  2. Deposition (phase transition) - Wikipedia

    en.wikipedia.org/wiki/Deposition_(phase_transition)

    Deposition is the phase transition in which gas transforms into solid without passing through the liquid phase. Deposition is a thermodynamic process . The reverse of deposition is sublimation and hence sometimes deposition is called desublimation .

  3. Deposition (aerosol physics) - Wikipedia

    en.wikipedia.org/wiki/Deposition_(aerosol_physics)

    In the physics of aerosols, deposition is the process by which aerosol particles collect or deposit themselves on solid surfaces, decreasing the concentration of the particles in the air. It can be divided into two sub-processes: dry and wet deposition. The rate of deposition, or the deposition velocity, is slowest for particles of an ...

    en.wikipedia.org/wiki/Back-of-the-envelope...

    A back-of-the-envelope calculation is a rough calculation, typically jotted down on any available scrap of paper such as an envelope.It is more than a guess but less than an accurate calculation or mathematical proof.

    The program was renamed to National Talent Search Scheme with the NTSE examination now being conducted for classes X, XI, and XII. Currently, the NTSE exam is conducted only for 10th class students in India in two phases with subjects relating to Mental Ability Test and Scholastic Aptitude Test (SAT) for 100 marks each.

  6. On shell and off shell - Wikipedia

    en.wikipedia.org/wiki/On_shell_and_off_shell

    An example comes from considering a scalar field in D-dimensional Minkowski space.Consider a Lagrangian density given by (,).The action is = (,). The Euler–Lagrange equation for this action can be found by varying the field and its derivative and setting the variation to zero, and is:

  7. Particle deposition - Wikipedia

    en.wikipedia.org/wiki/Particle_deposition

    Particle deposition is the spontaneous attachment of particles to surfaces. The particles in question are normally colloidal particles , while the surfaces involved may be planar, curved, or may represent particles much larger in size than the depositing ones (e.g., sand grains).

  8. Magnetohydrodynamics - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamics

    In physics and engineering, magnetohydrodynamics (MHD; also called magneto-fluid dynamics or hydro­magnetics) is a model of electrically conducting fluids that treats all interpenetrating particle species together as a single continuous medium.

  9. Kardar–Parisi–Zhang equation - Wikipedia

    en.wikipedia.org/wiki/Kardar–Parisi–Zhang...

    Via the renormalization group, the KPZ equation is conjectured to be the field theory of many surface growth models, such as the Eden model, ballistic deposition, and the weakly asymmetric single step solid on solid process (SOS) model. A rigorous proof has been given by Bertini and Giacomin in the case of the SOS model.
