Window-of-Opportunity for In Situ Burning

Ventriculoatrial (VA) shunts are a method of cerebrospinal fluid diversion, which nowadays are infrequently seen in medical practice. Infective endocarditis (IE) can occur as rare complications of VA shunts, through the introduction of a foreign body close to the tricuspid valve. We report a case of infective endocarditis, that is, in a patient with VA shunt for congenital hydrocephalus. We present the case to highlight the importance of early investigation for IE in patients with fever of unknown origin and shunt in situ, as rapid deterioration can occur and be fatal. We also discuss past experience reported in the literature on the role of cardiothoracic intervention. Prompt diagnosis and early cardiothoracic referral for surgery are crucial, there may only be a narrow window of opportunity for intervention before patients develop fulminant sepsis.

Outside The Box

ABSTRACT A spill in May 1997, forced responders to think “outside the box” and utilize ingenuity and skills learned from previous experiences. The Region VI RRT Guidelines for In-shore/Near-shore In Situ Burn, while providing the framework for the plan, had to be modified on site to meet the special parameters this spill presented.Responders had not had previous opportunities to burn this type of environment and were not sure what type of successes to expect.The initial burn was to be conducted well outside of what is normally considered the window of opportunity for in situ burning.PM-10 monitors were to be utilized to monitor smoke plume fallout particle size.It was determined by the Federal On-Scene Coordinator (FOSC) that RRT approval was not necessary and deferred to the consensus among state agencies having jurisdiction. This response indicates inland/nearshore burns will continue to be utilized as a response tool and points to the need for ongoing evaluations and adjustments to pre-approvals and guidance documents responders utilize.

ABSTRACT A laboratory test program was conducted with six crude oils to determine the following parameters with respect to in situ burning:The limits to ignition using gelled-gasoline igniters imposed by evaporation and emulsion-formationThe ability of commercially-available emulsion breakers and alternative fuel igniters to extend the window-of-opportunity for ignition of stable emulsionsThe effects of wave action on the combustion of emulsion slicks,The likelihood of the residues sinking after efficient burns of thick slicks of the crude oils As well as providing valuable spill-response oriented data, the study has shown that in situ burning may not be an appropriate response option for all oils. Some oils were easily ignited and burned efficiently, even when emulsified to high water contents. One oil could not be ignited even when fresh. The ability of emulsion breakers to promote emulsion ignition and burning was found to be oil-dependent.

Saturn's Rings

ABSTRACTA mission to rendezvous with the rings of Saturn is studied with regard to science rationale and instrumentation and engineering feasibility and design. Future detailedin situexploration of the rings of Saturn will require spacecraft systems with enormous propulsive capability. NASA is currently studying the critical technologies for just such a system, called Nuclear Electric Propulsion (NEP). Electric propulsion is the only technology which can effectively provide the required total impulse for this demanding mission. Furthermore, the power source must be nuclear because the solar energy reaching Saturn is only 1% of that at the Earth. An important aspect of this mission is the ability of the low thrust propulsion system to continuously boost the spacecraft above the ring plane as it spirals in toward Saturn, thus enabling scientific measurements of ring particles from only a few kilometers.
