Many numerical models of magnetospheric dynamics treat the ionosphere as an inner boundary condition. These models have traditionally used the current continuity condition, treating the ionosphere as a sheet current in which the electric field is electrostatic. A more general boundary condition is suggested that not only is more complete, but also straightforward to implement. Results from a mo...

background: the use of electric current during application of etch-and-rinse adhesive systems has been recently introduced to decrease microleakage. this study investigated the effects of an electric field produced by an experimental device for the application of a two-step etch-and-rinse adhesive on moist dentin surface. methods: sixty freshly extracted human premolars were used for this study...

The slip effect on hydromagnetic rotating flow of viscous fluid through a porous space is investigated. The fluid is electrically conducting with the consideration of Hall current. The entire system rotates about the axis normal to a porous plate of uniform suction or injection with uniform angular velocity. The closed form solution is obtained using Laplace transform technique. The analytical ...

BACKGROUND Business owners in the Republic of Korea must take part in the workers' general health examination. However, there have been few formal analyses of the uptake of this examination by employees. In the present study, we examined the rates of participation in medical examinations according to age group, health insurance type, and enterprise size, and then compared these results with tho...

In the previous chapters, instantaneous p-q theory was used for reference current extraction. This approach has fast response and the computational time required is also small. But, its performance under noisy voltage condition is found to be not satisfactory. In this chapter, a frequency domain based method is proposed for reference current extraction which is suitable for noisy voltage condit...

The use of electrically conductive adhesives as interconnection materials in electronic assembly process is increasingly becoming a vital part of the electronics industry. Flip-chip joining technique using conductive adhesives has been identi®ed as a key technology for future electronics assembly and manufacturing. The purpose of the present work is to investigate optimum conditions to achieve ...

Vibration analysis does not cover all defects able to affect a rotating machine, including those that induce torque or instantaneous rotation speed fluctuations. Indeed the vibrational energy contributions of this type of defects such as a natural and gradual degradation of the gears are often weak. Therefore the appearance of these defects is very difficult to detect from the vibrational energ...

Recently, nonequilibrium dynamical mean-field theory was developed as a new technique to solve the bulk nonequilibrium many-body problem. The computational effort needed to solve the nonequilibrium problem in the bulk is similar to the efforts needed to solve the inhomogeneous multilayered problem for current flow perpendicular to the planes. Because the leads provide the appropriate boundary c...

BACKGROUND Thrombotic thrombocytopenic purpura (TTP) and haemolytic uraemic syndrome (HUS) are thrombotic microangiopathies (TMAs). They are generally diagnosed and treated by plasmapheresis in the presence of non-immune haemolytic anaemia and thrombocytopenia. Yet, many individuals admitted in our hospital for athrombocytopenic renal failure of unknown cause were reported to have TMA as main l...
