Effect of dehydration and pulsed light treatment on decontamination of minced onions: Microbial safety and physicochemical properties.

Microbial contamination of dehydrated onion products is a challenge to the industry. The study focused on opting for a suitable drying condition for minced onion and exploring the decontamination efficacy of pulsed light (PL) treatment conditions for the dehydrated product. The minced onions were hot air dried at 55-75°C for 280 min.

Retronychia refers to the embedding of the nail into the proximal nail fold. Patients present with chronic paronychia in the setting of disrupted nail growth. Nail avulsion is curative and unlike other forms of ingrown nails, it does not tend to recur.

Flow characteristics of positive and negative pressure irrigation in an immature tooth - A computational fluid dynamics study.

Aim: This study aims to investigate the irrigation dynamics in an immature tooth during positive and negative pressure irrigation using a computational fluid dynamics (CFDs) model.

Materials And Methods: Cone-beam computed tomography scan of the maxillary central incisor with Cvek's stage III root development was used for the reconstruction of the root canal geometry. The computer-aided design models of open (front vent and notched) and closed (side vent [SV]) needles were positioned inside the root canal at two penetration depths, i.
