Four of nine exoplanets found by microlensing were detected by the resonant caustic, which represents the merging of the planetary and central caustics at the position when the projected separation of a host star and a bounded planet is s ∼ 1. One of the resonant caustic lensing events, OGLE-2005-BLG-169, was a caustic-crossing highmagnification event with Amax ∼ 800 and the source star was muc...

Abstract The technical and environmental aspects of treating electric arc furnace dust (EAFD) using a novel process including alkaline roasting organic acid leaching were evaluated compared to the globally applied conventional Waelz process. global warming potentials roasting–organic (with co-product credits) processes 7.48 4.71 kg CO 2 -eq with 33% Zn as feed material. However, decreasing cont...

Abstract Transmembrane flux measurements are the only practical tools used to evaluate degree of organic fouling and efficiency chemical cleaning ultrafiltration membranes in situ. Tangential pH-streaming potential profiles may become a comprehensive situ method analyse versus membrane damage. A parallel implementation two methods was assist tuning an efficient protocol for 300 kDa polyethersul...

This paper proposes a robust algorithm to compute caustics caused by multiple reflections and refractions on the GPU. The proposed algorithm solves two problems of previous methods, caustic light leaks and caustic undersampling. In order to eliminate caustic light leaks, terminal photon hits are stored and caustic patterns are reconstructed on the faces of a layered distance map attached to the...

this study was conducted to compare the yield and strength properties of soda and kraft pulp produced from populus deltoeides sapwood and heartwood. initially fiber length, lignin content in both sapwood and heartwood were measured. then from either sapwood or heartwood pulps were prepared with using soda and kraft processes, handsheets were made from this pulp and mechanical properties were me...

We describe the case of a 29-year-oldman who presented to the emergency room complaining of sudden and severe abdominal pain for 3 days. Evaluation on admission revealed low blood pressure, an increased heart rate, and tachypnea. Abdominal examination revealed a positive Blumberg sign and an abdominal radiograph showed pneumoperitoneum requiring urgent surgical evaluation. In the operating room...

Abstract In this work, the role of appropriate mixing for mercaptan removal from Kerosene using caustic soda has been investigated in the pilot scale. Static mixer at different condition has been used as a passive mixing tool to achieve proper mixing and consequently high performance of mercaptan removal. Two lengths of static mixer including 20 and 40 cm as well as two pitches 1 and 3 m...
