Mathematics textbooks and state curriculum standards : an analysis of the alignment between the written and intended curricula
(University of Missouri--Columbia, 2007)
populous states that use a system of statewide textbook adoption and the five most populous states that are "open territory" comprised the state sample, while two popular elementary (K-6) textbook series and two popular middle grades (6-8) textbook series...
Synthesis and structure-activity relationship of a series of sigma receptor ligands
(University of Missouri--Columbia, 2007)
-activity relationships, a series of N-phenylpropyl- N'-benzylpiperazine and N-phenylpropyl-4-benzylpiperidine analogs systematically substituted on both phenyl rings was synthesized. These ligands were specifically designed to have certain substituents and substitution...
College students' information search behavior for spring break: an exploration in the concept of specialization
(University of Missouri--Columbia, 2007)
, than the other two groups. In regard to internal information source and word of mouth, the high specialization group also showed the highest value of the three groups. The medium specialization group, on the other hand, was more likely to place...
Uncertainty and tangible assets in firm investment : inter-industry evidence from APEC countries
(University of Missouri--Columbia, 2007)
This dissertation investigates how the role of cash flow changes with the uncertainty coming from oil price fluctuations, using the annual data obtained from COMPUSTAT global during the period of 1991 to 2004. I construct ...
Identification and characterization of glyphosate-resistant common ragweed
(University of Missouri--Columbia, 2007)
A revolution in production agriculture has occurred over the past decade; the development and use of herbicide-resistant crops. Glyphosate is an effective, broad spectrum and offers flexible application timing with minimal ...
Automating traffic studies at modern roundabouts: a feasibility study
(University of Missouri--Columbia, 2007)
The modern roundabout is growing in popularity as an alternative intersection design, however it presents engineers a new quandary. At a traditional intersection, traffic movements may more easily counted given vehicle ...
In vitro three dimensional biomechanical comparison of two internal fixation methods in equine adult radii
(University of Missouri--Columbia, 2007)
Radius fracture configurations conducive to internal fixation most often contain a spiral or oblique fracture of the distal diaphysis. The location and fracture configurations are biomechanically challenging because of the limited amount of bone...
Studies on radiometal chelator-bombesin peptide-based radiopharmaceuticals for tumor GRP-receptor subtype mediated radioimaging
(University of Missouri--Columbia, 2007)
displacement of [superscript 125]I-BBN from the human PC-3 prostate cancer cell line. Labeling with [superscript nat]In and [superscript 111]In were successfully performed. The degree of in vitro internalization and efflux of [superscript 111]In...
Characterization of disinfection by-product precursors from Missouri streams
(University of Missouri--Columbia, 2007)
The NOM contained in drinking water sources reacts with Cl2 to generate THMs and HAAs. THMs and HAAs are regulated by EPA because they pose a health hazard. The nature of the DBP precursors is complex and not well understood. ...
Firm access to capital markets in Europe
(University of Missouri--Columbia, 2007)
regime. This is a comparative empirical study of 14 European countries between 1992 and 2005. Using firm level data and a series of large panel of bank concentration and integration measures, this paper examines and analyzes financial constraints...
Heterochrony of floral and mating system characters between Nicotiana longiflora and N. plumbaginifolia
(University of Missouri--Columbia, 2007)
The evolution of selfing is one the most fascinating and common trends observed in flowering plants. Selfing flowers are often smaller than their outcrossing relatives, with reduced reproductive effort. The selfing species ...
The undoing of the self: an artistic exploration
(University of Missouri--Columbia, 2007)
This creative research investigated the nature of interpersonal relationships through the lens of Theravada Buddhism and took the form of interactive video, performance and installation. Tangible materials, video projections ...
Materials study supporting thermochemical hydrogen cycle sulfuric acid decomposer design
(University of Missouri--Columbia, 2007)
A laboratory scale sulfuric acid decomposer simulator was constructed at the Nuclear Science and Engineering Institute at the University of Missouri- Columbia. The simulator was capable of producing the temperatures and corrosive environments...
The validity of morphological features and osteological markers in reconstructing habitual activities
(University of Missouri--Columbia, 2007)
Bony morphological features have been used to reflect biomechanical behavioral patterns among archaeological populations. Of most recent ones is the anterior femoral curvature (AFC). It has been proposed as a valid indicator ...
Energy transfer at gas-liquid interface : towards energetic materials
(University of Missouri--Columbia, 2007)
system, representing nitramine-type energetic materials. Having had a good potential description for the nitromethane molecule including all internal degrees of freedom, we generated simplified molecular systems based on the original nitromethane model...
Rational design of split gene vectors to expand the packaging capacity of adeno-associated viral vectors
(University of Missouri--Columbia, 2007)
Adeno associated viruses (AAV) have recently been demonstrated as a very promising gene delivery vehicle. But the limited packaging capacity of AAV vectors (4̃.7kb) hinders their application for diseases involving large ...
Development of a fluorescence resonance energy transfer optical nanoscale biosensor based on a liquid-core waveguide platform
(University of Missouri--Columbia, 2007)
In order to produce a more versatile, adaptable, and effective method for detection of biological analytes, a self-contained and robust fluorescent optical biosensor architecture utilizing fluorescence resonance energy ...
Comparison of rainfall energy and soil erosion parameters from a rainfall simulator and natural rain
(University of Missouri--Columbia, 2007)
Numerous studies have used artificial rainfall to quantify relationships for runoff and soil detachment. Application of these results to natural rainfall conditions is dependent in part on how well artificial rainfall ...
The effect of modafinil on psychostimulant-evoked [³H]dopamine release from rat striatal slices
(University of Missouri--Columbia, 2007)
by the nAChR antagonist mecamylamine and modafinil did not alter nicotine-evoked [³H]DA overflow, making it unlikely that nAChRs are important for modafinil's mechanism of action. The DAT inhibitor nomifensine (10 µM) attenuated (~50%) modafinil-evoked [³H...
