Correlative fractography: Combining scanning electron microscopy and light microscopes for qualitative and quantitative analysis of fracture surfaces
(2013-04-01)
Correlative fractography is a new expression proposed here to describe a new method for the association between scanning electron microscopy (SEM) and light microscopy (LM) for the qualitative and quantitative analysis of ...
Silk formation mechanisms in the larval salivary glands of Apis mellifera (Hymenoptera : Apidae)
(Indian Academy Sciences, 2003-12-01)
The mechanism of silk formation in Apis mellifera salivary glands, during the 5th instar, was studied. Larval salivary glands were dissected and prepared for light and polarized light microscopy, as well as for scanning ...
Correlative light-electron fractography of interlaminar fracture in a carbon-epoxy composite
(Microscopy and Microanalysis, 2015-10-30)
This work evaluates the use of light microscopes (LMs) as a tool for interlaminar fracture of polymer composite investigation with the aid of correlative fractography. Correlative fractography consists of an association ...
Correlative light-electron fractography for fatigue striations characterization in metallic alloys
(2013-09-01)
The correlative light-electron fractography technique combines correlative microscopy concepts to the extended depth-from-focus reconstruction method, associating the reliable topographic information of 3-D maps from light ...
Methods for glomerular quantification in dogs: A comparative studyMetodologias para quantificação glomerular em cães: Um estudo comparativo
(2019-01-01)
It was evaluated the different methodologies for glomerular enumeration described in the literature in a quantitative, double-blind study on the number of glomeruli present in kidney biopsy specimens obtained using a ...
FINE-STRUCTURE AND MORPHOGENESIS OF THE MICROPYLE APPARATUS IN BEES EGGS
(Inst Histol Embriol-conicet, 1995-08-01)
The present paper deals with the description of the formation of the micropylar apparatus in some species of Apidae bees. The features of the cells located in the anterior pole of the oocyte chamber are described at light ...
Ultrastructure of the intramandibular gland of workers and queens of the stingless bee, Melipona quadrifasciata
(Univ Arizona, 2011-08-24)
The intramandibular glands of workers and queens of Melipona quadrifasciata Lepeletier (Hymenoptera: Apidae), at different ages and from different functional groups, were studied using light and transmission electron ...
