A Valve review of the literature related to the specialty of Otolaryngology was conducted to update current concepts used in malignant external otitis in order to improve the quality of the scientific and care services provided by our center and to improve educational aspects in undergraduate and postgraduate teaching.The current trend in the liter
Infectious Diseases of the Upper Gastrointestinal Tract
Infectious diseases of the upper gastrointestinal tract are rare, but certain bacteria including Treponema pallidum and Mycobacterium tuberculosis may infect the esophagus, stomach, and duodenum even in an immunocompetent individual.Gastric syphilis is difficult to diagnose because it presents with non-specific symptoms and diverse endoscopic findi
Evaluation of impulse noise reduction in hearing aids with technical measurements and ratings of discomfort
Short, impulse-like sounds such as slamming of a door or rattle of dishes can be uncomfortable for hearing aid users.Therefore, many hearing aids provide impulse (or transient) noise reduction (INR) that should reduce loud and short sounds without impairing desired signals.In this work, we want to address Grooming Foam the question whether hearing
Detection of Heavy Metals in Water Using Graphene Oxide Quantum Dots: An Experimental and Theoretical Study
In this work, we investigate by ab initio calculations and optical experiments the sensitivity of graphene quantum dots in their use as devices to measure the presence, and concentration, of heavy metals in water.We demonstrate that the quenching or enhancement in the optical response (absorption, emission) depends on the metallic ion considered.In
