Adsorption of copper, zinc, and cadmium on clay fraction of two acid soils: Surface complexation modeling (2001)

ABSTRACT The adsorption of copper (Cu), zinc (Zn), and cadmium (Cd) as a function of pH was studied on the clay fraction of two acid soils (Typic Rhodoxeralf and Aquic palexeralf), in two ionic strengths and two different metal concentrations. Specific surface area was determined by BET-N2 and EGME. The charge development on the clay surface was studied in the pH range ∼3,5 to ∼10,0 by potentiometric titration under continuous flow of argon. The least square optimization program FITEQL32, for Constant Capacitance (CCM) and the Double-Layer Model (DLM) was used to fit the titration and adsorption data, In both models surface site density was fixed at 2.31 sites/nm2, while for CCM capacitance density was set at C = 1.06. The Palexeralf soil exhibited higher specific surface area by both methods and is adsorbing all three metals in lower pH values than the Rhodoxeralf. Both clays exhibited PZSE values higher than montorilonite and kaolinite but in close approximation to the second, possibly due to higher content of iron oxides. The adsorption order for both clays was Cu > Zn > Cd in any case, thus more Cu is adsorbed at a certain pH than Zn and even more than Cd, while the increase of metal concentration or ionic strength shifts the adsorption curve towards higher pH values. CCM is describing the titration data satisfactorily by using EGME, while by using BET, alteration of Ns and C values is needed. Adsorption data are described by CCM by emphasizing the formation of monodentate surface complex. Bidentate complex in most of the cases was of no importance in describing the data despite the evident of its presence in recent spectroscopic studies for Cu and Cd ongoethtite. When BET surface area was applied better fit was achieved and bidentate complex became important in some cases for the optimization procedure. Double-layer model is exhibiting worse fit in any case.
Homeownership and Nontraditional and Subprime Mortgages (2017)

This article documents the growth and geographic distribution of nontraditional mortgages (NTMs) and subprime mortgages during 2000-2006, and examines the association between these products and homeownership at the county level between 2000 and 2012. It finds a significant relationship between the origination of NTM and subprime mortgages during the boom and changes in the number of homeowners (positive during the 2000-2006 period and negative during the 2006-2012 period) but no significant relationship with the change in the homeownership rate. Looking at specific categories of the population, the results indicate a positive relationship between the presence of NTMs and subprime mortgages and increased numbers of homeowners for young households as well as for low income and minority households, but the relationship is smaller than for the general population. Overall, the relationship between NTMs and homeownership is stronger than the relationship between subprime mortgages and homeownership during the boom and it is less negative during the bust.
Structure Determination of the Human Protective Protein: Twofold Averaging Reveals the Three-Dimensional Structure of a Domain Which was Entirely Absent in the Initial Model (1996)

Mutations in the human 'protective protein' result in the human lysosomal storage disease galactosialidosis. The structure of the human 'protective protein' has been determined using X-ray crystallography to a resolution of 2.2 A. Initial phases were obtained from molecular replacement calculations. A very partial search model comprising 30% of the scattering mass, was constructed from the atomic model of the wheat serine carboxypeptidase. This truncated probe was used to find the position of two monomers in the asymmetric unit. Subsequently, 'bootstrapping' cycles, consisting of twofold averaging and model expansion, retrieved the electron density for residues initially missing. In particular, it proved possible to add a domain (more than 110 residues) to the initial partial search model. In total, 314 residues per asymmetric unit were added to the 588 residues of the initial model. Factors contributing to our success are discussed.
Characterization of Flame-Generated TiO<sub>2</sub> Deposited Activated Carbon Fibers (ACF) (2007)

Even though activated carbon fibers (ACF) have been attractive due to high specific surface area and uniform micropore structure, there are only a few reports about the photocatalyst immobilization on ACF or their photodegradation behavior for removal of organic pollutants. In this study, ACF were selected as adsorptive support for photocatalyst immobilization. As photocatalysts, TiO2 nanoparticles were synthesized by using a N2-diluted and oxygen-enriched co-flow hydrogen diffusion flame. The visible flame length of 150mm was obtained by direct photographs. Flame temperature was measured by rapid insertion measurement technique with a R-type (Pt/Pt-13%Rd) thermocouple which was in wire shape (127μm diameter). TiO2 particles were sampled by using a high temperature particle sampler and then were coated on ACF filters. The sampling was carried out at 70mm and 110mm above the burner. The structure of TiO2 particles was analyzed by XRD. TiO2 coated ACF filters were characterized by FESEM-EDX and BET analyses. TiO2 particles on ACF filters were found to be agglomerated particles and the size of primary particles was approximately 50nm. The structure of TiO2 particle was anatase-phase crystalline structure. The specific surface area of TiO2 coated ACF filter was enhanced to be 1700~1860m2/g, depending on the sampling location, and the pores were micropores, regardless of the sampling location.

Single‐Step Spray Printing of Symmetric All‐Organic Solid‐State Batteries Based on Porous Textile Dye Electrodes (2019)

Abstract A symmetric solid‐state battery based on organic porous electrodes is fabricated using scalable spray‐printing. The active electrode material is based on a textile dye (disperse blue 134 anthraquinone) and is capable of forming divalent cations and anions in oxidation and reduction processes. The resulting molecule can be used in both negative and positive electrode reactions. After spray printing an inter‐connected pore honeycomb electrode, a solid‐state electrolyte (σ Li : × 10 −4 S cm −1 ) based on a polymeric ionic liquid is spray‐printed as a second layer and infiltrated through the porous electrodes. A symmetric all‐organic battery is then formed with the addition of another identical set of electrode and electrolyte layers. Both density functional theory calculations and charge‐discharge profiles show that the potentials for the negative and positive electrode reactions are amongst the lowest (≈2.0 V vs Li) and the highest (≈3.5 V vs Li), respectively, for quinone‐type molecules. Over the C‐rate range 0.2 to 5 C, the battery has a discharge cell voltage of more than 1 V even up to 250 charge‐discharge cycles and capacities are in the range 50–80 mA h g −1 at 0.5 C.
Hoop/Column Antenna: RF Verification Model. Volume 1: Test Results (1984)

As part of the Large Space System Technology Program, this report, in two volumes, presents the theoretical and experimental results of the RF characteristic of a hoop/column, quad aperture antenna using an RF verification model. To satisfy the primary purposes of the model it provides experimental pattern data for the quad aperture configuration at different reflector edge illumination levels, from which the geometry and edge effects can be assessed, and provides experimental data which can be compared with calculations using various theoretical reflector scattering formulae. It also experimentally determines the effects upon secondary patterns of scale model quartz cables, as used in the hoop/column design, upon secondary patterns in order to assess the importance of developing a scattering theory to predict such effects. In addition, this report contains a comprehensive theoretical study and the experimental pattern results of quad aperture antenna feeds, a discussion of the fundamental affect of parasitic side lobes, their amplitude, and location in space.
<title>Lung imaging fluorescence endoscope: development and experimental prototype</title> (1991)

A lung imaging fluorescence endoscope has been developed which can be used for detection and localization of early lung cancer. We exploited tissue autofluorescence alone or in combination with fluorescent tumor localizing drugs to create pseudo images which can clearly delineate the diseased sites from the surrounding normal tissues. With this technique it is possible to detect early lung cancer as well as pre-cancerous lesions of one to two millimeters in diameter and only a few cell layers thick.
Series-L/parallel-tuned class-E power amplifier analysis (2005)

An analysis of the operation of a new series-L/parallel-tuned class-E amplifier and its equivalence to the classic shunt-C/series-tuned class-E amplifier are presented. The first reported closed form design equations for the series-L/parallel-tuned topology operating under ideal switching conditions are given, including the switch current and voltage in steady state, the circuit component values, the peak values of switch current and voltage and the power-output capability. Theoretical analysis is confirmed by numerical simulation for a 500 mW (27 dBm), 10% bandwidth, 5 V series-L/parallel-tuned, then, shunt-C/series-tuned class-E power amplifier, operating at 2.5 GHz. Excellent agreement between theory and simulation results is achieved.
Measurement of space charge distribution in XLPE cable using PEA system with flat electrode (2002)

The Pulsed Electro-Acoustic (PEA) method has been used for the measurement of space charge distribution in solid dielectric films or cable shape samples. However, the PEA system for cable shape samples had a curved surface electrode, which had the same radius curve to the outer radius of the sample cable. Therefore, if we measure cables of various radii, it is necessary to make the curved surface electrode which fits with each outer radius of various cables. In the newly developed system, we succeed in reducing the noise level and increasing the sensitivity. This improvement makes it possible to use the flat shape electrode. Using this new system, we can apply the PEA method to any size of cable. Using this system, space charge distribution in cross-linked polyethylene (XLPE) cables with various radii were measured. In this report, the examples of measurement results and comparison between the ordinary and improved system are presented.
Temporal predictability as a grouping cue in the perception of auditory streams (2013)

This study reports a role of temporal regularity on the perception of auditory streams. Listeners were presented with two-tone sequences in an A-B-A-B rhythm that was either regular or had a controlled amount of temporal jitter added independently to each of the B tones. Subjects were asked to report whether they perceived one or two streams. The percentage of trials in which two streams were reported substantially and significantly increased with increasing amounts of temporal jitter. This suggests that temporal predictability may serve as a binding cue during auditory scene analysis.
A Domain Engineering Approach to Increase Productivity in the Development of a Service for Changes Notification of the Configuration Management Database (2013)

This paper presents a domain engineering approach to build a software product line that supports the change notification service in a Configuration Management Database (CMDB) according to the Information Technology Infrastructure Library (ITIL) best practices. For the development of this product line, the proposed approach makes use of a construction of products methodology by analogy: this is a new notation which reports the variability of the products, obtaining metrics as important as the number of products and uses a language that enables, by means of the flexibilization of a product and the development of some generators, to build the rest of the product line. In addition the paper offers a standard for the analysis and design of the CMDB as well. Finally, the paper presents an economic model for the product line, where the profitability and productivity of the proposed solution are analyzed.

Ferromagnetic transition-metal-doped tin dioxide thin films (2005)

Induced ferromagnetism (FM) above room temperature in Cr/Ni/V-doped SnO/sub 2/ thin films was studied. 200 nm-thick films were grown using pulsed laser deposition technique. Structural study, magnetization measurements and chemical composition determination were done through X-ray diffraction, magnetic force microscopy at room temperature and Rutherford backscattering spectroscopy. Findings prove that doping a small amount of transition metal in nonmagnetic oxides could introduce FM thru Ruderman, Kittel, Kasuya, and Yoshida (RKKY) interaction.
ALT-I pump limiter experiments with ICRF heating on TEXTOR. Revision (1986)

To investigate the possible role of nonbilayer phases in the modulation of glycosyltransferase activity, bovine milk D-galactosyltransferase has been studied in phosphatidylethanolamine (PE) membranes, including soybean PE, egg PE, PE prepared by transphosphatidylation of egg PC, bovine brain PE, plasmalogen PE, and DPPE. The gel-to-liquid crystalline transition (TC) and the lamellar-to-hexagonal transitions (TH) are known for most of the PE compounds. The lower the TC (or TH) value, the greater the stimulation of galactosyltransferase activity in both the lactose- and N-acetyllactosamine-synthetase reactions. No correlation was found between either TC or TH value and the break in the Arrhenius plots for the N-acetyllactosamine synthetase. In membranes consisting of mixtures of PE with PC, the dominant effect was that of PC. The stimulation of activity in the mixed-lipid systems was never greater than that produced by PC alone, therefore the enzyme showed a definite preference for PC in the mixtures.
Designing III-V multijunction solar cells on silicon (2014)

Single junction Si solar cells dominate photovoltaics but are close to their efficiency limits. This paper presents ideal limiting efficiencies for tandem and triple junction multijunction solar cells featuring a Si subcell also serving as substrate. Subject to this Si bandgap constraint, we design optimum cell structures that we show depart from the unconstrained ideal. In order to progress to manufacturable designs, the use of III–V materials is considered, using a novel growth method capable of yielding low defect density III–V layers on Si. In order to evaluate the real potential of these proposed multijunction designs, a quantitative model is presented, the strength of which is the joint modelling of external quantum efficiency and current–voltage characteristics using the same parameters. The method yields a single-parameter fit in terms of the Shockley–Read–Hall lifetime. This model is validated by fitting experimental data of external quantum efficiency, dark current and conversion efficiency of world record tandem and triple junction cells under terrestrial solar spectra without concentration. We apply this quantitative model to the design of tandem and triple junction solar cells, yielding cell designs capable of reaching efficiencies without concentration of 32% for the best tandem cell and 36% for the best triple junction cell. This demonstrates that efficiencies within a few per cent of world records are realistically achievable without the use of concentrating optics, with growth methods being developed for multijunction cells combining III–V and Si materials.

Association betweenDentitheca habereri(Cnidaria: Hydrozoa) and two zoanthids (2010)

Dentitheca habereri is a leptomedusan hydroid forming large colonies on the fringing reefs of the Bunaken National Park (North Sulawesi, Indonesia). The hydroid is generally associated with two zoanthid species, Parazoanthus gracilis and Parazoanthus sp. Colonies lacking zoanthid epibionts are rare and generally smaller (8–10 cm). When associated with Parazoanthus sp., the hydroid colonies are fan‐shaped and may exceed 1 m in width. In contrast, when D. habereri is colonised by the large polyps of Parazoanthus gracilis, the host colonies are smaller and the branching is irregular.
Positive residues involved in the voltage‐gating of the mitochondrial porin‐channel are localized in the external moiety of the pore (1990)

The role of positive charges located on the hydrophilic surface of the mitochondrial outer membrane channel was investigated by studying the interaction between LDAO-solubilized porin and a cation-exchanger column. The binding of porin to the column material was inhibited when the elution buffer had a pH of 9 or when 2 mM dextran sulfate was added to the buffer at neutral pH. Interestingly, the addition of a synthetic copolymer of methacrylate, maleate and styrene known as a potent modulator of the voltage-dependence, did not influence the interaction between column material and porin. Incubation of porin with fluorescein isothiocyanate (FITC) resulted in the isolation of a porin fraction in which on average two lysines located on the surface of the pore-forming complex per 35 kDa polypeptide were modified. The voltage-dependence of the fluorescein isothiocyanate modified porin was strongly decreased as compared with the unmodified porin. The experiments presented here give the first biochemical evidence that positively charged lysine residues located on the surface of the channel-forming complex are responsible for the gating of the mitochondrial porin-channel.

Neural activity of the cardiac baroreflex decreases with age in normotensive and hypertensive subjects (2005)

The analysis of low-frequency fluctuations in the carotid artery diameter demonstrates that aging as well as hypertension are associated with impaired neural control of the baroreflex. Beyond 50 years of age the effect of hypertension cannot be distinguished from the effect of aging.
Metabolism of proline in a human leukemic lymphoblastoid cell line. (1978)

Amino acid analysis of the culture medium was carried out in a human leukemic lymphoblastoid cell line (REH) established from the lymphoblasts of a patient with acute lymphoid leukemia. The results are compared with those of a reference cell line (LHN13) established from normal human lymphocytes. The most striking difference between these two cell lines concerns proline. In LHN13 the concentration of this amino acid in the culture medium increases by 40 microgram/ml/10(6) cells during a 72-hr incubation. In REH there is a decrease under the same culture conditions. In both cell lines proline is derived from glutamic acid and from arginine, as found with the use of 14C-labeled precursors. Synthesis of proline in the REH line represents approximately 26% of the value measured in LHN13 when the precursor is glutamic acid and 15% when the precursor is arginine. The radioisotopic assay for delta1-pyrroline-5-carboxylate reductase showed that there is a deficiency of this enzyme in the REH cells. The defect in proline synthesis of REH was found at the establishment of this line and constitutes a metabolic marker that has persisted for more than 2 years.
SAHAD: Subgraph Analysis in Massive Networks Using Hadoop (2012)

Relational sub graph analysis, e.g. finding labeled sub graphs in a network, which are isomorphic to a template, is a key problem in many graph related applications. It is computationally challenging for large networks and complex templates. In this paper, we develop SAHAD, an algorithm for relational sub graph analysis using Hadoop, in which the sub graph is in the form of a tree. SAHAD is able to solve a variety of problems closely related with sub graph isomorphism, including counting labeled/unlabeled sub graphs, finding supervised motifs, and computing graph let frequency distribution. We prove that the worst case work complexity for SAHAD is asymptotically very close to that of the best sequential algorithm. On a mid-size cluster with about 40 compute nodes, SAHAD scales to networks with up to 9 million nodes and a quarter billion edges, and templates with up to 12 nodes. To the best of our knowledge, SAHAD is the first such Hadoop based subgraph/subtree analysis algorithm, and performs significantly better than prior approaches for very large graphs and templates. Another unique aspect is that SAHAD is also amenable to running quite easily on Amazon EC2, without needs for any system level optimization.
Acute and chronic effects of self-expanding nitinol stents in porcine coronary arteries (1997)

This study shows that the CardioCoil self-expanding nitinol coil stent, is associated with favorable deployment characteristics and patency rates, although appropriate sizing is more crucial than with balloon-expandable stents. More importantly, there appears to be a "dissociation' between the deep vessel wall injury by the chronic strut expansion process and the neointimal reaction, unlike balloon-expandable stents.
Advances in rare cell isolation: an optimization and evaluation study (2017)

Our assay facilitates high performance at shortest assay time. The enrichment assay itself causes minor harm to cells and allows proliferation. Our findings suggest that rare cell contamination is unavoidable. An unexpected high variety of CD45 negative cells have been detected. It is hypothesized that a rare cell profile may translate into tumor marker independent screening.
