Christensen, Douglas A. | Biosensor development at the University of Utah | Interest in biosensors has increased rapidly in the past few years due to the many potential advantages of these devices, such as small size, speed of response, and specificity 111. The term "biosensor" in the broad sense describes any device or apparatus which detects biological signals for the pu... | Silicon retina; Photosensing array; CHEMFET; Fluorescence lmmunosensor; Planar waveguide | 1994-07 |

Horch, Kenneth W. | On the number and nature of regenerating myelinated axons after lesions of cutaneous nerves in the cat | 1. Electrophysiological and anatomical techniques were used to investigate normal and regenerating sural and posterior femoral cutaneous nerve fibres in the cat. 2. One and a half years after transection of these nerves it was found that the regenerating neurones supported multiple sprouts in the... | Nerve fibres; Transection; Nerve injury | 1981 |

Horch, Kenneth W. | Ontogeny of diving and feeding behavior in juvenile seaturtles: Leatherback Seaturtles (Dermochelys coriacea L) and Green Seaturtles (Chelonia mydas L) in the Florida Current | We compared activity, diving behavior and response to prey by Dermochelys coriacea and Chelonia mydas during their first 8-10 weeks of development.We reared juveniles in the laboratory and, at two-week intervals, released them in the ocean for a brief trial. Each turtle towed a device used to measur... | Hatchlings; Posthatchling; Habitats | 2004 |

Christensen, Douglas A. | Interface of forest and agriculture in nonpoint pollution control | Management practices of agriculture, including conservation and tillage options, recently have received a great deal of attention with respect to their impact upon the environment. Research efforts have focused both on the direct impacts of reduced on-site productivity resulting from the erosion of ... | Suspended sediment; Channel erosion; Silviculture | 1983 |
