UK Rules For Unfired Pressure Vessels
No full textThe present code PD 5500, formerly BS 5500 [1] evolved partly from the well-known BS 1500 [2] in the 1950's and BS 1515 [3] first published in 1965; the latter permitted higher level allowable stresses and more advanced rules. In 1969, following a report from the Committee of Enquiry into the Pressure Vessel Industry, the British Standards Institution brought all the pressure vessel interests together under one general committee in order to rationalise the activity. This became PVE/ and presides over a large committee structure. There are a series of functional sub-committees who deal with specific aspects and a large number of technical committees as well as many additional sub committees and working groups. Most of these meet regularly. The technical committee PVE/1, Pressure Vessels, has overall responsibility for BS 5500. The functional committee PVE/1/15 Design Methods has an overall responsibility relating to 'Design' with particular reference to the design section of BS 5500 (Section 3). The first edition of BS 5500 was issued in 1976. The actual issue was delayed for some time because, in the early 1970's, there was an attempt in Europe to produce an international pressure vessel standard. A draft of the international standard appeared as ISO DIS 2694 [4] in 1973 but it was not generally accepted and the attempt was abandoned in the mid 70's. It was decided to use some of the material from 2694 within BS 5500 so that although the Standard was long delayed it benefited to some extent from the international efforts. Initially, committee PVE/l set out the concept of a "master" pressure vessel standard which could readily be applied to any vessel in either ferrous or non-ferrous materials and for highly specialised application with the minimum of supplementary requirements. The layout of BS 5500 is consistent with this concept and although the Standard has perhaps not fulfilled this high ideal, it has certainly been employed widely in many industries including non pressure vessel type applications. When issued it had a number of distinctive features compared with other pressure codes viz; weld joint factors were removed, the present three categories of construction were introduced, there was a new novel external pressure section, it has a loose leaf format and an annual updating was introduced. Further editions of BS 5500 have been issued every three years since 1982

ROTATIONAL STRUCTURE OF THE BAND OF

Spectroscopy 7, 223 (1961).Author Institution: Department of Chemistry, University of CaliforniaThe vibrational structure of the band of XeO has been reported by . In the present work the rotational structure of the 0--4, 1--5, and 0--5 vibronic transitions in the band of XeO have been resolved. Spectra were taken of an air-xenon mixture at 0.24 torr using 3.5 Mc excitation. Less than 0.1% air was present. Preliminary analysis of the data gives the following rotational constants: B_{o}{^{\prime}}1=0.09 \pm 0.02 cm^{-1}, B_{2}{^{1}}=0.06 \pm 0.01 cm^{-1}, B_{4}""}=0.39 \pm 0.02 cm^{-1}, B_{5}""}=0.31 \pm 0.03 cm^{-1}
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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

5500: performance, control, and politics
No full textIn the period between June 2014 and June 2015, at least 5,500 immigrants died trying to reach Europe from Africa while crossing the Mediterranean Sea. In this paper we present 5500, a piano performance that is a part of an on-going project that investigates the incorporation of electrical muscle stimulation (EMS) into musical performances, with a particular interest in the political significance of the negotiation of control that arises. 5500 consists of a performance of Beethoven's Sonata Path\'{e}tique, where the pianist's execution is disrupted using computer-controlled electrodes which stimulate the muscles in his or her arms causing their involuntary contractions and affecting the final musical result
Variations on the Author
Get PDF“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
