The present study deals with the estimation of the advanced spaceborne thermal emission and reflection radiometer (ASTER) data for geological application. Visible, near-infrared and short wave infrared reflectance data (9 ASTER bands) have been processed and interpreted in framework of a mapping project concerning the western margin of the Kalahari desert. A methodology has been applied to appa...

Shuttle Radar Topographic Mission (SRTM) and ASTER Global Digital Elevation Model (GDEM) provide topographic data in a global scale which are freely available for users. The potential use of these datasets for many forestry applications is highly depending on the accuracy of the datasets. In this study, we evaluated the accuracy of SRTM and ASTER GDEM version 2 with high accuracy topographic da...

Anti-tubulin antibodies and confocal immunofluorescence microscopy were used to examine the organization and regulation of cytoplasmic and cortical microtubuies during the first cell cycle of fertilized Xenopus eggs. Appearance of microtubuies in the egg cortex temporally coincided with the outgrowth of the sperm aster. Microtubuies of the sperm aster first reached the animal cortex at 0.25, (t...

PREMISE OF THE STUDY Simple sequence repeat (SSR) markers were developed for Aster savatieri (Asteraceae) and the serpentine variety A. savatieri var. pygmaeus to re-evaluate their taxonomic status. METHODS AND RESULTS Using RNA-Seq data, 22 expressed sequence tag (EST)-SSR markers were developed. Polymorphisms were assessed in A. savatieri and in A. savatieri var. pygmaeus. The average numbe...

Methods for extracting mineralized alteration information using remote sensing images have recently become both efficient and cost-effective. Technology involving the extraction of based on multi-spectral data has been widely practiced effectively verified. In recent years, research fine mineral methods hyperspectral also rapidly developing. The Yulong copper belt is a porphyry located in China...

The current study presents the integration between field observations and remotely sensed data for detection extraction of geological structural features using Sentinel-2A Aster DEM images. area under investigation is represented by Neoproterozoic East African Orogeny encompassing a part Arabian Nubian Shield. All rock units studied belong to Late Cryogenian-Ediacaran periods that are divided i...

This paper examines the potential of ASTER data in mapping the geology of an arid area in Africa using spectral analysis techniques. Equipped with a relatively broad spectral range, fine spatial resolution, and a large number of bands, ASTER data are especially attractive to many geological researchers in Africa, due to their open availability and associated minimal costs for academic use. The ...

Global Digital Elevation Models (GDEM) are considered very attractive for current research and application areas due to their free and wide range accessibility. The ASTER Global Digital Elevation Model exhibits the highest spatial resolution data of all global DEMs and it is generated for almost the whole globe. Unfortunately, ASTER GDEM data include many artifacts and height errors that decrea...

Taxol blocks the migrations of the sperm and egg nuclei in fertilized eggs and induces asters in unfertilized eggs of the sea urchins Lytechinus variegatus and Arbacia punctulata. Video recordings of eggs inseminated in 10 microM taxol demonstrate that sperm incorporation and sperm tail motility are unaffected, that the sperm aster formed is unusually pronounced, and that the migration of the e...
