Introduction: Osteoporosis is a systemic skeletal disease with a consequent increase in bone fracture. The purpose of this study was to determine skeletal changes induced by two types of exercise therapy in osteoporotic rats. Materials and methods: Among 30 male rats, 6 of them were selected as healthy group, Then Osteoporosis induced in other rats by intraperitoneal injection of 20% ethan...

In this paper two R‑L network simulator configurations employing a single VDDIBA, one resistance and one grounded capacitance are presented. The first configuration is a grounded series resistor-inductor (R‑L) network simulator and the second configuration is intended for grounded parallel resister-inductor (R‑L) circuit simulation. Both the proposed circuits enjoy several beneficial features s...

‎This paper presents the numerical solution for a class of fractional differential equations. The fractional derivatives are described in the Caputo cite{1} sense. We developed a reproducing kernel method (RKM) to solve fractional differential equations in reproducing kernel Hilbert space. This method cannot be used directly to solve these equations, so an equivalent transformation is made by u...

This paper presents an ear model that combines the classical transmission-line cochlear model, the active cochlear partition model, and the active model of a single outer hair cell (OHC). This model can successfully generate “tall and broad” basilar membrane response and otoacoustic emissions. Result show that, owning to the OHC activities, the active cochlear partition has an equivalent resist...

Design-oriented boundary conditions for subharmonic oscillations are of great interest recently. Based on a subharmonic oscillation boundary condition reported in a PhD thesis more than a decade ago, extended new boundary conditions are derived in closed forms for general switching DC-DC converters. Sampled-data and harmonic balance analyses are applied and generate equivalent results. It is sh...

Objectives: The aims of this study were to test whether lightening of the overexposed radiographs improve determination of endodontic files length and whether lightened radiographs are comparable with ideally exposed radiographs. Material and Methods: Four dried human skull coated with soft tissue-equivalent wax used for exposing radiographs of the upper molars. First, the endodontic file was p...

We derive whole series of new integral inequalities of the Hardy-type, with non-conjugate exponents. First, we prove and discuss two equivalent general inequa-li-ties of such type, as well as their corresponding reverse inequalities. General results are then applied to special Hardy-type kernel and power weights. Also, some estimates of weight functions and constant factors are obtained. ...

In this research the relationship between graphitization ability and the carbon equivalent (CE %) of a cast iron have been investigated. The first series of moulds were cast at CE of 3.2% and pouring temperature of 1350°C. The other moulds were cast at different CE% with varying Si content. The graphitization ability( c ) was calculated using the thermodynamics aspects of graphitization and CE%...

The Coach6 software and the CoachLabII+ measuring console coupled with a computer equipped appropriate voltage current sensors were used to determine current-voltage power-voltage characteristics of photovoltaic cells. for single cell cells connected in series parallel tested depending on light intensity. Using simplified theoretical model based one-diode equivalent circuit Shockley diode equat...
