Chromosomal features of nucleolar dominance in hybrids between the Neotropical fish Leporinus macrocephalus and Leporinus elongatus (Characiformes, Anostomidae)
(Springer, 2009-11-01)
In the present study, the chromosomal mechanisms of nucleolar dominance were analyzed in the hybrid lineage Piaupara, which resulted from crossing the Leporinus macrocephalus female (Piau double dagger u) and L. elongatus ...
Three-dimensional porosity characterization in carbon/glass fiber epoxy hybrid composites
(2019-10-01)
The main objective of this study is to analyze the effect of the stacking sequence of glass/carbon-reinforced hybrid composites on the impregnation quality and on the formation of voids. This was achieved by creating a ...
Mode I and mode II delamination of carbon/glass/epoxy hybrid composite: A statistics-based analysis
(2021-01-01)
The delamination of a carbon/glass/epoxy hybrid composite was studied experimentally to analyze the effect of reinforcement heterogeneity on data dispersion. A statistical approach was applied to evaluate the effect of the ...
OBTAINMENT OF HYBRID COMPOSITES BASED ON HYDROGEL AND PORTLAND CEMENT
(Soc Brasileira Quimica, 2016-02-01)
In this study, a novel hybrid composite based on biodegradable hydrogel and Portland cement with promising technological properties was reported. In the first step, a full 2(3) with central point factorial design was ...
Chitosan/(ureasil-PEO hybrid) blend for drug delivery
(Springer, 2014-11-01)
The effect of chitosan addition on the structure and drug release properties of ureasil-polyethylene oxide (U-PEO) hybrid materials was examined. The hybrids and the blends were prepared by the sol-gel route and their ...
Occurrence of serrassalmidae hybrid fish in the amazon river basin, Brazil
(2019-01-01)
This study reports a case of occurrence of hybrid fish in the Amazon River basin, Brazil and attentive on to possible risks promoted with from crossbreeding between two species on local biodiversity. The specimen was ...
A simple geometrical path towards hybrid orbitals
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2014-11-01)
It is shown that the standard sp(n) hybrid orbitals are orthogonal orbitals that minimize the total quadratic spread. This is done in a concise way that may improve the understanding of hybrid orbitals. The fact that ...
The influence of carbon-glass/epoxy hybrid composite under mode I fatigue loading: Physical-based characterization
(2022-04-15)
The aim of this study was to characterize the mechanical behavior of a carbon-glass/epoxy hybrid composite under cyclic loading and following physical-based interpretation for mode I delamination modeling. The hybrid ...
Bacterial cellulose-silica organic-inorganic hybrids
(Springer, 2008-06-01)
Bacterial cellulose (BC) hydrated membranes present nanometric reticulated structure that can be used as a template in the preparation of new organic-inorganic hybrids. BC-silica hybrids were prepared from BC membranes and ...
Male sterility induced by the chemical hybridizing agent clofencet on wheat, Triticum aestivum and T. turgidum var. durum
(Pontificia Universidad Católica de Chile. Facultad de Agronomía e Ingeniería Forestal, 2009)
