Sugarcane is cultivated in the wide area in Khuzestan province. In these areas, irrigated sugarcane cultivation consumes more than 30,000 cubic meters per hectare annually. This research was carried out to determine the effect of sugarcane cultivation on the soil development process and forms of iron oxides. Different sugarcane fields with different utilization times were selected and soil phys...

Minimal pairs of definition were introduced by Alexandru, Popescu and Zaharescu [3], [4], [5] to study residue transcendental extensions. In this paper we obtain analogous results in the value case. We introduce notion minimal fields for valuation extensions show that they share some common ramification theoretic properties. The connection between implicit constant is also investigated. Further...

The problem of unbounded uniaxial chiral omega media in the presence of both static electric and magnetic point charges is investigated. For this purpose scalar electric and magnetic potentials in these media are introduced. Using these potentials, the corresponding electric and magnetic fields are determined. The similar problem of static electric and magnetic current sources with the goal of ...

Electrodynamic space tethers offer the opportunity for in-space “propellantless” propulsion around planets with a magnetic field and an ionosphere. This propulsion is accomplished by converting the magnetic force on the tether current into propulsive or drag thrust to either increase or decrease the orbital energy of the spacecraft system. To validate electrodynamic-tether thrusting, we must be...

Magnetohydrodynamics MHD concerns the motion of a conducting fluid in an electromagnetic field with a very wide range of applications. The dynamic motion of the fluids and the magnetic field strongly interact each other, and thus, both the hydrodynamic and electrodynamic effects have to be considered. The governing equations of the plane magnetohydrodynamic compressible flows have the following...
