Abstract Through the study of diameter control horizontal swirling efficiency shaft and tunnel cross-section aeration sill, a flood discharge with scale about 100 meters volume more than thousand is obtained. The energy dissipation type combined diversion tunnel. At time, can be controlled determined according to average velocity 15-20m/s; hole calculated empirical formula D=(Q 2 /g) 0.2 . In o...

High core recovery at Ocean Drilling Program (ODP) Leg 210, Site 1276, provided a high-resolution porosity-depth relationship and an equally impressive age-depth model based on first and last occurrences of microfossils. Site 1276 was drilled over transitional crust in the Newfoundland nonvolcanic margin, offshore Canada, between known continental crust on the west and apparent oceanic crust on...

Sill,?Whilst perusing the article of Captain GreenArmytage on "The use and abuse of Pessaries" in the February number of the Indian Medical Gazette, my attention was drawn to his anatomical description of the Floor of the Pelvis. The pelvic floor of course consists only of a muscular sheet, the levator ani and coccygeus muscles?you have structures above it and structures below it, and some of t...

This study investigated the relationship between language learning aptitude (LLA) and the use of language learning strategies (LLSs) among a cohort of Iranian EFL students at Urmia University, Iran. The adapted versions of the Modern Language Aptitude Test (MLAT; Carrol & Sapon, 1983) and Oxford’s (1990) Strategy Inventory for Language Learning (SILL) were distributed among the participants (i....

Lunar floor-fractured craters (FFCs) represent the surface manifestation of a class of shallow crustal intrusions in which magma-filled cracks (dikes) rising to the surface from great depth encounter contrasts in host rock lithology (breccia lens, rigid solidified melt sheet) and intrude laterally to form a sill, laccolith or bysmalith, thereby uplifting and deforming the crater floor. Recent d...

The three-dimensional problem of wave trapping above a submerged round sill was first analysed by Longuet-Higgins on the basis of a linear shallow-water theory. The large responses predicted by the theory were, however, not well borne out by the experiments of Barnard, Pritchard & Provis, and this has motivated a more detailed study of the problem. A full linear theory for both inviscid and wea...

The present research was conducted to investigate the effect of sill geometry and width on discharge coefficient hydraulic jump characteristics. For this purpose, sills with semi-cylindrical, cylindrical, pyramidal, rectangular cube geometries widths 0.075, 0.10, 0.15, 0.2 m were installed under a sluice gate. Results showed that increasing increased gate compared no-sill mode. results placing ...
