link of the repair. In particular, the principles for tying a knot with high security and strength should be a basic standard for every orthopedic surgeon. In the following, the essential basics of knot mechanics, knot technology, nomenclature, and tissue behavior will be discussed. Author inform...
For example, if the institution offering the account is also the vendor providing the goods to be purchased, the consumer must trust the institution to deliver quality products at reasonable prices, and not take advantage of a locked-in consumer. In our setup, the voucher (i.e., the ...
First, the knot has to be sufficiently tight in order to extend the strain interval where the fiber experiences a relatively high stress. Second, this must be able to unfasten as the fiber opposite ends are pulled apart, in order to not affect the fiber fracture strength. Reference values ...
The process that organizations must go through in order to attain a code involves a variety of difficult decisions. In this article we will, based on our experiences, describe twelve dilemmas which will have to be 'solved' during the development of such a code. When...

presence of a knot the knotted region must be restricted to a single blob. Thus by increasing f we effectively consider systems with decreasing values of N [18], and we may assume that N k ∼ N t b . By considering finite size effects in force-separation ...
The formation of (α4β4)2 species from α4β4 rings suggests that these RNR rings must be flexible or come apart. To explore this issue, we analyzed EM images of α2 and β2 (150 nM) in the presence of inhibitor dATP (50 μM). At these low protein concentrations, no (α4β4...
Zhang Zhenhao is one of the students in this class. “The lion dance is cool,” Zhang says. “But it is not easy to be a good lion dancer. Look at my lion head. It’s about 10 kg. It’s hard for a young boy toliftit.” However, after three years of learning, now Zhang is...
in order to form the suture or ligation, the thread must be pulled out with forceps or the like through one of the trocar tubes to the outside of the body in order to form a knot, which then must be passed back through the trocar tube to place the knot where it needs to be inside...
In other embodiments, body 12 may be formed from a length of material whose ends 12a, 12b can be reversibly closed and opened such as by a buckle, clasp, button, snap, pin, or the like. For purposes of illustration, body 12 is shown as a closed loop that must be severed to be ...
