INTRODUCTION This study evaluated the working length (WL) modification after instrumentation with WaveOne Primary (Dentsply Maillefer, Ballaigues, Switzerland) reciprocating files and the incidence of overinstrumentation in relation to the initial WL. METHODS Thirty-two root canals of permanent teeth were used. The angles of curvature of the canals were calculated on digital radiographs. The ...

Present study describes the length-weight (LWR) and length-length (LLR) relationships of a freshwater catfish Eutropiichthyes vacha Hamilton from Indus River, Sindh, Pakistan. A total of 281 specimen of E. vacha were collected from fisherman?s catch from February 2005 to January 2006, are used for this study. The parameters a and b of the length-weight relationship were calculated as W= aLb are...

to investigate the genotypic and phenotypic relationship between characteristics affecting tomato fruit weights, eleven tomato lines were compared in a rcb design with three replications. the anova showed that the difference among lines was significant for all characteristics. there was a significant phenotypic and genotypic correlations between fruit weight and most of the characteristics. the...

Three-dimensional wave propagation simulations and experiments show that the gain exponent, an often used metric to assess the likelihood of stimulated Brillouin scatter, is insufficient and must be augmented with another parameter, Nr, the ratio of the resonance length, Lres, to the laser speckle length. The damping rate of ion acoustic waves, ν, and thus Lres, which is proportional to ν, are ...

The ability of rabbit trachealis to undergo plastic adaptation to chronic shortening or lengthening was assessed by setting the muscle preparations at three lengths for 24 h in relaxed state: a reference length in which applied force was approximately 1-2% of maximal active force (P(o)) and lengths considerably shorter and longer than the reference. Passive and active length-tension (L-T) curve...

In this paper we present multifrequency VLA observations of the giant radio galaxy 3C 449. High resolution and sensitivity data were obtained in total inten-The source is characterized by an unresolved core, two opposite symmetric jets, and very extended lobes. These new images show the source morphology in great detail, in particular we detect plumes and wiggles in the low brightness lobes. Th...

In this paper we present multifrequency VLA observations of the giant radio galaxy 3C 449. High resolution and sensitivity data were obtained in total intensity and polarized flux at 1.365, 1.445, 1.465, 1.485, 4.685, 4.985 and 8.385 GHz. The source is characterized by an unresolved core, two opposite symmetric jets, and very extended lobes. These new images show the source morphology in great ...

introduction: post and core has been considered for endodontically treated tooth, especially in cases with severe damage crowns. recently fiber reinforced composite posts (frc post) have been used in the treatment of endodontically treated teeth. because the length and diameter of posts are effective in stress distribution, the purpose of this study is to evaluate the effect of length and diame...
