DOWNLOAD EBOOK →Intermediate Logic fills a serious gap in the range of university logic texts by offering a clear, reliable, general guide for students taking a second course in logic after completing a basic introduction. It will serve as an ideal follow-up to any of the standard introductory texts, and will give excellent preparation for advanced work in logical theory or applications of logic in philosophy, mathematics, or computing theory. - ;Intermediate Logic is an ideal text for anyone who has taken a first course in logic and is progressing to further study. It examines logical theory, rather than the applications of logic, and does not assume any specific technological grounding. The author introduces and explains each concept and term, ensuring that readers have a firm foundation for study. He provides a broad, deep understanding of logic by adopting and comparing a variety of different methods and approaches. In the first section, Bostock covers such fundamental notions as truth, validity, entailment, quantification, and decision procedures. Part two lays out a definitive introduction to four key logical tools or procedures: semantic tableaux, axiomatic proofs, natural deduction, and sequent calculi. The final section opens up new areas of existence and identity, concluding by moving from orthodox logic to examination of `free logic'. Intermediate Logic provides an ideal secondary course in logic for university students, and a bridge to advanced study of such subjects as model theory, proof theory, and other specialized areas of mathematical logic. -

DOWNLOAD EBOOK →This title was first published in 2000: Intermediate quantifiers express logical quantities which fall between Aristotle's two quantities of categorical propositions - universal and particular. "Few", "many" and "most" express the most commonly referred to intermediate quantifiers, but this book argues that an infinite number can be understood through a deeper examination of the logical nature of all intermediate quantifiers. Presenting and analyzing the logical and linguistic features of intermediate quantifiers, in a fashion typical of traditional logic, Philip L. Peterson presents an account integrating the logic and semantics of intermediate quantifiers with the two traditional quantities by traditional methods. Having introduced the basic idea of how to approach the task in the first chapter, with heavy emphasis on the linguistic meanings and ordinary uses of English intermediate quantifier expressions, Peterson then undertakes the task of completely integrating the three basic intermediate quantities into traditional logic in the following chapter.

DOWNLOAD EBOOK →Research on cytoskeletal elements of eukaryotic cells has been expand ing explosively during the past 5 to 10 years. Due largely to the employment of electron and immunofluorescent microscopy, significant results have been obtained which have provided interesting new insights into the dynamics of nucleated cells at the structural, physiological, as well as developmental levels. While a substantial amount of knowledge has accumulated on the function of microfilaments and microtubules, the roles of the third major class of cytoskeletal structures in vertebrate cells, the intermediate filaments, have largely resisted clarification. The investigation of cultured cells and of tissues from various developmental stages has furnished a host of information on the inter-and intracellular distribution of the different types of intermediate filaments and led to the contention that they have a structural and organizing function in the cytoplasm of vertebrate cells. However, the results of recent experimen that vertebrate cells can function perfectly in the tation have shown complete absence of cytoplasmically extended intermediate filament meshworks. It is legitimate to suppose, therefore, that their function in vertebrate cells is much more subtle and complex than generally presumed. Our interest in the structure and function of intermediate filament proteins was initiated approximately 7 years ago while working on the regulation of macromolecular synthesis in picornavirus-infected mam malian cells. In attempts to demonstrate virus-induced changes in the nuclear protein components of the host cells, the nonionic detergent extraction method was used to purify nuclei.

DOWNLOAD EBOOK →Most reactions in organic chemistry do not proceed in a single step but rather take several steps to yield the desired product. In the course of these multi-step reaction sequences, short-lived intermediates can be generated that quickly convert into other intermediates, reactants, products or side products. As these intermediates are highly reactive, they cannot usually be isolated, but their existence and structure can be proved by theoretical and experimental methods. Using the information obtained, researchers can better understand the underlying reaction mechanism of a certain organic transformation and thus develop novel strategies for efficient organic synthesis. The chapters are clearly structured and are arranged according to the type of intermediate, providing information on the formation, characterization, stereochemistry, stability, and reactivity of the intermediates. Additionally, representative examples and a problem section with different levels of difficulty are included for self-testing the newly acquired knowledge. By providing a deeper understanding of the underlying concepts, this is a musthave reference for PhD and Master Students in organic chemistry, as well as a valuable source of information for chemists in academia and industry working in the field. It is also ideal as primary or supplementary reading for courses on organic chemistry, physical organic chemistry or analytical chemistry.
