Flow rate measurement in gravity irrigation systems using sluice gates

Agrociencia Uruguay
Gates are used to divert water to rice production plots in eastern Uruguay. In this study, the operating curves of rectangular gates installed at the entrance of circular section pipes are determined for submerged discharge conditions, which can be also ...

Boosting ensembles for estimation of discharge coefficient and through flow discharge in broad-crested gabion weirs

Applied Water Science, 2022
Gabion weirs are environment-friendly structures widely used for irrigation and drainage network purposes. These structures' hydraulic performance is fundamentally different from solid weirs' due to their porosity and the existence of a through-flow ...

Discharge Coefficient of Contracted Rectangular Sharp-Crested Weirs, an Experimental Study

Journal of Engineering, 2023
An experimental study is made here to investigate the discharge coefficient for contracted rectangular Sharp crested weirs. Three Models are used, each with different weir width to flume width ratios (0.333, 0.5, and 0.666).

Coefficient of Discharge of Freeing Port

Journal of Zosen Kiokai, 1960
It is needful in design of the freeing ports to know discharge coefficients of them. Results of experimental studies now conducted are as follows.1. The fundamental coefficients for full-sized ports (Fig. 1), standing and upright, are shown in Figs. 2-5.2.

Epigenetic silencing of the liver‐specific lncRNA LUNAR promotes liver cancer progression via NOTCH activation

Molecular Oncology, EarlyView.
LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...
