THE PROPOSED WORK IS TO DEVELOP HIGHLY CHARGED, ULTRAFILTRATION MEMBRANES BY THE CHEMICAL GRAFTING APPROACH FOR THE PARTIAL DEMINERALIZATION OF SALINE GROUNDWATERS FOR IRRIGATION PURPOSES. THE KEY TO ACHIEVING THIS OBJECTIVE IS TO DETERMINE WHAT INITIATOR-MONOMER-CATALYST-SOLVENT CHEMICAL SYSTEMS CAN ACHIEVE THE HIGH MEMBRANE CHARGE DENSITIES NECESSARY FOR THE ENHANCED REJECTION OF MULTIVALENT ION ...

METHODS FOR RELIABLE ASSESSING THE STRENGTH OF WOOD COMPOSITES WILL BE DEVELOPED USING NONDESTRUCTIVE EVALUATION PROCEDURES INVOLVING SPECTRAL ANALYSIS OF STRESSWAVE PARAMETERS. THESE PROCEDURES ARE BASED ON THE EXTENSION OF PREVIOUS RESEARCH ON NONDESTRUCTIVE EVALUATION OF THE STRENGTH OF WOOD UTILITY POLES. THEY APPEAR TO OFFER CONSIDERABLE PROMISE AS RELIABLE STRENGTH PREDICTION METHODS FOR OTH ...

RECOGNIZING SERIOUS CONSTRAINTS ASSOCIATED WITH PRESENT M METHODS OF EXPORT MOVEMENT OF FOOD STAPLES SUCH AS WHEAT FLOUR TO DEVELOPING COUNTRIES, THE RESEARCHER PROPOSES A CONTAINERIZED SYSTEM. THE CONCEPT ELIMINATES THE USE OF BAGSAND SUBSTITUTES SELF DISCHARGING SEALED CONTAINERS WITH SPECIALIZED VESSELS. THE PROPOSED SYSTEM WOULD PERMIT MOVEMENT OF PRODUCTS FROM THE U.S. PRODUCING POINT TO FORE ...

THE LOCATION OF HUMAN GEOGRAPHICAL BOUNDARIES CURRENTLY PRO PROVIDES ON OF THE BASES IN SEVERAL U.S. FOREST SERVICE REGIONS, FOR INSTANCE, FOR RESOLVING SOCIAL/CULTURAL ISSUES AND PROBLEMS RELATED TO THE DEVELOPMENT OF RURAL AREAS. THISPROJECT WILL ATTEMPT TO DETERMINE A MORE EFFICIENT YET RELIABLE METHOD FOR DESCRIBING HUMAN GEOGRAPHICAL BOUNDARIESUSING QUANTITATIVE METHODS. HUMAN GEOGRAPHICAL BO ...

N/A

SOIL CONTAMINATION BY TOXIC WASTES HAS DESTROYED SIGNIFICANTVALUABLE LAND ACREAGE. RECENT DEVELOPMENT OF SOIL REMEDIATION TECHNOLOGIES PERMITS RECLAMATION OF MUCH LOST LAND FOR PRODUCTIVE USES. THE PROPOSED RESEARCH WILL INVESTIGATE REVEGETATION METHODS WHICH WILL COMPLETE THE SOIL DETOXIFICATION PROCESS AND PERMANENTLY STABILIZE THE RECLAIMED SOIL. UNDER PHASE I, GREENHOUSE TESTS WILL BE CONDUCTE ...

A NEW TECHNIQUE WILL BE DEVELOPED FOR THE RAPID FREEZING OF BOVINE EMBRYOS IN LATE MORULA STAGE. THE APPROACH IS BASED ON THE FACT THAT EACH EMBRYO IS A DEVELOPING SYSTEM WHOSE RESPONSE TO FREEZING IS UNIQUE. THE PROPOSED METHOD QUANT ITATIVELY ASSESSES THE STATE OF DEVELOPMENT FOR EACH EMBRYO AND FORMULATES AN OPTIMUM FREEZING PROTOCOL FOR THAT EMBRYO. NO PENETRATING CRYOPROTECTANT IS EMPLOYED AN ...

THE PROPOSED FEASIBILITY RESEARCH IS TO USE A UNIQUE GRAFTI ING TECHNIQUE TO MODIFY MEMBRANE MATERIALS IN SUCH A WAY AS TO RENDER THEM USEFUL FOR SPECIFIC WATER TREATMENT SITUATIONS. THE WORK WILL SPECIFICALLY FOCUS ON THE DEVELOP MENT OF THE GRAFTING TECHNIQUE FOR POROUS MEMBRANE MATERIAL S. THE TECHNIQUE WILL BE DEMONSTRATED BY THE GRAFTING OF CHARGED MONOMER AND POLYMERS ONTO SEVERAL MATERIALS ...

WE PROPOSE TO EXPLOIT DUAL ENERGY X-RAY MEASUREMENT TECH- NIQUE TO QUANTITATIVELY DETERMINE THE PRO PORTIONS OF TWO DIFFERENT MATERIALS IN A FOOD PROCESSING LINE AT CONVEYOR BELT SPEED. THE MAIN PROBLEM WITH A SIMPLECONVENTIONAL X-RAY INSPECTION SYSTEM IS THAT IT REQUIRES KNOWN MATERIAL THICKNESS BETWEEN THE X-RAY SOURCE AND DETEC-TOR ARRAY. OFTEN IT IS VERY DIFFICULT TO OBTAIN KNOWN OR DEFINITIVE ...
