Remediation of contaminated soils and sludges by green plants (1995)

The potential of green plants to remove, contain, or render harmless contaminants in soils and sludges is actively being explored in an increasing number of laboratories throughout the world. This approach, which has been termed phytoremediation, exploits plants, soil amendments, and plant-associated microbiota to remediate contaminated soils. As an in situ stabilization technique, soil amendment with fertilizers, biosolids, or certain industrial by-products alters the chemical and physical nature of the contaminant in the soil matrix, thus reducing its available to biological processes. The site is then vegetated with plants that can (1) grow in the resulting soil matrix; (2) reduce leaching through the soil profile by absorbing, sequestering, or degrading residual contaminants in the soil solution; and (3) minimize wind and rain erosion. The process is known as phytostabilization, or simply site stabilization, and borrows heavily on mine reclamation techniques. As a site decontamination technique, the soil is treated to increase the availability of the contaminant to biological processes and then planted with plants that (1) accumulate the contaminant and are harvested for further pollutant destruction, sequestration, or reclamation or (2) use plant or plant-associated microbial processes to destroy the pollutant in situ.

High speed primitives of hardware accelerators for DSP in GaAs technology (1992)

The EUROCHIP initiative is providing foundry, access and full support for a variety of technologies including CMOS and BiCMOS. At present, a GaAs foundry has been selected for high-frequency analogue design (MMIC), and some wafers have been processed. However no foundry runs have yet been selected for GaAs digital circuits. A number of European design laboratories are looking forward to that possibility. Certainly there are not many European foundries with suitable processing. Meanwhile, access to GaAs foundries has been set up by an international university consortium. In particular, this work has been done under the research program in GaAs digital circuits design set up by the Centro de Microelectronica Aplicada, of the University of Las Palmas, in collaboration with the Centre for Gallium Arsenide VLSI Technology, University of Adelaide, and the Middlesex Polytechnic of London. We hope that, in the future, EUROCHIP can support this technology. The paper describes work to design a set of basic computational primitives in digital signal processing (DSP) such as registers, adders and multipliers, and explores the influence of layout and design methodology on the performance of these cells. They have been developed using a design and buffering technique, and symbolic layout notation, well suited for robust design in GaAs DCFL logic. The results obtained so far show that they represent a good compromise between speed, area, and power for VLSI circuits.
The TPS development of parallel automatic test systems (2005)

With current generation and next generation test systems focusing on testing efficiency, it is critical to develop test strategies that maximize testing throughput, make better use of the increasingly expensive instruments used in test station and drive down test costs. Parallel test, which means multiple units-under-test (UUTs) can undergo testing simultaneously, improves testing strategy by enhancing product flow, reducing aggregate test times, and improving instrument usage. The research and development of parallel automatic test systems (PATS) discussed in this paper is on the basis of common automatic test systems (CATS). Under the condition that PATS possesses all testing resources of CATS, how to make better use of instruments to increase throughput and cut down testing costs? The TPS (test program set) development of PATS is regarded as the key in this paper. The main tasks of the TPS development of PATS include the following four themes. The first is how to analyze test requirements. The second is how to design test unit adapter supporting parallel test. The third is to design and develop test program supporting multiple tasks and threads, which is the core of PATS. The last theme is how to manage multiple tests of PATS. We use the COTS software-TestStandTM to manage parallel testing tasks easily. In the paper, the development and management procedure of PATS's TPS is discussed in detail based on the TPS development of missiles PATS.
SPEC as a performance evaluation measure (1995)

Potential computer system users or buyers usually employ a computer performance evaluation technique only if they believe its results provide valuable information. System Performance Evaluation Cooperative (SPEC) measures are perceived to provide such information and are therefore the ones most commonly used. SPEC measures are designed to evaluate the performance of engineering and scientific workstations, personal vector computers, and even minicomputers and superminicomputers. Along with the Transaction Processing Council (TPC) measures for database I/O performance, they have become de facto industry standards, but do SPEC's evaluation outcomes actually provide added information value? In this article, we examine these measures by considering their structure, advantages and disadvantages. We use two criteria in our examination: are the programs used in the SPEC suite properly blended to reflect a representative mix of different applications, and are they properly synthesized so that the aggregate measures correctly rank computers by performance? We conclude that many programs in the SPEC suites are superfluous; the benchmark size can be reduced by more than 50%. The way the measure is calculated may cause distortion. Substituting the harmonic mean for the geometric mean used by SPEC roughly preserves the measure, while giving better consistency. SPEC measures reflect the performance of the CPU rather than the entire system. Therefore, they might be inaccurate in ranking an entire system. To remedy these problems, we propose a revised methodology for obtaining SPEC measures.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Importance of the third thrombospondin repeat of C6 for terminal complement complex assembly. (1995)

The anti-C6 monoclonal antibody WU 6-4 was shown to be unequivocally native restricted since it neither binds to the terminal complement complex (TCC) nor to C5b6. In addition, it was shown to inhibit TCC formation by interfering with C5b6 generation. Using the pUEX expression system and C6 cDNA the WU 6-4 epitope was mapped to the third thrombospondin repeat of C6. This protein domain may therefore contribute to the C5 binding site of C6 and be involved in terminal complement complex assembly. The presence of the epitope in rabbit C6 indicates a useful model for studying inhibition of TCC formation in vivo.

Preparation of Pure Plasmid or Cosmid DNA Using Single-Strand Affinity Matrix and Gel-Filtration Spin Columns (1996)

A rapid method has been developed for ultrapure plasmid or cosmid DNA isolation from ten-mL to several hundred-mL cultures of Escherichia coli (midi to maxi prep). A cleared lysate is prepared by alkaline lysis, followed by a quick alcohol precipitation step. Denatured bacterial DNA and RNA having at least 20 nucleotides of single-stranded regions are removed from the supercoiled plasmid by binding strongly to the single-strand affinity matrix (SSAMTM). Plasmid DNA is then effectively purified on a gel-filtration spin column to remove SSAM, proteins, small RNA and salts. This method produces consistent yields of high-quality plasmids that are suitable for use in many molecular biology applications. In addition, recombinant cosmids of approximately 46 kb can be purified intact, free of chromosomal DNA.
Structured Design Implementation - A Strategy for Implementing Regular Datapaths on FPGAs (1996)

SDI is a strategy for the efficient implementation of regular datapaths with fixed topology on FPGAs. It employs parametric module generators, a floorplanner based on a genetic algorithm, and a circuit compaction phase through local technology mapping and placement by ILP models. Initial results promise faster layouts than with general algorithms.
Maternal asthma, premature birth, and the risk of respiratory morbidity in schoolchildren in Merseyside. (1995)

Maternal smoking during pregnancy and maternal asthma are independent risk factors associated with preterm delivery. Asthma in mothers predisposes to preterm delivery but not fetal growth retardation. Preterm birth, but not growth retardation, predisposes the child to the development of subsequent asthma.
An overview of hormone-associated cancers. (1978)

Data on the etiology of hormone-associated cancers are reviewed. Although for breast cancer many risk factors point to the relevance of hormonal factors, findings are not uniform. Evidence points to the importance of dietary factors, and one study appears to confirm an association with high total fat intake. Dietary factors, although possibly mediated through a hormonal mechanism, may eventually be found to play a major role in the etiology of breast cancer. Studies of both endometrial and ovarian cancer also show the importance of hormonally associated factors, although not always in the same way as for breast cancer. In addition, both for these sites and for cancer of the prostate, dietary factors may also be relevant in their etiology. As yet, no direct assessment of the importance of diet has been attempted for these sites, but this could be rewarding.
Symbolical singular value decomposition for a 7-DOF manipulator and its application to robot control (2002)

The method for symbolical singular value decomposition (SVD) based on Jacobian decomposition is broadened to cover simple redundant manipulators. The redundant robot should be decomposed into its nonredundant part and an actually redundant subrobot. The Jacobians should be expressed in some intermediate coordinate frames in order to obtain the simplest symbolical expressions. The Jacobian for the nonredundant part should be decomposed into several submatrices of the order 1*1, 2*2 or 3*3. In the case of 3*3 matrices, it is not always possible to obtain the symbolical expressions for SVD. The redundant subrobot Jacobian should also be further decomposed into submatrices of the order m/sub s/*n/sub s/, with m/sub s/ being less or equal to 2. By deriving the symbolical damped least-squares solution, the numerical complexity is reduced about 15 times as compared to the numerical SVD of the Jacobian submatrices of the same order. Simulations at the kinematic control level have shown very low position error and limited joint velocities.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Communication: Padé spectrum decomposition of Fermi function and Bose function (2010)

Padé approximant is exploited for an efficient sum-over-poles decomposition of Fermi and Bose functions. The resulting poles are all pure imaginary and can therefore be used to define Padé frequencies, in analogy with the celebrated Matsubara frequencies. The proposed Padé spectrum decomposition is shown to be equivalent to a truncated continued fraction. It converges significantly faster than other schemes such as the Matsubara expansion at all temperatures. By introducing the characteristic validity length as the measure of approximant, we analyze the convergence properties of different schemes thoroughly. Our results qualify the present scheme the best among all sum-over-poles approaches. Thus, it is of great value in efficient numerical evaluations of integrals involving Fermi/Bose function in various condensed-phase matter problems.
State of the art of DC components for secondary power distribution of Space Station Freedom (1991)

120 V DC secondary power distribution has been selected for Space Station Freedom. State-of-the art components and subsystems are examined in terms of performance, size, and topology. One of the objectives of this work is to inform the users of Space Station Freedom what is available in power supplies and power control devices. The other objective is to stimulate interest in the component industry so that more focused product development can be started. Based on results of this study, it is estimated that, with some redesign, modifications, and space qualification, many of these components may be applied to Space Station Freedom needs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Back-contacted emitter GaAs solar cells (1990)

A new device structure to improve the performance of concentrator GaAs solar cells is described and the first experimental results are reported. The reason for such an improvement relies on a drastic reduction of the shadowing and series resistance losses based on the possibility of back contacting the emitter region of the solar cell. The experimental results obtained with devices of these types, with a simplified structure, fabricated by liquid phase epitaxy, demonstrate the feasibility and correct operation of the proposed back contact of the emitter of the cells.
Complementary reciprocity theorems for two-port networks and transmission lines (1994)

Two complementary reciprocity theorems have been formulated in this work; one for two-port passive networks and another for transmission lines. The theorems involve two networks or two identical sections of lines with different load impedances that must satisfy a complementary impedance condition relating to the characteristic impedances of the network or the characteristic impedance of a line.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Metabolism of small peptides in rumen fluid. Accumulation of intermediates during hydrolysis of alanine oligomers, and comparison of peptidolytic activities of bacteria and protozoa (1990)

Abstract Oligopeptides of L ‐alanine up to ala 5 , were incubated in vitro in either strained rumen fluid or suspensions of mixed rumen bacteria. The disappearance of substrates and formation of products were measured for 40 min, by which time ala 3 , ala 4 and ala 5 were almost totally hydrolysed. Ala 2 was more slowly hydrolysed, and accumulated in incubations with the other peptides. The pattern of formation of ala 2 but not ala 3 from ala 4 , and ala 3 and ala 2 but not ala 4 from ala 5 , suggested that the peptides were being hydrolysed by a dipeptidyl peptidase mechanism. Three different sheep receiving different diets gave similar results. Neither substrates nor products appeared to be accumulated intracellularly, except for ala 2 , and then only if protozoa were present. Protozoa were more active than bacteria in ala 2 hydrolysis, whereas bacteria had greater activities with higher homologues. Similar preferences were observed with glycine peptides, although unlike alanine peptides gly 3 and gly 5 were more slowly degraded than the dimer. These experiments suggest that protozoa are of importance in the accumulation and hydrolysis of dipeptides, whereas bacteria are responsible for the breakdown of larger molecules by a dipeptidyl peptidase mechanism that does not appear to involve accumulation within the cell.
An effective method to reduce the computing time of nonlinear time-stepping finite-element magnetic field computation (2002)

Time-stepping finite-element methods have been widely used to compute the magnetic field of electrical machines. Because the reluctivities of magnetic materials are nonlinear, the finite-element equations have to be solved iteratively. In this paper, an effective method for reducing the computing time of the Newton-Raphson method coupled with the incomplete Cholesky-conjugate gradient algorithm for solving time-stepping finite-element problems is presented. The proposed method is based on a proper prediction of some predefined error tolerances in the iteration processes at each time-stepping finite-element computation. The computational analysis on an induction motor shows that the proposed strategy can reduce the nominal computing time by as much as 50%.
A Comprehensive Thermal Management System Model for Hybrid Electric Vehicles. (2011)

This study describes the creation of efficient architecture designs of vehicle thermal man-agement system (VTMS) for hybrid electric vehicles (HEVs) by using numerical simula-tions. The objective is to develop guidelines and methodologies for the architecture de-sign of the VTMS for HEVs, which are used to improve the performance of the VTMS and the fuel economy of the vehicle. For the numerical simulations, a comprehensive model of the VTMS for HEVs which can predict the thermal response of the VTMS dur-ing transient operations is developed. The comprehensive VTMS model consists of the vehicle cooling system model and climate control system model. A vehicle powertrain model for HEVs is also developed to simulate the operating conditions of the powertrain components because the VTMS components interact with the powertrain components. Finally, the VTMS model and the vehicle powertrain model are integrated to predict thermal response of the VTMS and the fuel economy of the vehicle under various vehicle driving conditions. The comprehensive model of the VTMS for HEVs is used for the study on the architec-ture design of the VTMS for a heavy duty series hybrid electric vehicle. Integrated simu-lation is conducted using three VTMS architecture designs created based on the design guidelines developed in this study. The three architecture designs are compared based on the performance of the VTMS and the impact of the VTMS design on the fuel economy under various driving conditions. The comparison of three optional VTMS architectures shows noticeably significant differences in the parasitic power consumptions of the VTMSs and the transient temperature fluctuations of electric components depending on the architecture design. From the simulation results, it is concluded that, compared with the VTMS for the conventional vehicles, the architecture of the VTMS for the SHEV should be configured more carefully because of the additional heat source components, the complexity of component operations, and the dependency of the parasitic power con-sumption on driving modes.
Vaccination contre la bilharziose : réalités et perspectives (1999)

Les maladies parasitaires représentent à l'échelle mondiale un problème préoccupant de santé publique et d'entrave au développement des pays du tiers monde. L'approche vaccinale des maladies parasitaires a mis beaucoup de temps à prendre corps pour de multiples raisons. D'une part, les connaissances en immunologie parasitaire ont été longtemps en retard et d'autre part la multiplication de certains parasites in vitro est encore impossible. La bilharziose ou schistosomiase est une des maladies parasitaires les plus répandues. Elle est endémique dans 75 pays tropicaux et atteint au moins 200 millions d'individus par an. Elle est responsable d'environ 80 000 décès chaque année. Il n'existe à l'heure actuelle, aucun moyen chimioprophylactique et la chimiothérapie disponible ne prévient pas la réinfestation. La résistance à la chimiothérapie implique d'autres recherche de lutte contre cette parasitose. Le développement d'un vaccin efficace contre cette affection présente donc un intérêt primordial. Ainsi des progrès importants ont été faits ces dernières années et la possibilité de développer un vaccin pour l'homme peut maintenant être considérée comme sérieuse.
Chapter 4 Propane (2002)

With the vitality and economic growth of the U.S. being linked to affordable transportation, the use of fuels is beginning to play a larger role. The use alternative has been used to describe any fuel suggested for use in transportation vehicles other than gasoline or diesel. Since 1998, more than half of the petroleum the U.S. economy requires has been supplied by imports. In addition, the climatological and scientific community has warned that increasing concentrations of greenhouse gases in the atmosphere will cause global change. Alternative Fuels examines the accepted fuels, providing historical background, physical and chemical properties, production technology, and forecasts for each fuel. Alternative transportation fuels addressed include: methanol, ethanol, propane, natural gas, biodiesel, hydrogen, and electricity. Chapters include: The Argument for Alternative Fuels Methanol Ethanol Propane Natural Gas Electricity and more
ROS-mediated mechanisms of autophagy stimulation and their relevance in cancer therapy (2010)

Mounting evidence suggests that reactive oxygen species (ROS) are multifaceted signaling molecules implicated in a variety of cellular programs during physiological as well as pathological conditions. Recently, ROS produced endogenously, by deranged metabolism of cancer cells, or exogenously, by ROS-generating drugs, have been shown to promote macroautophagy, a lysosomal pathway of self-degradation with essential prosurvival functions. Several molecular aspects of the modulation of autophagy pathways by ROS have been revealed in the past years and it is now clear that these processes are mutually linked and play a crucial role in cancer progression and in response to cancer therapeutics. In this review we address the molecular mechanisms underlying the activation of autophagy pathways by ROS and focus on the role of autophagy in cancer cells responding to ROS-producing agents, which are utilized as a therapeutic modality to kill cancer cells.
