The study will be terminated when the participant reaches skeletal maturity, defined as less than 1.0 cm growth of body height in 6 months, or if the curve progresses more than 6 degrees, compared to the primary x-ray, seen on two consecutive spinal standing x-rays taken with 6 months interval.
Because body hair grows more slowly than head hair, a 1 1⁄2 inch (3.8 cm) sample of body hair can represent an even longer detection window than a sample from the head.[14].[14]
This limits evaluation to 10 25 cm of the body, depending on the axial field of the scanner used and negates the whole body screening advantages of modern PET scanners or necessitates an additional whole body study be performed after completion of the dynamic scan.
Using the DNeasy® Blood & Tissue kit (Qiagen, Hilden, Germany) we followed the instructions given to extract DNA from animal tissues and used approximately 1 × 1 cm of the body wall from one individual.
This means calculating the distance from the CM of the aggregate body to each segment's CM and the necessary orientation change.
The total moment of inertia is then given by summing the moments of inertia of each segment about the CM of the aggregate body.
Within and between these two size groups there was no detectable difference in the scaling exponents (slopes) relating metabolic (Emet) and mechanical costs (Emech, CM) of locomotion to body mass (Mb).
We formed 24 outbreeding pairs differing in relative body size distance by taking nuptially colored individuals of each sex from family tanks, measuring their standard length, and sorting males (range: 4.9 7.5 cm) in descending and females (range: 3.4 5.0 cm) in ascending order of body size.
Females are noticeably smaller, with a shoulder height of 73-84 cm, a body length of 121-141 cm, and a weight of 17-32 kg.
