Cross-sectional flow and bed shear stress: application of the depth-averaged momentum equation in a meandering laboratory flume

Dramme, didrammi e tetradrammi di Panormos e a legenda ṣyṣ nel V secolo a.C.: aggiornamenti e riflessioni intorno alle sequenze dei conî

2019

The main objective of this essay is to comment upon the modes of production and the datings of the 5th century BC non-fractional silver coinage bearing the Greek legend ΠΑΝΟΡΜΟΣ (and variants) and the Punic legend ṣyṣ. The reconstruction of the die sequences published by G. Kenneth Jenkins in 1971 and its recent updates will be discussed in detail. As far as the identification of the issuing authority and of the minting place of the coins with legend ṣyṣ is concerned, for a long time to the center of the scientific research interests, only the inferences made from an analysis of the die sequence have been taken into consideration.

Bank Erosion and Secondary Circulation in a Meandering Laboratory Flume

2014

Abstract This paper reports peculiar results of experimental investigation on the secondary circulation motion of flow along a meander wave. Experiments were conducted in a large amplitude meandering laboratory channel for two values of the width-to-depth ratio. Here attention is focalized on how secondary motion affects the bank shear stress distribution, influencing the stability of the outer bank. The analysis essentially highlights that, especially for small width-to-depth ratio, as the channel curvature increases, besides the classical central-region secondary circulation cell a counter-rotating circulation cell forms in the outer-bank region. Such counter-rotating circulation cell all…

A new approach to model the effect of climate change on the building sector: A climate models data fusion

2020

Several climate models have been developed and used to forecast the effects of the climate changes, however the variability of results due to different models lead to a significant uncertainty on the estimation of the building energy use for the next century. In this context, the paper analyses this uncertainty and combines different climate models in order to improve the robustness of energy consumption predictions. The data of the climate models were then used to generate hourly weather files for the future period 2020-2099 and energy simulations for a case study located in Palermo (Italy) were performed. Results show a wide variability among all models (either alone or combined with our …

Arterial Hypertension and the Hidden Disease of the Eye: Diagnostic Tools and Therapeutic Strategies.

2022

Hypertension is a major cardiovascular risk factor that is responsible for a heavy burden of morbidity and mortality worldwide. A critical aspect of cardiovascular risk estimation in hypertensive patients depends on the assessment of hypertension-mediated organ damage (HMOD), namely the generalized structural and functional changes in major organs induced by persistently elevated blood pressure values. The vasculature of the eye shares several common structural, functional, and embryological features with that of the heart, brain, and kidney. Since retinal microcirculation offers the unique advantage of being directly accessible to non-invasive and relatively simple investigation tools, the…

The renal resistive index: is it a misnomer?

2015

Progress in digital ultrasound technology and diffusion of Doppler ultrasound evaluation of the kidney enable a widespread non-invasive evaluation of renal haemodynamics. Initially most attention has been paid to the study of extraparenchymal renal arteries, mainly to detect renovascular disease. However, this approach has low reproducibility and accuracy. Therefore, interest has gradually moved towards the duplex evaluation of intrarenal anatomy, where the best and most reliable signals are obtained from the large segmental or interlobar arteries that run directly towards the transducer. Among the sonographic parameters used in the last decade, great emphasis has been placed on the intrare…
