Thermoforming: A Plastics Processing Guide, Second Edition
by Geza GruenwaldFROM THE FOREWORDDr. Gruenwald has indicated the desirable properties of polymerics for differing applications; thus, his text is especially useful for polymer chemists who must ""tailor"" plastic materials for specific groups of applications. Engineers in extruding and calendering film and sheet will benefit from the intimate relationships elucidated between processing parameters imposed upon stocks employed in thermoforming and the products thereof. Mold designers are provided with a complete guide that will enable them to avoid the less obvious pitfalls and wasted effort so often experienced in the evolution of molds for (especially) complex parts.. Quite likely, Dr. Gruenwald's suggestions willl lead to considerable benefits to those who read and practice by this remarkable exposition of thermoforming technology. Robert K. Jordan Director-Metalliding Institute, Director-Engineering Research Institute, Scientist in Residence, Gannon University

Thermophysical Properties of Heavy Petroleum Fluids (Petroleum Engineering)
by Bernardo Carreón-Calderón Verónica Uribe-Vargas Juan Pablo AguayoThis book addresses conventional and new predictive methodologies for estimating thermophysical properties of heavy petroleum fluids. For the unidentifiable fractions forming the fluids, chemical structures are calculated so that property estimation methods for mixtures of identifiable components are now available for such fractions. Chemical and multiphase equilibriums are of utmost importance; hence, the most significant ones involving heavy petroleum fluids are determined and illustrated using advanced equations of state such as sPC-SAFT and EoS/GE. The included phase equilibriums are phase envelopes of reservoir fluids, asymmetric mixtures between light solvents and bitumen including the presence of water and asphaltenes, among others. Besides, heavy petroleum fluids are analyzed from the Newtonian and non-Newtonian viewpoints, exploring their complex rheological behavior. Finally, complemented by online an Excel program for the thermodynamic characterization of unidentifiable petroleum fractions, this book is a useful resource for engineers and researchers in the petroleum industry and is also of interest to students studying chemical and petroleum engineering.

Thermoplastic Processing of Structural Metallic Materials: Experiments, Theory, and Modeling (SpringerBriefs in Materials)
by Serhii Sheyko Yurii Belokon Oleksii Hrechanyi Tetyana VasilchenkoThis book discusses the scientific framework of thermoplastic deformation of structural metallic materials, in particular dual-phase steels and intermetallic alloys, emphasizing the attainment of desired alloy structures and properties through enhanced production techniques. By strategically manipulating the stress-strain state, a more uniform deformation is achieved, thereby fostering structural and property homogeneity. A novel experimental-theoretical approach is presented for correlating the stress-strain state with grain size and metal flow stress. Through extensive experimentation, flow curve dependencies and deformation resistance under varying temperature-velocity conditions are meticulously examined, facilitating their integration into specialized software platforms. Analytical formulations derived from experimental data enable the calculation of deformation resistance for special alloys and the establishment of optimal thermoplastic processing parameters. Aimed at scientific and technical professionals, as well as experts in metallurgy and materials science, this book offers invaluable insights into the advancement of alloy processing methodologies.

Thermospheric Density and Wind Determination from Satellite Dynamics
by Eelco DoornbosThe Earth's atmosphere is often portrayed as a thin and finite blanket covering our planet, separate from the emptiness of outer space. In reality, the transition is gradual and a tiny fraction of the atmophere gases is still present at the altitude of low orbiting satellites. The very high velocities of these satellites ensure that their orbital motion can still be considerably affected by air density and wind. This influence can be measured using accelerometers and satellite tracking techniques. The opening chapters of this thesis provide an excellent introduction to the various disciplines that are involved in the interpretation of these observations: orbital mechanics, satellite aerodynamics and upper atmospheric physics. A subsequent chapter, at the heart of this work, covers advances in the algorithms used for processing satellite accelerometry and Two-Line Element (TLE) orbit data. The closing chapters provide an elaborate analysis of the resulting density and wind products, which are generating many opportunities for further research, to improve the modelling and understanding of the thermosphere system and its interactions with the lower atmosphere, the ionosphere-magnetosphere system and the Sun.

They Are Soldiers (Nathan Dixon #4)
by Harold CoyleFrom Harold Coyle, the New York Times bestselling author of Twice the Citizen, comes the fourth book in the Nathan Dixon series: They Are SoldiersThey are your neighbor and the person who delivers your mail. They teach your children and build your homes. Every day you see them but do not notice them, that is not until they are needed. Only when disasters strike, whether it be natural or man made do they become something quite different, something more than a fellow citizen. Throughout our nation's history they have been called many things; the militia, the home guard, the National Guard. But regardless of their title they have always been unique, something more than ordinary people. Their willingness to be both a good citizen in peace and a warrior when called upon make them soldiers. The nature of the mission, to man a security zone that separates the nation of Israel from the newly created Palestinian state present him and the Guardsmen of Company A with a unique set of problems few are able to predict. Together the professional officer and the citizen soldiers he leads must find a way to navigate their way toward an uncertain future in a troubled land. Part of that future involves dealing with those who are determined to use the arrival of the Americans to further their own political and personal goals. One of these men is Hammed Kamel, a microbiologist who seizes upon the introduction of American forces in a place some still call the Holy Lands as an opportunity to strike a telling blow against the two nations who have oppressed his people, the Palestinians for decades. Together with a crops of like minded men, Kamel sets in motion a train of events that places the citizen soldiers of Bedlow, Virginia and their community on the other side of the world in jeopardy.At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.
They Know Everything About You: How Data-Collecting Corporations and Snooping Government Agencies Are Destroying Democracy
by Robert Scheer Sara BeladiThey Know Everything About You is a groundbreaking exposé of how government agencies and tech corporations monitor virtually every aspect of our lives, and a fierce defense of privacy and democracy. The revelation that the government has access to a vast trove of personal online data demonstrates that we already live in a surveillance society. But the erosion of privacy rights extends far beyond big government. Intelligence agencies such as the NSA and CIA are using Silicon Valley corporate partners as their data spies. Seemingly progressive tech companies are joining forces with snooping government agencies to create a brave new world of wired tyranny. Life in the digital age poses an unprecedented challenge to our constitutional liberties, which guarantee a wall of privacy between the individual and the government. The basic assumption of democracy requires the ability of the individual to experiment with ideas and associations within a protected zone, as secured by the Constitution. The unobserved moment embodies the most basic of human rights, yet it is being squandered in the name of national security and consumer convenience. Robert Scheer argues that the information revolution, while a source of public enlightenment, contains the seeds of freedom’s destruction in the form of a surveillance state that exceeds the wildest dream of the most ingenious dictator. The technology of surveillance, unless vigorously resisted, represents an existential threat to the liberation of the human spirit.
