Pilgrim Hot Springs has a known shallow geothermal reservoir with temperatures approaching 91 ̊C in the top 100 meters of the system that underlies the main hot springs area of 1.5 km. The deeper reservoir is less understood with similar temperatures at the basement surface 320 meters directly beneath the hot springs. The aspect of this research is to create a stratigraphic model and delineate p...

The equations of planar motion of a mass attached to two anchored massless springs form a symmetric Hamiltonian system. The system has a single dimensionless parameter L, corresponding to the spacing between the anchors. For L > 1, there is a stable equilibrium at which the springs are in tension and lie on a line, but for L < 1, this equilibrium has both springs in compression, and is unstable...

Bonding-pad densities on high-performance integratedcircuit chips are beginning to exceed the limits of available interconnect technologies. Also, stresses due to thermal mismatch in flip-chipped packages are reducing time to contact failure. We have addressed both of these problems by microlithographically fabricating highly elastic cantilever springs in linear arrays on pitches down to 6 μm. ...

This study was performed to characterize hydrochemical properties of springs based on their geological origins in Taiwan. Stepwise discriminant analysis (DA) was used to establish a linear classification model of springs using hydrochemical parameters. Two hydrochemical datasets-ion concentrations and relative proportions of equivalents per liter of major ions-were included to perform predictio...

What is the diversity of cyanobacteria in iron-depositing hot springs? We are currently conducting preliminary studies on the diversity of iron-tolerant CB isolated from irondepositing hot springs in and around Yellowstone National Park (WY, USA). Molecular analysis has confirmed the prediction [1] that the diversity of iron-tolerant CB is ill-defined. Analysis of 16S rRNA sequences from 15 uni...

in this study, water samples were collected from 10 thermal and non-thermal springs of mahalat setting during four periods in 2011. the discharge rates of these springs vary from 2 l/s to 45 l/s and their temperature range from an average minimum of 18oc to maximum 47oc. spring water is high in so4-cl and this is related to gypsum dissolution. correlation coefficient, principal component analys...
