Time-Dependent Behavior of Diatomaceous Earth under Triaxial Compression and Its Modeling

Autor: Takashi TAKEHARA, Kuniyuki MIYAZAKI, Yasuhide SAKAMOTO

Publikováno v: Journal of MMIJ, Vol 140, Iss 6, Pp 94-100 (2024)

In the geological disposal of radioactive waste, it is imperative to perform long-term assessments of the shielding efficacy and mechanical stability of the surrounding rock. Numerous investigations into the timedependent characteristics of various r

Changes of Coal Strength under Hydrostatic Pressure Caused by CO2 and N2 Injection

Autor: Takashi TAKEHARA, Yasuki OIKAWA, Takashi FUJII, Kuniyuki MIYAZAKI

Publikováno v: Journal of MMIJ, Vol 136, Iss 11, Pp 134-139 (2020)

A project of CO2 injection in the Ishikari coal basin (Yubari-shi, Hokkaido, Japan) since 2002 has shown that injection of CO2 into coal seams affected their permeability. Adsorption of CO2 caused swelling of the coal matrix and lowered the permeabil

Measurement of Threshold Capillary Pressure Using Data of CO2 Injection under Triaxial Compression Test on Mudstone

Autor: Yasuki OIKAWA, Takashi TAKEHARA, Xinglin LEI, Hiroki FUKAZAWA, Tsutomu YAMAGUCHI

Publikováno v: Journal of MMIJ, Vol 136, Iss 10, Pp 110-116 (2020)

Elucidating the sealing capacity of caprock is very important because CO2 sequestered in deep aquifers can remain there for several hundred years in the CO2 sequestration. Threshold capillary pressure is a key property affecting sealing capacity, and

A Practical Approach to Diagnosis of Spinal Dysraphism

Autor: Nitamar Abdala, Laila Cristina Alves Rojas, Gustavo Dalul Gomez, Bárbara Trapp, Danilo Manuel Cerqueira Costa, Tomás de Andrade Lourenção Freddi, Monique de Oliveira Morais Hans, Isadora Fonseca Teixeira Lemos Calixto, Henrique Carrete Junior, Stênio Burlin, Emi Fujino, Eduardo Takashi Takehara, Luis Antônio Tobaru Tibana

Publikováno v: RadioGraphics. 41:559-575

Spinal dysraphisms (SDs) are congenital malformations of the spinal cord, determined by derangement in the complex cascade of embryologic events involved in spinal development. They represent a heterogeneous group ranging from mild clinical manifesta
