in bulbous plants is an important physiological state mainly regulated by a complex gene network that determines a stop of vegetative growth during unfavorable seasons. Limited knowledge on the molecular mechanisms that regulate dormancy in onion were available until now. Here, a comparison between uninfected and onion yellow dwarf virus (OYDV)-infected onion bulbs highlighted an altered dormancy in the virus-infected plants, causing several symptoms, such as leaf striping, growth reduction, early bulb sprouting and rooting, as well as a lower abscisic acid (ABA) level at the start of dormancy. Furthermore, by compar…
Fonti per la storia del Manicomio di Palermo alla Vignicella (1884-1902)
2020
Il testo ripercorre le tappe che hanno condotto alla realizzazione di una delle più vaste opere pubbliche di stampo sanitario realizzate a Palermo nel XIX secolo: l'Ospedale Psichiatrico alla Vignicella. Tramite l’individuazione e l’analisi delle principali fonti ottocentesche e dei primissimi del Novecento, pur confrontandosi con la più recente letteratura periegetica, si fissano alcuni punti fermi rispetto alla progettazione ed esecuzione dei lavori, oltre che, non di meno, in relazione alla concezione scientifica sulle quali erano state fondate. Le immagini d’epoca accompagnano il testo in senso illustrativo e documentario. The text traces the steps that led to the construction of one of…
Mediating effects of motor performance, cardiorespiratory fitness, physical activity, and sedentary behaviour on the associations of adiposity and ot…
2018
We investigated the associations of cardiometabolic risk factors with academic achievement and whether motor performance, cardiorespiratory fitness, physical activity, or sedentary behaviour mediated these associations. Altogether 175 children 6-8 years-of-age participated in the study. We assessed body fat percentage (BF%), waist circumference, insulin, glucose, triglycerides, HDL cholesterol, and systolic and diastolic blood pressure, leptin, alanine aminotransferase, and gamma-glutamyltransferase (GGT). Reading fluency, reading comprehension, and arithmetic skills were assessed using standardized tests. Speed/agility, balance, and manual dexterity test results were used to calculate moto…
Measurement of the soliton number in guiding media through continuum generation.
2020
No general approach is available yet to measure directly the ratio between chromatic dispersion and the nonlinear coefficient, and hence the soliton number for a given optical pulse, in an arbitrary guiding medium. Here we solve this problem using continuum generation. We experimentally demonstrate our method in polarization-maintaining and single-mode fibers with positive and negative chromatic dispersion. Our technique also offers new opportunities to determine the chromatic dispersion of guiding media over a broad spectral range while pumping at a fixed wavelength. (C) 2020 Optical Society of America
Even harmonic pulse train generation by cross-polarization-modulation seeded instability in optical fibers
2012
International audience; We show that, by properly adjusting the relative state of polarization of the pump and of a weak modulation, with a frequency such that at least one of its even harmonics falls within the band of modulation instability, one obtains a fully modulated wave at the second or higher even harmonic of the initial modulation. An application of this principle to the generation of a 80-GHz optical pulse train with high extinction ratio from a 40-GHz weakly modulated pump is experimentally demonstrated using a nonzero dispersion shifted fiber in the telecom C band.

Las formas cotidianas de la felicidad y sus mandatos: Pedagogías del pensamiento positivo, trabajo docente y subjetividad en el neoliberalismo contem…
2020
Positive thinking constitutes one of the great traditions that lead to the idea of the subject as an entrepreneur of himself and is perhaps one of the best that has successfully condensed cultural, political, social and pedagogical processes linked to reflection on well-being in this historical time. The teaching work is especially moved by the pregnancy of these perspectives that challenge the pedagogical field and the education workers as ?agents of change, or at least one more school available to give the discussion on well-being and happiness (yours and the students?) is celebrated and encouraged. In this article, I intend to understand what is being built as pedagogical discourses abou…
The Mediating Role of Individual Differences in the Interaction between Specific Socioprofessional Pressures and Job Satisfaction
2014
Abstract Previous research suggests that individual differences play an essential role in the complex process of organisational stress. The mediator role of specific individual differences and coping strategies, in the stressor – strain (effect) relationship is investigated in the present research. One sample of romanian employees (N=311) from an administrative-public service organisation participated in the study. Using the Pressure Managment Indicator (PMI, Williams & Cooper, 1998 ; PMI-RO, Brate, 2004, 2008 ), findings revealed significant mediating interactions between specific socioprofessional pressures and job satisfaction. The results have practical implications for the future resea…
Fostering learning opportunities through employee participation amid organizational change
2014
Health care organizations are facing rapid changes, frequently involving modification of existing procedures. The case study reported here examined change processes and learning in a health care organization. The organizational change in question occurred in the emergency clinic of a Finnish central hospital where a new action model for shift-specific nursing supervision was being introduced. The aim of this study was to investigate some of the employee participation and learning opportunities amid this organizational change. The data collection was ethnographically informed, and the data consisted of audio-recorded and observed meetings, observations of the new action model, and field inte…
