Thermobarometric and Os isotopic data for peridotite xenoliths from late Miocene and younger lavas in the Sierra Nevada reveal that the lithospheric mantle is vertically stratified: the shallowest portions (<45 to 60 kilometers) are cold (670 degrees to 740 degrees C) and show evidence for heating and yield Proterozoic Os model ages, whereas the deeper portions (45 to 100 kilometers) yield Phan...

Abstract: The paper deals with an important textile engineering process: the textile sliver drafting process. It is shown that this process can be modelled as a non-linear time delay system with distributed delays. To convert it into a form more suitable for control purposes, this model is linearized and distributed delays are converted into equivalent lumped delay system. An easy to apply meth...

due to some important applications of guanine electrode in scientific and technology research such as electro-chemical dna based biosensors, and a problem of high redox potential of guanine (0.81 v), our research study concentrates on reducing guanine redox potential by substituting cu, ag, au, ch3, c2h5 and cl on sites of 1, 2 and 9 of guanine. a 5.0% reduction of redox potential for 9-ag-guan...

We use the density matrix renormalization group method to study a one-dimensional chain with Peierls electron-phonon coupling, which describes modulation of electron hopping by lattice distortions. demonstrate that this system is stable against phase separation in dilute limit. only find numerically for large couplings linear approximation coupling becomes invalid; behavior can be stabilized na...

Wearable electronics used in smart clothing for healthcare monitoring or personalized identification is a new and fast-growing research topic. The challenge is that the electronics has to be simultaneously highly stretchable, mechanically robust and water-washable, which is unreachable for traditional electronics or previously reported stretchable electronics. Herein we report the wearable elec...

Density functional theory (DFT) has been applied to model the structure of (Ag•CH2OH/A) complexes previously experimentally characterized by electron paramagnetic resonance (EPR) in zeolite matrices. The magnetic parameters of (Ag•CH2OH/A) were found to depend on the local structure of the zeolite represented by clusters referred to as 3T and 6T, and also on the applied computational method. A ...

In this study, effect of sliver-doping on the crystal structure, the nanofibrous morphology and the photocatalytic activity of titanium oxide nanofibers have been investigated. Silver-doped TiO2 nanofibers having different silver contents were prepared by calcination of electrospun nanofiber mats consisting of silver nitrate, titanium isopropoxide and poly(vinyl acetate) at 600 C. The results a...
