Tiny bubbles challenge giant turbines: Three Gorges puzzle.
Since the birth of the first prototype of the modern reaction turbine, cavitation as conjectured by Euler in 1754 always presents as a challenge. Following his theory, the evolution of modern reaction (Francis and Kaplan) turbines has been completed by adding the final piece of the element 'draft-tube' that enables turbines to explore water energy at efficiencies of almost 100%. However, during...
متن کاملThree Gorges project: chance and challenge.
THE THREE GORGES DAM (TGD) ACROSS THE Yangtze River is the world’s largest hydroelectric dam (1). Construction of the TGD will form many different sizes of islands, providing a golden opportunity for exploring the ways in which island ecosystems are regulated (1). However, the construction will also pose great challenges to the ecosystem of the Three Gorges Reservoir Area (TGRA). It will affect...
متن کاملTiny ImageNet Visual Recognition Challenge
In this work, we investigate the effect of convolutional network depth, receptive field size, dropout layers, rectified activation unit type and dataset noise on its accuracy in Tiny-ImageNet Challenge settings. In order to make a thorough evaluation of the cause of the peformance improvement, we start with a basic 5 layer model with 5×5 convolutional receptive fields. We keep increasing networ...

Introduction Nosocomial pneumonia is a major source of morbidity and mortality after severe burns. Burned patients suffer trace element deficiencies and depressed antioxidant and immune defences. This study aimed at determining the effect of trace element supplementation on nosocomial or intensive care unit (ICU)-acquired pneumonia. Methods Two consecutive, randomised, double-blinded, supplemen...
متن کاملThree-Gorges Dam: risk to ancient fish.
THE HUGE THREE-GORGES DAM (TGD) OF THE Yangtze River is going to demonstrate the mighty power of humanity to change and fragment an area of about 58,000 km2 with the formation of a huge reservoir of 1080 km2. It is expected to exert disastrous influences on many terrestrial plants and animals, as discussed by J. Wu et al. in their Policy Forum “Three-Gorges Dam— experiment in habitat fragmentat...
