BACKGROUND Many physicians believe Medicaid patients are more likely than non-Medicaid patients to file malpractice claims. This study examines the accuracy of this belief in regard to obstetric malpractice claims. METHODS Claims filed between January 1982 and June 1988 from the major malpractice insurer in Washington State were used to compare obstetric malpractice claims filed on behalf of ...
In this research, the effect of the uniform electric field on the ground-state of a centered hydrogenic donor impurity in a GaAs/AlAs spherical quantum dot was studied using infinite potential model. In presence of strong electric field, due to the stark effect (perturbing electric field), the ground state energy would increase linearly. In presence of weak electric fields, the normalized bind...
1. Abstract Electrical Impedance Tomography is a soft–field tomography modality, where image reconstruction is formulated as a non-linear least-squares model fitting problem. The NewtonRahson scheme is used for actually reconstructing the image, and this involves three main steps: forward solving, computation of the Jacobian, and the computation of the conductivity update. Forward solving relie...
This paper presents a numerical model for a full scale hybrid particulate collector (HPC), which combines the ESP technology and the filtration technology together. The corona discharge is solved by using a finite volume method. The turbulent flow equations are solved by using the Fluent package. The effect of the electric field on the fluid field named electrohydrodynamic is considered. The pa...
Reactive power plays an important role in supporting the real power transfers by maintaining voltage stability and system reliability. It is a critical element for a transmission operator to ensure the reliability of an electric system while minimizing the cost associated with it. The traditional objectives of reactive power dispatch are focused on the technical side of reactive support such as...
The history of indentured migration to seventeenth-century English America relies heavily on a single body sources known as the London record, collection contracts and registrations servants who emigrated from capital between 1683 1686. Of original 1,000 contracts, 189 have long been considered be missing. This article uses methods study paperwork print culture demonstrate that Huntington Libra...
Through this lecture note we try to provide a portal into the emerging filed of kernelization. We exhibit through examples various tools to prove both lower and upper bounds on the kernel sizes.
Bulletin, any person may give notice to the European Patent Office of opposition to that patent, in accordance with the Implementing Regulations. Notice of opposition shall not be deemed to have been filed until the opposition fee has been paid.
In electric arc furnace steelmaking units, the essential parameters are reducing price, increasing production and decreasing environmental pollution. Electric arc furnaces are the largest users of electric energy in industry. The most important techniques that can be used to reduce the electric energy consumption in electric arc furnaces are scrap preheating, stirring, use of burners and hot ch...
