Archivio italiano di urologia, andrologia : organo ufficiale [di] Societa italiana di ecografia urologica e nefrologica, 1994
After a brief historical introduction, the Authors describe the methodology of the continuous wave basic and dynamic Doppler examination of the penile arteries as well as the main normal and pathologic patterns. Some special tensiometric tests are reported. Advantages and limits of the afore mentioned examinations are discussed.

Hydrodynamic and ecological effects of engineered logjams: Insights from field observations

Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
Drone imaging, LSPIV and electrofishing data quantified restoration effects of engineered logjam at the Emme River (Switzerland). Placement and discharge shaped flow: Side jams created longer wakes, centre jams stronger mixing; and lower discharge intensified gap velocities, whereas wake length remained stable.

Uterine artery Doppler flow velocimetry parameters for predicting gestational trophoblastic neoplasia after complete hydatidiform mole, a prospective cohort study

Clinics
OBJECTIVES: Doppler ultrasonography can be used to assess neoangiogenesis, a characteristic feature of postmolar gestational trophoblastic neoplasia. However, there is limited information on whether uterine artery Doppler flow velocimetry parameters can ...

Sinogram‐based flow estimation in computed tomography using a physics‐informed neural network: Impact of gantry rotation speed, X‐ray fluence and pulsed acquisition on accuracy

Medical Physics, Volume 53, Issue 6, June 2026.
Abstract Background Non‐invasive imaging‐based assessment of blood flow plays a critical role in evaluating heart function and structure. Computed Tomography (CT) is a widely‐used imaging modality that can robustly evaluate cardiovascular anatomy and function, but direct methods to estimate blood flow velocity from movies of contrast dynamics have not ...

Design and Statistical Optimization of PLA Organoclay‐Based Dispersions for Recyclable Packaging Paper

Polymer Engineering &Science, Volume 66, Issue 6, Page 4321-4333, June 2026.
Through experimental design, polylactic acid (PLA)—organoclay dispersions were optimized to produce biobased coatings that have a high barrier potential while maintaining repulpability, promoting sustainable packaging solutions. ABSTRACT Performance and recyclability of paper coatings depend on precise control of polymer, surfactant, filler ...
