Spin-gap and antiferromagnetic correlations in low-dimensional PbNi2-xAxV2O8 compounds (A = Mg, Co)
(2002)
The effect of the impurity doping in the quantum-spin chains of the PbNi2V2O8 Haldane-gap compound is studied. We report elastic neutron scattering and bulk magnetic susceptibility measurements on the quasi-one-dimensional ...
Minimum relative entropy criterion for damage detection and location
(Affiliation: Brunel University, School of Engineering and Design, United KingdomAffiliation: University of Cyprus, Department of Mechanical and Manufacturing Engineering, CyprusCorrespondence Address: Mares, C.Brunel University, School of Engineering and DesignUnited Kingdomemail: Cristinel.Mares@brunel.ac.uk, 2009)
Relative entropy has been employed, as an alternative to other regularization methods, in solving ill-conditioned linear inverse problems. Damage detection when treated as structural modification imparted by the damage ...
Second-harmonic generation in a sound beam reflected and transmitted at a curved interface
(2000)
This article presents a model for second-harmonic generation in a sound beam that is reflected from or transmitted through a curved interface. Propagation in homogeneous fluids is assumed. Simple analytic solutions are ...
Manganese citrate chemistry: Syntheses, spectroscopic studies, and structural characterizations of novel mononuclear, water-soluble manganese citrate complexes
(2000)
The first two mononuclear manganese citrate complexes, (NH4)4[Mn(II)(C6H5O7)2] (1) and (NH4)5[Mn(III)(C6H4O7)2]·2H2O (2) were synthesized in aqueous solutions near physiological pH values. They were isolated in their pure ...
Synthesis, spectroscopic, and structural characterization of the first aqueous cobalt(II)-citrate complex: toward a potentially bioavailable form of cobalt in biologically relevant fluids
(2000)
Citric acid represents a class of carboxylic acids present in biological fluids and playing key roles in biochemical processes in bacteria and humans. Its ability to promote diverse coordination chemistries in aqueous ...

Chorioamnion, the membrane surrounding a fetus during gestation (the "amniotic sac"), is a structural soft tissue for which the mechanical behavior is poorly understood-despite its critical role in maintaining a successful ...
Yield behavior of commercial Al-Si alloys in the semisolid state
(2004)
Systematic experimental work and modeling efforts have been conducted to characterize the yield behavior of commercial aluminum alloys in the semisolid state. In this study, extensive compression experiments were performed ...
Comparison of free surface polarization of NiMnSb and Co2 MnSi
(2006)
We present a systematic study of the polarization of the transport current from a variety of NiMnSb and Co2 MnSi thin films and bulk material using point contact Andreev reflection spectroscopy. The simple analysis suggests ...
Thermoelectric properties of LaNi1-xCoxO3 solid solution
(2003)
The thermoelectric properties of the selected members of the LaNi 1-xCoxO3 solid solution were investigated. The electrical properties of the solution investigated were determined from the doping level. The substitution ...
