Polyphenol oxidases (PPO) are enzymes that catalyze the browning of fruits and vegetables when oxygen in air reacts with present phenolic compounds. This study demonstrates enzymatic food samples inhibition its activity by common household materials. Fresh were tested different treatments acidic ionic solutions, syrups. Observations from students’ work showed changes pH, surface area for site r...

In this chapter we will describe and analyze a simulation of a factual information seeking system for a subsection of the "yellow pages". The subsection contains information about (i) car hire (ii) restaurants, and (iii) personal insurance. The simulation was accomplished by use of the so-called Wizard of Oz technique. In this technique, subjects who believe they are communicating with a protot...

Results from a three-dimensional axisymmetric resistive magnetohydrodynamic ~MHD! simulation are compared to experimental data from the Swarthmore Spheromak Experiment ~SSX! @M. R. Brown, Phys. Plasmas 6, 1717 ~1999!#. The MHD simulation is run under conditions and with dimensionless parameters similar to the experiment ~Lundquist number S51000, plasma beta b 50.1). The simulation is shown to r...

A few studies have reported magnetic fi eld changes during bioenergy healing. In a pilot experiment, we examined magnetic fi eld activity during hands-on healing and distant healing of mice with experimentally induced tumors. During healing sessions, we observed distinct magnetic fi eld oscillations adjacent to the mice cages, which were similar in appearance to those reported by Zimmerman (198...

Results from the Swarthmore Spheromak Experiment ~SSX! @M. R. Brown, Phys. Plasmas 6, 1717 ~1999!# indicate that formation and partial merging of two spheromak plasmas can be described well by a magnetohydrodynamic ~MHD! picture in which there is substantial evolution towards force free states within each vessel, while reconnection activity, also described reasonably well by MHD, occurs in the ...

Induced mutagenesis causes an increase variation of some products with limited genetic resources. In this study, the antioxidant enzymes activity, biochemical properties and glycoside content of Stevia were assessed by EMS (chemical mutagen) based on two experiments as factorial with completely randomized design with three replications. The results of the first experiment showed that some prope...
