The main-start/main-end sides determine where to start placing flex items within the flex container, starting from the main-start end and going to the main-end end. Order Places elements in groups and determines which order they are to be placed in within the container. Flex-flow Shorthands flex-direction and flex-wrap to place the flex content.
q is a function of a point, an area, and a direction (given by a unit vector ^), and measures the flow through the disk of area A perpendicular to that unit vector. I is defined picking the unit vector that maximizes the flow around the point, because the true flow is maximized across the disk that is perpendicular to it.
Sink flow is the opposite of source flow. The streamlines are radial, directed inwards to the line source. As we get closer to the sink, area of flow decreases. In order to satisfy the continuity equation, the streamlines get bunched closer and the velocity increases as we get closer to the source. As with source flow, the velocity at all ...
Anterograde and retrograde flow refer to movement of blood or other fluids in a normal (anterograde) or abnormal (retrograde) direction. [23] Circumduction is a conical movement of a body part, such as a ball and socket joint or the eye. Circumduction is a combination of flexion, extension, adduction and abduction.
Timelines are the lines formed by a set of fluid particles that were marked at a previous instant in time, creating a line or a curve that is displaced in time as the particles move. By definition, different streamlines at the same instant in a flow do not intersect, because a fluid particle cannot have two different velocities at the same point.

Most compound flexure designs are composed of three fundamental types of flexure: [2] Example compound flexure design with nested linkage [3]. Pin flexure - a thin bar or cylinder of material, constrains three degrees of freedom when geometry matches a notch cutout
The magnetic flux is the net number of field lines passing through that surface; that is, the number passing through in one direction minus the number passing through in the other direction (see below for deciding in which direction the field lines carry a positive sign and in which they carry a negative sign).
