Ansätze zur Qualitätsbewertung von generativen Fertigungsverfahren durch die Einführung eines Kennzahlensystems (2012)

RTejournal - Forum fur Rapid Technologie, Vol. 2012, Iss. 1 - Generative Fertigungsverfahren haben sich in den letzten Jahren als effektive Werkzeuge fur die schnelle Entwicklung von Produkten nahezu beliebiger Komplexitat entwickelt. Gleichzeitig wird gefordert, die Reproduzierbarkeit der Bauteile und auch seriennahe bzw. seriengleiche Eigenschaften zu gewahrleisten. Die Vielfalt und der Umfang der Anwendungen sowie die grose Anzahl verschiedener generativer Fertigungsverfahren verlangen adaquate Qualitatsuberwachungs- und Qualitatskontrollsysteme. Ein Losungsansatz fur die Qualitatsbewertung von generativen Fertigungsverfahren besteht in der Einfuhrung eines Kennzahlensystems. Hierzu mussen zunachst Anforderungsprofile und Qualitatsmerkmale fur generativ hergestellte Bauteile definiert werden, welche durch Prufkorpergeometrien abgebildet und mit Hilfe von Einzelkennzahlen klassifiziert werden. 
In Rahmen der durchgefuhrten Untersuchungen wurde die Qualitatsbewertung anhand von Prufkorpergeometrien am Beispiel des Laser-Sinterprozesses qualifiziert. Durch Beeinflussung der Prozessparameter, d.h. der gezielten Einbringung von Storgrosen, welche einzeln oder in Kombination zu unzulassigen Qualitatsschwankungen fuhren konnen, ist es moglich, die Qualitat des Produktes zu beurteilen. Die Definition von Einzelkennzahlen, die eine Steuerung und Kontrolle sowie eine Vorhersage potentieller Fehler ermoglicht, bietet hierbei essentielle Moglichkeiten zur Qualitatsbewertung. Eine Zusammenfuhrung zu einem gesamtheitlichen Kennzahlensystem soll zum einen den Prozess auf Grundlage der definierten Anforderungsprofile bewerten und zum anderen einen direkten Zusammenhang der ausgewahlten Storgrosen und Prozessgrosen herleiten, um vorab eine Aussage uber die Bauteilqualitat treffen zu konnen.
The Need for a “Swan Neck” Permanentl Y Bent, Arcuate Peritoneal Dialysis Catheter (1985)

In 1968 to ensure optimal function of a permanent catheter during periodic peritoneal dialysis, Tenckhoff recommended that a double-cuff catheter be inserted so that a slightly arcuate subcutaneous course would give the external and intraperitoneal segment a caudal direction. During the rapid growth of CAPD over the past five years, nephrologists generally have adapted the Tenckhoff's methods of catheter insertion but have encountered numerous complications. This paper describes a retrospective analysis of the complications associated with 83 peritoneal dialysis catheters functioned for 48,325 catheter days (132 catheter years) in 63 patients on continuous ambulatory peritoneal dialysis (CAPD) at our institution. Pericatheter leaks were seen only with midline insertions. Exit-site infections were significantly more resistant to treatment with singlecuff than with double-cuff catheters as assessed by the proportion of time that the exit-site is infected. If the subcutaneous tunnels were directed downward the infections were more responsive to treatment. Significantly more frequent catheter-tip migrations were observed with subcutaneous tunnel directed left and downward. Thus, our study supports Tenckhoff's observation that we can expect the lowest complication rate with double-cuff catheters with an arcuate tunnel, convex upwards. However, frequently this shape of tunnel is associated with external-cuff extrusions due to resilience of the straight catheter. To reconcile these conflicting requirements we recommend a new catheter permanently bent between the cuffs to eliminate one of the forces responsible for cuff extrusion. Such a catheter, named the swan-neck tunnel peritoneal dialysis catheter, should be inserted surgically through the belly of the rectus muscle.
Source excitation strategies for obtaining impulse responses in finite difference time domain room acoustics simulation (2014)

This paper considers source excitation strategies in finite difference time domain room acoustics simulations for auralization purposes. We demonstrate that FDTD simulations can be conducted to obtain impulse responses based on unit impulse excitation, this being the shortest, simplest and most efficiently implemented signal that might be applied. Single, rather than double, precision accuracy simulations might be implemented where memory use is critical but the consequence is a remarkably increased noise floor. Hard source excitation introduces a discontinuity in the simulated acoustic field resulting in a shift of resonant modes from expected values. Additive sources do not introduce such discontinuities, but instead result in a broadband offset across the frequency spectrum. Transparent sources address both of these issues and with unit impulse excitation the calculation of the compensation filters required to implement transparency is also simplified. However, both transparent and additive source excitation demonstrate solution growth problems for a bounded space. Any of these approaches might be used if the consequences are understood and compensated for, however, for room acoustics simulation the hard source is the least favorable due to the fundamental changes it imparts on the underlying geometry. These methods are further tested through the implementation of a directional sound source based on multiple omnidirectional point sources.
Dynamic Thermomagnetic Writing in Tunnel Junction Cells Incorporating Two GeSbTe Thermal Barriers (2006)

Magnetic tunnel junctions (MTJs) incorporating GeSbTe thermal barriers and weakly pinned free layers (H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ex</sub> ~60Oe) have been produced with areas between 1times1 mum <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and 3times8 mum <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . Current pulses lasting from 100 mus down to 20 ns were used to heat the MTJs and reverse the free layer pinning field.

Abstract Inkjet printing (IJP) technology is a popular technology for desktop publishing. In this abstract, we present the first successful demonstration of patterning the polymer electroluminescent devices using the IJP technology. The use of this concept represents a whole new technology of fabricating polyemr multicolor displays with high precision lateral patterning capability.
CLC transport proteins in plants (2009)

Nitrate compartmentalization in intracellular organelles has been long recognized as critical for plant physiology but the molecular identity of the proteins involved remained unclear for a long time. In Arabidopsis thaliana, AtClC-a has been recently shown to be a NO(3)(-)/H(+) antiporter critical for nitrate transport into the vacuoles. AtClC-a is a member of the CLC protein family, whose animal and bacterial members, comprising both channels and H(+)-coupled antiporters, have been previously implicated exclusively in Cl(-) transport. Despite the different NO(3)(-) over Cl(-) selectivity of AtClC-a compared to the other CLC antiporters, it has similar transport properties. Other CLC homologues have been cloned in Arabidopsis, tobacco, rice and soybean.

Application of a chemical group contribution technique for calculating solubility parameters of polymers (1979)

Abstract A chemical group contribution technique, based on the principle of additivity of molar attraction constants for groups in a molecule, has been used for determining the solubility parameters for several polyesters, polyethers and a few other types of polymers. The solubility parameter for a polymer is calculated by using the contributions for chemical groups reported in the literature with the resultant values found to compare favorably. For geometrical isomers of polymers, the calculated solubility parameters are identical but differ for positional substitution.
Rietveld refinement of the ranciéite structure using synchrotron powder diffraction data (2008)

Rietveld refinement using synchrotron powder X-ray diffraction data of the ranciéite, Ca 0.19 K 0.01 (Mn 4+ 0.91 ◻ 0.09 )O 2 ⋅0.63H 2 O, crystal structure reveals significant differences from that reported previously. The interlayer H 2 O molecules occupy sites halfway between the Mn,O octahedral sheets. The Mn sites in the octahedral sheets have 10% vacancies, and the mean Mn–O distance indicates that all Mn is tetravalent (Mn 4+ ). The interlayer Ca cations are located above and below the Mn vacancies and are octahedrally coordinated to three O 2 atoms in the octahedral sheet and three H 2 O molecules in the interlayer.
Improving the video streaming backend with on-the-fly format conversion and cloud storage (2018)

Online advanced media streaming services using HTTP adaptive stream-<br/>ing are increasingly popular. However in practice, the multi-protocol, multi-<br/>format nature of adaptive streaming creates a lot of engineering eort and<br/>costs for the operators, in the storage and preparation of the dierent<br/>formats. In this work, we acknowledge these issues and we study a stream-<br/>ing setup that can address these. Such streaming setup consist of a backend<br/>cloud storage and a processing node that generates streaming presentations<br/>for different devices on-the-fly. We analyse the streaming setup and its<br/>performance by testing in cloud deployments. Through this evaluation, we<br/>identify the performance limitations of the setup, imposed by the transfer<br/>of data between the object storage and the processing node. We propose a<br/>new backend storage caching scheme, based on rarely used existing feature<br/>of dref in the specication of the MPEG-4 standard. Experimental results<br/>show that the proposed scheme can improve the streaming performance,<br/>such as reduced latency and increased outgoing traffic volume towards the<br/>clients
Optimizing the reading of electronic text using rapid serial visual presentation (2001)

The focus on communications technology in recent years has led to the question of how to best display electronic text onto small-screened devices. Past studies have shown that the compact method of rapid serial visual presentation (RSVP) is efficient but not well liked. Two experiments were conducted to explore ways of improving the preference for and feasibility of RSVP. In experiment 1, the effects of a completion meter, punctuation pauses, and variable word duration were studied. Although the sentence-by-sentence and normal page formats were still superior, post-experiment ratings indicated that punctuation pauses improved user preference for RSVP, and its preference increased in general with practice. In experiment 2, a modified RSVP condition included a completion meter, punctuation pauses, interruption pauses and pauses at clause boundaries. This condition was significantly preferred to a normal RSVP condition. The present enhancements may increase the feasibility of using RSVP with small displays.
Short axial length broad-band horns (1973)

Ever-increasing antenna frequency bandwidth requirements for countermeasures applications and electromagnetic compatibility measurements have provided the impetus for the development of a series of very broad-band horns. In addition to the broad bandwidth, a substantial reduction in axial length over that of earlier models has been achieved for the two designs discussed in this communication. The first horn described covers the frequency range from 1.0-12.0 GHz with the flared portion of the horn having an axial length of 6 in as compared with 12 in for an earlier model. Although horn antennas are not commonly considered for use at frequencies as low as 0.2 GHz, the short axial length design appeared to be an attractive approach in developing a very reasonably sized antenna operating in the 0.2-2.0 GHz range. The technique of fabricating the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">H</tex> plane walls in the form of a grid was used in both designs as a means of maintaining the required <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">H</tex> -plane half-power beamwidths. The grid for the 1.0-12.0 GHz horn is of printed circuit form while the grid elements of the lower frequency horn are made of aluminum tubing. Electrical characteristics of both designs are presented, as well as some additional data for recent advances which indicate that a further reduction in axial length or an increase in bandwidth can be achieved with only a moderate rise in VSWR in the lower portion of the frequency range.
The erbB2 gene is required for the development of terminally differentiated spinal cord oligodendrocytes (2001)

Development of oligodendrocytes and the generation of myelin internodes within the spinal cord depends on regional signals derived from the notochord and axonally derived signals. Neuregulin 1 (NRG)-1, localized in the floor plate as well as in motor and sensory neurons, is necessary for normal oligodendrocyte development. Oligodendrocytes respond to NRGs by activating members of the erbB receptor tyrosine kinase family. Here, we show that erbB2 is not necessary for the early stages of oligodendrocyte precursor development, but is essential for proligodendroblasts to differentiate into galactosylcerebroside-positive (GalC+) oligodendrocytes. In the presence of erbB2, oligodendrocyte development is normal. In the absence of erbB2 (erbB2-/-), however, oligodendrocyte development is halted at the proligodendroblast stage with a >10-fold reduction in the number of GalC+ oligodendrocytes. ErbB2 appears to function in the transition of proligodendroblast to oligodendrocyte by transducing a terminal differentiation signal, since there is no evidence of increased oligodendrocyte death in the absence of erbB2. Furthermore, known survival signals for oligodendrocytes increase oligodendrocyte numbers in the presence of erbB2, but fail to do so in the absence of erbB2. Of the erbB2-/- oligodendrocytes that do differentiate, all fail to ensheath neurites. These data suggest that erbB2 is required for the terminal differentiation of oligodendrocytes and for development of myelin.
The Behavior of Hydrocolloid Coatings on Vegetative Materials (1998)

Coating vegetative materials by gelling agents is a process characterized by four different time scales. After wetting and penetration of the vegetative skin by the gum solution, adhesion of the viscous solution to the outer layer (skin) of the coated material is possible. The gelled film (coating) collapses during further drying and adheres to the vegetative tissue. Critical surface tensions of the solid object to be coated, its apparent and real roughness, wettability of the surfaces by the gum solution, the composition and polarity of the films designed to coat the solid, and the surface tension of gum coating solutions are among the critical properties that need to be explored and changed for a successful coating process. The critical surface tensions of garlic peel and gellan and alginate films (coatings) were evaluated by Zisman plots. Garlic skin has a low surface tension compared with those of synthetic films such as polystyrene and polyethylene. A spreading technique was used to determine the surface tension of the dry film and the solid garlic skin. Surface tension was divided into dispersive and polar components. The similarity between the coating solution and the object to be coated in values of dispersive and polar components influences the spreadability of the coating gum solutions. Better compatibility between the coated object and the coating films can be achieved by incorporating surface-active agents within the coating gum solution. From the compatibility requirements detailed above, it can be concluded that tailor-made hydrocolloid coatings for different vegetative materials can only be achieved by further exploring the chemical and physical properties of the coating solutions and the coated objects.
Control of Regulatory T Cell Migration, Function, and Homeostasis (2015)

Foxp3(+) regulatory T cells (Tregs) are essential for preventing autoimmunity and uncontrolled inflammation, and they modulate immune responses during infection and the development of cancer. Accomplishing these tasks requires the widespread distribution of Tregs in both lymphoid and nonlymphoid tissues, and the selective recruitment of Tregs to different tissue sites has emerged as a key checkpoint that controls tissue inflammation in autoimmunity, infection, and cancer development, as well as in the context of allograft acceptance or rejection. Additionally, Tregs are functionally diverse, and it has become clear that some of this diversity segregates with Treg localization to particular tissue sites. In this article, I review the progress in understanding the mechanisms of Treg trafficking and discuss factors controlling their homeostatic maintenance and function in distinct tissue sites.

Effects of adenosine on atrial refractoriness and arrhythmias (1994)

Adenosine produces a receptor mediated shortening of monophasic action potential duration and refractoriness which increases vulnerability to transient atrial arrhythmias. During sustained atrial flutter, these effects may also contribute to destabilisation and termination of the arrhythmia.
Hedgehog-interacting protein is highly expressed in endothelial cells but down-regulated during angiogenesis and in several human tumors (2004)

These results suggest that reduced expression of HIP, a naturally occurring Hh pathway antagonist, in tumor neo-vasculature may contribute to increased Hh signaling within the tumor and possibly promote angiogenesis.
[Effect of injection of a phosphorylcholine-containing compound from Nippostrongylus brasiliensis on the infestation of the rat by this parasite]. (1975)

Rats were injected intradermally with the purified phosphorycholine bearing component of the nematode Nippostrongylus brasiliensis. Eight days later they were experimentally infected with 1 X 10(3) infective larvae of the parasite. Compared to the non injected controls we showed a significant decrease in the number of adult worms able to be established in the small intestine. This protective effect seems to be due at least partly to a phenomenom being located between the skin and the lungs of the rats.
Prediction and Measurement of Wind Response: Case Story of a Wind Sensitive Building (1987)

The wind-induced horizontal accelerations of a 43 story office tower in New York City were monitored during 11 occasions over a period of about six months. The building dates back to the early sixties and is of typical steel frame construction with a block core located eccentrically at one end. Records of wind-induced accelerations were made during both calm and windy conditions. The latter included strong winds during Hurricane Gloria in September of 1985 and during a relatively severe extra-tropical storm. The objectives of the monitoring program were twofold: i) to obtain estimates of building periods and its damping as required in the assessment of its resistance to wind loads; and ii) to compare the observed wind-induced response with predictions from a wind tunnel model study of the building carried out to assist in the re-evaluation of the building.
Effect of formulation variables on in vitro drug release and micromeritic properties of modified release ibuprofen microspheres (1999)

Modified release microspheres of the non-steroidal anti-inflammatory drug, ibuprofen, were formulated and prepared using the emulsion solvent diffusion technique. The contribution of various dispersed phase and continuous phase formulation factors on in vitro drug release and micromeritic characteristics of microspheres was examined. The results demonstrated that the use of Eudragit RS 100 and Eudragit RL 100 as embedding polymers modified the drug release properties as a function of polymer type and concentration. Eudragit RS 100 retarded ibuprofen release from the microspheres to a greater extent than Eudragit RL 100. The drug/polymer concentration of the dispersed phase influenced the particle size and drug release properties of the formed microspheres. It was found that the presence of emulsifier was essential for microsphere formation. Increasing the concentration of emulsifier, sucrose fatty acid ester F-70, decreased the particle size which contributed to increased drug release properties. Scanning electron microscopy revealed profound distortion in both the shape and surface morphology of the microspheres with the use of magnesium stearate as added emulsifier. The application of an additional Eudragit RS 100 coat onto formed microspheres using fluid bed technology was successful and modulated the drug release properties of the coated microspheres.
