Turris (Annulaturris) munizi Vera-Peláez, Vega-Luz & Lozano-Francisco, 2000: 10: pl. 1, fig. 9, pl. 2, fig. 7, pl. 7, figs 1–3 (as Annulaturris munizi); Robin 2008: pl. 448, fig. 15. Type loc.: Balut Is., Mindanao Sea, Philippines, ca 30 m, coralline bottom. Syn. Nov. Description: Shell fusiform (b/l 0.29–0.38), with short, straight siphonal canal (a/l 0.39–0.46), last whorl with rounded periphery, spire straight-sided to slightly cyrtoconoid, whorls convex, without peripheral angle, suture somewhat deep but narrow; outer lip evenly convex, with 6–9 strong spiral threads inside, anal sinus relatively shallow, slightly V-shaped. Sculptured by well-defined, but rather low and narrow spiral cords, their intervals with thin intermediary threads roughened by crinkled collabral threads. Subsutural cord relatively low, bearing an angular thread, with a weaker one on either side; sulcus very narrow and deep. Sinus cord above median, nearly as prominent as peripheral cord, declivously flattened, bearing 2 spiral threads, strongly crenulate but not gemmulate. Base of penultimate whorl with 2–3 anterior cords, the peripheral cord not particularly prominent, the 3 rd cord sometimes weak. Base of last whorl with very approximately 15–25, some weaker and paler, with finer threads in intervals, fine to obsolete on tip of rostrum. Collabral threads distinct, rendering basal cords somewhat granular. White to pale brown with main spiral ridges orange-brown; protoconch white. Protoconch (f. Vera-Peláez et al. 2000) papilliform, ca 3.5 convex whorls, with arcuate, opisthocline axial riblets, suture covered by a thin, white ridge. Attains 90.5 mm in length. DISTRIBUTION: SW Japan to Southern Philippines and Papua New Guinea, depth reportedly 30 m to ca 360 m. TYPES: G. lululimi: Holotype and one juvenile paratype presently in BO colln. T. munizi: Holotype in Vera-Lozano colln. OTHER MATERIAL EXAMINED: JAPAN: off Cape Shiona, Wakayama Prefecture, 150–200 m (Shingo Habu colln, ex Akira Inada); off Irino, Kochi Prefecture, 120–130 m (Shingo Habu colln). PHILIPPINES: Oslob, S. Cebu, 360 m, and Aliguay Is., from fishermen (G. Poppe colln); Aliguay Is., Zamboanga, 24–40 fath. [44–73 m] (BO colln); PAPUA NEW GUINEA: BIOPAPUA Expedition, Stn. DW 3770 (MNHN—IM- 2009-17042). REMARKS: Superficially, this species appears to be intermediate in characters between Gemmula and Turris, but has a sinus cord that is low and non-peripheral, and distinctly crenulate, not truly gemmulate as in the former. G. lululimi appears to be characterised by the brown ridges on a white ground, its short siphonal canal and the strongly crenulated sinus cord.Published as part of Kilburn, Richard N., Fedosov, Alexander E. & Olivera, Baldomero M., 2012, Revision of the genus Turris Batsch, 1789 (Gastropoda: Conoidea: Turridae) with the description of six new species, pp. 1-58 in Zootaxa 3244 (1) on pages 56-57, DOI: 10.11646/zootaxa.3244.1.1, http://zenodo.org/record/24632

Outer lip in side view convex (slightly opisthocline), with a distinct stromboid notch, edge of lip fluted; siphonal canal moderately shallow, linear, expanding at edge. Surface smooth and glossy, spiral cords low, in t/s weakly and gradually rounded to broadly and weakly angular, intervals shallow; suture shallow. Subsutural cord strongly impressed, weakly rounded, with a very slight median ridge; sinus cord narrow, medially sunken. Peripheral cord weakly projecting, very slightly angular, base of whorl with a similar but weaker and narrower cord, bordered above and below by a fine intermediary thread. Upper part of base with three low, weakly defined cords, with a finer intermediary between each pair; rostrum with 5–6 fine ridges. becoming obsolete towards termination. Early whorls with the subsutural cord distinctly bifid, peripheral cord angular. Porcellaneous white to pale brown, main spiral cords with conspicuous rounded or rectangular black or brownish-black spots with white intervals, subsutural region and a broad interrupted band around upper part of base with a dark to reddish-brown suffusion, intervals between cords sometimes similar ly brown; aperture and inner lip white. Attains ca 95.5 mm in length. DISTRIBUTION: Japan to Philippines and Solomon Islands, west to Admiralty Is. (Olivera et al. 2000, as T. babylonia). TYPE LOCALITY: Davao Gulf, Mindanao, PHILIPPINES TYPES: Holotype (Pl. 7, figs A–B) 7.07 ºN, 125.71 ºE, Samal Is, Davao Gulf, PHILIPPINES, dived, purchased from dealer, August, 2010; dimensions 95.5 x 25.9 mm, MNHN 24944. Paratype 1 (Pl. 7, fig. C), same locality, 94.0 x 25.5 mm, (NHMUK 20110208); Paratype 2 (Pl. 7, fig. D), same locality, 86 x 22.6 mm (ANSP 426053); Paratype 3 (Pl. 7, fig. E), same locality, 93 x 23.4 mm (MNHN 24435) Turris gothica, T. rustica, T. pyramidalis, T. vitrea: originally Chemnitz collection and NMPG (Bolten colln), are now apparently lost; the same Chemnitz reference, showing an unidentifiable shell, is given to all. P. marmorata: syntypes possibly in URM and Chemnitz colln, but now probably lost. REMARKS: Powell (1964) pointed out the existence of a shorter, broader form of Turris babylonia— which he incorrectly regarded as typical—and a slender one (which he equated with Pleurotoma raffrayi Tapparone-Canefri, 1878, but see Turris undosa). However, the lectotype of Murex babylonius is in fact a narrowly fusiform shell, with a spire angle of 22 º– 25 º and a longer, straighter siphonal canal. Turris chaldaea, apart from its different proportions, has a relatively shorter siphonal canal, with a distinct stromboid notch and a dark zone below the suture, not seen in T. babylonia. Olivera et al. (2010) demonstrated the two to be distinct species, but erred in identifying the broader, more biconic specimens as the true Turris babylonia. The name Turris gothica Röding, 1798, is probably the earliest applicable to the present species, but not only has this name never been used subsequently, but its identity is dependent on Chemnitz’s figures, which lack sufficient details for certainty. ETYMOLOGY: chaldaeus, resembling the script of the people inhabiting the area of Babylon (Chaldaean), Latin adjective.Published as part of Kilburn, Richard N., Fedosov, Alexander E. & Olivera, Baldomero M., 2012, Revision of the genus Turris Batsch, 1789 (Gastropoda: Conoidea: Turridae) with the description of six new species, pp. 1-58 in Zootaxa 3244 (1) on pages 14-16, DOI: 10.11646/zootaxa.3244.1.1, http://zenodo.org/record/24632
Ohmic treatment of fresh foods: Effect on textural properties
No full textThe aim of this work was to verify the effects of ohmic heating (OH) treatment on texture of fresh solid food (without pre-treatment in brine solutions), subjected to constant electrical field gradient (1100 V/m; 2200 V/m; 3300 V/m). Samples of fresh potatoes, carrots and apples cut into cylinders (d = 30 mm, h = 9.0 mm) underwent OH for 60, 120, 180 and 240 seconds. Texture measurements were performed in a universal testing machine Instron 4301, with a 100 N load cell, using a single-cycle compression test. The raw untreated sample was used as control. Stress–deformation behavior of food samples processed by OH differs appreciably from raw untreated samples for all cooking times. Firmness of solid samples decreased with OH time. This study confirmed that OH significantly affects texture of solid foods, producing structural damage, even though food has a low electrical conductivity.Fil: Olivera, Daniela Flavia.

MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank

DESCRIPTION: Spire angle 25–28 º, b/l 0.27-0.30, a/l 0.41–0.49, with an acuminate, orthoconoid spire, siphonal canal straight, moderately thick but tapering, is approximately equal to the aperture; whorls with periphery more or less median, suture channelled; teleoconch whorls ca 16 (apex more or less worn in all seen). Anal sinus shallow, tongue-shaped, parallel-sided, bordered by a raised flange; interior of aperture with 4–7 well-spaced spiral ridges. Sculptured by strong spiral cords with narrow intervals, containing collabral threads. Subsutural cord well-defined, consisting of two irregularly and weakly crenulate ridges, the posterior one slightly weaker but forming a flange bordering suture, sometimes a third ridge above sulcus. Sulcus deep and narrow. Sinus cord peripheral, slopingly flat-topped and concave to very shallowly bifid, often no wider than other cords, irregularly crenulated by shallow lunulate grooves. Base of spire whorls with two main cords, each unequally and deeply bifid, forming a thin accessory cord on its anterior margin; a 3 rd main cord sometimes just visible above suture; intervals between main cords deep, much narrower than cords. Base of last whorl with 18–20 strong, irregularly nodose spiral cords, posteriorly with some interstitial ridges, a variable development of microscopic threads in intervals and on sides of cords; ridges on rostrum finer, closer and more even, becoming obsolete near end, rendered rugose by collabral threads. Collabral threads thin but strong, forming oblique lamellae in sulcus. Traces of pale periostracum in interstices between spiral cords. White with some light brown blotches or flecks, particularly below suture, or pale buff with white cords, anal cord sometimes marked with arcuate brown lines (creating a gemmulate appearance); rostrum and aperture white. Protoconch (photomicrograph courtesy of B. Olivera) bluntly conical, ca 3 whorls, the last with arcuate, suture-tosuture axial riblets; breadth ca 0.76 mm. Attains 61 mm.

Colour uniform reddish-brown with a persistent brown periostracum overall. Turris kathiewayae: Suture shallowly channelled; spiral cords high, with deep, relatively wide intervals, most main cords compound (with 1–2 weaker ridges cut off on the anterior face); subsutural cord prominent, bearing 2–3 strong ridges; sinus cord usually irregularly crenulated by very shallow lunulate grooves. Colour off-white, to pale brown with diffuse pale brown marks, crests of ridges with brown spiral lines; periostracum interstitial. A specimen from Noumea differs from all others seen in colouration, which is light brown with a white sinus cord; there are also minor sculptural differences. The significance of these differences is unknown.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
