In Howard's preferred orientation, people should be judged, and held responsible, based on their good-faith efforts and tangible results rather than their legalistic compliance with precise regulatory requirements.
However, continuous presentation of this line (adaptation) eventually leads to a reduction in the response of these neurons (Figure 4d, neuron D), and to a lesser extent, neurons with a preferred orientation very close to 10[degrees] (Figure 4d, neurons C and E).
Both temperature and time affect the migration of atoms toward the preferred orientation. The behavior observed in XRD pattern could be attributed to the rate of heating which is considered much slower in conventional method than that in microwave-assisted technique that gives the needed time for the atoms to get their preferred orientation.
As compared to the CrN coating, XRD patterns of the CrCu-N coatings are mainly composed of CrN phase, and the (200) plane is the preferred orientation phase in Cr-Cu-N coatings.
The XRD pattern of all the Zn doped CdS thin films deposited at different Zn concentrations confirms the hexagonal structure with the preferred orientation along the (101) plane [14].
The multilayer webs contain fibers with a preferred orientation in machine direction but not 100% unidirectional direction [16].
The preferred orientation of the ZnO-NRs films was evaluated by the texture coefficient (TC) calculated from the XRD data using the well-known formula [31].
Most of the transverse and longitudinal fractures in the Samana Suk Formation are formed at high angles to bedding and reveals two to three discrete preferred orientation sets.
The preferred orientation, n (100), of all samples was determined by an X-ray diffractometer with a fiber specimen attachment.
XRD patterns showed various diffraction peas at 29=32,4[degrees], 35.12[degrees], 38.52 [degrees], 58.07[degrees], 60.96[degrees], 66.06 [degrees], and 67.76[degrees] that corresponds to (110) (002), (111), (020), (202), (022), and (113) according to JCPDS Card (No.051-661) [7] with preferred orientation of 2[theta]=38.52[degrees].
IPL processing improves the crystallinity keeping the (111) preferred orientation until an energy input threshold is reached.
