Three series of new pyrimidine derivatives were synthesized and their antifungal activities were evaluated in vitro against fourteen phytopathogenic fungi. The results indicated that most of the synthesized compounds possessed fungicidal activities and some of them are more potent than the control fungicides. Preliminary SAR was also discussed.

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...

The potential of storing greenhouse gases in geological formations in the northeast portion of the Williston Basin is being investigated by researchers involved in the IEA Weyburn CO2 Monitoring and Storage Project. This project is linked to a CO2 miscible flood EOR program operated by EnCana Corporation in the Weyburn Midale Pool of southeastern Saskatchewan. A major component of the project i...

To solve the problem of communication delays and topology changes achieve a high-precision formation configuration control index in flight SAR (synthetic aperture radar) satellite formations, this paper studies consistency cooperative attitude orbit coupling for formations under constraints. First, establishes relative motion state error equation formations. Considering capacity constraints act...

The Imagery Exploitation System/Balanced Technology Initiative (IES/BTl) inputs synthetic aperture radar (SAR) imagery and outputs probabilistically ranked interpretations of the presence and location of military force membership, organiza­ tion, and expected ground formations. There are also probabilistic models of underlying terrain types from a tactical perspective that provide evidence supp...

This contribution determines suitable fingerprinting properties for sediment source discrimination within theAmrovan and Atary catchments in Semnan Province, Iran. These catchments are representative of a range of geology formations and should therefore provide a meaningful basis for a general assessment of the degree of sediment source discrimination afforded by a range of fingerprint properti...

We present the capabilities of low-frequency radar systems to sound the subsurface for a site located in south-central Egypt, the Bir Safsaf region. This site was already intensively studied since the SIR-A and SIR-B orbital radars revealed buried paleodrainage channels. Our approach is based on the coupling between two complementary radar techniques: the orbital synthetic aperture radar (SAR) ...

Introduction: Recent researches are shedding new lights on the evolution of Valles Marineris and neighboring chaotic terrain and outflow channels. For example , Chapman and Tanaka [1] proposed a hypothesis with an emphasis on magma-ice interactions for the formation of chasmata, interior deposits, chaotic terrain , outflow channels, and surface materials. Terrestrial analog studies are useful i...

in this paper, a new formula is applied for the calculation of gravity anomalies from a cylinder model representing a geological body. compared to conventional methods, this new development allows the cylinder to be freely oriented in space. 38 gravity forward models are produced each of which anomaly attributes are calculated. then a linear relationship is established between attributes and so...

New age data from Sr isotope analysis and both planktonic foraminifera and nannofossils are presented and discussed here for the Upper Eocene–Upper Miocene sedimentary rocks of the Değirmenlik (Kythrea) Group. New dating is also given of some Cretaceous and Pliocene sediments. In a revised stratigraphy the Değirmenlik (Kythrea) Group is divided into ten formations. Different Upper Miocene forma...
