Influence of soluble surfactants on the motion of a finite bubble in a capillary tube (1992)

The steady motion of a long inviscid bubble displacing a viscous fluid in a capillary tube was first analyzed by Bretherton [J. Fluid Mech. 10, 166 (1961)] in the limit of small capillary number (Ca). While his theoretical prediction for the wetting film thickness left behind the moving front of the bubble showed good agreement with experimental observations for a moderately small Ca, it underpredicted the film thickness when Ca was smaller than about 10−4. In an attempt to resolve this discrepancy, several investigators studied the Marangoni effects of surface contaminants and predicted that the film thickness could be increased by a maximum factor of 42/3 if the surfactant transport is bulk-diffusion controlled. This prediction, however, is limited to the case of a semi-infinitely long bubble. The present study examines the motion of a finite length bubble in the presence of a small amount of surfactants. Both front and rear ends of the bubble are analyzed in the limit of small capillary number. The results indicate that due to the accumulation of the surfactant at the rear end of the bubble, the film thickening effect of the surfactant occurs only when the bubble length is larger than a certain critical value. It is also shown that the total pressure drop to drive the finite bubble through the capillary tube increases linearly with the length of the bubble as long as the bubble length is smaller than the critical value. When the bubble is longer than the critical value, the pressure drop does not increase any longer but remains to be constant. It appears that these results are capable of explaining the experimental observations of Schwartz and co-workers [J. Fluid Mech. 127, 259 (1986)] in which the film-thickening behavior at low Ca was shown to be dependent on the bubble length.
Purification and properties of a mammalian endonuclease showing site-specific cleavage of DNA. (1981)

An endonuclease activity has been identified from a variety of mammalian sources which cleaves native viral DNAs (adenovirus-2, SV40) and mammalian repetitive DNA to yield specific, double-stranded DNA segments when the cleavage products are analyzed by gel electrophoresis.The activity has been purified 750- fold from bull testes by ammonium sulfate precipitations and ion exchange chromatography.The enzyme has a pH optimum of 7.5 and shows an absolute requirement for M&' or Mn2+ and reducing agents in the reaction buffer.It is strongly inhibited by salt and stimulated by glycerol or dimethyl sulfoxide.By glycerol gradient analysis it has a sedimentation coefficient of 4.5 S (65,000 daltons if globular) and it may exist as a dimer of 6.4 S (130,000 daltons).The enzyme liberates 3'-OH and 5'-P termini in its cleavage of mammalian viral and repetitive DNAs and there is a clear nonrandomness in the 5'-terminal nucleotides: purines and 5'-pG in particular predominate.The similarities between the mammalian endonuclease activity and the bacterial restriction enzymes may be superficial.By gel electrophoresis the mammalian endonuclease produces its most characteristic series of segments with viral DNAs in the molecular weight range of 1.5 X lo5 to 1.5 X 10'.These are true doublestranded intermediate products in the cleavage of high molecular weight DNA but they are not end products in the reaction as they would be in the case of the bacterial restriction enzymes.With time, the endonuclease degrades viral DNA to shorter and shorter segments without releasing acid-soluble nucleotides at any stage in the digestion and the final end products are about 120 base pairs long.The enzyme degrades both double-and single-stranded DNA endonucleolytically though it shows site specificity (production of discrete segments upon gel electrophoresis) only with the double-stranded DNA substrates. ~~Endonucleases have been implicated in a wide variety of prokaryotic and eukaryotic cellular processes including nucleic acid replication (l), repair (2), processing (3), and recombination (4), but until recently endonucleases with site specificity (the restriction enzymes) have been described only in prokaryotes (5).Recently, a n endonuclease with apparent site specificity was described in the unicellular, eukaryotic alga Chlamydomonas reinhardi (6).This is an activity which,
Frequency Tuning in Inductive Power Transfer Systems (2020)

Inductive power transfer systems (IPTSs) systems are equipped with compensation networks that resonate at the supply frequency with the inductance of the transmitting and receiving coils to both maximize the power transfer efficiency and reduce the IPTS power sizing. If the network and coil parameters differ from the designed values, the resonance frequencies deviate from the supply frequency, thus reducing the IPTS efficiency. To cope with this issue, two methods of tuning the IPTS supply frequency are presented and discussed. One method is aimed at making resonant the impedance seen by the IPTS power supply, the other one at making resonant the impedance of the receiving stage. The paper closes by implementing the first method in an experimental setup and by testing its tuning capabilities on a prototypal IPTS used for charging the battery of an electric vehicle.
Preparation and characterization of Fe-doped TiO2 nanoparticles as a support for a high performance CO oxidation catalyst (2012)

A simple method is described for the preparation of Fe-doped TiO2 nanoparticles (Ti1−xFexO2) that can be used as a high performance support material for a CO oxidation catalyst. The method allows one to fabricate Ti1−xFexO2 with uniform sizes and shapes. Microstructural studies using XRD, Raman spectroscopy and EPR analyses indicate that the Fe dopant is substitutionally incorporated by replacing Ti4+ cations. Electrochemical results indicate that, when a small amount of Fe molecules (less than 8 atomic%) are incorporated into a TiO2 structure, the support material has greatly improved redox characteristics. This suggests that an Fe-doped TiO2 support enhances both the release and uptake of oxygen atoms from the catalysts, thus resulting in a high catalytic activity in CO oxidation reactions. The results confirmed that a Au catalyst supported on Fe-doped TiO2 containing a 6 atom% Fe dopant showed an outstanding oxidation performance. The findings reported herein represent an innovative route to designing high performance catalysts for oxidation reactions.
Hybrid Holographic-Digital Processing System For Three-Dimensional Displacement Measurement (1987)

Holographic interferometry in Fourier plane allows 3D displacement measurement from one recording, with fringe localization in Fourier plane and with the interpretation of only two type of fringe patterns. The measuring range can be controlled by the parameters of the Fourier lens and covers units to hundreds micrometers. Such a Fourier holographic processor with real-time recording is very suitable for interfacing to a computer image processor which works for automatic interpretation of the holographic interferograms and precise measurement.

Base Stable Pyrrolidinium Cations for Alkaline Anion Exchange Membrane Applications (2014)

The synthesis and characterization of pyrrolidinium cation based anion exchange membranes (AEMs) are reported. Pyrrolidinium cations with various N-substituents (including methyl, ethyl, butyl, octyl, isopropyl, 2-hydroxylethyl, benzyl, and cyclohexylmethyl groups) were synthesized and investigated with respect to their chemical stability in alkaline media. The influence of substitutions on alkaline stability of pyrrolidinium cations was investigated by quantitative 1H nuclear magnetic resonance spectroscopy (NMR) and theoretical approaches. N,N-Ethylmethyl-substituted pyrrolidinium cation ([EMPy]+) exhibited the highest alkaline stability in this study. The synthesized AEMs based on [EMPy]+ show promising alkaline stability in strongly basic solution. The study of this work should provide a feasible way for improving the alkaline stability of pyrrolidinium cation based AEMs.
Calibrating Microscopic Car-Following Models for Adaptive Cruise Control Vehicles: Multiobjective Approach (2020)

Adaptive cruise control (ACC) vehicles are the first step toward comprehensive vehicle automation. However, the impacts of such vehicles on the underlying traffic flow are not yet clear. Therefore, it is of interest to accurately model vehicle-level dynamics of commercially available ACC vehicles so that they may be used in further modeling efforts to quantify the impact of commercially available ACC vehicles on traffic flow. Importantly, not only model selection but also the calibration approach and error metric used for calibration are critical to accurately model ACC vehicle behavior. In this work, we explore the question of how to calibrate car-following models to describe ACC vehicle dynamics. Specifically, we apply a multiobjective calibration approach to understand the trade-off between calibrating model parameters to minimize speed error versus spacing error. Three different car-following models are calibrated for data from seven vehicles. The results are in line with recent literature and verify that targeting a low spacing error does not compromise the speed accuracy whether the opposite is not true for modeling ACC vehicle dynamics.
miRNA regulated pathways in late stage murine lung development (2013)

MiRNAs are differentially regulated across time and between sexes during the canalicular and saccular stages of lung development. Sex-associated differential miRNA expression may regulate the differences in structural and functional male and female lung development, as shown by networks generated using in silico analysis. These data provide a valuable resource to further enhance the understanding of miRNA control of lung development and maturation.
Overexpression of vinculin suppresses cell motility in BALB/c 3T3 cells (1992)

The content of vinculin, a cytoplasmic protein found in focal contacts and cell-cell junctions, was increased in BALB/c 3T3 cells by gene transfection. The vinculin expressed from the full length chicken cDNA, incorporated into focal contacts and its pattern was identical to that of the endogenous protein. Cells stably expressing vinculin by 20% over the endogenous level had altered locomotory properties. In these cells, the ability to migrate into a wound formed in a confluent monolayer and the locomotion of individual cells were drastically reduced. The results provide direct evidence that cell locomotion can be regulated by modulating vinculin expression.
Value Allocation in Regional Shopping Centers (1998)

Understanding consumer shopping patterns is essential in estimating the value of regional shopping centers. Consumer shopping behavior determines retail sales at regional shopping centers which, in turn, impacts shopping center rents and value. This article quantifies the effects of consumer shopping behavior on nonanchor tenant sales in regional shopping centers. The results of this study reveal that the effects of location, comparison shopping, and department store image are important in estimating shopping center patronage and retail sales. They also indicate that the value of a mall can be allocated to real estate and non-real estate value.
The Clinical Significance of Positive Blood Cultures: A Comprehensive Analysis of 500 Episodes of Bacteremia and Fungemia in Adults. II. Clinical Observations, with Special Reference to Factors Influencing Prognosis (1983)

Among 500 patients with bacteremia and fungemia, total mortality was 42%; about half of all deaths were attributable directly to infection. Mortality increased with age, but deaths unrelated to infection itself were responsible in part for this increase. Mortality was 2.6% among obstetric-gynecologic patients, 42% among medical patients, 49% among surgical patients, and 60% among transplant patients. The risk of death was especially high with enterococcal, facultative gram-negative, fungal, polymicrobial, or hospital-acquired sepsis; in the presence of shock, leukopenia, absolute granulocytopenia, or defined predisposing conditions (neoplasia, cirrhosis, and combinations of factors such as surgery and renal failure); and with a primary infected focus in the respiratory tract, the skin, a surgical wound, an abscess, or an unknown site. Body temperature was inversely related to mortality. Survival was increased by the use of appropriate antibiotics and, where applicable, additional therapeutic maneuvers (e.g., drainage). Multivariate analysis defined seven variables that independently influenced outcome: microorganism, blood pressure, body temperature, primary focus of infection, place of acquisition of infection, age, and predisposing factors. Although some adverse prognostic factors are not amenable to intervention, prevention of nosocomial bacteremia and fungemia and early reversal of hypotension may reduce the death rate from sepsis.
The Magnetic Properties of Nd-Fe-B Melt-Spun Ribbons with Lower Nd Content (1993)

Present work describes the magnetic properties of Nd-Fe-B melt-spun ribbons which have lower Nd content than the Nd2Fe14B compound. The studied alloys were (1) NdxFe94-xB6, (2) (Fe3B)1-x-(Nd2Fe14B)x and (3) Fe1-x-(Nd2Fe14B)x. The grain refinement were underwent by studying the conditions of annealing for crystallization. It results in disappearing noticeable knicks in the demagnetization curves, which is attributed to precipitations of α-Fe and Fe3B phases. The Nd8Fe86B6 melt-spun ribbon annealed at 650°C for 30 min exhibits the highest (BH)max of 126kJm-3(15.8MGOe). The V addition is effective for improving the coercivity.
[Surgical treatment for clinical stage II and III small cell lung cancer patients]. (2006)

To evaluate a surgical resection in multidisciplinary treatment for clinical stage (c-stage) II and III small cell lung cancer (SCLC) patients, we examined the postoperative prognosis concerning in 18 patients who underwent complete surgical resection. Five-year survival rate of 8 c-stage II and 10 c-stage III patients showed 62.5% and 46.7%, respectively. Of these, 7 patients underwent preoperative induction chemotherapy resulting in down-staging to c-stage 0-I, and their survival rate at 5 years after sugery was as good as 68.6%. However, in 4 (57.1%) of 7 patients, tumor cells proved to be alive by pathological assessment of lymph nodes. As a consequence, it was suggested that surgery for c-stage II and III SCLC patients is a meaningful treatment considering their prognoses. In particular, even though the patients show a favorable response of preoperative chemotherapy, to completely eliminate remnant tumor cells, a surgical resection may be necessary.
Current Status and Perspective for Seismological Studies on the Mantle and Core Conducted in Japan (2009)

New global and Japanese seismic projects have promoted the seismological studies of deep Earth structure in Japan. Global and regional upper mantle structures have been extensively elucidated toward a finer scale. The mantle transition zones beneath cold subducted slabs and hot upwellings are widely investigated with new seismic experiments. The lower mantle and D” structures are examined with a global tomography and regional seismic arrays. Comparing to the mantle studies, the core studies are still inactive in Japan. Although seismic data increases, the geographical coverage is still uneven or the gap rather widens. New and challenging seismic experiments are required to overcome the previous achievements. In order to construct an interesting scientific plan, we need new points of view for the Earth dynamics collaborating with the other disciplines.
Glycosylation, Disulfide Bond Formation, and the Presence of a WSXWS-Like Motif in the Orf Virus GIF Protein Are Critical for Maintaining the Integrity of Binding to Ovine Granulocyte-Macrophage Colony-Stimulating Factor and Interleukin-2 (2005)

ABSTRACT Orf virus (ORFV), the type species of the family Parapoxviridae , encodes a protein (GIF) that binds and inhibits the ovine cytokines granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-2 (IL-2). There is no obvious sequence homology between the ORFV protein and any known mammalian GM-CSF- or IL-2-binding proteins. We demonstrate here that many of the biochemical properties of mammalian GM-CSF receptors that are required for efficient binding of GM-CSF are also critical to the GIF protein for binding to ovine GM-CSF (ovGM-CSF). Site-directed mutagenesis of the GIF protein demonstrated, first, the importance of disulfide bonds, and second, that a sequence motif (WDPWV), related to the WSXWS motif of the type 1 cytokine receptor superfamily, was necessary for biological activity. Finally, glycosylation of the GIF protein was also critical for binding to GM-CSF.

<I>In-Situ</I> Deposition of Iron Oxide Nanoparticles on Polyacrylonitrile-Based Nanofibers by Chemico-Thermal Reduction Method (2010)

Polyacrylonitrile (PAN)-based nanocomposite fibers were prepared by co-precipitation of different amounts of Fe(II) and Fe(III) in an alkaline medium to get iron oxide impregnated nanofibers. Nanofibers web were prepared from blend solution of PAN containing different concentrations (1, 2 and 3 wt%) of ferrous (Fe2+)/ferric (Fe3+) solution in the 1:2 molar ratio in an effort to further improvement of the porosity and thereby, electrical properties. Electrospun fibers containing various concentrations of iron salts were then treated with KOH solution to produce nanosized magnetite particles in situ within the PAN nanofibers by precipitating Fe2+ ions or mixture of Fe2+ and Fe3+ ions. Such nanoscale particles homogeneously dispersed in PAN nanofibers to form the three-dimensional network structure. The homogeneously dispersed nanoparticles of iron oxide in and on the PAN carbon nanofibers produced the network structure of reasonably well-aligned configuration. Composite nanofibers morphologies and surface properties were discussed utilizing the combined techniques viz., field emission scanning electron microscope (FE-SEM), particle size analyzer, surface area and pore size distribution measurements.

Synthesis and Electrochemical Properties of Nano–Micro Spherical β-Ni(OH)<sub>2</sub> with Super High Charge–Discharge Speed (2012)

A spherical β-Ni(OH)2 product with nano–micro structure was synthesized by a new controllable crystallization complexation precipitation method. The results show that the nano–micro spherical Ni(OH)2 possesses superior electrochemical properties due to its own nano–micro structure. Furthermore, the new samples of cobalt-doped, zinc-doped, and cobalt–zinc codoped Ni(OH)2 with nano–micro structure were also synthesized. The electrochemical properties of these four nano–micro spherical Ni(OH)2 samples were investigated by galvanostatic charge–discharge and cyclic voltammetric (CV) tests. The electrochemical experimental results indicate that the diffusivity of proton of the doped Ni(OH)2 samples is significantly improved as compared with the pure Ni(OH)2 sample. The Co–Zn codoped Ni(OH)2 sample offers a high discharge specific capacity of 257 mA h g–1 and a long life of more than 800 cycles at a super high charge–discharge speed of 50 C, and the charging time of the product is as short as to 1.2 min.

Methylphenidate for fatigue in advanced cancer: A prospective open-label pilot study (2001)

Psychostimulants such as methylphenidate are used for fatigue in cancer patients. We report a prospective, open-label, pilot study of the successful use of methylphenidate to treat fatigue in nine of 11 consecutive patients with advanced cancer. Seven had received radiation or chemotherapy, a median of three weeks (range from one to 30 weeks) prior to methylphenidate. A rapid onset of benefit was noted, even in the presence of mild anemia. Sedation and pain also improved in some. Only one patient had side effects severe enough to stop the medication.
Design small size of High Frequency (HF) helical antenna (2009)

The main objective of this paper is to focus on the designing of helical antenna in the High Frequency (HF) range from 3 MHz to 30 MHz. Several parameters dimension and helical's profiles were studied in order to obtained a suitable resonance frequency. Among the helical antenna parameters that being studied were on its different forms that link to multiple diameters, radius ratio, and number of turns. The software used for the simulation is the CST Microwave Studio (CST MWS) which is an analytical tool that provides an accurate 3D EM simulation results for high frequency design. The helical antenna was constructed, enables the comparison of results to be analyzed. From the design, the “return losses” were obtained
