Australian and New Zealand Journal of Ophthalmology, 1986 AbstractInvolutional ptosis was corrected by either an anterior or posterior approach in 105 eyelids The posterior approach was preferred unless there was a specific indication for the anterior approach which included excess skin and bulky eyelids At operation approximately 10% of cases were found to have fatty degenerative changes in the anterior part

Evolutes and Involutes of Frontals in the Euclidean Plane
Demonstratio Mathematica, 2015 We have already defined the evolutes and the involutes of fronts without inflection points. For regular curves or fronts, we can not define the evolutes at inflection points. On the other hand, the involutes can be defined at inflection points.

Reduction of contact stresses using involute gears with asymmetric teeth [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2015 Asymmetrical involute gears have a different value of the operating pressure angle for right and left side of the gear. These teeth are suitable for one direction of rotation. Such teeth enable to change the length of the generating line.

Power analysis of chain transmission with gear chain and involute sprockets
Advanced Engineering Research, 2021 Introduction. The power analysis of a chain transmission with a toothed chain and involute sprockets considers the centrifugal forces and the friction coefficients between the plate and the sprocket tooth. The work objectives are to determine all meshing

A Duality for Involutive Bisemilattices [PDF]
Studia Logica, 2018 We establish a natural duality between the category of involutive bisemilattices and the category of semilattice inverse systems of Stone spaces, using Stone duality from one side and the representation of involutive bisemilattices as Płonka sum of Boolean algebras, from the other. Furthermore, we show that the dual space of an involutive bisemilattice
