Long test output measurement

The test foods studied here were five kinds of tomatoes. When eating food, humans first masticate the food with their teeth and then taste it. Therefore, we used a mixer in place of teeth and crushed tomatoes before measuring them. The preconditions were established by keeping the electrode immersed in standard juice, i.e., commercial canned tomato juice without NaCl added, for a long period of time. The origin of the output pattern was taken under these preconditions. Standard juice was used for the reference electrical potential pattern. The standard deviations between different lots of membrane were about 3mV. The same set of the eight membranes was used throughout the measurements for all tomatoes. 

When used properly by trained personnel, employing adequate process controls, the LAP environment provides a reliable barrier to measurable airborne viable and non-viable, solid particulate contamination, which may defeat the aseptic process. LFCBs, BSCs, and heating, ventilation, and air conditioning (HVAC) installations are easily validated. These systems normally continue in operation with little or no variation in output quality for long periods of time, and are easily maintained and tested. 

In the test, 460-mm long (1.5-ft) long, 150-m (0.5-ft) wide and up to 25-mm (1-inch) thick vertical polymer sample is used. The vertical polymer sample is placed at an angle in front of a 460-mm (1.5-ft) x 300-mm (1-ft) radiant panel. The top of the polymer sample is closer to the radiant panel, forcing the ignition near its upper edge and the flame front to progress in the downward direction. The maximum output of the radiant panel is equivalent to a black body temperature of 670 4°C (45 kW/m ). The measurements made in the test consist of ... 

Oscillatory shear flow properties (also referred to as dynamic viscoelastic properties) have long been used to investigate the viscoelastic properties of polymeric materials (Ferry 1980). Oscillatory shear flow measurement requires an instrument that can generate sinusoidal strain as an input to the fluid under test and record the stress resulting from the deformed fluid as an output. For such purposes, a parallel-plates flxture as well as a cone-and-plate flxture can be used the uniform shear rate in the radial direction that is necessary when conducting steady-state shear flow experiments is no longer necessary.
