In order to assess the limitations imposed on a cochlear implant system by a wearable speech processor, the parameters extracted from a set of 11 vowels and 24 consonants were examined. An estimate of the fundamental frequency EF 0 was derived from the zero crossings of the low-pass filtered envelope of the waveform. Estimates of the first and second formant frequencies EF 1 and EF 2 were deriv...

OBJECTIVES The hypoalgesic effect of electroacupuncture (EA) was directly compared with the analgesic effect of pharmacological interventions using the submaximum effort tourniquet technique (SETT). METHODS 125 healthy subjects (mean age 24.44±4.46 years; 62.4% female, 37.6% male) performed SETT at baseline and under one of five experimental conditions (n=25 per group): EA (2 Hz with burst pu...

Despite this growing adoption of enterprise architecture (EA), there has been little research that provides compelling empirical evidence of the EA impact on organizational performance. We argue that the lack of strong empirical evidence is due to the complexity of EA configurations and the limitations of the traditional correlation-based methods for uncovering the complex relationships. This r...

Based on interviews with a number of architects and managers from a wide range of organizations, we characterize how EA is perceived and applied in practice. The key aspects of how EA is perceived in practice are that EA is: a means of abstraction, a means of communication, and a governance instrument. The key critical success factors for applying EA in practice are: the acceptance of EA driven...

Successful economic development depends on the rational use of natural resources and on reducing as far as possible the adverse environmental impacts of development projects. Environmental assessment (EA) is a primary tool for achieving this objective, by inserting critical environmental information into the process of project identification, preparation, and implementation. Economic analysis, ...

Background: Esophageal Atresia and Tracheo-Esophageal Fistula (EA/TEF) occurs sporadically and its etiology is poorly understood. We observed six cases of EA/TEF within three weeks of October 2007 at the Lagos University Teaching Hospital (LUTH), Nigeria. Aims: To analyze the monthly trends of presentation of EA/TEF at the LUTH from 2002-7, test the hypothesis that the October figures were not ...

Since the introduction of the EA process and subsequent development of EA methodologies and legislative provisions, the analysis of alternatives has been one of the main tenets of EA policy and procedures. Indeed, a thorough, unbiased and transparent assessment of investment alternatives from an environmental and social perspective (as well as a technical and economic standpoint) is one of the ...

In this study, we investigated the molecular mechanisms underlying the anti-apoptotic properties of electroacupuncture (EA) in a rat model of middle cerebral artery occlusion (MCAO). Treatment with 2 Hz EA (1 mA) resulted in a markedly reduced infarct area after stroke, particularly in the middle region of the brain. Treatment with EA resulted in a significant decrease in the number of apoptoti...

The aim of this study was to demonstrate the cholesterol-lowering effect of electroacupuncture (EA) at the acupoint of Fenglong (ST40) in mice and to investigate its molecular mechanism by using genome-wide gene expression profile analysis. Mice with hypercholesterolemia induced by a high-cholesterol diet were randomly divided into EA at ST40 group (EG), EA at non-acupoint group (ENG), and simv...

N-propylsalicylidene based on silica as ion exchanger (IE) was used for the separation by complexation of Mn2+, Co2+, Ni2+, Cu2+, Hg2+, Cr3+, Fe3+, and UO22+ from their parent solutions. IE and its metal complexes are characterized by elemental analysis, electronic and infrared spectra, in addition to thermal analysis in atmospheric pressure. The mode of chelation and the proposed geometric str...
