Many polymorphisms exist in field bindweed (Convolvulus arvensis L.) populations. These differences that appear especially in their flower and leaf cause to different biotypes of this weed that are different in view of dry weight, rate- and flowering period. This research was accomplished during 2005 to 2006 at Weed Research Department, Iranian Plant Protection Research Institute for identifica...

Furthermore, texture analysis within the fibres may give additional information. MORPHOMETRY OF FLAT CIRCULAR DISCS G. Vrensen, J. Van der Want and J. Cornelisse Department for Morpho...

Microscopic image analysis of blood smear plays a very important role in characterization of erythrocytes in screening of malaria parasites. The characteristics feature of erythrocyte changes due to malaria parasite infection. The microscopic features of the erythrocyte include morphology, intensity and texture. In this paper, the different features used to differentiate the noninfected and mal...

Tomato Analyzer measures morphological and color attributes via image analysis in an objective, highthroughput, and semiautomatic manner. This software allows for reproducible quantification of phenotypic data that previously were done by hand or visual analysis. The new version has improved the accuracy of all measurements and reduced the need to make timeconsuming manual adjustments. In this ...

A one-dimensional high-symmetry growing surface in presence of step-edge barriers is studied numerically and analytically, through a discrete /continuous model which neglects thermal detachment from steps. The morphology of the film at different times and/or different sizes of the sample is analyzed in the overall range of possible step-edge barriers: for a small barrier, we have a strong up-do...

We report on the fabrication and optical transmission studies of thin three-dimensional photonic crystals of high-dielectric ZnS-core and low-dielectric SiO2-shell colloidal particles. These samples were fabricated using a vertical controlled drying method. The spectral position and width of a stopgap depend on the core-to-shell ratio, in a manner consistent with numerical calculations. Both ex...

Elaeagnus angustifolia L. is a Eurasian tree that has become naturalized and has various ecological, medicinal and economical uses. In this study, a combination of morphological traits and RAPD markers were used to study the presence or absence of an association between genetic variation and morphological features among five populations of E. angustifolia collected from the East Azarbaijan of I...
