A bstract Background When the nasal obstruction is identified in cases of snoring and/or OSA with suspected oropharyngeal and obstruction, combination palate surgeries suggested to be conducted either a single-staged or multi-staged manner. This study aimed assess efficacy safety combined nasal-palatopharyngeal surgery staged versus single-stage multilevel procedure. Methods Prospective randomi...

BACKGROUND Approximately a fifth of all total hip arthroplasty (THA) patients suffers from bilateral osteoarthritis of the hip. It is unclear whether mortality risks differ between simultaneous bilateral THA and staged bilateral THA. We investigated mortality after simultaneous THA compared with staged bilateral THA in the largest cohort hitherto reported. METHODS The 42,238 patients reported...

This work seeks virtual constraints, or outputs, that are intrinsic to human walking and utilises these outputs to construct controllers which produce human-like bipedal robotic walking. Beginning with experimental human walking data, human outputs are sought, i.e., functions of the kinematics of the human over time, which provides a low-dimensional representation of human walking. It will be s...

BACKGROUND We examined the effects of wear time on a population profile of time-stamped accelerometer outputs using the 2005-2006 National Health and Nutrition Examination Survey (NHANES) data representing 3744 adults ≥ 20 years of age. METHODS Outputs included activity counts, steps, and time variables: nonwear (macro-determined), sedentary behavior (<100 activity counts/minute), and time in...

abstract one of the techniques that has been used in different areas of sciences, and probably would be able to simulate complicated process of rainfall-run off is artificial neural network (ann). the purpose of this research is to evaluate the applicability of ann in rainfall- run off simulation and the comparison of the results to those produced by hec-hms model in azam river basin of herat i...

Recently, ammonia is emerging as a potential source of energy in power generation and industrial sectors. One the main concerns with combustion large amount NO emission. Air staging conventional method reducing emission which similar to Rich-Burn, Quick-Mix, Lean-Burn (RQL) concept. In air-staged combustion, major reduction based on near zero at fuel-rich NH3/Air mixture. A secondary air stream...

Oscillating levels of clock gene transcripts in the suprachiasmatic nucleus (SCN) are essential components of the mammalian circadian pacemaker. Their synchronization with daily light cycles involves neural connections from light-sensitive photoreceptor-containing retinal ganglion cells. This clock orchestrates rhythmic expression for approximately 10% of the SCN gene transcripts, of which only...
