چکیده
The exact results for thermodynamical properties of one-dimensional spin-1 2 isotropic XY model with Dzyaloshinskii-Mo-riya interaction in random lorentzian transverse field are obtained. This permits to discuss some approximate methods of disordered spin systems theory. The approximate scheme of examining the thermodynamics of one-dimensional spin-1 2 XXZ Heisenberg model with Dzyaloshinskii-Moriya interaction in random lorentzian field is suggested.

Reactions between tunichrome Mm-1, a tunicate blood pigment, and vanadium ions in acidic and neutral media.
Tunichromes are yellow, polyphenolic tripeptides prevalent in blood cells of tunicates (suborders phlebobranchia and stolidobranchia). Spectrophotometric studies of reactions between tunichrome Mm-1 and VV or VIV ions were conducted in vitro in various media to crudely approximate cellular conditions: deionized water, aqueous methanol, and aqueous buffers at pH 2 and 7. Catechol was used in par...
متن کاملUsing Model Test Data to Assess Viv Factor of Safety for Scr and Ttr in Gom
This paper presents results obtained as part of the DeepStar Phase 10 program on VIV Factors of Safety. The objective was to develop a general methodology to calibrate Factors of Safety for VIV-induced fatigue and to apply it to partially straked risers. This was achieved using reliability methods, accepted industry VIV prediction software and state-of-the-art model test experiments. Most oil c...
متن کاملProny-based Method for Time-frequency Analysis of Marine Riser VIV Data
Vortex induced vibrations (VIV) of long flexible risers subjected to ocean currents exhibit a strongly nonlinear phenomenon. Although significant efforts have been done for the frequency or time-frequency analysis of this complicated phenomenon, an effective method is still lacking. The objective of this paper is to provide a new method — a Prony-based method — for analyzing the time-varying fr...
متن کاملA Novel Piezoelectric Energy Harvester Using the Macro Fiber Composite Cantilever with a Bicylinder in Water
A novel piezoelectric energy harvester equipped with two piezoelectric beams and two cylinders was proposed in this work. The energy harvester can convert the kinetic energy of water into electrical energy by means of vortex-induced vibration (VIV) and wake-induced vibration (WIV). The effects of load resistance, water velocity and cylinder diameter on the performance of the harvester were inve...
متن کاملReactions between vanadium ions and biogenic reductants of tunicates: spectroscopic probing for complexation and redox products in vitro.
Several species of marine tunicates store oxygen-sensitive VIII in blood cells. A sensitive colorimetric VIII assay was used to survey the leading candidates for the native reducing agent of vanadate in tunicates (i.e., An-type tunichromes, glutathione, NADPH, and H2S) in reactions with VV or VIV ions under anaerobic, aqueous conditions at acidic or neutral pH. Except for the case of An-1 and V...
