No full textAenigmachanna, new genus Type species: Aenigmachanna gollum Diagnosis. Distinguished from Channa and Parachanna by the following characters, which are unique among channids: a very slender (maximum body depth only 11.1–11.3% SL), eel-like body (head length only 20.8–21.6% SL), large mouth (jaw length 60.4–61.1 % HL), 43–44 anal-fin rays, absence of a body lateral line with pored scales, 83–85 scales in a lateral series, colour pattern and absence of buoyancy. It is further distinguished from other channids by the following combination of characters: 64 vertebrae, 56–57 dorsal-fin rays, and the absence of pelvic fins. Etymology. Derived from the Latin word aenigma, enigma, and Channa, the genus name of Asian snakeheads. Gender feminine.Published as part of Britz, Ralf, Anoop, V. K., Dahanukar, Neelesh & Raghavan, Rajeev, 2019, The subterranean Aenigmachanna gollum, a new genus and species of snakehead (Teleostei: Channidae) from Kerala, South India, pp. 377-388 in Zootaxa 4603 (2) on page 378, DOI: 10.11646/zootaxa.4603.2.10, http://zenodo.org/record/268232
Vijayāṅkā, Vikaṭanitambā, Avantisundarī – modern Sanskrit dramas of V. Raghavan in the context of contemporary Sanskrit literature.
No full textVijayāṅkā, Vikaṭanitambā, Avantisundarī, collectively known as Prekṣaṇakatrayī, are three short Sanskrit plays written in the 20th century in Sanskrit by Venkataraman Raghavan – a distinguished Sanskrit scholar. Until now, there were no research projects or translations of any of these plays. The subject of Prekṣaṇakatrayī is the author’s portrayal of the imagined lives of three Sanskrit poetesses from the past. One of the most important issues of these plays is Sanskrit poetics, which was also a major area of scholarly interests of Dr. Raghavan. Therefore, in order to investigate these dramas properly, they have been studied within a broader context encompassing V. Raghavan’s academic achievements as well as the history of Sanskrit theory of literature. An outline of the dramatic output of Dr. Raghavan is also provided, which portrays him as a modern Sanskrit dramatist.
The dissertation also tackles a problem of contemporary Sanskrit literature, which is a field somewhat neglected by scholars. Sanskrit has a very peculiar status. Although it is not commonly used as a spoken language, people still choose it as a medium of their literary creativity. The dissertation is also an attempt to take a stance in the discussion, whether Sanskrit can be considered a dead language, or whether there is still life in it

Implementation of Algorithm for Satellite-Derived Bathymetry using Open Source GIS and Evaluation for Tsunami Simulation
No full textAccurate and high resolution bathymetric data is a necessity for a wide range of coastal oceanographic research topics. Active sensing methods, such as ship-based soundings and Light Detection and Ranging (LiDAR), are expensive and time consuming solutions. Therefore, the significance of Satellite-Derived Bathymetry (SDB) has increased in the last ten years due to the availability of multi-constellation, multi-temporal, and multi-resolution remote sensing data as Open Data. Effective SDB algorithms have been proposed by many authors, but there is no ready-to-use software module available in the Geographical Information System (GIS) environment as yet. Hence, this study implements a Geographically Weighted Regression (GWR) based SDB workflow as a Geographic Resources Analysis Support System (GRASS) GIS module (i.image.bathymetry). Several case studies were carried out to examine the performance of the module in multi-constellation and multi-resolution satellite imageries for different study areas. The results indicate a strong correlation between SDB and reference depth. For instance, case study 1 (Puerto Rico, Northeastern Caribbean Sea) has shown an coefficient of determination (R2) of 0.98 and an Root Mean Square Error (RMSE) of 0.61 m, case study 2 (Iwate, Japan) has shown an R2 of 0.94 and an RMSE of 1.50 m, and case study 3 (Miyagi, Japan) has shown an R2 of 0.93 and an RMSE of 1.65 m. The reference depths were acquired by using LiDAR for case study 1 and an echo-sounder for case studies 2 and 3. Further, the estimated SDB has been used as one of the inputs for the Australian National University and Geoscience Australia (ANUGA) tsunami simulation model. The tsunami simulation results also show close agreement with post-tsunami survey data. The i.mage.bathymetry module developed as a part of this study is made available as an extension for the Open Source GRASS GIS to facilitate wide use and future improvements
Aenigmachanna gollum Britz & Anoop & Dahanukar & Raghavan 2019, new species
No full textAenigmachanna gollum, new species Figures 1–4 Holotype. BNHS FWF 966, 90.2 mm SL, Oorakam, Malappuram, Kerala, India (11°03’52’’N and 76°01’00’’E) collected by Ajeer on 3 September 2018 from a paddy field. Paratype. BNHS FWF 967, 80.1 mm SL, same information as for holotype. Diagnosis. Same as for the genus. Description. Body cylindrical anteriorly to subcylindrical posteriorly and laterally compressed caudally, elongate, eel-like (Figs. 1,2), its length 8.8–9.0 times its depth, tapering towards tail, where body length is 22–23 times its depth. Head large, with eye situated in anterior third of head. Nasal organ large, about 1/10 head length, anterior naris at end of elongate nasal tube, posterior naris a large opening in front of eye. Mouth large (Figs. 1-3), jaw length nearly 2/3 head length. Premaxilla with several rows of strong recurved teeth, larger near symphysis and smaller and only in single row more posteriorly. Vomer with up to 10 strong conical teeth, six prominent teeth on palatine arranged in a single row. Dentary with several rows of smaller but strong and recurved teeth on patch near symphysis, but with larger caniniform teeth further posteriorly. Five large antrorse teeth on posterior patch of parasphenoid. Fifteen elongate gill rakers on external aspect of first gill arch. Five branchiostegal rays. Head lateral-line pore system with two nasal pores, seven circumorbital pores, two frontal pores, four dentary and one anguloarticular pore, four preopercular pores, one pterotic pore, two extrascapular pores, one posttemporal pore. No pored lateral line scales on body (Fig. 4). Dorsal fin long (Figs. 1,2), nearly three-quarters of standard length, originating at first quarter of body, extending to caudal peduncle, almost reaching caudal fin. Anal fin long (Figs. 1,2), more than half of standard length, originating slightly behind first half of body and in posterior extension mirroring dorsal fin by extending almost up to caudal fin. Caudal fin ovoid (Fig. 1). Pectoral fin large, its posterior margin when adpressed reaching beneath origin of eighth dorsal-fin ray (Fig. 1,2). Pelvic fin absent. Morphometric information is presented in Table 1. Large scales covering top of head, small scales on postorbital area up to opercle (Figs. 2,3). 29 (10 + 19) predorsal scales. Comparatively small scales on anterior postcranial portion of body arranged slightly irregularly, with larger regularly arranged scales from level of anterior dorsal fin base posteriorly. 83–85 scales in lateral series plus 4 scales on caudal-fin base. 13 transverse scale rows. Dorsal fin with 56–57 rays, anal fin with 43–44 rays, caudal fin with 7+7 principal caudal-fin rays and 1 dorsal and 1 ventral procurrent ray. Pectoral fin with 12 rays. Vertebrae 64. Unfortunately, due to the rarity of the material we are unable to comment further on internal features. Colouration. In life (Fig. 1), entire body from head to caudal peduncle uniformly brown dorsally and mostly brown laterally, but with ventral side of head uniformly lighter beige without melanophores; abdominal area mostly beige with scattered dark spots. Scales covering cheek and opercular region exhibiting reflective, silvery areas resulting in a marbled impression. Body at level of individual scales with characteristic colouration (Figs. 1–4): each scale in dorsal half of body with darker brown anterior crescentic area, light brown to yellowish, narrow and crescentic, elongate marking in middle of scales and dark brown posterior blotch-like marking; scales in ventral half of body with light brown to yellowish crescentic mark becoming progressively wider ventrally, in ventrolateral scales entirely replacing anterior dark crescentic area; most scales in ventral abdominal region uniform beige with few brown scales interspersed, forming scattered spots, some of which are arranged in a midventral streak from isthmus to anus. Fin membranes transparent and fin rays light brown with whitish distal tips forming narrow whitish dorsal, caudal, and anal-fin margins. In preservative, colour pattern as above, but reflective silvery area on cheek scales, light brown area on body scales, and beige scales on ventral abdominal body whitish. Distribution. Aenigmachanna gollum is so far known only from the type locality (Figs. 5,6), a paddy field, but a third specimen has been reported from a well at the Village of Peringara near Tiruvalla (9°22’33” N and 76°33’00” E), approximately 250 km south of the type locality. Etymology. Named after Gollum, a character from J. R. R. Tolkien’s books ‘The Hobbit’ and ‘The Lord of the Rings’, a creature that went underground and during its subterranean life changed its morphological features. A noun in apposition. We propose the common name Gollum snakehead for this species. Genetic analysis. Aenigmachanna showed high genetic divergence, with minimum and maximum raw genetic distances ranging from 15.8–24.2% in cox1 for the species of Channa, and with 20.4–22.2% in cox1 for species of Parachanna. Best partition scheme for the data was TNe+I+G4 for first two codon positions of cox1 (BIC = 18328.676, lnL = -8606.791, df=172) and TN+ASC+G4 for third codon position of cox1 (BIC = 18714.922, lnL = -8511.415, df=261). The maximum likelihood tree based on the best partition scheme (Fig. 7) showed a deep divergence between Aenigmachanna gollum and the clades of Parachanna and Channa within Channoidei. Additional studies are needed to place Aenigmachanna gollum with confidence into a phylogenetic framework and to decide whether it is the sister group of Parachanna, of Channa or even of Parachanna plus Channa, as in the cox1 analysis (Fig. 7).Published as part of Britz, Ralf, Anoop, V.
