The purpose of this thesis is to consider Camus's use of the death metaphor and its probable meaning for him.
Death has been analysed in a heterogeneous way, according to the
theological, philosophical and scientific concepts of the world. Until
recently death was diagnosed following the cessation of the functions
of the heart and lungs. Currently, the ability to maintain cerebral
function with mechanical support, in the absence of spontaneous
breathing and heart beat, and the power to ensure circulation and
respiration, despite the complete destruction of the brain, demand a
redefinition of death. There is now the concept of brain death. In this
paper we discuss the concept of death, from ancient times to the modem
criteria for brain death. The historical definition will be discussed,
and the new criteria for diagnosing brain death will be explained.

John Donohue and Justin Wolfers argue that Gary Becker and Richard Posner are wrong to think that the death penalty deters murder: they find little empirical support for the claim. If anything, when one looks over the longest period possible (1934-2000) there is more evidence that the death penalty stimulates murder than that it deters murder.
Research about Maori children's experiences and perceptions of death and tangi (Maori death rituals) is sparse. What is available tends to be generalised and stems from Western paradigms of knowledge. In this study we explore Maori children's experiences of death and tangi through the eyes of Maori parents. Through semi-structured interviews with 17 Maori parents, five areas were explored: a) the childhood experiences of parents and how they learned about death and an afterlife; b) what their adult beliefs about these matters are; c) how they have communicated the death concept to their children; and d) whether their children are likely to do the same in the future. From this study we learn that death was not hidden from children, that parents talked with their children in very open and age relevant ways, and considered their children'...

Crib death remains poorly understood both morphologically and functionally. The cardiac hypotheses postulating that crib death is due to lethal cardiac electrical instability is gathering a renewed interest. Aim of this work is to examine the likely role of Mahaim fibers in relation to crib death. We analyze 72 autopsied cases of crib death (47 male and 26 female infants, ranging in age from 3 to 365 days) and 24 age-matched controls. Mahaim fibers were found in 21% of crib death and in 8% of control cases. Mahaim fibers are specialized accessory pathways connecting the atrio-ventricular junction and the upper ventricular septum. These fibers, under particular conditions and/or neurovegetative stimuli, may cause pre-excitation and potentially malignant arrhythmias. The whole atrio-ventricular system or its junctional tract, can become...
We demonstrate the difference between local, single-particle dynamics and global dynamics of entangled quantum systems coupled to independent environments. Using an all-optical experimental setup, we showed that, even when the environment-induced decay of each system is asymptotic, quantum entanglement may suddenly disappear. This "sudden death" constitutes yet another distinct and counterintuitive trait of entanglement.
