Abstract When using solid fuels for live fire training, NFPA 1403: Standard on Live Fire Training Evolutions requires that the materials be wood based. While standard offers guidance type of are permissible use in it little way quantitative methods selecting an appropriately sized fuel package. In order to examine effects mass and orientation heat release behavior, free burn rate (HRR) experime...
Sodium salicylate containing microemulsions have been formulated, based on the previous phase diagram studies, using a pharmaceutically acceptable surfactant and oil. The effects of formulation variables on the release profile of the drug from microemulsion through intact rat skin were also determined experimentally. In this investigation, two commercially available lecithins (namely Epikuron 2...
Background and Purpose: Oral administrations have been used for many years as a main method comparing to other methods. Sustained release techniques have been a great interest recently. Matrix polymers are one of the ways used to prepare a sustained-release drug and are most widely used to prepare the controlled-release drugs. Cellulose derivatives are the most common ones. Solubilities of so...
hard gelatin capsule filled with acetaminophen, osmotic agent (sorbitol), a release promoter (sodium dodecyl sulfate), coated with a semipermeable cellulose acetate membrane containing a hydrophobic plasticizer (castor oil) and sealed with white bees wax plug was designed. when placed in the sink water penetrates the membrane, dissolves the osmotic agent and increases the osmotic pressure insid...
in this study, microspheres containing estradiol valerate were prepared by solvent evaporation method using poly (glycolide-co-lactide) (plga 50:50) and poly (lactide). the effect of different process variables such as polymer type, drugpolymer ratio, stirring rate, volume of internal phase and temperature of external phase on the morphology, particle size distribution, encapsulation efficiency...
pegylated polypropyleneimine (ppi) dendritic scaffold was used for the delivery of an anti-leukemic drug, imatinib. the current study evolves and emerges the use pegylated ppi dendritic scaffold for the delivery of this drug. in this imatinib was synthesized and loaded with pegylated ppi dendritic scaffold. parameters such as ft-ir, nmr, sem, drug release, dsc and hemolytictoxicity are required...
background: the development of injectable sustained-release products are of great interest to veterinary pharmaceuticals and animal health business. recently, great attention has been paid to in situ gel-forming chitosan/beta-glycerophosphate (chitosan/β-gp) solutions due to their good biodegradability and thermosensitivity. objectives: the general aim of this study was to prepare a novel in si...
