Background: Although isolated congenital absence of lower lateral cartilages are rare deformities, they deserve special attention of plastic surgeons performing rhinoplasty as these Leather anomalies may pass unnoticed by the patient and the plastic surgeon; until confronting them during surgery.Methods: From August 2017 to December 2017, four case
Thermal error is one of the main reasons for the loss of accuracy in lathe machining.In this study, a thermal deformation compensation model is presented that can reduce the influence of spindle thermal error on machining accuracy.The method used involves the collection of temperature data from the front and rear spindle bearings by means of embedd
Abstract Background A number of negative developmental outcomes in response to extreme temperature have been documented.Yet, to our knowledge, environmental research has left the question of the effect of temperature on human neurodevelopment largely unexplored.Here, we aimed to investigate the effect of ambient temperature on linguistic developmen
