Multidirectional

Inflated Diaphragm Method (ASTM D3886). This method is appHcable both to woven and knitted fabrics. The specimen is abraded by mbbing either unidirectionally or multidirectionally against an abradant having specified surface characteristics. The specimen is supported by an inflated mbber diaphragm under a constant pressure. Evaluation of abrasion resistance can be either by determination of the number of cycles required to wear through the center of the fabric completely or by visual examination of the specimens after a specified number of cycles. 

Ocular Effects. Vision was blurred in 15 of the 23 workers examined as a result of intermediate-or chronic-duration inhalation exposures to high blood concentrations (in excess of 2 pg/L) of chlordecone during its production. The effects on vision were characterized by a disruption of ocular motility following a horizontal saccade by rapid random multidirectional eye movements. Visual acuity and smooth eye movements were unaffected (Taylor 1982, 1985). The rapid eye movements were probably due to disturbance of the brain stem. 

The use of a negative control group (i.e., placebo or vehicle) is a requirement. In particular, effects of novel vehicles should be assessed since it is recognized that pharmacological properties of some vehicles may interfere with the activity of the NCEs and compromise with the interpretation of the results. The use of a positive control in each study may not be practical based on the need to demonstrate multidirectional changes in a multitude of parameters as possible outcomes of administration of the NCE. This concern has been addressed in the ICH S7A guidelines that does not require the use of a positive control in each in vivo study, but rather by demonstrating that the in vivo model has been fully characterized.25 One situation, however, where a positive control may be...

Similarly, Fig. 3.30 shows measurements of i(N02) at an altitude of 7-7.5 km as a function of solar zenith angle compared to a multidirectional model calculation (Volz-Thomas et al., 1996). The agreement in this case is generally good. However, this is not always the case. For example, Fig. 3.31 shows some measurements of 7(N02) as a function of solar zenith angle made by different groups at different locations and using different techniques (Kraus and Hofzumahaus, 1998). 

Akron and the improved Lamboume are distinctive for the ability to vary slip angle in a simple manner and the Schiefer for giving uniform multidirectional abrasion. Probably the most versatile commonly used apparatus is the Taber because of the very wide range of abradants readily available and its ability to operate with lubricants. The LAT 100 is in a class of its own as regards sophistication and features. 

Surface destructive alterations around the action site of the indenter are used to determine the degree of brittleness of a material (Section 6.3). They are the outcome of a destructive deformation of the crystal induced by multidirectional shear forces released in the crystal structure. The shear stresses liberated in static indenter tests are significantly in excess of those registered under other methods, being of the order of 50 MPa (Yushkin,... 

Ya.B. s studies of combustion and detonation are diverse and multidirectional. They include the chemical thermodynamics of combustion, propagation of exothermic chemical transformation fronts, deflagration and detonation theory, thermo-diffusion and chemo-kinetic processes in combustion and at high temperatures in general, and gasdynamics of flows in the propagation of non-uniform flame fronts and in detonation.
