Equilibrium data were determined for aqueous two-phase systems composed of poly(ethylene glycol) (PEG), maltodextrin (MD), and water. The systems were prepared by varying the PEG molar mass (4000 g•mol −1 , 6000 g•mol −1 , and 8000 g•mol −1 ) and the dextrose equivalent (DE) of the MD (10.5 and 15). The temperatures tested were 298.2 K, 308.2 K, and 318.2 K. For the systems studied it was observed that the molar mass of the PEG did not sensitively affect the equilibrium curve position, and as the DE of MD increased, the concentration of polymers used to form the phases decreased. In some systems temperature minimally influenced the displacement of the equilibrium curve.

The upholding of a Quality Management System (QMS) during situations requiring emergency changes is challenging for organizations. Change management may help ensure these changes are carried out in ways that, while achieving their objectives, promote the appropriate improvements in each context. In a QMS, according to ISO IEC 17025:2017, the change and improvement promoting sources are well-established and their actions occur in a planned manner. But what happens when the working conditions change abruptly, putting at risk the quality of the organization’s core activity? In order to answer this question the internal audit process was chosen as a example for the changes induced by the COVID-19 health emergency. The process of turning the annual internal audit from an in-person activity into the remote modality was evaluated. The ADKAR change management model was applied to assess motivational and perceptual aspects among participants of the 2020 and the 2021 remote audits. The conclusion was that Change Management adoption may assist processes improvement when risk assessment does not have enough data to conduct an accurate analysis.
