Harvard system

There are two main referencing systems in use in universities. One of these uses a numbering system in the text with notes at the end of the chapter or article this system often also uses extensive footnoting, and a bibliography is included of works that have been used during the writing of the text. The alternative system that we illustrate above and below is called the Harvard system its use is widespread across many different academic fields of study. In this system the author s name and the date of publication are given in parentheses in the text and refer to a section at the end of the publication, headed References, which in turn contains details of all the published works that have been referenced. We use this system in this book. The Harvard system looks like this ... [Pg.65]

In 1967, work was presented from a Sheffield group on indexing chemical reactions for database budding. In 1969, a Harvard group presented its first steps in the development of a system for computer-assisted synthesis design. Soon afterwards, groups at Brandeis University and TU Munich, Germany, presented their work in this area. [Pg.11]

The use of computers for the design of chemical syntheses was first demonstrated by Corey and Wipke in 1969 with their program OCCS [30]. The successor to OCCS, LHASA [31], is generally considered to be the first synthon-based system. Its development is still going on. Currently, three groups are working on LHASA, one at Harvard University, USA [32], one at the University of Leeds, UK [33], and... [Pg.573]

The task of relating carbohydrate configurations to names requires either a world class memory or an easily recalled mnemonic A mnemonic that serves us well here was pop ularized by the husband-wife team of Lours F Fieser and Mary Fieser of Harvard Uni versity m their 1956 textbook Organic Chemistry As with many mnemonics it s not clear who actually invented it and references to this particular one appeared m the chem ical education literature before publication of the Fiesers text The mnemonic has two features (1) a system for setting down all the stereoisomeric d aldohexoses m a logical order and (2) a way to assign the correct name to each one... [Pg.1032]

Ronald Breslow (Co-Chair) is University Professor of Chemistry, Columbia University, and a founder of a new pharmaceutical company. He received his B.A. (1952), M.A. (1954), and Ph.D. (1955) from Harvard University. His research area is organic chemistry with specialization in biochemical model systems, biomimetic synthetic methods, reaction mechanisms, and aromaticity and antiaromaticity. He served as president of the American Chemical Society in 1996 and has authored a book for the general public, Chemistry Today and Tomorrow The Central, Useful, and Creative Science. He is a member of the National Academy of Sciences, the American Academy of Arts and Sciences, and the American Philosophical Society. He received the U.S. National Medal of Science in 1991. [Pg.197]

Quotation from Sommerfeld, Atomic Structures, 79. On p. vi, Sommerfeld notes that in the chapter on the natural system of the elements, "the former discussions of molecular models and atomic volumes have been thoroughly pared down." At Harvard in 1925, Edwin Kemble s course in quantum mechanics included the second edition of Sommerfeld s Aufbau, according to Schweber (1990 348). Similarly, Joseph Hirschfelder was reading it as an undergraduate at Yale according to Hirschfelder, "My Adventures in Theoretical Chemistry," Ann.Rev.P.Chem. 33 (1983) 129, on 4. [Pg.246]

Hypercube, Inc. at http //www.hyper.com offers molecular modeling packages under the HyperChem name. HyperChem s newest version, Hyper-Chem Release 7.5, is a full 32-bit application, developed for the Windows 95, 98, NT, ME, 2000, and XP operating systems. Density Functional Theory (DFT) has been added as a basic computational engine to complement Molecular Mechanics, Semiempirical Quantum Mechanics and ab initio Quantum Mechanics. The DFT engine includes four combination or hybrid functions, such as the popular B3-LYP or Becke-97 methods. The Bio+ force field in HyperChem represents a version of the Chemistry at HARvard using Molecular Mechanics (CHARMM) force field. Release 7.5 of HyperChem updates... [Pg.177]

In addition to the commercially available systems, several authors have described laboratory-built systems using commercially available components from companies such as Upchurch Scientific (Oak Harbor, WA). One of the first reported laboratory-built micro-bore HPLC systems was described by Simpson and Brown, which was a simple adaptation of a standard HPLC system to accept micro-bore columns built from guard columns. A complete system has been described based on dual microdialysis syringe pumps (CMA Microdialysis, Chelmsford, M A) or dual syringe pumps (Harvard Apparatus, Inc., Holliston, MA), a microinjection port, and a micro-column the latter components being obtained from Upchurch scientific (Figure 3.5). This system was coupled with a laser-induced fluorescence (LIF) detector and used to measure neuropeptides in sub-microliter samples. A further modification of this system was built to perform immunoaffinity isolations of biomedically important analytes from clinical samples. ... [Pg.79]
