Feasibility of assessing rehabilitation status by using foot pressure sensor while walking (2011)

The world is facing the problem of rapid aging. ICT (Information and Communication Technology) is capable of alleviating this problem. Among the technologies available, simple physical sensors will be the key to capturing a variety of information including human vital information even in the home. This will result in creating a new infrastructure or service of Distributed Diagnosis and Home Healthcare. In order to clarify how sensors-based systems can assess the rehabilitation status of people with leg injuries, this paper describes the results of on-going experiments in which a wearable foot pressure sensor is used to capture foot pressure while walking. The results show that rehabilitation progress can be verified by the system and help motivate the subject to continue with rehabilitation.
Characterization of affinity-purified juvenile hormone esterase from Trichoplusia ni. (1987)

Juvenile hormone (JH) esterase was purified greater than 1000-fold in one step from hemolymph and whole larval homogenates from the last larval instar of Trichoplusia ni to give a single diffuse band that migrates at Mr = 64,000 on sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The purification was based on an affinity chromatography procedure that employs trifluoromethyl ketone ligands. Isoelectric focusing of the purified preparations resulted in multiple bands that coincided to all significant hydrolysis of juvenile hormone detected in this manner. Kinetic experiments using optically pure enantiomers of JH II as substrates showed the two main electromorphs of JH esterase from the hemolymph to have apparently identical kinetic parameters as well as a similar capability to distinguish between substrates that differ in the orientation of the epoxide moiety of JH. However, the enzyme could hydrolyze esters lacking the JH structure. The proteins were shown to be monomers and to have asparagine-linked oligosaccharides, most likely of hybrid structure. Immunochemical and other evidence showed that the affinity-purified proteins were responsible for all significant JH esterase activity during periods of rapid esterolysis in vivo.
Control Method of Arc Stabilization in AC/DC Pulsed MIG Welding (2005)

Changes in arc voltage do not always mean fluctuations of arc length in aluminium alloy welding because cathode fall voltage increases with the absence of oxide. In addition, with the absence of oxide cathode spots become concentrated and the current density near the cathode surface becomes high so that the potential gradient there increases. After the breaking of a short circuit at electrode positive polarity cathode spots are formed on the centre of weld pool surface where little oxide exists. As a result, arc voltage becomes abnormally high in spite of the short arc length. Moreover, when polarity is switched from electrode positive to electrode negative right after the detachment of a droplet, cathode spots are formed on the surface of remained melt metal at the wire tip where little oxide exists so that arc voltage also becomes abnormally high. The arc becomes unstable when those abnormal arc voltages are included in the feedback signal for arc length control. Therefore, a digital filter is developed to obtain correct arc length information by eliminating those abnormal arc voltages from the feedback arc voltage.The algorism of arc length control system is another important factor that affects arc stability. A new algorism is developed to monitor continually the feedback arc voltage of the present pulse cycle and to determine the right timing to terminate the base duration of the present pulse cycle. By using this algorism the average current and average voltage of every pulse cycle plot a line with a decreasing characteristic called pulse V-I characteristic. The inclination of the pulse V-I characteristic can be set freely and controlled accurately. Arc stability is improved by optimisation of the inclination in AC or DC pulsed MIG welding. Furthermore, low frequency modulated AC pulsed MIG welding process is developed by setting two pulse V-I characteristics and switching between them periodically at a low frequency.
Novel optoelectronic fibers codrawn from conducting, semiconducting and insulating materials (2005)

We report on the first successful fabrication of functional optoelectronic devices using fiber drawing techniques. The metal-insulator-semiconductor optical fibers have led to the creation of two prototype fiber structures: A fiber photodetector, and a dual electron-photon transport fiber.
A Systematic Review on the Use of Fibrin Glue for Peripheral Nerve Repair (2011)

Although the majority of the reviewed studies employed animal models, most indicated that the performance of fibrin glue was equal, if not superior, to that of microsuturing when repairing peripheral nerves. Overall, many authors reported that fibrin glue was a quicker and easier modality to use than microsuture repair. There is, however, not a single well-controlled human trial assessing the efficacy of fibrin glue in relation to that of suturing techniques.
Degradable Metal for Use in a Fully Dissolvable Frac Plug (2016)

Abstract A new dissolvable frac plug has been developed for "plug-and-perf" style hydraulic fracturing applications. The dissolvable frac plug operates like a traditional frac plug and can be set anywhere in the wellbore to isolate individual zones. The new dissolvable frac plug is composed of a high-strength metal that degrades completely in wellbore fluids. Traditional frac plugs are constructed from a composite material. After a hydraulic fracturing treatment is complete, traditional frac plugs create a restriction to production flow and must be removed. Thus, a separate intervention is required to mill out traditional plugs after fracturing. A novel dissolvable frac plug has been developed that eliminates the need for a separate mill run intervention into the wellbore. The new frac plug will degrade completely to leave an unrestricted wellbore for production. The high-strength dissolvable metal allows dissolution in water-based wellbore fluid, formation fluid, or production fluid. Comprehensive laboratory testing was conducted on the dissolvable metal alloy for the new dissolvable frac plug. The dissolvable metal alloy is a metallic alloy that is combined with a dopant. The dissolution behavior is controlled by the interaction between the dopant and the rest of the metal alloy. Metallographic analysis illustrated the effect of the dopant on the dissolution of the metallic alloy. Dissolution is further influenced by the wellbore temperature. The high-strength alloy allows for the creation and use of dissolvable slips, which enables the complete dissolution of a frac plug that can be set anywhere within the wellbore. The novel frac plug is designed for plug-and-perf applications and is composed of a new high-strength engineered metal that dissolves in water-based wellbore fluid, formation fluid, or production fluid. Complete dissolution of the frac plug eliminates the need for a separate mill run intervention into the wellbore, which helps reduce costs, operation time, and risks to personnel. This paper discusses the development of the dissolvable metal and the dissolution behavior of the metal upon exposure to wellbore fluids.
TiN from TiO2 via cycling microwave (2002)

TiO 2 powders from a variety of commercial sources were used to synthesize TiN powders using a microwave-induced self-burning cyclical process. The origin and size of the stoning TiO2 precursor powder had a significant effect on the final morphology and particle-size distribution of the TiN powders produced.
Copy-number changes in evolution: rates, fitness effects and adaptive significance (2013)

Gene copy-number differences due to gene duplications and deletions are rampant in natural populations and play a crucial role in the evolution of genome complexity. Per-locus analyses of gene duplication rates in the pre-genomic era revealed that gene duplication rates are much higher than the per nucleotide substitution rate. Analyses of gene duplication and deletion rates in mutation accumulation lines of model organisms have revealed that these high rates of copy-number mutations occur at a genome-wide scale. Furthermore, comparisons of the spontaneous duplication and deletion rates to copy-number polymorphism data and bioinformatic-based estimates of duplication rates from sequenced genomes suggest that the vast majority of gene duplications are detrimental and removed by natural selection. The rate at which new gene copies appear in populations greatly influences their evolutionary dynamics and standing gene copy-number variation in populations. The opportunity for mutations that result in the maintenance of duplicate copies, either through neofunctionalization or subfunctionalization, also depends on the equilibrium frequency of additional gene copies in the population, and hence on the spontaneous gene duplication (and loss) rate. The duplication rate may therefore have profound effects on the role of adaptation in the evolution of duplicated genes as well as important consequences for the evolutionary potential of organisms. We further discuss the broad ramifications of this standing gene copy-number variation on fitness and adaptive potential from a population-genetic and genome-wide perspective.
<title>Electronically gated multiemitter x-ray source for high-speed tomography</title> (1999)

High speed X-ray tomography is being developed for on-line measurement of multiphase flow for well management in the oil industry. To reduce motion artifacts to acceptable levels a source is required that can scan about a 100 mm diameter pipe in approximately 20 ms, thus rendering a rotating source an impractical solution. In order to achieve a spatial resolution of 2 mm in the reconstructed image a total of 105 individual projections over a 210 degree arc are required. The large number of point sources means individual X-ray tubes are not practicable. Our solution is to use multiple electron beams where the active focal spot can be rapidly scanned across the target in an arc about the pipe with the use of electronic grids. This paper describes a prototype of such a tube designed, in the first instance, to cover a 30 degree arc and consisting of 13 individual emitters. Having proved the principle of operation a full system is now in the design stage and shall be briefly discussed.
Methodological issues related to antifungal drug interaction modelling for filamentous fungi (2002)

Given the high mortality of invasive infections caused by filamentous fungi and the limitations of current antifungal therapies, the interest in combination therapy is increasing. However, assessment of the nature and the intensity of antifungal interactions depends on the in vitro methodology used as well as on the approach chosen to analyse the data. Regarding in vitro methodology, despite the considerable progress that has been made with the M-38P standard proposed by the National Committee Clinical Laboratory Standards (NCCLS), many variables in antifungal susceptibility testing of filamentous fungi such as the inoculum, incubation conditions, medium and minimal inhibitory concentration (MIC) endpoints remain unstandardized. Visual determination of the MIC is subjective and does not allow precise quantification of fungal growth, thus hindering the modelling of the concentration-dependent effects of antifungal drugs on filamentous fungi. Colorimetric assays based on the conversion of tetrazolium salts may help to overcome these problems and enable the development of modern approaches to modelling the interaction of antifungal drugs with moulds. Regarding the modelling of drug interactions, various models have been developed based on non-parametric and parametric approaches of the two main competitors – the Loewe additivity and the Bliss independence – to the zero interaction theory. The standard approach in medical microbiology has been the calculation of a fractional inhibitory concentration index but this appears not to be suitable for moulds. Alternative approaches of drug interaction modelling consist of response surface approaches and fully parametric models which incorporate modern concepts of statistical and regression analysis and provide an objective and quantitative tool for the study of drug interaction.
Circuit synthesis based on VHDL language transformations (2003)

One of the major problems within the VHDL based system synthesis is to start the design on a higher abstraction level than the register transfer level (RT-level). We present a novel synthesis procedure called SYLANT (Synthesis based on Language Transformations), which uses the methodology of high level synthesis. It starts from the abstract high-level functional model and produces an RT-level description through successive language transformations. The major advantage of this method is that neither a data-flow graph, nor any meta-language as internal representation is used, only the standard VHDL, This internal VHDL representation is accessible to the designer, and the circuit model can be simulated after each step during the synthesis flow. Different algorithms can be implemented for any step, and depending on the applied technology dependent information, various RT-level architectures can be obtained. The output VHDL format is suitable for continuing the design flow with RT-level based synthesis tools.
Steroid-induced accumulation of lipid in the osteocytes of the rabbit femoral head. A histochemical and electron microscopic study. (1985)

A high dose of methylprednisolone was administered intramuscularly to rabbits, and we studied the accumulation of lipid in the osteocytes of the femoral head by histochemical methods and electron microscopy. Advanced hyperlipidemia and a fatty liver were observed in four weeks. Electron microscopy was used to define the ultrastructural changes in osteocytes, which showed small lipid droplets that gradually enlarged, finally resulting in the formation of vacuolated vesicles. An increase in the size of the lipid droplets caused them to compress the nucleus to one side of the lacuna, resulting in discontinuities of the cell membrane followed by cell disintegration. These observations demonstrate the effect on osteocytes of a disturbance in lipid metabolism caused by the administration of large doses of steroids.

Serum Parathyroid Hormone Concentrations in Senile Dementia (alzheimer's Disease) (1980)

The accumulation of aluminum in the cerebral cortex has been implicated as a factor in the pathogenesis of Alzheimer type senile dementia (SD) and in the dialysis dementia found in patients with chronic renal failure on long-term intermittent hemodialysis treatment. In animal studies, parathyroid hormone (PTH) produces increased absorption of aluminum from the gastrointestinal tract and elevations of aluminum in the cerebral cortex. It has been proposed that PTH elevations may increase tissue aluminum loads in patients with senile dementia. The present study was undertaken to investigate the status of circulating PTH in patients with SD and age/sex matched controls. No significant differences were found between these groups. Elevated PTH (when it did occur) seemed to be related to the degree of renal impairment rather than dementia. Differences in the distribution of aluminum in patients with dialysis dementia and SD are discussed.
Highly Efficient and Thermally Stable Blue-Emitting AlN:Eu<sup>2+</sup> Phosphor for Ultraviolet White Light-Emitting Diodes (2009)

An Eu2+-activated AlN phosphor was synthesized by firing the powder mixture of AlN, α-Si3N4, and Eu2O3 at 1500−2050 °C for 4 h under 1.0 MPa N2. The phase purity, photoluminescent properties, thermal quenching, and quantum efficiency of the fired samples were investigated. A single AlN wurtzite phase was formed at low doping concentrations of Eu2+ (≤0.1 mol %) and Si (≤2.2 mol %). The introduction of Si is essential for the solubility of Eu2+ in the AlN lattice. Intense blue luminescence with a peak emission wavelength of 465 nm was observed in AlN:Eu2+, when Si was doped simultaneously. This blue phosphor shows a small thermal quenching, retaining the luminance of 90% at 150 °C. The absorption and external quantum efficiencies of AlN:Eu2+ are 63%μ and 46% upon 365 nm excitation, respectively. These results indicate that AlN:Eu2+ has great potential as a blue phosphor for white light-emitting diodes (LEDs) utilizing UV chips as the light source.
Immunological identification of A<sub>1</sub> adenosine receptors in brain cortex (1995)

The A1 adenosine receptor from pig brain cortex has been identified by means of two antipeptide antibodies against two domains of the receptor molecule: PC/10 antiserum was raised against a part of the third intracellular loop, and PC/20 antiserum was raised against a part of the second extracellular loop. PC/10 antibody was able to recognize a 39-kDa band that corresponded to the A1 receptor, as demonstrated by immunoblotting and by immunoprecipitation of the molecule cross-linked to [125I](R)-2-azido-N2-p-hydroxy(phenylisopropyl)adenosine. Besides the 39-kDa band, PC/20 also recognized a 74-kDa form that does not seem to correspond to a receptor-G protein complex. The occurrence of the two bands was detected and analyzed in samples from different species and tissues showing a heterogeneous distribution of both. The 74-kDa form can be converted into the 39-kDa form by treatment with agonists or antagonists of A1 adenosine receptors. These results suggest that A1 adenosine receptor can occur in dimers and that the dimer-monomer conversion might be regulated by adenosine as the physiological ligand. Since the 74-kDa aggregates were not recognized by PC/10, it is likely that part of the third intracellular loop participates in the protein-protein interaction.
Blood pressure regulation V: in vivo mechanical properties of precapillary vessels as affected by long-term pressure loading and unloading (2013)

Recent studies are reviewed, concerning the in vivo wall stiffness of arteries and arterioles in healthy humans, and how these properties adapt to iterative increments or sustained reductions in local intravascular pressure. A novel technique was used, by which arterial and arteriolar stiffness was determined as changes in arterial diameter and flow, respectively, during graded increments in distending pressure in the blood vessels of an arm or a leg. Pressure-induced increases in diameter and flow were smaller in the lower leg than in the arm, indicating greater stiffness in the arteries/arterioles of the leg. A 5-week period of intermittent intravascular pressure elevations in one arm reduced pressure distension and pressure-induced flow in the brachial artery by about 50%. Conversely, prolonged reduction of arterial/arteriolar pressure in the lower body by 5 weeks of sustained horizontal bedrest, induced threefold increases of the pressure-distension and pressure-flow responses in a tibial artery. Thus, the wall stiffness of arteries and arterioles are plastic properties that readily adapt to changes in the prevailing local intravascular pressure. The discussion concerns mechanisms underlying changes in local arterial/arteriolar stiffness as well as whether stiffness is altered by changes in myogenic tone and/or wall structure. As regards implications, regulation of local arterial/arteriolar stiffness may facilitate control of arterial pressure in erect posture and conditions of exaggerated intravascular pressure gradients. That increased intravascular pressure leads to increased arteriolar wall stiffness also supports the notion that local pressure loading may constitute a prime mover in the development of vascular changes in hypertension.

Falling Sphere Viscometry. I. Wall and Inertial Corrections to Stokes' Law in Long Tubes (1973)

The classical expression for determining viscosity from sphere fall velocity is Stokes' law. Stokes' law applies in the absence of wall and inertial effects. In the usual experimental apparatus there are wall effects and there may be inertial effects. The objective of this paper is to establish a correlation of wall and inertial corrections to Stokes' law in the range appropriate for falling sphere viscometry, and to present this correlation in a manner convenient for application. The desired correlation is presented in Table II and Figure 5 of the text. The new correlation should be useful in determining the viscosity of Newtonian fluids and in determining the zero shear rate viscosity of polymer solutions.
Optical coherence refractometry (2008)

We introduce a novel approach to refractometry using a low coherence interferometer at multiple angles of incidence. We show that for plane parallel samples it is possible to measure their phase refractive index rather than the group index that is usually measured by interferometric methods. This is a significant development because it enables bulk refractive index measurement of scattering and soft samples, not relying on surface measurements that can be prone to error. Our technique is also noncontact and compatible with in situ refractive index measurements. Here, we demonstrate this new technique on a pure silica test piece and a highly scattering resin slab, comparing the results with standard critical angle refractometry.
