Intelligent microscopic approach for identification and recognition of citrus deformities

Microscopy research and technique (Print), 2019
Plant diseases are accountable for economic losses in an agricultural country. The manual process of plant diseases diagnosis is a key challenge from last one decade; therefore, researchers in this area introduced automated systems. In this research work,

Identification of active spermatogenesis using a multiphoton microscope

Andrology, 2023
AbstractBackgroundThe sperm retrieval rate of microdissection testicular sperm extraction varies from 25% to 60%. Therefore, it is necessary to establish objective selection criteria for identifying seminiferous tubules with spermatozoa.ObjectivesOur aim was to develop a method for identifying spermatogenesis without sectioning testicular tissues ...

Immunoelectron Microscopic Identification of Human Parvovirus B19

Ultrastructural Pathology, 1994
A mildly macerated, hydropic fetus was delivered spontaneously at 25 weeks gestation by a multigravidous black mother. At autopsy, gross and microscopic evidence suggested fetal anemia, and excessive extramedullary erythroblastosis was present generally.

Microscopical identification of atmospheric particles

Fresenius' Zeitschrift f�r Analytische Chemie, 1976
The successful identification of particulate pollutants requires specialized tools and techniques for sampling, fractionation, manipulation and characterization. The integration of these techniques enables the microscopist to identify almost any single particle larger than 1 femtogram (10−15 g).

Printed source identification by microscopic images

2016 IEEE International Conference on Image Processing (ICIP), 2016
The research of printed source identification is generally processed by scanned images which are limited by the scanner resolution. The accuracy of source identification is also bound by this limitation. In this study, microscopic images are used for printed source identification based on its high magnification capability for detailed texture and ...

[Microscopic identification of Rhodiola henryi].

Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials, 2002
To study the microscipic characteristics of the rhizoma, root, stem, leaf and powder of Rhodiola henryi.By microscopic observation.The brown substance was always found in the rhizoma and root of Rhodiola henryi. There was a fiber ring in the cambium region of the stem, and some fiber bundles surrounded the pholem.

Electron Microscopic Identification of Autonomic Nerve Endings

Nature, 1966
THE endings of some autonomic axons, which are presumed to be either adrenergic or cholinergic in function, can be distinguished using the electron microscope by their different populations of vesicles. This was first pointed out by de Robertis and Pellegrino de Iraldi1. The cholinergic fibres, as in motor end-plates of skeletal muscle, contain uniform

Raman microscopic identification of gunshot residues

Journal of Raman Spectroscopy, 1998
Raman microscopy was used to identify unambiguously the anions of lead and barium in gunshot residues (ca. 5 μm in size) deposited on cellulosic substrates. It was found that most of the particles consist of mixtures of oxides, sulphate and carbonate (along with carbon).

Chenopod and Amaranth Pollen: Electron-Microscopic Identification

Science, 1967
Electron-microscopic criteria for distinguishing chenopod and amaranth pollen have been found in the number of minute holes and spinules, and especially in the ratio between them, which is < 1.5 in amaranths and > 1.6 in chenopods. Sixty-eight percent of total fossil pollen from a Classic Maya level (carbon-14 age 1380 ± 120 B.P.) in
