“…We thus recommend local ventilation methods to be implemented into limited spaces to directly remove the infectious SARS-CoV-2-laden aerosols from the interpersonal breathing microenvironment. Local ventilation systems, for example, push and pull ventilation system and personalized ventilation system, are the ventilation methods that are used for transporting contaminants or heat from the occupied zone ( Olander et al, 2001 ; Huang et al, 2016 ; Luo et al, 2018 ). These systems are based on local capture of contaminants ( Biegert and Railio, 2001 ).…”

The term Glove Box probably creates an image of a glass box with black gloves, but Glove Boxes are as varied as the applications in which they are used. It is a hermetically sealed, watertight box, built for the purpose of sensitive applications. In this paper we present the design, the implementation and the testing of a Glove Box using plexiglass of 6mm thickness. The entire control of the system is flashed on an ATmega328 microcontroller. The sensors inside the box include oxygen sensor, gas sensor, humidity and temperature sensor. The plexiglass used provides robustness for the system but being lightweight it can be easily moved in different places in a research laboratory, compared with the steel Glove Boxes which are difficult to handle. The Glove Box was tested, by filling it up with Argon (inert gas) and introducing bulk heterojunction organic solar cells (BHJ OSC) and leaving them inside for 12hours. The measurement of the OSCs after 12h revealed that their efficiency decreased with only 20% compared to those left outside of the Glove Box which had an efficiency decrease of more than 70% from their initial value.

Background: Nail thickening is a poor prognostic factor in onychomycosis. Mechanical reduction by micromotor nail grinding is an alternative treatment for onychomycosis. However, this treatment introduces a large amount of infected nail dust particles into the air and can adversely affect other patients and health-care providers. The innovative recirculating airflow safety cabinet (ASC) was developed to prevent the spread of these generated infected nail dust particles. The aim of this study was to determine the efficacy of the ASC in patients with onychomycosis or traumatic onychodystrophy. Methods: The ASC was used during the nail-grinding process in 50 patients, including 36 onychomycosis patients and 14 traumatic onychodystrophy patients. For each patient, five Sabouraud dextrose agar plates with chloramphenicol were positioned within the working space of the ASC, and the other five plates were positioned near the area of air exit after the carbon filters within the cabinet. A total of 500 plates were incubated at 25°C and evaluated every 7 days. The results of fungal cultures were analyzed. Results: In the traumatic onychodystrophy group, all fungal cultures of nail dust particles from both before and after filtration from the ASC were negative in all 14 patients. In the onychomycosis group, 52 fungal cultures (28.9%) from nail particles within the ASC working area tested positive; however, the results of fungal cultures of nail dust particles after filtration were all negative. Conclusions: The newly developed ASC was found to be effective for preventing the spread of infected nail dust particles generated by micromotor nail grinding to mechanically reduce nail thickness in patients with onychomycosis.
