The aim of this work was to study the pharmacokinetics of piperaquine in healthy volunteers. Healthy volunteers received piperaquine and tablets of Artekin by oral administration. The plasma samples were analyzed for piperaquine by liquid-liquid extraction and determined by HPLC-UV. The results demonstrated that the plasma drug concentration-time curves of single and multiple dose of piperaquin...

We present a derivation of the Bekenstein-Hawking entropy from conformal field theories. In particular we consider a six-dimensional string configuration with background metric AdS3 × S3 near the horizon. In addition we introduce momentum modes along the string, corresponding to a BanadosTeitelboim-Zanelli (BTZ) black hole in the anti-de Sitter (AdS) space-time, and a Taub-NUT soliton in the tr...

The twelve-connected metal-organic frameworks {[Ni(3)(OH)(L)(3)].n(solv)}(infinity) and {[Fe(3)(O)(L)(3)].n(solv)}(infinity) [LH(2) = pyridine-3,5-bis(phenyl-4-carboxylic acid)] have been prepared and characterised: these materials can be desolvated to form porous materials that show adsorption of H(2) up to 4.15 wt% at 77 K.

Abstract In this paper, we study the semiclassical behavior of distorted plane waves, on manifolds that are Euclidean near infinity or hyperbolic infinity, and non-positive curvature. Assuming there is a strip without resonances below real axis, show waves bounded in $L^2_{loc}$ independently $h$ they admit unique measure prove bounds their $L^p_{loc}$ norms.

For $0\leq H< 1/2$, we construct entire $H$-graphs in $\mathbb{H}^2\times\mathbb{R}$ that are parabolic and not invariant by one parameter groups of isometries $\mathbb{H}^2\times\mathbb{R}$. Their asymptotic boundaries $(\partial_\infty\mathbb{H}^2)\times\mathbb{R}$; they dense at infinity. When $H=0$ the examples minimal graphs constructed P. Collin second author [2].

The isothermal structural relaxation of glassy, spin-cast polymer thin films has been investigated. Specifically, the thickness h of freshly cast poly(methyl methacrylate) thin films was measured over time using spectroscopic ellipsometry. The spin-cast films exhibit a gradual decrease in thickness, which is attributed to structural relaxation of the glass combined with simultaneous solvent los...

Two new copper metal-organic frameworks containing 5-nitro-1,3-benzenedicarboxylate (5-nbdc) have been prepared from the reaction between Cu(NO(3))(2).3H(2)O and H(2)(5-nbdc) in DMF at different temperatures. Single crystal X-ray structures of {[Cu(2)(5-nbdc)(2)(DMF)(2)].2DMF}(infinity) () and {[Cu(2)(5-nbdc)(2)(DMF)(2)].3(1/3)DMF}(infinity) () revealed similar sheet structures, containing tria...

Isolated giant axons were voltage-clamped in seawater solutions having constant sodium concentrations of 230 mM and variable potassium concentrations of from zero to 210 mM. The inactivation of the initial transient membrane current normally carried by Na(+) was studied by measuring the Hodgkin-Huxley h parameter as a function of time. It was found that h reaches a steady-state value within 30 ...

Suppose V is a potential decaying near infinity. Let us denote by NJ V) the number of eigenvalues of H = -A + V below -E. The finiteness (resp. infiniteness) of N,,(V) is determined by the rate of decay of V at infinity (see Reed-Simon [4, X111.31) In fact, N,(V) < co if V(x) B -c/~xI*+~, while N,(V) = cc for V(x) < -c/\x~*~‘. For the borderline case V(x)c/lx12 one even has that N,,(V) < CO (re...
