Murine ovarian tumors produced by polycyclic aromatic hydro carbons like benzo(a)pyrene (BP) require small cocyte destruc tion. Small oocyte destruction was evaluated in C57BL/6N (B6), DBA/2N (D2), and C57BL/6J x DBA/2J F, (B6D2F,) mice follow ing intraovarian injection with BP, (+H7fl,8S)-ox¡de, (-)-{7R,BR)dihydrodiol [(-)-DHD], or (+)-(7fl,8S)-diol-(9S,10ri)-epoxide-2 [(+)-DE2] at doses rang...

We consider the interaction of two enemy nations. Nation 1 wants to develop a nuclear bomb (or other weapons of mass destruction). Nation 2 wants to prevent such a development through the deterrence of a threatened attack, or an actual attack if it thought the bomb was produced. 2 has an intelligence system that imperfectly indicates the presence of a bomb. 1, if lacking the bomb, can open its ...

Navigating a Concept Lattice Family w.r.t a Query Introduction Relational Concept Analysis (RCA) constructs conceptual abstractions from a relational context family (RCF). An RCF is sets of objects described by both own properties and inter-object links. It generates several lattices that are connected via relational attributes. Navigating such interrelated lattice family in order to find conce...

This article reviews the Report on the U.S. Intelligence Community’s Prewar Intelligence Assessments on Iraq, Senate Select Committee on Intelligence, 7 July 2004, Review of Intelligence on Weapons of Mass Destruction, a Report ...

The large load and poor heat dissipation of moon rock core drilling leads to the difficulty breaking low sampling efficiency. As a new auxiliary method, laser is expected be applied perturbation in lunar drilling. Revealing fracture characteristics mechanism under irradiation an important basis for realizing laser-assisted sampling. Basalt was used as simulated sample, its mechanical response w...
