The descriptive epidemiologic features of bladder cancer and lung in Los Angeles County were studied for the period 1972-1976, using data from County/University Southern California Cancer Surveillance Program. incidence pattern was found to differ markedly observed cancer. As expected, closely paralleled known epidemiology cigarette smoking; addition, it consistent with expected an occupationally linked disease. In contrast, indicated that factors other than smoking occupational exposures...

Atrial fibrillation (AFIB) is the most common complication following coronary artery bypass grafting (CABG). Despite three decades of recognition, efforts to reduce high incidence reported (15%-30%) have been largely unsuccessful. Reasons for postoperative AFIB are likely multifactorial. As a result, we defined multidrug prophylaxis based on agents known be individually effective. This method was applied prospectively series consecutive CABG patients with goal reducing new-onset...

A bstract : Equations that describe partial molal volume effects were used to produce a methane‐water‐hydrate phase diagram which includes T, P , and aqueous methane concentrations. This allows prediction of gas exsolution as result local biogenesis or methane‐containing water simply rises through sediments. Such exsolved can be trapped in homogeneous sediments by relative permeability effects. Hydrate stability conditions when the system is not at liquid‐vapor saturation also determined.

Electric potential measurement (EPM) technology offers an attractive alternative to conventional nondestructive evaluation for monitoring crack growth in harsh environments. Where NDE methods typically require localized human interaction, the EPM technique developed at Idaho National Engineering and Environmental Laboratory can be operated remotely automatically. Once a crack-like defect is discovered via means, applied monitor local size changes. This of particular interest situations where...

In this paper, we describe a physical mechanism that relates measurable behavior of rigid oscillator device to the properties surrounding acoustic medium. The under consideration is rotating mass imbalance within an enclosed shell immersed in unbounded fluid. It assumed driven by electromagnetic motor excited given dc voltage. If nonlinearities are ignored, steady-state operational frequency such determined balance between applied and opposing frictional torque on imbalance. retained, it...

A bstract Background: Atrial fibrillation (AFIB) is the most common complication following coronary artery bypass grafting (CABG). Despite three decades of recognition, efforts to reduce high incidence reported (15%‐30%) have been largely unsuccessful. Reasons for postoperative AFlB are likely multifactorial. As a result, we defined multidrug prophylaxis based on agents known be individually effective. This method was applied prospectively series consecutive CABG patients with goal reducing...

"Jumping Stump" syndrome is a rare postoperative complication seen in the residual limb of amputees, with only few cases documented literature. It has been defined as peripherally induced movement disorder leading to either dystonia, myoclonus, tremors, or choreiform movements amputated limb. often associated significant discomfort and an inability ambulate prosthetic Treatment options remain inconclusive at this time. We present case young female transtibial amputee following revision...

Abstract Although amazingly simple in concept, the downhole orbital vibrator is assuming an important and growing role wellbore applications that include subsurface diagnostic imaging concepts. The was first intended as part of a low-frequency shear-wave logging tool. It quickly found more application dowhole seismic source for crosswell imaging. now being investigated basis new concepts situ measurement rock properties including fractures.

Field measurements of the vibration amplitude a rotating-imbalance seismic source in liquid-filled borehole are described. The was cased oil well that had been characterized by gamma-ray cement bond and compensated neutron litho-density/gamma-ray logs. logs indicated an abrupt transition from shale to limestone at depth 2638 ft. frequency measured versus applied voltage as raised 2654 2618 ft through shale–limestone transition. It observed changed approximately 10% magnitude 15% passed were...
