This paper reports on an ultrasonic measurement system and its application for in situ real-time measurement of very fast regression rates (>200 mm/s) of the melting interface (RRMI) produced when burning particular metals such as aluminium at high pressures. The RRMI is referred to as the rate at which a solid/liquid interface moves along a metallic rod while burning in an oxygen-enriched atmo...

In order to understand the combustion properties of crude oi I pool fires. an experimental study was done in Fire Research lnstitute(FRI) large scale test faci I ity. The radiative output, burning rate, and the concentrations of CO, CO 2 , and smoke (above the flame tip) were measured during the burn­ ing of Arabian I ight crude oi I. Several different size tanks were used to study the scale ef...

We have studied the sensitivity to variations in the the triple alpha and C(α, γ)O reaction rates of the production of Al, Ti, and Fe in core-collapse supernovae. We used the KEPLER code to model the evolution of 15M⊙, 20M⊙, and 25M⊙ stars to the onset of core collapse and simulated the ensuing supernova explosion using a piston model for the explosion. Calculations were performed for the Ander...

Composite solid propellants were prepared with and without nano-alloys (Ti-Co, Ti-Ni, Ti-Zn), where nano-alloys used as catalyst. These nano-alloys are prepared by hydrazine reduction method. Catalytic properties of these nanomaterials were measured on Ammonium perchorate/hydroxyterminatedpolybutadiene propellant by thermogravimetery analysis and differential thermal analysis. Both experimental...

The 187 suicide occurring in the city of Jhansi, over a period of two years (1986-87), gave an annual incidence rate of 29 per lakh population. The rate was higher for females (34 per lakh) than for males (24 per lakh). The commonest age group was the third decade (51.3%), followed by the second (28.4%); the average age of males being significantly higher. The married committed suicide more oft...

The methanol-burning lung model has been used as a technique for generating a predictable ratio of carbon dioxide production (VCO2) to oxygen consumption (VO2) or respiratory quotient (RQ). Although an accurate RQ can be generated, quantitatively predictable and adjustable VO2 and VCO2 cannot be generated. We describe a new burner device in which the combustion rate of methanol is always equal ...
