the term 'membrane bioreactor' expresses a combination of activated sludge and membrane separation processes. the need to processes like sedimentation and disinfection used in common methods is eliminated through mbr systems in a way that membranes are placed into or out of an aeration tank and the vacuumed wastewater created by the suction pump is pulled up from inside the membranes and leaves...

In this work, the photokilling of Escherichia coli using a “one-pot” synthesized suspension of anatase crystallized nanoparticles is evaluated. Preliminary to the biological tests concerning the antibacterial efficiency, the fabricated suspension, using a derived sol-gel process in soft chemistry condition, is characterized. Structural properties of the nanoparticles are investigated using Elec...

The thermal resistance of Listeria monocytogenes associated with a milk-borne outbreak of listeriosis was determined in parallel experiments by using freely suspended bacteria and bacteria internalized by phagocytes. The latter inoculum was generated by an in vitro phagocytosis reaction with immune-antigen-elicited murine peritoneal phagocytes. The heat suspension medium was raw whole bovine mi...

Building, bridge or wind turbine maintenance requires manual dexterity tasks by a specialist rope-access trained workforce via two principal means: harness suspension of individual workers from above, deployment suspended platform cradle which access the structure to be maintained. Currently no published research compares accuracy and efficiency simulated between these modalities. This study in...

We consider a system of a very large number of particles of very diierent sizes, suspended in a carrier uid. These particles move due to diiusion and superimposed transport processes, merge to form larger clusters, or fragment into smaller ones. In the present paper a mathematical model for such processes is derived, consisting of an innnite quasilinear reaction-diiusion system, coupled to the ...

The inability to capture the physics of solid-particle suspension in turbulent fluid flow is holding back application of multiphase computational fluid dynamics techniques to the many problems involving particle suspension in nature and society. We present a theory for particle suspension capacity near no-slip frictional boundaries of turbulent flows. The suspension capacity parameter Γ include...

Suspension-based tabling systems have to save and restore computation states belonging to OR branches. Stack freezing combined with (forward) trailing is among the better-known implementation approaches for this purpose. Resuming a goal using this technique reinstalls the bindings for all the variables in the environment where the goal was suspended. In this paper we explore an alternative appr...

In this paper we present modeling and control of a multicable suspended mechanism called the ‘2D SpiderCrane’. A spidercrane does not have any conventional heavy components and makes use of cables by virtue of which high transfer speeds are achievable. The initial part of the paper addresses the modeling of the mechanism, where the cable and pulley dynamics are separated, and the payload is vie...
