Evaluating overland flow sediment transport capacity
1998
An equation for evaluating the sediment transport capacity of overland flow is a necessary part of a physically based soil erosion model describing sediment detachment and transport as distributed processes. At first, for the hydraulic conditions of small-scale and large-scale roughness, the sediment transport capacity relationship used in the WEPP model is calibrated by Yalin and Govers' equation. The analysis shows that the transport coefficient Kt depends on the Shields parameter, Y, according to a semi-logarithmic (Yalin) or a linear (Govers) equation. The reliability of the semi-logarithmic equation is verified by Smart's, and Aziz and Scott's experimental data. Then the Low's formula,…

In this paper the results on three simple flumes for flow measurements are discussed.
New Stage–Discharge Relationship for Triangular Broad-Crested Weirs
2022
Simple hydraulic structures, such as weirs, allow measuring flow discharge by using the upstream flow depth and a stage–discharge relationship. In this relationship, a discharge coefficient is introduced to correct all the effects neglected in the derivation (viscosity, surface tension, velocity head in the approach channel, flow turbulence, non-uniform velocity profile, and streamline curvature due to weir contraction). In this paper, the dimensional analysis and the incomplete self-similarity theory are used to investigate the outflow process of triangular broad-crested weirs, characterized by different values of the ratio between crest height p and channel width B, and to theoretic…
Comment on "Measuring the flow resistance of submerged grass"
2004
In this short note, the experimental data of Wilson and Horritt (2002.Hydrological Processes16: 2589–2598), jointlywith the measurements by Kouwenet al. (1969.Journal of Irrigation and Drainage Division, ASCE95: 329–342)and by Raffaelliet al. (2002 InProceedings XXVIII Convegno di Idraulica e Costruzioni Idrauliche, Cosenza, Italy;223–230), arefirstly used to test Kouwen’s approach. All experimental data are then used to calibrate aflow resistanceequation that was theoretically deduced by dimensional analysis and self-similarity theory

Estudio comparativo de la combinación de diferentes modos de administración de anestésicos locales en la analgesia del parto
2020
La analgesia epidural es una de las técnicas más demandadas y por ello dicha analgesia ha ido evolucionando en los últimos años. Recientemente se ha desarrollado el modo PIEB (Programmed Intermittent Epidural Boluses) que puede reducir el consumo de anestésico local y así minimizar consecuencias indeseables tales como la cardio o la neurotoxicidad. En el año 2012 la compañía Smiths Medical lanzó al mercado un sistema de infusión ambulatoria CADD®-Solis versión software 3.0 de la generación de bombas de infusión CADD® que permite combinar varios modos de administración del anestésico local en el espacio epidural, hasta ahora no utilizados juntos ya que no existía en el mercado una bomba con …
