High Resolution Microscopy

Oxide phases having the hollandite structure have been identified in multiphase ceramic waste forms being developed for radioactive waste disposal. High resolution studies of phases in the waste forms described in Ref. [2] were initiated to examine them for fine scale structural differences compared to natural mineral analogs. Two hollandites were studied: a (Ba,Cs,K)-titan-ate with minor elements in solution that is produced in the waste forms, and a synthesized BaAl2Ti6O16 phase containing ∼ 4.7 wt% Cs2O. Both materials were consolidated by hot pressing at temperatures above 1100°C. Samples for high resolution microscopy were prepared both by ion-milling (7kV argon ions) and by crushing and dispersing the fragments on holey carbon substrates. The high resolution studies were performed in a JEM 200CX/SEG operating at 200kV.

The scenes in the trailer shown are all sorts of interesting and prominent scenesto attract the attention of potential viewers and be able to describe the entire contents of the movie without giving too much information. The trailer was created to promote theatrical release of the movie and the movie trailer was a clip containing all the parts of the advertised movie, shown before other movie screenings in the cinema, and aimed for the audience to come to watch. The best way to teach English is to use interesting material, appropriate teaching methods, the use of technology that can be one of the important and effective support tools. Meta-analysis is essentially a synthesis of a topic taken from several research reports. Based on the synthesis is drawn conclusions about the topic under study. This research uses some similar research results as basic data in conducting studies and conclusions. From the same five studies, it is concluded that Movie Trailer is effective as a learning medium because it can improve understanding in English learning.

Migmatitic Gneiss

The section between Tal to Talekhu of Manang District lacks the detailed geological study. The geological mapping in the scale of 1:50,000 followed by the preparation of geological cross-section and lithostratigraphic column has been done in the present study. The studied area lies partially in the Higher Himalayan Crystalline and the Tibetan Tethys Sequence. The units of the Higher Himalayan Group from Tal to Talekhu consists mainly of vigorous to faintly calcareous gneiss, migmatitic gneiss, quartzite, granite, etc. They are named as the Calc. Silicate Gneiss and Paragneiss and the Orthogneiss and Granite units. The lowermost part of the Tibetan Tethys consisted of metamorphosed calcareous rocks containing silicates and feldspar, so this unit is termed as the Marble and Calc. Gneiss. The section is about 9 km in thickness and is highly deformed with presence of igneous rocks at many places.
