Textured polyester multifilament yam was subjected to swelling in single and mixed solvents (with varying ratio) at room temperature for different durations. The changes in the structure and properties of the yam were investigated by measuring birefringence, crystallinity, critical dissolution time, shrinkage on treatment, % change in bulk, residual shrinkage, crimp rigidity, dye uptake and dye...

Kinsky, Stephen C. (Washington University, St. Louis, Mo.). Effect of polyene antibiotics on protoplasts of Neurospora crassa. J. Bacteriol. 83:351-358. 1962.-The polyene antibiotics nystatin, amphotericin B, and filipin induced shrinkage of Neurospora crassa protoplasts stabilized in sucrose. At low concentrations of filipin (5 mug per ml), or higher concentrations of nystatin and amphotericin...

The hydro-swelling of smectite clay minerals in low-permeability reservoirs further decreases the reservoir permeability and results low oil recovery. Currently, traditional chemical anti-swelling agents are widely used, but most them only effective short term not environmentally friendly. Here, we report use Fe(III) reducing microorganisms (FeRM) as a novel green agent to enhance recovery from...

The Kelly betting criterion ignores uncertainty in the probability of winning the bet, and uses an estimated probability. In general, such replacement of population parameters by sample estimates gives poorer out-of-sample than in-sample performance. We show that to improve out-of-sample performance the size of the bet should be shrunk in the presence of this parameter uncertainty, and compare ...

To identify protein kinases (PK) and phosphatases (PP) involved in regulation of the Na+-K+-2Cl-cotransporter in Ehrlich cells, the effect of various PK and PP inhibitors was examined. The PP-1, PP-2A, and PP-3 inhibitor calyculin A (Cal-A) was a potent activator of Na+-K+-2Cl-cotransport (EC50 = 35 nM). Activation by Cal-A was rapid (<1 min) but transient. Inactivation is probably due to a 10%...
