The conventional K-Ar dating method was applied to the 1986 dacite flow from the new lava dome at Mount St. Helens, Washington. Porphyritic dacite which solidified on the surface of the lava dome in 1986 gives a whole rock K-Ar “age” of 0.35±0.05 million years (Ma). Mineral concentrates from the dacite which formed ins 1986 give K-Ar “ages” from 0.34±0.06 Ma (feldspar-glass concentrate) to 2.8±...
We present an optofluidic sensor based on an elastomeric two-dimensional (2D) grating integrated inside a hemispherical fluid chamber. A laser beam is diffracted before (reflection) and after (transmission) going through the grating and liquid in the dome chamber. The sensing mechanism is investigated and simulated with a finite-difference time-domain-based electromagnetic method. For the exper...
Tissue engineering is currently exploring new and exciting avenues for the repair of soft tissue and organ defects. Adipose tissue engineering using the tissue engineering chamber (TEC) model has yielded promising results in animals; however, to date, there have been no reports on the use of this device in humans. Five female post mastectomy patients ranging from 35 to 49years old were recruite...
BACKGROUND/AIMS It has been shown that MDCK cells, a cell line derived from canine renal tubules, develop cell domes due to fluid pumped under cell monolayer and focal detachment from the adhesion surface. In vitro studies have shown that primary cilia of kidney tubular epithelial cells act as mechanosensors, increasing intracellular calcium within seconds upon changes in fluid shear stress (SS...
The most important characteristic of dome and factors influencing it in the Islamic Iranian architecture that is different from other courses is construction and construction methods of them. Over time, different factors are involved in the process of formation of the domes. It is one of the factors influencing the structure of Iranian-Islamic domes. By examining the structure of Iranian-Islami...

Due to the dryness of the weather in most parts of Iran and the lack of sufficient rainfall in more than six months of the year in most places, resulting in the seasonality of rivers and the lack of access to water, various arrangements for fresh water supply in the dry seasons has been established. The construction of the AB ANBAR (water reservoir and cistern) is one of innovative ways to supp...
When volatile solvents are used for paper chromatography, as in the systems described by Bush (1952) for separation of steroids, it is usually necessary to hang the paper in the tank for several hours' equilibration before the addition of the mobile phase. If equilibration is allowed to proceed overnight much of the next day will be taken up with running the chromatogram. An apparatus has there...
in this paper an intelligent method through general regression neural networks (grnn) is presented to estimate the depth of salt domes from gravity data. neural networks are as a good tool for automatic interpretation of geophysical data especially for depth estimation of gravity anomalies. the gravity signal is a nonlinear function of depth and density and the geometrical parameters of the bur...
