Interpretation value of diffractions and sub-specular reflections – applications on the Zhao Dong field (2017)

We provide an overview of integrated pre-stack depth migration and diffraction imaging for the Zhao Dong field, Bohai Bay, China. This field is highly compartmentalized by complex faulting and further characterized by channel systems, fractures and volcanic features. The objective of the diffraction imaging is to better define these small-scale features. Tools to facilitate interpretation include displays with pre-stack depth migration and diffraction images overlain in different colour scales, as well as a weighted blending of them into a single volume. An important concept is that of the sub-specular reflection, which is obtained alongside the pure diffraction image by applying ultra-weak specularity tapers. Tuning properties of elementary diffractor images together with sub-specular reflectors provide a decisive uplift of diffraction imaging for the interpreter.
A ONE-DIMENSIONAL TWO-PHASE FLOW MODEL AND EXPERIMENTAL VALIDATION FOR A FLASHING VISCOUS LIQUID IN A SPLASH PLATE NOZZLE (2015)

This article presents a new computational two-phase flow model and extensive validation for an industrial splash plate nozzle. The primary motivation for this work was to develop a simulation tool that can be used to reliably calculate initial droplet velocity data of industrial spray nozzles. This is an important part in properly defining boundary conditions for CFD furnace combustion simulations, for example, in the case of a recovery boiler burning black liquor. The model will also be actively used later for the industrial engineering and design of black liquor nozzle development. The model can also be used for other liquid fuels sprayed under flashing and nonflashing conditions. The model is based on the numerical solution of one-dimensional conservation equations of mass, momentum, energy, steam mass fraction, and bubble number density by using state of the art numerical methods that can track all the relevant mechanisms. Mass-momentum coupling was solved by the SIMPLE method. Scalar equations were solved by the fully implicit control volume method. A totally new and computationally efficient single-equation vapor generation source model was developed including heat transfer to bubble surface, evaporation, and inertial, viscous, and surface tension forces. Non-Newtonian effects were also included. The article presents comparison data for real flashing conditions with industrial black liquor, validating also the model predictions for initial spray velocity, nozzle pressure loss, and mass flow rate.
Effects of iron-oxide nanoparticles on compound biofilms of streptococcus gordonii and fusobacterium nucleatum (2018)

The human mouth is a host of a large gamut of bacteria species, with over 700 of different bacteria strains identified. Most of these bacterial species are harmless, some are beneficial (such as probiotics assisting in food digestion), but some are responsible for various diseases, primarily tooth decay and gum diseases such as gingivitis and periodontitis. Dental plaque has a complicated structure that varies from patient to patient, but a common factor in most cases is the single species of bacterium acting as a secondary colonizer, namely <i>Fusobacterium nucleatum</i>, while the actual disease is caused by a variety of tertiary colonizers. We hypothesize that destruction of a compound biofilm containing <i>Fusobacterium nucleatum</i> will prevent tertiary colonizers (oral pathogens) from establishing a biofilm, and thus will protect the patient from developing gingivitis and periodontitis. In this paper, we report on the effects of exposure of compound biofilms of a primary colonizer <i>Streptococcus gordonii</i> combined with <i>Fusobacterium nucleatum</i> to iron oxide nanoparticles as possible bactericidal agent.

Indoor target tracking using high doppler resolution passive Wi-Fi radar (2015)

This paper describes two Doppler only indoor passive Wi-Fi tracking methods based on high Doppler resolution passive radar. Two filters are investigated in this paper, the extended Kalman filter and the sequential importance resampling (SIR) particle filter. Experimental results for these two tracking filters are presented using results from software defined passive Wi-Fi radar using a standard 802.11 access point as an illuminator. The experimental results show that the SIR particle filter performs well using Wi-Fi signals for indoor tracking with a high degree of accuracy. Proposals for simplifying the SIR particle and application to multiple target tracking are also discussed.

Hall–Petch effect in binary and ternary alumina / zirconia / spinel composites (2021)

We present the Hall–Petch correlation between microhardness values and grain sizes for single, binary (50-50 vol.%), and ternary (33-33-33 vol.%) phase composites of yttria-stabilized zirconia (8Y–ZrO2), spinel (MgAl2O4), and alumina (Al2O3) samples produced by spark plasma sintering. Both the intrinsic grain microhardness values and the Hall–Petch constants were found to be significantly higher for alumina among the single-phase samples, and for the alumina-containing composites for the multiphase specimens. The microhardness values of all binary and ternary composites were observed to follow a rule of mixtures for both sub-micron (250–400 nm) and micrometer (1–1.5 μm) grain sizes. The fracture toughness values for all the specimens were also determined using the Vickers indentation method. Among all studied ceramic composites, single phase Al2O3 and a binary composite of 8Y–ZrO2/Al2O3 attained the highest hardness and toughness values of 20 GPa and 5.8 MPa•m1/2, respectively. The number of slip systems could be the main reason for the improved mechanical performance of the alumina and alumina-containing composites. Particularly, alumina consists of only 17 slip systems, while both zirconia and spinel are more ductile and contain 12 principal and 24 secondary, and 24 slip systems, respectively. These results are of significant interest, since they connect the grain sizes of the materials produced to their corresponding mechanical response.
[Split tibialis posterior tendon transfer on peroneus brevis for equinovarus foot in CP children]. (2007)

Equinovarus deformity of the foot is a result of the muscles imbalance in which inventors of the foot, mostly posterior and anterior tibialis muscle, overpower evertors. In children with cerebral palsy untreated spastic equinovarus deformity may cause severe fixed foot deformity and painful callosities under metatarsal heads and on the lateral side of the foot. The gait pattern becomes less effective and needs more energy. The study group consisted of 154 children with cerebral palsy treated in our Clinic by the multilevel soft tissue surgery. For foot problems 136 children needed surgical intervention. In 19 ambulatory patients, with hemiplegia or diplegia, split tibialis posterior tendon transfer together with tendo Achilles lengthening and plantar aponeurectomy were performed. The study was based on clinical examination, parents' questionnaire, radiology and gait analysis at least one year after surgery. The mean follow up was 4.6 years. The functional improvement was observed in 17 (89%) children with tendon transfer. At the last follow up those patients were brace free, with plantigrade foot while walking (without DAFO orthesis) and normal shoes were used. All painful callosities disappeared. On a standing AP X-ray adequate correction of the hindfoot-forefoot relation was achieved in 14 (74%) cases. Persistent equinovarus deformity over 10 degrees was observed in 2 cases. Those patients underwent additional bone surgery. With a properly planned approach the split tibialis posterior tendon transfer can bring good clinical and functional results in CP children with equinovarus deformation. We recommend this procedure in early stage of the deformity what can eliminate more harmful triple arthrodesis in severe deformities.
Mechanical Behavior of Erbium Oxide Single Crystals (2008)

Er2O3 single crystals were synthesized by optical floating zone single crystal techniques. The average room temperature hardness of these crystals was 7 GPa, while the average room temperature indentation fracture toughness was 0.86 MPa m1\2. Hardness decreased with increasing temperature, while fracture toughness increased at 1200 °C and above. Cleavage planes observed in erbia were {110} and {111}. Macroscopic compressive deformation occurred in erbia at 1640 °C. The observed slip system was {110}<111>.
The crustacean heart ultrastructure and its bearing upon the position of the isopods in eumalacostracan phylogeny (1987)

The present paper discusses the use of myocardial ultrastructure, and its merits, in studies of crustacean phylogeny. It is argued that different modifications of the heart do not affect the membrane systems of the myofibers and that the membrane systems are independent of size and/or adaptation of the species. Finally, the phylogenetic implications of the membrane systems are considered. Using the myocardial membrane systems in addition to the cephalothorax (carapace), compound eyes, respiratory system and heart anatomy, a new phylogenetic arrangement of the larger eumalacostracan orders (Anaspidacea, Amphipoda, Cumacea, Decapoda, Euphausiacea, Isopoda, Mysidacea, Tanaidacea) is suggested. The isopods are regarded as a sister group to the other eumalacostracans.
Starting and Stopping Services (2015)

This chapter covers the following init systems that have been used in Fedora, Red Hat Enterprise Linux, Ubuntu, and many other Linux distributions: SysVinit, Upstart and Systemd. In the process of using the init system that matches your Linux distribution, you learn how the boot process works to start services, how you can start and stop services individually, and how you enable and disable services. The initialization daemon can be thought of as the “mother of all processes.” The Linux init daemon was based upon the UNIX System V init daemon. Thus, it is called the SysVinit daemon. The Upstart init daemon depends upon events to trigger certain services to start, stop, restart, and so on. The Upstart init daemon emits the startup signal that triggers the service jobs to start. At server boot time, various jobs may themselves emit signals.
New fabrication method of InGaN laser diode by epitaxial lateral overgrowth and cleavable technique from free-standing non- and semi-polar GaN substrate (2021)

We propose a new Fabry-Perot (FP) GaN laser fabrication method utilizing an epitaxial lateral overgrowth (ELO) technique and m-plane cleavability of the GaN crystal. The removed m-plane InGaN laser having a lasing wavelength 408. 1 nm operated at a low threshold current density as low as 2.15 kA/cm<sup>2</sup>. First, unlike a conventional ELO growth technique, we avoid coalescence between adjacent ELO layers, thus forming island-like ELO layer bars, which were later used as the base for FP GaN laser. Then, a laser device epilayers were epitaxially grown and laser ridge structure was fabricated on each of these non-coalesced island-like ELO base layers. Island-like ELO laser bar formation facilitates an easy removal of the laser bars mechanically using a commercially available adhesive polymer film. Our investigation found that cleavable m-plane of the GaN crystal assists in the liftoff of the fabricated m-plane InGaN FP lasers. We further confirm that the reported fabrication method can be adopted to semi-polar crystal plane orientations of GaN.

They are guided by love and endeavour to help.
Entwicklung elektroosmotischer Mikropumpen für Lab-on-Mikrochips (2008)

Diese Arbeit fokussiert sich auf die Entwicklung und Charakterisierung elektroosmotischer Mikropumpen für Lab-on-Mikrochip-Anwendungen. Mikropumpen gehören zu den wichtigsten Komponenten des Labchips. Dabei sind mechanische Pumpen mit beweglichen Teilen aufgrund ihrer großen Abmessungen und komplizierten Konstruktionen nur mit großem Aufwand in Planartechnik integrierbar. Von den nichtmechanischen Mikropumpen mit elektrischer Ansteuerung sind elektroosmotische Pumpen von Bedeutung, da nach diesem Funktionsprinzip wässrige Lösungen mit sehr unterschiedlichen Leitfähigkeiten und pH-Werten gepumpt werden können. \nAC elektrokinetische Mikropumpen, bestehend aus auf dem Kanalboden angeordneten asymmetrischen Elektroden, ist einfach herzustellen, hat aber einen wesentlichen Nachteil: sie kann kaum einen Arbeitsdruck erzeugen und ist deswegen für den Einsatz in Labchips ungeeignet. Aus diesem Grunde konzentrierte sich die Entwicklung auf DC elektroosmotischen Mikropumpen.\nDie Konstruktion der DC elektroosmotischen Mikropumpe mit mehreren vertikal angeordneten schmalen Mikrokanälen aus dem Polymer SU-8 reduziert die Pumpenabmessungen, ermöglicht einen hohen Arbeitsdruck bei einer niedrigen Arbeitsspannung und ist kompatibel mit der Post-CMOS-Bearbeitung. Ein einfaches analytisches Modell zur Bestimmung der Pumpgeschwindigkeit im feldfreien Lastkanal wurde entwickelt und dargestellt.\nEin wesentliches Problem elektroosmotischer Mikropumpen ist die Wasserelektrolyse an den Metallelektroden. Die nachteilige Gasblasenbildung kann durch die Verwendung von gasdurchlässigen Deckeln aus Polydimethylsiloxan (PDMS) reduziert werden. Diese Lösung hat aber folgende Nachteile: die Arbeitsspannung wird auf einen schmalen Bereich von 4-5 V begrenzt und die hydrophobe Oberfläche von PDMS verhindert die Selbstbefüllung der Kanäle.\nEine optimale Lösung des Gasblasenproblems bietet die Positionierung der Metallelektroden in offenen Hilfsreservoiren außerhalb des Hauptkanals. Der Ionenstromfluss von Elektroden in den Hilfsreservoiren zum Pumpenbereich erfolgt durch die Gelelektroden. Mikropumpen mit den Gelelektroden aus dem fotopolymerisierten Polyacrylamid wurden gefertigt und untersucht. Die Pumprate ist bidirektional linear und beträgt etwa 10 nl/min in einem 1 cm langen Lastkanal bei der angelegten Spannung von 40 V, was einem maximalen Arbeitsdruck von 65 Pa entspricht. Zur weiteren Steigerung der Pumpleistungen muss das Aspektverhältnis von den Pumpenmikrokanälen durch die Reduzierung des Rippenabstandes erhöht werden.\nZur Messung der Pumprate und damit zur Steuerung der Mikropumpe wurde ein monolithisch integrierter Massenflusssensor entworfen, realisiert und untersucht. Eine programmierbare Pumpe als Kombination der elektroosmotischen Mikropumpe, des Massenflusssensors und einer externen Steuerelektronik wurde erfolgreich getestet. Hierbei konnten Pumpraten bis zu ±30 nl/min eingestellt werden. Die programmierbare Mikropumpe kann auch als aktives Ventil in Labchips eingesetzt werden.
Peptidylarginine Deiminase in Rat Pituitary: Sex Difference, Estrous Cycle-Related Changes, and Estrogen Dependence* (1989)

We have found notable sex difference in peptidylarginine deiminase (EC 3.5.3.15) in rat pituitaries. Pituitaries collected from 3-week to 6-month-old male rats, and those from 3-week-old females showed negligible enzyme activities. The enzyme activity of female pituitaries increased markedly by 2 months, and even further by 6 months of age. Measurements of the enzyme activity around the estrous cycle revealed its characteristic change, being high in the proestrus and estrus, and low in the metestrus and diestrus. These changes of the enzyme activity were shown to reflect changes of the actual amount of a single type of peptidylarginine deiminase by immunoprecipitation and immunoblotting analyses using an antiserum raised to an enzyme sample purified from rat skeletal muscle. The amount of pituitary enzyme was impoverished by ovariectomy. Repeated injections of 17 beta-estradiol to ovariectomized rats substantially restored the pituitary enzyme level. The above data suggest involvement of peptidylarginine deiminase in the female pituitary function.
Securing ad hoc routing protocols (2004)

Ad hoc networks are subject of many recent research efforts. Especially in mobile scenarios, self-organizing networks are of high interest. While the routing aspects of mobile ad hoc networks (MANETs) are already well understood, the research activities about security in MANETs are still at their beginning. MANETs pose a number of new security problems in addition to the problems of regular networks. In addition to the classical security threats we identified additional ways how nodes may attack security in an ad hoc network. We explore several aspects of possible (mis)behaviour of MANET participants. We introduce a systematology of attacks on a MANET. Further, we describe the results of simulations that show, how misbehaving nodes affect MANETs based on the DSR routing protocol. Finally we outline a security architecture that provides substantial security services for ad hoc networks.
Tumor cell migration in complex microenvironments (2012)

Tumor cell migration is essential for invasion and dissemination from primary solid tumors and for the establishment of lethal secondary metastases at distant organs. In vivo and in vitro models enabled identification of different factors in the tumor microenvironment that regulate tumor progression and metastasis. However, the mechanisms by which tumor cells integrate these chemical and mechanical signals from multiple sources to navigate the complex microenvironment remain poorly understood. In this review, we discuss the factors that influence tumor cell migration with a focus on the migration of transformed carcinoma cells. We provide an overview of the experimental and computational methods that allow the investigation of tumor cell migration, and we highlight the benefits and shortcomings of the various assays. We emphasize that the chemical and mechanical stimulus paradigms are not independent and that crosstalk between them motivates the development of new assays capable of applying multiple, simultaneous stimuli and imaging the cellular migratory response in real-time. These next-generation assays will more closely mimic the in vivo microenvironment to provide new insights into tumor progression, inform techniques to control tumor cell migration, and render cancer more treatable.

Plasma catalysis: A solution for environmental problems (2010)

The combination of a nonthermal, atmospheric plasma with a catalyst is investigated as a means of destroying pollutants in waste gas streams. Using the examples of dichloromethane (DCM) and toluene in air streams, it is shown that the destruction of the pollutant can be increased whilst lowering the operating temperature, giving increasing energy efficiency. Unwanted by-products can also be reduced selectively by appropriate choice of catalyst and of the plasma–catalyst configuration. By studying the temperature dependence of plasma catalysis, some ideas can be obtained about the nature of the interaction between plasma and catalyst in the processing.
Multi-wavelength regeneration of differentially phase-encoded signals using phase sensitive amplification (2012)

We summarize the results of our recent demonstration of the first multi-channel regenerator for phase encoded signals. By developing a novel inline phase sensitive amplification scheme simultaneous suppression of deterministic phase distortion on two independent 42.66 Gbit/s DPSK modulated signal wavelengths was achieved.
