In thermodynamics, dissipation is the result of an irreversible process that affects a thermodynamic system.In a dissipative process, energy (internal, bulk flow kinetic, or system potential) transforms from an initial form to a final form, where the capacity of the final form to do thermodynamic work is less than that of the initial form.
Energy dissipation and entropy production extremal principles are ideas developed within non-equilibrium thermodynamics that attempt to predict the likely steady states and dynamical structures that a physical system might show. The search for extremum principles for non-equilibrium thermodynamics follows their successful use in other branches ...
The energy dispersal approach avoids the ambiguous term 'disorder'. An early advocate of the energy dispersal conception was Edward A. Guggenheim in 1949, using the word 'spread'. [1] [2] In this alternative approach, entropy is a measure of energy dispersal or spread at a specific temperature.
Munk & Wunsch (1998) estimated that Earth experiences 3.7 TW (0.0073 W/m 2) of tidal heating, of which 95% (3.5 TW or 0.0069 W/m 2) is associated with ocean tides and 5% (0.2 TW or 0.0004 W/m 2) is associated with Earth tides, with 3.2 TW being due to tidal interactions with the Moon and 0.5 TW being due to tidal interactions with the Sun. [3] Egbert & Ray (2001) confirmed that overall ...

There are several reasons why PIN is the most likely prostate cancer precursor. [3] PIN is more common in men with prostate cancer. High grade PIN can be found in 85 to 100% of radical prostatectomy specimens, [4] nearby or even in connection with prostate cancer. It tends to occur in the peripheral zone of the prostate.
PAP immunohistochemical staining is often used with PSA (staining), by pathologists, to help distinguish poorly differentiated carcinomas.For example, poorly differentiated prostate adenocarcinoma (prostate cancer) and urothelial carcinoma (bladder cancer) may appear similar under the microscope, but PAP and PSA staining can help differentiate them; [7] prostate adenocarcinoma often stains ...
Surgical removal of the prostate, or prostatectomy, is a common treatment either for early-stage prostate cancer or for cancer that has failed to respond to radiation therapy. The most common type is radical retropubic prostatectomy , when the surgeon removes the prostate through an abdominal incision.
