Measurements and Simulations of Surface Dielectric Barrier Discharges Used as Plasma Actuators (2012)

This report is a Ph.D. dissertation performed under NRA cooperative agreement and submitted as part of the final report. Asymmetric surface dielectric barrier discharges (DBDs) have shown promise for use as aerodynamic actuators for active flow control. In this project we studied DBD actuators experimentally and numerically. Our DBDs used a symmetric triangular high voltage waveform to generate plasma in atmospheric pressure air. Time-averaged measurements indicated that the induced force of a single barrier actuator design (one electrode insulated from the plasma) can be increased exponentially above the results of previous studies by decreasing both the length and thickness of the electrode exposed to the plasma. This increased force may allow these devices to control flow separation in a wider range of flow environments. Experiments using an intensified digital camera to examine the plasma on time scales of a few nanoseconds showed that, in addition to the previously-observed filamentary and jet-like plasma structures, discharges with very thin exposed electrodes exhibited a weak but constant plasma immediately adjacent to those electrodes. In double-barrier actuators (both electrodes insulated), decreasing the diameter of the narrower electrode lead to increasing forces, and recorded images showed the simultaneous existence of both filamentary and jet-like plasma structures. The development and application of a time-dependent, two-dimensional computational fluid plasma model has aided in understanding the detailed physics of surface DBDs at all-time scales. For simulated single-barrier discharges, the model qualitatively reproduced the filamentary and jet-like micro-discharge structures. The model was somewhat successful in reproducing the observed characteristics of double-barrier actuators. For both actuator geometries, the model indicated that the majority of the forces induced on the neutral gas occur in between micro-discharges as the plasmas decay.
Sensitization to mite allergens and acute asthma in a tropical environment. (1999)

The objective of this study was to determine whether sensitization to certain aeroallergens is associated with acute asthma in Cartagena, Colombia. Ninety-nine subjects with acute asthma and 100 controls evaluated for other reasons were studied at a local emergency room. Sensitization was established by specific IgE determinations. Statistically significant differences between asthmatic subjects and controls were found in the prevalence of specific IgE to Dermatophagoides pteronyssinus, 64.6% vs. 28% (p = 0.0001); to Dermatophagoides farinae, 74.7% vs. 40% (p = 0.0001); to Euroglyphus maynei, 68.7% vs. 22% (p = 0.0001); and to Blomia tropicalis, 54.5% vs. 17% (p = 0.0001). The odds ratios were 4.9; 4.4; 7.7 and 5.8, respectively. In contrast, there was no significant difference between subjects with asthma and controls in the prevalence of specific IgE to Alternaria tenuis: 4% vs. 1% (p = 0.35); to Paspalum notatum (Bahia grass): 28% vs. 19% (p = 0.16); to Periplaneta americana (American cockroach): 21% vs. 19% (p = 0.83); to Ambrosia artemisifolia (short ragweed): 12% vs. 23% (p = 0.11); and to cat epithelium: 5% vs. 1% (p = 0.17). The results suggest that sensitization to domestic mites in subjects who reside in this tropical city is associated with acute asthma that requires emergency room treatment.
Flow of adsorbable gases and vapours in a microporous medium, I. Single sorbates (1963)

Abstract Adsorption and flow measurements have been made in a microporous membrane of a consolidated, high specific area, gas-sorbing carbon. The gases and vapours studied were SO2, CO2, N2, A, and He, over a range of temperatures and pressures. Steady-state permeation rates have shown that in the membrane used, for the vapours SO2 and CO2, and for N2 and A at liquid oxygen and nitrogen temperatures, flow is dominated by the flux of the adsorbed film. Even for nitrogen at 190 °K adsorbed flow is considerably larger than gas-phase flow. From the results surface diffusion coefficients have been evaluated which are characteristic functions of the amount adsorbed. The properties of these diffusion coefficients have been considered in relation to the pore structure and the coverage of the surface by adsorbate. Attention has been given to the transient state time-lags. Using the method of Frisch (1957), it has not proved possible to represent these time lags in terms of the steady-state diffusion coefficients, thus emphasizing the distinction between transient and steady -state diffusion in heterogeneous media.

Synthesis and Characterization of Nanoparticles, Nanotubes, Nanopans, and Graphene‐like Structures of Boron Nitride (2010)

Abstract By heating H 3 BO 3 with urea in 1 : 6 molar ratio, nanoparticles and nanotubes of BN are obtained. The urea–boric acid reaction can also be exploited to obtain graphene analogues of BN, with the number of layers depending on the relative proportions of the two reactants. Synthesis with a high proportion of urea yields a product containing graphene analogues of BN with an average of 2 layers. The surface area of BN increases with the decreasing number of layers, and the high‐surface‐area BN also exhibits high CO 2 adsorption. Few‐layer BN can be solubilized by interaction with Lewis bases. Nanopans and nanosheets formed by graphene‐like BN are generated by the vapor phase reaction of NH 3 and BBr 3 at 1223 K. Nanopans of BN, being reported for the first time, have a bottom comprising single‐layer BN and a wall of 0.7 nm height. The average inner volume of the nanopan is around 400 nm 3 .

Genomic approaches to elucidating the pathophysiology of renal diseases. (2001)

The physiological and pathological processes of the kidney as a whole can now be analyzed with a molecular precision at a genomic-scale. Using massively parallel cDNA microarray technology, the mRNA expression of thousands of genes can be quantified simultaneously. The advantages of microarray analyses include the ability to examine the interaction of several genes or the entire genome in a single experiment. Bioinformatics approaches such as data mining through mathematical condensation of the massive gene expression profiles are essential for elucidating molecular and biological logic underlying gene expression programs. Genes that encode similar protein components are often coordinately regulated. Recent application of gene expression profiling to the normal human renal cortical tissue, experimental in vitro and in vivo models has shown that cellular activation is accompanied by changes of hundreds of genes in parallel. The databases of gene expression emerging from these studies will be used to interpret the pathological changes in gene expression that accompany a variety of human renal diseases.
In-Plane and Out-of-Plane Load Testing and Evaluation of Sustainable Masonry Walls (2008)

This paper presents the results of a pilot study at Penn State University to compare the structural behavior of three types of masonry that have some sustainable attributes. The three masonry types chosen consisted of concrete masonry unit (CMU), autoclaved aerated concrete (AAC), and adobe. Design professionals are interested in the relative performance of sustainable wall systems and this pilot study was motivated because of the lack of such a comparative study. In the study reported in this paper, 4 ft x 4 ft wall specimens were tested in shear and flexure under dry and wet conditions. A specially made spray rack was used to simulate rain condition on wall specimens before structural tests for wet condition. Comparison of the test results and observations made during the tests are discussed.
1027 EFFECT OF NPK FERTILIZATION ON PRODUCTIVITY AND QUALITY OF CITRUS (1994)

Drip fertigation enables control of the root environment in regard to the volume of irrigated soil, the soil matric potential in the immediate vicinity of the roots and the concentration and composition of the minerals. Application of daily NPK fertilization to citrus was found to promote root production with a large surface area and maintenance of controlled NPK concentrations at various stages of growth and development resulted in high productivity due mainly to increased number of fruits produced. Continuous maintenance of appropriate NPK concentrations at the immediate vicinity of the roots during three successive years improved fruit size without apparent reduction in quality. This was attributed mainly to a well balanced crop load and mineral status as expressed in leaf mineral analyses.

Myosin-IIA and ICAM-1 Regulate the Interchange between Two Distinct Modes of T Cell Migration (2009)

How T cells achieve rapid chemotactic motility under certain circumstances and efficient cell surface surveillance in others is not fully understood. We show that T lymphocytes are motile in two distinct modes: a fast "amoeboid-like" mode, which uses sequential discontinuous contacts to the substrate; and a slower mode using a single continuously translating adhesion, similar to mesenchymal motility. Myosin-IIA is necessary for fast amoeboid motility, and our data suggests that this occurs via cyclical rear-mediated compressions that eliminate existing adhesions while licensing subsequent ones at the front of the cell. Regulation of Myosin-IIA function in T cells is thus a key mechanism to regulate surface contact area and crawling velocity within different environments. This can provide T lymphocytes with motile and adhesive properties that are uniquely suited toward alternative requirements for immune surveillance and response.

Electroless Addition of Platinum to SnO2 Nanopowders (2002)

A procedure based on electroless metal deposition using Sn(II) as the reductor, previously used for the efficient addition of controlled amounts of Pd to nanoscaled SnO2 powders, is now applied to add Pt, which is also an important sensitizer of semiconductor gas sensors. This study was performed with the aim of studying the possible application of this method for the addition of other metals, regardless of the appearance of new chemical features. The characterization of these powders using XRD, Raman spectroscopy, XPS, ICP, and HRTEM is presented and discussed, showing the feasibility of the proposed catalyst addition mechanism as a useful tool for improving of existing catalytic materials for gas sensors, even using different chemical reagents because of chemical restrictions, as happens in the case of platinum. A set of platinum salt concentrations and reducing agent ratios, as well as different annealing temperatures, was used to analyze the influence of these parameters on the morphology and composition of the samples. The results indicated the presence of homogeneously distributed metallic Pt nanoclusters of only a few nanometers in size on the SnO2 nanopowder surface.
High-resolution and high-speed CT in industry and research (2012)

The application of industrial CT covers many orders of magnitude of object sizes, ranging from freight containers (few meters) down to liquid foams (i.e. for food industry) or even parts of insects which are only several hundreds of micrometers in size. Similarly, the specifications for acquisition speed extend over some orders of magnitude, from hours to sub-second CT. We present the current technology in terms of X-ray sources and detectors, along with numerous applications from industry and materials research: e.g. industrial high-speed CT of car pistons, in situ micro-CT of milk foam decay at micrometer spatial resolution and 8 s scan time, as well as ex situ scans of tensile tested Nickel-alloys. The Fraunhofer Development Center X-ray Technology (Fürth, Germany) and the Chair of X-ray Microscopy (University Würzburg, Germany) are currently working on extending the technological limits, demonstrated, e,g. by the development of advanced X-ray detectors or a new inhouse CT system which comprises a high-brilliance liquid metal jet anode.
Non-Binary LDPC Code Design for the Poisson PPM Channel (2017)

This paper investigates the design of non-binary protograph low-density parity-check codes for the Poisson channel with m-ary pulse position modulation. The field order over which the code is constructed is matched to the pulse position modulation order yielding a coded modulation scheme. The optimization of the low-density parity-check code structure is performed via protograph density evolution on a surrogate m-ary erasure channel. The surrogate design is illustrated to be not only accurate, but also robust for a range of practical values of channel background noise and various modulation orders. As a result the proposed codes show excellent performance over the Poisson channel with pulse position modulation outperforming competing schemes. As a side-product of this paper, finite-length benchmarks on the block error probability are provided, together with a union bound to characterize the code performance in the error floor region.
Abstract 2077: Snail modulates stemness properties in hypoxic Glioblastoma (2014)

Abstract Introduction: Glioblastoma (GBM) is the most aggressive form of glioma characterized by hypoxic regions with surrounding areas of necrosis. Hypoxia is responsible for inducing cancer invasiveness via epithelial-mesenchymal transition (EMT), thereby promoting tumor aggressiveness and therapeutic resistance. HIF-1α is known to upregulate Snail in various cancers. Snail over expression correlates with cancer stem cell-like properties in cancers. The association of EMT and stemness properties plays a vital role in tumors progression and might helps in therapeutic targeting. We have, therefore, investigated the correlation of EMT and Stem cell markers in hypoxic GBM. Method: mRNA expression of 5 EMT, 3 stemness and 5 hypoxia markers were analyzed in the 31 GBM samples and U373MG glioma cell line maintained under normoxia (20% O2) and severe hypoxia (0.2% O2) conditions for 24, 48 and 72 hrs. Correlation and cluster analysis were applied using SPSS 11.5, Cluster 3.0 software etc and R-software. Result: In tumors, spearman correlation was found to be significant (p≤0.05) between EMT markers and Hypoxia markers. Of all EMT markers, Snail correlated significantly with the maximum hypoxia markers, including HIF-1α. In addition, Snail was significantly correlated with Stem cell markers SOX2 (p&amp;lt;0.01) and Nestin (p&amp;lt;0.05). Gene Cluster analysis in 31 GBM arranged in decreasing order of Snail expression showed significant upregulation of SOX2 and Nestin in the high Snail expressing tertile. This correlation of gene expression in tumors was validated by in-vitro expression analysis of the molecules in U373MG cells, where we assessed significant increase in the expression of hypoxia markers (HIF-1α, VEGF and CA9), EMT (Snail and LOX) and SC markers (SOX2 and OCT4) were significantly increased under severe hypoxic conditions. Interpretation &amp; conclusions: Our finding for the first time suggests the role of Snail in provoking stemness of cancer cells in hypoxic GBM, thereby promoting aggressiveness of GBM.

The possibilities of standard bipolar, CMOS, and BiCMOS processes with respect to their use for the manufacturing of optoelectronic integrated circuits (OEICs) as optical receivers will be compared. The improvement of the OEIC properties due to process modifications and application examples of silicon receiver OEICs will be further, major points of consideration.
Hyperactivity of Human DNase I Variants (1998)

Human DNase I, an enzyme used to treat cystic fibrosis patients, has been engineered to more effectively degrade double-stranded DNA to lower molecular weight forms by introducing positively charged amino acids at positions that can interact favorably with the proximal negatively charged phosphate groups of the DNA. A series of combination mutants having from one to six additional basic residues compared with the wild type has been constructed, expressed in human 293 cells, and characterized. The degree of hyperactivity for the mutants was highly dependent upon the conditions in various assays, including the concentration and length of the DNA substrate and the salt and divalent metal ion concentrations. The level of hyperactivity was inversely proportional to both DNA concentration and DNA length, consistent with the processive nicking mechanism for the hyperactive variants. Salt was inhibitory for wild type DNase I but actually enhanced the activity of the hyperactive variants. Under optimal conditions for wild type, variants with one additional positive charge possessed the highest activity, which was only severalfold greater than that for wild type. However, in the presence of low DNA concentrations and molecular weights, no Ca2+, and 150 mM NaCl, the variant with six engineered basic residues was most active, having >10,000-fold higher activity than the wild type enzyme. Therefore, any potential increase in potency for the hyperactive variants in vivo will be determined by the concentration, length, and environment of the DNA.
