A method of determining material parameters associated with a conductor using four points includes injecting and extracting alternating current into the plate using current-carrying wires operatively connected to two of the four points, measuring potential drop between the remaining two of the four points, and calculating the material parameters. The conductor can be of a homogenous material, a...

INTRODUCTION The growth/differentiation factors (GDFs) are a subgroup of the Bone Morphogenetic Proteins (BMPs) best known for their role in joint formation and chondrogenesis [1,2]. Mice deficient in one of these signaling proteins, GDF-5, exhibit numerous skeletal abnormalities, including shortened limb bones [3]. Because longitudinal bone growth is achieved via the process of endochondral os...

Introduction The wave propagation in magneto-electro-elastic materials has gained considerable importance since last decade. The electro-magneto-elastic materials exhibit a desirable coupling effect between electric and magnetic fields, which are useful in smart structure applications. These materials have the capacity to convert one form of energy namely, magnetic, electric and mechanical ener...

Abstract Ansys software is used to simulate the welding process of boring bar new cylinder head machine. The indirect coupling method analyze temperature field, then stress field and deformation. It found that for double support structure, highest occurs at outer stiffened plate small diameter end, lowest both ends inner structure. deformation whole structure mainly comes from axial deformation...

A laboratory test with a flow-through system was designed and its applicability for testing antifouling paints of varying efficacies was investigated. Six different formulations of antifouling paints were prepared to have increasing contents (0 to 40 wt.%) of Cu2O, which is the most commonly used antifouling substance, and each formulation of paint was coated on just one surface of every test p...

The ALMA front-end cryostat is a cylinder 1-m in diameter and 0.5-m high which holds up to 10 receivers operating in different frequency bands for full details see [1]. Figure 1 shows the cryostat in a preliminary mounting frame which allows initial RF measurements to be made using the adjacent electronics and control racks. Figure 2 shows a close-up picture of the top of the cryostat with the ...

Male and female leaves and fruits of eleven different taxons of Iranian conifers (Cupressus sempervirens var. horizontalis, C. sempervirens var. sempervirens, C. sempervirens cv. Cereifeormis, Juniperus communis subsp. hemisphaerica, J. excelsa subsp. excelsa, J. excelsa subsp. polycarpos, J. foetidissima, J. oblonga, J. sabina, Platycladus orientalis and Taxus baccata) were collected from diff...

A new ultrasonic suction pump is described in this paper. The pump uses suction force of the rigid cylinder tube vibrating at an ultrasonic frequency and has no physically moving parts. The pump is consists of a longitudinal bolt-clamped Langevin transducer (BLT) combined with a stepped horn working at its resonance frequency of 24 kHz. A glass tube of the half-wavelength-resonance length is gl...

We review recent developments in the Casimir effect which arises in quantization volumes restricted by material boundaries and in spaces with non-Euclidean topology. The starting point of our discussion is the novel exact solution for the electromagnetic Casimir force in the configuration of a cylinder above a plate. The related work for the scalar Casimir effect in sphere-plate configuration i...
