This study will examine the feasibility and practicality of utilizing charcoal cloth in a light-weight solar powered distillation purification device incorporating charcoal cloth as the energy absorbent water wick. in this proposed device, it is expected that the charcoal cloth will act not only as… More

Research will be conducted into optical fiber-coupled fluorescent sensors for the continuous in vivo monitoring of blood gases. the purpose of phase i is to identify fluorescent chemical systems specifically sensitive to ph, po2, pco2, and temperature. from these identified systems, a selection will… More

This study will examine the feasibility and practicality of utilizing hydrogen peroxide or hydrogen peroxide compounds/solutions as a light weight, compact oxygen source for emergency breathing applications.

It is proposed that blood bags which have the capability to maintain stored blood in its fully oxygenated state will reduce red cell fragility and thereby will prolong the half-life of the red cell both during storage and following transfusion. this project will attempt to verify that maintaining… More

Quenching of room-temperature phosphorescence of luminescent compounds immobilized on or in suitable thin- film matrices is planned as a method for measuring relative humidity. combined with fiber optics technology this approach appears to have the capabilty of measuring relative humidity. combined… More

This proposal is to investigate the feasibility of utilizing luminescence quenching for measurement of relative humidity at temperatures found in arctic environments. it is based on the observation that certain fluorescent and phosphorescent compounds, immobilized on specific substrates, show a… More

The primary goal of this research is the development of an easily usable, nontraumatic apparatus for the accurate assessment of body volume in normal and low birth weight infants. a secondary goal is the inclusion of an assessmentof energy expenditure into the same apparatus. the method proposed for… More

The goal of this project is the development of a compact, low-cost expired breath analyzer suitable for diagnostic applications in hospital emergency rooms, clinics, and factory first aid stations. the first phase of this study will be a determination of the feasibility of developing a microvolume,… More

There is a clear need for an emergency oxygen delivery system that combines reliability, long-term storage capability, variable and controllable flow rate, small size,safety, and simplicity of use. of the available oxygen storage media, chemical systems offer a reasonable likeli- hood of achieving… More

The specific goal of this research is the development of a portable oxygen source suitable for use in providing supple-mental oxygen to individuals with chronic obstructive pulmonary disease (copd) resulting from chronic bronchioli- tis, pulmonary emphysema, asthma, or chronic bronchitis. the… More

The specific aim of this study is to design and evaluate theuse of hepa-filtered, laminar flow isolation systems as substitutes for present barrier systems in germ-free and gnotobiotic research using rodents and other small animals.

Phase i of this study will verify the feasibility of making substantial improvements in co(2) scrubber materials to allow safe and effective use under conditions of high metabolic energy expenditure producing co(2e exhalation rates in excess of 2 liters per minute. the feasibility study will examine… More

The primary objective of this proposed effort is to determine if a modified two-compartment ultrasonic vapor degreaser can be both an effective cleaner and an effective sterilant for frequently-used surgical instruments.

Efficient separation and purification of bioproducts on a commercial scale are controlling steps in the bioprocessing of high value-added products such as therapeutics in human health care. This project will examine the feasibility of achieving significant improvement in downstream processing… More
