New Reducible Membrane Solutions in D = 11

چکیده
We construct generalized 11D supergravity solutions of fully localized D2/D6 brane intersections. These solutions are obtained by embedding Taub-NUT and/or self-dual geometries lifted to M-theory. We reduce these solutions to ten dimensions, obtaining new D-brane systems in type IIA supergravity. We discuss the limits in which the dynamics of the D2 brane decouples from the bulk for these solutions.

متن کاملOverlapping Branes in M -Theory
We construct new supersymmetric solutions of D=11 supergravity describing n orthogonally “overlapping” membranes and fivebranes for n=2,. . . ,8. Overlapping branes arise after separating intersecting branes in a direction transverse to all of the branes. The solutions, which generalize known intersecting brane solutions, preserve at least 2−n of the supersymmetry. Each pairwise overlap involve...
متن کاملA Study on Neodymium Recovery from Aqueous Solutions for Designing a New Generation of Sandwich Liquid Membrane
Liquid Membrane (LM) based processes, as Supported Liquid Membranes (SLMs), have been proposed, for over 30 years, as effective methods for the selective separation of inorganic/organic species from different water streams. The industrial use of SLMs has been limited mainly by their insufcient stability. To investigate on the main cause of system destabilization and the o...
متن کاملThe effect of Dendrostellera lessertii on the cell membrane redistribution of alkalinee phosphatase
Several mammalian enzymes are anchored to the outer surface of plasma membrane by a covalently attached glycosyl-phosphatidylinisitol (GPI) structure. These include acetylcholinesterase, alkalinee phosphatase and 5´-nucleotidase. Recently, it has been reported that these membrane enzymes can be solubilized into the serum by GPI-dependent PLD, under various medical disturbances such as cancer an...
