Electron energy-loss spectroscopy study of the electronic structure of boron nitride nanotubes (1998)

Electron energy-loss spectra were obtained from single boron-nitride nanotubes (BNTs), which were synthesized by the arc-discharge method. The π and π + σ plasmon energies of the BNTs were smaller than those of hexagonal boron-nitride (h-BN). The π + σ plasmon energy is explained by the surface plasmon excitation. Dielectric functions of the BNTs were derived from the loss functions by Kramers-Kronig analysis. The bandgap energy was obtained to be ∼5 eV, which is smaller than that of h-BN of 5.8 eV, from the imaginary part of the dielectric function. Full width at half maximum (FWHM) value of the 1s → π* transition peak in boron K-shell excitation spectra was nearly the same as that of h-BN, whereas the FWHM value of the peak of carbon nanotubes was greater than that of graphite. No additional broadening of the peaks of the BNTs may be attributed to a weak interaction between the pz orbitals of adjacent boron and nitrogen atoms.

Effort to produce textured CeO<sub>2</sub>and MgO films by the spray pyrolysis technique as buffer layers for coated conductors (2008)

The possibility of using spray pyrolysis as a simple, chemical, low cost method for the production of CeO2 and MgO thin films widely used as buffer layers for second generation coated conductors was examined. CeO2 films were produced on borosilicate glass substrates and four different surface morphologies were observed at different deposition temperatures. The smoothest films were obtained when the process was described as low temperature chemical vapour deposition. In addition, c-axis textured CeO2 films have been deposited on Si (100) single crystal, but the surface morphology was quite rough, consisting of distinct particles indicating that further optimisation is needed. On the other hand c-axis textured MgO films with smooth morphologies were deposited on Si (100) single crystal. Rocking curves revealed an excellent out of plane texture with a FWHM between 0.950 and 1.010
A Primer for Using Transgenic Insecticidal Cotton in Developing Countries (2009)

Many developing countries face the decision of whether to approve the testing and commercial use of insecticidal transgenic cotton and the task of developing adequate regulations for its use. In this review, we outline concepts and provide information to assist farmers, regulators and scientists in making decisions concerning this technology. We address seven critical topics: 1) molecular and breeding techniques used for the development of transgenic cotton cultivars, 2) properties of transgenic cotton cultivars and their efficacy against major insect pests, 3) agronomic performance of transgenic cotton in developing countries, 4) factors affecting transgene expression, 5) impact of gene flow between transgenic and non-transgenic cotton, 6) non-target effects of transgenic cotton, and 7) management of pest resistance to transgenic cotton.
Optimal Multi-View Fusion of Object Locations (2008)

In surveillance applications, it is common to have multiple cameras observing targets exhibiting motion on a ground plane. Tracking and estimation of the location of a target on the plane becomes an important inference problem. In this paper, we study the problem of combining estimates of location obtained from multiple cameras. We model the relation between the uncertainty in the location estimation to the position and location of the camera with respect to the plane (which is encoded by a 2D projective transformation). This is addressed by a theoretical study of the properties of a random variable under a projective transformation and analysis of the geometric setting when the moments of the transformed random variable exist. In this context, we prove that ground plane tracking near the horizon line is often inaccurate. Using suitable approximations to compute the moments, a minimum variance estimator is designed to fuse the multi-camera location estimates. Finally, we present experimental results that illustrate the importance of such modeling in location estimation and tracking.

Nitric oxide prodrugs and metallochemotherapeutics: JS-K and CB-3-100 enhance arsenic and cisplatin cytolethality by increasing cellular accumulation (2004)

Development of chemotherapeutic resistance is a major cause of pharmacologic failure in cancer treatment. One mechanism of resistance in tumor cells is the overexpression of glutathione S-transferases (GSTs) that serve two distinct roles in the development of drug resistance via the formation of glutathione conjugates with drugs for their cellular efflux, and the inhibition of the mitogen-activated protein kinase pathway. To target GST-based resistance to chemotherapeutics, a series of nitric oxide (NO)-releasing diazeniumdiolates was synthesized and shown to release NO on reaction with GST and/or glutathione. Two diazeniumdiolates, JS-K [O(2)-(2,4-dinitrophenyl) 1-[(4-ethoxycarbonyl)piperazin-1-yl]diazen-1-ium-1,2-diolate] and CB-3-100 [O(2)-(2,4-dinitrophenyl) 1-[4-(N,N-diethylcarboxamido)piperazin-1-yl]diazen-1-ium-1,2-diolate], were studied on their ability in reversing arsenic and cisplatin resistance in a rat liver cell line that is tumorigenic and shows acquired tolerance to arsenic and cisplatin, with overexpression of GSTs. The enhanced cytolethality produced by the NO donors was accompanied by increased accumulation of arsenic and platinum within cells and by enhanced activation of mitogen-activated protein kinase members c-jun-NH-kinase and extracellular signal-regulated kinase. Our data indicate that JS-K and CB-3-100 are promising lead compounds for the possible development of a novel class of adjuvant chemotherapeutic agents potentially capable of reversing arsenic and cisplatin resistance in certain tumor cells.
Effects of antithrombin III on glomerulonephritis induced by antibasement membrane antibody in rats. (1990)

Antithrombin III (AT III), a plasma inhibitor of coagulation factors, was evaluated for its inhibitory effects on the development of glomerulonephritis induced by antibasement membrane antibody in rats. AT III was administered intravenously at 250 and 1000 Units/kg to rats once a day for 14 days after intravenous injection of rabbit antiserum against the rat glomerular basement membrane. In the rat model, the high dose of AT III reduced the urinary total protein, plasma total cholesterol and plasma phospholipid, and tended to lower the incidence of fibrin deposits in Bowman's space, cell proliferation in the glomeruli, and PAS-positive granules (absorption droplets) in the glomerular epithelium. The above results suggest that AT III is effective in inhibiting the development of glomerulonephritis.
Formation and Evolution of Chemical Gradients and Potential Differences Across Self‐Assembling Inorganic Membranes (2012)

Silica gardens are well-known examples for the self-assembly of inorganic material (see figure). The growth of hollow tubes results in the spontaneous formation of two compartments with highly dissimilar pH and ion concentrations, which cause electrochemical potential differences across the membrane. Initially generated gradients are relieved over time through dynamic diffusion and precipitation processes.
A Two-Range System for Ex-Core Neutron Flux Monitoring (1970)

In a reactor supplied power generating plant, one of the means conventionally used to monitor reactor power is a neutron flux monitoring system. The pressurized-water-reactor instrumentation systems have included ex-core neutron (leakage neutrons) monitors and have traditionally used three-range systems. The three ranges have been required because the flux values covered approximately 11 decades and the dynamic range of the available instruments was limited. The C-E neutron flux monitoring system applies the concept of wide and narrow range (two groups of instruments) monitoring of the neutron flux instead of using three ranges or groups of instruments. The system uses a total of ten channels which are subdivided into four wide-range logarithmic channels monitoring the neutron flux from source level to full reactor power level, and six linear power range channels monitoring the neutron flux from approximately 0.1 percent to full reactor power level. The four wide-range channels operate from a combination of proportional counters and fission chambers. A single output signal from each channel is produced by pulse counting techniques for the first five decades of flux values, and by mean square variation techniques up to full reactor power. This method reduces errors due to gamma background as well as resolution counting loss errors normally associated with high rate counting. The four wide-range logarithmic channels provide rate-of-change-of-power information to four reactor protective channels. The narrow (linear power) range channels operate from dual-section uncompensated ionization chambers, each section covering one half (axially) of the reactor core.

Numerical Simulations of Leakage from Underground LPG Storage Caverns (2004)

To secure a stable supply of petroleum gas, underground storage caverns for liquified petroleum gas (LPG) are commonly used in many countries worldwide. Storing LPG in underground caverns requires that the surrounding rock mass remain saturated with groundwater and that the water pressure be higher than the liquid pressure inside the cavern. In previous studies, gas containment criteria for underground gas storage based on hydraulic gradient and pressure have been discussed, but these studies do not consider the physicochemical characteristics and behavior of LPG such as vaporization and dissolution in groundwater. Therefore, while these studies are very useful for designing storage caverns, they do not provide better understanding of the either the environmental effects of gas contamination or the behavior of vaporized LPG. In this study, we have performed three-phase fluid flow simulations of gas leakage from underground LPG storage caverns, using the multiphase multicomponent nonisothermal simulator TMVOC (Pruess and Battistelli, 2002), which is capable of solving the three-phase nonisothermal flow of water, gas, and a multicomponent mixture of volatile organic chemicals (VOCs) in multidimensional heterogeneous porous media. A two-dimensional cross-sectional model resembling an actual underground LPG facility in Japan was developed, and gas leakage phenomena were simulated for three different permeability models: (1) a homogeneous model, (2) a single-fault model, and (3) a heterogeneous model. In addition, the behavior of stored LPG was studied for the special case of a water curtain suddenly losing its function because of operational problems, or because of long-term effects such as clogging of boreholes. The results of the study indicate the following: (1) The water curtain system is a very powerful means for preventing gas leakage from underground storage facilities. By operating with appropriate pressure and layout, gas containment can be ensured. (2) However , in highly heterogeneous media such as fractured rock and fault zones, local flow paths within which the gas containment criterion is not satisfied could be formed. To eliminate such zones, treatments such as pre/post grouting or an additional installment of water-curtain boreholes are essential. (3) Along highly conductive features such as faults, even partially saturated zones possess certain effects that can retard or prevent gas leakage, while a fully unsaturated fault connected to the storage cavern can quickly cause a gas blowout. This possibility strongly suggests that ensuring water saturation of the rock surrounding the cavern is a very important requirement. (4) Even if an accident should suddenly impair the water curtain, the gas plume does not quickly penetrate the ground surface. In these simulations, the plume takes several months to reach the ground surface.
Thermal Release and Catalytic Removal of Organic Sulfur Compounds from Upper Freeport Coal (2005)

The tetrahydrofuran/carbon disulfide (THF/CS2) mixed solvent-insoluble portion of Upper Freeport coal was subject to noncatalytic and nickel-catalyzed hydrothermal treatments under pressurized hydrogen at 300 °C. The petroleum ether (PE)-soluble fractions from the reaction mixtures were analyzed using gas chromatography (GC) and gas chromatography/mass spectroscopy (GC/MS). Twenty-two organic sulfur compounds (OSCs) were detected in the PE-soluble fraction from the reaction mixture of noncatalytic hydrothermal treatment, whereas only very small amounts of two OSCs were detected in the PE-soluble fraction from the reaction mixture of nickel-catalyzed hydrothermal treatment, suggesting that the thermally released OSCs from the insoluble portion were effectively removed by the nickel catalyst. The related mechanisms were discussed.
Autoinducer-2-Producing Protein LuxS, a Novel Salt- and Chloride-Induced Protein in the Moderately Halophilic Bacterium <i>Halobacillus halophilus</i> (2007)

The moderately halophilic bacterium Halobacillus halophilus carries a homologue of LuxS, a protein involved in the activated methyl cycle and the production of autoinducer-2, which mediates quorum sensing between certain species. luxS of H. halophilus is part of an operon that encodes an S-adenosylmethionine-dependent methyltransferase, a cysteine synthase, and a beta-cystathionine lyase. Expression of luxS was growth phase dependent, with maximal expression in the mid-exponential growth phase. In addition, transcription of luxS was strictly salt dependent; maximal mRNA concentrations were observed with 2.0 M NaCl in the growth medium. Chloride ions stimulated luxS transcription by a factor of three. Western blot analyses demonstrated a growth phase- and salinity-dependent production of LuxS. Moreover, cellular LuxS levels were strictly chloride dependent. Maximal accumulation of LuxS was observed at 0.5 to 1.0 M Cl(-) and depended on the salinity.
Some aspects of the wideband recording of the electrocardiogram (1990)

The physiological mechanisms responsible for the high frequency components of the electrocardiographic signals in different frequency ranges are still unknown. These components have been studied in the frequency domain as well as in the time domain. Numerous clinical and experimental studies have focused upon the incidence and interpretation of high frequency notches and slurs under different conditions in the myocardium. However, the analysis of the high frequency components appeared to be tedious and imprecise, and the interpretation of its results difficult and controversial, and strongly dependent upon empirically determined standards which still require thorough evaluation. Digital methods for processing electrocardiographic signals developed during the last decade have given rise to a variety of fast and reliable approaches for analyzing the information carried by the electrocardiogram. Many researchers have applied such methods to various clinical situations in human studies and to different kinds of interventions in animal studies. These developments prompted us to review research in the field of wideband recording of the electrocardiogram and to briefly discuss some of the aspects that still require elucidation.
Origins of heart rate variability: autonomic blockade of large magnitude, transient bradycardia in conscious rabbits. (2001)

LMTBs are similar to alerting responses; they are both expressed as transient hypotensive and bradycardic events that are markedly reduced by muscarinic and alpha1-adrenoceptor blockade but not by beta-adrenoceptor blockade. The presence of LMTBs may indicate ongoing, subtle changes in the laboratory environment.

New approach to low emission of nitric oxides from furnaces using highly pre-heated air combustion (2000)

Heat-recirculating combustion by regeneration produces high-temperature flames and emission of nitric oxides increases with the flame temperature. This is the main reason why reduction of nitric oxides is essential to give the high thermal efficiency of regenerative combustion systems. However, in this work, combustion takes place even though the combustion air is diluted with burnt gases until its oxygen concentration becomes as low as 1 or 2% by use of combustion air pre-heated to a temperature higher than the auto-ignition temperature of the fuel. These unexpected conditions were used to reduce the emission of nitric oxides because the associated temperature rise due to combustion was considered relatively small. Thus, innovative combustion technology, in which both high thermal efficiency and low nitric oxides emission can be achieved simultaneously, is possible.
Semi - Autonomous Olfactive Environment Inspection by a Mobile Robot (2005)

Mobile robots can be of great value in the automated monitoring of chemical warehouses and industrial sites to prevent hazardous fluid leakages, thus increasing the safety level for human operators. This paper describes recent and current research at the University of Lecce aiming at developing a mobile platform with olfactory capability for hazardous site monitoring. An innovative smart transducer array of tin oxide chemical sensors, compliant with the standard interface IEEE 1451, is introduced and integrated on a differential drive mobile robot. A two stage strategy for environment inspection is proposed: first the vehicle is remotely controlled along a desired path (path learning phase), then the robot autonomously re-runs the path while recording in real time olfactory data of the environment. Experimental results relative to our laboratory environment are described
