Abstract:
Tropic responses in plants have usually been studied by measuring changes in the deflection angle of the organ tip. However, the measurement of other geometric parameters, such as curvature along the entire length, may give us better understanding of tropic responses, particularly in shoots. Here, we describe methods for obtaining quantitative measurements of local curvature and other parameters based on digital images of bending Arabidopsis hypocotyls using the free software packages, ImageJ and R.

Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

Perpendicular-Axis Theorem
Consider a circular disc of mass M and radius R lying along an x-y plane. The origin lies at the center of the disc, and the z-axis is perpendicular to the disc's plane. All three axes coincide at the disc's center. The moment of inertia of this...
