objective(s): in the current study, sunscreen and moisturizing properties of solid lipid nanoparticle (sln)-safranal formulations were evaluated. materials and methods:series of sln were prepared using glyceryl monostearate, tween 80 and different amounts of safranal by high shear homogenization, and ultrasound and high-pressure homogenization (hph) methods. sln formulations were characterized ...

A parallel fully coupled one-level Newton-Krylov-Schwarz method is investigated for solving the nonlinear system of algebraic equations arising from the finite difference discretization of inverse elliptic problems. Both L and H least squares formulations are considered with the H regularization. We show numerically that the preconditioned iterative method is optimally scalable with respect to ...

We analyse the dynamics of an open membrane, both for the free case and when it is coupled to a background three-form, whose boundary is attached to p-branes. The role of boundary conditions and constraints in the Nambu-Goto and Polyakov formulations is studied. The low-energy approximation that effectively reduces the membrane to an open string is examined in detail. Noncommutative features of...

We investigate the implications of an episodic versus semantic memory representation in a model of serial task switching. Altmann and Gray (2002; 2004) have developed a model in which the rate of memory activation, decay, and interference are tightly coupled in an explanation of learning, forgetting, and performance. A central assumption of their model is the use of an episodic memory trace for...

background and objectives: phosphorus is one of the low bioavailable macroelements. use of microorganisms in biofertilizers could release phosphorus from insoluble compounds. pseudomonas putida p13 and pantoea agglomerans p5 are well recognized for application as phosphate solubilizing bioinoculants and are used as solid carrier based. liquid bioinoculants are preferred for economizing producti...

In two space-time dimensions, there is a theory of Lorentzian quantum gravity which can be defined by a rigorous, non-perturbative path integral and is inequivalent to the well-known theory of (Euclidean) quantum Liouville gravity. It has a number of appealing features: i) its quantum geometry is non-fractal, ii) it remains consistent when coupled to matter, even beyond the c=1 barrier, iii) it...

We examine magnetic and electric near horizon regions of maximally supersymmetric Dbrane and NS5-brane bound states and find transformations between near horizon regions with worldvolume dual magnetic and electric fluxes. These point to dual formulations of NCYM, NCOS and ODp theories in the limit of weak coupling and large spatial or temporal noncommutativity length scale in terms of weakly co...

In this paper we consider the (2D and 3D) exterior problem for the non homogeneous wave equation, with a Dirichlet boundary condition and non homogeneous initial conditions. First we derive two alternative boundary integral equation formulations to solve the problem. Then we propose a numerical approach for the computation of the extra “volume” integrals generated by the initial data. Finally, ...

Daily use of mouthwash is generally recommended to control dental plaque development and limit further adhesion oral bacteria. To this purpose, Chlorhexidine di-gluconate (CHG)-containing products are still the most used antiseptic in health. The aim study was compare antimicrobial antibiofilm activity three different commercial formulations containing CHG at same concentration (0.2%) on main e...

in this paper, we prove some coupled coincidence point theorems for mappings with the mixedmonotone property and obtain the uniqueness of this coincidence point. then we providing useful examples in nash equilibrium.
