The aim of this study is to present a peculiar experimental setup, designed to investigate the interaction between solitary waves and rigid emergent vegetation. Flow rate changes due to the opening and closing of a software-controlled electro-valve generate a solitary wave. The complexity of the problem required the combined use of different measurement systems of water level and velocity. Preliminary results of the experimental investigation, which allow us to point out the effect of the vegetation on the propagation of a solitary wave and the effectiveness of the measuring system, are also presented. In particular, water level and velocity field changes due to the interaction of the wave with rigid vegetation are investigated in detail.

Background: Patients with solitary functioning kidney appear to be exposed to an increased cardiovascular risk. This study aimed to evaluate the impact of peripheral and central blood pressure on subclinical cardiovascular organ damage in a sample of children and adolescents with solitary functioning kidney.
Methods: Carotid ultrasonography was performed to measure the carotid intima-media thickness (cIMT) and the carotid distensibility coefficient.

The formation of a S-shaped filament was investigated to determine if and how magnetoacoustic waves in the solar corona can trigger filament excitation. The study investigated how magnetoacoustic waves interact with two magnetic null points in the solar corona. Since the solar corona has a complex magnetic field structure, it is expected that magnetic structures are predominantly responsible for the occurrence of coronal events.

Introduction: Horseshoe kidney is often associated with ureteropelvic junction obstruction and nephrolithiasis. Retrograde intrarenal surgery (RIRS) is becoming one of the main treatment options for large stones in such patients.
Aim: To study the results of RIRS in patients with horseshoe kidney.

Solitary wave solutions to the nonlinear evolution equations have recently attracted widespread interest in engineering and physical sciences. In this work, we investigate the fractional generalised nonlinear Pochhammer-Chree equation under the power-law of nonlinearity with order m. This equation is used to describe longitudinal deformation wave propagation in an elastic rod.
