Constructions of squaring the circle, doubling the cube and angle trisection / Koнструкции квадратура круга, удвоение куба и трисекция угла / Konstrukcije kvadrature kruga, udvajanja kocke i trisekcije ugla

open access: yesVojnotehnički Glasnik, 2017
The constructions of three classical Greek problems (squaring the circle, doubling the cube and angle trisection) using only a ruler and a compass are considered unsolvable. The aim of this article is to explain the original methods of construction of

Effect of 10-minute oropharyngeal exercise on the apnoea–hypopnoea index

open access: yesScientific Reports
Previously reported oropharyngeal exercises are long and difficult to perform. Therefore, we created a 10-min daily oropharyngeal exercise program and conducted a study to confirm its effectiveness.
