The one-dimensional (1D) power law velocity distribution, commonly used for computing velocities in open channel flow, has been derived empirically. However, a multitude of problems, such as scour around bridge piers, cutoffs and diversions, pollutant dispersion, and so on, require the velocity distribution in two dimensions. This paper employs the Shannon entropy theory for deriving the power ...

Background The research that informs this study was conducted in Chapra village, Kushtia District, Bangladesh, located about 20 km east of the Indian border. Chapra is located within the Ganges Dependent Area (GDA) in Bangladesh which, in turn, is located within the Ganges–Brahmaputra Basin (GBB), one of the largest river basins in the world by area and second only to the Amazon in terms of the...

Radical cystectomy is the gold standard for muscle-invasive urothelial carcinoma of the bladder because this operation provides excellent local cancer control. Laparoscopic radical cystectomy with different urinary diversions has been reported since 1992 and proposed as an alternative to open radical cystectomy. However, the reconstruction part of the operation is time-consuming and challenging...

AIM To evaluate the relationship between vascular endothelial growth factor (VEGF), p53, and the H-ras oncogene and different clinicopathological parameters in Egyptian patients with Schistosoma-associated transitional cell carcinoma of the bladder. METHODS The study included 50 patients with transitional cell carcinoma for whom radical cystectomy and urinary diversions were carried out. VEGF...

We derive 1D steady equilibria for partially saturated downslope flow as a solution to the reposed vadose-zone problem. The equilibria are determined by two free parameters: a mean flow and a downstream saturation. Where there is no downstream saturation, a uniform outflow of constant saturation is obtained, but if an isolated zone of excess downstream saturation exists, the upstream flow speed...

The issue of overcrowding in Emergency Departments (EDs) has become a significant national problem.1-5 Several recent scientific studies have added documentation of the overcrowding problem.6-8 In addition, discussions with emergency physicians across the country and at national meetings indicate that this is a major problem.9-11 Many private, academic, and urban EDs in both large and small com...

Ten years ago, serious overcrowding in emergency departments became a national issue. Although temporary improvement of the problem occurred, the issue of ED overcrowding has now resurfaced and threatens to become worse. Overcrowding is caused by a complex web of interrelated issues described in this article. ED overcrowding has multiple effects, including placing the patient at risk for poor o...

Diversion of river water has diminished freshwater flow into many estuaries worldwide, yet the effects of these diversions on marine fisheries, many of which depend on estuaries, are largely unexplored. We document the impact of diverting Colorado River flow from the Gulf of California on the life history of a now-endangered marine fish (Totoaba macdonaldi, Sciaenidae). Growth increments in pre...

Popular opinion of digital games tends to classify them as toys, diversions and distractions, however this focus on games solely as sources of hedonic pleasure is theoretically, empirically, and phenomenologically myopic – it obscures the full range of affective, emotional, and cognitive experiences that one can have when playing digital games. In this vein, this study explores the phenomenal e...

There are large amounts of insight and social discovery potential in mining crowd-sourced comments left on popular news forums like Reddit.com, Tumblr.com, Facebook.com and Hacker News. Unfortunately, due the overwhelming amount of participation with its varying quality of commentary, extracting value out of such data isn't always obvious nor timely. By designing efficient, single-pass and adap...
