Id Subject Object Predicate Lexical cue
T48 0-19 Sentence denotes Materials & methods
T49 20-64 Sentence denotes The experimental setup is shown in Figure 1.
T50 65-307 Sentence denotes The aerosol consisted of 10% NaCl in water from a nebulizer (Omron NE-C28P, mass median aerodynamic diameter of 3 μm) fed through one of the lung ports of a dummy head (Laerdal airway management trainer) lying face upward on an optical bench.
T51 308-504 Sentence denotes Prior to measurement, the airway was primed with aerosol by turning on the nebulizer briefly while squeezing the attached lung ten-times, then waiting for 30 s for the exhaled aerosol to disperse.
T52 505-658 Sentence denotes A fume extractor was running continuously above the head (ULT Jumbo Filter Trolley 2.0 running at 0.3 m/s in a position 15 cm above the tip of the nose).
T53 659-750 Sentence denotes After initiating the camera acquisition, the lung was squeezed by hand to deliver a breath.
T54 751-830 Sentence denotes These were measured to deliver 300 ml quite reproducibly (wright respirometer).
T55 831-952 Sentence denotes For the breath duration of 1 s, the average flow of 0.3 l/s is similar to the peak flow for a normal breath 0.5 m/s [26].
T56 953-1104 Sentence denotes The aerosol was visualized with a conical laser sheet generated with a 488 nm DPSS laser (Coherent Sapphire 75 mW) and axicon lens (Thorlabs AX1220-A).
T57 1105-1266 Sentence denotes The conical cyan sheet surrounds the face at a distance of approximately 2.5 cm from the nose and at a closer distance at the cheek to allow space for the masks.
T58 1267-1367 Sentence denotes A beam block was used at the axicon’s aperture to prevent direct illumination of parts of the dummy.
T59 1368-1377 Sentence denotes Figure 1.
T60 1379-1449 Sentence denotes Photographs of the setup, showing the laser cone on an unmasked dummy.
T61 1450-1596 Sentence denotes The extractor is turned off to enhance laser appearance (A) view from the left (B) view from top parallel to laser (C) view from the right bottom.
T62 1597-1695 Sentence denotes The camera was a 2048*2048 pixel sCMOS array (Andor Sona 4BV11) with Nikkor 50 mm F1.8 AI MF lens.
T63 1696-1768 Sentence denotes It recorded a sequence of 30 frames at 7 Hz (acquisition time of 10 ms).
T64 1769-1904 Sentence denotes Raw 16-bit images were processed in SAOimage DS9 by applying the ‘bb’ colormap on a value range of 100–20,000 counts using log scaling.
T65 1905-1952 Sentence denotes The masks and dummy used are shown in Figure 2.
T66 1953-2124 Sentence denotes The three-layer mask in Figure 2B has two outer layers each 0.4-mm thick made of 80% polyester 20% elastane with the internal filter layer being 1.0 mm 100% polypropylene.
T67 2125-2248 Sentence denotes The filter covers the area of the mouth and nose but around chin, cheeks and nose bridge the fabric is just a single layer.
T68 2249-2371 Sentence denotes Compliance with the testing methods of the CWA 17553 was claimed by the supplier but packaging was not marked accordingly.
T69 2372-2381 Sentence denotes Figure 2.
T70 2383-2417 Sentence denotes Photographs of the test materials.
T71 2418-2527 Sentence denotes (A) the unmasked dummy, (B) three-layer mask with middle filter layer removed, (C) single-layer textile mask.
T72 2528-2642 Sentence denotes Bottom row: (D) CE marked FFP1 personal protective equipment mask, (E) CE marked Type 2 medical mask, (F) bandana.
T73 2643-2766 Sentence denotes The single layer mask in Figure 2C is of unknown 1.0-mm thick material, of a design which was cheaply and widely available.
T74 2767-2809 Sentence denotes Compliance with CWA 17553 was not claimed.
T75 2810-2924 Sentence denotes The CE-marked FFP1 respirator mask in Figure 2D has no exhalation valve and it is marked as complying with EN 149.
T76 2925-3037 Sentence denotes The CE-marked type 2 medical mask in Figure 2E had a metal nose clip which was cinched down firmly on the dummy.
T77 3038-3090 Sentence denotes The packaging was marked as complying with EN 14683.
T78 3091-3220 Sentence denotes The bandana or neck gaiter in Figure 2(f) was 0.33 mm thick 100% polyester and was folded into three layers in these experiments.
T79 3221-3356 Sentence denotes Dating from 2019 this was never intended for infection control, although the same material has been seen to be used as a face covering.
