Electron energy distribution functions (EEDF’s) are presented over a two-dimensional array of locations in the discharge chamber of a 40-cm diameter ring-cusp ion thruster. The EEDF’s are obtained using two different techniques illustrating comparable results. A distinct difference in the EEDF’s measured through the double layer potential gradient, which transitions between the low-potential di...

Dorsal hump reduction can create both functional and aesthetic problems if performed incorrectly. Component dorsal hump reduction allows a graduated approach to the correction of the nasal dorsum by emphasizing the integrity of the upper lateral cartilages when performing dorsal reduction. Use of this approach can minimize the need for spreader grafts in primary rhinoplasty patients. Possible u...

In rail freight operation, freight cars need to be separated and reformed into new trains at hump yards. The classification procedure is complex and hump yards constitute bottlenecks in the rail freight network, often causing outbound trains to be delayed. One of the problems is that planning for the allocation of tracks at hump yards is difficult, given that the planner has limited resources (...

We calculate the spectral energy distribution (SED) of electromagnetic radiation and the spectrum of high energy neutrinos from BL Lac objects in the context of the Synchrotron Proton Blazar Model. In this model, the high energy hump of the SED is due to accelerated protons, while most of the low energy hump is due to synchrotron radiation by co-accelerated electrons. To accelerate protons to s...

BACKGROUND Some patients with Perthes disease develop abnormal gait in the transverse plane, that is, out-toeing or in-toeing. Considering that this phenomenon occurs mainly in patients who presented late without previous treatment or failed in the containment treatment, we postulated that the deformed femoral head and its impingement to the acetabulum may play an important role in the pathomec...

INTRODUCTION The availability of raltegravir plus atazanavir provides an alternative antiretroviral strategy that may be equally efficacious and less toxic than those currently recommended in HIV treatment guidelines. In fact, this new combination antiretroviral therapy attracts the attention of the scientific community because both drugs have a good safety profile coupled with potent antiviral...

BACKGROUND Alterations in the spinal column and obesity are on the rise, causing great concern in health and educational strata. This paper aims to take a step further and study in detail the relationship of the presence of scoliotic hump in obese schoolchildren. OBJECTIVE was to determine the relationship between prevalence of types of variables hump and sociodemographic, anthropometric, and...

OBJECTIVES Traditionally, scoliosis surgery is aimed at attaining a fused, balanced and painless spine. With improvement in surgical and instrumentation techniques, spine surgeons strive to achieve higher degree of Cobb's angle and rib hump correction with the idea of greater patient satisfaction. The aim of this study was to determine the patients' satisfaction using SRS-22 questionnaire and t...
