We compared the bulking and tensile strength of the Pennington modified Kessler, Cruciate and the Savage repairs in an ex vivo model. A total of 60 porcine tendons were randomised to three groups, half repaired using a core suture alone and the remainder employing a core and peripheral technique. The tendons were distracted to failure. The force required to produce a 3 mm gap, the ultimate stre...

Materials and methods: Data were evaluated from 41 patients that underwent surgical repair for acute Achilles tendon ruptures with these 2 diff erent surgery methods. In the fi rst group, which included 21 patients (19 male, 2 female; mean age: 36.8 years; age range: 22 to 49), we performed augmentation with the plantaris tendon aft er an end-to-end primary repair with a modifi ed Kessler techn...

We describe further improvements of the ηT pairing algorithm in characteristic three. Our approach combines the loop unrolling technique introduced by Granger et. al for the Duursma-Lee algorithm, and a novel algorithm for multiplication over F36m proposed by Gorla et al. at SAC 2007. For m = 97, the refined algorithm reduces the number of multiplications over F3m from 815 to 692.

Our aim was to compare the biomechanical properties of suturing methods to determine a better method for the repair of lacerated skeletal muscle. We tested Kessler stitches and the combination of Mason-Allen and perimeter stitches. Individual stitches were placed in the muscle belly of quadriceps femoris from a pig cadaver and were tensioned mechanically. The maximum loads and strains were meas...

This paper considers the role of norms within networks by describing how BP Exploration out-sourced its information technology (IT) function a major business activity. This outsourcing venture led to an attempt to create a network rather than to use a “market” form of organization. However, in some ways this attempt was found to have failed. It is suggested here that central to the effective fa...
