evaluation of the geochemistry and hydrochemical quality of bam salt dome located in southern iran, was conducted in this study. two composite samples from salt units were collected and analysed by xrd and xrf to determine their mineral and elemental compositions. water samples were also collected from the only spring in the area and analysed for major anions, cations and some toxic elements. t...

BACKGROUND AND PURPOSE Our goal was to characterize the geometry of simple-lobed cerebral aneurysms and to find the absolute size of these lesions from angiographic tracings. METHODS Measurements of angiographic neck width (N), dome height (H), dome diameter (D), and semi-axis height (S) were obtained from tracings of 87 simple-lobed lesions located at the basilar bifurcation (BB), middle cer...

BACKGROUND AND PURPOSE The ability to discriminate between ruptured and unruptured cerebral aneurysms on a morphological basis may be useful in clinical risk stratification. The objective was to evaluate the importance of inflow-angle (IA), the angle separating parent vessel and aneurysm dome main axes. METHODS IA, maximal dimension, height-width ratio, and dome-neck aspect ratio were evaluat...

Conventional images of tourist sites are trimmed off the unnecessary scenery from the whole scenery in the fixed viewing angle of the cinematographer’s intention. Therefore, when people visit a tourist destination, they are often disappointed about the gap between video image and actual sight. In order to eliminate this gap, we developed the Digital Dome Theatre System in 2009. It can project u...

We have studied the receptors for phorbol ester tumor promoters in a set of cultures of mammary cell lines derived from the same dimethylbenz(a)anthracene-induced tumor. These lines differ in cell morphology and in the ability to form domes either spontaneously or under the action of inducers. Tumor promoters inhibit dome formation. We asked whether receptors for tumor promoters could also medi...

The lung-expanding action of the diaphragm is primarily related to the descent of the dome produced by the shortening of the muscle fibers. However, when the phrenic nerves in dogs are selectively stimulated at functional residual capacity, the muscle insertions into the lower ribs also move caudally. This rib motion should enhance the descent of the dome and increase the fall in pleural pressu...

Metallic spherical dome shells have received much attention in recent years because they have proven to possess highly impressive optical properties. The expected distinctive changes occurring owing to quantum confinement of conduction electrons in these nanoparticles as their thickness is reduced, have not been properly investigated. Here we carry out a detailed analytical derivation of the qu...

An emerging elementary particle imaging technique called muography has increasingly been used to resolve the internal structures of volcanoes with a spatial resolution of less than 100 m. However, land-based muography requires several days at least to acquire satisfactory image contrast and thus, it has not been a practical tool to diagnose the erupting volcano in a real time manner. To address...

This report describes the composition and some properties of the cast iron and wrought iron that form the dome of the U.S. Capitol. It is a compilation of two recent investigations, one by NIST and one by Lucius Pitkin, Inc. These investigations were implemented by the Office of the Architect of the Capitol to determine the dome’s condition and also to predict how the outer shell might respond ...

The atmospheric conditions above Dome A, a currently unmanned location at the highest point on the Antarctic plateau, are uniquely suited to astronomy. For certain types of astronomy Dome A is likely to be the best location on the planet, and this has motivated the development of the Plateau Observatory (PLATO). PLATO was deployed to Dome A in early 2008. It houses a suite of purpose-built site...
