Precursor by C. J. Cherryh Pdf

The fourth novel in Cherryh’s Foreigner space opera series, a groundbreaking tale of first contact and its consequences… Over three years have passed since the reappearance of the starship Phoenix, which two centuries before left an isolated colony of humans on the world of the volatile atevi. Since that time, humans have lived in exile on the island of Mospheira; but the unexpected return of the Phoenix has shattered the fragile political balance of these two nearly incompatible races. For the captains of the Phoenix offer the atevi something the Mospheiran humans never could—access to the stars. For three breakneck years the atevi labor to build a space shuttle which will bear their representatives to the Phoenix, to strengthen connections with their new human allies and retain their bid for control of their world. But as soon as the shuttle proves spaceworthy, the captains of the Phoenix suddenly recall their planetary delegates, breaking diplomatic contact and initiating a vicious bid for political dominance. But the powerful head of the atevi's Western Association is not to be outmaneuvered, and he sends his own diplomat, or paidhi, Bren Cameron, into space to negotiate. Thrust into a political maelstrom with almost no preparation, can Bren gain control of the station and political supremacy for the atevi without sparking a three-sided interspecies war? The long-running Foreigner series can also be enjoyed by more casual genre readers in sub-trilogy installments. Precursor is the 4th Foreigner novel. It is also the 1st book in the second subtrilogy.

The Dark Precursor by Paulo de Assis,Paolo Giudic Pdf

Deleuze’s and Guattari’s philosophy in the field of artistic research Gilles Deleuze’s intriguing concept of the dark precursor refers to intensive processes of energetic flows passing between fields of different potentials. Fleetingly used in Difference and Repetition, it remained underexplored in Deleuze’s subsequent work. In this collection of essays numerous contributors offer perspectives on Deleuze’s concept of the dark precursor as it affects artistic research, providing a wide-ranging panorama on the intersection between music, art, philosophy, and scholarship. The forty-eight chapters in this publication present a kaleidoscopic view of different fields of knowledge and artistic practices, exposing for the first time the diversity and richness of a world situated between artistic research and the philosophy of Gilles Deleuze and Félix Guattari. Within different understandings of artistic research, the authors—composers, architects, performers, philosophers, sculptors, film-makers, painters, writers, and activists—map practices and invent concepts, contributing to a creative expansion of horizons, materials, and methodologies.

The Shadow of the Precursor by Nena Bierbaum Pdf

A shadow, in its most literal sense, is the projection of a silhouette against a surface and the obstruction of direct light from hitting that surface. For writers and artists, the shadows cast by their precursors can be either a welcome influence, one consciously evoked in textual production via homage or bricolage, or can manifest as an intrusive, haunting, prohibitive presence, one which threatens to engulf the successor. Many writers and artists are affected by an anxious and ambiguous relationship with their precursors, while others are energised by this relationship. The role that intertextuality plays in creative production invites interrogation, and this publication explores a range of conscious and unconscious influences informing relations between texts and contexts, between predecessors and successors. The chapters revolve around intertextual influence, ranging from conscious imitation and intentional allusion to Julia Kristeva’s idea of intertextuality. Do all texts contain references to and even quotations from other texts? Do such references help shape how we read? This multidisciplinary work includes chapters on the long shadows cast by Shakespeare, Dante, Scott, Virgil and Ovid, the shadows of colonial precursors on postcolonial successors, the shadows cast over Kipling and Murdoch, and chapters on other writers, dramatists and filmmakers and their relationships with precursor figures. With its focus on intertextual relationships, this book contributes to the thriving fields of adaptation studies and studies of intertextuality.

Amyloid Protein Precursor in Development, Aging and Alzheimer’s Disease by C.L. Masters,K. Beyreuther,Marc Trillet Pdf

This book summarizes the last ten years' research on Alzheimer's disease. Genetic mutations in the gene which codes for amyloid precursor protein (APP) have now been shown to cause Alzheimer's disease in some families. Other genetic loci are now being discovered which relate to Alzheimer's disease in some families. Understanding the normal structure and function of the APP gene product will eventually provide avenues for developing specific therapeutic strategies targeted at the amyloid deposition in the Alzheimer's disease brain. Drugs which can inhibit or dissolve the amyloid, affect the synthesis and proteolysis of APP, or which regulate the activity of the APP gene all hold the promise of eventually yielding an effective treatment for Alzheimer's disease.

Precursor Math Concepts by Mary Hynes-Berry,Jie-Qi Chen,Barbara Abel Pdf

This groundbreaking book looks at the development of mathematical thinking in infants and toddlers, with an emphasis on the earliest stage, from zero to three, when mathematical thinking and problem solving first emerge as natural instincts. The text explores the four precursor math concepts--Attribute, Comparison, Change, and Pattern--with an emphasis on how development occurs when it is nurtured by loving knowledgeable others. The authors call this the CAIR principle: Closely Attend & Intentionally Respond. Sharing their stories of working with a wide range of zero to three caregivers and educators, the authors stress the difference between arithmetic skills and their definition of mathematics as "a logical way of thinking that allows for increasing precision." Each user-friendly chapter includes suggestions for highly effective practices that are embedded into everyday interactions and routines. Early care providers can use this resource to develop young children's interest in mathematics, ensuring that they are ready for the big ideas they will encounter in preschool. Book Features: Combines the most current research on infant and toddler cognitive development in relation to mathematical thinking. Offers concrete ways to help caregivers and professionals draw out the math that is all around us. Blends three domains of human development--social-emotional, physical, and cognitive. Examines the What, Who, and How of each precursor concept, with authentic anecdotes and "What the Research Says" sections.

Deleuze, The Dark Precursor by Eleanor Kaufman Pdf

A thoughtful and original analysis of the writings of influential French philosopher Gilles Deleuze. Gilles Deleuze is considered one of the most important French philosophers of the twentieth century. Eleanor Kaufman situates Deleuze in relation to others of his generation, such as Jean-Paul Sartre, Pierre Klossowski, Maurice Blanchot, and Claude Lévi-Strauss, and she engages the provocative readings of Deleuze by Alain Badiou and Slavoj Žižek. Deleuze, The Dark Precursor is organized around three themes that critically overlap: dialectic, structure, and being. Kaufman argues that Deleuze's work is deeply concerned with these concepts, even when he advocates for the seemingly opposite notions of univocity, nonsense, and becoming. By drawing on scholastic thought and reading somewhat against the grain, Kaufman suggests that these often-maligned themes allow for a nuanced, even positive reflection on apparently negative states of being, such as extreme inertia. This attention to the negative or minor category has implications that extend beyond philosophy and into feminist theory, film, American studies, anthropology, and architecture.

Accident Precursor Analysis and Management by National Academy of Engineering Pdf

In the aftermath of catastrophes, it is common to find prior indicators, missed signals, and dismissed alerts that, had they been recognized and appropriately managed before the event, could have resulted in the undesired event being averted. These indicators are typically called "precursors." Accident Precursor Analysis and Management: Reducing Technological Risk Through Diligence documents various industrial and academic approaches to detecting, analyzing, and benefiting from accident precursors and examines public-sector and private-sector roles in the collection and use of precursor information. The book includes the analysis, findings and recommendations of the authoring NAE committee as well as eleven individually authored background papers on the opportunity of precursor analysis and management, risk assessment, risk management, and linking risk assessment and management.

Nanomaterials via Single-Source Precursors by Allen W. Apblett,Andrew R. Barron,Aloysius F. Hepp Pdf

Nanomaterials via Single-Source Precursors: Synthesis, Processing and Applications presents recent results and overviews of synthesis, processing, characterization and applications of advanced materials for energy, electronics, biomedicine, sensors and aerospace. A variety of processing methods (vapor, liquid and solid-state) are covered, along with materials, including metals, oxides, semiconductor, sulfides, selenides, nitrides, and carbon-based materials. Production of quantum dots, nanoparticles, thin films and composites are described by a collection of international experts. Given the ability to customize the phase, morphology, and properties of target materials, this “rational approach to synthesis and processing is a disruptive technology for electronic, energy, structural and biomedical (nano)materials and devices. The use of single-source chemical precursors for materials processing technology allows for intimate elemental mixing and hence production of complex materials at temperatures well below traditional physical methods and those involving direct combination of elements. The use of lower temperatures enables thin-film deposition on lightweight polymer substrates and reduces damage to complex devices structures such as used in power, electronics and sensors. Discusses new approaches to synthesis or single-source precursors (SSPs) and the concept of rational design of materials Includes materials processing of SSPs in the design of new materials and novel devices Provides comprehensive coverage of the subject (materials science and chemistry) as related to SSPs and the range of potential applications

Optical Precursors by Jiefei Chen,Heejeong Jeong,Michael MT Loy,Shengwang Du Pdf

Ever since Einstein’s special relativity in 1905, the principle of invariant light speed in vacuum has been attracting attention from a wide range of disciplines. How to interpret the principle of light speed? Is light referred to continuous light, or light pulse with definite boundaries? Recent discovery of superluminal medium triggered vigorous discussion within the Physics community. Can communication via such “superluminal channel” break the speed limit and thus violate causality principle? Or, will a single photon, which is not governed by classical laws of Physics, tend to break the speed limit? To solve these problems, this Brief brings in Optical Precursors, the theoretical works for which started as early as 1914. This is a typical optical phenomenon combining wave propagation theory and light-wave interaction. Both theory and experimental works are covered in this Brief. The study of precursor verifies that the effective information carried by light pulses can never exceed the speed of light in vacuum- c. Further, through observation from nonclassical single photon source, the precursor rules out the probability of a single photon traveling with the speed, breaking the classical limit.

Chemical vapour deposition of boron-carbon thin films from organoboron precursors by Maiwulidan (Mewlude) Yimamu (Imam) Pdf

Boron-carbon (BxC) thin films enriched in 10B are potential neutron converting layers for 10Bbased solid-state neutron detectors given the good neutron absorption cross-section of 10B atoms in the thin film. Chemical Vapour Deposition (CVD) of such films faces the challenge that the maximum temperature tolerated by the aluminium substrate is 660 °C and low temperature CVD routes for BxC films are thus needed. This thesis presents the use of two different organoboron precursors, triethylboron –B(C2H5)3 (TEB) and trimethylboron – B(CH3)3 (TMB) as single-source precursors for CVD of BxC thin films. The CVD behaviour of TEB in thermal CVD has been studied by both BxC thin film deposition and quantum chemical calculations of the gas phase chemistry at the corresponding CVD conditions. The calculations predict that the gas phase reactions are dominated by ?-hydride eliminations of C2H4 to yield BH3. In addition, a complementary bimolecular reaction path based on H2-assisted C2H6 elimination to BH3 is also present at lower temperatures in the presence of hydrogen molecules. A temperature window of 600 – 1000 °C for deposition of X-ray amorphous BxC films with 2.5 ? x ? 4.5 is identified showing good film density (2.40 – 2.65 g/cm3) which is close to the bulk density of crystalline B4C, 2.52 g/cm3 and high hardness (29 – 39 GPa). The impurity level of H is lowered to < 1 at. % within the temperature window. Plasma chemical vapour deposition has been studied using TMB as single-source precursor in Ar plasma for investigating BxC thin film deposition at lower temperature than allowed by thermal CVD and further understanding of thin film deposition process. The effect of plasma power, total pressure, TMB and Ar gas flow on film composition and morphology are investigated. The highest B/C ratio of 1.9 is obtained at highest plasma power of 2400 W and TMB flow of 7 sccm. The H content in the films seems constant at 15±5 at. %. The B-C bond is dominant in the films with small amount of C-C and B-O bonds, which are likely due to the formation of amorphous carbon and surface oxidation, respectively. The film density is determined as 2.16±0.01 g/cm3 and the internal compressive stresses are measured to be <400 MPa.
