A~~~-~erni~ Asiatic of B in synthetic melts of hapl~~tic composition have been measured by the diffusion couple technique at 1 atm between 1200-1600°C. The compositional profiles were measured by ion microprobe and modelled using the Boltzmann-Matano formalism to retrieve compositionally dependent interdiffision coefficients. At the experimental conditions, &OS is found to exchange primarily wi...

in order to investigate deformation history preserved in the calcite twins in the hinterland of zagros, several samples have been collected from calcschists of the paleozoic sargaz complex in the faryab area, se iran. these samples are related to f1-recumbent folding and thrust shear zones. the twin width is about 1 and 3.8 µm (thin-twin regime); the twin strain amounts 5 and 10%; twin intensit...

The Puy-les-Vignes W deposit, located in the northwestern French Massif Central (FMC), is a rare occurrence of wolframite-mineralized hydrothermal breccia pipe hosted high-grade metamorphic gneisses. We present an integrated study this deposit aiming to characterize ore-forming system link with Variscan late-orogenic evolution FMC. Based on set representative samples from host rocks and mineral...

Abstract. The origin of large miarolitic (also known as “chamber”) pegmatites is not fully understood although they may have great economic value. formation cavities in magmatic bodies related to melt degassing and gas or fluid flow through partially solidified magma. In this paper, the Volyn pegmatite field, located Palaeoproterozoic Korosten anorthosite–mangerite–charnockite–granite (AMCG) co...

An intrusion response system is charged with minimizing any losses caused by intrusion. It remains ineffective if the response to the intrusion does not bring the timely and adequate corrections required by the victim system. This paper proposes a new intrusion response system based on contextual fuzzy cognitive map. In this intrusion response system framework, a new ontology is defined based u...

background: there is no conclusive evidence on the effect of orthodontic force application on dental pulp tissue. the aim of this study was to compare early and delayed histological effects of intrusive forces on dental pulp of adolescents and adults. materials and methods: patients referred to the department of orthodontics of mashhad university of medical sciences participated in this study. ...

When carrying out compressive tests on rock specimens, a stress plateau is typically attained following peak strength within strain range few times larger than the at strength. This level commonly known as residual A large database of these granitic specimens has been compiled and analyzed in detail with aim improving understanding this type rock. It observed that physical scale does not signif...

Due to the rapid growth of networked computer resources and the increasing importance of related applications, intrusions which threaten the infrastructure of these applications have are critical problems. In recent years, several intrusion detection systems designed to identify and detect possible intrusion behaviors. In this work, an intrusion detection model is proposed to for building an in...
