This study examines the influence of the application of a rotating magnetic field in the electrodeposition of copper (Cu).During the electrodeposition, five constant magnets were rotated (500 and 800 rpm) towards the bottom of the sample.To investigate deposition rate, surface morphology, phase, structure, corrosion resistance, and hardness in depo
In the previous article [Y.-X.Wang and W.-T.Li, J.Differential Equations, 251 (2011) 1670-1695], the authors have shown that the set of positive stationary solutions of a cross-diffusive Lotka-Volterra cooperative system can form an unbounded fish-hook shaped branch $Gamma_p$.In the present paper, we will show some criteria for the stability of pos
Ecosystems are undergoing unprecedented persistent deterioration due to unsustainable cocktail tree for sale anthropogenic human activities, such as overfishing and deforestation, and the effects of such damage on ecological stability are uncertain.Despite recent advances in experimental and theoretical studies on regime shifts and tipping points,
Abstract The use of high strength aluminium alloys, such as 6XXX and 7XXX series, is continuously increasing for automotive applications in view of their good strength-to-weight ratio.Their formability at room temperature is limited and they are thus often formed at high temperatures to enable production of complex geometries.Critical challenges du
In Productivity Revisited, the World Bank turns its ongoing productivity research program to the issue of the apparent failure of productivity in 173rd airborne brigade patch developing countries to converge to the higher productivity in advanced economies.The World Bank asserts, but provides little evidence, that converge is not taking place The a
