Effects of pressure angle on tooth deflection and root stress.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1986
This paper presents a study on the effects of pressure angle on tooth deflection and root stress. The analyses of tooth deflection and bending moment at root fillet due to a concentrated load on a gear tooth with various pressure angles were carried out by the finite difference method (FDM) and the results were compared with those measured.

A genome-wide association study of intra-ocular pressure suggests a novel association in the gene FAM125B in the TwinsUK cohort

, 2014
Glaucoma is a major cause of blindness in the world. To date, common genetic variants associated with glaucoma only explain a small proportion of its heritability. We performed a genome-wide association study of intra-ocular pressure (IOP), an underlying

GWAS-by-subtraction reveals an IOP-independent component of primary open angle glaucoma

Nature Communications
The etiology of primary open angle glaucoma is constituted by both intraocular pressure-dependent and intraocular pressure-independent mechanisms.

Root stresses of helical gears with highr pressure angle.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1986
本論文では,まず種々の圧力角の高歯歯車に集中荷重が作用する場合の歯のたわみ,曲げモーメントを差分法により求め,計算結果が測定結果とよく一致することを確かめるとともに,これらを求めるための近似式を導いている.さらにこれらの式と久保・梅澤の方法を用いて高圧力角並歯,高歯はすば歯車のかみあい時の歯元応力を計算し,測定結果と比較するとともに,歯元応力に及ぼす圧力角,歯たけの影響について明らかにしている.

Mathematical Modelling of flow in Schlemm's canal and its influence on primary open angle glaucoma

, 2008
POAG (Primary Open Angle Glaucoma) is a major cause of blindness. This normally occurs when the IOP (intraocular pressure) increases. High pressure can be caused by an imbalance in the production and drainage of fluid (aqueous humour, AH) in the eye.
