Morphometric analyzes support an understanding of the physical characteristics hydrographic basins and are commonly used to estimate hydrological variables. This work aims compare geomorphological time concentration (Tc) in two watersheds: upper part Jundiaí river (139.3 km2) Piraí (209 belonging basin, state São Paulo. To calculate Tc, empirical equations monitored data were applied. Applying ...

Morphometric analysis of the human cervical large motoneurons in the anterior horn was performed in 7 male cadavers with the help of an image-analyzer and the use of a new tissue preparation method which minimizes shrinkage. This method makes it possible to precisely evaluate the size of cervical motoneurons at each level. Our study revealed a difference in number, average area and total area o...

Fifty cytologically malignant, five suspicious, and 27 cytologically benign serous effusions were assessed morphometrically for differences in mean and outlying nuclear and cytoplasmic variables. Significant differences were found between benign and malignant specimens for all nuclear morphometric variables measured, the most significant being largest nuclear area and diameter. No significant d...

The number of gastrin-producing cells in biopsy specimens from the gastric and duodenal mucosae in 19 duodenal ulcer patients was quantitated using a morphometric method. The level of immunoreactive gastrin in a sample of fasting serum obtained at the time of the biopsy was measured by radioimmunoassay. The results show no significant difference when compared with those from a group of normal c...

the black-striped pipefish, syngnathus abaster, is a species of the syngnathidae family. this study provides data on the morphometric, meristic and genetic structuring of the caspian sea pipefish, syngnathus abaster. eight morphometric characteristics based on total length and five morphometric characteristics based on standard length were analyzed. a total of 50 specimens were collected in bra...

spotted amber ladybird, hippodamia variegata (goeze, 1777) (coleoptera: coccinellidae) is an important predator of aphids and some other insect pests. since shape and size variation may affect biological characteristics of an insect, multivariate analysis of shape variations in four geographically isolated populations of h. variegata (isfahan, shahrekord, shiraz, yasuj) was performed based on e...

Fifty cytologically malignant, five suspicious, and 27 cytologically benign serous effusions were assessed morphometrically for differences in mean and outlying nuclear and cytoplasmic variables. Significant differences were found between benign and malignant specimens for all nuclear morphometric variables measured, the most significant being largest nuclear area and diameter. No significant d...

Volume measurements were carried out on 19 brains from leucotomised schizophrenic patients and 20 age- and sex-matched controls using a stereological method. The volume of the total fixed brain, hemispheres, cortex, white matter, and central grey matter were all significantly reduced compared with controls. White matter and central grey structures were significantly reduced compared with a grou...

This study was designed to characterize morphometric sperm subpopulations in normozoospermic men by using different statistical methods and examining their suitability to classify correctly different sperm nuclear morphologies present in human ejaculates. Ejaculates from 21 normozoospermic men were collected for the study. After semen collection and analysis, samples were prepared for morphomet...
