Analysis of the Impact of Managed Pressure Drilling Technology on Current Casing Program Design Methods (TECHNICAL NOTE)

This paper analyzed the characteristics of managed pressure drilling (MPD) technology and impact of wellhead back pressure on the wellbore annulus pressure profile, and found that the application of this technology provides room for improvement to the current casing program design. Meanwhile, the equivalent density of drilling fluid in wellbore annulus needs to consider the impact of back press...

Symmetric Hadron Pairs at Large Transverse Momenta as a Test of Hard Scattering Models

The inclusive cross section of hadron pairs produced back-to-back with large transverse momenta is examined in the parton model. It is shown quantitatively that this cross section is determined directly by the hard scattering subprocesses, without being influenced by the internal momentum of the constituents, even for transverse momenta of the order of 2-3 GeV/c. The predictions of the phenomen...

Probing the Top-Quark Electric Dipole Moment at a Photon Linear Collider

We probe the top-quark electric dipole moment (EDM) in top-quark pair production via photon-photon fusion at a photon linear collider. We show how linearly-polarized photon beams can be used to extract information on the topquark EDM without the use of complicated angular correlations of top-quark decay products. If the luminosity of the laser back-scattered photon-photon collisions is comparab...

Effect of 8-Week Core Stabilization Exercises on Low Back Pain, Abdominal and Back Muscle Endurance in Patients with Chronic Low Back Pain due to Disc Herniation

Purpose: The aim of this study was to investigate the effect of core stabilization exercises on low back pain and abdominal and back muscle endurance in patients with chronic low back pain caused by disc herniation. Methods: For this purpose, 30 male and female patients with chronic low back pain due to disc herniation (age =48.55 ± 3.35) were divided into experimental and control groups (...
