An algorithm for Ph/Ph/c queues
European Journal of Operational Research, 1986A new algorithm is presented for the numerical analysis of multi-server queueing systems with interarrival and service time distributions of phase type, including both finite and infinite capacity models. The algorithm is based on the iterative solution of balance equations by using successive overrelaxation and aggregation.

IEE Proceedings D Control Theory and Applications, 1987
The paper summarises a recent investigation to find out what contribution could be made to pH regulation by modern algorithms for online estimation and/or adaptive control. Topics discussed include a mathematical model to account for nonlinearity; full-scale trials using selftuning controllers; a specially developed nonlinear estimator; use of ...

APPROXIMATION OF PH/PH/c RETRIAL QUEUE WITH PH-RETRIAL TIME
Asia-Pacific Journal of Operational Research, 2014We consider the PH/PH/c retrial queues with PH-retrial time. Approximation formulae for the distribution of the number of customers in service facility, sojourn time distribution and the mean number of customers in orbit are presented. We provide an approximation for GI/G/c retrial queue with general retrial time by approximating the general ...

[Mo{P(Ph)2OC6H3(Ph)(η6-Ph)}(CO)2] [PDF]
Acta Crystallographica Section C Crystal Structure Communications, 1994 Dicarbonyl[(2-η 6 -phenyl-6-phenylphenoxy)diphenylphosphine-P]molybdenum contains a new phosphine ligand bound to Mo through the O atom and via an η 6 -arene interaction. A «three-legged-piano-stool» geometry is present with Mo-P=2.354 (1) A, Mo-C(carbonyl)=1.942 (4) and 1.944 (5) A and Mo-C(aryl)=2.295 (4)-2.339 (4 ...

Constant pH simulations of pH responsive polymers
The Journal of Chemical Physics, 2016Polyacidic polymers can change structure over a narrow range of pH in a competition between the hydrophobic effect, which favors a compact state, and electrostatic repulsion, which favors an extended state. Constant pH molecular dynamics computer simulations of poly(methacrylic acid) reveal that there are two types of structural changes, one local and ...

ON THE VISCOSITY AND pH OF SYNOVIAL FLUID AND THE pH OF BLOOD
The Journal of Bone and Joint Surgery. British volume, 19591. The results of viscosity measurements on a number of normal, traumatic and osteoarthritic synovial fluids from human knee joints are described and discussed. 2. A decrease of the viscosity of normal synovial fluid with age has been found. 3. The decrease of the viscosity with age and in the pathological groups is analysed and its relation to the ...

THE concept of intracellular pH depends on the assumption that the cell is either not divided into compartments, or that the volumes of the compartments are large enough to contain a statistically meaningful number of hydrogen ions, the “intracellular pH” in this case being a mean of the pH values in the various compartments.

pH measurements in ultranarrow immobilized pH gradients
Journal of Biochemical and Biophysical Methods, 1986It is possible to measure pH values in immobilized pH gradients (IPG) when the polyacrylamide matrix is made to contain an additional, carrier ampholyte-generated pH gradient. After an IPG run, 5 mm gel segments, along the separation axis, are cut and eluted in 300 microliter of 10 mM KCl and the pH read with a standard pH meter. When using ultranarrow

The High pH and pH-Shift Refolding Technology
Current Pharmaceutical Biotechnology, 2010We have developed a high-pH, pH-shift refolding "Ph-Fold technology", both for academic research and industrial protein drug development applications. Using this technology, we were able to refold some "difficult-to-refold" proteins, some of which are proven important drug targets and protein drug candidates. The technology is composed of the initial E.
