dehsalm metamorphic complex located in east of iran consists of regionally metamorphosed rocks intruded by three phases of granitic masses. synkinematic porphyroblasts of garnet from staurolite-garnet schist present well preserved growth zoning. electron microprobe analysis of selected garnets was carried out to interpret the origin and pattern of zoning in amphibolite facies garnets and its im...

A dual-beam coherent feeding system design approach with a non-uniform layout on concentric ring array is described and synthesized. In this case, the based reconfigurable topology composed of set alternated power dividers combiners, providing in-phase outputs. Thus, in paper, two-beam architecture formed by intercalated input signals each circular antenna multi-beam shaping steering features a...

A new algorithm was advanced in this paper to do the auto-layout of the network topology. All the vertexes and edges of a graph are assigned some geometrical properties such as degrees, outerdegrees, coordinate and consistency. Thus, these vertexes will be arranged around the centre of a circle and from the inner circle to the outer circle forming a series of concentric circles. This kind of ar...

this paper presents a novel fully differential (FD) ultra high common mode rejection ratio (CMRR) current operational amplifier (COA) with very low input impedance. Its FD structure that attenuates common mode signals over all stages grants ultra high CMRR and power supply rejection ratio (PSRR) that makes it suitable for mixed mode and accurate applications. Its performance is verified by HSPI...

The Full Adders (FAs) constitute the essential elements of digital systems, in a sense that they affect the circuit parameters of such systems. With respect to the MOSFET restrictions, its replacement by new devices and technologies is inevitable. QCA is one of the accomplishments in nanotechnology nominated as the candidate for MOSFET replacement. In this article 4 new layouts are presente...

the aim of study was to investigate and compare the concentric torque of quadriceps and hamstring muscles and timed-walking test in two groups. thus, one group of healthy subjects and one group of patients with low grade of tibiofemoral osteoarthritis (oa) were selected. concentric torque of quadriceps and hamstring were measured in both groups. besides, pain measurement, timed-walking test, ra...

This paper presents a layout optimization method of the spot locations pencil beam scanning for particle cancer therapy. With technique, is scanned from to in tumor by using magnets. To provide clinically ideal dose distributions and less-invasive treatment patients, both number particles given each should be optimized. However, fixed with lattice pattern many prior studies. We propose derive n...
