Allergic Rhinitis in Professional Singers: A Monoinstitutional Series.

Objective: In professional singers, allergic rhinitis can lead to dysphonia and alterations in resonance. Each episode of laryngeal inflammation increases the risk of vocal strain or forces singers to cancel performances. This study aimed to analyze differences between allergic and nonallergic professional singers in self-evaluation of voice quality, objective examination of voice, and limitations of professional activities due to voice troubles.

Design and Production of Functionalized Electrospun Fibers for Palladium Recovery.

Adsorption stands out as a leading wastewater treatment method for ion removal or recovery. Polymeric fibers, notably electrospun ones, are gaining prominence due to their high capacity and easy recovery. Electrospinning offers a cost-effective means to produce fibers with a large surface area and high adsorption capacity.

Waste-derived catalysts for tar cracking in hot syngas cleaning.

Catalytic tar cracking is a promising technique for hot syngas cleaning unit in gasification plants because it can preserve tars chemical energy, so increasing the syngas heating value. The cost associated with catalyst preparation is a key issue, together with its deactivation induced by coke deposition. Iron is a cheap and frequently used catalyst, which can also be found in some industrial wastes.

Cyan Hydrogen Process: A New Route for Simultaneous Hydrogen Production and Carbon Valorization.

Hydrogen is expected to largely contribute to the near-future circular economy. Today, most hydrogen is still produced from fossil fuels or renewable pathways with low efficiency and high cost. Herein, a proof of concept for a novel hydrogen production process is proposed, here named cyan hydrogen inspired by a combination of the green and blue processes, due to the key role played by water and the low carbon content in the gas phase, respectively.

Partial Horizontal Supracricoid Laryngectomy: Which Factors Impact on Post-decannulation Swallowing Outcomes? A Prospective Single-Center Experience.

Early decannulation, performed within the first ten days after supracricoid partial laryngectomy, can result in a more rapid recovery of swallowing function with a semisolid bolus in the short term, about 30 days. We selected 20 patients with squamous cell carcinoma of larynx, who underwent supracricoid laryngectomies: 10 cricohyoidopexy (CHP) and 10 cricohyoidoepiglottopexy (CHEP). Staging was pT2 (10 pts), and pT3 (10 pts).
