Importance of colloidal dispersion in pharmacy Pharmaceutical Applications of colloids: Colloids are extensively used for modifying the properties of pharmaceutical agents. The most common property that is affected is the solubility of a drug .However‚ colloidal forms of many drugs exhibits substantially different properties when compared with traditional forms of these drugs. Certain medicinals have been found to possess unusual or increased therapeutic properties when formulated in the colloidal

with two different cubic and hexagonal structures. The value of TN was reported to be 350 K by Chamberland et al [ ] corresponding to anti ferromagnetic ordering. However‚ Battle et al [ ] concluded TN to be 278 ± 5 K from Massbauer and neutron diffraction studies on 57Fe doped SrMnO3 which value of TN was expected to be little different from that for undoped one. The variation of electrical conductivity with oxygen stoichiometry and the correlation of high temperature stability with structure were

Physics (from Greek φυσική (ἐπιστήμη)‚ i.e. "knowledge of nature"‚ from φύσις‚ physis‚ i.e. "nature"[1][2][3][4][5]) is the natural science that involves the study of matter[6] and its motion through space and time‚ along with related concepts such as energy and force.[7] More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves.[8][9][10] Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy

`Jump to: navigation‚ search A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material. The size distribution is often of critical importance to the way the material performs in use. A sieve analysis can be performed on any type of non-organic or organic granular materials including sands‚ crushed rock‚ clays‚ granite‚ feldspars‚ coal‚ soil‚ a wide range of manufactured
