For gold, the most promising elements for provenance are Platinum Group Elements (PGE), Sn, Te, Sb, Hg, Pb, but also high melting point elements, such as Ta and Nb. Small fragments of native Carpathian gold placer and primary were studied using Synchrotron Radiation X-Ray Fluorescence at ANKA synchrotron. The goal of the study was to identify the trace elements, especially Sn, Sb and Te. The me...

In this paper we present a timing-driven placer for standard-cell IC design. The placement algorithm follows the genetic paradigm. A t early generations, the search is biased toward solutions with superior tarning characteristics. As the algorithm starts converging toward generations with acceptable de lay properties, the objective is dynamically adjusted toward optimizing area and routability....

La década de 1970 evidenció una producción ideas y movilizaciones en torno a diversas temáticas la vida social, política, cultural. Feministas movimientos mujeres interpelaron fuertemente las construcciones género hegemónicas diseñadas su domesticidad. Las discusiones atravesaron el mundo cinematográfica. Laura Mulvey escribió 1975 emblemático texto Placer Visual cine narrativo, cuestionando lu...

This article lists a number of geological data on the conditions of formation of some major gold deposits in the conglomerates of the Earth's crust. We analyze the metallogenic, tectonic, stratigraphic and other factors controlling the formation of gold-bearing conglomerates in certain fields, such as the Witwatersrand (S. Africa) and Darwaz (Tajikistan). The following tectonic factors play the...
