Ibuprofen solid dispersions were prepared by the solvent and fusion-solvent methods using polyethylene glycol (PEG), polyvinylpyrrolidone (PVP), eudragit RS PO, eudragit RL PO and hydroxypropylmethylcellulose (HPMC) as carriers to improve physicochemical characteristics of ibuprofen. The prepared solid dispersions were evaluated for the flowability, solubility characteristics and dissoluti...
This study investigates various models to represent the gross geometric shape of the Moon. Asymmetric polyaxial geometric modelsnamely three-, fourand six-axial lunar figure are compared and contrasted with the axially symmetric three-axis ellipsoidal model derived from Chang'e 1 and SELENE laser altimetry data. All solutions confirm a hydrostatically stable lunar shape shifted with respect to ...
For searching both high-performances and better fits for near-room temperature thermoelectric materials, we here carried out a theoretical study on properties doping regulation of Mg3X2 (X = As, Sb, Bi) by the combined method first principle calculations semi-classical Boltzmann theory. The n-type Mg3As2, Mg3Sb2, Mg3Bi2 were studied, it was found that dimensionless figures merit, zT, are 2.58, ...
The presence of Damghan Erg in West of Damghan Playa indicates high wind activity in this desert region. Due to technological advances and population growth in recent decades, large parts of past land uses have changed. These changes can exacerbate wind erosion and affect lands sedimentation. In this study, first, the land use maps of years 1974 and 2003 were prepared. The comparison of these m...
