The Preparation Of In Vivo Lead X-Ray Fluorescence System Using 99mtc, Yusoff Mohd Amin, R.H. Mahat, W.M. Loon

Research Publications (2000 to 2005)

99mTc is widely used in hospital for nuc1ear medical examination such as scintigraphy of brain and thyroid. The gamma energy emitted by the 99mTc (140.50 keY) is used to produce X-ray fluorescence of the lead atoms present in bones. Being an internal source it is expected the fluorescence efficiency to increase. Using a surface barrier X-ray detection system, we have found the minimum detectable concentration (MDC), of lead in bone phantom, is 500 ppm using K-edge X-ray. The bone phantom consists of 10 ml polythene test-tube filled with saline solution and sodium (99mTc) pertechnetate of activity ranging from 7.4 III …

Psychologie Jenseits Postmoderner Kritik, Kenneth J. Gergen

Psychology Faculty Works

Postmodernes Denken formuliert wichtige Einwände gegenüber Vorstellungen von individuellem Wissen, Objektivität und Wahrheit. Statt ihrer wird die gemeinschaftliche (communal) Konstruktion von Wissen betont, liegt der Schwerpunkt auf Objektivität als einer intersubjektiven (relational) Errungenschaft und auf Sprache als einem pragmatischen Medium, das lokale Wahrheiten hervorbringt. Diese Entwicklungen bedeuten nicht notwendigerweise das Ende wissenschaftlicher Psychologie. Vielmehr laden sie dazu ein, eine Reihe neuer Fragen in Hinblick auf die Möglichkeiten traditioneller Forschung und ihrer Bedeutung im kulturellen Leben zu stellen. Wichtiger noch: Eine solche Kritik eröffnet neuartige, theoretisch, methodologisch und praktisch bedeutsame Perspektiven. Anzeichen einer solchen Ausrichtung häufen sich, was zeigt, dass grundlegende …

Supreme Court Voting Behavior 2004 Term, Richard G. Wilkins, Scott Worthington, Jacob Reynolds, John J. Nielsen

UC Law Constitutional Quarterly

The 2004 Term, for the third straight year, notes a liberal trend on the Court. The outcomes tabulated on six of ten Tables in 2004, considered as a whole, manifest overall liberal movement. These results strengthen the hypothesis posed by last year's study that "the United States Supreme Court may have embarked on a new course." The stability of any such trend, however, may depend upon the voting behaviors of the two positions on the Court opened at the end of the 2005 Term. Chief Justice Rehnquist, statistically speaking, was the most conservative Member of the Court this Term as …

Short-Term Impacts Of Military Overflights On Caribou During Calving Season, James P. Lawler, Audrey J. Magoun, C. Tom Seaton, Craig L. Gardner, Rodney D. Boertje, Jay M. Ver Hoef, Patricia A. Del Vecchio

United States National Park Service: Publications

The Fortymile Caribou Herd (FCH) is the most prominent caribou herd in interior Alaska. A large portion of the FCH calving and summer range lies beneath heavily used Military Operations Areas (MOA) that are important for flight training. We observed the behavior of Grant’s cow caribou (Rangifer tarandus granti) and their calves before, during, and immediately following low-level military jet overflights. We also monitored movements of radiocollared cow caribou and survival of their calves. We conducted fieldwork from mid May through early June 2002. We concluded that military jet overflights did not cause deaths of caribou calves in …

Validation Of A Modern Aviation Psychology Test Battery Using Aertificial Neural Networks: First Results Of Two Pilot Studies, Markus Sommer, Dr. G. Schuhfried Gmbh

International Symposium on Aviation Psychology - 2005

The present paper deals with the problem of data integration in the context of aviation psychological assessment. In the first pilot study 99 pilot applicants completed a comprehensive test battery. The general judgment of the candidates’ performance in a flight simulator served as an external criterion. To examine the predictive validity of this test battery, both a discriminant analysis as well as an artificial neural network were calculated and compared with each other with regard to classification rate, stability, and their respective differentiability of suited and not suited applicants based on their success probabilities. The results of this first pilot …

The "Best K" For Entropy-Based Categorical Data Clustering, Keke Chen, Ling Liu

Kno.e.sis Publications

With the growing demand on cluster analysis for categorical data, a handful of categorical clustering algorithms have been developed. Surprisingly, to our knowledge, none has satisfactorily addressed the important problem for categorical clustering – how can we determine the best K number of clusters for a categorical dataset? Since categorical data does not have the inherent distance function as the similarity measure, traditional cluster validation techniques based on the geometry shape and density distribution cannot be applied to answer this question. In this paper, we investigate the entropy property of the categorical data and propose a BkPlot method for determining …

C And C+ In The Venusian Thermosphere/Ionosphere, Jane L. Fox, L. J. Paxton

Physics Faculty Publications

We have constructed standard low and high solar activity models of the Venus thermosphere, which take into account revised rate coefficients for production and loss processes for C and C⁺, high-resolution cross sections for photodissociation of CO, and recent solar fluxes from the Solar 2000 v1.24 and v2.22 models of Tobiska [2004]. Among the most important changes is the inclusion of the branching ratio for the channel of dissociative recombination of CO₂⁺ that produces C + O₂, which has been measured recently by Seiersen et al. [2003]. We find that unlike Mars, where the …

Thermospheric Distribution Of Fast O(D-1) Atoms, V. Kharchenko, A. Dalgarno, Jane L. Fox

Physics Faculty Publications

Detailed calculations are carried out of the sources of energetic metastable O(¹D) atoms in the atmosphere at altitudes between 80 km and 200 km, and the corresponding energy distribution functions are derived, taking account of energy transfer and quenching in collisions of the metastable atoms with the ambient atmospheric gas constituents. The energy relaxation of metastable oxygen atoms produced by O₂ and O₃ photolysis and O₂ ⁺ dissociative recombination is determined by solving the time-dependent Boltzmann equation. The O(¹D) thermalization and quenching times are obtained as functions of the altitude. The steady state …

Effects Of Dissociative Recombination On The Composition Of Planetary Atmospheres, Jane L. Fox

Physics Faculty Publications

Because dissociative recombination (DR) reactions of molecular ions are often highly exothermic, in the thermospheres of the Earth and planets DR may be a source of translationally and internally excited fragments. DR is important, therefore, for thermospheric neutral heating; if the excited fragments radiate to space, however, DR may be also a source of thermospheric cooling. DR may produce metastable fragments, which may live long enough to participate in reactions that are not available to ground state species. It is rare, however, for DR to be a significant source of minor species in their ground states. An exception appears to …

Ion Cyclotron Waves In The Saturnian Magnetosphere Associated With Cassini's Engine Exhaust, C. T. Russell, J. S. Leisner, K. K. Khurana, M. K. Dougherty, X. Blanco-Cano, Jane L. Fox

Physics Faculty Publications

Five hours after the orbit insertion maneuver that placed Cassini into orbit about Saturn, a long (90 minute) burst of ion cyclotron waves were seen, very different than any waves on the inbound leg of the orbit or on succeeding orbits. The ion cyclotron waves were left-hand elliptically polarized and propagating at a moderately large angle to the local magnetic field. The waves had a noticeable compressional component consistent with their off angle propagation. The frequency band of the signals was moderately broad and consistent with the singly ionized components of the engine exhaust gases: CO₂, N_{2 …}

Toric Residue And Combinatorial Degree, Ivan Soprunov

Mathematics and Statistics Faculty Publications

Consider an -dimensional projective toric variety defined by a convex lattice polytope . David Cox introduced the toric residue map given by a collection of divisors on . In the case when the are -invariant divisors whose sum is , the toric residue map is the multiplication by an integer number. We show that this number is the degree of a certain map from the boundary of the polytope to the boundary of a simplex. This degree can be computed combinatorially. We also study radical monomial ideals of the homogeneous coordinate ring of . We give a necessary and sufficient …

Compromising Liberty: A Structural Critique Of The Sentencing Guidelines, Jackie Gardina

University of Michigan Journal of Law Reform

This Article contends that the federal sentencing guidelines-whether mandatory or discretionary-violate the constitutional separation of powers by impermissibly interfering with a criminal jury's constitutional duty to act as a check against government overreaching. This Article posits that the inclusion of the criminal jury in Article III of the Constitution was intended as an inseparable element of the constitutional system of checks and balances. This Article also submits a proposal for restoring the constitutional balance through the creation of a "guideline jury system" within the current guideline structure. The implementation of a guideline jury system would fill the constitutional void created …

Discordant Harmonies In Fingernail Clam Populations (Musculium Transversum) Of Mississippi River Backwater Lakes, Jim Eckblad

Journal of the Iowa Academy of Science: JIAS

The populations of Musculium transversum from 8 backwater lakes have been studied over a 29-year period based upon over 440 grab samples. These lakes in Navigation Pool 9 of the Upper Mississippi River (UMR) range in size from 2 to 255 hectare surface area, mean depths from 0.2 to 0.9 meters, with mean water exchange times from 0.5 to almost 57 hours. Samples from the 1989-91 period suggested summer Muscu!ium populations had declined to about 9 percent of their mid-1970 levels. Deterministic models have attempted to explain this decline. More recent sampling suggests a substantial recovery of Musculium populations (mid-summer …

Threatened By Industry, Saved By Science: Mussel Propagation At The Fairport Biological Laboratory, James Pritchard

Journal of the Iowa Academy of Science: JIAS

During the 1890s, people on the Mississippi River exploited mussel populations to support a thriving button industry. Within a brief time, they noticed significant declines in mussel populations, and called on the U.S. Bureau of Fisheries to save the resource. This paper discusses mussel propagation studies, techniques, and activities carried on in association with the Fairport Biological Laboratory (Iowa) from about 1908 to 1932. While scientists developed sophisticated techniques and had success in mussel propagation, changing habitat conditions in the river (caused mainly by pollution and dam construction) meant limited success in rescuing mussel stocks, while the introduction of plastic …

Sedimentological Characteristics And Internal Architecture Of Two Overwash Fans From Hurricanes Ivan And Jeanne, Mark H. Horwitz, Ping Wang

Geology Faculty Publications

Extensive overwash occurred along the Florida coast during the passage of four strong hurricanes in 2004, providing an excellent opportunity to study the spatial patterns and sedimentary architecture of washover deposits. Detailed 3D sedimentological characteristics of two of the overwash fans were studied through coring, trenching, and ground penetration radar surveys. The first washover-fan complex, deposited by hurricanes Frances and Jeanne is located on the Atlantic facing Hutchinson Island in southeastern Florida. The second fan, deposited by hurricane Ivan is located on the Gulf-facing Santa Rosa Island in northwestern Florida. Subsurface imaging using a 250 MHz Ground penetrating radar profiling …

In Situ Screening To Optimize Variables In Organic Reactions, David Berkowitz, Mohua Bose, Sungjo Choi

Department of Chemistry: Faculty Publications

A biphasic process for rapid screening of organic reactions comprising monitoring relative rates of parallel organic reactions. The screening process is suitable to determine the efficacy of different reactants, process conditions, and process enhancers such as catalysts or promoters. The biphasic process also allows multiple samples to be analyzed/monitored simultaneously. In addition because enzymes are used to monitor the reaction product in this invention, when that product is chiral and an enantio-discriminating enzyme is used to monitor the product, in addition to the relative rates, enantioselectivities of a set of parallel organic reactions can also be determined. The monitoring is …

Women In Science: Biological Factors Should Not Be Ignored, Kingsley R. Browne

Cardozo Journal of Equal Rights & Social Justice

The article argues that biological and psychological differences between sexes contribute to the underrepresentation of women in certain fields, challenging the assumption that equal representation is always the appropriate goal. It critiques the notion that disparities necessarily indicate systemic flaws, emphasizing that freedom of choice should allow for different occupational outcomes without implying discrimination.
