Prame Chopra - geophysician and earth scientist
No full textThis interview with Prame Chopra, previously a member of the Geology Department in the Faculties, is part of the ANU Emeritus Faculty's Oral History Program, involving retired staff members who were part of the university in its earlier life. The Oral History Program was initiated and developed by ANU Emeritus Faculty as a contribution to university and community understanding of the beginnings and development of ANU over the past six decades. Emeritus Faculty has a special interest in this period, since the Faculty's membership includes many of the people who helped shape the university in its early days, to make it the pre-eminent institution it is today. This interview with Fyfe Bryant was recorded in January 2016.
Prame Chopra was born in Melbourne in 1953 and was educated at schools in Melbourne, Adelaide and Newcastle. Immediately prior to Prame’s introduction to ANU he was an Honours student at the University of Newcastle. He came to Canberra in the winter of 1975 as one of a group of fourth year geology students invited from other Australian universities to the Research School of Earth Sciences. This was the first attempt by the School to foster better links with prospective PhD candidates from Australia.
Consequently Prame enrolled in the PhD program at RSES from 1976 to 1980. He worked in the high pressure/ high temperature laboratory of Professor Mervyn Paterson on the rheology of olivine rocks to better determine the flow properties of these rocks. This enabled modelling of the processes that drive Plate Tectonics/ Continental Drift. Prame said “I have very fond memories of my time at ANU as a postgraduate student”

Physopelta (Neophysopelta) confusa Zamal & Chopra 1990
No full textPhysopelta (Neophysopelta) confusa Zamal & Chopra, 1990 Physopelta confusus [sic!] Zamal & Chopra, 1990: 7, 11–12 (description, figures, distribution). HOLOTYPE: ♂, India, Jharkhand, Hundru, Ranchi (deposited either in Department of Entomology, Haryana Agricultural University, Hisar, or Assam Agricultural University, Jorhat). Original description (adopted from ZAMAL & CHOPRA 1990): ‘General colouration fusco-testaceous; head, tylus, juga and antenniferous tubercle dull reddish-brown; bucculae dark-brown; eyes, antennae and labium fuscous. Pronotum dark reddish-brown; thoracic pleura fuscous with posterior margins blackish; area near bases of coxae lighter in colour; metathoracic scent gland lobes dull sanguineous; scutellum dark-brown; hemelytra fusco-testaceous with a small round spot near middle and a very small spot outer to it fuscous to black; membrane fuscous. Abdominal intersternal sutures dark with curved lateral fuscous depressions. Body oblong; head pubescent and impunctate, head length: 1.50–1.60; tylus declivent; eyes comparatively large almost touching antero-lateral pronotal margins; width across eyes: 2.10–1.30 [sic!]; interocular distance: 1.10–1.30; antenniferous tubercle small; antenna medium sized, length antennal segments: I, 1.80–2.00; II, 1.50–2.10; III, 1.40–1.50; IV, 1.80–1.90; labium extending to hind coxae; labial segment I not reaching base of head; length labial segments: I, 1.30–1.40; II, 1.20–1.40; III, 1.20–1.30; IV, 1.20–1.40. Pronotum pubescent; anterior pronotal convexity prominent both in males and females, but more so in males; anterior pronotal lobe comparatively small and impunctate; posterior lobe punctate, lateral pronotal margins carinate, moderately sinuate at middle but out reflexed; length pronotum: 2.60–3.10; width: 4.20–4.40; scutellum triangular, pubescent and punctate; somewhat transverselly impressed anteriorly; scutellar length: 1.90–2.00; width: 2.20–2.30; fore coxae with a small blunt spine like protuberance; fore femora slightly incrassate with thick spines beneath throughouts in males but with only a few spines at apex in females; hemelytra extending to tip of abdomen. Abdominal length: 9.60–10.20. Male pygophore with a small, hairy and distally rounded median lobe: median projection apically separate; clasper with a large lobe at middle having two long hairs; spermatheca with spherical bulb, short pump and duct; flange absent. Total length: 14.10–14.50. Physopelta confusa sp. nov. is apparently similar to Ph. gutta but can be easily distinguished by its colouration, presence of an additional spot on hemelytra and characteristic male genitalia and female spermatheca.’ Distribution. India (Jharkhand) (ZAMAL & CHOPRA 1990). Note. When describing Physopelta trimaculata (STEHLÍK & JINDRA 2008a) I was not aware of the description of Ph. confusa. Comparing the types of Ph. trimaculata with the original description of Ph. confusa by ZAMAL & CHOPRA (1990), the two species are very similar, sharing the the presence of two black spots in the middle of the corium, a larger inner one and a smaller outer one. Physopelta confusa apparently differs in the absence of the black spot in the posterior angle of the corium, a feature not mentioned by ZAMAL & CHOPRA (1990), and the general body colouration (fusco-testaceous in Ph. confusa, reddish in Ph. trimaculata). Body length of Ph. confusa is 14.1–14.5 mm (ZAMAL & CHOPRA 1990) which is within the variation of Ph. trimaculata (13.2– 15.7 mm) (STEHLÍK & JINDRA 2008a). Without examination of the type material of Ph. confusa it is not possible to decide whether the two species represent only colour varieties of a single species, or represent two distinct species.Published as part of Stehlík, Jaroslav L., 2013, Review and reclassification of the Old World genus Physopelta (Hemiptera: Heteroptera: Largidae), pp. 505-584 in Acta Entomologica Musei Nationalis Pragae 53 (2) on pages 524-525, DOI: 10.5281/zenodo.573995
Antibacterial spectra of drugs used for chemotherapy of mycobacterial infections
No full textThe mechanism of action of many antimycobacterial agents is poorly understood. To
obtain preliminary information on whether the targets for some of these drugs
might also occur in other bacteria, the in vitro activities of selected agents
against Escherichia coli, Bacillus subtilis and Staphylococcus aureus were
determined. Dapsone, p-aminosalicylic acid and thiacetazone failed to inhibit the
above organisms (MIC values > 100 micrograms/ml) that may therefore lack targets
for these drugs. Capreomycin, viomycin and clofazimine demonstrated activity
against some of the organisms (MIC values < 100 micrograms/ml) suggesting that
the targets of these drugs may not be restricted to mycobacterial species. The
agents were all potent inhibitors of Mycobacterium bovis bacille Calmette-Guéri
Stegoalpheon Chopra 1923
No full text<i>Stegoalpheon</i> Chopra, 1923 <p>DIAGNOSIS (modified from Markham, 1977): Female: body ovate, wider than long, slightly asymmetrical; head separated from pereon, large frontal lamina. Pereomeres distinct, all except first subequal in length, first shorter, sixth segment not shorter than others, coxal plates on segments 1–4; dorsolateral bosses indistinct, marsupium open. Oostegite 1with prominent posterolateral falcate points extending far beyond sides. Pleomere of 6 segments, distinct dorsally and laterally; segments 1–5 (sometimes 6) with dorsally directed lateral plates and biramous pleopods ventrally located and extending to sides of pleon. Uropods uniramous, similar to pleopods in shape.</p> <p>Male: Head distinct from pereon, eyes large. Pereomeres well defined. Pleon with all segments fused, pleopods and uropods absent.</p> <p> TYPE SPECIES: <i>Stegoalpheon kempi</i> Chopra, 1923, by original designation.</p> <p>OTHER SPECIES: None.</p> <p> REMARKS: Chopra (1923) originally de‐ scribed <i>Stegoalpheon kempi</i> as having five pairs of triramous pleopods However, Shiino (1951) and Pillai (1966) convincingly showed that the dorsally directed lobes were lateral plates and that the pleopods were biramous. Markham (1977) stated that the type species has five pairs of uniramous lateral plates and five pairs of uniramous pleopods, but this is incorrect. There is clearly some variability in the number of lateral plates, as Chopra (1923) indicated five pairs, which argrees with the present material, while both Shiino (1951) and Pillai (1966) described specimens with six pairs.</p> <p> <i>Stegoalpheon kempi</i> Chopra, 1923 Figure 3</p> <p> <i>Stegoalpheon kempi</i> Chopra, 1923: 462, 464– 467, text fig. 8, pl. 13, fig. 1–7 [India, infesting <i>Alpheus</i> cf. <i>lobidens</i> (De Haan, 1849)]; Shiino, 1951: 26–29, figs. 1–2 [Japan, infesting <i>Alpheus rapax</i> Fabricius, 1798]; Pillai, 1954: 20; Pillai, 1966: 188– 190, figs. 12–20 [India, infesting <i>Alpheus</i> sp.]; Shiino, 1958: 61 [Japan, infesting <i>Alpheus rapax</i> Fabricius, 1798]; Rao and Ramaprasad, 1964: 588–589, figs. 1–2 [India, infesting <i>Alpheus malabaricus</i> (Fabricius, 1775)]; Shiino, 1972: 8; Kannupandi, 1976: 87–93, figs. 1–3; Markham, 1977: 109–111, 119–120; Adkison et al., 1982: 337; Kensley, 2001: 226; An, 2006: 65–65, fig. 27; An et al., 2008: 225–226, fig. 2 [China, infesting <i>Alpheus</i> sp.]; Liu, 2008: 693; Williams and Boyko, 2010: 150; An, 2011: 134–136, figs. 5-5–5-7 [same material as An et al., 2008].</p> <p> <i>Stegoalpheon choprai</i> Pillai, 1954: 20 [India, infesting <i>Alpheus paludicola</i> Kemp, 1915]; Rao and Ramaprasad, 1964: 588; Markham, 1977: 109, 111, 120; Kensley, 2001: 226; Williams and Boyko, 2010: 150.</p> <p> <i>Stegoalpheen</i> [sic] <i>kempi</i> — Rao and Ramaprasad, 1964: 588 (figure caption).</p> <p> MATERIAL EXAMINED: Infesting <i>Alpheus</i> sp., 1 ♀, 1 ♂ (CIEAL880701), Niuchelun Jiao of Nansha, 116 <b>°</b> 10′E, 9 <b>°</b> 36′N, 23 July 1988; 1 ♀, 1 ♂ (CIEAL940901), Banyue Jiao of Nansha, 116 <b>°</b> 16′E, 8 <b>°</b> 52′N, 29 September 1994.</p> <p>DESCRIPTION: Female (CIEAL880701): Length 4.28 mm, maximal width across pereomere 3 4.43 mm, head length 0.88 mm, head width 1.29 mm, almost symmetrical (fig. 3A, B).</p> <p>Body oval, length 3/4 width. All segments distinct. Head pentagonal, frontal lamina obscure, but anterior margin of the head extended (fig. 3A). Black eyes on lateral corner of anterior margin of head. Antennule of three articles, antennae of four articles, terminally setose (fig. 3C). Maxilliped (fig. 3D) without palp, but tuft of setae indicating palp location. Plectron extend and sharp. Barbula (fig. 3E) with two pairs of falcate lateral projections on each side, one median small tubercle present.</p> <p>Pereon broadest across third pereomere (fig. 3A). Coxal plates reduced, dorsolateral bosses on first five pereomeres. Tergal projections of pereomeres 2–4 distinct. Brood pouch completely open (fig. 3B). Oostegite 1 with smooth internal ridge, posterolateral point rounded laterally (fig. 3F, G). Pereopods short, with blunt dactyli (fig. 3H). Pleon of six pleomeres, first five pleomeres with small, dorsally directed, tubercular lateral plates. Five pairs of biramous ovate pleopods, those on longer side of body much larger than those on shorter side (fig. 3B). Sixth pleomeres with uniramous uropods, similar in shape to pleopods.</p> <p>DESCRIPTION: Male (CIEAL880701): Length 2.03 mm, maximal width (across pereomere 4) 0.95 mm, head width 0.52 mm, head length 0.34 mm, pleonal length 0.35 mm (fig. 3I, J). Head pentagonal, separated from first pereomere (fig. 3I). Irregular black eyes near postolateral corner of the head (fig. 3I). Antennule of three articles, antenna of seven articles, much longer than antennule, antennulae and antenna terminally setose (fig. 3K). Pereon much wider than head, segements distinct (fig. 3I), all subequal in width. Pereomeres 6 and 7 with midventral projections (fig. 3J). First four pereopods larger than last three, dactyli of first two larger than others (fig. 3J). Pleon fused into single piece, without any pleopods or uropods (fig. 3J).</p> <p> HOSTS AND LOCALITIES: Infesting <i>Alpheus</i> cf. <i>lobidens</i> (De Haan, 1849), <i>Alpheus malabaricus</i> (Fabricius, 1775), <i>Alpheus paludicola</i> Kemp, 1915, <i>Alpheus rapax</i> (Fabricius, 1798), <i>Alpheus</i> sp. (Alpheidae), India, Japan, China.</p> <p> REMARKS: As pointed out by Williams and Boyko (2010), <i>Stegoalpheon choprai</i> was synonymized with <i>S</i>. <i>kempi</i> by Pillai (1966), despite later (Markham, 1977; Kensley, 2001) citations of the species as valid. The present females conform well with Chopra’ s (1923) holotype although with much smaller dorsally directed lateral plates; however, the present male possesses midventral projections on the last two pereomeres and a wider pereon (allotype male without any midventral projections and a pereon subequal in width compared to the head).</p> <p>Pseudioninae Codreanu, 1967</p> <p>DIAGNOSIS: Female: All body segments dis‐ tinct, head usually fused with frontal lamina. Pereon with coxal plates, dorsolateral bosses, and tergal projections. Pleopods usually biramous, uropods present.</p> <p>Male: Head separated from first pereomere, or fused on posterior edge. All pereomeres distinct, often with midventral tubercles. Pleon with one (fused) or six distinct pleomeres, usually with tubercular or flaplike pleopods on first five pleomeres. Uropods sometimes present.</p> <p>REMARKS: Pseudioninae is largest and most heterogeneous subfamily in Bopyridae, in‐ cludes 48 genera and 236 species, and may not be monophyletic (Williams and Boyko, 2012). Some species possess putatively primitive characters, such as males having lateral plates on the pleon and well-developed pleopods. All species are branchial parasites and most species infest anomurans, axiideans, and gebiideans, with relatively few being found on carideans and brachyurans.</p>Published as part of <i>An, Jianmei, Boyko, Christopher B. & Li, Xinzheng, 2015, A Review Of Bopyrids (Crustacea: Isopoda: Bopyridae) Parasitic On Caridean Shrimps (Crustacea: Decapoda: Caridea) From China, pp. 1-85 in Bulletin of the American Museum of Natural History 2015 (399)</i> on pages 20-23, DOI: 10.1206/amnb-921-00-01.1, <a href="http://zenodo.org/record/4612506">http://zenodo.org/record/4612506</a>
