"A harrowing rescue thriller with a truly magnetic hero at its core." -BestThrillers A kidnapper hiding in plain sight. A rural town with tons of suspects. From debut author Cam Torrens comes a gut-wrenching suspense novel based on an actual missing person case. A 911 call sends Search & Rescue on a search for a missing girl in the Collegiate Peaks. They find a child...but not the one they seek. Air Force pilot Tyler Zahn's life disintegrated when he lost his son. He discarded his family, his career, and his dignity, finding solace in apathy and beer. Eight years later, armed with new confidence, he invites his estranged daughter, Daria, to visit his Rocky Mountain home. Zahn tries too hard to mend their relationship, and as the tension between father and daughter increases, forgiveness seems out of reach. Especially when his Search & Rescue work pulls him away from Daria and she finds romance at the church camp next door. But Zahn can't get the missing girl he found-and the one he can't find-out of his mind. Someone in this mountain valley is collecting children, and Zahn is gradually drawn into the case while still trying to break through to his daughter. Then she disappears too.
The notions of torsion and torsion freeness have played a very important role in module theory--particularly in the study of modules over integral domains. Furthermore, the use of homological techniques in this connection has been well established. It is the aim of this paper to extend these techniques and to show that this extension leads naturally to several new concepts (e.g. k-torsion freeness and Gorenstein dimension) which are useful in the classification of modules and rings.
The Affordable Care Act (ACA), the sweeping health care reform enacted by the Obama Administration in 2010, continues to be a contentious policy at the center of highly polarized political debates. Both before and after the law’s passage, political elites on both sides of the issue attempted to sway public opinion through two traditional approaches: messaging and policymaking itself. They operated under the assumption that the public’s personal experiences toward the law would make them more favorable. Yet these tried-and-true methods have had limited influence on public attitudes toward the ACA. Public opinion towards the ACA remained stable from 2010 to 2016, with more Americans opposing the law than supporting it. It was only after Donald Trump was elected in 2016 and the prospect of the law being repealed became a reality that public opinion swung in favor of the ACA. If traditional methods of influencing public opinion had little impact on attitudes towards the ACA, what did? In Stable Condition, political scientist Daniel J. Hopkins draws on survey data from 2009 to 2020 to assess how a variety of factors such as personal experience, political messaging, and partisanship did or did not affect public opinion on the ACA. Hopkins finds that although personal experience with the ACA’s Medicaid expansion increased favorability among low-income Americans, it did not have a broader overall impact on public opinion. Personal experience with the Health Insurance Marketplace did not increase wider support for the ACA either. Due to the complex nature of the law, users of the Marketplace often did not realize they were benefiting from the ACA. Therefore, perceptions of the Marketplace were shaped by high-profile issues with the enrollment website and opposition to the individual mandate. These experiences ultimately offset one another, resulting in little discernable change in public opinion overall. Hopkins argues that political polarization was also responsible for elite’s limited influence and that public opinion on the ACA was largely determined by partisanship and political affiliation. Americans quickly aligned with their party’s stance on the law and were resistant to changing their beliefs despite the efforts of political elites. Stable Condition is an illuminating examination of the limits of elites’ influence and the forces that shaped public opinion about the Affordable Care Act.
Stable radicals - molecules with odd electrons which are sufficiently long lived to be studied or isolated using conventional techniques - have enjoyed a long history and are of current interest for a broad array of fundamental and applied reasons, for example to study and drive novel chemical reactions, in the development of rechargeable batteries or the study of free radical reactions in the body. In Stable Radicals: Fundamentals and Applied Aspects of Odd-Electron Compounds a team of international experts provide a broad-based overview of stable radicals, from the fundamental aspects of specific classes of stable neutral radicals to their wide range of applications including synthesis, materials science and chemical biology. Topics covered include: triphenylmethyl and related radicals polychlorinated triphenylmethyl radicals: towards multifunctional molecular materials phenalenyls, cyclopentadienyls, and other carbon-centered radicals the nitrogen oxides: persistent radicals and van der Waals complex dimers nitroxide radicals: properties, synthesis and applications the only stable organic sigma radicals: di-tert-alkyliminoxyls. delocalized radicals containing the hydrazyl [R2N-NR] unit metal-coordinated phenoxyl radicals stable radicals containing the thiazyl unit: synthesis, chemical, and materials properties stable radicals of the heavy p-block elements application of stable radicals as mediators in living-radical polymerization nitroxide-catalyzed alcohol oxidations in organic synthesis metal-nitroxide complexes: synthesis and magneto-structural correlations rechargeable batteries using robust but redox-active organic radicals spin labeling: a modern perspective functional in vivo EPR spectroscopy and imaging using nitroxides and trityl radicals biologically relevant chemistry of nitroxides Stable Free Radicals: Fundamentals and Applied Aspects of Odd-Electron Compounds is an essential guide to this fascinating area of chemistry for researchers and students working in organic and physical chemistry and materials science.
This book serves as a standard reference, making this area accessible not only to researchers in probability and statistics, but also to graduate students and practitioners. The book assumes only a first-year graduate course in probability. Each chapter begins with a brief overview and concludes with a wide range of exercises at varying levels of difficulty. The authors supply detailed hints for the more challenging problems, and cover many advances made in recent years.
The use of Compound-specific Stable Isotope Analysis (CSIA) is increasing in many areas of science and technology for source allocation, authentication, and characterization of transformation reactions. Until now, there have been no textbooks available for students with an analytical chemical background or basic introductory books emphasising the instrumentation and theory. This book is the first to focus solely on stable isotope analysis of individual compounds in sometimes complex mixtures. It acts as both a lecture companion for students and a consultant for advanced scientists in fields including forensic and environmental science. The book starts with a brief history of the field before going on to explain stable isotopes from scratch. The different ways to express isotope abundances are introduced together with isotope effects and isotopic fractionation. A detailed account of the required technical equipment and general procedures for CSIA is provided. This includes sections on derivatization and the use of microextraction techniques in GC-IRMS. The very important topic of referencing and calibration in CSIA is clearly described. This differs from approaches used in quantitative analysis and is often difficult for the newcomer to comprehend. Examples of successful applications of CSIA in food authenticity, forensics, archaeology, doping control, environmental science, and extraterrestrial materials are included. Applications in isotope data treatment and presentation are also discussed and emphasis is placed on the general conclusions that can be drawn from the uses of CSIA. Further instrumental developments in the field are highlighted and selected experiments are introduced that may act as a basis for a short practical course at graduate level.
