background and aim of study: long span is seen in many clinical situations, treatment planning options of these cases are difficult and may require: fpd, rpd or isp. each option has its own disadvantages: mechanical, patient relief and cost respectively. this article will evaluate the stress distribution of another treatment option which is adding a single supporting implant to the fpd by using...

attempts to obtain experimental values for the kinetic parameters of phenanthridine oxidation by guinea pig or rabbit liver aldehyde oxidase using common spectrophotometric methods have not been successful due to a lower limit of detection. in the present study, a new spectrofluorimetric assay in combination with a multivariate calibration method for enzymatic kinetic study of aldehyde oxidase ...

chemometric techniques in spectral analysis have gained importance in the quality control of  the drugs mixtures and pharmaceutical formulations containing two or more drugs with overlapping spectra. since theophylline and etophylline have common chromophore, they cannot be analyzed simultaneously using conventional uv methods. simultaneous spectrophotometric determination of etophylline and th...

background: assessment of prosthetic needs in a special population would aid in planning the oral health service programs. the aim of this study was to assess the dental prosthetic status and prosthetic needs in a sample of green marble mine laborers of udaipur, india.     methods: the study population comprised of 513 green marble mine laborers who were divided into four age groups (15-24, 25-...

here, a new method called aboodh transform homotopy perturbation method(athpm) is used to solve nonlinear partial dierential equations, we presenta reliable combination of homotopy perturbation method and aboodh transformto investigate some nonlinear partial dierential equations. the nonlinearterms can be handled by the use of homotopy perturbation method. the resultsshow the eciency of this...

objective: this in vitro study evaluated the fracture strength and bending amount of twotypes of fiber reinforced composite (frc) and cast metal frameworks used for fabrication of inlay fixed partial dentures (ifpds). materials and methods: seventy-two extracted first maxillary premolars and molars (36 each) were embedded in acrylic resin to represent a missing of second maxillary premolar. frc...

background: we evaluated the diagnostic value of electroencephalography (eeg), video-eeg monitoring (vem) and magnetic resonance imaging (mri) of the brain with epilepsy protocol in patients with complex partial epilepsy. methods: forty-two consecutive patients underwent complete neurological examination, eeg, and mri with a modified epilepsy protocol. a subset of these patients (n = 29) also u...

one of the ecient and powerful schemes to solve linear and nonlinear equationsis homotopy analysis method (ham). in this work, we obtain the approximate solution ofa system of partial dierential equations (pdes) by means of ham. for this purpose, wedevelop the concept of ham for a system of pdes as a matrix form. then, we prove theconvergence theorem and apply the proposed method to nd the a...
