Brane world cosmologies seem to provide an alternative explanation for the present accelerated stage of the Universe with no need to invoke either a cosmological constant or an exotic quintessence component. In this paper we investigate statistical properties of gravitational lenses for some particular scenarios based on this large scale modification of gravity. We show that a large class of su...

Optimal condition-based microemulsion is key to achieving great efficiency in oil removal. One useful empirical equation predict an optimal condition a hydrophilic–lipophilic deviation (HLD). However, the K constants of each surfactant should be same combine HLD equations for mixed surfactant. Recently, normalized hydrophilic-lipophilic (HLDN) was presented avoid this limitation. This work soug...

Purpose: Enalapril maleate (EPM), was used for hypertension and congestive heart failure. In this way, an innovative delivery system with mPEG–PCL was synthesized and the release profile of the EPM from the drug-loaded polymersomes was evaluated. Methods: Di-block methoxy)-poly (ethylene glycol) - Poly (caprolactone) (mPEG-PCL) copolymers were synthesized and used to prepare of polymersom...

The interaction of drugs and polymers used to incorporate in or surface modify/coat the liposomes can affect the phase transition, fluidity and other physical properties as well as in vivo fate of vesicles. In this study, differential scanning calorimetry (DSC) was used to investigate changes in the temperature and the enthalpy of phase transition of liposomes of various electrical charges foll...

The nuclear lamina provides an architectural framework for the nuclear envelope and an attachment site for interphase chromatin. In Drosophila eggs and early embryos its major constituent, lamin Dm0, interacts with a lamina protein called YA. When the lamin-interaction region of YA is deleted, YA still enters nuclei but fails to localize to nuclear envelopes, suggesting that lamin interaction t...

A model has been proposed to describe the potential barrier that appears during interaction of two compacted layers consisting hydrophilic oxide nanoparticles different sizes in each layer upon saturation this structure with adsorbed water. The dependence space charge density powder material on particles it theoretically calculated. distribution over thickness contact between obtained.

Multiple layers of polyvinyl alcohol (PVA) coating are generated onto silica gel by thermal immobilization to form a stationary phase applied for hydrophilic interaction liquid chromatography (HILIC). It offers an easy way to manipulate the thickness of PVA coating and the obtained stationary phase demonstrated high efficiency and high chemical stability.
