Title: Monitoring dynamics of single-cell gene expression over multiple cell cycles

Source: MOLECULAR SYSTEMS BIOLOGY: doi:10.1038/msb4100032 2005

Abstract: Recent progress in reconstructing gene regulatory networks has established a framework for a quantitative description of the dynamics of many important cellular processes. Such a description will require novel experimental techniques that enable the generation of time-series data for the governing regulatory proteins in a large number of individual living cells. Here, we utilize microfabrication to construct a Tesla microchemostat that permits single-cell fluorescence imaging of gene expression over many cellular generations. The device is used to capture and constrain asymmetrically dividing or motile cells within a trapping region and to deliver nutrients and regulate the cellular population within this region. We illustrate the operation of the microchemostat with Saccharomyces cerevisiae and explore the evolution of single-cell gene expression and cycle time as a function of generation. Our findings highlight the importance of novel assays for quantifying the dynamics of gene expression and cellular growth, and establish a methodology for exploring the effects of gene expression on long-term processes such as cellular aging.

Title: Beyond communication: research as communicating. Making user and audience studies matter - paper 2

Source: INFORMATION RESEARCH-AN INTERNATIONAL ELECTRONIC JOURNAL, 12 (1): Art. No. 287 OCT 2006

Abstract: Introduction. This is the written version of the keynote address (Making user studies matter: Thank you Mister Feynman and Monsieur Foucault) delivered by senior author Dervin. The paper is linked to the Invited Paper in this issue and like that paper, reports on a project involving a dialogue between researchers and practitioners in library and information science, human computer interaction and communication focusing on gaps in our understandings of users and audiences as well as in our efforts to collaborate with each other to conduct and apply research to the design and implementation of information, library, communication, and media systems.
Argument. Our main conclusion in Paper 1 was that the traditional modes used for communication in social science research are not doing the job for user and audience studies. We set out five propositions relating to this conclusion: (1) the traditional modes of communicating in the research enterprise are not working; (2) Do the social sciences matter? Some serious and fundamental attacks; (3) a call to focus on the special problematics of the social sciences: agency, structure, power and the good; (4) eschewing scientific recipes and scholarly creeds and bringing back the joys of adventuring and muddling; (5) the paradox of communicating freedom is another word for nothing left to lose.
Conclusion. We argue for shared dialogue in communicating across the three fields studied here: this will introduce uncertainty, but, rather than relying upon 'authority', the individual will be encouraged through the exploration of that uncertainty, to make their own sense of the offerings of others.

Title: Vortex shedding in flows of dilute polymer solutions

Source: JOURNAL OF NON-NEWTONIAN FLUID MECHANICS, 139 (1-2): 54-67 NOV 15 2006

Abstract: Experiments on vortex shedding from a cylinder placed in uniform flows of low concentration polymer solutions are reported for Reynolds numbers from 50 to 150. The fluids used were aqueous solutions of polyethylene oxide (PEO) and Weissenberg numbers were O(10(-1)). It is shown that even small amounts of PEO have a significant stabilizing effect on the von Karman instability which is in turn destabilized by shear-thinning at higher concentrations. The presence of PEO is also observed to reduce the saturated vortex shedding frequency and cause a redistribution of velocity fluctuations in the attached shear layers. At higher concentrations further changes in the velocity fluctuations are noted in the wake. Downstream of the cylinder an overshoot in the time-average streamwise velocity is measured for the polymer solutions and an analogy is drawn to the negative wake behind a sphere falling in a viscoelastic fluid.

Title: Einstein's "Zur elektrodynamik ..." (1905) revisited, with some consequences

Source: FOUNDATIONS OF PHYSICS, 36 (7): 955-1011 JUL 2006

Abstract: Einstein, in his "Zur Elektrodynamik bewegter Korper", gave a physical (operational) meaning to "time" of a remote event in describing "motion" by introducing the concept of "synchronous stationary clocks located at different places". But with regard to "place" in describing motion, he assumed without analysis the concept of a system of co-ordinates.
In the present paper, we propose a way of giving physical (operational) meaning to the concepts of "place" and "co-ordinate system", and show how the observer can define both the place and time of a remote event. Following Einstein, we consider another system "in uniform motion of translation relatively to the former". Without assuming "the properties of homogeneity which we attribute to space and time", we show that the definitions of space and time in the two systems are linearly related. We deduce some novel consequences of our approach regarding faster-than-light observers and particles, "one-way" and "two-way" velocities of light, symmetry, the "group property" of inertial reference frames, length contraction and time dilatation, and the "twin paradox". Finally, we point out a flaw in Einstein's argument in the "Electrodynamical Part" of his paper and show that the Lorentz force formula and Einstein's formula for transformation of field quantities are mutually consistent. We show that for faster-than-light bodies, a simple modification of Planck's formula for mass suffices. (Except for the reference to Planck's formula, we restrict ourselves to Physics of 1905.)

Title: Fabrication of coaxial metal nanocables using a self-assembled peptide nanotube scaffold

Source: NANO LETTERS, 6 (8): 1594-1597 AUG 9 2006

Abstract: The design and fabrication of complex nanostructures with specific geometry and composition is one of the main challenges of nanotechnology. Here we demonstrate the devise of metal-insulator-metal, trilayered, coaxial nanocables. Such coaxial geometry may give rise to useful and unique electromagnetic properties. We have fabricated these nanostructures using a scaffold of self-assembled peptide nanotubes. Gold nanoparticles were bound to the surface of peptide nanotubes via a common molecular recognition element that was included in various linker peptides. This enabled us to promote site-specific metal reduction and to create the coaxial nanostructure. Using electron microscopy, H-1 NMR spectra, and energy-dispersive X-ray analysis, we monitored the different steps within the process, gaining further understanding of its mechanism.

Title: Decoding mental states from brain activity in humans

Source: NATURE REVIEWS NEUROSCIENCE, 7 (7): 523-534 JUL 2006

Abstract: Recent advances in human neuroimaging have shown that it is possible to accurately decode a person's conscious experience based only on non-invasive measurements of their brain activity. Such 'brain reading' has mostly been studied in the domain of visual perception, where it helps reveal the way in which individual experiences are encoded in the human brain. The same approach can also be extended to other types of mental state, such as covert attitudes and lie detection. Such applications raise important ethical issues concerning the privacy of personal thought.

Title: Designing triple resonance Tesla transformers of arbitrary modal frequency ratio

Source: REVIEW OF SCIENTIFIC INSTRUMENTS, 77 (3): Art. No. 033301 Part 1 MAR 2006

Abstract: The purpose of this article is to disclose an automated method to design and investigate multimegavolt triple resonance Tesla transformers. The pulse transformer's "frequency equation" is presented for the first time. The frequency equation derivation properly models all the inductors, with their self-capacitances, which have yet to be treated in an orthodox manner. The analysis gives new insight into the transformer by showing the relationship between the roots of the frequency equation and the transformer's modal frequencies. The roots are shown to be subject to manipulation, and so the modal frequencies are controllable. The method efficiently extracts solutions (transformer circuits) from the frequency equation constrained to oscillate at an arbitrary and general modal frequency ratio (to include noninteger). A ratio of the present general interest is 1:2:3. This particular ratio forces the maxima of the three coexisting modal oscillations to align, and their amplitudes sum to produce a local maximum, at a specific time. The same alignment phenomenon occurs with the dual resonance transformer with a modal ratio of 1:2. A pulse transformer is designed as a demonstration. The energy in each of the three oscillations is examined at the moment of peak voltage in the demonstration transformer to show the investigative power of the new equations. This generalized tool will prove useful in the campaign to analytically locate global maximums from the triple resonance transformer's governing amplitude equation for output voltage.

Title: Analytical expression for the output voltage of the triple resonance Tesla transformer

Source: REVIEW OF SCIENTIFIC INSTRUMENTS, 76 (10): Art. No. 104702 OCT 2005

Abstract: An analytical expression for the time-dependent output voltage of the triple resonance Tesla transformer is presented. Presently there does not exist any closed-form solution for the output voltage, and the investigators must use circuit simulators to examine the transformer's performance. Such simulators are satisfactory in many regards, but they cannot furnish physical insight into the triple resonance device. A governing equation provides this needed insight and opens the way for obtaining optimal high-performance transformers. The present analysis treats the transformer as three oscillatory LC tank circuits feeding a load capacitance. The circuit is assumed to have a very high Q, which is a fundamental design practice for these pulsed power supplies. The formula is exercised using a known triple resonance circuit, and the results closely agree with the analysis of an industry standard circuit simulator. (c) 2005 American Institute of Physics.

Title: Improvements in fixed-valve micropump performance through shape optimization of valves

Source: JOURNAL OF FLUIDS ENGINEERING-TRANSACTIONS OF THE ASME, 127 (2): 339-346 MAR 2005

Abstract: The fixed-geometry valve micropump is a seemingly simple device in which the interaction between mechanical, electrical, and fluidic components produces a maximum output near resonance. This type of pump offers advantages such as scalability, durability, and ease of fabrication in a variety of materials. Our past work focused on the development of a linear dynamic model for pump design based on maximizing resonance, while little has been done to improve valve shape. Here we present a method for optimizing valve shape using two-dimensional computational fluid dynamics in conjunction with an optimization procedure. A Tesla-type valve was optimized using a set of six independent, non-dimensional geometric design variables. The result was a 25% higher ratio of reverse to forward flow resistance (diodicity) averaged over the Reynolds number range 0 < Re <= 2000 compared to calculated values for an empirically designed, commonly used Tesla-type valve shape. The optimized shape was realized with no increase in forward flow resistance. A linear dynamic model, modified to include a number of effects that limit pump performance such as cavitation, was used to design pumps based on the new valve. Prototype plastic pumps were fabricated and tested. Steady-flow tests verified the predicted improvement in diodicity. More importantly, the modest increase in diodicity resulted in measured block-load pressure and no-load flow three times higher compared to an identical pump with non-optimized valves. The large performance increase observed demonstrated the importance of valve shape optimization in the overall design process for fixed-valve micropumps.

Title: Micropumps - past, progress and future prospects

Abstract: If a high and on-going research dynamics is taken as a rejuvenating factor rnicrofluidics can still be regarded as a truly young discipline, although some microfluidic devices definitely can not be considered as "youngsters" any more. In a time of 30 years of ISFETOLOGY it may be worth to take a look at these devices in order to examine, whether they had-and still have-the potential to stimulate the imagination and creativity of researchers in a similar way as the Ion Sensitive Fieldeffect Transistor did since its invention in 1970. The area of micropumps is definitely one of those "long runners". Starting in the mid 1970s a steadily growing and astonishing diversity of micropump principles, technical concepts and applications has emerged in this area. Until today MEMS science is delivering a constant flow of novel modelling approaches, microstructured materials, actuation principles, fabrication technologies and applications, that are readily taken and transferred into micropump research. Among the potential applications especially the combination of biochemical sensing and microfluidics has provided a substantial stimulus for micropump research and development in the past and will do so in the future.

Title: A resonant, self-pumped, circulating thermoacoustic heat exchanger

Source: JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA, 116 (5): 2923-2938 NOV 2004

Abstract: An asymmetrical constriction in a pipe functions as an imperfect gas diode for acoustic oscillations in the pipe. One or more gas diodes in a loop of pipe create substantial mean flow, approximately proportional to the amplitude of the oscillations. Measurements of wave shape, time-averaged pressure distribution, mass flow, and acoustic power dissipation are presented for a two-diode loop. Analysis of the phenomena is complicated because both the mean flow and the acoustic flow are turbulent and each affects the other significantly. The quasi-steady approximation yields results in rough agreement with the measurements. Acoustically driven heat-transfer loops based on these phenomena may provide useful heat transfer external to thermoacoustic and Stirling engines and refrigerators.

Title: Pinhole formation in capacitively coupled external electrode fluorescent lamps

Source: JOURNAL OF PHYSICS D-APPLIED PHYSICS, 37 (20): 2863-2867 OCT 21 2004

Abstract: Application of power higher than the optimum operation value to an external electrode fluorescent lamp (EEFL) leads to the formation of pinholes, which subsequently leads to lamp failure. Small holes, called pinholes, are formed through the external electrode and the glass tube when a high voltage with a high power is applied. The phenomenon of pinhole formation has been investigated, including the conditions under which they occur and the characteristics such as size and location on the electrode. Pinhole formation has been analysed and shown to be the insulation layer breakdown of glass in the dielectric barrier discharge of capacitively coupled EEFLs.

Title: Suppression method of grating lobe by pulse power transmission from an array antenna

Source: ELECTRONICS AND COMMUNICATIONS IN JAPAN PART I-COMMUNICATIONS, 88 (2): 1-10 2005

Abstract: A new method is proposed for suppressing the grating lobe (GL) by pulse power transmission from an array antenna. GL suppression relies on the fact that the maximum electric field value is not synthesized by the waves from the array antenna at the undesired points even if the maximum electric field is attained at the desired receiving point, because the pulses emerging from different antenna elements do not overlap. Two computer simulations are carried out to confirm this suppression effect. In the simulation using a two-element array antenna with all element spacing exceeding one wavelength, the GL suppression effect is confirmed with a pulsed wave even though the GL is generated with a continuous wave. In pulsed power transmission simulation with many elements, the GL suppression effect is enhanced with an increasing number of elements. It is also found that the effect increases as the pulse width becomes smaller. (C) 2004 Wiley Periodicals, Inc.

Source: APPLIED PHYSICS LETTERS, 85 (19): 4508-4510 NOV 8 2004

Abstract: Low-temperature measurements show that an asymmetric mesoscopic junction patterned in a two-dimensional electron gas can exhibit tunable rectification, including sign reversal. Strikingly, we observe that the amplitude and sign of the effect are governed by the conductances of the channels and that rectification is reversed without reversing the asymmetry of the device. Based on the temperature dependence of the rectified voltage, we show that the effect is ballistic and exhibits unexpected features with respect to predictions of available models.

Title: A microfluidic rectifier: Anisotropic flow resistance at low Reynolds numbers

Source: PHYSICAL REVIEW LETTERS, 92 (9): Art. No. 094501 MAR 5 2004

Abstract: It is one of the basic concepts of Newtonian fluid dynamics that at low Reynolds number (Re) the Navier-Stokes equation is linear and flows are reversible. In microfluidic devices, where Re is essentially always low, this implies that flow resistance in microchannels is isotropic. Here we present a microfluidic rectifier: a microscopic channel of a special shape whose flow resistance is strongly anisotropic, differing by up to a factor of 2 for opposite flow directions. Its nonlinear operation at arbitrary small Re is due to non-Newtonian elastic properties of the working fluid, which is a 0.01% aqueous solution of a high molecular weight polymer. The rectifier works as a dynamic valve and may find applications in microfluidic pumps and other integrated devices.

Abstract: This review article extends previous scientific definitions of the biofield (endogenous energy fields of the body) to include nonclassical and quantum energy fields. The biofield is defined further in terms of its functional property to act as a resonance target for external forms of energy used as treatment modalities in energy medicine. The functional role of the biofield in the body's innate self-healing mechanisms is hypothesized, based on the concept of bioinformation which, mediated by consciousness., functions globally at the quantum level to supply coherence, phase, spin, and pattern information to regulate and heal all physiologic processes. This model is used to explain a wide variety of anomalies reported in the scientific literature, which can not be explained by traditional biophysics and bioelectromagnetics.

Source: JOURNAL OF PHYSICS D-APPLIED PHYSICS, 36 (20): 2526-2530 OCT 21 2003

Abstract: The external electrode fluorescent lamp (EEFL) is operated in a high frequency mode because the lamp lighting is basically a dielectric barrier discharge. The self-discharge synchronization is defined by synchronizing the self-discharge time of the dielectric wall charge with the voltage rising and falling time. It is shown that for the self-discharge synchronization a high brightness is obtained in the multi-lamps backlight connected in parallel with the EEFLs operated with square waves from a switching inverter. The frequency for self-discharge synchronizing is also shown to increase as the driving voltage increases.

Title: Low-order modeling of resonance for fixed-valve micropumps based on first principles

Source: JOURNAL OF MICROELECTROMECHANICAL SYSTEMS, 12 (3): 325-334 JUN 2003

Abstract: Micropumps that utilize fixed-valves, i.e., valves having no moving parts, are relatively easy to fabricate and inherently reliable due to their simplicity. Since fixed-valves do not close, pumps based on them need to operate in a well-designed resonant mode in order to attain flow rates and pressures comparable with other designs. However, no methodology currently exists to efficiently investigate all the design parameters including valve size to achieve optimal resonant response. A methodology that addresses this problem is 1) the determination of optimal parameters including valve size with a low-order linear model capable of nonempirical prediction of resonant behavior, and 2) the independent determination of the best valve shape for maximal valve action over a target Reynolds number range. This study addresses the first of these two steps. The hypothesis of this study is that the resonant behavior of a fixed-valve micropump can be accurately predicted from first principles, i.e., with knowledge only of geometric parameters and physical constants. We utilized a new low-order model that treats the valves as straight rectangular channels, for which the unsteady solution to the Navier-Stokes equations is exact and with which the problem was linearized. Agreement with experiment using pump-like devices with valves replaced by straight channels was found to be excellent, thereby demonstrating the efficacy of the model for describing all aspects of the pump except actual valves. Agreement with experiment using pumps with Tesla-type valves was within 20 percent. With such accuracy and without the need for empirical data, the model makes possible reliable, efficient investigation and optimization of over 30 geometric and material parameters.

Title: Spin asymmetries in deep-inelastic electron-nucleon scattering - Selected HERMES results

Source: PROGRESS IN PARTICLE AND NUCLEAR PHYSICS, VOL 49 NO 2, 49 (2): 245-324 2002

Book series title: PROGRESS IN PARTICLE AND NUCLEAR PHYSICS

Abstract: The HERMES collaboration has collected many millions of deep-inelastic lepton-nucleon scattering events during the years 1995-2000, i.e. the first phase of the experiment. Longitudinally polarised electron or positron beams in the HERA electron storage ring were incident on longitudinally polarised internal atomic gas targets as well as several nuclear gas targets. The primary goal of the HERMES experiment is the study of the spin structure of the nucleon. High precision measurements of double-spin asymmetries in inclusive and semi-inclusive scattering from undiluted polarised atomic hydrogen, deuterium and He-3 gas targets are presented. These data represent the world's most precise experimental determination to date of the separate contributions of the spin of up, down and strange quarks to the spin of the nucleon, and the first direct indication of a positive gluon polarisation. The observation of single-spin asymmetries in the azimuthal distributions of hadrons in semi-inclusive deep-inelastic scattering from longitudinally polarised targets is also presented. These single-spin asymmetries can be related to transversity, the only unmeasured of the three leading twist parton distribution functions. Moreover, first measurements of single-spin asymmetries in hard exclusive production of real photons and of pions are reported. Such data can be interpreted in the framework of generalised parton distributions, which is also used when discussing new data on hard exclusive electro-production of the vector mesons rho, omega and phi. Finally some results from measurement of longitudinal spin transfer in electro-production of A hyperons, and of transverse Lambda polarisation in quasi-real photo-production are discussed.

Abstract: Recent experimental results from the HERMES collaboration at DESY and the SMC collaboration at CERN suggest that it may be possible to access nucleon transversity distributions through the measurement of transverse single spin asymmetries in semi-inclusive hard scattering processes. In this paper we review the prospects of studying transversity distributions in polarized, proton proton collsions at RHIC. To unfold transversity distributions from the observable single spin asymmetries the knowledge of novel fragmentation functions is necessary. We include a discussion of the measurement of the relevant fragmentation functions in e(+)e(-) annihilation at the KEK b-factory.

Abstract: The lives of Michael Faraday and Charles Babbage, with their common birth year of 1791, were closely linked by their personal friendship, scientific interests and wide circle of friends. Our 'electrical civilization' is synonymous with Faraday and our 'computer age' has much praise for Babbage. However, little has been written about their common history; this article is a belated contribution to their bicentenary.

Title: Automatic termination of Radiofrequency energy upon catheter dislocation

Source: BIOMEDIZINISCHE TECHNIK, 47 (7-8): 186-190 JUL-AUG 2002

Abstract: Since 1987 radiofrequency (RF) catheter ablation has proven to be an effective treatment for many cardiac arrhythmias. However, catheter dislocation during RF delivery may result in an unintentional heating of healthy non-arrhythmogenic tissue. Therefore, a device was developed (15 cm x 9 cm x 3 cm) consisting of a microprocessor, powered by a 9 V battery and to be connected between the indifferent cable of the RF generator and the patient's back electrode that continuously reads the electrode position information using a 3 dimensional electrode, visualization system (LocaLisa). A red light indicates a sudden change in electrode position and an electronic switch is activated by the software to interrupt the connection between the indifferent electrode and the RF generator resulting in a high impedance shutdown and termination of RF energy delivery. Four different sensitivity settings (10 is most and 100 is least sensitive) can be selected and were tested in an in vitro tank setup during electrode dragging speeds of 0.5 to 20 cm/sec. For the sensitivity levels 10, 20, 50 and 100, an immediate termination of RF (Atakr II, Medtronic, 25 W) was demonstrated for an electrode dragging speed of greater or equal than 1, 2, 5 and 10 cm/sec, respectively. We conclude that the developed device may improve safety during ablation procedures of cardiac arrhythmias.

Title: Development of optical computerized tomography in capacitively coupled plasmas and inductively coupled plasmas for plasma etching

Source: APPLIED SURFACE SCIENCE, 192 (1-4): 88-114 MAY 30 2002

Abstract: In this paper we review the results of optical emission spectroscopy (OES) in diagnostics of radio frequency (rf) discharges. The status of OES diagnostics of rf plasmas used primarily for plasma etching has been reviewed for the past 15 years. The results obtained at Keio University have been reviewed in greater detail.
Time resolved and time-averaged computerized tomography (CT) of OES has been applied to obtain 2D and 3D profiles of emission for a large number of gases (Ar, H-2, SiH4, Cl-2, CF4, O-2, SF6) and gas mixtures. Application of OES-CT has become essential in understanding the sustaining mechanisms in capacitively coupled plasmas (CCPs) and in inductively coupled plasmas (ICPs) operating in rf. Those plasmas are produced in a wide range of frequencies, or combinations of frequencies and pulsed conditions. In addition, a wide range of geometries has been covered, providing an insight into spatial profiles of excitation (i.e. production of radicals) and therefore the uniformity of plasma etching. In our laboratory the technique was first applied to magnetrons.
In CCP spatially resolved emission profiles were obtained for complex geometries and furthermore the effects of high frequency, two frequencies and pulsed operation were studied. Control of dust particles could be implemented by the same technique. Absolute values as well as the time resolved data showed the importance of the double layers in front of the instantaneous anode in maintaining the rf discharges in electro-negative gases.
In ICP, CT was used to study the azimuthal anisotropy and the axial dependence of emission. Transition from capacitively to inductively coupled mode of operation could be proved directly by OES-CT profiles. Time resolved data for emission close to the coil showed two peaks with 45degrees phase difference, one of which was unexpected. In addition the effect of electro-negative gas and pulsing of the rf field were studied.
It has been concluded that OES supplemented by fast, detailed models may be used for efficient real time control of plasma etching devices of the next generation. (C) 2002 Elsevier Science B.V. All rights reserved.

Title: Reginald Aubrey Fessenden and the birth of wireless telephony

Source: IEEE ANTENNAS AND PROPAGATION MAGAZINE, 44 (2): 38-47 APR 2002

Abstract: The year 2000 was the 100th anniversary of the transmission of the first voice over radio. On December 23, 1900, Prof. Reginald Aubrey Fessenden (Figure 1) - after a number of unsuccessful tries - transmitted "words without wires" over a distance of 1600 m, between twin aerial systems employing 15 m masts, located on Cobb Island, Maryland. The quality of the received wireless-telephony transmission was reported to be perfectly intelligible, but the speech was accompanied by an extremely loud, disagreeable noise, due to the irregularity of the spark. Spark? Yes. Fessenden had not yet developed a method to generate continuous waves. The sender was a spark transmitter, operating at 10,000 sparks/second, with an asbestos-covered carbon microphone inserted in the antenna lead. In spite of the primitive apparatus used, the poor quality of the transmission, and the short distance, intelligible speech had been transmitted by electromagnetic waves for the first time in the history of wireless.
Who was Fessenden? The purpose of this paper is to touch upon his life's history, and to give some detail of his accomplishments. However, the paper begins with a brief account of the birth of radio, so that the reader can appreciate Fessenden's place in history.

Abstract: Recent experimental results from the HERMES collaboration at DESY and the SMC collaboration at CERN suggest that it may be possible to access nucleon transversity distributions through the measurement of transverse single spin asymmetries in semi-inclusive hard scattering processes. In this paper we review current and future experimental activities to measure transversity. We include a discussion of the measurement of the relevant fragmentation functions in e(+)e(-) annihilation.

Title: Multiple resonance networks

Source: IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS I-FUNDAMENTAL THEORY AND APPLICATIONS, 49 (2): 240-244 FEB 2002

Abstract: This brief shows how "multiple resonance networks" of any order and with many possible structures can be systematically designed using standard lossless impedance synthesis techniques. These networks are composed of linear lumped or distributed capacitors, inductors, and transformers, with a switch separating one of the capacitors from the remaining circuit. They have the property of transferring completely the energy initially stored in the capacitor insulated by the switch, to another, much smaller, capacitor in the circuit, through a linear transient when the switch is closed. These circuits rind applications In the production of very high voltages for pulsed power systems.

Title: Polymer-composite ball lightning

Source: PHILOSOPHICAL TRANSACTIONS OF THE ROYAL SOCIETY OF LONDON SERIES A-MATHEMATICAL PHYSICAL AND ENGINEERING SCIENCES, 360 (1790): 37-60 JAN 15 2002

Abstract: Investigations into the state of ball lightning (BL) have been made, and both theory and experiments, related to so-called 'polymer-composite' ball lightning, are presented. The properties of such a polymeric BL have been described and are that of a long-lived object capable of storing high energy. Results of experiments, starting with polymeric components in erosive gas discharge experiments, are described and discussed. The model of BL as a highly charged polymer-dielectric structure is described. According to this model BL appears as the result of the aggregation of natural polymers, such as lignin and cellulose, soot, polymeric silica and other natural dust particles. Its ability to glow is explained by the appearance over its perimeter of gas discharges near the highly charged BL surface, and electrical breakdown of some regions on the surface, consisting of polymerized and aggregated threads.

Title: Effect of low magnetic field on dairy cows

Source: TIERARZTLICHE UMSCHAU, 56 (7): 364-369 JUL 2001

Abstract: The purpose of this study was to determine the effect of direct and indirect exposure of the low magnetic field on dairy cows. 28 Holstein cows were used in the fir;st trial, they were assigned to four treatment groups. Cows were exposed to a magnetic field with a magnetic induction of 21.9 muT to 42.1 muT (group 1); 19,4 muT to 37,7 muT (group 2); 12,4 muT to 23,6 muT (group 3). The control group was in an environment with a zero-magnetic field.: The aver-uge dairy lowest milk yield was in the first and second groups (24,52 und 24,37 kg) during the whole 12-week trial period and the highest in the third group (26,67 kg). The differences were significant A negative impact on behaviour has not been proven. We used 25 Holstein cows divided to trial and control groups in the second trial. The cows of a treatment group were exposed to a low magnetic field with a magnetic induction ranging from 42.1 muT (head) to 21.9 muT (breech) during the 196th to I 258th day of gestation. Milk production of trial cows showed a lower trend as soon as in rite second month. A 513-kg significant difference (P <0.05) between control and treatment groups for the 305 d lactation (6910 kg vs. 7423 kg) was found. Iii the trial group, both the open days period of 24.6 days and calving interval of 24.8 days were shorter than in control cows. Based on this experiment it is concluded that a magnetic field with a magnetic induction of 19,4 muT to 42,1 muT effect can decrease milk: yield. The results did not show a negative effect of a magnetic field on growth behaviour and reproduction.

Title: Numerical and experimental studies of flat-walled diffuser elements for valve-less micropumps

Source: SENSORS AND ACTUATORS A-PHYSICAL, 84 (1-2): 165-175 AUG 1 2000

Abstract: An investigation of flat-walled diffuser elements for valve-less micropumps is presented. The diffuser element is a small angle flow channel with a rounded inlet and a preferably sharp outlet. The diverging-wall direction is the positive flow direction. The flow-directing capability under steady flow conditions was determined experimentally for several different diffuser elements. The flow-pressure characteristic was studied in detail for one of them. The result is compared with previously published results on pump performance. Numerical simulations were done using the Computational Fluid Dynamics program ANSYS/Flotran. The simulations show the flow-directing capability of the diffuser elements and predict the flow-pressure characteristics well for Reynolds numbers below 300-400. For higher Reynolds numbers, the simulations show the flow-directing capability, but there is a larger discrepancy between simulations and measurements. Simulations were also done for a nozzle element, a wide-angle flow channel with sharp inlet and outlets used in the micropump with dynamic passive-valves. A nozzle element has the converging-wall direction as positive flow direction. The simulations show differences in the flow patterns for diffuser elements and nozzle elements that explain the opposite positive flow directions. The diffuser element has an ordered flow and takes advantage of the pressure recovery in the diverging-wall direction. The nozzle element has gross flow separation in the diverging-wall direction and there is a "vena-contracta" effect instead of pressure recovery. The effective cross-sectional area is smaller in the diverging-wall direction than in the converging-wall direction. (C) 2000 Elsevier Science B.V. All rights reserved.

Title: Ring discharge plasma - optical emission spectroscopy in the assay of environmental mercury

Source: OPTICA APPLICATA, 29 (4): 487-514 1999

Abstract: Mercury is known as an element of significant toxicity, which may cause well-characterized health hazards in animals and men. For the first time the problem came into Light in the 1950s in Minamata, Japan. Since then the determination of mercury at ultratrace levels in environmental bodies has attained considerable importance. Consequently, several high sensitive mercury-analytical methods have been developed. In this work, the possibility of mercury assay at ultratrace levels in the environment using ring discharge plasma-optical emission spectroscopy (RDE - OES) is shown. Using this method the mercury content in different bodies in the Baltic Sea Area has been determined. Some data on mercury content and balance in serveral environmental bodies are also given.
