 | Biotechnology, in general terms, is the science and engineering of using living organisms for making useful products such as pharmaceuticals, foods, fuels, chemicals, materials or in waste treatment processes and clinical and chemical analyses. It encompasses the prosaic form of using yeast cells to make bread and alcohol to the more exciting world of using recombinant DNA technology for producing critically important pharmaceuticals such as human insulin. However, the use ... |

|
| The objective of this project was to design and operate a bench-scale biological treatment system capable of degrading trichlorethylene (TCE) and benzene, each present at concentrations up to 50 ppm, to concentrations of 4 ppb or less per contaminant. A two-stage reactor system was designed and fabricated to allow for the sequential degradation of benzene followed by TCE since TCE demonstrated no inhibitory effects on benzene degradation. A first-stage fixed- ... |

|
| An investigation was conducted to evaluate the influence of area-of- interest (AOI) display characteristics on target detection performance and head movements. Two AOI display conditions were compared: a small (26.44 by 21.51 deg horizontal and vertical), higher resolution AOI and a large (40.00 by 30.00 deg horizontal and vertical), lower resolution AOI. The observers viewed a computer- generated visual scene consisting of three-dimensional cylinder-shaped objects placed upright on a desert ... |

| This report describes the development of both incoherent and coherent fiber optic sensors for monitoring the electrical activity of cells and tissue. The incoherent sensors use an optical fiber to deliver laser light to a cell membrane that is stained with a voltage-sensitive dye. The change in resulting fluorescence allows the electrical activity of the cell to be monitored. The coherent fiber sensor uses an external element, either a cell ... |

| The report presents a simple algorithm for machine visual target detection and localization based on aspects of the known functional neuroanatomy of biological systems. The system can generate, from the relative motion of a target image on the sensor surface, a series of motor commands that reorient the high-resolution portion of the sensor surface to regions of the target that potentially contain the most information. The reorientations are analogous to ... |

| Bioremediation is an innovative technology being considered more frequently, and more positively, for the remediation of soil contaminated with organic compounds. The main advantages of soil bioremediation are that it can be done on site (possibly avoiding land disposal restrictions) at relatively low cost and involves destruction of contaminants without transferring them to another media. While many points discussed will be applicable to soil bioremediation in general, the Tech Data ... |

| The direct assessment of heat flux from the body is a basic measurement in thermal physiology. Heat flux transducers (HFTs) are being used increasingly for that purpose under different environmental conditions. However, questions have been raised regarding the accuracy of the manufacturer's constant of calibration, and also about the effect of the thermal resistance of the device on the true thermal flux from the skin. Two different types of waterproofed ... |

| The air-bubble detection systems was designed to detect the changes in the microwave absorption properties of tissues--these changes could be caused by the introduction of air bubbles due to exposure to high altitudes. The system basically transmits a low-level modulated microwave signal through the tissue and monitors the changes in the amplitude of the received signal. The output signal from the detection circuitry can be monitored using an oscilloscope or ... |
