Over the years a number of photorefraction systems with different grades of complexity and automation were developed.
Indeed, the successive emergence of higher grades of complexity throughout the history of life is impossible to ignore.
However, each in vitro model has its own specific advantages and disadvantages (Tiffany-Castiglioni 2004) and represents different grades of complexity and allows predictions for humans to different degrees (Table 1).
According to this view, stingless bees (Melipona) might not even possess a dance language, since they live in small, less-organized colonies (that is, they are lower on the phylogenetic grade of social complexity than honeybees).
Low and medium grade (G1/G2) tumors generally contained few changes, paralleled by similar low level of complexity in Ta tumors (Table 1).
Some of these initiatives have a degree of complexity which required explanation in addition to the traffic light grading.
"The level of complexity was incredibly high".
It's the highest grade in terms of complexity, gimmicks, detailing, scale and price.
All three pathways were characterised by different grades of technological complexity and flexibility [10],[11], as well as different production configurations, shown in Figure 2. Figure 2 Overview of biofuel conversion pathways (adapted from [[5]]).
Multivariable analysis including the significant variables of age, ASA grade, and complexity of procedure, estimated that the hazard of death was 1.64 (1.33 to 2.02) times higher for the cemented group and 1.47 (1.19 to 1.82) times higher for the uncemented group when compared with Birmingham hip resurfacing (table 5).
Multivariable analysis showed that procedure type, age, sex, ASA grade, and complexity of procedure were all significant and were thus included in the final model.
