Burning Rates of Solid Propellants
The Journal of Chemical Physics, 1960The burning mechanism of a solid propellant is described in terms of a pyrolysis law, a premixed laminar flame, and nothing more. A quantitatively accurate burning rate formula is derived from the theory. The predicted burning rate pressure dependence agrees with the experimental results for ammonium perchlorate propellants.

Carborane Burning Rate Catalysts
1972Abstract : New carborane burning rate accelerators designed for use in solid propellants, without the problems associated with current accelerators, have been prepared. High molecular weight, non-volatile derivatives of bis(1- carboranylmethyl) and bis-(1-carboranylethyl) ethers were synthesized and evaluated for compatibility in HTPB binders as well ...

Improvement in catheter sepsis rate in burned children
Journal of Pediatric Surgery, 1990Routine frequent central venous catheter (CVC) changes in burned patients (either change in insertion site or change over guidewires) has been advocated to decrease catheter-related sepsis. The need for this management has not been verified for children with burns.

Reduction of the mortality rate in aged burn patients
Burns, 1992The management of elderly burn patients is time consuming for both nursing staff and physicians, and therapy remains often challenging and controversial. In a retrospective study, we analysed the outcome of two periods with different treatment modalities. An increased number of nurses, a change in the local burn wound treatment, better documentation of

Rate of Healing in Skin-Grafted Burn Wounds
Plastic and Reconstructive Surgery, 2007Skin grafting is a simple and common procedure for achieving wound closure. Despite its widespread use, there is little objective information about the outcomes of skin-grafted burn wounds. The purposes of this study were to determine the length of time it takes to achieve complete wound healing in split-thickness skin-grafted burn wounds and to ...

Heat Release Rates of Burning Items in Fires
Journal of Propulsion and Power, 2000Heat release rates of typical items in fires are needed as a prerequisite for estimating fire growth and temperatures in structural fires. That is, these burning rates, in terms of heat release rate vs time, are required to be specified by the user as input to single-room and multiroom structural fire computer codes such as CFAST, FASTLite, FPETool ...

Review of composite propellant burn rate modeling
17th Aerospace Sciences Meeting, 1979Steady-state combustion modeling of composite solid propellants is discussed with emphasis on the Beckstead-Derr-Price (BDP) model. The BDP model and some revisions are considered with respect to the analysis of monomodal ammonium perchlorate/inert binder propellants: topics examined include continuity relations, surface area relations, characteristic ...

ELECTROCHEMICAL BURN RATE ACCELERATION
International Journal of Energetic Materials and Chemical PropulsionAn electrochemical mechanism of accelerating the burn rate of pyrotechnic compositions and composite propellants is presented. Magnesium-Teflon-graphite fluoride-graphite (MTGFG) compositions were used as the model system to demonstrate the effect. Electric currents are generated in situ by electrochemical cell reactions in the composition itself by ...

Socioeconomic factors and burn rates in persons hospitalized for burns in Massachusetts.
Public health reports (Washington, D.C. : 1974), 1986To assess the usefulness of routinely collected socioeconomic variables from the U.S. census in predicting burn incidence rates, burn rates and 25 socioeconomic variables were analyzed at the level of census tracts for the Boston Standard Metropolitan Statistical Area.
