OBJECTIVES/HYPOTHESIS To assess the complication and migration rates associated with the fixation of cochlear implant receiver-stimulators using a subperiosteal tight pocket without either suture fixation or bone recession. STUDY DESIGN Dual-institution retrospective case review. METHODS A retrospective case review was conducted at two tertiary referral centers. All patients who underwent c...

BACKGROUND Because the tension that exists in an anterior cruciate ligament graft when the knee is unloaded (the initial tension) affects the surgical outcome and because high initial tension has a number of adverse consequences, the primary purpose of this study was to determine quantitatively how much less initial tension was required for a high-stiffness construct than for a low-stiffness co...

observations, to constrain the pattern of N2 fixation across the Pacific Ocean. N2 fixation introduces isotopically light atmospheric N2 from to the ocean (d N = 0‰) relative to the oceanic average near 5‰, which makes nitrogen isotopes suitable to infer patterns of N2 fixation. Including atmospheric iron limitation of diazotrophy in the model shifts the pattern of simulated N2 fixation from th...

PURPOSE We performed a qualitative assessment of fixation behaviour in relation to the fovea in patients with strabismic amblyopia. METHODS The fixation of 25 patients with strabismic amblyopia was examined using a scanning laser ophthalmoscope (SLO). A digital frame grabber board was programmed to scan onto the patient's retina single solid black discs of 5, 10 and 15 degrees in diameter and...

A simultaneous oxidation and reduction of nitrogen is performed for fixation with a DC plasma-electrolysis operated in N 2 .

This study compares the functional capabilities of different metacarpal fixation constructs under physiological loadings in an attempt to identify the optimal construct rather than the strongest one. One hundred and twenty-six preserved human metacarpals were mechanically tested after oblique osteotomies and internal fixation. Maximum load to failure, average structural rigidity, and energ...

Tropical coral reefs are among the most productive and diverse ecosystems, despite being surrounded by ocean waters where nutrients are in short supply. Benthic dinitrogen (N2) fixation is a significant internal source of "new" nitrogen (N) in reef ecosystems, but related information appears to be sparse. Here, we review the current state (and gaps) of knowledge on N2 fixation associated with c...
