We characterize a mechanism of injury, injury pattern, and treatment algorithm for adductor pollicis myotendinous injuries in 2 professional baseball players. Similar to myotendinous eccentric injuries in other anatomical areas, the adductor pollicis sustains a sudden forceful eccentric load during a jammed swing, resulting in intramuscular strain or tendon rupture. Based on the reported injury...

A 35-year-old man visited us with a chief complaint of painful swelling of the finger. A physical examination revealed a palpable mass, measuring approximately 2 cm × 1 cm, on the dorsoradial side of the base of the middle phalanx of the right index finger (Fig. 1A). Upon history taking, we found that the mass had formed 7 to 8 years before and had since grown slowly. The mass had a firm, hard,...

Long links on eccentrically braced frames (EBF) have lower performance than short and intermediate links. Failure of long occurs faster that medium due to the influence bending moment, which is more dominant at ends link shear forces. The objective this research improve by delaying failure buckling fracture flange web ends. According AISC 341, cross-sectional capacity outside beam greater link....

Rotating coils constitute a type of electrical transformers used to produce alternating voltage pulses exploiting the phenomenon of electromagnetic induction. In this study, we investigate the influence of the electromagnetic scattering from a metallic obstacle located inside the moving component. In particular, a perfectly conducting spherical core is positioned eccentrically inside a thin cir...

Eye movements of monkeys were recorded while they performed a visual discrimination task before and after superior colliculus (SC) lesions or control surgery. The monkeys with SC lesions were impaired in orienting their eyes toward the visual stimuli when they were presented eccentrically 15 degrees to 32 degrees from the center of the display screen, toward which their heads were directed. Thi...

While the disks are initially rotating eccentrically, the unsteady flow caused by their oscillations in their own planes and in the opposite directions is studied. The analytical solutions to the problem are obtained for both small and large times, and thus the velocity field is determined for every value of time. The variations of all the parameters on the flow are scrutinized by means of the ...
