Sep 29 2015 · Increasingly more evidences are supporting the alternative 2/3-power scaling rule especially for smaller animals. The 2/3-rule dates back to before Kleiber s time and was thought to originate from the surface to volume relationship in Euclidean geometry. In this study we show that both the 3/4- and 2/3-scaling rules have in fact one common

Free ChatAug 12 2018 · For simplicity and clarity CAD users draw buildings at full scale. For instance when drawing a door in CAD the door would be 3 feet wide and 7 feet tall. However since these drawings get placed on sheets of paper that are much smaller a scale factor is required so that the final drawing has a usable conversion factor.

Free ChatA geometric approach to a biological problem. All the way back to the 1800 s people suspected that the scaling of size and metabolism is going to be related to the amount of heat loss experienced by an organism (since all organisms require heat to carry out their metabolic processes) and therefore metabolic rate is going to be related to how organisms lose heat as they get larger.

We ll center it-- actually so it s already actually centered at 9 negative 9. We could put this wherever we want but let s center it at 9 negative 9. And we want to scale this up by 3.

Free ChatIn scale-up practices power numbers are often determined without gassing. However gassing greatly reduces impeller torque thus having a significant impact on the apparent impeller power numbers as well as the results of aerobic processes. Maintaining constant P/V between vessels is one of the most common and prevalent strategies for scale-up.
