A fundamental study of scale formation of calcium carbonate (CaCO3) for producing oil wells has been carried out. This article presents the study of the prediction of salt deposition in two different synthetic formation waters and investigates the effects of temperature and pressure on calcium carbonate precipitation. The dependence of the induction period of the precipitation of calcium carbon...

Railways were originally uniquely identified with the material of their initial construction and now are technically identified by the characteristic contact of ‘steel wheel on steel rail’. Over 160 years ago failures of iron railway axles led to research into what we now know as metal fatigue. Accidents throughout the ages have acted as catalysts for research and improvements: this lecture wil...

The Speech Cycling Task (SCT) is a novel experimental paradigm developed together with Robert Port and Keiichi Tajima at Indiana University. In a SCT, subjects repeat a phrase containing multiple prominent, or stressed, syllables in time with an external timer, which can be simple or complex. A phase-based collective variable is deened in the acoustic signal. This paper reports on two experimen...

The synergetic effects of dietary obesity and stress induced by electrical shocks on insulin secretion from the perfused pancreas, the action of insulin on adipose tissues and glucose tolerance were studied in rats. The rat was fed either a control (C) (50% starch) or a high fat diet (F) (40% butter) for a period of 12 weeks. Half of the rats on each diet received electrical shocks, one hour pe...

The use of motor primitives for the generation of complex movements is a relatively new and interesting idea for dimensionality reduction in robot control. We propose a framework in which adaptive primitives learn and represent synergetic arm movements. A simple and fixed set of postural and oscillatory primitives form the substrate through which all control is elicited. Higher level adaptive p...

We represent a theory of polymer gelation as an analogue of liquid-glass transition in which elastic fields of stress and strain shear components appear spontaneously as a consequence of the cross-linking of macromolecules. This circumstance is explained on the basis of obvious combinatoric arguments as well as a synergetic Lorenz system, where the strain acts as an order parameter, a conjugate...

Erythropoietin (EPO) has a beneficial effect on hepatic cell proliferation during liver regeneration. However, the underlying mechanism has not yet been elucidated. To uncover the proliferation response of EPO in rat liver regeneration after partial hepatectomy (PH) at the cellular level, hepatocytes (HCs) were isolated using Percoll density gradient centrifugation. The genes of the EPO-mediate...
