‘romanticism’ and ‘romantic’ are among the most controversial terms in literature. most readers, when encountering these words, would think of the well-known period of romanticism of the first three decades of the nineteenth century and the great six english poets known as ‘the big six’ of this period. however, romanticism does not belong to certain artists in a special period; one may seek ele...
This work explores the multi-element capabilities of inductively coupled plasma-mass spectrometry with collision/reaction cell technology (CCT-ICP-MS) for the simultaneous determination of both spectrally interfered and non-interfered nuclides in wine samples using a single set of experimental conditions. The influence of the cell gas type (i.e. He, He+H2 and He+NH3), cell gas flow rate and sam...
what has been discussed here has been a study of international immigration law. this branch of law has not been a major player in the field of international law. no collective law exists, and no codification has been carried out as yet. however, the need for such a set of laws has forced the international community to pay more attention to this issue. the need for a better life in the so-call...
Orthopyroxene (Opx) was present during a significant portion of crystallisation of the lunar magma ocean, but its influence on co-existing melt trace element contents is not well quantified. We performed high-pressure (P, 1.1 to 3.2 GPa), high-temperature (T, 1400 to 1600 °C) experiments on synthetic Fe-rich compositions at reducing conditions relevant to the lunar mantle to constrain trace ele...
abstract this study aimed at investigating the possible relationship between self-assessment in writing and self-regulation of iranian efl learners. the main purpose of the study was not only to report and inform about this relationship, but also to investigate and find practical outcomes of the incorporation of self-assessment in writing, such as improving writing skill. the research was carr...
We investigate the coupling between H, minor, trace, and ultra-trace element incorporations in 17 olivines from ten different locations covering various petrological origins: magmatic, hydrothermal, mantle-derived context. Concentrations major are determined by micro X-ray fluorescence. Minor, elements laser ablation inductively coupled plasma mass spectrometry. Hydrogen concentrations quantifi...
background: within the context of developing techniques to facilitate the diagnosis of the thyroid diseases, the elemental composition of pathological thyroid tissue (neoplastic and non-neoplastic) was investigated by proton induced x-ray emission. the pixe has been widely used as a sensitive technique for trace elemental analysis in both biological and medical fields. materials and methods: th...
This study investigates petrology and major, minor, and rare earth elements geochemistry of East Iranian Eocene–Oligocene volcanic rocks in Sistan suture zone, to examine their petrogenesis and magma evolution. The volcanic rocks include andesite, trachy-andesite, dacite and rhyolite. These calc-alkaline rocks of high-K series are enriched in Large Ion Lithophile Elements of Rb and Ba a...
