arghash – ghasem-abad area in ne iran is located in the rim of the sabzevar structural zone. tertiary outcrops include granite and quartz monzodiorite porphyry associated with dacite and andesite volcanic rocks. in the study area, quartz gabbro and quartz monzodiorite dykes intruded the older rocks. granite and volcanic rocks host au-sb-bearing quartz-calcite veins. mineralized veins are mainly...

Using a new dataset, this paper presents new evidence on inequality in Latin America for the 19th century and studies the effects of factor endowments and trade on inequality. Recent research has highlighted the link between the colonial origins of inequality and its persistence in Latin America. We find that inequality varied substantially throughout the century a...

We report on a research effort aiming at the development of an acoustic bird activity detector (ABAD), which plays an important role for automating traditional biodiversity assessment studies – presently performed by human experts. The proposed on-line ABAD is considered an integral part of an automated system for acoustic identification of bird species, which is currently under development. In...

A topological duality for monadic n-valued Lukasiewicz algebras introduced by M. Abad (Abad, M.: Estructuras cíclica y monádica de un álgebra de Lukasiewicz nvalente. Notas de Lógica Matemática 36. Instituto de Matemática. Universidad Nacional del Sur, 1988) is determined. When restricted to the category of Q-distributive lattices and Q-homomorphims, it coincides with the duality obtained by R....

In this presentation questions are raised about a melt-restite unmixing model proposed by Barton and Sidle (1994) for the myrmekite-bearing Waldoboro granite complex along the southeastern coast of Maine (USA). This complex consists mostly of granite/granodiorite gneiss and granite, but smaller masses of quartz diorite, aplite, pegmatite, leucogranite, tourmaline granite, and granite porphyry o...

It is well established that the intracellular accumulation of Aβ (amyloid β-peptide) is associated with AD (Alzheimer's disease) and that this accumulation is toxic to neurons. The precise mechanism by which this toxicity occurs is not well understood; however, identifying the causes of this toxicity is an essential step towards developing treatments for AD. One intracellular location where the...

Emanation of radon ( 222 Rn) from granite countertops was measured using continuous and integrating radon monitors, and in air collected from encapsulated pieces of the countertops. A majority of the countertops emitted a measurable amount of radon. Although the granites contained the precursors, no thoron ( 220 Rn) emanation was detected. Gamma-ray spectroscopy was used to determine amounts of...

the study area is a part of cenozoic magmatic belt of central iran, which is located in the west of yazd porovince. contact metamorphism and skarn occurred in conglomerate part of sngestan formation. the oligocene intrusion bodies of ali-abad-darreh zereshk are leucocerate and have the chemical composition of granite to granodiorite with calc-alkaline affinity from volcanic arc geological setti...
