In motile fibroblasts, for instance, there are transient calcium microdomains ('calcium flickers') of ∼5 μm in diameter and 10 2000 ms in duration, a rising flicker activity gradient along the rear-to-front axis, and a shallow background calcium concentration gradient in the opposite direction.
The three-letter coding of exposure scenarios used in later sections of this paper follows WHO publications [ 15], with letter-order corresponding to field components polarisation or direction of field propagation in regard to vertical (top, bottom), transverse (right, left), or sagittal (front, back) axis of the human body.
The x-axis points to the front, the y-axis to the left and the z-axis to the top of the head.
Note also the distance between the deformation front and trench axis.
Lateral distortion can be countered by locating the front fork torsional axis as low as possible.
Two parallel rows of domed scutes ran down the top of the neck, along the anteroposterior axis (front to back).
This result showed that with the gradual increase of IOP, the stress change of anterior half of sclera, which was in front of middle axis of eyeball and approximately represented the areas around retina, was not obvious, while stress on the posterior half of sclera, which approximately represented the middle and central area of retina, becomes smaller.
In support of our theoretical predictions, we observed a preferential alignment of actin filaments perpendicular to the front-to-rear axis of stable-bleb cells, highlighting the presence of anisotropic tension within the cortex.
Conceived by the commander-in-chief of the British Middle East Command, General Archibald Wavell, Brevity was intended to be a rapid blow against weak Axis front-line forces in the Sollum Capuzzo Bardia area of the border between Egypt and Libya.
Setting up the front-to-back axis in the embryo involves a family of proteins called the bone morphogenetic proteins (or BMPs).
