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

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

However, angiography is only motion or still images of dye mixed with the blood with the arterial lumen and never show atheroma the wall of arteries, including atheroma with the arterial wall remain invisible.

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.

Besides an increase in population, another problem is vehicles overloading the network of highways and arterial streets.

On a larger level, vasoconstriction is one mechanism by which the body regulates and maintains mean arterial pressure.

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

Sometimes, for example if a patient coughs just when an embolus is passing, it might cross to the arterial system.

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

CVP reflects the amount of blood returning to the heart and the ability of the heart to pump the blood into the arterial system.

Arterial ultrasound, especially of the carotid arteries, with measurement of the thickness of the artery wall, offers a way to partially track the disease progression.

Hypertension (HTN or HT) or high blood pressure, sometimes called arterial hypertension, is a chronic medical condition in which the blood pressure in the arteries is elevated.

Respiratory failure is inadequate gas exchange by the respiratory system, with the result that levels of arterial oxygen, carbon dioxide or both cannot be maintained within their normal ranges.

The Holter's most common use is for monitoring heart activity (electrocardiography or ECG), but it can also be used for monitoring brain activity (electroencephalography or EEG) or arterial pressure.

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.

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.

The A90 is the main arterial route into the city from the north and south, linking Aberdeen to Edinburgh, Dundee, Brechin and Perth in the south and Ellon, Peterhead and Fraserburgh in the north.

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.

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.

Windkessel effect is a term used in medicine to account for the shape of the arterial blood pressure waveform in terms of the interaction between the stroke volume and the compliance of the aorta and large elastic arteries (Windkessel vessels).

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.

An analysis of arterial blood is used to determine the need for oxygen this is recommended in those with an FEV1 less than 35 predicted, those with a peripheral oxygen saturation of less than 92 and those with symptoms of congestive heart failure.

Patients are recommended for transplant if they have an arterial blood pH less than 7.3 after fluid resuscitation or if a patient has Grade III or IV encephalopathy, a prothrombin time greater than 100 seconds, and a serum creatinine greater than 300 mmol L In a 24 hour period.
