The efficacy of etidronate, a bisphosphonate, was assessed as a treatment for the inner ear symptoms of otosclerosis in a retrospective case review of 896 patients diagnosed with otosclerosis, with primary complaints of dizziness, hearing loss, tinnitus or Meniere's syndrome. The diagnosis of otosclerosis was based on smallpixel computed tomography of the temporal bones. Of the 896 patients pla...
assessment of the reservoir structure and determination of theinsitu stress direction arenecessary in oil production optimization andfield development. today, the application of reservoir software and image logsplay a central role in resolving this problem. electricand ultrasonic imaging tools record vast amounts of high-resolution data within the borehole wall. this enables the geoscientists t...

To assess whether Helicobacter pylon-related inflammation increases oxidative DNA damage, we evaluated the association between H. pylon infection and urinary excretion of an adduct of oxidative DNA damage, 8-hydroxy-2-deoxyguanosine (8ohdG). Subjects included 555 healthy persons, ages 20-39, within the Kaiser Permanente Medical Care Program in Northern California. We tested sera for antibodies ...
چین جناغی یک نوع خاص از چین خوردگی هاست که در طبقه بندی هندسی چین ها قرار داده می شوند. نمونه ای از این نوع چین ها در ناودیس جناغی تنگ ماغر، واقع در یال جنوبی تاقدیس کوه بنگستان، در شمال بهبهان و در استان خوزستان دیده شده است. این ناودیس جناغی در کمربند ساده چین خورده زاگرس واقع شده است و رخنمون اصلی آن را سازند سروک تشکیل می دهد. برداشت-های صحرایی انجام شده و انتقال آنها به استریونت و تحلیل اس...

This line has a concentration of oleic acid in the seed oil that is approximately 550 g kg. This is between 340 and 380 g kg greater than commercial soybean varieties and 47 g kg more than the...
We performed an integrated study of multistage hydraulic fracture stimulation of two parallel horizontal wells in the Bakken Formation in the Williston Basin, North Dakota. There are three distinct parts of this study: development of a geomechanical model for the study area, interpretation of multiarray downhole recordings of microseismic events, and interpretation of hydraulic fracturing data ...
