a new model is proposed in this research to calculate the longitudinal strengthof unidirectional e-glass reinforced polymer composites exposed to sulfuricacid environment, using a micromechanics model. in the proposed method,it is assumed that the residual strength of the degraded composites under acidic environment can be calculated by knowing the degraded strength properties of the constituen...

OBJECTIVES This study evaluated the maximum depth and percentage of irrigant penetration into dentinal tubules by passive ultrasonic irrigation (PUI). MATERIALS AND METHODS Thirty extracted human teeth were instrumented and divided into three groups. According to final irrigation regimen, 5.25% sodium hypochlorite (Group A, NaOCl), 2% chlorhexidine (Group B, CHX) and saline solution (Group C,...

Muon-spin rotation (μSR) studies of the oxygen isotope (O/O) effect (OIE) on the in-plane magnetic field penetration depth λab in cuprate high-temperature superconductors (HTS) are presented. First, the doping dependence of the OIE on the transition temperature Tc in various HTS is briefly discussed. It is observed that different cuprate families show a similar doping dependence of the OIE on T...

We present a novel penetration depth estimation algorithm based on the use of deformed distance fields for simulation of non-penetrating flexible bodies. We assume that the continuum of non-rigid models are discretized using standard techniques, such as finite element methods. As the objects deform, the distance fields are deformed accordingly to estimate penetration depth, allowing enforcement...

We report the finding of a novel pairing state in newly discovered superconductor Na2Cr3As3. This material has non-centrosymmetric quasi-one-dimensional crystal structure and is superconducting at TC∼ 8.0 K. find that magnetic penetration depth data suggests presence nodal line pz-wave with zero moment using transverse-field muon-spin rotation (TF-μSR) measurements. The gap observed Na2Cr3As3 c...

The ab-plane reflectance of a Nd1.85Ce0.15CuO4 single crystal (Tc 1⁄4 23 K) has been measured from < 30 to 9500 cm above and below Tc, and the optical properties calculated from a Kramers–Kronig analysis. A rich phonon spectrum is observed with some new spectral features appearing below < 100 K. The normal-state optical conductivity may be described by a Drude-like component and an overdamped m...
