A total of 1300 endodontic patient charts were analyzed for factors that may have contributed to the failure of the original treatment or the success of the retreatment. Of those surveyed, 667 had recall information of 6 months or more and were used to consider success rates. The remaining cases were analyzed for other information. The findings were tabulated and analyzed by computer for signif...

We report precise measurements of ground-state, Lambda-doublet microwave transitions in the hydroxyl radical molecule (OH). Utilizing slow, cold molecules produced by a Stark decelerator we have improved over the precision of the previous best measurement 25-fold for the F'=2-->F=2 transition, yielding (1 667 358 996 +/- 4)Hz, and by tenfold for the F'=1-->F=1 transition, yielding (1 665 401 80...

A multiple pass A/D conversion technique is proposed for mixed-signal test applications. Only a single on-chip comparator and sample-and-hold circuit is required to digitize repetitive analog waveforms. Simulations show 10 bits of amplitude resolution at 300 MHz for a bipolar comparator design (0.8 μm BiCMOS process), and 10 bits of amplitude resolution at 667 MHz for a CMOS comparator design (...

Poor health-related quality of life (HRQL) is associated with mortality in cardiac patients. Patients (N=667) with poor HRQL after percutaneous coronary intervention had a higher incidence of early (< or =6 months) major adverse cardiac events (MACE) than did patients with good HRQL, whereas there was no difference for late (>6 months) MACE over a 2-year follow-up period. Poor HRQL remained an ...

Following the work of Leutheusser [Physica A 127, 667 (1984)], the solution to the Percus-Yevick equation for a seven-dimensional hard-sphere fluid is explicitly found. This allows the derivation of the equation of state for the fluid taking both the virial and the compressibility routes. An analysis of the virial coefficients and the determination of the radius of convergence of the virial ser...

2014 Crystals of the title compound show a semiconducting behaviour with 03C3 (300 K) ~ 10-3 (03A9 cm)-1. The conductivity results from thermal activation of electrons from defect states in the band gap into the empty conduction band. The susceptibility, however, is large ~ (300 K) = 5 10-4 emu/mole and Pauli-like at T &#x3E; 50 K and not correlated to the conductivity. The location of the elec...

667 A 27 yr old female presented to the Urology department, Institute of Kidney Disease and Research Centre, Ahmedabad, Gujarat, in April, 2014 with bilateral dull aching flank pain, more on left side, early satiety, incapacitating her day-to-day activities for the last two months. She was on antiepileptic drugs for her convulsive episodes since early childhood. Examination revealed protuberant...

Feeding rats with sorbitol, fructose, glycerol and ethanol increases the concentration of serum corticosterone without significantly altering the concentration of insulin. This increase appears to be partly responsible for the increases in the hepatic activity of phosphatidate phosphohydrolase (compared with rats fed glucose or 0.9% NaCI) that has been reported [Sturton, Pritchard, Han & Brindl...

This paper reports tests of the hypothesis that a 10 mse-c. 667 nm. fovea1 teSt flash, presented upon a steady, 8” background, is detected by a pathway whose sensitivity is monotonically related io a linear functional of photoreceptor quantum catch. The hypothesis is tested by (1) measuring incrementthreshold curves for various background wavelenghts, and (2) measuring threshold upon mixtures o...
