AIR TOXIC METALS AND THEIR COMPOUNDS ARE PRODUCED FROM THE COMBUSTION OF FOSSIL-FUELS. THE COMBUSTION OF COAL AND FUEL OIL REPRESENTS AN EXTREMELY LARGE CATEGORY OF SOURCE EMISSIONS. RESEARCH IS PROPOSED THAT WILL PROVIDE A MEANS FOR REMOVING THE VOLATILE METAL CONTENT OF FLUE GAS GENERATED FROM POWER AND STEAM GENERATING PLANTS USING ZEOLITIC OR CARBONACEOUS ADSORBENTS. A LABORATORY-SCALE FIXTURE ...

THE PROPOSED RESEARCH FOCUSES ON A STUDY OF THE FEASIBILITY AND EFFECTIVENESS OF AUGMENTING A COMPUTER-BASED INSTRUCT- IONAL PACKAGE IN ENGLISH COMPOSITION FOR ADULT LITERACY STUDENTS WITH AUDIO SUPPORT. THIS AUGMENTATION IS MADE POSSIBLE THROUGH THE USE OF A UNIQUE COMPUTER-INTERFACABLE AUDIOTAPE TECHNOLOGY DEVELOPED BY MEMBERS OF THE PROPOSED PROJECT TEAM UNDER ANOTHER FEDERAL CONTRACT. THIS TEC ...

ION EXCHANGE IS AN ATTRACTIVE TECHNOLOGY FOR REMOVAL OF HEAVY METALS FROM WATER AND WASTEWATERS, BUT IT IS COMMONLY FOUND TO BE UNECONOMICAL DUE TO THE HIGH COST OF CHEMICALS AND DISPOSAL OF THE BRINES OR SECONDARY WASTES GENERATED. SEVERAL IMPROVEMENTS TO THIS TECHNOLOGY ARE PROPOSED TO ALLOW ION EXCHANGE TO BE MORE WIDELY APPLIED TO THE REMOVAL OF TOXIC HEAVY METALS AT SUPERFUND SITES AND IN OTH ...

THIS PROJECT IS FOCUSED ON THE CREATION OF A DATA RECEPTION, STORAGE, AND DISPLAY DEVICE WHICH WOULD BE LINKEDWITH A COURT REPORTER'S STENOGRAPH (VIA A TRANSLATION SOFTWARE PACKAGE, COUPLED TO A DATA PACKETIZATION AND TRANSMISSION DEVICE) TO ALLOW THE HEARING IMPAIRED TO CLOSELY FOLLOW AND UNDERSTAND COURTROOM AURAL PROCEEDINGS. ADVANCED CONCEPTS IN DIGITAL COMMUNICATIONS AND INNOVATIVE SOFTWARE A ...

THE FLUOROCARBON INDUSTRY IN THE UNITED STATES CURRENTLY GENERATES OVER 1,200,000 POUNDS OF SPENT ANTIMONY FLUOROCARBON CATALYST ANNUALLY IN PRODUCING 1,190 MILLION POUNDS OF FLUOROCARBONS (CFCS, HCFCS, HFCS). THIS SPENT CATALYST IS A MIXTURE OF HALOGENATED ORGANIC COMPOUNDS (HOCS), ANTIMONY, AND ARSENIC HALIDES. IT IS EXTREMELY HAZARDOUS, TOXIC, AND CORROSIVE. IT CONTAINS AT LEAST EIGHT LISTED "C ...

SUCCESSFUL DRINKING WATER PURIFICATION REQUIRES PROPER COAGULATION, USUALLY WITH ALUM, FOR REMOVAL OF DISEASE TRANSMITTING ORGANISMS. THE GROWING NATIONAL NEED FOR IMPROVED PERFORMANCE OF PURIFICATION INVOLVING COAGULATION-FILTRATION COULD BEST BE HELPED BY USE OF AN AUTOMATED COAGULANT DOSE CONTROL INSTRUMENT. THE BEST TECHNOLOGY AVAILABLE NOW IS STREAMING CURRENT DETECTORS. THEIR MAJOR SHORTCOMI ...

THE INDIVIDUALS WITH DISABLILTIES EDUCATION ACT REQUIRES TRANSITION PLANNING, RELATED INSTRUCTION AND INTERAGENCY COORDINATION FOR ALL SPECIAL EDUCATION STUDENTS. THE MOVEMENT FROM SCHOOL TO POST-SCHOOL ACTIVITIES IS AN IMPORTANT EVENT IN TERMS OF THE INFORMATION WHICH CAN BE CAPTURED AND ANALYZED. SPECIFICALLY, THE EMPLOYMENT HISTORY OF DISABLED INDIVIDUALS HAS BEEN A CONCERN NOTED IN A NUMBER OF ...

SAFE, COST EFFECTIVE ALTERNATIVES TO CHLORINE TREATMENT OF DRINKING WATER FOR DISTRIBUTION AND DISINFECTION HAVE BEEN SOUGHT FOR SOME TIME. CHLORINE DIOXIDE IS A VIABLE ALTERNATIVE TO CHLORINE FOR THE TREATMENT OF EVEN POOR QUALITY WATER SUPPLIES AND THE REDUCTION OF POTENTIAL CANCER CAUSING CHLORINATED ORGANICS. ITS WIDESPREAD USE HAS BEEN INHIBITED BY THE COSTS AND/OR COMPLEXITY OF ITS PRODUCTIO ...

THERE ARE NUMEROUS INDUSTRIAL PROCESSES REQUIRING THAT MATERIAL BE HEATED AND THEN SUBSEQUENTLY COOLED. IF MOST OF THIS HEAT IS RECOVERED AND RECYCLED TO THE OVEN, THE NET POWER INPUT TO THE OVEN COULD BE SUBSTANTIALLY REDUCED. THE KEY TO ACCOMPLISHING THIS IS AN INCREASE OF THE HEAT TRANSFER COEFFICIENT BETWEEN GAS AND MATERIAL SO THAT THE HEAT EXCHANGERS ARE RESASONABLY COMPACT. SIMPLE EXPERIMEN ...
