No full textA phenomenological model of active constrained layers
No full textActive constrained layer (ACL) treatments consist of a layer of viscoelastic material bonded to the host structure and constrained by an actuator. These treatments control vibrations by means of several mechanisms: the actuator increases the dissipation of energy by increasing the shearing in the viscoelastic layer, and simultaneously it controls the vibrations by applying forces to the host structure through the viscoelastic layer. To optimise ACL treatments, it is necessary to understand their physics. While several models in the literature successfully predict the response of structures treated with ACL, the complexity of these models is not well suited for investigating the mechanisms underlying the behaviour of ACL treatments.This paper describes a simple model of beams treated with ACL, which allows analytical investigations of the damping and control mechanisms of ACL treatment. The model is based on a modal approach in which each mode of the structure is represented by a mass–spring system. The two layers of the ACL patch are represented by two springs in series, the control voltage in effect driving one of these springs. A numerical validation indicates that the model accuracy is good for ACL patches whose length is smaller than the wavelength of the beam and located at appropriate positions on the host structure.In order to demonstrate the usefulness of the lumped parameter model to get insight into the behaviour of ACL treatments, the various ACL damping mechanisms are briefly discussed. Results indicate that proportional feedback control is associated with an increase of shearing in the viscoelastic layer, while the action of active forces dominates when derivative feedback is used
Tolerability and efficacy of zuclopenthixol in the treatment of gerontopsychiatric patients - A prospective study
No full textNeuroleptic drugs are of proven value in the therapy of aggression, restlessness and sleep disorders in gerontopsychiatric practice. In a post marketing study (PMS) a total of 241 gerontopsychiatric patients were observed under realistic treatment conditions to evaluate effects and side-effects of zuclopenthixol treatment. Descriptive and interference-statistical methods of efficacy analysis showed a high degree of efficiency of zuclopenthixol in older patients with psychotic symptoms, organic symptoms and/or behavioral disorders. In spite of the relatively high age of the patients and frequent comorbidity and medications, there were only few side-effects of zuclopenthixol

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
Creutzfeldt-Jakob disease and homocysteine levels in plasma and cerebrospinal fluid
No full textBackground: There is evidence that homocysteine contributes to various neurodegenerative disorders. Objective: To assess the values of homocysteine in patients with Creutzfeldt-Jakob disease (CJD) in both cerebrospinal fluid (CSF) and plasma. Methods: Study design: Case control study. Total homocysteine was quantified in CSF and plasma samples of CJD patients (n = 13) and healthy controls (n = 13). Results: Mean values in healthy controls: 0.15 mumol/l +/- 0.07 (CSF) and 9.10 mumol/l +/- 2.99 (plasma); mean values in CJD patients: 0.13 mumol/l +/- 0.03 (CSF) and 9.22 mumol/l +/- 1.81 (plasma). No significant differences between CJD patients and controls were observed (Mann-Whitney U, p > 0.05). Conclusions: The results indicate that the CSF and plasma of CJD patients showed no higher endogenous levels of homocysteine as compared to normal healthy controls. These findings provide no evidence for an additional role of homocysteine in the pathogenetic mechanisms underlying CJD neurodegeneration. Copyright (C) 2005 S. Karger AG, Basel
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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

The distinctly trilobate rostrum immediately distinguishes P. h e t e ro c h ro u s from two congeners, P. militaris and P. scabriculus. Yang (1983) and Yang & Xu (1994) recorded P. militaris from the Xisha and Nansha Islands, China. However, the illustrated specimens seem referable to P. heterochrous on the basis of the characteristic shape of the rostrum. Garth et al. (1987) recorded P. heterochrous as an undescribed species from Enewetak Atoll, Marshall Islands. Distribution. Nansha and Xisha Islands in China, Ryukyu Islands, Mariana Islands, Marshall Islands, Chesterfield Islands; subtidal to 23 m; occurring in crevices in dead coral rubble, dead branching coral, and on the base of living coral (Yang 1983; Kropp 1984; Haig 1987; Yang & Xu 1994; Osawa 1998 c). The specimens examined from New Caledonia and the Loyalty Islands were collected at the depths of 1– 30 m.Published as part of Osawa, Masayuki, 2007, Porcellanidae (Crustacea: Decapoda: Anomura) from New Caledonia and the Loyalty Islands, pp. 1-49 in Zootaxa 1548 on pages 24-25, DOI: 10.5281/zenodo.17804
