Muscle contraction as a reflection of anxiety. Most headaches are caused in this way. Tension, and associated symptoms, can often be relieved by formal relaxation procedures.

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:
http://headaches.about.com/od/headpain101/a/what_is.htm

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.

For the circular saw blade after the tensioning process, natural frequencies for the nodal circle (Nc) = 0 and nodal diameter (Nd) < 2 generally are decreased slightly.
Tangential tensile stress is produced in the edge of a circular saw blade after the tensioning process.
To summarize, the natural frequency and tangential tensile stress in the edge of a circular saw blade are two important indicators for tensioning effect, and are also the basis for the optimization of a multispot pressure tensioning process.
F, M, N, [R.sub.w], and d influence the tensioning effect.
Tables 5 through 9 were obtained by this method, which allows us to compare the degree of influence of these factors on tensioning effect comprehensively and find the optimized scheme for a multispot pressure tensioning process.
The tensioning effect is enhanced with the decrease of [R.sub.w].
The tensioning effect is enhanced with their increase in a small range.
There are two schemes for the optimization of a multispot pressure tensioning process, as shown below.
As shown in Table 10, the two schemes for the optimization of a multispot pressure tensioning process could obtain both reasonable natural frequencies and average tangential tensile stress in the edge of the circular saw blade.
Considering the natural frequency and tangential tensile stress in the edge of the circular saw blade synthetically, optimal process parameters for multispot pressure tensioning were obtained based on the orthogonal method.
