(a) Any interested person shall have the right to petition for the issuance, amendment, or repeal of rules published in this part. Any such petition will be considered in a reasonable time. Prompt notice shall be given of the denial in whole or in part of any petition. Except in affirming a prior denial or when the denial is self-explanatory the notice shall be accompanied by a brief statement ...
The main goal of this paper is to propose a probability model for computing probabilities of dismissal of 10b-5 securities class-action cases filed in United States Federal district courts. By dismissal, we mean dismissal with prejudice in response to the motion to dismiss filed by the defendants, and not eventual dismissal after the discovery process. The proposed probability model is a hybrid...
Congress enacted the Americans with Disabilities Act (ADA) to provide persons living with the human immunodeficiency virus (HIV) and other vulnerable populations with legal means of redress against discrimination, yet virtually nothing is known about how the intended beneficiaries have used these protections. This study aimed to describe the epidemiology of ADA charges alleging employment-relat...
AIM Extremely low-frequency electromagnetic fields (ELF-EMFs) have some genotoxic effects and it may alter the mRNA levels of antioxidant genes. The NAD(P)H: quinone oxidoreductase-1 (NQO1) and NQO2 are ubiquitously expressed. Considering that there is no published data on the effect(s) of ELF-EMF (50-Hz) exposure and expression levels of NQO1 and NQO2 in the human MCF-7 cells, the present stud...
The aim of this study was to investigate whether differences in the composition of calcium hydroxide (Ca(OH)2) preparations influence the removal efficiency of irrigation solutions used in combination with filing of the canal. Three Ca(OH)2 preparations were used: Calxyl, Pulpdent paste, and chemically pure Ca(OH)2 mixed with distilled water. Fifty-one single-rooted extracted human teeth were p...
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 ...
This paper describes the application of the so-called normalized standard deviation (NSTD) method to detect edges of gravity anomalies. Using derivative-based methods enhances the anomaly edges, leading to significant improvement of the interpretation of the geological features. There are many methods for enhancing the edges, most of which are high-pass filters based on the horizontal or vertic...
In this paper, modular neural network (MNN) inversion has been applied for the parameters approximation of the gravity anomaly causative target. The trained neural network is used for estimating the amplitude coefficient and depths to the top and bottom of a finite vertical cylinder source. The results of the applied neural network method are compared with the results of the least-squares stand...
In this paper we consider the action of higher derivative gravity up to the second order terms in the scalars made from the Ricci scalar, Ricci and Riemann tensors. We use the Bach- Lanczos identity of the Weyl tensor in four dimensions and show that the solutions of 4-dimensional Einstein equations with cosmological constant term in vacuum, which are known as Einstein metrics, satisfy the fie...
Investigating waves propagation’s equation in the atmosphere is one of the important and widely used issues in various sciences, which has attracted many researchers. A type of propagating waves is an acoustic-gravity wave. These type of waves have a lot of stationarity properties and can be propagate to a high altitude in the atmosphere. The equation of acoustic-gravity wave propagation is a h...
