Assembly Instructions for Nucleic Acid Models describes the step-by-step instructions in building a single nucleotide using the Academic Press/Molecular Design Inc. (AP/MDI) models. This booklet also provides instructions for constructing models of the DNA-B (Watson-Crick), DNA-A, and the DNA-Z forms. This text illustrates the chemical composition and atom numbering system of the nucleotide unit, the fundamental building block of all nucleic acids. The framework components include the atomic pieces for phosphorous, oxygen, carbon, nitrogen, and the fused pieces that represent two bases and two furanose rings. Building models of the different nucleic acid structure involves adjustments of seven torsion angles; in the AP/MDI Molecular Model System, only six angles are adjusted. In constructing larger DNA structures, the operator assembles a series of nucleotide units. He should also be familiar with the seven torsion angles of these structures which are composed of six adjustable angles and the correct ring conformation. This guide also contains a table listing the torsion angles for several forms of DNA. This booklet is suitable for students in chemistry, new chemist practioners, professors in chemistry, as well as other researchers whose works involve some chemical investigations and experiments.

Fundamentally, Persons and Liberal Democracy is an explication and defense of classical liberalism. It explains the relatively recent shift in the Church's political theory and, in the process, defends what could be deemed a non-statist form of welfare liberalism. After an introduction, the first chapter contextualizes modern Catholic social thought, explaining how the shift to a nuanced endorsement of liberal economic and political thought was initiated by the pragmatic economic and cultural analyses of nineteenth-century social and liberal Catholics. The next two chapters investigate one fruit of the subsequent re-examination of the relationship of Catholicism to modernity: John Paul's qualified acceptance of liberalism for non-circumstantial, ethical reasons appropriated from within the tradition. While the second chapter details the phenomenological, Thomistic, and theological bases of his ethical premises, the third chapter examines the relationship of these premises to the various aspects of his political theory, particularly his theories of human rights and the complementary roles of the state and civil society in securing these rights. Chapters four and five initiate a dialogue between this analysis of John Paul's social thought and influential political theorists. In the fourth chapter, the dialogue is between John Paul and four Catholic interlocutors: theoconservatives, liberation theologians, United States Conference of Catholic Bishops, and British distributists. The fifth chapter brings John Paul and Catholic social thought into conversation with communitarian critics of liberalism and evaluates the relationship of recent thought on civil society and federalism to the principle of subsidiarity. Finally, the conclusion highlights his most significant accomplishments and suggests areas for further development.

Justice at the Margins of War fills two important gaps in the literature on the ethics of national security affairs. First, while thinking about the justice of warfare is highly developed, justifications of intelligence activities—which can involve lying, manipulation, coercion, stealing and even killing to obtain and defend information—are relatively limited and often conflicting. The authors explore relevant ethical principles and then apply them to specific activities—including agent recruitment, human and technical methods of espionage and counterintelligence, interrogational torture, analysis, covert action, sabotage, and assassination.Second, ethical work on interstate conflict occurring in a “gray zone” between war and peace has only just begun. Gray zone operations—the use of low-level lethal and sublethal means to weaken others—are not new. But technological developments have increased the forms, intensity, and significance of this realm of competition. This volume defines the gray zone and discusses moral challenges associated with various operations—including lethal, economic, information, election, legal, and cyber.
