Abstract International students, intercultural learning, and international exchange are becoming vital to higher education and dealing with them is becoming one of the essential roles of student affairs.
Integrating Rigorous Completions Optimization into Full Field Geocellular and Simulation Modeling (2005)

Summary In this paper, we will present workflows that incorporate two traditionally distinct disciplines within the petroleum engineering and geological domains: rigorous single-well completion optimization and field geocellular and simulation modeling. W e explore the details of this workflow and discuss the benefits of tightly linking the two disciplines. This paper describes an example of the workflow application to a commingled stacked tight gas play in the Rocky M ountains of the United States. In commingled stacked tight gas pay, gross intervals of thousands of feet are completed to enable maximum productivity. Typically seen are interbedded sequences of fluvial sandstones intermixed with shales, coals, and silty-sand deposits. Because of the heterogeneity seen on various scales, field modeling provides value in deciding optimum well drilling density, determining well location geometry based on hydraulic fracture azimuth and drainage pattern, and modeling various economic scenarios of development. M odels were built by integrating the seismic, petrophysical, geological, and hydraulic fracture data generated by different disciplines. The vertical and areal resolutions of the model were dictated by sand body sizes, reservoir gross thickness and heterogeneity, and fracture stages. The size of the hydraulic fracture jobs and well spacing were critical considerations in the selection of simulation cell sizes. M ajor challenges included upscaling both the geological features and the hydraulic fracture properties to simulation model scale in a reasonably accurate manner. A streamline-based flow model was utilized to upscale geological features. The model that best captured both the volumetric and the flow characteristics was chosen for further simulation modeling. Single-well and sector models were used to approximate the fracture properties that would be used in the final simulation model. The models were calibrated to the behavior of the wells and then used for forecasting performance after stimulation. A software program that took into account production and economic information was used for well and field development planning.
Association of Asymmetrical Facial Photodamage With Automobile Driving (1994)

Long-term sun exposure (UV-A and -B light) results in characteristic clinical changes of the skin (eg, wrinkles, lentigines, elastosis, roughness, and sallowness) collectively known as<i>photodamage</i>.<sup>1</sup>We observed that a number of our patients have asymmetrical facial photodamage, with the left side of the face appearing more severely photodamaged than the right side. We postulated that this perceived left-sided predominance of severe photodamage may have arisen from exposure to UV light while driving a left-hand-drive automobile. We performed a study designed to test this hypothesis. <h3>Methods.</h3> A total of 120 patients (age range, 43 to 81 years; mean, 62 years; 105 female and 15 male subjects) were recruited through the mail using a questionnaire that obtained the following information: age, sex, occupation, percentage of time spent as an automobile driver, number of years as a driver, number of hours driven per week, and the percentage of time driving with

Evaluation of Winter Wheats For Resistance to Hessian Fly, 1995 And 1996 (1997)

Abstract Commercial varieties and advanced breeding lines were evaluated for Hessian fly resistance in a field at the Southwest Branch Experiment Station near Plains, GA. In each year, lines were planted in single 3-ft rows in a RCB design with 3 replications. One row ft of plants was examined. In 1995, lines were evaluated on 5 May during dough stage and percentage of infested stems and immatures per stem counted. In 1996, evaluations were at full tillering on 14 Feb, when the percentage of infested plants and immatures per plant was recorded. Data were analyzed with ANOVA, and means were compared with protected LSD test.
The Differential Role of Protein Kinase C Isozyme in the Rapid Induction of Neurofilament Phosphorylation by Nerve Growth Factor and Phorbol Esters in PC12 Cells (1991)

We examined the short-term regulation of the phosphorylation of the mid-sized neurofilament subunit (NF-M) by kinases which were activated in rat pheochromocytoma (PC12) cells by nerve growth factor (NGF) and/or 12-O-tetradecanoylphorbol 13-acetate (TPA). We found that NGF and TPA, alone or in combination, increased (a) the incorporation of [32P]Pi into NF-M and (b) the rate of conversion of NF-M from a poorly phosphorylated to a more highly phosphorylated form. This was not due to increased synthesis of NF-M, because NGF alone did not increase NF-M synthesis and TPA alone or TPA and NGF together inhibited the synthesis of NF-M. Further, an increase in calcium/phospholipid-dependent kinase (PKC) activity resulting from the treatment of PC12 cells with NGF and TPA was observed concomitant with the increased phosphorylation of NF-M. This PKC activity was determined to be derived from the PKC alpha and PKC beta isozymes. Finally, when PC12 cells were rendered PKC-deficient by treatment with 1 muM TPA for 24 h, NGF maintained the ability to induce an increase in NF-M phosphorylation, though not to the level attained in cells which were not PKC-deficient. These data suggest that NGF with or without TPA stimulates NF-M phosphorylation as a result of a complex series of events which include PKC-independent and PKC-dependent pathways.
Low voltage tunable capacitors for RF MEM filters and antenna applications (2002)

The design and experimental evaluation of a very low voltage tunable capacitor is presented in this paper. Interdigital capacitors are designed and fabricated on high resistance silicon substrate. Tunable ferroelectric thin film is deposited on to the device and its tunability is measured using an RF network analyzer. It is observed that the capacitor has 80% tunability at 6 volts. In conventional micro fabrication techniques, metal is deposited on the top of a ferroelectric thin film and then develops the device layout by photolithographic and etching technique. However, in this paper, the thin film is deposited on the top of IDT. This helps to reduce the bias voltage and to eliminate the device micro fabrication problems on ferroelectric films. High dielectric constant films can dramatically reduce the device size and it could be possible to achieve desired size of microsensors using these devices. These low voltage tunable ferroelectric films are also useful for the design of phase shifters for phased array antennas and tunable RF MEM filters.
A Genetic Approach to Study Mechanisms of Cocaine Action<sup>a</sup> (1996)

The brain dopamine system is thought to be the major target for the neuropharmacological actions of psychomotor stimulants such as cocaine. To investigate the mechanisms of cocaine action, we used a genetic approach, the gene-targeting technique, and generated D1 dopamine receptor mutant mice. Locomotor activity analysis in response to cocaine indicates that, in contrast to control mice which showed a dose-dependent increase in locomotion, D1 receptor mutant mice exhibited a dose-dependent decrease, suggesting that D1 receptors play an essential role in mediating such effects. Extracellular single unit recording of dopamine sensitive nucleus accumbens neurons in the D1 receptor mutant mice and control mice revealed a marked reduction in the inhibitory effects of cocaine and dopamine on the generation of action potentials, suggesting that D1 receptors play a fundamental role in cocaine- and dopamine-mediated neurophysiological effects within the nucleus accumbens. From these analyses, we conclude that the D1 dopamine receptor plays essential roles in mediating these effects of cocaine. In the future, the use of this powerful genetic approach will be essential for elucidating the molecular components of the signal transduction pathway leading to anatomical, cellular and behavioral changes upon cocaine administration and dopamine neurotransmission.
Polarization-dependent photoionization cross sections and radiative lifetimes of atomic states in<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:mi>Ba</mml:mi><mml:mspace width="0.2em"/><mml:mn mathsize="8pt">I</mml:mn></mml:mrow></mml:math> (2006)

The photoionization cross sections of two even-parity excited states $5d6d\phantom{\rule{0.3em}{0ex}}^{3}D_{1}$ and $6s7d\phantom{\rule{0.3em}{0ex}}^{3}D_{2}$ of atomic Ba at the ionization-laser wavelength of $556.6\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ were measured. We found that the total cross section depends on the relative polarization of the atoms and the ionization-laser light. With density-matrix algebra, we show that, in general, there are at most three parameters in the photoionization cross section. Some of these parameters are determined in this work. We also present the measurement of the radiative lifetime of five even-parity excited states of barium.
PROTRACTED PARENTERAL DRUG INFUSION IN AMBULATORY SUBJECTS USING AN IMPLANTABLE INFUSION PUMP (1977)

Cell-aware test (CAT) explicitly targets defects inside library cells and therefore significantly reduces the amount of test escapes compared to conventional automatic test pattern generation (ATPG). Our CAT flow consists of three steps: (1) defect-location identification (DLI), (2) defect characterization based on<br/>detailed analog simulation of the cells, and (3) cell-aware automatic test pattern generation (ATPG). This paper focuses on Step 1, as quality and cost are determined by the set of cell-internal defect locations considered in the remainder of the flow. Based on technology inputs from the user and a parasitic extraction (PEX) run that analyzes the cell layouts, we derive a set of open defects on and short defects between both transistor terminals and intra-cell interconnects. The full set of defect locations is stored for later use during failure analysis. Through dedicated DLI algorithms, we identify a compact subset of defect locations for defect characterization and ATPG, in which we include only<br/>one representative defect location for each set of equivalent defects locations. For Cadence’s GPDK045 library, the compact subset contains only 2.8% of the full set of defect locations and reduces the time required for defect characterization with the same ratio.
EVALUATION OF DANGEROUS GOODS PRESSURE RELIEF VALVE PERFORMANCE PHASE 2 - STEAM-BASED TESTS: PRELIMINARY RESULTS (1997)

Transport Canada's Evaluation of Dangerous Goods Pressure Relief Valve Performance project is an effort to quantify the dynamic behaviour of commercially available transportation industry pressure relief valves (PRVs). To this end, a steam-based pressure relief valve test facility (PRVTF or VTF) uniquely capable of measuring dynamic pressures and flows during blowdown was set up and commissioned. Sixty valves representing equivalent designs from three manufacturers (1 NPT, semi-internal, 312 psi set pressure, brass construction, ~1160 scfm flow capacity at 20% overpressure) were obtained to serve as the initial test group. The valves used for testing were unidentified. After being statically tested on air the valves were dynamically tested on the new VTF. The objectives of this initial dynamic test sequence were: to determine PRV behaviour in a variety of simulated single-phase venting scenarios; to prove the ability of the VTF to measure the operating characteristics of PRVs; to gain experience with dynamic PRV testing methodologies and analysis techniques to facilitate more complex studies in the future; and to identify the effect of pressurization rate on the cycling frequency of the specimen relief valves.
Meatal facial nerve decompression in acoustic neuroma resection. (1995)

Delayed facial palsy occurs after approximately 15% of acoustic neuroma resections. Whereas in most cases facial nerve function recovers satisfactorily, in about 12% of cases delayed facial palsy may have a poor functional recovery. The fate of facial nerve function was studied in 55 consecutive translabyrinthine acoustic neuroma resections, 23 of whom underwent meatal facial nerve decompression (MFND) at the time of tumor resection. The facial nerve results also were reviewed in 19 middle cranial fossa resections, of whom 14 underwent MFND. There was a bimodal distribution of the delayed palsies, with one group having the onset of palsy within hours to 2 days after surgery and the second group having onset of palsy up to 17 days after surgery. The poorest recoveries were seen in the first group. Although the effect was not statistically significant due to the small sample size, the chance of facial weakness in patients who underwent MFND after translabyrinthine surgery was about 40% less than in those who did not undergo decompression. The apparent protective effect of MFND was increased when the confounding factors of tumor size and degree of resection were taken into account, although the effect was not statistically significant. The duration of palsy was shorter and ultimate recovery better among the patients who underwent facial nerve decompression than in those who did not. Of the translabyrinthine patients who underwent MFND, 100% had House-Brackmann grade I-II function at 2 years, whereas 87% of patients who did not have MFND had grade I-II function and 13% had grade III-IV function. Without MFND, 57% of translabyrinthine patients whose onset of facial palsy was within 2 days of surgery had grade III-IV facial nerve function.
Characterization of α-NPD Thermally Deposited on Hydrogen-Terminated Single-Crystal Chemical-Vapor-Deposited Diamond Films (2003)

We have investigated the interface formation between hydrogen-terminated homoepitaxial (100) chemical-vapor-deposited (CVD) diamond films and thermally deposited N,N'-diphenyl-N,N'-bis(1-naphthyl)-1,1'biphenyl-4,4''diamine (α-NPD). The deposited α-NPD was found to form islands at the earliest initial stage, and to subsequently become a continuous film. It turned out that both X-ray photoemission peak positions of C1s and N1s electrons shifted to lower binding energies after the interface formation between sufficiently thin α-NPD films (<10 nm) and the H-terminated p-type diamond, indicating that a substantial interaction between the H-terminated CVD diamond and the deposited α-NPD occurred. The possible origin of the interaction is discussed in relation to charge transfer and a relative change in the energy levels between α-NPD and the H-terminated diamond. Photoluminescence spectra taken from the deposited α-NPD films showed a broad emission peak at 435 nm with an excitation peak at 350 nm, differing from those taken from α-NPD in a chloroform solvent.
An ATM cross-connect system for broadband transport networks based on virtual path concept (1990)

A broadband transport network architecture based on the virtual path concepts for ISDN is outlined. It is demonstrated that ATM (asynchronous transfer mode) cross-connected systems for provisioning virtual paths play an essential role in the network, and have a great impact on network architecture. The design of large-capacity ATM cross-connect systems using an input queuing scheme and a self-routing switch is presented. Efficient contention control algorithms (scheduling algorithms) are proposed in order to improve the throughput, and a distributed design example is described. A planar homogeneous self-routing switch is also proposed for easy expansion of switch size. This architecture allows the development of large-capacity ATM cross-connect systems for future broadband transport networks.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

1. What Is Near-Surface Geophysics? (2005)

Near-surface geophysics uses the investigational methods of geophysics to study the nature of the very outermost part of the earth's crust. Man interacts with this part of the earth's crust: he walks on it; he drills and excavates into it; he constructs structures on and in it; he utilizes its water and mineral resources; and his wastes are stored on and in it and seep into it. The very outermost part of the Earth's crust is extremely dynamic—in both technical (physical properties) and nontechnical (political, social, legal) terms—which leads to both technical and nontechnical challenges that are much different than the challenges faced by “traditional” applications of geophysics for regional geologic mapping and for oil and gas exploration (see Chapter 2).
Aided target recognition from 3D laser radar data (2004)

This paper presents our ongoing research activities on target recognition from data generated by 3-D imaging laser radar. In particular, we focus on future full flash imaging 3-D sensors. Several techniques for laser range imaging are applied for modelling and simulation of data from this kind of 3-D sensor systems. Firstly, data from an experimental gated viewing system is used. Processed data from this system is useful in assisting an operator in the target recognition task. Our recent work on target identification at long ranges, using range data from the gated viewing system, provides techniques to handle turbulence, platform motion and illumination variances from scintillation and speckle noise. Moreover, the range data is expanded into 3-D by using a gating technique that provides reconstruction of the target surface structure. This is shown at distances out to 7 km. Secondly, 3-D target data is achieved at short ranges by using different scanning laser radar systems. This provides high-resolution 3-D data from scanning a target from one single view. However, several scans from multiple viewing angles can also quite easily be merged for more detailed target representations. This is, for example, very useful for recognizing targets in vegetation. Hereby, we achieve simulated 3-D sensor data from both short and long ranges (100 meters out to 7 km) at various spatial resolutions. Thirdly, real data from the 3-D flash imaging system by US Air Force Research Lab (AFRL/SNJM), Wright Patterson Air Force Base, has recently been made available to FOI and also used as input in the development of aided target recognition methods. High-resolution 3-D target models are used in the identification process and compared to the 3-D target data (point cloud) from the various laser radar systems. Finally, we give some examples from our work that clearly show that future 3-D laser radar systems in cooperation with signal- and image analysis techniques have a great potential in the non-cooperative target recognition task and will provide several new and interesting capabilities, for example, to reveal targets hidden in vegetation.
Hemostatic efficacy of chitosan-based bandage for closure of percutaneous arterial access sites: An experimental study in heparinized sheep model (2010)

The externally applied HCB in heparinized sheep was safe and effective. It significantly shortened time to hemostasis at the SFA access sites following 8F sheath removal. Proper application of the HCB was necessary to shorten hemostasis and prevent hematoma formation. The HCB should be tested in a clinically controlled study to evaluate its efficacy in humans.

<i>trans</i> -10, <i>cis</i> -12 Conjugated Linoleic Acid Induces Depolarization of Mitochondrial Membranes in HT-29 Human Colon Cancer Cells: A Possible Mechanism for Induction of Apoptosis (2009)

Conjugated linoleic acid (CLA), which is naturally present in a variety of foods such as milk fat and the meat of ruminant animals, has been demonstrated to exert chemoprotective effects in several tissues in experimental animals. CLA is a collective term, which denotes one or more positional and geometric isomers of octadecadienoic acid, with cis-9,trans-11 (c9t11) and trans-10,cis-12 CLA (t10c12) being the principal isomers in commercial preparations. We observed previously that physiological levels of CLA inhibited HT-29 cell growth, and the growth inhibitory effects of CLA were attributed to the effect of t10c12, but not c9t11. In the present study, we assessed the mechanisms by which physiological levels of CLA and t10c12 induce apoptosis in HT-29 cells. HT-29 cells were cultured for 3 days in serum-free medium in the presence of various concentrations of CLA (0-20 micromol/L) or t10c12 (0-4 micromol/L). Addition of CLA or t10c12 to culture medium resulted in a dose-dependent increase in the numbers of apoptotic cells. The results of western blot analysis of total cell lysates showed that CLA and t10c12 increased the levels of cleaved caspase-9, caspase-3, and poly(ADP-ribose) polymerase but did not alter the levels of Bcl-2 family member proteins. However, these fatty acids were shown to increase the translocation of Bad and Bax to the mitochondria, increase mitochondrial membrane permeability, and induce the release of cytochrome c and Smac/Diablo from the mitochondria. In addition, CLA and t10c12 diminished Akt content and Akt phosphorylation. These findings indicate that physiological levels of t10c12 induce apoptosis in HT-29 colon cancer cells, which is mediated via mitochondrion-mediated events associated with a decline in Akt activity, an increase in the translocation of the pro-apototic Bad and Bax to the mitochondria, and the subsequent disruption of normal mitochondrial membrane potential.
