introduction: the cell surface glycoconjugate and extracellular matrix may mediate extracellular signals which decide the fate of the cells during tissue interactions. the proper development of cornea needs cellular interaction between surface epithelium, neural crest and developing lens. materials and methods: 50 pregnant rats were chosen and the embryos from pernatal day11-to 20 and postnatal...

Directional emission from a slit surrounded by rectangular grooves on the exit surface in a conducting plane is investigated. An electromagnetic boundaryvalue problem dealing with a slit surrounded by rectangular grooves on the exit surface in a conducting plane is rigourously solved based on the Fourier transform, eigenfunction expansion, and mode-matching method. The radiation pattern from th...

Verfahren erzielt wird. Inspection of Specular Surfaces with Inverse Patterns The application of inverse patterns to fast and robust mirror surface evaluation is shown. In a well controlled environment, one observes via the mirror surface a screen onto which a well-defined pattern is displayed. Evaluation of the deflected pattern is used to determine surface defects of the object under test. In...

This paper presents a technique for integrating multiple visual features for tracking moving objects. Our proposed method consists of observation (pattern-matching) units and prediction units, which form a ladder structure. The major feature of our proposed method is that each of the observation units with different pattern matching algorithms is executed step-by-step to innovate the state vect...

Indian Ocean is known as a source of moisture for southeast of Iran due to summer precipitation. In this study, in order to investigate the role of SST of Indian Ocean, and the convergence and divergence fields in the precipitation of southeast of Iran, precipitation data of five synoptic stations were used during 2000-2010, including Iranshahr, Khash, ChahBahar, Zabul, and Saravan. To investig...
