In this paper the ratcheting behavior of carbon steel(ASTM A106B) and stainless steel(304L) elbows is studied under steady internal pressure and in-plane external moments at frequencies typical of seismic excitations. The finite element analysis with the nonlinear isotropic/kinematic (combined) hardening model has been used to evaluate ratcheting behavior of the elbows. Material parameters have...

Previous work involving Born-regulated gravity theories in two dimensions is extended to four dimensions. The action we consider has two dimensionful parameters. Black hole solutions are studied for typical values of these parameters. For masses above a critical value determined in terms of these parameters, the event horizon persists. For masses below this critical value, the event horizon dis...

1 This study presented a model-based image-matching (MBIM) motion analysis 2 technique for ankle joint kinematic measurement. Five cadaveric below-hip 3 specimens were manipulated through a full range of ankle joint motions in bare-foot 4 and shoed conditions. The ankle motions were analyzed by bone-pin marker-based 5 motion analysis and MBIM motion analysis techniques respectively. The root me...

We compare mean-link and average plaquette tadpole renormalization schemes in the context of the quarkonium hyperfine splittings in lattice NRQCD. Simulations are done for the three quarkonium systems cc̄, bc̄, and bb̄. The hyperfine splittings are computed both at leading and at next-to-leading order in the relativistic expansion. Results are obtained at a large number of lattice spacings. A numb...

Analyses of remote sensing data, surface observations and output from a regional atmosphere model point to new records in 2010 for surface melt and albedo, runoff, the number of days when bare ice is exposed and surface mass balance of the Greenland ice sheet, especially over its west and southwest regions. Early melt onset in spring, triggered by above-normal near-surface air temperatures, con...

Characteristics of the spreads of platelet-rich plasma (PRP) are not widely known despite commonly use. This study aims to evaluate whether PRP stays within the injected area by using ultrasonography, to improve understanding of the spreads of intratendinous injected PRP. Thirty-nine patients (15 males, 24 females; mean age, 49.3 years), who had symptoms on their elbows (> 6 months) and diagnos...

Long-term clinical and radiographic outcomes of primary resection for Mason type III radial head fractures were evaluated in 13 patients (14 elbows) with a mean age of 38.8 years (range, 20-67 years) at the time of surgery. All patients had isolated radial head fractures without associated injuries. Mean follow-up was 14.7 years (range, 9-26 years). Proximal migration of the radius and the carr...

OBJECTIVE To describe medial humeral epicondylitis in cats based on radiographic, anatomic, and histologic observations. STUDY DESIGN Prospective cohort study. ANIMALS Feline cadavers (n = 60). METHODS Extended craniocaudal, and extended and flexed mediolateral radiographic projections were taken of both elbows of 60 consecutive European shorthair cats that died or were euthanatized. Elbo...

PURPOSE From 1993 to 1999, 17 patients (18 elbows) underwent the Garden procedure for clinically diagnosed tennis elbow. Non-operative treatment was ineffective for these patients. METHODS The study group consisted of 10 men and 7 women, with a mean age of 49.6 years. Follow-up duration ranged from 18 months to 6 years, with a mean of 37 months. Patients' pain, activity level, and hand grip s...
