THE DESIGN OF WAITING AREAS TO OPTIMIZE THE STORAGE CAPACITY IN THE MARINE INTERMODAL TERMINALS
No full textThe appropriate sizing of storage areas to optimize the management of intermodal transport, the adoption of environment protection systems and the appropriate flow’s regulations inside manoeuvre’s zones can solve many problems encountered today in a intermodal marine terminal.
For these reasons the “integrated design” of storage areas for vehicles and containers is considered essential to ensure efficiency and functionality for all harbour-system.
So is here proposed a simulative model as a tool for a more correct design of waiting areas by considering the real stochastic conditions of the process of the arrivals.
For the sizing of areas for containers in the harbours, it is necessary to report the storage capacity in terms of TEU that can be stored (and handled) in the unit of time, e.g. in one year, with the extension of sites for storage of boxes and furniture with the other specific operating parameters.
The sizing of storage areas of the goods date constitutes a delicate problem the frequent shortage of the areas available. The ability to warehouse of the terminal is essentially determined from the interrelation between fixed and static parameters in the short period which the extension of the storage area, the height of the overlapping batteries of container (defined also like number of “shooting”), the means of movements and, at last, a series of parameters that can vary the efficiency’s degree according to of the operatives of the terminal.
The optimal level of use is caught up when it is employed approximately the 60-65% of the maximum storage capacity; account is kept, therefore, of a sure tolerance necessary in order to make forehead to eventual peaks of traffic in the periods in which the volume of container in the terminal or advanced to that mean. By use of the Sartor expression (1997), it is possible to find out the capacity of traffic C of a terminal for container in a period of reference (generally one year) and this can be useful in order to define the requirements of areas to assign to the storage
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Analysis of the railway network operations safety, with of different obstacles along the route, by the study of Buffon-Laplace type problems: The case of infrastructure with irregular hexagonal lattices
Full text linkIn this paper we use an approach based on a Buffon-Laplace type problem for an irregular hexagonal lattice and obstacles to study some problems about analysis of the railway network operations safety in the presence of different obstacles on the route
Interferon-gamma (IFN-gamma) induces programmed cell death in differentiated human leukemic B cell lines.
No full textInterferons (IFNs) are cytokines that exert an antiviral effect on target cells and possess immunomodulatory and antitumor properties. In this study we have investigated the effects of human recombinant IFN-gamma on human leukemic B cell lines at different stages of maturation. Our data show that in Burkitt's lymphoma RAMOS-1 B cells IFN-gamma induces a reduction of cell growth and a clonal selection via programmed cell death; in contrast, IFN-gamma treatment of KM-3 pre-B cells does not induce biochemical and morphological changes as shown by electron microscope analysis and DNA gel electrophoresis
