Multi-characterization of electron-induced defects in highly oriented pyrolytic graphite
(2016)
Engineering the properties of materials through defects is at the forefront of research in Materials Science. Here, we investigate the defects produced on highly oriented pyrolytic graphite (HOPG) samples irradiated with ...
Enhancement of dissolution rate of furosemide using a solid dispersion with D-glucosamine HCl
(2016)
Furosemide is a potent high ceiling (loop) diuretic mainly used in the treatment of edematous states associated with cardiac, renal, and hepatic failure, and the treatment of hypertension. Furosemide has been classified ...
Dynamic heterogeneity in the monoclinic phase of CCl4
(2016)
Carbon tetrachloride (CCl4) is one of the simplest compounds having a translationally stable monoclinic phase while exhibiting a rich rotational dynamics below 226 K. Recent nuclear quadrupolar resonance (NQR) experiments ...
Critical exponents and scaling invariance in the absence of a critical point
(2016)
The paramagnetic-to-ferromagnetic phase transition is classified as a critical phenomenon due to the power-law behaviour shown by thermodynamic observables when the Curie point is approached. Here we report the observation ...
Interpolation of geometric structures compatible with a pseudo Riemannian metric
(2016)
Let (M, g) be a pseudo Riemannian manifold. We consider four geometric structures on M compatible with g: two almost complex and two almost product structures satisfying additionally certain integrability conditions. For ...
Analytical and rheological studies of modified gel dosimeters exposed to X-ray beams
(2016)
The need to know the dose of X-rays to be applied to patients suffering diseases such as cancer requires accurate and stable dosimetric devices. Currently, the use of gelatin-based dosimeters has yielded excellent results ...
Lie subalgebras of the matrix quantum pseudodifferential operators
(2016)
We give a complete description of the anti-involutions that preserve the principal gradation of the algebra of matrix quantum pseudodifferential operators and we describe the Lie subalgebras of their minus fixed points.
Maximal totally geodesic submanifolds and index of symmetric spaces
(2016)
Let M be an irreducible Riemannian symmetric space. The index i(M ) of M is the minimal codimension of a totally geodesic submanifold of M. In [1] we proved that i(M ) is bounded from below by the rank rk(M) of M, that is, ...
Matrix Gegenbauer polynomials : the 2×2 fundamental cases
(2016)
In this paper, we exhibit explicitly a sequence of 2 × 2 matrix valued orthogonal polynomials
with respect to a weight W p,n , for any pair of real numbers p and n such that 0 < p < n. The entries of these polynomiales ...
Center of mass and spin for isolated sources of gravitational radiation
(2016)
We define the center of mass and spin of an isolated system in general relativity. The resulting relationships between these variables and the total linear and angular momentum of the gravitational system are remarkably ...
