Testing epoxy composite surfaces for bondability (1991)

Abstract Composite surfaces before and after pretreatment for adhesive bonding have been examined by x‐ray photoelectron spectroscopy (XPS) and the extent of transfer of release agents or other contaminants from release agents, which also were analysed by XPS, was estimated. Composite surfaces were examined also by optically stimulated electron emission (OSEE). Surface analyses were correlated with the strengths of adhesive bonded joints. OSEE shows promise as a non‐destructive method for determining the bondability of epoxy resin matrix composites.

The resonance energies of strange dibaryons are investigated with the use of the $\overline{K}\mathit{NN}\text{\ensuremath{-}}\ensuremath{\pi}YN$ coupled-channels Faddeev equation. It is found that the pole positions of the predicted three-body amplitudes are significantly modified when the three-body coupled-channels dynamics is approximated, as is done in the literature, by the effective two-body $\overline{K}N$ interactions.
Immunohistochemical localization of glandular kallikrein in the endocrine and exocrine human pancreas. (1983)

Fab fragments from two new monospecific anti-human tissue kallikrein sera were examined for their capacity to inhibit the functional activities of purified human urinary kallikrein and purified human pancreatic kallikrein. Fragments from a new anti-urinary kallikrein serum and from an anti-pancreatic kallikrein serum yielded mixed inhibition of kinin-generating activity and minimal inhibition of esterolytic activity. In contrast to the previously described "active site directed" anti-urinary kallikrein, these new antisera demonstrated little specificity for epitopes near the enzymatic site of urinary or pancreatic kallikrein. When used to localize kallikrein antigen in human pancreas obtained at surgery, IgG fractions of the new anti-kallikrein sera yielded moderate acinar and ductal staining in the absence of pretreatment of the tissue with trypsin or pronase. Short incubation with 0.125 mg/ml of either enzyme permitted the discrete localization of islet beta cell kallikrein antigen, while increased pronase concentrations decreased kallikrein antigen in both islets and exocrine tissue and led to islet destruction. Both antibody specificity and tissue preparation influence kallikrein localization in human pancreas.
Occupational exposure to anaesthetics in 20 hospitals (1980)

The nitrous oxide and halothane contamination in the inspired air of anaesthetists and in the atmospheres of operating theatres, anaesthetic induction and recovery rooms, were measured during normal unmodified working sessions in 20 hospitals using integrated personal samplers. The nitrous oxide (and halothane) levels ranged from < 10 to 3000 ppm (< 0.1 to 60 ppm) in the different areas with an average of 388.5 ppm (2.8 ppm) for the inspired air of the anaesthetists during 2 hour sampling periods. There was no correlation between the levels of the anaesthetists' exposures and those in the static air samples and this appeared to be due primarily to a wide variation in work practices and techniques. Thus it is potentially misleading to assess anaesthetists' occupational exposure by collecting ambient air samples in the operating rooms. Comparisons with more prolonged measurements in one hospital indicated that the installation of relatively simple active scavenging devices will be effective in most hospitals.
Isolation, Characterization, Molecular Gene Cloning, and Sequencing of a Novel Phytase from <i>Bacillus subtilis</i> (1998)

The Bacillus subtilis strain VTT E-68013 was chosen for purification and characterization of its excreted phytase. Purified enzyme had maximal phytase activity at pH 7 and 55 degrees C. Isolated enzyme required calcium for its activity and/or stability and was readily inhibited by EDTA. The enzyme proved to be highly specific since, of the substrates tested, only phytate, ADP, and ATP were hydrolyzed (100, 75, and 50% of the relative activity, respectively). The phytase gene (phyC) was cloned from the B. subtilis VTT E-68013 genomic library. The deduced amino acid sequence (383 residues) showed no homology to the sequences of other phytases nor to those of any known phosphatases. PhyC did not have the conserved RHGXRXP sequence found in the active site of known phytases, and therefore PhyC appears not to be a member of the phytase subfamily of histidine acid phosphatases but a novel enzyme having phytase activity. Due to its pH profile and optimum, it could be an interesting candidate for feed applications.
RFID medicine management system (2012)

This study proposes a framework of medicine management system based on the Radio Frequency Identification (RFID). The heavy workloads of the hospital often result in that the nurses give patients the wrong medicine. This situation leads to the patient injury, and even death. In order to improve the quality of health care, this paper integrates the RFID, network and database techniques to develop a graphical medicine management system. In the proposed system, each patient has a RFID tag and each kind of medicine also is encoded to a RFID number. The digital patient information forms contain the medicinal information of each patient. When a nurse gives medicine to a patient, he or she must check the patient's RFID tag and the medicinal number to avoid the situation of taking wrong medicines.
The Use of Electronic Masking in Color Television (1954)

The nature of the "reproducing primaries" employed by most subtractive color processes is such that undesirable cross-coupling exists between the various color separation images originally recorded by the taking sensitivities of the film. When using subtractive color transparencies as original material for color television transmissions, the output signals from the pickup device may be thought of as integral density measurements of the film. If the characteristics of the film are known, it is possible to devise an electrical network which will partially remove the photographic crosscoupling. For some types of subtractive transparencies color television reproduction is subjectively enhanced by this procedure
The Sagnac effect: correct and incorrect explanations (2000)

Different explanations for the Sagnac effect are discussed. It is shown that this effect is a consequence of the relativistic law of velocity composition and that it can also be explained adequately within the framework of general relativity. When certain restrictions on the rotational velocity are imposed, the Sagnac effect can be attributed to the difference in the time dilation (or phase change) of material particle wave functions in the scalar (or correspondingly vector) gravitational potential of the inertial forces in a rotating reference system for counterpropagating waves. It is also shown that all the nonrelativistic interpretations of the Sagnac effect, which are unfortunately sometimes found in scientific papers, monographs and textbooks, are wrong in principle, even though the results they yield are accurate up to relativistic corrections in some special cases.
Wave Devouring Propulsion System: From Concept to Trans-Pacific Voyage (2009)

In the spring of 2008, the Mermaid II began her historic voyage from Hawaii to Japan. According to the log of the vessel, the journey took 110 days and covered about 7800 km. The successful conclusion of the voyage demonstrated the possibility that Wave Devouring Propulsion System (WDPS) could be adapted to practical use. In order to capitalize on the success of this voyage, the author intended to design and tested a new WDPS hull within a year to build it. A WDPS is a thrust generator for a vessel that converts wave forces directly into forward thrust. Additionally it efficiently reduces hull pitch and roll motion, while also performing as a motion stabilizer. The Mermaid II, which is equipped with a WDPS, incorporates a specially designed catamaran hull form and twin hydrofoil system. A solid hydrofoil system that captures wave forces is set on the underside of the bow of the vessel. Those hydrofoils are connected to the hull with pin joints and are supported by soft springs that provide foil pitch restoring force.
Relationship of CD4+CD25+ regulatory T cells to immune status in HIV-infected patients (2005)

Increased T Reg frequencies in peripheral blood were related to low peripheral blood CD4 T-cell counts and polarization toward Th2 immune responses in HIV-infected patients.
Shifts in Peptide and Protein Charge State Distributions with Varying Spray Tip Orifice Diameter in Nanoelectrospray Fourier Transform Ion Cycltron Resonance Mass Spectrometry (2003)

The influence of the diameter of the spray tip employed for nano-electrospray mass spectrometry (nano-ES-MS) upon mass spectral charge state distributions was investigated using angiotensin I (M(r) = 1296), insulin (M(r) = 5774), and ubiquitin (M(r) = 8560) as test analytes. Under a variety of experimental conditions, the charge state distributions of the test peptides and protein consistently shifted toward higher values as the tip orifice diameter decreased. This finding indicates that the use of narrow diameter capillaries can promote the formation of higher charge state ions that are more reactive precursors in tandem mass spectrometry experiments. A detailed comparison of charge state distributions obtained for nanospray capillaries of varying diameters was undertaken while systematically varying experimental parameters such as sample flow rate, analyte concentration, solvent composition, and electrospray current. The general tendency to obtain higher charge states from narrow diameter capillaries was conserved throughout, but tips with smaller orifices were more sensitive to sample flow rate (the average charge state was lowered significantly as flow was raised), whereas tips with bigger orifices were more sensitive to analyte concentration and pH of the solution (as each was lowered, the average charge state increased).
Stretching tethered DNA chains in shear flow (2000)

We discuss the stretching of tethered chains subject to a shear flow. Fluorescence microscopy measurements of the extension of sheared tethered DNA, "model polymers", of various lengths are presented. The tethered chains approach full extension as the flow rate is increased, but very slowly. We show that a general theory to understand the large deformation of any sheared tethered chain must include both the correct nonlinear force-extension relation and chain fluctuations transverse to the flow direction, which themselves depend on the nonlinear elasticity of the chain. Direct comparison of derived scaling laws to simulations and experiments support our theory.
Detection of Phase Variation in Expression of Proteins Involved in Hemoglobin and Hemoglobin-Haptoglobin Binding by Nontypeable <i>Haemophilus influenzae</i> (2000)

Haemophilus influenzae can utilize different protein-bound forms of heme for growth in vitro. A previous study (I. Maciver, J. L. Latimer, H. H. Liem, U. Muller-Eberhard, Z. Hrkal, and E. J. Hansen. Infect. Immun. 64:3703-3712, 1996) indicated that nontypeable H. influenzae (NTHI) strain TN106 expressed a protein that bound hemoglobin-haptoglobin and was encoded by an open reading frame (ORF) that contained a CCAA nucleotide repeat. Southern blot analysis revealed that several NTHI strains contained between three and five chromosomal DNA fragments that bound an oligonucleotide probe for CCAA repeats. Three ORFs containing CCAA repeats were identified in NTHI strain N182; two of these ORFs were arranged in tandem. The use of translational fusions involving these three ORFs and the beta-lactamase gene from pBR322 revealed that these three ORFs, designated hgbA, hgbB, and hgbC, encoded proteins that could bind hemoglobin, hemoglobin-haptoglobin, or both compounds. Monoclonal antibodies (MAbs) specific for the HgbA, HgbB, and HgbC proteins were produced by immunizing mice with synthetic peptides unique to each protein. Both HgbA and HgbB were readily detected by Western blot analysis in N182 cells grown in the presence of hemoglobin as the sole source of heme, whereas expression of HgbC was found to be much less abundant than that of HgbA and HgbB. The use of these MAbs in a colony blot radioimmunoassay analysis revealed that expression of both HgbA and HgbB was subject to phase variation. PCR and nucleotide sequence analysis were used in conjunction with Western blot analyses to demonstrate that this phase variation involved the CCAA repeats in the hgbA and hgbB ORFs.
A high performance liquid chromatographic method for the separation of hexose monophosphates and UDP glucose from plant extracts and its use to determine specific activities in radiotracer experiments (1994)

Abstract Anion exchange high performance liquid chromatography (HPLC) was used to separate UDP glucose (UDPGlc) and hexose monophosphates (HMPs) in crude ethanol extracts of potato tubers. Detection and quantification of UDPGlc and [U‐ 14 C]UDPGlc was achieved with UV (A 254 ) and radioactivity monitors connected in series. The 14 C content in glucose 6‐phosphate (Glc‐6‐P), fructose 6‐phosphate (Fru‐6‐P) and glucose 1‐phosphate (Glc‐1‐P) was obtained following their enzymatic conversion to gluconate 6‐P and subsequent separation by HPLC. Individual HMPs were quantified by enzyme‐coupled reaction systems using a microplate reader equipped with a 340 nm filter. This approach allowed the specific activities of UDPGlc, Glc‐6‐P, Fru‐6‐P and Glc‐1‐P to be quantified in radiolabelled potato extracts within 2 h.
The Tandem β-Zipper Model Defines High Affinity Fibronectin-binding Repeats within Staphylococcus aureus FnBPA (2007)

Binding of the fibronectin-binding protein FnBPA from Staphylococcus aureus to the human protein fibronectin has previously been implicated in the development of infective endocarditis, specifically in the processes of platelet activation and invasion of the endothelium. We recently proposed a model for binding of fibronectin to FnBPA in which the bacterial protein contains 11 potential binding sites (FnBPA-1 to FnBPA-11), each composed of motifs that bind to consecutive fibronectin type 1 modules in the N-terminal domain of fibronectin. Here we show that six of the 11 sites bind with dissociation constants in the nanomolar range; other sites bind more weakly. The high affinity binding sites include FnBPA-1, the sequence of which had previously been thought to be encompassed by the fibrinogen-binding A domain of FnBPA. Both the number and sequence conservation of the type-1 module binding motifs appears to be important for high affinity binding. The in vivo relevance of the in vitro binding studies is confirmed by the presence of antibodies in patients with S. aureus infections that specifically recognize complexes of these six high affinity repeats with fibronectin.
Fault surface detection in 3-D seismic data (2005)

A novel approach to the automatic extraction of geological faults from three-dimensional (3-D) seismic data is described, and qualitative and quantitative comparisons of manually and automatically picked fault geometries interpreted from both high and medium quality 3-D seismic datasets are presented. An algorithm has been developed that allows semiautomated identification, extraction, and modeling of fault surfaces imaged in 3-D seismic datasets. Based on a multistage approach, the algorithm operates initially at a small spatial scale, identifying local discontinuities in the seismic horizons, and then gradually considers larger and larger segments of fault surfaces until a set of complete fault surfaces are identified. A large portion of the work involves merging of segments of fault surfaces, performed using a highest confidence first (HCF) stratagem, taking into consideration the context of the resultant fault geometry. We show that results from the automated fault picker compare favorably with a manually labeled set of faults surfaces interpreted from a high-quality dataset. Last, we present an estimate of the savings in human operator time that can be made by using the automated approach, indicating savings of multiple person-days for the multigigabyte datasets that typify the petroleum industry.
Low Cost Planar Waveguide Technology-Based Dielectric Resonator Antenna (DRA) for Millimeter-Wave Applications: Analysis, Design, and Fabrication (2010)

A compact, low cost and high radiation efficiency antenna structure, planar waveguide, substrate integrated waveguide (SIW), dielectric resonator antennas (DRA) is presented in this paper. Since SIW is a high Q- waveguide and DRA is a low loss radiator, then SIW-DRA forms an excellent antenna system with high radiation efficiency at millimeter-waveband, where the conductor loss dominates. The impact of different antenna parameters on the antenna performance is studied. Experimental data for SIW-DRA, based on two different slot orientations, at millimeter-wave band are introduced and compared to the simulated HFSS results to validate our proposed antenna model. A good agreement is obtained. The measured gain for SIW-DRA single element showed a broadside gain of 5.51 dB,-19 dB maximum cross polarized radiation level, and overall calculated (simulated using HFSS) radiation efficiency of greater than 95%.
N2 and CO2 in the Oil Field: Stimulation and Completion Applications (1986)

Summary The use of both N2 and CO2 in oilfield stimulation treatments dates back more than 20 years.1 Early use was limited, but the past few years have brought about an increase in the use of both, as well as new, unconventional applications of these products.

Formation and electronic properties of In2S3 / Cu(In,Ga)Se2 junctions and related thin film solar cells (2009)

In this work, thermally evaporated In2S3 thin films have been used as buffer layers in Cu(In,Ga)Se2 solar cells. The aim was to prepare and systematically characterise highly efficient solar cell devices without cadmium, determine the factors limiting their performance and suggest ways for future improvements. The state of the art Cu(In,Ga)Se2 solar cell with CdS buffer layer was the starting point for this work and the role of the buffer layer as well as alternative buffer layer concepts are introduced in the beginning. High quality, crystalline In2+xS3 was successfully synthesised and used as reference material for the structural characterisation of In2S3. Three modifications with tetragonal, cubic and trigonal symmetry were identified and characterised with X-ray diffraction (XRD) measurements in the temperature range from 31°C to 1040°C. The utilisation of crystalline, single phase source material and the development of appropriate buffer processing led to high efficiency solar cells. A key process for optimal device performance was post deposition annealing of the completed solar cells for 35min. to 55min. at a temperature of 200 °C. Annealing was found to improve mainly the fill factor and open circuit voltage of devices with an In2S3 buffer. Losses in the spectral response upon annealing at long wavelengths (700-1200 nm) were observed. By the annealing the charge carrier recombination could be reduced and the dominant recombination mechanism gradually changed. As a result of the reduced recombination the open circuit voltage of the ZnO/ In2S3/ Cu(In,Ga)Se2/ Mo devices could be reproducibly increased by 100mV-150mV upon annealing and devices were fabricated with open circuit voltages beyond those of the established CdS/ Cu(In,Ga)Se2 reference cells. Thus, the potential of In2S3 to form high quality junctions with Cu(In,Ga)Se2 could be demonstrated. By a combination of bulk and surface sensitive analysis methods, a pronounced Cu diffusion from the Cu(In,Ga)Se2 absorber into the In2S3 layer could be shown as a result of the annealing. In2S3/ Cu(In,Ga)Se2-bilayer structures were analysed by: (1) high kinetic energy (HIKE) X-ray photoelectron spectroscopy (XPS, (2) standard XPS (3) energy-dispersive X-ray spectroscopy (EDX). All methods gave a clear proof that Cu diffuses into the In2S3 and indicated a solubility limit of 4-9 at.% for Cu in In2S3. Based on the buffer processing developed and the observed Cu diffusion, new record efficiencies (15.2%, FF =75.6%, jSC= 29.8mA/cm2, VOC=677mV) for Cu(In,Ga)Se2 solar cells with an evaporated buffer layer could be obtained.
Investigation of the efficacy of progesterone pessaries in the relief of symptoms of premenstrual syndrome. progesterone Study Group. (1995)

In this study, progesterone, given as pessaries by vaginal or rectal administration, was more effective than placebo in the relief of symptoms of premenstrual syndrome in a population of patients selected by strict entry criteria.
The complement-fixation reaction in eguine infectious anemia: demonstration of inhibition by IgG (T). (1971)

The role of non-complement-fixing anti-equine infectious anemia (EIA) antibody in the conversion of complement fixation (CF) tests from positive to negative in EIA-infected horses was investigated. Complement-fixation inhibition (CFI) tests demonstrated antibodies in sera that were CF negative. These antibodies would bind to antigen, but would not fix complement. The inhibiting antibodies were isolated and shown to be IgG(T) by immunoelectrophoresis and immunodiffusion against monospecific anti-IgG(T) antisera. Separation of immunoglobulins from affected horse sera by DEAE cellulose chromatography revealed 11 of 13 had complement-fixing IgG and non-complement-fixing IgG(T) antibodies present simultaneously regardless of the reactivity of whole sera. The reactivity of whole sera in CF and CFI tests evidently depended upon the relative concentration and perhaps affinity of the Ig classes. The predominant class fluctuated in serial sera from four of six persistently infected horses.
A novel scheme of ROI detection and transcoding for mobile devices in high-definition videoconferencing (2013)

The experience of watching real-time high definition videos on mobile devices is greatly limited due to the screen size, especially when people attend real-time videoconferencing meetings via their smart phones. This issue could be solved by a ROI (Region of Interest) based scalable video transcoding scheme that displays the ROIs with higher quality and other regions in the same video frame. However, currently most researches on ROI based video adaptation focus on VOD streaming applications rather than real-time videoconferencing. This paper presents a novel scheme of ROI detection and transcoding for mobile devices in video-conferencing system that uses a Kinect based approach to detect ROIs and a ROI-enabled transcoding scheme will be used to transcode the video streams by using a re-quantization approach. Experiments shows that with the ROI extraction algorithm and the ROI-enabled transcoding scheme, the bitrate of a video stream can be significantly reduced, while the perceived quality of the video is still good enough.
