Integration development for supercapacitor controlled distributed generation system (2015)

With the construction of large-scale distributed power stations, the distributed generation power imbalance becomes a serious concern as many distributed generation systems and large power grids cannot be consistent with users' load. Wind power, which is used worldwide, is regarded as the typical example of the distributed generation power. In the wind power plants, though reactive power can be easily compensated locally by adding static var devices, the compensation of active power can be difficult. In order to solve the problem, this paper conducts research on the supercapacitor (SC) energy storage system controlled wind power integration, striving to find ways to make the entire output smooth and stable. This method utilizes the characteristics of SC to compensate the intermittent wind power. Case studies on a test system are presented using wind data to substantiate the problem.
Biomechanical Evaluation of Lumbar Decompression Adjacent to Instrumented Segments (2016)

Multilevel lumbar stenosis, in which 1 level requires stabilization due to spondylolisthesis, is routinely treated with multilevel open laminectomy and fusion. We hypothesized that a minimally invasive (MI) decompression is biomechanically superior to open laminectomy and may allow decompression of the level adjacent the spondylolisthesis without additional fusion.To study the mechanical effect of various decompression procedures adjacent to instrumented segments in cadaver lumbar spines.Conditions tested were (1) L4-L5 instrumentation, (2) L3-L4 MI decompression, (3) addition of partial facetectomy at L3-L4, and (4) addition of laminectomy at L3-L4. Flexibility tests were performed for range of motion (ROM) analysis by applying nonconstraining, pure moment loading during flexion-extension, lateral bending, and axial rotation. Compression flexion tests were performed for motion distribution analysis.After instrumentation, MI decompression increased flexion-extension ROM at L3-L4 by 13% (P = .03) and axial rotation by 23% (P = .003). Partial facetectomy further increased axial rotation by 15% (P = .03). After laminectomy, flexion-extension ROM further increased by 12% (P = .05), a 38% increase from baseline, and axial rotation by 17% (P = .02), a 58% increase from baseline. MI decompression yielded no significant increase in segmental contribution of motion at L3-L4, in contrast to partial facetectomy and laminectomy (<.05).MI tubular decompression is biomechanically superior to open laminectomy adjacent to instrumented segments. These results lend support to the concept that in patients in whom a multilevel MI decompression is performed, the fusion might be limited to the segments with actual instability.MI, minimally invasive.
The use of EndoAnchors in endovascular repair of abdominal aortic aneurysms with challenging proximal neck: Single-centre experience (2019)

EndoAnchors can be safely used in the prevention and treatment of type Ia endoleaks in patients with challenging aortic necks, with good results in terms of sac exclusion and diameter reduction in the mid-term follow-up.
Nitric oxide release from the S-nitrosothiol zinc phthalocyanine complex by flash photolysis (2003)

The photogeneration of nitric oxide (NO) using laser flash photolysis was investigated for S-nitroso-glutathione (GSNO) and S-nitroso-N-acetylcysteine (NacySNO) at pH 6.4 (PBS/HCl) and 7.4 (PBS). Irradiation of S-nitrosothiol with light (lambda = 355 nm followed by absorption spectroscopy) resulted in the homolytic decomposition of NacySNO and GSNO to generate radicals (GS and NacyS ) and NO. The release of NO from donor compounds measured with an ISO-Nometer apparatus was larger at pH 7.4 than pH 6.4. NacySNO was also incorporated into dipalmitoyl-phosphatidylcholine liposomes in the presence and absence of zinc phthalocyanine (ZnPC), a well-known photosensitizer useful for photodynamic therapy. Liposomes are usually used as carriers for hydrophobic compounds such as ZnPC. Inclusion of ZnPC resulted in a decrease in NO liberation in liposomal medium. However, there was a synergistic action of both photosensitizers and S-nitrosothiols resulting in the formation of other reactive species such as peroxynitrite, which is a potent oxidizing agent. These data show that NO release depends on pH and the medium, as well as on the laser energy applied to the system. Changes in the absorption spectrum were monitored as a function of light exposure.
Factors to Consider When Designing Formulations with Multiple Functionality (2002)

From two-in-one shampoos and moisturizing facial cleansers to more exotic products such as exfoliating lipsticks and UV-protective hair sprays, multifunctional formulations have become extremely common in the marketplace. Such multifunctionality satisﬁes the consumer’s need for convenience and the marketer’s need for an exploitable product advantage. It also provides the chemist with formidable technical challenges. Overcoming these challenges will, however, require increasingly sophisticated solutions, given the intense focus that these products have received during past years.

Polychromatic AO: wavefront sensing and observing at different wavelengths (2008)

When performing adaptive optics (AO) correction for the effect of atmospheric fluctuations, different effects, related to measuring the wavefront at one wavelength and observing at another one, may show up. Some of these effects are related to the dispersive properties of the atmosphere. Others are related to diffraction, both regarding light propagation through the turbulent atmosphere to the entrance pupil of the telescope and regarding the inevitable Fraunhofer diffraction taking place for light propagating from the exit pupil to the image plane of the telescope. In this paper some of these effects are revised and discussed, in particular the way in which uncorrected wavefront errors in the point spread function (PSF) will scale with color, and the way in which dispersion affects the Strehl ratio and the background level of the AO corrected PSF. Also discussed is the trade-off between AO spectral bandwidth and Poisson noise.

Lipopolysaccharide core region ofHafnia alvei: Serological characterization (1995)

Covalent glycoconjugates containing, as a ligand lipopolysaccharide core, oligosaccharides of Hafnia alvei standard strain ATCC 13337 and R mutant 1 M were used to produce anti-H. alvei core antibodies. The sera obtained were tested in rocket immunoelectrophoresis, immunoblotting and ELISA using H. alvei lipopolysaccharides of various strains. The experiments were carried out to study the antigenic relationships between lipopolysaccharide core regions in the H. alvei genus.
Preparation and evaluation of 1,3-alternate 25,27-dibenzyloxy-26,28-bis-[3-propyloxy]-calix[4]arene-bonded silica stationary phase for high performance liquid chromatography (2006)

A new 1,3-alternate 25,27-dibenzyloxy-26,28-bis-[3-propyloxy]-calix[4]arene-bonded silica gel stationary phase (1,3-Alt CalixBz) has been prepared and used for separation of aromatic positional isomers by HPLC. The effect of organic modifier content and pH of the mobile phase on retention and selectivity were studied. The retention mechanism was also discussed. The results indicated that the stationary phase behaves like phases used in reversed-phase chromatography. However other retention mechanisms seem to be involved in separation process.
Inhibitory Effects of Antioxidant Reagent in Reactive Oxygen Species Generation and Penetration of Appressoria of Alternaria alternata Japanese Pear Pathotype (2010)

In the Japanese pear pathotype of Alternaria alternata, H2O2 is generated solely from penetration pegs and not from other portions of subcuticular hyphae within the pectin layers of host leaves. A close association between H2O2 generation and fungal aggressiveness is expected because the pegs are important for fungal penetration into the host epidermis. To determine the potential role of reactive oxygen species in microbial pathogenicity, we studied the inhibitory effects of the antioxidant reagent ascorbic acid and the NADPH oxidase inhibitor diphenylene iodonium on infection of the pathogen. In our study, we showed H2O2 generation to be inhibited by inoculation with the mixture of ascorbic acid or diphenylene iodonium and spores at the pegs in the spore-inoculated host leaves. The decrease of generation in the pegs resulted in penetration failure, indicating that H2O2 generation probably contributed to strengthening of the penetration and probably was recruited by NADPH oxidase.

Design and fabrication of asymmetric strained layer mirrors for optoelectronic applications (1993)

The design of thin-film mirrors is optimized for strained layer materials systems. It is shown that the use of asymmetric structures produces only minor loss in reflectivity per mirror period, while greatly extending the number of periods that can be grown in a defect-free mode. As applied to the GexSi1−x/Si strained layer system, the net result is an enhancement of reflectivity, with 1.3 μm mirrors achieving peak values near 75%. The approach is applicable to other materials systems and should yield even higher reflectivities in situations where wider ranges in index of refraction are available.
Shower heat exchanger: reuse of energy from heated drinking water for CO&lt;sub&gt;2&lt;/sub&gt; reduction (2016)

Abstract. The heating of drinking water in households contributes significantly to the emission of greenhouse gases. As a water utility aiming to operate at a climate neutral level by 2020, Waternet needs to reduce its CO2 emission by 53 kton yr−1. To contribute to this ambition, a pilot project was carried out in Uilenstede, Amstelveen, the Netherlands, to recover the shower heat energy with a shower heat exchanger from Dutch Solar Systems. An experimental setup was built in the Waternet laboratory to evaluate the claimed efficiencies. The energy recovery efficiency observed in the lab was 61–64 % under winter conditions and 57–62 % under summer conditions, while the energy recovery efficiency observed in Uilenstede was 57 % in December 2014. Based on the observations, 4 % of the total energy consumption of households in Amsterdam (electricity and gas) can be recovered with a shower heat exchanger installed in all households in Amsterdam, which also means a 54 kton year−1 CO2 emission reduction can be achieved.
ChemInform Abstract: Three‐Component Coupling Sequence for the Regiospecific Synthesis of Substituted Pyridines. (2012)

Abstract The de novo synthesis proceeds through the nucleophilic addition of a dithiane anion to an α,β‐unsaturated aldehyde or ketone, followed by the Ti‐mediated carbometalation of the lithium alkoxides derived from the resulting alcohols (III) with Tms‐imines (generated in situ by the low‐temperature reaction of LiN(Tms) 2 with an aldehyde), and the Hg(II)‐ or Ag(I)‐mediated ring closure.
Monte Carlo estimates of thermal averages and analytic continuation (2012)

The Monte Carlo (MC) estimates of thermal averages are usually functions of system control parameters $λ$, such as temperature, volume, interaction couplings, etc. Given the MC average at a set of prescribed control parameters $λ_{0}$, the problem of analytic continuation of the MC data to $λ$-values in the neighborhood of $λ_{0}$ is considered in both classic and quantum domains. The key result is the theorem that links the differential properties of thermal averages to the higher-order cumulants. The theorem and analytic continuation formulas expressed via higher-order cumulants are numerically tested on the classical Lennard-Jones cluster system of N=13, 55, and 147 neon particles.
Composition dependent transport properties of strain relaxed InxGa1−xAs(x&lt;0.45) epilayers (1992)

The concentration and mobility of the two-dimensional electron gas present at the interface between strain-relaxed, lattice matched, InyAl1−yAs/InxGa1−xAs(x &amp;lt; 0.45), modulation doped heterojunctions grown by means of compositionally step-graded buffer layers on GaAs substrates, were measured at room temperature and at 77 K. The composition dependence of the electron density is attributed to the dependence of the band-gap energy of InxGa1−xAs and that of InyAl1−yAs on x, with a conduction band offset, ΔEc∼0.67ΔEg. The room temperature electron mobility increases from 9×103 cm2/V s for x=0.07 to 1.05×104 cm2/V s for x=0.45. Such strain-relaxed heterostructures have higher electron mobilities than similar pseudomorphic structures with the same sheet electron concentration.
Transfer factor: forgotten, but not gone (MUC2P.934) (2015)

Abstract It has been over 70 years since the discovery of cellular immunity. Further investigation revealed that the even if immune cells are lysed and the molecular size limited to 8kDa, such injections retain some of the immunity-transferring properties. The term “transfer factor” (TF) was coined to denote the undiscovered substance responsibly for this phenomenon. Yet despite early interest, TF was all but abandoned in the 1990’s; in part due to unsubstantiated and fraudulent claims as well as the discovery of HIV, which suspended consideration of deriving therapy from blood. However, while TF was shelved as poorly elucidated, no clear explanation was provided for the observation of a small molecule harboring antigen-specific properties and therapeutic potential. Reopening this chapter, we discovered transfer factor is produced by memory T-cells and acts directly upon dendritic cells in an antigen-specific manner; ultimately activating mucosal immunity via Tc17 pathways. Antigen-targeted TF enhanced inflammatory response in models against Candida as well as S. aureus. Mass spec data suggests TF is hybrid compound, predicted to containing elements of peptides and nitrogenous bases. Finally, we provide ex vivo human data to demonstrate the therapeutic potential of TF and even attempt to address some of the past’s more fanciful claim. This report represents transfer factors’ resurrection and provides a modern scientific investigation into this once forgotten area of immunology.
High-Accuracy Absolute Length Measurement Using an Optical-Comb Pulsed Interferometer: Verification of Coordinate Measuring Machines (2017)

The optical frequency comb has become a standard for length and frequency measurements. Its pulsed laser can produce temporal coherence interference fringe patterns, and these fringes can be used as the length standard for practical measurement of absolute lengths. This research aims to develop a measuring system for coordinate measuring machine (CMM) verification, which can be used to measure the absolute length of a target in three dimensions. Thus, a spherical target has been considered. A ball lens with a refractive index of 2.0 has been selected as the target for the interferometer in this study. Using the ball lens target, the absolute length can be measured up to 10 m, covering the medium- to large-sized range of CMM applications. The experimental results demonstrate that the measurement uncertainty is smaller than that of the artifact test. In addition, the measurement time of the proposed method is 60% less than that of the artifact-test method.
High level of alpha‐fetoprotein in sera of adult mice (1973)

Abstract Mouse a‐fetoprotein (AFP) was purified by making use of its immunological cross‐reaction with rabbit AFP. A radioimmunoassay, developed for mouse AFP, was used to measure AFP concentrations in the sera of adult mice of different inbred strains. The level of adult mouse AFP was found to be 30–350 ng/ml, which is about 10 times higher than has been reported for humans and rats. An association seems to exist between the high basal level of AFP and the remarkably high incidence of spontaneous hepatomas in mice.
Regional time-density measurement of myocardial perfusion (2003)

The measurement of time-density relationships of the myocardium in studies of Magnetic Resonance perfusion data sets is a clinical technique used in assessing myocardial perfusion. Traditionally, to measure the time-density relationship a physician draws a region on the same 2-D image of the myocardium in sequential cardiac cycles. Throughout multiple cardiac cycles the density changes in this region are measured. A major limitation of this technique is change in anatomy relative to the selected region on the myocardium during consecutive cardiac cycles. This causes measurement errors, which are amplified if the traced region does not encompass the entire myocardial thickness, or includes a boundary exterior to the epicardial or endocardial surface. The technique described in this paper uses approximately the same myocardial region throughout the entire perfusion study, which insures inclusion of the entire endocardial to epicardial region and exclusion of exterior regions. Moreover, this region can be subdivided into smaller regions of interest. This can be accomplished by careful segmentation and reformatting of the data into polar coordinates. This allows sectioning both axially and transaxially through the myocardium permitting regional assessment of perfusion specific values such as maximum and/or the time to reach maximum density. These values can then be illustrated using density-mapped colors or time-density curves. This measurement and display technique may provide enhanced detection and evaluation of regional deficits in myocardial contractility and perfusion.
Collapsed tetragonal phase and superconductivity ofBaFe2As2under high pressure (2010)

High pressure x-ray diffraction and electrical resistance measurements have been carried out on ${\text{BaFe}}_{2}{\text{As}}_{2}$ to a pressure of 35 GPa and temperature of 10 K using a synchrotron source and designer diamond anvils. At ambient temperature, a phase transition from the tetragonal phase to a collapsed tetragonal (CT) phase is observed at 17 GPa under nonhydrostatic conditions as compared to 22 GPa under hydrostatic conditions. The superconducting transition temperature increases rapidly with pressure up to 34 K at 1 GPa and decreases gradually with a further increase in pressure. Our results suggest that ${T}_{C}$ falls below 10 K in the pressure range of 16--30 GPa, where CT phase is expected to be stable under high-pressure and low-temperature conditions.
Comparative analysis of p16/CDKN2, p53 and ras gene alterations in human non-small cell lung cancers, with and without associated pulmonary asbestosis (1996)

To investigate genetic abnormalities in human non-small cell lung carcinomas (NSCLC) associated with pulmonary asbestosis as compared with nou-asbestos linked lung cancers, twenty-nine primary non-small cell lung carcinomas (NSCLC) were examined for genetic abnormalities of p16/CDKN2, p53 and ras genes by single-strand conformation polymorphism analysis of polymerase chain reaction products (PCR-SSCP) and direct sequencing. Ten specimens were obtained from autopsies in which concurrent pulmonary asbestosis was present, while 19 samples were surgical specimens from asbestosis-free patients. K-ras mutations were detected in 10% each of the cancers from both asbestosis and non-asbestosis cases. p16/CDKN2 deletions or mutations and p53 aberrations were demonstrated in 20% and 10% of tumors from asbestosis cases, whereas, 32% and 21% of the cancers, respectively, from asbestosis-free patients were positive. In conclusion, it is suggested that the enhancement of neoplasia in the lung by asbestos is not dependent on suppression of p16/CDKN2 and p53 or ras activation and therefore, that asbestosis may activate alternate tumorigenic pathways in the development of NSCLC.
EFFECT OF MAINTENANCE OF "NORMAL" SKIN TEMPERATURE ON SURVIVAL OF INFANTS OF LOW BIRTH WEIGHT (1964)

Survival rates of premature infants weighing 1,000-1,500 gm at birth were compared in a series of infants placed in a special incubator designed to regulate skin temperature at 36.0°C (96.5°F) by means of infrared radiation and in a group of controls placed in a standard incubator warmed only by circulating air to an ambient temperature of 31.1-32.2°C (88-90°F). Improvement in survival among the babies whose skin temperature was maintained at 36.0°C was significant principally in those infants weighing between 1,251 and 1,500 gm at birth. It is suggested that this increased survival was due to the avoidance of the metabolic stresses consequent to cooling in this group of small infants who lack maturity but who are potentially capable of living when their needs are adequately supplied.
