Process systems engineering (PSE) has been an active research field for almost 50 years. Its major achievements includemethodologies and tools to support processmodeling, simulation and optimization (MSO). Mature, commercially available technologies have been penetrating all fields of chemical engineering in academia as well as in industrial practice. MSO technologies have become a commodity, t...

A spectrophotometric method was developed for simultaneous quantification of pseudoephedrine hydrochloride (PSE) triprolidine hydrochloride (TRI) using second derivative method (zero-crossing technique). The second derivative amplitudes of PSE and TRI were measured at 271 and 321 nm, respectively. The calibration curves were linear in the range of 200 to 1,000 g/ml for PSE and 10 to 50 g/ml for...

The use of Pfizer selective enterococcus (PSE) agar with the membrane filter technique for the enumeration of fecal streptococci is limited due to the inability of the characteristic black precipitate, indicative of esculin hydrolysis, to diffuse from the medium through the membrane. A modification of the membrane filter technique that consisted of placing the membrane on PSE agar and overlayin...

The Linear System Analyzer (LSA) is a component-based problem-solving environment (PSE) for the manipulation and solution of large sparse linear systems of equations. Both the underlying component infrastructure and its application to the problem area of linear systems are introduced. Initial results indicate the utility of clearly separating the PSE infrastructure from the particular problem d...

Here we discuss the remarkable role of the statistical memory effects in the human brain functioning at photosensitive epilepsy (PSE). We have analyzed three independent statistical memory quantifiers for the magnetoencephalographic (MEG) signals. These quantifiers reflect the dynamical characteristics of neuromagnetic brain responses to a flickering stimulus of different color combinations. Re...

This paper presents an overview of the current process systems opportunities in power generation, storage and distribution. It puts in perspective how process systems engineering (PSE) has contributed to the area and explores the current technical problems that PSE can contribute to. Fuel cells, solar cells, wind turbines, flow batteries and rechargeable batteries as well as their interactions ...

Abstract Given recent sociocultural and economic changes that have created significant pressures on South Korean mothers, we were interested in understanding the factors might contribute to their sense of competence taking challenges childrearing. We examined several family conditions theoretically supportive mothers’ parenting self-efficacy (PSE), specifically whether PSE was associated with m...

Irradiation and storage increased lipid oxidation of normal and pale-soft-exudative (PSE) muscles, whereas dark-firm-dry (DFD) muscle was very stable and resistant to oxidative changes. Irradiation increased redness regardless of pork-quality type, and the increases were proportional to irradiation dose. Irradiation increased the production of sulfur-containing volatiles, but not lipid oxidatio...
