Polaris

by Mindee Arnett

Jeth Seagrave and his crew of mercenaries are pulled into one last high-stakes mission in this breathtaking sequel to Mindee Arnett's Avalon, which SLJ called, in a starred review, "an exciting piece of science fiction that keeps up its energy from beginning to end."Jeth Seagrave and his crew are on the run. The ITA, still holding Jeth's mother in a remote research lab, is now intent on acquiring the metatech secrets Jeth's sister Cora carries inside her DNA, and Jeth is desperate to find the resources he needs to rescue his mother and start a new life outside the Confederation. But the ITA is just as desperate, and Jeth soon finds himself pursued by a mysterious figure hell-bent on capturing him and his crew--dead or alive.With nowhere to run and only one play left, Jeth enters into a bargain with the last person he ever thought he'd see again: Daxton Price, the galaxy's newest and most fearsome crime lord. Dax promises to help Jeth, but his help will only come at a price--a price that could mean sacrificing everything Jeth has fought for until now.

Polaritonic Chemistry: Manipulating Molecular Structure Through Strong Light–Matter Coupling (Springer Theses)

by Javier Galego Pascual​

Polaritonic chemistry is an emergent interdisciplinary field in which the strong interaction of organic molecules with confined electromagnetic field modes is exploited in order to manipulate the chemical structure and reactions of the system. In the regime of strong light-matter coupling the interaction with the electromagnetic vacuum obliges us to redefine the concept of a molecule and consider the hybrid system as a whole. This thesis builds on the foundations of chemistry and quantum electrodynamics in order to provide a theoretical framework to describe these organic light-matter hybrids. By fully embracing the structural complexity of molecules, this theory allows us to employ long-established quantum chemistry methods to understand polaritonic chemistry. This leads to predictions of substantial structural changes in organic molecules and the possibility of significantly influencing chemical reactions both in the excited and ground states of the system.

Polarization Theory of Nuclear Reactions

by Qing-Biao Shen

This book provides the reader with a modern and comprehensive overview of nuclear polarization theory. The understanding of polarization phenomena greatly enriches data obtained from scattering and nuclear reactions by providing information on the interaction that can change spin orientation as well as important verification data for the study of nuclear structures and reaction mechanisms. The author methodically derives the polarization theory of nuclear reactions for various types of elastic scattering and two-body direct reactions between particles of different spin and unpolarized target nuclei with arbitrary spin, as well as the reactions between two polarized light particles and the polarization theory for photon beams. In addition, the polarization theories of relativistic nuclear reactions are rigorously covered in great scope and detail. A chapter on polarized particle transport theory presents the Monte-Carlo method for describing the transport of polarized particles and formalizes the polarized particle transport equation. Here, the author also illustrates a novel and concrete scheme for establishing a polarization nuclear database. Nuclear polarization is important not only for microscopic nuclear structure and reaction studies but also for nuclear engineering, applied nuclear physics, and medical physics. With the development of radioactive beam facilities and, on the theoretical side, the development of consistent microscopic nuclear reaction and structure theories, this book on the polarization theory of nuclear reactions serves as a timely source of reference for students and researchers alike.

Birgit und Kristian Schlegel gehen in ihrem reich illustrierten Buch den historischen Erklärungen zur Entstehung der Polarlichter nach, deren Rätsel erst im 20. Jahrhundert physikalisch ganz gelöst wurde. Aktuelle interdisziplinäre Forschungsergebnisse, die mit der Entstehung der Polarlichter in Verbindung stehen, werden anschaulich und wissenschaftlich präzise anhand zahlreicher Bilder und Diagramme erläutert.

Pole Solutions for Flame Front Propagation

by Oleg Kupervasser

This book deals with solving mathematically the unsteady flame propagation equations. New original mathematical methods for solving complex non-linear equations and investigating their properties are presented. Pole solutions for flame front propagation are developed. Premixed flames and filtration combustion have remarkable properties: the complex nonlinear integro-differential equations for these problems have exact analytical solutions described by the motion of poles in a complex plane. Instead of complex equations, a finite set of ordinary differential equations is applied. These solutions help to investigate analytically and numerically properties of the flame front propagation equations.

Police and Profiling in the United States: Applying Theory to Criminal Investigations

by Lauren M. Barrow Ron A. Rufo Saul Arambula

It examines theories on criminal behavior, describes how to develop typologies based on different criminal characteristics, examines the critical role of crime scenes, and concludes with scintillating profiles of 13 of the most notorious serial killers.

Police and Society in Brazil (Advances in Police Theory and Practice)

by Vicente Riccio Wesley G. Skogan

In Brazil, where crime is closely associated with social inequality and failure of the criminal justice system, the police are considered by most to be corrupt, inefficient, and violent, especially when occupying poor areas, and they lack the widespread legitimacy enjoyed by police forces in many nations in the northern hemisphere. This text covers hot-button issues like urban pacification squads, gangs, and drugs, as well as practical topics such as policy, dual civil and military models, and gender relations. The latest volume in the renowned Advances in Police Theory and Practice Series, Police and Society in Brazil fills a gap in English literature about policing in a nation that currently ranks sixth in number of homicides. It is a must-read for criminal justice practitioners, as well as students of international policing.
