Thermal Structure of the Topside Ionosphere Observed by INJUN 5 During an Intense Magnetic Storm


Book Description

Electron densities and temperatures as well as omnidirectional fluxes of hyperthermal positive ions (E > 28 eV) were measured by means of spherical Langmuir probes aboard INJUN 5 at altitudes > 2000 km during a major geomagnetic storm. The electron density in the mid-latitude trough decreased and the temperatures increased during the early phases of the storm. As the storm progressed the trough's position moves equatorward with plasma depletions being observed to an invariant latitude of 40 deg during the early recovery phase. The latitude of the transition between heavy and light ion dominance also moved equatorward, but recovered at a rate slower than that of the electron trough's position. Hyperthermal ions detected in the vicinity of the trough were ring current particles reaching to the satellite's altitude. The minimum thermal electron densities in the trough were found to be within 1 deg of latitude of the maximum ring current flux. Maximum electron temperatures were measured several degrees equatorward of this position. INJUN 5 electron temperatures are compared with those measured by Alouette 2 over the reported positions of SAR arcs. The observations are also used to further evaluate a method developed for calculating the position of the ring current using ground magnetic fluctuations.




Design Aids for Offshore Topside Platforms Under Special Loads


Book Description

Offshore platforms face many risks, including a hostile ocean environment, extreme temperatures, overpressure loads, fire risks, and hydrocarbon explosions, all of which pose unique challenges in designing their topside platforms. The topside design also involves the selection of appropriate materials to reduce fire risk without compromising the functional requirements. These platforms serve valuable, utility, production, and processing purposes, and can also provide living quarters for personnel. Concepts such as basic design, special design, materials selection, and risk hazards are explained in the authors' straightforward classroom style, and are based on their rich experience in both academia and industry. Features • Includes practical examples which are solved using international codes to offer a better understanding of the subjects presented • Addresses safety and risk of offshore platforms, and considers numerous topside accident scenarios • Discusses the structural and mechanical properties of various materials, such as steel and newer functionally graded materials (FGMs) Design Aids for Offshore Topside Platforms Under Special Loads serves as a design manual for multi-disciplinary engineering graduates and practicing professionals working in civil, mechanical, offshore, naval, and petroleum engineering fields. In addition, the book will serve as reference manual for practicing design engineers and risk assessors.







Papa Topside


Book Description

A pioneer in the field of deep-sea diving, George F. Bond helped develop the theory of saturation diving and the techniques and dive tables used by divers around the world. In this edited journal Bond offers a lively account of his work with the U.S. Navy’s first manned undersea habitats, the Sealab experiments of the 1960s. Dubbed “Papa Topside” by the media that followed his work with Navy aquanauts, Bond gives a colorful eyewitness account of what today are considered benchmarks in the history of diving. This is a candid, personal record of Sealabs I, II, and III, and the FISSH experiment, the finale of Bond’s career. The picture that emerges is one of a brilliant, larger-than-life figure who, though often difficult to get along with, earned the respect and affection of his peers. The book draws on the editor’s interviews with Bond’s fellow researchers and divers, editor Helen Siiteri as well as Bond’s daily logs and correspondence. Always frank and to the point, he describes his frustrations with the Navy brass, his friendly competition with Jacques Cousteau, and his spirited relationship with aquanaut/astronaut Scott Carpenter. As the only full-length book written about U.S. aquanauts and their undersea exploits, it is an important historical document. It is also an entertaining read.
