Misoprostol and attempted self-induction of abortion [PDF]
Journal of the Royal Society of Medicine, 1998 Sporadic reports have documented the use in countries such as Brazil and Mozambique of misoprostol to self-induce pregnancy termination (PT). This paper presents the case of a young woman from Mozambique who presented to a UK surgery requesting PT .

Self-inductance coefficient for toroidal thin conductors [PDF]
Nonlinear Analysis: Theory, Methods & Applications, 2001 We consider the inductance coefficient for a thin toroidal inductor whose thickness depends on a small parameter " > 0. An explicit form of the singular part of the corresponding potential u " is given. This allows to construct the limit potential u (as " → 0) and an approximation of the inductance coefficientL " .

Improved Formulae for the Inductance of Straight Wires
Advanced Electromagnetics, 2014 The best analytical formulae for the self-inductance of rectangular coils of circular cross section available in the literature were derived from formulae for the partial inductance of straight wires, which, in turn, are based on the well-known formula ...

One Hundred and Fifty Years of Skin Effect
Applied Sciences, 2023 In 1873, J.C. Maxwell derived relations for current density and current in a solitary long cylindrical conductor supplied with variable current. According to Maxwell, the current density in a conductor increases towards the conductor surface.

Self inductance of a wire loop as a curve integral
Advanced Electromagnetics, 2016 It is shown that the self inductance of a wire loop can be written as a curve integral akin to the Neumann formula for the mutual inductance of two wire loops. The only difference is that contributions where the two integration variables get too close to

On Simplified Calculations of Leakage Inductances of Power Transformers
Energies, 2020 This paper deals with the problem of the leakage inductance calculations in power transformers. Commonly, the leakage flux in the air zone is represented by short-circuit inductance, which determines the short-circuit voltage, which is a very important ...
