Abstract Flat lakes with a large catchment area are especially affected by sediment inputs. The Kolleru Lake (south-eastern India) surface of approximately 6121 km 2 belongs to such types lake basins. study’s main objective was the assessment both soil erosion and yield concentration rate catchment. study conducted using revised universal loss equation (RUSLE) model due its simple good applicab...

An approximate analytic solution is constructed for the 2D space-charge-limited emission by a cathode surrounded by nonemitting conducting ledges of width Lambda. An essentially exact solution (via conformal mapping) of the electrostatic problem in vacuum is matched to the solution of a linearized problem in the space charge region whose boundaries are sharp due to the presence of a strong magn...

We present a novel design of optical micro-cavity where the optical energy resides primarily in free space, therefore is readily accessible to foreign objects such as atoms, molecules, mechanical resonators, etc. We describe the physics of these resonators, and propose a design method based on stochastic optimization. Cavity designs with diffraction-limited mode volumes and quality factors in t...

We show that complete conformally flat manifolds of dimension n > 3 with nonnegative Ricci curvature enjoy nice rigidity properties: they are either flat, or locally isometric to a product of a sphere and a line, or are globally conformally equivalent to R n or a spherical spaceform Sn/Γ. This extends previous results due to Q.-M. Cheng and B.-L. Chen and X.-P. Zhu. In this note, we study compl...

We present multiwaveband observations of a well-selected sample of 28 quasars and two radio galaxies with Ñat radio spectra and strong millimeter-wave emission (referred to here as FSRQs). The data are analyzed to determine the radio to infrared and X-ray to c-ray properties of FSRQs and the relationships between them. SpeciÐcally, the synchrotron self-Compton (SSC) process is examined as a lik...
