TL;DR: In this article, the preparation and characterization of polysulfone (PSf)/β-cyclodextrin (β-CD) composite membranes using a modified phase inversion technique was presented.
91 citations
TL;DR: In this paper, the response surface methodology (RSM) based on central composite design (CCD) was successfully applied to the optimization of the Safranin removal process, and the results revealed that the adsorption process was spontaneous and endothermic.

TL;DR: In this article, the effect of influential parameters which posses embarking affect on the adsorption process such as contact time, temperature and initial concentration of methylene blue (MB) dye in solution were well investigated and elucidated.

TL;DR: In this paper, the physics potential of multi-megaton scale ice or water Cherenkov detectors with low (~ 1 GeV) threshold is explored, and the significance of the measurements of the neutrino parameters and the dependence of this significance on the accuracy of reconstruction of the Neutrino energy and direction is explored.
Abstract: We explore the physics potential of multi-megaton scale ice or water Cherenkov detectors with low (~ 1 GeV) threshold. Using some proposed characteristics of the PINGU detector setup we compute the distributions of events versus neutrino energy E
ν and zenith angle θz , and study their dependence on yet unknown neutrino parameters. The (E
ν − θz) regions are identified where the distributions have the highest sensitivity to the neutrino mass hierarchy, to the deviation of the 2-3 mixing from the maximal one and to the CP-phase. We evaluate significance of the measurements of the neutrino parameters and explore dependence of this significance on the accuracy of reconstruction of the neutrino energy and direction. The effect of degeneracy of the parameters on the sensitivities is also discussed. We estimate the characteristics of future detectors (energy and angle resolution, volume, etc.) required for establishing the neutrino mass hierarchy with high confidence level. We find that the hierarchy can be identified at 3σ-10σ level (depending on the reconstruction accuracies) after 5 years of PINGU operation.

TL;DR: In this article, the authors analyzed ancient atmospheric gases trapped in fluid inclusions contained in minerals of Archean (3.3 Ga) to Paleozoic (404 Ma) rocks in an attempt to document the evolution of the elemental composition and isotopic signature of the atmosphere with time.
