    Notes: Summary The active conformation of several histamine H1-antagonists is investigated. As a template molecule we used the antagonist cyproheptadine, which consists of a piperidylene ring connected to a tricyclic system. The piperidylene moiety is shown to be flexible. The global minimum is a chair conformation but, additionally, a second chair and various boat conformations have to be considered, as their energies are less than 5 kcal/mol above the energy of the global minimum. Two semi-rigid histamine H1-antagonists, phenindamine and triprolidine, were fitted onto the various conformations of cyproheptadine in order to derive the pharmacologically active conformation of cyproheptadine. At the same time, the active conformation of both phenindamine and triprolidine was derived. It is demonstrated that, within the receptor-bound conformation of cyproheptadine, the piperidylene ring most probably exists in a boat form.

    Description: Roberto Pettorino was born in Naples on April 24, 1946. After graduating in Physics at the University of Naples Federico II in 1970, he later pursued research at Stanford's SLAC and Geneva's CERN. He was Full Professor of Theoretical Physics at the Faculty of Physical, Mathematical and Natural Sciences at Federico II University, Dean of the Faculty from 2007 to 2012, President of the University Assessment Team since October 2012. Since the first Open Archive was created by Paul Ginsparg in 1991 at the Los Alamos National Laboratory (LANL preprint archive, USA) for the elementary particle physics community, Roberto Pettorino was engaged in promoting Open Access. Since 2002, he had been delegated by the Rector of Naples Federico II for the libraries information services and member of the Scientific Technical Council of the Information Services Center; then he chaired the Permanent Commission for Libraries and Digital Resources. In 2002-2003 he promoted the development of the Digital Library of the University of Naples Federico II. Here are some contributions, collected to celebrate Roberto Pettorino's memory on April 8, 2013 when the Library Center was officially named after him.

    Description: This proceedings e-book contains papers presented at the national Symposium on “Electronic Books and the practices of scholarly research”, held in Naples, Italy, on 20 June 2003. The advent of new technologies, tools, and digital resources is changing how scholars conduct their work, keep updated in their field or fields of study, and think about research. Moving from the reconstruction of the market of scientific communication, copyright policies, and management of long-term conservation strategies, the published papers aim to discuss the ways in which scholarly practices have changed in the last decades, even since the end of the last century, in teaching and in research, in various disciplines like history, phisics and biomedical sciences.
