The characteristics of confinement properties and magnetohydrodynamics (MHD) stabilities of the super dense core (SDC) plasmas are intensively studied in the Large Helical Device (LHD) experiment. The SDC plasmas are produced in the configuration with outward shifted magnetic axis and rapid fueling into the core region by pellet injection. The SDC plasmas have high electron pressure due to the ...

Collapse of the rotating magnetized molecular cloud core is studied with the axisymmetric magnetohydrodynamical (MHD) simulations. Due to the change of the equation of state of the interstellar gas, the molecular cloud cores experience several different phases as collapse proceeds. In the isothermal run-away collapse (n ∼< 10 H2 cm ), a pseudo-disk is formed and it continues to contract till th...

This study describes a facile two-step approach to modify the surface of nanoparticles, thereby imparting a core-shell structure to the system. The core consists of magnetic nanoparticles and the shell is composed of thermoresponsive hydroxypropyl cellulose, using a coupling agent to covalently bind the core to the shell. Hydroxypropyl cellulose is known for its biocompatibility and biodegradab...

A simple and efficient method for the chemoselective 1,1-diacetate protection of aromatic aldehydes with acetic anhydride by using Ni2+ supported on hydroxyapatite-core-shell magnetic γ-Fe2O3 nanoparticles (γ-Fe2O3@HAp-Ni2+) under solvent free conditions. This method has several advantages, including high yield, short reaction time, simple work-up and recyclable property of the catalyst. The ca...

The algorithm takes as only input a llst of words, preferably but not necessarily in phonemic transcription, in any two putatively related languages, and sorts it into decreasing order of probable cognatlon. The processing of a 250-1tem bilingual list takes about five seconds of CPU time on a DEC KLI091, and requires 56 pages of core memory. The algorithm is given no information whatsoever abou...

An evolutionary core memory system is proposed which simulates reactions between biological molecules in membrane bound compartments in a solvent. In the imitation of biological substances, every word in the core is classi ed as a Membrane, Nutrition, DNA, or Protein; and the actions of the core proceed by metabolic reactions catalyzed by Proteins. The core is partitioned into small sections by...

S U M M A R Y The secular variation of the geomagnetic field is due to flow of molten iron in the Earth’s core. One can invert for the flow at the core-surface, assuming that the magnetic field is frozen into the core fluid. The validity of the frozen flux approximation (FFA) depends on the scale length of the magnetic field and the period of core motions. A first-order quantitative assessment ...
