Thermophysical Properties of Heavy Petroleum Fluids (Petroleum Engineering)

by Bernardo Carreón-Calderón Verónica Uribe-Vargas Juan Pablo Aguayo

This 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.

Thermospheric Density and Wind Determination from Satellite Dynamics

by Eelco Doornbos

The 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 Coyle

From 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 Beladi

They 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.

They Laughed at Galileo

by Albert Jack

They Laughed at Galileo takes a humorous and reflective look at one thousand years of the development of humankind. Those who dreamt, those who taught, those who opposed, and those who, ultimately, did. At some point in modern history each and every one of our inventions and discoveries was thought up in the first place and then developed by a single person, or a handful of people, who dreamt of the seemingly impossible. For them the future was clear and obvious, but for the vast majority, including the acknowledged experts of their day, such belief was sheer folly. For just about everything that has improved our modern lifestyles in a way that our ancestors could not possibly imagine, there was once a dreamer opposed by a team of experts publicly declaring that "It cannot be done." Well, yes it could. The radio, crude oil, show business, high-powered trains and high-flying airplanes, computers, medicine, and nuclear energy-each of these inventions have had a profound effect on the course of human history, and each one was rejected, resisted, and ridiculed by the leading "experts" of the time. Ultimately the inventors and innovators who brought these into existence provided invaluable contributions to science and the culture of humankind.

Thieves of Virtue: When Bioethics Stole Medicine (Basic Bioethics)

by Tom Koch

An argument against the “lifeboat ethic” of contemporary bioethics that views medicine as a commodity rather than a tradition of care and caring.Bioethics emerged in the 1960s from a conviction that physicians and researchers needed the guidance of philosophers in handling the issues raised by technological advances in medicine. It blossomed as a response to the perceived doctor-knows-best paternalism of the traditional medical ethic and today plays a critical role in health policies and treatment decisions. Bioethics claimed to offer a set of generally applicable, universally accepted guidelines that would simplify complex situations. In Thieves of Virtue, Tom Koch contends that bioethics has failed to deliver on its promises. Instead, he argues, bioethics has promoted a view of medicine as a commodity whose delivery is predicated not on care but on economic efficiency.At the heart of bioethics, Koch writes, is a “lifeboat ethic” that assumes “scarcity” of medical resources is a natural condition rather than the result of prior economic, political, and social choices. The idea of natural scarcity requiring ethical triage signaled a shift in ethical emphasis from patient care and the physician's responsibility for it to neoliberal accountancies and the promotion of research as the preeminent good. The solution to the failure of bioethics is not a new set of simplistic principles. Koch points the way to a transformed medical ethics that is humanist, responsible, and defensible.
