This study evaluated the effectiveness of a dentin bonding agent as a barrier to prevent coronal microleakage and examined the effect of a eugenol-based sealer on the sealing ability of this resin adhesive. Fifty-one extracted human mandibular molars were incorporated in a model system using an oral streptococci as a microbial marker. Group 1 consisted of 15 teeth that were obturated with only ...

In this paper, three SIAM-Review problems selected from Vol. 34 (1992) are reconsidered and treated using methods according to my own vision on them. 1 Consider the functions S(v) and C(v) defined as the sums of two infinite double series : S(v) = +∞ m=0 +∞ n=1 (−1) m+n sin(2v √ m 2 + n 2) √ m 2 + n 2 , (1.1) C(v) = +∞ m=0 +∞ n=1 (−1) m+n cos(2v √ m 2 + n 2) √ m 2 + n 2 , (1.2) whereby it is in...

A pulsing circuit is designed and constructed capable of raising up to +6.7kV between plates of a small (~50cm side length) spark chamber. The device is triggered by the ~2V output of a cosmic ray detection device, and its overall gain of ~1:3000 is achieved by a sequence of amplifiers and fast switching devices – namely a Bipolar Junction Transistor (BJT), Insulated Gate Bipolar Transistor (IG...

In this paper we propose a promising multiantenna scheme specifically suitable for hybrid Code & Time Division Multiplex (CTDM) high speed shared channels commonly employed in 3GPP and 3GPP2 standards (HSDPA/1xEVDO(HDR)/1xEVDV). The scheme is called Phase Sweep Transmit Diversity (PSTD) and was originally proposed for power controlled dedicated voice channels. PSTD is shown to provide the benef...

A longitudinal magneto-optical Kerr effect and magnetization-induced second-harmonic generation (MSHG) of light (at 2v) have been measured in a SiO2/Fe96Si4/Dy30Fe58Co12/glass exchange-coupled magnetic bilayer system with competitive anisotropies. Theoretical MSHG predictions in this structure that give rise to an effect proportional to magnetization components and that are allowed by an electr...

OBJECTIVE To analyze the effect of a single bout of resistance exercise on cardiac autonomic modulation in patients with peripheral artery disease. METHODS Fifteen patients with peripheral artery disease (age: 58.3±4.0 years) underwent the following sessions in a random order: resistance exercise (three sets of 10 repetitions of the six resistance exercises with a workload of 5-7 in the OMNI-...

Let q be any integer ≥ 2. In this paper, we consider the q-ary ndimensional cube whose vertex set is Znq and two vertices (x1, . . . , xn) and (y1, . . . , yn) are adjacent if their Lee distance is 1. As a natural extension of identifying codes in binary Hamming spaces, we further study identifying codes in the above q-ary hypercube. We let M t (n) denote the smallest cardinality of t-identifyi...
