Hydraulic characteristics of flow over weirs with circular openings
Ain Shams Engineering Journal, 2017 AbstractWeirs may be used to control the discharge, decrease the water slope in canals and to distribute water between canals for irrigation, etc. The objective of this research was to investigate the influence of using one opening or more in weirs on discharge coefficient (Cd), the hydraulic jump characteristics and velocity distribution downstream of

Stage–discharge relationship for a pipe overflow structure in both free and submerged flow
Engineering Applications of Computational Fluid Mechanics, 2016 Many facilities for urban drainage systems are equipped with a pipe overflow structure that can often be treated as a circular broad-crested weir. Thus it is possible to evaluate the overflow discharge through this device by measuring the water levels in

Overflow Characteristics of Circular Weirs : Effect of Inflow Conditions [PDF]
, 1998 The most common types of weirs are the broad-crested weir, the sharp-crested weir, the circular-crested weir and nowadays the ogee crest weir. Advantages of the cylindrical weir shape include the stable overflow pattern, the ease to pass floating debris,

Constructing Difference: Maternal Boundary‐Work in Science‐Based and Natural Mom Groups on Facebook
Symbolic Interaction, EarlyView.Boundary‐work describes the activities of social groups as they seek to differentiate themselves from others to establish credibility, authority, or to protect their interests. While a growing body of literature explores occupational boundary‐work in health care, limited research has focused on how lay actors practice boundary‐work online.

Digging into dirt: Rewilding with threatened mammals shapes soil‐emerging insect assemblages
Journal of Animal Ecology, EarlyView.By comparing insect communities across treatments at two time points, we show that reintroduced digging mammals shape soil‐emerging insect assemblages. This provides empirical evidence that restoring ecosystem engineers may drive broader community‐level change in semi‐arid ecosystems. Abstract Digging mammals function as ecosystem engineers by altering

Secularism, Gender and Masculinity in Nineteenth‐Century Cremation in Europe and the USA
Gender &History, EarlyView.ABSTRACT This essay explores, from transnational perspectives, the early history of modern cremation, which developed in the long nineteenth century with secularist connotations.
