Activated sludge plants (ASP) are associated with the stable foaming problem worldwide. Apart from the physical and chemical treatment methods, biological treatment method has been least explored and may prove to be a novel and ecofriendly approach to tackle the problem of stable foam formation. In ASP Nocardia species are commonly found and are one of the major causes for forming sticky and st...

Most of the existing fabrication techniques for tissue engineering scaffolds require the use of organic solvents that may never be fully removed even after long leaching hours. The residues of these organic solvents reduce the ability of biological cells to form new tissue. This paper presents an approach toward solvent-free fabrication of tissue engineering scaffolds. Interconnected porous str...

The results of determining the compressive strength non-autoclaved foam concrete based on a protein foaming agent under different temperature-humidity conditions are presented

foaming conditions of the red beet (beta vulgaris l) puree were optimized using response surface methodology (rsm) with respect to arabic gum concentrations (0.01 – 0.4% w/w), red beet puree (40 _ 60% w/w),egg white concentration( 5 _ 15% w/w) and whipping time (3 – 9 min) for minimum foam density and foam drainage volume as response variables. foams were prepared from various pulp concentratio...

This work is a systematic study of the strength and ultrasonic properties cemented paste backfill incorporating foaming agent, known as foam-cemented (FCPB). Based on determining optimal admixture contents (foaming stabilizer, thickening agent), series uniaxial compressive (UCS) tests were conducted to determine relationship between UCS FCPB four influencing factors, i.e., cement–tailings ratio...
