OBJECTIVE The objectives of these two studies were to determine if beads from extended-release topiramate capsules sprinkled onto soft food are bioequivalent to the intact capsule and if beads from the capsule can be passed through enteral gastrostomy (G-) and jejunostomy (J-) feeding tubes. METHODS Bioequivalence of 200-mg USL255 (Qudexy XR [topiramate] extended-release capsules) sprinkled o...

ntroduction: The use of a calcium solution previously to brushing could favor the remineralization and the fluoride (F) uptake in dental enamel. Objective: This study evaluated the F in dental enamel after using a F dentifrice, preceded or not by a rinse with a CaCl2 solution. Methods: Ten subjects (18-30 years) participated in a double-blind, cross-over protocol. Enamel biopsy and 3 min saliva...

Biofouling of nanofiltration (NF) and reverse osmosis (RO) membranes for water treatment has been the subject of increased research effort in recent years. A prerequisite for undertaking fundamental experimental investigation on NF and RO processes is a procedure called compaction. This involves an initial phase of clean water permeation at high pressures until a stable permeate flux is reached...

A time revolved spectroscopic study of the emission phases occurring throughout a nanosecond pulsed discharge in water is presented. Discharged are ignited in deionized water via a submerged pin-t-plane electrode configuration by application of 24kV pulses with a rise time of 4ns and a duration of 10ns. Optical emission spectroscopy of the plasma radiation is performed, revealing a very complex...

The investigations were focussed on the question as to whether roots of intact maize plants (Zea mays L. cv Blizzard) release protons into deionized H(2)O. Plants in the six to seven leaf stage depressed the pH of deionized H(2)O from 6 to about 4.8 during an experimental period of 4 hours. Only one-third of the protons released could be ascribed to the solvation of CO(2) in H(2)O. The main cou...

Electrospray was employed upstream of an electrostatic precipitator (ESP) to enhance the collection efficiency of monodisperse nanometer-sized particles. The electrospray of deionized water produced water droplets with a size range from several tens to several hundreds μm. The visible combined effect of the ESP with the electrospray was found for the collection of particles larger than about 20...
