Let $$\mathrm {Mod}(S_g)$$ denote the mapping class group of closed orientable surface $$S_g$$ genus $$g\ge 2$$ . Given a finite subgroup H , let {Fix}(H)$$ set fixed points induced by action on Teichmüller space {Teich}(S_g)$$ When is cyclic with $$|H| \ge 3$$ we show that admits decomposition as product two-dimensional strips at least one which bounded width. For an arbitrary generator order ...

Late Neoproterozoic- Early Cambrian schists exposed in southwest of Zanjan in northwest Iran.  Intrusion of Tertiary Korramdaragh monzogranite body within these schists have caused crystallization of porphyroblasts of hexagonal cordierite with cyclic radial sixling twin structure.  Hexagonal cordierite consists of six optically sectors.   Under microscope with crossed polarized, all of the sect...

Tohoku University, Japan is developing a new hand-held land mine detection dual-sensor (ALIS) which is equipped with a metal detector and a GPR. ALIS is equipped with a sensor tracking system, which can record the GPR and Metal detector signal with its location. The Migration processing drastically increases the quality of the imaging of the buried objects.Evaluation test of ALIS has been condu...
