Stiffness

That external aortic root, it will never work, you know.

So I set out to change the entire treatment for aortic dilation.

Each element is then analyzed individually to develop member stiffness equations.

This is because aortic insufficiency causes increased blood flow in the ascending aorta.

You can see two of the leaflets of the aortic valve working there.

The mechanical counterparts of these properties are, respectively, mass, stiffness and damping.

These cells normally act as special chemoreceptors located along blood vessels, particularly in the carotid bodies (at the bifurcation of the common carotid artery in the neck) and in aortic bodies (near the aortic arch).

Bentall procedure Replacement of the damaged section of aorta and replacement of the aortic valve.

It has a funny tri lobal shape at the bottom, which contains the aortic valve.

The aorta actually has the little arch like that. We call that the aortic arch.

For now, the British upper lip seems to have regained some of its stiffness.

The method described in this section is meant as an overview of the direct stiffness method.

Confusion, decreased level of consciousness or coma may be present, as may neck stiffness and other signs of meningism.

In the middle, you can see that little structure squeezing out, that's the left ventricle, pushing blood out through the aortic valve.

Trent engines use hollow titanium fan blades with an internal Warren girder structure to achieve strength, stiffness and robustness at low weight.

like Richard, or a cockroach, or a crab, or a kangaroo, the relative leg stiffness of that spring is the same for everything we've seen so far.

And then the final valve, I need to find a nice spot to write it maybe to right here, this final valve that passes through is called the Aortic valve.

In contrast to the British royal family s stiffness and reserve, she showed herself to be a princess who was also a normal human being, more like the rest of us.

Joint stiffness may be either the symptom of pain on moving a joint, the symptom of loss of range of motion or the physical sign of reduced range of motion.

If you compare our new treatment to the existing alternative, the composite aortic root graft, there are one or two startling comparisons which I'm sure will be clear to all of you.

Variations with temperature in the resonance frequency (and other features of the frequency function) are directly related to variations in the Young's modulus, which is a measure of stiffness of the material.

Translating these electrical element values back into mechanical quantities provided specifications for the mechanical components in terms of mass and stiffness, which in turn could be translated into physical dimensions for their manufacture.

For now, the British upper lip seems to have regained some of its stiffness. One hopes that this will last long enough for British society to regain its stability and its much needed vigor.

It's an observation with obvious medical applications in humans as well, but it's also relevant in a broad sense, I think, to the design of prosthetics, soft robots, basically anything where changes of shape and stiffness are important.

Brown intended this name in the same sense as the medical term ankylosis, to refer to the stiffness produced by the fusion of many bones in the skull and body, so the name is often translated as 'stiffened lizard.

What we discovered is whether you look at the leg of a human like Richard, or a cockroach, or a crab, or a kangaroo, the relative leg stiffness of that spring is the same for everything we've seen so far.

Radiation therapy Radiation may be used to treat stage 2 seminoma cancers, or as adjuvant (preventative) therapy in the case of stage 1 seminomas, to minimize the likelihood that tiny, non detectable tumors exist and will spread (in the inguinal and para aortic lymph nodes).
