Modelling the Dielectric Constant of Rice Grains
ABSTRACT. A new technique for the measurement of dielectric constant of materials, using a partially filled waveguide cell and a new mixture equation, has been developed which is first tested for teflon and then used to measure the dielectric constant of rice and air mixture in the frequency range of 2.6GHz to 3.9GHz. The values of dielectric constant of rice grain obtained using the mixture mo...
متن کاملON THE FORMATION OF STRAY GRAINS IN DIRECTIONALLY-SOLIDIFIED NI-BASED SUPERALLOYS WITH VARYING CROSS SECTIONS
Formation of stray grain defects particularly around re-entrant features of the turbine blade airfoils is one of the major problems in directional and single crystal solidification processes. In this work, directional solidification tests of the GTD-111 Ni-based superalloy were conducted at different withdrawal velocities of 3, 6 and 9 mm.min-1 using various stepped cylindrical and cubic design...
متن کاملFormation of Calcium H and K Grains
We have simulated the generation of Ca ii H2V bright grains by acoustic shocks. We employ a one-dimensional, non-LTE, radiation hydrodynamic code, with 6 level model atoms for hydrogen and singly ionized calcium. We drive acoustic waves through a stratiied radiative equilibrium atmosphere by a piston, whose velocity is chosen to match the Doppler shift observed in the FeI 396.68 line in the H l...
متن کاملArbuscular mycorrhizal strategy for zinc mycoremediation and diminished translocation to shoots and grains in wheat
Mycoremediation is an on-site remediation strategy, which employs fungi to degrade or sequester contaminants from the environment. The present work focused on the bioremediation of soils contaminated with zinc by the use of a native mycorrhizal fungi (AM) called Funneliformis geosporum (Nicol. & Gerd.) Walker & Schüßler. Experiments were performed using Triticum aestivum L. cv. Gemmeza-10 at di...
متن کاملMolecular Hydrogen Formation on Porous Dust Grains
Recent laboratory experiments on interstellar dust analogues have shown that H2 formation on dust grain surfaces is efficient in a range of grain temperatures below 20 K. These results indicate that surface processes may account for the observed H2 abundance in cold diffuse and dense clouds. However, high abundances of H2 have also been observed in warmer clouds, including photon-dominated regi...
