One week of levofloxacin plus dexamethasone eye drops for cataract surgery: an innovative and rational therapeutic strategy
2020
Background: Cataract surgery is the most common operation performed worldwide. A fixed topical corticosteroid-antibiotic combination is usually prescribed in clinical practice for 2 or more weeks to treat post surgical inflammation and prevent infection. However, this protracted schedule may increase the incidence of corticosteroid-related adverse events and notably promote antibiotic resistance. Methods: This International, multicentre, randomized, blinded-assessor, parallel-group clinical study evaluated the non-inferiority of 1-week levofloxacin/dexamethasone eye drops, followed by 1-week dexamethasone alone, vs. 2-week gold-standard tobramycin/dexamethasone (one drop QID for all schedul…
The impact of COVID-19 on access to dental care for people with disabilities:a global survey during the COVID-19 first wave lockdown
2021
Background It is unclear what immediate impact the COVID-19 pandemic has had on delivery of oral healthcare to people with disabilities worldwide. Aim: To report the international impact of COVID-19 lockdown on oral healthcare provision for people with disabilities before, during and after the first lockdown (March to July 2020). Material and Methods Cross-sectional online self-administered survey of dentists who treat people with disabilities completed 10th to 31st of July 2020. Responses allowed comparison from before, during and immediately after the first wave lockdowns of the COVID-19 pandemic. Data were analysed using McNemar’s test to compare reported practice before to during lockdo…
Different Measurement Setup Configurations for Space Charge test in Mini Cable Specimens with the PEA Method
2019
Under DC stress, the space charge accumulation is believed one of the most responsible of dielectrics ageing. For this reason, due to the increase of the HVDC transmission, a recommendation has been proposed. The latter want to introduce the space charge measure, with the PEA method, in cable specimens during the prequalification or type tests. Considering the several issues related to this kind of measures the aim of the proposed work is find a measurement setup for mini cable specimens which is able to provide a clear and clean space charge profile. Therefore, different tests have been made in this work. In particular, the length of the cable specimen, the width of the pulse electrodes, a…
A new approach to calibrate the thermal conditions in space charge measurements on HVDC mini-cables
2019
The PEA method is currently widespread used for space charge measurements in mini-cables in order to qualify the behavior of semicon-dielectric-semicon compound under electric and thermal stress. The main goal of this research is to quantitatively evaluate the relationship between the thermal boundary conditions applied to cables or mini-cables and the maximum local electric field due to the accumulated space charge. Hitherto, several research groups have obtained thermal gradients over the dielectric's radius heating the conductor by Joule effect due to an induced current. In this paper, a numerical approach is offered to calibrate the heat exchange boundary conditions to apply to a sample…
Synergies in Design and Health. The role of architects and urban health planners in tackling key contemporary public health challenges
2020
Background and aim: Important public health improvements have been achieved over the past decades, but new challenges are emerging and progress cannot be taken for granted. Urban settlements host most of the global population, but they are also sources of several threats. The aim of the paper is to investigate the role of architects and planners in contributing to overcome these critical health challenges and propose strategic actions for collaboration with the public health workforce. Methods: Taking global trends and public health challenges as starting point, a scoping literature review has been conducted to illustrate the possible synergies that architecture and public health workforce …
L'AFFAIRE EXPEDIA DECISO DALLA CASSAZIONE FRANCESE: UNA OCCASIONE DI RIFLESSIONE SU GIURISDIZIONE E DIRITTO APPLICABILE NELLE CONTROVERSIE CON LE PIA…
2021
The essay analyzes the French case law related to the matter of wheater the clauses of jurisdiction and applicable law in a contract between an online platform and its affiliated economic operators is binding and enforceable also against the Ministre de l’économie et des finances in the context of an action based on cross-border practices restricting competition, such as those repre- sented by the imposition by Expedia of the Most Favoured Nation’s clause to its affiliated hotels.
Pulsed Electro-Acoustic space charge apparatus – qualifying, testing and monitoring of insulation for HVDC cables and accessories

Party autonomy regarding jurisdiction under the property regimes regulations
2021
The main accomplishment of the Property Regimes Regulations lies in their bringing more coherence into the cross-border family law adjudication. In the field of international jurisdiction, they strive to align the competence in couples? patrimony disputes to that in succession and in separation proceedings, or else to align the competence of the courts to the applicable law. These tendencies are clearly visible in the Regulations? provisions on choice of court agreements. Namely, the Regulations allow for such agreements, but severely limit parties? choice and the possible effects of these clauses. When succession or separation proceedings are pending, it is often only possible to institute…
Partial Discharges in HVDC Cables - The Effect of the Temperature Gradient During Load Transients
2021
The paper investigates the role of the space charge accumulation phenomena in the inception of Partial Discharges (PD) in a defect within the bulk of the dielectrics of a High Voltage Direct Current (HVDC) cable. It is widespread accepted that the number of PD occurring in an HVDC cable during its lifetime is largely less than that under AC voltage stress. This is essentially due to higher values of the voltage between the conductor and the screen needed to trigger PD under a steady DC voltage than the same value under AC stress. Nevertheless, due to the dependency of the electrical conductivity of the insulation on the electric field and temperature, PD in HVDC cables is strongly influence…
