Negative Dielectrophoretic Capture Of Bacterial Spores In Food Matrices, Mehti Koklu, Seungkyung Park, Suresh D. Pillai, Ali Beskok

Mechanical & Aerospace Engineering Faculty Publications

A microfluidic device with planar square electrodes is developed for capturing particles from high conductivity media using negative dielectrophoresis (n-DEP). Specifically, Bacillus subtilis and Clostridium sporogenes spores, and polystyrene particles are tested in NaCl solution (0.05 and 0.225 S/m), apple juice (0.225 S/m), and milk (0.525 S/m). Depending on the conductivity of the medium, the Joule heating produces electrothermal flow (ETF), which continuously circulates and transports the particles to the DEP capture sites. Combination of the ETF and n-DEP results in different particle capture efficiencies as a function of the conductivity. Utilizing 20 μm height DEP chambers, “almost complete” and …

Center For Academic Excellence: Annual Report 2009-2010, Patrice Hudson, Leslie G. Mcbride, Kevin Kecskes, Amy Spring, Janelle De Carrico Voegele, Michael Chamberlain, Vincent Schreck

Community Health Faculty Publications and Presentations

Admittedly, a certain amount of tedium is involved in assembling an annual report. Retrieving, verifying, and summarizing all the data generated from CAE’s programs and services during the year feels a lot like double-checking references in a manuscript before sending it off for review. It’s a necessary part of the larger project; sometimes we are surprised.

Somewhere in the midst of the process, we may suddenly see a project from an entirely diff erent perspective, identify a theme that ties together threads or themes we hadn’t realized previously were connected, or more clearly see why faculty members may (or may …

Spectroscopic And Computational Studies Of The Laser Photolysis Of Matrix Isolated 1,2-Dibromoethanes: Formation And Fate Of The Bromoethyl Radicals, A. Kalume, L. George, P. Z. El-Khoury, Alexander N. Tarnovsky, S. A. Reid

Chemistry Faculty Publications

We report experimental and computational studies of the photolysis of atmospherically important 1,2-dibromoethanes (1,2-C(2)X(4)Br(2); X = H, F) in Ar matrixes at 5 K. Using the pulsed deposition method, we find that significant conformational relaxation occurs for 1,2-C(2)H(4)Br(2) (EDB; observed anti/gauche ratio =30:1) but not for 1,2-C(2)F(4)Br(2) (TFEDB; anti/gauche = 3:1), which is traced to a larger barrier to rotation about the C-C bond in the latter. Laser photolysis of matrix-isolated EDB at 220 nm reveals the growth of infrared bands assigned to the gauche conformer and C(2)H(4)-Br(2) charge transfer complex (both as major products), and the C(2)H(4)Br radical and …

U–Pb Zircon Geochronology And Tectonostratigraphy Of Southern Liverpool Land, East Greenland: Implications For Deformation In The Overriding Plates Of Continental Collisions, Scott M. Johnston, Ebbe H. Hartz, Hannes K. Brueckner, George E. Gehrels

Physics

The East Greenland Caledonides formed in the overriding plate as Baltica was subducted westward beneath Laurentia from 460 to 360 Ma, and offer a unique opportunity to investigate lower crustal deformation in the overriding plates of continental collisions. Field work and new zircon geochronology from gneisses in southern Liverpool Land, exposed in the hinterland ~100 km east of the nearest Caledonian gneisses, define three tectonostratigraphic units that are, from the bottom up, the eclogite+peridotite-bearing Tværdal complex and the granulite-facies Jættedal complex in the footwall of the top-N Gubbedalen shear zone, and the Hurry Inlet granite and associated paragneiss screens in …

The Relationship Between The Percentage Of African-American Teachers On Public School Secondary Campuses And The Percentage Of African-American Students Passing The Texas Assessment Of Knowledge And Skills Test (Taks), Victor S. Nixon

Doctoral Dissertations and Projects

No Child Left Behind has caused educators to take a critical look at the achievement levels of all population groups on campus. African-American student achievement can no longer be masked by the achievement levels of other student populations. Educators must develop strategies to reduce the African-American achievement gap in order to meet Adequate Yearly Progress. This study examined the relationship between the percentage of African-American teachers on secondary Texas campuses and African-American student achievement. Academic achievement was measured by the use of the Texas Assessment of Knowledge and Skills Test (TAKS). The American College Test (ACT) and the Scholastic Aptitude …

Adaptive Quadrant Filter Based Phase Locked Loop System, L. Shi, Mariesa Crow

Electrical and Computer Engineering Faculty Research & Creative Works

Phase-Locked-Loop (PLL) is one of the key technologies extensively used in grid connected power electronics system. A good PLL system can detect the grid phase angle and frequency fast and accurately, and additionally it can extract the positive sequence (or fundamental component for single phase system) exactly. In real applications, source signal (voltage or current) sensed for PLL usually includes harmonic distortion, unbalanced components, noises and frequency variations. Conventional PLL strategy cannot solve all the problems, especially the unbalanced and harmonic distortion. There is a trade-off between the dynamic response and phase angle tracking accuracy. Different PLL solutions are proposed …

Uncertainty Quantification Integrated To Cfd Modeling Of Synthetic Jet Actuators, Srikanth Adya, Daoru Frank Han, Serhat Hosder

Mechanical and Aerospace Engineering Faculty Research & Creative Works

The Point-Collocation Non-intrusive Polynomial Chaos (NIPC) method has been applied to a stochastic synthetic jet actuator problem used as one of the test cases in the CFDVAL2004 workshop to demonstrate the integration of computationally efficient uncertainty quantification to the high-fidelity CFD modeling of synthetic jet actuators. The test case included the simulation of an actuator generating a synthetic jet issued into quiescent air. The Point-Collocation NIPC method is used to quantify the uncertainty in the long-time averaged u and v-velocities at several locations in the flow field due to the uniformly distributed uncertainty introduced in the amplitude and frequency of …

Integration Of Antennas And Solar Cells For Autonomous Communication Systems, Maria Jose Roo Ons

Doctoral

Solar energy is becoming an attractive alternative for powering autonomous communication systems. These devices often involve the use of separate photovoltaics and antennas, which demand a compromise in the utilization of the limited space available. This thesis deals with the design, analysis, fabrication and validation of different techniques for the integration of antennas and solar cells in a single multifunctional device. Four different photovoltaic technologies are considered within this work, namely, polycrystalline silicon (poly-Si), monocrystalline (mono-Si) emitter-wrap-through (EWT) rear contact solar cells, amorphous silicon (a-Si) thin film on glass substrate, and bifacial solar cells. The use of a poly-Si solar …

Enumeration Refactoring: A Tool For Automatically Converting Java Constants To Enumerated Types, Raffi Khatchadourian, Benjamin Muskalla

Publications and Research

Java 5 introduces several new features that significantly improve older Java technology. We consider the new enum construct, which provides language support for enumerated types. Before Java 5, programmers needed to employ various patterns to compensate for the absence of enumerated types in Java. Unfortunately, these compensation patterns lack several highly desirable properties of the enum construct, notably type-safety. We demonstrate an automated refactoring tool called Convert Constants to Enum for transforming legacy Java code to use the new enumeration construct. An interprocedural type inferencing algorithm that tracks the flow of enumerated values drives the approach, and the tool is …

Limitations On Simultaneity In Sign Language, Donna Jo Napoli, R. Sutton-Spence

Linguistics Faculty Works

When we converse, information is often conveyed in multiple ways. For those using spoken language, we have, besides the vocal tract, nonverbal articulators as well, including eye gaze (Hanna & Brennan 2007), gesture (Kendon 2004), facial expression (Busso & Narayanan 2007), lip pointing (Sherzer 1983), and puffed cheeks (Sherzer 1993). Likewise, for those using a sign language, we have, besides the hands, nonmanual articulators as well, including facial expressions, eye gaze, mouth, and body posture (Baker & Padden 1978). In this short report we investigate how much information can be simultaneously expressed in sign language (by counting ‘propositions’) and conclude …

Macroevolutionary Patterns In The Evolutionary Radiation Of Archosaurs (Tetrapoda: Diapsida), S. L. Brusatte, M. J. Benton, G. T. Lloyd, M. Ruta, Steve C. Wang

Mathematics & Statistics Faculty Works

The rise of archosaurs during the Triassic and Early Jurassic has been treated as a classic example of an evolutionary radiation in the fossil record. This paper reviews published studies and provides new data on archosaur lineage origination, diversity and lineage evolution, morphological disparity, rates of morphological character change, and faunal abundance during the Triassic–Early Jurassic. The fundamental archosaur lineages originated early in the Triassic, in concert with the highest rates of character change. Disparity and diversity peaked later, during the Norian, but the most significant increase in disparity occurred before maximum diversity. Archosaurs were rare components of Early–Middle Triassic …

Cloud Computing:Strategies For Cloud Computing Adoption, Faith Shimba

Dissertations

The advent of cloud computing in recent years has sparked an interest from different organisations, institutions and users to take advantage of web applications. This is a result of the new economic model for the Information Technology (IT) department that cloud computing promises. The model promises a shift from an organisation required to invest heavily for limited IT resources that are internally managed, to a model where the organisation can buy or rent resources that are managed by a cloud provider, and pay per use. Cloud computing also promises scalability of resources and on-demand availability of resources.

Although, the adoption …

Nano-Imprinted Thin Films Of Reactive, Azlactone-Containing Polymers: Combining Methods For The Topographic Patterning Of Cell Substrates With Opportunities For Facile Post-Fabrication Chemical Functionalization, Nathaniel J. Fredin, Ryan M. Flessner, Christopher M. Jewell, Shane L. Bechler, Maren E. Buck, David M. Lynn

Chemistry: Faculty Publications

Laser scanning confocal microscopy (LSCM) and atomic force microscopy (AFM) were used to characterize changes in nanoscale structure that occur when ultrathin polyelectrolyte multilayers (PEMs) are incubated in aqueous media. The PEMs investigated here were fabricated by the deposition of alternating layers of plasmid DNA and a hydrolytically degradable polyamine onto a precursor film composed of alternating layers of linear poly(ethylene imine) (LPEI) and sodium poly(styrene sulfonate) (SPS). Past studies of these materials in the context of gene delivery revealed transformations from a morphology that is smooth and uniform to one characterized by the formation of nanometer-scale particulate structures. We …

Can Propensity Score Analysis Relplicate Estimates Based On Random Evaluations Of School Choice? A Within-Study Comparison, Robert Bifulco

Center for Policy Research

The ability of propensity score analysis (PSA) to match impact estimates derived from random assignment (RA) is examined using data from the evaluation of two interdistrict magnet schools. As in previous within study comparisons, the estimates provided by PSA and RA differ substantially when PSA is implemented using comparison groups that are not similar to the treatment group and without pretreatment measures of academic performance. Adding pretreatment measures of the performance to the PSA, however, substantially improves the match between PSA and RA estimates. Although the results should not be generalized too readily, they suggest that nonexperimental estimators can, in …

Convergent Validity Of Self Reported Physical Activity With A Seven Day Recall, Benjamin J. Silber

Loma Linda University Electronic Theses, Dissertations & Projects

Accurate assessment of physical activity is important to studies interested in the relationship between physical activity and other variables. Questionnaires are the only feasible means for large-scale sampling but such self-report measures require validation due to their inherent subjectivity. The Adventist Health Study-2 (AHS-2) survey includes exercise items that were validated in the present investigation. A calibration study examined self-reports of exercise with two phone calls to 1,000 participants in which an interview-assisted 7-day physical activity recall was completed by a random sample of AHS-2 participants. Inter-index correlations both within the survey and between the survey and the 7-day physical …

While Our Results Are of Theoretical Interest, They Definitely Also Have Important Applications in Statistics and Physics. …

Comparison Of Non-Surgical And Surgical Endodontic Retreatment: A Systematic Review, Robert Corr

Loma Linda University Electronic Theses, Dissertations & Projects

Primary root canal therapy has been shown to be a predictable procedure with a high degree of success ^1-4, however failures can occur after treatment. Treatment options for the preservation of teeth that have had previous endodontic treatment but demonstrate persistent disease include non-surgical (orthograde) or surgical (retrograde) endodontic retreatment, assuming the tooth is restorable, periodontally sound, and the patient desires to retain the tooth. The purpose of this study was to conduct a systematic review of the current available evidence to compare the clinical and radiographic outcomes of nonsurgical with those of surgical endodontic retreatment. Methodology began with …
