Download or read book Mattie C s Boy written by Don Keith and published by NewSouth Books. This book was released on 2013-06-01 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shelley Stewart was five years old when he and his brothers watched in horror as their father murdered their mother with an ax. Homeless at the age of six, Stewart found what shelter he could, suffering physical and sexual abuse and racism. Despite heartbreaking setbacks and the racial strife that gripped the South in the 1950s and 1960s, Stewart graduated high school and entered the broadcasting profession. There he became a hugely popular radio personality, rubbing shoulders with the top recording artists of the day and becoming one of the nation’s first black radio station owners. He helped Dr. Martin Luther King mount the historic Children’s March through the streets of Birmingham, Alabama. Later Stewart would use his powerful communication skills to help convict one of the men who bombed the city’s Sixteenth Street Baptist Church. Then this often-honored man turned his business skills to the creation of a foundation named after his mother; the Mattie C. Stewart Foundation works to convince high school students to stay in school and graduate, a topic Stewart speaks on in his many engagements around the country. Stewart, with author Don Keith, tells his story in his memoir Mattie C.'s Boy.

Download or read book Wave Riding into Therapy written by Matthew Stephen Kraus and published by Xlibris Corporation. This book was released on 2019-11-23 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: A group of surfers ride waves at their local beaches and find cosmological explanations in elements of their sport. Over about twenty years as the wave riding is cosmologically described, they show surfing instincts and practices. Doctor Charlton, is a member of their coterie, and he comments along the way. He and another doctor, Doctor Luther, who also rides waves, therapeutically treat members of the group of surfers. But it is mostly Stoney, who is the more serious case. Their wave riding continues. This book might be considered one of those one reads and puts on the shelf. Some parts are cosmological.
Download or read book Shore Wave Modulation Due to Infragravity Waves in the Nearshore Zone with Applications written by Saad M. M. Abdelrahman and published by . This book was released on 1986 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The omni-present low frequency wave motion (30-300 sec) contains a substantial fraction of the total wave energy inside the surf zone. A more complete description of nearshore wave processes considers incident short period waves superposed on, and interacting with, long standing waves. The wind waves are modulated in amplitude, wavenumber and direction due to relatively slowly varying depth changes caused by the long waves. The energy in the wind wave band is enhanced by side band growth at the sum and difference frequencies of short and long waves (order 15% at the shoreline). The modulation is identified in the analysis of field data as a positive correlation between the long waves and the wind wave envelope near the shoreline. Considering oblique incident waves, a steady longshore current showing a non-vanishing current at the shoreline is found as a result of the non-linear interaction between monochromatic incident and infragravity waves. An analytical solution describing the unsteadiness of the longshore current is developed. Keywords include: Infragravity, Longshore Current, Sediment transport, and Surf zone dynamics. (Theses).
Download or read book Breaking and Dissipation of Ocean Surface Waves written by Alexander Babanin and published by Cambridge University Press. This book was released on 2011-05-19 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wave breaking represents one of the most interesting and challenging problems for fluid mechanics and physical oceanography. Over the last fifteen years our understanding has undergone a dramatic leap forward, and wave breaking has emerged as a process whose physics is clarified and quantified. Ocean wave breaking plays the primary role in the air-sea exchange of momentum, mass and heat, and it is of significant importance for ocean remote sensing, coastal and ocean engineering, navigation and other practical applications. This book outlines the state of the art in our understanding of wave breaking and presents the main outstanding problems. It is a valuable resource for anyone interested in this topic, including researchers, modellers, forecasters, engineers and graduate students in physical oceanography, meteorology and ocean engineering.

Download or read book Breaking Waves written by Michael L. Banner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wave breaking is a commonly occurring phenomena associated with wave motion in fluids, often inducing significant effects which are of fundamental and technological importance, A familiar illustration is provided with white-capping and microbreaking of the wind-driven ocean sUrface waves, which is believed to play an important part in the transfers of momentum, mass and heat across the air-sea interface, as well as in the production of underwater ambient noise and augmented microwave backscatter. The enhanced hydrodynamic forces associated with the breaking of the more energetic ocean wave components constitute a significant challenge in ocean engineering, coastal engineering and naval architecture. Other less conspicuous but equally important manifestations are the breaking of internal waves and the fila mentation of vorticity interfaces. Despite recent theoretical and observational progress towards a more complete understanding of wave breaking, mathematical descriptions of its onset and consequences are presently lacking. The aim of this Symposium was to bring together theoretical and observational expertise, with the goal of determining the current state of knowledge of wave breaking and providing a stimulus to future research. The Symposium focused on water waves of all scales from capillary waves to ocean swell, but also considered internal waves and the filamentation of vorticity interfaces. Specific topics included were: Fundamental theoretical studies; wave instabilities; routes to breaking. Models of wave breaking. Field observations, including statistical information. Laboratory studies. Shoaling waves, breaking waves on currents, breaking induced by the motion of a ship.

Download or read book On the Short Waves 1923 1945 written by Jerome S. Berg and published by McFarland. This book was released on 2007-03-28 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: As radio developed in the early 1920s, the focus for most people was the AM band and stations such as KDKA, the first broadcast station. There was, however, another broadcast method that was popular among many early enthusiasts--shortwave radio. As is true today, the transmission of news and entertainment programs over shortwave frequencies permitted reception over great distances. For many in America and beyond, shortwave was an exciting aspect of the new medium. Some still tune the shortwave bands to enjoy the programming. Others pursue broadcasts for the thrill of the hunt. This book fully covers shortwave broadcasting from its beginning through World War II. A technical history examining the medium's development and use tells the story of a listener community that spanned the globe. Included are overviews of the primary shortwave stations operating worldwide in the 1930s, along with clubs and competitions, publications and prizes. A rich collection of illustrations includes many QSLs, the cards that stations sent to acknowledge receipt of their transmissions and that are much prized by long-distance collectors.
