The author reviews the literature on occult blood surveillance for colorectal carcinoma. The
guaiacbased Hemoccult (SmithKline Diagnostics, Sunnyvale, Calif.) test is the most reliable …

A new code for astrophysical magnetohydrodynamics (MHD) is described. The code has
been designed to be easily extensible for use with static and adaptive mesh refinement. It …

OBJECTIVE: Our aim was to examine the predictive value of the Rome criteria and absence
of so-called “red flags” of clinical practice for diagnosing irritable bowel syndrome. Red flags …

She is a licensed psychologist with years of experience working with children, adolescents, …

We study the formation of planetesimals in protoplanetary disks from the gravitational collapse
of solid over-densities generated via the streaming instability. To carry out these studies, …

Turbulence can transport angular momentum in protoplanetary disks and influence the growth
and evolution of planets. With spatially and spectrally resolved molecular emission line …

Gas kinematics are an important part of the planet formation process. Turbulence influences
planetesimal growth and migration from the scale of submicron dust grains through gas-…

Turbulence is a crucial factor in many models of planet formation, but it has only been directly
constrained among a small number of planet-forming disks. Building on the upper limits on …

Turbulence is a fundamental parameter in models of grain growth during the early stages of
planet formation. As such, observational constraints on its magnitude are crucial. Here we …

We study how the structure and variability of magnetohydrodynamic (MHD) turbulence in
accretion discs converge with domain size. Our results are based on a series of vertically …
