The most obvious cause of an anal fissure is direct trauma to the anal canal. Childbirth, anal intercourse, and insertion of any foreign bodies into the anal canal can cause a fissure. Chronic constipation and chronic diarrhea can also cause an anal fissure by repeatedly straining the lining ...

BioMedical Engineering OnLine 2021, 20(1): Page 33 of 39 Literature data of muscle tissue stiffness measured using elasticity imaging Figure 21 contains supplementary data on Shear Moduli G besides the data on Young's moduli E from Fig. 5. Detailed information, including the type of ...
How the stiffness of meniscal attachments and meniscal material properties affect tibio-femoral contact pressure computed using a validated finite element model of the human knee joint. J Biomech 2003;36:19-34.͓25͔ Haut Donahue, T. L., Hull, M. L., Rashid, M. M., and Jacobs, ...
Of course, keeping people safe in auto accidents isn't as simple as making the whole vehicle crumple. Engineers have to consider many factors in designing safer cars, including vehicle size and weight, frame stiffness and the stresses the car is likely to be subjected to in a crash. For ex...
Like a physical media brush, the Bristle brush diameter is measured at the point where the bristles meet the handle (the ferrule). Specify the brush size using the slider or directly entering the size in the available text field. Range can be between 1mm and 10mm. Brush size from the ...
Stiffness after total knee replacement () is a frustrating complication that has many possible causes. Although the definition of stiffness has changed over the years, most would agree that flexion <75° and a 15° lack of extension constitutes stiffness. The management of this potentially unsatisfy...
Since organza is so lightweight, its quality is measured in terms of holes per inch (HPI) rather than thread count. To obtain this measurement, the number of holes in every square inch of this fabric are counted, and the higher the HPI rating, the better the quality of the organza ...
afixedbase structures. As stated before, α0 is an index for the structure-to-soil stiffness ratio that controls the severity of SSI effects, and also the value of 3 for this parameter is representative of the system in which the SSI effect is predominant for common building structures. The...
torque. For example, when you put a lug wrench onto a bolt and then attempt to tighten it, you are applying reaction torque to it. Even if the bolt doesn’t turn much or at all, the reaction torque is still present. In this case, torque is being measured in less than one ...
