Self-Cannibalism: The Man Who Eats Himself
Self-mutilation is a general term for a variety of forms of intentional self-harm without the wish to die. Although there have been many reports of self-mutilation injuries in the literature, none have reported self-cannibalism after self-mutilation. In this article we present a patient with self-cannibalism following self-mutilation. A 34-year-old male patient was brought to the emergency depa...
متن کاملMales Can Benefit from Sexual Cannibalism Facilitated by Self-Sacrifice
In a number of species, males are cannibalized by females after mating (reviewed in [1, 2]), and some males actually appear to facilitate their own cannibalism (reviewed in [3]). Such self-sacrifice can evolve if being eaten sufficiently enhances either fertilization success (mating effort) or offspring number or fitness (paternal effort). While there is some support for the mating-effort hypot...

متن کاملSelf-regulated Accretion Disks
We consider a class of fully self-gravitating accretion disks, for which efficient cooling mechanisms are assumed to maintain the disk close to the margin of Jeans instability. For such self-regulated disks the equations become very simple in the outer regions, where the angular momentum convective transport approximately balances the viscous transport. These latter equations are shown to lead ...
