A novel mathematical model has been developed to aid the formulation of emulsion explosives. This mathematical model calculated heat of explosion, oxygen balance and raw material cost as a function of explosive ingredients, and the solution of the mathematical model was obtained by a MS Excel program. The effects of the different content of NH4NO3, NaNO3, H2O, and span-80 and composite fuel oil...

We study explosive synchronization, a phenomenon characterized by first-order phase transitions between incoherent and synchronized states in networks of coupled oscillators. While explosive synchronization has been the subject of many recent studies, in each case strong conditions on the heterogeneity of the network, its link weights, or its initial construction are imposed to engineer a first...

We propose an explanation for the recently observed powerful contained explosion in a Z pinch experiment performed at Sandia National Laboratories. Our arguments are based on the assumption that a pure SU(2) Yang-Mills theory of scale ∼ 0.5MeV is responsible for the emergence of the electron and its neutrino.

Explosive nucleosynthesis is a combination of the nuclear physics of thermonuclear reactions, and the hydrodynamics of the plasma in which the reactions occur. It depends upon the initial conditions—the stellar evolution up to the explosive instability, and the nature of the explosion mechanism. Some key issues for explosive nucleosynthesis are the interaction of burning with hydrodynamics, the...

Sir,?In the September issue, 1935, of your esteemed journal it has been mentioned, on page 506, by Dr. N. J. Vazifdar, that after a bomb explosion 'arsenic' enters into the system through the wound and also by inhalation of arsenuretted hydrogen which is evolved in the explosion. A bomb of the type under discussion explodes due to the interaction of sulphide of arsenic with an oxidizing agent s...

In this article, we examine variations in low-income mothers' patterns of intermittent cohabitation and the voluntary and involuntary nature of these unions. Intermittent cohabitation involves couples living together and separating in repeating cycles. Using Three-City Study ethnographic data, we identified 45 low-income mothers involved in these arrangements, 18 of whom resided with their chil...
