Objective: To evaluate the value of laminar flow in the treatment of burns.

Methods: The air in the laminar flow chamber and the wound tissues of the patients were sampled for bacterial detection. The number and stains of bacterial colony from different classes of laminar air flow chambers at different time points were inspected and compared.

Results: The bacterial number was 0 in the laminar flow chamber of 1000 grade, which was obviously different from that in the public area. The mortality was obviously decreased in the laminar air flow chamber with shorter treatment time and hospitalization. No wound infection occurred and the wounds healed smoothly in all these patients.

Conclusion: The application of laminar air flow can be helpful for the treatment of severe burns.

Purpose: To evaluate and compare the mycobacterial load using a mobile laminar airflow (LAF) device in an IVI-dedicated outpatient clean room (OCR) without ventilation systems and in a hospital-based operating theatre (HOT).

Methods: This case-control study was conducted in 2 different settings: OCR and HOT during a series of intravitreal injections (IVIs). The Air Microbial analysis was performed using a Surface Air System instrument at three different moments during the IVI sessions in both settings: at the operative site (OS), four meters from the OS (DOS) and in the disinfection room (DR).

Article Synopsis
  • High-altitude regions in China have a potential for renewable energy and ammonia production, leading to a proposed co-combustion strategy of methane and ammonia to lower carbon emissions.
  • A specialized combustion system was used to test how different ammonia mixing ratios, equivalence ratios, and pressures affect nitrogen oxide (NO) emissions in flames fueled by methane and ammonia.
  • Findings show that higher ammonia ratios increase NO emissions in stoichiometric flames but remain constant in fuel-rich flames at ratios above 10%. Sub-atmospheric pressure raises NO levels, especially in fuel-rich conditions, but doesn't significantly change nitrogen conversion pathways.

We report the development of a multi-pass diode laser absorption spectroscopy system for simultaneous measurements of soot volume fraction (SVF), temperature, and CH concentration using a single diode laser near 1.543 µm. A line-shaped beam spot pattern is chosen for the open-path Herriott multi-pass cavity, enabling sensitive detection at various heights above the burner with an effective optical absorption path length of approximately 1.
