Abstract
Granulopoietic differentiation in long‐term bone marrow cultures from children with congenital neutropenia (1988)

The capacity of granulopoietic precursor cells (CFU-GM) to differentiate in vitro was evaluated in five children with congenital neutropenia using short-term colony assays and long-term marrow cultures. In all five children, methylcellulose assays revealed normal numbers of CFU-GM, which displayed an appropriate response to various sources of GM-CSF and differentiated up to the polymorphonuclear leukocyte state (PMN). In contrast, neutrophil PMN were not observed in long-term bone marrow cultures from three patients, despite a normal production of CFU-GM, myeloblasts, and promyelocytes during the 5-6 week culture period. Thus, in these patients, the characteristic "block" in granulocytic maturation observed in vivo was reproduced in vitro in long-term cultures. Granulocytic differentiation proceeded normally in long-term cultures from the two other patients, thus indicating heterogeneity in the expression of the defect. These results might indicate abnormal interactions between stromal and hematopoietic cells in long-term marrow cultures from some patients with congenital neutropenia. Furthermore, our results showed some correlation between the granulocytic defect in vitro and the clinical outcome in vivo.

High-speed active network node - its concept and implementation for gigabit-network applications - (2004)

The spread of the IP (internet protocol) network is giving rise to various new services. The problem is that the use of the end-to-end communication model is slowing the development of the next generation of applications. The active network (AN) as stated in D.L. Thennenhause et al. (1997) is an attempt to establish a new platform that encourages the evolution of network applications. The AN processes communication data in the network by using application-dependent protocols. Existing off-the-shelf network nodes offer only fixed functionality at the user's site, and computer systems can not support wide-bandwidth processing of telecom packets such as gigabit, Ethernet. In this paper, we introduce the overall concept of our programmable node system and its implementation. Some application implementation results are also described.

Réaction du polyisobutène chloré sur l'anhydride maléique : mécanisme. Catalyse par l'anhydride dichloromaléique (1985)

Dans cet article le mécanisme de la réaction de condensation du polyisobutène chloré sur l'anhydride maléique, qui sert dans la synthèse d'additif pour lubrifiant, est étudié par une cinétique globale et par un travail sur composés modèles. Il est montré que, dans cette réaction, l'anhydride maléique joue un double rôle : de catalyseur de déshydrochloration par une réactivité de type acide de Lewis organique, de réactif comme diénophile. Grâce à ces résultats, il est proposé une catalyse par l'anhydride dichloromaléique, qui permet une amélioration sensible du procédé.

P05.20: The association of antenatal blood flow with neonatal brain damage in very low birth‐weight infants (2004)

The aim of this study was to assess the effect of pathological blood flow to perinatal outcome in preterm very low birth-weight (£1500 g) infants. Sixty-nine infants with antenatal Doppler flow measurements were included. Doppler velocity waveforms from umbilical (UA), middle cerebral artery (MCA), descending aorta (DA), ductus venosus and aortic isthmus were assessed. UA/MCA and DA/MCA ratios were calculated. Adverse outcome included neonatal death, 5-minute Apgar scores < 7, umbilical arterial pH < 7.05, intraventricular hemorrhage (IVH) from birth to term and periventricular leucomalacia (PVL). Neonatal cranial ultrasound examinations were performed sequentially from day 3 until term. Chi-square test or ANOVA were used to compare perinatal outcome of fetuses with normal or pathological blood flow. Six infants (8.7%) died after birth. The infants with pathological blood flow were more often SGA compared to those with normal blood flow (P = 0.01). Otherwise, pathological fetal blood flow did not impair neonatal outcome. Pathological fetal blood was not associated with neonatal brain damage in very low birth-weight infants.

Performance analysis of radial and axial flux fractional horsepower motors (2016)

This paper shows that axial flux motors are compact, torque dense, efficient replacements for radial flux fractional horsepower motors. A commercially available radial flux fractional horsepower motor is used as baseline for design of its axial flux counterpart. The torque density and losses of the radial and axial flux motors, with identical permanent magnet utilization factors, are compared with finite elements. An additional design is presented to demonstrate its ability to overcome the major challenge of axial flux designs without compromising performance.
Role of sialic acid in the kinetics of Streptococcus sanguis adhesion to artificial pellicle (1987)

Evaluation of the kinetics of adhesion of Streptococcus sanguis 10556 to saliva-coated hydroxylapatite revealed that sialic acid played a role in the formation of a stable cell-substratum complex. In a previous paper (M. M. Cowan, K. G. Taylor, and R. J. Doyle, J. Dent. Res. 65:1278-1283, 1986) the adhesion was found to take place in two distinct stages: a reversible equilibrium, probably governed by long-range forces, followed by a transition to higher-affinity binding. In the present study, artificial pellicle was treated with neuraminidase, and kinetic adsorption and desorption experiments with S. sanguis were conducted. The depletion of sialic acid from pellicle decreased the initial adsorption rate constant only slightly. The rate constant describing the initial desorption was unaffected. However, no transition to the second (high-affinity) association occurred. While S. sanguis desorption from control pellicles exhibited two sequential rates, with the second rate being approximately 10 times slower than the first, all desorption from sialo-deficient pellicles occurred at one rate that was equivalent to the initial rate constant for control desorption. The cells did not reach an equilibrium with the sialo-deficient pellicle, even after 6 h. Competing sialic acid did not decrease the rate or extent of adsorption, but desorption occurred to a greater extent when cells had adsorbed in the presence of sialic acid. These data suggest that sialic acid plays little role in the initial association of cell and pellicle but that it is necessary for the transition to high-affinity binding and the concomitant decreased propensity to desorb.

Antenna Pattern Synthesis in Operational Environments With Electromagnetic Compatibility-Based Constraints (2004)

A general linear least squares synthesis technique for antenna arrays is presented that takes account of mutual coupling among array elements and interactions with array's physical surroundings. The technique can be applied to optimize the radiation pattern of arbitrary arrays in their operational environment while simultaneously addressing electromagnetic compatibility based constraints. Examples employing the wire and plate-dielectric (WIPL-D) numerical code are presented to illustrate the approach. Use of this technique with experimental data has also been performed and will be reported in future paper.

Floc Formation and Changes in Serum Soluble Cloud Components of Fresh Valencia Orange Juice (2003)

ABSTRACT: The pH of pulp‐free juice (PFJ) from Valencia oranges was adjusted, ultracentrifuged to produce serum (UCS) and pellet (UCP), and stored at 4 °C for 11d. The UCS and PFJ had no pectinmethylesterase (PME) activity. Floc (UCF) in the UCS appeared at the same time as the %T increase in PFJ. Presumptively, PME peptides at 13‐, 20‐, 27‐, and 36‐kDa were in UCF and UCP. The UCS had no protein. Soluble (in UCS) and insoluble (in PFJ) proteins are involved in clarification. Steric stabilization and charge repulsion at pH 7 delays clarification. Increased charge, loss of steric stabilization, and loss of charge repulsion of juices readjusted from pH 7 to natural pH led to accelerated clarification.
Differentiation of Catalyst Types in the Formaldehyde-Cotton Cellulose Reaction1 (1984)

Differences in effectiveness between a Bronsted acid catalyst (hydroxymethane sulfonic acid) and two commonly employed Lewis acid catalysts (Zn(NO 3 ) 2 and MgCl 2 ) on the pad-cure reaction of formaldehyde with cotton cellulose were determined in statistical experimental designs. The effects of each catalyst were followed by measured textile properties. Two methods for comparison of properties, one based on equal durable press appearance and a second based on equal conditioned wrinkle recovery angles, indicated that cotton reacted with formaldehyde in the presence of the Bronsted acid catalyst generally had superior resilience properties. Cotton reacted in the presence of the Lewis acid catalysts had better strength retentions at equivalent resilience by either method of comparison, and better abrasion properties by the method based on durable press appearance. Cotton reacted with formaldehyde and Lewis acid catalysts to a durable press appearance rating of 4.0-4.3 had better strength, abrasion, and wrinkle recovery angles than cottons reacted with formaldehyde in the presence of the Bronsted acid.
INEEL Biotechnology for Oilfield Application--Microbial Enhanced Oil Recovery FY-03 Report (2003)

The Idaho National Engineering and Environmental Laboratory (INEEL) Biotechnology for Oilfield Operations program supports development, engineering, and application of biotechnology for exploration and production. This continuing INEEL program also supports mitigation of detrimental field conditions. The program is consistent with the United States Department of Energy mission to ¡§promote activities and policies through its oil technology and natural gas supply programs to enhance the efficiency and environmental quality of domestic oil and natural gas exploration, recovery, processing, transport, and storage.¡¨ In addition, the program directly supports the focus areas of Reservoir Life Extension; Advanced Drilling, Completion and Stimulation Systems; Effective Environmental Protection; and Cross Cutting Areas. The program is enhanced by collaborative relationships with industry and academia. For fiscal year 2003, the program focused on production and characterization of biological surfactants from agricultural residuals and the production and application of reactive microbial polymers. This report specifically details: 1. Use of a chemostat reactor operated in batch mode for producing surfactin, with concomitant use of an antifoam to prevent surfactant loss. The program achieved production and recovery of 0.6 g/L of surfactin per 12 hr. 2. Characterization of surfactin produced from agricultural residuals with respect to its ability to mediate changes in surface tension. Conditions evaluated were salt (as NaCl) from 0 to 10% (w/v), pH from 3 to 10, temperature from 21 to 70¢XC, and combinations of these conditions. When evaluated singularly, pH below 6 and salt concentrations above 30 g/L were found to have an adverse impact on surfactin. Temperatures of 70¢XC for 95 days had no effect. When the effect of temperature was added to the pH experiment, there were no significant changes, and, again, surface tension, at any temperature, increased at pH below 6. When temperature (70¢XC) was added to the experiments with salt, the impacts of salt up to 30 g/L were negligible. When all three parameters were combined in one experiment, no increase in surface tension was observed at 80 g/L NaCl, pH 10, and 70¢XƒnC. The upper temperature limit of the surfactin was not determined in these experiments. 3. Impact of alkaline soluble, pH reactive biopolymers to alter permeability in Berea sandstone cores. The contributing effect of salt (as NaCl to 2%, w/v), temperatures to 60¢XC, and crude oil were evaluated. Residual resistance factors were increased 800 fold, compared to cores without biopolymer. This could lead to alternate technology for permeability modification, thus extending the life of a reservoir and preventing premature abandonment.
Age-Induced Changes in the Microstructure and Selected Properties of Extruded Starch Films Plasticized with Glycerol and Stearic Acid (2009)

Aging of normal corn starch films processed by extrusion and stored at 20−22 °C and 50−56% RH was investigated over a period of 120 d. The changes in the structural, thermal, tensile, and water vapor permeability (WVP) properties of the films during aging were studied. The thermoplastic starch (TPS) just after extrusion processing (≈4 h) was nearly amorphous in character. However, aging above the Tg produced both B- and V-type crystalline structures in the TPS within 3 d of drying. The relative crystalline content of the TPS increased from 2.6 to 17.7%, depending on the glycerol content. Post-processing, the tensile strengths of the films increased by 39.3−134.1% while the tensile strains decreased by 48−81.1%. The rates of change in tensile strength and strain were faster during the first 30 d but stabilized thereafter. The biphasic transitions in the DSC thermograms suggested phase separation in the TPS. The Tg of glycerol-rich domains decreased while those of the starch-rich regions increased during storage. The band-narrowing and changes in peak styles and intensities in the 1400−800 cm−1 region of the Fourier transform infrared spectra suggested increases in the crystalline content of the TPS during aging. The WVP values tended to decrease with time as the crystallinity of starch increased and the free volume in the film network decreased.
Antimicrobial Macroporous Gel-Glasses: Dissolution and Cytotoxicity (2003)

The incidence of biomaterial-centred infections underlies the need to improve the properties of existing biomaterials. Combining the bioactive properties of calcia-silicate gel-glasses with that of the silver would prevent infections without the use of antibiotic drugs. Inclusion of silver into bioactive gel-glass foam scaffolds is explored using in vitro characterization techniques. The amount of silver released from Ag-doped S70C30 foams is well above the minimum bactericidal concentration (0.1 ppm) but below the cytotoxic concentration (1.6 ppm) for human cells. Primary human osteoblasts proliferate on the silver-doped gel-glasses.
Carbon−Hydrogen Bond Activation and Cyclodehydrogenation Reactions of Cyclic C<sub>8</sub> Hydrocarbons on Pt(111) (1998)

The mechanisms of the thermolytic decomposition of a series of unsaturated cyclic C8 hydrocarbons adsorbed on a platinum(111) single crystal surface are described. This study both confirms and extends the results reported by Frei and Campbell which corrected errors in an earlier report from our laboratory on the mechanisms of thermal decomposition seen in this adsorbate system. We find that the dehydrocyclization of cyclooctene, cyclooctadiene (1,3 and 1,5 isomers), and cyclooctatetraene on Pt(111) proceeds through a related set of intermediates and ultimately yields a novel surface-bound bicyclic ring system. As noted by Frei et al., our earlier finding that benzene is produced in high yield is incorrect. The spectroscopic evidence reported here demonstrates that all four of the cyclic C8 hydrocarbons form a bicyclo[3.3.0]octenyl (or, as more commonly named, a pentalenyl) intermediate of stoichiometry C8H6. This bicyclic ring system forms via a dehydrocyclization of cyclooctatetraene, which itself is formed in varying yields from each of the less-unsaturated c-C8 adsorbates. The formation of the pentalenyl species proceeds at low temperatures (<375 K). Data from reflection−absorption infrared (RAIRS) and temperature-programmed reaction spectroscopies show that the pentalenyl intermediate is remarkably stable, persisting on the surface up to at least 450 K. At temperatures above 450 K, this intermediate fragments, liberating hydrogen, and leaving a carbonaceous overlayer. The formation of cyclooctatetraene, and thus the pentalenyl intermediate, proceeds with the highest efficiency for the two dienes and lowest for cyclooctane and cis-cyclooctene. RAIRS data further serve to identify several intermediates formed along the reaction pathway leading to the platinum-bound C8H6 species.
DEFICIENCY OF THE FIFTH COMPONENT OF COMPLEMENT IN MICE WITH AN INHERITED COMPLEMENT DEFECT (1967)

The inherited complement deficiency of certain inbred strains of mice was shown to be due to an isolated lack of the fifth component of complement. The protein MuB1 (or hc'), which is present in normal mouse serum but absent from the serum of complement-deficient mice, was shown to be immunochemically related to the fifth component of human complement (C'5). C'5 hemolytic activity was specifically inhibited in human serum by mouse anti-MuB1 and in normal mouse serum by mouse antiserum to human C'5. Highly purified human C'5 reconstituted the hemolytic activity of complement-deficient mouse serum. It was, therefore, concluded that he', or MuB1, constitutes the murine analogue of the fifth component of human complement. The MuB1 concentration in normal mouse serum was found to be subject to a sex-related variation. By quantitative precipitin analysis it was demonstrated that serum from male mice contains twice as much MuB1 as that of female mice. This difference in C'5 concentration was also detected by hemolytic assay. In addition, C'6 and C'7 were also found to be subject to sex-related variations.
