Pollicipes fimbriata Withers 1912
No full textPycnolepas fimbriata (Withers, 1912) Original description. Withers (1912: 506, pl. 23, fig. 1 a, b, as Brachylepas (?) fimbriatus) [see also Withers 1928: 91, pl. 12, figs 9–12]. Type. Holotype is a carina in the M. Remeš Collection (Olomouc), an ‘electrotype’ of which is NHM I. 15818. Locality and stratigraphy. Stramberg (= Štramberk), Moravia (Czech Republic); Red Limestone, Tithonian (141 – 135 Ma). Remarks. The single carina known of P. fimbriata is semicylindrical, strongly convex transversely, noncarinate and comparatively small (length c. 13 mm), with a near-straight basal margin; ornament consists of regularly spaced, prominent, transverse and rounded longitudinal ridges. Two other capitular valves have been referred to this species, albeit with a query. One is a fragmentary tergum (Withers, 1928: pl. 12, fig. 11; Red Limestone, Nesselsdorf = Koprivnice), with a straight apicobasal ridge; the other a fragmentary?rostrum (Withers, 1928: pl. 12, fig. 12). In the absence of other valves, assignment to Pycnolepas must remain tentative; Withers (1928: 93) noted a general resemblance to the carina of P. rigida. Occurrence. Known only from the Red Limestone (Tithonian) of Štramberk and Koprivnice, Moravia (Czech Republic); no subsequent records.Published as part of Jagt, John W. M., Zonova, Tatiana D. & Jagt-Yazykova, Elena A., 2007, A review of the brachylepadomorph cirripede genus Pycnolepas, including the first record of an Early Cretaceous species from the Russian Far East *, pp. 33-47 in Zootaxa 1545 on pages 35-36, DOI: 10.5281/zenodo.17797
Eigenstrain modelling of residual stress generated by arrays of Laser Shock Peeing shots and determination of the complete stress field using limited strain measurements
No full textThis paper presents a hybrid explicit finite element (FE) /eigenstrain model for predicting the residual stress generated by arrays of adjacent/overlapping laser shock peening (LSP) shots where the use of a completely explicit FE analysis may be impractical. It shows that for a given material, the underlying eigenstrain distribution (in contrast to the resulting stress field) representing a laser shock peen is primarily dependent on the parameters of the laser pulse and the number of overlays rather than the precise component geometry. Consequently the residual stress introduced by complex laser peening treatments can be built up by using static FE models and superposition of individual eigenstrain distributions without recourse to further computationally demanding explicit FE analyses. It is found that beneath a small patch of LSP array the magnitude of the compressive residual stress is higher than for a wider array of LSP shots and that with increasing numbers of layers the compressive stress increases as does the depth of the compressive zone. The model predictions for the eigenstrain distributions are compared well with experimental measurements of plastic strain (full-width-at-half-maximum) obtained by neutron diffraction. The eigenstrain method is also extended to construct the full residual stress field using measured residual elastic strains at a finite number of measurement locations in a component.<br/

Pollicipes bruennichi Withers 1914
No full textPycnolepas bruennichi Withers, 1914 Original description. Withers (1914: 181, pl. 7, figs 5–9; pl. 8, fig. 6, as Pycnolepas brünnichi). Type. Holotype is NHM I. 16625, a right scutum. Locality and stratigraphy. Fakse, Sjaelland (eastern Denmark); middle Danian (Tylocidaris bruennichi Zone; c. 63 Ma). Remarks. Valves of this species are strongly ridged both transversely and longitudinally; scutum subtriangular, with broad wall-sided apicobasal ridge, occasionally broader than tergo-lateral portion, tergum with apical portion only slightly curved towards scutum and a similar, yet much narrower, near-straight apicobasal ridge. Height of imbricating plates exceeding width. On tergum, longitudinal ridges subdued by prominent growth lines. Thousands of isolated, yet associated, valves are known from the middle Danian of Fakse, and allow the species to be reconstructed; however, upper latera invariably are rare. Postulated to have been attached either to certain scleractinian corals and/or logs (Donovan & Jakobsen, 2004), substrates now dissolved. Withers (1914) proposed Pycnolepas bruennichi as a replacement name for Pollicipes elegans Darwin, 1851 (76, pl. 4, fig. 9 a–d), non Lesson (1830: 441), and later (Withers, 1935) showed P. bruennichi to be confined to strata of early Paleocene (Danian) age. Drygant (1966: 116, fig. 8 a, b) recorded a single carina from upper Maastrichtian levels at Briukhovichi, Volhynia-Podolia (now western Ukraine) which he assigned to Pycnolepas elegans (Darwin). This, however, clearly represents a typical carina of the calanticine Scillaelepas darwiniana (Bosquet, 1854), as already noted by Alekseev (1979). Occurrence. Lower and middle Danian of Denmark (Withers, 1914, 1935; Jakobsen, 2003; Donovan & Jakobsen, 2004; Jakobsen & Feldmann, 2004), southern Sweden (Limhamn area), northeast Belgium and the southeast Netherlands (Jagt & Collins, 1988; Jagt, 1996) and the Crimean Peninsula, Ukraine (Alekseev, 1979).Published as part of Jagt, John W.

Description: Head with an eyebridge of 3 facet rows; distance between eyes 4 facet diameters; several postocular bristles behind eyes. Antenna with scape, pedicel and 14 flagellomeres: absolute length 0.038-0.05-0.042-0.044- 0.042-0.042-0.044-0.044-0.046-0.046-0.036-0.036-0.03-0.022- 0.02-0.044 mm; relative length 19-25-21-22-21-21- 22-22-23-23- 18-18-15-11 -10-12. Flagellomeres 5–11 with a pair of digitiform curved ascoids. Palpus segments, absolute length: 0.05-0.062- 0.074-0.138 mm; relative lenght 25-31-37-69. Wing 2.70 times longer than wide; length 1.82 mm, width 0.67 mm. Male terminalia (Fig. 16) with hypandrium expanded along 1/3 of its ventral length with 2 lateral and 1 median widenings. Gonocoxite approximately 2x longer than its median width; inner side with a basal group of setae, just before middle 2 long setae; gonostylus longer than gonocoxite, almost straight. Parameres with a broad ventral bridge, lobes just reach the bases of the long setae on gonocoxite, ventrally in the midst with a racket-shaped brownish spot of aedeagus sheath; above a pair of processes as long as the more ventral processes that do not meet in the middle. Further dorsal large basally round condyles with parallel inner edges form the keel. Basiphallus longer than wide, basally broader, apically bilobed; ventral lobe bifid, ventral part connected to the distiphallus, longer part slightly bent with blunt tip; distiphallus longer than gonocoxites angular, with both ends acute, the broader end with a broad projection, the smaller end double-headed. The end of the dorsal distiphallus is across anchor-shaped sclerite clearly thinner than the its ventral counterpart. Epandrium rhomboid, epandrial processes almost straight, apically with 8 feathered tenacula. Distribution: Greece, island of Ikaria. Etymology: The epithet is derived from the island of Ikaria, where the species was collected. Remarks: Another species of the T. sieberti -group. The middle part of the hypandrium is less prominent than in T. turcica and T. sieberti. The shape of the hypandrium, and the long and angular distiphallus distinguish the new species from its congeners.Published as part of Wagner, Rüdiger & Withers, Phil, 2020, The West-Palearctic species of the genus Tonnoiriella Vaillant, 1971 (Diptera: Psychodidae, Psychodinae), pp. 183-210 in Zootaxa 4728 (2) on page 194, DOI: 10.11646/zootaxa.4728.2.2, http://zenodo.org/record/362111
