The axial twist theory was designed to explain how the pattern of contralateral organization, [10] decussations and chiasmas develops, and why this pattern is so evolutionarily stable, [25] having no known exceptions throughout the 500 million years of vertebrate evolution. According to the theory, the contralateral organization develops as ...
The voids are positioned in the middle of the cross section, where concrete is least beneficial to the structure. The integrity of the solid layers is maintained, as the top and bottom of the slab can experience particularly high stresses. This enables the slab to effectively resist both positive and negative bending moments. [2]
The moment distribution method is a structural analysis method for statically indeterminate beams and frames developed by Hardy Cross. It was published in 1930 in an ASCE journal. [1] The method only accounts for flexural effects and ignores axial and shear effects.
In addition, reference may be made to structures at specific levels of the spine (e.g. the 4th cervical vertebra, abbreviated "C4"), or the rib cage (e.g., the 5th intercostal space). Occasionally, in medicine, abdominal organs may be described with reference to the trans-pyloric plane , which is a transverse plane passing through the pylorus .
Micrograph of thin cross-section of Chlamydomonas axoneme A simplified model of intraflagellar transport.. In molecular biology, an axoneme, also called an axial filament, is the microtubule-based cytoskeletal structure that forms the core of a cilium or flagellum.
The transverse plane (also known as the horizontal plane, axial plane and transaxial plane) is an anatomical plane that divides the body into superior and inferior sections. [1] It is perpendicular to the coronal and sagittal planes.
Commonly used structures can be classified into five major categories, depending on the type of primary stress that may arise in the members of the structures under major design loads. However any two or more of the basic structural types described in the following may be combined in a single structure, such as a building or a bridge in order ...
The stress given by this equation is exact, knowing that the cross section is not adjacent to the point of application of the load nor having holes for bolts or other discontinuities. For example, given an 8 x 11.5 plate that is used as a tension member (section a-a) and is connected to a gusset plate with two 7/8-inch-diameter bolts (section b-b):
