THERE IS A NEED TO MANAGE BETTER THE INPUT OF POLLUTANTS WHICH ADVERSELY AFFECT THE AQUATIC ENVIRONMENT. ALTHOUGH MANAGEMENT PRACTICES CURRENTLY USED HAVE PROVIDED INFORMATION ON TOXICITY POTENTIAL THROUGH THE USE OF BIOASSAYS DONE ON DISCRETE SAMPLES, MORE VALUABLE INFORMATION WOULD BE AVAILABLE FOR MANAGEMENT DECISIONS IF CONTINUOUS REAL-TIME BIOMONITORING WERE EMPLOYED. THE MAJOROBJECTIVES OF T ...

A LARGE DEPLETION OF ATMOSPHERIC OZONE IS OCCURRING EACH AUSTRAL SPRING OVER ANTARCTICA. REFERRED TO AS THE OZONE HOLE PROBLEM, THE CONCERN IS THAT OZONE-POOR AIR FROM THE ANTARCTIC STRATOSPHERE IS MIXING WITH AIR AT LOWER LATITUDES. FURTHERMORE, THERE ARE INDICATIONS THAT THE SIZE OF THE HOLE COULD INCREASE AND WILL CONTINUE TO FORM FOR THE NEXT 90 YEARS EVEN IF CFC RELEASES ARE CONTROLLED. SUCH ...

A THEORETICAL PROGRAM IS PROPOSED TO INVESTIGATE A COMPACT, LOW-VOLTAGE INFRARED GRATING LASER WITH MULTI-KILOWATT OUPUT CAPABILITY. THE RADIATION IS GENERATED BY THE PASSAGE OF AN ANNULAR BEAM OF ELECTRONS THROUGH A COAXIAL PAIR OF CONDUCTORS, THE INNER CONDUCTOR BEING A CORRUGATED CYLINDER WHICH FORMS THE GRATING. THE ELECTRON BEAM IS GUIDED BY AN AXIAL MAGNETIC FIELD. THE DIMENSIONS OF THE OPTI ...

This receiver sets forth a plan to utilize commercial GPS receivers for real time ionospheric prediction at a remote location. The project will demonstrate the feasibility of using TEC measurements and evaluate the accuracy and applicability of these measurements for improvements in HF propagation. For this we assess the predictability of the slab thickness parameter T towards solar and geophysica ...

This proposal sets forth a plan to analyze and archive ionosonde data. Large amounts of ionosonde data have been collected and are still being collected in analog form. We propose to design and develop a scanner which will accept these analog data, interpret them and finally archive the ionospheric information in a systematic manner. During Phase I, we develop the algorithm for ionogram interpreta ...

Beta thalassemia, the most common disease inherited at a single genetic locus, is a major cause of morbidity and mortality in populations having high frequencies of the beta-thalassemia mutations. At this juncture, the mainstays of therapy in afflicted populations consist of population screening, genetic counseling, and prenatal diagnosis. Accurate diagnosis, on which each of these depends, entail ...
