Dental impression is an important step in the preparation of prostheses since it provides the reproduction of anatomic and surface details of teeth and adjacent structures. The objective of this study was to evaluate the linear dimensional alterations in gypsum dies obtained with different elastomeric materials, using a resin coping impression technique with individual shells. A master cast mad...

groundwater is the sole source of accessible resource for agriculture in zeviercherry- kherran plains and water quality often falls in brackish group. in order to determine the source of salinity and hydrochemical processess affecting groundwater environment of the area, 61 groundwater samples were taken for hydrochemical analysis and composite diagrams (two variant diagrams of total concentrat...

In the indoor environment, people are exposed to several fungal species. Evident dampness is associated with increased respiratory symptoms. To examine the immune responses associated with fungal exposure, mice are often exposed to a single species grown on an agar medium. The aim of this study was to develop an inhalation exposure system to be able to examine responses in mice exposed to mixed...

It is demonstrated that an array of N dual-polarized antennas can cancel up to 2N-1 broadband interferers, while still maintaining a high probability of GPS satellite availability.

This note focuses on the coupling of a type IIA D2-brane to a background B field. It is shown that the D0-brane charge arising from the integral over the D2-brane of the pullback of the B field is cancelled by bulk contributions, for a compact D2-brane wrapping a homotopically trivial cycle in space-time. In M-theory this cancellation is a straightforward consequence of momentum conservation. T...

In this paper we construct generalised Penrose limits for the solutions of massive type IIA supergravity. We consider the Freund-Rubin type solution and apply these massive Penrose limits and obtain supersymmetric pp-wave which is standard type IIA background. The results in this paper can be easily generalised for the cases of gauged supergravities.

We present a supersymmetric action functional for the coupled system of an open fundamental superstring and super–D0–branes attached to (identified with) the string endpoints. As a preliminary step the geometrical actions for a free superD0-brane and a free type IIA superstring have been built. The pure bosonic limits of the action for the coupled system and of the equations of motion are discu...

We present an algorithm for learning a model of the effects of actions in noisy stochastic worlds. We consider learning in a 3D simulated blocks world with realistic physics. To model this world, we develop a planning representation with explicit mechanisms for expressing object reference and noise. We then present a learning algorithm that can create rules while also learning derived predicate...
