No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-graduação em LiteraturaEste trabalho tem como objetivo reunir e recuperar leituras críticas esparsas da obra de João Simões Lopes Neto publicadas na revista Província de São Pedro e no suplemento literário Caderno de Sábado, facilitando a pesquisa de outros estudiosos interessados em sua obra. O trabalho de transcrição foi realizado seguindo as normas padronizadas pela Filologia contemporânea, a fim de determinar os critérios adotados para a transcrição dos textos. Num primeiro momento, apresenta-se a apreciação da obra simoniana por parte dos críticos e, num segundo momento, são apresentados os vinte e oito textos selecionados para a transcrição
Brasineura troglophilica Silva-Neto & Garcia Aldrete. Recently 2015
No full textBrasineura troglophilica Silva-Neto & García Aldrete, 2015 Variation in the fore wing veins (Figs 9–12) The pattern in the fore wing M vein described by Silva-Neto & García Aldrete (2015) for B. troglophilica is M six branched, with M6 forked resulting in M6a and M6b, but two of the three male specimens collected in 1982 in the Brazilian state of Pará show the following variations: M seven branched, with M7 three branched, resulting in M7a,M7b and M7c (Fig. 9); the other specimen shows M with seven primary branches, with M7 and M4 forked (Fig. 10). A third specimen has the same pattern as the holotype (Fig. 11). The paratype of B. troglophilica has the fore wing M vein six branched, with M6 three branched (Fig. 12).

Abstract:
This paper investigates performance impairments due to constraints imposed by the MAC layer when single-mode fiber (SMF) is used to extend the reach of an IEEE 802.11 network. It is shown that data throughput decreases as fiber length increases. It is also noted that the network fails long before physical layer limitations set in due to the timeout values defined within the MAC protocol. This study is based on both variants of the IEEE 802.11 Distributed Coordination Function. Moreover, both UDP and TCP packet transmissions are taken into account. An experimental enquiry is initially developed to provide a set of validation points before extending these results by simulations using the OPNET platform. Finally, an analytical approximation is presented to these results that allows designers of Radio-over-fiber (RoF) systems to quickly and accurately predict the data throughput given the specific parameters of their network. To our knowledge, this is the first analysis of this kind for a long reach fiber system
Cearagrylloides microcephalus Martins-Neto, n. comb.
No full textCearagrylloides microcephalus Martins-Neto, n. comb. (Figs. 2 B, E, G) 1. Cearagryllus microcephalus Martins-Neto, 1991. Specimens included. GP/ 1 T- 1680 (holotype), RGMN- 203, CV- 1699, and RGMN- 40 (510) New supplementary material. RGMN- 508. Emended diagnosis. Females with robust body, varying from 24 to 26 mm length; fore wing length varying from 24 to 28 mm; ovipositor length around 38 mm. Ovipositor 1.6 times longer than the body and/or the fore wing length. Head notably small, laterally elongated. ScP straight, not thickened; R parallel to ScP. MP unbranched; around six MP 2 secondary branches. r-m indistinct. Discussion. The specimen CV- 1699, with incompletely preserved ovipositor, was initially interpreted as belonging to the species Cearagryllus perforatorius (Martins-Neto, 1991), based just on the body and wing length. However, after re-examination of the venation of this specimen, it is now possible to verify that it belongs to Cearagrylloides microcephalus. In addition to the original characters assigned to the species (smaller body and head, longer ovipositor), the fore wing provided other important characters. In C. perforatorius ScP is sigmoid, distally divergent and basally thickened, in contrast to C. microcephalus, which exhibits a straight ScP, not thickened. Additionally, MA has typically three anterior secondary branches, not present in C. microcephalus. Another minor difference is a smaller number of MP secondary branches.Published as part of Martins-Neto, Rafael Gioia & Tassi, Lara Vaz, 2009, The Orthoptera (Ensifera) from the Santana formation (Early Cretaceous, Northeast Brazil): A statistical and paleoecological approach, with description of new taxa, pp. 21-37 in Zootaxa 2080 on page 28, DOI: 10.5281/zenodo.18734
