The Electrocatalystic Investigation Of 3,4-Dihydroxybenzoic Acid On The Modified Multiply Wall Carbon Nanotubes, Ming-Qi Li, Duo-Chang Cai, Xiao-Ying He
The Electrocatalystic Investigation Of 3,4-Dihydroxybenzoic Acid On The Modified Multiply Wall Carbon Nanotubes, Ming-Qi Li, Duo-Chang Cai, Xiao-Ying He
Journal of Electrochemistry
The electrochemical behavior of 3,4-Dihydroxybenzoic acid(DHBA) on modified multiply wall carbon nanotubes electrode was investigated by cyclic voltammetry(CV) and square wave voltammetry(SWV). Results show that in 0.1 mol/L HCl solutions the modified carbon nanotube electrode has an obvious electrocatalytic effect on the oxidation and deoxidization of DHBA. The oxidation current of DHBA is linear to it's concentration in the range of 4.0×10-6~1.0×10-4 mol/L and 2.0×10-4~8.0×10-4 1mol/L with correlation coefficient of 0.9995 and 0.9992. The detection limit is 1.0×10-6 mol/L.

Inclusive jet cross sections in photoproduction for events containing a D* meson have been measured with the ZEUS detector at HERA using an integrated luminosity of 78.6 pb-1. The events were required to have a virtuality of the incoming photon, Q2, of less than 1 GeV2, and a photon-proton centre-of-mass energy in the range 130 < Wγp < 280 GeV. The measurements are compared with next-to-leading-order (NLO) QCD calculations. Good agreement is found with the NLO calculations over most of the measured kinematic region. Requiring a second jet in the event allowed a more detailed comparison with QCD calculations. The measured dijet cross sections are also compared to Monte Carlo (MC) models which incorporate leading-order matrix elements followed by parton showers and hadronisation. The NLO QCD predictions are in general agreement with the data although differences have been isolated to regions where contributions from higher orders are expected to be significant. The MC models give a better description than the NLO predictions of the shape of the measured cross sections. © 2005 Elsevier B.V. All rights reserved.

As the Semantic Web gains importance for sharing knowledge on the Internet this has lead to the development and publishing of many ontologies in different domains. When trying to reuse existing ontologies into their applications, users are faced with the problem of determining if an ontology is suitable for their needs. In this paper, we introduce OntoQA, an approach that analyzes ontology schemas and their populations (i.e. knowledgebases) and describes them through a well defined set of metrics. These metrics can highlight key characteristics of an ontology schema as well as its population and enable users to make an informed …

The neuronal nitric-oxide synthase (nNOS) flavoprotein domain (nNOSr) contains regulatory elements that repress its electron flux in the absence of bound calmodulin (CaM). The repression also requires bound NADP(H), but the mechanism is unclear. The crystal structure of a CaM-free nNOSr revealed an ionic interaction between Arg1400 in the C-terminal tail regulatory element and the 2′-phosphate group of bound NADP(H). We tested the role of this interaction by substituting Ser and Glu for Arg1400 in nNOSr and in the full-length nNOS enzyme. The CaM-free nNOSr mutants had cytochrome c reductase activities that were less repressed than in wild-type, and this …

We report on a search for Bs0→µ+µ- and Bd0→µ+µ- decays in pρ̅ collisions at √8=1.96 TeV using 364 pb-1 of data collected by the CDF II detector at the Fermilab Tevatron Collider. After applying all selection requirements, we observe no candidates inside the Bs0 or Bd0 mass windows. The resulting upper limits on the branching fractions are Ɓ (Bs0→µ+µ-)<1.5×10-7 and Ɓ (Bd0→µ+µ-)<3.9×10-8 at 90% confidence level.

Autonomous mobile entity navigation through dynamic and unknown environments is an essential part of many mission critical applications like search and rescue and fire fighting. The dynamism of the environment necessitates the mobile entity to constantly maintain a high degree of awareness of the changing environment. This criteria makes it difficult to achieve good navigation performance by using just on-board sensors and existing navigation methods and motivates the use of wireless sensor networks (WSNs) to aid navigation. In this paper, we present a novel approach that integrates a roadmap based navigation algorithm with a novel network query protocol called Roadmap …

Theses and Dissertations
Through the use of generalized spherical harmonic basis functions a spectral representation is used to model the microstructure of cubic materials. This model is then used to predict the macroscopic elastic and plastic properties of materials with cubic crystal symmetry and various sample symmetry including triclinic and axial—symmetric. Building on the work of citeN{Barnett-FractureMechanics} the influence that anisotropy has on the fatigue response of the material is also modeled. This is accomplished through using the effective elastic stiffness tensor in the computation of crack extension force G. The resulting material model and macroscopic property calculations are the foundation for …

The purpose of this study was to examine the attitudes of head coaches in the New Jersey Athletic Conference (NJAC) regarding the academic support services provided to student athletes. Of related interest was whether the coaches found a need for these services to be provided by the athletic department. Seventy-five head coaches in the NJAC completed the survey to evaluate the attitudes and academic support services. Results showed a statistically significant relationship between years in coaching and attitudes of academic support services. The findings suggested that the head coaches in the NJAC believe that there is a need for academic …
Generating Data-Extraction Ontologies By Example, Yuanqiu Zhou
Generating Data-Extraction Ontologies By Example, Yuanqiu Zhou
Theses and Dissertations
Ontology-based data-extraction is a resilient web data-extraction approach. A major limitation of this approach is that ontology experts must manually develop and maintain data-extraction ontologies. The limitation prevents ordinary users who have little knowledge of conceptual models from making use of this resilient approach. In this thesis we have designed and implemented a general framework, OntoByE, to generate data-extraction ontologies semi-automatically through a small set of examples collected by users. With the assistance of a limited amount of prior knowledge, experimental evidence shows that OntoByE is capable of interacting with users to generate data-extraction ontologies for domains of interest to …

The second OH overtone transition of the trans-perp conformer of peroxynitrous acid (tp-HOONO) is identified using infrared action spectroscopy. HOONO is produced by the recombination of photolytically generated OH and NO(2) radicals, and then cooled in a pulsed supersonic expansion. The second overtone transition is assigned to tp-HOONO based on its vibrational frequency (10 195.3 cm(-1)) and rotational band contour, which are in accord with theoretical predictions and previous observations of the first overtone transition. The transition dipole moment associated with the overtone transition is rotated considerably from the OH bond axis, as evident from its hybrid band composition, indicating …

All Computer Science and Engineering Research
Popular security techniques such as public-private key encryption, firewalls, and role-based access control offer significant protec-tion of system data, but offer only limited protection of the computations using that data from significant interference due to accident or adversarial attack. However, in an increasing number of modern systems, ensuring the reliable execution of system activities is every bit as important as ensuring data security. This paper makes three contributions to the state of the art in protection of the execution of system activities from accidental or adversarial interference. First, we consider the motivating problem of CPU-focused denial of service attacks, and …

Marketing Military Service Benefits Segmentation Based On Generalized And Restricted Exchange, Caroline Fisher, Kimball P. Marshall
Marketing Military Service Benefits Segmentation Based On Generalized And Restricted Exchange, Caroline Fisher, Kimball P. Marshall
Business and Information Technology Faculty Research & Creative Works
Willingness to engage in exchange is based on desired benefits. In typical commercial transactions, restricted exchange benefits dominate. However, public policy, social marketing situations might require consideration of both restricted and generalized exchange benefits. Applying factor analysis, cluster analysis and cross-tabulation, this paper reports research that has successfully segmented a young adult target market regarding interest in military service based on considerations of generalized and restricted exchange motivations. This research contributes to a growing body of literature on generalized exchange as a key conceptual element for social marketing. Results demonstrate the utility of the generalized exchange concept in identifying amarket …

Freshwater Mussel Survey Of The 39-Mile District - Missouri National Recreational River, South Dakota And Nebraska, Jeff Shearer, Doug Backlund, Stephen K. Wilson
School of Natural Resources: Faculty Publications
Freshwater mussel (Bivalvia: Unionida) surveys were conducted on the 39-Mile District of the Missouri National Recreational River (MNRR) between Ft. Randall Dam, South Dakota and Running Water, South Dakota from October 2004 to September 2005. Fortynine locations within the 39-Mile District were inspected for the presence of mussel populations. Mussels (live individuals or dead shells) were collected at only 37% (18 of 49) of the sites. Of the seven mussel species collected during this survey, the fragile papershell Leptodea fragilis and pink papershell otamilus ohiensis were the most common. The paper pondshell Utterbackia imbecillis and mapleleaf Quadrula quadrula were rare …
