Convective drying of wastewater sludges: Influence of air temperature, superficial velocity, and humidity on the kinetics

in Drying Technology (2005), 23(8), 1667-1679

The influence of air temperature, velocity, and humidity during convective drying of two different sludges (A and B) is investigated through a 3 3 factorial design. For sludge A, a constant drying flux ... [more ▼]

The influence of air temperature, velocity, and humidity during convective drying of two different sludges (A and B) is investigated through a 3 3 factorial design. For sludge A, a constant drying flux period is observed, while sludge B is characterized by a long decreasing drying flux phase. A sensitivity analysis shows that temperature is the main operating parameter affecting the drying kinetics. Mass and heat transfer coefficients as well as water evaporation capacities are calculated from drying curves. Transfer coefficients are related to operating conditions through dimensionless relations. For both sludges, a linear relation is found between water evaporation capacity and the maximal measured drying flux. [less ▲]

In order to determine the fluid exchanges at the galleries wall during the excavation, drying tests of soils samples are achieved in a convective micro drying rig. The results of the drying tests permit to evaluate a mass transfer coefficient between the porous medium and the atmosphere. The influence of the drying temperature is studied. [less ▲]

Convenient Genotyping of Six Myostatin Mutations Causing Double-Muscling in Cattle Using a Multiplex Oligonucleotide Ligation Assay

We herein describe a procedure that allows for simultaneous genotyping of six loss-of-function mutations in the bovine myostatin gene associated with the double-muscling phenotype. The proposed method relies on a multiplex oligonucleotide ligation assay and detection of the fluorescently labelled products using automatic sequencers. [less ▲]

A new dispersion technique has been implemented which consists in the polymerization of a monomer in the presence of CNTs in a bad solvent of the polymer. During its formation, the polymer precipitates and entraps all the CNTs. Thanks to the establishment of a suitable CNTs dispersion, this method promotes much higher electrical conductivity in the resulting nanocomposite than more conventional techniques, i.e. melt-mixing and co-precipitation. Moreover, the quantity of solvent required is much lower than in the co-precipitation method that makes this process industrially viable. One potential application of these nanocomposites has been demonstrated by the preparation of foams using the supercritical CO2 technology that present very high electromagnetic interference (EMI) absorbing properties since more than 90% of the incoming power being absorbed in the foam.
