Background: Acoustic noise is one of the universal pollutants of modern society. Although the high level of noise adverse effects on human hearing has been known for many years, non-auditory effects of noise such as effects on cognition, learning, memory and reading, especially on children, have been less considered. Factors which have negative impact on these features can also have a negat...

The objective was to test the validity of serial position effects (SPE’S) scoring of the Rey Auditory Verbal Learning Test. The RAVLT, a multi-trial free recall test, is a much used clinical method for assessing memory performance. The method of scoring, however, obfuscates that two memory functions underlie free recall. This is suggested by serial position effects (SPE’S) of single-trial free ...

One of the most basic distortions created by the double taxation of corporate income is the disincentive to incorporate. In this paper, we investigate the extent to which the aggregate allocation of assets and taxable income in the U.S. between corporate vs. non-corporate forms of organization during the period 1959--86 has responded to the size of the tax distortion discouraging firms from inc...

The study focuses on an evaluation of the performance of activated bauxite mines in Yazd province in order to remove fluoride from drinking water. Materials and Methods: This study was an experimental one and conducted on synthetic samples a...

Late Pleistocene–Holocene rocks from the western part of Cocos-Nazca Spreading Centre (C-NSC) include ferromanganese crusts that elucidate geochemistry and mineralogy a deep-sea geological setting. Six representative Fe-Mn crust samples were studied using petrological methods, such as optical transmitted light microscopy, energy dispersive X-ray fluorescence spectrometry, inductively coupled pl...

Ferromanganese (Fe-Mn) crusts are potential marine deposits for many high-tech metals and exciting proxies recording the oceanic paleoenvironment. During their growth, phosphatization generally occurs, causing remobilization reorganization of elements minerals in Fe-Mn crusts. Rare earth plus yttrium (REY), well-known critical new emerging technologies, as well valuable geological proxies, impo...
