"We can find many seeds of crystallography in Japanese culture. Most of the family crests have symmetry elements such as rotation axes and mirror symmetry elements. Sekka-zue, a picture book of 86 kinds of crystals of snow, was made by Toshitura Doi, who is a feudal lord in Edo-period and he observed snow using a microscope in nineteenth century. In recent years, people enjoy to make crystal structures, polyhedrons, carbon nanotube, quasicrystal etc. by origami, the art of folding paper [1]. In the field of science, the Japanese crystallography has contributed to explore culture and art. An excellent example is unveiling the original color of Japanese painting "Red and White Plum Blossoms" by Korin Ogata [2]. Prof. Izumi Nakai (Tokyo University of Science) developed an X-ray fluorescence analyzer and an X-ray powder diffractometer designated to the investigation of cultural and art works and had succeeded in reproducing the silver-colored waves through computer graphics after X-ray analyses of crystals on the painting. The scientific approach by Prof. Nakai et al. unveiled the mystery of cultural heritage of ancient near east, ancient Egypt etc. and is being to contribute to insight into the history of human culture. [1] An event to enjoy making crystals by origami is under contemplation. [2] The symposium ""Crystallography which revives heritages"" was held on February 16, 2014 at Atami in Japan."

This study aimed to investigate the Japanese Diaspora in the 17th century into Southeast Asia. This article   discussed critically the  motives, process, and the effect of Japanese diaspora in the Southeast Asia. Reseacher utilized historical method with descriptive approach. The process being performed namely heuristics, critism, interpretation, and historiography. Japanese history regarding abroad migration is an interesting issue between scholars who studied migration, anthropology, and minority studies over the decades. Edo period in Japan is one of the most studied field for many scholars for Japanese studies, since it shaped the characteristic of Japanese culture until today. Trade of Japan is significant part of its economical development since the pre-modern era. In the 17th century, Japan established a solid trade network with Southeast Asia regions, namely Siam, Malacca,  Cambodia, Vietnam and Manila. The emerge of maritime trade with Southeast Asia encouraged Japanese merchants to travel and create settlements in some regions. The Japanese diaspora was encouraged with vermillion seal trade which allowed them to do journey overseas and settled in some places, which eventually increased the number of Japanese merchants in the Southeast Asia. However, after the Sakoku policy there was restriction of trade relation ehich prohibited overseas maritime trade, except for China and Dutch. Sakoku policy caused Japanese merchants who stayed overseas could not return for many years, then they settled themselves as Japanese communities known as Nihon Machi in some places within Southeast Asia. History of early modern Japan between the 16th and 19th century provides a broader narratives of global history as it was surrounded by intense global interaction.

A 42-year-old female presented in Neurology Department of Sir Salimullah Medical College with gradually worsening difficulty in talking and eating for the last four months. Examination revealed dystonic tongue, macerated lips due to continuous drooling of saliva and aspirated lungs. She had no history of taking antiparkinsonian, neuroleptics or any other drugs causing dystonia. Chest X-ray revealed aspiration pneumonia corrected later by antibiotics. She was treated with botulinum toxin type-A. Twenty units of toxin was injected in six sites of the tongue. The dystonic tongue became normal by 24 hours. Subsequent 16 weeks follow up showed very good result and the patient now can talk and eat normally. (J Bangladesh Coll Phys Surg 2006; 24: 75-78)

Non Destructive

AbstractX-ray topography provides a non-destructive method of mapping point-by-point variations in orientation and reflecting power within crystals. The discovery, made by several workers independently, that in nearly perfect crystals it was possible to detect individual dislocations by X-ray diffraction contrast started an epoch of rapid exploitation of X-ray topography as a new, general method for assessing crystal perfection. Another discovery, that of X-ray Pendellösung, led to important theoretical developments in X-ray diffraction theory and to a new and precise method for measuring structure factors on an absolute scale. Other highlights picked out for mention are studies of Frank-Read dislocation sources, the discovery of long dislocation helices and lines of coaxial dislocation loops in aluminium, of internal magnetic domain structures in Fe-3 wt.% Si, and of stacking faults in silicon and natural diamonds.

The Web

When facing the persistent conundrum of evangelical missions in Japan, one pervasive, though largely hidden, factor emerges in the resistance of the Japanese to the gospel: the web-like interconnection of worldview assumptions collectively known as Nihonkyo (“Japanism“), as distinct from Japanese culture per se. Developing sociologically in the Edo Period and ideologically in the Meiji Period, the fabrication of Nihonkyo changed attitudes toward cultural elements such that a nation once very open to the gospel has become very closed. Principles of the problem and its discernment are widely applicable.

A 19 years old married female presented with severe upper abdominal pain, repeated vomiting having history of swallowing a knife 7 months ago was admitted in Mordern Clinic and Diagnostic center, Joypurhat, Bangladesh. USG abdomen & X-ray (fig-1) abdomen were done when presence of a large foreign body (knife fig-3) in abdomen was made which latter on confirmed by Endoscopy of upper GIT (fig-2). Surprisingly the patient kept it in her abdomen for 7 months without any symptoms until the symptoms got worse and compelled her to seek medical help. The knife was removed by laparotomy, gastrotomy with uneventful recovery.Bangladesh Journal of Medical Science Vol.14(2) 2015 p.210-212

AbstractThe crystalch emistry and crystal structure of naturalky anite crystals from the Eclogitic Micaschists Complex of the Sesia-Lanzo Zone, Western Italian Alps, have been investigated by means of optical microscopy, wavelength dispersive X-ray microanalysis, and single-crystal X-ray diffraction. The association of kyanite + garnet + phengitic-mica + chloritoid suggests that the eclogite-facies stages occurred at P ≤ 2.1 GPa and T ≤ 650ºC. Kyanite grains are large (cm-sized) porphyroblasts grown dynamically during one of the deformational events related to the subduction of the Austroalpine continentalcr ust. Under the polarizing microscope, kyanite grains show almost homogeneous cores, whereas rims are sometimes symplectitic aggregates of quartz and kyanite, confirming at least two stages of growth most likely related to the multistage deformational history of these rocks. Chemical analysis shows that Fe3+ is the major substituting cation for Al3+, ranging between 0.038 and 0.067 a.p.f.u.The single-crystal X-ray diffraction investigation of the kyanites shows severely textured patterns on the (h0l)*-plane. Such evidence is not observed in the unwarped diffraction patterns on (0kl)* and (hk0)*. The most significant difference between the structuralp arameters refined in this study, with respect to those of previously published unstrained gem-quality crystals, concerns the displacement parameters. The anisotropic displacement ellipsoids of all the atomic sites are significantly larger than those previously described, and systematically oriented with the largest elliptical section almost perpendicular to [010]. The larger ellipsoids in the kyanite crystal investigated here reflect the displacement of the centre of gravity of the electron distribution, rather than an anomalous atomic thermal motion. The magnitude and orientation of the displacement parameters and the textured/strained diffraction pattern may be the result of two combined effects: (1) that the kyanite crystals are actually composed of several blocks; (2) the crystals are affected by a pervasive residual strain, as a result of tectonometamorphic plastic deformations and re-crystallization.

Insight Into

<p>Stromatolites, i.e. macroscopically laminated carbonate rocks formed by diverse microbial communities, are particularly emblematic geobiological materials since they are the oldest evidence of life-mineral interactions, dated up to 3.5 Gyrs ago.  They are found throughout the history of the Earth and have received strong attention because they provide precious information about microbial paleobiodiversity and paleoenvironments. However, while this information is interpreted based on our knowledge about modern analogs, the latter remains very incomplete. Here, we studied recently discovered modern stromatolites from Mari Ermi<sup>1</sup>, a coastal pond in Western Sardinia, that seasonally experience severe evaporation and broad salinity variations. For this purpose, we explored the mineralogical composition of these unique sedimentary archives and its spatial variations in order to gain better insight into how mineral phases record the conditions and processes of their formation. We investigated the heterogeneous distribution of minerals using quantitative X-ray chemical maps provided by energy dispersive x-ray spectrometry analyses coupled with scanning electron microscopy (SEM-EDXS). Hyperspectral maps were analyzed using an innovative data treatment method <sup>2</sup> allowing phase recognition within the complex mineral mixtures and solid solutions encountered. This method provided quantitative data on spatial distribution, modal content and associated calculated unit formulas for each identified mineral and phase with a hundred nanometer resolution. Based on these results, we will discuss the origin of the laminations in the stromatolites.</p><p>Reference:</p><p>1. Saint Martin, J.-P. & Saint Martin, S.
