Temperature dependence of the pressure induced monoclinic distortion in the spin S=1/2 Shastry–Sutherland compound SrCu2(BO3)2
(
Elsevier Ltd
, 2014 , Article)
We investigate the monoclinic distortion that occurs at 4.7 GPa at room temperature in the frustrated Shastry-Sutherland model quantum magnet SrCu 2(BO3)2 as a function of pressure and temperature by means of powder and ...
Output feedback sliding mode control for a linear multi-compartment lung mechanics system
(
Taylor and Francis Ltd.
, 2014 , Article)
In this paper, we develop a sliding mode control architecture to control lung volume and minute ventilation in the presence of modelling system uncertainties. Since the applied input pressure to the lungs is, in general, ...
Correlated decay of triplet excitations in the shastry-sutherland compound SrCu2 (BO3)2
(
American Physical Society
, 2014 , Article)
The temperature dependence of the gapped triplet excitations (triplons) in the 2D Shastry-Sutherland quantum magnet SrCu2(BO3)2 is studied by means of inelastic neutron scattering. The excitation amplitude rapidly decreases ...
Mishandling and exposure of farm workers in Qatar to organophosphate pesticides
(
Elsevier Inc.
, 2014 , Article)
We used a combination of subjective (questionnaire) and objective (urinary metabolites) measurements to evaluate factors that can predict the exposure of farm workers in Qatar to organophosphate pesticides and to assess ...
Theoretical study on the solvation of C60 fullerene by ionic liquids
(
American Chemical Society
, 2014 , Article)
The solvation of C60 fullerene by 24 different ionic liquids belonging to the imidazolium, piperazinium, and cholinium families was analyzed from a nanoscopic viewpoint using classic molecular dynamics simulations and ...
An experimental investigation into crushing behavior of radially stiffened GFRP composite tubes
(
Elsevier Ltd
, 2014 , Article)
State-of-the-art studies of the crushing of composite tubes reveal different factors affecting their crashworthiness. Of those factors, the geometrical property of the tube is of great interest. In the current study, four ...
Salt water corrosion resistance of electrodeposited Ni-layered silicate nanocomposite coatings from Watts' type solution
(
Elsevier B.V.
, 2014 , Article)
Pure nickel and nickel-montmorillonite (Ni-MMT) composite coatings were produced using pulse current electrodeposition from Watts' type solution. Experimental results show that the codeposition of MMT particles into the ...
Benthic marine algae of the arabian gulf: A critical review and analysis of distribution and diversity patterns
(
Schweizerbart Science Publishers
, 2014 , Article)
The Arabian Gulf is an extremely inhospitable and physiologically-stressful environment for marine organisms since they are exposed to the widest range and the highest sea temperatures in the world, as well as high salinities. ...
Rough oscillatory singular integrals on ℝⁿ
(
Instytut Matematyczny
, 2014 , Article)
We establish sharp bounds for oscillatory singular integrals with an arbitrary real polynomial phase P. The kernels are allowed to be rough both on the unit sphere and in the radial direction. We show that the bounds grow ...
Self-standing elastomeric composites based on lithium ferrites and their dielectric behavior
(
American Institute of Physics Inc.
, 2014 , Article)
Lithium ferrite (LiFe5O8) is an attractive material for technological applications due to its physical properties, which are significantly dependent on the preparation method and raw materials. In this work, LiFe5O8 ...
