introduction: mineral trioxide aggregate (mta) is an endodontic material with different clinical applications e.g. root-end filling, pulp capping and perforation repair.  it has been reported to possess antimicrobial and antifungal activities. the aim of this study was to examine the effect of white mta on formalin-induced hyperalgesia in a rat with inflammatory pain. materials and methods: inf...

in the response phase the most important step is to assess disaster after occurrence. by disaster assessment, we can obtain all the needed information for controlling, decision-making and also disaster planning. lack of disaster assessment causes you to make unsuitable decisions ba sed on limited or inadequate data which leads to imperfect disaster response. according to ifrc, disaster response...

phase sensitive detector described here has two principal applications: a- to produce a d.c out put proportional to- the amplitude of an incoming a,c signal and indicate, by the outut polarity, the phase of the signal with respect to an internal reference. b- to detect the presence of a signal of known phase and frequency which would otherwise be lost in «background noise» and to measure its am...

In the context of the non-abelian Fourier transform, the natural extension of the amplitude and phase response to a convolution by a given filter mask are shown to be the polar decompositions of the Fourier transform matrices. A specific example regarding amplitude and phase response of a certain filter mask over the symmetric group S3 is given.

Stratigraphic inverse modeling using the SEDPAK stratigraphic simulator established the size of the physical parameters that together controlled the development of the stratal patterns in the late Tertiary Ulleung Basin, East (Japan) Sea. The modeling results provided a quantitative geohistory of the basin. This included the dimension of variations in rates of tectonic subsidence (or uplift) an...
