Remitting seronegative symmetrical synovitis with pitting edema (or sometimes RS 3 PE) is a rare syndrome identified by symmetric polyarthritis, synovitis, acute pitting edema (swelling) of the back of the hands and/or feet, and a negative serum rheumatoid factor. [2]
Shrink-fitting is a technique in which an interference fit is achieved by a relative size change after assembly. This is usually achieved by heating or cooling one component before assembly and allowing it to return to the ambient temperature after assembly, employing the phenomenon of thermal expansion to make a joint. For example, the thermal ...
A bowstring joins the two ends of the bow stave and launches the arrow. Desirable properties include light weight, strength, resistance to abrasion , and resistance to water. Mass has most effect at the center of the string; one gram (0.035 oz) of extra mass in the middle of the string slows the arrow about as much as 3.5 grams (0.12 oz) at the ...
Even as vendors touted advantages of more complicated prostheses over simple peg legs, [3] according to a contemporary surgeon, many patients found a peg leg more comfortable for walking. [4] According to medical reports, some amputees were able to adjust to the use of a peg leg so well that they could walk 10, or even 30, miles in one day.
A Dutch bracer from the late 16th century, made of ivory and intricately decorated . A bracer (or arm-guard) is a strap or sheath, commonly made of leather, stone or plastic, that covers the ventral (inside) surface of an archer's bow-holding arm.
The first three combat types make up a "Combat Triangle", which governs effectiveness of styles in a rock-paper-scissors fashion; melee beats ranged, ranged beats magic, magic beats melee, and each style is neutral to itself. [33] Necromancy is a standalone method of combat and is neutral to the other styles.
They are also less expensive and easier to fit, and are the normal finger-protection used with recurve bows. The tab usually has a retaining loop on the back of the tab that fits over the middle finger, which is simply there to keep the tab on the fingers when the string is loosed.
Less powerful bows require arrows with less dynamic spine. (Spine is the stiffness of the arrow. [14]) Less powerful bows have less effect in deforming the arrow as it is accelerated (see Euler buckling, case I) from the bow and the arrow must be "easier" to flex around the riser of the bow before settling to its path.
