[Cortexin effectiveness in circulatory encephalopathy]. (1999)

A clinical trial of cortexin, a new peptide bioregulator of cerebral functions, in combined therapy of dyscirculatory encephalopathy (DE) stage I-II was made in 76 patients. They were divided into two groups: a control group of 31 patients on standard therapy and the study group of 45 patients on standard therapy with adjuvant cortexin delivered via nasal electrophoresis (NE). The effect was estimated by clinical symptoms, psychophysiological tests, computed EEG, quantitative parameters of rehabilitation. Cortexin NE produced a positive effect on psychoemotional state, neurological status, intellectual-mnestic and CNS functions. Adjuvant cortexin aroused efficiency of rehabilitation in DE stage I and II by 22.7%. The response of intellectual-mnestic and CNS functions was the highest. Cortexin improves attention, perception, memory, thinking, cortical neurodynamic processes. It is well tolerated and has no side effects. Cortexin is recommended as a drug of choice in combined treatment of patients with DE stage I-II.
Design of a high signal to ratio electrical impedance plethysmograph (2002)

The authors describe a high-sensitivity impedence plethysmograph for determining the blood pressure of pigeons. The method described can be used for the study of human atherosclerosis. An instrument which increases the signal-to-noise ratio, therefore increasing the sensitivity, was designed. The signal obtained from the subject being tested consists of an amplitude modulated waveform with an index of modulation on the order of 0.1%. This instrument reduces the carrier amplitude in the amplitude modulated (AM) waveform and amplifies the signal before demodulation. The AM signal is then demodulated and any DC offset present is balanced out. The result is an increase in the index of modulation and a higher signal-to-noise ratio at the output.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Instantaneous speed detection with parameter identification for AC servo systems (1992)

Two methods adopting advanced control technology in order to improve the performance of AC servo systems are described. The first method is the detection of instantaneous speed using an observer. This method provides good response in speed control because it is possible to detect exactly the speed without detection dead time over a wide range of speeds. The second method is the identification of the mechanical inertia time corresponding to motor and load based on the model reference adaptive control system. This method enables the instantaneous speed detection to be applied to systems in which the mechanical inertia time is unknown. Moreover, it can realize the automatic adjustment of a speed controller using the result of identification. The effectiveness of these methods has been confirmed by experimentation. The experimental system is composed of a digital controller with a digital signal processor, a PWM inverter, and a permanent magnet motor.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Spatially Variable Advection Correction of Radar Data. Part I: Theoretical Considerations (2010)

Abstract Radar data–based analysis products, such as accumulated rainfall maps, dual-Doppler wind syntheses, and thermodynamic retrievals, are prone to substantial error if the temporal sampling interval is too coarse. Techniques to mitigate these errors typically make use of advection-correction procedures (space-to-time conversions) in which the analyzed radial velocity or reflectivity field is idealized as a pattern of unchanging form that translates horizontally at constant speed. The present study is concerned with an advection-correction procedure for the reflectivity field in which the pattern-advection components vary spatially. The analysis is phrased as a variational problem in which errors in the frozen-turbulence constraint are minimized subject to smoothness constraints. The Euler–Lagrange equations for this problem are derived and a solution is proposed in which the trajectories, pattern-advection fields, and reflectivity field are analyzed simultaneously using a combined analytical and numerical procedure. The potential for solution nonuniqueness is explored.
'Common courtesy' and the elimination of passive smoking. Results of the 1987 National Health Interview Survey (1990)

The tobacco industry recommends "common courtesy" as the solution to potential conflicts over smoking in public places and as an alternative to policies that restrict or ban smoking. Specifically, the industry suggests that nonsmokers "mention annoyances in a pleasant and friendly manner" and that smokers ask others, "Do you mind if I smoke?" We analyzed data for 22 000 adults who responded to the 1987 National Health Interview Survey of Cancer Epidemiology and Control to determine if common courtesy is being used in passive-smoking situations. Almost half (47%) of smokers said they light up inside public places without asking if others mind. When someone lights up a cigarette inside a public place, only 4% of nonsmokers ask the person not to smoke despite the fact that most nonsmokers consider secondhand smoke harmful and annoying. We compared these data with similar data collected by the Roper Organization in the 1970s and found that smokers today are less likely to smoke inside public places. However, nonsmokers' actions in response to secondhand smoke have changed very little. These findings show that the common courtesy approach endorsed by the tobacco industry is unlikely, by itself, to eliminate exposure to environmental tobacco smoke. Though no one would oppose the use of common courtesy, we conclude that legislative or administrative mechanisms are the only effective strategies to eliminate passive smoking.

BF<sub>3</sub>·OEt<sub>2</sub>-Mediated Highly Regioselective S<sub>N</sub>2-Type Ring-Opening of <i>N</i>-Activated Aziridines and <i>N</i>-Activated Azetidines by Tetraalkylammonium Halides (2009)

A highly regioselective Lewis acid-mediated S(N)2-type ring-opening of N-sulfonylaziridines and azetidines with tetraalkylammonium halides in CH(2)Cl(2) solution to afford 1,2- and 1,3-haloamines in excellent yields is described. An easy diastereoselective route toward substituted chiral N-tosylaziridines has been developed. The mechanism of ring-opening via S(N)2 pathway has been confirmed by the formation of chiral haloamines with excellent er and dr. Chloroamines obtained from 2,3-disubstituted aziridines were converted to the chiral N-tosylamines via radical dehalogenation.
Adsorption of Polyacrylamide on Smectite, Illite, and Kaolinite (2006)

Interactions between polyacrylamides (PAMs) and clay minerals are the primary reactions in most applications of the water‐soluble polymers. Our main objectives were to study (i) the effects of charge of PAM on the flocculation/dispersion of clay suspensions and on the adsorption of the polymers on clays, and (ii) the surface properties of PAM‐clay complexes. Three PAMs—an anionic PAM 836A, a nonionic PAM 903N, and a cationic PAM 494C—were used to react with three common clay minerals—smectite, kaolinite, and illite. In the polymer concentration range tested (0–1.2 g L −1 ), the anionic PAM 836A increased the dispersion of the clay suspensions but the cationic PAM 494C promoted the flocculation. The strong flocculation function of cationic PAM 494C made trapped clay particles inaccessible for adsorption despite its highest affinity for clay surfaces. The adsorption of the polymers was irreversible. Nonionic PAM 903N and cationic PAM 494C intercalated smectite but anionic PAM 836A did not. The adsorbed polymer moderately altered the charge properties: the cation exchange capacity (CEC) and the abilities to remove heavy metal Cu and Cr had the following order: anionic PAM 836A‐clay > nonionic PAM 903N‐clay ≈ clay > cationic PAM 494C‐clay. The PAM‐clay complexes did not show distinct adsorption for hydrophobic chlorophenols, indicating that the adsorbed polymers did not increase the hydrophobicity of the clay surfaces.
A CORRELATION FOR VISCOSITY AND SOLVENT MASS FRACTION OF BITUMEN-DILUENT MIXTURES (2000)

ABSTRACT A simple equation is presented for predicting the kinematic viscosity of bitumens and heavy oils mixed with diluents. The correlation has been shown to provide accurate viscosity estimates of these mixtures for a wide range of data and requires only the knowledge of the pure bitumen and pure solvent viscosities at any given temperature. The correlation makes use of a viscosity reduction parameter which reduces error significantly when compared to similar equations presented by Chirinos et al. (1983), and Cragoe (1933). For a total of 89 data points, excluding the pure bitumens and diluents values, the correlation yielded an overall average absolute deviation of about 14 percent. The same equation was applied to predict the mass fraction of diluent required to reduce bitumen viscosity to pumping viscosity. Predicted values matched experimental values very well, with an overall average absolute deviation of about 6 percent.
A Direct-Conversion CMOS RF Receiver Reconfigurable From 2 to 6 GHz (2010)

A CMOS direct-conversion receiver with only one signal path is reconfigurable from 2 to 6 GHz in the RF band and from 3.6 to 54 MHz in the channel bandwidth. By employing a voltage feedback in a common-gate low-noise amplifier (LNA), the input matching of the LNA can be reconfigured for each RF band by simply changing the resonant frequency of the load network. The frequency characteristics of the active-RC channel selection filter with an R-2R ladder is automatically tuned by a one-shot tuning circuit. Implemented in 0.18- μm RF CMOS technology, the whole receive path shows 4.6-5.6-dB noise figure while consuming 65-75 mA from a 1.8-V supply depending on the mode of operation.
Get Smart (2010)

Energy generation, consumption, and conservation are at the root of many of the most pressing issues facing society today. It is the thesis of this article that the achievement of energy conservation and, hence global emission reductions can be significantly accelerated by integrating smart, energy-efficient appliances into a "smart" electricity grid - the so called "smart grid". And a key feature of this smart grid is demand response.
Identification of protease isozymes after analytical isoelectric focusing using fluorogenic substrates impregnated into cellulose membranes. (1984)

A technique to characterize active isozymes of proteases is described. After isoelectric focusing in an ultrathin gel, a cellulose diacetate or hydrate membrane previously impregnated with media containing a fluorogenic substrate is applied to the surface of the gel. Low-molecular-weight peptide inhibitors can also be added to the membrane to enhance specificity. The technique shows excellent reproducibility, specificity, and sensitivity, and has promise for the study of isozymes of proteases in tissues and body fluids in normal and pathological states.
Curve Decomposition for Large Deflection Analysis of Fixed-Guided Beams With Application to Statically Balanced Compliant Mechanisms (2012)

Statically balanced compliant mechanisms require no holding force throughout their range of motion while maintaining the advantages of compliant mechanisms. In this paper, a postbuckled fixed-guided beam is proposed to provide the negative stiffness to balance the positive stiffness of a compliant mechanism. To that end, a curve decomposition modeling method is presented to simplify the large deflection analysis. The modeling method facilitates parametric design insight and elucidates key points on the force–deflection curve. Experimental results validate the analysis. Furthermore, static balancing with fixed-guided beams is demonstrated for a rectilinear proof-of-concept prototype.
Reduced IL-6 Levels among Individuals in Hudson County, New Jersey, an Area Contaminated with Chromium (1996)

Hudson County, New Jersey, was a major center for the processing of chromium ore. After processing, some of the ore residue that contained low concentrations of chromium became distributed in population centers throughout the county. There now exists concern in the county about possible health effects from chromium exposure. Our previous research suggested that immune-function assays would make useful biomarkers for chromate exposure in humans. Blood samples were drawn from 46 individuals who lived and/or worked in Hudson County and from 47 controls. Only one of the immune-associated assays performed on these samples showed any statistically significant differences between the Hudson County and control groups. The mean level of IL-6 produced by pokeweed mitogen-stimulated mononuclear cells isolated from the Hudson County group was 64% of the control value--a highly significant decrease (p<.001). There was also a significant correlation between the proliferative responses of the mononuclear cells to pokeweed mitogen and the levels of IL-6 produced by these cells. No differences were detected in the IL-6 responses that resulted from age, gender, or smoking status. The reliability of the IL-6 assay was found to be 90%. To our knowledge, there have been no reports, until now, that describe reduced production of any cytokine in individuals who are exposed to chromate.
Handling Ontology Change: Survey and Proposal for a Future Research Direction (2005)

One of the crucial tasks towards the realization of the vision of the Semantic Web is the efficient encoding of human knowledge in ontologies. The proper maintenance of these, usually large, structures and, in particular, the adaptation of ontologies to new knowledge (ontology change) is one of the most challenging problems in the Semantic Web research. Due to the uncontrolled and decentralized nature of the Semantic Web, ontology change is a complicated and multifaceted task; this has led to the emergence of several different, but closely related, research areas that deal with the problem. In this report, we attempt to draw a clear line between these research areas, by underlying their relations, interactions and overlaps. Our work uncovers a certain gap in the current research and proposes a supplementary research direction, based on belief revision. We argue that our approach uncovers an interesting new dimension to the problem that is likely to find important applications in the future.

Wine clarification and protein removal by bentonite (1963)

Abstract Addition of bentonite to young wines is a normal clarifying procedure widely used in Australian winemaking. Flocculation is usually rapid but poor flocculation has been observed, particularly in wines which have been passed through a sodium cation‐exchange resin to prevent deposition of potassium bitartrate. The behaviour of bentonite in wines treated by cation‐exchange resin was examined in detail. Dispersion was associated with a high proportion of sodium and a low proportion of calcium and magnesium, in conjunction with the presence of a dispersing compound of high molecular weight. Results were consistent with the dispersing agent being a negatively‐charged carbohydrate. Such a compound was shown to be present by electro‐phoresis. Flocculation in wines treated by a cation‐exchange resin will then depend on the relative amounts of this carbohydrate which disperses bentonite, and protein which flocculates it. Some commercial bentonites flocculate much more easily in low concentrations of divalent cation than the natural sodium bentonites, but these were found to remove protein far less effectively. In practice, bentonite fining should be carried out either before cation‐exchange treatment, or a protein such as gelatin may be added to the treated wine to ensure flocculation.
Softness measurements for open-cell foam materials and human soft tissue (2006)

In this paper, methods of measuring the softness of open-cell polyurethane foams in terms of their Young's modulus using indentation methods are investigated and shown to be in agreement with values determined by normal compression tests. The comparison involved the use of a formula relating Young's modulus for elastomers to the axial indentation forces on a cylindrical probe. This had been developed for cartilage and verified for other biological tissues and could not automatically be assumed to be valid for an open-cell structure. An indentation method was then used to characterize the soft tissues of the female human body, averaging over several locations on the body and for several volunteers. It is concluded that the mechanical characteristics of foams can be measured in a repeatable manner by the indentation method and that appropriate foams can therefore be selected for use in a soft mannequin which will then accurately simulate the texture and mechanical behaviour of human soft tissue.
The synergistic effect of inert oxide and metal fluoride dual coatings on advanced cathode materials for lithium ion battery applications (2016)

The effect of Al2O3/LiF dual coatings on the electrochemical performance of over-lithiated layered oxide (OLO) has been investigated. A uniform coating of Al2O3 and LiF is obtained on the surface of the layered pristine material. The OLO with a dual Al2O3/LiF coating with a ratio of 1 : 1.5 exhibits excellent electrochemical performance. An initial discharge capacity of 265.66 mA h g(-1) is obtained at a C-rate of 0.1C. This capacity is approximately 15 mA h g(-1) higher than that of pristine OLO. The capacity retention (92.8% at the 50th cycle) is also comparable to that of pristine OLO (91.4% at the 50th cycle). Coating the cathode with a dual layer comprising Al2O3 and LiF leads to improved charging and discharging kinetics, and prevents direct contact between the cathode and the electrolyte.
A succinct review of botulinum toxin in dermatology; update of cosmetic and noncosmetic use (2011)

Botulinum toxin A has a wide variety of clinical applications in medical and dermatologic sciences. Nowadays, researchers introduce some other indications for botulinum toxin in cosmetic and especially noncosmetic aspects of dermatology such as medical rhinoplasty, hypertrophic scar, chemical brow lift, supraciliary wrinkles, pompholix, eccrine angiomatosis, Hailey-Hailey, dermatochalasis, lichen simplex, nosthalgia parestetica, and granulosis rubra nasi. In this general overview of the use of botulinum toxin in dermatology, an extensive literature search was carried out to updates of all dermatology-oriented experiments and clinical trials on the mentioned aspect of botulinum toxin.

Oregon Speedcode Universe (OSU) is a software development environment for design, implementation, and maintenance of large software systems. Designed to be highly visual, OSU combines traditional structured-analysis techniques found in most computer-aided software engineering tools with the advanced graphical user-interface management systems found on most contemporary workstations. The design and implementation of four minute features of OSU are described: (1) the combination of functional decomposition with object-oriented design; (2) alternate architectural views, e.g. call graph, uses graph, object graph, and graphical display of procedures; (3) program understanding tools for design and maintenance; and (4) merging the user-interface specification with design and coding specifications.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Genetic transformation of molybdenum-starved <i>Azotobacter vinelandii</i>: increased transformation frequency and recipient range (1985)

Azotobacter vinelandii Nif − mutants UW3, UW45, and UW91 that did not become competent for genetic transformation after growth in Fe-limited competence induction medium did become competent when Mo starvation also was imposed. Mo starvation of other Fe-limited competent strains increased their frequency of transformation. Mo starvation also increased the frequency of transformation of strain UW1 with heterologous DNA from Azotobacter, Rhizobium, and Beijerinckia. Mo starvation did not increase the competence of the encapsulated A. vinelandii strain ATCC 12837. The substitution of mannitol or sorbitol for glucose in the Fe-limited competence induction medium, however, increased strain 12837 transformation frequency over 200-fold.
