Superposed remanent magnetization and magnetic fabric in Triassic carbonates of Tethys Himalaya (Jomsom area, Nepal): chronological and tectonic implications

Pitambar Gautam, Kohki Yoshida, Megh Raj Dhital, Shigeyuki Suzuki et autres

Carbonates from three sections in Tamba Kurkur and Mukut Formations near Jomsom in Nepal were investigated for natural remanent magnetization (NRM) and anisotropy of magnetic susceptibility (AMS). NRM comprises up to three components: a recent field component (RF) residing on magnetite/maghemite (soft …

Magnetic Susceptibility Measurement To Recognize Geological Characteristics of Rocks : An Example From the Crustal Section in the Northeast of the Yakuno Ophiolite, Japan

Shinya Wada, Takafumi Kimura, Takahiro Oyama, Shigeyuki Suzuki et autres

岩石の帯磁率は含有される強磁性鉱物の種類，量，粒径などと相関することで知られ，簡便な装置により非破壊で測定できるため，岩石の地質学的特徴を迅速に把握する際に活用できると期待される．一方で，帯磁率は多様な指標に対して感度を有するが故に，測定対象が複数の特徴を有する場合，その特徴が重なり合ってしまうことがある．これを克服できれば，幅広い現場での情報収集作業に貢献があるが，そのような検討事例は乏しい．本研究では，大島半島北部で実施された大深度ボーリングのコア試料を使用して，夜久野オフィオライトの地殻セクションの帯磁率を連続的に測定し，帯磁率から複合的な地質学的特徴がどのように把握できるか検討した．岩石の組織観察，鉱物モード組成分析，X線CT撮影，ポータブルXRF測定から検証した結果，地質境界や変質の影響がセンチメートルスケールの帯磁率の変化に反映され，玄武岩類の化学組成がメートルスケール以上の帯磁率の変化に反映されることが明らかとなった．本研究で議論された帯磁率の絶対値や変化のスケールに着目して複合的な地質学的特徴を把握する手法は，多様な現場の野外調査やコア記載において，応用されることが期待される．

Acute and Prolonged Effects of 300 sec of Static, Dynamic, and Combined Stretching on Flexibility and Muscle Force

Shingo Matsuo, Masahiro Iwata, Manabu Miyazaki, Taizan Fukaya et autres

Static stretching (SS), dynamic stretching (DS), and combined stretching (CS; i.e., DS+SS) are commonly performed as warm-up exercises. However, the stretching method with the greatest effect on flexibility and performance remains unclear. This randomized crossover trial examined acute and prolonged effects of …

Effects of High-Intensity Stretch with Moderate Pain and Maximal Intensity Stretch without Pain on Flexibility

Genki Hatano, Shingo Matsuo, Yuji Asai, Shigeyuki Suzuki et autres

In this study, we aimed to identify the time course effects of different intensities of static stretch (SST) (maximal intensity without pain vs. high-intensity with moderate pain) on flexibility. This study included 16 healthy students (8 men and 8 women) who performed …

Application of the novel estimation method by shear wave elastography using vibrator to human skeletal muscle

Wakako Tsuchida, Yoshiki Yamakoshi, Shingo Matsuo, Mayu Asakawa et autres

In recent years, non-invasive measurement of tissue stiffness (hardness) using ultrasound elastography has attracted considerable attention. It has been used to evaluate muscle stiffness in the fields of rehabilitation, sports, and orthopedics. However, ultrasonic diagnostic devices with elastography systems are expensive and …
