Axial CT images of mummies. Left column (A, C, E, G, I and K): the current Andong case with Congenital Diaphragmatic Hernia (CDH); Right column (B, D, F, H, J and L): Gangneung mummy case without CDH.

<p>(A) and (B) TV3 upper level. Ht, heart; RL, right lung; LL, left lung; asterisk, pericardial sac. (C) and (D) TV3 lower level. RL in (C) showed split pattern (a and b). Ht in (C) exhibited mediastinal shift to the left. (D) The similar structure is not seen at the same CT level of Gangneung mummy. (E) and (F) TV5 level. (E) Liver (Lv) is seen at the same level of heart (Ht). Mediastinal shift to the left side is very severe, comparing with normal CT in (F). (G) and (H) TV7 level. (G) Colon (Co) and Liver (Lv) is seen at the same level of heart (Ht). Mediastinal shift is still remarkable. (H) Colon is not observed. Liver (LV) begins to emerge. (I) and (J) TV 9 level. (I) Mainly intestine (Int) is visible. (J) Large liver (LV) could be seen at the same level of Gangneung mummy. (K) and (L) LV1 level. Intestine or other mummified abdominal organs fills the cavity in both CT images.</p

Dissection of the mummy.

<p>(A) Thoracic and abdominal cavities exposed. Pe, pericardium; Dph, diaphragm; Om, omentum; Pe, pericardium; LL, Left lung; RL, right lung. (B) Magnified image of right thoracic cavity. Parts of liver (Lv) and colon (Co) could be found within the right thoracic cavity. (C) A part of RL is turned back. Lv and Co are much clearly identified. The defect in diaphragm is indicated by arrow. (D) Lv is protruding into the diaphragmatic surface of RL that is therefore folded into anterior (RLA) and posterior parts (RLP). (E) View from cephalic to rostral. Bochdalek hernia (indicated by arrow) in Dph is observed. Lv protrudes through the hernia defect.</p

Coronal CT images of the current Andong mummy with Congenital Diaphragmatic Hernia.

<p>(A) Herniated liver (Lv) could be seen while diaphragm (Dph) is visible underneath. (B) Herniated organs stretching from abdominal to thoracic cavities could be clearly seen. Ht, heart; LL, lung. (C) and (D) Sagittal CT images of Andong mummy. (C) Diaphragm (Dph) is clearly seen between thoracic and abdominal cavity. (D) Herniated organs could be observed through the diaphragmatic defect (asterisk). AA, ascending aorta; DA, descending aorta; Abd A, abdominal aorta.</p

Examination of Andong mummy.

<p>(A) Removal of clothing. (B) and (C) Very well preserved human and cultural remains. (B) is hand; (C) is straw shoes. (D) The mummy examined in this study.</p

Si/Ge Double-Layered Nanotube Array as a Lithium Ion Battery Anode

Problems related to tremendous volume changes associated with cycling and the low electron conductivity and ion diffusivity of Si represent major obstacles to its use in high-capacity anodes for lithium ion batteries. We have developed a group IVA based nanotube heterostructure array, consisting of a high-capacity Si inner layer and a highly conductive Ge outer layer, to yield both favorable mechanics and kinetics in battery applications. This type of Si/Ge double-layered nanotube array electrode exhibits improved electrochemical performances over the analogous homogeneous Si system, including stable capacity retention (85% after 50 cycles) and doubled capacity at a 3<i>C</i> rate. These results stem from reduced maximum hoop strain in the nanotubes, supported by theoretical mechanics modeling, and lowered activation energy barrier for Li diffusion. This electrode technology creates opportunities in the development of group IVA nanotube heterostructures for next generation lithium ion batteries
