Linking current river pollution to historical pesticide use: Insights for territorial management?.

The Science of the total environment

Della Rossa P, Jannoyer M, Mottes C, Plet J, Bazizi A, Arnaud L, Jestin A, Woignier T, Gaude JM, Cattan P.
PMID: 27697339

AIM: To assess lactase gene (LCT)-13910C>T polymorphisms in Brazilian non-alcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) patients in comparison with healthy controls.METHODS: This was a transverse observational clinical study with NAFLD patients who were followed at the...

Mediastinal paraganglioma: specific endoscopic ultrasound features.

Endoscopic ultrasound

Sharma SS, Jhajharia A, Maharshi S, Ram S, Shankar V, Katiar P.
PMID: 24949374
Endosc Ultrasound. 2013 Apr;2(2):105-6. doi: 10.4103/2303-9027.117698.

Endoscopic ultrasound (EUS) features of mediastinal paraganglioma have not been described. In this paper, we report a female patient presented with cough and chest pain without any neuroendocrinal symptoms. Final diagnosis of mediastinal paraganglioma was made on thoracoscopic biopsy...

Surface Charge of Silver Iodide and Several Metal Oxides. Are All Surfaces Nernstian?.

Journal of colloid and interface science

Larson I, Attard P.
PMID: 10860606
J Colloid Interface Sci. 2000 Jul 01;227(1):152-163. doi: 10.1006/jcis.2000.6847.

Charge titration data for silver iodide, titanium dioxide, aluminum oxide, silica dioxide and ferric hydroxide are analyzed using a generic site binding model that has the Nernst equation as a limiting form. Both the hypernetted chain and the nonlinear...

Constraint method for deriving nonequilibrium molecular dynamics equations of motion.

Physical review. E, Statistical, nonlinear, and soft matter physics

Galea TM, Attard P.
PMID: 12443191
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Oct;66(4):041207. doi: 10.1103/PhysRevE.66.041207. Epub 2002 Oct 24.

A procedure for developing non-Hamiltonian equations of motion for constrained systems is given. It is shown that such constraints can be used to mimic common statistical systems, both equilibrium (e.g., constant temperature) and nonequilibrium (e.g., shear flow, heat flow),...

Interaction and deformation of viscoelastic particles: nonadhesive particles.

Physical review. E, Statistical, nonlinear, and soft matter physics

Attard P.
PMID: 11415116
Phys Rev E Stat Nonlin Soft Matter Phys. 2001 Jun;63(6):061604. doi: 10.1103/PhysRevE.63.061604. Epub 2001 May 24.

A viscoelastic theory is formulated for the deformation of particles that interact with finite-ranged surface forces. The theory generalizes the static approach based upon classic continuum elasticity theory to account for time-dependent effects, and goes beyond contact theories such...

Statistical mechanical theory for steady state systems. VII. Nonlinear theory.

The Journal of chemical physics

Attard P.
PMID: 17627356
J Chem Phys. 2007 Jul 07;127(1):014503. doi: 10.1063/1.2745300.

The second entropy theory for nonequilibrium thermodynamics is extended to the nonlinear regime and to systems of mixed parity (even and odd functions of molecular velocities). The steady state phase space probability density is given for systems of mixed...

A further insight into the mechanism of biosorption of metals, by examining chitin epr spectra.

Talanta

Tsezos M, Mattar S.
PMID: 18964071
Talanta. 1986 Mar;33(3):225-32. doi: 10.1016/0039-9140(86)80056-x.

Experimental chitin-uranium-copper EPR spectra have been simulated by computer. The simulation suggests that the chitin-copper-uranium EPR spectra are primarily due to a chitin-copper interaction, with insignificant contribution from other paramagnetic species. The simulation suggests two possible complex configurations, both...
