Introduction: Current interest in the origin of the more primitive components of Interplanetary Dust Particles (IDPs) has focused on the solid-state processing of IDP grains by the energetic ion component of space radiation [1,2,3]. Particular attention has been paid to radiation processing of IDP silicates, since space radiation effects are clearly evident in these phases [2]. The effects rang...

This study examined how motivation for learning English, the amount of contact with English, and  length  of  residence  in  the  target language area affects Korean graduate students’ English pragmatic skills. The study attempted to account for differential pragmatic development among 50  graduate-level  Korean  students  in  relation  to  individual  factors  mentioned  above.  The  data were...

In County Donegal, northwest Ireland, thousands of homes built with concrete blocks show an increasing degree severe structural defects attributed to high mica content in the aggregates. Consequently, problem is popularly known as “Mica Crisis”. this project four affected are investigated by microstructural and chemical analysis combined thermodynamic modelling. Apart from mica, aggregates cont...

Multipolarity remanence in greigite-bearing sediments has long been recognized, but the cause of this anomalous behavior is not well understood. Here, we use electron microscopic and magnetic analyses to investigate origin such multipolarity Miocene from Pannonian Basin (Hungary). We find a softening partial transformation iron sulfides magnetite pyrrhotite “single-polarity” “multi-polarity” sa...

Detailed magnetostratigraphic studies of Late Neogene siliciclastic sediments of the Awatere Group, South Island, New Zealand (41°45'S, 174°05'E) have revealed a wide range of palaeomagnetic behaviour. Examination of rock magnetic properties was undertaken using conventional palaeomagnetic techniques and thermomagnetic, X-ray diffraction and electron microprobe analyses. These analyses indicate...
