abstract:the general perception of islamic finance is that it prohibits the practice of paying and receiving interest, but islamicfinance is much broader than interest rate prohibition. islamic financial services can be viewed as a set of financialservices which are diversified based on the needs of society.since in the iranian economy most of the enterprises are micro and/or small, micro finan...

a micro-channel heat exchanger reactor with different micro-baffle shapes has been studied numerically. governing equations were solved base on the finite volume method with fluent software. in upper section, oxidation reaction of methanol was occurred and in lower section, steam reforming of methanol was done. two sections were separated with solid part which played as heat exchanger and trans...

Micro Strip Antenna Array has been proposed with high efficiency for wireless communication. Micro strip antenna arrays are widely used in various applications like in wireless communication system, satellite communication, Radar systems, Global positioning systems, Radio Frequency Identification (RFID), Worldwide interoperability for microwave access (WiMax), Rectenna applications, Telemedicin...

In this study, in the removal of macro (P, S, Na, K, Ca, Mg) and micro (Sb, Ba, Co, Cu, Fe, Pb, Mn, Hg, Mo, Se, Ag, Zn) elements in the effluent of Elazig Wastewater Treatment Plant, the efficiency of Lemna minor L. and Lemna gibba L. has been studied comparatively. For this aim, fronds of these plants have been adapted to the effluent of the treatment plant that feeds pilot scale reactors. The...

For gold, the most promising elements for provenance are Platinum Group Elements (PGE), Sn, Te, Sb, Hg, Pb, but also high melting point elements, such as Ta and Nb. Small fragments of native Carpathian gold placer and primary were studied using Synchrotron Radiation X-Ray Fluorescence at ANKA synchrotron. The goal of the study was to identify the trace elements, especially Sn, Sb and Te. The me...

This contribution presents analyses of teachers’ and students’ verbal and gesture productions in classrooms in order to construct knowledge involved in particular contexts. These analyses are based on theoretical positions on knowledge and learning hypotheses. In particular we assume that students’ conceptual understanding of physics is constructed through acquisition of small elements of knowl...

The collection of denarii from the time of development of a Polish medieval state was studied using the proton induced X-ray emission spectroscopy. The major elements detected for these denarii are Ag and Cu, while minor elements such as Pb, Fe, Au, Bi, and Zn may also be present. The aim of the study was to cross-compare the results with a previous micro-X-ray fluorescence data and to perform ...
