Uses of ion bombardment in thin-film deposition (1990)

Use of plasma- and ion-beam-modified surfaces and surface coatings in continually expanding in engineering disciplines. The purpose of these modifications and treatments is to impart favorable properties, such as wear resistance and lubricity, to the surfaces, while at the same time retaining the strength or toughness of the bulk materials. Energetic-ion bombardment can be used to modify the structural and chemical properties of surfaces or applied coatings. Ion-implantation has been used for many years, and recently, other surface-modification techniques, among them ion-beam mixing and ion-beam-assisted deposition, have attracted attention because they permit application of highly adherent lubricious and wear-resistant films. In this paper, ion-beam techniques are described from the viewpoint of ion-surface interactions, and some avenues for the engineering of tribological surfaces are presented. 100 refs., 4 figs.

Characteristics of Charcoal made from used Paper and Utilization as a Cultivation Material for Mushroom growing (2003)

This paper presents the changes of behavior and the characteristics of used paper carbonized at various temperatures up to 1, 000°C, and utilization of charcoal made from used paper, as a cultivation material for mushroom growing. The weight of the used paper decreased when heated, mainly in the temperature range from 250°C to 400°C. The used paper shrunk around the similar temperature. However, the temperature that shrinkage started was 20°C higher than the temperature that weight decrease started. The charcoal made from used paper had two types of pores, pores between fibers and pores in fibers. Pores between fibers were created at temperatures of less than 400°C, which was evident after the remarkable weight decreases had finished. Bulk density influenced the formation of the pore between fibers. Pore volume and pore diameter decreased with increased bulk density. Pleuroutus ostreatus was able to be cultivated on charcoal made from used paper. The occurrence of fruit bodies and the mycelial growth in the charcoal was greater in charcoal that had a low bulk density and high moisture content. Therefore, charcoal made from used paper is a good medium for cultivating various kinds of fungi.
Phase-specific high temperature creep behaviour of a pre-rafted Ni-based superalloy studied by X-ray synchrotron diffraction (2012)

The phase-specific high temperature creep behaviours of the γ and γ′ phases of a rafted Ni-based single crystal superalloy were investigated by a combination of in situ creep experiments and diffraction of high-energy X-ray synchrotron radiation. In situ experiments were performed at constant temperatures in a 930–1125 °C temperature range and under variable applied stress in order to study the material’s response (plastic strain, load transfer) to stress jumps. Using three crystal diffractometry in transmission (Laue) geometry, it was possible to measure the average lattice parameters of both the matrix and the rafts in the [1 0 0] direction at intervals shorter than 300 s. The absolute precision on the measurement of the constrained transverse mismatch (in the rafts’ plane) is better than 10−5. Plastic strain occurs within the γ corridors as soon as the Von Mises stress exceeds the Orowan stress. The plasticity of the γ′ rafts apparently depends on the transverse stress (i.e. perpendicular to the tensile axis) exceeding a threshold value of 60 MPa.
A Comparative Study of the Time-Resolved Decomposition of Methylene Blue Dye Under the Action of a Nanosecond Repetitively Pulsed DBD Plasma Jet Using Liquid Chromatography and Spectrophotometry (2013)

An underwater dielectric barrier discharge (DBD) plasma jet excited by a repetitively pulsed nanosecond pulsed power modulator was used to study plasma-induced decolorization of a 1.4 × 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-4</sup> M solution of methylene blue (MB). Past plasma decolorization studies have focused on spectrophotometry as the main diagnostic to assess decomposition. Because spectrophotometry is a measure of changes in the structure of molecular color, it is not an absolute measure of decomposition. In this paper, high-pressure liquid chromatography is used in parallel with spectrophotometry for comparison purposes and to assess the degree of true decomposition. Spectrophotometry results were found to be in agreement with chromatography measurements, suggesting that, at least in the case of MB, spectrophotometry is an adequate measure of decomposition. Additionally, the utility of a dual plasma jet applicator for rapid contaminant decomposition was explored.
D&D Knowledge Management Information Tool: A Web Based System Developed to Share D&D Knowledge Worldwide (2013)

Deactivation and decommissioning (D&D) work is a high-risk and technically challenging enterprise within the U.S. Department of Energy complex. During the past three decades, the DOE’s Office of Environmental Management has been in charge of carrying out one of the largest environmental restoration efforts in the world: the cleanup of the Manhattan Project legacy. In today’s corporate world, worker experiences and knowledge that have developed over time represent a valuable corporate asset. The ever-dynamic workplace, coupled with an aging workforce, presents corporations with the ongoing challenge of preserving work-related experiences and knowledge for cross-generational knowledge transfer to the future workforce [5]. To prevent the D&D knowledge base and expertise from being lost over time, the DOE and the Applied Research Center at Florida International University (FIU) have developed the web-based Knowledge Management Information Tool (KM-IT) to capture and maintain this valuable information in a universally available and easily accessible and usable system. The D&D KM-IT was developed in collaboration with DOE Headquarters (HQ), the Energy Facility Contractors Group (EFCOG), and the ALARA [as low as reasonably achievable] Centers at Savannah River Sites to preserve the D&D information generated and collected by the D&D community. This is an open secured system that can be accessed from https://www.dndkm.org over the web and through mobile devices at https://m.dndkm.org. This knowledge system serves as a centralized repository and provides a common interface for D&D-related activities. It also improves efficiency by reducing the need to rediscover knowledge and promotes the reuse of existing knowledge. It is a community-driven system that facilitates the gathering, analyzing, storing, and sharing of knowledge and information within the D&D community. It assists the DOE D&D community in identifying potential solutions to their problem areas by using the vast resources and knowledge base available throughout the global D&D community. The D&D KM-IT offers a mechanism to the global D&D community for searching relevant D&D information and is focused on providing a single point of access into the collective knowledge base of the D&D community within and outside of the DOE. Collecting information from subject matter specialists, it builds a knowledge repository for future reference archiving Lessons Learned, Best Practices, ALARA reports, and other relevant documents and maintains a secured collaboration platform for the global D&D community to share knowledge. With the dynamic nature and evolution of the D&D knowledge base due to multiple factors such as changes in the workforce, new technologies and methodologies, economics, and regulations, the D&D KM-IT is being developed in a phased and modular fashion.
Distributed Mechanical Parameters of Loudspeakers, Part 1: Measurements (2009)

The mechanical vibrations of loudspeaker drive units are described by a set of linear transfer functions and geometrical data which are measured at selected points on the surface of the radiator (cone, dome, diaphragm, piston, panel). These distributed parameters supplement the lumped parameters (Thiele-Small, nonlinear, thermal parameters), simplify the communication between cone, driver, and loudspeaker system design, and open new ways for loudspeaker diagnostics. This is discussed in two related papers. The first paper focuses on the laser scanning techniques and the postprocessing of the data. The mechanical vibrations can be summarized as a new quantity, called accumulated acceleration level (AAL), which is comparable to the sound pressure level (SPL) if no acoustical cancellation occurs. This and other derived parameters are the basis for modal analysis and novel decomposition techniques, which make the relationship between mechanical vibration and sound pressure output more transparent. Finally the usage of the distributed parameters within finite- and boundary-element analyses is addressed and conclusions for the loudspeaker design process are drawn.
Characterization of Grown-in Dislocations in Benzophenone Single Crystals by X-Ray Topography (1992)

Benzophenone single crystals were grown by the Czochralski method. The dislocations introduced during the crystal growth were examined using X-ray topography. Double images of single dislocations were found on the topographs taken in some reflection planes. The Burgers vector of predominant grown-in dislocations was estimated from analysis of the dislocation images on the basis of kinematical theory.

Production of fumonisins by Fusarium moniliforme strains from various substrates and geographic areas (1991)

Strains of Fusarium moniliforme from different geographic areas and from corn and other substrates were tested for the ability to produce fumonisins in culture. The test results indicate that the potential exists for production of fumonisins by such strains in agricultural commodities and other substrates in widespread geographic areas.
A 3‐Imino‐1,2‐dioxetane <i>via</i> Singlet Oxygenation of a Ketenimine (1979)

In connection with “photochemistry without light” (or chemi-energized electronic excitation) interest attaches to the 3-imino-1,2-dioxetane (1), which has been synthesized as the first representative of its class. Compound (1), is stable at low tempertature. Homolysis of the OO bond to form the elusive 1,4-dioxyl radical in heating could not be detected.
Neuronal protein gene product 9.5 (IEF SSP 6104) is expressed in cultured human MRC‐5 fibroblasts of normal origin and is strongly down‐regulated in their SV40 transformed counterparts (1991)

Neuronal protein gene product 9.5 (PGP 9.5) most likely identical to ubiquitin carboxyl-terminal hydrolase isozyme L1 (UCH-L1) has been reported to be expressed almost exclusively in neuronal and neuroendocrine tissues. By two-dimensional (2D) immunoblotting, comigration and microsequencing of proteins recovered from 2D gels we have identified PGP 9.5 UCH-L1 as polypeptide IEF SSP 6104 (Mr = 27,000, pI = 5.49) in the comprehensive 2D gel cellular protein database of human embryonal lung MRC-5 fibroblasts [(1989) Electrophoresis 10, 76 115; (1990) Electrophoresis 11, 1072 1113]. This protein is expressed at high levels in quiescent and proliferating cultured normal fibroblasts and is strongly down-regulated (about 10 times) in their transformed counterparts.
Failed Lumbar Disc Surgery Requiring Second Operation (1978)

Forty-five patients who had lumbar disc surgery 10 or more years previously, and had required a second operative procedure, have been evaluated. Failures occurred up to 16 years after the first operation, and were most commonly due to pseudoarthrosis in the patients who underwent spinal fusion initially, and to recurrent disc lesions at the same level as previous surgery in the patients who did not have fusion. The clinical and functional results in the second group of patients who required a second procedure were comparable to those of patients who required only a single procedure. In contrast, patients who had undergone spinal fusion who required a second procedure had significantly worse clinical and functional results, both in comparison to the patients who did not undergo fusion as well as to patients who had had fusion as a single procedure. The only predictable, demonstrable source of failure was acquired spondylolysis. Frequently, repair of pseudoarthrosis did not lead to symptomatic relief. These data suggest that spinal fusion, when it fails, has a significantly worse prognosis than simple disc excision in the management of lumbar disc disease.
A Flemion-based actuator with ionic liquid as solvent (2007)

A perfluorinated carboxylic acid membrane, i.e. Flemion, shows improved performance as actuator material compared with Nafion (perfluorinated sulfonic acid). Flemion has a higher ion exchange capacity and good mechanical strength. In particular, Flemion will deform with no back relaxation under applied electrical stimulus. However, with water as solvent, the operation of Flemion in air has serious problems, since water would evaporate quickly in air. Moreover, the electrochemical stability for use in water is around 1 V at room temperature. In previous work, investigations on Nafion with ionic liquid as solvents have been carried out by some researchers and good results have been obtained. In this work, we explore the use of highly stable ionic liquid instead of water as solvent in Flemion. Experimental results indicate that Flemion-based actuators with ionic liquid as solvent have improved stability as compared to the water samples. Although the forces exhibited by Flemion-based actuators with the use of ionic liquid decreased dramatically compared to water, these preliminary results suggest good potential for the use of Flemion with ionic liquid in future applications.
Estimation of Hip and Ankle Visco-Elastic Parameters During Quiet Standing (2018)

Balance control naturally deteriorates with age, so it comes as no surprise that nearly 30% of the elderly population in the United States report stability problems that lead to difficulty performing daily activities or even falling. Postural stability is an integral task to daily living which is reliant upon the control of the ankle and hip. To this end, the estimation of ankle and hip parameters in quiet standing can be a useful tool when analyzing compensatory actions aimed at maintaining postural stability. Using an analytical approach, this work builds upon the results obtained by the authors and expands it to a two degrees of freedom system where the first two modes of vibration of a standing human are considered. The physiological parameters a second-order Kelvin-Voigt model were estimated for the actuation of the ankle and hip. Estimates were obtained during quiet standing when healthy volunteers were subjected to a step-like perturbation. This paper presents the analysis of a second-order nonlinear system of differential equations representing the control of lumped muscle-tendon units at the ankle and hip. This paper utilizes motion capture measurements to obtain the estimates of the control parameters of the system. The dynamic measurements are utilized to construct a simple time-dependent regression that allows calculating the time-varying estimates of the control and body segment parameters with a single perturbation. This work represents a step forward in estimating the control parameters of human quiet standing where, usually, the analysis is either restricted to the first vibrational mode of an inverted pendulum model or the control parameters are assumed to be time-invariant. The proposed method allows for the analysis of hip related movement in the control of stability and highlights the importance of core muscle training.
Dithiocarbamate-Functionalized Dendrimers as Ligands for Metal Complexes (1998)

Zeroth- and first-generation poly(amido)amine dendrimers have been functionalized with dithiocarbamate end groups and reacted with ruthenium complexes, to form metallodendrimers. Monomeric ruthenium dithiocarbamate complexes were also prepared as model compounds and their spectroscopic data compared with those of the metallodendrimers. The novel compounds were characterized using NMR spectroscopy ((1)H and (13)C) and mass spectrometry. The compound [Ru(S(2)CNMe(2))(PPh(3))(eta(5)-C(5)H(5))] has also been characterized crystallographically.

Applying user segmentation and estimating user value in techno-economic modeling (2007)

In this article we present a holistic techno-economic framework to analyze a service delivery ecosystem and its revenue streams. In particular, we address issues related to user segmentation and pricing. The main contribution of the paper is to show that it is possible to construct and utilize analytical models to assess how users in different customer segments behave both when selecting services and when using the services. The results of the analysis provide consistent basis for service providers to design and optimize their products.

[Legionellosis in HIV-1 infected patients. 4 case reports]. (2002)

Legionella pneumophila serotype Lp1 remains the principle etiological agent. Frequent use of contrimoxazole in prophylaxis against pneumocystosis and toxoplasmosis, macrolides, rifamycines and fluoroquinolones in the preventive and curative treatment of mycobacterioses, and the relative conservation of monocyte/macrophage function and immune repair with efficient antiretroviral therapy, may explain the low prevalence of this disease in HIV infections.
Polyamine levels in pollinated and auxin‐induced fruit of tomato (<i>Lycopersicon esculentum</i>) during development (1993)

The changes taking place during fruit development in the concentration of the 3 polyamine fractions, i.e. free, perchloric acid‐soluble conjugates and perchloric acid‐insoluble bound polyamines, were analyzed in tomato fruits ( Lycopersicon esculentum Mill, cv. F121) induced to set by either pollination or auxin application. Before the onset of cell division, total polyamines were 50% higher in auxin‐treated fruits than in pollinated ones, most of the polyamines being found as perchloric acid‐soluble conjugates in both fruit set treatments. At the onset the level of polyamines in both fruit types was 100 times higher than during cell expansion or ripening. The highest polyamine found during cell division was perchloric acid‐soluble conjugated spermidine in both fruit set treatments. After cell division, polyamine concentration was similar in both fruit set treatments. The concentration of polyamines in the jelly was similar in pollinated and auxin‐induced fruits during cell expansion but not during ripening. At the onset of ripening there was an increase of one order of magnitude in the concentration of perchloric acid‐insoluble bound putrescine in the jelly of pollinated fruits. Polyamines were more than 5‐fold higher in unpollinated ovaries than in fruits induced to set by either pollination or auxins. It is suggested that pollinated and parthenocarpic fruits differ in their polyamine metabolism during the initial stages of development, but not after cell division. It is also suggested that polyamines undergo rapid turnover during cell division. Perchloric acid‐insoluble bound putrescine might play a role in seed formation in tomatoes.
