An Anthemion stele from Phrygia

A WARRIOR-RULER STELE FROM SRi K~ETRA, PYU, BURMA

Beginning to construct a chronology of Pyu sculpture is exceedingly difficult. An extraordinary stone stele, discovered at Sri ~etra in the 1970s presents a new dimension to our understanding of the origins of the Pyu sculptural style. It invites comparison with Indian prototypes of the early centuries AD from Andhra Pradesh, especially the low relief panels favoured for stupa decoration at Nag...

Occurrence of acetylcholine-hydrolyzing activity at the stele-cortex interface.

Acetylcholine (ACh) is a chemical transmitter serving to propagate an electrical perturbation across the synaptic junctions of animals. ACh and AChE have previously been demonstrated to occur in plants. In this work, we detected AChE at the interface between stele and cortex of the mesocotyl of Zea mays by measuring hydrolysis of acetylthiocholine and by liberation of labeled acetate from [1-(1...

Recognition-Based Segmentation of Nom Characters from Body Text Regions of Stele Images Using Area Voronoi Diagram

Segmentation of Nom characters from body text regions of stele images is a challenging problem due to the confusing spatial distribution of the connected components composing these characters. In this paper, for each vertical text line, area Voronoi diagram is employed to represent the neighborhood of the connected components and Voronoi edges are used as nonlinear segmentation hypotheses. Char...

The limitations of molecular markers in phylogenetic reconstruction: the case of Centaurea section Phrygia (Compositae)

a paradigm shift away from method-wise teaching to strategy-wise teaching: an investigation of reconstructive strategy versus communicative strategy

چکیده: هدف اصلی این مطالعه ی توصیفی تحقیقی در حقیقت تلاشی پساروش-گرا به منظور رسیدن به نتیجه ای منطقی در انتخاب مناسبترین راهکار آموزشی بر گرفته از چارچوب راهبردی مطرح شده توسط والدمر مارتن بوده که به بهترین شکل سازگار و مناسب با سامانه ی آموزشی ایران باشد. از این رو، دو راهکار آموزشی، راهکار ارتباطی و راهکار بازساختی، برای تحقیق و بررسی انتخاب شدند. صریحاً اینکه، در راستای هدف اصلی این پژوهش، ر...
