Extraction using 10 g of diluted (5% w/w) blended soursop pulp with CAR/PDMS fiber at 25 °C for 30 min and 30% (w/w) of NaCl under stirring mode resulted in the highest extraction efficiency of volatile flavor compounds.
The pH was later adjusted using 1 M HCL and NaOH to reach the desired value while keeping the solution in stirring mode to promote homogenized chemical reaction.
Subsequently, the tubes were immersed in a water bath at 70°C for 1 h under stirring mode.
In a typical procedure, H2SO4 and H3PO4 with 320: 80 ml ratio along with 3 g of graphite were mixed in a 2-l beaker under stirring mode.
To this end, chondrocyte-seeded agarose constructs (∅10 mm, 2.34 mm thick), with zero or three nutrient channels (∅1 mm), were suspended on their sides in custom culture racks and subjected to three media stirring modes for 56 days: uniaxial rocking, orbital shaking, or static control.
This module uses the Ornstein-Uhlenbeck process (Uhlenbeck and Ornstein 1930) to generate stirring modes in Fourier space.
Four different variables were tested here: the liquid desorption mode (stirring or sonication), the chemical nature of the stir bar (PDMS or PDMS-PEG), the composition of the liquid desorption phase and finally, the volume of solvent used for the liquid desorption.
A 25 1 fractional factorial design was performed to assess the influence of several factors (type of fiber coating, sampling mode, stirring, extraction temperature, and addition of sodium chloride) on the SPME procedure and to determine the optimal extraction conditions.
Based on an examination of the design parameters one by one, the best cadmium removal was achieved for an inter-electrode distance (die) of 0.5 cm, monopolar connection mode, stirring speed of 300 rev min−1, surface-area-to-volume ratio (S/V) of 13.6 m−1, and an initial temperature of 50 °C.
An artist with a lot of goodwill, Murphy's solo albums were well received, and attempted to move things on, but for all the couture madness of her presentation, they seemed locked into some familiar modes: stirring Massive Attack-style symphonic beats, or chirpy drivetime house.
At first the fermentation was run in batch mode with dissolved oxygen level maintained at required saturation (pO2) by using filtered air and with stirring speed in cascade mode in order to achieve and keep pO2 level constant.
