A Novel and Convenient Process for the Selective Oxidation of Naphthalenes with Hydrogen Peroxide (2007)

Abstract A practical ruthenium phase‐transfer catalyst (Ru‐PTC) system for the oxidation of naphthalene derivatives has been developed. Substituted 1,4‐quinones are obtained in good selectivity and yield in water without the addition of any organic solvent and acid. By applying the optimized conditions the feed additive menadione (vitamin K 3 ) is obtained from 2‐methylnaphthalene with 64 % yield and 73 % selectivity.

Circannual variation in human erythrocyte adenosine aminohydrolase. (1978)

In serially independent samples of blood from apparently healthy subjects controlled as to clock-hour of blood withdrawal but not as to any circannual changes in circadian state, human erythrocyte adenosine aminohydrolase undergoes a statistically significant circannual rhythm, which may or may not be aliased. This rhythm is also demonstrated in patients with a variety of neoplastic diseases and it occurs around a statistically significantly lower mesor in patients with a variety of malignant tumors investigated.
Variations in the Social Impact of Oral Conditions Among Older Adults in South Australia, Ontario, and North Carolina (1996)

Previous studies among older adults have demonstrated that oral disease frequently leads to dysfunction, discomfort, and disability. This study aimed to assess variations in the social impact of oral conditions among six strata of people aged 65 years and older: residents of metropolitan Adelaide and rural Mt Gambier, South Australia; residents of metropolitan Toronto-North York and non-metropolitan Simcoe-Sudbury counties, Ontario, Canada; and blacks and whites in the Piedmont region of North Carolina (NC), United States. Subjects were participants in three oral epidemiological studies of random samples of the elderly populations in the six strata. Some 1,642 participants completed a 49-item Oral Health Impact Profile (OHIP) questionnaire which asked about impacts caused by problems with the teeth, mouth, or dentures during the previous 12 months. The percentage of dentate people reporting impacts fairly often or very often was greatest among NC blacks for 41 of the OHIP items. Two summary variables of social impact were used as dependent variables in bivariate and multivariate least-squares regression analyses. Among dentate people, mean levels of social impact were greatest for NC blacks and lowest for NC whites, while people from South Australia and Ontario had intermediate levels of social impact (P < 0.01). Missing teeth, retained root fragments, root-surface decay, periodontal pockets, and problem-motivated dental visits were associated with higher levels of social impact (P < 0.05), although there persisted a two-fold difference in social impact across the six strata after adjustment for those factors Among edentulous people, there was no statistically significant variation in social impact among strata. The findings suggest that there are social and cultural factors influencing oral health and its social impact, and that those factors differ most between dentate blacks and whites in NC.
Three-dimensional vortex pinning by nano-precipitates in a Sm-doped YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7−<i>x</i></sub>coated conductor (2007)

We report on the thickness and angular dependence of the critical current density Jc(H,θ), the irreversibility field Hirr, and the bulk pinning force Fp(H) of a metal-organic chemical vapour deposition (MOCVD) grown YBa2Cu3O7−x (YBCO) coated conductor, which contains ∼17 vol% of ∼10 nm sized (Y,Sm)2O3 precipitates with an average spacing of ∼10–15 nm. Some surface porosity and amorphous second-phase particles on the scale of ∼0.5–1 µm appear to reduce the current-carrying cross-section, which controls the magnitude of Jc but not the vortex pinning. We observed an enhanced Hirr∼9 T at 77 K along the c-axis which, like the shape of Jc(H) and Fp(H), was independent of thickness as the sample was milled down to ∼0.16 µm. Angular-dependent measurements of Jc showed the usual excess vortex pinning along the c-axis and along the ab-plane, but with a background that could only be fitted with an unusually small anisotropy parameter of 3, which, like the high Hirr and the thickness-independent shape of Fp(H), we ascribe to strong vortex pinning centre interactions. Together, these measurements show very different behaviour from most pulsed-laser-deposited films, which exhibit strong thickness-dependent properties. We ascribe the present different results to the dense array of small, insulating precipitates, which act as strong pinning centres and produce strong three-dimensional (3D) vortex pinning, because their separation of 10–15 nm is always much smaller than the film thickness.

Design and Photochemical Characterization of a Biomimetic Light-Driven Z<i>/</i>E Switcher (2004)

Protonated Schiff bases (PSBs) of polyenals constitute a class of light-driven switchers selected by biological evolution that provide model compounds for the development of artificial light-driven molecular devices or motors. In the present paper, our primary target is to show, through combined computational and experimental studies, that it is possible to approach the design of artificial PSBs suitable for such applications. Below, we use the methods of computational photochemistry to design and characterize the prototype biomimetic molecular switchers 4-cyclopenten-2'-enylidene-3,4-dihydro-2H-pyrrolinium and its 5,5'-dimethyl derivative both containing the penta-2,4-dieniminium chromophore. To find support for the predicted behavior, we also report the photochemical reaction path of the synthetically accessible compound 4-benzylidene-3,4-dihydro-2H-pyrrolinium. We show that the preparation and photochemical characterization of this compound (together with three different N-methyl derivatives) provide both support for the predicted photoisomerization mechanism and information on its sensitivity to the molecular environment.
[A colorimetric method for the evaluation of phagocytosis by mouse peritoneal macrophages (author's transl)]. (1981)

In this study, a technique for the evaluation of circulating leukocyte phagocytosis has been adapted to mouse peritoneal macrophages. This quantitative determination was performed by the spectrophotometric measurement of the reduced nitroblue tetrazolium (NBT) fixed on bacteria or latex spherules. Capacity of phagocytosis was thus correlated with the intensity of the NBT intracellular reduction by macrophages. This method is technically simple and requires no expensive materials. The phagocytosis of latex did not significantly differ, neither in the presence of autologous or heterologous serum (X +/- G = 0.100 +/- 0.014/2.5 X 10(6) cells) nor in the absence of serum (X +/- G = 0.088 +/- 0.007/2.5 X 10(6) cells). The use of macrophages suspended in the culture medium highly decreased the phagocytic activity (X +/- G = 0.021 +/- 0.002/2.5 X 10(6) cells) and confirmed thus the role played by the support in endocytosis. A specific antiserum weakly enhanced the phagocytic process for Escherichia coli. The mean values with and without serum were 0.065 +/- 0.005/2.5 X 10(6) cells and 0.050 +/- 0.005, respectively. Heating of the serum (56 degrees C, 30 min) and inhibition of both complement activation pathways by EDTA showed that complement plays the major role in this weak enhancement of bacterial phagocytosis by peritoneal mouse macrophages. Bacterial phagocytic stimulation of macrophages was not induced by addition of CA+++ or Mg++ into the culture medium.
PROMOTING EFFECT OF Mo ON Pd / g-Al2O3 SUPPORTED CATALYSTS IN THE OXIDATIVE DEHYDROGENATION OF PROPANE (2011)

Bimetallic catalysts of Pd-Mo supported on g-Al2O3 were prepared to study the interaction of Pd-Mo in terms of their structural properties and their catalytic activity for the reaction of oxidative dehydrogenation of propane (ODHP). The catalysts contain distributions of Pd- Mo loads between 0 and 5 wt %, and were characterized by total surface area (TSA), total pore volume (TPV), active surface area (ASA), XRD, and TEM-EDS. The results indicate that the addition of Mo to catalysts of Pd/g-Al2O3 modifies its catalytic activity for the ODHP reaction. The influence of the load relationship Pd-Mo in the catalytic activity was determined. Monometallic catalysts were prepared for purposes of comparison.
Three-dimensional fluorescence-enhanced optical tomography using a hand-held probe based imaging system (2008)

Hand-held based optical imaging systems are a recent development towards diagnostic imaging of breast cancer. To date, all the hand-held based optical imagers are used to perform only surface mapping and target localization, but are not capable of demonstrating tomographic imaging. Herein, a novel hand-held probe based optical imager is developed towards three-dimensional (3-D) optical tomography studies. The unique features of this optical imager, which primarily consists of a hand-held probe and an intensified charge coupled device detector, are its ability to; (i) image large tissue areas (5 x 10 sq. cm) in a single scan, (ii) perform simultaneous multiple point illumination and collection, thus reducing the overall imaging time; and (iii) adapt to varying tissue curvatures, from a flexible probe head design. Experimental studies are performed in the frequency domain on large slab phantoms (approximately 650 ml) using fluorescence target(s) under perfect uptake (1:0) contrast ratios, and varying target depths (1-2 cm) and X-Y locations. The effect of implementing simultaneous over sequential multiple point illumination towards 3-D tomography is experimentally demonstrated. The feasibility of 3-D optical tomography studies has been demonstrated for the first time using a hand-held based optical imager. Preliminary fluorescence-enhanced optical tomography studies are able to reconstruct 0.45 ml target(s) located at different target depths (1-2 cm). However, the depth recovery was limited as the actual target depth increased, since only reflectance measurements were acquired. Extensive tomography studies are currently carried out to determine the resolution and performance limits of the imager on flat and curved phantoms.
Effects of Ionizing Radiation on Food Contact Materials (2004)

FDA's Office of Food Additive Safety is responsible for the evaluation of food additive petitions and pre-market notifications requesting approval of new food contact materials for irradiation. Our lab supports that review process by conducting research to identify and quantify the products formed in food contact polymers after exposure to ionizingr adiation and then determining whether any of these compounds migrate into food. A major objective of this research is to assist in the development of guidance to manufacturers seeking FDA approval to irradiate their products. Different polyesters, polyamides, a high-density polyethylene, and an ethylene vinyl alcohol copolymer were evaluated before and after exposure to different levels of gamma and electron-beam radiation. Volatile chemicals were isolated from the test materials using static headspace sampling and analyzed by gas chromatography with mass selective detection. Semi-volatile and non-volatile chemicals were extracted from the test materials using a variety of solvents including n-heptane, a fatty food simulating solvent, and the extracts were analyzed using high performance liquid chromatography with mass selective detection. The extracts containing semi-volatiles were also analyzed by gas chromatography with mass selective detection. Most of the chemicals found are thought to be products of the polymerization process or conversion of the polymer(s) into a finished package, and breakdown products of polymer additives. Although exposure to ionizing radiation increases the concentration of some of these chemicals and decreases the concentration of other chemicals, few of the chemicals determined are thought to be chemicals specifically formed by ionizing radiation. Results of these analyses and data on the migration of some of the chemicals are presented.
Species-specific inhibition of fertilization by a peptide derived from the sperm protein bindin. (1993)

The sperm protein bindin is responsible for the species-specific adhesion of the sperm to the egg. The regions of the bindin molecule responsible for forming the contact between the sperm and the egg were investigated by measuring the ability of peptides representing various regions of the bindin sequence to inhibit fertilization. Twenty-four peptides were studied: 7 based on the Strongylocentrotus purpuratus bindin sequence, 11 based on the S. franciscanus bindin sequence, and 6 control peptides. Values for the concentration of peptide required to inhibit 50% of the productive sperm contacts (IC50) were extracted from experimental measurements of the extent of fertilization in the presence of various concentrations. of these peptides. The IC50 value averaged 220 microM for the control peptides. Active peptides representing certain specific subregions of the bindin sequence displayed IC50 values < 10% of the average value for control peptides, and the IC50 for the most potent of the peptides tested was only approximately 1% of the control peptide value (IC50 = 2.2 microM). Furthermore, we found that a peptide representing a particular region of the S. franciscanus bindin sequence that differs from the S. purpuratus bindin sequence inhibits fertilization species specifically. For the reaction of S. purpuratus sperm and eggs, the IC50 of this peptide was approximately 120 microM, whereas for the reaction of S. franciscanus sperm and eggs it was only 8.6 microM. These results demonstrate that a few specific regions of the bindin molecule are involved in the sperm-egg contact and that certain of these regions mediate the species specificity of the interaction in a sequence-specific manner.
<title>Low-power protein crystallography using polycapillary optics</title> (2000)

This paper describes the design and performance of a low power protein crystallography system using polycapillary optics. The characterization of the source and polycapillary optics are presented. Three optic types: collimating, slightly focusing and strongly focusing optics have been used in low power source-optic combination systems. The source-collimating optic and source- slightly focusing optic systems were used to collect data sets for chicken egg-white Lysozyme with conventional sample oscillation during data collection. The data sets show high quality by analysis with a conventional software package, DENZO. Still diffraction patterns without oscillation have also been obtained by a low power source-strongly focusing optic combination. These patterns have been analyzed by developing software for processing diffraction patterns obtained with strongly convergent X-ray beams. The directions of future work and system improvements are also discussed.
A Study on Mechanical Damage of Tumor Microvasculature Induced by Alternate Cooling and Heating (2009)

Tumor microvascular damage caused by the alternate cooling and heating treatment was found much more severe than that of cooling or heating alone from our previous experimental studies. The induced stresses on the vessel wall are expected to play an important role in vascular damage. Both thermal and mechanical stresses are involved due to the rapid changes in temperature and blood reperfusion during the treatment. To investigate the stress effect, theoretical modeling and numerical simulations have been performed in the present study. Thermal stresses on the tumor microvessel wall during the freezing process are analyzed using the elastic models through the coupled field method. To simulate mechanical stresses induced by blood reperfusion, the fluid and structural mechanics are coupled on the interface between the blood flow domain and the vessel wall. Numerical results show that the thermal stress on the vessel wall is negative in the tumor center, indicating the compression effect during the freezing process. The magnitude of the radial stress reaches 2.5×107 dyn/cm2. During the postheating process, the nonuniform stress distribution exists in the tortuous periphery vessel wall owing to the irregular structures, and higher stresses normally appear at the vessel bifurcations. Synergy of the thermal and mechanical stresses on the vessel wall play critical roles in damaging of the heterogeneous tumor vasculature during the alternate cooling and heating treatment. Results obtained in the present study are expected to help better understand the vascular injury process, and to develop a more effective thermal treatment protocol for tumor therapy.

Band flips and bound-state transitions in leaky-mode photonic lattices (2019)

We present analytical and numerical results on the formation and properties of the leaky stop band in one-dimensional photonic lattices. At the second stop band, one band edge mode suffers radiation loss generating guided-mode resonance whereas the other band edge mode becomes a non-leaky bound-state in the continuum. We show that the frequency location of the leaky band edge, and correspondingly the bound-state edge, is determined by superposition of Bragg processes generated by the first two Fourier harmonics of the spatial dielectric constant modulation. At the closed-band state, we discover an analytic condition for the exceptional point where frequency is fully degenerate.
Crystal Engineering with Mercuric Chloride (2002)

Two new network solids containing mercury ions are reported. The structure of HgCl4·H2tpt·H2O (tpt = 1,3,5-tri(4-pyridyl)-2,4,6-triazine) contains H2tpt2+ cations connected into 1D zigzag chains via hydrogen bonding between protonated and unprotonated pyridyl groups of adjacent cations. The third pyridyl group of each H2tpt2+ cation is also protonated and hydrogen-bonds to tetrahedral HgCl42- anions that lie as appendages to the main hydrogen-bonded chain. (HgCl2)2(hmt) (hmt = hexamethylenetetramine) contains HgCl2 and hmt molecules. The mercury is pseudo-octahedral, coordinating to two trans chloride ligands (Hg−Cl = 2.351(1) Å) and making four much longer equatorial interactions with hmt molecules (Hg−N = 2.735(4) Å) and adjoining HgCl2 molecules (Hg−Cl = 3.105(1) Å). The long Hg−N interactions link the two species into 2D (4,4) sheets, while long Hg−Cl interactions connect these sheets into an overall 3D network through chains of rhombohedral Hg−Cl···Hg−Cl··· motifs.

Device Localization in Ubiquitous Computing Environments (2008)

In this chapter, we will study the localization problem in ubiquitous computing environments. In general, localization refers to the problem of obtaining (semi-) accurate physical location of the devices in a dynamic environment in which only a small subset of the devices know their exact location. Using localization techniques, other devices can indirectly derive their own location by means of some measurement data such as distance and angle to their neighbors. Localization is now regarded as an enabling technology for ubiquitous computing environments because it can substantially increase the performance of other fundamental tasks such as routing, energy conservation, and network security. Localization is also a difficult problem because it is computationally intractable. Furthermore, it has to be implemented in a highly dynamic and distributed environment in which measurement data is often subject to noise. In this chapter, we will give an overview of localization in terms of its common applications, its hardware capacities, its algorithms, and its computational complexity.
Variable-aperture calorimeter for an unstable resonator (1976)

A new technique for measuring the output power from a cw edge-coupled unstable resonator has been developed and applied to a cw DF laser. An internal-cavity calorimeter was used that permits measurement of output power with a variable rectangular mode geometry while containing the radiation inside the resonator. The variable aperture calorimeter absorbing scraper (VACAS) device consists of an absorbing copper plate calorimeter assembly, which replaces the 45 degrees output coupling mirror of a conventional edge-coupled unstable cavity. A rectangular hole in the plate of variable width w and height h defines a rectangular mode of variable width Mw and height Mh within the geometric optics approximation, where M is the magnification. Two important applications of VACAS are (1) the determination of the optimum mode geometry for a cw diffusion-type chemical laser where there is significant variation in gain across the unstable resonator mode and (2) the determination of the power tradeoff between mode width and the number of folds in a folded unstable resonator configuration.
