Abstract
The concept of causality٫continually٫from the seventeenth century٫ As yet has been debated between philosopfers and partly physicists. This diversity of opinions rely on their’s ontologic and epistemologic positions. In the article, is attempted to compare causality in the philosophy of contem -porary(west) and Quantum physics with Islamic Philosophy (according to motahhary) In first chapter, universal hypothesizes and reasons of requirement to analyze causality is expressed. In second chapter,we turn to views of four famous hilosophers in the seventeenth and eiyhteenth century: locke ,Berkeley, Hume, kant. In third chapter, we attend to some current approach the recent philosophers...

Abstract
Philosophy of Chemistry: The missed piece of Philosophy of Science’s tower. This thesis is intended to bring in this recently emerged branch of Philosophy of science. In section 1, some trends of Philosophizing in chemistry by some scientist and philosopher have been investigated. Why Philosophy of Chemistry had been turned off until recently? Section 2 deals with this question. In section 3 some problems in Philosophy of Chemistry have been introduced
Pre-reduction of Manganese Ore by Natural Gas for Ferromanganese Production
, Ph.D. Dissertation Sharif University of Technology ; Yoozbashizadeh, Hossein (Supervisor) ; Safarian, Jafar (Co-Supervisor)
Abstract
Pre-reduction of some manganese sources (low-grade Venrach and Godar-Sabz ores, high-grade Comilog ore, pellet, pure oxide) by methane gas has been investigated in this research. HSC-Chemistry and FactSage software were used for thermodynamic study of the process. Thermodynamic results indicated that methane may progress to manganese carbide formation, and the reduction process can run autonomously involving less carbon dioxide emission comparing to common ferromanganese process. Several techniques including XRF, XRD, in-situ XRD, SEM-EDS, and thermogravimetry were used in sample characterization and experiments. In addition to the thermal decomposition reactions which were affected by...
