In addition to the primary specification, I estimate models including shared individual and firm frailties, models comparing voluntary vs. involuntary separations, and models with alternative hazard specifications.
The primary specification is that the "objective is not only to acquire knowledge" but also to contribute "to the solution of a concrete practical problem" (ibid).
Designing in this way raises the level of abstraction of the primary specification, allowing designers to explore the architectural trade-offs and hardware/software partition decisions that need to be made at a higher level.
Given the very low yields and the resulting limitations to accurate measurement of extracted RNA for many samples, acceptance criteria for the assay include a specification of the average of the reference genes rather than on mass of RNA input as the primary specification for sample quality.
All five introductory majors texts sampled included all (n = 51) or all but one of the primary MCAT content specifications, that is, those with MIRs determined through AAMC's surveys of MCAT stakeholders.
All texts sampled include their main discussion of at least 50% of the primary MCAT biology content specifications within the first 30% of the text.
Although XML is the primary model for this specification, other formats are also possible, such as JavaScript Object Notation (JSON).
Rather than centromeric sequences, the primary candidate for epigenetic specification of centromeres is the histone variant CENP-A, which replaces canonical H3 in centromeric nucleosomes (Palmer et al., 1987, 1991; Stoler et al., 1995; Henikoff et al., 2000; Yoda et al., 2000).
Auto-ignition temperature (AIT) of a flammable material is the primary characteristic in determining the specifications of these explosion-proof equipments.
