Differential precession due to the planet's quadrupole moment tends to destroy the alignment of particles in inclined rings. We propose that alignment is maintained by the self-gravity of the ring. This hypothesis predicts that 8i/8a>0 across the ring. If 8i/i0 <(1, 8e/e0 <(1, a8i/8a<(1, and a8e/8a< 1, a further prediction is that 8i/i0 = 8e/e0 • The a and /3 rings of Uranus may be used to test...

AIM The aim of this study was to determine the effect of sodium bicarbonate irrigation versus normal saline irrigation in patients undergoing a laparoscopic cholecystectomy. BACKGROUND Pain in patients undergoing laparoscopic cholecystectomy is the most common complaint, especially in the abdomen, back, and shoulder region. PATIENTS AND METHODS In a double blind randomized clinical trial, 1...

Reclaimed water has emerged as a potential irrigation solution to freshwater shortages. However, limited data exist on the persistence of antibiotics in reclaimed water used for irrigation. Therefore, we examined the fate of nine commonly-used antibiotics (ampicillin, azithromycin, ciprofloxacin, linezolid, oxacillin, oxolinic acid, penicillin G, pipemidic acid, and tetracycline) in differentia...

OBJECTIVES To evaluate effectiveness of the apical negative pressure irrigation (EndoVac), passive ultrasonic irrigation (PUI), and conventional needle irrigation (CI) systems on smear layer (SR) removal. MATERIALS AND METHODS Sixty single-rooted canines were prepared using NiTi rotary files and subjected to different irrigation regimens: EndoVac with NaOCl (Group 1) or NaOCl/EDTA (Group 2); ...

The geometry of the LMC bar is studied using the dereddened mean magnitudes of the red clump stars ( ) I0 from the Optical Gravitational Lensing Experiment II catalog. The value of is found to vary in the east-west I0 direction such that both the east and the west end of the bar are closer to us with respect to the center of the bar. The maximum observed variation has a statistical significance...

OBJECTIVE Although standard method has not been established for the chronic subdural hematoma (CSDH), burr-hole trephination and closed system drainage with or without irrigation has been widely accepted as the treatment of choice. The aim of this study is to analysis the post-operative recurrence rates after burr-hole trephination of the CSDH according to the conduction of irrigation. METHOD...

Although rainfall in the United States Mid-South is sufficient to produce corn (Zea mays L.) without irrigation in most years, timely irrigation has been shown to increase yields. The recent interest in ethanol fuels is expected to lead to increases in US corn production, and subsurface drip irrigation (SDI) is one possible way to increase application efficiency and thereby reduce water use. Th...

OBJECTIVES/HYPOTHESIS To compare efficacy and outcome of daily saline irrigation versus saline/gentamicin for treating chronic rhinosinusitis (CRS). STUDY DESIGN Prospective, randomized, double-blinded study. METHODS Forty children diagnosed with CRS were enrolled. Patients were randomized to once-daily irrigation with saline or saline/gentamicin for 6 weeks. Treatment outcomes were measure...

An implicit surface is defined as the zero set of a scalar function over 3-space. Sign of implicit function determines whether a point is inside or outside the implicit surface: f (P )  = 0 P is on the surface. < 0 P is inside the surface. > 0 P is outside the surface. An algebraic function is an implicit function where the function is polynomial. By using an A-patch representation of algebra...

In this study, using the energy momentum definitions of Einstein, Møller, Bergmann-Thomson, Landau-Lifshitz and Papapetrou we compute the total energy-momentum distribution (due to matter and fields including gravitation) of the universe based on general Bianchi type I-III-V-V I0 spacetime and its transforms type I, III, V, V I0 metrics, respectively. The energy-momentum densities are found exa...
