Abstract: The present invention is directed to a method for removing elemental mercury from liquid natural gas comprising changing the stabilizer column operating conditions to beneficially transfer mercury from the stabilized condensate phase to the overhead gas phase, where it may be compressed and recycled with the gas going to the existing feed gas mercury removal units.

Abstract: A broadband tuning system includes a first chip and a second chip. The first chip includes a first light amplification region, a first forward grating region and a first backward grating region that are sequentially arranged in a first direction. The first light amplification region is configured to amplify a first light source and to turn on or turn off the first light source, and the first forward grating region and the first backward grating region are configured to tune the first light source. The second chip includes a second light amplification region, a second forward grating region and a second backward grating region that are sequentially arranged in a second direction. The second light amplification region is configured to amplify a second light source and to turn on or turn off the second light source, and the second forward grating region and the second backward grating region are configured to tune the second light source.

Abstract: Embodiments of the present invention relate to the field of communications technologies, and provide a method for controlling a screen of a mobile terminal, and an apparatus, to resolve a prior-art problem of relatively low accuracy of controlling a screen of a mobile terminal to be turned on or turned off. The method includes: obtaining, by a mobile terminal, a current motion parameter of the mobile terminal, and determining whether the motion parameter meets a pick-up parameter threshold or a put-down parameter threshold; when the motion parameter meets the pick-up parameter threshold, determining that the mobile terminal is picked up; obtaining a sight line parameter of a user; and when it is determined that a visual center of the user is on a screen of the mobile terminal and the screen is in an off state, switching the screen to an on state.

Abstract: A process of making a reinforced hollow fiber membrane comprises flowing a membrane dope through a casting head while drawing one or more yarns or tows of filaments through the casting head. The filaments are spread apart in the casting head, for example by forcing the yarns or tows around a bend or through a narrow gap in the casting head. The filaments are adapted to bond to the membrane dope or the membrane wall. A reinforced hollow fiber membrane comprises a plurality of filaments individually surrounded by, and bonded to, the membrane wall.

Abstract: A filtration membrane for micro- or ultra-filtration is formed from a complex of PVDF and calcined .alpha.-alumina (".alpha.-Al") particles, in which complex the particles are reacted and dispersed. The suspended complex is then mixed with a hydrophilic polymer such as polyvinyl alcohol (40%-90% hydrolyzed) referred to herein as HPVA, which reacts with the complex imparting hydrophilicity to the polymer. The novel membrane provides about 50% higher specific flux than a membrane made with the same polymer but without the .alpha.-Al particles. Unexpectedly, the net flux is improved by treating the membrane with a solution of sodium hypochlorite which fails to remove the HPVA from the novel membrane but does remove it from the prior art membrane which does not contain the .alpha.-Al. The preferred membrane comprises a macroporous support coated on its outer surface with a thin tubular asymmetric semipermeable film of polymer containing less than about 50% by weight of .alpha.-Al particles.
