We present a calculation of the sedimentation of grains in a giant gaseous protoplanet such as that resulting from a disk instability of the type envisioned by Boss (1998). Boss (1998) has suggested that such protoplanets would form cores through the settling of small grains. We have tested this suggestion by following the sedimentation of small silicate grains as the protoplanet contracts and ...

Two known results in multiple testing, one relating to the directional error control of augmented step-down procedure proved by Shaffer (1980) and the other on the monotonicity of the critical values of step-up procedure proved by Dalal and Mallows (1992), are revisited and improved in this article. Shaffer’s result on the directional error control property of augmented step-down procedure with...

BACKGROUND The serial transverse enteroplasty (STEP) has been shown to improve nutritional indices in an animal model of short bowel syndrome. The aim of this study was to review short-term surgical and nutritional outcomes in the first cohort of infants to undergo the STEP procedure at our institution. METHODS All patients who underwent the STEP procedure during a 26-month period from Februa...

Augmentation of deficient and atrophic alveolar ridges is an important aspect of dental implant therapy with the goal of providing a functional restoration in harmony with adjacent natural dentition. Bone splitting technique is considered a distinguished augmentation method for treatment of deficient alveolar ridges. According to this procedure, the compromised alveolar ridge is opened from the...

We disclose a general two-step procedure to access hitherto unknown and under explored 5- 6-alkynyl-3-fluoro-2-pyridinamidoximes from 6-bromo-3-fluoro-2-cyanopyridines wide range of easily available bench-stable terminal alkynes, using Sonogashira cross-coupling, as the first step. The generation polar amidoxime group is realized at late stage upon treatment alkynylfluorocyanopyridine by hydrox...

A three-step procedure has been developed for the separation of complex mixtures of sterol intermediates in cholesterol biosynthesis. The method has been applied to the separation of sterol intermediates formed from [14C]mevalonate by normal rat hepatocyte culture cells. In Step 1, a short gravity-flow silicic acid column (1.2 x 6.5 cm) separates the incubation products into four classes consis...
