Selektive RGD-vermittelte Adhäsion von Osteoblasten an Implantat-Oberflächen (1999)

Ein klinischer Test mit dem Globo-H-Kohlenhydrat-Impfstoff (Struktur siehe Bild, KLH = keyhole limpet hemocyanin) ergab, daß dieser eine starke IgM-vermittelte Immunantwort bei Patienten mit progressivem und rezidivierendem Prostatakrebs hervorruft. Die Spezifität der Antikörper für synthetisches Globo H sowie für Globo H aus Prostata- und Brustkrebszellextrakten, die aus operativ entfernten Tumoren oder durch Biopsie gewonnen wurden, wurde durch Immun-Dünnschichtchromatographie (ITLC) nachgewiesen.
Epitaxial growth of CoSi2 layer on (100)Si and facet formation at the CoSi2/Si interface (1995)

The epitaxial nature of the CoSi2 formed on the (100)Si substrate as a result of annealing a Co/Ta bilayer at 500–1000 °C for 20 s in N2 atmosphere is described. At the early stage of annealing, diffusion of Co and Si occurs across the interlayed Ta layer, first forming a CoSi layer on the Si substrate. After that, CoSi2 grains nucleate at the CoSi/Si interface and grow laterally parallel to the surface. Due to a difference in mobility the CoSi2 grains at the interface of the CoSi/Si impede the interface movement, leading the facet formation. Even after annealing below 600 °C, the epitaxial CoSi2 grains are nucleated at the limited area of the nonepitaxial CoSi/Si interface and the faceted corner, and grow laterally along the Si surface. By increasing the annealing temperature, the epitaxiality of CoSi2 improves due to the increased lateral growth rate of the CoSi2. However, annealing above 900 °C impairs the CoSi2 crystallinity because the interlayered Ta loses its function as a diffusion barrier due to the formation of the TaSi2.
Synthesis, characterization, and evaluation of high selectivity mixed molybdenum and vanadium oxide catalysts for oxidative dehydrogenation of propane (2019)

Abstract Molybdenum and vanadium oxide catalysts with varied compositions (Mo/V = 1/1, 7/3, 8/2, and 9/1) were prepared using a modified citrate‐nitrate auto‐combustion method for the oxidative dehydrogenation of propane to propylene. These catalysts were characterized by BET‐technique, TPR, XRD, SEM, Raman, and UV spectroscopy. The effects of washing and supercritical CO 2 drying on catalysts during the preparation steps were investigated. Results show an interaction between the molybdenum and vanadium metal ions in all of these catalysts due to the presence of a peak at 785 cm −1 from the Raman study, which was assigned to a polymolybdovanadate species V‐O‐Mo vibration. This interaction could be efficient for alkane activation reaction. The catalysts were evaluated in a fixed bed micro‐reactor at temperatures in the range of 350–600 °C and at atmospheric pressure. The activity of the catalyst increased by increasing the molybdenum content. All of the catalysts in this study showed 100 % selectivity for propylene in the temperature range of 350–450 °C; however, the propylene selectivity was found to decrease with an increase in the temperature. The highest yield of 4.8 % with 100 % propylene selectivity was obtained for a catalyst with Mo/V ratio of 9:1 at 500 °C.
Monitoring the Interaction of a Single G-Protein Key Binding Site with Rhodopsin Disk Membranes upon Light Activation (2009)

Heterotrimeric G-proteins interact with their G-protein-coupled receptors (GPCRs) via key binding elements comprising the receptor-specific C-terminal segment of the alpha-subunit and the lipid anchors at the alpha-subunit N-terminus and the gamma-subunit C-terminus. Direct information about diffusion and interaction of GPCRs and their G-proteins is mandatory for an understanding of the signal transduction mechanism. By using single-particle tracking, we show that the encounters of the alpha-subunit C-terminus with the GPCR rhodopsin change after receptor activation. Slow as well as less restricted diffusion compared to the inactive state within domains 60-280 nm in length was found for the receptor-bound C-terminus, indicating short-range order in rhodopsin packing.

Systemc cosimulation and emulation of multiprocessor soc designs (2003)

SystemC is an open source C/C++ simulation environment that provides several class packages for specifying hardware blocks and communication channels. The design environment specifies software algorithmically as a set of functions embedded in abstract modules that communicate with one another and with hardware components via abstract communication channels. It enables transparent integration of instruction-set simulators and prototyping boards. The authors describe a simulation environment that targets heterogeneous multiprocessor systems. They are currently working to extend their methodology to more complex on-chip architectures.
Synthesis and preliminary analytical evaluation of the chemiluminescence from (4-[4-(dichloromethylsilanyl)-butyl]-4′-methyl-2,2′-bipyridyl)bis(2,2′-bipyridyl)ruthenium(ii) covalently bonded to silica particles (2002)

This paper describes, for the first time, a simple and effective synthetic route for covalently bonding the chemiluminescence reagent, (4-[4-(dichloromethylsilanyl)-butyl]-4'-methyl-2,2'-bipyridyl)bis(2,2'-bipyridyl)ruthenium(II) onto silica particles. The subsequent preparation of chemically regeneratable detection cells and their preliminary analytical evaluation with both sequential injection analysis and flow injection analysis are also reported. Unoptimised analytical figures of merit were established for standard solutions of codeine and sodium oxalate with detection limits calculated from three times the standard deviation of the blank signal, of 1 x 10(-8) M and 3 x 10(-7) M respectively. The chemically immobilised reagent exhibited some intriguing solvent and kinetic effects, which are also briefly discussed.
Plant Response to Engineered Metal Oxide Nanoparticles (2017)

All metal oxide nanoparticles influence the growth and development of plants. They generally enhance or reduce seed germination, shoot/root growth, biomass production and physiological and biochemical activities. Some plant species have not shown any physiological change, although significant variations in antioxidant enzyme activity and upregulation of heat shock protein have been observed. Plants have evolved antioxidant defence mechanism which involves enzymatic as well as non-enzymatic components to prevent oxidative damage and enhance plant resistance to metal oxide toxicity. The exact mechanism of plant defence against the toxicity of nanomaterials has not been fully explored. The absorption and translocation of metal oxide nanoparticles in different parts of the plant depend on their bioavailability, concentration, solubility and exposure time. Further, these nanoparticles may reach other organisms, animals and humans through food chain which may alter the entire biodiversity. This review attempts to summarize the plant response to a number of metal oxide nanoparticles and their translocation/distribution in root/shoot. The toxicity of metal oxide nanoparticles has also been considered to see if they affect the production of seeds, fruits and the plant biomass as a whole.
Integrated Modeling and Statistical Analysis of 3-D Fracture Network of the Midale Field (2008)

Abstract As the maturation of conventional oil reserves pushes the industry to explore challenging reserves, state-of-the-art reservoir characterization becomes an integral part of any exploration and production venture. Naturally fractured reservoirs are good examples of such challenging fields. Oil recovery performance estimation from such reservoirs requires a good understanding of reservoir structure and its effect on the dynamics of the process. Addressed in this work is one of the critical issues for fractured reservoirs—that is characterization and 3-D modeling of a fracture network. In this study, we employed an integrated solution by combining "direct" and "inverse" approaches to fracture network characterization in a stochastic numerical model. Static geological data obtained from cores and well logs were used together with dynamic data such as well test response to build 3-D discrete fracture network models. We utilized the data obtained from the fractured carbonate Midale field in Canada. The on-going CO2 injection project requires a reliable description of the fracture system and matrix characteristics in the field for reliable performance analysis. Fracture network constructed from static data was calibrated and validated using well test (interference drawdown and pulse) data. Matrix and several fracture parameters including fracture length, density/spacing, aperture, connectivity, and orientation were evaluated in sensitivity studies to determine which characteristics have a higher influence on the accurate match to well test response. We utilized the factorial experimental design to optimize the number of simulations needed for a sensitivity study and history match. The sensitivity analysis revealed a strong influence of matrix quality on the pressure response. Geological conditions and fracture properties specific to this field explained such distribution of matrix and fracture influence. Through this analysis we were able to clarify the role of fractures in the overall field performance. Matrix/fracture interaction was suggested to be a factor deserving attention. In a general sense, the approach used in this study proved to be useful to integrate fracture data from different sources, as well as to assess its reliability and relative importance.
Inhibition of central angiotensin responses by angiotensin type-1 receptor antibody. (1993)

Angiotensin type-1 receptor subtypes (AT1) are implicated in the physiological actions of angiotensin II in the brain. In the present study we used an AT1 receptor antibody and a polymerase chain reaction--synthesized AT1 receptor complementary DNA to show that the hypothalamus expresses significantly higher levels of AT1 receptor messenger RNA and protein compared with the brain stem. Intracerebroventricular injections of AT1-specific antibody blocks the dipsogenic and blood pressure responses induced by centrally injected angiotensin II. These results demonstrate the expression of AT1 receptor gene in the brain and that the AT1 receptor antibody is able to inhibit the physiological responses of angiotensin II mediated by the brain.
Protective system for a high‐power capacitor bank (1994)

Abstract A new protection system for capacitor banks in the case of a short‐circuiting accident is described. A pulsed power system composed of many capacitor units and closing switches is well known for producing a controlled pulse current of high power as for the power source of a plasma experimental device, etc. According to the increase of capacity of a bank system, it becomes important to protect the whole bank system from a short‐circuiting accident in a capacitor unit. Although some protective ideas have been proposed, these conventional ideas have not been sufficient to absorb the energy flowing into the failure unit from other normal units. Constructing the new 1‐MJ capacitor bank for a plasma experimental device, a newly conceived protective device is designed. The new protection system can absorb the bank energy and suppress the short‐circuiting current flowing into the failure capacitor units, and overcomes the defect in former protection systems. To confirm the utility of a new protection system, a test of a protection resistor imitating the actual bank circuit was made. The test result showed that absorbable energy for the unit ceramic resistor amounted to 1500 Joule/cc. The new system is adopted to the bank system of the TPE‐1RM15 plasma experimental device.
Slow-light photonic crystal devices for high-speed optical signal processing (2009)

This book discusses design, modeling, and the characterization of slow-light photonic crystal waveguides. Guidelines are developed to obtain slow-light waveguides with broadband characteristics and with low disorder-induced losses. Three functional devices are proposed and studied: A tunable dispersion compensator, a tunable optical delay line, and a high-speed electro-optic modulator. Optical and microwave measurements confirm the designs.
Approaches to ultrafast neutron detectors (1985)

We discuss two approaches to obtain neutron detectors of very high temporal resolution. In the first approach, a uranium-coated cathode is used in a streak tube configuration. Secondary electrons accompanying the fission fragments from a neutron-uranium reaction are accelerated, focused through a pinhole, and streaked. Calculations show that 20-ps time resolution can be obtained. In the second approach, a uranium-coated cathode is integrated into a transmission line. State-of-the-art technology indicates that a time resolution of 20 ps can be obtained by gating the cathode with a fast electric pulse.
Prediction or hydraulic performance of shell-and-tube heat exchanger: Comparison of 1D andCFD-porous media approaches (2018)

The present paper deals with Heat Exchanger sizing methods and offers a comparison between two of them: 1D global method and CFD porous media method. Following Prithiviraj et al. work [1], new developments are based on recent knowledge acquired on porous media, using a coupling strategy of a three-dimensional commercial code with an in-house code library. The distributed hydraulic resistance concept and the numerical model are briefly described and confronted with pressure drop measurements from an experimental E-type STHE setup (shell-and-tube heat exchanger) from the literature. The present paper will put into perspective capabilities and limits of each method with needs for heat exchanger rating. Flow rate repartition is calculated with CFD-porous media using Tinker’s current approach. This new analysis provides a complete comparison with 1D global method. It also reveals the major impact of leakage flow rate between baffle and tubes. The numerical estimation of pressure losses, consistent with experimental measurements of Halle et al. [2], implies that our future work will include thermal performance characterization and geometrical optimization.

Intrinsic inhomogeneity in a(La0.4Eu0.6)0.7Pb0.3MnO3single crystal: Magnetization, transport, and electron magnetic resonance studies (2006)

Conventional magnetic and transport measurements of the melt-grown mixed-valence manganite $({\mathrm{La}}_{0.4}{\mathrm{Eu}}_{0.6}{)}_{0.7}{\mathrm{Pb}}_{0.3}{\mathrm{MnO}}_{3}$ have been supplemented by a magnetic resonance study. The experimental data support the model of two magnetic phases coexisting in the crystal volume. At a temperature ${T}^{*}$, which is well above Curie temperature ${T}_{C}$, ferromagnetic clusters appear in the sample. These ferromagnetic regions possess a higher conductivity in comparison with the paramagnetic background (majority phase). On cooling through ${T}_{C}$, the magnetization of the spatially confined ferromagnetic clusters of the minority phase freezes in random directions with respect to the magnetization of the ferromagnetic majority phase due to the difference of the exchange interactions at the phase boundaries from the intraphase interactions in sign and value. Such a mixed state is responsible for the observed magnetic glassylike behavior of the system that is characteristic of inhomogeneous magnets. The fluctuations of the magnetic coupling value and sign in the sample volume are related to strong competition between the ferromagnetic and antiferromagnetic exchange interactions, which, in turn, results from the quenched disorder caused by the random chemical replacement of the perovskite $A$ site of the manganite. A phase-separation state comprised of two different ferromagnetic phases has been used to account for the colossal magnetoresistance phenomenon and the magnetic-field-driven nonlinear conduction found in the crystal.
Kinetics of Pit Growth for Stainless Steels under the Water Droplet Containing Chloride Ion (1995)

Kinetics of pit growth under the water droplet containing 0.87 to 5.79mol·kg-1 MgCl2 were studied to elucidate the atmospheric corrosion behavior of stainless steels. Pit growth rate in this test was much higher than that obtained in an actual environment. It can be assumed that pit generation and/or repassivation process was predominant factor affecting the atmospheric corrosion resistance of stainless steels.Pit volume decreased with chloride ion concentration, with chromium, nickel, and molybdenum content, and it was independent of the size of droplet. This indicates that anodic dissolution was rate-limiting, while oxygen reduction chiefly affects initiation of pits.Current density in a pit was calculated based on the variation with time of pit volume and area of the opening. Metal dissolution rate in a pit dropped considerably with time, and the current density after 400ks was around 100μA·cm-2. This was much lower than typical value required to sustain pitting (1mA·cm-2) in aqueous solution such as 0.5mol·dm-3 NaCl. Consequently, the pitting in highly concentrated solution like airborne chloride should differ from that in dilute solution.

Detection of hepatitis E virus RNA in stools and serum by reverse transcription-PCR (1996)

Stools and sera collected during an experimental hepatitis E virus (HEV) infection in monkeys and collected from humans with acute HEV infections during epidemic and sporadic cases were analyzed by reverse transcription-PCR. Two methods for RNA purification were compared. Proteinase K digestion and phenolchloroform extraction were more efficient than guanidinium isothiocyanate extraction in improving the sensitivity and specificity for the detection of HEV genomes.
Modernity and the Global “Hindoo”:The Concept of the Grand Tour in Colonial India (2008)

The ‘Grand Tour’, with its own ideological justifications, was essentially an 18th-century paradigm of travel in Europe. It referred to a journey very different from any other because it was predominantly elitist in character, and educative rather than exploratory in intention. Transposed to the imperial scenario of colonial India, however, the ‘Grand Tour’ took on a different character. In this context, this paper considers English educated ‘babu’ Bholanauth Chunder’s Travels of a Hindoo (1869) as an early attempt to formalize leisure or domestic travel. The endeavour is even more significant in a cultural environment in which the only socially sanctioned mode of travel was the pilgrimage. The paper also explores how this ‘Grand Tour’ in the context of the later 19th century enabled a visit by the colonized subject from India to Britain and London, a passage opened up by the spread of English education in the colony. This tour worked around expectations and assumptions that redefined the nature of the travel book and the character of the entries/observations made. The paradigm shift in the concept of the ‘Grand Tour’, where the observer becomes the observed, constituted a new development that challenged the primary ideology of the Tour by critiquing the very basis of the European civilizing mission. For the colonial subject, the ‘Grand Tour’ of London constituted the ambitions of the marginalized subject to critically observe the imperial rulers in the context of their own culture and learn lessons that would create an enabling socio-cultural environment for reconstituting themselves into a nation.

Demonstration of an intelligent hydrogel based diffraction grating (2005)

We report the fabrication of a diffraction grating cast into a responsive hydrogel using a silicone rubber intermediate cast from an engraved glass master grating. The aim to investigate if changes in the swelling of this gel in response to changes in the concn. of a specific analyte led to changes in the line spacing, and hence diffraction pattern, of the grating. The protocol for casting gratings was initially developed using a composite carboxymethyl dextran/bovine serum albumin gel produced using carbodiimide chem. to assess the optimum gel properties required. Examn. under a light microscope showed that, formed under appropriate synthesis conditions, CM-dextran-BSA hydrogels retained the grating structure and appeared to have similar optical properties to the silicone rubber sub-master used for casting. For a facile initial evaluation of the detection principle a no. of similar gels were produced using cross-linked alginic acid. In this case excess carboxylic groups remaining after crosslinking were able to form addnl. ionic cross-links in the presence of divalent cations (Ca2+). Test expts. with these gels showed that both the size and position of the reflected and refracted spots obtained from illumination with a Helium-Neon laser changed as gel swelling changed with calcium ion concn. i.e. the size of both diffraction and reflection spots increased as the alginate hydrogel shrank in response to changes in environmental Ca2+. The utility of the alginate based gels for the detection of cations, together with evidence that dextran protein gels can retain grating structures, suggest that this assay procedure should applicable to any hydrogel where the response is based on protein-ligand interactions. The key requirement is that the crosslinking interactions constraining gel swelling can be quant. displaced by the analyte acting as a specific competitor.
