in order to assess the satellite data for soil investigation, aster digital data 20 june 2006, field study and phisiochemical properties of soil, were analyzed. all landcover classes including soils are classified based onmorphological and physico-chemical characteristics. images were geocorrected and photomorphic units were selected based upon visual interpretation and sampling in study area. ...

This study was aimed at understanding the role of sulfolipids in salt tolerance mechanisms of the halophytes Aster tripolium L., Compositae, and Sesuvium portulacastrum L., Aizoaceae, and of the glycophyte Arabidopsis thaliana (L.) Heynh., Brassicaceae. In Aster and Sesuvium the sulfolipid contents increased significantly under salt stress conditions (517 mM or 864 mM). In Arabidopsis, changes ...

ASTER — Audio System For Technical Readings — is a computing system that produces audio renderings from the same (L)TEX source used to produce the printed document. Raman (1992) described our preliminary work on this project. At the time, correct handling of user-defined (L)TEX macros was described as one of the key issues in building a fully extensible audio rendering system. ASTER (Raman, 199...

Suitability of ASTER satellite data for estimating biomass and LAI for mountain birch forests was investigated. The field data consisted of 124 plots surveyed in northernmost Finland in July 2004. The statistical relationships between the field measurements and ASTER reflectances were modelled using canonical correlation analysis (CCA) and reduced major axis (RMA) regression. The models were ap...

A new species of Aster (Asteraceae) from China, Aster shennongjiaensis W. P. Li et Z. G. Zhang, is described and its morphology and karyotype illustrated. Aster shennongjiaensis is apparently endangered, presently known only from one small population in bamboo forests of Shennongjia Reserve in central China. On a morphological basis, the closest species to A. shennongjiaensis is A. lasiocladus ...

BACKGROUND Aster tataricus L. f. is used as a traditional Chinese drug to relieve cough and asthma symptoms and to eliminate phlegm. However, Aster tataricus L. f. possesses toxicity, and little systematic research has been conducted on its toxic effects in the laboratory. METHODS AND MATERIALS The acute group was administered 75% alcohol extract of Aster tataricus L. f. in a single dose. A s...

There is a need to automate terrain feature mapping so that to make the process more objective and less time consuming by using proper feature extraction techniques. The objective of this study was the use of object-oriented image analysis methods for the automatic extraction of alluvial fan terrain units. The study area was located in the Death Valley, Nevada, USA. The data used included an AS...

Abstract Quaternary placer deposits are becoming increasingly important. Remote sensing is a very powerful tool in discriminating altered areas related to intrusion deposits, which has significantly reduced the cost and time of exploration. In this study, to identify iron-bearing alluvial zones within the 1:100000 sheet of Hamedan, satellite image processing techniques such as band ratio (BR),...

This paper introduces the Aster distributed composition-based programming system that is aimed at easing the development of distributed runtime systems, customized to the application needs, in a Corba-based environment. Our approach is based on high-level customization: given the speci cation of application requirements using the Aster composition language, a distributed runtime system, customi...
