The final date of the Antikythera mechanism
(Science History Publications Ltd, 2017-08)
The Antikythera mechanism is a mechanical astronomical instrument that was discovered in an ancient shipwreck (from about 60 bce) at the beginning of the twentieth century. A consensus does not exist on the question of ...
Effect of thermal and mechanical cycles on the hardness and roughness of artificial teeth
(2015)
In this study the effects of thermal and mechanical cycles on the hardness and roughness of artificial teeth were evaluated. Materials and Methods:Specimens were prepared and stored in distilled water at 37ºC for 48 hours ...

Respiratory mechanics in infants with severe bronchiolitis on controlled mechanical ventilation
(BioMed Central, 2017-10)
Background: Analysis of respiratory mechanics during mechanical ventilation (MV) is able to estimate resistive, elastic and inertial components of the working pressure of the respiratory system. Our aim was to discriminate ...
