We present self-consistent, fully coupled two-dimensional (2D) numerical models of thermal evolution and tidal heating to investigate how convection interacts with tidal dissipation under the influence of non-Newtonian grain-size-sensit...

BACKGROUND The prevalence and prognostic importance of atrial fibrillation (AF) on survival in nonsmall breed dogs with myxomatous mitral valvular disease (MMVD) and congestive heart failure (CHF) remain unknown. AIM To identify the prevalence of AF in nonsmall breed dogs with CHF because of MMVD and to characterize the impact of AF on survival outcome. ANIMAL Sixty-four client-owned dogs (...

Currently, and throughout much of the Amazonian, the mean annual surface temperatures of Mars are so cold that basal melting does not occur in ice sheets and glaciers and they are cold-based. The documented evidence for extensive...

BACKGROUND Shoulder injuries remain one of the most common injuries among collegiate football athletes. Offensive linemen in particular are prone to posterior labral pathology. PURPOSE To evaluate the efficacy of shoulder bracing in collegiate offensive linemen with respect to injury prevention, severity, and lost playing time. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Offe...

Tendon stiffness may be involved in limiting peak musculoskeletal forces and thus may constitute an upper limit for bone strength. The patellar tendon bone (PTB) graft, which is harvested from the patellar tendon during surgical reconstruction of the anterior cruciate ligament (ACL), is an ideal scenario to test this hypothesis. Eleven participants were recruited who had undergone surgical reco...

BACKGROUND Atrophic acne scars are a common and psychologically devastating sequela of acne vulgaris that are refractory to the vast majority of topical treatments. OBJECTIVE We evaluated the efficacy of a topically applied synthetic epidermal growth factor (EGF) serum in reducing the appearance of atrophic acne scars. METHODS A single-center clinical trial was performed on nine self-select...

This article provides a political economy framework for analysing China’s engagements with Africa. It situates the rise of China in the context of the changing balance of power in the world system and particularly China’s re-entry into spheres of influence in Africa that have been the purview of the former European colonial powers for two centuries or more. It begins by arguing that current app...
