Each of the unit lenses (12) has a cross section of a shape of an isosceles triangle having an apex angle (α) in the range of 80° to 87°, and is made of a radiation setting resin having a refractive index in the range of 1.57 to 1.59. The prism lens sheet has a half-...
Mem was explaining the mysteries of geometry to the little ones when her mother stepped out of the eastern horizon to hover above them. She hated when her mother appeared like this: eyes hollowed and dark, her feet in the branches of the sapodilla tree, her head brushing the sky. She wou...

Clips locate between setting cavities and engage stones (9), which are set in the normal way, at three points forming an isosceles triangle, leaving a maximum stone surface area on display.
Each of the unit lenses (12) has a cross section of a shape of an isosceles triangle having an apex angle (伪) in the range of 80 having a refractive index in the range of 1.57 to 1.59. The prism lens sheet has a half-brightness viewing angle of 65 difference between the half-...
The electrochemical method is applied to the mass transfer measurements in a fully developed turbulent flow in an Isosceles triangular duct with a narrow apex angle. The analysis of the measured fluctuating mass transfer coefficient on a point electrode results in the distribution of turbulent ...
The chassis defines an isosceles triangle with the wheels at the corners. The front wheel can be cambered inwardly. The rear wheel can be mounted on a steerable swinging arm with the steering pivot axis passing through the centre of gravity at an angle.GIRONDEAU CHRISTOPHE...
