Origens e ramifica??es das artérias aortas esquerda e dorsal do jabuti (Geochelone carbonaria, Spix, 1824)
FARIA, Tania Negreiros;MARIANA, Arani Nanci Bomfim;
Brazilian Journal of Veterinary Research and Animal Science , 2001, DOI: 10.1590/S1413-95962001000400002
Abstract: we worked with 6 tortoises, 3 females and 3 males of the species geochelone carbonaria, in order to describe the main arteries, which vascularize the organs of the coelomic cavity. we observed that the left aorta lengthen three main branches in order to irrigate the organs of the animal's cranial area, before it joins the right aorta to form the dorsal aorta, which is in charge of the nutrition of the caudal area of the animal, through several branches coming irregularly in quantity and origin.

Assis-Neto, Ant?nio Chaves de;Carvalho, Maria Acelina Martins de;Melo, Maria Isabel Vaz de;Miglino, Maria Angélica;Oliveira, Moacir Franco de;Mariana, Arani Nanci Bomfim;
Brazilian Journal of Veterinary Research and Animal Science , 2003, DOI: 10.1590/S1413-95962003000700010
Abstract: the agouti (dasyprocta aguti) is a wild rodent that, in the northeast region of brazil, is a species that is very used by the low-income population as an alternative protein source for human feeding. thirty-one male agouti were used, coming from the universidade federal do piauí (ufpi) - piauí state, and from escola superior de agricultura de mossoró (esam) - rio grande do norte state - brazil. the animals were divided in to age groups, from the birth to fourteen months old. the average diameter average of the nucleus was obtained by measuring 10 nuclei of the studied cellular type, in each testicle that was in the stage i of the seminiferous epithelium cycle. this was performed in animals that did not present an organized epithelium in well-defined periods due to the age, and measurements were made in transversal sections chosen only for the circular contour. the beginning of the asynchronism of the spermatogenic process was observed since the six months of age. the puberty of the agouti dasyprocta aguti was definitely established at nine months of age, because all the cellular types and free spermatozoa in the tubular lumen were present in a large extent of the testicular parenchyma.

International Journal of Morphology , 2005,
Abstract: During this study, fifteen shark heads of sand tiger shark Carcharias taurus (Rafinesque, 1810) were analyzed. The studied material was obtained in the Santos Fishing Terminal, S o Paulo, Brazil. The heads dissection was focused on the characterization of the mandibular muscles and on the description of the mandibular branch of the trigeminal nerve. The C. taurus mandibular muscles are represented by: m. preorbitalis, m. levator palatoquadrati, m. quadratomandibularis and m. intermandibularis. The origin of the trigeminal nerve of C. taurus is located in a lateral portion of the medulla oblongata. In the orbita, the trigeminal nerve branches off to originate the mandibular branch that innervates the muscles which are derived from the mandibular arch. The proximal branches of the trigeminal nerve mandibular branch innervate the m. levator palatoquadrati. The muscles preorbitalis and quadratomandibularis receive fibers from the intermediate branches of the trigeminal nerve mandibular branch and the distal ramification of the mandibular branch can be visualized in the m. intermandibularis Fueron analizadas 15 cabezas de tiburón toro Carcharias taurus (Rafinesque, 1810), obtenidas en el Terminal Pesquero de Santos, S o Paulo, Brasil. La disección permitió caracterizar los músculos mandibulares y describir la rama mandibular del nervio trigémino. Los músculos mandibulares de C. taurus son: M. preorbitalis, M. levator palatoquadrati, M. quadratomandibularis y M. intermandibularis. El origen aparente del nervio trigémino de C. taurus está localizado en la porción lateral de la médula oblonga. En la órbita, las ramas del nervio trigémino salen para dar origen a la ramificación mandibular, la cual inerva a los músculos derivados del arco mandibular. Las ramificaciones proximales de la rama mandibular del nervio trigémino inervan al M. levator palatoquadrati. Los Mm. preorbitalis y quadratomandibularis reciben fibras de las ramas intermedias de la ramificación mandibular del nervio trigémino, y el M. intermandibularis recibe la ramificación distal de la rama mandibular del nervio trigémino
History of Media in Bengal: A Chronological Overview
Arani Basu
Transcience : a Journal of Global Studies , 2013,
Abstract: Here attempts have been made to chronicle the journey of media in Bengal from the end of the 18th till today, with reference to the concomitant political changes that the state has faced along with. Whether vernacular or English, or print or electronic, media in Bengal has been in close association with the former’s political affiliations and functioning. Therefore, this article would try to capture the evolution of media in the state of West Bengal, which was the Mecca of journalistic discourse right from the renaissance period, and still holds its relevance at the national level.
Revisitando a "epistemologia social": esbo?o de uma ecologia sociotécnica do trabalho intelectual
Oddone, Nanci;
Ciência da Informa??o , 2007, DOI: 10.1590/S0100-19652007000100008
Abstract: formulated in 1952 by margaret egan and jesse shera, two american researchers in the library science field, the concept of 'social epistemology', envisaging the study of the production, flow and consumption of any sort of "intellectual product", received limited acceptance and was slightly discussed within the specialized literature of that period. resuming the concept and relating it to ideas and theories conceived by contemporary authors as foucault, lévy and latour, this paper suggests that 'social epistemology' might be understood as the study of the reciprocal relations that are established between human beings and their changing social, cultural and technological environment regarding the cognitive activity or, in other words, regarding the cycle of knowledge production, circulation and use, featured in its materiality as a socio-technical ecology of the intellectual labor. settled in this articulated manner, such a conceptual framework could be adopted by information science researchers as a relevant and interesting theoretical foundation for their scientific investigations.
O IBBD e a informa??o científica: uma perspectiva histórica para a ciência da informa??o no Brasil
Oddone, Nanci;
Ciência da Informa??o , 2006, DOI: 10.1590/S0100-19652006000100006
Abstract: there's little controversy over the fact that information science appeared in brazil in 1970, breaking traditional bibliographical practices that weren't any longer able to properly answer the requirements of an expanding scientific community. examining the documents gathered in the personal archive of lydia de queiroz sambaquy, the brazilian librarian who conceived the instituto brasileiro de bibliografia e documenta??o (ibbd) and directed it between 1954 and 1965, the results of this historical research suggest, on the contrary, that the activities developed within ibbd during those eleven years were actually marked by an "informational" approach of the bibliographic work, according to the conceptions of farradane, one of the founders of the field. simultaneously influenced by librarianship, documentation and the concept of "scientific information", then a very modern one, the services provided by the librarians of ibbd under the leadership of lydia sambaquy opened a new field of professional action, defining the conditions under which the future birth of information science was made possible.
“The bright past”, or whose (hi)story? Challenges in Russia and Serbia today
Adler Nanci
Filozofija i Dru?tvo , 2012, DOI: 10.2298/fid1204119a
Abstract: In Russia, two decades after the collapse of the Soviet Union, Stalin’s popularity soared in nationwide polls, as many recalled the country’s former prestige and their previous sense of security. Likewise, many Serbs, who formed the largest group in former Yugoslavia, look back with nostalgia to a time of greater national pride and material comfort. By contrast the dominated ethnic populations in that same nation at that same time were frustrated in their striving for national pride. Each polity has a story fashioned by selected and connected events that promote its national interests. Although the physical battle in former Yugoslavia has ended, the divisiveness remains, and is perpetuated by competing narratives of what happened and why. And in Russia, an increasingly emergent “invisible Stalinism” has once again given victims of the repression little validation of their experience. This article offers preliminary observations on the disjunction of narratives in Russia and Serbia, and seeks to explain one of the key impediments to coming to terms with the past.
Preparation of Pure DyBa2Cu3O7-X Nanocluster Superconductors Using Biopolymer Chitosan
Alikhanzadeh Arani S.,Azimzadeh Arani M.
Proceedings of the International Conference Nanomaterials : Applications and Properties , 2012,
Abstract: We used sol-gel method for synthesizing nanoclusters of DyBa2Cu3O7-X high TC type II su-perconductor in presence of biopolymer chitosan. In the first stage, the precursor and biopoly-mer aggregated into amorphous matrix and hydrogels are then formed by thermogelling. The fibrous nature of the biopolymer chitosan is retained at high temperatures up to 500 °C. After heating to 900 °C, complete decomposition of BaCO3 and formation of the superconductor na-noparticles (with a diameter of 10-20 nm) occurred subsequently. Characterization of speci-mens was performed using scanning electron microscopy and transmission electron microscopy, supported by other techniques including XRD diffraction, energy dispersive X-ray, FT-IR spectrum and magnetic susceptibility measurements.
