R/V VITYAZ- 2, Atlantic Ocean: St. 79, 34° 54.3 ’N, 45 ° 39 ’W, 4440 m (1 tube studied with SEM, PIN 5485 / 14 and X-ray diffraction analysis, sample # 2). Description. Tube: white, opaque, ostensibly free, with shiny surface, open at both ends, straight or slightly curved, slowly increasing in diameter, slightly twisted spirally (Fig. 8 C, D, H, I). Cross-section tetragonal (Fig. 8 J). Sides of tube slightly concave, but cross-section becomes almost circular anteriorly (Fig. 8 J). Some tubes showing growth stops marked by tiny constrictions, not peristomes, accompanied by sudden turns around growth axis up to 45 ° (Fig. 8 C, D), some tubes can be slightly twisted (Fig. 8 H, I). Wall thickness varying between tube sides, with one side (lateral?) being significantly thinner (Fig. 9 F), making tube cross-section bilaterally symmetrical (see Size as well). Tube ultrastructure: wall unilayered, with irregularly oriented prismatic (IOP) structure consisting mostly of elongated cigar-shaped crystals, but appearance and orientation of crystals throughout the wall not uniform. Inner part thin (1 / 10 – 1 / 15 of wall, Fig. 9 D), but clearly distinct; consisting of consolidated rice grain-shaped crystals oriented more or less along growth direction by their axes. Length of crystals about 3–4 µm, diameter 0.5 µm. Middle wall part separated from inner layer by characteristic zone with numerous elongated “cavities”, positioned along growth lamellae of tube wall (Fig. 9 A, D, E). These cavities entirely surrounding lumen also visible in transverse sections (Fig. 9 G, J). Middle part of tube wall (Fig. 9 C, I) consisting of unoriented crystals similar in shape and size to crystals of inner and outer parts. Outer wall part (Fig. 9 B, H) composed of elongated crystals similar to crystals of inner layer, also oriented loosely parallel to tube wall. All variations of wall thickness produced by middle and outer wall parts (Fig. 9 G), thickness of inner part and “cavities” zone being stable. Parabolic growth lamellae indistinct, but visible (Fig. 9 A, C) in sections. Tube mineralogy: sample # 1: 20 % calcite (I calc= 9), 80 % aragonite (I arag= 37); sample # 2: 55 % calcite (I calc= 56) and 45 % aragonite (I arag= 44). Radiolar crown: 4–6 pairs of radioles arranged in semicircles to pectinately, not joined by inter-radiolar membrane. Radiolar eyes not visible in preserved material. Long naked tips of radioles absent. Peduncle: inserted slightly in front between 1 st and 2 nd dorsal radioles, about same thickness as radioles, smooth (no pinnules), slightly longer than radioles (Fig. 8 E). Operculum: elongated, covered with convex yellow-brown chitinous cap, sometime with a knob in the centre (Fig. 8 A, E); opercular bulb gradually narrowing towards peduncle, but separated by shallow conspicuous constriction. Collar and thoracic membranes: collar short, subdivided into 2 latero-dorsal and 1 ventral lobe, the latter slightly incised. Thoracic membranes reaching up to 2 nd chaetiger, about same width throughout. Thorax: with 7 thoracic chaetigers, 6 of which uncinigerous (Fig. 8 B, F, G). Tori widely separated, first and second slightly closer to each other. Thoracic tori of similar size along thorax. Collar chaetae as few short capillaries (Fig. 10 B); other thoracic chaetae limbate, with short slightly bent distal blades; Apomatus chaetae present (Fig. 10 C). Uncini saw-shaped with 9–11 teeth in profile view, dental formula P: 1: 1: 1: 1: 1: 1: 1: 1: 1 (Fig. 10 D); anterior peg pointed. Abdomen: with up to 45 segments. Uncini similar to thoracic ones, but rasp-shaped, with 3–4 rows, dental formula P: 3: 3: 4: 4: 4: 4: 3: 3: 3 (Fig. 10 F). Chaetae flat triangular blade with rounded denticles, only slightly longer on posterior segments (Fig. 10 K); each chaetiger usually with a single chaeta. No achaetigerous zone between thorax and abdomen. Posterior glandular pad absent. Size: total body length up to 15 mm, including up to 11 mm long radioles, width of thorax up to 0.4 mm. Maximum tube fragment length observed 35 mm (tubes incomplete). External tube diameter up to 0.67 mm with corresponding lumen diameter up to 0.45 mm. Thickness of tube wall in between angular margins about 1 / 7 th of outer diameter at thinner sides, and ~ 1 / 6 th at thicker sides. Distribution. North Atlantic, low bathyal to abyssal depths (1732–4823 m), Indian Ocean (Amsterdam Island), 2200 m, Pacific Ocean, 3315–6127 m. Etymology. The species is named after Professor Greg Rouse (Scripps Institution of Oceanography, USA) who made important contributions to serpulid phylogeny and deep-sea biology. Remarks. This species apparently was first characterised by Fauvel (1909, 1914) from empty tubes only: “quadrangular in cross-section and thereby similar to Spirodiscus grimaldii but straight”. Similar tubes from the Indian Ocean (near Amsterdam Island, 2200 m) were found co-occurring with typical coiled S. grimaldii. These Indian Ocean specimens of B. gregrousei sp. nov. also have the distal parts of their tubes smooth and circular in cross-section. Occasionally these parts can be proportionally very long. The tubes of Bathyvermilia gregrousei sp. nov. resemble quadrangular tusk-shaped tubes of Bathyditrupa hovei in size and tube diameter (compare Fig. 1 B, C with E). However, tubes of B. hovei have a very regular slightly curved shape, a quadrangular tube cross-section with tube edges forming straight angles throughout and distal parts of the tube never become circular in cross-section. The tubes of Bathyvermilia gregrousei sp. nov., although more or less straight and quadrangular in cross-section, have more variable and less regular shapes (Fig. 11 C, D), normally slightly spirally twisted (Fig. 11 H, I), and distal tube parts often become smooth and circular in cross-section. However, the morphology of the animals removed from their tubes is very different. Known ultrastructures for Bathyvermilia cover three species— B. islandica Sanfilippo, 2001 (tube structure is illustrated in the original description), B. langerhansi (Fauvel, 1909) figured by Vinn (2008) and Vinn et al. (2008) and Bathyvermilia challengeri Zibrowius, 1973 (figured in Kupriyanova et al. 2014), thus allowing intrageneric comparison. All three species have tubes with well-developed homogeneous angular crystal ultrastructure (HAC) at least in the outer layer. This highly specialized structure has nothing to do with the IOP ultrastructure described herein for B. gregrousei sp. nov. IOP ultrastructure constituting the inner layer of B. islandica and the entire tube of B. gregrousei sp. nov. is widely distributed among serpulids (Vinn et al. 2008, table 2) and seems to be less specialized, which suggests that HAC ultrastructure may be an apomorphy inside a certain group of Bathyvermilia species. Tube ultrastructure of B. gregrousei sp. nov. in general is similar to those described for Bathyditrupa and Spirodiscus, being also composed of elongated crystals similar in size and shape. However, the inner part of the wall of B. gregrousei sp. nov. is made of larger elongated, not smaller isometric crystals. Moreover, an outer layer with SOIOP structure representing crystal “bundles” oriented subparallel to the tube surface and growth direction, characteristic for Spirodiscus and Bathyditrupa, is absent in B. gregrousei. At the same time, unilayered tube walls built of more or less chaotically oriented elongated crystals are not unique to Bathyvermilia but known for a wide range of serpulid taxa (see Vinn et al. 2008). While making comparisons based on descriptions only is difficult, among figured ultrastructures the most similar one is known for Protis hydrothermica (see ten Hove & Zibrowius 1986, fig. 4 a, b) that seems to be relatively close to Bathyvermilia (Kupriyanova & Nishi 2010). Very diagnostic for the B. gregrousei sp. nov. are microcavities surrounding the lumen and observed in all three specimens studied with SEM. Although cavities of various morphology are known in some taxa (e.g., Bianchi 1981: fig. 27 b, c, 32 a– c), such tiny ones surrounding the entire lumen were not previously described for any other serpulid.Published as part of Kupriyanova, Elena K. & Ippolitov, Alexei P., 2015, Deep-sea serpulids (Annelida: Polychaeta) in tetragonal tubes: on a tube convergence path from the Mesozoic to Recent, pp. 151-200 in Zootaxa 4044 (2) on pages 171-176, DOI: 10.11646/zootaxa.4044.2.1, http://zenodo.org/record/23503

Tube: white, straight, ostensibly free, quadrangular in cross-section, occasionally and locally pentagonal. Edges may be slightly serrate, especially in younger tube parts. Tube sides slightly concave. Distal part of tube circular in cross-section, smooth, with small peristomes resembling circular rings (Fig. 14 A, D). Tube ultrastructure: wall two-layered, inner layer occupying almost entire thickness, with spherulitic irregularly oriented prismatic ultrastructure (SIOP) containing abundant micritic cement. Inner layer made of small 1 Μm or less densely packed spherulites of irregular shape, but more or less isometric. Spherulites appear as aggregates of very small crystals with common crystallization centre, precise shape of spherulites unclear, their size uniform throughout wall (Fig. 13 A–D), but relatively large near the tube edges, especially in middle part of the wall (compare Fig. 13 I and Fig. 13 J). Outer layer uniformly thin (~ 5 Μm; corresponding wall thickness 180 Μm), having spherulitic prismatic structure (SPHP), consisting of elongated spherulites with growth direction perpendicular to tube surface (Fig. 13 B, H). Tube mineralogy: 100 % calcite (I calc= 447). Radiolar crown: 5–7 pairs of radioles arranged pectinately, not joined by inter-anterior membrane. Stylodes absent. Peduncle: inserted as 2 nd dorsal radiole, with about same thickness as other radioles, with pinnules (Fig. 14 C). Pair of lateral wings proximal to opercular bulb absent. Operculum: inverted cone covered with flat or slightly concave chitinous endplate, constriction distinct (Fig. 14 C). Pseudoperculum absent. Collar and thoracic membranes: collar subdivided into 3 lobes, 2 small latero-dorsal and wide and longer ventral one (Fig. 14 B). Thoracic membranes relatively wide, about same width throughout, ending between 2 nd and 3 rd chaetiger. Thorax: with 7 thoracic chaetigers, 6 of which uncinigerous (Fig. 14 B). Thoracic tori of similar size along thorax, parallel, not shifted dorso-ventally (no triangular depression). Collar chaetae limbate of two sizes, special chaetae absent (Fig. 14 E); other thoracic notochaetae limbate of two sizes and Apomatus chaetae (Fig. 14 F). Uncini rasp-shaped with around 15 teeth in profile view and 4–5 teeth in frontal view, dental formula P: 4: 5: 5: 5: 5: 5: 5: 5: 5: 5: 4 (Fig. 14 I); anterior peg rectangular flattened with crenulated edge. Abdomen: up to 70 segments. Abdominal uncini rasp-shaped, with 12–14 teeth in profile view and 4–5 rows in frontal view, anterior peg rectangular flattened with crenulated edge, dental formula P: 3 (4): 4: 4: 4: 5: 5: 5: 5: 5: 5 (Fig. 14 K). Abdominal chaetae flat geniculate with edge made of rounded denticles (Fig. 14 G, H), replaced by longer limbate capillaries only on very last 10–12 posterior segments (Fig. 14 J); each chaetiger normally with a single chaeta. Posterior glandular pad absent (Fig. 14 J). Size: Total body length up to 18 mm, including up to 6 mm long radioles, width of thorax up to 0.65 mm. Tube total length up to 50 mm, outer diameter up to 0.9 mm, corresponding lumen diameter 0.55 mm. Thickness of tube wall in between angular margins varies in range 1 / 8 – 1 / 4 th of outer diameter. Distribution. Coral Sea, New Caledonia area, including Loyalty Islands, 490–1710 m. Etymology. Named after Dr Helmut Zibrowius who initiated this study. Remarks. SIOP tube ultrastructure was reported for a large number of serpulid genera (Vinn et al. 2009), many of which are unrelated. Two species reasonably close to the new species and having reported SIOP structure are Vermiliopsis infundibulum (Philippi, 1844) and Pseudovermilia madracicola ten Hove, 1989. However, both of them have unilayered tubes, without an external SPHP layer (Vinn et al. 2008) and thus, cannot be confused with Zibrovermilia zibrowii gen. et sp. nov. The differentiation of SIOP structure from a relatively more common IOP structure may be difficult when spherulites are small and irregularly shaped as in the studied species. For example, in Vinn et al. (2008) V. infundibulum is reported to have IOP structure in one paragraph (Vinn et al. 2008: 645), but SIOP structure in another (ibid.: 635, table 2).Published as part of Kupriyanova, Elena K. & Ippolitov, Alexei P., 2015, Deep-sea serpulids (Annelida: Polychaeta) in tetragonal tubes: on a tube convergence path from the Mesozoic to Recent, pp. 151-200 in Zootaxa 4044 (2) on pages 182-185, DOI: 10.11646/zootaxa.4044.2.1, http://zenodo.org/record/23503

R/V JEAN CHARCOT, cruise BIOCAL, 1985, approximately 100 km South of New Caledonia, St. CP 27, 29.8.1985, 23°05.52'S, 166 ° 26.41 'E, 1900 m (1 paratype without radioles AM W. 46386, partly prepared for SEM). Description. Tube: white opaque, ostensibly free, with shiny surface, straight, thick-walled, mostly quadrangular in cross-section, edges rounded and never denticulate. Juvenile tubes with sharper keels, becoming rounded in adults. Tubes slightly twisted, growth stops accompanied by sudden turns of tube around growth axis. Sides usually slightly convex, sometimes slightly concave. Tube ultrastructure: wall unilayered with irregularly oriented prismatic (IOP) structure, in inner wall part transforming into semi-ordered irregularly oriented prismatic (SOIOP). Tube wall not clearly subdivided into layers, in longitudinal section revealing only larger isometric to slightly elongated crystals with size up to 5 µm long (Fig. 11 A–D). Crystal size smallest near lumen (Fig. 11 D), increasing in middle (Fig. 11 C), and becoming largest in outer part of the wall (Fig. 11 B). Cross-section showing distinct zone in inner wall part consisting of highly ordered cigar-shaped crystals (5–6 µm in length, 1–1.5 µm in diameter, Fig. 11 J) with long axes oriented parallel to tube surface (Fig. 11 E, J) resulting in SOIOP ultrastructure; in longitudinal sections this structure is unrecognizable. Transition from IOP to SOIOP structure gradual (Fig. 11 J). Parabolic growth lamellae (Fig. 11 A, C) present in all studied sections, axis of parabolae located in wall centre. Tube mineralogy: 97–100 % aragonite (I arag= 69), doubtful calcite content. Radiolar crown: with 7 pairs of radioles in holotype (radioles mostly missing in paratype), arranged pectinately, easily detachable from short radiolar lobes. Inter-radiolar membrane and stylodes absent. Terminal filaments of radioles thin, spirally twisted. Radiolar eyes and mouth palps not observed. Peduncle: smooth, cylindrical, thin (approximately same thickness as radioles), distal wings absent; inserted conspicuously outside radiolar crown proper, between base of 1 st and 2 nd radioles (Fig. 12 B). Collar and thoracic membranes: collar covering radiolar lobes, thin; trilobed, with ventral lobe slightly higher than the lateral ones (Fig. 12 B). Collar continuous with short thoracic membranes ending at 2 nd chaetiger. Operculum: soft membranous, semi-transparent, mostly globular, but with flattened top, slightly differentiated from the basal part; conspicuous constriction and additional small vesicular ampulla between operculum and peduncle (Fig. 12 A). Pseudoperculum absent. Thorax: with 6 chaetigerous segments, 5 of which uncinigerous. Small bundle of collar chaetae, of two types: simple limbate and fin-and-blade with the distal blade separated from the basal fin by a short gap (Fig. 12 C, D). Subsequent chaetae limbate, of two sizes, Apomatus -chaetae absent (Fig. 12 E). Uncini along entire thorax raspshaped, with 20–25 small teeth in profile view, with 6–8 teeth in the row above flat anterior peg made of 3–4 rounded lobes, dental formula P: 8: 7: 7: 7: 6: 6: 6: 6: 6: 6: 6: 6:?:?:?:?:?:?:? (Fig. 12 F, G). Pair of prostomial eyes absent. Triangular depression absent, thoracic tori almost parallel to mid-ventral line of the thorax. Abdomen: with up to 60 segments. Chaetae long, nearly capillary with only narrow geniculate tip clearly made of two rows of pointed teeth (Fig. 12 I). Capillary chaetae present in posterior chaetigers. Uncini rasp-shaped with over 20 teeth in profile and up to 9 rows of teeth (Fig. 12 J, K) above anterior peg flat divided into 3–5 rounded lobes (crenulated). Dental formula P: 9: 7: 5: 4: 3: 4: 3: 2:?:? or P: 8: 5: 5: 5: 4: 4: 4:?:?. Achaetous anterior abdominal zone long. Size: total body length up to 15 mm, including up to 9 mm long radioles, width of thorax up to 0.5 mm. Tubes incomplete and broken into fragments, maximum total length of fragments (in paratype) 40 mm. External tube diameter up to 1.3 mm, corresponding lumen diameter 0.9 mm. Thickness of tube wall in between the angular margins about 1 / 3 – 1 / 4 th of outer diameter, and up to 1 / 2 when measured across keels. Etymology. The species is named after Dr. Dieter Fiege (SMF) in recognition of his important contributions to taxonomy of Serpulidae. Distribution. Coral Sea off New Caledonia, 1820–1980 m. Remarks. The new species from New Caledonia resembles H. macintoshi (Gravier, 1911) in having a globular transparent, only slightly differentiated operculum. However, the tube of H. dieteri sp. nov. is distinct in being polygonal (quadrangular). Four other Hyalopomatus spp. with known tube ultrastructures are H. variorugosus Ben-Eliahu & Fiege, 1996 (see Sanfilippo 1998 a; Vinn et al. 2008), H. claparedii Marenzeller, 1878, H. marenzelleri Langerhans, 1884 and H. madreporae Sanfilippo, 2009 (see Sanfilippo 2009). Ultrastructural type and shape of crystals of H. variorugosus are very similar to those of H. dieteri sp. nov., despite chaotic orientation of crystals without defined SOIOP ultrastructure in the former. H. marenzelleri demonstrates squat prismatic crystal shapes, but the ultrastructure type is still the same (IOP). The closest to H. dieteri sp. nov. is H. claparedii that has a well-defined SOIOP ultrastructure near the lumen (Sanfilippo 2009, fig. 6 E) with a gradual transition to IOP ultrastructure in the outer part of the tube wall. The tube of H. madreporae also shows a similar pattern, but its SOIOP zone (Sanfilippo 2009, fig. 4 G) seems to be relatively wider than those in both H. dieteri sp. nov. and H. claparedii. All Hyalopomatus spp. studied to date have very similar tube ultrastructures supporting the generic placement of the new species described herein.Published as part of Kupriyanova, Elena K. & Ippolitov, Alexei P., 2015, Deep-sea serpulids (Annelida: Polychaeta) in tetragonal tubes: on a tube convergence path from the Mesozoic to Recent, pp. 151-200 in Zootaxa 4044 (2) on pages 177-180, DOI: 10.11646/zootaxa.4044.2.1, http://zenodo.org/record/23503

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
Intern experience at CH���M Hill, Inc.: an internship report
No full textIncludes author's vita"Submitted to the College of Engineering of Texas A&M University in partial
fulfillment of the requirement for the degree of Doctor of Engineering."Includes bibliographical referencesA review of the author's internship experience with CH���M HILL, Inc.
during the period September 1975 through May 1976 is presented. During this nine month
internship the author worked as an Engineer II in the Industrial Processes discipline of this
large consulting engineering firm... The author's prime responsibility was as one of three
lead design engineers on the design of a large wastewater treatment facility for a pulp mill
in Hoquiam, Washington owned by ITT Rayonier Inc. The work generally consisted of the design
of individual treatment units and associated piping and pumping. The purpose of the project
was to provide wastewater treatment capabilities that would satisfy the effluent limitations
(standards) imposed upon the mill by the State of Washington Department of Ecology and the
U.S. Environmental Protection Agency. The author's assignment also entailed necessary
interaction with the project manager and other CH���M HILL design engineers and support staff
members, the client's representatives, and representatives of two other consulting engineering
firms working on the project. Thus, the internship position at CH���M HILL provided considerable
experience coordinating the author's work with the work of other engineers, guiding the design
and administrative efforts of a support staff, and interacting regularly with the client and
other consulting firms. This broad exposure to a variety of engineering and organizational
problems provided a valuable educational experience
