Abstract Geochemical and mineralogical investigations of the Lower Permian Kemmlitz rhyolite within NW-Saxonian Basin (Germany) associated lithophysae (high-temperature crystallization domains) as well agates were carried out to constrain genesis characteristics these volcanic rocks origin agate-bearing lithophysae. The rhyolitic composition are dominated by quartz, sanidine, orthoclase most li...

In 2015, Jack Davis and Sharon Stocker, while excavating the so-called “Tomb of a warrior with griffin”, discovered an agate seal extraordinarily detailed depiction combat scene. It shows armed sword only, bending over his adversary’s shield, grabbing him by crest helmet using it as leverage to render absolutely powerless. The article studies image on Pylos reflection early epic narrative. is s...

The possibility of using Brazilian stones in gamma high-dose dosimetry was investigated at IPEN using the optically stimulated luminescence (OSL) technique. Agate samples were studied in relation to their OSL dosimetric properties, in this work. The samples were irradiated at a Gamma-Cell system (Co). The calibration curves show a sublinear behavior between 50 Gy and 300 kGy, and the lower dete...

inger equation (TDSE). It uses the Crank–Nicholson scheme to propthen solving the resulting eigenproblem by expanding on agate the wavefunction forward in time and finite differences to some basis set. Examples of such techniques are the colloapproximate the derivative operators. The resulting sparse linear cation and Galerkin methods implemented via piecewise system is solved by the symmetric ...

Noncompliance in Antiplatelet Trials: The AGATE Trial Perspective To the Editor: Recent studies have highlighted the importance of patient compliance in clinical trials of antiplatelet therapy. The AGATE trial1 was designed as a head-to-head comparison of the antiplatelet properties of Aggrenox (a combination of aspirin and dipyridamole) versus aspirin alone in patients with a recent history of...
