101 Jarrard, Richard D.Resistivity/porosity/velocity relationships from downhole logs: an aid for evaluating pore morphologyRelationships between downhole resistivity/velocity logs and porosity styles, controlled by cementation/dissolution/recrystallization, are investigated using core and downhole logging data from the carbonate-rich sediments encountered during Leg 133 of the Ocean Drilling Program (ODP), northeastern ...1993
102 Dailey, Andrew T.Resolution of an actinomycotic abscess with nonsurgical treatment: case reportA CASE OF actinomycotic brain abscess is presented. Conservative treatment by prolonged administration of antibiotics after needle biopsy showed complete resolution of the abscess. Previously reported cases suggest that definitive treatment requires excision or open surgical drainage of the abscess...Actinomycotic abscess; Brain abscess; Actinomyces israelii; Nonsurgical treatment1993
103 Bruderlin, BeatRobust solid modeling by avoiding redundancy for manifold objects in boundary representationThis paper describes a new approach to the robustness problem in solid modeling. We identify as t h e main cause of t h e lack of robustness that interdependent topological relations are derived from approximate data. Disregarding the interdependencies very likely violates basic properties, such as...Robust solid modeling; Manifold objects; Boundary representation; Robustness problem1993
104 Kriesel, John D.; Spruance, Spotswood L.Rocky Mountain spotted fever following cardiac transplantation.ROCKY MOUNTAIN SPOTTED FEVER was first recognized in the early 1 900s in the Snake River Valley of Idaho and the Bitterroot Valley of western Montana.t In 1909, Howard Taylor Ricketts established the ixodid tick as the vector for the disease.2 Following the tick bite, the incubation period aver...Male; Adult; Humans1993
105 Kestle, John R. W.Role of angiography following aneurysm surgeryThe postoperative angiograms in 66 patients who underwent craniotomy for clipping of 78 cerebral aneurysms were reviewed. Indications for urgent postoperative angiography included neurological deficit or repeat subarachnoid hemorrhage. Routine postoperative angiograms were carried out in the remai...Postoperative angiography; Aneurysm rest; Cerebral angiography; Vascular occlusion1993
106 Schmidt, Meic H.Role of photodynamic therapy in posterior fossa brain tumors: a preclinical study in a canine glioma modelPhotodynamic therapy was studied in dogs with and without posterior fossa glioblastomas. This mode of therapy consisted of intravenous administration of Photofrin-II at doses ranging from 0.75 to 4 mg/kg 24 hours prior to laser light irradiation in the posterior fossa. Tissue levels of Photofrin-l...Brain neoplasm; Posterior fossa; Photodynamic therapy; Glioblastomas; Dog; Photofrin-II; Canine glioma model1993
107 Miller, Jan D.; Lin, Chen-LuhScientific visualization in mineral and material processingScientific visualization is an ideal methodology for investigating complex phenomena that are characterized by large amounts of data. Furthermore, it is invaluable in the study of processes that evolve in time. Scientific visualization relies heavily on computer graphics, image processing and video...Air sparged hydrocyclone flotation; Ball mill grinding; Tomography; Computer graphics1993
108 Jarrard, Richard D.Sedimentology and downhole log analysis of Site 820, central Great Barrier Reef outer shelf: the factors controlling Pleistocene progradational and aggradational seismic geometryThe textural and compositional characteristics of the 400 m sequence of Pleistocene wackestones and packstones intersected at Ocean Drilling Program (ODP) Site 820 reflect deposition controlled by fluctuations in sea-level, and by variations in the rate of sediment supply. The development of an effe...1993
109 Ehleringer, James R.Seedling size and survival for Chrysothamnus nauseosusSeedling size and survival in relation to summer drought were examined for Chrysothamnus nauseosus growing under field and greenhouse conditions. In the field, summer survival rates were less than 2% annually for the three years monitored. The effect of initial seedling height on subsequent survival...Chrysothamnus nauseosus; Seedling size; Seedling survival1993
110 Horch, Kenneth W.Selective activation of functional muscle groups through stimulation of spinal motor poolsA microelectrode was used to stimulate motor neurons in the lumbo-sacral spinal cord of adult cats. Consistent with spinal cord anatomical studies, we found that the motor neurons responsible for activation of individual muscle groups are situated together in specific areas of the cord, forming mot...Spinal motor pools1993
111 Horch, Kenneth W.Selective stimulation of peripheral nerve fibers using dual intrafascicular electrodesWe have studied activation of newe fibers by pairs of Pt-Ir wire electrodes implanted within single fascicles of the nerve innervating the gastrocnemius muscle in cats. The purpose of this study was to determine if these intrafascicular electrodes can activate nerve fibers in different fascicles...Functional electrical stimulation; Intrafascicular stimulation; Silicon electrode array1993

113 Battin, Margaret P.Seven (more) caveats concerning the discussion of euthanasia in the NetherlandsDiscussion in the U.S. about euthanasia in the Netherlands is characterized by profound disagreement, both about what the practice actually is and what risks it involves. Some time ago, I put together a little list1 of seven warnings for bioethicists embroiled in this discussion-things one ought to...1993

115 McDaniel, SusanSingle parenthood: policy apartheid in CanadaPolicy discussions regarding single parents often move to income maintenance issues. While the risk of poverty for single mothers with dependent children is high, attention devoted largely to the policy challenges of income maintenance for single mothers may have two unfortunate consequences. Firs...Single mothers; Social policy; Canada1993
116 Miller, Jan D.Solvent extraction reagents for gold recovery from alkaline cyanide solutionsThree different solvent extraction systems for the recovery of gold from alkaline cyanide solutions are reviewed. These include the modified amine extractants in which the basicity of simple alkyl amines, with respect to the aurocyanide anion, is controlled by the addition of alkyl phosphorous ester...Solvents; Extraction; Gold; Alkaline cyanide; Amine extractants; Solvating extractants; Substituted guanidines1993
117 Gopalakrishnan, GaneshSome unusual micropipeline circuitsWe present a few unusual Micropipelines (Sutherland, CACM, September 1989) that employ the Muller C-ELEMENT or an extension of the C-ELEMENT called LOCKC (Liebchen and Gopalakrishnan, ICCD, 1992). We first describe two variations of the two-dimensional Micropipeline structure realized using ordinary...Micropipeline circuits; Micropipelines1993
118 Morse, Michael DavidSpectroscopic analysis of jet-cooled AICuDiatomic AlCu has been interrogated using resonant two-photon ionization spectroscopy in a supersonic expansion of helium. The ground state is shown to be X l?+, deriving from the 3&3dgd configuration, in agreement with theoretical predictions. The closed-shell nature of this molecule results in a l...1993
119 Morse, Michael DavidSpectroscopic studies of jet-cooled AINiResonant two-photon ionization spectroscopy has been used to interrogate diatomic AlNi produced by laser vaporization of a 1:l alloy target in a supersonic molecular beam of helium.

125 Battin, Margaret P.Suicidology and the right to dieAs suicidology reflects on the issue of the right to die, it can make no bigger mistake than by seeing suicide and suicidal behavior in short-sighted isolation, without reference to the cultural context within which it occurs. Two kinds of myopia currently afflict us in particularly constricting way...1993
