Transcript of interview with William C. Watson Jr., Deputy Director of CDC and Joseph F. Giordano, PHA conducted by Donald A. Berreth September 15, 1984
No full textTranscript of interview with William C. Watson Jr., Deputy Director of CDC and Joseph F. Giordano, PHA conducted by Donald A. Berreth September 15, 1984.Summary: Watson and Giordano began describing how they were recruited to the public health service. Watson was hired to the Venereal Disease (VD) program by Johannes Stuart and soon became Giordano\u2019s boss in the Public Health Service (PHS). The VD program in the South East focused on running mass blood tests for syphilis, which they said was easier to do then than it would be now. They both recalled the work environment after WWII: people were eager workers and jobs were found easily, but the high job loss rate meant people had to be flexible, mobile, and hard working. Finally, Watson described the power struggle with former CDC employees when the VD program had to move to Atlanta; the VD team brought a grant program, regional office structure, field staff, and big budget. Despite faults of the times, Watson praised the PHS as a well-managed organization
An experimental study on trailing edge crack detection for wind turbine blade using airfoil aerodynamic noise
No full textRecent decades have witnessed more and more wind turbines (WTs) being installed onshore and offshore. Health condition monitoring for WTs structures and components is increasingly becoming a compelling concern for stable power output and operational safety of a wind farm [1]. Blade damages seem to occur with a higher probability ahead of other components (e.g., gearbox and generator) damages [2]. After reviewing traditional damage detection approaches and their limitations [3], in this research a new non-contactable approach to detecting trailing edge (TE) damages is proposed based on airfoil aerodynamic noise measurements using a microphone array. In the experiment, four changeable TE parts with rectangular cracks (damaged width W of 0.2mm, 0.5mm, 1.0mm and 2.0mm) for a NACA0018 airfoil (chord C=200mm, span L=400mm) are designed and an example with W=0.2mm is shown in Fig.(a). The TEs with cracks have the same solid thickness as the baseline one (h_solid=0.76mm, standard NACA0018 airfoil TE thickness with chord of 200mm) but different dimensions of total TE thickness (h=W+h_solid). A phased microphone array with 64 microphones is used for acoustic measurement then beamforming is applied to extract TE noise and source power integration is performed within a 200×200mm2 region centred at TE midpoint [4][5]. Fig.(b) shows sound pressure levels (SPLs) L_p at the integrated region of four damaged cases as well as baseline with the frequency resolution of 10Hz under the freestream velocity U of 35m/s and geometrical angle of attack (AoA) alpha of 0º. The cases with smaller cracks show less remarkable tonal peaks compared with the one of W=2.0mm (~4dB); when the crack size is smaller the spectral peak broadens. These peaks or humps are attributed to the periodic vortex shedding from blunt TEs. Fig.(c) shows the SPL differences Delta L_p between the damaged cases and baseline; frequency is normalized as TE-thickness-based Strouhal number St. Local maxima of Lp are present at approximately St = 0.1 [6]. In the experiment, it is difficult to extract the spectral peaks or humps if the effective AoA (alpha*) [6] is more than 2.40º because the boundary layer on suction side becomes thicker and the asymmetry of boundary layers prevents coherent and periodic vortex shedding [7]. In Fig.(d), the discrete points are the St at peak L_p (St_peak) versus the ratio of TE thickness and averaged displacement thickness of pressure and suction sides (overline delta *) extracted from available cases (U=15m/s, 20m/s, 25m/s, 30m/s and 35m/s); the grey and blue curves are obtained from models reported in [6] with solid angle (Psi) of 20º and 23.76º (baseline solid angle), respectively. The points of St_peak versus thickness ratio show a good agreement with the prediction model [6]. This means that particularly for smaller cracks at the first stage of damaged process, the effect of solid angle can be neglected and considered as a minor and adjunctive factor. The TE thickness retrieved through the application of the model can be used as a prediction of the damage level. Additional data obtained from experiments with turbulent inflow will be presented to assess if the approach proposed is still feasible in more realistic turbulent inflow conditions.

Filellum conopeum Watson 2003
No full textFilellum conopeum Watson, 2003 Filellum conopeum Watson, 2003: 159 –160, figs. 9 a–c. Type series. Holotype— Filellum conopeum Watson, 2003, malinol-mounted microslide, sparse fertile colony on stem of Acryptolaria patagonica (NMV F 91342) (Watson 2003: 159). Type locality. From the holotype, off Macquarie Island (53 ˚ 55.8´S– 53 ˚ 55.7´S; 159 ˚ 5.5´E– 159 ˚ 4.7´E), 453 m, (Watson 2003). Description. See Watson (2003: 159–160). Distribution. Filellum conopeum is known only from its original description, off Macquarie Island (53 ˚ 55.8´– 53 ˚ 55.7´S; 159 ˚ 5.5´– 159 ˚ 4.7´E) (Watson 2003). Remarks. Filellum conopeum was described by Watson (2003: 159) as bearing “Hydrothecae stolonal […]. Proximal quarter to one third of hydrotheca adnate to stolon, dorsal abcauline wall furrowed by many close, sharpedged ridges with minute ragged frill of perisarc; ridges fading on adnate wall. Adnate wall becoming free at a sharp upward bend, free part cylindrical or weakly expanding from bend to margin, free part straight to broadly curved, walls smooth, occasionally with several regenerations. Margin circular, transverse, with smooth, distinctly everted rim. Perisarc of walls fairly thick, thinning distally. Hydranth with c. 12 tentacles and clavate hypostome”. Trophosome features of F. conopeum are found in other species of the genus, such as F. serratum, F. a n t a rc t i c u m or F. magnificum, so they alone do not allow a proper identification of the species, although F. mangnificum differs from Watson’s species by the distinctly larger hydrothecae, particularly in relation to the diameter of the hydrothecal aperture. As with other species of the genus, truly diagnostic characters of F. conopeum are based on features of the coppiniae: “Coppinia bud-shaped, c. 1 mm wide and 1 mm high, comprising many tightly packed gonothecae enclosed within a cone of protective nematophorous tubules. Gonotheca flask-shaped (lateral view), base rounded, body expanding a little from base to shoulder then narrowing into a short straight or slightly curved neck tapering to a circular aperture; in transverse view gonothecae polygonal. Nematophorous tubules similar in length, not forked, conjoined just above gonothecae then becoming free, most narrowing distally and inwardly curved to meet above gonotheca; terminal orifice circular. Perisarc of gonothecae and tubes moderately thick; perisarc of tubes somewhat roughened. Planulae enclosed in gonothecae small, spherical.” (Watson 2003: 160). The general structure of the coppinia of this species resembles that of F. a n t a rc t i c u m and F. magnificum, in which the defensive tubes are situated on the periphery of the mass of gonothecae, like a fence, arching over the gonothecae (in F. magnificum the defensive tubes also arise among the gonothecae). They are different, however, because the gonothecae lack a distal neck in F. antarcticum, and have a short, clearly differentiated distal neck with an everted rim in F. magnificum. In Watson’s species, however, the “body expanding a little from base to shoulder then narrowing into a short straight or slightly curved neck tapering to a circular aperture”. Although Watson did not give measurements of the gonothecal neck, this seems distinctly longer in general and variable in shape. The cnidome of F. conopeum is unknown and, therefore, no comparison concerning this character can be made.Published as part of Marques, Antonio C., Peña, Álvaro L., Miranda, Thaís P. & Migotto, Alvaro E., 2011, Revision of the genus Filellum Hincks, 1868 (Lafoeidae, Leptothecata, Hydrozoa), pp. 1-28 in Zootaxa 3129 on pages 11-12, DOI: 10.5281/zenodo.20678
