This paper documents the changing patterns of corporate interlocking among approximately 250 corporations across four time periods—1962, 1973, 1983, and 1995. By utilizing network analyses, we describe several attributes of the overall set of interlocking corporate directors in a period of increasing corporate concentration, economic globalization, and changing regulatory environments. Measures...

Our clinical experience with interlocking detachable coils for the embolization of high-flow dural arteriovenous fistulas is reported. Interlocking detachable coils are useful for transarterial and transvenous embolizations of dural arteriovenous fistulas because (a) immediate coil detachment is possible, (b) the coils can be replaced easily, (c) detached coils rarely migrate, and (d) fewer int...

OBJECTIVE To investigate the effects of using intramedullary reaming to provide cancellous bone graft, and reamed intramedullary nail stabilisation to provide fragment stability on treating tibial shaft aseptic nonunions after plating. METHODS 31 consecutive patients with tibial shaft aseptic nonunions after plating were prospectively treated. Indications for this technique included a tibial ...

Statically locked, reamed intramedullary nailing remains the standard treatment for displaced tibial shaft fractures. Establishing an appropriate starting point is a crucial part of the surgical procedure. Recently, suprapatellar nailing in the semi-extended position has been suggested as a safe and effective surgical technique. Numerous reduction techiques are available to achieve an anatomic ...

A review of the literature in 2002, analyzing 13 articles with 895 tibial shaft fractures treated by cast immobilization, fixation with plate and screws, and reamed or unreamed intramedullary nailing, concludes that the combined incidence of delayed union and nonunion was lower with operative, surgical treatment especially with plate osteosynthesis, than with closed treatment. This incidence wa...

It has been suggested that reamed intramedullary nailing of the femur should be avoided in some patients with multiple injuries. We have studied prospectively the effect of femoral reaming on the inflammatory process as implicated in the pathogenesis of acute respiratory distress syndrome (ARDS) and multiple-organ failure (MOF). We studied changes in the levels of serum interleukin-6 (IL-6) (pr...

The framed structure infilled with a mortarless brick (MB) panel exhibits considerable in-plane energy dissipation because of the relative sliding between bricks and good out-of-plane stability resulting from the use of interlocking mechanisms. The cyclic behaviors of MB are investigated experimentally in this study. Two different types of bricks, namely non-interlocking mortarless brick (N-IMB...

T o a large extent, the eld of “molecular machines” started aer several groups were able to prepare reasonably easily interlocking ring compounds (named catenanes for compounds consisting of interlocking rings and rotaxanes for rings threaded by molecular laments or axes). Important families of molecular machines not belonging to the interlocking world were also designed, prepared and studied ...
