The effect of micro-architecture on the failure response of multi-layered lattice sandwich panels under three-point loading
Autor: Yuta Nagakura, Ayumi Omachi, Wesley J. Cantwell, Kuniharu Ushijima
Publikováno v: Journal of Sandwich Structures & Materials. 23:652-679
In this study, the failure behaviour of lattice sandwich panels under three-point loading has been studied using a nonlinear finite element analysis. This paper develops on a previous paper, where the similar failure behaviour was discussed. However,

Boysenberry, a hybrid Rubus berry, is mainly cultivated in New Zealand. We previously reported that consumption of boysenberry juice (BBJ) exhibited anti-obesity effects in high-fat feeding rats. In this study, we focused on the suppressive effect of

Thirteen new triterpenoids, dysotriflorins A–M (1–13), were isolated from Dysoxylum densiflorum barks, and their structures were elucidated on the basis of NMR spectroscopic data and X-ray crystallography. Dysotriflorins A, B, and K–M (1, 2, an

Autor: Yusuke Hirasawa, Hiroshi Morita, Alfarius Eko Nugroho, Yuta Nagakura, Toshio Kaneda, Osamu Shirota, Intan Safinar Ismail, Haruka Yoshida
Publikováno v: Bioorganic & Medicinal Chemistry Letters. 24:2437-2439
Four new chromone alkaloids, chrotacumines G-J (1-4), have been isolated from the barks of Dysoxylum acutangulum. Their structures and absolute configurations were elucidated on the basis of NMR and CD data. Chrotacumines G and J (1 and 4) showed ost
