High resolution ( 4") aperture synthesis maps of the CO (1 .... 0), 13CO (1 .... 0), 13CO ( 2 .... 1), and associated continuum emission from the FU Orionis candidate V1331 Cygni reveal a massive, 0.5±0.1510 , circumstellar disk surrounded by a flattened gaseous envelope, 6000X4400 AU in size, mass ;;.0.3210 . These images and lower resolution measurements also trace a bipolar outflow and gaseo...

There are several applications and fundamental research areas which require the detection of VUV light at cryogenic temperatures. For these applications we have developed and successfully tested special designs of gaseous detectors with solid photocathodes able to operate at low temperatures: sealed gaseous detectors with MgF2 windows and windowless detectors. We have experimentally demonstrate...

We show that a many-atom Bose system at zero temperature has, in general, a liquid phase in addition to its well-known gaseous phase. A universal phase diagram is presented that is applicable to all Bose systems with a -C6/r6 type of interaction at large interparticle separations. We show that the predicted phase structure has implications on the stability of a gaseous Bose-Einstein condensate ...

conclusions when gaseous ozone was used alone in root canals, its antifungal effect was not sufficient. however, applying aqueous ozone with ultrasonic technique showed stronger antifungal effects than aqueous ozone with manual technique in root canals. background candida albicans is one of the important microorganism which can be isolated from normal flora in the mouth. the resistance of c. al...

Gaseous fluids may move slowly, as smoke does, or at high speed, such as occurs with explosions. High-speed gas flow is always accompanied by low-speed gas flow, which produces rich visual details in the fluid motion. Realistic visualization involves a complex dynamic flow field with both low and high speed fluid behavior. In computer graphics, algorithms to simulate gaseous fluids address eith...

Gaseous beryllium metaborate, Be(B02)2,has been identified mass spectrometrically in the vapor above the beryllium-boron-oxygen system. A st-jdy of this system by differential thermal analysis» and Knudsen effusion using a vacuum balance and mass spectrometer, showt-i solid DeoBo0, to be the only condensed mixed oxide phase present with a melting point of 1495 ± 5C. The following thermodynamic ...

BACKGROUND AND PURPOSE The aim of this study was to assess the first multifrequency transcranial Doppler system that was specially developed to automatically detect and discriminate between solid and gaseous cerebral microemboli. METHODS The multifrequency transcranial Doppler instrumentation insonates simultaneously with 2.5 and 2.0 MHz. Differentiation between solid and gaseous microemboli ...

background several studies have shown that species of the genus hyptis, have promising antimicrobial and antifungal effects. objectives identify of chemical constituents of essential oil from leaves of hyptis martiusii and evaluate its effect against bacterial strains by direct and gaseous contact. materials and methods essential oil was extracted from leaves of hyptis martiusii benth using hyd...

Surface chemistry is a major factor that determines the wettability of materials, and devising broadly applicable coating strategies afford tunable selective surface properties required for next-generation materials remains challenge. Herein, we report fluorinated metal–organic coatings display water-wetting oil-repelling characteristics, wetting phenomenon different from responsive induced by ...

Purpose – The purpose of this paper is to analytically perform gaseous slip flow and heat transfer analysis within a parallel-plate microchannel partially filled with a centered porous medium under local thermal non-equilibrium (LTNE) condition. Heat transfer of gaseous flow in a porous microchannel is analytically studied. Energy communication at the porous-fluid interface is considered by two...
