Abstract—Gas flaring is one of the most GHG emitting sources in the oil and gas industries. It is also a major way for wasting such an energy that could be better utilized and even generates revenue. Minimize flaring is an effective approach for reducing GHG emissions and also conserving energy in flaring systems. Integrating waste and flared gases into the fuel gas networks (FGN) of refineries...

AIM To evaluate the effect of coronal flaring on the amount of debris extruded apically during root canal preparation using the Reciproc, WaveOne (WO) and OneShape (OS) single-file systems. METHODOLOGY Ninety extracted single-rooted mandibular incisor teeth were randomly assigned to six groups (n = 15 for each group) for canal instrumentation. Endodontic access cavities were prepared in each ...

We present results of an extensive investigation of the physical changes taking place in the emission regions of the LMXB X 1624-490 during strong flaring in observations made using RXTE in 1997 and 1999. Based on the detailed light curve, we propose that the flaring consists of a superposition of X-ray bursts. It is shown that major changes take place in the blackbody emission component, the t...

Reported here are primary avian geographical records for the nation of Peru and for the western declivity of the Peruvian Andes. Not previously encountered anywhere in Peru is Myrmeciza exsul (Chestnut-backed Antbird), a periorbitally blue thamnophilid possessing apically maculate tectrices. This species was observed on the western inclination of the Andean Mountains in Peru. Recorded primally ...

Abstract Here, we study the temperature structure of flaring and non-flaring coronal loops, using extracted loops from images taken in six extreme ultraviolet (EUV) channels recorded by Atmospheric Imaging Assembly (AIA)/ Solar Dynamic Observatory (SDO). We use data for X2.1-class-flaring active region (AR11283) during 22:10UT till 23:00UT, on 2011, September 6; (AR12194) 08:00:00UT 09:00:00UT ...

The uniqueness and stability of irradiated flaring passive protostellar disks is investigated in the context of a simplified set of equations for the vertical height H as a function of radius R. It is found that the well-known flaring disk solution with H ∝ R9/7 is not unique. Diverging solutions and asymptotically conical (H ∝ R) solutions are also found. Moreover, using time-dependent linear ...

A set of methods are presented for the global survey of natural gas flaring using data collected by the National Aeronautics and Space Administration/National Oceanic and Atmospheric Administration NASA/NOAA Visible Infrared Imaging Radiometer Suite (VIIRS). The accuracy of the flared gas volume estimates is rated at ̆9.5%. VIIRS is particularly well suited for detecting and measuring the radia...

BACKGROUND Long-pulsed Nd : YAG laser has been used in treating larger and deep-seated leg veins. OBJECTIVE This study investigated the effectiveness and safety of long-pulsed Nd : YAG laser to treat alae nasae and nasal tip telangiectasia. METHODS Twelve patients were evaluated in a prospective IRB approved study. They had a history of previous unsatisfactory treatments with pulsed dye las...
