About this deal

Walls, P. L. L. et al. Quantifying the potential for bursting bubbles to damage suspended cells. Sci. Rep. 7(1), 15102–15102 (2017). Nienow, A. W. The impact of fluid dynamic stress in stirred bioreactors—The scale of the biological entity: A personal view. Chem. Ing. Tech. 93(1–2), 17–30 (2021). Play with the possibility of making a stream of bubbles (this requires a long, slow, steady exhalation which activates the parasympathetic nervous system and is calming). Bubble Stress boasts a user-friendly interface, ensuring a seamless gameplay experience on your mobile device. Each bubble you successfully burst rewards you with a satisfying pop and a melodic chime, elevating the addictive nature of the game. Aim for the highest score, compete against friends and global players, and assert your dominance as the ultimate Bubble Stress champion.

This virtual bubble game is an excellent stress reliever. It’s simple. Start the app, press the bubbles with your fingers and make them burst. From now on, whenever you feel the pressure rising, all you have to do is take out your smartphone. Take out your stress on your virtual bubble game and relax at the sight of bursting bubbles.

Following eqn (3b) the pressure p required to obtain a constant oscillation amplitude ζ for all bubble radii R 0 is much higher far away from the resonance condition than at resonance. As a consequence, for an imposed oscillation amplitude ζ the pressure gradient ∇ p in eqn (7) and the Bjerknes forces will also be stronger away from resonance. We will use this strategy in Section 4.3 to apply strong Bjerknes forces while remaining in the linear range of the bubble oscillation amplitude ζ.

In parallel, the same process control strategy was tested in a batch that received a virus infection at 24 h. Due to the infection and VLP production, cell growth stopped (Fig. 5C), but oxygen consumption continued to increase (Fig. 5D). Additionally, at the timepoint of infection, the aeration rate increased to 0.06 SLPM. Compared to the reference process for the infected batch (Fig. 3), in this setup, there was no need to add pure oxygen, because increasing the stirring speed provided efficient oxygen transfer. The results of these batch cultivations are in line with Kioukia et al., where infected Sf9 cells were cultivated at 400 rpm with a similar stirrer without an influence in production 28.

To acquire the seed culture, cells were thawed from a working cell bank and cultured in Dynamis AGT Medium (A26175-01, Thermo Fisher Scientific, USA), supplemented with 8 mM l-Glutamine (25030081, Sigma-Aldrich, USA), 1:1000 Anti-Clumping Agent (01-0057AE, Thermo Fisher Scientific) and 0.7 mg/L G418 (108321-42-2, Thermo Fisher Scientific). For pre-cultures, cells were sub-cultured in Dynamis AGT Medium with 8 mM l-Glutamine every 3–4 days at 37 °C, in a humidified incubator (Heracell v10S 160, Thermo Fisher Scientific) with 5% v/v CO 2 and agitated at 200 rpm on an orbital shaker (88881102, Thermo Fisher Scientific). Cells were diluted to a total cell count (TCC) of 1.5 × 10 6 cells/mL in Dynamis AGT Medium before the shear stress tests. Bioreactor cultivation and setup

M. Versluis, D. E. Goertz, P. Palanchon, I. L. Heitman, S. M. van der Meer, B. Dollet, N. de Jong and D. Lohse, Phys. Rev. E, 2010, 82, 026321 CrossRef. Fig. 5 Shape oscillation modes observed in our experiments, shown for two oscillation periods (2/ f). From top to bottom, the applied frequency is f = 27.94 kHz, f = 29.2 kHz, f = 27.94 kHz, f = 19.45 kHz and f = 19.45 kHz. The first four rows show shape oscillations with clear modes k = 7, 6, 5 and 4 respectively. The last row shows an experiment for which shape oscillations are clearly detected but the corresponding mode k is difficult to ascertain. The red scale bars are 300 μm. The DASGIP bioreactor system (d i = 10 cm, h = 30 cm) was equipped with a six-blade Rushton impeller (d = 4.5 cm) sitting on the end of the stirrer shaft. It was further also equipped with a pH and a DO sensor (d = 1.2 cm, h = 32.5 cm), an L-sparger (d = 6 mm), a harvesting and a sample taking pipe (d = 4 mm) and a thermowell (d = 6 mm).

As you blow bubbles encourage kids to demonstrate their best karate moves to pop the bubbles. The only rule is no clapping the bubbles (that’s too easy), kids must use their feet and open hands to karate chop the bubbles. In addition to the breathing mentioned above, this simple exercise gets kids moving and using cross lateral movements (where arms and legs cross the body). This type of activity is a great stress reliever, and you may want to join in the fun if you’re feeling a little stressed yourself!
