Grid System Installation, Management and Monitoring Application (2011)

Computing Grid site administrators, responsible for the maintenance of the system must frequently deploy the operating system components and grid services on all the computers in the Grid. In case of huge Grid infrastructures with thousands of computers (nodes) manual deployment of the necessary software on every node is a laborious and time-consuming job. Therefore, administrators need an automated deployment tool that can fulfill (re)installation and (re)configuration tasks in an efficient and consistent way. This paper present an automated deployment tool developed for the maintenance of a gLite-based Grid infrastructure. In order to describe the entire software configuration and to develop a custom installation environment, we used the Puppet configuration management system. The installation is made over the network using the PXE protocol. By using this automated environment, the time needed for incident solving and reconfiguration requests was drastically reduced.
Nitriles in heterocyclic synthesis: A novel route for the synthesis of naphthodipyrans, pyridines. 2H- and 4H-Pyrans (1990)

Naphtho[2,1- b :5,6- b ']dipyrans and naphtho[1,2- b :6,5- b ']dipyrans were synthesized by the reaction of cinnamonitriles with 2,3-, 1,5-, 1,6-naphthalenediols, respectively. Polysubstituted pyridines, 2 H -pyrans and 4 H -pyrans were also synthesized from cinnamonitriles, 2-hydroxyacetophenone and 3-acetyl-4-hydroxy-1-methylcarbostyril, respectively.
Isoflavone synthase from cell suspension cultures of Pueraria lobata. (1990)

Liquiritigenin and isoliquiritigenin were converted into daidzein by a microsomal fraction of cell suspension cultures of Pueraria lobata OHWI, which had been treated with an endogenous elicitor prepared by hydrolysis of their own cell walls with a fungal endopolygalacturonase. Competitive experiments with [3H]flavanone and [14C]chalcone as the substrates for isoflavone synthase revealed that flavanone is the true substrate for this enzyme reaction and the possible role of chalcone in the reaction is excluded.
Structure and Properties of Cellulose Films Coated with Polyurethane/Benzyl Starch Semi-IPN Coating (2006)

A series of water-resistant cellulose films was prepared by coating castor oil based polyurethane (PU)/benzyl starch (BS) semi-interpenetrating polymer networks (semi-IPN). All of the coated films, with a very thin coating layer of about 0.4 μm, exhibited much better optical transmittance, water resistance, and mechanical properties than the original regenerated cellulose (RC) film, suggesting a strong interface interaction between PU/BS coating and cellulose substrate. The BS concentration in the coating had a significant effect on the properties of the coated films. With an increase of BS concentration in the coating from 10 to 70 wt %, the tensile strength and storage modulus of the coated films increased. Especially, as the tensile strength achieved a maximum value of 102 MPa, the elongation at break of the coated film still maintained a relatively higher value of 10%. Meanwhile, the coated films displayed good biodegradability, and the biodegradation rate increased with increasing BS concentration in the semi-IPN coating. Therefore, the BS component in the PU/BS coating plays an important role in the simultaneous enhancement of physical properties and biodegradability of the coated films. The good water-resistance character of the coated films could effectively extend the applying area for cellulose.
Nurses (1989)

DONALD GOULD’S book, is by and large what it claims to be, if you consider 12 chapters and the contribution of nearly 30 nurses to be a sufficient cross-section of opinion to give an insight into an entire profession.
Introduction to Volume 11: Historical and Contemporary Pressures on Children's Freedom (2005)

This volume of Sociological Studies of Children and Youth showcases the timely and important work of active, early career sociologists, who are helping to define the direction of the sub-field. Their work shares basic premises and concerns, and these underlie and provide cohesion to this diverse collection of chapters. Children and youth are active agents in their own “socialization,” producing meaning and action collaboratively with their peers, and they struggle for agency and control in various social contexts – these are the themes that, both explicitly and implicitly, shape essentially all of the contributions. The underlying concern of our own introduction above, and of many of the chapters, is that the current processes and practices may stifle children's creativity and undermine their potential to collaboratively construct innovative solutions to societal problems.
Biocomposites based on sea algae fibers and biodegradable thermoplastic matrices (1999)

Composites were prepared by mixing thermoplastic biodegradable polymers with sea algae fibers. Tensile mechanical properties were analyzed as a function of fiber concentration. The effect of processing, such as compression molding and calendering, on the mechanical properties of the materials was investigated. Composites showed higher elastic modulus and lower strength than the matrix components. Fiber damaging, characterized by a reduction of both length and diameter, was observed in the composites. Films, prepared by calendering operations, showed anisotropic properties due to fiber alignment. © 1999 John Wiley & Sons, Inc. J Appl Polym Sci 73: 583–592, 1999
A potential role for antigen selection in the clonal evolution of Burkitt's lymphoma. (1994)

Burkitt's lymphoma (BL) is a monoclonal lymphoproliferative disorder characterized by the presence of specific chromosomal translocations that involve the c-myc proto-oncogene. Two subtypes of BL exist (endemic and sporadic) that differ in the prevalence of EBV genome expression. Although EBV infection may promote cellular proliferation in endemic BL, little is known about the forces that drive clonal expansion and evolution in the majority of EBV-negative sporadic BL. This study on an EBV-negative sporadic BL cell line derived from an AIDS patient provides evidence that antigenic stimulation may play a role in the development and/or expansion of such tumors. This cell line (BRG-P) contained a series of cellular clones that elaborated both IgM and IgA. Southern blot analyses of the line and its sublines indicated that both the IgM+ and IgA+ cells had identical c-myc and Ig JH gene rearrangements, indicating that they were derived from a common precursor, some of which eventually underwent an isotype switch. Ig VH gene sequence analyses of 21 molecular clones derived from the parental BRG BL line and two of its sublines demonstrated that all the clones used the same VH3 gene. Five unique intraclonal variants were identified at four distinct nucleotide positions (125, 161, 355, 375), which undoubtedly represented somatic mutations. Four of these five mutations occurred within complementary determining regions; all resulted in amino acid replacements. Moreover, an identical G to A nucleotide substitution that resulted in an identical amino acid change occurred at two distinct points in clonal evolution that were separated by the isotype class switch. Thus, the locations and types of the VH gene mutations, together with the occurrence of an isotype switch, are highly suggestive of an ongoing role for Ag stimulation and selection in the evolution of the malignant clone.
Vertical junction Si cells for concentrating photovoltaics (2011)

ABSTRACT Vertical junction Si cell has shown a potential to operate at high concentrations, mainly the result of reduced series resistance losses due to its low‐current/high‐voltage design, but tests and analyses have so far only shown a modest efficiency of about 20%. We perform a comprehensive optimization study and show that the conversion efficiency of vertical multi‐junction (VMJ) cells can be significantly higher, close to 30% at concentrations of 1000 and higher. Reaching this efficiency requires junction dimensions that are significantly smaller than previous VMJ cells. This may require a different approach in the fabrication process, possibly by using a monolithic method rather than the wafer stacking approach. We also show that increased photoconductivity, which is usually negligible in conventional cells, produces a significant reduction in series resistance at high concentrations making it a significant contributor to the outstanding performance of the VMJ cell at high concentration.

Size effects in materials due to microstructural and dimensional constraints: a comparative review (1998)

Effects of size on predominantly mechanical properties of materials are reviewed at a first-order level. Microstructural constraints, e.g. due to second-phase particles and grain boundaries, and dimensional constraints in small-scale materials such as thin films are distinguished. Phenomena addressed are particle strengthening in plasticity, creep and magnetism, grain size strengthening and the limits to Hall–Petch behavior as well as the yielding of thin films and multilayers. Important aspects can be understood from the point-of-view of the interaction of a characteristic length (which may be as diverse as the dislocation radius of curvature at a given stress or the magnetic exchange length) with a size parameter (grain or particle size, or film thickness). It is demonstrated that such an approach can reveal interesting analogies between otherwise very different properties of materials.
A stoicheiometric conversion of CO2+ CH4 into 2 CO + 2 H2 by microwave discharge (1982)

Microwave discharge caused a mixture of CO2 and CH4 to undergo a stoicheiometric conversion into a mixture of CO and H2, while discharge of CH4 alone gave C2H2 and discharge of CH4 in Xe yielded solid carbonaceous materials.
Adamantyl-Substituted <i>N</i>-Heterocyclic Carbene Ligands in Second-Generation Grubbs-Type Metathesis Catalysts (2003)

The N-heterocyclic carbene (NHC) ligands H2IAd (H2IAd = 1,3-di(1-adamantyl)-4,5-dihydroimidazol-2-ylidene) and H2IAdMes (H2IAdMes = 1-(1-adamantyl)-3-mesityl-4,5-dihydroimidazol-2-ylidine) were prepared and treated with [RuCl2(CHPh)(PCy3)2] (1). While H2IAd failed to react with 1, H2IAdMes readily produced [RuCl2(CHPh)(H2IAdMes)(PCy3)] (7). Only a single isomer of 7 was formed, this being that with the mesityl ring situated above the benzylidene moiety, as confirmed by an X-ray structure. Complex 7 was found to be only a very poor olefin metathesis catalyst, likely a consequence of the excessive steric crowding imparted by the 1-adamantyl moiety towards the position trans to the benzylidene group.
Highly active thiol-functionalized SBA-15 supported palladium catalyst for Sonogashira and Suzuki–Miyaura cross-coupling reactions (2014)

SBA-15 supported heterogeneous Pd-catalyst was prepared and applied towards Sonogashira and Suzuki–Miyaura cross-coupling reactions of activated and inactivated aryl halides to give the corresponding coupling products in up to 98% yield.
In Situ STM and STS Study of Co and Co−Al Alloy Electrodeposition from an Ionic Liquid (2003)

The electrocrystallization of Co and Co−Al alloys has been investigated for the first time from a chloroaluminate ionic liquid, AlCl3/[BMIm]+Cl-, on Au(111) by in situ electrochemical scanning tunneling microscopy (STM) and spectroscopy (STS). In contrast to Ni deposition (Zell, C. A.; Freyland, W. Proc. Electrochem. Soc. 2002, 19, 660), the formation of a coherent Co monolayer is not observed in the underpotential range. Instead, 2D phase formation sets in at slightly cathodic potentials characterized by monatomically high Co islands with a radius of 2−3 nm and a narrow size distribution. Their growth behavior has been studied as a function of time and overpotential η in the range −0.05 ≤ η/V ≤ −0.17 versus Co/Co(II). It can be described by a classical nucleation model yielding a critical nucleus of 1−2 atoms. At potentials below −0.2 V, a fast 3D growth of Co clusters is manifest. Although Co and Au are immiscible in the bulk phase at room temperature, the STM images give clear evidence of surface alloying for 2D and 3D cluster deposits. Co-deposition of Co and Al has been studied in the potential range −0.3 ≤ η/V ≤ −0.7. It is found that the grain size of the CoxAl1-x clusters decreases with increasing Al content. Particularly remarkable is the result that the composition of CoxAl1-x can be controlled in situ with nanometer resolution on a time scale of milliseconds, the typical time for recording the tunneling spectra being ∼200 μs. This is demonstrated by the variation of the effective tunneling barrier φ as a function of η as determined from STS measurements. It quantitatively agrees with independent composition determinations by conventional electrochemical methods. This correlation has not been reported before.
<i>IRF7</i> inhibition prevents destructive innate immunity—A target for nonantibiotic therapy of bacterial infections (2016)

Boosting innate immunity represents an important therapeutic alternative to antibiotics. However, the molecular selectivity of this approach is a major concern because innate immune responses often cause collateral tissue damage. We identify the transcription factor interferon regulatory factor 7 (IRF-7), a heterodimer partner of IRF-3, as a target for non-antibiotics-based therapy of bacterial infections. We found that the efficient and self-limiting innate immune response to bacterial infection relies on a tight balance between IRF-3 and IRF-7. Deletion of Irf3 resulted in overexpression of Irf7 and led to an IRF-7-driven hyperinflammatory phenotype, which was entirely prevented if Irf7 was deleted. We then identified a network of strongly up-regulated, IRF-7-dependent genes in Irf3(-/-) mice with kidney pathology, which was absent in Irf7(-/-) mice. IRF-3 and IRF-7 from infected kidney cell nuclear extracts were shown to bind OAS1, CCL5, and IFNB1 promoter oligonucleotides. These data are consistent in children with low IRF7 expression in the blood: attenuating IRF7 promoter polymorphisms (rs3758650-T and rs10902179-G) negatively associated with recurrent pyelonephritis. Finally, we identified IRF-7 as a target for immunomodulatory therapy. Administering liposomal Irf7 siRNA to Irf3(-/-) mice suppressed mucosal IRF-7 expression, and the mice were protected against infection and renal tissue damage. These findings offer a response to the classical but unresolved question of "good versus bad inflammation" and identify IRF7 as a therapeutic target for protection against bacterial infection.
Energy Savings Forecast of Solid-State Lighting in General Illumination Applications (2016)

The DOE report, Energy Savings Forecast of Solid-State Lighting in General Illumination Applications, is a biannual report which models the adoption of LEDs in the U.S. general-lighting market, along with associated energy savings, based on the full potential DOE has determined to be technically feasible over time. This version of the report uses an updated 2016 U.S. lighting-market model that is more finely calibrated and granular than previous models, and extends the forecast period to 2035 from the 2030 limit that was used in previous editions.
Interactive graphics for volume modeling (1982)

This paper describes the GRaphic INput subsystem (GRIN) of an experimental volume modeling system called the Geometric Design Processor (GDP) developed at the IBM Thomas J. Watson Research Center. Sitting at an interactive graphic workstation, a mechanical designer generates computer volume models of complex physical objects and mechanisms built up from primitive volumes, e.g., cuboids, cylinders, swept surfaces, etc., entered at any orientation in 3-dimensional space. Objects are represented in the model as polyhedral approximations. The central issue is the provision of an efficient, natural means for a mechnical designer to enter and interact with these models.

Seismic anisotropy at Hydrate Ridge (2006)

P‐wave velocity increases in the presence of gas hydrates and decreases in the presence of free gas in the sediments, making it an excellent means to investigate gas hydrate systems. However, seismic velocity is typically derived from surface seismic data without consideration of seismic anisotropy. The presence of anisotropy in the hydrate bearing sediments adds an additional complexity in data analysis; however anisotropy can help reveal the distribution of hydrates. Here we report on the evidence of seismic anisotropy at Hydrate Ridge along the Cascadia convergent margin. We find that the south summit is anisotropic, while the basin side (east of south summit) is isotropic. Anisotropy is likely caused by the hydrate veins. We interpret the anisotropy parameters in terms of the distribution and fabric of gas hydrates.
Sequential appearance of fibronectin and collagen in experimental granulation tissue. (1980)

The sequential appearance of fibronectin and collagenous proteins was studied by immunofluorescence in experimental granulation tissue in the mouse. Granulation tissue was induced by subcutaneous implantation of viscous cellulose sponges into the neck. When sponges were invaded by granulation tissue, fibronectin appeared early together with the invading fibroblasts. Interstitial collagens, type III and type I, appeared 2 to 7 days later. When the collagen had matured into bundles, fibronectin diminished or disappeared. The results suggest that fibronectin functions as a primary matrix for organization of the collagenous connective tissue during the tissue repair process.
PCR+ In Diesel Fuels and Emissions Research (2002)

In past work for the U.S. Department of Energy (DOE) and Oak Ridge National Laboratory (ORNL), PCR+ was developed as an alternative methodology for building statistical models. PCR+ is an extension of Principal Components Regression (PCR), in which the eigenvectors resulting from Principal Components Analysis (PCA) are used as predictor variables in regression analysis. The work was motivated by the observation that most heavy-duty diesel (HDD) engine research was conducted with test fuels that had been ''concocted'' in the laboratory to vary selected fuel properties in isolation from each other. This approach departs markedly from the real world, where the reformulation of diesel fuels for almost any purpose leads to changes in a number of interrelated properties. In this work, we present new information regarding the problems encountered in the conventional approach to model-building and how the PCR+ method can be used to improve research on the relationship between fuel characteristics and engine emissions. We also discuss how PCR+ can be applied to a variety of other research problems related to diesel fuels.
Soybean galactinol synthase forms fagopyritol B1 but not galactopinitols: substrate feeding of isolated embryos and heterologous expression (2004)

Soybean ( Glycine max (L.) Merrill) seeds accumulate sucrose, raffinose, stachyose and lesser amounts of galactopinitol A, galactopinitol B and fagopyritol B1 in axis and cotyledon tissues as part of the seed maturation process. Somatic embryos appear to be deficient in D-pinitol and galactopinitols, indicating a lack of synthesis by embryo tissues in vitro . Isolated immature soybean zygotic embryos were fed myo -inositol, D-pinitol, D- chiro -inositol and sucrose, individually and in combination, to evaluate the role of substrate availability on galactosyl cyclitol accumulation during precocious maturation. Feeding myo -inositol transiently doubled galactinol accumulation with little effect on other soluble carbohydrates. Feeding D-pinitol increased free D-pinitol 8-fold, galactopinitol A 4.5-fold and galactopinitol B 4.2-fold. Stachyose concentration was 2-fold higher in cotyledons after feeding D-pinitol than after feeding D- chiro -inositol. Feeding D- chiro -inositol increased fagopyritol B1 17-fold in the axis and 7-fold in the cotyledons, but did not increase other soluble carbohydrates. Feeding D-pinitol and D- chiro -inositol together reduced uptake of D- chiro -inositol and steady-state accumulation of galactinol and galactopinitols by 50%, compared to feeding D-pinitol alone. Increasing sucrose concentration from 0 to 200 mM had no effect. Recombinant soybean galactinol synthase, heterologously expressed in Escherichia coli , catalysed the synthesis of fagopyritol B1 and galactinol, but not galactopinitols. These results were consistent with the following interpretations: D-pinitol and D- chiro -inositol were transported from maternal tissues and not synthesized in the embryo, D- chiro -inositol uptake into embryos may be reduced by D-pinitol, fagopyritol B1 was synthesized by galactinol synthase while galactopinitols were not, and fagopyritol B1 and galactopinitols accumulated in response to the supply of free D- chiro -inositol and D-pinitol to embryos.
Controlled Release Formulations of Imidacloprid: Water and Soil Release Kinetics (2004)

Controlled release formulations of insecticide imidacloprid obtained through its monolithic dispersion/incorporation in carboxy methyl cellulose, polystyrene, and polyvinyl chloride matrices released imidacloprid in water and soil beyond 42 and 49 days respectively. The release was diffusion controlled with a half release time (T1/2 of 11.7–42.0 days in soil and 9.0–36.7 days in water from different matrices. The period of opt mum (maximum) availability of imidacloprid in water and soil from controlled released formulations ranged from 24.2–42.1 and 25.1–46.9 days, respectively.
