The Second Law of Thermodynamics and the Heart
Future Cardiology, 2012The second law of thermodynamics explains the phenomenon of irreversibility and the increasing entropic trend of nature. Similar to human-made machines, living structures are subjected to entropy generation, becoming 'worn' and 'damaged' from use. However, they have the possibility of eluding or deferring these processes.

GRAVITATION AND THE SECOND LAW OF THERMODYNAMICS
International Journal of Modern Physics D, 2004Just as gravitons can carry energy, they can also be used to transmit information. It follows that an entropy should be associated with gravitational degrees of freedom, independent of the presence or absence of black holes. In this essay, we discuss how one might count gravitational entropy given a classical gravitational field.

Though the balance of entropy has been denoted as Second Law of Thermodynamics in the previous chapters, its classical formulation comes along with thermodynamic cycles. Thus, the focus now is on these cycles. However, there are two different types of thermodynamic cycles: Clockwise cycles on the one hand convert heat into mechanical energy and are ...

Life and the Second Law of Thermodynamics
Nature, 1946WHETHER life processes obey the second law of thermodynamics or if life finds a way of evading the otherwise universal dissipation of energy has been something of a puzzle for a century. Kelvin left the matter open in his formulation of the Second Law, by expressly excluding the operations of ‘animate agencies’.

The second law of thermodynamics
1991The first law of thermodynamics was developed in Chapter 4 from a study of the effects of adiabatic work on the state of a system. This law introduces the concept of internal energy (a non-primitive state function) and imposes certain limitations on the changes that can occur in a system under given constraints.

The Second Law of Thermodynamics
2018Abstract The Second Law. The definition of entropy, and its mathematical properties. The Clausius inequality, and the criterion of spontaneity of change in an isolated system. Worked examples of heat flow down a temperature gradient, and the adiabatic expansion of a gas into a vacuum.

The Second Law of Thermodynamics
The Journal of Chemical Physics, 1961Derivations of the mathematical statement of the second law of thermodynamics from the physical statements of Kelvin and Clausius are presented. Caratheodory's principle is obtained as a direct consequence of either Kelvin's or Clausius's statement.

Nature, 1973
IT is widely realised that there is no single and uniquely correct statement of the Second Law of Thermodynamics but rather that there exist a number of different and mutually compatible, correct statements1 (Everett2 mentions “two or three dozen”) each of which illuminates a different facet of what H. A.
