My proceeds by arguing facts about given agent's quality will can play different explanatory role in larger theory blameworthiness and structure exculpation than is often assumed.

The potential of using Cf-252 to treat cancer patients was first described by Shlea and Stoddard in 1965 as a source of neutrons using brachytherapy procedures [Stoddard, 1986]. In the late 1960’s and early 1970’s, the United States and England initiated human clinical trials of Cf-252 neutron brachytherapy (NBT) for treating patients of various cancer types. These earlier trials treated only v...

Monte Carlo Method is used to simulate a double layer gadolinium-amorphous silicon thermal neutron detector. The detector fabricated in pixel array configuration has various applications including neutron imaging. According to the simulation results, a detector consisting of a gadolinium (Gd) film with thickness of 2-4 ~m, sandwiched properly with two layers of sufficiently thick (-30 ?µm) hydr...

It is a common fear in many countries that ideological parties will come to power through elections but will implement extreme policies. Many countries cope with this problem by overriding the election results when such parties are elected. We demonstrate that the alternative approach of containing these parties within the democratic system is more effective. We show that, as the probability of...
