No full textSTRESS CONCENTRATION AND FATIGUE LIFE PREDICTION FOR DISKS CENTRIFUGAL SEPARATORS
No full textThe paper presents the continuation of a previous study
( Anghel, Iatan, Pasat, 1998) concerning the elastic analysis of
disk centrifugal separators. The goals are the state of stress
analysis and stress concentration determination in the main critical
junctions of the separator´s bowl, subjected to loads corresponding to
the main technological conditions. Taking into account the cyclic
nature of technological loads (centrifugal forces r omega 2)
standard procedures for estimating the fatigue and residual strength
of the entire bowl are discussed for prediction of the lifetime. The
numerical results presented were obtained for a real small
separators bowl. Two numerical analyses were developed to identify
the critical junctions of the bowl due to the main loads: central
axial load (Fa), centrifugal force (r . omega2) and
internal pressure (p). One analysis is based on the extension of the
classical thin shell theory and the flexibility matrix method (
Anghel, Iatan, Pasat, 1998) and the second on the finite element
method (FEM), using a professional package, COSMOS/M Designer II. The
study reveals a reasonable accuracy of the analytical and numerical
results, an accurate positioning of the critical junctions and a great
number of lifetime service cycles. On the other hand, the study may be
a suitable method for preliminary design analysis and load-carrying
capacity prediction of such structures
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Migrants’ Remittances: Channeling Globalization
No full textMigration is a global phenomenon which touches every country in the world as sending, transit or receiving countries. Remittances represent one of the most consistent outcomes of migration. Through remittances, migrants transfer funds, information, ideas and practices. Remittances link societies of origin and destination by multiple processes of mobility and exchange
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
A study of the known and hypothetical crystal structures of pyridine: why are there four molecules in the asymmetric unit cell?
No full textThe oldest crystal structure of pyridine is unusually complex, with four molecules in the asymmetric unit cell of Pna21 symmetry. In an attempt to understand why pyridine crystallises with 16 molecules in the unit cell, we have considered its thermodynamic stability relative to hypothetical pyridine structures. These were generated by a search for minima in the lattice energy of pyridine amongst the more common space groups, using the crystal structure prediction procedure MOLPAK followed by lattice energy minimisation using a distributed multipole-based intermolecular potential. We find over two dozen distinct crystal structures in the energy gap of less than 6 kJ mol?1 between the corresponding models for the observed and most stable (hypothetical) structure. Adding harmonic phonon estimates of the intermolecular zero point energy and entropy at the melting point of pyridine slightly improves the relative stability of the observed Z = 16 structure. Several of these hypothetical structures can be eliminated as only just mechanically stable, or because the growth rate of the crystal is estimated to be very slow by the attachment energy model. Nevertheless, there are still over a dozen structures that appear competitive with the known structure as polymorphs of pyridine. Following these predictions, an intense experimental search has found a new polymorph of perdeutero-pyridine (form II), which was not found in the search. This structure is also predicted to be metastable with a similar energy to form I. Although there is some evidence for kinetic factors favouring the observed structures, the metastable Z = 16 structure and the new form II remain a challenge for our understanding of crystallisatio
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
