UNLABELLED The purpose of this cadaver study about the ACL graft was to compare a "Lateral Tibial Tunnel" (LTT) and a "classic, anteroMedial Tibial Tunnel" (MTT), as to fixation strength and mode of failure. Ten pairs of fresh frozen human proximal tibias were used. In one of both tibias a classic anteromedial tunnel was used, versus a lateral tibial tunnel in the contralateral knee. Autologous...

The surprising incidence of nonlethal skeletal fractures implies that many organisms operate near their upper performance limits, yet we know little about the loads at which biological structures break or about the material properties of those structures. In addition, biologically realistic estimates of how closely normal maximal loads approach breaking strengths (i.e., safety factors) remain e...

Two experiments conducted on laying hens, aged 50 and 52 weeks, were carried out to evaluate the effect of dietary Mg and its relationship to the Ca : NPP (non-phytate phosphorus) ratio using a various grain-size of limestone. The Ca : NPP ratio in each experiment was 12.8 and 18, respectively. Two Mg levels were evalued in the first (1.56 and 4.0 g/kg) and the second experiment (1.52 and 4.0 g...

We show that the Einstein-Hilbert action for the gravitational field can be derived as a linear low-energy approximation for the dynamical massless fields in the theory with the lagrangian quadratic in the gauge field strength-tensor of spin connection under the spontaneous breaking of symmetry by a vacuum state with nontrivial background strength-tension.

BACKGROUND Anastomotic dehiscence and leaks are major problems in gastrointestinal surgery and result in increased morbidity and mortality. The ideal device to create anastomoses should ensure good serosal apposition without requiring either transgression of the bowel wall or the presence of foreign material for an extended period of time. OBJECTIVES The aim of this experimental study was to ...

Scale invariant theories which contain (in 4−D) a four index field strength are considered. The integration of the equations of motion of these 4− index field strength gives rise to scale symmetry breaking. The phenomena of mass generation and confinement are possible consequences of this.

We show that the Einstein-Hilbert action for the gravitational field can be obtained as a linear low-energy approximation for the dynamical massless fields in the theory with the lagrangian quadratic in the gauge field strength-tensor of spin connection under the spontaneous breaking of symmetry with a vacuum state described by an ansatz for nontrivial background strength-tension.

The FAIRS experiment took place aboard R/P FLIP from 15 September to 15 October 2000 approximately 120 nautical miles off Monterey, California. Our approach was to use both the passive and the active infrared techniques to determine the extent to which our laboratory findings are relevant to the field. Over the past several years, we have used these techniques to investigate wave breaking on sp...

A gas decompression technique was used to determine the breaking strength of cell walls of single cells. Breaking strengths of the bacterium Salmonella typhimurium and the unicellular green alga Chlamydomonas eugametos were 100 and 95 atmospheres, respectively, while those of sporophytes of the water mold Blastocladiella emersonii were 65 atmospheres, and those of suspension cultured cells of c...
