The reasons are that the PCB industry experiences frequent technical advances, design knowledge is separated from process knowledge, and a great variation exists among companies in processes and capabilities.
Great variation exist between each set due to differences in make, size and shape, alloy used giving each kulintang set a unique pitch level, intervals and timbre.
However, great variation exists in community composition across each of these islands.
These studies show that great variation exists in the peripheral and central mechanisms for extraction of important target features such as direction, azimuth, elevation, velocity or size that are used for related orientation behaviors.
Furthermore, a great variation exists among different paralog groups within the same gene lineage.
A great variation exists even among different paralog groups of the same gene lineage present in different species.
Great variation exists between the additional RCTs (Fig. 4) with no study achieving all of the study criteria.
In addition, great variation exists in the progression endpoints measured (e.g., progression-free survival, tumour response, local-regional relapse, and so on) and in the quality, consistency and frequency of tumour assessments.
For example, a great variation exists among different lepidopteran species with respect to their sensitivity to systemic RNAi and variable levels of silencing can occur at very different concentrations of dsRNA.
Although life history and morphological variation are pervasive between all manner of migratory and resident forms of animals, this variation is perhaps best appreciated among the salmonid (salmon, trout, and char) family of fishes, wherein great variation exists in the propensity, timing, duration, and distance of their marine migrations (Quinn and Myers 2005).
