This paper is an introductory guide to many-particle hydrodynamic interactions. Basic concepts of the fluid mechanics are assumed to be known. Experience in the Stokes equations is useful but not necessary. The study is estimated to fit five sessions about three hours each.

BACKGROUND AND PURPOSE The vestibular nucleus cannot be visualized on MR imaging, but some patients with vestibular schwannoma show a tiny area of hyperintensity in the dorsal brain stem on T2-weighted images. The aim of this study was to determine whether this tiny area is characteristic of vestibular schwannoma. METHODS We retrospectively reviewed the postoperative MR images of 53 patients ...

Protostars likely accrete material at a highly time variable rate, however, measurements of accretion variability from the youngest protostars are rare, as they still deeply embedded within their envelopes. Sub-mm/mm observations can trace thermal response dust in envelope to luminosity changes, allowing variations rate be quantified. In this paper, we present contemporaneous sub-mm/mm light cu...

The effect of orally administered prostaglandin 15(R)15 methyl-E2 methyl ester on aspirin and taurocholic acid-induced gastric mucosal haemorrhage has been studied in rats. The incidence of haemorrhage induced by aspirin (26-7 mM), 64 mg/kg, together with taurocholic acid (2-5 mM), was significantly reduced from 53-6% to 19-5% by the addition of the prostaglandin (9-9 muM), P less than 0.01. Th...

The accelerating trend toward Faster, Better, Cheaper (FEE) missions places increasing emphas is on the trade-offs between requirements and risk to reduce cost and development times, while still improving quality and reliability. The Risk/Requirenlents Trade-off Guidelines discussed in this paper are part of an integrated approach to address the main issues by focusing on the sum of prevention,...

A Holocene lake sediment record spanning the past 7300 years from Wishart Lake in the Turkey Lakes Watershed in the Hemi-Boreal of central Ontario, Canada, was used to evaluate the potential drivers of long-term change in diatom assemblages at this site. An analysis of diatom assemblages found that benthic and epiphytic taxa dominated the mid-Holocene (7300-4000 cal yr BP), indicating shallow, ...
