AIM To analyse the gutta-percha filled area of C-shaped molar teeth root filled with the modified MicroSeal technique with reference to the radiographic features and the C-shaped canal configuration. METHODOLOGY Twenty-three mandibular second molar teeth with C-shaped roots were classified according to their radiographic features as: type I--merging, type II--symmetrical and type III--asymmet...
Samples of concrete contain various waste materials, such as iron particulates, steel balls of used ball bearings and slags from steel industry were assessed for their anti-radiation attenuation coefficient properties. The attenuation measurements were performed using gamma spectrometer of NaI (Tl) detector. The utilized radiation sources comprised 137Cs and ⁶⁰Co radioactive elements with photo...
OBJECTIVES To investigate right ventricular diastolic function in systemic sclerosis (SSc) and its relation to clinical features of the disease. METHODS Seventy seven unselected SSc patients and 33 healthy subjects were submitted to echocardiography and echo Doppler study to assess left and right systolic as well diastolic function and to estimate maximal arterial systolic pulmonary pressure ...
The purpose of this study was to assess the efficacy of the thermoplastic filling techniques, Touch'n Heat®, TC® System and Tagger's Hybrid Technique, in oval-shaped canals at the apical third.Thirty-three human uniradicular lower pre-molar teeth were treated by the reciprocating movement technique and were subsequently split into 3 groups, according to the filling technique performed:Touch'n H...
simulation of grinding circuits has being performed from 30 years ago and is also to be more complete and powerful approach with improvement of mathematical models which simulate various processing units/machines. the modeling and simulation of various mineral processing circuits are presently performed. in order to simulate the present grinding circuits of esfordi phosphate processing plant, a...

In order to investigate the effect of different irrigation regimes on some agronomic and physiological characters of three chickpea cultivars (Jam, 301 and Pirooz), a field experiment was conducted in 1998 at the Agricultural Research Farm of Tabriz University, Tabriz, Iran. A split plot experiment based on a randomized complete block design with three replications was used, in which irrigation...
