arterial tension
blood pressure within an artery.
tension band wires
heavy gauge wire is inserted in fracture fragments and around pins placed in the fragments in order and adjusted to create compression on the fracture site. Suited for treatment of apophyseal or epiphyseal avulsion fractures. See also tension band plate.
intraocular tension
intraocular pressure; intraocular tension, normal intraocular tension being indicated by Tn, while T + 1, T + 2, etc. indicate increased tension, and T − 1, T − 2, etc. indicate decreased tension.
tension line
the direction of pull on the skin in any given region. A map of the body, drawn to show the various lines of pull, or tension, is useful in planning surgical closure of skin incisions, particularly ones with defects, in order to minimize forces that might cause dehiscence.
surface tension
tension or resistance that acts to preserve the integrity of a surface.
tissue tension
a state of equilibrium between tissues and cells that prevents overaction of any part.

Patient discussion about tension

Q. What are the symptoms of tension and migraine headaches? I get a lot of headaches and wanted to know if there is a way to tell if I am having migraines or regular tension headaches.

A. Check out this website, its all about headaches and migraines:

Q. i feel huge tension when i am in close narrow environment , is it a phobia?

A. Yes, it may be considered a phobia, or more specifically situational type phobia. However, the important thing is whether is this fear reasonable? Do you think it's out of proportion? Phobia is a fear that one perceive as irrational and out of proportion and yet one feels and is affected adversely by it. If this fear is appropriate (e.g. fear of falling in mountain climbing) it's not a phobia.

Goss is a good place to start tracing the evolution of tensioning systems.
In addition to running belt tensioning, on its four-high color press units, Goss also provides a device for controling tension on the outfeed.
In making its own decision, Pacific Press, publisher of the 188,000-circulation Vancouver Sun and 161,000-circulation tabloid Province in British Columbia, leaned towards tensioning systems that do not use belts and do have a dedicated infeed control, says Jack Ferguson, director of production for the Southam chain.
We spent a lot of money developing tensioning systems," says Doug Lang, MAN Roland's inside sales manager.
With the tensioning system, waste is dramatically lower, he says.
Bseiso adds "We use post tensioning in buildings to give us a reduced floor thickness, which is much less than the conventional method.
Bseiso adds, "Through post tensioning you lower the amount of steel used in a structure, namely rebar reinforcement, and you also lower the amount of concrete needed.
Also, post tensioning concrete floor slabs accelerates construction cycles through simplified formwork systems
Part of the appeal of post tensioning is the ability to modify the structure of the work at a later date.
The post tensioning works were already completed, but we were given new architectural requirements, including change in area use, and a change in design of the roof canopy, meaning some of the post-tensioned slabs required additional strengthening.
For a method that is essentially strengthening concrete with steel, post tensioning patently requires a high level of knowledge to properly install, maintain and modify.
