Proposição de rotina morfológica para detecção de malha viária em imagens orbitais
(2010-01-01)
The outdating of cartographic products affects planning. It is important to propose methods to help detect changes in surface. Thus, the combined use of remote sensing image and techniques of digital image processing has ...
Morphology of the vas deferens of the budgerigar (Melopsittacus undulatus)
(2003-01-01)
A morphological study of the budgerigar vas deferens was conducted to demonstrate the electron-microscopic features of its epithelial lining. The analysis showed that the vas deferens of the budgerigar was found to be of ...
Morphology of Nylon 6/Acrylonitrile-Butadiene-Styrene Blends Compatibilized by a Methyl Methacrylate/Maleic Anhydride Copolymer
(2003-10-21)
The morphologies of nylon 6/acrylonitrile-butadiene-styrene blends compatibilized with a methyl methacrylate/maleic anhydride copolymer, with 3-20 wt % maleic anhydride, were examined by transmission electron microscopy. ...
The role of hierarchical morphologies in the superior gas sensing performance of CuO-based chemiresistors
(2013-04-12)
The development of gas sensors with innovative designs and advanced functional materials has attracted considerable scientific interest given their potential for addressing important technological challenges. This work ...
Morphology of trichomes in Tibouchina sect. Pleroma (D-Don) Cogn. (Melastomataceae)
(Inst Tecnologia Parana, 1999-01-01)
The Melastomataceae display greater trichome diversity. Dr. Wurdack, in his Atlas of hairs, recognized 46 types of trichomes for the Neotropical Melastomataceae through the Scanning Electron Microscope (SEM), and referred ...

(Magnolia Press, 2008-11-05)
The morphology of the eggs and larvae of the ant Cyphomyrmex transversus Emery is here described and discussed for the first time. Some morphological characteristics of the symbiotic fungus that covers the eggs, larvae, ...
Comparison of the external morphology of Rhipicephalus sanguineus (Latreille, 1806) (Acari : Ixodidae) ticks from Brazil and Argentina
(Elsevier B.V., 2005-04-20)
In the present study the external morphology of semi-engorged Rhipicephalus sanguineus females ticks from Brazil and Argentina were compared by scanning electron microscopy. Many differences were detected among the R. ...
Comparative morphology of the tongue in free-tailed bats (Chiroptera, Molossidae)
(Fundação Zoobotânica do Rio Grande do Sul, 2003-06-01)
Descriptive and comparative studies on tongue of nineteen Molossidae, one Mystacinidae, and four Vespertilionidae bats species were carried out. Analysis was restricted to the external morphology, covering general shape ...
Plasticidade fenotípica da morfologia externa de Lippia alba (Mill.) N. E. Br. ex Britt. & Wilson (Verbenaceae) em resposta a níveis de luminosidade e adubação
(2004-06-01)
The objective of this paper was to evaluate the phenotypical plasticity of external morphology of Lippia alba in response to two luminosity level and four organic-mineral fertilization level. The morphological plasticity ...
