Interventions used to reduce infectious aerosol concentrations in hospitals-a review.
EClinicalMedicine
January 2025
WEISS Centre, University College London, UK.
Background: The COVID-19 pandemic highlighted the need for improved infectious aerosol concentrations through interventions that reduce the transmission of airborne infections. The aims of this review were to map the existing literature on interventions used to improve infectious aerosol concentrations in hospitals and understand challenges in their implementation.
Methods: We reviewed peer-reviewed articles identified on three databases, MEDLINE, Web of Science, and the Cochrane Library from inception to July 2024.
Influence law of air flow and water immersion duration on the risk of secondary oxidation spontaneous combustion of coal.
Sci Rep
January 2025
School of Civil and Transportation Engineering, Ningbo University of Technology, NiBo, 315211, China.
Article Synopsis
- The study investigates the risk of spontaneous combustion in lignite coal under varying air flows and immersion times.
- It finds that long-term water-immersed coal shows lower oxygen consumption and heat release at higher temperatures during the primary oxidation process compared to short-term water-immersed coal.
- In the secondary oxidation phase, long-term water-immersed coal has higher oxygen consumption and heat release rates, while increased air flow and longer immersion times elevate the risk of spontaneous combustion.
Fluidic Oscillation-Based Pneumatic Actuation for Soft Locomotion and Grasping.
Soft Robot
December 2024
Key Laboratory of Mechanism Theory and Equipment Design of Ministry of Education, School of Mechanical Engineering, Tianjin University, Tianjin, China.
Most pneumatic actuators used in robotics are controlled by valves that contain moving parts (e.g., spool or rotor) and electronics to change the direction or pressure of the air flow.

November 2024
School of Safety Science and Engineering, Liaoning University of Engineering and Technology, Fuxin, Liaoning 123000, China.
Article Synopsis
- * Researchers monitored gas concentrations and proposed a combination method of oxygen spraying and using air guide cloth to improve oxygen levels in the working face return airway.
- * Using simulation and a PLC control program, they found that with appropriate pressures, oxygen levels improved significantly, confirming that the outlined techniques could effectively manage low oxygen conditions.
Understanding the clinical management of co-occurring sleep-related bruxism and obstructive sleep apnea in adults: A narrative and critical review.

Sleep-related bruxism (SRB) is a motor oral behavior characterized by tooth grinding and jaw clenching activity, reported by 8%-12% of the adult general population and 3% of older individuals. The frequency of one of its biomarkers, rhythmic masticatory muscle activity (RMMA), remains elevated across ages. Obstructive sleep apnea (OSA) is associated with the brief and repetitive pause of breathing (apnea) and with transient reduction in oxygen (hypoxia).
