Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Considering the Impact of Using Free-Body Diagram in Mechanics Problem-Solving on Improving Engineering Students’ Performance in Physics at a Selected Public University in Rwanda

Journal of Learning Theory and Methodology
Background. Engineering students often struggle with physics problem-solving, especially mechanics problems, while teaching mechanics helps students predict motion and force impacts, enabling creative engineering design tasks.

Elements of the anthropological theory of didactics in the selection of contents in a course of fluid mechanics in engineering, a case study in Spanish universities

SN Applied Sciences, 2021
The Anthropological Theory of Didactics has been applied to the field of didactics of mathematics with remarkable success. Fluid Mechanics is a discipline with a strong mathematical background, where mathematics is used for modeling the continuous nature.

Modulus difference-induced embedding strategy to construct iontronic pressure sensor with high sensitivity and wide linear response range

iScience, 2023
Summary: Sensitivity and linearity are two crucial indices to assess the sensing capability of pressure sensors; unfortunately, the two mutually exclusive parameters usually result in limited applications. Although a series of microengineering strategies

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Automatic generation of smart earthquake-resistant building system: Hybrid system of base-isolation and building-connection

Heliyon, 2016
A base-isolated building may sometimes exhibit an undesirable large response to a long-duration, long-period earthquake ground motion and a connected building system without base-isolation may show a large response to a near-fault (rather high-frequency)

Advances in statistical mechanics of rock masses and its engineering applications

Journal of Rock Mechanics and Geotechnical Engineering, 2021
To efficiently link the continuum mechanics for rocks with the structural statistics of rock masses, a theoretical and methodological system called the statistical mechanics of rock masses (SMRM) was developed in the past three decades.

リョウシ リキガク B [PDF]

, 2007
最初に、行列力学とブラ・ケット記法による状態の概念を用いて、量子力学Aで導入された量子力学をより深く理解させる。次に、実用上重要な摂動法を詳説した後に、量子力学に特有なスピン角運動量を導入して電子と電磁場との相互作用を取り扱う。最後に、多粒子系の状態の表し方、角運動量の合成と角運動量間の相互作用、多粒子系の近似的取り扱い方を議論して、現実の系を取り扱う場合の基本を習得させる。大阪大学OpenCourseWare ...
