No full textGenus Olssonia n. gen. urn:lsid:zoobank.org:act: 9BB6F0C9-71ED-4F96-BAE8-3BA325B57714 TYPE SPECIES. — Bursa chira Olsson, 1930. DERIVATIO NOMINIS. — Dedicated to the American palaeontologist A. A. Olsson. SPECIES INCLUDED. — Olssonia chira (Olsson, 1930) n. comb., O. yasila (Olsson, 1930) n. comb. DISTRIBUTION. — Olssonia n. gen. is a genus restricted to the Eocene to early Miocene of Peru. DIAGNOSIS. — Shell biconic, dorsoventrally compressed, shortspired, with 7 primary cords on the convex part of the whorl, all but P1 evenly reduced in variceal and intervariceal intervals of each whorl (P1 hardly more expressed than other cords); posterior siphonal canal short; varices strictly aligned; prominent columellar callus. COMPARISONS. — Olssonia n. gen. resembles Marsupina but possesses a lesser number of primary cords on the convex part of the whorl (7 in Olssonia n. gen., 8 in Marsupina). It resembles Aspa but has a much more prominent columellar callus, it is much more granulose, and it has a more sharply defined shoulder and a wider spire angle. Olssonia n. gen. resemble Bufonaria (Fig. 3B), with the same straight anterior siphonal canal, but lacks a spine or blade on the posterior siphonal canal (Fig. 3B; white arrow). REMARKS The representatives of this genus are the oldest confirmed Bursidae; as such they can be used to calibrate the node Bursidae.Published as part of Sanders, Malcolm T., Merle, Didier & Puillandre, Nicolas, 2019, A review of fossil Bursidae and their use for phylogeny calibration, pp. 247-265 in Geodiversitas 41 (5) on page 254, DOI: 10.5252/geodiversitas2019v41a5, http://zenodo.org/record/369993

Aquitanobursa Sanders & Merle & Puillandre 2019, n. gen.
No full textGenus Aquitanobursa n. gen. TYPE SPECIES. — Ranella grateloupi d’Orbigny, 1852. DERIVATIO NOMINIS. — Derived from Aquitaine (Aquitania in Latin), the region where most of the species of the genus occur. SPECIES INCLUDED. — Aquitanobursa grateloupi (d’Orbigny, 1852) n. comb., Aq. amphitrites (Maury, 1917), n. comb., Aq. inaequicrenata (Cossmann & Peyrot, 1924) n. comb., Aq. morrisi (d’Archiac & Haimes, 1853) n. comb., Aq. tuberosa (Grateloup, 1833) n. comb. DIAGNOSIS. — Shell thick, moderately short-spired, varices slightly displaced, 6 primary cords on the convex part of the whorl, variceal and intervariceal P2 very reduced, axial ridges on the first whorl, parietal callus prominent. Posterior siphonal canal short, well-defined; outer lip with weak projection. COMPARISON. — With their deeply marked and angular varices and strongly expressed shoulder, Aquitanobursa n. gen. species resemble some deep-sea species of the Bursa s.l. genus such as Bursa quirihorai Beu, 1987 (Fig. 3H); however, Aquitanobursa n. gen. species are much strongly built, with a thicker shell. Atavistic features displayed by deep-sea gastropods are a well-known phenomenon, described recently for Muricidae by Merle (2012). The phylogenetic relationships of Aquitanobursa n. gen. with other Bursidae remain unclear; this genus is possibly a sister group to all Recent Bursidae, but that in unlikely considering that it occurs at the same time as Aspa marginata and Bursa corrugata. A fair assumption would be that it is the sister group to all bursids except Aspa and B. corrugata, but that would need a phylogenetic analysis for confirmation.

The devil is in the detail: Clinicians, academics and researchers resolving the problems of clinical research
No full text© Australian Academic PressThe difficulties associated with conducting valid family therapy research within a clinical practice discourage many potential researchers. This article will describe collaboration between a group of academics, researchers and clinicians who decided to explore the process and efficacy of systemic family therapy conducted within a working private practice. The specific questions we are addressing are, whether the requests clients bring to their first session of therapy can be reliably classified by practitioners, whether these requests change over time, and whether the nature of the request is associated with therapist and client ratings of therapeutic outcome. Additional questions about the form and nature of the therapeutic alliance as experienced by both client and practitioner are also being explored. This paper will map the passage of the work from inception to its current state where over 140 clients are active participants. In doing so attention will be paid to the obstacles encountered: practical, financial and ethical, and the solutions devised to address these.Catherine M. Sanders, Lisa J. Kettler, Nicole T.

Part A: Detectors for 10.6 Micron Tea CO2 Laser Radiation, Part B: Modulator for Active Mode-Locking
No full textTitle: Part A: Detectors for 10.6 Micron Tea CO2 Laser Radiation, Part B: Modulator for Active Mode-Locking, Author: John W. T. Malcolm, Location: ThodeIn this report various means of infra-red laser radiation detection were investigated. For the measurement of the energy of pulses of 10.6 μm laser radiation for energies up to 15-20 joules and also for energies up to 200 joules, two pyroelectric detector designs were researched. These two detector designs acted as monitors, using 10% of the beam for detection and allowing 90% to be used for other purposes. Responsivities of as much as 120 mV/J for the 15-20 joule detector and 16.7 mV/J for the 200 joule detector were obtained. Also three types of photon drag materials, used for pulse shape analysis and power detection were investigated.
InAs and Te were compared to Ge for a possible faster and more sensitive alternative. Also a means of impedance matching and amplifying the output of these rather low sensitivity detectors using a magnetic current probe was analyzed. Finally an inexpensive and easily constructed container and mount for the 15-20 joules pyroelectric detector was designed along with an attachment to the Lumonics series 100 TEA lasers for ease of alignment with the beam.ThesisMaster of Engineering (ME
Bursa Roding 1798
No full textTACKLING BURSA IN THE FOSSIL RECORD As currently understood, Bursa Röding, 1798 is very morphologically variable, so variable in fact that Beu (1998: 143) gave the broad generic description that “ Bursa is a large genus containing species with short to tall spires, weak to coarse sculpture, heavy and thick to light, thin shells, with varices variable in position […] and with or without a red colour area on the parietal lip”. One conclusion may be that Bursa is a “trash” genus, and exists only to classify species that do not fit anywhere else (this status was confirmed by Castelin et al. 2012 [Fig. 4] and Strong et al. 2018). Being paraphyletic (or polyphyletic), such genera are an impediment for every systematist aiming to describe biodiversity in its historical dimension (Faurby et al. 2016). To our knowledge there are 14 recognized extinct species of Bursidae, two-thirds of them referred to Bursa (Bursa amphitrites Maury, 1917, B. chipolana Schmelz, 1997, Ranella grateloupi d’Orbigny, 1852, Apollon inaequicrenatus Cossmann & Peyrot, 1924, B. sangirana Beu, 2005, R. tuberosa Grateloup, 1833, B. victrix Dall, 1916, R. morrisi d’Archiac & Haime, 1853 and B. landaui Harzhauser, 2009) and the rest to Marsupina Dall, 1904 (Bursa chira Olsson, 1930, Bursa (Marsupina) freya Olsson, 1932, Bursa chira var. yasila Olsson, 1930, Marsupina judensis Beu, 2010, and Gyrineum strongi Jordan, 1936). Following Beu’s (1988, 2010) opinion we consider Marsupina freya, M. judensis and M. strongi to be correctly attributed to the extant genus Marsupina. As we want Bursa to be monophyletic, based on the phylogeny of Castelin et al. (2012) and considering the position of the type species of the genus (B. bufonia (Gmelin, 1791)), we end up with a narrower definition of Bursa; it contains only B. bufonia and B. lamarckii (Deshayes, 1853), to which we can add B. luteostoma (Pease, 1861), B. rosa (Perry, 1811) and B. tuberosissima (Reeve, 1844), on the basis of their tubular and elongated posterior siphonal canal. None of the fossil species mentioned above are closely similar to Bursa bufonia and none of them are type species of a previously published name that could be resurrected. So we are left with two options: either erect new genera (as few as possible) or propose phylogenetic hypotheses linking fossils with extant species (preferably type species). Bursa sangirana Beu, 2005 (Fig. 5E), from the late Pliocene Kalibeng layers (Sangiran, central Java), has a low spire with a warty ornamentation. Its posterior siphonal canal is short; it is very reminiscent of Bursa rhodostoma (G. B. Sowerby II, 1835) (Fig. 3F) and is probably closely related to it. Both species may be included in the separate genus Lampadopsis Jousseaume, 1881 for which B. rhodostoma is the type species. The resurrection of this genus was suggested recently by Strong et al. (2018). Bursa landaui Harzhauser, 2009 (Fig. 4C, D): this slender shell is only known by two external molds from the Aquitanian of Ras Tipuli, Lindi Bay, Tanzania. It has a very fine granulose ornamentation and a weakly expressed shoulder, slightly reminiscent of Bursa granularis (Röding, 1798) (Fig. 3G) and similar to Bursa condita (Fig. 3A). This may be an indication of the close relationship of the three species, for which there are two or possibly three available generic names: Colubrellina Fischer, 1884 and Dulcerana Oyama, 1964. Bufonariella Thiele, 1929 is possibly another available name considering the close resemblance of its type species, Bursa scrobilator (Linnaeus, 1758), to B. granularis. Bursa victrix Dall, 1916: this species is only known from a poorly preserved external mold (USNM 166728) from the late Oligocene of Mascot Point, Flint River, Georgia, United States. The almost evenly inflated whorl profile, with a slightly protruding shoulder angle formed by a row of rounded nodules at approximately the upper third of the whorl height on the spire, the numerous lower rows of nodules extending down over the anterior canal, and the deeply buttressed abapertural face of the varix on the ultimate whorl are all characters in common with Bursa corrugata (Perry, 1811) (Fig. 3D). We follow Beu’s (2010) opinion, keeping it as a species separate from B. corrugata pending the discovery of better-preserved specimens. Among the remaining extinct bursid species, two are strikingly similar: Marsupina chira (Olsson, 1930) and M. yasila (Olsson, 1930), for which we propose a new genus, Olssonia n. gen. In the same fashion, Bursa amphitrites Maury, 1917, B. grateloupi (d’Orbigny, 1842), B. inaequicrenata (Coss- mann & Peyrot, 1923), B. tuberosa (Grateloup, 1833), Bursa chipolana Schmelz, 1997, and Ranella morrisi d’Archiac & Haime, 1853 are here attributed to a new genus: Aquitanobursa n. gen.
