Preparation of micron and nano sized ammonium perchlorate (AP) particles in propellant formulation is required for access high burning rate propellants. The decomposition and burning rate of AP particles are mainly affected by decreasing the particle size, which can decrease the decomposition temperature, and increase burning rate.  AP particles at the micro and nano-scales, have a great influe...

PBXN-111 is a cast cured underwater explosive containing RDX, ammonium perchlorate, aluminium powder and HTPB binder. In this research, the kinetics and thermodynamic properties of thermal decomposition of this PBX investigated by Kissinger and Flynn-Wall-Ozawa (FWO) methods based on differential scanning calorimetry under non-isothermal condition with heating rate of 5, 10, 15 and 20 °C/mi...

The phenomenon of fiscal illusion has always been an intriguing topic in the public finance literature. Fiscal illusion is a concept in which misinterpretation of fiscal parameters and tax expenses and liabilities lead to bias in budgetary decision making at all levels of the government. The current research presents an empirical analysis of the fiscal illusion in the Iranian economy, using fiv...

Abstract Background and Objective: Perchloroethylene (PCE) is a chlorinated hydrocarbon used as a solvent in many industrial processes. In contaminated water and soil a great deal of PCE is found. This study aimed to determine the rate of decomposition of PCE occurred after advanced oxidation. Material and Methods: In this descriptive-analytic study conducted (2011) in public health faculty...
