The Corporate (Magic) Circle: Fun Work or Controlled Play?

Entertainment games have traditionally been articulated as leisure. However, they have also been used in the work context, in the form of serious games or gamification. In this qualitative research, we aimed to investigate the purpose of games used in the work context.

Telework and Mental Health during COVID-19.

COVID-19 has come to change societal organization. Due to lockdowns, work typologies have been rethought and telework has gained strength. However, the impact of the constant use of information and communication technologies on the mental health of workers needs to be considered.

Removal of pathogens by ultrafiltration from sea water.

Among water treatment processes, ultrafiltration is known to be efficient for the elimination of micro-organisms (bacteria and viruses). In this study, two pathogens were targeted, a bacterium, Vibrio aestuarianus and a virus, OsHV-1, with the objective to produce high quality water from seawater, in the case of shellfish productions. The retention of those microorganisms by ultrafiltration was evaluated at labscale.

Optimization of Air Backwash Frequency during the Ultrafiltration of Seawater.

The main objective of this paper is to study the effect of new air backwash on dead-end ultrafiltration of seawater with a pilot at semi-industrial scale (20 m/day). To control membrane fouling, two different backwashes were used to clean the membrane: classical backwash (CB) and new air backwash (AB) that consists of injecting air into the membrane module before a classical backwash. To evaluate the efficiency of AB and CB, a resistance in series model was used to calculate each resistance: membrane (R), reversible (R) and irreversible (R).

Air Backwash Efficiency on Organic Fouling of UF Membranes Applied to Shellfish Hatchery Effluents.

Among all the techniques studied to overcome fouling generated in dead-end filtration, the injection of air during backwashes proved to be the most effective. Indeed, shear stress engendered by the two-phase flow enhanced particle removal on membrane surface. This work aims to study the injection of air to drain the membranes before backwash.
