OBJECTIVE To compare biomechanical properties of currently available plating systems used to reconstruct segmental mandibular defects. DESIGN Controlled in vitro investigation. SETTING Academic medical center laboratory. INTERVENTIONS Thirty-two polyurethane mandibles were equally divided among 4 groups: mandibles with a 4-cm lateral segmental defect that was bridged with a (1) 3.0-mm loc...

Yield management has been successfully applied in the context of airline companies. However, so far, application to telecommunication industry have been scarce. Using Yield management principles, this paper investigates the new problem of maximizing revenue of telecommunications operator by setting prices on voice services. This pricing is based on available resource i.e. network load. We first...

In the light of recent studies into the impact of cognitive load on detecting deception, the impact of cognitive load on faking on the Gudjonsson Suggestibility Scale (GSS) was investigated. Eighty undergraduate students participated in the study, and were randomly assigned to one of four conditions resulting from a combination of the factors: instruction type (genuine or instructed faking, see...

BACKGROUND Despite increasing attention on fixation of a soft tissue anterior cruciate ligament graft in the tibia, there have been no studies on the use of a bone dowel as a joint line fixation device for promoting fixation properties, especially stiffness at the time of implantation. PURPOSE To determine whether compacting a bone dowel into the tibial tunnel improves fixation stiffness, yie...

PURPOSE The purpose of this study was to compare the biomechanical fixation stability conferred by 2 specific arthroscopic repair techniques for complete gluteus medius tendon tears. METHODS Twelve fresh-frozen human cadaveric hemi-pelves were tested. Six received double-row repair with massive cuff stitches (DR-MCS), whereas the remaining 6 underwent double-row repair with knotless lateral a...

In the LHC beam pipe, an electron cloud can build up due to photoemission from synchrotron radiation and via a beam-induced multipacting process. This electron cloud gives rise to an additional heat load on the beam screen which protects the cold bore of the superconducting magnets. The heat load from the electron cloud depends on beam parameters such as the bunch intensity, the number of bunch...

Forming limit diagrams (FLDs) are calculated based on both the Marciniak and Kuczynski (M-K)  model and the analysis proposed by Jones and Gillis (J-G). J-G analysis consisted of plastic deformation approximation by three deformation phases. These phases consisted of homogeneous deformation up to the maximum load (Phase I), deformation localization under constant load (phase II) and local necki...
