Remedial dredging of contaminated bed sediments in rivers and lakes results in the suspension of sediment solids in the water column, which can potentially be a source for evaporation of hydrophobic organic compounds (HOCs) associated with the sediment solids. Laboratory experiments were conducted in an oscillating grid chamber to simulate the suspension of contaminated sediments and flux to ai...

When Mycobacterium tuberculosis was grown in Tween-albumin broth without any agitation, the bacilli replicated in the upper, oxygen-rich portion of the medium at a rate that was just balanced by the rate at which the bacilli settled toward the bottom of the tube. When the organisms that accumulated in the sediment were suspended and diluted into fresh medium, they exhibited synchronous replicat...

Research in convective heat transfer using suspensions of nanometer-sized solid particles in base liquids started only over the past decade. Recent investigations on nanofluid, as such suspensions are often called, indicate that the suspended nanoparticles remarkably change the transport properties and heat transfer characteristics of the suspension. Bending walls can also improve heat transfer...

Background The large-scale production of biopharmaceuticals commonly relies on the use of suspension cell cultures, since they provide higher yields than adherent cultures. However, most mammalian cells grow in adherent mode and therefore need to go through a process of adaptation to suspended growth, which is not always simple or feasible. In this context, microcarrier cultures have introduced...

In this paper we derive high-order asymptotic expansions of the effective viscosity properties of a dilute periodic suspension composed of freely-suspended arbitrarily shaped particles dispersed in an incompressible Newtonian fluid. High-order terms are not only function of the viscous moment tensor but also of a distortion tensor that characterizes the periodic array. Mathematics subject class...

Prostate cancer cells adhere to a tumor basement membrane, while secretory epithelial cells reside in a suprabasal cell compartment. Since tumor cells are derived from suprabasal epithelial cells, they experience de-novo substratum adhesion in the context of oncogenesis. We therefore analyzed whether cell-matrix adhesion could affect the protein expression and activity of the AR. In this study,...

The effect of serum on cell growth and monoclonal antibody (MAb) productivity was studied in a repeated fedbatch mode using both free-suspended and immobilized S3H5/gamma2bA2 hybridoma cells. In the suspension culture, serum influenced the cell growth rate but not the specific MAb productivity. The average specific growth rate of the suspension culture in medium containing 10% serum was approxi...
