Numerical and analysis effects of rectangular prism rough beds on hydraulic jumps in open channels
AIP AdvancesHydraulic jumps are characterized by intense turbulence and substantial energy dissipation in open channel flows or stilling basins. This study utilizes the Flow-3D hydraulic computational model, integrating the renormalization group k-ε turbulence model

Uplift force and momenta on a slab subjected to hydraulic jump
Dyna, 2016 As part of the search for safe and economic design criterion to line slabs of stilling basins, the present study is one of the first to calculate the center of pressure, uplift forces, and momenta from a spatiotemporal analysis of the pressures measured ...

Impact pressures of turbulent high-velocity jets plunging in pools with flat bottom [PDF]
, 2018 Dynamic pressures created by the impact of high-velocity turbulent jets plunging in a water pool with flat bottom were investigated. Pressure fluctuations were sampled at 1kHz at the jet outlet and at the pool bottom using piezo-resistive pressure ...

The Anatomical Record, EarlyView.Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...

The Anatomical Record, EarlyView.Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

The Anatomical Record, EarlyView.Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Archaeological Prospection, EarlyView.ABSTRACT This study presents a strong framework for the detection and classification of Submerged Cultural Heritage Assets (SCHA) in shallow marine environments using the integration of multibeam echosounder and airborne LiDAR bathymetry with object‐based image analysis and fuzzy logic–based classification.

Archaeological Prospection, EarlyView.ABSTRACT Ancient Olympia was one of the most important sanctuaries and the venue for the Olympic Games in Greek and Roman times. Its remains are located in the Olympia Terrace (Peloponnese, Greece) at the present‐day confluence of the rivers Alpheios and Kladeos at the base of Mount Kronos.

A hybrid high efficiency single-basin solar still
International Journal of Energy Research, 1996 In this work, an attempt has been made to enhance the distillate output of a single-basin solar still by coupling it with a flat plate solar collector and by coating a thin layer of SnO 2 on one side of the transparent cover plate. The heat transfer fluid was circulated between the still and the collector through a heat exchanger and storage tank by ...
