Effects of static electropulsing on microstructure and elongation of the ZA 22 alloy were studied by using scanning electron microscopy and transmission electron microscopy techniques. It was found that the current density of electropulsing treatment (EPT) was one of the factors that influenced microstructural changes and dislocation structure in the EPT alloy. The identity of the microstructur...

The enhanced parameters tuning (EPT) algorithm is applied to adjust the parameters of 802.11e, i.e. arbitration inter frame space (AIFS), Contention window minimum (CWmin) and Contention window maximum (CWmax). The EPT tuning algorithm is proposed with the simple and effective adjustment in the priority combinations strategy to achieve the high quality of service (QoS). The internal competition...

Analysis of a single kick sample from a 2 order stream in Guilford, NY of known water quality showed slight variation among three 100 fixed-count subsamples in calculating EPT Richness at family and genus level of taxonomic resolution. EPT (Ephemeroptera, Plecoptera and Trichoptera) richness of one subsample varied enough to assign the site to a water quality level below other subsamples when c...

INTRODUCTION The aim of this study was to compare the clinical accuracy, reliability, and repeatability of laser Doppler flowmetry (LDF), an electric pulp test (EPT), and various thermal pulp sensibility tests. METHODS Pulp tests were done on 121 teeth in 20 subjects by using LDF, EPT, and thermal pulp testing (CO(2), Endo Frost [EF], Ice) during 2 or 3 test sessions with at least 1-week inte...

A stable Exponential-Polynomial-Trigonometric (EPT) probability density function is fitted to a large set of financial data. The class of EPT functions have a strictly proper continuous time rational transform. An isometry is used to derive its discrete time transfer function, also rational. This function can be written in terms of Fourier coefficients which are used as inputs to RARL2. A minim...

BACKGROUND. Accurate determination of the pulp status is the most important part of conservative pulp therapy. AIM. The aim of this study was to assess the ability of thermal and electrical pulp tests to assess the pulp status in primary teeth. DESIGN. Seventy-eight primary molar teeth in 36 children were investigated. Fifty-six teeth had unknown pulp status in need of endodontic treatment, and...

Estrogens, both endogenous and exogenous, lower the fasting levels of the independent risk factor for cardiovascular disease homocysteine. The mechanism behind this observation remains unclear. In a randomized, placebo-controlled, double-blind study, 25 postmenopausal women with a screening homocysteine concentration above 10 micromol/liter were included. We investigated the influence on homocy...

In recent years, electronic power transformer (EPT), which is also called solid state transformer, has attracted great interest and has been used in place of the conventional power transformers. These transformers have many important functions as high unity power factor, low harmonic distortion, constant DC bus voltage, regulated output voltage and compensation capability. In this study, propos...

Chemical analysis of the culture filtrates of Fusarium culmorum CMI 14764 has demonstrated the presence of seven trichothecene mycotoxins. Major metabolites are 3-acetyldeoxynivalenol and 7 alpha, 8 alpha-dihydroxycalonectrin, with 3,15-diacetyldeoxynivalenol, deoxynivalenol, calonectrin, isotrichodermin and 12,13-epoxytrichothec-9-ene (EPT) as minor products. The occurrence of the rarely encou...
