Kidney Stone Dissolution By Tetherless, Enzyme‐Loaded, Soft Magnetic Miniature Robots
Advanced Healthcare Materials, EarlyView.Wireless magnetic robots are developed for kidney stone dissolution. The robots navigate through a urinary tract model from bladder and ureter to renal pelvis with the help of external magnetic fields. The filaments are loaded with urease enzyme which catalyzes urea to carbon dioxide and ammonia, thereby increasing pH to basic regime and supporting ...

Perceived duration increases with contrast, but only a little.
Frontiers in Psychology, 2016 Recent adaptation studies provide evidence for early visual areas playing a role in duration perception. One explanation for the pronounced duration compression commonly found with adaptation is that it reflects adaptation-driven stimulus-specific ...

The Effect of Color Filters on the Visual Acuity and Contrast Sensitivity in Low Vision Patients
Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2010 BACKGROUND AND OBJECTIVE: Low vision is defined as, distance visual acuity in the better eye is 20/200 or less or visual field in better eye is less than 20 degree. In this patient contrast sensitivity decreased. The use of colored filter for improve the
