Electrolysis omission

An Error of Omission

We read with great interest a recent article entitled “Posterior Mediastinal Sarcoidosis” by Rosseel et al (Chest 1986; 90:462-64). As the authors indicate, posterior mediastmnal lymphadenopathy in sarcoidosis has rarely been recorded. It may be expected that frequent use of CT in these cases may change our current concept about the incidence of such involvement in the disease, and additional w...

Harm: Omission, Preemption, Freedom

CCA is an attractive account of harm. It has many virtues and many advantages over its competitors. But I won’t explore those features here. Ben Bradley gives a nice summary of them, though he ultimately rejects CCA (2012: 396–7, 401). In this paper, I’ll reply to two objections to CCA that haven’t been adequately addressed in the literature. Some critics think that certain omission and preempt...

Electrolysis-based diaphragm actuators.

This work presents a new electrolysis-based microelectromechanical systems (MEMS) diaphragm actuator. Electrolysis is a technique for converting electrical energy to pneumatic energy. Theoretically electrolysis can achieve a strain of 136 000% and is capable of generating a pressure above 200 MPa. Electrolysis actuators require modest electrical power and produce minimal heat. Due to the large ...

An omission in Special Relativity

In Special Relativity there are infinitely many equivalence classes of frames of reference. In each such class every two frames of reference move uniformly with respect to one another. It appears that the following questions have never been asked : In which of such equivalence classes of frames of reference is Special Relativity supposed to hold ? How can we identify such a class, and do so the...
