This book focuses on the computational analysis of nonlinear vibrations of structural members (beams, plates, panels, shells), where the studied dynamical problems can be reduced to the consideration of one spatial variable and time. The reduction is carried out based on a formal mathematical approach aimed at reducing the problems with infinite dimension to finite ones. The process also includes a transition from governing nonlinear partial differential equations to a set of finite number of ordinary differential equations.Beginning with an overview of the recent results devoted to the analysis and control of nonlinear dynamics of structural members, placing emphasis on stability, buckling, bifurcation and deterministic chaos, simple chaotic systems are briefly discussed. Next, bifurcation and chaotic dynamics of the Euler-Bernoulli and Timoshenko beams including the geometric and physical nonlinearity as well as the elastic-plastic deformations are illustrated. Despite the employed classical numerical analysis of nonlinear phenomena, the various wavelet transforms and the four Lyapunov exponents are used to detect, monitor and possibly control chaos, hyper-chaos, hyper-hyper-chaos and deep chaos exhibited by rectangular plate-strips and cylindrical panels.The book is intended for post-graduate and doctoral students, applied mathematicians, physicists, teachers and lecturers of universities and companies dealing with a nonlinear dynamical system, as well as theoretically inclined engineers of mechanical and civil engineering.

This paper presents an overview of water-related governance structures and institutions in the Limpopo Basin. The Basin is of critical socio-economic importance to the 14 million peopledistributed across the four riparian states of Botswana, Mozambique, South Africa and Zimbabwe.Urban centers, mostly in Botswana and South Africa, are major water users supplying industries, power stations and municipalities. Water is also used in rural areas for domestic, livestock watering and irrigation purposes. While irrigated agricultural activities are largely concentrated in South Africa and Zimbabwe, the majority of rural populations engage in rain-fed agriculture, which does not guarantee secure livelihoods. This is due, in large part, to the region’s semi-arid climate where only two out of every five agricultural seasons produce reasonable crop yields. These climatic conditions emphasize the need for effective management of transboundary water resources and effective governance structures, delivery and control mechanisms. Appropriate institutional frameworks and governance structures have a pivotal role in defining the socio-economic situation of the people in the Basin.

Only Anton Harber, a pioneer of independent journalism in south Africa and one of the keenest observers of the media around, could have written the thriller that is this book.' – Jacob Dlamini Veteran journalist Anton Harber brings all his investigative skills to bear on his very own profession, the media. For two years he conducted dozens of interviews with politicians, journalists, policemen, state security agents and 'deep throats', before piecing together two remarkable tales. The first is a chilling story of police death squads, rogue units and renditions, and how South Africa's biggest newspaper was duped into doing the dirty work of corrupt politicians. The second starts with a broken and discarded hard drive and evolves, with many near misses, into the exposure of the depths of the Guptas' influence over the ruling party. Harber's two tales reveal the lows and highs of journalism during an era of state capture. His book is both a disquieting exposé of how easily the media can be duped by a conniving cabal for its own selfish ends, and a celebration of brilliant investigative reporting by brave and ethical journalists.

The conservation of the rhinos in southern Africa is described in this account of these fascinating animals, the reasons behind their historical decline, the myths that surround them, and the resurrection of the rhinoceros horn trade. Few animals face as violent, as well organized, and as determined an enemy as the world's rhinos. But across the African continent, they are being slaughtered on a daily basis, and approximately 5,000 black rhinos and 21,000 white rhinos are all that prevent their extinction. This real account of the rhino wars is a harrowing story, underscoring the enormous challenges that lie ahead for conservation in a world where rhino horns sold by the gram raise double the price of gold and are more expensive than cocaine in the end-user Asian markets. Arguing that protecting Africa's rhinos is of utmost importance, it questions the management of natural heritage and implores readers to recognize their role as rhino keepers of the future.
